Description

Technical Field

[0002] With the development of science and technology, touch-type LCD screens are now used in many devices, such as mobile phones, computers, and human-computer interaction screens for CNC machine tools. They are widely used and have a trend of further development. When producing and processing such touch-type LCD screens, one of the important steps is to attach the touch screen to the LCD screen to achieve the purpose of making the LCD screen have a touch function.

[0003] The existing disclosed technology has a publication number of CN219143437U, which discloses a pressing device for a touch screen, including a fixing frame, a fixing frame, a push plate, a shell and a driving member, wherein the fixing frame is fixedly connected to a cylinder, the piston rod of the cylinder is provided with a plurality of pressure plates, and the plurality of pressure plates are spliced ​​with each other, the fixing frame is fixedly connected to the bottom end of the fixing frame, the push plate is slidably mounted on one end of the fixing frame, the shell is fixedly arranged on the base, and an inclined block is slidably arranged in the shell. In the utility model, after the touch screen is placed in the fixing frame, the slow movement of the inclined block can be achieved by the rotation of the threaded rod of the servo motor, and then the inclined block is resisted by the push rod and the push rod is compressed by the first spring, so the touch screen can be firmly clamped on the fixing frame by the push plate and the clamping plate, and the servo motor can be turned off after completion.

[0004] Although the above patent can firmly clamp the touch screen on the fixed frame through the push plate and the clamping plate, there are still some shortcomings in its use. First, the patent does not press the touch screen in a vacuum environment. During the pressing process, bubbles are easily generated between the touch screen and the display screen, which increases the scrap rate of the touch screen production. Secondly, the patent can only clamp and fix the two sides of the touch screen, but cannot clamp the touch screen all around. The stability of the touch screen clamping is not strong enough. For the problems in the relevant technology, no effective solution has been proposed yet. Utility Model Content
