Description

Technical Field

[0001] The present invention relates to the technical field of battery cutting and processing, and in particular to a laser cutting device for battery processing. Background Art

[0002] The structure of an existing laser cutting device, such as a laser cutting device disclosed in patent publication number CN103180085B, uses a laser beam to cut a workpiece while blowing oxygen as an auxiliary gas to the cutting part. The laser cutting device includes: an emission device that emits a laser beam with a wavelength shorter than that of a CO2 laser and is used to cut the workpiece, wherein the workpiece has a thickness of 10 mm to 50 mm that generates a molten pool inside when irradiated by the laser beam; and a convergence device that converges the laser beam so that the cross-sectional shape of the laser beam emitted from the emission device is elliptical and the major axis direction of the ellipse is consistent with the cutting direction of the workpiece, and the workpiece is cut by consuming the energy of the laser beam on the front side of the cutting direction of the workpiece to melt the workpiece, and consuming the energy of the laser beam on the rear side of the cutting direction of the workpiece to increase the temperature of the molten workpiece.

[0003] When using the above-mentioned laser cutting device to cut thick soft materials, such as fabrics, rubber and other materials, the laser beam emitted by the laser cutting device can continuously cut the material, that is, cut a continuous straight line to form a cut.
