Hard material finishing device

Abstract

The invention relates to a hard material finishing device. The hard material finishing device comprises a base, a first displacement mechanism, a second displacement mechanism and a laser generator, wherein the base is provided with a working table capable of moving; the working table is provided with a hard material; the first displacement mechanism is arranged on the base corresponding to the working table; the second displacement mechanism is arranged on the first displacement mechanism; the laser generator is arranged on the second displacement mechanism, and is selectively driven by the second displacement mechanism or the first displacement mechanism and the working table to move along the edge of the hard material; and lasers generated by the laser generator are projected to the edge of the hard material, so that the energy of the lasers finishes the edge. The hard material finishing device has the beneficial effects of quicker processing speed, better surface treatment effect and precision, no deformation or abrasion of the hard material caused by processing and no generation of such pollution problems as chips and dust.

Description

technical field [0001] The invention relates to a mechanical device utilizing laser processing, in particular to a hard material trimming device. Background technique [0002] Since the glass will show sharp and rough edges after being cut, the edge of the glass must be trimmed before the glass can continue to be used in various products. The edge trimming of existing glass is mostly done by grinding, that is, the glass to be ground is first fixed on the machine, and then the grinding wheel is controlled to touch the edge of the glass along a predetermined path. In order to make the edge of the ground glass have better surface precision, different grinding wheels with coarse and fine grinding grain sizes are usually used to process the object, so as to make the quality of the finished product meet the requirements. [0003] However, since the above-mentioned grinding processing method must repeatedly replace the grinding wheel according to the grinding roughness and finenes...

AI Technical Summary

Problems solved by technology

[0003] However, since the above-mentioned grinding processing method must repeatedly replace the grinding wheel according to the grinding roughness and fineness, and must also design a specific fixture or a complicated grinding wheel action path in accordance with the shape of the object to be ground, the grinding process time Long, unable to effectively control cost and finished product quality

Moreover, a large amount of debris and dust will be generated after the grinding wheel contacts the edge of the glass, which is likely to cause pollution problems, and the resulting cost of dust collection and chip removal equipment

Furthermore, when the glass is in contact with the grinding wheel, there will be processing stress concentration, and even deformation will cause the glass to be brittle and so on.
