Description

[0002] Car sun visor lenses usually refer to reflectors or interior rearview mirrors installed on the sun visor. They are mainly used to reflect sunlight, provide rear vision, and assist driving safety. The main function of sticking anti-shatter film on the lens is to prevent the fragments from flying and injuring people after the lens is broken, while reducing the damage to the lens in high temperature environments. Therefore, during the production of car sun visor lenses, anti-shatter film is stuck on the car sun visor lenses through film-sticking equipment to improve safety.

[0003] At present, when applying film to car sun visor lenses, dust on the film-applying surface of the lens causes uneven film bubbles, and the dust collector used is difficult to clean the lens surface to the cleanliness required for film application, such as fingerprints on the lens surface; the film-applying equipment uses multiple independently driven reels and tractions, and the coordinated control between the multiple reels and tractions is inconvenient and costly, and film-applying deviations are prone to occur. The car sun visor lens is only applied on one side with a single function. When applying film to lenses of different thicknesses, it is inconvenient to adjust the height of multiple components such as the film-applying rollers and guide rollers of the film-applying equipment.

The bidirectional screw 74 drives the two screw sleeves 75 to move away from or closer to each other on the adjustment seat 72. The No. 1 adjustment mechanism 7 adjusts the distance between the two folding plates 8 so that the two folding plates 8 can fold and apply the anti-shatter film pasted on the car sun visor lens. When the car sun visor lens does not need to be folded and applied, the two folding plates 8 are moved away from each other to the two sides of the protective box 2 through the No. 1 adjustment mechanism 7, and the folding plates 8 are away from the car sun visor lens. Similarly, the distance between the two cross-cutters 10 is adjusted by the No. 2 adjustment mechanism 9, so that the two cross-cutters 10 cross-cut the film on both sides of the car sun visor lens. Similarly, the distance between the two limit plates 24 is adjusted by the No. 3 adjustment mechanism 23, so that the two limit plates 24 are on the conveyor belt 31. The car sun visor lens is limited and transported, the anti-shatter film for the car sun visor lens on the No. 1 delivery roller 11 enters the protection box 2 from the through port 6, the anti-shatter film passes through the limiting roller 12, the No. 1 guide roller 13, the lower guide roller 14 and the upper guide roller 15, the film roller 16 and the No. 2 guide roller 17 in sequence, the protective film (release paper) on the adhesive surface of the anti-shatter film is torn at the lower guide roller 14, the protective film is led out of the protection box 2 from the through port 6 through the upper guide roller 15 and wound on the No. 2 winding roller 52, the sticky film on the No. 2 delivery roller 20 enters the protection box 2 from the through port 6, the sticky film is transported by the sticky roller 21 and the No. 3 guide roller 22 and led out of the protection box 2 from the through port 6 and wound on the No. 3 winding roller 53, the No. 2 motor 54 drives the No. 2 bevel gear set 55 on the No. 1 winding roller 51 to rotate, and the No. 2 connecting roller 54 is connected to the No. 2 connecting roller 54. The connecting rod 56 drives the second bevel gear set 55 on the second winding roller 52 and the third winding roller 53 to rotate. The rotation of the second bevel gear set 55 drives the first roller seat 59 on the bracket 57 to rotate, driving the first winding roller 51, the second winding roller 52 and the third winding roller 53 between the first roller seat 59 and the second roller seat 510 to keep synchronously winding and rotating at the same speed on the bracket 57 and the roller frame 58. The edge material of the anti-shatter film is wound on the first winding roller 51, the protective film torn off the anti-shatter film is wound on the second winding roller 52, and the dust-sticking film after dust is stuck is wound on the third winding roller 53. The dust-sticking film, the protective film of the anti-shatter film and the edge material of the anti-shatter film are synchronously pulled and wound at the same speed, so that the dust sticking, film sticking and edge material recovery run in coordination and at the same speed. During the winding process,The materials passing through the passage 6 are counted by the counter 25. When the winding needs to be disassembled, the No. 3 motor 585 on the guide rail seat 581 rotates forward to drive the No. 3 bevel gear set 584 and the connecting rod to rotate, driving the No. 2 threaded rod 582 on the guide rail seat 581 to rotate, and the threaded slide 583 on the No. 2 threaded rod 582 drives the roller shaft frame 58 to move on the guide rail seat 581. The roller shaft frame 58 is away from the protective box 2, and the No. 2 roller shaft seat 510 on the roller shaft frame 58 is separated from the spline shaft 511, and the No. 1 winding roller 51, the No. 2 winding roller 52 and the No. 3 winding roller 53 are removed from the No. 1 roller shaft seat 59 on the bracket 57, and then the new No. 1 winding roller 51, the No. 2 winding roller 52 and the No. 3 winding roller 53 are removed from the No. 1 roller shaft seat 59 on the bracket 57, and then the new No. 1 winding roller 51, the No. 2 winding roller 52 The spline shaft 511 of the No. 3 winding roller 53 is inserted into the spline groove of the No. 1 roller seat 59, and the No. 3 motor 585 reverses to drive the No. 3 bevel gear set 584 and the No. 2 threaded rod 582, pushing the roller frame 58 to move close to the spline shaft 511. The spline shaft 511 is inserted into the spline groove of the No. 2 roller seat 510 on the roller frame 58, that is, the No. 1 winding roller 51, the No. 2 winding roller 52 and the No. 3 winding roller 53 are clamped and installed on the No. 1 roller seat 59 and the No. 2 roller seat 510. The No. 1 winding roller 51, the No. 2 winding roller 52 and the No. 3 winding roller 53 are synchronously wound and counted, and the winding, disassembly and replacement are convenient. The No. 1 motor 32 on the conveyor frame 3 drives the conveyor roller to drive the conveyor belt 3 1 is in continuous operation. The car sun visor lens is conveyed into the protective box 2 on the conveyor belt 31 through the limiting plate 24. The car sun visor lens passes through the sticky dust roller 21 and the third guide roller 22. The sticky dust film removes the dust on the film surface of the car sun visor lens, realizing the dust-adhesive treatment of the car sun visor lens automatic film application. The film application surface is clean, the film application is tight and there are no bubbles. After the car sun visor lens is dusted, it is conveyed to the film application roller 16. The film application roller 16 sticks the anti-shatter film on the car sun visor lens. The car sun visor lens passes through the cross-cutting knife 10 to cut off the excess anti-shatter film on both sides. When the car sun visor lens needs to be filmed on the side, the anti-shatter film required for the edging is reserved on both sides of the car sun visor lens during cross-cutting. The lenses are conveyed through the folding plate 8, which folds and presses the anti-shatter film on both sides of the car sun visor lens, achieving automatic film application, edge wrapping and laminating. The electric telescopic rod drives the slitting knife 19 downward, and the linear module 18 drives the slitting knife 19 to move, slitting the anti-shatter film on both ends of the car sun visor lens. The cut edge of the film is reeled up on the first reeling roller 51, achieving automatic film application for the car sun visor lens. The automatic film feeding operation is efficient. The limit roller 12 and limit plate 24 limit the film feeding to prevent deviation, ensuring precise film application and simple automatic film application control. It is energy-saving and environmentally friendly. The film application height and width are adjustable, suitable for film application of car sun visor lenses of different thicknesses and widths.
