Improved sticking touch control panel body and manufacture method thereof

Abstract

The invention discloses an improved sticking touch control panel body and a manufacture method thereof, belonging to the technical field of sticking procedures for manufacturing touch control panel bodies. Release paper is rapidly torn at one step by adopting a large double sticky tape as a sticking medium and mounting a plurality of sticking pattern units formed by connecting sections, and the surface of a semi-finished product after all touch control panel bodies are cut and a soft transparent film are integrally moulded; and the great improvement of productivity, manufacture efficiency and quality qualified rate is realized in the most important sticking procedure.

Description

technical field [0001] The invention relates to an improved and bonded touch panel body and a manufacturing method thereof, which belong to the technical field of bonding process for making a touch panel body. Background technique [0002] With the rapid development of science and technology, touch screen products, as the simplest, most convenient and natural way of human-computer interaction, endow multimedia with a brand-new look and are extremely attractive new multimedia interactive devices. At present, the touch panel lamination process uses conductive film or conductive glass substrate screen printing water glue as the bonding interface, and then conducts conductive film and conductive glass substrate lamination, but the water glue may overflow under strict environmental tests Appear. Therefore, under high-quality environmental resistance tests, touch panels have adopted high-viscosity double-sided tapes as the bonding interface between the conductive glass substrate ...

AI Technical Summary

Problems solved by technology

Double-sided adhesive tape lamination methods are different. If manual single-piece lamination has the following disadvantages: 1. Low output, 2. High labor cost, 3. High defect rate, etc., it is necessary to make a large-scale lamination process to overcome manual single-piece Due to the shortcomings of bonding, there are usually two technical solutions for designing the adhesive pattern unit pattern on a large double-sided tape as follows:

[0003] Option 1: Cut each adhesive pattern unit according to the size of the action area of ​​the touch panel and remove the tape to form a plurality of cavities, leaving double-sided adhesive tape connected outside the action area. Technical disadvantages of Option 1: 1. Fragments It is not easy. When cutting the conductive glass substrate to form a single touch panel semi-finished product, because the double-sided tape is covered on the conductive glass substrate, the slivers will stick to each other after cutting, so force must be peeled off to form a single semi-finished product, which will easily cause glass The edge is not smooth; 2. The quality is poor. After cutting, the semi-finished product is cut to the edge of the glass to expose the glue thread, resulting in the edge of the semi-finished product.

The disadvantages are as follows: 1. The efficiency is low. Under the design of the adhesive pattern unit of most intervals, the double-sided adhesive-faced release paper must be torn off one by one before lamination, so that it is bound to be time-consuming and labor-intensive for large-scale lamination. procedures, resulting in reduced productivity

2. The quality is unstable. The operator tears off the double-sided tape and the release paper. Due to the influence of the operator's experience and insufficient training, the double-sided edge is often injured or damaged, which reduces the integrity of the double-sided adhesive tape.

Furthermore, in the follow-up process of semi-finished products, the surface of the conductive film is not protected by a soft transparent film, often due to insufficient training or negligence of the workers, the surface is scratched and dirty, which not only increases the defective rate but also increases the number of inspectors. The work and man-hours of wiping the surface are required. Therefore, it is necessary to add a workstation to attach a soft transparent film to the semi-finished product before proceeding to the next process. Although it can achieve the effect of protecting the surface, it also increases manpower and work hours virtually.
