[0020] The water supply unit 6 includes a water pump 61 and a delivery pipe 62. The water pump 61 is installed inside the water tank 1, and the outlet of the water pump 61 is connected to the inside of the cutting water tank 2 through the delivery pipe 62. The water pump 61 is electrically connected to the PLC controller 8. The return unit 5 includes a switch valve 51 and a return pipe 53. One end of the return pipe 53 is connected and fixed to the water tank 1, and the other end of the return pipe 53 is connected and fixed to the cutting water tank 2. The switch valve 51 is installed at the connection between the return pipe 53 and the cutting water tank 2. The return unit 5 also includes a filter 52, which is installed on the return pipe 53. When the workpiece is placed into the cutting water tank 2, the filter 52 is used to cut the water. When cutting the water tank 2, the water pump 61 adds water to the cutting water tank 2 through the delivery pipe 62, and the water level is 10-20 mm higher than the cutting surface. During the cutting process, the switch valve 51 is opened, and the water in the cutting water tank 2 flows back to the water tank 1 through the return pipe 53. The return water is filtered by the filter 52. By circulating the water in the cutting water tank 2, the turbidity of the water is reduced. The underwater laser cutting method can effectively reduce smoke and dust. At the same time, the water circulation method facilitates the cooling of the cut workpiece, thereby reducing the thermal deformation of the cut workpiece and improving the processing accuracy.

[0021] The cutting unit 4 includes a laser cutting head 41 and a robotic arm 42. The robotic arm 42 is installed in the middle of the support frame 3, and the laser cutting head 41 is installed at the end of the robotic arm 42. Both the laser cutting head 41 and the robotic arm 42 are electrically connected to the PLC controller 8. The end of the robotic arm 42 drives the laser cutting head 41 to move, thereby adjusting the working position of the laser cutting head 41. The laser cutting head 41 cuts the workpiece. The laser cutting head 41 can use a blue laser to improve its underwater transmission efficiency.

[0022] The workpiece support unit 7 includes a tray 71 and an electric push rod 72. The electric push rod 72 is installed on the top of the connecting frame 9. The tray 71 is fixed to the telescopic end of the electric push rod 72. The tray 71 is movably connected to the cutting water tank 2. The electric push rod 72 is electrically connected to the PLC controller 8. The telescopic end of the electric push rod 72 drives the tray 71 to move up and down. The tray 71 can be moved out of or into the cutting water tank 2. When the tray 71 is moved out of the cutting water tank 2, the workpiece can be placed on the tray 71 or removed from the tray 71. It is easy to operate and facilitates material handling.

[0023] The working principle of the cutting device for processing sheet metal parts of battery boxes provided by this utility model is as follows: The telescopic end of the electric push rod 72 drives the tray 71 to move up and down. The tray 71 can be moved out of or into the cutting water tank 2. When the tray 71 is moved out of the cutting water tank 2, the workpiece can be placed on the tray 71 or removed from the tray 71. When the workpiece is placed into the cutting water tank 2, the water pump 61 adds water to the cutting water tank 2 through the delivery pipe 62. The water level is 10-20 mm higher than the cutting surface. Then, the end of the robotic arm 42 drives the laser cutting head 41 to move, thereby adjusting the working position of the laser cutting head 41. The workpiece is cut by the laser cutting head 41. During the cutting process, the switch valve 51 is opened, and the water in the cutting water tank 2 flows back to the water tank 1 through the return pipe 53. The return water is filtered by the filter 52. By circulating the water in the cutting water tank 2, the turbidity of the water is reduced.
