Description

Technical Field

[0001] The utility model relates to the technical field of electric measuring frames, in particular to an electric measuring frame for solving the problem of false pressing of capacitance value affected by OGS. Background Art

[0002] At present, most in-vehicle touch screens use OGS products. Since the OGS products are coated with an OGS functional layer on the back of the glass cover plate to make the glass have touch function. In order to improve efficiency, large pieces of glass are first used to make the whole surface induction layer, then the whole surface is screen-printed with double-sided blue film, and finally small pieces are cut by CNC. Before binding the FPC, the OGS products will first perform electrical measurement on the glass with the OGS functional layer of a single grain to reduce material waste caused by functional problems after binding. However, the electromagnetic fields in contact with any object on the side of the OGS functional layer with the blue film are different, which will cause the capacitance value data of the OGS product to be too large, making the electric measuring frame determine that the OGS product is defective and affecting the production efficiency of the product.

Detailed implementation manners

[0022] To facilitate the understanding of the present utility model, the present utility model will be described more comprehensively below with reference to the relevant drawings.

[0023] An electrical measurement rack for solving the false pressure of capacitance affected by OGS, referring to Figure 1 , includes an electrical measurement rack body 10, an OGS touch screen 20 is placed on the electrical measurement rack body 10, and a pressing device 30 for detecting the function of the OGS touch screen 20 is provided on the electrical measurement rack body 10. The pressing device 30 is used to press and fix the FPC 40 of the OGS touch screen 20 for electrical measurement.

[0024] Referring to Figure 2 , the OGS touch screen 20 includes a glass cover plate 21 and an OGS functional layer 22 plated on one side of the glass cover plate 21. An FPC 40 for testing is bound on the OGS functional layer 22. When the OGS functional layer 22 is placed upward, the pressing device 30 presses downward to fix the FPC 40. Since the FPC 40 is located on one side of the OGS functional layer 22, during the pressing process of the pressing device 30 on the FPC 40, the OGS functional layer 22 will affect the false pressure of capacitance, resulting in inaccurate test results. Therefore, a glass groove 11 for placing the OGS touch screen 20 is provided on the electrical measurement rack body 10. The size of the glass groove 11 is adapted to the size of the glass cover plate 21, and the glass cover plate 21 is placed in the glass groove 11. A clearance groove 12 is opened at the position of the electrical measurement rack body 10 relative to the OGS functional layer 22. The clearance groove 12 is communicated with the glass groove 11, and the clearance groove 12 is located at the middle position of the glass groove 11. The side of the OGS touch screen 20 with the OGS functional layer 22 faces downward and is placed in the glass groove 11, so that the OGS functional layer 22 is placed in the clearance groove 12.

[0025] Furthermore, referring to Figure 1 , the depth of the clearance groove 12 is greater than the thickness of the OGS functional layer 22. After the OGS functional layer 22 is placed in the clearance groove 12, the OGS functional layer 22 does not contact the bottom of the clearance groove 12, so as to avoid the OGS functional layer 22 contacting any object, thereby avoiding the pressing damage caused by the contact of the OGS functional layer 22.

[0026] Referring toFigure 2 , a binding position 221 for binding the FPC 40 is provided on the OGS functional layer 22. The binding position 221 of the OGS functional layer 22 is arranged towards the side close to the lamination device 30. One end of the FPC 40 is bound to the binding position 221 of the OGS functional layer 22, and the other end of the FPC 40 is located directly below the lamination device 30.

[0027] Further, referring to Figure 3 , the binding position 221 of the OGS functional layer 22 is placed downward in the glass groove 11. A silica gel groove 13 is provided at the position of the electro - test rack body 10 relative to the binding position 221. The silica gel groove 13 is opened along the length direction of the binding position 221, and the silica gel groove 13 communicates with the clearance groove 12. A height - increasing silica gel 131 is placed in the silica gel groove 13. The height - increasing silica gel 131 is used to increase the height of the FPC 40 so that the FPC 40 can be normally bound to the binding position 221 of the OGS functional layer 22. By increasing the height of the FPC 40 with the height - increasing silica gel 131, the FPC 40 is horizontally placed on the upper surface of the electro - test rack body 10. One end of the FPC 40 is bound to the binding position 221, and the other end of the FPC 40 extends towards the side close to the lamination device 30 and extends below the lamination device 30.

[0028] Referring to Figure 3 , the lamination device 30 is arranged to be horizontally movable. The lamination device 30 can be moved directly above the FPC 40. The end of the FPC 40 far from being bound to the binding position 221 is an interface pin end 41. The lamination device 30 includes a lamination sheet 31. The lamination sheet 31 is used to press downward onto the interface pin end 41 of the FPC 40 for electrical testing. A metal wiring piece is fixed on the lower surface of the lamination sheet 31, and a wiring terminal is formed on the metal wiring piece. The wiring terminal is used to connect with the interface pins of the FPC 40.

[0029] Further, referring to Figure 3 , a lamination silica gel 32 is provided on one side of the lamination sheet 31. The lamination silica gel 32 is arranged along the length direction of the lamination sheet 31. When the lamination sheet 31 is pressed downward to the interface pin end 41 of the FPC 40, the lamination silica gel 32 is synchronously pressed downward to laminate the binding position 221 of the OGS functional layer 22 to fix the connection between the FPC 40 and the OGS functional layer 22 and prevent the FPC 40 from disconnecting during electrical testing.

[0030] By providing the clearance groove 12 that clears the OGS functional layer 22, the problem of too large capacitance data caused by the OGS functional layer 22 contacting an object is avoided. And the silica gel groove 13 in the clearance groove 12 accommodates the height - increasing silica gel 131 for increasing the height of the FPC 40, without interfering with the normal binding of the FPC 40 and the OGS functional layer 22 and the electrical testing of the FPC 40, thus making the electrical test results accurate, reducing the defective rate, and improving the production efficiency.

[0031] 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 modifications and improvements can still be made, and these all fall within the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
