At the same time, a plurality of corner light sources 209 are installed outside the detection box 203. When the end face detection camera 204 takes pictures, the plurality of corner light sources 209 always irradiate and fill light the shooting part, so as to facilitate the end face detection camera 204 to take pictures of the end face of the pole piece.

[0030] Specifically disclosed, the mobile unit 1 includes a slide rail 101, a slider 102, and a drive motor 103.

The drive motor 103 is fixedly connected to the outer side of the slide rail 101. A screw rod threadedly connected to the slider 102 is rotatably arranged inside the slide rail 101, and the drive end of the drive motor 103 is in transmission connection with the screw rod.

[0031] Specifically disclosed, through holes, namely a pole piece end face detection port 206 and a pole piece bottom detection port 207, are formed on the outer side of the detection box 203, and the pole piece end face detection port 206 is located between a plurality of corner light sources 209.

[0032] Since the pole piece end face detection port 206 is located between a plurality of corner light sources 209, the plurality of corner light sources 209 can accurately irradiate and fill light to the shooting part.

[0033] Specifically disclosed, a reflecting mirror 208 is fixedly installed inside the detection box 203, and the reflecting mirror 208 is located on the side of the lens end of the bottom detection camera 205 and directly below the pole piece bottom detection port 207.
