Two-stage planet gear type polishing carrier for 3D bent glass

Abstract

The invention discloses a two-stage planet gear type polishing carrier for 3D bent glass. The two-stage planet gear type polishing carrier comprises a sun wheel assembly and at least two sets of planet epicyclic type carriers meshing with the periphery of a sun wheel; the sun wheel assembly comprises a sun wheel supporting frame and the sun wheel arranged on the sun wheel supporting frame; a polishing solution collecting plate and a planet carrier are sequentially arranged right above the sun wheel from up to down and the polishing solution collecting plate and the planet carrier rotate synchronously with the sun wheel; the planet carrier is sequentially provided with feeding and discharging stations and at least one polishing station in the circumferential direction; the planet epicyclictype carriers are installed above the planet carrier, and the number of the planet epicyclic type carriers is equal to the sum of the number of the feeding and discharging stations and the number of the polishing stations. According to the two-stage planet gear type polishing carrier for the 3D bent glass, the polishing uniformity is improved, the 3D bent glass can be changed between each stationrepeatedly at the same time, the degree of automation and the polishing efficiency are improved, polishing chips generated in the process of polishing can be discharged in time, polishing solutions are recycled further, the production cost is lowered, and the requirement of environment protection is met at the same time.

Description

technical field [0001] The invention relates to the field of preparation of 3D curved glass, in particular to a two-stage planetary gear type polishing carrier for 3D curved glass. Background technique [0002] The glass cover plates used on the displays of smart terminal products in the existing market can be divided into: 2D glass, 2.5D glass and 3D curved glass. Among them, 2D glass is ordinary pure flat glass without any curved design; 2.5D glass is The middle is a flat design, and the edge adopts a curved design; the 3D curved glass can be designed as a curved arc in the middle and the edge. 3D curved glass is mainly bent by a hot bending machine, which can achieve a higher bending arc. Some physical properties of 3D curved glass are obviously better than 2D and 2.5D glass. 3D curved glass has the advantages of being light and thin, transparent and clean, anti-fingerprint, anti-glare, hard, scratch-resistant, and good weather resistance. Better display and touch exper...

Problems solved by technology

[0004] Due to the specificity of its own structure, the 3D curved glass has more curvature on the surface. Therefore, the 3D curved glass should be rotated from time to time in the grinding and polishing process to make the surface polishing intrusion uniform in size and meet the design requirements. When the 3D curved glass rotates to the specified position, it is necessary to brake the continuously rotating planetary gear assembly and stop at this position for a certain period of time. The existing planetary gear transmission mechanism has the following problems: the rotation angle and speed of the vehicle It is not easy to control, and it is also difficult to uniformly control the rotation range of multiple 3D curved glasses carried on the carrier, which makes it difficult to control the size of the polishing intrusion of the 3D curved glass, which eventually leads to uneven polishing and cannot meet the design requirements; secondly, the manufacturing There is a delay in the dynamic feedback, so that there is a large deviation in the positioning position of the 3D curved glass, which affects the polishing quality; again, after braking, the gear cannot be stopped in a short period of time, resulting in a further increase in the positioning deviation of the 3D curved glass, and finally The polishing error is large, which cannot meet the design requirements; finally, the volume and specific gravity of the polishing debris generated during the grinding and polishing process are small, and they are easy to be contaminated in the carrier and difficult to discharge, which in turn affects the heat dissipation of the equipment and the polishing accuracy
