Description

Technical Field

[0001] This invention relates to the field of intelligent laser cutting machine technology, specifically to an intelligent laser cutting machine for the production of automotive metal interior parts. Background Technology

[0002] Automotive metal interior parts (such as aluminum alloy trim strips, stainless steel panels, magnesium alloy brackets, etc.) have been increasing in proportion in automotive interior assembly due to their excellent texture, high strength, and high durability. These metal interior parts usually have the process requirements of thin walls (thickness 0.3-2.0mm), high precision dimensional tolerance (±0.05mm), and burr-free edges. Therefore, it is necessary to use automatic and semi-automatic electric arc, plasma arc and other metal cutting equipment to cut the metal materials with high precision. Intelligent laser cutting machine is the most common processing and cutting equipment for automotive metal interior parts.

[0003] The prior art (Chinese patent publication number: CN120190510A, publication date: 2025-06-24) discloses a laser cutting machine tool for vehicle interior trim, including a cutting table and a laser cutting head. The cutting table has a hollowed-out design in the middle and a drawer-type waste tray is movably inserted therein. A vacuum cleaner is fixedly installed at one end of the cutting table and an air pump is fixedly installed at the other end. Diverter seats are fixedly installed on both sides of the cutting table. Multiple dust suction holes are equally spaced on both inner side walls of the cutting table. Cavities for dust suction are also opened on both inner side walls of the cutting table. The output end of the vacuum cleaner is fixedly connected to two cavities in the cutting table. The machine also includes a device installed on the top of the cutting table. An adjustment assembly for adjusting the position of the laser cutting head, and multiple equidistant support groups mounted on the cutting table for placing vehicle interior panels; this laser cutting machine tool achieves the purpose of switching the air duct according to the rollers in the adjustment assembly to drive the opening and closing of the sealed windshield, and has excellent cleaning ability for the cut seam of the workpiece to be cut. Existing technology (Chinese patent publication number: CN218964398U, publication date: 2023-05-05) discloses a three-axis laser cutting device for automotive interior parts, including a worktable with an opening; a three-axis laser cutting machine placed in the opening; and a cover plate that can open or close the opening; to... And automotive trim fixture components, which are placed inside the opening and below the three-axis laser cutting machine, effectively reduce the diffusion of smoke and dust during processing through the opening and cover plate, reduce the harmfulness of irritating gases to the human body, and prevent the risk of laser beam burns. Existing technology (Chinese patent publication number: CN219484556U, publication date 2023-08-08) discloses a stainless steel plate adsorption platform for laser cutting equipment, relating to the field of laser cutting technology. This stainless steel plate adsorption platform for laser cutting equipment includes an open adsorption platform with several holes, through which... The negative pressure machine is fixed to the negative pressure machine carrier plate by bolts. The negative pressure machine carrier plate is rectangular and hollow inside. There are four circular holes on the bottom shell of the negative pressure machine carrier plate, and a negative pressure machine is installed in each of the four circular holes. The air outlet of the negative pressure machine is located at the bottom of the negative pressure machine. The negative pressure machine carrier plate is fixed on the I-shaped steel bracket. Traditional laser cutting machines require manual adjustment of the direction and cutting position of the plate during the cutting process. During the cutting process, some specific clamping tools are mostly needed to fix it. If the cut waste is not fixed, it is easy to shake and the high temperature can easily cause safety hazards.

[0004] Existing intelligent laser cutting machines used in the production of automotive metal interior parts are not suitable for efficient multi-position positioning of thin metal sheets during the cutting process. This causes the sheet to vibrate under the impact of the cutting protective gas, which in turn affects the cutting accuracy and produces a large number of burrs at the cutting position, increasing the burden of subsequent processing and exhibiting certain defects in use. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent laser cutting machine for the production of automotive metal interior parts, in order to solve the problem mentioned in the background art that current intelligent laser cutting machines on the market are inconvenient to perform efficient multi-position positioning of thin metal sheets during the cutting process, causing the sheet to vibrate under the impact of the cutting protective gas, which in turn affects the cutting accuracy.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an intelligent laser cutting machine for the production of automotive metal interior parts, comprising a machine body, an adjustment seat on the machine body, a laser cutting head mounted on the adjustment seat, and a collection component mounted on the machine body; an adsorption platform fixedly mounted on the machine body, with adsorption seats uniformly installed through the upper surface of the adsorption platform; a first cavity and a second cavity formed by a fixedly mounted partition plate on the inner side of the adsorption seat; a vacuum pump and an air pump respectively connected to the first cavity and the second cavity via external air pipes; a lifting seat elastically lifting and lowering mounted on the inner side of the adsorption seat, with a transmission component between the adsorption seat and the lifting seat; the lifting seat rotates synchronously during lifting and lowering driven by the transmission component; a through hole communicating with the second cavity is opened on the lifting seat; a purge pipe is also mounted on the lifting seat; and a downward positioning component is fixedly mounted on the upper outer side of the lifting seat near the material to be cut; a pressure regulating component is provided inside the first cavity for adjusting the air pressure inside the first cavity by controlling the cutting heat.

[0007] Preferably, the inner side of the adsorption seat is provided with an air cavity and an air hole, and the air hole is connected to the first cavity through the air cavity. When the upper port of the adsorption seat is connected to the air hole, the metal plate is adsorbed.

[0008] Preferably, the upper end of the lifting seat is higher than the upper end of the adsorption seat, and a connecting block is rotatably installed at the lower end of the lifting seat. A reset spring is connected between the connecting block and the partition plate. The lifting seat and the adsorption seat can be adjusted for extension and retraction under the gravity of the plate.

[0009] Preferably, the upper outer diameter of the lifting seat is smaller than its lower outer diameter, and the lower part of the lifting seat and the adsorption seat are in a sealed sliding connection. When the upper part of the lifting seat moves down into the inner side of the adsorption seat, the upper port of the adsorption seat is connected to the air hole.

[0010] Preferably, an air supply pipe is connected between the lifting seat and the second cavity, and the air supply pipe is connected to the through hole, and the through hole and the purge pipe are connected, and both the through hole and the purge pipe are equipped with a one-way valve.

[0011] Preferably, the transmission assembly includes ball bearings embedded in the inner wall of the adsorption seat, and a spiral guide groove is provided on the lower outer side of the lifting seat, with the ball bearings rolling along the guide groove. During the lifting process, the lifting seat is driven to rotate synchronously through the cooperation of the ball bearings and the guide groove.

[0012] Preferably, the port of the adsorption seat and the port of the through hole are both sealed and fitted to the surface of the plate to be cut, and after the lifting seat moves down, the inner wall of the adsorption seat fits and seals the purge pipe.

[0013] Preferably, the pressing positioning component includes a clamp fixedly installed on the outer side of the upper part of the lifting seat, and an elastic pressure plate with an arc-shaped structure is fixedly provided on the outer side of the clamp, and the elastic pressure plate is driven to fit and clamp the edge of the plate to be cut during the downward rotation of the lifting seat.

[0014] Preferably, a filter screen is provided on the inner side of the second cavity, a waste discharge port is provided at the lower end of the adsorption platform, and a sealing plate is rotatably connected to the lower end face of the adsorption platform, and the sealing plate seals and blocks the waste discharge port. An electric telescopic rod is hinged between the frame at the lower end of the adsorption platform and the sealing plate.

[0015] Preferably, the pressure regulating component includes a pressure regulating plate that is lifted and installed inside the adsorption stage, and a memory metal sheet is fixedly connected between the pressure regulating plate and the upper inner wall of the adsorption stage. The memory metal sheet bends when heated to pull the pressure regulating plate upward inside the adsorption stage.

[0016] Compared with the prior art, the beneficial effects of the present invention are: the intelligent laser cutting machine for the production of automotive metal interior parts can automatically position the sheet metal at multiple points and in multiple ways, avoiding the impact and vibration of the protective gas during the cutting of thin sheet metal, effectively improving the cutting effect, and can effectively treat the cutting fumes, as detailed below;

[0017] 1. It is equipped with an adsorption seat and a lifting seat. The lifting seat moves downward under the gravity of the board, so that the port of the adsorption seat is connected to the first cavity. This allows the adsorption table to automatically adjust the adsorption point according to the size of the board, ensuring the concentration of negative pressure force and achieving efficient and stable adsorption of the board.

[0018] 2. Equipped with a lifting seat, clamping seat, and elastic pressure plate, as the air pressure inside the first cavity decreases, the lifting seat located at the edge of the plate will move downward under the negative pressure inside the first cavity. This causes the clamping seat on the outer side of part of the lifting seat to move downward and rotate synchronously with the elastic pressure plate, thereby achieving downward pressure positioning of the edge of the plate. This, combined with the negative pressure adsorption effect, further improves the positioning stability of the plate and effectively ensures the laser cutting accuracy.

[0019] 3. Equipped with a lifting seat, through holes, and a purge pipe, the second chamber, connected to an air pump, can extract cutting fumes and dust generated in the working area through the through holes. Simultaneously, the lifting seat below the plate can assist in adsorption of the plate through the through holes, and the filter screen can filter the fumes. Afterward, easy cleaning can be achieved by opening the sealing plate. When cutting is completed, when air is supplied to the second chamber by the air pump, the gas can be blown out through the purge pipe. At the same time, in conjunction with the rising and rotating of the lifting seat, the waste on the surface of the adsorption table can be blown and cleaned, and collected by the collection component.

[0020] 4. It is equipped with a pressure regulating plate and a memory metal sheet. The pressure regulating plate can conduct heat to the memory metal sheet during the cutting process, causing the memory metal sheet to bend due to temperature. This applies an upward pulling force to the pressure regulating plate, thereby regulating the air pressure inside the first cavity. This prevents the temperature at the adsorption seat port from rising, which would reduce the adsorption force and further improve the adsorption stability. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Most existing intelligent laser cutting machines used in the production of automotive metal interior parts have a simple positioning structure, which cannot effectively position thin metal sheets. This makes the sheet material prone to vibration under airflow, thus affecting cutting accuracy. To solve this technical problem, the following technical content is disclosed. Please refer to [link / reference]. Figures 1-8 As shown; an intelligent laser cutting machine for producing automotive metal interior parts includes a body 1, an adjustment seat 2 on the body 1, a laser cutting head 3 mounted on the adjustment seat 2, a collection component 4 mounted on the body 1, an adsorption platform 5 fixedly mounted on the body 1, and adsorption seats 6 uniformly installed through the upper surface of the adsorption platform 5. The inner side of the adsorption seat 6 is divided into a first cavity 8 and a second cavity 9 by a fixedly mounted partition plate 7. The first cavity 8 and the second cavity 9 are respectively connected to a vacuum pump and an air pump through an external air pipe 10. A lifting seat 11 is elastically lifted and lowered on the inner side of the adsorption seat 6, and a transmission component is provided between the adsorption seat 6 and the lifting seat 11. The lifting seat 11 is driven to rotate synchronously during the lifting and lowering process by the transmission component. At the same time, the lifting seat 11 has a through hole 17 communicating with the second cavity 9, and a blow pipe 18 is also installed on the lifting seat 11. A pressing positioning component is fixedly installed on the upper outer side of the lifting seat 11 near the material to be cut.

[0034] An air chamber 601 and an air hole 602 are provided on the inner side of the adsorption seat 6. The air hole 602 is connected to the first cavity 8 through the air chamber 601. When the upper port of the adsorption seat 6 is connected to the air hole 602, the metal plate is adsorbed. The upper end of the lifting seat 11 is higher than the upper end of the adsorption seat 6. A connecting block is rotatably installed at the lower end of the lifting seat 11. A return spring 12 is connected between the connecting block and the partition plate 7. The lifting seat 11 and the adsorption seat 6 are telescopically adjusted under the weight of the plate. The outer diameter of the upper part of the lifting seat 11 is smaller than its outer diameter at the lower part. The lower part of the lifting seat 11 and the adsorption seat 6 are in a sealed sliding connection. When the upper part of the lifting seat 11 moves down into the inner side of the adsorption seat 6, the upper port of the adsorption seat 6 is connected to the air hole 602. The transmission component includes a ball bearing 603 embedded in the inner wall of the adsorption seat 6. The lower outer side of the lifting seat 11 is provided with a spiral guide groove 13, and the ball bearing 603 rolls along the guide groove 13. During the lifting process, the lifting seat 11 is driven to rotate synchronously by the cooperation of the ball bearing 603 and the guide groove 13. The pressing positioning component includes a clamp 14 fixedly installed on the upper outer side of the lifting seat 11. An elastic pressure plate 15 with an arc structure is fixedly provided on the outer side of the clamp 14. During the downward rotation of the lifting seat 11, the elastic pressure plate 15 is driven to fit and clamp the edge of the plate to be cut. A filter screen 19 is provided on the inner side of the second cavity 9. A waste discharge port is provided at the lower end of the adsorption table 5. A sealing plate 20 is rotatably connected to the lower end face of the adsorption table 5. The sealing plate 20 seals and blocks the waste discharge port. An electric telescopic rod 21 is hinged between the frame at the lower end of the adsorption table 5 and the sealing plate 20.

[0035] During cutting, the plate to be processed is placed above the adsorption table 5, causing the corresponding lifting seat 11 to move downwards under the weight of the plate. Since the upper outer diameter of the lifting seat 11 is smaller than the inner diameter of the port of the adsorption seat 6, the port of the adsorption seat 6 is connected to the first cavity 8 through the air chamber 601 and the air hole 602. This allows the adsorption table 5 to automatically adjust the adsorption point according to the size of the plate, ensuring concentrated negative pressure and achieving efficient and stable adsorption of the plate. Subsequently, the vacuum pump connected to the outside of the first cavity 8 is activated, allowing the port of the adsorption seat 6 to adsorb the plate. As the negative pressure increases, the lifting seats 11 in other positions will move downward under the negative pressure inside the first cavity 8. By controlling the vacuum pump, the ports of the adsorption seats 6 in other positions are prevented from opening. At this time, the lifting seats 11 located at the edge of the plate will move downward under the negative pressure inside the first cavity 8, so that the clamps 14 pre-installed on the outer side of some lifting seats 11 drive the elastic pressure plates 15 to move downward and rotate synchronously, thereby realizing the downward positioning of the edge of the plate. Combined with the negative pressure adsorption effect, the positioning stability of the plate is further improved, effectively ensuring the laser cutting accuracy.

[0036] like Figures 9-10As shown, a pressure regulating component is provided inside the first cavity 8, which is controlled and adjusted by the heat of cutting. The pressure regulating component adjusts the air pressure inside the first cavity 8. The pressure regulating component includes a pressure regulating plate 22 that is lifted and installed inside the adsorption stage 5. A memory metal sheet 23 is fixedly connected between the pressure regulating plate 22 and the upper inner wall of the adsorption stage 5. The memory metal sheet 23 bends after being heated to pull the pressure regulating plate 22 to move upward inside the adsorption stage 5.

[0037] The pressure regulating plate 22 can be made of a thermally conductive material and is slidably connected to the inner wall of the adsorption table 5. It can conduct heat to the shape memory metal sheet 23 during the cutting process, causing the shape memory metal sheet 23 to bend under the influence of temperature, thereby applying an upward pulling force to the pressure regulating plate 22, and thus regulating the air pressure inside the first cavity 8. This prevents the temperature at the port of the adsorption seat 6 from rising, which would reduce the adsorption force and further improve the adsorption stability. The shape memory metal sheet 23 can be made of nickel-titanium alloy.

[0038] like Figures 5-8 As shown, an air supply pipe 16 is connected between the lifting seat 11 and the second cavity 9, and the air supply pipe 16 is connected to the through hole 17. The through hole 17 and the purge pipe 18 are also connected. Both the through hole 17 and the purge pipe 18 are equipped with one-way valves. The port of the adsorption seat 6 and the port of the through hole 17 are sealed and fitted to the surface of the plate to be cut. After the lifting seat 11 moves down, the inner wall of the adsorption seat 6 fits and seals the purge pipe 18.

[0039] During the cutting process, the air pump connected to the outside of the second chamber 9 is started simultaneously. As the air pump works, the second chamber 9 can extract the cutting fumes and dust generated in the working area through the through hole 17. At the same time, the lifting seat 11 under the plate can assist in adsorption of the plate through the through hole 17 to achieve secondary adsorption. The filter screen 19 can filter the fumes. In the non-cutting state, the sealing plate 20 can be rotated and opened by controlling the electric telescopic rod 21 to achieve convenient cleaning. When the cutting is completed, when the air pump supplies air to the second chamber 9, the gas can be blown out through the blow pipe 18. At the same time, the air pressure inside the first chamber 8 is gradually restored, so that the lifting seat 11 under the non-plate moves up and rotates under the elastic force of the return spring 12. The blow pipe 18 can blow and clean the waste on the surface of the adsorption table 5 and collect it through the collection part 4.

[0040] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0041] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
