The battery cell placing table is used for supporting and fixing the battery cell 9, and the battery cell 9 is prevented from moving in the process of rolling the compression roller 2 to influence the film coating effect.

The film pressing devices can be provided with a plurality of groups, each group of film pressing devices are arranged on one side of the corner part 903 of the battery cell 9 needing film coating at intervals, and the film pressing materials 10 are rolled and pressed simultaneously. Illustratively, the lamination devices in fig. 9 are two sets.

Referring to fig. 9 and 10, the cell placing table may include a machine table 1101 and a clamping arm 1102, where the clamping arm 1102 is disposed on the machine table 1101, and the clamping arm 1102 is configured to clamp the cell 9 to the machine table 1101, so as to prevent the cell 9 from sliding due to the acting force of the pressing roller 2.

The coating equipment can comprise a cell moving device, and the cell moving device is used for transferring the cell 9 to which the coating material 10 is required to be attached to the corner and the second surface 902 to a cell placing table. The battery cell moving device can be a mechanical arm which can clamp the battery cell to the battery cell and place the battery cell, or the battery cell moving device can also be a conveying belt which can convey the battery cell to the battery cell and place the battery cell, and the battery cell 9 is transferred to the battery cell and placed the battery cell by the mechanical arm.

The coating equipment may include a film sticking device, configured to stick the film material 10 to the first surface 901, where the moving device sends the battery cell 9 with the first surface 901 stuck with the film material 10 to the battery cell 9 placing table, and the film pressing device sticks the film material 10 to the corner portion 903 of the battery cell 9 and the second surface 902 on the battery cell 9 placing table.

The above description is only a preferred embodiment of the present application and is not intended to limit 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.
