Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of edge banding devices for sheet metal, and in particular to an edge banding device for automotive interior panels. Background Technology
[0002] Automotive interior panel edging is a process in which flexible materials such as leather or fabric are covered on the surface of the interior panel, and the excess material at the edges is folded inward and wrapped around the side of the interior panel. For regular interior panels, they are usually first fixed on a workbench, and then the edging roller (or pressure roller) moves along the edge of the panel. Through mechanical pressure, the hanging wrapping material is gradually bent and pressed tightly against the side of the interior panel to form a smooth wrapping layer, which improves the aesthetics and durability.
[0003] A Chinese utility model patent with authorization announcement number CN222080106U, entitled "An Edge-Wrapping Device for Automotive Interior Panels," was found. This device comprises a first moving block, a second moving block, an active connecting rod, a transmission connecting rod, and a driven connecting rod. When the first pneumatic cylinder operates, the second moving block begins to move to the left. The active connecting rod, driven by the second moving block, begins to rotate, causing the transmission connecting rod to rotate. Simultaneously, the rotation of the transmission connecting rod causes the driven connecting rod to rotate, causing the other end of the driven connecting rod to move the first moving block to the right. At this point, the first and second moving blocks are moving in opposite directions. Finally, as the first and second moving blocks move, the two clamping blocks clamp the interior panel.
[0004] While the aforementioned structure can adjust the clamping width to accommodate interior panels of different sizes, its edge-wrapping rollers can only move up and down to press the vertical sides of the interior panel. It cannot further bend the wrapping material and wrap it to the bottom edge of the interior panel, resulting in the bonding surface between the wrapping material and the interior panel being limited to the sides, with the bottom lacking effective wrapping. Long-term use can easily lead to edge lifting or delamination. Furthermore, after completing the edge wrapping of both sides of the interior panel, it is necessary to manually remove the interior panel, manually rotate the angle, re-clamp it, and then repeat the operation on the remaining unwrapped sides. This process is not only cumbersome, but repeated clamping can also easily cause the wrapping material to shift or the surface of the interior panel to be damaged. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the present invention provides an automotive interior panel edge-wrapping device, which solves the problems of cumbersome edge-wrapping operation and limited pressing angle in the existing technology, which affect the bonding effect between the wrapping material and the interior panel.
[0006] According to an embodiment of the present utility model, an automotive interior panel edge-wrapping device includes a worktable, the worktable is fixedly installed, a rotating seat is rotatably installed on the worktable, a drive source that can drive the rotating seat to rotate is fixedly installed at the bottom of the worktable, and a pressing turntable that can press the workpiece against the rotating seat is driven to extend and retract above the worktable.
[0007] An edge-binding mechanism is provided, which is driven to extend and retract on one side of the worktable. The edge-binding mechanism includes an edge-binding box, which has an edge-binding opening on the side facing the rotating seat. A pair of edge-binding rollers are elastically and retractably arranged on the upper and lower sides of the edge-binding opening, and a gap is reserved between the two edge-binding rollers.
[0008] The technical principle of this utility model is as follows: An interior panel covered with packaging material is placed on a rotating base. A pressing turntable moves downwards to press against the interior panel for fixation. The edge-wrapping box moves horizontally until the edge-wrapping opening aligns with the side of the interior panel. The upper and lower edge-wrapping rollers simultaneously contact the edge of the interior panel and elastically compress as pressure increases. The upper edge-wrapping roller presses the packaging material downwards to the top edge of the interior panel, and the lower edge-wrapping roller presses the packaging material upwards to the bottom edge of the interior panel. With further movement, both the upper and lower edge-wrapping rollers pass over the upper and lower edges and further press the upper and lower surfaces of the interior panel until the edge-wrapping opening sidewall is pressed against the sidewall of the interior panel. A single operation can completely cover the side and both upper and lower surfaces of the interior panel with the packaging material, which is simple and convenient. After one side of the edge-wrapping is completed, the edge-wrapping mechanism retracts, and the drive source rotates the rotating base by a specified angle so that the unwrapped side aligns with the edge-wrapping opening. This process is repeated until multiple sides are wrapped, without the need to disassemble and reassemble the interior panel throughout the entire process.
[0009] Furthermore, the worktable is fixedly provided with mounting holes, the rotating seat is rotatably disposed in the mounting holes, and the drive source includes a servo motor, the output end of which is fixedly connected to the bottom of the rotating seat.
[0010] Furthermore, a mounting shell with an opening on one side is fixedly installed on the workbench, and a first cylinder is fixedly installed on the top of the mounting shell. The output end of the first cylinder is rotatably connected to the top of the pressing turntable.
[0011] Furthermore, the pressing turntable includes a pressure plate and a pressure plate. The pressure plate has a cavity that communicates with the bottom. The pressure plate is slidably disposed in the cavity, and the top of the pressure plate is connected to the top of the cavity by a plurality of first springs.
[0012] Furthermore, the edge-binding mechanism also includes a telescopic arm, one end of which is fixedly connected to the inner side of the mounting shell, and the other end of which is fixedly connected to the back side of the edge-binding box. A second cylinder is fixedly mounted on the telescopic arm, and the output end of the second cylinder is fixedly connected to the back side of the edge-binding box.
[0013] Furthermore, another edge-binding mechanism is provided on the other side of the worktable for driving telescopic extension, and the two edge-binding mechanisms are symmetrical to each other.
[0014] Furthermore, sliding grooves are fixedly provided on the upper and lower sides of the edge banding opening, and a sliding block is fixedly provided on the top of the roller frame of the edge banding roller. The sliding block can be embedded in the sliding groove and slide relative to it.
[0015] Furthermore, a plurality of second springs are fixedly connected to the bottom of the sliding groove, and the other end of the second springs is fixedly connected to the top of the sliding block.
[0016] Furthermore, a side pressure block is fixedly provided at the edge of the binding opening near the gap between the two binding rollers. A side pressure plate is rotatably connected to the bottom of the side pressure block, and the side pressure plate away from the rotation axis is fixedly connected to the side pressure block by several third springs.
[0017] Furthermore, the top surface of the rotating seat and the top surface of the edge-sealing roller located below are on the same plane.
[0018] Compared with existing technologies, this utility model has the following advantages: The pressing turntable moves downwards to press against the interior panel for fixation. Combined with the upper and lower elastically telescopic edge-sealing rollers, which are simultaneously compressed and deformed during horizontal advancement, the edge-sealing rollers can progressively press the interior panel from the side to the top and bottom, achieving complete coverage of three sides of the interior panel in a single action, effectively preventing the packaging material from peeling off and curling up. Furthermore, by setting a rotatable rotating seat in conjunction with a drive source, the interior panel is automatically rotated to switch processing surfaces after completing edge-sealing on one side, avoiding material displacement and surface damage caused by manual disassembly and flipping, significantly improving edge-sealing efficiency and bonding strength.

[0024] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0025] like Figure 1 As shown in the figure, this utility model embodiment proposes an automotive interior panel edge-wrapping device, including a worktable 1, which is fixedly installed. A rotating seat 2 is rotatably installed on the worktable 1. Specifically, the worktable 1 is fixedly provided with a mounting hole 12. The bottom of the rotating seat 2 is columnar and is embedded and rotatably installed in the mounting hole 12 for supporting the interior panel. The top shape of the rotating seat 2 can be adjusted according to the shape or size of the interior panel to increase its contact area with the bottom of the interior panel and ensure the bearing and fixing effect. The specific shape is not limited here.
[0026] like Figure 1 As shown, in this embodiment, a drive source capable of driving the rotating seat 2 to rotate is fixedly installed at the bottom of the workbench 1. The drive source includes, but is not limited to, a stepper motor, a servo motor, or other drive mechanisms capable of precisely controlling the rotation angle. In this embodiment, the drive source is set as a servo motor 21. The output end of the servo motor 21 is coaxially and fixedly connected to the bottom of the rotating seat 2 to drive the rotating seat 2 to rotate at a precise angle.
[0027] like Figure 1-4 As shown, in this embodiment, a pressing turntable 3 is driven to extend and retract above the worktable 1, which can press the workpiece against the rotating seat 2. This allows the workpiece to rotate at the same angle as the rotating seat 2 under the clamping and fixing of the pressing turntable 3 and the rotating seat 2, so as to change the orientation of the working surface. Specifically, a mounting shell 11 with an opening on one side is fixedly installed on the worktable 1. A first cylinder 31 is fixedly installed on the top of the mounting shell 11. The output end of the first cylinder 31 is rotatably connected to the top of the pressing turntable 3. The first cylinder 31 can clamp and fix or release the interior panel by driving the pressing turntable 3 to extend and retract up and down. The shape of the bottom of the pressing turntable 3 can be adapted to the shape of the top of the rotating seat 2 to form a stable clamping force. The specific shape is not limited here.
[0028] like Figure 1-4As shown in the figure, the automotive interior panel edge-wrapping device proposed in this embodiment of the utility model further includes an edge-wrapping mechanism 4. The edge-wrapping mechanism 4 is driven to extend and retract on one side of the workbench 1. The edge-wrapping mechanism 4 includes an edge-wrapping box 41 and a telescopic arm 44. The edge-wrapping box 41 is provided with an edge-wrapping opening 42 on the side facing the rotating seat 2, so that the cross-section of the edge-wrapping box 41 is U-shaped. A pair of edge-wrapping rollers 43 are elastically and retractably arranged on the upper and lower sides of the edge-wrapping opening 42, respectively. A working gap is reserved between the two edge-wrapping rollers 43. The top surface of the lower edge-wrapping roller 43 and the... The top surface of the rotating seat 2 is on the same plane. More specifically, sliding grooves 421 are fixedly provided on the upper and lower sides of the edge-sealing opening 42, and a sliding block 431 is fixedly provided on the top of the roller frame of the edge-sealing roller 43. The sliding block 431 can be embedded in the sliding groove 421 and slide relative to it. Several second springs 422 are fixedly connected to the bottom of the sliding groove 421. The other end of the second spring 422 is fixedly connected to the top of the sliding block 431. The second spring 422 can provide elastic resistance after the edge-sealing roller 43 is squeezed, thereby providing elastic resistance. The interior trim panel provides continuous pressure to complete the pressing and binding operation. The elasticity of the second spring 422 and the working gap reserved by the binding roller 43 can be adjusted according to the actual thickness and shape of the interior trim panel to adapt to interior trim panels of different sizes and obtain a better pressing effect. One end of the telescopic arm 44 is fixedly connected to the inner side of the mounting shell 11, and the other end is fixedly connected to the back side of the binding box 41. A second cylinder 45 is fixedly installed at the fixed end of the telescopic arm 44. The telescopic rod 451 of the second cylinder 45 is fixedly connected to the back side of the binding box 41. The cylinder 45 can achieve three-sided edge covering of the interior panel by driving the edge-covering box 41 to extend and retract. Specifically, during the process of contacting and pressing against the edge-covering box 41, the two edge-covering rollers 43 will move from the side of the interior panel near the center to the upper and lower corners respectively. As they move further, the two edge-covering rollers 43 will pass over the two corners. The second spring 422 is in a compressed state. Under the action of the second spring 422, the two edge-covering rollers 43 will continuously apply pressure to the upper and lower surfaces, thereby achieving three-sided edge covering of the interior panel in a single action, effectively preventing the packaging material from peeling off and curling up.
[0029] The technical principle of this utility model is as follows: The interior panel covered with packaging material is placed on the rotating seat 2. The pressing turntable 3 moves downward to press against the interior panel to fix it. The edge-wrapping box 41 moves horizontally until the edge-wrapping opening 42 is aligned with the side of the interior panel. The upper and lower edge-wrapping rollers 43 simultaneously contact the side of the interior panel and elastically compress as the pressure increases. The upper edge-wrapping roller 43 presses the packaging material downward to the top edge of the interior panel, and the lower edge-wrapping roller 43 presses the packaging material upward to the bottom edge of the interior panel. With further movement, the upper and lower edge-wrapping rollers 43 pass over the upper and lower edges and further press the upper and lower surfaces of the interior panel until the side wall of the edge-wrapping opening 42 is pressed against the side wall of the interior panel. The packaging material can completely cover the side and upper and lower surfaces of the interior panel in a single operation, which is simple and convenient. After one side of the edge-wrapping is completed, the edge-wrapping mechanism 4 retracts, and the servo motor 21 drives the rotating seat 2 to rotate at a specified angle so that the unwrapped side is aligned with the edge-wrapping opening 42. The above process is repeated until the multi-side wrapping is completed. The interior panel does not need to be disassembled and reinstalled throughout the process.
[0030] This invention achieves fixation by pressing the interior panel with the downward movement of the pressing turntable 3. Combined with the elastically telescopic edge-sealing roller 43, which is compressed and deformed synchronously during the horizontal advancement, the edge-sealing roller 43 can press the interior panel step by step from the side to the top and bottom. A single action can achieve complete coverage of three sides of the interior panel, effectively preventing the packaging material from peeling off and curling up. Furthermore, by setting a rotatable rotating seat 2 and cooperating with a servo motor 21 to precisely control the rotation angle, the interior panel is automatically rotated to switch the processing surface after completing the edge-sealing on one side. This avoids the displacement of the packaging material and surface damage caused by manual disassembly and flipping, and significantly improves the edge-sealing efficiency and bonding firmness.
[0031] like Figure 1 and Figure 3 As shown, according to another embodiment, the pressing turntable 3 includes a pressure plate 32 and a pressure plate 33. The pressure plate 32 is provided with a cavity 35 communicating with the bottom. The pressure plate 33 is slidably disposed in the cavity 35, and the top of the pressure plate 33 is connected to the top of the cavity 35 by a plurality of first springs 34. The pressure plate 33 can elastically extend and retract within the pressure plate 32 under the action of the first springs 34. Based on the above improvement, when the pressure plate 33 presses and fixes the interior panel, the first springs 34 will provide elastic buffering to avoid damage to the interior panel covering material caused by rigid compression of the pressure plate 33. The bottom of the pressure plate 33 and the top of the rotating seat 2 can also be coated with a flexible anti-slip material, such as rubber, PVC, etc., to increase the friction between the pressure plate 33, the rotating seat 2 and the interior panel, and ensure that the interior panel can be driven to rotate stably.
[0032] like Figure 1 and Figure 4As shown, according to another embodiment, another edge-wrapping mechanism 4 is driven to extend and retract on the other side of the workbench 1. The two edge-wrapping mechanisms 4 are symmetrical to each other. Based on the above improvement, the two edge-wrapping mechanisms 4 can wrap the interior panel at the same time. The uniform force on both sides is conducive to maintaining the stability of the edge wrapping of the interior panel and avoiding the possible slippage or deformation of the packaging material caused by the force on one side of the interior panel. In addition, the rotating seat 2 only needs to rotate once to complete the wrapping of all four sides, which greatly improves the edge-wrapping efficiency.
[0033] like Figure 1 and Figure 4 As shown, according to another embodiment, further, a side pressure block 46 is fixedly provided on the side wall of the edge-sealing opening 42 near the gap between the two edge-sealing rollers 43. A side pressure plate 47 is rotatably connected to the bottom of the side pressure block 46. The side pressure plate 47 can rotate to fit against the side pressure block 46. The side of the side pressure plate 47 away from the rotation axis is fixedly connected to the side pressure block 46 by several third springs 471. Based on the above improvement, due to the compression characteristics of the third springs 471, the side pressure plate 47 will be pushed up by the third springs 471 and present an inclined state when it is not under force. When the interior trim panel abuts against the edge-sealing rollers 43, both the upper edge-sealing roller 43 and the lower edge-sealing roller 43 pass over the upper and lower edges and press the upper and lower surfaces of the interior trim panel. When the interior panel sidewall is compressed, it extends into the edge opening 42 and contacts and abuts against the upper part of the side pressure plate 47. With further relative movement, the side pressure plate 47 rotates in the direction of the third spring 471 and gradually increases the contact area with the interior panel sidewall cladding material, thereby pressing the interior panel sidewall cladding material from top to bottom until it is completely pressed against the interior panel sidewall. Since the third spring 471 has a certain axial volume no matter how it is compressed, the side pressure block 46 is provided with a relief groove 461 on the side away from the rotation axis. The bottom of the third spring 471 is fixedly connected to the bottom of the relief groove 461. The relief groove 461 can provide accommodating space when the spring is compressed, ensuring that the side pressure plate 47 can be completely pressed against the interior panel sidewall.
[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
