Description

Technical Field

[0001] This invention relates to the field of trim panel edging, and in particular to a high-efficiency hot-pressing edging device for automotive trim panels. Background Technology

[0002] Edge banding is a processing technology that uses materials such as PVC, real wood veneer, and leather, combined with processes such as pasting, folding, injection molding, or painting, to seal the exposed edges of wood, plastic, and metal panels. Its core function is to prevent the panels from cracking and getting damp, and to improve the appearance and safety of use. The high-efficiency hot-press edge banding of automotive trim panels is a specialized application of this technology in the automotive interior field. Through an integrated process of heating and pressurizing the upper and lower molds, suction cup positioning, and automatic pre-folding, genuine leather, PU, ​​and other covering materials are precisely fitted to the interior frame. It is suitable for complex curved parts such as dashboards, door panels, and armrests. It not only solves the problems of low efficiency and poor consistency of traditional manual edge banding, but also ensures the edge banding strength and flatness through infrared heating and multi-mold temperature control technologies, achieving a dual improvement in production efficiency and interior texture.

[0003] According to CN117656447A, a high-efficiency hot-pressing edge-wrapping device for automotive trim panels and its usage method are disclosed. This technology includes: "a frame, the frame having: an upper pressing mold, the frame having a driving component for driving the upper pressing mold to move vertically, the upper pressing mold having a positioning groove for inserting interior trim parts and a suction cup for adsorbing interior trim parts; a lower pressing mold for supporting and positioning the interior trim parts, the frame having several hot pressing blocks arranged circumferentially along the lower pressing mold, the frame having a pressing cylinder for moving the hot pressing blocks closer to or away from the lower pressing mold; several pressing blocks located on one side of the lower pressing mold, all pressing blocks being located above the hot pressing blocks, the frame having a pressing cylinder for moving the pressing blocks closer to or away from the hot pressing blocks, the pressing cylinder moving when the hot pressing blocks move; a heating device fixedly connected to one side of the frame for heating the lower pressing mold, all hot pressing blocks, and all pressing blocks, etc., which has the technical effect of facilitating the hot pressing of automotive interior trim parts with multiple wrapping surfaces."

[0004] However, compared with traditional methods, the handling and placement of the covered panels requires multiple positioning points, and the space under the mold is narrow, which makes the operation time-consuming and disrupts the continuity of processing, resulting in low processing smoothness and limited production efficiency. During the handling, it is necessary to be in close contact with the working area of ​​the hot press, which makes it easy to cause safety accidents due to accidental contact with high-temperature parts or improper operation, posing obvious production safety hazards.

[0014] In a preferred embodiment, an electric push rod is fixedly connected to the surface of the support plate, and an edge-sealing pressure plate is fixedly connected to the output end of the electric push rod.

[0015] The technical effect of adopting the above-mentioned further solution is that by setting it so that the leather material covering the edge of the trim panel can be squeezed inward, thereby improving the edge binding effect.

[0016] In a preferred embodiment, a guide post is fixedly connected to the upper end of the lower pressure plate, and the surface of the guide post is slidably connected to the top plate.

[0017] The technical effect of adopting the above-mentioned further solution is that the movement of the lower pressure plate is made more stable by setting it up.

This ensures that the trim panel is lifted without deviation, avoids misalignment with the upper mold before hot pressing, ensures comprehensive hot pressing coverage and meets the required results, and improves the quality of hot pressing processing. At the same time, the curved edge design of the clamping plate can cooperate with the edge-wrapping pressure plate to avoid obstruction, and the spring steel plate drives the clamping plate to return to its original position, without hindering the hot pressing operation of the upper mold and ensuring a smooth processing flow.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example

[0037] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, this invention provides a high-efficiency hot-pressing edge-wrapping device for automotive trim panels, including a worktable 1. A push plate 2 is slidably connected to the upper end of the worktable 1. The push plate 2 can slide on the upper end of the worktable 1 to push the trim panel to the target position. A side plate 3 is fixedly connected to the side end of the push plate 2. The upper ends of the push plate 2 and the side plate 3 are respectively provided with arc edges. The arc edges guide the trim panel to be placed in a position that simultaneously fits the push plate 2 and the side plate 3, facilitating placement and alignment, and avoiding scratches during placement. A groove 4 is provided on the surface of the worktable 1. A movable plate 5 is fixedly connected to the lower end of the push plate 2. The surface of the movable plate 5 is slidably connected to the worktable 1 through the groove 4. The movable plate 5 is adapted to the groove 4. A first spring 6 is fixedly connected to the side end of the movable plate 5. A base 7 is fixedly connected inside the worktable 1. The fixed end of the first spring 6 is fixedly connected to the base 7. When the push plate 2 resets, the first spring 6 is compressed. When the trim panel is placed on the surface of the push plate 2 and the side plate 3, the first spring 6 compresses. The push allows the covering panel to be moved to a predetermined position. A hydraulic cylinder 8 is fixedly connected inside the workbench 1. A hidden groove 9 is opened on the surface of the workbench 1. A lower mold 10 is fixedly connected to the output end of the hydraulic cylinder 8. The surface of the lower mold 10 is slidably connected to the workbench 1 through the hidden groove 9. The lower mold 10 is adapted to the hidden groove 9. Before the covering panel moves above the hidden groove 9, the lower mold 10 is placed inside the workbench 1 to avoid obstructing the movement of the covering panel. After the skin material is coated with glue and pre-bonded with the substrate, it is placed on the side of the push plate 2 and the side plate 3. The pushing plate 2 transports the covering panel to the hidden groove 9, and the hydraulic cylinder 8 drives the lower mold 10 to lift and support the covering panel, thereby achieving the effect of hot pressing and wrapping. This reduces the working time of handling and placing the covering panel. Through continuous operation, the processing smoothness of the covering panel is improved, and the problem of safety accidents caused by manual handling and close contact with the hot press working area is solved, thus improving the safety of the production process.

[0038] like Figure 1 - Figure 3 As shown: A side frame 11 is fixedly connected to the upper end of the workbench 1, and a top plate 12 is fixedly connected to the upper end of the side frame 11. A second hydraulic cylinder 13 is fixedly connected to the surface of the top plate 12, so that the second hydraulic cylinder 13 can be fixed above the workbench 1. A lower pressure plate 14 is fixedly connected to the output end of the second hydraulic cylinder 13. When the second hydraulic cylinder 13 is started, the lower pressure plate 14 can be moved up and down to the target position at the lower end of the top plate 12 by pushing the output end of the second hydraulic cylinder 13.

[0039] like Figure 2 , Figure 3 and Figure 5As shown: A rope 15 is fixedly connected to the lower end of the top plate 12, and a movable pulley 16 is fixedly connected to the upper end of the lower pressure plate 14. The surface of the rope 15 is in contact with the movable pulley 16, and the rope 15 and the movable pulley 16 are compatible. When the lower pressure plate 14 descends, the rope 15 is pulled. A first fixed pulley 17 is fixedly connected to the lower end of the top plate 12, and the surface of the rope 15 is in contact with the first fixed pulley 17, and the rope 15 and the first fixed pulley 17 are compatible. The pulling direction of the rope 15 is changed by the first fixed pulley 17. A pulley frame 18 is fixedly connected to the surface of the workbench 1, and a second fixed pulley 19 is fixedly connected to the surface of the pulley frame 18. The surface of the rope 15 is in contact with the second fixed pulley 19. 9. The rope 15 is fitted to the second fixed pulley 19. The second fixed pulley 19 changes the pulling direction of the rope 15. The end of the rope 15 is fixedly connected to the push plate 2. When the pressure plate 14 moves down, the pressure plate 14 presses down the rope 15 through the movable pulley 16. The end of the rope 15 is fixedly connected to the push plate 2 through the action of the first fixed pulley 17 and the second fixed pulley 19. This makes the push plate 2 pull outward when the pressure plate 14 presses down, so as to drive the push plate 2 to reset. At the same time, the push plate 2 is prevented from obstructing the subsequent hot pressing at the lower end of the pressure plate 14. After resetting, the covering panel can continue to be placed between the push plate 2 and the side plate 3 to realize the operation of cyclic feeding.

[0040] like Figure 3 and Figure 6 As shown: A guide rod 20 is slidably connected to the surface of the lower pressure plate 14. The inner circumference of the lower pressure plate 14 is equal to the outer circumference of the rope 15. A support plate 21 is fixedly connected to the lower end of the guide rod 20. An upper mold 22 is fixedly connected to the lower end of the support plate 21. The upper mold 22 is used to perform a hot pressing operation on the covering panel. A second spring 23 is fixedly connected to the upper end of the upper mold 22. The fixed end of the second spring 23 is fixedly connected to the lower pressure plate 14. The second spring 23 buffers the hot pressing operation of the upper mold 22 to prevent overheating. The hard contact caused damage to the covering panel. The guide rod 20 has a threaded connection to a positioning ring 24. The guide rod 20 and the positioning ring 24 are adapted to each other. The lower end of the positioning ring 24 is slidably connected to the lower pressure plate 14. By rotating the positioning ring 24, the position height of the guide rod 20 and the lower pressure plate 14 can be changed, thereby changing the pressure during contact according to the thickness and material of the leather, improving the hot pressing effect of the covering panel. When the lower pressure plate 14 moves downward, it drives the upper mold 22 to perform hot pressing operation on the covering panel.

[0041] like Figure 1 As shown: An electric push rod 25 is fixedly connected to the surface of the support plate 21, so that the electric push rod 25 moves and rises with the support plate 21. The output end of the electric push rod 25 is fixedly connected to the edge-binding pressure plate 26. When the upper mold 22 presses up and stabilizes, the electric push rod 25 is started to drive the support plate 21 to perform hot pressing from the side edge of the covering panel, so that the leather material at the edge of the covering panel can be squeezed inward, thereby improving the edge-binding effect.

[0042] like Figure 1 As shown: A guide post 27 is fixedly connected to the upper end of the lower pressure plate 14. The surface of the guide post 27 is slidably connected to the top plate 12. The outer circumference of the guide post 27 is equal to the inner circumference of the top plate 12, so that the lower pressure plate 14 is limited and supported by the guide post 27 when it moves up and down, thereby making the movement of the lower pressure plate 14 more stable and the hot pressing pressure more uniform.

[0043] like Figure 7 As shown: A trapezoidal toothed plate 28 is fixedly connected to the lower end of the lower mold 10, so that when the lower mold 10 is raised or lowered, the trapezoidal toothed plate 28 moves up and down. A double-acting screw 29 is rotatably connected inside the worktable 1. The inner circumference of the worktable 1 is equal to the outer circumference of the double-acting screw 29. A gear 30 is fixedly connected to the surface of the double-acting screw 29. The surface of the gear 30 meshes with the trapezoidal toothed plate 28. The gear 30 and the trapezoidal toothed plate 28 are matched. When the trapezoidal toothed plate 28 rotates, it drives the gear 30 to rotate accordingly. A slide 31 is threadedly connected to the surface of the double-acting screw 29. The double-acting screw 29 and the slide 31 are matched. The surface of the slide 31 is slidably connected to the worktable 1. The slide 31 and the worktable 1 are matched so that when the lower mold 10 is raised, it drives the trapezoidal toothed plate 28 to move up and down, thereby driving the gear 30 to rotate. At the same time, the rotation of the gear 30 drives the trapezoidal toothed plate 28 to rotate, thereby causing the double-acting screw 29 to rotate accordingly, and thus causing the slide 31 to move inward from both sides at the same time.

[0044] like Figure 8 As shown: A positioning plate 32 is fixedly connected to the upper end of the slide table 31. A spring steel plate 33 is fixedly connected to the surface of the positioning plate 32. A clamping plate 34 is fixedly connected to the side end of the spring steel plate 33. The top edge of the clamping plate 34 is provided with an arc edge. When the covering panel moves above the lower mold 10, the clamping plate 34 is moved by the slide table 31 moving inward from both sides, so that it is fixed diagonally with the covering panel. This ensures that the position does not shift when the lower mold 10 lifts it up, avoiding misalignment between the covering panel and the upper mold 22 before hot pressing, which would result in insufficient hot pressing coverage area and failure to achieve the hot pressing effect in some areas, leading to unqualified hot pressing quality. Furthermore, the arc edge of the clamping plate 34 is used to press the clamping plate 34 to both sides when the edge pressing plate 26 follows the upper mold 22 downward, avoiding obstruction of the hot pressing operation of the upper mold 22. After the edge pressing plate 26 rises, the clamping plate 34 is reset by the push of the spring steel plate 33.

[0045] Working principle:

[0046] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, this high-efficiency hot-pressing edge-wrapping equipment for automotive trim panels, during use, places the trim panel, which has been pre-bonded with adhesive and substrate, on the sides of the push plate 2 and side plate 3. Precise alignment is achieved by guiding the curved edges of the push plate 2 and side plate 3. Simultaneously, the thrust of the first spring 6 drives the push plate 2 to slide along the slide groove 4 via the moving plate 5 until the trim panel is conveyed above the hidden groove 9. At this point, the first hydraulic cylinder 8 is activated, driving the lower mold 10 to rise along the hidden groove 9. When the hidden groove 9 rises, the trapezoidal toothed plate 28 moves up and down synchronously. Through the meshing transmission of the bidirectional screw 29 and gear 30, the slide table 31 moves inward from both sides, thereby moving the positioning plate 32, causing the spring steel plate... 33 pushes the clamping plate 34 to precisely fix the diagonal of the covered trim panel, ensuring that the trim panel does not shift after being lifted, thus improving the accuracy of hot pressing; then, the second hydraulic cylinder 13 is activated, and the output end of the second hydraulic cylinder 13 pushes the lower pressure plate 14 to descend along the sliding direction between the guide post 27 and the surface of the top plate 12, driving the upper mold 22 to hot press the covered trim panel. When the lower pressure plate 14 moves down, the lower pressure plate 14 presses down the rope 15 through the movable pulley 16, and the rope 15 is fixedly connected to the push plate 2 at its end through the action of the first fixed pulley 17 and the second fixed pulley 19. This causes the push plate 2 to be pulled outward when the lower pressure plate 14 is pressed down, thereby driving the push plate 2 to return to its original position, while avoiding the push plate 2 from obstructing the subsequent hot pressing at the lower end of the lower pressure plate 14. After pressing and resetting, the covering panel can continue to be placed between the push plate 2 and the side plate 3 to achieve cyclic feeding. At the same time, the guide column 27 ensures the stability of the lower pressure plate 14 during lifting and lowering, so as to make the hot pressing pressure uniform. The second spring 23 buffers the hot pressing of the upper mold 22 to prevent damage to the panel. The positioning ring 24 can adjust the height of the guide rod 20 according to the thickness of the leather to optimize the hot pressing effect. After the hot pressing of the upper mold 22 is stable, the electric push rod 25 is started. The electric push rod 25 drives the edge pressing plate 26 to hot press from the side edge of the panel inward, so that the leather is squeezed inward to improve the edge pressing effect. In addition, through the arc edge setting of the clamping plate 34, when the edge pressing plate 26 follows the upper mold 22 to press down, the clamping plate 34 is squeezed to the side to avoid obstructing the upper mold. The hot pressing operation of mold 22 and edge-sealing pressure plate 26 is performed. After the edge-sealing pressure plate 26 rises, the clamping plate 34, which is no longer squeezed by the edge-sealing pressure plate 26, is pushed back by the spring steel plate 33. After the hot pressing edge-sealing is completed, all components are reset. The first hydraulic cylinder 8 is started to drive the lower mold 10 to descend. At the same time as the lower mold 10 descends, the electric trapezoidal toothed plate 28 descends, causing the gear 30 to rotate in the opposite direction. This allows the slide table 31 to slide the clamping plate 34 to both sides until the lower mold 10 returns to the bottom of the hidden groove 9, avoiding affecting the secondary feeding of the push plate 2. The push plate 2 also returns to its original position and can receive the covering panel again to achieve cyclic feeding. The entire process reduces manual intervention through structural linkage, improving processing efficiency, quality and safety.

However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
