Manual film pasting is prone to inaccurate positioning, resulting in deviation and crooked pasting of the advertising film, and bubbles are easily generated during the manual film pasting process. The advertising film is easily scratched or even torn in the process of squeezing out the bubbles with a scraper, which ultimately leads to problems such as unstable effect, low efficiency, poor quality, and high scrap rate of manual film pasting.

For example, a first connecting rod may be referred to as a second connecting rod, and similarly, a second connecting rod may also be referred to as a first connecting rod, without departing from the scope of protection of this application.

[0038] The embodiment of the present invention provides an automatic film sticking device, such as Figure 1 As shown, it includes a bracket 1 and a connecting rod assembly, a ventilation pipe group and a driving mechanism arranged in the bracket 1, wherein the bracket 1 is formed with an opening for adsorbing the film 20 or pasting the film 20 to make way; the connecting rod assembly includes a first connecting rod 21 and a second connecting rod 22 respectively arranged at both ends of the bracket 1, and a movable rod 23 arranged close to the second connecting rod 22, the first connecting rod 21 and the second connecting rod 22 are respectively provided with a first through hole group 211 and a second through hole group 221 arranged in the same direction as the opening, the first connecting rod 21 and the second connecting rod 22 are on the same side of the adsorbent film 20 through the first through hole group 211 and the second through hole group 221, and the movable rod 23 is provided with a third through hole group for adsorbing the other side of the film 20 231; the ventilation pipe group includes a first ventilation pipe 212, a second ventilation pipe 222 and a third ventilation pipe 232 which are respectively arranged in the first connecting rod 21, the second connecting rod 22 and the movable rod 23, so that the first connecting rod 21, the second connecting rod 22 and the movable part absorb air through the first through hole group 211, the second through hole group 221 and the third through hole group 231 respectively to adsorb the membrane 20; the driving mechanism includes a first driving mechanism that drives the second connecting rod 22 and the movable rod 23 to approach the first connecting rod 21, and a second driving mechanism that drives the movable rod 23 to rotate. The membrane 20 is torn and pasted under the adsorption and rotation of the movable rod 23 and the approach of the movable rod 23 and the second connecting rod 22 to the first connecting rod 21.

[0039] Preferably, the second connecting rod 22 is provided with a first plane 223 on the side of the opening facing the bracket 1, and a second plane 224 is provided on the side of the first plane 223 of the second connecting rod 22 close to the first connecting rod 21, and the second plane 224 is extended in a direction away from the opening of the bracket 1, and the second through hole group 221 is provided on the first plane 223 and the second plane 224. The first plane 223 is close to the refrigerator 10 to make the advertising film close, and the second through hole group 221 on the second plane 224 can blow air to eliminate bubbles when the advertising film is applied.

[0040] The first through hole group 211 and the second through hole group 221 on the first connecting rod 21 and the second connecting rod 22 are arranged in the same direction as the opening of the bracket 1. When the first connecting rod 21 and the second connecting rod 22 inhale air through the first vent pipe 212 and the second vent pipe 222, the two ends of the film 20 can be adsorbed. The movable rod 23 is adsorbed on the other side of the film 20 through the third vent pipe 232. The film 20 is provided with two layers before pasting, one layer of advertising film for pasting and the isolation film attached to the side of the pasting surface of the advertising film. Before pasting the film 20, the isolation film needs to be torn off to achieve pasting. The other side of the adsorbed film 20 by the movable rod 23 is actually an adsorbed isolation film. At one end of the second connecting rod 22, the two sides of the film 20 are adsorbed by the second connecting rod 22 and the movable rod 23 respectively, so that the isolation film and the advertising film at this end of the film 20 can be torn off.

[0041] The second driving mechanism drives the movable rod 23 to rotate, so that the isolation film can be wound on the movable rod 23. The first driving mechanism drives the second connecting rod 22 and the movable rod 23 to approach the first connecting rod 21, so that the film 20 can be torn and pasted at the same time.

[0042] Specifically, Figure 3 As shown, in this embodiment, the first connecting rod 21 is arranged at the upper end of the bracket 1, and the second connecting rod 22 and the movable rod 23 are arranged at the lower end of the bracket 1, so the film 20 is pasted from bottom to top. For ease of understanding, the following description takes the end where the opening is located as the front end.

[0043] Figure 4 In the embodiment, guide rails 31 and sliding plates 32 slidably connected to the guide rails 31 are provided on both sides of the bracket 1 adjacent to the opening. The guide rails 31 extend in the height direction of the bracket 1. The second connecting rod 22 and the movable rod 23 are connected to the sliding plate 32. The sliding plate 32 is fixed to a slider 321. The slider 321 slides in the extension direction of the guide rail 31. The first driving mechanism includes a first gear 41 rotatably connected to the sliding plate 32, a rack 42 extending in the length direction of the guide rail 31, and a first motor 43 driving the first gear 41 to rotate. The first gear 41 is meshed with the rack 42. The first motor 43 drives the first gear 41 to rotate. The first gear 41 rotates and moves in the extension direction of the rack 42 under the action of the meshing of the teeth, thereby driving the sliding plate 32 to move in the length direction of the guide rail 31, so that the second connecting rod 22 and the movable rod 23 approach the direction of the first connecting rod 21.

[0044] To ensure the stability of the movement of the sliding plate 32, first driving mechanisms are provided at both the front and rear ends of the sliding plate 32 for synchronous adjustment, and racks 42 are provided at the edges of the front and rear side walls.

[0045] Furthermore, the sliding plate 32 is provided with a first track 322, and both ends of the movable rod 23 pass through the first track 322 and move in the first track 322. The automatic film laminating device is also provided with a swing rod 61 rotatably connected to the sliding plate 32, one end of the swing rod 61 is rotatably connected to the sliding plate 32, and the other end is connected to the movable rod 23, and the swing rod 61 rotates to drive the movable rod 23 to move in the first track 322.

[0046] In this embodiment, the swing rod 61 is a rod with a fixed length, so the first track 322 on the sliding plate 32 is an arc with one end taking the connection between the swing rod 61 and the sliding plate 32 as the center and the distance between the connection between the swing rod 61 and the sliding plate 32 and the connection point between the swing rod 61 and the movable rod 23 as the radius. Of course, the swing rod 61 can also be a rod with a variable length, and the first track 322 can be a non-circular arc. The arc-shaped first track 322 protrudes toward the front end, that is, in the front-to-back direction, the middle part of the arc-shaped first track 322 is forward and the two ends are backward, the two ends are respectively higher and lower than the position of the second connecting rod 22, and the middle part is forward relative to the second connecting rod 22, that is, closer to the opening of the bracket 1, which makes the connection between the swing rod 61 and the sliding plate 32 at the rear side of the second connecting rod 22, that is, farther away from the opening of the bracket 1.

[0047] When the movable rod 23 moves in the first track 322, it includes moving to the preparatory position at the lower end of the first track 322, moving to the adsorption position in the middle of the first track 322 flush with the second connecting rod 22, and moving to the tearing position at the upper end of the first track 322. When the movable rod 23 is in the preparatory position, it waits for the film 20 to be adsorbed by the first connecting rod 21 and the second connecting rod 22. After the two ends of the film 20 are respectively adsorbed by the first connecting rod 21 and the second connecting rod 22, the swing rod 61 drives the movable rod 23 to move to the adsorption position in the first track 322. The movable rod 23 adsorbs the isolation film on the back of the advertising film. The swing rod 61 continues to drive the movable rod 23 to move to the upper end of the first track 322 to the tearing position, and tears the isolation film and the lower end of the advertising film before continuing the next step of the film sticking 20 operation.

[0048] Furthermore, the second driving mechanism includes a second gear 51 mounted on both ends of the movable rod 23, a third gear 52 meshing with the second gear 51, and a second motor 53 driving the third gear 52 to rotate. The second motor 53 is connected to the rocker arm 61, so that the movable rod 23 can rotate along its own axis while being driven by the rocker arm 61 to move in the first track 322. After the second connecting rod 22 and the movable rod 23 cooperate to tear off the advertising film and the isolation film, the second motor 53 drives the movable rod 23 to rotate, so that the isolation film can be wrapped around the movable rod 23.

[0049] Preferably, a third motor 62 is provided at the connection between the swing rod 61 and the sliding plate 32 to drive the swing rod 61 to rotate.

[0050] Further, such as Figure 5 As shown, the automatic film laminating equipment also includes an adjusting mechanism for adjusting the movement of the first connecting rod 21, and the adjusting mechanism includes a first fixed block 71 and a second fixed block 72 fixed to the bracket 1 and spaced apart, a guide rod 73 connected between the first fixed block 71 and the second fixed block 72, a sliding block 74 sliding along the length direction of the guide rod 73, a first elastic member 75 connected between the first fixed block 71 and the sliding block 74, and a second elastic member 76 connected between the second fixed block 72 and the sliding block 74, wherein the guide rod 73 extends along the height direction of the bracket 1, and the first connecting rod 21 is connected to the sliding block 74. When the sliding block 74 or the first connecting rod 21 is subjected to an external force, it moves along the extension direction of the guide rod 73, and can be restored under the elastic force of the first elastic member 75 and the second elastic member 76 when the external force is lost.

[0051] In order to make room for the sliding plate 32 that moves up and down, the adjustment mechanism is arranged on the outer side surfaces of the bracket 1 adjacent to the opening on both sides, so that the outer side surfaces are provided with second tracks 11 along the extending direction of the guide rod 73 to make room for the first connecting rod 21. In this embodiment, the first elastic member 75 and the second elastic member 76 are both springs, which are arranged beside the guide rod 73. Of course, the springs can also be sleeved on the guide rod 73.

[0052] Furthermore, the adjustment structure also includes a first magnetic member arranged on the second fixed block 72 near the sliding block 74, a second magnetic member arranged on the sliding block 74 near the second fixed block 72, and a gravity hammer 81 connected to the first magnetic member. The first magnetic member and the second magnetic member are arranged in the second fixed block 72 and the sliding block 74 respectively, which are not shown in the figure. The gravity hammer 81 is connected to the first magnetic member through a connecting rod 82 with a non-circular cross-section, which is a regular hexagon in this embodiment. Figure 5 and Figure 8 As shown, a connection block 83 is arranged between the gravity hammer 81 and the first magnetic member, a limit block is arranged inside the connection block 83, and the outer periphery of the limit block cross section and the inner periphery of the connection block 83 cross section are matched to form a circle, so that the limit member 84 and the connection block 83 can rotate relative to each other. A limit protrusion 831 is arranged on the inner periphery of the connection block 83, and a limit groove 841 is arranged on the outer periphery of the limit member 84 corresponding to the limit protrusion 831. The limit protrusion 831 and the limit groove 841 cooperate to limit the rotation angle α between the limit member 84 and the connection block 83.

[0053] The limit block forms a through hole that matches the cross-section of the connecting rod 82, so that the limit block is sleeved on the connecting rod 82. In this embodiment, when the bracket 1 is set vertically, the gravity hammer 81 is set horizontally, and the end with greater gravity, that is, the big head of the gravity hammer 81 in the figure, is higher. When the bracket 1 is placed horizontally, the gravity hammer 81 rotates counterclockwise under the action of gravity until the big head end is facing the first connecting rod 21 of the bracket 1, and at the same time drives the magnetic pole of the first magnetic part to rotate through the connecting rod 82.

[0054] The present embodiment is configured such that when the bracket 1 is horizontally arranged, the magnetic poles of the first magnetic component are offset from the magnetic poles of the second magnetic component, and the magnetic attraction between the two is lost; when the bracket 1 is vertically arranged, under the limitation of the limiting groove 841 of the limiting component 84 and the limiting protrusion 831 of the connecting block 83, the magnetic pole direction of the first magnetic component is rotated 70° and then attracted to the second magnetic component by opposite sex, thereby driving the sliding block 74 and the first connecting rod 21 connected to the sliding block 74 to approach the second fixing component.

[0055] Furthermore, the automatic film sticking device further includes a mechanical arm 9, which is connected to the side directly away from the outlet, and the bracket 1 moves and rotates under the action of the mechanical arm 9. In addition, the mechanical arm 9 provides gas, program control, etc. to the bracket 1 and the ventilation pipes arranged thereon. The specific operation of the automatic film sticking device is as follows:

[0056] First, the refrigerator 10 or the like to be pasted with the film 20 needs to be transported to the designated position, and the mechanical wall acts on the bracket 1 to make it reach the fixed placement position of the film 20. At this time, the bracket 1 is placed horizontally, and the gravity hammer 81 drives the magnetic pole of the first magnetic part to rotate under the action of gravity, so that the first magnetic part and the second magnetic part attract each other, and drive the sliding block 74 and the first connecting rod 21 to move in the direction close to the second connecting rod 22. At the same time, the third motor 62 drives the swing rod 61 to drive the movable rod 23 to move to the preparatory position, and the swing rod 61 rotates about 80 degrees, and then controls the first ventilation pipe 212 and the second ventilation pipe 222 to inhale, so that the two ends of the film 20 are adsorbed on the first connecting rod 21 and the second connecting rod 22.

[0057] After the film 20 is adsorbed, the mechanical arm 9 acts on the bracket 1 to make the bracket 1 vertical, and the gravity hammer 81 rotates under the action of gravity, driving the magnetic pole of the first magnetic member to rotate, and the magnetic attraction between the first magnetic member and the second magnetic member is lost. The sliding block 74 moves in the direction away from the second connecting rod 22 under the elastic force of the first elastic member 75 and the second elastic member 76, and the first connecting rod 21 moves away from the second connecting rod 22, thereby tightening the film 20. Later, the third motor 62 drives the swing rod 61 to drive the movable rod 23 to move to the adsorption position, and the swing rod 61 rotates about 40°. At this time, the movable rod 23 is located on the side of the film 20 away from the first connecting rod 21 and the second connecting rod 22, and the third ventilation pipe 232 in the movable rod 23 is controlled to inhale air. The two sides of the lower end of the film 20 are adsorbed by the second connecting rod 22 and the movable rod 23 respectively. The third motor 62 continues to drive the swing rod 61 to drive the movable rod 23 to move to the tearing position, and the swing rod 61 rotates about 40°. The advertising film and the isolation film are torn under the adsorption of the second connecting rod 22 and the movable rod 23. When the movable rod 23 moves from the adsorption position to the tearing position, the second motor 53 drives the movable rod 23 to rotate, that is, the movable rod 23 tears the isolation film while winding and collecting the isolation film.

[0058] After the lower end of the film 20 is torn, the robotic arm 9 moves the bracket 1 so that the lower end of the advertising film is attached to the refrigerator 10, and then the first ventilation pipe 212 is switched to exhaust to apply pressure to the advertising film so that the advertising film is attached to the refrigerator 10. After the lower end of the advertising film is attached to the cabinet, the first motor 43 drives the first gear 41 to rotate, driving the sliding plate 32 and the second connecting rod 22 and the movable rod 23 connected to the sliding plate 32 to move upward. At the same time, the second motor 53 drives the movable rod 23 to rotate, and the automatic film attachment 20 begins.

[0059] When the sliding plate 32 moves upward to hit the first connecting rod 21, the first ventilation pipe 212 in the first connecting rod 21 stops sucking air, the top end of the film 20 is loosened by the first connecting rod 21, and the first connecting rod 21 is pushed up by the sliding plate 32 to make way, and the second connecting rod 22 and the movable rod 23 continue to move upward until the advertising film is completely covered.

[0060] After the advertising film is pasted, the sliding plate 32 moves down and resets, the third ventilation pipe 232 in the movable rod 23 stops suctioning, or switches to blowing, the first connecting rod 21 starts suctioning again, and the sliding plate 32 drives the second connecting rod 22 and the movable rod 23 to move downward to unfold the isolation film again until the sliding plate 32 is reset, the robotic arm 9 moves the bracket 1 to the isolation film recovery position, the first connecting rod 21 stops suctioning, and the isolation film falls into the isolation film recovery position, completing an automatic film pasting 20 cycle.
