Processing method of lamination and cutting of touch screen

Abstract

The invention discloses a processing method of lamination and cutting of a touch screen. The method comprises the following steps: step 1, a process of lamination; step 2, a process of cutting; and step 3, a process of separation. According to the processing method of lamination and cutting of the touch screen, operation of protecting upper and lower surfaces of the touch screen with a resin adhesive tape or bonding and laminating the upper and lower surfaces with a resin is not needed, and an entire supporting and absorbing jig, the size of which is completely same as that of a cut product, is customized. The rigidity of supporting laminated glasses is improved during a cutting process, and the cut scar and edge breakage is controlled in an optimum range. Glasses are fixed through an upper pressing fig, so that separation and transportation of the glasses during punching or cutting are avoided. When a cutting graph is a closed ring, half of cutting is carried out; the upper pressing jig is shifted and is positioned at the previous cutting terminal; and the other half of cutting is carried out. According to the processing method, no other process of laminating a bonding resin and protecting the surfaces by coating with a resin is needed. The processing method is high in efficiency and in high-class product ratio, low in cost, and simple in process.

Description

technical field [0001] The present invention relates to the cutting and processing method of optical glass and touch screen glass of consumer electronic products, in particular to a processing method of cover glass used for protecting display screens of mobile phones, electronic notepads, tablet computers, personal computers, game machines, etc. method. Background technique [0002] Electronic portable terminal products such as mobile phones and tablet computers are equipped with protective cover glass to prevent the display screen from being impacted by external forces. As these portable products are becoming lighter and thinner, in order to improve production efficiency and ensure the final processing yield of products, high-quality ordinary optical glass and surface chemically strengthened glass will be used for processing. It is not easy to cut high-quality ordinary optical glass and surface chemically strengthened glass for special-shaped lamination without any adhesiv...

Problems solved by technology

Adhesive tapes, smearing protective resins, and lamination operations using resins on existing product substrates all require additional equipment and increased process flow, resulting in instability in productivity and production yield for hard and brittle glass products

[0004] In particular, if adhesive tape, coating of protective resin, and resin lamination are carried out on the product substrate, and then processed by particle cutting, the resin must be peeled off with a solvent after cutting, and the condensation caused by the solvent will cause the surface to have dirty or damaged

[0005] The non-adhesive resin laminated particle cutting method mainly has the following disadvantages: first, the abrasives impacted by the high-pressure jet are easy to damage the glass surface; When cutting, the high-pressure jet of abrasive water and airflow will cause separation and displacement of the glass; thirdly, when the product is cut with a special-shaped closed figure without any adhesive resin laminated products, the high-pressure jet of abrasive water or airflow will be at the end When the knot is formed, because the abrasive jet has a deformed cutting area on the lower end of the product, the laminated upper end product is cut first, and the upper end product is not bonded to the fixed bottom glass product in any way, so the high-pressure jet abrasive Water flow or air flow will cause separation and displacement of the upper glass; Fourth, during the cutting process, the large glass substrate is placed horizontally, and the particle cutting device is sprayed and cut vertically from top to bottom. The side will cause cutting scars, especially the bottom cutting scars on the outlet side of the lower end of the abrasive cutting are more serious than the upper inlet side; fifth, due to the high-pressure jet of abrasive water flow or air flow, there will be deformation in the cutting area at the lower end, because the glass is not enough Rigidity, so under the pressure of high-pressure jet abrasive water flow or air flow, it will vibrate, resulting in the reduction of processing accuracy and large chipping of glass.
