Description

Technical Field

[0001] The utility model relates to the technical field of touch screens, in particular to a false pressing fixture that is easy to replace the FPC. Background Art

[0002] In the touch screen manufacturing industry, before binding the FPC to the touch screen, a functional test is performed on the sensor glass of the touch screen to ensure that the touch screen before binding the FPC is normal. Therefore, a false pressing test needs to be carried out before the touch screen is bound to the FPC. The false pressing test is to first perform alignment and pressing of the false pressing FPC in the false pressing fixture before binding the touch screen, so that the false pressing gold fingers on the false pressing FPC form an electrical connection with the corresponding binding gold fingers on the touch screen, to simulate the environment of binding the touch screen to the FPC, and then send a test signal to the touch screen through the false pressing FPC to test whether the various functions of the touch screen are normal.

[0003] However, during the false pressing test, the false pressing FPC on the false pressing fixture is reused. As the number of false pressing times increases, the false pressing FPC on the false pressing fixture will be worn, so it needs to be replaced regularly. When replacing the false pressing FPC, it is necessary to remove the false pressing FPC and then re-align and replace it with a new false pressing FPC, which takes a long time and has low replacement efficiency.

Detailed implementation manners

[0023] To facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the relevant attached drawings.

[0024] A false pressing fixture for easily replacing an FPC, referring to Figure 1 and Figure 2 , includes a false pressing fixture 10, and a replaceable supporting block 20 is provided on the false pressing fixture 10. A false pressing FPC 30 is fixed on the supporting block 20. When it is necessary to replace the false pressing FPC 30, the supporting block 20 can be disassembled and a new supporting block 20 can be replaced onto the false pressing fixture 10.

[0025] Referring to Figure 1 and Figure 3 , a fixing groove 11 is formed on the false pressing fixture 10, the supporting block 20 is accommodated in the fixing groove 11, one side of the fixing groove 11 is open, and the opening of the fixing groove 11 is communicated with the outside. The false pressing fixture 10 can be slid out of the false pressing fixture 10 through the opening of the fixing groove 11 for replacement. The position of the false pressing FPC 30 on the supporting block 20 is fixed. When the supporting block 20 is completely accommodated in the fixing groove 11, the false pressing FPC 30 is located at the specified binding position, and there is no need to calibrate multiple times.

[0026] Furthermore, referring to Figure 1, a screen accommodation groove 12 for accommodating the touch screen is provided on the dummy pressing fixture 10. The screen accommodation groove 12 is located on one side of the fixing groove 11. One side of the screen accommodation groove 12 is communicated with the fixing groove 11. The screen accommodation groove 12 is used to accommodate the touch screen and limit the position of the touch screen. When the touch screen is accommodated in the screen accommodation groove 12, the dummy pressing FPC 30 on the supporting block 20 corresponds to the position bound to the touch screen, so as to facilitate binding.

[0027] Further, referring to Figure 3 , the depth of the fixing groove 11 is greater than the depth of the screen accommodation groove 12, and the height of the supporting block 20 is the same as the depth of the fixing groove 11. The dummy pressing FPC 30 is fixed to the top of the supporting block 20. The dummy pressing FPC 30 is vertically placed with respect to the supporting block 20. One end of the dummy pressing FPC 30 for binding to the touch screen is the binding end 31. The binding end 31 of the dummy pressing FPC 30 is located on the side facing the screen accommodation groove 12, so that the binding end 31 of the dummy pressing FPC 30 can be bound to the touch screen.

[0028] Further, referring to Figure 2 , a double-sided adhesive 40 for fixing to the bottom of the fixing groove 11 is provided at the bottom of the supporting block 20. When it is necessary to replace the new dummy pressing FPC 30, the supporting block 20 is removed and a new supporting block 20 is replaced. The new supporting block 20 is pasted to the bottom of the fixing groove 11 to fix the position of the supporting block 20, thereby limiting the position of the dummy pressing FPC 30.

[0029] Referring to Figure 1 and Figure 3 , a pressing component for pressing the dummy pressing FPC 30 is provided on the dummy pressing fixture 10. The pressing component includes a hinged portion 50 fixed to the dummy pressing fixture 10, a connecting portion 60 connected to the hinged portion 50, and a pressing block 70 connected to the connecting portion 60. The hinged portion 50 is fixed to one side of the dummy pressing FPC 30. The connecting portion 60 is hinged to the hinged portion 50. The connecting portion 60 can rotate around the hinged portion 50. The pressing block 70 is fixed to the end of the connecting portion 60 away from the hinged portion 50. The pressing block 70 can rotate under the drive of the connecting portion 60 to rotate to press the upper surface of the dummy pressing FPC 30.

[0030] Further, referring to Figure 3 , the connecting portion 60 is arranged in parallel with the placement position of the dummy pressing FPC 30. The position where the pressing block 70 presses on the dummy pressing FPC 30 is on one side of the binding end 31 of the dummy pressing FPC 30. The pressing block 70 is used to fix the position of the dummy pressing FPC 30 and does not prevent the dummy pressing FPC 30 from being bound to the touch screen, so as not to shift during binding and testing.

[0031] Further, referring to Figure 2 and Figure 3, one end of the dummy press FPC30 away from the bonding end 31 is the interface pin end 32. The interface pin end 32 is used to connect to an external power supply so that the dummy press FPC30 can send a test signal to the touch screen to test whether the various functions of the touch screen are normal. An energizing part 80 is provided on the interface pin end 32 of the dummy press FPC30. The energizing part 80 is vertically arranged with respect to the placement position of the dummy press FPC30. The energizing part 80 is pressed onto the interface pin end 32 of the dummy press FPC30 and is connected to the interface pin end 32 of the dummy press FPC30 to energize the dummy press FPC30.

[0032] By providing a replaceable supporting block 20 in the dummy press fixture 10, and the position of the dummy press FPC30 on the supporting block 20 is fixed. When the dummy press FPC30 is worn and needs to be replaced, a new supporting block 20 is replaced onto the dummy press fixture 10, and the position of the dummy press FPC30 corresponds to the bonding position of the touch screen. Then, it is not necessary to calibrate the position of the dummy press FPC30 multiple times for alignment, which reduces the time for replacing the dummy press FPC30 and has a high efficiency in replacing the dummy press FPC30.

[0033] The above-described embodiments merely represent several implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
