[0002] With the increasing use of flexible panels, the market demand for crimping testing of panel cell products is increasing, and the corresponding crimping testing devices are gradually moving towards mass production. The pressure head structure is a key component in the crimping testing device.

[0003] At present, before the panel is made into a module, it is necessary to carry out a cell product point screen test, that is, to check whether the product is qualified before attaching the FPC. Specifically, the pressure head and the clamp are connected by bolts, and the FPC is clamped between the pressure head and the clamp. The pressure head is moved down so that the FPC gold finger presses down to connect the PAD point of the cell product to light up the screen.

[0004] Since the types of cell products to be tested are different, different FPCs need to be replaced according to the products to be tested. The existing pressure head structure cannot be used with different FPCs. Therefore, when replacing the FPC, the pressure head structure needs to be replaced, which is complicated and reduces the detection efficiency. Utility Model Content

[0022] As a further preference, a second positioning pin and a connecting member are further provided on the connecting plate.

[0023] By adopting the above technical solution, the indenter structure can be accurately and stably connected to the testing device for use.

[0024] The present application also provides a testing device applicable to different cell products, including a frame body and the above indenter structure, and the indenter structure is detachably connected to the frame body.

[0034] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0035] The present application discloses an indenter structure applicable to different cell products. Refer to Figures 1-4, A collet structure applicable to different cell products includes a connecting plate 1 and a collet assembly 2; in practical applications, the collet assembly 2 is connected to a testing device through the connecting plate 1. The connecting plate 1 is connected to the testing device, and the collet assembly 2 is connected to the bottom of the connecting plate 1. A number of connectors 13 are provided on the connecting plate 1 for connecting to the testing device. In this embodiment, the connectors 13 are screws. To improve the installation accuracy of the connecting plate 1, two grooves are opened on the upper surface of the connecting plate 1, and a second positioning pin 12 is inserted into each of the two grooves; among them, the collet assembly 2 includes a collet body 21, a pressing plate 22, a clamping plate 23, and an FPC 24 for conducting the cell product. Specifically, the collet body 21 is fixedly connected to the connecting plate 1 by screws. To improve the connection accuracy between the collet assembly 2 and the connecting plate 1, two first positioning pins 26 are provided between the collet body 21 and the connecting plate 1. Positioning grooves 11 for inserting the first positioning pins 26 are opened on both the collet body 21 and the connecting plate 1; when the testing device moves the collet assembly 2 downward, the collet body 21 presses the FPC 24 to connect with the panel cell product 3, and the gold fingers on the FPC 24 contact the gold fingers of the panel cell product 3 to achieve signal conduction and light up the screen body.

[0036] In this embodiment, the pressing plate 22 is connected to the bottom of the collet body 21, and the clamping plate 23 is connected to the bottom of the pressing plate 22 to clamp the FPC 24. The collet body 21 and the pressing plate 22 can slide relative to each other to adjust the relative position between the collet body 21 and the FPC 24. After replacing the FPC 24, by sliding the collet body 21, the relative position between it and the FPC 24 is changed. When the collet structure moves downward, the collet body 21 can press the replaced FPC 24 to connect it with the corresponding panel cell product 3, so that the collet structure of the present application can be applicable to different FPC 24; specifically, the collet body 21 and the pressing plate 22 are connected by a bolt 25. An adjustment slot hole 211 extending along the width direction of the collet body 21 is opened on the collet body 21. The threaded end of the bolt 25 passes through the adjustment slot hole 211 and is threadedly connected to the pressing plate 22. When the collet body 21 moves, the bolt 25 can move in the adjustment slot hole 211. After the collet body 21 moves to a suitable position, the bolt 25 is rotated to fix the position between the collet body 21 and the pressing plate 22. Since the collet body 21 and the pressing plate 22 are in relative motion, it can also be understood that when the pressing plate 22 moves, the bolt 25 can move in the adjustment slot hole 211; to improve the stability of the movement of the collet body 21, a guiding pin 212 is fixedly connected to the bottom of the collet body 21, and a guiding slot 221 for inserting the guiding pin 212 is opened on the pressing plate 22. The opening direction of the guiding slot 221 is the same as the opening direction of the adjustment slot hole 211. When the collet body 21 moves, the guiding pin 212 slides in the guiding slot 221, making the movement of the collet body 21 more stable.

[0037] To further improve the crimping effect of the indenter body 21, a pressing portion 213 that is integrally formed on one side of the indenter body 21 and bends downward and is located above the FPC 24 is provided for crimping the FPC 24 and the panel cell product 3. The width of the pressing portion 213 gradually narrows from top to bottom, so that the pressing portion 213 can accurately press the gold fingers of the FPC 24, realizing the connection of the gold fingers of the FPC 24 and the panel cell product 3 and achieving signal conduction. Further, a buffer strip 214 is fixedly connected to the bottom of the pressing portion 213. In this embodiment, the buffer strip 214 is a silicone strip, and the buffer strip 214 can play a buffering effect to avoid damage caused by excessive pressure when the gold fingers of the FPC 24 are connected to the gold fingers of the panel cell product 3.

[0038] To facilitate the replacement of the FPC 24, a magnetic member 222 for adsorbing the clamping plate 23 is fixedly connected to the bottom of the pressing plate 22. In this embodiment, the magnetic member 222 uses an annular magnet, and the clamping plate 23 is a metal member. The magnetic member 222 adsorbs the clamping plate 23 to realize the fixation of the FPC 24, which is convenient to operate and can improve the replacement efficiency of the FPC 24. Further, a plurality of fixing columns 223 are fixedly connected to the bottom of the pressing plate 22, and through holes 241 for the fixing columns 223 to pass through are formed on both the FPC 24 and the clamping plate 23, making the installation positions of the FPC 24 and the clamping plate 23 more accurate.

[0039] Refer to Figure 5 As shown, the present application also discloses a testing device applicable to different cell products, including a frame body 4 and the above indenter structure. The indenter structure is detachably connected to the frame body 4. Specifically, the connecting plate 1 is fixedly connected to the testing device through a connecting member 13. The panel cell product 3 is placed on the frame body 4, and the panel cell product 3 is detected by moving the indenter structure downward.
