Abstract
Description
Technical Field
[0001] This application relates to the technical field of auxiliary equipment for thin film switch production, and particularly to a jig for attaching shrapnel of a thin film switch. Background Art
[0002] A thin film switch is an operating system integrating button functions, indicating elements, and instrument panels, and is widely used in fields such as electronic communication, electronic measurement instruments, industrial control, and medical equipment.
[0003] In the prior art, a thin film switch generally uses shrapnel to control the contact and separation of the upper and lower contact blocks. Specifically, when a user presses it, the shrapnel will deform and at the same time the upper contact block will be pressed down to abut against the lower contact block. Subsequently, after the external force is removed, the shrapnel will reset and drive the upper contact block away from the lower contact block. Therefore, during the production process of the thin film switch, attaching the shrapnel is one of the processes. Generally, there is glue at the placement position of the shrapnel. Therefore, the staff only needs to place the shrapnel at the corresponding position and then enter the next process. Currently, many attachments of the shrapnel of the thin film switch still use manual attachment, and it is necessary to manually pick up the shrapnel one by one and place it at the corresponding positions, resulting in low efficiency. When there are many positions, problems such as misplacement and omission may occur. Summary of the Utility Model
[0004] The purpose of this application is to provide a jig for attaching shrapnel of a thin film switch to solve at least one of the above technical problems.
[0005] To solve the above technical problems, this application provides a jig for attaching shrapnel of a thin film switch, including a pressure plate and a blocking member;
[0006] A limiting groove adapted to the outer shape of the product is formed at the bottom of the pressure plate, and a plurality of first through holes are formed in the pressure plate along its thickness direction, and the positions of the first through holes correspond to the shrapnel assembly positions of the product;
[0007] A second through hole is formed horizontally on one side of the pressure plate, and the first through hole is communicated with the second through hole; the blocking member includes a plug rod adapted to the second through hole and suitable for inserting into the second through hole and a first connecting rod connecting a plurality of the plug rods;
[0008] In the above implementation process, the blocking member and the pressure plate are in a spliced state in the initial state. In this state, the insertion rod is inserted into and passes through the second through hole. The insertion rod intervenes in the second through hole. At this time, the staff can assemble multiple elastic pieces into the first through hole at one time. The elastic pieces will stay in the first through hole due to the blocking of the insertion rod. Subsequently, the staff lifts the pressure plate and places the product in the limiting groove below the pressure plate. The limiting groove positions and aligns the product so that the hole positions of the first through hole are exactly located at the positions where the elastic pieces need to be assembled. Subsequently, by controlling the first connecting rod to extract the insertion rod, after the insertion rod disengages from the first through hole, the elastic pieces fall under the action of gravity and are placed at the corresponding positions for elastic piece assembly. In this way, the assembly of multiple elastic pieces can be completed at one time. In this solution, through the cooperation of the pressure plate and the blocking member, the staff can load multiple elastic pieces at one time. With the positioning function of the limiting groove, the first through hole can exactly align with the corresponding assembly positions of the elastic pieces. Subsequently, further in cooperation with the extraction of the blocking member, multiple elastic pieces can be quickly placed on the product. Compared with the traditional method of gradually assembling single pieces, the bonding fixture provided by this solution can quickly complete the assembly of elastic pieces, thereby improving the assembly efficiency and work efficiency.
[0009] Preferably, it further includes a pressing plate module; the pressing plate module includes a pressing rod adapted to the first through hole and a second connecting rod connecting multiple pressing rods.
[0010] In the above implementation process, this solution further sets that the pressing plate module can abut against the upper end of the elastic piece. After the blocking member is extracted, the pressing rod acting on the elastic piece can cause the elastic piece to fall vertically, better landing on the corresponding position of the product. At the same time, with the certain gravity of the pressing plate module itself, the elastic piece can be better attached to the colloid at the corresponding position on the product, achieving stable attachment. And the staff can also press down to a certain extent to make the elastic piece fit more stably on the product.
[0011] Preferably, an arc chamfer is formed on the end face of the pressing rod close to the first through hole.
[0012] In the above implementation process, the arc chamfer formed on the end of the pressing rod can improve the smoothness when the pressing rod penetrates into the first through hole, thereby improving the convenience of use.
[0013] Preferably, a buffer gasket is provided on the end face of the pressing rod close to the first through hole.
[0014] In the above implementation process, this solution further sets a buffer gasket at the end of the pressing rod, which can achieve a certain buffering effect when the pressing rod contacts the elastic piece.
[0015] Preferably, a first handle is provided on the second connecting rod.
[0016] Preferably, a second handle is provided on the first connecting rod.
[0017] Preferably, third handles are oppositely arranged on both sides of the pressure plate;
[0018] In the above implementation process, in this solution, by setting the first handle, it is convenient for the staff to control the tablet pressing module. By setting the second handle, it is convenient for the staff to control the blocking member. By setting the third handle, it is convenient for the tooling staff to move the pressure plate.
[0019] Preferably, an arc chamfer is formed at the end of the insertion rod;
[0020] In the above implementation process, the arc chamfer formed at the end of the insertion rod can improve the smoothness of inserting the insertion rod into the second through hole, and thus facilitate the staff to better insert the insertion rod into the second through hole.
[0021] Preferably, the aperture of the first through hole is 0.1 mm larger than the diameter of the elastic piece;
[0022] In the above implementation process, by reasonably designing the aperture of the first through hole, it is possible to ensure both sufficient assembly accuracy of the elastic piece and sufficient material discharging smoothness.
[0023] Compared with the prior art, the beneficial effect of this application lies in that: in this solution, through the cooperation of the pressure plate and the blocking member, the staff can load multiple elastic pieces at one time. With the positioning function of the limiting groove, the first through hole can just be aligned with the corresponding assembly position of the elastic piece. Subsequently, further cooperating with the extraction of the blocking member, multiple elastic pieces can be quickly placed on the product; compared with the traditional method of gradually assembling single pieces, the fitting jig provided by this solution can quickly complete the assembly of the elastic pieces, thereby improving the assembly efficiency and work efficiency.

[0035] Embodiment
[0036] In the prior art, a membrane switch generally uses a shrapnel to control the contact and separation of the upper and lower contact blocks. Specifically, when the user presses it, it will drive the shrapnel to deform and at the same time make the upper contact block press down and abut against the lower contact block. Subsequently, after the external force is removed, the shrapnel will reset and drive the upper contact block away from the lower contact block. Therefore, in the production process of the membrane switch, shrapnel fitting is one of the processes. There is generally glue at the placement position of the shrapnel. Therefore, the staff only needs to place the shrapnel at the corresponding position, and then enter the next process after placing the shrapnel. At present, many shrapnel fittings of membrane switches still use manual fitting, and it is necessary to manually pick up the shrapnel one by one and place it at the corresponding positions, with low efficiency.
