Problems solved by technology

[0003] However, for some situations where the space is small and it is impossible to realize the coexistence of multiple lasers and multiple optical transmission devices, that is, use one laser to send out laser beams that are separated into two beams of lasers with independent control characteristics, and then transport them through the same optical delivery device. After the working position, it is restored and separated into two laser beams with independent control characteristics, so as to achieve the purpose of applying laser in the case of narrow space, where it is impossible to realize the coexistence of multiple lasers and multiple optical transmission devices.

Abstract

The invention relates to a device for realizing merging and separating optical transmission through laser polarity conversion. According to the device, laser beams emitted by the same laser device areseparated, then polar conversion is carried out on the split two beams of laser by utilizing a light beam polarity conversion device, so that the two beams of light beams form polarities of differentpolarization directions, and therefore the control characteristics of two independent lasers are embodied; and according to the device, the same laser emitted by one laser can complete two completelydifferent or same tasks.

Description

technical field [0001] The invention relates to a laser processing device, in particular to a device for combining and separating optical transmission through laser polarity conversion. Background technique [0002] At present, laser processing devices for thin rods and cigarettes 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 tasks. To realize its work; another application is to use the output laser of the same laser to split the light, divide it into at least two independent laser beams, and then transport the beams to the working position through separate optical transmission. [0003] However, for some situations where the space is narrow and it is impossible to realize the coexistence of multiple lasers and multiple optical transmission devices, that is, use one laser to send out laser beams that are ...
