Description

Technical Field

[0001] This utility model relates to the field of coating technology, and in particular to a coating device. Background Technology

[0002] Automotive interior components refer to products used inside a car, including dashboards, door panels, seats, headliners, rear fascias, hoods, carpets, sun visors, and glove boxes. These components not only serve a decorative purpose but also meet functional and safety requirements. The production process of automotive interior components often employs a vacuum adsorption process, which involves coating the outer layer of the components with a decorative film to enhance both the aesthetics and comfort of the interior.

[0003] In existing technologies, the steps of heating, mold pressing, and vacuum establishment for automotive interior parts are often performed in stages or semi-automatically. For example, heating needs to be completed at one station first, and then the parts need to be transferred manually or by a robot to another station for lamination. This discontinuous operation mode not only increases the production cycle time, but also affects the lamination effect due to heat loss during the transfer process, and introduces quality risks due to positioning errors. Therefore, we propose a lamination equipment to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a coating device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A laminating device includes a vacuum laminating machine body. A high-temperature resistant cylinder is fixedly connected inside the vacuum laminating machine body. A pressing component is fixedly connected to the bottom of the output end of the high-temperature resistant cylinder. A pressing mold is fixedly connected to the bottom of the pressing component. An automotive interior part mold is fixedly connected inside the vacuum laminating machine body. Two top shafts are fixedly connected inside the vacuum laminating machine body. Two bearings are fixedly fitted on the outer walls of each of the two top shafts. Pulleys are fixedly fitted on the outer rings of the four bearings. Four steel wire ropes are fixedly connected to the top of the pressing component. The steel wire ropes are fitted onto the outer walls of the pulleys. The four steel wire ropes are fixedly connected to a support rod in pairs. Two columns are fixedly connected inside the vacuum laminating machine body. A heating component is provided inside the vacuum laminating machine body.

[0007] Preferably, the heating assembly includes multiple electric heating rods, and the outer walls of the two columns are slidably fitted with the same U-shaped frame. The inner wall of the U-shaped frame is fixedly connected to both ends of the two support rods. The outer wall of the U-shaped frame is fixedly inlaid with two stainless steel double-layer mesh frames. The inner walls of the two stainless steel double-layer mesh frames are respectively fixedly connected to both ends of the multiple electric heating rods. The stainless steel double-layer mesh frames are used to fix the multiple electric heating rods. Its double-layer mesh structure can effectively fix the heating rods and has good heat transmission and heat dissipation area.

[0008] Preferably, the outer wall of the vacuum laminating machine body is hinged with two sealing doors, and door locks are installed between the two sealing doors and the vacuum laminating machine body.

[0009] Preferably, a vacuum pump is fixedly connected inside the vacuum coating machine body, and an L-shaped pipe is fixedly connected to the output end of the vacuum pump. A valve is fixedly installed on the outer wall of the L-shaped pipe.

[0010] Preferably, the outer wall of the pressing component has four sliding holes, and the inner walls of the four sliding holes are slidably connected with guide rods. The two ends of the four guide rods are fixedly connected to the inner wall of the vacuum coating machine body. The four guide rods provide guidance for the movement of the pressing component and the mold, effectively preventing them from shaking or twisting during the movement.

[0011] Preferably, the bottom of the stainless steel double-layer mesh frame is in contact with the inner wall of the vacuum coating machine body.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] This solution utilizes a linkage mechanism composed of a high-temperature resistant cylinder, steel wire rope, and pulleys. This structure ensures that while the pressing part drives the die to press down for lamination, the return frame (carrying the electric heating rod) can be simultaneously lifted to remove it from the heating area. This seamless action eliminates heat loss and positioning errors caused by workpiece transfer in traditional processes, thus ensuring that the film is pressed into place in one go at the optimal plasticity temperature. This effectively avoids defects such as wrinkles and bubbles, significantly improving the yield and consistency of the lamination. By adopting a synergistic mechanism of mechanical pressing followed by vacuum adsorption, it can ensure perfect, bubble-free lamination of complex workpieces with deep cavities or sharp angles.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Depend on Figures 1-3 As shown, a coating device is disclosed, including a vacuum coating machine body 1. Two sealing doors 2 are hinged to the outer wall of the vacuum coating machine body 1. Their good sealing performance ensures that the inside of the cavity is isolated from the outside during the vacuuming process, maintaining a stable negative pressure environment. A vacuum pump 3 is fixedly connected inside the vacuum coating machine body 1. An L-shaped tube is fixedly connected to the output end of the vacuum pump 3. A valve is fixedly installed on the outer wall of the L-shaped tube. The vacuum pump 3 extracts the air in the cavity through the L-shaped tube to form a vacuum. The valve is used to exhaust the air, thereby using atmospheric pressure to tightly press the film onto the surface of the workpiece.

[0021] A high-temperature resistant cylinder 4 is fixedly connected inside the vacuum coating machine body 1. A pressing component 5 is fixedly connected to the bottom of the output end of the high-temperature resistant cylinder 4. The pressing component 5 transmits the power of the cylinder to the pressing mold 6. At the same time, the four sliding holes opened on it cooperate with the guide rods 8 to ensure the verticality and stability of the entire pressing process and prevent skewing. The outer wall of the pressing component 5 has four sliding holes, and the inner wall of each of the four sliding holes is slidably connected to the guide rods 8. The two ends of the four guide rods 8 are fixedly connected to the inner wall of the vacuum coating machine body 1. The four guide rods 8 provide guidance for the movement of the pressing component 5 and the pressing mold 6, effectively preventing them from shaking or twisting during the movement.

[0022] The bottom of the pressing part 5 is fixedly connected to the pressure mold 6, and the interior of the vacuum coating machine body 1 is fixedly connected to the automotive interior part mold 7. The surface of the automotive interior part mold 7 matches the workpiece. When pressing down, it can apply uniform mechanical pressure to the workpiece covered with film, perform pre-forming and preliminary degassing, and form a synergistic effect with the subsequent vacuum adsorption to ensure perfect coating.

[0023] The vacuum coating machine body 1 has two top shafts 9 fixedly connected inside. Two bearings are fixedly fitted on the outer walls of the two top shafts 9. Pulleys 10 are fixedly fitted on the outer rings of the four bearings. Four steel wire ropes 11 are fixedly connected to the top of the pressing component 5. The steel wire ropes 11 are fitted on the outer walls of the pulleys 10. The steel wire ropes 11 are guided by the pulleys 10 to synchronously transmit the power of the pressing mold 6 to the heating component, realizing the linkage of the two actions. The four steel wire ropes 11 are fixedly connected to the support rods 12 in pairs. The vacuum coating machine body 1 has two columns 13 fixedly connected inside. The two columns 13 ensure that the heating component maintains a horizontal and stable movement trajectory during the lifting process, avoiding interference with surrounding components.

[0024] The vacuum coating machine body 1 is equipped with a heating component, which includes multiple electric heating rods 16. The outer walls of the two columns 13 are slidably fitted with the same U-shaped frame 14. The inner wall of the U-shaped frame 14 is fixedly connected to the two ends of the two support rods 12. The outer wall of the U-shaped frame 14 is fixedly inlaid with two stainless steel double-layer mesh frames 15. The inner walls of the two stainless steel double-layer mesh frames 15 are respectively fixedly connected to the two ends of the multiple electric heating rods 16. The electric heating rods 16 serve as heat sources. The multiple electric heating rods 16 are evenly distributed, which can quickly and evenly heat the workpiece and the mold, softening the film to the optimal plastic state. The bottom of the stainless steel double-layer mesh frame 15 is in contact with the inner wall of the vacuum coating machine body 1. The stainless steel double-layer mesh frame 15 is used to fix the multiple electric heating rods 16. Its double-layer mesh structure can effectively fix the heating rods and has good heat transmission and heat dissipation area. The cables of the electric heating rods 16 are moved by existing high-temperature resistant drag chains (steel-aluminum drag chains).

[0025] Working principle: During use, the automotive interior trim piece is placed on top of the automotive interior trim piece mold 7, and then the decorative film is covered on top of the automotive interior trim piece. The sealing door 2 is closed, and multiple electric heating rods 16 operate to heat the automotive interior trim piece and the automotive interior trim piece mold 7, heating the automotive interior trim piece to a plastic state. Adhesive can be applied to the contact surface between the automotive interior trim piece and the automotive interior trim piece mold 7. The high-temperature resistant cylinder 4 operates, driving the lowering component 5 downwards. The downward movement of the lowering component 5 drives one end of each of the four steel wire ropes 11 downwards. The wire rope 11 slides along the four pulleys 10, while the other end of the four wire ropes 11 drives the two support rods 12 and the return frame 14 to move upward. After the return frame 14 moves upward, it no longer heats the car interior parts and the car interior parts mold 7. At the same time, the pressing part 5 moves downward, driving the pressing mold 6 to move downward. The pressing mold 6 presses onto the car interior parts and applies pressure. At this time, the return frame 14 is at the highest point. The vacuum pump 3 operates to form a vacuum inside the vacuum laminating machine body 1, and extracts the air from the contact surface between the car interior parts and the car interior parts mold 7.

[0026] It should be noted that when actually put into use, an existing PLC controller can be added. The PLC controller is electrically connected to the vacuum coating machine body 1, vacuum pump 3, high-temperature resistant cylinder 4, and electric heating rod 16 to facilitate the control of the overall operation.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here. Furthermore, the structure and principle of the components known to those skilled in the art can be learned by those skilled in the art through technical manuals or conventional experimental methods.
