Description

Silver paste is brittle after curing and is easily deformed by external force and open circuit occurs. The attachment of film is completely manual operation, and the accuracy and effect of alignment attachment are relatively poor. The attachment process will also cause the silver paste routing of the membrane button to bend and crack, resulting in poor function open circuit.

[0004] Therefore, in order to improve the production efficiency of membrane keypad assembly and reduce the functional open circuit defects caused by assembly, we specifically designed an Incell membrane keypad assembly fixture. Utility Model Content

The downward pressure rod 10 is designed with an arc chamfer to avoid the membrane key main body wiring being broken due to a too small bending angle, and also to avoid assembly interference on the client side causing an open circuit due to a too large bending angle; a horizontal vacuum adsorption hole 6 is opened in the inner cavity of the fixture body 1 and at a position corresponding to the positioning groove 401, and a vertical vacuum adsorption hole 5 is opened in the inner cavity of the fixture body 1 and at a position corresponding to the membrane key positioning groove 4.

[0031] See also Figure 2-3 In the present embodiment, the membrane key body includes a membrane key portion 11, a bending portion 12 and a connecting portion 13. The bending portion 12 is connected to the membrane key portion 11, and the connecting portion 13 is connected to the bending portion 12. The membrane key portion 11 is placed in the membrane key positioning groove 4, and the bending portion 12 is placed in the clamping groove 401; the size and shape of the membrane key portion 11 are adapted to the size and shape of the membrane key positioning groove 4, and the width of the bending portion 12 is adapted to the width of the clamping groove 401; the surface of the membrane key portion 11 is adhered with foam glue 14, the surface of the connecting portion 13 is adhered with foam glue 2 15, and the surfaces of the foam glue 14 and the foam glue 2 15 are both provided with release films.

[0032] Specifically, when manufacturing the fixture body 1, the size and shape of the membrane button positioning groove 4 can be designed according to the size and shape of the membrane button part 11. Similarly, the size and shape of the positioning groove 401 can also be designed according to the size and shape of the bending part 12, which can enhance the flexibility of the scheme. The foam glue 14 and the foam glue 2 15 need to be pre-glued to the membrane button part 11 and the connecting part 13 before assembly, and the release film of the unused surface of the foam glue 14 and the foam glue 2 15 should be retained to facilitate the subsequent tearing of the release film and use of the foam glue 14 and the foam glue 2 15 to stick together with the cover plate body 16 and the display module body 17.

[0033] See also Figure 2-4 In this embodiment, grooves 7 are provided on both sides of the clamp body 1 to facilitate the insertion of the fixing rod 9 when it is pressed down, and the width of the groove 7 is greater than the width of the fixing rod 9.

[0034] Specifically, the setting of the groove 7 facilitates the rotation of the rotating rod 8 for pressing, and the two sides of the fixed rod 9 can enter the two grooves 7 respectively, so that the lower pressing rod 10 can normally contact the bending part 12 and bend the bending part 12 90 degrees.

[0035] See also Figure 1 , Figure 4 Figure 5 and Figure 6 In this embodiment, a plurality of vertical vacuum adsorption holes 5 are provided, and the plurality of vertical vacuum adsorption holes 5 are evenly distributed on the inner bottom wall of the membrane button positioning groove 4, a plurality of horizontal vacuum adsorption holes 6 are provided, and the plurality of horizontal vacuum adsorption holes 6 are evenly distributed on the side wall of the module positioning groove 3 and close to the position below the positioning groove 401; the vertical vacuum adsorption holes 5 and the horizontal vacuum adsorption holes 6 are respectively connected to an external vacuum pump through pipes.

[0036] Specifically, through the designed vertical vacuum adsorption hole 5, it is possible to utilize the connection with the vacuum pump to adsorb the membrane button part 11 in the membrane button positioning groove 4 through the effect of exhaust, thereby ensuring the stability of the membrane button part 11, and the horizontal vacuum adsorption hole 6 can also utilize the connection with the vacuum pump to adsorb the bending part 12 through the effect of exhaust after the bending part 12 is bent 90 degrees, thereby ensuring the stability of the bending part 12.

[0037] See also Figure 6-7 In this embodiment, it also includes a cover body 16 and a display module body 17. The display module body 17 is installed on one side of the cover body 16. The size of the display module body 17 is adapted to the size of the module positioning groove 3, and the size of the cover body 16 is adapted to the size of the cover positioning groove 2; a connector 1701 is provided on the display module body 17, and a plug-in end is provided at one end of the connecting part 13 away from the membrane button part 11, and the plug-in end is adapted to the connector 1701.

[0038] Specifically, the membrane key part 11 and the connecting part 13 are respectively pasted to the cover body 16 and the display module body 17. When pasting, it is necessary to ensure that the part with the foam glue keeps the membrane in a non-arched state. When the membrane key body has a length margin, it can be Figure 7 The position shown is arched (i.e., the leftmost position of the top of the display module body 17). If it does not exist, they can be closed together normally.

[0039] During use: the staff first places the membrane button part 11 in the membrane button positioning groove 4 (the side without foam glue 14 and foam glue 2 15 faces downward), and makes the bending part 12 enter the positioning groove 401. At this time, the external vacuum pump can be started (the vacuum pump is a common air extraction device in the prior art, so it is not shown in the figure in this application). The vacuum pump works to make the vertical vacuum adsorption hole 5 generate adsorption force, so as to achieve the effect of adsorbing and fixing the membrane button part 11. Then, the fixing rod 9 is turned over. The fixing rod 9 is rotated by the rotating rod 8, thereby driving the pressing rod 10 to turn over. Since the position of the pressing rod 10 corresponds to the bending part 12, the pressing rod 10 will slowly squeeze the bending part 12 when pressing down, thereby pressing the bending part 12 into Figure 5 In the state shown, one side of the bent portion 12 is attached to the inner wall of the module positioning groove 3 having the horizontal vacuum adsorption hole 6. The bent portion 12 can be firmly adsorbed by the vacuum pump. At this time, since the membrane keypad portion 11 and the bent portion 12 are respectively adsorbed stably by the vertical vacuum adsorption hole 5 and the horizontal vacuum adsorption hole 6, the stability of the entire membrane keypad body on the fixture body 1 can be ensured:

[0040] Then tear off the release film of foam glue 14 on the membrane button part 11 and the release film of foam glue 2 15 on the connecting part 13, and buckle the cover body 16 and the display module body 17 in the fixture body 1, so that the cover body 16 enters the cover positioning groove 2, and the display module body 17 enters the module positioning groove 3. Then stop the vacuum pump and take out the cover body 16 and the display module body 17 from the fixture body 1. At this time, the entire membrane button body can be taken out of the fixture body 1 through the adhesion of foam glue 14 and foam glue 2. Finally, plug the connector on the connecting part 13 into the connector 1701 of the display module body 17, and smooth the film from the connector 1701 end to both sides of the display module body 17 to complete the whole process and realize the assembly of the membrane button body and the display module body 17.
