[0016] Compared with the prior art, the present application has the following advantages:

[0017] 1. The flipping clamping mechanism installed on the upper surface of the support plate allows for clamping of the battery box during the milling of the weld seams, improving the ease of flipping the battery box after clamping. This facilitates the flipping and milling of the four weld seams of the battery box. The dust filter mechanism installed on the side surface of the milling motor filters the dust generated during milling, thereby reducing the emission of dust in the working environment. The milling debris collection mechanism set in the middle of the support plate collects the milling debris, thereby reducing the pollution of the surrounding environment by the debris.

[0018] 2. A flipping clamping mechanism consisting of a support plate, a hydraulic telescopic rod, a motor, a clamping iron plate, and a rubber plate is used. The telescopic end of the hydraulic telescopic rod is fixed to the clamping iron plate via the motor, facilitating the clamping of the battery box by the hydraulic telescopic rod carrying the clamping iron plate. The motor is used to flip the battery box, which facilitates milling of the four weld seams of the battery box. The rubber plate is fixed to the clamping iron plate via a magnet and a limiting hole. The magnet is installed in the limiting hole to facilitate the positioning of the rubber plate. The anti-slip grooves on the surface of the rubber plate increase the surface roughness of the rubber plate, thereby increasing the stability of the clamping of the battery box.

[0019] 3. The dust filtration mechanism consists of a negative pressure pump, a suction cup, a filter ball, vents, and filter cotton. The air inlet of the negative pressure pump is connected to the suction cup through a pipe, and the air outlet of the negative pressure pump is welded with a filter ball. The suction force generated by the negative pressure pump is used to draw in dust through the suction cup, and the air drawn in by the negative pressure pump is discharged into the filter ball. The air inside the filter ball is filtered by the filter cotton and discharged through the vents. The filter cotton is protected from backflow of dust into the negative pressure pump by an internal flow-blocking device. The flow-blocking device includes a guide tube fixed in the middle of the filter cotton and a rubber tube sleeved on the upper end of the guide tube. The rubber tube is bonded and fixed to the inner surface of the filter cotton.

[0020] 4. The collection mechanism consists of a slag discharge window, a protective net, an exhaust fan, a slag collection hood, a limiting plate, and a magnetic rod. The exhaust fan installed inside the slag discharge window provides downward airflow, which collects the milling debris inside the slag collection hood under the action of the airflow. The slag collection hood is fixed to the lower surface of the support plate by the limiting plate and the magnetic rod. The magnetic rod is fixed in the hole opened in the slag collection hood and the limiting plate by magnetic force, which facilitates the disassembly and assembly of the slag collection hood.
