Mobile phone 3D glass positioning and processing system and method

Abstract

The invention relates to the technical field of mobile phone manufacturing and processing, and discloses a mobile phone 3D glass positioning processing system, including a CNC machine tool head, a probe and a CNC machine tool control unit. The mobile phone 3D glass is fixed on the processing table, and the probe is installed on the CNC machine tool. On the head, determine at least three thickness measurement positions on the surface of the 3D glass of the mobile phone. The control unit of the CNC machine tool controls the probe to probe at the thickness measurement position to obtain the average thickness of the 3D glass surface of the mobile phone and determine the processing amount. On the side of the 3D glass of the mobile phone Determine at least two positions in the edge direction, the control unit of the CNC machine tool controls the probe to detect the position in the direction of the edge, obtains the boundary line of the 3D glass of the mobile phone and determines the processing path, and the control unit of the CNC machine tool performs decrement machining according to the processing amount and the processing path . The invention also discloses a processing method using the above system. The invention makes the edge of the 3D glass smoother and rounder, and increases the precision and strength of the product.

Description

technical field [0001] The invention relates to the technical field of mobile phone manufacturing and processing, in particular to a mobile phone 3D glass positioning processing system and processing method. Background technique [0002] At present, in the global mobile phone industry, 2.5D curved glass continues to be popularized, and the development of 3D curved screen mobile phones has also started. 3D curved glass has the advantages of being light and thin, transparent and clean, anti-fingerprint, anti-glare, hard, and scratch-resistant. The control function brings excellent touch feel and wireless charging function. Due to the differentiated appearance and popular demand for wireless charging, 3D glass back covers will gradually replace metal back covers as the choice of mainstream smartphone brands, and the demand for 3D cover panels will explode. The competition for 3D covers will be more exciting, and the quality requirements for 3D covers will be higher. [0003]...

AI Technical Summary

Problems solved by technology

Due to unstable factors such as the length of the brush, the concentration of the sweeping powder, and the pressure of the sweeping machine, the sweeping machine cannot accurately calculate the grinding amount like CNC machining, so the sweeping will also seriously affect the size of the product

[0008] To sum up, the current hot-bending 3D glass products in the industry generally have problems such as large dimensional tolerances, inconsistent product heights, resulting in gaps in assembly, low strength, and fragility.
