Abstract
The invention discloses a thinning agent for a rear cover of a glass mobile phone, compared with the prior art, the rear cover of the glass mobile phone is produced, a hole site (2) for mounting a camera is arranged on the rear cover (1) of the glass mobile phone, a protective cover (6) for protecting the camera is arranged on the hole site (2), the protective cover (6) and the hole site (2) are fixedly connected in a seamless mode or are integrally formed, reinforcing ribs (3) which are fixedly connected are arranged on four corners and four sides of the rear cover (1) of the glass mobile phone, the reinforcing ribs (3) and the rear cover (1) of the glass mobile phone are fixedly connected in a seamless mode or are integrally formed, the rear cover (1) of the glass mobile phone comprises two layers or multiple layers of plane glass (4), a protective layer (5) is arranged on the plane glass (4), and the two layers or multiple layers of plane glass (4) are attached together through a bonding process. The glass mobile phone rear cover thinning agent solves a series of problems of a glass mobile phone rear cover made of a mobile phone shell rear cover thinning agent.
Description
Technical Field
The invention relates to the field of rear cover manufacturing of glass mobile phones, in particular to a rear cover thinning agent for a glass mobile phone.
Background
At present, the materials used by the existing mobile phone rear cover are generally glass, ceramics, metal and plastics. However, with the rise of wireless charging and 4G and 5G materials, metals cannot perform wireless charging and 4G and 5G signal transmission due to shielding of electromagnetic waves, and are gradually eliminated. Ceramics and glass have a large specific gravity, but ceramics are fragile, and conventional flat glass is increasingly unable to meet people's needs. Because along with cell-phone curved surface glass more and more general, for example camera function's reinforcing, local boss has appeared in the lid behind the cell-phone, continues corresponding back lid and satisfies high definition image and laser radar scanner's demand.
However, the existing thinning process for the rear cover of the traditional mobile phone is mainly CNC engraving and molding, the whole glass is subjected to processes such as shape material removal, polishing and strengthening through CNC to obtain the rear cover of the mobile phone, the CNC is long in processing time and low in manufacturing efficiency, and the processed flatness is far lower than that of flat grinding. And when CNC processing local boss, the plane of newly producing can produce a large amount of crazing lines, fish tail, reduces glass's intensity, near boss especially corner region, because need a lot of break bars vestige concatenation to form, consequently can a lot of break bars vestige. Moreover, when the CNC processes the local convex table, non-planar polishing is needed, which not only has low polishing efficiency, but also the concave area is difficult to polish, the glass yield and strength are reduced, and the flatness and thickness uniformity are far inferior to those of the flat grinding process because of the use of the non-planar polishing. Moreover, the edge of the rear cover of the glass mobile phone is not protected, so that the rear cover is easy to damage in the installation process.
Meanwhile, hydrofluoric acid is mostly adopted in the traditional mode for glass corrosion. Hydrofluoric acid corrosion glass is a highly toxic and volatile chemical as a traditional glass thinning scheme, and has strong irritation and corrosivity on skin. The hydrogen ions in hydrofluoric acid have dehydrating and corrosive effects on human tissues, and fluorine is one of the most active nonmetallic elements. After the skin is contacted with hydrofluoric acid, fluorine ions are continuously dissociated and permeate into deep tissues to dissolve cell membranes, so that liquefaction and necrosis of epidermis, dermis, subcutaneous tissues and muscular layers are caused. Fluorine ions can also interfere the activity of enolase to inhibit the oxygen uptake capacity of skin cells, and people can immediately die after taking about 1.5g of hydrofluoric acid, and inhale high-concentration hydrofluoric acid mist to cause bronchitis and hemorrhagic pulmonary edema. Hydrofluoric acid can also be absorbed through the skin causing severe poisoning.
Therefore, the conventional etching of glass with hydrofluoric acid has at least the following problems: (1) hydrofluoric acid process is a national policy restriction class, and the environmental evaluation is difficult to criticize; (2) the equipment investment is large, and sealed negative pressure equipment is needed for preventing hydrofluoric acid from leaking when the hydrofluoric acid is thinned; (3) the workshop safety risk is large, the maintenance cost is high, and because hydrofluoric acid is colorless and odorless, a sensor needs to be installed at a key position of the workshop to monitor the content of the hydrofluoric acid in real time; (4) the hydrofluoric acid is dangerous waste after corroding the glass, and the treatment cost is high; (5) hydrofluoric acid is a highly toxic substance, and has a great safety risk in transportation.
