Integrated device for dust adsorption and air-entrapping

Abstract

The invention provides an integrated device for dust adsorption and air-entrapping with adjustable installation height. The integrated device for dust adsorption and air-entrapping comprises a lens air blowing device, an air-entrapping protection cover and a telescopic cover for connecting the lens air blowing device and the air-entrapping protection cover, wherein the telescopic cover has a function of extending and contracting so as to adjust the height of the whole device, the lens air blowing device and the air-entrapping protection cover are both connected with a quick coupling, and a speed control valve connected with the quick coupling. The integrated device for dust adsorption and air-entrapping with the adjustable installation height can effectively absorb and remove soot produced by laser processing, isolate the pollution of soot to a laser focus lens, create an environment-friendly environment for the laser processing and improve the quality of the laser processing. The device has the advantages of simple structure, safety, reliability and low maintenance cost, and is very suitable for equipment utilizing galvanometer scanning to carry out laser processing.

Description

technical field [0001] The invention relates to the field of laser processing, in particular to a height-adjustable integrated device for dust collection and air filling that uses the scanning function of a vibrating mirror and a vacuum adsorption workbench for absorbing workpieces in laser processing. Background technique [0002] Due to the good quality of laser processing products, it can quickly solve the situation that complex graphics are difficult to process, and it has been more and more widely used in the PCB industry. In order to improve the processing quality of parts and other needs, it is often necessary to add nitrogen, oxygen and other auxiliary gases during laser processing, which requires a gas filling device, which must solve the following problems. [0003] First, when using platform movement and galvanometer scanning as the processing method, when the relative position of the platform and the laser focusing mirror remains unchanged, the range of laser pro...

Problems solved by technology

[0004] Second, the processing of soft boards in the PCB industry will produce a large amount of visible and invisible smoke and dust, which are mostly toxic and harmful substances. When these toxic and harmful particles diffuse in the air, they will cause harm to the human body and accumulate on the workpiece. Blocking the laser beam nearby will cause the quality of laser processing to decline, so it is of great significance to absorb the smoke and dust generated by processing and provide a clean environment for laser processing

[0006] Fourth, as the application range of laser processing becomes more and more extensive, the existence of plug-ins such as patch originals in PCB industry processing boards, the need for vacuuming and the relatively fixed position of the air inlet and the processed parts can no longer meet the needs. Adjust within a certain range
