Description
Technical Field
The invention belongs to the technical field of ultra-thin glass processing, and particularly relates to a UTG glass edge processing method.
Background

With the development and innovation of 5G technology, folding screen mobile phones have begun to be introduced into the market and become an emerging mobile phone development trend. The folding screen mobile phone generally adopts ultrathin flexible glass (UTG glass) with the thickness of less than 0.2 mm, and the ultrathin flexible glass (UTG glass) has higher performance indexes in the aspects of surface flatness, scratch resistance, high temperature resistance, impact protection on display screen devices and the like, and can still restore the original flatness after being repeatedly bent for a long time.
Ultrathin flexible glass is usually cut and typed by laser or knife wheel to form small units with different sizes and specifications applicable to different products. The laser cutting has the characteristics of high precision, good environmental protection, low loss, high stability and the like, but when the laser is used for cutting glass, the bad defects of the glass edge caused by the heat radiation of the laser still exist, such as roughness, saw teeth or microcracks on the cutting surface caused by the heat effect of the laser; and the splinter after laser cutting can cause edge breakage at the cutting position. Compared with laser cutting, the cutter wheel cutting has the processing characteristics of high efficiency and low cost, but the cutter wheel cutting cannot be directly molded, the cracking is difficult, the glass surface is easy to scratch, and the cutting surface has the defects of serious edge breakage, saw teeth, microcracks and the like. When the glass is bent, defects such as cracks in the cut surface may develop due to stress concentration, and the glass may be broken. In order to improve the folding quality of ultrathin glass, the edges of the glass are generally polished by adopting a chemical etching process so as to eliminate defects such as microcracks formed in the cutting process of the edges of the glass and avoid the response of the microcracks in the folding processStress cracking due to force concentration. The maturity of the chemical etching process is high, but FH and H are used in a large amount 2 SO 4 、HNO 3 Strong acids such as HCL cause serious pollution to the environment and have great influence on the physical health of personnel.

Optionally, the outer edge of the mounting plate 2 coincides with the outer edge of the UTG glass plate 1, or the outer edge of the mounting plate 2 protrudes beyond the outer edge of the UTG glass plate 1.
In S500, the grinding unit may be controlled to rotate by the clamping device, so that the grinding fluid 401 may be sprayed on each side of the grinding unit, or the grinding fluid 401 may be sprayed along the outer periphery of the grinding unit.
Alternatively, the mounting sheet 2 is a glass member.
In some embodiments, referring to fig. 1 to 5, after S500, the method further includes:
s600, taking out the polishing unit from the clamping device, then placing the polishing unit in the ink 3 cleaning solution, separating the mounting sheet 2 from the UTG glass sheet 1 after the ink 3 is dissolved, and taking out the UTG glass sheet 1;
and S700, cleaning the taken UTG glass sheet 1, drying the cleaned UTG glass sheet 1, and packaging.

In some embodiments, referring to fig. 1 to 5, in S100, the thickness of the ink 3 is not less than 30 μm.
Too thin a thickness of the ink 3 is not beneficial to separating two adjacent UTG glass sheets 1, and too small an interval between two adjacent UTG glass sheets 1 can cause that the grinding fluid 401 cannot smoothly enter the retention space 301, so that normal grinding of the UTG glass sheets 1 is affected.
In some embodiments, referring to fig. 1 to 5, S100 specifically includes:
s110, cutting and parting the formed UTG glass to form a plurality of UTG glass sheets 1;
s120, cleaning and drying the UTG glass sheet 1, and removing impurities such as dust on the surface of the UTG glass sheet 1;
and S130, respectively brushing the ink 3 on two sides of the UTG glass sheet 1 after cleaning and drying.
During the cutting process, the cut UTG glass sheet 1 produced glass dust, which adhered to the surface of UTG glass sheet 1, and the dust on the surface of UTG glass sheet 1 was removed by washing, and then dried to form a clean UTG glass sheet 1, and then ink 3 was applied to UTG glass sheet 1. Avoiding the surface scratch of UTG glass sheets 1 caused by glass dust when the ink 3 is coated or after the adjacent UTG glass sheets 1 are overlapped.
In some embodiments, referring to fig. 1 to 5, the grinding fluid 401 in S500 is a cerium oxide suspension.
The polished UTG glass sheet 1 has higher edge finish due to higher hardness and abrasive properties of the cerium oxide. The chemical property of the cerium oxide ensures that the compound generated with the UTG glass sheet 1 has higher stability and wear resistance in the polishing process, and further improves the polishing quality of the glass surface.
In some embodiments, referring to fig. 1 to 5, in S500, the grinding fluid 401 is continuously sprayed to the outer circumference of the grinding unit so that the outer circumference of the grinding unit is always covered with the grinding fluid 401 until the edge of the UTG glass sheet 1 is ground to a preset thickness.
The grinding fluid 401 flows along the circumferential direction in the reserved space 301, so that the edge of the UTG glass is polished, but along with the flow of the grinding fluid 401, part of the grinding fluid 401 flows out of the reserved space 301 under the action of gravity, so that the grinding fluid 401 needs to be continuously supplemented until the UTG glass is polished circularly and reaches the preset thickness.
In some embodiments, referring to fig. 1-5, in S500, the edge of the polished UTG glass sheet 1 is rounded 302 to make the edge thickness of the UTG glass sheet 1 less than the thickness of the middle portion of the UTG glass sheet 1.
The rounded chamfer 302 reduces the sharp corners at the edge of UTG sheet 1 and reduces the chance of chipping in the stress at the edge of UTG sheet 1.
In some embodiments, referring to fig. 1-5, in S300, the thickness of UTG glass sheet 1 is less than the thickness of mounting sheet 2.
The thickness of the mounting sheet 2 is greater than the thickness of the UTG glass sheet 1, thereby increasing strength and avoiding cracking of the mounting sheet 2 when mounted with clamping equipment.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
