Abstract

The invention discloses a high-speed and high-precision tab cutting method and device based on vision guidance. The tab cutting method comprises the following steps: placing a tab material band on a synchronous conveyor belt; utilizing a main transmission motor to drive the synchronous conveyor belt to move, and conveying the synchronous conveyor belt forwards; through a feedback encoder, triggering and driving an industrial camera to carry out vision detection on the tab material band, and obtaining the position image of the tab material band; extracting positions corresponding to the two edge lines of the tab material band; calculating the actual central line position of the tab material band; calculating the central position deviation value of the tab material band; immediately transmitting the central position deviation value of the tab material band to a laser cutting device; and by the laser cutting device, according to the deviation numerical value obtained through the vision detection of the tab material band, immediately triggering laser to make corresponding position adjustment when the tab material band reaches the cutting position of the laser cutting device. The high-speed and high-precision tab cutting method and device based on vision guidance have the advantages of being high in cutting precision, being high in product quality and the like.

Description

technical field [0001] The invention relates to the field of laser cutting, in particular to a high-speed and high-precision tab cutting method and equipment based on vision guidance. Background technique [0002] In the field of laser cutting, especially the laser cutting of battery tabs, it is necessary to use a laser cutting device to cut the tabs of the strip. However, due to the error of the edge angle of the material tape itself, and the position deviation of the material tape during the transmission process, there will be a large deviation in the final cutting position of the laser cutting device, and the error rate of the product is high. , It may lead to poor product quality and low pass rate of products. [0003] In view of this, the purpose of the present invention is to provide a new technical solution to solve the existing technical problems. Contents of the invention [0004] In order to overcome the shortcomings of the existing technology, the present inve...
