A cyclone dust removal device

Abstract

The invention relates to a cyclone dust removal device, in particular to a cyclone dust removal device for a laser side sweeping machine and a laser film engraving machine. The cyclone dust removal device comprises a cyclone inner barrel, a cyclone outer barrel, an air curtain inner ring and an air curtain outer ring; one end of the cyclone inner barrel is connected with a dust removal pipeline and is used for feeding dust into the dust removal pipeline; the other end of the cyclone inner barrel is connected with one end of the cyclone outer barrel; an air cavity for converting compressed air into cyclone air flow is formed at the joint of the other end of the cyclone inner barrel and the cyclone outer barrel; the other end of the cyclone outer barrel is connected with a compressed air pipeline and is used for receiving the compressed air; the air curtain inner ring is connected with the cyclone outer barrel by an internal screw thread processed inside the air curtain inner ring and is connected with the air curtain outer ring by an external screw thread processed outside the air curtain inner ring; and both the air curtain inner ring and the air curtain outer ring are used for preventing the dust from being diffused. The cyclone dust removal device disclosed by the invention can effectively remove the dust and improve the production efficiency, and is easy to be connected and integrated with the external dust removal pipeline.

Description

technical field [0001] The invention relates to a cyclone dust removal device, in particular to a cyclone dust removal device used for laser edge cleaning machines and laser film engraving machines. Background technique [0002] The production process of thin-film solar cells involves the thin-film deposition of the bottom electrode, the intermediate photovoltaic effect layer and the surface ohmic contact electrode layer, as well as the scribing of each layer and the removal of the surrounding film layers. Compared with the traditional mask method, laser scribing technology has higher production efficiency and stable product quality, and has been well applied in the manufacturing process of thin-film solar cells. However, in the process of scribing and edge-cleaning thin-film batteries by laser, it is easy to generate a large amount of tiny dust, and most of the dust cannot reach the dust removal system, and if the dust removal efficiency of the dust removal system is low, t...

Problems solved by technology

However, in the process of scribing and edge-cleaning thin-film batteries by laser, a large amount of tiny dust is easy to be generated, and most of the dust cannot reach the dust removal system, and if the dust removal efficiency of the dust removal system is low, the generated dust will contaminate the cells It itself and the clean production workshop will affect the conversion efficiency of the cell, and will also pollute the equipment workbench, causing inconvenience to equipment maintenance or battery production
