Description

Technical Field

[0001] The utility model relates to the technical field of lamination of vehicle-mounted display screens, in particular to a lamination device for producing vehicle-mounted display screens. Background Art

[0002] There are two types of car display screens. One is a TV placed on the bus for viewing, which is essentially a car TV. The other is a small-sized car display, which generally has two video inputs, one for connecting to a car DVD and the other for connecting to a reversing image car camera. Some also have MP3 video playback and Bluetooth functions, and can be used on sports tools similar to cars, making them convenient for use in car sports.

[0003] After the production of the car display is completed, a layer of protective film needs to be pasted on the screen to increase the appearance when it is sold and prevent the screen from being damaged during subsequent movement and installation. The traditional method is to remove the artificial protective film from the protective film roll one by one, and then paste it one by one on the screen. During pasting, it is necessary to ensure that the protective film does not shift. After pasting, the bubbles in the protective film need to be squeezed out. The pasting efficiency is low, and dust is easily put on the screen during the pasting process, which needs to be improved. Utility Model Content
