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 will be difficult to peel off the attached tape after water jet processing, and the touch panel sensor will be easily damaged.
[0006] Especially, if the surface is coated with resin and then cut by water jet, after cutting, solvent must be used to peel off the resin, and the condensation caused by solvent and solvent will make the surface dirty or damaged

Embodiment 1

[0039] On both sides of the OGS chemically strengthened large glass, use a screen printing machine or other equipment to evenly print UV curable resin on both sides of the glass. After printing, use UV radiation to cure the resin, and then cut the OGS chemically strengthened large glass with a water jet. After the single OGS glass is soaked in warm water, the UV curable resin printed on its surface can be easily peeled off. The touch sensor, black frame, and glass substrate will not be discolored or damaged, and the scratches caused by water jet cutting are improved. The parameters of the ultraviolet curable protective resin are: thickness: 0.005-0.1 mm, Shore hardness above A60. The table below shows a comparison of the 2 resins.

[0041] After the printing resin is cured, the water jet cuts the large piece of OGS chemically strengthened glass. Comparing the scars after water jet cutting, it is found that the water jet is sprayed against the initial side (inlet) ...

Embodiment 2

[0043] On the large sheet of OGS chemically strengthened glass, use equipment such as a screen printing machine to evenly print UV curable resin on both sides of the glass. After printing, irradiate the resin with ultraviolet rays to cure the resin, and then cut the large sheet of OGS chemically strengthened glass with a water jet. After cutting The UV curable resin printed on the surface can be easily peeled off by soaking a single OGS glass with a special stripping solution (C-130). The touch sensor, black frame, and glass substrate will not be discolored or damaged, and the scratches caused by water jet cutting are improved.

Embodiment 3

[0053] Prepare adhesive tapes of the same size as the large glass on both sides of the OGS chemically strengthened large glass, and use a laminator to stick the adhesive tape on the large glass and press it tightly. After bonding, cut and dry OGS chemically strengthened large sheets of glass with a water jet. The adhesive tape on the cut single OGS glass was irradiated with ultraviolet light and the adhesive tape was peeled off. UV exposure: 300mj / cm ２ . In this way, the touch sensor, black frame, and glass substrate will not be discolored or damaged. Scars after water jet cutting are also improved. The parameters of the ultraviolet peeling and sticking tape used are: substrate film thickness: 0.05-0.2mm, sticking layer thickness: 0.01-0.05mm, and Shore hardness above A60. The following table is a comparison of several tapes.

Abstract

The invention discloses a cutting processing method of a touch screen. The method comprises the steps that: a hard and thick adhesive tape is adopted, or resin is used as a protective layer and is applied on OGS chemically enhanced large-piece glass; the OGS chemically enhanced large-piece glass is cut into single OGS glass sheets by using water jet; and the adhesive tape or the resin is peeled. According to the processing method provided by the invention, no corrosion or damage is caused upon touch sensors, black border frames, and substrate glass; damages caused by water jet cutting can be reduced, and the qualities of the cut single OGS glass sheets can be well protected.

Description

technical field [0001] The invention relates to a touch screen cutting processing method for electronic products, in particular to a processing method for integrally cutting cover glass and touch sensors used to protect display screens of mobile phones, electronic notepads, tablet computers, personal computers, and game machines. 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 chemically stre...
