Description

Technical Field

[0002] With the continuous development of electronic technology, the use of televisions and computers is becoming more and more widespread, and the display screen, as its input and output component, is an indispensable key link. In the production process of the display screen, one of the important production steps is to paste the display module and the touch module into a complete touch-controlled display screen, or to paste and mold the backlight panel and the display module into a complete display screen, or to paste the display module and the 3D module into a 3D display screen, all of which need to be completed by a bonding process. The traditional bonding process is generally implemented by manual operation, but this manual operation method has the disadvantages of high bonding cost, low bonding efficiency, low product qualification rate, large product quality error, and unstable product quality. 3D imaging is produced by the visual difference between the two eyes of the human body. Traditional 3D display screens often require viewers to wear glasses to watch, which is inconvenient to operate and use. There is an urgent need for a 3D display screen that can be watched without wearing glasses. Some existing bonding processes also use semi-automatic methods for production, which require manual cooperation with semi-automatic equipment to complete the bonding of screen components one by one, and the continuous operation effect is poor and the bonding efficiency is low.

[0037] Embodiment 2. The difference between this embodiment and embodiment 1 is that the rotating device in embodiment 1 actually has only four workstations, and simply bonds two screens together. However, sometimes we need to bond multiple screens, such as display screens, backlight panels, and touch screens together, and we need to add workstations. By adding workstations on the basis of embodiment 1, vacuum bonding of multiple screens can be achieved.
