Background
The utility model relates to a base plate glass technical production field for broken process is broken off with the fingers and thumb in the smart cutting of postprocessing, if produce the glass bits at this in-process, can cause the pollution or directly lead to base plate glass abandonment to the base plate glass surface. The substrate glass is firstly cut before being broken, then four sides of the substrate glass are broken, and the crack depth generated after the four sides of the substrate glass are scribed is 1/5-1/10 of the glass thickness, so that broken glass chips are generated in the breaking process of the substrate glass, and if the broken glass chips adhere to the surface of the substrate glass, the glass can be discarded; the substrate glass bait (the broken part) collides with the buffer box and the bait bucket in the falling process, glass powder is generated in the collision process, and the glass powder can damage the production environment of the processing area (the glass powder is easy to adhere to the surface of the substrate and pollutes the glass); therefore, how to avoid glass dust generated in the normal breaking process and glass powder generated by collision with the buffer box/bait bucket is a key problem.
In the process of processing the substrate glass into a finished product, it is necessary to perform fine cutting of the semi-finished substrate and then grinding of four sides and four corners. The fine cutting is to use a diamond cutter wheel to scribe on the surface of the substrate at a certain cutting amount and pressure and at a corresponding speed, and 0.04-0.08mm of cracks are left on the upper surface of the glass after scribing. And then the scribed substrate is broken off by the breaking-off cutter, and in the breaking-off process, the glass is jacked up by the supporting roller and then pressed down by the breaking-off cutter and adsorbed by the glass to be broken off. In the process, glass dust is generated, the production environment is polluted, and the rejection rate is increased. There are two sources of dust: a. broken glass chips are generated during breaking; b. when the bait (the broken portion) falls down to the bait bucket, glass cullet is produced by collision occurring when the bait falls down. How to better control the glass dust in the production process is a key technical problem and is not well solved at present. This problem can cause pollution to the surrounding environment, affect the product taste, and even result in product waste judgment.
