Problems solved by technology

Therefore, this processing method is improved compared with the first processing method, but this processing method has an insurmountable technical bottleneck-only rough grinding wheels and fine grinding wheels can be installed on the horizontal shaft of the equipment used. One of the wheels, using a rough grinding wheel, can only guarantee the processing efficiency but not the processing quality; while using a fine grinding wheel, can guarantee the processing quality but not the processing efficiency

Embodiment Construction

[0025] Such as figure 1 As shown, the glass panel or glass rear cover plate 2.5D molding process method of the present invention includes a clamping positioning step, a horizontal axis grinding step and a main shaft forming step; the horizontal axis grinding step includes a rough grinding step and a fine grinding step. Grinding step; the clamping positioning step, rough grinding step, spindle forming step and fine grinding step are sequentially performed by a Z-axis fine and rough double grinding device; the unprocessed glass panel and glass back cover are successively passed through the clamping After the four steps of positioning step, coarse grinding step, spindle forming step and fine grinding step, a shaped glass panel and a shaped glass rear cover are respectively formed.

[0026] Specifically, the Z-axis fine-rough double grinding device includes an adsorption device; the clamping and positioning step is completed by the adsorption device, specifically: the adsorption d...

Abstract

The invention discloses a 2.5 D forming process method of glass panels or rear glass cover plates, which comprises a clamping and positioning step, a horizontal-axis grinding step and a main-axis forming step, wherein the horizontal-axis grinding step comprises a rough grinding step and an accurate grinding step; the clamping and positioning step, the rough grinding step, the main-axis forming step and the accurate grinding step are sequentially executed through a Z-axis accurate-rough grinding device; and unprocessed glass panels or rear glass cover plates sequentially pass through the clamping and positioning step, the rough grinding step, the main-axis forming step and the accurate grinding step and then respectively form formed glass panels or rear glass cover plates. According to the 2.5 D forming process method of glass panels or rear glass cover plates, the glass panels or rear glass cover plates are clamped and positioned for only one time, the processing quality and the processing efficiency of the formed glass panels or rear glass cover plates can be simultaneously ensured, the processing cost is also reduced, and the using demands of users are met.

Description

technical field [0001] The invention relates to the field of 2.5D cold processing technology for glass plates, in particular to a 2.5D forming process method for glass panels or glass rear covers that can be used in the fields of mobile phones, tablet computers, game machines and the like. Background technique [0002] There are mainly two traditional 2.5D molding processing methods for glass panels or glass back covers. Among them, the first processing method is: first, use a CNC grinder or a manual positioning grinder to process the unprocessed glass panel and glass back cover. Carry out cold processing (that is, horizontal axis grinding) to form 2.5D glass panel blanks and 2.5D glass back cover blanks respectively, and then use other equipment to process the 2.5D glass panel blanks and 2.5D glass back cover blanks. The blank of the cover plate is subjected to operations such as shape processing, edge chamfering, and polishing, and finally forms a shaped glass panel and a ...
