射频识别读写器天线设计需要在工作频段获得高增益已完成可靠识别的应用要求，而电子标签天线的响应频段十分敏感直接接触的介质，常会出现电子标签安置于一些物体表面就无法识别的问题。而对于射频识别读写器来说，电子标签将直接和射频识别读写器表面接触，会导致电子标签的响应频段偏移，而读写器发射的射频信号频段是按原响应频段设计的，不能够跟随电子标签的频率偏移而偏移，这样就会出现读写器对电子标签进行读写操作困难的情况。The antenna design of the radio frequency identification reader needs to obtain high gain in the working frequency band to complete the application requirements of reliable identification, while the response frequency band of the electronic tag antenna is very sensitive to the medium in direct contact, and the problem that the electronic tag cannot be recognized when it is placed on the surface of some objects often occurs . For RFID readers, the electronic tag will directly contact the surface of the RFID reader, which will cause the response frequency band of the electronic tag to shift, and the frequency band of the RF signal emitted by the reader is designed according to the original response frequency band. It cannot follow the frequency offset of the electronic tag, so that it will be difficult for the reader to read and write the electronic tag.

具体实施方式detailed description
为了能更清楚地理解本发明的技术内容，特举以下实施例详细说明。In order to understand the technical content of the present invention more clearly, the following examples are given in detail.
请参阅图1和图2，该托台型射频识别读写装置，包括读写装置承载主体1和射频标签读写平台2，读写装置承载主体1内设置有射频识别天线，射频标签读写平台2位于读写装置承载主体1的上方，射频标签读写平台2用于放置电子标签，射频标签读写平台2的上表面设置有限位托台3，电子标签具有相互垂直的长边和宽边，电子标签沿平行于其长边或宽边移动时均由限位托台3进行限位，且电子标签设置于限位托台3所限定的位置时，该电子标签与其下方的射频识别天线的位置相对应，使用者在使用时，只需将携带的电子标签置于限位托台3所限定的位置处，即可快速读取，避免了使用者需要在射频标签读写平台2表面的多个位置进行尝试性的刷卡，大大节约了使用者的时间。Please refer to Fig. 1 and Fig. 2, this pallet type radio frequency identification read-write device, comprises read-write device carrying main body 1 and radio frequency label read-write platform 2, is provided with radio frequency identification antenna in the main body 1 of read-write device, radio frequency tag reads and writes The platform 2 is located above the main body 1 of the read-write device. The radio-frequency tag read-write platform 2 is used to place electronic tags. The upper surface of the radio-frequency tag read-write platform 2 is provided with a limited bracket 3. When the electronic tag moves parallel to its long side or wide side, it is limited by the limit bracket 3, and when the electronic tag is set at the position limited by the limit bracket 3, the electronic tag and the radio frequency identification below it The positions of the antennas correspond to each other. When users are using it, they only need to place the electronic tag they carry at the position limited by the limit bracket 3 to read it quickly, which avoids the need for the user to read and write the tag on the radio frequency tag reading and writing platform 2. Attempts to swipe the card at multiple positions on the surface greatly save the user's time.
现有的射频识别读写装置大都是在壳体内设置天线，进行读卡时，电子标签直接接触壳体，如果使用这样的读卡方式，由于天线的响应频段对于直接接触的介质十分敏感，常常会出现电子标签安置于一些物体表面无法识别的问题，对于射频识别读写器而言，电子标签与读写器直接接触，会导致电子标签的响应频段的偏移，而读写器发射的射频信号频段是按照原响应频段设计的，不能跟随电子标签的频段偏移而偏移，因此会造成读写困难的问题。由于本发明设置了射频标签读写平台，因此使得电子刷卡时与平台表面接触，而不会与读写装置承载主体内的天线直接接触，大大降低了电子标签的响应频段偏移，该平台的设置十分巧妙，在不过多增加制造成本的情况下，即可解决上述的问题。Most of the existing radio frequency identification reading and writing devices are equipped with antennas in the casing. When reading the card, the electronic tag directly contacts the casing. There will be a problem that the electronic tag is placed on the surface of some objects and cannot be recognized. For the radio frequency identification reader, the direct contact between the electronic tag and the reader will cause the shift of the response frequency band of the electronic tag, and the radio frequency emitted by the reader The signal frequency band is designed according to the original response frequency band, and cannot follow the frequency band offset of the electronic tag, so it will cause difficulties in reading and writing. Since the radio frequency tag reading and writing platform is set in the present invention, the electronic card is swiped in contact with the surface of the platform without directly contacting the antenna in the main body of the reading and writing device, which greatly reduces the response frequency band offset of the electronic tag. The arrangement is very ingenious, and the above-mentioned problems can be solved without increasing the manufacturing cost too much.
限位托台3包括横向限位部31，该横向限位部31对应于电子标签的两宽边，电子标签沿平行于其长边的方向移动时，横向限位部31对电子标签进行限位，且横向限位部31分别设置于电子标签的两侧。The limiting pallet 3 includes a lateral limiting portion 31, which corresponds to the two wide sides of the electronic tag. When the electronic tag moves in a direction parallel to its long side, the lateral limiting portion 31 limits the electronic tag. Position, and the lateral limit portion 31 is respectively provided on both sides of the electronic tag.
限位托台3还包括纵向限位部32，该纵向限位部32对应于电子标签的两长边，电子标签沿平行于其宽边的方向移动时，纵向限位部32对电子标签进行限位，且纵向限位部32分别设置于电子标签的两侧。The limiting pallet 3 also includes a longitudinal limiting portion 32, which corresponds to the two long sides of the electronic tag, and when the electronic tag moves in a direction parallel to its broad side, the longitudinal limiting portion 32 will move the electronic tag. limit, and the longitudinal limit parts 32 are respectively arranged on both sides of the electronic tag.
横向限位部31和纵向限位部32在图1中是一体式设置的，便于安装和制造，实际上如果有需要的话，横向限位部31和纵向限位部32也可以是相互分开的。较佳地，限位托台3与射频标签读写平台2可以为可拆式连接，比如射频标签读写平台的表面可以具有平行于电子标签长边和平行于电子标签宽边的凹槽，横向限位部31和纵向限位部32插设于该凹槽内，且横向限位部31和纵向限位部32可以沿着凹槽滑动，从而适合于不同大小的电子标签，通用性更广。The transverse limiting portion 31 and the longitudinal limiting portion 32 are integrated in FIG. 1 , which is convenient for installation and manufacture. In fact, if necessary, the transverse limiting portion 31 and the longitudinal limiting portion 32 can also be separated from each other. . Preferably, the limit bracket 3 and the radio frequency tag reading and writing platform 2 can be detachably connected, such as the surface of the radio frequency label reading and writing platform can have a groove parallel to the long side of the electronic tag and parallel to the wide side of the electronic tag, The horizontal limiting part 31 and the vertical limiting part 32 are inserted in the groove, and the horizontal limiting part 31 and the longitudinal limiting part 32 can slide along the groove, so that they are suitable for electronic tags of different sizes, and the versatility is more wide.
本实施例中，限位托台3设置于电子标签的四个直角处，具体可参阅附图，射频标签读写平台2的上表面还固定设置有易取支撑部4，易取支撑部4突出于射频标签读写平台2的上表面，电子标签通过易取支撑部4与射频标签读写平台2的上表面相隔开。易取支撑部4的作用不同于射频标签读写平台2的作用，由于电子标签一般为薄片型，类似于普通银行卡的形状和大小，且电子标签表面光滑，进行电子标签的读取时，电子标签贴合于射频标签读写平台后难以取下，尤其是在射频标签读写平台2为水平放置的情况下，实际上由于本发明设置了该易取支撑部4即可解决上述的问题，而无需改变电子标签的结构或形状。In the present embodiment, the limit bracket 3 is arranged at the four right angles of the electronic tag. For details, please refer to the accompanying drawings. Protruding from the upper surface of the radio frequency tag reading and writing platform 2 , the electronic tag is separated from the upper surface of the radio frequency label reading and writing platform 2 by the easy-to-take support part 4 . The effect of the easy-to-take support part 4 is different from that of the radio frequency tag reading and writing platform 2. Since the electronic tag is generally thin, similar to the shape and size of an ordinary bank card, and the surface of the electronic tag is smooth, when the electronic tag is read, It is difficult to take off the electronic tag after it is attached to the radio frequency tag reading and writing platform, especially when the radio frequency label reading and writing platform 2 is placed horizontally, in fact, the above-mentioned problems can be solved by setting the easy-to-take support part 4 in the present invention , without changing the structure or shape of the electronic tag.
易取支撑部4可以为一体设置，该易取支撑部设置于射频标签读写平台2的中心部位，具体可参阅图2，易取支撑部4也可以为分体式设置，具体请参阅图1，各个限位托台3分别与易取支撑部4连接，易取支撑部4支撑电子标签的四个直角处。The easy-to-take support part 4 can be set as a whole, and the easy-to-take support part is arranged at the center of the radio frequency tag reading and writing platform 2. For details, please refer to FIG. 2. The easy-to-take support part 4 can also be set in a split type. , each limit bracket 3 is respectively connected with the easy-to-take support part 4, and the easy-to-take support part 4 supports the four right angles of the electronic tag.
分别位于电子标签两侧的横向限位部31的间距大于等于电子标签的长度；分别位于电子标签两侧的纵向限位部32的间距大于等于电子标签的宽度。两横向限位部31的距离略大于实际电子标签的长度可以便于使用者的使用，进一步减少刷卡时间。The distance between the transverse limiting parts 31 on both sides of the electronic tag is greater than or equal to the length of the electronic tag; the distance between the vertical limiting parts 32 on both sides of the electronic tag is greater than or equal to the width of the electronic tag. The distance between the two transverse limiting parts 31 is slightly longer than the length of the actual electronic tag, which can facilitate the use of the user and further reduce the time for swiping the card.
