A method of manufacturing a chemically tempered thin glass using a full automated thin glass grinding machine with separated multi spindles and an apparatus for the same

Abstract

An automatic machining device with multiple separated spindles for a thin sheet glass and a manufacturing method of a tempered glass using the same are provided to minimize non-uniform chipping, stress, and fine cracks caused by the deterioration of glass. CONSTITUTION: An automatic machining device(100) with multiple separated spindles for a thin sheet glass comprises a multi-shape supply unit(110), a multi-shape positioning unit(120), a horizontally moving and automatically aligning unit(130), and a multi-spindle grinding unit(140). The multi-shape supply unit supplies glasses to the multi-shape positioning unit. The multi-shape positioning unit determines the position of the supplied glasses. The horizontally moving and automatically aligning unit automatically aligns pallets(150) in which the glasses are positioned. The multi-spindle grinding unit is composed of multiple machining spindle assemblies for machining the glasses.

Description

technical field [0001] The present invention relates to a thin plate glass processing device and a tempered glass manufacturing method using the above device, and more particularly to processing the shape and interior of the outer peripheral surface before tempering in order to manufacture tempered glass for external display of portable electronic devices and home electronic devices using thin plate glass A multi-axis separation automatic thin-plate glass processing device in the shape of holes, slots, top and bottom chamfering, etc., and a tempered glass manufacturing method using the above-mentioned device. Background technique [0002] Generally speaking, when cutting or beveling the surface of thin plate glass, it is placed on an adsorption machine and rotated at a constant speed while contacting a diamond blade to complete grinding. [0003] figure 1 It is a schematic diagram of the NC (Numerical Control) device 1 composed of four axes. [0004] The glass processing o...

Problems solved by technology

After the surface cutting is completed, each edge is beveled, but due to the difference in processing shape and process, the continuity of the setting operation of workers and diamond blades cannot be ensured, and the production speed is slow. Therefore, it takes a lot of time to increase productivity. high cost

[0005] In addition, using the thin plate glass shape processing method imitating the cam method, there is a deviation of more than ±100° in the accuracy of the processing size. Therefore, the accuracy deviation of the processing size that cannot meet the level required for tempered glass today needs to be less than ±50°. However, the shape processing method of thin plate glass using glass etching technology requires additional fine grinding of the cut surface after etching the cut shape, so that the operation time is long and the cost becomes high.

[0006] In addition, using the method of the NC device of the prior art, processing such as coarse grinding, semi-fine grinding, fine grinding, holes, and slots is performed on the same fixed table, so uneven chipping (chipping) and pressure caused by glass deterioration Stress and fine scratches will cause the overall strength of the display window and the decline in quality, and there is a danger of the operator being injured by the grinder during the operation
