Background

Rhinestone (crystal, rhinestone) is also known as crystal diamond and rhinestone. The main component is crystal glass, which is an accessory of the ornament obtained by cutting artificial crystal glass into diamond facets, and the material is more economical, and has the visual effect of diamond-like dazzling feeling. Therefore, the rhinestone is popular, and is generally used in the ornament design of the middle grade. Classifying rhinestones: the color can be divided into: white diamond, colored diamond (such as pink, red, blue, etc.), colored diamond (also called AB diamond), and colored AB diamond (such as red AB, blue AB, etc.).

The patent publication No. CN100484711 discloses a method for polishing and grinding the end face of a rhinestone, which comprises arranging rhinestones and then performing polishing and grinding on the end face of the whole rhinestone (or performing overall paint spraying by using a plastic sucking disc) by using a plastic sucking disc (a circular disc on which a large number of adsorption holes are uniformly distributed and which is bonded to the adsorption holes by rosin and the like) of the rhinestones, wherein the rhinestones are required to be removed from the plastic sucking disc after the polishing and grinding.

In the prior art, a rhinestone is usually separated from a plastic sucking disc through an automatic discharging device, for example, a patent with the application number of 200920192598.3 discloses an automatic discharging machine, for example, a patent with the application number of 201620254706.5 discloses a discharging device after silver spraying on the rhinestone, for example, a patent with the application number of 201710355572.5 discloses a novel discharging machine, and for example, a patent with the application number of 201811617602.6 discloses an automatic discharging machine.
