Gas path switching device of fine cutting machine

Abstract

The invention relates to the field of glass substrate processing and manufacturing, in particular to a gas path switching device of a fine cutting machine. The gas path switching device is connected with a pneumatic device and a fine cutting edge-breaking device and comprises a movable plate, a front baffle and an air storage box. The movable plate is provided with two circular holes which are arranged in a high-low staggered manner; the front baffle is provided with a circular pipeline connector; the pipeline connector is configured to be connected with an equipment pipe orifice; the air storage box is of a box-shaped structure with a single opening, and a main air pipe connector is arranged on the side, away from the opening, of the air storage box; the front baffle is arranged on the periphery of the opening to seal the air storage box; and the movable plate is movably arranged between the opening of the air storage box and the front baffle.

Description

technical field [0001] The invention relates to the field of glass substrate processing and manufacturing, in particular to a gas path switching device for a precision cutter. Background technique [0002] In the process of liquid crystal display substrate processing, the production of glass requires the process of scribing and breaking with precision cutting machine precision, so as to finally meet the customer's finished product size requirements. [0003] Breaking off is to use the upper suction part and the lower breaking part to break off the excess ear material through physical actions. In the process of folding and cutting, because glass breakage will cause a large amount of glass powder (ADG), it is necessary to use the upper adsorption part to vacuum absorb dust, and at the same time, the upper adsorption part needs to absorb, move and release the excess ear material, and discard it to the discharge port for crushing , so the functional dependence on adsorption and...

AI Technical Summary

Problems solved by technology

[0005] 1. The vacuum adsorption pump has no pressure adjustment function, and the vacuum pressure cannot be adjusted according to needs;

[0006] 2. When the glass is broken and cut, it needs a large suction force to absorb the glass powder, and when discarding the ear material, it needs a small suction force to release the ear material. There is no such automatic function;

[0007] 3. It is easy to cause superposition of ear materials, resulting in abnormal quality
