DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figures 1 to 6 The present invention provides a technical solution: a glass panel protective film positioning device, comprising a base 23, the inner bottom of the base 23 is connected to a support mechanism for placing a glass panel body 19, the upper part of the base 23 is fixedly connected to a mounting frame 31, and the inner bottom of the mounting frame 31 is connected to a roller mechanism that can smooth the protective film coated on the upper surface of the glass panel body 19 when the glass panel body 19 moves upward;

[0030] The roller mechanism includes two fixed rods 28, each fixed rod 28 is rotatably mounted with a mounting shaft 34 at the lower part, and the two ends of the mounting shaft 34 are respectively fixedly connected with swing rods 30, and the rollers 20 are rotatably mounted on the side walls of the two swing rods 30 near the bottom, and the two ends of each swing rod 30 are respectively provided with triangular teeth 17 that can be engaged when the swing rod 30 rotates, and each swing rod 30 is respectively fixedly connected with a fixing bar 21, and the ends of the two fixing bars 21 away from the mounting shaft 34 are rotatably connected with the first connecting rod 18;

[0031] The mounting frame 31 is connected to a driving mechanism for moving the glass panel body 19 upward, and the driving mechanism is connected to a first transmission mechanism for rotating the mounting shaft 34 .

[0032] Through the action of the set pressure roller mechanism and the driving mechanism, on the one hand, the two swing rods 30 can be driven to swing in an arc shape, so that the roller 20 at the lower part of the swing rod 30 can swing in an arc shape to both sides. On the other hand, the glass panel body 19 is continuously raised, and the roller 20 swings in an arc shape to both sides by utilizing the extrusion between the two, so that the protective film is smoothed to both sides, thereby reducing the presence of air bubbles and improving the flatness of the film.

[0033] Furthermore, the support mechanism includes four mounting columns 13, and a support plate 16 is slidably installed between the four mounting columns 13. A limit block is fixedly installed on the top of each mounting column 13, and a spring 12 is connected to the outer wall of the mounting column 13 between each limit block and the support plate 16.

[0034] When the push rod 1 drives the pressure plate 32 to move downward, the support plate 16 and the glass panel body 19 on its upper surface can be further moved upward and the spring 12 can be in a compressed state. When the push rod 1 drives the pressure plate 32 to move upward, the support plate 16 is reset under the elastic force of the spring 12.

[0035] Furthermore, the driving mechanism includes a push rod 1, which is slidably mounted on the top of the mounting frame 31 through a through hole, and a pressure plate 32 is fixedly connected to the bottom of the push rod 1. Two first fixed pulleys 3 and two second fixed pulleys 29 are also fixed to the inner top of the mounting frame 31. Both ends of the pressure plate 32 are respectively fixedly connected with connecting ropes 5, and each connecting rope 5 passes through the first fixed pulley 3 and the second fixed pulley 29 in turn and extends to the upper surface of the support plate 16 and is fixed thereto.

[0036] By manually pressing the push rod 1, the pressure plate 32 moves downward as a whole. On the one hand, due to the tension of the connecting rope 5, when the push rod 1 drives the pressure plate 32 to move downward, the support plate 16 and the glass panel body 19 on its upper surface can be further moved upward.

[0037] Furthermore, the first transmission mechanism includes two racks 33 , which are fixedly connected to the lower surface of the pressing plate 32 , respectively. The outer wall of each mounting shaft 34 is fixedly connected with a gear 35 meshing with the rack 33 .

[0038] The downward movement of the pressure plate 32 causes the rack 33 to begin to mesh with the gear 35, thereby driving the mounting shaft 34 to rotate counterclockwise, and in conjunction with the connection of the first connecting rod 18, driving the two swing rods 30 to swing in an arc shape.

[0039] Furthermore, the inner wall of the mounting frame 31 is also connected to a pressing frame mechanism for further compacting the surroundings after the protective film is smoothed. The pressing frame mechanism includes two connecting plates 9. Both connecting plates 9 are slidably mounted with L-shaped movable rods 10 through through holes. A pressing frame 15 is connected between the two L-shaped movable rods 10. The upper surfaces of the two connecting plates 9 are connected to a second transmission mechanism for pressing the pressing frame 15 downward after the roller 20 is smoothed.

[0040] Through the action of the second transmission mechanism and the pressure frame 15, when the L-shaped movable rod 10 slides downward, the pressure frame 15 can be further driven to slide downward. Through the height setting of the pressure frame 15, when the smoothing of the roller 20 is about to be completed, the pressure frame 15 moves downward and flattens the surrounding areas of the protective film and is sleeved on the lower part of the glass panel body 19. This process can further improve the quality of the film.

[0041] Furthermore, the second transmission mechanism includes two slide rails 26, which are respectively fixedly connected to the upper surface of the connecting plate 9, and a slider 24 is slidably installed inside each slide rail 26. A second connecting rod 25 is rotatably installed on one end of the slider 24, and a third connecting rod 27 is rotatably installed on the end of the second connecting rod 25 away from the slider 24. The end of the third connecting rod 27 away from the second connecting rod 25 is fixedly connected to the mounting shaft 34, and the other end of the slider 24 is fixedly connected to a movable plate 6, and a limiting groove 7 is provided on the movable plate 6. A limiting block is fixedly connected to the front side of the L-shaped movable rod 10, and the limiting block is slidably installed inside the limiting groove 7.

[0042] Due to the connection between the slide rail 26 and the third connecting rod 27, the slider 24 can be further driven to move inside the slide rail 26 toward the end away from the pressure plate 32. At this time, the movable plate 6 can be further driven to move. Due to the setting of the limit groove 7 and the limit block, the L-shaped movable rod 10 can be further driven to slide downward.

[0043] Furthermore, a blowing plate 4 for blowing air to the surface of the protective film is connected between the two swing rods 30 , and a fan 11 for supplying air to the blowing plate 4 is fixed to the side wall of the base 23 .

[0044] By setting the fan 11, at the beginning, the fan 11 is connected to the blowing plate 4. Since the blowing plate 4 is set on the opposite sides of the two rocker arms 30 and located on the upper part of the roller 20, when the rocker arm 30 swings, the blowing effect of the blowing plate 4 can pre-smooth the protective film, which can further improve the efficiency and quality of film pasting.

[0045] Furthermore, the mounting frame 31 is also provided with a hot air mechanism for rapid thermoplastic molding of the compacted protective film. The hot air mechanism includes a blowing frame 14 fixed to the upper part of the base 23 , and the inner wall of the blowing frame 14 is fixedly connected with a heating net 22 .

[0046] Through the heating of the heating net 22 and the blowing action of the blowing frame 14, the protective film can be thermoformed on the side wall of the glass panel body 19, thereby further improving the sealing between the glass panel and the protective film and improving the film pasting quality.

[0047] Furthermore, a contact block 8 for sensing compaction around the protective film is fixedly connected to the inner wall of the mounting frame 31 close to the fan 11 , and the contact block 8 and the movable plate 6 are on the same horizontal plane.

[0048] Through the contact block 8, when the frame 15 moves downward and flattens the surrounding of the protective film and is sleeved on the lower part of the glass panel body 19, the movable plate 6 squeezes the contact block 8, the contact block 8 receives the signal, the single-chip microcomputer controls the heating network 22 to work, and the fan 11 is connected to the blowing frame 14.

[0049] Furthermore, a limiting bar 2 for limiting the height of the push rod 1 is rotatably mounted on the top of the mounting frame 31 .

[0050] By setting the limit strip 2, the height of the push rod 1 after being pressed down can be fixed and limited.

[0051] Working principle: When using the glass panel protective film positioning device, the glass panel body 19 to be laminated is placed on the upper surface of the support plate 16, and the protective film to be laminated is placed on the upper surface of the glass panel body 19. First, the push rod 1 is manually pressed to make the pressing plate 32 move downward as a whole. At the beginning, due to the pulling force of the connecting rope 5, when the push rod 1 drives the pressing plate 32 downward, the supporting plate 16 and the glass panel body 19 on its upper surface can be further moved upward and the spring 12 can be compressed. Afterwards, when the supporting plate 16 rises to a certain height, the downward movement of the pressing plate 32 can make the rack 33 start to mesh with the gear 35, thereby driving the mounting shaft 34 to rotate counterclockwise, and in conjunction with the connecting action of the first connecting rod 18, the two swing rods 30 are driven to swing in an arc, so that the roller 20 at the lower part of the swing rod 30 swings in an arc to both sides, and in conjunction with the continuous rise of the glass panel body 19, the roller 20 swings in an arc to both sides by using the extrusion between the two, so that the protective film is smoothed to both sides.

[0052] Through the second transmission mechanism and the pressing frame 15, when the roller 20 swings, due to the connection between the slide rail 26 and the third connecting rod 27, the slider 24 can be further driven to move inside the slide rail 26 toward the end away from the pressing plate 32. At this time, the movable plate 6 can be further driven to move. Due to the setting of the limit groove 7 and the limit block, the L-shaped movable rod 10 can be further driven to slide downward. Through the height setting of the pressing frame 15, when the roller 20 is about to finish smoothing, the pressing frame 15 moves downward and flattens the surroundings of the protective film and is sleeved on the lower part of the glass panel body 19.

[0053] By setting the fan 11, at the beginning, the fan 11 is connected with the blowing plate 4. Since the blowing plate 4 is arranged on the opposite sides of the two swing rods 30 and located on the upper part of the roller 20, when the swing rod 30 swings, the blowing effect of the blowing plate 4 can pre-smooth the protective film;

[0054] And through the contact block 8, when the pressure frame 15 moves downward and flattens the surroundings of the protective film and is sleeved on the lower part of the glass panel body 19, the movable plate 6 squeezes the contact block 8, the contact block 8 receives the signal, the single-chip microcomputer controls the heating network 22 to work, and the fan 11 is connected with the blowing frame 14. Through the heating of the heating network 22 and the blowing action of the blowing frame 14, the surroundings of the protective film can be thermoplasticized on the side wall of the glass panel body 19.

[0055] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
