Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting machine tools, and particularly to a laser cutting machine tool for vehicle interiors. Background Art

[0002] Laser cutting is a high-precision, high-speed, and harmless material cutting technology. It realizes operations such as cutting, engraving, and marking of materials through the action of a laser beam. Laser cutting technology is widely used in fields such as medical devices, aerospace, automobiles, electronics, packaging, and construction. The principle of laser cutting is that the laser beam is emitted from the laser head to the surface of the material. The material is subjected to the thermal effect and optical effect of the laser, and finally, the material undergoes changes such as cutting, engraving, and marking. During the processing of vehicle interiors, laser cutting is performed on some trim panels and trim strips. A large amount of dust is generated during the cutting process. In order not to pollute the production environment, it is necessary to perform dust removal treatment on this dust.

[0003] For example, the Chinese invention patent with the publication number CN116213956A discloses a laser cutting machine tool with stable long-slide cutting, including a large needle bed, a small needle bed, and a gantry support installed on the machine tool base. The small needle bed is stacked on the large needle bed, and a first screw mechanism is arranged on the top of the gantry support. A cutting device is installed on the first screw mechanism; taking the long side direction of the large needle bed as the Y-axis, the short side direction of the large needle bed as the X-axis, and the vertical direction as the Z-axis; the gantry support reciprocates along the Y-axis direction, and the cutting device reciprocates along the X-axis direction through the first screw mechanism; the cutting device includes a cutting head, and the cutting head is movably connected to one XZ side of the first screw mechanism through a fastening device, and the cutting head reciprocates along the Z-axis direction. The present invention realizes the cutting of parts in different thickness states through a long slide, and strengthens the stability of the cutting head in the Y-axis direction through a fastening device, without the need to add a lifting auxiliary tooling, which helps to improve the operation efficiency of the machine tool and helps to improve the cutting accuracy of the machine tool.

[0004] For example, the Chinese invention patent with the publication number CN114559169B discloses a laser cutting machine tool with a self-cleaning function, including a laser cutting machine tool body. A moving structure for adjusting the cutting position is arranged on the laser cutting machine tool body. A laser cutting structure for cutting a substrate is arranged on the moving structure. A cleaning structure for taking a workpiece finished product is arranged on the laser cutting structure. A storage structure for storing the workpiece finished product is arranged on the cleaning structure; a driving structure is arranged on the laser cutting machine tool body. The driving structure drives the feeding structure to be slidably connected with the laser cutting machine tool body. A supporting structure corresponding to the feeding structure is arranged on the laser cutting machine tool body; after placing a substrate on the feeding structure, the driving structure drives the feeding structure to move, so that the feeding structure drives the substrate to be stably placed on the supporting structure, making the feeding of the substrate more convenient and fast. The cleaning structure is driven by the laser cutting structure, so that the cleaning structure drives the storage structure to receive the finished workpiece at the bottom.

[0005] Traditional laser cutting machines mostly adopt the design of constant suction through the lower air inlet. The above two comparative documents have a common drawback. When the size of the vehicle interior parts is small while the width (span) of the cutting machine is large, it is easy to cause weak suction at the middle position of the machine tool, affecting the dust collection effect. At the same time, during the cutting process of relatively thick vehicle interior parts, debris and soot are likely to remain in the cut. Summary of the Invention

[0006] The purpose of the present invention is to solve the drawbacks of the traditional laser cutting machines in the prior art, which mostly adopt the design of constant suction through the lower air inlet.

At the same time, during the cutting process of relatively thick vehicle interior parts, debris and soot are likely to remain in the cut.

[0007] To achieve the above purpose, the present invention adopts the following technical solutions: A laser cutting machine for vehicle interiors includes a cutting table and a laser cutting head. The middle part of the cutting table is designed to be hollow and is movably inserted with a drawer-type waste tray. One end of the cutting table is fixedly installed with a vacuum cleaner and the other end is fixedly installed with a blower pump. Both sides of the cutting table are fixedly installed with flow distribution seats. The output end of the blower pump is fixedly communicated with the flow distribution seats. A plurality of dust suction holes are equidistantly opened on both inner walls of the cutting table, and cavities for dust suction are opened on both inner walls of the cutting table. The output ends of the vacuum cleaner are respectively fixedly communicated with the two cavities inside the cutting table. It further includes: An adjustment component installed on the top of the cutting table for adjusting the position of the laser cutting head; A plurality of support components installed equidistantly on the cutting table for placing vehicle interior panels.

[0008] In at least some embodiments, the adjustment component includes a first lead screw drive, a second lead screw drive, and a third lead screw drive. There are two first lead screw drives, which are symmetrically and fixedly installed on both sides of the top of the cutting table respectively. There are two second lead screw drives, which are respectively fixedly installed on the lead screw pairs of the two first lead screw drives. The bottom of the lead screw pair of the first lead screw drive is fixedly installed with a mounting plate. The tops of the lead screw pairs of the two second lead screw drives are both fixedly installed with a gantry. The third lead screw drive is fixedly installed on the tops of the two gantries.

[0009] In at least some embodiments, a fixing rod is fixedly installed at the bottom of the mounting plate. Notches are correspondingly opened on the top of the cutting table and at the bottoms of the two first lead screw drives. The fixing rod passes through the notch and extends into the cavity inside the cutting table, and a roller is fixedly installed at the bottom of the fixing rod.

[0010] In at least some embodiments, the dust suction hole and the sealing windshield are both circular, the diameter of the sealing windshield is larger than the diameter of the dust suction hole, and the bottom of the roller and the top of the sealing windshield are on the same horizontal line.

[0011] In at least some embodiments, two of the second lead screw drivers are fixedly mounted with infrared light curtain plates at one end close to each other, a visual sensor is fixedly mounted on the laser cutting head, and the infrared light curtain plate and the visual sensor are electrically connected to an external control terminal.

[0012] In at least some embodiments, the supporting assembly includes a placement plate, an air pipe and a sealing windshield, wherein shaft tubes are fixedly welded on both sides of the placement plate, and the placement plate is rotatably installed in the cutting table through the shaft tubes, and torsion springs are fixedly installed between both ends of the shaft tube and the inner wall of the cutting table, the air pipe is rotatably inserted in the two shaft tubes, and both ends of the air pipe are fixedly connected to the diverter seats on both sides of the cutting table, and a connecting rod is integrally formed on the sealing windshield, and the connecting rod is fixedly mounted on the shaft tube.

[0013] In at least some embodiments, a plurality of blowing holes are provided on the air pipe, and the plurality of blowing holes are provided obliquely and distributed on both sides of the air pipe, and the blowing holes are provided at a 90-degree angle to the placement plate.

The first screw driver drives the second screw driver to slide, so as to drive the roller in the adjustment assembly to move in the horizontal direction of the placement plate, and the placement plate under the vehicle interior component to be cut is rotated and opened, and then the sealed windshield is driven to rotate so that the dust suction hole is connected with the outside, so as to achieve the purpose of follow-up air duct switching. Compared with the traditional normally open wind tunnel, the wind tunnel has stronger suction and better dust suction effect. During the dust suction process, the air pump is used to blow air to the oblique air holes on the air pipe, and the diverter seat adjusts the corresponding air pipe to open and close, so as to blow away the debris and smoke remaining in the cut seam of the vehicle interior component, so as to achieve the purpose of cleaning.

[0016] 2. The roller in the adjustment assembly moves in the opposite direction of the placement plate, driving the placement plates to rotate in the opposite direction one by one (the placement plates rotate toward the top of the cutting table), pushing the vehicle interior parts to gradually move after cutting, thereby achieving the purpose of transmission and unloading.

Detailed Embodiment

[0019] In order to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the limitations of the specific embodiments disclosed in the following specification.

[0021] Embodiment, according to Figures 1-8 , a laser cutting machine tool for vehicle interiors provided by an embodiment of the present invention includes a cutting table 1 and a laser cutting head 2, as Figure 1And Figure 2 As shown, in the middle of the cutting table 1 is a hollow design and a drawer-type waste tray 101 is movably inserted. The waste generated during the cutting process of vehicle interior parts will directly fall into the drawer-type waste tray 101 for collection. One end of the cutting table 1 is fixedly installed with a vacuum cleaner 102 and the other end is fixedly installed with a blower pump 103. Both sides of the cutting table 1 are fixedly installed with flow splitting seats 104. The output end of the blower pump 103 is fixedly communicated with the flow splitting seats 104. A plurality of dust suction holes 105 are equidistantly arranged on both inner walls of the cutting table 1. Cavities for dust suction are arranged on both inner walls of the cutting table 1. The output ends of the vacuum cleaner 102 are respectively fixedly communicated with the two cavities in the cutting table 1. During use, the vacuum cleaner 102 starts to suck air, sucks air into the cavities in the cutting table 1 through a connecting pipe, and then sucks the dust generated during the cutting process of vehicle interior parts through the dust suction holes 105. The vacuum cleaner 102 can be connected to an external filter to achieve the purpose of purifying the air in the working environment. It further includes: An adjusting assembly 3 installed on the top of the cutting table 1 for adjusting the position of the laser cutting head 2; A plurality of supporting assemblies 4 installed equidistantly on the cutting table 1 for placing vehicle interior panels.

[0022] As Figures 1-3As shown in the figure, the adjustment assembly 3 includes a first lead screw driver 301, a second lead screw driver 302, and a third lead screw driver 303. There are two first lead screw drivers 301, which are symmetrically and fixedly installed on both sides of the top of the cutting table 1 respectively. There are two second lead screw drivers 302, which are respectively fixedly installed on the lead screw pairs of the two first lead screw drivers 301. A mounting plate 304 is fixedly installed at the bottom of the lead screw pair of the first lead screw driver 301. The tops of the lead screw pairs of the two second lead screw drivers 302 are both fixedly installed with gantry frames 308. The third lead screw driver 303 is fixedly installed on the tops of the two gantry frames 308. A lifting seat is fixedly installed on the lead screw pair of the third lead screw driver 303. The laser cutting head 2 is fixedly installed on the lifting seat. During use, the first lead screw driver 301 is used to drive the second lead screw driver 302 to slide to adjust the horizontal lateral position of the laser cutting head 2 before cutting. And during the movement of the second lead screw driver 302, it will trigger the rotation and opening of the supporting assembly 4. The second lead screw driver 302 is used to drive the gantry frame 308 to move to adjust the horizontal lateral position of the laser cutting head 2 during the cutting process. The third lead screw driver 303 is used to drive the lifting seat to move to achieve the purpose of adjusting the horizontal longitudinal position of the laser cutting head 2. The lifting of the lifting seat drives the lifting of the laser cutting head 2 to achieve the purpose of adjusting the vertical position of the laser cutting head 2, so as to achieve the purpose of multi-directional cutting. It should be noted that this technical solution adopts the design of superimposing the second lead screw driver 302 and the first lead screw driver 301. The movement of the lead screw pair in the first lead screw driver 301 accurately triggers the rotation of the corresponding supporting assembly 4 under the vehicle interior trim panel to be cut. Then, the movement of the lead screw pair in the second lead screw driver 302 is used to adjust the horizontal lateral position of the laser cutting head 2 to prevent the unstable triggering of the supporting assembly 4 caused by the movement of the laser cutting head 2 during the cutting process.

[0023] As Figure 3 shown, infrared light curtain plates 307 are fixedly installed at the mutually approaching ends of the two second lead screw drivers 302. A visual sensor 201 is fixedly installed on the laser cutting head 2. Both the infrared light curtain plate 307 and the visual sensor 201 are electrically connected to an external control terminal. During use, the infrared light curtain plate 307 reflects infrared rays to detect the width of the component to be cut, ensuring that the position where the second lead screw driver 302 stops can accurately trigger the corresponding supporting assembly 4. The visual sensor 201 is used to detect the size and cutting condition of the vehicle interior trim part to be cut.

[0024] As Figures 4-6 shown, a fixing rod 305 is fixedly installed at the bottom of the mounting plate 304. Corresponding notches are respectively opened at the top of the cutting table 1 and the bottoms of the two first lead screw drivers 301. The fixing rod 305 passes through the notch and extends into the cavity inside the cutting table 1. A roller 306 is fixedly installed at the bottom of the fixing rod 305. As Figure 4As shown, a plurality of fixing holes for installing the fixing rod 305 are formed in the mounting plate 304. According to the width of the processed vehicle interior parts, the mounting rod is installed in different fixing holes to adjust the relative position of the roller 306 and the second lead screw driver 302, so as to be used for vehicle interior parts with different widths. Both the dust suction hole 105 and the sealing windshield 403 are circular, and the diameter of the sealing windshield 403 is larger than that of the dust suction hole 105. The bottom of the roller 306 and the top of the sealing windshield 403 are on the same horizontal line. During use, when the first lead screw driver 301 drives the second lead screw driver 302 to move, it drives the fixing rod 305 to slide along the notch, and drives the roller 306 to translate in the cavity of the cutting table 1. During the translation of the roller 306, the supporting assembly 4 will be triggered in sequence. It should be noted that the end of the fixing rod 305 is designed with the roller 306 to reduce the resistance during the movement of the moving rod.

[0025] As Figures 7-8As shown in the figure, the supporting component 4 includes a placement plate 401, an air pipe 402, and a sealing windshield 403. Shaft tubes 404 are fixedly welded to both sides of the placement plate 401. The placement plate 401 is rotatably installed in the cutting table 1 through the shaft tubes 404. Torsion springs 405 are fixedly installed between both ends of the shaft tubes 404 and the inner wall of the cutting table 1. The air pipe 402 is rotatably inserted into the two shaft tubes 404. Both ends of the air pipe 402 are fixedly communicated with the flow dividing seats 104 on both sides of the cutting table 1. A connecting rod 406 is integrally formed on the sealing windshield 403. The connecting rod 406 is fixedly sleeved on the shaft tube 404. A plurality of air blowing holes 407 are formed in the air pipe 402. The plurality of air blowing holes 407 are obliquely formed and distributed on both sides of the air pipe 402. The air blowing holes 407 are arranged at a right angle to the placement plate 401. The air pipe 402 is located directly above the dust suction holes 105, and the center of the dust suction holes 105 and the center of the air pipe 402 are on the same vertical line. The distance between adjacent two dust suction holes 105 is greater than the radius of the dust suction holes 105. During use, when the roller 306 in the adjusting component 3 moves in one direction (the direction in which the placement plate 401 is horizontally oriented), it will press the fixed rod 305 to rotate. The rotation of the fixed rod 305 drives the sealing windshield 403 to rotate, and the rotation of the sealing windshield 403 opens the dust suction holes 105. At the same time, the placement plate 401 under the vehicle interior part to be cut rotates downward and opens, so as to achieve the purpose of following the air duct switching. After cutting, the elastic force of the torsion spring 405 is used to make the sealing windshield 403 return to its original position so that the dust suction holes 105 are closed. When the roller 306 in the adjusting component 3 moves in the other direction (the opposite direction of the horizontal orientation of the placement plate 401), it drives the placement plate 401 to rotate in the reverse direction one by one (the placement plate 401 rotates upward towards the cutting table 1) and pushes the vehicle interior part to translate for discharging. It should be noted that the overall temperature of the vehicle interior part is relatively high just after cutting, and manual assistance with other equipment is required for discharging, which affects the processing efficiency. At the same time, since the placement plate 401 rotates by 90 degrees, the air blowing holes 407 on the air pipe 402 are also exposed and face the vehicle interior part. The air blowing pump 103 blows air into the obliquely arranged air holes on the air pipe 402 through the connecting pipe. The blown air blows away the debris and dust remaining in the cutting seams of the vehicle interior part. The dust is sucked away by the dust collector 102, and the debris falls into the waste collection tray for collection due to its weight. And by combining the data of the above-mentioned visual sensor 201, the positions of the holes and grooves on the vehicle interior part are identified, and the opening and closing of the corresponding air pipe 402 and the air pressure are adjusted through the flow dividing seat 104 to achieve the purpose of precise cleaning.

[0026] For the specific working principle, place the vehicle interior part on the cutting table 1, and make both ends of the vehicle interior part located on two air pipes 402 respectively. Before cutting, drive the second lead screw driver 302 to slide through the first lead screw driver 301, detect the position of the vehicle interior part through the infrared light curtain board 307, and place the vehicle interior part in the middle section of the second lead screw driver 302. When the roller 306 in the adjusting assembly 3 moves in one direction, it presses the fixed rod 305 to rotate. The rotation of the fixed rod 305 drives the sealing windshield 403 to rotate, and the suction holes 105 of the sealing windshield 403 are opened. At the same time, the placement plate 401 under the vehicle interior part to be cut rotates and opens, so as to achieve the purpose of follow-up air duct switching.

[0027] During the cutting process, drive the gantry 308 to move through the second lead screw driver 302 to adjust the horizontal lateral position of the laser cutting head 2 during the cutting process. Drive the lifting seat to move through the third lead screw driver 303 to achieve the purpose of adjusting the horizontal longitudinal position of the laser cutting head 2. Drive the laser cutting head 2 to lift and lower through the lifting and lowering of the lifting seat to achieve the purpose of adjusting the vertical position of the laser cutting head 2 for multi-directional cutting. The waste generated during cutting falls into the drawer-type waste tray 101 for collection. At the same time, the suction holes 105 are opened, and the vacuum cleaner 102 starts to inhale air, and sucks the dust generated during the cutting of the vehicle interior part through the cavity and the suction holes 105 to achieve the purpose of cleaning. And when the roller 306 in the adjusting assembly 3 moves in the other direction, it drives the placement plate 401 to rotate reversely one by one (the placement plate 401 rotates upward towards the cutting table 1) for discharging. At the same time, the air blower 103 blows air into the inclined air holes on the air pipe 402, and adjusts the opening and closing of the corresponding air pipe 402 through the flow dividing seat 104, so as to blow away the debris and dust remaining in the cut seam of the vehicle interior part after cutting, and then be sucked in through the suction holes 105 to achieve the purpose of cleaning.

[0028] The above is only the preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
