Abstract

The invention provides a device capable of realizing laser punching and laser cleaning by laser polarity inversion. A primarily laser beam emitted by a same optical maser is separated, then two separated beams of lasers are subjected to polarity inversion by a laser beam polarity inversion device, the two beams of lasers form polarity in different polarization directions, and control properties oftwo independent optical masers are presented. According to the device capable of realizing laser punching and laser cleaning by the laser polarity inversion, the purpose that the same laser emitted by the same optical maser can complete two completely different missions or same missions can be realized, for example, different areas of a same cigarette can be punched simultaneously to realize multi-area punching, or Different cigarettes can be simultaneously punched to improve the punching efficiency, or when cigarettes are punched, lasers are used for cleaning glue scale on a punching drum wheel to realize cleaning while punching, so that the production efficiency is improved, and the maintaining workload is reduced.

Description

technical field [0001] The invention relates to a laser processing device, in particular to a device for realizing laser drilling and laser cleaning by using laser polarity conversion. Background technique [0002] At present, cigarette laser processing devices are equipped with multiple lasers to independently emit lasers for different tasks. In order to save space, multiple laser beams are often combined and sent to the inside of the equipment, and then split into different jobs to achieve their work. conduct. The use of multiple lasers requires a relatively large space and consumes a lot of energy, so there is room for improvement. [0003] In the technical solution of a multi-functional punching machine of our company, the patent application number 2018107611451 also conceived that a laser is divided into two beams of lasers through a beam splitter, and then transported to the destination through their own independent transmission devices. The technical solution of mul...
