背景技术Background technique

一般常见的现有一种键盘的结构，其具有一铝或钢等金属材质的支撑用底板，该底板底面必须贴附一背胶膜，以构成一键盘半成品提供后续与电路板组装等制作工艺使用，而且目前一般业者均是采用人手配合目测的方式将背胶膜贴合于底板上，贴合时必须留意二者定位问题，因人手黏贴产生歪斜也会使得黏胶层外漏于底板外，不仅不美观，且容易沾黏灰尘等杂物，再者，因背胶膜的厚度极薄，对于长宽尺寸可达30公分×11公分的大型底板而言，所相对应的背胶膜尺寸也相对增加，不仅黏附困难度提高，不易对准、容易歪斜，或造成绉折、气泡，且当剥离该背胶膜的离形纸后，人手不易抓持，常不慎碰触黏胶层影响黏度及其洁净度。Generally, there is a common keyboard structure, which has a support base plate made of metal such as aluminum or steel, and a back adhesive film must be attached to the bottom surface of the base plate to form a semi-finished keyboard for subsequent use in manufacturing processes such as circuit board assembly. , and at present, the general industry is to stick the adhesive film on the bottom plate by manual and visual inspection. When pasting, you must pay attention to the positioning of the two. The skew caused by manual sticking will also cause the adhesive layer to leak outside the bottom plate. , not only unsightly, but also easy to stick to dust and other sundries. Furthermore, because the thickness of the adhesive film is extremely thin, for a large base plate with a length and width of 30 cm × 11 cm, the corresponding adhesive film The size is relatively increased, not only the difficulty of adhesion is increased, it is difficult to align, it is easy to be skewed, or it may cause creases and air bubbles, and when the release paper of the adhesive film is peeled off, it is difficult for human hands to grasp and often accidentally touch the adhesive. The layer affects the viscosity and its cleanliness.

请参阅图1所示，本实用新型提供的组装治具20，具有一治具平台21，在该治具平台21上设有多个定位柱22，该多个定位柱22通过一升降机构23控制可同步作垂直于该治具平台21的升降移动，该治具平台21的大小是依组装构件的尺寸而定，以略大于组装构件的尺寸为宜，该定位柱22所设置的位置以及数量，也因组装构件尺寸不同而异，以图1所示构件，其依序包括一背胶膜43、一底板41，该类构件结构常见于计算机、移动电话，或个人数字助理(PDA)的键盘结构，该背胶膜43具有黏胶层(图中未示出)用以与底板41黏贴，该背胶膜43及该底板41的相对应位置均设有定位孔431、411，该定位柱22则相对应该定位孔431、411的位置设置于该治具平台21上。Please refer to Fig. 1, theassembly jig 20 provided by the utility model has ajig platform 21 on which a plurality ofpositioning columns 22 are arranged, and the plurality ofpositioning columns 22 pass through alifting mechanism 23 Control can synchronously move up and down perpendicular to thejig platform 21. The size of thejig platform 21 depends on the size of the assembled components, preferably slightly larger than the size of the assembled components. The position of thepositioning column 22 and The quantity also varies due to the size of the assembled components. The components shown in FIG. 1 include a backadhesive film 43 and abottom plate 41 in sequence. This type of component structure is commonly found in computers, mobile phones, or personal digital assistants (PDAs) The keyboard structure, theadhesive film 43 has an adhesive layer (not shown in the figure) for sticking to thebottom plate 41, the corresponding positions of theadhesive film 43 and thebottom plate 41 are provided withpositioning holes 431, 411, The positioning posts 22 are disposed on thejig platform 21 corresponding to the positions of the positioning holes 431 , 411 .

有关该升降机构23控制该多个定位柱22同步垂直升降移动的方式，请参阅图2及图3所示，在该治具平台21内部设有一连动件211，该多个定位柱22的底部穿透该治具平台21设置于该连动件211上，该连动件211配置于多个弹簧212上，通过该多个弹簧212的弹性，可提供该连动件211于一释放位置P1以及一按压位置P2之间弹性往复运动，也可采用弹片或其它具有弹性的弹性元件取代该弹簧212，至于该释放位置P1及按压位置P2的设定，依构件的厚度、定位柱22的长度等等因素而设定，其设定的原则在于，当该连动件211下降至按压位置P2时，可使定位柱22同步下沉，且其下沉的深度是以易于取出该底板41及该背胶膜43为原则，同时，可于该连动件211底部设置限位块213，用以界定该按压位置P2，亦即该定位柱22下沉的深度，至于该释放位置P1则可使得当该弹簧212使该连动件211弹至释放位置P1时，该定位柱22凸伸于该治具平台21上，且其凸伸的高度H至少可满足将所有构件(如图1所示的背胶膜43、底板41)套入即可。Regarding the manner in which the elevatingmechanism 23 controls the synchronous vertical lifting movement of the plurality ofpositioning columns 22, please refer to FIGS. The bottom penetrates thejig platform 21 and is arranged on thelinkage 211. Thelinkage 211 is arranged on a plurality ofsprings 212. Through the elasticity of thesprings 212, thelinkage 211 can be provided in a release position. Elastic reciprocating movement between P1 and a pressing position P2, thespring 212 can also be replaced by shrapnel or other elastic elastic elements. Length and other factors are set, and the principle of setting is that when thelinkage 211 descends to the pressing position P2, thepositioning column 22 can be sunk synchronously, and the depth of its sunk is so that it is easy to take out thebottom plate 41 And theadhesive film 43 is the principle. At the same time, alimit block 213 can be set at the bottom of thelinkage 211 to define the pressing position P2, that is, the sinking depth of thepositioning column 22. As for the release position P1 It can be made that when thespring 212 makes thelinkage 211 bounce to the release position P1, thepositioning column 22 protrudes on thejig platform 21, and the height H of its protruding can at least satisfy all components (as shown in FIG. 1 Shownadhesive backing film 43, bottom plate 41) are inserted and get final product.

如图2所示，当该连动件211未受力时，该连动件211是自然位于该释放位置P1，定位柱22凸伸于该治具平台21上，此时，可依序将该背胶膜43、底板41套入定位柱22，当然，该背胶膜43具有黏胶层的面是朝向上方，将该背胶膜43套设于该定位柱22后，该背胶膜43可自然落于该治具平台21上，再将底板41套上后，底板41可自然落于该背胶膜43上，而后再适度施压于该底板41上，使该底板41与该背胶膜43二者确实黏合，而后如图3所示，当该连动件211下降至按压位置P2时，该多个定位柱22可同步下沉于该治具平台21下，此时可将已黏合的底板41与背胶膜43取出该治具平台21，而后再释放该连动件211，使该连动件211自动上升至释放位置P1，使该多个定位柱22再度凸伸于该治具平台21上，即可进行下一键盘的组装。As shown in Figure 2, when thelinkage 211 is not stressed, thelinkage 211 is naturally located at the release position P1, and thepositioning column 22 protrudes from thejig platform 21. At this time, the Theadhesive film 43 and thebottom plate 41 are inserted into thepositioning column 22. Of course, theadhesive film 43 has an adhesive layer facing upwards. After theadhesive film 43 is sleeved on thepositioning column 22, theadhesive film 43 can naturally fall on thejig platform 21, and then put thebottom plate 41 on, thebottom plate 41 can naturally fall on theback adhesive film 43, and then moderately apply pressure on thebottom plate 41 to make thebottom plate 41 and thebottom plate 41 Theadhesive film 43 and the two are indeed bonded, and then as shown in Figure 3, when thelink 211 is lowered to the pressing position P2, the plurality ofpositioning columns 22 can sink under thejig platform 21 synchronously, and at this time Take out the gluedbottom plate 41 and backadhesive film 43 from thejig platform 21, and then release thelinkage 211, so that thelinkage 211 automatically rises to the release position P1, so that the plurality ofpositioning columns 22 protrude again On thejig platform 21 , the next keyboard can be assembled.

有关前述该升降机构23控制定位柱22升降的方式属于纯机械式，除此之外，该升降机构也可为一控制电路(图中未示出)且电连接该定位柱22，而该控制电路可连动于气压装置、液压装置或油压装置等驱动装置，用以驱动该多个定位柱22升降，此属于现有技术，在此不予赘述。The manner in which thelifting mechanism 23 controls the lifting of thepositioning column 22 is purely mechanical. In addition, the lifting mechanism can also be a control circuit (not shown in the figure) and is electrically connected to thepositioning column 22, and the control The electric circuit can be linked with a driving device such as a pneumatic device, a hydraulic device or an oil pressure device to drive the plurality ofpositioning columns 22 up and down, which belongs to the prior art and will not be repeated here.

根据以上结构，可归纳本实用新型提供的组装治具20的组装方法如图4所示，包括下列步骤：According to the above structure, it can be concluded that the assembly method of theassembly jig 20 provided by the present invention is shown in Figure 4, including the following steps:

释放该升降机构，使定位柱上升并凸伸于该治具平台上Release the lifting mechanism, so that the positioning column rises and protrudes on the fixture platform
