The inspection camera 300 can take a picture of the battery piece 600 and sample the same, and determine whether the battery piece 600 has defects. The detecting cabinet 310 can protect the detecting camera 300, so that the detecting camera 300 is not easy to collide with the outside to cause damage, and other equipment can be arranged in the detecting cabinet 310 to better improve the photographing and identifying capabilities of the detecting camera 300. The detection light source 320 in this embodiment can supplement light to the battery cell 600 to be photographed, thereby improving the photographing and identification capabilities of the detection camera 300.

In this embodiment, the fixed end of the turning arm 100 is provided with a first rotating shaft 110; the turning arm 100 is divided into two sections, which are sequentially divided into a first section turning arm 120 and a second section turning arm 130 from the fixed end to the installation end, and the first section turning arm 120 and the second section turning arm 130 are rotatably connected by a second rotating shaft 140 (see fig. 2).

The overturning arm 100 can rotate around the first rotating shaft 110 to realize the transportation of the battery piece 600. Meanwhile, the turnover arm 100 is divided into two sections, so that the flexibility of the turnover arm 100 can be improved, and the cell can be conveniently conveyed. In other embodiments, invert arm 100 can be further divided into multiple segments, so long as the flexibility of invert arm 100 is increased.

In this embodiment, the surface of the backlight panel 200 away from the mounting end is provided with a suction cup 210, the surface close to the mounting end is provided with an adapter rod 230, and the backlight panel 200 can be rotatably connected with the turnover arm 100 through the adapter rod 230.

The suction cup 210 can fix the battery piece 600 carried on the backlight plate, so that the battery piece 600 does not shake or even fall off. When the backlight board 200 carries the battery piece 600 to move to the position right below the detection camera 300 along with the installation end, the battery piece 600 can be adjusted to different angles to allow the detection camera 300 to take pictures and sample for data analysis because the battery piece can be rotatably connected through the adapter rod 230, so that whether the battery piece 600 has defects or not can be better judged. And before the sample is taken a picture to detection camera 300, the board 200 that is shaded can adjust to vertical decurrent state, and the piece on battery piece 600 surface can receive the action of gravity and drop this moment, but battery piece 600 can not drop owing to be adsorbed by sucking disc 210, can detach the piece like this to avoid causing the interference to subsequent sample of taking a picture.

The rotary AOI equipment and the transmission detection device are not only limited to the detection of the front and back films of the battery piece, but also are suitable for the detection device of the finished battery.

The above description is only an example of the present application and is not intended to limit the scope of the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
