[0025] See also Figure 1-5 A false pressure jig that is easy to observe the deviation includes a jig table 1 and a test board 4. A product placement groove 2 is provided on one side of the top of the jig table 1. The side of the product placement groove 2 close to the false pressure component 3 is open, and the product placement groove 2 is a stepped groove body. The product placement groove 2 is used to place the product and can position and stabilize the product.

[0026] See also Figure 3-4 In this embodiment, a guide slider 1001 is integrally formed on one side of the LED light strip 10, and a limit slider 1002 is integrally formed on the top and bottom of the guide slider 1001; the inner top wall and the inner bottom wall of the guide slide groove 901 are both provided with a limit slide groove 902, and the LED light strip 10 is slidably connected in the guide slide groove 901 through the guide slider 1001, and the limit slider 1002 is placed in the limit slide groove 902; a layer of damping rubber sheet is provided on the inner walls of the guide slide groove 901 and the limit slide groove 902, and a groove is also provided on the side of the LED light strip 10 away from the guide slider 1001.
[0027] Specifically, by designing the guide slider 1001, the limiting slider 1002, the guide slot 901 and the limiting slot 902, the LED light strip 10 can be conveniently installed or removed in a pulling manner, and the stability of the LED light strip 10 on the false pressure head 9 is ensured, and the guide slot 901 and the limiting slot 902 are designed with a damping structure, which improves the damping of the LED light strip 10 when it is therein, improves the position stability of the LED light strip 10 therein, and avoids sliding. A groove is also provided on the back of the LED light strip 10, which is convenient for the staff to insert their fingers and pull out the LED light strip 10 from the false pressure head 9.
[0028] See also Figure 3 In this embodiment, a limit stopper 903 is fixed at the bottom of one side of the false pressure head 9 and close to the guide groove 901 , and the bottom of the limit stopper 903 is flush with the bottom of the false pressure head 9 .
[0029] Specifically, the designed limit block 903 can limit the distance that the LED light strip 10 extends into the guide groove 901, so that one end of the LED light strip 10 can be against the limit block 903, and the other end can be flush with the side of the false pressure head 9 to ensure aesthetics. The bottom of the limit block 903 is flush with the bottom of the false pressure head 9, which ensures the flatness of the bottom of the false pressure head 9 and avoids instability during pressing caused by the protrusion of the limit block 903.
[0030] See also Figure 1-2 In this embodiment, the support frame 6 is fixed to the fixture table 1 by bolts, one side of the support plate 8 is connected to the inner side of the support frame 6 by a torsion spring shaft, and one side of the pressing handle 7 is fixed to the support plate 8.
[0031] Specifically, the support frame 6 is installed by bolts, which is convenient for subsequent disassembly and maintenance, and the support plate 8 can be pressed at the connection between the FPC 5 and the sensor glass by the restoring force generated by the torsion spring shaft, thereby ensuring the stability after the connection, and the designed pressing handle 7 makes it convenient to use the pressing handle 7 to lift the entire fake pressure head 9.
[0032] See also Figure 2 In this embodiment, the top of the dummy pressure head 9 is movably connected to the support plate 8, and the dummy pressure head 9 is designed in an L shape.
[0033] Specifically, the connection method between the dummy pressure head 9 and the support plate 8 can be a bolt connection, so that the longitudinal position of the dummy pressure head 9 can be conveniently adjusted to adapt to different test conditions. The dummy pressure head 9 is designed to be L-shaped, which can reduce the weight of the dummy pressure head 9 on the one hand, and facilitate the installation and disassembly of the LED light strip 10 on the other hand.
[0034] See also Figure 2In this embodiment, the LED light strip 10 is connected to the mains via a wire, and the bottom of the LED light strip 10 is a light emitting area and is flush with the bottom of the dummy pressure head 9 .
[0035] Specifically, the bottom of the LED light strip 10 is flush with the bottom of the dummy pressing head 9, which can avoid the situation where the bottom of the dummy pressing head 9 is not flat enough and the pressing is unstable, thereby facilitating the use of the light-emitting area at the bottom of the LED light strip 10 to illuminate the entire dummy pressing area.
[0036] See also Figure 1 In this embodiment, the test board 4 is placed on the top of the fixture table 1 and below the support plate 8 , and the side of the FPC 5 away from the test board 4 is located directly below the dummy pressure head 9 .
[0037] Specifically, one side of FPC5 is movably connected to the test board 4, which can facilitate the subsequent replacement of FPC5. The other side of FPC5 is located directly below the fake pressure head 9, which is more conducive to aligning the PIN pin of FPC5 with the interface end of the sensor glass, thereby facilitating the fake pressure action.
[0038] When in use, the staff can place the product to be tested in the product placement slot 2, and make the sensor glass interface end located on the side close to the dummy pressure head 9, and then turn on the LED light bar 10. The LED light bar 10 can illuminate the area below the dummy pressure head 9, thereby illuminating the PIN pin position of the FPC5. Then the staff can press down the pressing handle 7. By pressing down one end of the pressing handle 7, one end of the dummy pressure head 9 can be tilted, which is convenient for the staff to align the PIN pin of the FPC5 with the interface end of the sensor glass. When position deviation occurs, the staff can correct the position of the FPC5 in time, so that the PIN pin of the FPC5 is aligned with the interface end of the sensor glass. After alignment, the staff can release the downward pressure on the pressing handle 7, and the dummy pressure head 9 is affected by the reset of the torsion spring shaft, thereby generating downward pressure and pressing it tightly at the connection between the FPC5 and the sensor glass, thereby ensuring the stability of the connection.
