Problems solved by technology

[0005] For example, the application publication number is: CN102716836A Chinese invention patent discloses a dispensing and laminating device and a method for dispensing and laminating a touch screen. The method for dispensing and laminating a touch screen is: initial preparation, placing the The plate and the functional sheet are placed on the stage, and the cover plate is adsorbed by the first translation structure of the dispensing and laminating device, and the functional sheet is alternately dispensed, and the cover plate and the functional sheet are After the cover plate and the functional sheet are bonded, the dispensing and laminating device is reset. This invention patent intends to protect the use of the dispensing and laminating device to carry out the dispensing and laminating of the touch screen and the cover plate. Although this The dispensing and laminating device can reduce operations and improve the efficiency of dispensing and laminating, but the precision and strength of the products after dispensing and laminating are often relatively ordinary.
[0006] Another example is that the application publication number is: CN102133568A, a kind of dispensing method and dispensing pattern for touch panels, by setting a pattern similar to a hollow X on the touch screen, so that the glue is drawn by the touch screen during the dispensing process. The central area of ​​the glue diffuses to the surroundings, so that the diffusion speed can be improved to a certain extent, and then the generation of air bubbles can be prevented. However, this dispensing method is only suitable for the bonding of planes and planes, not for planes and curved surfaces or curved surfaces. Bonding of curved surfaces
[0007] Another example is that the application publication number is: CN102234485A Chinese invention patent discloses a bonding method for workpieces of different materials. The thickness of the first adhesive glue and the second adhesive glue used on the surface, the selected first adhesive glue is pre-pressed on the bonding surface of the second workpiece, the first workpiece and the second workpiece are hot-pressed, cooled and shaped Although the first adhesive and the second adhesive after hot pressing can be compensated by the deformation tolerance, the process is cumbersome. At the same time, for the bonding of curved surface workpieces, the measurement is cumbersome and has errors, which may easily cause insufficient bonding strength.

Description

technical field [0001] The invention relates to an electronic product bonding method, in particular to the bonding of a touch screen and a front shell of a smart phone or a tablet phone. Background technique [0002] With the popularity of iphone4S and ipad all over the world, the development of smart phones and tablet computers is getting faster and faster. MID products with ultra-thin, touch screen and intelligent systems have become the latest consumer favorites. In the design and production process of notebooks, tablet computers and mobile phones, touch The screen part needs to be connected with the front shell, especially for components with high strength and precision requirements. Not every company can achieve high standards. [0003] Also in order to achieve the characteristics of no gap, high strength and flatness, more and more smartphones and tablets are assembled and bonded with adhesives. [0004] Nowadays, the screens and front shells of electronic products ar...
