Goods sorting device, goods sorting method and optical element manufacturing device

Abstract

The invention provides a goods sorting device, a goods sorting method and an optical element manufacturing device. The goods sorting device comprises an inclined surface part (1) which is in a preset angle (theta) with the horizontal surface, multiple through holes (K) are distributed on the inclined surface part, the goods sorting device is used for sorting first goods, second goods and third goods, the rolling resistance and / or the friction force between the first goods and the inclined surface part are / is greater than the rolling resistance and / or the friction force between the second goods and the inclined surface part, and the third goods can be discharged out of the inclined surface part through the through holes.

Description

technical field [0001] The invention relates to an article classification device, a classification method and an optical element manufacturing device for classifying articles with different characteristics. Background technique [0002] Conventionally, a grinding method has been commonly used as a technique for deforming a material into a desired shape. For example, for optical elements such as lenses, a glass block with a size similar to that of the lens is made by cutting, grinding and grinding the glass block, and then the glass block is chamfered to obtain a glass glass product for pressing , by press-molding the glass glass product for pressing to produce a blank, and further grinding the blank to manufacture optical elements such as the above-mentioned lens. [0003] However, in the past, the chamfering of the glass block was carried out by rubbing the glass block in the presence of abrasives. Therefore, after chamfering, glass products for pressing (hereinafter also ...

AI Technical Summary

Problems solved by technology

[0003] However, in the past, the chamfering of the glass block was carried out by rubbing the glass block in the presence of abrasives. Therefore, after chamfering, glass products for pressing (hereinafter also referred to as glass blocks), abrasives, etc. And the state where sludge composed of grinding liquid, powder, etc. exists at the same time, the work of separating glass block, abrasive, and sludge to recycle glass block becomes extremely complicated

Moreover, not only the separation of glass blocks, abrasives, and sludge, but also the classification of groups of objects with different properties is often very complicated
