[0026] See Figures 1-2As shown, the FPCA product pre-compression testing mechanism described in this embodiment includes a module cavity 1, a pre-compression component 2, a horizontal push-pull structure 3, and a vertical pull structure 4. The module cavity 1 is used to place the product to be tested. The pre-compression component 2 is rotatably disposed in the module cavity 1 and located above the module cavity 1. The horizontal push-pull structure 3 is connected to the pre-compression component 2 and is used to push and pull to adjust the position of the pre-compression component 2 relative to the module cavity 1. The vertical pull structure 4 is connected to the pre-compression component 2 and is used to vertically pull to adjust the position of the pre-compression component 2 relative to the module cavity 1.

[0027] This embodiment has a simple structure and reasonable design. By setting it as a split pre-compression test mechanism, the relative position of the pre-compression component to the module cavity 1 can be adjusted through the horizontal push-pull structure 3 and the vertical pull structure 4 during testing, so as to achieve automatic pre-compression closure and ensure that the product is flat and stable in the test cavity during testing.

[0028] Specifically, through the cooperation of the horizontal push-pull structure 3 and the vertical pull structure 4, when they move synchronously, the position and angle of the pre-compression component 2 relative to the module cavity 1 are adjusted. When one of them does not move, the pre-compression component 2 is pre-compression closed, thereby flexibly adjusting the pre-compression angle and clamping degree, and performing automatic pre-compression closure.

[0029] In some embodiments, the pre-compression component 2 includes a pre-compression plate 21, a pre-compression disc 22, and a linkage bearing 23. The pre-compression plate 21 is movably disposed in the module cavity 1. The pre-compression disc 22 is engaged with the pre-compression plate 21 and connected to the vertical pull structure 4. The linkage bearing 23 is disposed in the module cavity 1 and connected to the pre-compression plate 21.

[0030] Specifically, the pre-pressure plate 21 is composed of an integrally formed horizontal pre-pressure block and a vertical pre-pressure block. The horizontal pre-pressure block is located directly above the module cavity 1, and the horizontal pre-pressure block is connected to the pre-pressure disc 22 and the linkage bearing 23 respectively. The vertical pre-pressure block is connected to the horizontal push-pull structure 3.

[0031] Specifically, the preload plate 21 is rotatably connected to the linkage bearing 23 via a rotating shaft structure 24.

[0032] This embodiment specifically shows the structural configuration of the pre-compression component 2. Through the arrangement of the pre-compression plate 21, the pre-compression disc 22 and the linkage bearing 23, it can achieve a cooperative connection with the module cavity 1, the horizontal push-pull structure 3 and the vertical pull structure 4, thereby achieving stable pre-compression and preventing loosening.

[0033] In some embodiments, the linkage bearing 23 is screwed into the module cavity 1.

[0034] Specifically, the module cavity 1 is provided with a transition plate 11, and the pre-compression component 2 is connected to the transition plate 11.

[0035] In this embodiment, the linkage bearing 23 can be screwed onto the adapter plate 11, thereby realizing the angle adjustment of the pre-compression component 2 relative to the module cavity 1 during the pre-compression process, and achieving better pre-compression closure.

[0036] In some embodiments, the horizontal push-pull structure 3 is configured as a cylinder horizontal push-pull structure 3, and the vertical pull structure 4 is configured as a cylinder vertical pull structure 4.

[0037] In this embodiment, a cylinder structure is used for lateral and vertical push-pull, which is simple in structure, stable in operation, and easy to control, thereby facilitating better pre-compression during the pre-compression testing process.

[0038] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
