Description

Technical Field

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

[0002] Touch screens are widely used in various electronic products for data display or operation instructions. In order to protect the touch screen from being scratched by hard objects during packaging and transportation, a protective film is applied to the surface of the touch screen during production.

[0003] The coating of existing touch screens during production is generally done manually, which not only has low operating efficiency but also makes it difficult to ensure the coating quality.

[0004] For example, a coating device for touch screen production disclosed in Chinese patent CN216734942U is provided. The touch screen is placed on a conveyor for linear transmission through the arrangement of a hydraulic cylinder, a support plate, a coating assembly, a screw rod, a limit rod, a slider, a cutter and a first motor. The touch screen is placed on a conveyor for linear transmission. The support plate is driven down by the hydraulic cylinder to adjust the coating roller to be flush with the surface of the touch screen. One end of the protective film passes between the touch screen and the coating roller. The spring acts on the connecting frame to make the coating roller press the protective film onto the surface of the touch screen. The second motor is started to drive the film wrapping roller to rotate and release the protective film. When the touch screen is transported with the conveyor, the coating is completed. The conveyor and the second motor are started and stopped intermittently, and then the first motor is started. The first motor drives the screw rod to rotate, thereby driving the slider to move, driving the cutter to move, and cutting the protective film.

[0005] However, when the device is in use, the film is attached to the touch screen, and since the touch screen may shift when the film is applied, deviation of the applied film may occur.

[0006] For this reason, we urgently need to provide a film coating device for touch screen production. Utility Model Content

[0007] The utility model aims to provide a coating device for touch screen production, so as to solve the problem that the film is attached to the touch screen during use, and the touch screen will be offset during coating, thus causing coating deviation.
