Description

Technical Field

[0001] The present invention belongs to the technical field of manufacturing and processing of liquid crystal glass substrates, and particularly relates to a dust collection device for a liquid crystal glass substrate to rest on. Background Art

[0002] In the production and manufacturing process of glass substrates, during forming and cutting, the liquid crystal glass substrate is conveyed to the longitudinal cutting machine for semi-finished products through a conveyor tooling plate. Then, the front rests on both sides in the front and the rear rests on both sides in the rear of the longitudinal cutting machine simultaneously extend (the front rest is provided with a dust collection device for surface A, and the rear rest is provided with a dust collection device for surface B), approaching the outer surface of the glass substrate. At this time, a row of breaking plate suction cups on the rear rest extends to suck the edge of the glass substrate, and the two side cutter wheels on the front rest extend to contact the outer surface of the glass substrate and start longitudinal cutting from top to bottom. The dust collection device for surface A on the front rest and the dust collection system for surface B on the rear rest start running simultaneously, the dust collection device is opened, and the dust collection port starts to suck air into the dust collection box all the time. After cutting is completed, the two side cutter wheels retract and return to their original positions from bottom to top. A row of breaking plate suction cups on the outside of the rear rest performs plate breaking. After plate breaking is completed, the dust collection devices on the front rest and the rear rest are also closed simultaneously to stop sucking air.

[0003] The prior art has the following problems: During the process of sucking air into the dust collection pipe, the dust collection device for surface A of the front rest sucks a large amount of glass powder generated during cutting and plate breaking on the A surface of the glass substrate, and the dust collection device for surface B of the rear rest sucks a large amount of glass powder generated during cutting and plate breaking on the B surface of the glass substrate. However, there will be residual glass powder left on the surface of the glass substrate. The glass powder not sucked by the dust collection devices on the front and rear rests remains on the surface of the glass substrate, which will lead to an increase in the rejection rate, a low yield rate in subsequent processing procedures, and an increase in production costs in subsequent processing procedures. Therefore, there is an urgent need for a dust collection device for a liquid crystal glass substrate to rest on to solve the above problems. Summary of the Invention
