Description

Technical Field

[0001] The present invention relates to the technical field of automobile interior processing, in particular to a cutting device for automobile interior processing. Background Art

[0002] In the processing of automotive interior leather, traditional die-cutting suffers from high costs, low efficiency, and poor precision. Laser cutting technology, as an emerging processing method, offers significant advantages. It utilizes a high-power density laser beam to irradiate the leather, rapidly heating the material to its vaporization temperature. As the beam moves, continuous holes are formed, completing the cut. Laser cutting of automotive interior leather offers precise and delicate cutting, high efficiency, and the ability to cut complex patterns. The resulting smooth, burr-free cutting edges eliminate the need for subsequent processing. This technology effectively improves product quality and production efficiency, reduces costs, and meets the personalized and diverse design needs of automotive interiors. Consequently, it has found widespread application in the automotive interior leather processing field.

[0003] Chinese patent publication number CN119501314A discloses an intelligent cutting device for processing new energy vehicle interiors, relating to the technical field of intelligent cutting devices, comprising: a cutting section; a sorting section provided inside the cutting section; and a connecting section provided outside the cutting section. A fixed frame is installed inside a raised frame to facilitate the movement of an auxiliary displacement frame, so that the vehicle interior can be moved after being bonded to the adhesive block, thereby sorting the cut vehicle interior without human intervention. This solves the problem of conventional interior cutting devices that, after cutting, it is difficult to separate the cut product from the remaining material, resulting in the two being discharged together with the conveying component and requiring human labor to perform separate sorting outside the device, making the cutting process overly complicated. However, the above patent document still has the following defects during implementation:

[0004] Although the above patent facilitates sorting by staff during implementation, it lacks relevant structures to adaptively adjust the tension of leather of different materials when laser cutting patterns on automotive interior leather. The cutting accuracy is easily affected by the looseness and wrinkles of the leather. At the same time, it is impossible to use a non-contact method to partition and absorb the leather from multiple sources, which makes the leather prone to displacement and deformation during the cutting process.

[0031] Example 1, as Figure 1 and Figure 2 As shown, a cutting device for automobile interior processing includes a shell 1, the inner surface of the shell 1 is rotatably connected to a cover 2, the four corners of the lower end of the shell 1 are fixedly connected to support legs 3, the inner surface of the shell 1 is fixedly connected to a base plate 7, the inner surface of the shell 1 is fixedly mounted with a laser cutting mechanism 4 above the base plate 7, the inner surface of the base plate 7 and the inner cavity of the shell 1 are jointly provided with a tension pulling component 5, and the inner surface of the base plate 7 is provided with an adsorption positioning component 6.

[0032] During the implementation of this embodiment, the four corners of the leather used for automobile interior are respectively placed at the four corners of the tension pulling component 5, and then the four corners of the leather are fixed by the tension pulling component 5, and then driven to move backward. During the movement, the tension is automatically adjusted according to the material properties of the leather itself. Then, the lower end of the leather is subjected to multi-source negative pressure adsorption in a partitioned manner by the adsorption positioning component 6, and the position of the leather is positioned, and the laser cutting mechanism 4 is used to cut circular holes in the leather.

[0033] The laser cutting mechanism 4 mentioned above is a mature laser cutting technology means and equipment in the prior art. In this solution, it is used to perform laser cutting operations by freely moving on the X-axis, Y-axis and Z-axis, and its internal structure, principle and connection method are no longer explained.

[0034] Specifically, in order to achieve adaptive adjustment of the tension of automobile leather, refer to Figure 3 、 Figure 4 、 Figure 5 and Figure 6 In this embodiment, the tension pulling assembly 5 includes an electric cylinder 51 fixedly connected to the front inner surface of the shell 1, an expansion mechanism 52 is provided on the inner surface of the bottom plate 7, and a clamping and fixing mechanism 53 and an up and down swinging mechanism 54 are symmetrically provided at the upper end angle of the expansion mechanism 52.

[0035] For further information, see Figure 3 and Figure 6 In this embodiment, the clamping and fixing mechanism 53 includes two spring telescopic rods 531 fixedly connected to the left end of the square rod block 528, and the left ends of the two spring telescopic rods 531 are commonly fixedly connected to a concave plate 532, the upper end of the concave plate 532 is fixedly connected to the electric cylinder 2 533, and the lower end of the electric cylinder 2 533 is fixedly connected to a fixed plate 534 that is slidably connected to the concave plate 532.

[0036] For further information, see Figure 3 、 Figure 4 and Figure 5 In this embodiment, the expansion mechanism 52 includes a push rod 521 fixedly connected to the rear end of the electric cylinder 51, and the outer surface of the push rod 521 is slidably connected to the guide rod 522. The inner surface of the guide rod 522 is provided with four annular holes 523, and guide grooves 524 are provided at the four corners of the upper end of the bottom plate 7. The inner surfaces of the four annular holes 523 are slidably connected to annular blocks 525, and the inner surfaces of the four annular blocks 525 are fixedly connected to round rods 526 slidably connected to the guide grooves 524. The outer surface of the push rod 521 is sleeved with a spring 527, and the two ends of the spring 527 are respectively fixedly connected to the front end of the guide rod 522 and the round blocks on the push rod 521, and the inner surfaces of the four round rods 526 are slidably connected to square rod blocks 528.

[0037] During the implementation process, the four corners of the leather are placed one by one on the inner surface of the concave plate 532, and then the electric cylinder 2 533 is immediately started each time a corner is placed to push the fixing plate 534 downward until the fixing plate 534 fixes the leather. When the four corners of the leather are fixed, the electric cylinder 1 51 is started to push the push rod 521 to move backward, and the guide rod 522 is pushed backward under the action of the spring 1 527. Since the distance between the inner surfaces of the guide grooves 524 on both sides gradually increases from the front to the back, the two round rods 526 drive the annular block 525 to slide on the inner surface of the annular hole 523 under the limiting action of the guide grooves 524. When the round rods When 526 moves to the horizontal plane of the guide groove 524, the fixed leather is pulled on both sides, and the deformation of the spring telescopic rod 531 allows the leather to automatically adjust its tension according to its own material properties during the pulling process. On the one hand, it can avoid damage to the leather, and on the other hand, it can ensure that the tension of the leather is always in a suitable state, effectively preventing the leather from being damaged due to excessive tension during the cutting process. At the same time, it ensures that the leather is always in a suitable tension state to prevent relaxation and wrinkles from affecting the cutting accuracy, thereby improving the accuracy and quality of laser cutting of automotive interior leather and meeting the fine and high-standard cutting requirements of automotive interiors.

[0038] For further information, see Figure 3 and Figure 6 In this embodiment, the up and down swinging mechanism 54 includes a raised plate 541 fixedly connected to the inner surface of the shell 1 symmetrically on the left and right sides, the lower ends of the four square rod blocks 528 are fixedly connected to the roller 542, and the outer surfaces of the four square rod blocks 528 are each provided with a spring 2 543, and the two ends of the four spring 2 543 are respectively fixedly connected to the upper end of the roller 542 and the round block on the outer surface of the round rod 526.

[0039] As can be seen from the above, after the leather maintains a suitable tension state, it will continue to move backward. At this time, the roller 542 at the lower end of the square rod block 528 will be squeezed by the arc protrusion on the raised plate 541, and the spring 2 543 is in a deformed state, causing the square rod block 528 to slide up and down on the inner surface of the round rod 526, driving the leather to swing up and down, which helps to release the internal tension that may be generated in the leather during the tensioning process and prevent deformation after cutting. The up and down swinging can adjust the swing amplitude according to the thickness and elasticity of the leather to meet the cutting requirements of different materials.

[0040] The rollers 542 mentioned above contact the arc-shaped protrusions on the raised plate 541 , so that when the two rollers 542 at the front move to the highest point of the arc-shaped protrusions on the raised plate 541 , the two rollers 542 at the rear move to the lowest point of the raised plate 541 .

[0041] Embodiment 2: Based on embodiment 1, this embodiment adds an adsorption and positioning component 6 for performing zoned multi-source adsorption and positioning on the leather for automobile interior, thereby achieving the purpose of performing zoned multi-source adsorption and positioning on the leather for automobile interior.

[0042] Specifically, in order to perform multi-source adsorption positioning on the leather used for automotive interior, refer to Figure 3 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10 In this embodiment, the adsorption positioning assembly 6 includes an extrusion plate 61 fixedly connected to the rear end of the push rod 521, a lifting mechanism 62 is provided on the inner surface of the bottom plate 7, a partitioning mechanism 63 is provided on the inner surface of the lifting mechanism 62, and an exhaust mechanism 64 is provided on the rear part of the inner surface of the shell 1.

[0043] For further information, see Figure 3 、 Figure 7 and Figure 8 In this embodiment, the lifting mechanism 62 includes a partition frame 621 fixedly connected to the inner surface of the base plate 7, the inner surface of the partition frame 621 is slidably connected to a sliding frame 622, the upper end of the sliding frame 622 is fixedly connected to a rubber strip 623, and the lower end of the sliding frame 622 is fixedly connected to a hemispherical rod 624 slidably connected to the inner surface of the partition frame 621, and the outer surface of the hemispherical rod 624 is provided with a spring three 625, and the two ends of the spring three 625 are respectively fixedly connected to the lower end of the partition frame 621 and the hemisphere on the hemispherical rod 624.

[0044] For further information, see Figure 3 and Figure 9 In this embodiment, the partitioning mechanism 63 includes a plurality of alloy circular hole plates 631 fixedly connected to the inner surface of the sliding frame 622, the circular holes at the lower ends of the plurality of alloy circular hole plates 631 are fixedly connected to cylinders 632, and the inner surfaces of the plurality of cylinders 632 on the same side are commonly fixedly connected to ventilation pipes 633, and the upper ends of the ventilation pipes 633 are located in the inner cavity of the cylinder 632 and are fixedly connected to a plurality of solenoid valves 634.

[0045] During the implementation process, when the round rod 526 moves to the rear part of the inner surface of the guide groove 524, the leather moves to the set position, and the guide rod 522 can no longer move backward. The electric cylinder 51 continues to push the push rod 521 to move backward. At this time, the spring 527 will gradually be in a compressed state. During the movement of the push rod 521 backward, the inclined surface of the extrusion plate 61 will squeeze the hemisphere at the lower end of the hemispherical rod 624, so that the hemispherical rod 624 will gradually move upward to push the sliding frame 622 to slide on the inner surface of the partition frame 621, and the rubber strip 623 and the alloy circular hole plate 631 will be tightly attached to the lower end of the leather.

[0046] For further information, see Figure 3 and Figure 10 In this embodiment, the exhaust mechanism 64 includes a connecting plate 641 fixedly connected to the rear part of the inner surface of the outer shell 1, and the inner surface of the connecting plate 641 is symmetrically fixedly connected to the hollow cylinder 642. The inner surfaces of the two hollow cylinders 642 are slidably connected to the piston pull rod 643 which is slidably connected to the connecting plate 641. The outer surfaces of the two piston pull rods 643 are both sleeved with spring four 644, and the two ends of the two spring four 644 are respectively fixedly connected to the piston on the piston pull rod 643 and the lower part of the inner surface of the hollow cylinder 642. The upper part of the inner surface of the two hollow cylinders 642 is fixedly connected to a connecting pipe 646 fixedly connected to the ventilation pipe 633, and the upper part of the inner surface of the two hollow cylinders 642 is fixedly connected to the solenoid valve two 647.

[0047] For further information, see Figure 3 and Figure 10 In this embodiment, the upper ends of the two piston pull rods 643 are fixedly connected to the inclined plate 648, and the left and right ends of the extrusion plate 61 are symmetrically fixedly connected to the extrusion rods 645.

[0048] During the implementation process, when the rubber strip 623 and the alloy circular hole plate 631 are tightly attached to the lower end of the leather, the push rod 521 continues to be pushed backward. At the same time, the hemisphere at the lower end of the hemisphere rod 624 will move to the horizontal position of the extrusion plate 61. The backward movement of the extrusion plate 61 will drive the extrusion rod 645 to move backward, and in the process of movement, the inclined surface on the inclined plate 648 will be squeezed, so that the inclined plate 648 pushes the piston rod 643 downward to move. At the same time, the piston rod 643 will slide downward on the inner surface of the hollow cylinder 642, and the spring four 644 will be in a compressed state. The air inside the cylinder 632 is extracted through the cooperation of the vent pipe 633, the connecting pipe 646 and the solenoid valve 634, so that the inside of the cylinder 632 is in a negative pressure state, and the lower end of the leather can be tightly adsorbed on the upper end of the alloy circular hole plate 631, so that the leather can maintain a stable position during the subsequent laser cutting process, avoiding cutting errors caused by slight displacement or shaking of the leather, and effectively preventing burrs, unevenness and incomplete cutting on the cutting edge. At the same time, the non-contact adsorption method is adopted, which will not cause scratches or indentations on the leather surface, effectively protecting the surface quality of the leather.

[0049] Secondly, in the process of laser cutting circular holes in leather, the laser will cut one by one. When the leather position adsorbed on the upper end of a cylinder 632 is cut, this place will come into contact with the outside air. At the same time, this position is no longer in a negative pressure state. Through several cylinders 632, the uncut areas can still be tightly attached to the upper end of the alloy circular hole plate 631. Through multiple adsorption sources, the uncut areas can still be tightly attached to the alloy circular hole plate 631, which can keep the leather stable during the cutting process, reduce the displacement and deformation of the leather caused by the loss of local negative pressure, and thus improve the cutting accuracy and quality.

[0050] In addition, when the cutting is completed, the electric cylinder 51 will drive the extrusion plate 61 to reset, and the piston pull rod 643 will reset under the compression reaction of the spring four 644, slide upward on the inner surface of the hollow cylinder 642, squeeze the air in the hollow cylinder 642, and discharge it through the solenoid valve two 647.

[0051] The rubber strip 623 mentioned above can be subjected to high temperature resistance and fireproof coating on the surface in this solution.

[0052] The solenoid valve 1 634 and the solenoid valve 2 647 mentioned above are mature one-way control technical means and equipment in the prior art. In this solution, they are used to control the flow direction of the gas, and their internal structure, principle and connection method are no longer explained.

[0053] Working process: When in use, the leather is fixed by the mutual cooperation between the clamping and fixing mechanism 53 and the expansion mechanism 52, and the tension is adaptively adjusted after fixation. Then, the leather is driven to swing by the up and down swinging mechanism 54 to evenly distribute the stress generated by the leather tension. The lifting mechanism 62 is tightly attached to the lower end of the leather, and the partitioning mechanism 63 and the exhaust mechanism 64 perform multi-source adsorption and fixing operations on the lower end of the leather.
