Problems solved by technology

After the cover glass is strengthened, the impact resistance test, the general industry standard is that a 130g steel ball is broken at 30 cm, and the impact resistance test uses a drop frame. The falling ball passes through a plastic tube and impacts the glass at a height of 20 cm. The product is not damaged, and each time it is 5 cm high. Incremental, until the glass is broken, the original process of impact resistance test can only do 40cm without breaking, using the existing cover glass processing technology to process the glass cover with low strength and short service life

Embodiment Construction

[0009] Below in conjunction with the examples, the specific implementation of the present invention will be further described in detail. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0010] An impact-resistant production process for cover glass, comprising the following steps:

[0011] 1) Use a cutting machine to cut the white glass, and then carry out CNC forming processing to process it into cover glass;

[0012] 2) The cover glass treated in step 1) is 100% polished by a polishing machine, and the polished cover glass is fully inspected and then strengthened;

[0013] 3) The cover glass treated in step 2) is 100% finely polished by a polishing machine for 15 minutes, and the good products detected after the fine polishing are tested for falling ball impact resistance.

[0014] The impact-resistant production process of the cover glass of the present invention is to increase the impa...

Abstract

The invention relates to a cover board glass impact resistance production process. The process includes the following steps that firstly, a cutting machine is adopted for cutting white glass, CNC forming is performed, and the glass is processed into cover board glass; secondly, the cover board glass processed through the first step is polished 100% through a polishing machine, the polished cover board glass is checked to be qualified and then strengthened; thirdly, the cover board glass processed through the second step is precisely polished 100% through the polishing machine for 15 minutes, and after precise polishing is finished, qualified products obtained through checking are subjected to impact resistant tests. By the adoption of the cover board glass impact resistance production process, 100% polishing and 100% precise polishing are added, the precise polishing time is 15 minutes, and the impact resistance is improved to a great extent through full polishing and precise polishing procedures; and the original condition that the glass can resist to a steel ball of 130 g at a distance of 30 cm is changed into the innovative condition that the glass can resist to the steel ball of 130 g at a distance of 70 cm.

Description

technical field [0001] The invention relates to an impact-resistant production process of cover glass. Background technique [0002] At present, the production of cover glass used in mobile phones, tablet computers, etc. generally adopts the following process: clear glass cutting-CNC molding-polishing (30%)-inspection-strengthening-functional testing-clear glass inspection. After the cover glass is strengthened, the impact resistance test, the general industry standard is that a 130g steel ball is broken at 30 cm, and the impact resistance test uses a drop frame. The falling ball passes through a plastic tube and impacts the glass at a height of 20 cm. The product is not damaged, and each time it is 5 cm high. Incrementally, until the glass is broken, the original process of impact resistance drop ball test can only do 40cm without breaking, and the glass cover processed by the existing cover glass processing technology has low strength and short service life.
