Description

Technical Field

[0001] This invention relates to the field of automotive sun visor lens film application technology, specifically an automatic automotive sun visor lens film application system. Background Technology

[0002] Car sun visor lenses typically refer to reflectors or interior rearview mirrors mounted on the sun visor. They are mainly used to reflect sunlight, provide rear visibility, and assist driving safety. The main function of applying shatterproof film to the lens is to prevent shards from flying and injuring people if the lens breaks, while also reducing damage to the lens from high-temperature environments. Therefore, during the production of car sun visor lenses, shatterproof film is applied to the lenses using film-applying equipment to improve safety.

[0003] Currently, when applying film to car sun visors, dust on the film surface causes uneven film application due to air bubbles. The dust collectors used are insufficient to clean the lens surface to the required cleanliness level, such as removing fingerprints. Furthermore, the film application equipment uses multiple independently driven winding and traction mechanisms, which are inconvenient to coordinate and control, costly, and prone to application deviations. The single-sided film application on car sun visors limits functionality. For films of varying thicknesses, adjusting the height of multiple components such as the film rollers and guide rollers is inconvenient. Summary of the Invention

[0030] Furthermore, there are two folding plates 8. The bottom of the folding plate 8 near the cross-cutting blade 10 is inclined. When the car sun visor lens needs to be edge-applied with film, the anti-shatter film required for the edge wrapping is reserved on both sides of the car sun visor lens during cross-cutting. The car sun visor lens is conveyed through the folding plate 8. The inclination of the bottom of the folding plate 8 will fold and press the anti-shatter film on both sides of the conveyed car sun visor lens to the side. The folding plate 8 gradually folds and presses the film to wrap the lens.

[0031] Furthermore, a counter 25 is installed on the protective box 2 on one side of the opening 6 below the No. 3 winding roller 53 via a mounting slot. This counter is an electromagnetic counting component. The counter 25 is electrically connected to the controller, and the counter 25 displays the winding length data on the display screen on the controller. The controller is electrically connected to the No. 1 motor 32, the No. 2 motor 54, and the No. 3 motor 585. When the counted length reaches the set value, the No. 1 motor 32 and the No. 2 motor 54 stop running, and the No. 3 motor 585 starts. The No. 3 motor 585 is programmed to operate in both forward and reverse directions.

[0032] The usage method of this embodiment is as follows: First, according to the model of the mass-produced car sun visor lens, the height and width of the film application spacing are adjusted. The servo motor 46 on the base 1 drives the first bevel gear set 45, the first connecting rod 47, and the first threaded rod 43 to rotate. The threaded sleeve 44 on the first threaded rod 43 moves up and down in the limiting groove 42. The height of the conveyor frame 3 and the conveyor belt 31 above the base 1 is adjusted by the support frame 41, realizing the integrated adjustment of the spacing between the film application dust roller 21, the third guide roller 22, the film application roller 16, the cross-cutting knife 10, and the third guide roller 22 and the conveyor belt 31. The height of the folding plate 8 and the limiting plate 24 are adjusted with the conveyor frame 3, which is convenient for adjustment. The dual-axis motor 76 on the adjusting seat 72 drives the bidirectional screw 74 in the adjusting groove 73 to rotate. The bidirectional screw 74 drives two screw sleeves 75 to move away from or towards each other on the adjusting seat 72. The first adjusting mechanism 7 adjusts the distance between the two folding plates 8, allowing the two folding plates 8 to fold and apply the shatterproof film to the car sun visor lens. When folding and applying the film to the car sun visor lens is not required, the first adjusting mechanism 7 moves the two folding plates 8 away from each other to both sides of the protective box 2, away from the car sun visor lens. Similarly, the second adjusting mechanism 9 adjusts the distance between the two cross-cutting blades 10, allowing the two cross-cutting blades 10 to make cross-cuts on both sides of the car sun visor lens. Similarly, the third adjusting mechanism 23 adjusts the distance between the two limiting plates 24, allowing the two limiting plates 24 to move on the conveyor belt 31. The car sun visor lens is conveyed and positioned. The anti-shatter film for applying the car sun visor lens on the first delivery roller 11 enters the protective box 2 through the opening 6. The anti-shatter film passes sequentially through the limiting roller 12, the first guide roller 13, the lower guide roller 14 and the upper guide roller 15, the film application roller 16, and the second guide roller 17. The protective film (release paper) on the surface of the anti-shatter film is torn open at the lower guide roller 14. The protective film is led out of the protective box 2 through the opening 6 via the upper guide roller 15 and wound onto the second take-up roller 52. The dust-adhesive film on the second delivery roller 20 enters the protective box 2 through the opening 6. After being conveyed by the dust-adhesive roller 21 and the third guide roller 22, the dust-adhesive film is led out of the protective box 2 through the opening 6 and wound onto the third take-up roller 53. The second motor 54 drives the second bevel gear set 55 on the first take-up roller 51 to rotate, and through the second connecting... The connecting rod 56 drives the second bevel gear set 55 on the second and third take-up rollers 52 and 53 to rotate. The rotation of the second bevel gear set 55 drives the first roller shaft seat 59 on the bracket 57 to rotate. This causes the first take-up roller 51, the second take-up roller 52, and the third take-up roller 53 between the first and second roller shaft seats 59 and 510 to rotate synchronously and at the same speed on the bracket 57 and roller shaft frame 58. The edge material of the anti-shatter film is wound onto the first take-up roller 51, the protective film torn off the anti-shatter film is wound onto the second take-up roller 52, and the dust-adhesive film is wound onto the third take-up roller 53. The dust-adhesive film, the protective film of the anti-shatter film, and the edge material of the anti-shatter film are synchronously and at the same speed, so that the dust-adhesive film, the film, and the edge material are recycled in a coordinated and consistent manner at the same speed. During the winding process...The material passing through the through-hole 6 is 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, driving the No. 3 bevel gear set 584 and the connecting rod to rotate, which in turn drives the No. 2 threaded rod 582 on the guide rail seat 581 to rotate. The threaded slide 583 on the No. 2 threaded rod 582 drives the roller frame 58 to move on the guide rail seat 581. The roller frame 58 moves away from the protective box 2, and the No. 2 roller seat 510 on the roller frame 58 separates from the spline shaft 511. 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 seat 59 on the bracket 57. Then, the new No. 1 winding roller 51 and the No. 2 winding roller 52 are removed. The splined shaft 511 of the No. 3 take-up roller 53 is inserted into the splined groove of the No. 1 roller shaft seat 59. 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 shaft frame 58 to move closer to the splined shaft 511. The splined shaft 511 is inserted into the splined groove of the No. 2 roller shaft seat 510 on the roller shaft frame 58. That is, the No. 1 take-up roller 51, the No. 2 take-up roller 52, and the No. 3 take-up roller 53 are clamped and installed on the No. 1 roller shaft seat 59 and the No. 2 roller shaft seat 510. The No. 1 take-up roller 51, the No. 2 take-up roller 52, and the No. 3 take-up roller 53 synchronously count the winding length. The winding, disassembly, and replacement are convenient. The No. 1 motor 32 on the conveyor frame 3 drives the conveyor roller and the conveyor belt 3. 1. Continuous operation: The car sun visor lens is conveyed onto the conveyor belt 31 by the limiting plate 24 and enters the protective box 2. The car sun visor lens passes through the dust-adhesive roller 21 and the third guide roller 22. The dust-adhesive film removes dust from the film-applying surface of the car sun visor lens, achieving automatic dust removal for film application. The film-applying surface is clean, and the film is tightly applied without air bubbles. After dust removal, the car sun visor lens is conveyed to the film-applying roller 16, which applies the shatterproof film to the car sun visor lens. The car sun visor lens passes through the cross-cutting blade 10 to remove excess shatterproof film from both sides. When the car sun visor lens requires side film application, the cross-cutting process leaves a shatterproof film margin on both sides of the car sun visor lens for edge wrapping. The lens is conveyed through the folding and pressing plate 8, which folds and presses the shatterproof film on both sides of the car sun visor lens, realizing automatic film application and edging pressing of the car sun visor lens. The electric telescopic rod drives the longitudinal cutter 19 to move downward, and the linear module 18 drives the longitudinal cutter 19 to move, longitudinally cutting the shatterproof film at both ends of the car sun visor lens. The edge material cut off by the film application is wound on the first take-up roller 51, realizing automatic film application of the car sun visor lens. The automatic film application feeding operation is highly efficient. The limiting roller 12 and the limiting plate 24 limit the film feeding and prevent deviation, ensuring precise film application. The automatic film application control is simple, energy-saving and environmentally friendly. The film application height and width are adjustable, suitable for applying films to car sun visor lenses of different thicknesses and widths.
