Description

Technical Field

[0001] The invention relates to the technical field of film peeling machines, and in particular to an automatic film peeling machine for a mobile phone middle frame. Background Art

[0002] The mobile phone middle frame usually refers to an intermediate component structure of the mobile phone. It is a bridge between the components that connect and support the screen and the back of the mobile phone. In the process of assembling a mobile phone, the middle frame is an extremely important component. Usually, its surface needs to be protected to prevent scratches or damage during transportation or assembly. The existing protection method is to stick a protective film around the polished mobile phone middle frame.

[0003] The mobile phone middle frame with film pasted on all sides needs to remove the protective film in some areas to be processed. There are two existing ways to remove the film, one is manual film removal and the other is automatic film removal. The manual film removal method consumes a lot of manpower and is inefficient. The existing automatic film removal method uses mechanical positioning to determine the starting point. The control system will instruct the film removal tool (such as a suction cup) to move to the positioning position, and then use the mechanical arm to cooperate with the film removal tool to absorb the protective film at the starting point, and continuously tear off the protective film according to the predetermined path and speed;

[0004] However, in this process, since the outer wall of most existing mobile phone middle frames has a certain curvature, the protective film is wrapped around it and fits with the outer wall of the middle frame, forming a certain curvature, and the existing suction cup film tearing tool has difficulty in grabbing the non-planar protective film.

[0005] To this end, we propose an automatic mobile phone middle frame automatic film tearing machine. Summary of the invention

[0070] 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.

[0071] Example 1: Please refer to Figure 1-18 The present invention provides an automatic mobile phone middle frame automatic film tearing machine, comprising:

[0072] A base 10, to which a track frame 11 is fixedly connected, and a placement platform 12 is fixedly connected to the top of the base 10, and the placement platform 12 is used to place a mobile phone middle frame;

[0073] A three-dimensional moving mechanism 20, wherein the three-dimensional moving mechanism 20 is disposed on the track frame 11, and two groups of the three-dimensional moving mechanism 20 are symmetrically disposed about the vertical center plane of the track frame 11;

[0074] The contact mechanism 30 is arranged at the lower side of the three-dimensional moving mechanism 20. The contact mechanism 30 is symmetrically arranged in two groups about the vertical center plane of the track frame 11. The contact mechanism 30 includes:

[0075] A circular plate 31, which is arranged at one side of the three-dimensional moving mechanism 20, has a sliding groove in the circular plate 31, a slider 32 is slidably connected in the circular plate 31, a circular groove plate 33 is fixedly connected to one side of the slider 32, a connecting belt 34 is rotatably connected to the outer wall of the circular groove plate 33, a rotating mechanism 36 is arranged in the circular plate 31, and the rotating mechanism 36 is used to drive the connecting belt 34 to rotate;

[0076] It should be noted that, by placing the middle frame of the mobile phone with the film to be torn off on the placement table 12, and moving it to the gap between the middle frame of the mobile phone and the protective film through the three-dimensional moving mechanism 20 and the contact mechanism 30, the three-dimensional moving mechanism 20 drives the slider 32 to move downward, and then the circular groove plate 33 is inserted into the gap between the middle frame of the mobile phone and the protective film. During the insertion process, the connecting belt 34 is driven by the rotating mechanism 36 to rotate in the direction opposite to the insertion direction, so that the connecting belt 34 is in a relatively static state with the film during the process of peeling off the film and moving downward, thereby reducing the friction force on the protective film during insertion, avoiding deformation of the protective film to a certain extent, and facilitating the next operation.

[0077] A top film mechanism 40, which is disposed on the lower side of the circular groove plate 33, and is used to lift up the protective film and attach it to the surface of the connecting belt 34. Two groups of the top film mechanism 40 are symmetrically disposed about the circular groove plate 33;

[0078] A clamping mechanism 50, which is disposed on the circular groove plate 33 and is used to cooperate with the connecting belt 34 to fix the protective film;

[0079] Positioning components 60, the positioning components 60 are symmetrically arranged on both sides of the base 10;

[0080] It should be noted that, after placing the mobile phone middle frame on the placement table 12, the positioning component 60 is used to quickly correct the mobile phone middle frame and fix it in the specified position, thereby facilitating the film tearing operation. If the exposed height of the protective film on the outer side of the mobile phone middle frame is less than three millimeters, the three-dimensional moving mechanism 20 can drive the top film mechanism 40 on the lower side of the circular groove plate 33 to first insert into the gap between the mobile phone middle frame and the protective film, and the protective film is picked up and attached to the connecting belt 34 through the top film mechanism 40. At the same time, the top film mechanism 40 cooperates with the clamping mechanism 50 to fix the protective film. In this way, the top film mechanism 40 can accurately and easily pick up the protective film and attach it to the connecting belt 34, and cooperate with the clamping mechanism 50 to easily grab the film on the edge of the mobile phone middle frame.

[0081] The rotating mechanism 36 comprises:

[0082] A gear 361, one side of which is fixedly connected to a roller member 362, the roller member 362 is rotatably connected to the circular groove plate 33, the outer wall of the roller member 362 is in contact with the inner wall of the connecting belt 34, the gear 361 is rotatably connected to the slider member 32, the inner wall of the circular plate member 31 is fixedly connected to a rack 363, the rack 363 is meshed with the gear 361, the circular groove plate 33 is gradually reduced in width from top to bottom, and the cross-sectional shape of the circular groove plate 33 is a water drop shape;

[0083] It should be noted that, in the process of the slider member 32 moving downward along the circular plate member 31, the gear 361 moves accordingly, the gear 361 cooperates with the rack 363 to drive the roller member 362 to rotate, and the roller member 362 drives the connecting belt 34 to rotate along the surface of the circular groove plate 33. By designing the cross-section of the circular groove plate 33 to be teardrop-shaped, the circular groove plate 33 and the connecting belt 34 are slowly stretched open when they just come into contact with the protective film. During the continued insertion process, the movement direction of the connecting belt 34 is opposite to the insertion direction, so that the protective film will not be displaced in the vertical direction during the stretching process.

[0084] The top film mechanism 40 comprises:

[0085] A cross bar 41, the end of which is rotatably connected to the circular groove plate 33, the end of which is rotatably connected to the cross bar 41 away from the circular groove plate 33 is connected to a lifting member 42, the end of which is located on one side of the cross bar 41 and fixedly connected to a connecting rod 43, a vortex spring 44 is provided on the connecting rod 43, one end of which is fixedly connected to the outer wall of the connecting rod 43, the other end of which is fixedly connected to the inner wall of the cross bar 41, a limiting groove 45 is provided on the cross bar 41, a limiting block 46 is provided in the limiting groove 45, the limiting block 46 is fixedly connected to the end of the connecting rod 43, the cross bar 4 A second connecting rod 47 is fixedly connected to one end of the circular groove plate 33, and the second connecting rod 47 is symmetrically arranged with respect to the cross bar 41. A second vortex spring 48 is arranged on the outer wall of the second connecting rod 47, and one end of the second vortex spring 48 is fixedly connected to the outer wall of the second connecting rod 47, and the other end of the second vortex spring 48 is fixedly connected to the inner wall of the lifting member 42. A second limiting groove 49 is provided on one side of the lifting member 42, and a second limiting block 491 is arranged in the second limiting groove 49. The second limiting block 491 is fixedly connected to the second connecting rod 47. A rotating assembly 70 is arranged on one side of the circular groove plate 33, and the rotating assembly 70 is used to pull the lifting member 42 obliquely upward from the bottom thereof;

[0086] It should be noted that, in the initial state, the cross bar 41 and the lifting member 42 are L-shaped, and the cross bar 41 and the lifting member 42 are inserted downward along the gap between the mobile phone middle frame and the protective film through the three-dimensional translation mechanism 20. When the lifting member 42 is immersed in the protective film, the cross bar 41 and the lifting member 42 are driven by the three-dimensional translation mechanism 20 to pull the protective film outward, so that the upper protective film is separated from the mobile phone middle frame, and then the lifting member 42 is driven by the rotating component 70 to rotate along the cross bar 41 connecting rod 2 47 as the center of the circle. At the same time, when the lifting member 42 is When 42 turns to a certain angle, the cross bar 41 rotates with the connecting rod 43 on the circular groove plate 33 as the center, and finally the lifting piece 42 is fitted with the cross bar 41 and is in a tilted downward state. At the same time, in this process, the three-dimensional translation mechanism 20 drives the circular groove plate 33 to move slowly downward, and the lifting piece 42 uses its front end to hook the protective film and prop up and attach the protective film to the protective film during the downward movement. In this way, the circular groove plate 33 can maintain a certain distance from the middle frame of the mobile phone while grabbing the protective film, thereby avoiding damage to the outer wall of the middle frame of the mobile phone.

[0087] The arc angle of the first limiting groove 45 is between fifty-five and sixty degrees, and the arc angle of the second limiting groove 49 is ninety degrees;

[0088] It should be noted that by setting the arc of the limit groove 1 45 to between fifty-five and sixty degrees and the arc of the limit groove 2 49 to ninety degrees, the lifting member 42 can be reversed ninety degrees under the pull of the rotating component 70 and be flush with the cross bar 41, and the cross bar 41 can be rotated between fifty-five and sixty degrees along the connecting rod 1 43 on the circular groove plate 33. When the cross bar 41 and the lifting member 42 are finally tilted downward and can cooperate with the connecting belt 34 to grab the protective film upward by friction, the protective film can pass through the surface of the lifting member 42 tilted downward and reach the connecting belt 34, thereby preventing the lower end of the circular groove plate 33 from puncturing the protective film.

[0089] The rotating assembly 70 includes:

[0090] A drawstring member 71, one end of which is fixedly connected to the end of the lifting member 42, a motor fixing frame 72 is fixedly connected to the outer wall of the slider member 32, a micro motor 73 is fixedly connected to the end of the motor fixing frame 72 away from the slider member 32, a dumbbell member 74 is fixedly connected to the end of the internal rotating shaft of the micro motor 73, and the end of the drawstring member 71 away from the lifting member 42 is fixedly connected to the outer wall of the dumbbell member 74;

[0091] It should be noted that the dumbbell member 74 is driven to rotate by the internal rotating shaft of the micro motor 73, and the dumbbell member 74 can pull the drawstring member 71, so that the drawstring member 71 is wound around the dumbbell member 74, and the drawstring member 71 drives the lifting member 42 and the cross bar 41 to rotate, so that the protective film can be wrapped on the connecting belt 34;

[0092] It is worth noting that in the initial state, the drawstring member 71 is in a relaxed state. When the cross bar 41 and the lifting member 42 are driven by the three-dimensional translation mechanism 20 to be inserted along the gap between the protective film and the middle frame of the mobile phone, the top edge of the protective film will push the drawstring member 71 inside the cross bar 41 and the lifting member 42 upward, so that the drawstring member 71 fits with the inner wall of the cross bar 41 and the lifting member 42. Continuing to insert downward can make the top of the protective film stacked on the bottom wall of the cross bar 41, and then the micro motor 73 drives the drawstring member 71 to wrap around During the process of the dumbbell member 74, the pull belt member 71 is in a straightened state, and the pull belt member 71, the cross bar member 41 and the lifting member 42 form a triangle, and the pull belt member 71 brings the protective film in the cross bar member 41 and the lifting member 42 outward. As the micro motor 73 rotates, the pull belt member 71 cooperates with the lifting member 42 and the cross bar member 41 to wrap the protective film on the connecting belt 34. In this way, the pull belt member 71 cooperates with the lifting member 42 to form a larger contact surface with the protective film, thereby preventing the lifting member 42 from piercing the protective film;

[0093] The retaining member 75 is fixedly connected to the cross bar 41 and is L-shaped. The L-shaped retaining member 75 can prevent the drawstring member 71 from being displaced out of the cross bar 41 during the process of retracting and releasing.

[0094] The drawstring member 71 comprises:

[0095] An elastic portion 711, one end of which is fixedly connected to a non-elastic portion 712, the elastic portion 711 is made of rubber, and the thickness of the elastic portion 711 gradually increases in a direction away from the non-elastic portion 712;

[0096] It should be noted that, when the non-elastic part 712 pulls the elastic part 711, since the thickness of the elastic part 712 gradually increases in the direction away from the non-elastic part 712, the stretching distance of the unit size of the thinner section of the elastic part 712 close to the non-elastic part 712 during the stretching process is equivalent to the stretching distance of the unit size of the thicker section. Therefore, the elastic part 712 can use the friction force on its surface to drive the protective film stacked in the cross bar 41 to move along the stretching direction during the stretching process, and then cooperate with the lifting member 42 and the cross bar 41 to quickly wrap the protective film on the connecting belt 34.
