Description
Technical Field
The invention relates to the technical field of laser cutting, in particular to a laser cutting machine for a lithium battery pole piece.
Background
After the porous electrode is coated and rolled, the electrode plate is cut to reach the required design structure. At present, pole piece cutting mainly comprises three modes, (1) disc cutting; (2) die stamping; (3) laser cutting.
The traditional punching mode of the disc cutting and the mould is to use a cutter or a mould, and the principle that the materials are subjected to plastic deformation after being stressed and separated from each other after cracks are generated is utilized to cut the pole pieces. Both of these modes put high demands on the strength, rigidity and accuracy of the tool or die. For the cut formed after cutting, the problems of burrs, slag hanging and the like generally occur. Since the cutting process is a contact process, the coating friction force of the electrode is large, which can lead to increased wear of the contact tool and passivation of the die, and thus the die needs to be reground and even replaced.
Compared with the traditional cutting process, the laser process is very flexible, different geometric shapes can be easily adjusted, a new cutting die is not required to be manufactured for different products, and the disadvantages caused by the cutter or the die can be overcome.
The use of laser to cut has the advantages that firstly, the cutting edge burrs can be stably controlled within 0.01mm, resulting in extremely high yield; secondly, only one-time cost investment is needed for laser cutting, and no cutter changing and die changing cost exists in the subsequent production process and during die changing, so that the long-term cost is calculated, and the production cost can be reduced by adopting laser film making; thirdly, the laser cutting has no processing stress and can not cause the falling of powder at the edge. Although the cutting mode has excellent performance, the cutting of the laser cutting pole piece has some defects in the actual operation process, wherein the laser cutting can generate carbonized edges (also called heat affected zone), because the cutting is performed by utilizing high-density laser energy, a certain degree of carbonized edges can be inevitably generated when the pole piece is cut off, and the cathode material can generate a certain copper exposure phenomenon, but the heat affected zone can be controlled within 0.1mm, and in addition, a large amount of dust can be generated in the laser cutting process, so that the collection and treatment of the dust are quite difficult problems.
