Description

Technical Field

[0001] The utility model relates to the technical field of pressing devices, in particular to a pressing device for processing a touch display screen. Background Art

[0002] From a screen's structural perspective, we can roughly divide the screen into three parts: the protective glass, the touchscreen, and the display. These three parts need to be bonded together during the LCD production process. Currently, LCDs primarily utilize full bonding technology, which involves seamlessly bonding the panel and touchscreen together using either water-based or optical adhesive. Generally, two bonding steps are required: one between the protective glass and the touchscreen, and another between the display and the touchscreen.

[0003] During the production process of liquid crystal displays, after two screens are bonded together with glue, they need to be pressed together using a pressing device. Since the pressing distance of the pressing plate is fixed each time, only liquid crystal displays of a single thickness can be produced. When the thickness of the liquid crystal display changes, pressing down according to the original pressing distance will cause excessive pressure on the liquid crystal display, causing the liquid crystal display to be crushed, thereby requiring a new pressing device to be replaced, resulting in increased costs. Therefore, a pressing device for processing touch screen displays is proposed. Utility Model Content
