Description

Technical Field

[0001] The utility model belongs to the technical field of battery recycling equipment, in particular to a battery shell cutting device. Background Art

[0002] As the fastest-growing new energy vehicle, electric vehicles have won the favor of consumers with their environmental and energy-saving advantages, and their market share continues to rise. With the popularization of electric vehicles, the batteries that serve as their power core will gradually degrade in performance after repeated charging and discharging and the increase in service life, and will need to be replaced after reaching a certain level. These retired batteries have high reuse value, making battery recycling an important direction for future industrial development. In the battery recycling process, the first step is to disassemble the battery casing to recover the internal components. The current industry usually uses saw blades and other tools to cut the casing first. However, since waste batteries generally have bulges, the deformation of the battery casing will cause its surface to be uneven. Directly controlling the tool feed with a fixed cutting depth may not cut the casing, or it may cut too deep and cut into the battery cell. Therefore, it is very necessary to develop a battery casing cutting device that can cut according to the contour deformation of the battery casing. Utility Model Content

[0006] Compared with the prior art, the cutting device of the present invention arranges distance sensors on the outside of both saw blades.

[0007] Furthermore, the first cutting feed mechanism includes a first cutting feed screw arranged along the Y-axis direction, a first cutting feed bracket threadedly connected to the first cutting feed screw, and a first cutting motor driving the first cutting feed screw to rotate.

[0008] Furthermore, first cutting feed slide rails parallel to the first cutting feed screw are respectively provided on opposite sides of the first cutting feed screw, and the first cutting feed bracket is slidingly connected to the first cutting feed slide rails. The above arrangement can improve the stability of the first cutting feed bracket during movement.
