Problems solved by technology

However, OGS products will not be effective unless high-adhesive tape with strong adhesion is used. However, if high-adhesive tape is used, it is difficult to peel off the attached tape after water jet processing, and it is easy to damage the touch panel sensor.
If the surface is coated with resin and then cut by water jet, solvent must be used to peel off the resin after cutting. The condensation caused by solvent and solvent will make the surface dirty or damaged

Embodiment 1

[0026] Use low-viscosity UV curing, warm water or special stripping liquid to peel off the resin, paste thin glass plates on both sides of OGS chemically strengthened large glass, or process thin resin plates that can pass through UV, then use warm water or special stripping liquid Perform stripping.

[0027] First, drop a low-viscosity UV-curable resin (viscosity below 1000mPa·s) on one side of OGS chemically strengthened large glass, and then press and bond it with a thin glass plate (thickness 0.03-0.7mm), or use UV-permeable The resin plate (thickness is 0.03 ~ 0.7mm) is pressure-bonded, so that the resin is evenly coated on the OGS chemically strengthened large glass and cured by ultraviolet radiation. The other side of the large sheet of OGS chemically strengthened glass is also processed in the same process, using a thin glass plate (thickness 0.03-0.7mm) for pressure bonding, or a resin plate (0.03-0.7mm) that can transmit ultraviolet rays (0.03-0.7mm). Combine to sol...

Embodiment 2

[0032] Use low-viscosity UV-cured, warm water or resin stripped by special stripping liquid, paste UV-permeable thin plate on one side of OGS chemically strengthened large glass plate with low-viscosity resin for curing, and paste UV-impermeable thin plate on the other side for curing , Peel off with warm water or a special stripping solution.

[0033] Drop a low-viscosity UV-curable resin (below 1000mPa·s) on the OGS chemically strengthened large glass, and then use a thin metal plate or resin plate (0.03-0.7mm) that cannot pass through UV to press and bond the resin to make the resin in OGS chemically strengthened. It is evenly coated on a strengthened large sheet of glass and cured by UV light. On the other side of the OGS chemically strengthened large glass, the same process is followed, dripping resin, and using a thin glass plate (thickness 0.03-0.7mm) or a resin plate (0.03-0.7mm) that can pass through ultraviolet rays. After both sides are bonded and cured, the OGS ch...

Embodiment 3

[0038] Use a low-viscosity resin on the bottom of the glass to paste a thin plate for curing (it can be a UV-transparent or impermeable thin plate, a thin glass plate, or a thin metal plate, or a thin resin plate), and paste a UV peeling on the upper part of the glass Adhesive tape protection.

[0039]Drop low-viscosity UV-curable resin (below 1000mPa·s) on the bottom of OGS chemically strengthened large glass, and then use a thin glass plate with a thickness of 0.03-0.7mm, or a thin metal plate, or a thin resin plate to press and bond the resin. Spread evenly on a glass substrate and cure by UV irradiation. After the UV peeling adhesive tape is pasted on the upper part of the OGS chemically strengthened large glass, the OGS chemically strengthened large glass is cut with a water jet. After the cut single OGS glass is irradiated with UV, the adhesive tape will fall off, and then warm water (40 -95°C) or soaked in a special stripping solution, the thin glass and UV curable res...

Abstract

The invention discloses a processing method for integrated cover plate glass of a touch sensor, which comprises the steps of: Step 1, uniformly dropping low-viscosity ultraviolet curable resin onto a large OGS (one glass solution) chemically strengthened glass plate, pressing with a sheet for adhesion, and irradiating with ultraviolet rays for curing; Step 2, cutting the large OGS chemically strengthened glass plate into single OGS glass pieces in a water jet cutting method; and Step 3, soaking the single OGS glass pieces in warm water or dedicated stripping solution, and removing the resin and the sheet. By adopting the processing method for the integrated cover plate glass (OGS) of the touch sensor, the defect that cutting scars on the outlet side are more serious than cutting scars on the inlet side during water jet processing can be overcome, the hard sheet is used as a protective layer on the outlet side during water jet processing, the cutting scars can be greatly improved, no corrosion and damage can be caused to the touch sensor, a black frame and substrate glass, and the quality of the single OGS glass pieces can be well protected after cutting.

Description

technical field [0001] The invention relates to a method for cutting and processing touch screens of electronic products, in particular to a processing method for integrated cover glass (OGS) of touch sensors used to protect display screens of mobile phones, electronic notepads, tablet computers, personal computers, and game machines method. Background technique [0002] Electronic portable terminal products such as mobile phones and PDAs are equipped with cover glass to prevent the display screen from being impacted by external forces. As these portable products are becoming lighter and thinner, a design scheme integrating cover glass and touch sensor, that is, OGS (one glass solution) scheme, has appeared in the market. This solution uses high-strength chemically strengthened thin glass to make the cover glass, and the sensor that drives the product is arranged on the inner layer. For the convenience of processing, many small pieces of OGS are made on a large piece of ch...
