Description

Technical Field

[0001] This utility model relates to the field of automated production machinery technology, specifically to an automotive leather flat-laying and transport device. Background Technology

[0002] In the automotive interior manufacturing industry, leather, as a high-end material, is widely used in the covering of components such as seats and steering wheels. Currently, the industry commonly uses automated integrated laying and cutting equipment to process leather materials. This type of equipment typically includes a conveying mechanism, a tensioning and leveling module, and a cutting execution unit, which can automatically complete the laying, stretching, shaping, and cutting of leather, effectively improving production efficiency and reducing the labor intensity of manual operation.

[0003] However, existing leather flat-lay cutting devices still have certain limitations in practical applications. Due to the inherent elasticity of leather, although it is stretched and flattened by the tensioning mechanism during transport before entering the cutting station, the residual stress within the material after cutting causes varying degrees of elastic shrinkage. This shrinkage results in deviations between the final cut leather parts and the design dimensions, affecting the accuracy of subsequent sewing and assembly, and potentially leading to decreased part consistency, especially in large-scale continuous production.

[0004] Furthermore, most existing equipment lacks an effective finished product transfer mechanism after cutting. Cut leather pieces typically remain on the processing table, failing to directly connect with the transport system. Secondary picking and transfer by manual labor or additional robotic arms is required, increasing production cycle time and increasing the risk of positioning errors or surface scratches due to secondary operations. This discontinuous processing method limits the overall automation level and process continuity of the production line, hindering the application requirements of high-cycle, high-quality manufacturing scenarios.

[0005] Therefore, a vehicle leather flat-laying transportation device is proposed. Summary of the Invention

[0006] The purpose of this utility model is to provide an automotive leather flat-laying and transporting device to solve the problems in the prior art where the leather is deformed when it is laid flat, causing the cut leather to spring back and affecting the cutting accuracy. In addition, the cut leather in the prior art still remains on the processing table and cannot be directly connected to the transport system, which limits the automation level and process continuity of the overall production line.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A vehicle leather flat-laying transport device includes a frame, a traction frame, a traction component, a support component, a lower pressing frame, and a moving component. The lower pressing frame is fixedly connected to the upper end of the frame. The traction frame is slidably connected to the left end of the upper and lower pressing frames of the frame. The traction component is mounted on the traction frame and is used to drive the traction frame to clamp the leather and move it to the left to a specified distance, then release the leather and drive the traction frame to return to its original position to the right. The support component is connected between the traction frame and the lower pressing frame and is used to evenly support the leather when the traction frame clamps and moves. The traction frame is also equipped with a cutting component, which cuts the leather after the traction frame has fully returned to its original position. The moving component is located on the left side of the frame and is used to transport the cut leather out of the frame.

[0009] Preferably, the traction component includes a traction guide rail, a drive device, and a clamping unit. The traction guide rail is located on both sides of the frame, and the traction frame is slidably connected to the traction guide rail. The drive device is located inside the traction frame to drive the traction frame to move left and right on the traction guide rail. The clamping unit is located inside the traction frame to clamp the leather when the traction frame moves to the left.

[0010] In the above scheme, the drive device can drive the traction frame to move left and right on the frame. The traction frame is also equipped with a distance sensor to provide feedback on the distance between the traction frame and the lower pressing frame, and thus provide feedback on the length of the leather displacement pulled by the traction frame, so that the length of the leather pulled by the traction frame can be detected and controlled.

[0011] Preferably, the clamping unit includes a leather groove and a clamping plate, the leather groove being formed on the traction frame, and the clamping plate being disposed at the upper end of the leather groove.

[0012] In the above scheme, when it is necessary to clamp the leather with the traction frame so that the traction frame can move the leather to the left, the extension end of the hydraulic cylinder extends, causing the clamping plate to move downward and fit against the leather, thereby clamping the leather between the clamping plate and the inner wall of the traction frame; when the traction frame pulls the leather to the left and lays it flat to the specified length, the extension end of the hydraulic cylinder retracts, causing the clamping plate to lift up and release the leather, and then the traction device drives the traction frame to move to the right and reset. At this time, the left end of the leather will pass through the leather groove on the traction frame and hang down naturally on the moving track below under its own weight, which is convenient for subsequent cutting and direct removal from the frame by the moving parts.

[0013] Preferably, the support component includes a support frame, a support surface, and a support connector. Several support frames are provided, and the lower ends of the several support frames are slidably connected to the traction guide rail. The support surface is connected between the traction frame and the lower pressure frame, and the lower end of the support surface is in contact with the upper end of the support frame. The support connector is connected to the support frame.

[0014] In the above scheme, the support frame can evenly support the support surface and the lower end of the leather, and the support connector can ensure that when the traction frame moves to the left or right, the support frame between the traction frame and the lower pressure frame can be evenly distributed between the traction frame and the lower pressure frame.

[0015] Preferably, the lower pressure frame is further provided with a lower pressure plate, which is used to press the right end of the leather when the traction frame returns to the right.

[0016] In the above scheme, the lower pressure plate is used to press the right end of the leather when the traction frame returns to the right. The lower pressure plate is driven by a hydraulic cylinder, so that after the traction frame pulls the leather to the left and lays it flat to a specified length, the hydraulic cylinder drives the lower pressure plate to extend, so that the lower pressure plate presses the leather located at the lower pressure frame after it is laid flat. This makes it easier to prevent the leather from moving to the right when the traction frame moves to the right to return to the right after releasing the leather, thereby ensuring the cutting accuracy of the leather.

[0017] Preferably, the cutting component includes a cutting frame, a cutting guide groove, and a cutting wheel. The cutting frame is fixedly connected to the left end of the traction frame. The cutting guide groove is formed on the cutting frame and its upper part communicates with the leather groove. The cutting wheel is disposed inside the cutting frame and cooperates with the cutting guide groove.

[0018] Preferably, the moving component includes a moving track and a drive motor, the moving track being mounted on the frame and the drive motor being fixed to the left end of the frame.

[0019] In the above scheme, the drive motor can drive the moving track to rotate. After the leather is cut, the drive motor can be turned on directly to drive the moving track to work, so that the leather on the moving track moves to the left and is finally removed from the frame for subsequent processing.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] By setting up a traction frame and traction components on the frame, the leather on the frame is pulled and laid flat. A support component is set between the traction frame and the lower pressing frame so that the lower end of the leather can be evenly supported by the support component during the pulling process. This prevents the leather from deforming in the middle section due to its own weight and uneven bottom support during the pulling and laying process, which would affect the accuracy of the cut leather. After the leather is laid flat, the traction frame is reset before cutting, so that the cut leather can hang naturally on the moving component. After the cut leather is completed, it can be picked up and transferred at any time as needed by the moving component. Attached Figure Description

[0031] To ensure a clear and complete description of the technical solutions in the embodiments of this utility model, and to make the features and advantages more apparent and understandable, the specific implementation methods of this utility model are described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Example

[0032] Please see Figures 1 to 2A vehicle leather flat-laying transport device is provided for flat-laying and transporting leather. It includes a frame 1, a traction frame 2, a traction component 3, a support component 4, a lower pressure frame 5, and a moving component 6. The lower pressure frame 5 is fixedly connected to the upper end of the frame 1. The traction frame 2 is slidably connected to the left end of the upper and lower pressure frames 5 of the frame 1. The traction component 3 is disposed on the traction frame 2 and is used to drive the traction frame 2 to clamp the leather and move it to the left to a specified distance, then release the leather and drive the traction frame 2 to return to its original position to the right. The support component 4 is connected between the traction frame 2 and the lower pressure frame 5 to evenly support the leather when the traction frame 2 clamps and moves the leather. The traction frame 2 is also provided with a cutting component 7, which cuts the leather after the traction frame 2 has fully returned to its original position. The moving component 6 is disposed on the left side of the frame 1 and is used to transport the cut leather out of the frame 1.

[0033] Specifically, a leather feeding mechanism is also provided at the right end of the frame 1 to fix the leather roll and convey the leather towards the frame 1. The traction component 3 is used to pull and lay the leather conveyed by the feeding mechanism. The purpose of the support component 4 in supporting the leather evenly is to provide a uniform support to the bottom of the laid leather, effectively preventing the leather from lacking support in the middle when it is pulled to the left by the traction component 3, which would cause the leather to deform under the action of gravity. As a result, after the traction component 3 releases the leather, the leather will rebound under its own elasticity, causing the size of the leather laid out by the traction component 3 to change.

[0034] Please see Figures 2 to 5 The traction component 3 includes a traction guide rail 31, a drive device, and a clamping unit 32. The traction guide rail 31 is located on both sides of the frame 1. The traction frame 2 is slidably connected to the traction guide rail 31. The drive device is located inside the traction frame 2 to drive the traction frame 2 to move left and right on the traction guide rail 31. The clamping unit 32 is located inside the traction frame 2 to clamp the leather when the traction frame 2 moves to the left.

[0035] Please see Figures 1 to 3 Specifically, the drive device is based on existing technology and can employ a combination of wheels and a motor. When the motor drives the wheels to rotate within the traction frame 2, the wheels roll on the guide rail 31, thereby causing the traction frame 2 to move relative to the guide rail on the frame 1. Alternatively, a combination of a belt and a motor can be used, connecting the traction frame 2 to the belt. When the motor drives the belt, the belt moves, causing the traction frame 2 to move left and right. The drive device is not limited to the two methods mentioned above; it only needs to be able to move the traction frame 2 left and right on the frame 1. A distance sensor is also installed on the traction frame 2 to provide feedback on the distance between the traction frame 2 and the lower pressure frame 5, thereby providing feedback on the length of the leather displacement pulled by the traction frame 2. This allows the length of the leather displacement pulled by the traction frame 2 to be detected and controlled.

[0036] Please see Figures 3 to 4The clamping unit 32 includes a leather groove 321 and a clamping plate 322. The leather groove 321 is formed on the traction frame 2, and the clamping plate 322 is set on the upper end of the leather groove 321. The clamping plate 322 is driven to move up and down by a hydraulic cylinder. The hydraulic cylinder is fixed on the frame 1. The hydraulic cylinder is not shown in the figure. When it is necessary to clamp the leather with the traction frame 2 so that the traction frame 2 can drive the leather to move to the left, the extension end of the hydraulic cylinder extends, driving the clamping plate 322 to move downward and fit against the leather, thereby clamping the leather between the clamping plate 322 and the inner wall of the traction frame 2. When the traction frame 2 pulls the leather to the left and lays it flat to the specified length, the extension end of the hydraulic cylinder retracts, causing the clamping plate 322 to lift up and release the leather. Then the traction device drives the traction frame 2 to move to the right and reset. At this time, the left end of the leather will pass through the leather groove 321 on the traction frame 2 and hang down naturally on the moving track 61 below under its own weight, so that it can be directly removed from the frame 1 by the moving part 6 after subsequent cutting.

[0037] Please see Figure 3 The support component 4 includes a support frame 41, a support surface 42, and a support connector. Several support frames 41 are provided, and the lower ends of several support frames 41 are slidably connected to the traction guide rail 31. The support surface 42 is connected between the traction frame 2 and the lower pressure frame 5. The lower end of the support surface 42 is in contact with the upper end of the support frame 41. The support connector is connected to the support frame 41.

[0038] Please see Figures 2 to 3 Specifically, in the accompanying drawings of this application, six support frames 41 are provided. The specific number of support frames 41 can be reasonably adjusted as needed. It is only necessary to ensure that when the traction frame 2 stretches the leather and lays it flat, the support frames 41 can evenly support the support surface 42 and the lower end of the leather. The support surface 42 is a rollable fabric with a certain degree of elasticity. The roll-up end of the support surface 42 can be arbitrarily set inside the traction frame 2 or set at the lower pressure frame 5. The other end is connected to the lower pressure frame 5 or the traction frame 2. It is only necessary to ensure that when the traction frame 2 moves to the left, the support surface 42 can unfold on the support frame 41 as the traction frame 2 moves, so as to support the leather above. When it moves to the right, the support surface 42 retracts towards the roll-up end.

[0039] Specifically, the support connectors can ensure that, as the traction frame 2 moves away from or towards the lower pressure frame 5, several support frames 41 between the traction frame 2 and the lower pressure frame 5 are evenly distributed at the lower end of the support surface 42, that is, evenly distributed under the laid leather. This ensures that when the traction frame 2 pulls the leather to the left and lays it flat, the lower end of the leather can be evenly supported, reducing the possibility of deformation of the leather due to its own weight during traction. The support connectors can use a cross-linking method to connect adjacent support frames 41, the traction frame 2, and the lower pressure frame 5, with the intersection point of the cross-links located at the center of the link; alternatively, a coil can be installed on the side of the support frame 41, along with a sensor. The selection of the support connectors is not limited to the above two methods; it is only necessary to ensure that the support frames 41 between the traction frame 2 and the lower pressure frame 5 are evenly distributed between the traction frame 2 and the lower pressure frame 5 when the traction frame 2 moves to the left or right.

[0040] Please see Figures 3 to 5 The lower pressing frame 5 is also equipped with a lower pressing plate 51. The lower pressing plate 51 is used to press the right end of the leather when the traction frame 2 returns to the right. The lower pressing plate 51 is driven by a hydraulic cylinder, so that after the traction frame 2 pulls the leather to the left and lays it flat to the specified length, the hydraulic cylinder drives the lower pressing plate 51 to extend, so that the lower pressing plate 51 presses the leather located at the lower pressing frame 5 after it is laid flat. This makes it easier for the traction frame 2 to move to the right and return to the right after releasing the leather, and prevents the leather from moving to the right, thereby ensuring the cutting accuracy of the leather.

[0041] Please see Figures 3 to 6 The cutting component 7 includes a cutting frame 71, a cutting guide groove 72, and a cutting wheel 73. The cutting frame 71 is fixedly connected to the left end of the traction frame 2. The cutting guide groove 72 is opened on the cutting frame 71, and the upper part of the cutting guide groove 72 communicates with the leather groove 321. The cutting wheel 73 is set inside the cutting frame 71 and cooperates with the cutting guide groove 72.

[0042] Specifically, the cutting guide groove 72 is connected to the leather groove 321. After the traction frame 2 moves the leather to the left and lays it flat to the specified length, when the traction frame 2 releases the leather and moves to the right to reset, the leather at the traction frame 2 can follow the leather groove 321, pass through the cutting guide groove 72, and finally fall naturally onto the moving track 61. The cooperation between the cutting wheel 73 and the cutting guide groove 72 means that after the traction frame 2 has completely reset to the right, the cutting wheel 73 starts to work and separates the leather at the left end of the cutting guide groove 72 from the leather at the right end, thereby achieving the cutting of the leather. This ensures that the leather is not taut during cutting, effectively preventing the leather from springing back after cutting in a taut state, and ensuring the cutting accuracy of the leather.

[0043] Please see Figures 7 to 8The moving part 6 includes a moving track 61 and a drive motor 62. The moving track 61 is mounted on the frame 1, and the drive motor 62 is fixed to the left end of the frame 1. The drive motor 62 can drive the moving track 61 to rotate. After the leather is cut, the drive motor 62 can be turned on directly to drive the moving track 61 to work, so that the leather on the moving track 61 moves to the left and is finally removed from the frame 1 for subsequent processing.

[0044] Working process: When it is necessary to lay the leather flat for cutting, first install the leather roll on the right end of the frame 1, then place the leather end under the right end of the press frame 5 of the frame 1. The leather is clamped by the clamping plate 322 on the traction frame 2. Then the drive device in the traction component 3 starts to work, driving the traction frame 2 to move to the left. With the cooperation of the clamping plate 322, the traction frame 2 clamps the leather and moves to the left to lay it flat until the traction frame 2 moves to the designated position and the leather is laid flat to the designated length. Then the clamping plate 322 on the traction frame 2 releases its grip on the leather and presses down. The lower pressure plate 51 of frame 5 presses the leather on the upper right of frame 1. Finally, the traction frame 2 moves to the right and resets. The leather at the traction frame 2 can follow the leather groove 321, pass through the cutting guide groove 72, and finally fall naturally onto the moving track 61. After the traction frame 2 is completely reset to the right, the cutting wheel 73 starts to work and separates the leather at the left end of the cutting guide groove 72 from the leather at the right end, thereby achieving the cutting of the leather. This ensures that the leather is not taut during cutting, effectively preventing the leather from springing back after cutting when it is taut, and ensuring the cutting accuracy of the leather. The support component 4 between the traction frame 2 and the lower pressure frame 5 ensures that the force on the support surface 42 between the traction frame 2 and the lower pressure frame 5 is uniform during the movement of the traction frame 2 to the left or right. This prevents the leather on the support surface 42 from deforming when stretched and laid flat due to its own weight and uneven support at the bottom, effectively improving the cutting accuracy of the leather. After cutting, the cut leather will naturally fall onto the moving track 61, which will drive the moving track 61 to move the leather to the left and eventually remove it from the frame 1. No manual operation is required, which further improves the effect and efficiency of automated production.
