AI Technical Summary

Technical Problem

In existing laser patterning technology, the wind field system cannot achieve timely, uniform, and stable purging of processing by-products during large-format processing while ensuring uniformity and appropriate force. This results in large equipment size, high cost, and low processing quality and efficiency.

Method used

An ion wind assembly is used, consisting of N pairs of ion wind components. Each component has two modes: blowing and pumping. By ionizing air with high voltage through electrodes, a charged compressed air flow is formed. Combined with the connecting components, the air moves synchronously with the laser processing head to form a wind field opposite to the laser scanning direction, thereby achieving local purging and pumping.

Benefits of technology

In the process of large-format laser patterning, timely, uniform and stable purging of processing by-products is achieved, reducing equipment size and cost, improving processing quality and efficiency, suppressing plasma shielding effect and enhancing local heat dissipation capacity.

Abstract

This invention discloses a wind field system and laser processing method for laser patterning, belonging to the field of laser patterning technology. The ion wind component is divided into a central cavity, a first cavity, and a second cavity. The central cavity serves as a blowing channel; in blowing mode, air compressed by an air compressor is ionized under the high pressure of electrodes, forming a charged compressed air stream, which is then blown out from the outlet to the processing area. Both the first and second cavities serve as extraction channels; in extraction mode, the suction force of a dust collector removes processing byproducts from the processing area. The ion wind component is fixedly connected to the laser processing head and can move with the laser processing head, generating a synchronously moving local ion wind field. This allows for timely, uniform, and stable removal of processing byproducts during large-format laser patterning with a small equipment size and low cost, while ensuring wind field uniformity and appropriate force.
