Problems solved by technology

[0004] The vacuum degree of vacuuming in the above-mentioned traditional process cannot well solve the problem of air bubbles between the cover glass and the touch screen glass, and this problem directly leads to the need for subsequent roller rolling process to make up for it, which increases additional production time and cost

Embodiment Construction

[0013] In the traditional process of manufacturing touch screen modules, the vacuum degree is improved during vacuuming, which saves the process of rolling the roller, and improves the productivity while maintaining a high product yield.

[0014] Such as figure 1 As shown, it is a flow chart of making a touch screen module in this embodiment. include:

[0015] Step S10: Adsorbing the cover glass. The cover glass is the external protective part of the touch screen, which requires certain strength, scratch resistance and light transmittance. The glass cover plate in this process is pre-cut to meet the required size specifications. Clean the surface, especially the side that is attached to the glass of the touch screen, free of debris. The glass cover is picked up by the suction device and kept horizontally placed, and then sent to the predetermined fitting position.

[0016] Step S20: Place the touch screen glass. The touch screen glass is a sensing part that senses extern...

Abstract

The invention relates to a manufacturing method of a touch screen module, which belongs to the field of touch screen manufacturing. The manufacturing method of the touch screen module comprises the following steps: adsorbing a glass cover plate; placing touch screen glass; vacuumizing; pressing the glass cover plate to be bonded with the touch screen glass and defoaming, wherein in the steps of vacuumizing, a vacuum degree is controlled to from -100kPa to -90kPa. The vacuum degree is increased to further reduce a bubble appearing possibility in a bonding process, consequently, a roller wheel rolling procedure in the traditional procedures is omitted, and the production efficiency and the product yield are increased.

Description

【Technical field】 [0001] The invention relates to a method for manufacturing a touch screen, in particular to a method for manufacturing a touch screen module. 【Background technique】 [0002] In the production process of the touch screen module, the cover glass (CG for short) and the touch screen glass (ITO sensor for short ITO) are usually bonded by using optically clear adhesive (OCA for short), and the back cover glass is bonded together. The number of air bubbles between the glass and the touch screen is an important reference factor that affects the yield of finished products. [0003] The manufacturing process of the traditional touch screen module includes a series of processes such as absorbing the cover glass, placing the touch screen glass, vacuuming, pressing the cover glass to fit the touch screen glass, roller rolling, and defoaming. [0004] The vacuum degree of vacuuming in the above-mentioned traditional process cannot well solve the problem of air bubbles b...
