Planetary turnover type 3D curved glass polishing machine

Abstract

The invention discloses a planetary turnover type 3D curved glass polishing machine. The machine comprises a polishing mechanism and a planetary turnover type polishing carrier arranged right above the polishing mechanism; the planetary turnover type polishing carrier comprises a carrying plate containing chamber, a carrying plate, at least two sub-planetary carrying plates, and a transmission assembly, wherein the top of the carrying plate containing chamber is opened, the carrying plate is arranged in the carrying plate containing chamber, the at least two sub-planetary carrying plates are arranged on the carrying plate, and the transmission assembly is arranged right below the carrying plate contaning chamber. According to the machine, the machine is provided with the planetary turnovertype polishing carrier, it is ensured that the rotating angle and amplitude of every 3D curved glass is uniform, and thus the polishing uniformity is improved; polishing scraps can also be timely discharged; and the pressure applied to the 3D curved glass by a polishing disk is controlled in real time, so that the problem of insufficient polishing or excessive polishing is solved, and in this way, the surface quality of the 3D curved glass is improved.

Description

technical field [0001] The invention relates to the field of 3D curved glass preparation, in particular to a planetary turnover type 3D curved glass polishing machine. 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 experience. [00...

Problems solved by technology

[0004] Due to the specificity of its own structure, 3D curved glass has more curved surfaces on its surface, which leads to the following defects in existing polishing machines: due to the unevenness of the outer surface of 3D curved glass, the existing polishing disc It is difficult for the polishing brush to penetrate deep into the 3D curved glass, which leads to different sizes of the 3D curved glass being polished, resulting in uneven polishing, which cannot meet the design requirements; moreover, the existing polishing mechanism cannot implement the adjustment of the polishing disc during polishing. The pressure applied on the 3D curved glass may easily lead to insufficient polishing size or excessive polishing; thirdly, the rotation angle and speed of the carrier are not easy to control, and the rotation range of multiple 3D curved glasses carried on the carrier is also difficult. Unified control, 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; finally, the volume and specific gravity of the polishing debris generated during the grinding and polishing process are small, and it is easy to contaminate the carrier. Discharge, which in turn affects equipment heat dissipation and polishing accuracy
