[0037] The working principle of the present utility model is as follows:

[0038] In specific operation, manual loading is performed: the product (battery cell) is first placed on the longitudinal clamping fixture, then the product is driven by the Y-axis sliding plate to pass through the laser range finder for distance measurement, and then the top printing gantry assembly performs spraying and pre-curing on the product, followed by final curing. The aforementioned longitudinal clamping fixture can operate on the large surface and two narrow surfaces of the product. After the final curing of the aforementioned four surfaces is completed, the operator places the product on the transverse clamping fixture, and the side printhead performs spraying and final curing on the sides of the product (i.e., the two small end surfaces of the battery cell).

[0039] The present utility model can also adapt to prismatic battery cells, realize six-surface UV printing of the battery cell, and the sliding table carries the product to complete UV printing, pre-curing and final curing.

[0040] This technology allows for the rapid and precise application of insulating layers to aluminum-cased battery cells, replacing the traditional blue film coating process. After UV printing, pre-curing and final curing lamps are used to solidify the coating. The equipment investment is small, and the withstand voltage parameters of the printed insulating layer are far higher than those of conventional blue film. The insulating coating meets the requirements for fast charging on high-voltage platforms. The UV-printed coating has high strength, is not easily damaged, has high insulation safety, and can effectively improve printing efficiency.

[0042] In the description of this application, it should be noted that the terms "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0043] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or vertical, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0044] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly.
