[0033] Among them, the frame 10 includes a mounting seat 11, a roller assembly 12 provided on the mounting seat 11, and a rubber coating roller assembly 13 for wrapping the cell 200 to be wrapped. The cell 200 to be wrapped moves along a first direction on the roller assembly 12.

[0034] Further, the mounting seat 11 includes a back plate 111 and two support plates 112 spaced apart from each other on one side of the back plate 111. The roller assembly 12 is provided inside the support plates 112, and the blocking mechanism 20 is provided outside the support plates 112.

[0035] In some embodiments, one roller assembly 12 is provided and is disposed between two support plates 112. In other embodiments, two roller assemblies 12 are provided and are disposed corresponding to the support plates 112, that is, one roller assembly 12 is respectively disposed on the inner sides of the two support plates 112, and a gap is formed between the two roller assemblies 12.

[0036] In some embodiments, one blocking mechanism 20 is provided and is disposed on the outer side of any one of the support plates 112. In other embodiments, two blocking mechanisms 20 are provided and are disposed corresponding to the support plates 112, that is, one blocking mechanism 20 is respectively disposed on the outer sides of the two support plates 112.

[0037] In this embodiment, an example is given where two roller assemblies 12 are provided and are disposed corresponding to the support plates 112, and one blocking mechanism 20 is provided and is disposed on the outer side of any one of the support plates 112 for illustration.

[0038] Further, please refer to Figures 1-3 , the blocking mechanism 20 includes: a support base 21, a driving assembly 22, and a blocking block 23. The support base 21 is disposed on the outer side of the support plate 112, the driving assembly 22 is disposed on the support base 21, the blocking block 23 is connected to the driving assembly 22, and the driving assembly 22 drives the blocking block 23 to perform an extending or retracting movement in the second direction to fix or release the battery cell 200 to be coated with film. Wherein, the first direction and the second direction are perpendicular to each other. Exemplarily, taking the back plate 111 as a reference object, the first direction may be the front-back direction, and the second direction may be the left-right direction.

[0039] In this embodiment, please refer to Figure 1 , when the battery cell 200 to be coated with film rotates to the post-coating position for film laminating and fitting, the driving assembly 22 drives the blocking block 23 to extend to fix the battery cell 200 to be coated with film, preventing it from rolling backward due to the rotation of the lower roller assembly 12, so that the blue film can be closely attached to the side of the battery cell during post-coating, thereby reducing defects such as side bubbles and wrinkles, reducing rework, and thus improving the film coating yield and efficiency of the battery cell. After film laminating and fitting, the driving assembly 22 drives the blocking block 23 to retract to release the battery cell, without hindering the downward rotation of the battery cell. When the film coating method of the battery cell coating device is changed, the blocking mechanism can be synchronously removed or installed. For example, when changing from U-shaped film coating to ring-shaped film coating, the blocking mechanism 20 can be conveniently and quickly removed; when changing from ring-shaped film coating to U-shaped film coating, the blocking mechanism 20 can be conveniently and quickly installed, thereby realizing compatibility between U-shaped film coating and ring-shaped film coating.
