Description

Technical Field

[0001] This invention relates to the field of coating equipment technology, and specifically to a coating equipment for automotive interior parts. Background Technology

[0002] The manufacturing of automotive interior parts involves machining ABS blocks into various interior parts using CNC machining after the digital model design is completed. Since the surface of these interior parts does not meet the design requirements, they cannot be used directly as interior parts for prototype vehicles. Leather covering provides a better appearance by covering the surface of ABS interior parts with leather of different textures and colors.

[0003] Currently, the most commonly used wrapping equipment for automotive interior parts is the vacuum laminating machine. This machine vacuums the product, the film, and the printed material, then sets them at a specific temperature to complete the lamination. However, existing vacuum laminating machines require manual lifting of the film and placement of the product during the lamination process, making automatic loading and unloading impossible. This not only results in high labor intensity but also increases the risk of burns to workers. Furthermore, existing vacuum laminating machines require removing a product from the machine before wrapping the next, hindering rapid re-wrapping. The long loading and unloading time also causes a significant drop in the heating element temperature, requiring a considerable amount of time for the heating elements inside the heating element to reach the required temperature before the next wrap, leading to low lamination efficiency. Summary of the Invention

[0004] The purpose of this invention is to solve the problems of inability to automatically load and unload materials and low wrapping efficiency. This invention provides an automotive interior parts wrapping device.

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

[0006] An automotive interior parts covering equipment includes: a frame, a heating cover rotatably mounted on the top of the frame, a vacuum adsorption platform that can automatically rotate inside the frame, a support on the side of the frame away from the heating cover, and a feeding conveyor line on the top of the support.

[0007] The vacuum adsorption platform has a film-coating platform at both its top and bottom. The vacuum adsorption platform has a feeding cavity inside, and the film-coating platform has a feeding port that communicates with the feeding cavity. A film is placed on the outside of the feeding port. A guide roller is rotatably installed inside the feeding cavity. The guide rollers are arranged in a linear row. A guide conveyor belt is sleeved on the outside of the guide rollers. There are baffle blocks at both ends of the feeding cavity. The two sets of baffle blocks are located above and below the guide conveyor belt, respectively. The side of the baffle block closest to the guide conveyor belt is designed to be inclined.

[0008] The feed inlet is equipped with a bottom sealing component, which can seal and block the feed inlet.

[0009] Furthermore, a tilting shaft is fixedly connected to the outer side of the vacuum adsorption platform. The tilting shaft is rotatably installed on the inner wall of the frame and is driven by a tilting motor. Both ends of the vacuum adsorption platform are designed with arcs, the center of the arcs coincides with the axis of the tilting shaft, and the edge of the material conveyor belt is tangent to the arcs.

[0010] Furthermore, the multiple sets of guide rollers are distributed in an oblique line.

[0011] Furthermore, the bottom sealing assembly includes a bottom roll groove opened inside the feed port, and a guide slide plate that can slide back and forth is provided inside the bottom roll groove. A roller is rotatably installed on the outside of the vacuum adsorption platform, and a bottom roll is wound on the outside of the roller. The bottom roll passes through the bottom roll groove and is fixedly connected to the guide slide plate. A torsion spring is provided inside the roller.

[0012] Furthermore, a rotating shaft is rotatably mounted on the side of the vacuum adsorption platform away from the roller. A threaded groove is formed on the outer side of the rotating shaft, and a nut block is threadedly connected to the outer side of the threaded groove. A telescopic cylinder is installed on the side of the vacuum adsorption platform away from the roller, and the telescopic end of the telescopic cylinder is fixedly connected to the nut block. Both ends of the rotating shaft are fixedly connected to rope wheels, and a rope is wound on the outer side of the rope wheels. A rope hole is formed at the end of the bottom winding groove away from the roller, and the rope passes through the rope hole and is fixedly connected to the guide slide plate.

[0013] Furthermore, the bottom roll is made of rubber.

[0014] Furthermore, a sealing groove communicating with the bottom roll groove is provided on the outer side of the feeding port. A sealing clamp plate is slidably connected inside the sealing groove. The sealing clamp plate has an annular design. An air cylinder is provided on the outer side of the feeding port. A piston rod is slidably connected inside the air cylinder. The piston rod is fixedly connected to the sealing clamp plate.

[0015] Furthermore, the air cylinder has a suction hole at one end near the sealing groove, and the other end of the suction hole is located between the film and the bottom roll. A negative pressure pipe is provided on the outside of the air cylinder, and the negative pressure pipe is connected to an external negative pressure device. The negative pressure pipe is connected to the middle part of the suction hole.

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. This invention features a feeding cavity within a vacuum adsorption platform. A feeding conveyor line transports automotive interior panels into the feeding cavity. A bottom sealing assembly then controls the panel to fall through the bottom feeding port onto the bottom film. The bottom sealing assembly then closes the bottom feeding port, completing the automatic feeding of the automotive interior panels. The vacuum adsorption platform is then rotated to the top for wrapping. After wrapping, the platform is rotated again, and simultaneously, the bottom sealing assembly opens the feeding port, allowing the film-coated product to fall onto the guide conveyor belt. Once the vacuum adsorption platform has rotated again, the film-coated product falls into the feeding cavity, thus completing the automatic feeding process without manual intervention.

[0018] 2. This invention, by setting up film-coating platforms at both the top and bottom of a vacuum adsorption platform, allows the loading conveyor line to transport the automotive interior panel to the loading cavity when the product on the top film-coating platform is being wrapped. Then, the bottom sealing assembly is controlled to allow the automotive interior panel to fall onto the bottom film through the bottom loading port. The bottom sealing assembly is then controlled to close the bottom loading port. This allows the next product to be loaded while the previous product is being wrapped. Once the previous product is wrapped, the vacuum adsorption platform is flipped to directly wrap the next product. Loading and wrapping are performed simultaneously, resulting in high wrapping efficiency.

[0019] 3. This invention allows for the simultaneous loading of the next product while the previous product is being wrapped. Once the previous product is wrapped, the vacuum adsorption platform is flipped to directly wrap the next product. This enables rapid wrapping of the next product without waiting for the equipment to cool down. This keeps the heating hood at a high temperature, saving energy consumption for wrapping and reducing wrapping costs. Furthermore, the equipment can reach the required heating temperature more quickly, further improving the heating temperature. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0029] A preferred embodiment of the present invention, an automotive interior trim covering device, will be described in detail below. For example... Figures 1-7 As shown, an automotive interior parts covering equipment includes: a frame 1, a heating cover 2 rotatably mounted on the top of the frame 1, a vacuum adsorption platform 3 that can automatically flip inside the frame 1, a support 4 on the side of the frame 1 away from the heating cover 2, and a feeding conveyor line 5 on the top of the support 4.

[0030] The vacuum adsorption platform 3 has a film-coating platform at both its top and bottom. The vacuum adsorption platform 3 has a feeding cavity 34 inside. The film-coating platform has a feeding port 32 that communicates with the feeding cavity 34 inside. A film 33 is provided on the outside of the feeding port 32. A guide roller 35 is rotatably installed inside the feeding cavity 34. The guide rollers 35 are arranged in a linear row. A guide conveyor belt 36 is sleeved on the outside of the guide rollers 35. Both ends of the feeding cavity 34 are provided with baffle blocks 37. The two sets of baffle blocks 37 are located above and below the guide conveyor belt 36, respectively. The side of the baffle block 37 closest to the guide conveyor belt 36 is designed to be inclined.

[0031] The feed port 32 is equipped with a bottom sealing component, which can seal and block the feed port 32.

[0032] In use, the products are placed sequentially on the feeding conveyor line 5, which then transports them to the guide conveyor belt 36. The guide conveyor belt 36 transports the products to the feeding cavity 34. An external drive source then controls the vacuum adsorption platform 3 to flip, causing the products to fall to the bottom of the feeding cavity 34. The feeding conveyor line 5 then transports another set of products to the guide conveyor belt 36, which in turn transports another set of products to the feeding cavity 34. Finally, the bottom sealing assembly opens, causing the bottom feeding port 32 to open, allowing the products to fall onto the film 33. During the flipping process, the products are held against the stop block 37, preventing them from falling. After the product is stable and flipped, it slides along the inclined surface of the baffle block 37 towards the center of the feed port 32, resulting in good feeding effect. Then, the bottom sealing component is controlled to close, which closes the feed port 32. An external negative pressure device is used to create a vacuum between the film 33 and the feed port 32, completing the automatic feeding of the product. After feeding is completed, the vacuum adsorption platform 3 is flipped by an external drive source, and another set of products falls to the bottom of the feed cavity 34. The products that have completed feeding rotate to the top, and then the heating cover 2 is placed on the products for heating and wrapping. At the same time as wrapping, another set of products that have fallen to the bottom of the feed cavity 34 completes vacuum clamping and feeding. Heating and wrapping are carried out simultaneously, resulting in high wrapping efficiency.

[0033] After the coating is completed, the bottom sealing component at the top is opened, which opens the top feeding port 32. The coated product falls onto the guide conveyor belt 36. Since the product slides along the inclined surface of the baffle block 37 towards the middle of the feeding port 32 during feeding, the coated product will fall in the middle position of the guide conveyor belt 36. Therefore, the coated product is located on the side of the feeding product near the outlet of the feeding cavity 34. When the vacuum adsorption platform 3 flips again, both the coated product and the feeding product fall to the bottom of the feeding cavity 34. When the product slides along the inclined surface of the baffle block 37 towards the middle of the feeding port 32, the product pushes the coated product to slide towards the port of the feeding cavity 34, completing the automatic unloading and making it easy to remove the coated product.

[0034] Specifically, a rotating shaft 31 is fixedly connected to the outer side of the vacuum adsorption platform 3. The rotating shaft 31 is rotatably installed on the inner wall of the frame 1. The rotating shaft 31 is driven by a rotating motor. Both ends of the vacuum adsorption platform 3 are designed with arcs. The center of the arc coincides with the axis of the rotating shaft 31. The edge of the guide conveyor belt 36 is tangent to the arc.

[0035] This design enables the flip motor to be powered on, which drives the flip shaft 31 to rotate. The flip shaft 31 then drives the vacuum adsorption platform 3 to flip. Simultaneously, since the edge of the guide conveyor belt 36 is tangent to the arc, when the vacuum adsorption platform 3 flips, both ends of the guide conveyor belt 36 will be tightly attached to the feeding conveyor line 5, ensuring stable feeding.

[0036] Specifically, multiple sets of guide rollers 35 are arranged diagonally. With this design, when the feeding conveyor line 5 transports the product to the guide conveyor belt 36, the product automatically slides to the position of the stop block 37 under the action of gravity, thereby ensuring that the product will stick tightly to the stop block 37 when it is being fed. When it is being unloaded, the wrapped product will be located on the side of the feeding product close to the outlet of the feeding cavity 34, resulting in a better unloading effect.

[0037] Specifically, the bottom sealing assembly includes a bottom roll groove 38 opened inside the feed port 32, a guide slide plate 313 that can slide back and forth is provided inside the bottom roll groove 38, a roller 310 is rotatably installed on the outside of the vacuum adsorption platform 3, a bottom roll 312 is wound on the outside of the roller 310, the bottom roll 312 passes through the bottom roll groove 38 and is fixedly connected to the guide slide plate 313, and a torsion spring 311 is provided inside the roller 310.

[0038] The guide slide plate 313 is controlled by the drive source to slide along the bottom roll groove 38. When it is necessary to close the feed port 32, the guide slide plate 313 is moved away from the roll 310. The guide slide plate 313 drives the bottom roll 312 to unfold, and the bottom roll 312 closes the feed port 32. When it is necessary to open the feed port 32, the guide slide plate 313 is moved closer to the roll 310. At this time, the roll 310 rotates under the action of the torsion spring 311. The roll 310 rewinds the bottom roll 312, and the bottom roll 312 closes the feed port 32.

[0039] Specifically, a rotating shaft 314 is rotatably mounted on the side of the vacuum adsorption platform 3 away from the roller 310. A threaded groove 315 is opened on the outer side of the rotating shaft 314, and a nut block 317 is threadedly connected to the outer side of the threaded groove 315. A telescopic cylinder 316 is installed on the side of the vacuum adsorption platform 3 away from the roller 310. The telescopic end of the telescopic cylinder 316 is fixedly connected to the nut block 317. Both ends of the rotating shaft 314 are fixedly connected to rope wheels 318. A rope 319 is wound on the outer side of the rope wheel 318. A rope hole 39 is opened at the end of the bottom winding groove 38 away from the roller 310. The rope 319 passes through the rope hole 39 and is fixedly connected to the guide slide plate 313.

[0040] When it is necessary to close the feed inlet 32, the telescopic cylinder 316 is activated, extending its telescopic end. This telescopic end moves the nut block 317, which in turn drives the rotating shaft 314 to rotate via the threaded groove 315. The rotating shaft 314 then drives the rope wheel 318 to rotate, causing it to wind up the rope 319. The wound rope 319 moves the guide slide plate 313 away from the winding roller 310, and the guide slide plate 313 causes the bottom roll 312 to unfold, closing the feed inlet 32. When it is necessary to open the feed inlet 32, the telescopic cylinder... The telescopic end of cylinder 316 retracts, and the telescopic end drives the nut block 317 to move. The nut block 317 drives the rotating shaft 314 to reverse through the threaded groove 315. The rotating shaft 314 drives the rope wheel 318 to reverse. The rope wheel 318 unwinds the wound rope 319. The wound rope 319 releases the guide slide plate 313. At this time, the winding roller 310 rotates under the action of the torsion spring 311. The winding roller 310 winds up the bottom roll 312. The bottom roll 312 opens the feed port 32. At the same time, under the action of the thread self-locking, it ensures that the bottom roll 312 unfolds and winds up stably and the covering is stable.

[0041] Specifically, the bottom roll 312 is made of rubber. This design allows the bottom roll 312 to adhere tightly to the product even when the equipment generates negative pressure, resulting in a tighter fit between the film and the product and a better wrapping effect.

[0042] Specifically, a sealing groove 320 communicating with the bottom roll groove 38 is provided on the outer side of the feeding port 32. A sealing clamp 321 is slidably connected inside the sealing groove 320. The sealing clamp 321 is annularly designed. An air cylinder 322 is provided on the outer side of the feeding port 32. A piston rod 323 is slidably connected inside the air cylinder 322. The piston rod 323 is fixedly connected to the sealing clamp 321.

[0043] Before the equipment generates negative pressure, the internal air pressure of the air cylinder 322 is changed. The air pressure causes the piston rod 323 to slide. The piston rod 323 drives the sealing clamp 321 to clamp around the edge of the bottom roll 312, resulting in a good sealing effect.

[0044] Specifically, the air cylinder 322 has a suction hole 324 at one end near the sealing groove 320, and the other end of the suction hole 324 is located between the film 33 and the bottom roll 312. A negative pressure pipe 325 is provided on the outside of the air cylinder 322. The negative pressure pipe 325 is connected to an external negative pressure device and is connected to the middle part of the suction hole 324.

[0045] The negative pressure pipe 325 is connected to an external negative pressure device. The external negative pressure device causes the negative pressure pipe 325 to generate negative pressure. The negative pressure pipe 325 generates negative pressure at both ends of the suction hole 324. The suction hole 324 generates negative pressure inside the air cylinder 322. The negative pressure causes the piston rod 323 to slide. The piston rod 323 drives the sealing clamp 321 to clamp around the edge of the bottom roll 312 for sealing. At the same time, the sealing generates negative pressure between the film 33 and the bottom roll 312, and the product is clamped by negative pressure.

[0046] Working principle: During use, products are placed sequentially on the feeding conveyor line 5, which then transports them to the guide conveyor belt 36. The guide conveyor belt 36 transports the products to the feeding cavity 34. Then, an external drive source controls the vacuum adsorption platform 3 to flip, causing the products to fall to the bottom of the feeding cavity 34. Next, the feeding conveyor line 5 transports another set of products to the guide conveyor belt 36, which in turn transports the other set of products to the feeding cavity 34. The telescopic cylinder 316 retracts, causing the nut block 317 to move. The nut block 317, through the threaded groove 315, carries... The rotating shaft 314 reverses, causing the rope wheel 318 to reverse as well. The rope wheel 318 unwinds the wound rope 319, which then releases the guide slide plate 313. At this time, the winding roller 310 rotates under the action of the torsion spring 311, and the winding roller 310 winds up the bottom roll 312. The bottom roll 312 opens the feed port 32, allowing the product to fall onto the film 33. During the flipping process, the product rests against the stop block 37, preventing it from falling and ensuring stable flipping. After the flipping is complete, the product slides along the inclined surface of the stop block 37 towards the center of the feed port 32, resulting in good feeding performance. The telescopic cylinder 316 is then controlled to extend its telescopic end. The telescopic end drives the nut block 317 to move. The nut block 317 drives the rotating shaft 314 to rotate through the threaded groove 315. The rotating shaft 314 drives the rope wheel 318 to rotate. The rope wheel 318 winds up the rope 319. The wound rope 319 drives the guide slide plate 313 away from the winding roller 310. The guide slide plate 313 drives the bottom roll 312 to unfold. The bottom roll 312 closes the feed port 32. The negative pressure pipe 325 is connected to the external negative pressure equipment. The external negative pressure equipment causes the negative pressure pipe 325 to generate negative pressure. The negative pressure pipe 325 generates negative pressure at both ends of the suction hole 324. The suction hole 324 generates negative pressure inside the air cylinder 322. The negative pressure causes the piston rod 323 to move. The piston rod 323 slides and drives the sealing clamp 321 to clamp around the edge of the bottom roll 312 for sealing. At the same time, the sealing creates a negative pressure between the film 33 and the bottom roll 312, and the product is clamped under negative pressure to complete the automatic feeding of the product. After the feeding is completed, the vacuum adsorption platform 3 is flipped by the external drive source, and another set of products falls to the bottom of the feeding cavity 34. The products that have been fed rotate to the top, and then the heating cover 2 is placed on the products for heating and wrapping. At the same time as the wrapping, another set of products that have fallen to the bottom of the feeding cavity 34 completes the vacuum clamping and feeding. Heating and wrapping are carried out at the same time, and the wrapping efficiency is high.

[0047] After the coating is completed, the bottom sealing component at the top is opened, which opens the top feeding port 32. The coated product falls onto the guide conveyor belt 36. Since the product slides along the inclined surface of the baffle block 37 towards the middle of the feeding port 32 during feeding, the coated product will fall in the middle position of the guide conveyor belt 36. Therefore, the coated product is located on the side of the feeding product near the outlet of the feeding cavity 34. When the vacuum adsorption platform 3 flips again, both the coated product and the feeding product fall to the bottom of the feeding cavity 34. When the product slides along the inclined surface of the baffle block 37 towards the middle of the feeding port 32, the product pushes the coated product to slide towards the port of the feeding cavity 34, completing the automatic unloading and making it easy to remove the coated product.
