Description

Technical Field

[0001] The utility model relates to the technical field of touch screen adhesive bonding, and more specifically to a touch screen adhesive backing clamp structure. Background Art

[0002] In the manufacturing process of touch screens, the attachment of adhesive (usually called double-sided adhesive) is a crucial link, especially in the attachment process of the viewing area frame (i.e. the touch area where users directly interact) and the housing frame (i.e. the border area where the periphery of the touch screen contacts the device housing). Double-sided adhesive not only needs to ensure the display clarity and touch sensitivity of the touch screen, but also needs to ensure the close fit and dustproof and waterproof performance between the touch screen and the device housing. The traditional touch screen double-sided adhesive attachment process is usually carried out separately. First, the viewing area frame sticker LCD double-sided adhesive is attached to the display area of ​​the touch screen separately. This step requires high-precision positioning and alignment to ensure that the display clarity and touch experience are not affected. Then, the housing frame sticker double-sided adhesive is attached to the outer frame of the touch screen. This step also requires precise alignment and attachment to ensure a stable connection and sealing between the touch screen and the device housing.

[0003] However, this separate attachment method has many shortcomings. First, separate attachment increases the complexity of the assembly process and requires more operation steps and manual participation, which not only reduces production efficiency but also increases production costs. Second, separate attachment may cause position deviation between the two double-sided adhesives, affecting the overall performance and appearance quality of the touch screen. In addition, separate attachment may also increase the risk of pollutants such as dust and impurities entering the interior of the touch screen, reducing the reliability and durability of the product. Therefore, we have made improvements to this and proposed a touch screen adhesive clamp structure. Utility Model Content
