技术领域technical field
本发明涉及一种光学组件，特别涉及一种适用于条码读取装置的影像撷取器中的光学组件。The invention relates to an optical component, in particular to an optical component suitable for an image picker of a barcode reading device.
背景技术Background technique
随着光学编码技术的提升，条码系统已取代繁复的人工输入方式，而广泛地使用于各种领域中，并具有方便控管货品物料、文书处理建档、及迅速判断商品价格等优点。而要读取各条码中所包含的信息，则需通过条码扫描器(barcode reader)。条码扫描器主要利用影像撷取器撷取条码影像后，经由影像处理程序将条码内的数据分析出来，以利后续应用。而无论一维或是二维的条码读取装置中，都是经由设置一影像撷取器，来进行条码的扫描与读取，以得到条码中的数据。With the improvement of optical coding technology, the barcode system has replaced the complicated manual input method, and is widely used in various fields, and has the advantages of convenient control of goods and materials, document processing and filing, and rapid judgment of commodity prices. To read the information contained in each barcode, a barcode reader is required. The barcode scanner mainly uses the image capture device to capture the barcode image, and then analyzes the data in the barcode through the image processing program to facilitate subsequent applications. Regardless of the one-dimensional or two-dimensional barcode reading device, an image capture device is installed to scan and read the barcode to obtain the data in the barcode.
用以读取并编译条码系统的影像撷取器，其内部通常会设置有一发光二极管，以产生一光线，并在发光二极管外设置所需的光学元件，如透镜以及扩散片等。在位于光线投射路径上的光学构件的引导下，得以对条码符号进行扫描，并将条码符号中的有码区的宽度与间距反射至条码扫描器内，以判别所扫描的条码符号。An image capture device for reading and compiling a barcode system usually has a light-emitting diode inside to generate a light, and required optical elements, such as a lens and a diffuser, are arranged outside the light-emitting diode. Under the guidance of the optical component located on the light projection path, the barcode symbol can be scanned, and the width and spacing of the coded area in the barcode symbol are reflected into the barcode scanner to distinguish the scanned barcode symbol.
另外，为让使用者能将条码置于条码扫描器所能读取的范围内，影像撷取器内会再设置一准直光源及相对应的光学元件，藉以在投射出一扫描区域，让使用者能将条码置于影像撷取视角的中心。In addition, in order to allow the user to place the barcode within the range that the barcode scanner can read, a collimated light source and corresponding optical elements will be set in the image capture device to project a scanning area so that The user can place the barcode at the center of the image capture angle of view.
现有的影像撷取器是分别生产各个光学元件后，再分别固定至各光源前方或所需位置。由于为能投射出较大范围以能快速读取范围内的条码信息，或能发出较高亮度光源以利在户外使用，多会组设多个发光元件。而在每一个发光元件前亦再设置相对应的光学元件，因而增加光学元件的数量，并使得组装工序更为繁复。In the existing image capture device, each optical element is produced separately, and then fixed to the front of each light source or to a desired position. In order to be able to project a larger range to quickly read the barcode information within the range, or to emit a higher brightness light source for outdoor use, multiple light-emitting elements are usually assembled. Corresponding optical elements are arranged in front of each light-emitting element, thereby increasing the number of optical elements and making the assembling process more complicated.
另外，为使条码扫描器中的影像撷取器能尽可能微型化以适用于各种电子装置，如手机、PDA等，光学元件的大小亦需跟着最小化。因此，亦提升了设置、定位各光学元件的难度，并有可能使得良率降低。In addition, in order to make the image capture device in the barcode scanner as miniaturized as possible to be suitable for various electronic devices, such as mobile phones, PDAs, etc., the size of the optical components must also be minimized. Therefore, it also increases the difficulty of arranging and positioning each optical element, and may reduce the yield rate.
发明内容Contents of the invention
有鉴于此，本发明提出一种影像撷取器的光学组件，包括：一基板以及二光学透镜。基板具有一穿孔、一凹槽与相对的二长侧边。穿孔位于二长侧边之间，凹槽自基板的其中一表面朝另一表面凹设而凸出于另一表面，且凹槽位于其中一长侧边的一端。二光学透镜则是分别凸设于基板的另一表面，且位于基板的另一长侧边的二端，二光学透镜与基板为一体成型且不可分离的结构。In view of this, the present invention proposes an optical component of an image capture device, including: a substrate and two optical lenses. The substrate has a through hole, a groove and two opposite long sides. The through hole is located between the two long sides, the groove is recessed from one surface of the substrate toward the other surface and protrudes from the other surface, and the groove is located at one end of one of the long sides. The two optical lenses are respectively protruded on the other surface of the substrate and located at two ends of the other long side of the substrate. The two optical lenses and the substrate are integrally formed and inseparable.
另外，本发明亦提出一种影像撷取器，包括：一本体、一第一电路板、一影像撷取镜头、一准直光源、一第二电路板、二发光元件、及上述的光学组件。本体包括一第一通孔及一第二通孔。第一电路板则是固设于本体，影像撷取镜头则是设置于第一通孔中，并电性连接至第一电路板。准直光源设置于第一电路板且对应本体的第二通孔。第二电路板是固设于本体相对于第一电路板的一侧，二发光元件则是设置于第二电路板上。光学组件设置于第二电路板上且固接于本体。光学组件上的二光学透镜会分别对应覆盖二发光元件，凸盖则对应覆盖第二通孔。In addition, the present invention also proposes an image capture device, including: a body, a first circuit board, an image capture lens, a collimated light source, a second circuit board, two light emitting elements, and the above-mentioned optical components . The body includes a first through hole and a second through hole. The first circuit board is fixed on the body, and the image capture lens is arranged in the first through hole and electrically connected to the first circuit board. The collimated light source is arranged on the first circuit board and corresponds to the second through hole of the body. The second circuit board is fixed on the side of the main body opposite to the first circuit board, and the two light emitting elements are arranged on the second circuit board. The optical component is arranged on the second circuit board and fixed on the body. The two optical lenses on the optical assembly cover the two light-emitting elements respectively, and the convex cover covers the second through hole correspondingly.
本发明通过将影像撷取器所需使用的光学元件，如发光元件用的光学透镜，直接结合于覆盖于影像撷取器前端的基板上。使光学透镜与基板为一体成型式结构，在制作基板时，亦可同时制成所需的光学透镜，同时减少了制造元件数量、时间及成本。而在组装时，仅需将基板锁固至影像撷取器的本体上，即可完成组装设置前面板及光学元件。因不需要一一进行各光学元件的粘固或设置，可大幅简化组装程序，缩短组装时间。再者，光学元件于成形时即同时完成定位，亦解决了因光学元件设置位置偏移而成为不良品，造成良率降低的问题。In the present invention, the optical components required by the image capture device, such as the optical lens for the light-emitting device, are directly combined on the substrate covering the front end of the image capture device. The optical lens and the base plate are integrally formed, and the required optical lens can also be produced at the same time when the base plate is produced, while reducing the number of manufacturing components, time and cost. When assembling, it is only necessary to lock the substrate to the body of the image capture device, and then the assembly and installation of the front panel and optical components can be completed. Since there is no need to glue or set each optical element one by one, the assembly procedure can be greatly simplified and the assembly time can be shortened. Furthermore, the positioning of the optical element is completed at the same time when forming, which also solves the problem of defective products caused by the offset of the optical element's installation position, resulting in a decrease in yield.

下面结合附图对本发明的结构原理和工作原理作具体的描述：Below in conjunction with accompanying drawing, structural principle and working principle of the present invention are specifically described:
请参阅图1及图2，其分别为本发明第一实施例不同视角的光学组件的立体图。本实施例的光学组件10包括一基板11、二光学透镜12、及一准直光学元件。基板11具有一穿孔111、一凹槽112与相对的二长侧边113、114。穿孔111位于二长侧边113、114之间。凹槽112自基板11的第二表面116朝第一表面115凹设而凸出于第一表面115，且凹槽112位于其中一长侧边的一端。如图1所示，凹槽112位于长侧边113的一端。Please refer to FIG. 1 and FIG. 2 , which are respectively three-dimensional views of optical components with different viewing angles according to the first embodiment of the present invention. The optical component 10 of this embodiment includes a substrate 11 , two optical lenses 12 , and a collimating optical element. The substrate 11 has a through hole 111 , a groove 112 and two opposite long sides 113 , 114 . The through hole 111 is located between the two long sides 113 , 114 . The groove 112 is recessed from the second surface 116 of the substrate 11 toward the first surface 115 and protrudes from the first surface 115 , and the groove 112 is located at one end of one of the long sides. As shown in FIG. 1 , the groove 112 is located at one end of the long side 113 .
二光学透镜12分别凸设于11基板的第一表面115，且位于基板11的另一长侧边的二端。如图1所示，二光学透镜12位于长侧边114的二端。二光学透镜12与基板11是为一体成型且不可分离的结构，因此在制造基板时，可同时形成二光学透镜12。如此可减少元件数量及制造时间，并同时降低制造成本。The two optical lenses 12 are respectively protruding from the first surface 115 of the substrate 11 and located at two ends of the other long side of the substrate 11 . As shown in FIG. 1 , the two optical lenses 12 are located at two ends of the long side 114 . The two optical lenses 12 and the substrate 11 are integrally formed and inseparable. Therefore, when manufacturing the substrate, the two optical lenses 12 can be formed at the same time. In this way, the number of components and manufacturing time can be reduced, and the manufacturing cost can be reduced at the same time.
在本实施例中的准直光学元件为一绕射光学元件13设置于凹槽112中，且在凹槽112的中心处具有一透孔1121。在图1中，透孔1121的形状为一圆形，然而其亦可为方形、菱形、椭圆形或不规则形状等，只要能让准直光线透出即可。本实施例中考量到制造上的方便是采用圆形。The collimating optical element in this embodiment is a diffractive optical element 13 disposed in the groove 112 and has a through hole 1121 at the center of the groove 112 . In FIG. 1 , the shape of the through hole 1121 is a circle, but it can also be a square, rhombus, ellipse or irregular shape, as long as the collimated light can pass through. Considering the convenience of manufacture in this embodiment, a circular shape is used.
接着请参阅图3及图4，其分别为本发明第一实施例影像撷取器20的立体图及分解图。本实施例的影像撷取器20包括：一本体21、一第一电路板22、一影像撷取镜头23、一准直光源、一第二电路板25、二发光元件26、上述的光学组件10。本体21包括一第一通孔211及一第二通孔212。如图4所示，第一通孔211位于本体11的中央处，而第二通孔212则可位于第一通孔211左右任一侧。Next, please refer to FIG. 3 and FIG. 4 , which are respectively a perspective view and an exploded view of the image capture device 20 according to the first embodiment of the present invention. The image capture device 20 of this embodiment includes: a body 21, a first circuit board 22, an image capture lens 23, a collimated light source, a second circuit board 25, two light emitting elements 26, and the above-mentioned optical components 10. The body 21 includes a first through hole 211 and a second through hole 212 . As shown in FIG. 4 , the first through hole 211 is located at the center of the body 11 , and the second through hole 212 can be located at either side of the first through hole 211 .
第一电路板22固设于本体21的下表面。另外，第一电路板22可包括一感光元件222，且感光元件222会对应第一通孔211，且会电性连接至第一电路板22。影像撷取镜头23是设置于第一通孔211中。准直光源是设置于第一电路板22且对应第二通孔212。在本实施例中，准直光源为一激光光源24，且会穿设于第二通孔212中。第二电路板25固设于本体21相对于第一电路板22的一侧，即在本体21的上表面。二发光元件26设置于第二电路板25上，且位于第二电路板25上相对应的二侧边。The first circuit board 22 is fixed on the lower surface of the main body 21 . In addition, the first circuit board 22 may include a photosensitive element 222 , and the photosensitive element 222 corresponds to the first through hole 211 and is electrically connected to the first circuit board 22 . The image capture lens 23 is disposed in the first through hole 211 . The collimated light source is disposed on the first circuit board 22 and corresponds to the second through hole 212 . In this embodiment, the collimated light source is a laser light source 24 , and is disposed in the second through hole 212 . The second circuit board 25 is fixed on a side of the body 21 opposite to the first circuit board 22 , that is, on the upper surface of the body 21 . The two light emitting elements 26 are disposed on the second circuit board 25 and located on two corresponding sides of the second circuit board 25 .
前述的光学组件10则设置于第二电路板25上且固接于本体21。如图3、图4所示，当光学组件10覆盖至第二电路25上时，二光学透镜12会分别对应覆盖二发光元件26，且凹槽112会对应覆盖第二通孔212。且在本实施例中是利用三螺丝14穿过光学组件10及第二电路板25再锁固至本体21，以将光学组件10固接于本体21。The aforementioned optical component 10 is disposed on the second circuit board 25 and fixed to the body 21 . As shown in FIGS. 3 and 4 , when the optical component 10 covers the second circuit 25 , the two optical lenses 12 cover the two light emitting elements 26 respectively, and the groove 112 covers the second through hole 212 correspondingly. And in this embodiment, three screws 14 are used to pass through the optical component 10 and the second circuit board 25 and then locked to the main body 21 to fix the optical component 10 to the main body 21 .
由于将影像撷取器20所需的光学元件，如发光元件26用的光学透镜12及准直光源用的准直光学元件全部都设置于光学组件10上。因此，仅需将光学组件10锁固至影像撷取器20的本体21上，即完成多个光学元件的组设。且由于各光学元件在制造光学组件10时，已准确设置于所需位置，在组设时不需要另外进行定位，亦可避免光学元件设置位置偏移。因此，可大幅简化组装程序，缩短组装时间，同时解决良率降低的问题。Because the optical elements required by the image pickup device 20 , such as the optical lens 12 for the light emitting element 26 and the collimating optical element for collimating the light source, are all arranged on the optical assembly 10 . Therefore, only the optical assembly 10 needs to be locked to the body 21 of the image capture device 20 to complete the assembly of multiple optical elements. Moreover, since each optical element has been accurately set at the desired position when the optical component 10 is manufactured, no additional positioning is required during assembly, and positional displacement of the optical element can also be avoided. Therefore, the assembly procedure can be greatly simplified, the assembly time can be shortened, and the problem of yield reduction can be solved at the same time.
接着请参阅图5A、图5B及图5C，其分别为本发明第一实施例的影像撷取器20使用不同的绕射光学元件所形成的准直图案。使用者可根据需求去设计所想形成的准直图案，而进一步去组设相对应的绕射光学元件于本实施例的影像撷取器20中，以提升使用者判断条码可读取范围的准确度。如图5A所示的准直图案27，为中间以一具圆点的十字271代表中心位置，而最大可读取范围的四个角落分别以一大圆点272表示，以示意影像撷取器20的可读取范围。Please refer to FIG. 5A , FIG. 5B and FIG. 5C , which are the collimation patterns formed by the image capture device 20 according to the first embodiment of the present invention using different diffractive optical elements. Users can design the collimation pattern they want to form according to their needs, and further set up corresponding diffractive optical elements in the image capture device 20 of this embodiment, so as to improve the user's ability to judge the readable range of barcodes. Accuracy. In the collimation pattern 27 shown in FIG. 5A, a cross 271 with a dot in the middle represents the central position, and the four corners of the maximum readable range are respectively represented by a large dot 272 to indicate the image pickup device. 20 readable range.
而图5B所示的准直图案28，同样是以一具圆点的十字281做为中心位置，但将十字中间的圆点放大，让中点的对位可更为容易。另外，最大可读取范围除四个角落除了有一大圆点282外，各大圆点282间的中间位置亦有一小圆点283，以使可读取范围更为明确。The collimation pattern 28 shown in FIG. 5B also uses a dotted cross 281 as the center position, but the dot in the middle of the cross is enlarged to make alignment of the midpoint easier. In addition, in addition to the large dots 282 at the four corners of the maximum readable range, there is also a small dot 283 in the middle of the large dots 282 to make the readable range clearer.
另外，亦可如图5C所示的准直图案29，中间仅以一不含圆点的十字291表示中心位置。而最大可读取范围则是在四个角落以一横线292表示，当要读取为方形或矩形的条码时，横线292可较容易判断条码是否有位于可读取位置内或进行调整。In addition, the collimation pattern 29 as shown in FIG. 5C may also have a cross 291 without a dot in the middle to indicate the center position. The maximum readable range is indicated by a horizontal line 292 at the four corners. When a square or rectangular barcode is to be read, the horizontal line 292 can easily determine whether the barcode is located in the readable position or adjust it. .
接着请参阅图6及图7，其分别为本发明第二实施例光学组件及使用该光学组件的影像撷取器的立体图。本实施例的光学组件30与第一实施例相同之处以同样元件符号表示且不再赘述。不同之处在于，本实施例的准直光学元件是为一光栅元件33。在本实施例中，光栅元件33为一二维光栅元件，在其他态样下，亦可使用一维光栅元件，本发明不以此为限。Next, please refer to FIG. 6 and FIG. 7 , which are perspective views of an optical component and an image capture device using the optical component, respectively, according to a second embodiment of the present invention. The optical component 30 of this embodiment is identical to the first embodiment with the same component symbols and will not be described again. The difference is that the collimating optical element in this embodiment is a grating element 33 . In this embodiment, the grating element 33 is a two-dimensional grating element. In other aspects, a one-dimensional grating element can also be used, and the present invention is not limited thereto.
光栅元件33是设置于基板11的凹槽112。且光栅元件33可利用紧配、粘固或是一体成型的方式设置于基板11的凹槽112。在本实施例中，光栅元件33与基板11的凹槽112为一体成型且不可分离的结构。其是在射出成型基板11的同时亦形成光栅元件33。如此，可减少各元件的制造及组装时间，以缩短工艺并降低制造成本。The grating element 33 is disposed on the groove 112 of the substrate 11 . In addition, the grating element 33 can be disposed in the groove 112 of the substrate 11 by means of tight fit, adhesion or integral molding. In this embodiment, the grating element 33 and the groove 112 of the substrate 11 are integrally formed and inseparable. It is to form the grating element 33 at the same time when the substrate 11 is injection-molded. In this way, the manufacturing and assembly time of each element can be reduced, so as to shorten the process and reduce the manufacturing cost.
在其他态样中，亦可在凹槽穿设一矩型孔洞，再将光栅元件33以紧配或粘合的方式置入矩型孔洞中，与基板的凹槽结合。此种方式适用于需要使用结构较细密的光栅元件的情形。因为一般塑胶射出成型无法形成过于细密的结构，因此可通过其他如半导体工艺的方式先制成所需的光栅元件后，再组设至基板的凹槽。再者，此种设置方式亦提供元件替换的灵活性，当要将光栅元件由一维光栅元件更换为二维光栅元件的话，亦仅需进行光栅元件的替换，而不需要重制整个光学组件。In other aspects, a rectangular hole may also be formed in the groove, and then the grating element 33 is inserted into the rectangular hole in a tight fitting or bonding manner to combine with the groove of the substrate. This method is suitable for the situation where a grating element with a finer structure is required. Because general plastic injection molding cannot form too fine a structure, the required grating elements can be manufactured first by other methods such as semiconductor technology, and then assembled to the grooves of the substrate. Furthermore, this arrangement method also provides flexibility in component replacement. When the grating component is to be replaced from a one-dimensional grating component to a two-dimensional grating component, only the grating component needs to be replaced, and the entire optical assembly does not need to be remade. .
另外，由于使用光栅元件33做为准直光学元件，其较适合使用激光光源做为准直光源，以使光线能通过光栅元件形成所需准直图样。因此，本实施例的影像撷取元件40亦同第一实施例是使用激光光源24做为准直光源。In addition, since the grating element 33 is used as the collimating optical element, it is more suitable to use a laser light source as the collimating light source, so that the light can pass through the grating element to form the required collimation pattern. Therefore, the image capture device 40 of this embodiment also uses the laser light source 24 as the collimated light source as in the first embodiment.
接着请参阅图8及图9，其分别为本发明第三实施例光学组件及使用该光学组件的影像撷取器的立体图。本实施例的光学组件50与第一实施例相同之处以同样的元件符号表示且不再赘述。不同之处在于，本实施例的准直光学元件是为一光学扩散元件53。且由图8可见，本实施例的光学扩散元件53与基板11的凹槽112为一体成型且不可分离的结构。在其他态样中，亦可将凹槽穿设一圆形孔洞，再将光学扩散元件以紧配或粘合的方式置入凹槽中与基板结合，并使光学扩散元件的中心位于圆形孔洞处。在本实施例中使用一体成型的方式，可减少各元件的制造及组装时间，以缩短工艺并降低制造成本。Next, please refer to FIG. 8 and FIG. 9 , which are perspective views of an optical component and an image capture device using the optical component, respectively, according to a third embodiment of the present invention. The optical component 50 of this embodiment is identical to the first embodiment with the same reference numerals and will not be repeated here. The difference is that the collimating optical element in this embodiment is an optical diffusing element 53 . It can be seen from FIG. 8 that the optical diffusing element 53 and the groove 112 of the substrate 11 in this embodiment are integrally formed and inseparable. In other aspects, the groove can also be pierced with a circular hole, and then the optical diffusion element can be put into the groove and combined with the substrate in a tight fit or bonding manner, and the center of the optical diffusion element is located in the circular hole. at the hole. In this embodiment, the one-piece molding method is used, which can reduce the manufacturing and assembly time of each component, thereby shortening the process and reducing the manufacturing cost.
另外，本实施例的影像撷取器60与第一实施例不同之处在于使用的准直光源包括一发光二极管641及一光圈元件642。如图9所示，发光二极管641设置于第一电路板22，而光圈元件642则设置于本体21靠近发光二极管641的一侧，并覆盖第二通孔212。由发光二极管641发出的准直光线通过光圈元件642后，再经过光学扩散元件53后投射出，以表示影像撷取镜头23的可读取范围的中心。In addition, the difference between the image capture device 60 of this embodiment and the first embodiment is that the collimated light source used includes a light emitting diode 641 and an aperture element 642 . As shown in FIG. 9 , the LED 641 is disposed on the first circuit board 22 , and the aperture element 642 is disposed on the side of the body 21 close to the LED 641 and covers the second through hole 212 . The collimated light emitted by the LED 641 passes through the aperture element 642 and is projected out after passing through the optical diffusion element 53 to represent the center of the readable range of the image capturing lens 23 .
由上述三个实施例可知，本发明的光学组件，可配合所需使用的准直光源而设置相对应的准直光学元件，以符合使用需求。且无论搭配合何种准直光学元件，皆可设置于本发明的光学组件上，使得影像撷取器所需的光学元件皆在同一个组件上。如此，以减少了制造元件数量、时间及成本，并大幅简化组装程序，缩短组装时间，且亦提供了元件替换的灵活性。It can be seen from the above three embodiments that the optical assembly of the present invention can be equipped with corresponding collimating optical elements in accordance with the required collimating light source, so as to meet the requirements of use. And no matter what kind of collimating optical element is used, it can be arranged on the optical component of the present invention, so that the optical elements required by the image capture device are all on the same component. In this way, the quantity, time and cost of manufacturing components are reduced, the assembly procedure is greatly simplified, the assembly time is shortened, and the flexibility of component replacement is also provided.
