Description

Technical Field

[0001] The invention relates to an electronic glass online cleaning device and method. Background Art

[0002] Electronic glass generally refers to ultra-thin float glass with a thickness of 0.1~2mm. It refers to a type of high-tech product that can be used in the fields of electronics, microelectronics, and optoelectronics. It is mainly used to make integrated circuits and glass materials with photoelectric, thermoelectric, acousto-optic, magneto-optic and other functional components. Electronic glass is most widely used in smartphones and tablets. According to the structure of the mobile phone screen, it is mainly divided into two types of glass: cover glass (window protective glass) and substrate glass.

[0003] Cover glass (window protective glass) is a transparent lens added to the outside of the display screen to protect the touch module and display module. Its inner surface must be able to fit tightly with the touch module and display screen, and its outer surface must have sufficient strength to protect the flat screen, touch module, etc., as well as product identification and decoration functions. It is an important component of consumer electronic products and is widely used in mobile phones, tablet computers, laptops, desktop computers, digital cameras, players, GPS navigators, automotive instruments and other products. Cover glass is a highly customized product with high processing precision, high process difficulty, and a comprehensive application of multidisciplinary technologies.

[0004] During the processing of cover glass, in order to avoid scratches and other defects of electronic glass during the complicated cold processing, a layer of protective ink of about 0.015-0.03mm needs to be applied on the surface of the glass. The process flow is: coating protective ink → cutting → CNC → one-time cleaning → 2.5D scanning → de-inking and cleaning → strengthening → post-processing.

[0005] For ordinary untreated glass, the protective ink is easy to fall off during CNC, one-time cleaning, and 2.5D scanning. After analysis and verification, the water drop angle of the untreated glass test is too large, that is, the glass is not hydrophilic enough and the surface tension is too large, which is reflected in the mismatch between the liquid protective ink and the surface tension of the glass, and the insufficient adhesion after UV curing. In the post-processing process, the protective ink falls off due to the erosion and softening of CNC coolant and cleaning agents, cleaning ultrasound, scanning and polishing and other external factors. After the ink falls off, it will cause the surface of the glass to be scratched. This problem affects the product quality and yield of the downstream cover processing plant. The downstream customers traced this problem back to the supplier of cover glass raw materials. After repeated demonstration, the supplier of raw materials concluded that the ink falling problem is closely related to the sulfur dioxide film on the surface of the glass. Because the sulfur dioxide film on the surface increases the tension of the glass surface, the tension of the glass surface increases, which affects the adhesion of the ink on the glass surface, resulting in ink falling off during the processing, resulting in a large number of scratches on the glass surface. To solve this problem, the specific plan is to reduce the use of sulfur dioxide. However, after reducing the use of sulfur dioxide, the glass is easily scratched. After research and testing, an intelligent cleaning line is added to the electronic glass production line. After washing off the sulfur dioxide film on the surface of the glass, PE film is immediately applied to the upper and lower surfaces of the glass, which effectively solves this problem.

[0006] In order to meet customer quality requirements, it is necessary to add a cleaning line. Ordinary offline cleaning lines have high labor costs, low efficiency, and are prone to quality problems. Summary of the invention
