[0021] Reference Figures 1-4 This embodiment provides a surface treatment device for a power battery casing. The surface treatment device for a power battery casing includes a cleaning tank 1. The top of the cleaning tank 1 is fixedly connected to two symmetrically arranged side plates 2. The top of the two side plates 2 is fixedly connected to the same mounting plate 3. The bottom of the mounting plate 3 is provided with a mounting groove 5, which is a groove on the mounting plate 3 to accommodate a threaded rod 6 and allow it to rotate.

[0022] A threaded rod 6 is rotatably connected to the inner wall of the mounting slot 5, and a servo motor 4 is fixedly connected to the outer wall of the side plate 2. The end of the threaded rod 6 is fixedly connected to the output end of the servo motor 4. A cleaning mechanism is connected to the threaded rod 6. The cleaning mechanism includes a threaded block 7. The threaded block 7 has a threaded opening. The outer wall of the threaded rod 6 located in the mounting slot 5 has an external thread. The inner wall of the threaded opening has an internal thread that matches the external thread. The outer wall of the threaded rod 6 is threadedly connected to the inner wall of the threaded opening. The outer wall of the threaded block 7 is slidably connected to the inner wall of the mounting slot 5. A cleaning brush 8 is fixedly connected to the bottom of the threaded block 7.

[0023] The end of the threaded rod 6 away from the servo motor 4 is connected to a rotating shaft 14 and a stirring shaft 15 via a meshing mechanism. The meshing mechanism includes a first gear fixedly connected to the outer wall of the threaded rod 6. A second gear and a third gear are respectively fixedly sleeved on the outer walls of the rotating shaft 14 and the stirring shaft 15. The second gear meshes with the first gear and the third gear. Both the rotating shaft 14 and the stirring shaft 15 pass through the side wall of the side plate 2. The rotating shaft 14 is connected to a rotating fixing mechanism. The rotating fixing mechanism includes a cylinder 9 fixedly connected to the outer wall of the side plate 2. An output shaft 10 is fixedly connected to the output end of the cylinder 9. A fixing plate 11 is fixedly connected to the end of the output shaft 10 and the end of the rotating shaft located in the cleaning tank 1. Through the cooperation of the output shaft 10 and the cylinder 9, the device can fix battery housings of different specifications, thus improving the applicability of the device.

[0024] The fixed plate 11 connected to the end of the output shaft 10 is provided with a storage groove. A rotating plate 12 is rotatably connected to the inner wall of the storage groove. Multiple balls 13 are provided between the outer wall of the rotating plate 12 and the inner wall of the storage groove. The balls 13 reduce the friction when the rotating plate 12 rotates, making the rotation smoother.

[0025] The stirring shaft 15 is connected to a mixing mechanism, which includes a clean water tank 17. The stirring blade 16 is fixedly connected to the outer wall of the stirring shaft 15 located in the cleaning tank 1.

[0026] The specific working principle of this utility model is as follows:

[0027] In actual operation, when this device is used, the battery casing is first clamped and fixed by the cooperation of cylinder 9 and output shaft 10. Servo motor 4 starts and drives threaded rod 6 to rotate. Due to the threaded connection between threaded rod 6 and threaded block 7, threaded block 7 moves up and down along mounting groove 5 under the action of rotation of threaded rod 6, thereby driving cleaning brush 8 to move up and down, achieving cleaning of the surface of power battery casing. At the same time, the rotation of threaded rod 6 also drives second and third gears to rotate synchronously through first gear, thereby causing rotating shaft 14 and stirring shaft 15 to rotate synchronously. The rotation fixing mechanism on rotating shaft 14 clamps the power battery casing through the extension and retraction of cylinder 9 and rotates together with rotating shaft 14, achieving all-round cleaning of power battery casing.

[0028] The stirring blades 16 on the stirring shaft 15 rotate inside the cleaning tank 1, ensuring thorough mixing of the cleaning agent and water, thereby agitating the cleaning solution and improving the cleaning effect. The cleaned liquid flows into the clean water tank 17 through the drain pipe 18, where it is filtered or settled, and then returned to the cleaning tank 1 for recycling via the return pipe 19, reducing water waste. The entire process achieves effective cleaning of the power battery casing surface, thorough mixing of the cleaning solution, and recycling of the cleaning solution, improving cleaning efficiency and environmental friendliness.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
