Glass mobile phone front cover thinning process

Abstract

The invention discloses a glass mobile phone front cover thinning process, which is characterized in that compared with the existing glass mobile phone front cover, the produced glass mobile phone front cover (1) is provided with a hole site (2) for mounting a camera, a protective cover (6) for protecting the camera is arranged on the hole site (2), and the protective cover (6) and the hole site (2) are seamlessly and fixedly connected or integrally formed. The four corners and four edges of the glass mobile phone front cover (1) are provided with fixedly connected reinforcing ribs (3), the reinforcing ribs (3) and the glass mobile phone front cover (1) are seamlessly and fixedly connected or integrally formed, the glass mobile phone front cover (1) comprises two or more layers of plane glass (4), the plane glass (4) is provided with a protective layer (5), and the protective layer (5) is provided with a protective layer (6). The two or more layers of plane glass (4) are attached together through a bonding technology. A series of problems existing in a glass mobile phone front cover manufactured by a mobile phone shell front cover thinning process are solved.

Description

technical field [0001] The invention relates to the field of glass mobile phone front cover manufacturing, in particular to a thinning process for the glass mobile phone front cover. Background technique [0002] At present, the materials used for the existing front covers of mobile phones are generally glass, ceramics, metals and plastics. However, with the rise of wireless charging and 4G and 5G materials, metals will shield electromagnetic waves, making wireless charging and 4G and 5G signal transmission impossible, and are gradually being phased out. Ceramics and glass have a large proportion, but ceramics are fragile, and conventional flat glass is increasingly unable to meet people's needs. Because as the curved glass of mobile phones is becoming more and more common, such as the enhancement of camera functions, the front cover of the mobile phone has a local boss, and the corresponding front cover continues to meet the needs of high-definition images and lidar scanne...

Problems solved by technology

At present, major mobile phone operators are scrambling to release folding screen mobile phones. At present, the mainstream hard thick cover glass mobile phone front cover (thickness is 0.1mm-1.0mm) cannot be bent, and it is no longer suitable for folding screen mobile phones, only 0.005mm -0.100 mm thickness of the glass front cover of the mobile phone can meet the requirements of the folding screen

The existing mature glass mobile phone front cover molding process can only obtain a thickness of 0.05mm-2.0mm, and to meet the needs of folding screen mobile phones, it is necessary to use a thinning process to reduce the thickness to 0.005mm-0.100mm

[0005] When the front cover of the glass mobile phone is thicker, the rigidity and strength of the glass mobile phone front cover (0.05mm-2.0mm thickness) are good, but when the glass mobile phone front cover gradually becomes thinner, the rigidity and strength of the glass mobile phone front cover will decrease. The sharp drop caused the following problems to occur in the thinning process of the front cover of the glass mobile phone: (1) When the front cover of the glass mobile phone is cleaned, because the strength of the front cover of the glass mobile phone is reduced, when cleaning, including but not limited to water washing, air bubbles, wind blowing, etc. During the process, when the impact force in the process is greater than the strength of the front cover of the glass mobile phone, the front cover of the glass mobile phone is easy to break

When the impact force is too small, the surface of the front cover of the glass mobile phone will not be cleaned cleanly, and the foreign matter will cause defects on the surface of the front cover of the glass mobile phone during the thinning process, resulting in defects such as the strength, appearance, and display module abnormality of the front cover of the glass mobile phone.

(2) When the front cover of the glass mobile phone is thinned, the self-weight of the front cover of the glass mobile phone at the contact position of the bracket causes the stress of the front cover of the glass mobile phone to exceed the strength of the front cover of the glass mobile phone, and the front cover of the glass mobile phone is easy to break

Although it can be solved by increasing the contact area between the front cover of the glass mobile phone and the bracket, increasing the contact area between the front cover of the glass mobile phone and the bracket during the thinning process will enlarge the shelf print on the contact part of the front cover of the glass mobile phone, causing poor appearance

(3) When the front cover of the glass mobile phone is thinned, it is necessary to use auxiliary methods such as bubbling or ultrasound. Bubbling or ultrasound will aggravate the expansion of micro-cracks on the surface of the front cover of the glass mobile phone. The front cover of the glass mobile phone is getting thinner and thinner, and micro-cracks are easy Extending to the thickness of the entire glass phone front, thin glass phone fronts are easily cracked

(4) The rigidity of the front cover of the glass mobile phone is reduced. When the front cover of the glass mobile phone is taken and placed, the front cover of the glass mobile phone will deform rapidly due to its own weight at the position where it contacts the front cover of the glass mobile phone. When the deformation exceeds the allowable range of the front cover of the glass mobile phone, the glass The front cover of the phone will crack
