Dust collection device used during edge breaking of substrate glass

Abstract

The invention discloses a dust collection device during edge breaking of substrate glass. The device comprises a substrate glass edge breaking dust collection assembly, a transverse movement adjusting assembly is arranged on one side of the substrate glass edge breaking dust collection assembly, and a longitudinal movement adjusting assembly is arranged above one end, far away from the substrate glass edge breaking dust collection assembly, of the transverse movement adjusting assembly. The extension length of a scissor arm between a first cross arm and a second cross arm is changed through sliding of a movable sleeve on a guiding main sliding rod, and the extension length of the scissor arm between the first cross arm and the second cross arm is kept through automatic jacking meshing between a positioning toothed plate and a positioning rack plate. Through elastic cooperation of a second boss sliding rod jacking spring and a first boss sliding rod jacking spring and vertical sliding of an L-shaped fixing plate on a boss guiding sliding rod, elastic up-down movement of a dust collection isolation plate relative to a rectangular dust collection cover is achieved, and therefore flexible contact between a substrate glass contact rubber cushion and the surface of substrate glass is achieved.

Description

technical field [0001] The invention belongs to the technical field of substrate glass production, and in particular relates to a dust suction device for edge breaking of substrate glass. Background technique [0002] Liquid crystal substrate glass is a high-tech photoelectric glass product with extremely smooth surface, excellent light transmission and ultra-thin. It is mainly used in the high-definition display industry, so the quality requirements of the product are high, and micro-scratches on the surface are not allowed. Glass dust, dirt and other dust-like pollutants. [0003] The existing technology has the following problems: during the processing of the substrate glass, a large amount of glass dust will be generated when the edge is broken, which will adhere to the glass surface, causing micro-scratches, glass powder and other abnormalities to the product, so the edge breaking process in the substrate glass processing The glass powder produced is a major factor cau...

Problems solved by technology

[0003] The existing technology has the following problems: during the processing of the substrate glass, a large amount of glass dust will be generated when the edge is broken, which will adhere to the glass surface, causing micro-scratches, glass powder and other abnormalities to the product, so the edge breaking process in the substrate glass processing The glass powder produced is a major factor causing the defect of the substrate glass, so it is particularly important to remove the glass powder produced during the edge breaking process, so in the production of the substrate glass, there must be a vacuum device to remove the edge breaking when cutting the glass edge The glass powder produced, but the position of the existing dust collection device is relatively fixed. If the position of the glass is deviated, or the position of the lever is adjusted, the position of the suction port and the cutting line will change, which will affect the dust collection effect. The dust device has no isolation plate, and the dust collection space is open, which cannot be effectively blocked from the effective surface of the glass. Therefore, when the edge is broken, the glass powder will not only splash into the effective surface of the glass, but also the dust collection space is large and not concentrated, which will lead to dust collection. Weakened, the effect becomes worse, and the glass powder produced by breaking the edge cannot be completely removed, which will affect the subsequent quality of the product
