Embodiment 1

[0021] like figure 1 As shown in the figure, a method for dismantling and recycling the cover plate of a square power battery first uses a cutting tool to cut a slit on the cover plate on the outer periphery of the pole along the radial direction of the pole, the outer end of the incision extends to the outer edge of the cover plate, and the inner end of the incision Extend to the inner edge of the cover plate in contact with the pole; then use the clamp to clamp the cover plate, so that the cover plate rotates in the direction away from the cutout, and the cutout is opened accordingly. When it falls down, the plastic bracket under the cover is separated at the same time, which realizes the disassembly and recycling of the pole, the cover and the plastic bracket. Wherein, the battery cover is a cover disassembled from the battery, and the cutting tool is an impact knife.

Embodiment 2

[0023] like figure 1 As shown in the figure, a method for dismantling and recycling the cover plate of a square power battery first uses a cutting tool to cut a slit on the cover plate on the outer periphery of the pole along the radial direction of the pole, the outer end of the incision extends to the outer edge of the cover plate, and the inner end of the incision Extend to the inner edge of the cover plate in contact with the pole; then use the clamp to clamp the cover plate, so that the cover plate rotates in the direction away from the cutout, and the cutout is opened accordingly. When it falls down, the plastic bracket under the cover is separated at the same time, which realizes the disassembly and recycling of the pole, the cover and the plastic bracket. Wherein, the battery cover is a waste cover, and the cutting tool is an impact knife.

Embodiment 3

[0025] like figure 1 As shown in the figure, a method for dismantling and recycling the cover plate of a square power battery first uses a cutting tool to cut a slit on the cover plate on the outer periphery of the pole along the radial direction of the pole, the outer end of the incision extends to the outer edge of the cover plate, and the inner end of the incision Extend to the inner edge of the cover plate in contact with the pole; then use the clamp to clamp the cover plate, so that the cover plate rotates in the direction away from the cutout, and the cutout is opened accordingly. When it falls down, the plastic bracket under the cover is separated at the same time, which realizes the disassembly and recycling of the pole, the cover and the plastic bracket. Wherein, the battery cover is a waste cover, and the cutting tool is an impact knife.

[0026] The cover board should be dedusted and degreased before cutting. The specific operation is: soak the cover board in the d...

Abstract

The invention discloses a disassembly and recovery method of a square power battery cover plate and relates to the technical field of battery material recovery. The method comprises the following steps: firstly, cutting a notch in a cover plate at the periphery of a pole along the radial direction of the pole by utilizing a cutting tool, extending the outer end of the notch to the outer edge of the cover plate, and extending the inner end of the notch to the inner edge of the cover plate in contact with the pole; then, clamping the cover plate by utilizing a clamp, and enabling the cover plateto rotate along the direction away from the notch so as to open the notch; and after the cover plate rotates for a certain angle, enabling the pole to automatically fall off from the cover plate, andsimultaneously, separating a plastic bracket below the cover plate, thereby realizing disassembly and recovery of the pole, the cover plate and the plastic bracket. Disassembly of the cover plate andseparation and recovery of all parts can be quickly realized by utilizing the cutting tool and the clamp, so that the pole is automatically separated from the cover plate.

Description

Technical field: [0001] The invention relates to the technical field of battery material recycling, in particular to a method for dismantling and recycling a square power battery cover. Background technique: [0002] At present, there are three main packaging forms of mainstream power lithium batteries, namely cylinder, square and soft package. Different packaging structures mean different characteristics, and they each have advantages and disadvantages. The inside of the square battery adopts winding or laminated technology, which has a better protection effect on the battery cell than the pouch battery, and the safety of the battery cell is also greatly improved compared with the cylindrical battery. The prismatic battery cover is an important component of the prismatic battery, including the cover body, positive pole, negative pole and plastic bracket, and the processing materials involve aluminum, copper and plastic. In order to realize the recycling and reuse of the co...
