The fitting assembly 23 is used to drive the pressing plate assembly 22 to move along the guide rail 21 in a direction close to the mounting base 1 to crimp a circuit board and the display panel.

[0031] In the technical solution of the present invention, since the provided crimping jig includes a mounting base 1 and a crimping mechanism 2; the mounting base 1 is used to place the display panel; the crimping mechanism 2 includes a guide rail 21 arranged on the mounting base 1, a pressing plate assembly 22 arranged on the guide rail 21, and a fitting assembly 23 arranged on the mounting base 1 and the pressing plate assembly 22. The fitting assembly 23 is used to drive the pressing plate assembly 22 to move along the guide rail 21 towards the direction close to the mounting base 1, so as to crimp the circuit board and the display panel. That is, the display panel can be placed on the mounting base 1, the circuit board is placed above the display panel, and the pins of the circuit board are aligned with the pins on the display panel. Then, the fitting assembly 23 drives the pressing plate assembly 22 to move along the guide rail 21 towards the direction close to the mounting base 1 to crimp the circuit board and the display panel, thereby reducing the thickness of the entire crimping jig, being able to replace the bulky crimping jig, and meeting the requirements of various detection instruments, improving the versatility of the crimping jig. It should be particularly noted that the thickness of the crimping jig provided by the present invention is thinner than that of all the crimping jigs on the current market.

[0032] In one embodiment, refer to Figure 1 、 Figure 2 and Figure 4 Figure [reference numbers not provided in the original], the fitting assembly 23 includes a first magnetic member 231 arranged on the mounting base 1 and a second magnetic member 232 arranged on the pressing plate assembly 22. The first magnetic member 231 and the second magnetic member 232 are arranged opposite to each other, and the first magnetic member 231 and the second magnetic member 232 cooperate to fit the pressing plate assembly 22 and the mounting base 1. Further, a first receiving groove is formed on one side of the mounting base 1 facing the pressing plate assembly 22, and the first magnetic member 231 is placed in the first receiving groove. A second receiving groove is formed on one side of the pressing plate assembly 22 facing the mounting base 1, and the second magnetic member 232 is placed in the second receiving groove. Both the first magnetic member 231 and the second magnetic member 232 can be magnets. That is, through the magnetic force between the first magnetic member 231 and the second magnetic member 232, the pressing plate assembly 22 can be driven to move along the guide rail 21 towards the direction close to the mounting base 1. Finally, due to the magnetic force of the first magnetic member 231 and the second magnetic member 232, one end of the pressing plate assembly 22 can be firmly attached to the mounting base 1, and the other end of the pressing plate assembly 22 can crimp the circuit board and the display panel. At the same time, the number of both the first magnetic member 231 and the second magnetic member 232 can be multiple.

[0033] In one embodiment, refer to Figure 1 and Figure 4, the crimping mechanism 2 further includes a clamping plate 24 disposed below the pressing plate assembly 22. A third magnetic member 25 is provided on the side of the pressing plate assembly 22 facing the clamping plate 24. The third magnetic member 25 is used to cooperate with the clamping plate 24 to clamp the circuit board between the third magnetic member 25 and the clamping plate 24. A third receiving groove is formed on the side of the pressing plate assembly 22 facing the clamping plate 24. The third magnetic member 25 is placed in the third receiving groove. The third magnetic member 25 can be a magnet, and the clamping plate 24 can be a ferromagnetic metal plate. Thus, the circuit board can be clamped between the third magnetic member 25 and the clamping plate 24 through the magnetic action of the third magnetic member 25 on the clamping plate 24, so as to fix the circuit board on the crimping mechanism 2.

[0034] Specifically, a positioning pin 26 is provided on the side of the pressing plate assembly 22 facing the clamping plate 24. A first positioning hole (not shown) that cooperates with the positioning pin 26 is formed on the clamping plate 24. The positioning pin 26 is used to sequentially pass through the second positioning hole on the circuit board and the first positioning hole on the clamping plate 24 to position the circuit board and the clamping plate 24. That is, the second positioning hole on the circuit board is provided corresponding to the positioning pin 26 on the pressing plate assembly 22, and the positioning pin 26 sequentially passes through the second positioning hole on the circuit board and the first positioning hole on the clamping plate 24, so that the circuit board can be positioned. In addition, the number of the positioning pins 26 can be multiple. A plurality of first positioning holes that cooperate with the plurality of positioning pins 26 are formed on the clamping plate 24, and a plurality of second positioning holes that cooperate with the plurality of positioning pins 26 are also formed on the circuit board.

[0035] In an embodiment, referring to Figure 1 , Figure 3 and Figure 4 , the pressing plate assembly 22 includes a sliding frame 221 that is liftably disposed on the guide rail 21, a pressing head 222 disposed on the sliding frame 221, and a rubber strip 223 disposed on the pressing head 222.

A first threaded hole 230 is formed in the sliding horizontal plate 228, and a second threaded hole corresponding to the first threaded hole 230 is formed in the pressing head 222. Thus, the sliding frame 221 and the pressing head 222 can be connected by a threaded fastener. In the present invention, the number of the guide rails 21 and the sliders 229 can be four groups or more than four groups. Thus, through the cooperation of multiple groups of the guide rails 21 and the sliders 229, the stability of the lifting movement of the sliding frame 221 can be ensured.

[0037] Further, the pressing head 222 includes a connecting portion 224 disposed on the sliding frame 221 and a pressing portion 225 extending from the connecting portion 224 toward the mounting base 1. A clamping groove 226 for accommodating the rubber strip 223 is formed in the pressing portion 225. Since the rubber strip 223 has elasticity, the rubber strip 223 can be directly clamped in the clamping groove 226 or taken out of the clamping groove 226, which is beneficial to the disassembly and assembly of the rubber strip 223.

[0038] In an embodiment, referring to Figure 1 and Figure 2 , the mounting base 1 includes a bottom plate 11 and a mounting frame 12 disposed on one side of the bottom plate 11.

The second connecting plate 122 is disposed at a relatively spaced interval from the bottom plate 11. The guide rail 21 is disposed on the side of the second connecting plate 122 facing the bottom plate 11. The bottom plate 11 is used for placing the display panel. That is, the pressing plate assembly 22 can be disposed in the space surrounded by the mounting frame 12 through the guide rail 21 to further reduce the thickness of the pressing jig. When the pressing plate assembly 22 is lifted to the highest position along the guide rail 21, the height of the pressing plate assembly 22 from the bottom plate 11 can be 3.75 mm. At this time, the height of the entire pressing jig does not exceed 20 mm.

[0039] In addition, the pressing jig further includes a reference plate 3 disposed on the bottom plate 11. The reference plate 3 is used to determine the placement position of the display panel. For display panels of different sizes, corresponding scribing of the placement positions is performed on the reference plate 3 to ensure that display panels of different sizes can be accurately docked with the circuit board. Of course, the reference plate 3 can be made of a transparent material.

[0040] In one embodiment, the bottom plate 11 is provided with an installation through hole 13, and a transparent plate (not shown) is embedded in the installation through hole 13. The transparent plate is used to observe whether the display panel and the circuit board are aligned. That is, from below the bottom plate 11, it can be observed through the transparent plate whether the pins of the display panel and the pins of the circuit board are aligned. The transparent plate can be a quartz glass plate. Of course, this is not limited thereto in the present invention, and other suitable transparent plates are also possible.

[0041] In addition, the present invention also provides a detection device. Among them, the detection device includes a detection system and the crimping jig as described above. The detection system is used to connect to the circuit board. Since the detection device adopts all the technical solutions of the above embodiment, it at least has all the beneficial effects brought by the technical solutions of the above embodiment, which will not be elaborated here one by one.

[0042] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly.
