Problems solved by technology

[0011] However, when the scanner is driven at high speed, constant quality can be ensured in the straight section, but there is a disadvantage that the faster the speed, the worse the quality is in the corner section of the vertex portion of the quadrangle
The biggest problem is that the speed of the workbench changes sharply when it passes a straight line corner. This kind of sharp speed change is difficult for mechanical devices, and it is difficult to reach the speed of 60m / min in a short time.

Abstract

The present invention relates to an apparatus and method for cutting electrode foils. The apparatus and method for cutting electrode foils includes: a rotating body disposed vertically spaced by a predetermined distance so as to be parallel to a working table; a rotating shaft disposed at the center of the rotating body and driven by a first driver to rotate the rotating body at a predetermined speed; and a scanner disposed at the end of one side of the rotating body to emit a laser beam onto an object to be processed according to the rate of change in speed based on the rotation angle and rotating speed of the rotating body and the processing size of the object to be processed.

Description

technical field [0001] The present invention relates to a cutting device and method, more particularly to an electrode foil cutting device and method. Background technique [0002] With the increasing interest in electric vehicles around the world and the intensification of research and development competition, it can be predicted that related industries will also grow significantly, especially the secondary battery market will become the center. [0003] Electric vehicles started with hybrid HEV (Hybrid Electric Vehicle; hybrid electric vehicle), and are developing into PHEV (Plug in Hybrid Electric Vehicle; plug-in hybrid electric vehicle) and EV (Electric Vehicle; pure electric vehicle). In addition, the reality is that the research and development of batteries as a power source is the main focus of the electric vehicle market, and battery companies are doing their best to preempt new technologies. [0004] Under such a realistic background, in the secondary battery indu...
