[0036] A connecting plate 80 is mounted on the Z-direction drive component 70. The connecting plate 80 is used to fix the first camera assembly 90, the supplementary lighting assembly 100, and the second camera assembly 200. The connecting plate 80 is provided with multiple fixing holes 81, which are arranged vertically. The fixing holes 81 are used to fix the supplementary lighting assembly 100. By using the fixing holes 81 arranged vertically, the installation position of the supplementary lighting assembly 100 can be adjusted when it is installed in different positions of the fixing holes 81.

[0037] The first camera assembly 90 includes a first mounting plate 91 and a first camera body 92. One end of the first mounting plate 91 is fixed to the top of the connecting plate 80, and the first camera body 92 is fixed to the other end of the first mounting plate 91.

The third plate body 221 has a mounting hole 2210 and an arc groove 2211. The mounting hole 2210 is rotatably connected to the third mounting plate 210, and the arc groove 2211 is locked to the third mounting plate 210. Different locking positions of the arc groove 2211 and the third mounting plate 210 result in different mounting angles for the fourth mounting plate 220. The second camera body 230 is fixed to the fourth plate body 222. At this time, the second camera body 230 is tilted, and the extension line of the second camera body 230 and the extension line of the first camera body 92 form an acute angle. The intersection of the extension line of the second camera body 230 and the extension line of the first camera body 92 is the position of the battery cell terminal.

[0040] When using the cell module testing device, the cell module is located on the conveyor line 12. The X-direction drive unit 30, the Y-direction drive unit 50, and the Z-direction drive unit 70 drive the connecting plate 80, the first camera assembly 90, the supplementary lighting assembly 100, and the second camera assembly 200 to move. When the first camera assembly 90, the supplementary lighting assembly 100, and the second camera assembly 200 move above the cell module, the first camera assembly 90 and the second camera assembly 200 respectively acquire images. The image acquired by the first camera assembly 90 is used to obtain the position information of the electrode post, and the image acquired by the second camera assembly 200 is used to identify whether the positive and negative electrode directions of the cell are correct.

[0041] Through the above design, the batteries in conveyor line 12 can be addressed and polarity detected in one go, eliminating the need for handling between multiple devices or moving along the assembly line. Addressing and polarity detection are completed in one step, improving production efficiency and reducing costs. The connection line between the first camera assembly 90 and the second camera assembly 200 is perpendicular to conveyor line 12, and the first camera assembly 90 and the second camera assembly 200 work simultaneously, further improving efficiency.

[0042] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model.
