Description

Technical Field

[0001] The utility model relates to the technical field of automobile part production, in particular to a film laminating machine. Background Art

[0002] With the increase in the number of automobiles and the improvement of people's living standards, the driving safety of automobiles has received more and more attention. The SBR sensor (Safety Belt Reminder, that is, the sensor of the seat belt reminder device, also called the seat occupancy sensor, abbreviated as SBR) is a thin-film type contact sensor. The contacts of the SBR sensor are evenly distributed on the force-bearing surface of the seat. When there is someone sitting on the seat, the sensor receives the external pressure and generates a trigger signal; when the controller receives the trigger signal and detects that the person on the seat is not wearing a seat belt, the controller can issue an alarm to remind the passenger to fasten the seat belt. In the production and manufacturing of SBR sensors, the lamination of the upper and lower films of the pressure film is a very critical process. The traditional lamination process relies on manual alignment or setting of the laminating machine. A laminating machine is a machine that heats two or more layers of the same or different materials, such as various plastic films, to a molten or semi-molten state and then bonds them together, or uses an adhesive to laminate two films into one. The traditional laminating machine can only perform repetitive operations and cannot make position adjustments according to different and different upper and lower films, and cannot meet the requirements of precise lamination.

[0003] Patent CN210944204U discloses a film attaching device, and specifically discloses that the first vacuum suction plate and the second vacuum suction plate directly attach the film comprehensively and then roll-press it by using the attaching roller assembly during film attachment. Bubbles may be generated during this process, resulting in poor film attachment effect. Therefore, a film laminating machine is needed that can ensure precise positioning of the upper and lower films and good lamination effect of the upper and lower films. Summary of the Utility Model

Detailed implementation manners

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0027] The purpose of the present invention is to provide a film laminating machine to solve the problems existing in the prior art, which can ensure accurate positioning of the upper and lower films and good laminating effect of the upper and lower films.

[0028] To make the above objects, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the drawings and specific implementation manners.

[0029] Such as Figures 1 - 3As shown in the figure, the utility model provides a film laminating machine, which includes a first adsorption platform 1, a second adsorption platform, and a position acquisition component 5. The first adsorption platform 1 is used to adsorb the first layer of film 101. The second adsorption platform is arranged opposite to the first adsorption platform 1. The second adsorption platform includes a sliding platform 2, a deviation rectifying platform 3, and a tiltable platform 4. The tiltable platform 4 is used to adsorb the second layer of film 102. The sliding platform 2 is slidably connected to the deviation rectifying platform 3 through a plurality of deviation rectifying mechanisms 31. The deviation rectifying mechanisms 31 can adjust the alignment of the deviation rectifying platform 3 with the first adsorption platform 1. The deviation rectifying platform 3 is fixedly connected to the tiltable platform 4 through a tilting mechanism. The tilting mechanism is used to tilt the tiltable platform 4. The sliding platform 2 can drive the deviation rectifying platform 3 and the tiltable platform 4 to slide relative to the first adsorption platform 1. The position acquisition component 5 is used to acquire the positions of the first layer of film 101 and the second layer of film 102, and is commonly connected to the processing system through an electrical signal with the deviation rectifying mechanisms 31. The tilting mechanism tilts the tiltable platform 4, with one end high and the other end low. The high end jacks up the second layer of film 102 to contact the first layer of film 101 on the first adsorption platform 1. When the sliding platform 2 slides (from the direction of the high end to the direction of the low end, from the right end to the left end in the figure), the high end gradually moves, so that the second layer of film 102 gradually adheres to the first layer of film 101, gradually reducing the generation of bubbles during pasting and improving the film pasting effect. The deviation rectifying mechanisms 31 and the position acquisition component 5 are commonly electrically connected to the processing system. The position acquisition component 5 acquires the positions of the first layer of film 101 and the second layer of film 102 and feeds them back to the processing system. After processing, the processing system gives a signal to the deviation rectifying mechanisms 31, and the deviation rectifying mechanisms 31 make adjustments to adjust the position of the deviation rectifying platform 3 and thus adjust the position of the tiltable platform 4, so that the contact points of the second layer of film 102 and the first layer of film 101 correspond one by one, providing more accurate film pasting and ensuring the composite effect of the two layers of film.

[0030] In some embodiments, the first adsorption platform 1 is a flipping platform. The flipping platform includes a first plate body, a second plate body, and multiple vertical plates. The first plate body and the second plate body are arranged in parallel. The multiple vertical plates are arranged between the first plate body and the second plate body. Square through holes and circular through holes are provided on the multiple vertical plates. The square through holes are used for air to flow through, and the circular through holes are used for the rotating shaft of the driving device to pass through. The rotating shaft of the driving device drives the flipping platform to flip. The first plate body is the first working position, and the second plate body is the second working position. The first working position and the second working position are respectively arranged on the opposite surfaces of the flipping platform. The square through holes on the vertical plates are connected to the air extraction ports of the vacuum pumps. The first working position and the second working position are both communicated with the flowing air, so that the surface pressure of the first layer of film 101 adsorbed on the first working position and the second working position is greater than the pressure on the other side, that is, both the first working position and the second working position are negative pressure working positions, and the first working position and the second working position can be used alternately.

[0031] In some embodiments, the tilting mechanism includes a plurality of telescopic frames 41. Two ends of the telescopic frame 41 are respectively fixedly connected to the edges of the rectifying platform 3 and the tiltable platform 4. The second adsorption platform further includes a support shaft 7. The support shaft 7 is arranged between the rectifying platform 3 and the tiltable platform 4 through a shaft support frame 71, and can support the tiltable platform 4. When the telescopic frame 41 drives the tiltable platform 4 to tilt, the support shaft 7 abuts against the tiltable platform 4. As a feasible implementation manner, both the first adsorption platform 1 and the second adsorption platform are rectangular structures. Four telescopic frames 41 are arranged at the four corners under the tiltable platform 4 respectively. The two telescopic frames 41 at one short side of the rectangle are raised, and the two telescopic frames 41 at the other short side are lowered, so that the support shaft 7 abuts against the middle position of the tiltable platform 4, improving the support effect. It should be noted that other types of tilting mechanisms or support brackets can also be used. For example, two telescopic frames 41 are arranged at one short side of the rectangle, and the tilting mechanism at the other short side is rotatably connected to the tiltable platform 4. The shaft support frame 71 is arranged as a lifting frame. When the telescopic frame 41 is raised, the support shaft 7 can support the tiltable platform 4 by adjusting the lifting frame.

[0032] In some embodiments, the second adsorption platform further includes a pressing roller 6 and a pressing roller support 61. One end of the pressing roller support 61 is fixedly connected to the rectifying platform 3, and is located at the edge of the tiltable platform 4 parallel to the support shaft 7 and close to the first adsorption platform 1. The other end is rotatably connected to the pressing roller 6. Among them, the pressing roller support 61 is a telescopic support. The pressing roller support 61 can be raised to make the pressing roller 6 abut against the second layer of film 102 located above the pressing roller, and the second layer of film 102 is roller-pressed to have a good laminating effect with the first layer of film 101. It should be noted that the pressing roller is preferably a pressing roller made of an elastic material. On the one hand, it can protect the second layer of film from damage. On the other hand, the elastic pressing roller can provide a relatively uniform pressure distribution during the pressing process. Compared with the traditional rigid pressing roller, it can better adapt to the surface shape change of the second layer of film, ensure the pressure in the entire pressing area is consistent, can perform pressing with higher precision, and can effectively improve the quality and performance stability of the product.

[0033] In some embodiments, any rectifying mechanism 31 includes a first slide rail 311 and a second slide rail 312 arranged vertically, and the rectifying mechanism 31 is connected with a driving device. The first slide rail 311 is slidably connected to the second slide rail 312, and the first slide rail 311 is fixedly arranged on the sliding platform 2. The rectifying platform 3 is slidably connected to the second slide rail 312. The mutually perpendicular first slide rail 311 and second slide rail 312 enable the rectifying platform 3 to slide within a square frame surrounded by the first slide rail 311 and the second slide rail 312 as sides. The rectifying mechanisms 31 are preferably four and are arranged at the four corners under the rectifying platform 3. Through the four groups of rectifying mechanisms 31, the rectifying platform 3 can be moved in the horizontal plane to align the second layer of film 102 with the first layer of film 101.

[0034] In some embodiments, there are two first slide rails 311 arranged in parallel with each other, fixedly arranged on the sliding platform 2, and used for slidably connecting the second slide rail 312. The arrangement of the two parallel first slide rails 311 makes the sliding support of the second slide rail 312 more stable. First sliders 314 and second sliders 315 are respectively arranged at both ends of the bottom surface of the second slide rail 312, and the first sliders 314 and the second sliders 315 are respectively slidably arranged in the two first slide rails 311; a third slider 316 is fixedly connected to the bottom surface of the alignment platform 3, and the third slider 316 is slidably arranged in the second slide rail 312. The first sliders 314, the second sliders 315 and the third slider 316 can be electric sliders. It should be noted that the number of the first slide rails 311 and the second slide rail 312 can also be other numbers, but there need to be multiple first slide rails 311 arranged in parallel and multiple second slide rails 312 arranged in parallel.

[0035] In some embodiments, the position acquisition assembly 5 includes a plurality of CCD cameras, and is located above the first adsorption platform 1. It is required to be able to photograph the first layer of film and the second layer of film. It can be set to four CCD cameras to ensure that the specific positions of the first layer of film 101 and the second layer of film 102 can be photographed and acquired. The accuracy of the photographing affects the alignment degree of the first layer of film 101 and the second layer of film 102, so more CCD cameras can be used.

[0036] In some embodiments, the sliding platform 2 is connected with a lead screw. The lead screw is arranged along the length direction of the first adsorption platform 1, and the lead screw is connected with a driving device. The driving device can drive the sliding platform 2 to slide along the length direction of the first adsorption platform 1 through the lead screw.

[0037] Specifically, the working process of the film laminating machine is as follows:

[0038] Place the first layer of film 101 on the first station of the flipping platform. At this time, the first station faces upward and can be captured by the CCD camera. At this time, the second adsorption platform is located on the left side of the first adsorption platform 1. Place the second layer of film 102 on the tiltable platform 4. The CCD camera takes pictures of the positions of the first layer of film 101 and the second layer of film 102 and feeds them back to the processing mechanism. After the processing mechanism processes, it gives an adjustment signal to the deviation correction mechanism 31. The driving device of the deviation correction mechanism 31 drives the slider to adjust, so as to drive the deviation correction platform 3 and the tiltable platform 4 to move, so that the second layer of film 102 on the tiltable platform 4 corresponds one by one to the contact points of the first layer of film 101. The driving device of the flipping platform drives the flipping platform to flip, so that the first layer of film 101 faces downward. Start the driving device of the second adsorption platform. The driving device drives the second adsorption platform to move to directly below the flipping platform under the transmission of the lead screw, close to the first adsorption platform 1. The two telescopic frames 41 away from the first adsorption platform 1 rise until the second layer of film 102 can contact the first layer of film 101, and at the same time, the two telescopic frames 41 close to the first adsorption platform 1 descend until the support shaft 7 can support the tiltable platform 4. Adjust the pressing roller bracket 61 on the right side of the tiltable platform 4 so that the pressing roller 6 fits and abuts against the lower part of the second layer of film 102. Then start the driving device of the second adsorption platform, so that the second adsorption platform moves to the left and returns to the left side of the flipping platform. During the return process, the second layer of film 102 moves relative to the second adsorption platform, and the pressing roller 6 gradually presses the second layer of film 102 so that the second layer of film 102 adheres to the first layer of film 101.

[0039] In the present utility model, specific examples are used to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model; at the same time, for those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation manner and application scope. To sum up, the content of this specification should not be construed as a limitation to the present utility model.
