Material collecting mechanism and method for full-automatic pole piece laser cutting forming machine

Abstract

The invention discloses a material collecting mechanism for a full-automatic pole piece laser cutting forming machine. The material collecting mechanism comprises a material collecting mechanical hand, a pole piece cutting position, a waste collecting box and a pole piece collecting jig and further comprises an isolation board locating assembly. The isolation board locating assembly is provided with an isolation board used for covering the surface of a pole piece in the pole piece cutting position. The material collecting mechanical hand comprises a mechanical hand body used for grabbing and placing the pole piece and the isolation board. The material collecting mechanical hand further comprises a drive assembly used for driving the mechanical hand body to move among the pole piece cutting position, the waste collecting box, the pole piece collecting jig and the isolation board locating assembly. Before laser cutting is conducted, the isolation board is placed on the surface of the pole piece in the pole piece cutting position through the material collecting mechanical hand, so that in the laser cutting process, most metal particles only can be splashed to the surface of the isolation board and cannot be splashed to the surface of the pole piece, the metal particles attached to the surface of the cut pole piece is effectively reduced, and the safety performance of a lithium battery is improved. The invention further discloses a material collecting method.

Description

technical field [0001] The invention relates to the technical field of lithium battery production equipment, in particular to a material receiving mechanism and a material receiving method of a fully automatic pole piece laser cutting forming machine. Background technique [0002] In the production process of lithium batteries, it is necessary to cut the strip-shaped pole piece material into a single piece of pole piece. This process is called pole piece forming. After the pole piece is formed, it needs to be collected into the pole piece collection jig, that is, the receiving process. At present, various battery equipment manufacturers mainly have three pole piece forming methods: punching machine, metal die cutting machine, and laser cutting machine. Especially the fully automatic pole piece laser cutting machine has good cutting quality, high degree of automation, and high production efficiency. Advanced advantages. [0003] Among them, the fully automatic pole piece la...

AI Technical Summary

Problems solved by technology

[0004] However, in the fully automatic pole piece laser cutting forming machine of the prior art, during the laser cutting process, since the pole piece material will be instantly melted and sputtered, a certain amount of metal particles (the pole piece material is metal) will be sputtered onto the pole piece. The surface of the sheet, resulting in more metal particles attached to the surface of the cut pole piece, and these attached metal particles have great harm to the safety performance of the lithium battery, such as: short circuit, etc.
