As shown in figures 1-8, the invention provides a device for weakening skin sticker of automobile instrument panel, which comprises a frame 10, a positioning plate 20, a sticker 38 mechanism 30 and an electric cabinet 40. The frame 10 has a table 11 thereon.

The positioning plate 20 is disposed on the table 11. The top of the positioning plate 20 is provided with a positioning groove 21 extending downwards, the positioning groove 21 is used for placing the automobile instrument panel 50, and the shape of the positioning groove 21 is adapted to the shape of the automobile instrument panel 50.

The sticker 38 mechanism 30 includes a guide rail 31, a lift base 32, a first cylinder 33, a rotating plate 34, and a power source 35. The guide rail 31 is fixedly provided on the top of the table 11 in the longitudinal direction. The lifting base 32 is disposed on the guide rail 31 and slidably connected to the guide rail 31. The first cylinder 33 is longitudinally installed on the workbench 11, one end of the first cylinder 33 is connected to the workbench 11, the other end is connected to the lifting seat 32, and the first cylinder 33 is used for driving the lifting seat 32 to slide on the guide rail 31.

The rotating plate 34 is transversely disposed above the worktable 11, and both ends of the rotating plate are rotatably connected with the lifting base 32. The rotating plate 34 has a first surface 341 and a second surface 342 opposite to each other, and in an initial state, the first surface 341 and the second surface 342 are both parallel to the dashboard 50. A plurality of fixing blocks 36 are mounted on the first surface 341 and the second surface 342, and a placement groove 37 is formed in the fixing block 36 in a direction perpendicular to the rotating plate 34. The placement groove 37 is used for placing the sticker 38, and the shape of the placement groove 37 is adapted to the shape of the sticker 38. Preferably, the weakening line is H-shaped, and the corresponding plurality of fastening blocks 36 and placement grooves 37 are also H-shaped, and the weakening line and the cutting line of the H-shape make the airbag more likely to break the dashboard 50 and the weakened skin pop-up.

The sticker 38 is adsorbed in the placement groove 37 by vacuum adsorption. Vacuum suction is common knowledge in the field of decals and the specific structure will not be described in detail herein. The power source 35 is disposed on the elevating base 32 for driving the rotation of the rotating plate 34, and preferably, the power source 35 may be a servo motor 83 or a high-precision rotating cylinder.

The electric cabinet 40 is installed on the frame 10, and the electric cabinet 40 is electrically connected with the first cylinder 33 and the power source 35, respectively.

The working process of the paper pasting mechanism 30 is as follows: first, one sticker 38 is placed in each of the placement grooves 37 on the first surface 341 of the rotating plate 34, and the sticker 38 is attached to the placement groove 37 corresponding to the first surface 341 by vacuum suction. The power source 35 drives the rotating plate 34 to rotate 180 °, one sticker 38 is placed in each of the placement grooves 37 on the second surface 342 of the rotating plate 34, and the sticker 38 is attached to the placement groove 37 corresponding to the second surface 342 by vacuum attachment. At this time, the first surface 341 is directed downward.

Then, the dashboard 50 is placed in the positioning groove 21, and the dashboard 50 is adsorbed in the positioning groove 21 by vacuum adsorption.

Next, the first cylinder 33 is operated to attach the sticker 38 in the receiving groove 85 of the first surface 341 to the instrument panel 50. The instrument panel 50 is removed and a new instrument panel 50 is placed in the positioning groove 21. The power source 35 further drives the rotating plate 34 to rotate 180 °, and at this time, the second surface 342 faces downward, the first air cylinder 33 operates to paste the stickers 38 in the accommodating grooves 85 of the second surface 342 onto the new dashboard 50, and at the same time, one sticker 38 is placed again in the placing groove 37 of the first surface 341 of the rotating plate 34, and the sticker application process is completed by repeating this step.

Because the pattern formed by pasting the sticker 38 on the weakened skin of the dashboard 50 completely coincides with the weakened line, the sticker 38 provides a positioning reference for the wrapping process, and when the weakened skin of the dashboard 50 is cut, only the sticker 38 needs to be cut according to the track of the sticker 38, so that the wrapping process has a better positioning effect on the weakened line. The presence of the decal 38 provides a higher overlap of the trajectory of the cutting line with the weakening line on the panel, so that the airbag, when it is blown up, can break the weakening line on the panel 50 of the vehicle and the cutting line on the weakening skin can be ejected smoothly.

The alternate rotation of the rotating plate 34, on the one hand, facilitates the placement of the sticker 38 by the staff, since the staff places the sticker 38 each time in the upwardly directed placement slot 37 of the rotating plate 34; on the other hand, the efficiency of the paper sticking operation can be improved.

In one embodiment, three positioning posts 22 are mounted at the bottom of the positioning slot 21, and the three positioning posts 22 are adapted to three mounting holes on the dashboard 50 of the automobile. The hole positioning and the contour positioning of the positioning groove 21 can improve the positioning precision of the automobile instrument panel 50, and further improve the precision of the paper pasting operation.

In one embodiment, the rotating plate 34 is rotatably connected to the lifting base 32 through a rotating shaft 60, a limiting sleeve 61 is sleeved on one end of the rotating shaft 60, and a limiting portion 62 extending outward is formed on the outer circumferential surface of the limiting sleeve 61. Two limiting rods 63 are mounted on the lifting seat 32, and the two limiting rods 63 are respectively positioned above and below the limiting sleeve 61.

The two limiting rods 63 are matched with the driving source, and when the rotating plate rotates by 180 degrees, at least one limiting rod 63 is in contact with the limiting part 62, so that the rotating precision of the rotating plate can be improved. When a stopper rod 63 contacts the stopper portion 62 of the stopper sleeve 61, the sticker 38 in the placement groove 37 is kept parallel to the instrument panel 50.

In one embodiment, a detection plate 70 is fixedly disposed on the table 11. The detection plate 70 is positioned above the lifting seat 32, a plurality of detectors 71 are mounted at the bottom of the detection plate 70, the detectors 71 are used for detecting whether the labels in the placing grooves 37 deviate or not, and the detectors 71 are all electrically connected with the electric cabinet 40.

The detector 71 is preferably a color scale sensor and the color of the mounting block 36 should also be different from the color of the sticker 38. The color scale sensor can detect the color difference of the joint between the fixed block 36 and the sticker 38, when the color difference is detected, the sticker 38 is placed in place, and when the color difference is not detected, the sticker 38 is not placed in place. The multiple color patch sensors work simultaneously, and can detect whether the sticker 38 is placed in place with higher accuracy.

In one embodiment, the board feeding mechanism 80 is further included for transferring the dashboard 50, and the board feeding mechanism 80 is used for continuously feeding the dashboard 50 into the positioning groove 21. Specifically, the plate feeding mechanism 80 includes a first rotating shaft 81, a second rotating shaft 82, a motor 83, and two feeding plates 84.

The first rotation shaft 81 is provided on the table 11, and a second gear 811 is attached to the first rotation shaft 81 rotatably connected to the table 11. The second rotary shaft 82 is provided on the table 11 and is rotatably connected to the table 11, and a second gear 821 meshed with the second gear 811 is attached to the second rotary shaft 82. A motor 83 is installed on the table 11, and the motor 83 is used to drive the first rotating shaft 81 or the second rotating shaft 82 to rotate.

Two feed plates 84 are mounted on top of the first and second

rotating shafts

81 and 82, respectively, in the lateral direction. When the motor 83 is operated, the two feed plates 84 rotate in opposite directions due to the meshing action of the second gear 811 and the second gear 821.

The feeding plate 84 is provided with a through hole 86 which penetrates through the feeding plate in the longitudinal direction, the shape of the through hole 86 is matched with that of the automobile instrument panel 50, the top of the feeding plate 84 is provided with a plurality of accommodating grooves 85 which extend downwards, and a supporting component 90 is arranged in each accommodating groove 85.

The support assembly 90 includes a guide bar 91, a moving plate 92, a spring 93, a first electromagnet 94, and a second electromagnet 95. The guide bar 91 is arranged in the accommodating groove 85, two ends of the guide bar are fixedly connected with the groove wall of the accommodating groove 85, and the moving block is arranged in the accommodating groove 85 and is connected with the guide bar 91 in a sliding manner. The bottom of the moving block on the side close to the through hole 86 is formed with a support part 921, and the support part 921 can penetrate into the through hole 86 along the groove wall of the accommodating groove 85 to support the dashboard 50.

The spring 93 is sleeved on the guide rod 91, one end of the spring 93 is connected with the moving plate 92, the other end of the spring 93 is connected with the groove wall of the accommodating groove 85, and the moving block has a tendency to be close to the through hole 86 due to the spring 93. The first electromagnet 94 is installed on one side of the moving plate 92 far away from the through hole 86, and the second electromagnet 95 is installed on the groove wall of the accommodating groove 85 and is opposite to the first electromagnet 94. The first electromagnet 94 and the second electromagnet 95 are both electrically connected to the control box.

The instrument panel 50 can be inserted into the through hole 86 of the feeding plate 84 by the support part 921. When the first electromagnet 94 and the second electromagnet 95 are energized to attract each other, a pulling force is generated on the moving plate 92, and the supporting portion 921 of the moving plate 92 is pulled into the accommodating groove 85, so that the dashboard 50 falls off from the feeding plate 84 under the action of gravity.

For convenience of description, the two feed plates 84 are divided into a first feed plate and a second feed plate.

The working process of the plate feeding mechanism 80 is as follows: the worker puts the dashboard 50 into the through hole 86 of the first feeding plate, and then the motor 83 works, and due to the meshing action of the second gear 811 and the second gear 821, the first feeding plate rotates towards the direction close to the paper sticking mechanism 30, and the second feeding plate rotates towards the direction far away from the paper sticking mechanism 30. When the through hole 86 of the first feeding plate is aligned with the positioning groove 21, the motor 83 stops working, and at this time, the worker puts another automobile instrument panel 50 into the through hole 86 of the second feeding plate.

Then, the first electromagnet 94 and the second electromagnet 95 are energized, and the instrument panel 50 is dropped into the positioning groove 21. The motor 83 rotates a certain angle to make the first feeding plate leave the positioning groove 21, and the sticker 38 structure works. Then, the worker takes out the dashboard 50 in the positioning groove 21, the motor 83 continues to rotate, and when the through hole 86 on the second feeding plate is aligned with the positioning groove 21, the worker puts another dashboard 50 into the through hole 86 of the first feeding plate, and the process is repeated.

The motor 83 is preferably a motor 83 with a power-off self-locking function, that is, when the motor 83 is powered off, the output shaft of the motor 83 will not rotate under the action of external force. Thus, when the motor 83 operates, the first feeding plate and the second feeding plate can be kept stable.

The plate feeding mechanism 80 improves the plate feeding efficiency on one hand; on the other hand, the through hole 86 is adapted to the dashboard 50 in shape, so that the positioning function can be achieved, and the dashboard 50 falling from the feeding plate 84 can directly fall into the positioning groove 21 to complete placement and positioning. When the dashboard 50 is manually placed into the positioning groove 21, the positioning operation needs to be repeated, so that the board feeding mechanism 80 has a faster board feeding speed and a higher positioning accuracy.

In one embodiment, a second cylinder 12 is fixedly disposed on the table 11. One end of the second cylinder 12 is connected with a plate body 13 at the lower part of the frame 10, and the other end of the second cylinder penetrates through the workbench 11 and then is connected with the bottom of the positioning plate 20.

The second cylinder 12 is used to drive the positioning plate 20 to move longitudinally so that the top of the positioning plate 20 is flush with the bottom of the two feeding plates 84, respectively. Therefore, a gap between the positioning plate 20 and the bottoms of the two feeding plates 84 can be avoided, and the automobile instrument panel 50 can fall into the positioning groove 21 more smoothly after the first electromagnet 94 and the second electromagnet 95 are electrified.

In one embodiment, a cover plate 96 is mounted on the top of each receiving slot 85, and a plurality of small vent holes 97 are formed in the feeding plate 84 and communicate with the receiving slots 85. When the first electromagnet 94 and the second electromagnet 95 are de-energized, the moving plate 92 will move rapidly toward the through hole 86 under the restoring force of the spring 93.

However, due to the design of the cover plate 96 and the small ventilation holes 97, when the moving plate 92 moves rapidly towards the direction close to the through hole 86, air in the accommodating groove 85 is expelled from the small ventilation holes 97, according to the principle of small hole throttling, the moving plate 92 is subjected to a reaction force due to the pressure difference, so that the moving plate 92 is slowed down, the moving plate 92 is prevented from being directly mounted on the wall of the accommodating groove 85, noise generated by the plate feeding mechanism 80 is reduced, and the principle of the plate feeding mechanism is similar to that of a pinhole.
