The connecting rod 408 is moved by the electric push rod 407, so that the guide column 412 can be adjusted synchronously with the connecting rod 408. The guide column 412 increases the movement stability of the connecting rod 408 and improves the accuracy of the test rod 410 in testing the mechanical strength of solar cells, thereby improving the testing efficiency.

[0030] Further explanation, the up and down moving parts include a guide frame 4, a cylinder b401, a driving rod 402, a guide rod 403, two movable sleeves 404 and a support base 405; the guide frame 4 is installed on the connecting frame 3, the guide frame 4 is installed with a cylinder b401, and the cylinder b401 drives the installation of the driving rod 402; the guide rod 403 is installed on the guide frame 4; the two movable sleeves 404 are respectively installed on the driving rod 402 and the guide rod 403, and the two movable sleeves 404 are installed on one side of the support base 405. When the driving rod 402 moves up and down, the movable sleeves 404 on the periphery of the driving rod 402 move synchronously. The two movable sleeves 404 are connected to the support base 405, so that the two movable sleeves 404 can move at the same time, and the movable sleeves 404 on the periphery of the guide rod 403 move synchronously along the periphery of the guide rod 403, which is convenient for increasing the stability of the up and down movement of the driving rod 402 and improving the use of the up and down moving parts.

[0035] Further explanation: The mounting components include a support rod 2, a clamping block 201, a mounting frame 202, and a connecting plate 203. The support rod 2 is mounted on the base 1. The support rod 2 is equipped with a clamping block 201, which is then equipped with a mounting frame 202. The mounting frame 202 is then equipped with a connecting plate 203, which is then equipped with a guide groove. The support rod 2 supports the clamping block 201 on the base 1. One side of the clamping block 201 is shaped like a "U," and is mounted to the mounting frame 202. Four sets of fixing components are provided, and two pairs are mounted opposite each other on either side of the base 1. This allows for the mobile clamping and fixing of solar cells undergoing mechanical strength testing, increasing test accuracy.

The driving rod 402 is connected to the support base 405 through the movable sleeve 404. The support base 405 is installed with bolts and the connecting base 406, so that the connecting base 406 can synchronize the left and right moving parts to drive the rod 402 up and down to move the test frame 409 downward until the solar cell breaks, so as to detect the ultimate breaking force and the ultimate deformation of the cell, and use these two data to characterize the mechanical properties of the cell.

[0039] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
