Description

Technical Field

[0001] This invention relates to the field of automotive interior processing technology, and in particular to a cutting device for automotive interior processing. Background Technology

[0002] In automotive interior leather processing, traditional die-cutting suffers from high costs, low efficiency, and poor precision. Laser cutting technology, as an emerging processing method, offers significant advantages. Its principle involves using 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, thus completing the cut. Laser cutting of automotive interior leather offers advantages such as precise and delicate cutting, high efficiency, the ability to cut complex patterns, and smooth, burr-free edges without the need for post-processing. It effectively improves product quality and production efficiency, reduces costs, and meets the personalized and diverse design needs of automotive interiors, thus finding widespread application in the automotive interior leather processing field.

[0003] Chinese Patent Publication No. CN119501314A discloses an intelligent cutting device for processing interior materials of new energy vehicles, relating to the technical field of intelligent cutting devices. The device includes: a cutting section; a sorting section inside the cutting section; and a connecting section outside the cutting section. By installing a fixed frame inside a raised frame to facilitate the movement of an auxiliary displacement frame, the automotive interior materials are moved after being adhered to the adhesive block. This allows for sorting of the cut automotive interior materials without manual intervention, solving the problem of traditional interior material cutting devices where it is inconvenient to separate the cut products from the leftover material after cutting, resulting in both being discharged together with the conveying components. Furthermore, manual sorting is required outside the equipment, making the cutting process overly complex. However, the aforementioned patent still has the following drawbacks in practice:

[0004] While the aforementioned patent facilitates sorting by staff during implementation, it lacks a structure to adaptively adjust the tension of different leather materials when laser-cutting patterns on automotive interior leather. This makes it easy for leather looseness and wrinkles to affect cutting accuracy. Furthermore, it cannot use a non-contact method to perform multi-source adsorption on the leather, making the leather prone to displacement and deformation during the cutting process. Summary of the Invention

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In this invention, by setting up a tension pulling component, under the guidance of the guide groove and the deformation of the spring telescopic rod, the leather can automatically adjust its tension according to its own material properties during the pulling process. On the one hand, this 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, preventing loosening and wrinkles from affecting the cutting accuracy, thereby improving the accuracy and quality of laser cutting of automotive interior leather.

[0018] 2. In this invention, by setting up an up-and-down swinging mechanism, the tensioned leather is swung up and down under the combined action of the protruding plate, roller and spring, 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 amplitude can be adjusted according to the thickness and elasticity of the leather to adapt to the cutting requirements of different materials.

[0019] 3. In this invention, by setting up an adsorption positioning component, under the combined action of the piston rod and the hollow cylinder, the inside of several cylinders is in a negative pressure state. On the one hand, the leather is adsorbed to avoid cutting errors caused by slight displacement or shaking of the leather. At the same time, the non-contact adsorption method will not cause scratches or indentations on the leather surface, effectively protecting the surface quality of the leather. On the other hand, through multiple adsorption sources, the uncut parts can still be tightly attached to the alloy perforated plate, which can keep the leather stable during the cutting process, reduce leather displacement and deformation caused by the loss of local negative pressure, thereby improving cutting accuracy and quality.

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

[0032] In this embodiment, the four corners of the leather used for automotive interiors are placed at the four corners of the tension pulling component 5. The tension pulling component 5 then fixes the four corners of the leather and moves it backward. During the movement, the tension is automatically adjusted according to the material properties of the leather. Then, the adsorption positioning component 6 performs multi-source negative pressure adsorption on the lower end of the leather to position the leather. Finally, the laser cutting mechanism 4 cuts round holes in the leather.

[0033] The laser cutting mechanism 4 mentioned above is a mature laser cutting technology and equipment in the existing technology. In this solution, it is used to perform laser cutting operations by allowing free movement on the X, Y and Z axes. Its internal structure, principle and connection method will not be described further.

[0034] Specifically, to achieve adaptive tension adjustment of automotive leather, see [link / reference]. Figure 3 , Figure 4 , Figure 5 and Figure 6 In this embodiment, the tension pulling component 5 includes an electric cylinder 51 fixedly connected to the front of the inner surface of the outer shell 1, and an expansion mechanism 52 is provided on the inner surface of the base plate 7. The upper end of the expansion mechanism 52 is symmetrically provided with a clamping and fixing mechanism 53 and an up-and-down swinging mechanism 54.

[0035] For further details, please refer to [link / reference]. 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. The left ends of the two spring telescopic rods 531 are jointly fixedly connected to a concave plate 532. The upper end of the concave plate 532 is fixedly connected to an electric cylinder 533, and the lower end of the electric cylinder 533 is fixedly connected to a fixing plate 534 that is slidably connected to the concave plate 532.

[0036] For further details, please refer to [link / reference]. 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. A guide rod 522 is slidably connected to the outer surface of the push rod 521. Four annular holes 523 are opened on the inner surface of the guide rod 522. Guide grooves 524 are opened at the four corners of the upper end of the base plate 7. Annular blocks 525 are slidably connected to the inner surfaces of the four annular holes 523. Round rods 526 that are slidably connected to the guide grooves 524 are fixedly connected to the inner surfaces of the four annular blocks 525. A spring 527 is sleeved on the outer surface of the push rod 521. The two ends of the spring 527 are fixedly connected to the front end of the guide rod 522 and the round blocks on the push rod 521, respectively. Square rod blocks 528 are slidably connected to the inner surfaces of the four round rods 526.

[0037] During implementation, the four corners of the leather are placed one by one into the inner surface of the concave plate 532. Immediately after each corner is placed, the second electric cylinder 533 is activated to push the fixing plate 534 downwards until the fixing plate 534 secures the leather. After all four corners of the leather are secured, the first electric cylinder 51 is activated to push the push rod 521 backwards. Under the action of the first spring 527, the guide rod 522 moves backwards. Because the distance between the inner surfaces of the guide grooves 524 on both sides gradually increases from front to back, the two round rods 526, under the limiting action of the guide grooves 524, drive the annular block 525 to slide on the inner surface of the annular hole 523. When the round rods... When the 526 moves to the horizontal plane of the guide groove 524, the fixed leather on both sides is pulled. Through the deformation of the spring telescopic rod 531, the leather can automatically adjust its tension according to its own material properties during the pulling process. On the one hand, this can avoid damage to the leather, and on the other hand, it can keep the tension of the leather at a suitable level. This effectively prevents 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, preventing loosening and wrinkles from affecting the cutting accuracy. This improves the precision and quality of laser cutting of automotive interior leather and meets the fine and high-standard cutting requirements of automotive interiors.

[0038] For further details, please refer to [link / reference]. Figure 3 and Figure 6 In this embodiment, the up-and-down swing mechanism 54 includes a protruding plate 541 that is symmetrically and fixedly connected to the inner surface of the outer shell 1. Rollers 542 are fixedly connected to the lower ends of the four square rod blocks 528. Springs 543 are sleeved on the outer surfaces of the four square rod blocks 528. The two ends of the four springs 543 are fixedly connected to the upper ends of the rollers 542 and the round blocks on the outer surface of the round rods 526, respectively.

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

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

[0041] Example 2: Based on Example 1, this example adds an adsorption and positioning component 6 for multi-source adsorption and positioning of leather used in automotive interiors, thereby achieving the purpose of multi-source adsorption and positioning of leather used in automotive interiors.

[0042] Specifically, in order to achieve multi-source, zoned adsorption and positioning of leather used in automotive interiors, refer to... Figure 3 , Figure 7 , Figure 8 , Figure 9 and Figure 10 In this embodiment, the adsorption positioning component 6 includes a compression 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 base plate 7, a partitioning mechanism 63 is provided on the inner surface of the lifting mechanism 62, and an air extraction mechanism 64 is provided on the rear part of the inner surface of the outer shell 1.

[0043] For further details, please refer to [link / reference]. 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. A sliding frame 622 is slidably connected to the inner surface of the partition frame 621. A rubber strip 623 is fixedly connected to the upper end of the sliding frame 622. A hemispherical rod 624 slidably connected to the inner surface of the partition frame 621 is fixedly connected to the lower end of the sliding frame 622. A spring 625 is sleeved on the outer surface of the hemispherical rod 624. The two ends of the spring 625 are fixedly connected to the lower end of the partition frame 621 and the hemisphere on the hemispherical rod 624, respectively.

[0044] For further details, please refer to [link / reference]. Figure 3 and Figure 9 In this embodiment, the partitioning mechanism 63 includes a plurality of alloy round hole plates 631 fixedly connected to the inner surface of the sliding frame 622. The lower round holes of the plurality of alloy round hole plates 631 are all fixedly connected to cylinders 632. The inner surfaces of the plurality of cylinders 632 on the same side are all fixedly connected to a vent pipe 633. The upper end of the vent pipe 633 is located in the inner cavity of the cylinder 632 and is fixedly connected to a plurality of solenoid valves 634.

[0045] During implementation, when the round rod 526 moves to the rear 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 backward. At this time, the spring 527 will gradually be in a compressed state. During the backward movement of the push rod 521, it will push the inclined surface of the extrusion plate 61 to squeeze the hemisphere at the lower end of the hemisphere rod 624, so that the hemisphere rod 624 will gradually move upward and push the sliding frame 622 to slide on the inner surface of the partition frame 621, so that the rubber strip 623 and the alloy round hole plate 631 are tightly attached to the lower end of the leather.

[0046] For further details, please refer to [link / reference]. Figure 3 and Figure 10 In this embodiment, the air extraction mechanism 64 includes a connecting plate 641 fixedly connected to the rear part of the inner surface of the outer shell 1. Hollow cylinders 642 are symmetrically fixedly connected to the inner surface of the connecting plate 641. Piston rods 643 that are slidably connected to the connecting plate 641 are slidably connected to the inner surfaces of the two hollow cylinders 642. Springs 644 are sleeved on the outer surfaces of the two piston rods 643. The two ends of the two springs 644 are fixedly connected to the piston on the piston rod 643 and the lower part of the inner surface of the hollow cylinder 642, respectively. A connecting pipe 646 that is fixedly connected to the vent pipe 633 is fixedly connected to the upper part of the inner surface of the two hollow cylinders 642. A solenoid valve 647 is fixedly connected to the upper part of the inner surface of the two hollow cylinders 642.

[0047] For further details, please refer to [link / reference]. Figure 3 and Figure 10 In this embodiment, inclined plates 648 are fixedly connected to the upper ends of the two piston rods 643, and extrusion rods 645 are symmetrically fixedly connected to the left and right ends of the extrusion plate 61.

[0048] During implementation, after the rubber strip 623 and the alloy perforated plate 631 are tightly attached to the lower end of the leather, the push rod 521 is pushed backward. Simultaneously, the lower hemisphere of the hemispherical rod 624 moves to the horizontal position of the extrusion plate 61. The backward movement of the extrusion plate 61 drives the extrusion rod 645 backward, and during this movement, it extrudes the inclined surface on the inclined panel 648, causing the inclined panel 648 to push the piston rod 643 downward. At the same time, the piston rod 643 slides downward on the inner surface of the hollow cylinder 642, and the spring 644 is compressed. By using the combined action of the vent pipe 633, the connecting pipe 646, and the solenoid valve 634, air is drawn from inside the cylinder 632, creating a negative pressure state inside the cylinder 632. This allows the lower end of the leather to be tightly adsorbed onto the upper end of the alloy perforated plate 631, ensuring the leather maintains a stable position during subsequent laser cutting. This avoids cutting errors caused by minor displacement or vibration of the leather, effectively preventing burrs, unevenness, and incomplete cutting at the cutting edges. Furthermore, the non-contact adsorption method prevents scratches or indentations on the leather surface, effectively protecting the surface quality of the leather.

[0049] Secondly, during the laser cutting of circular holes in leather, the laser cuts one by one. When the leather position adsorbed at the upper end of a certain cylinder 632 is cut, this position will come into contact with the outside air, and at the same time, this position will no longer be in a negative pressure state. Through several cylinders 632, the uncut parts can still stick tightly to the upper end of the alloy circular hole plate 631. Through multiple adsorption sources, the uncut parts can still stick tightly 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, thereby improving the cutting accuracy and quality.

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

[0051] The rubber strip 623 mentioned above, in this solution, only needs to meet the requirements of high temperature resistance and a fire-retardant coating on the surface.

[0052] The solenoid valve 634 and solenoid valve 647 mentioned above are mature unidirectional control technologies and devices in the prior art. In this solution, they are used to control the direction of gas flow. Their internal structure, principle and connection method will not be described further.

[0053] Work process: During use, the leather is fixed by the cooperation between the clamping and fixing mechanism 53 and the expansion mechanism 52. After fixing, the tension is adaptively adjusted. Then, the up and down swinging mechanism 54 drives the leather to swing, so that the stress generated by the tension of the leather is evenly distributed. The lifting mechanism 62 is pressed tightly against the lower end of the leather. The partitioning mechanism 63 and the air extraction mechanism 64 perform partitioned multi-source adsorption and fixing operations on the lower end of the leather.

[0054] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
