[0002] With the continuous updating and iteration of battery technology, there are many ways to insulate the surface of the battery shell after the battery cell is welded into the shell. However, for the surface insulation treatment of cylindrical steel shell batteries, the main methods are to cover PET blue film, glue filling, cleaning and oiling. This insulation treatment method is difficult to deal with the problem of shell surface corrosion. For this reason, UV inkjet printing insulation treatment technology is proposed to solve the problem that the surface treatment of cylindrical steel shell batteries is difficult to deal with shell surface corrosion. In the UV inkjet printing process, the battery cell is clamped by a clamping and rotating mechanism and driven to rotate, and the spraying mechanism sprays the battery cell. The battery cell rotation speed, nozzle speed, ink output, etc. directly affect the uniformity of the UV film thickness on the cylindrical surface of the cylindrical battery. Among them, the rotation speed of the cylindrical battery cell is particularly critical.

[0003] However, in the current battery cell spraying process, when the cylindrical battery cell is loaded into the clamping and rotating mechanism, the battery cell is prone to eccentricity. Once eccentricity occurs, the linear speed of the battery cell surface fluctuates when the battery cell rotates, resulting in uneven spraying thickness. Utility Model Content

Through the above structural arrangement, the cylindrical battery cell 1 is coaxially placed between the fixed pad 6 and the fixed washer 11, and the cylinder 13 extends to drive the moving plate 4 close to the fixed plate 3, so that the fixed pad 6 and the fixed washer 11 clamp the two ends of the cylindrical battery cell 1, and then the rotating motor 10 starts to drive the active wheel 7 to rotate, thereby driving the active rotating shaft 5 to rotate through the belt 9 and the driven wheel 8, thereby driving the cylindrical battery cell 1 to rotate, and at the same time, the fixed washer 11 rotates synchronously with the cylindrical battery cell 1. In this embodiment, the fixed pads 6 and the fixed pads 6 are both adapted to the ends of the cylindrical battery cell 1 to ensure that the cylindrical battery cell 1 can be clamped.
