Abstract

The present invention discloses a film laminating device and a film laminating method for swimming goggles, and relates to the field of film laminating equipment. In the present invention, a coil with a protective film is pulled and conveyed by a reeling and unreeling mechanism. When the coil passes the end position of a bending part, the coil is bent under the abutment and limiting action of the end of the bending part. At this time, the protective film on the coil remains flat under the action of its own rigidity, so that the protective film is gradually separated from the coil, and the separated protective film gradually extends to the bottom of the pressure roller as the coil moves. The pressure roller then presses the protective film onto the lens on the top surface of the positioning fixture; the lens is laminating with the pre-cut protective film, so that the protective film does not need to be cut on the lens during laminating, thereby preventing the lens from being scratched due to the cutting of the protective film, which is beneficial to improving the yield rate of the lens. The protective film can be automatically separated from the coil by the cooperation of the reeling and unreeling mechanism and the bending part, thereby realizing automatic laminating.

[0004] In response to the problems in the related art, the present invention proposes a film pasting device and a film pasting method for swimming goggles processing to overcome the above technical problems existing in the existing related art.

[0005] To solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The present invention provides a film laminating device, comprising a frame, on which are sequentially provided a winding and unwinding mechanism, a film laminating mechanism, and a jig assembly. The winding and unwinding mechanism can synchronously wind and unwind a roll of material with a protective film, so as to pull and convey the roll of material by winding and unwinding.

The top surface of the positioning jig is provided with a positioning groove capable of engaging and positioning a workpiece with the film laminating.

The transverse adjustment screw is threadedly connected to the transverse adjustment slide, and a transverse adjustment knob is fixedly mounted on one end of the transverse adjustment screw. A support seat is fixedly mounted on the top of the transverse adjustment slide, and the positioning jig is fixedly mounted on the top of the support seat.

[0012] Furthermore, the bending member includes a guide plate, which is arranged to be tilted and fixedly mounted on the frame, and one end of the guide plate is provided with a guide bending portion, and the guide bending portion is an acute-angle structure.

[0013] Furthermore, the lifting drive assembly includes a lifting cylinder, which is fixedly installed on the upper end of the frame. A lifting frame is fixedly installed on the telescopic end of the bottom of the lifting cylinder. Elastic telescopic rods are installed at both ends of the lifting frame. A support rod is fixedly installed between the two elastic telescopic rods, and the pressure roller is rotatably installed on the surface of the support rod.

[0014] Furthermore, the elastic telescopic rod includes a suspension rod, which is slidably inserted into the end of the lifting frame, the top end of the suspension rod extends above the lifting frame and is fixedly installed with a top plate, the bottom end of the suspension rod is fixedly connected to the end of the support rod, and the lower end of the suspension rod is movably sleeved with a pressure spring located between the lifting frame and the support rod.

[0015] Furthermore, the film-sticking mechanism also includes an adsorption and positioning component located above the bending part, and the adsorption and positioning component includes a movable lifting unit and a vacuum suction cup. The vacuum suction cup can adsorb and reinforce the protective film when the protective film is separated from the roll material to increase the rigidity of the protective film. The movable lifting unit can drive the vacuum suction cup to move synchronously with the protective film and the roll material.

[0016] Furthermore, the mobile lifting unit includes a guide groove and a telescopic cylinder, the guide groove is opened at the upper end of the frame and is arranged parallel to the bending piece, a limit seat is slidably installed inside the guide groove, the telescopic cylinder is fixedly installed at the upper end of the frame, and the telescopic end of the telescopic cylinder is fixedly connected to the outer end of the limit seat, and the inner end of the limit seat is fixedly installed with a bracket extending above the bending piece;

[0017] A suction cup driving cylinder is fixedly installed on the top of the bracket, the telescopic end of the suction cup driving cylinder extends to the bottom of the bracket and is fixedly installed with a connecting frame, and the vacuum suction cup is fixedly installed on the front side end of the connecting frame.

[0018] The present invention also discloses a film-attaching method for swimming goggles, the specific steps of which are as follows:

[0019] First, the coil with the protective film is synchronously wound and unwound by the winding and unwinding mechanism, so that the coil is pulled and conveyed by winding and unwinding. When the coil passes the end position of the bending part, the coil is bent under the abutment and limiting action of the bending part end. At this time, the protective film on the coil remains straight due to its own rigidity, so that the protective film and the coil are gradually separated. The separated protective film gradually extends below the pressure roller as the coil moves.

[0020] Then, the winding and unwinding of the coil is stopped, so that the coil conveyance stops, and at the same time, the lens of the swimming goggle is placed in the positioning groove on the positioning fixture, and the positioning fixture is driven by the translation drive unit to move to the bottom of the protective film;

[0021] Then, the lifting drive assembly drives the pressing roller downward, so that the pressing roller presses the protective film down and adheres it to the goggle lens. Then, the reel is driven by the reeling and unreeling mechanism to continue to move and convey the material, so that the protective film continues to separate from the material and extend to the left. At the same time, the translation drive unit drives the positioning fixture and the goggle lens to move synchronously to the left, and the pressing roller gradually rolls the protective film onto the goggle lens.

[0022] Until the protective film is completely attached to the goggle lens, the pressure roller is driven upward and reset by the lifting drive assembly, and then the positioning fixture and the goggle lens are driven to move to the left and reset by the translation drive unit, and the goggle lens with the protective film attached to the positioning fixture is removed. This process is repeated back and forth, and the goggle lens can be continuously filmed.

[0023] The present invention has the following beneficial effects:

[0024] 1. In the present invention, a roll of material with a protective film is wound and unwound by a winding and unwinding mechanism to pull and transport the roll. When the roll passes the end position of the bending part, the roll is bent under the abutment and limiting action of the end of the bending part. At this time, the protective film on the roll remains straight due to its own rigidity, so that the protective film is gradually separated from the roll, and the separated protective film gradually extends to the bottom of the pressure roller as the roll moves. Then, the pressure roller presses the protective film onto the lens on the top surface of the positioning fixture; the lens is applied with the pre-cut protective film, so that the protective film does not need to be cut on the lens during application, which can effectively prevent the lens from being scratched due to the cutting of the protective film, which is beneficial to improving the yield rate of the lens, and the protective film is pre-applied and stored on the roll, which makes the storage and use of the protective film more convenient; and through the cooperation of the winding and unwinding mechanism and the bending part, the protective film can be automatically separated from the roll, thereby realizing an automatic film application process and improving the efficiency of lens application.

[0025] 2. The pressure roller in the present invention is connected to the lifting cylinder through an elastic telescopic rod. When the lifting cylinder drives the elastic telescopic rod and the pressure roller downward, the pressure roller can abut against the lens under the elastic force of the elastic telescopic rod, thereby preventing the lens from being damaged by excessive pressure of the pressure roller. Moreover, when applying the film, the elastic telescopic rod can automatically adjust the height of the pressure roller according to the curvature of the lens surface, so that the pressure roller is always pressed tightly against the lens surface, thereby improving the rolling and film applying effect of the pressure roller.

[0026] 3. In the present invention, a vacuum suction cup is installed above the bending part through a movable lifting unit. When the roll moves through the end of the bending part and the protective film is separated from the roll due to its own rigidity, the vacuum suction cup can be driven by the movable lifting unit to adsorb on the top surface of the protective film and move synchronously with the protective film, so that the protective film is adsorbed and reinforced by the vacuum suction cup to increase the rigidity of the protective film, ensuring that the protective film remains straight and separated from the roll when the roll is bent, thereby ensuring that the film laminating process is carried out stably.

[0027] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] Among them, multiple groups of protective films corresponding to the lenses of the swimming goggles are provided on the roll. When the lenses of the swimming goggles are filmed by the film-laminating device, the roll with the protective film is firstly wound and unwound synchronously by the rewinding and unwinding mechanism 2, so that the roll is pulled and conveyed by winding and unwinding. When the roll is conveyed through the end position of the bending part, the roll is bent under the abutment and limiting action of the end of the bending part. At this time, the protective film on the roll remains straight under the action of its own rigidity, so that the protective film is gradually separated from the roll, and the separated protective film gradually extends to the bottom of the pressure roller 38 as the roll moves; when the protective film is partially separated from the roll (about one-third of the area of ​​the protective film), the winding and unwinding of the roll is stopped, so that the roll stops being conveyed, and at the same time, the lenses of the swimming goggles are placed in the positioning grooves on the positioning jig 42, and driven by the translation drive unit The positioning jig 42 moves to the bottom of the protective film; then the lifting drive assembly drives the pressure roller 38 downward, so that the pressure roller 38 presses the protective film down and fits it on the goggle lens, and then the roll is driven by the reeling and unreeling mechanism 2 to continue to move and convey, so that the protective film continues to separate from the roll and extend to the left, and at the same time, the positioning jig 42 and the goggle lens are driven to move synchronously to the left by the translation drive unit, and then the pressure roller 38 gradually rolls the protective film to fit it on the goggle lens; until the protective film is completely fitted on the goggle lens, the film application of this round of lenses is completed, and then the lifting drive assembly drives the pressure roller 38 to reset upward, and then the translation drive unit drives the positioning jig 42 and the goggle lens to continue to move to the left and reset, and the goggle lens with the protective film on the positioning jig 42 is removed, and so on and so forth, repeating the above steps, and the goggle lenses can be continuously filmed.

[0045] In this embodiment, the lens is applied with a pre-cut protective film, so that there is no need to cut the protective film on the lens when applying the film, which can effectively prevent the lens from being scratched due to the cutting of the protective film, which is beneficial to improving the yield rate of the lens. The protective film is pre-attached and stored on the roll material, which can make the storage and use of the protective film more convenient; and through the cooperation of the reeling and winding mechanism 2 and the bending part, the protective film can be automatically separated from the roll material, thereby realizing the automatic film application process and improving the efficiency of lens film application.

[0046] Example 2

[0047] See also Figure 1-Figure 4 As shown, the difference between this embodiment and the above embodiment is that the unwinding and rewinding mechanism 2 includes an unwinding roller 21, a rewinding motor 23, a rewinding roller 24 and a plurality of guide rollers 22. The unwinding roller 21, the rewinding roller 24 and the plurality of guide rollers 22 are all rotatably mounted on the frame 1, and the rewinding motor 23 is fixedly mounted on the frame 1 and is transmission-connected to the rewinding roller 24.

[0048] Among them, the coil with a protective film is installed on the unwinding roller 21, and then the coil is tensioned and guided by the bending part and multiple guide rollers 22 and then wound on the winding roller 24. When the film is applied, the winding roller 24 is driven to rotate by the winding motor 23, so that the coil can be pulled and moved for transportation, and when the coil is transported through the bending part, it can bend under the abutment and limiting action of the bending part, so that the protective film on the coil is gradually separated from the coil.

[0049] Example 3

[0050] See also Figure 1 、 Figure 2 、 Figure 7 、 Figure 8 As shown, the difference between this embodiment and the above embodiment is that the translation drive unit includes a linear motor 41, which is fixedly mounted on the top surface of the frame 1, and a sliding base 43 is installed on the top surface of the linear motor 41, and an adjustment base is installed on the top surface of the sliding base 43, and a positioning fixture 42 is fixedly mounted on the top of the adjustment base;

[0051] When applying film to the lens of the swimming goggle, first place the lens in the positioning groove on the top surface of the positioning fixture 42, and then use the linear motor 41 to drive the sliding base 43 to move toward the pressure roller 38 and the protective film, so that the sliding base 43 drives the positioning fixture 42 and the lens to move under the pressure roller 38 and the protective film. When the pressure roller 38 presses down to apply the film, the linear motor 41 drives the sliding base 43, the positioning fixture 42 and the lens to move to the left synchronously with the protective film, so that the pressure roller 38 rolls the protective film to fit the surface of the lens.

[0052] Furthermore, the adjustment seat includes a longitudinal adjustment slide 44 and a longitudinal adjustment screw 45. The longitudinal adjustment slide 44 is slidably mounted on the top surface of the sliding base 43, and the longitudinal adjustment screw 45 is rotatably mounted above the sliding base 43. The longitudinal adjustment screw 45 is threadedly connected to the longitudinal adjustment slide 44, and one end of the longitudinal adjustment screw 45 is fixedly mounted with a longitudinal adjustment knob 46; a transverse adjustment slide 47 is slidably mounted on the top surface of the longitudinal adjustment slide 44, and a transverse adjustment screw 48 is rotatably mounted above the longitudinal adjustment slide 44, and the transverse adjustment screw 48 is threadedly connected to the transverse adjustment slide 47, and one end of the transverse adjustment screw 48 is fixedly mounted with a transverse adjustment knob 49, and the top of the transverse adjustment slide 47 is fixedly mounted with a support seat 410, and the positioning fixture 42 is fixedly mounted on the top of the support seat 410;

[0053] Among them, the longitudinal adjustment knob 46 can drive the longitudinal adjustment screw 45 to rotate, so that the longitudinal adjustment screw 45 drives the longitudinal adjustment slide 44 to adjust longitudinally on the sliding base 43 through thread transmission, thereby adjusting the longitudinal position of the positioning jig 42 and the lens, and the transverse adjustment knob 49 can drive the transverse adjustment screw 48 to rotate, so that the transverse adjustment screw 48 drives the transverse adjustment slide 47 to move transversely on the longitudinal adjustment slide 44 through thread transmission, thereby adjusting the transverse position of the positioning jig 42 and the lens, and by adjusting the longitudinal and transverse directions of the positioning jig 42 and the lens, when the linear motor 41 drives the positioning jig 42 and the lens to move to the bottom of the pressure roller 38, the lens can be accurately aligned with the protective film and the pressure roller 38, so as to improve the accuracy and effect of lens film pasting.

[0054] Example 4

[0055] See also Figures 1-6 As shown, the difference between this embodiment and the above embodiment is that the bending part includes a guide plate 31, the guide plate 31 is arranged to be fixedly installed on the frame 1 at an angle, and a guide bending portion is provided at one end of the guide plate 31, and the guide bending portion is an acute-angle structure; when the coil moves through the guide bending portion at the end of the guide plate 31, the coil can be bent into an acute-angle state under the abutment and limiting action of the guide bending portion, so that the protective film on the surface of the coil can be more easily separated from the coil through the large bending of the coil, thereby realizing the automatic separation of the protective film and the coil.

[0056] Example 5

[0057] See also Figure 1 、 Figure 2 As shown, the difference between this embodiment and the above embodiment is that the lifting drive assembly includes a lifting cylinder 32, which is fixedly mounted on the upper end of the frame 1, and a lifting frame 33 is fixedly mounted on the telescopic end at the bottom of the lifting cylinder 32. Both ends of the lifting frame 33 are mounted with elastic telescopic rods, and a support rod 37 is fixedly mounted between the two elastic telescopic rods. The pressure roller 38 is rotatably mounted on the surface of the support rod 37;

[0058] When rolling the film, the lifting cylinder 32 drives the elastic telescopic rod, the support rod 37 and the pressure roller 38 downward, so that the pressure roller 38 first abuts the left end of the protective film against the left end of the lens. Then, as the protective film and the lens move synchronously to the left under the pressure roller 38, the pressure roller 38 rolls the protective film to the lens surface.

[0059] Among them, the pressure roller 38 is connected to the lifting cylinder 32 through an elastic telescopic rod. When the lifting cylinder 32 drives the elastic telescopic rod and the pressure roller 38 downward, the pressure roller 38 can elastically abut against the lens under the elastic force of the elastic telescopic rod, thereby preventing the pressure of the pressure roller 38 from being too high and damaging the lens. When applying the film, the elastic telescopic rod can automatically adjust the height of the pressure roller 38 according to the curvature of the lens surface, so that the pressure roller 38 is always tightly pressed against the lens surface, which can improve the rolling and film applying effect of the pressure roller 38.

[0060] Furthermore, the elastic telescopic rod includes a suspension rod 35, which is slidably inserted into the end of the lifting frame 33. The top end of the suspension rod 35 extends above the lifting frame 33 and is fixedly mounted with a top plate 34. The bottom end of the suspension rod 35 is fixedly connected to the end of the support rod 37. The lower end of the suspension rod 35 is movably sleeved with a pressure spring 36 located between the lifting frame 33 and the support rod 37.

[0061] Among them, the top plate 34 abuts against the top surface of the lifting frame 33, supporting and limiting the suspension rod 35, pressure roller 38 and other mechanisms. When the lifting cylinder 32 drives the lifting frame 33 downward, the lifting frame 33 drives the suspension rod 35, pressure roller 38 and other mechanisms to move downward synchronously until the pressure roller 38 abuts against the protective film and the top surface of the lens. Then, as the lifting frame 33 continues to descend, the lifting frame 33 moves downward relative to the suspension rod 35, and presses the pressure spring 36 downward to be retracted, so that the pressure spring 36 generates an elastic force acting on the support rod 37 and the pressure roller 38, and through this elastic force, the pressure roller 38 elastically abuts against the protective film and the top surface of the lens, so that the pressure roller 38 rolls the protective film to fit the lens surface.

[0062] Example 6

[0063] See also Figures 1-6 、 Figure 9 、 Figure 10As shown, the difference between this embodiment and the above embodiment is that the film-sticking mechanism 3 also includes an adsorption positioning component located above the bending member, and the adsorption positioning component includes a movable lifting unit and a vacuum suction cup 311. The vacuum suction cup 311 can adsorb and reinforce the protective film when the protective film is separated from the coil to increase the rigidity of the protective film. The movable lifting unit can drive the vacuum suction cup 311 to move synchronously with the protective film and the coil; the movable lifting unit includes a guide groove 312 and a telescopic cylinder 314. The guide groove 312 is opened at the upper end of the frame 1 and is arranged parallel to the bending member. A limit seat 315 is slidably installed inside the guide groove 312, and the telescopic cylinder 314 is fixedly installed on the upper end of the frame 1, and the telescopic end of the telescopic cylinder 314 is fixedly connected to the outer end of the limit seat 315, and the inner end of the limit seat 315 is fixedly installed with a bracket 39 extending above the bending part; the top of the bracket 39 is fixedly installed with a suction cup driving cylinder 310, and the telescopic end of the suction cup driving cylinder 310 extends to the bottom of the bracket 39 and is fixedly installed with a connecting frame 313, and the vacuum suction cup 311 is fixedly installed on the front side end of the connecting frame 313;

[0064] Among them, the vacuum suction cup 311 is connected to the air pump. When the protective film is about to move to the guide bending part at one end of the guide plate 31 with the coil, the suction cup drives the cylinder 310 to drive the connecting frame 313 downward, so that the connecting frame 313 drives the vacuum suction cup 311 downward to abut the top surface of the protective film. At the same time, the air pump sucks the vacuum suction cup 311 so that the vacuum suction cup 311 is adsorbed on the top surface of the protective film to limit and reinforce the protective film. Then, the telescopic cylinder 314 drives the limiting seat 315 along the guide groove 312. Move to the left to drive the bracket 39, the connecting frame 313 and the vacuum suction cup 311 to move to the left synchronously with the protective film, so that the protective film can be transported normally. When the protective film is partially separated from the roll and begins to be applied, the air is ventilated into the vacuum suction cup 311 through the air pump to separate the vacuum suction cup 311 from the protective film. At the same time, the telescopic cylinder 314 and the suction cup driving cylinder 310 drive the vacuum suction cup 311 to move and reset, so that the vacuum suction cup 311 avoids the pressure roller 38, which facilitates the downward rolling of the pressure roller 38 to press the film.

[0065] Example 7

[0066] This embodiment discloses a method for applying film to swimming goggles, and the specific steps are as follows:

[0067] First, the coil with the protective film is synchronously wound and unwound by the winding and unwinding mechanism 2, so that the coil is pulled and conveyed by winding and unwinding. When the coil passes the end position of the bending member, the coil is bent under the abutment and limiting action of the bending member end. At this time, the protective film on the coil remains straight due to its own rigidity, so that the protective film and the coil are gradually separated. The separated protective film gradually extends below the pressure roller 38 as the coil moves.

[0068] Then, the winding and unwinding of the coil is stopped, so that the coil conveyance stops, and at the same time, the lenses of the swimming goggles are placed in the positioning grooves on the positioning fixture 42, and the positioning fixture 42 is driven by the translation drive unit to move to the bottom of the protective film;

[0069] The lifting drive assembly then drives the pressing roller 38 downward, pressing the protective film downward and onto the goggle lens. The reel 2 then drives the roll to continue moving and conveying, causing the protective film to continue separating from the roll and extending to the left. Simultaneously, the translation drive unit drives the positioning fixture 42 and the goggle lens to move synchronously to the left, and the pressing roller 38 gradually presses the protective film onto the goggle lens.

[0070] Until the protective film is completely attached to the goggle lens, the pressure roller 38 is driven upward and reset by the lifting drive assembly, and then the positioning fixture 42 and the goggle lens are driven by the translation drive unit to continue to move to the left and reset, and the goggle lens with the protective film attached to the positioning fixture 42 is removed. This process is repeated and the above steps can be continued to apply the film to the goggle lens.

8. A film-sticking method for swimming goggles, using the film-sticking device according to any one of claims 1 to 7, characterized in that: The specific steps are as follows: First, the coil with the protective film is synchronously wound and unwound by the winding and unwinding mechanism, so that the coil is pulled and conveyed by winding and unwinding. When the coil passes the end position of the bending part, the coil is bent under the abutment and limiting action of the bending part end. At this time, the protective film on the coil remains straight due to its own rigidity, so that the protective film and the coil are gradually separated. The separated protective film gradually extends below the pressure roller as the coil moves. Then, the winding and unwinding of the coil is stopped, so that the coil conveyance stops, and at the same time, the lens of the swimming goggle is placed in the positioning groove on the positioning fixture, and the positioning fixture is driven by the translation drive unit to move to the bottom of the protective film; Then, the lifting drive assembly drives the pressing roller downward, so that the pressing roller presses the protective film down and adheres it to the goggle lens. Then, the reel is driven by the reeling and unreeling mechanism to continue to move and convey the material, so that the protective film continues to separate from the material and extend to the left. At the same time, the translation drive unit drives the positioning fixture and the goggle lens to move synchronously to the left, and the pressing roller gradually rolls the protective film onto the goggle lens. Until the protective film is completely attached to the goggle lens, the pressure roller is driven upward and reset by the lifting drive assembly, and then the positioning fixture and the goggle lens are driven to move to the left and reset by the translation drive unit, and the goggle lens with the protective film attached to the positioning fixture is removed. This process is repeated back and forth, and the goggle lens can be continuously filmed.
