The key is extended and retracted by controlling the knob. When the first film needs to be replaced, the knob is first rotated to retract the key, the film roll is removed, and the new film roll is put in and the knob is rotated. The key extends and presses against the inner wall of the first film roll to fix the film roll. The mechanical expansion shaft is a conventional product in the field and is not described in detail here.

[0026] Preferably, the first film collecting station 2 comprises a disassembly plug 21, a film collecting shaft 22, a fixed plug 23, a coupling 26, a damper 27, and a driving motor 28; The driving motor 28 is electrically connected to the damper 27.

The other end of the coupling 26 is connected to the film collecting shaft 22 through the film collecting shaft support 25. The fixed plug 23 and the disassembly plug 21 are both sleeved on the film collecting shaft and coaxially fixed with the film collecting shaft 22, and the fixed plug 23 is arranged on one side where the film collecting shaft 22 is connected to the coupling 26; the disassembly plug 21 is arranged on the other side of the film collecting shaft 22; After the first film has finished coating the glass cover plate, it is wound onto the film collecting shaft 22 , and the first film is wound between the fixed plug 23 and the disassembly plug 21 .

[0027] Specifically, the disassembly plug 21 of this embodiment is fixed on the film collection shaft 22 by threads, and cooperates with the fixed plug to clamp the first film wound on the film collection station, wherein the disassembly plug can be disassembled by a rotating nut arranged on a side away from the fixed plug 23.

[0031] Specifically, the conveying station 7 of this embodiment includes a tensioning device 71 , a belt 72 , a chain 73 , a transmission group 74 , and a second driving motor 75 .

[0032] Specifically, the second film of this embodiment is transmitted synchronously with the belt through the rotating shaft driven by the belt through the action of friction. After the upstream equipment places the glass cover plate on the second film, the belt moves synchronously with the second film and enters the laminating station to clean the dust through the joint action of the first film and the second film.

[0033] Specifically, in the mechanism for cleaning dust on the surface of the glass cover plate of this embodiment, the power source of the whole set of equipment is the second drive motor 75, which drives the conveying station 7 and the laminating station 6 at the same time through the transmission group 74, thereby ensuring the consistency of the overall movement speed. The transmission group includes a synchronous belt, a synchronous pulley, and an idler pulley for conveniently adjusting the tightness of the synchronous belt.

[0034] Specifically, in the coating mechanism 6 of the present embodiment, only the lower adhesive roller is driven by the second driving motor 75, and the upper adhesive roller is driven to rotate by the friction force generated by the lower adhesive roller and the glass cover plate, and by the friction force of the top of the glass cover plate. The spacing between the upper and lower rollers is adjusted by the expansion box to meet the production of glass cover plates of various thicknesses, while controlling the adhesion force between the film and the glass cover plate.

[0035] The driving motor 28 in the first film collecting station 2 and the second film collecting station 4 is used to collect the used first film and the second film, and remove the excess force through the action of the damper, so as not to generate additional pulling force on the front end coating mechanism 6, thereby avoiding that as the diameter of the film roll in the film collecting station increases, the linear speed gradually increases, which affects the uniform movement of the front end.

[0036] The specific working principle of this embodiment is as follows: As shown in the figure, first install the first film roll and the second film roll on the first film placing station and the second film placing station respectively. The head end of the first film enters the laminating station through the guiding station, and is wound on the first film receiving station after coming out of the laminating station. The second film enters the laminating station through the conveying station, and is wound on the second film receiving station after coming out of the laminating station. Then start the equipment, the first roll and the second film roll will move at a uniform speed, at this time, the upstream equipment puts the glass cover plate on the film roll of the second laminating station in turn, the glass cover plate moves synchronously with the second film, and is coated on the upper and lower surfaces of the glass cover plate through the laminating station to clean the dust. The cleaned film is sorted and collected by the second film receiving station and the first film receiving station, and the glass cover plate continues to move to the downstream equipment.

[0037] The present invention is a device for cleaning the surface of a glass cover plate by sticking a mucous film to remove dust. It is mainly used in the glass cover plate manufacturing and installation industry of electronic products such as mobile phones to remove fine dust on the surface of the glass cover plate. The first film and the second film are used to clean the dust on both sides of the glass cover plate by sticking a mucous film, respectively. The cleaning effect is good, which greatly improves the yield of the downstream production line, while reducing the dependence on manual labor and avoiding secondary contamination of the glass cover plate by manual labor (fingerprints, etc.). It can reduce the industry's excessive dependence on manual labor and improve production line efficiency. It has been verified that the inspection rate of downstream equipment has increased from the original 40% to 60% using the cleaning mechanism of this embodiment.
