Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of laser cutting, in particular to an intelligent laser cutting device and method based on sheet metal production. BACKGROUND

[0002] The intelligent laser cutting device is the core equipment for realizing efficient and precise machining in modern manufacturing industry. It integrates high-power lasers, intelligent control systems, AI visual recognition and automatic feeding and discharging systems, and realizes the melting, vaporization or ablation of materials through the interaction between high-energy density laser beams and materials, and blows away the molten materials with high-speed airflow to complete the cutting.

[0003] Among them, since sheet metal parts are usually processed from flat materials, the raw materials can be divided into the basic profile required by design through cutting to facilitate subsequent reprocessing. Laser cutting device is usually used for cutting in this process.

[0004] Referring to the patent application with the publication number CN223146284U, a positioning device for sheet metal laser cutting is disclosed. The device is supported by multiple support bars. The bidirectional screw is rotated by starting the motor, causing the two positioning plates to move closer to each other. When the positioning plates move, they will push the rotating rod to rotate. The rotating rod rotates around the fixed shaft and rotates into the groove of the sliding bar. When the positioning plates move away from the rotating rod, the positioning plates clamp the sheet metal on both sides and position it left and right. The electric push rod is started to push the sliding bar, which moves along the sliding groove to the sheet metal. The multiple rotating rods push the sheet metal backward to the fixed plate to position the front and back of the sheet metal. The device automatically adjusts the positioning, is easy to operate, improves the positioning efficiency, reduces the positioning cost, and facilitates the positioning of the sheet metal.

[0005] The above-mentioned sheet metal laser cutting device in the prior art has the following defects in actual use:

[0006] 1) During the laser cutting of sheet metal, the sheet metal slag will fall on the support bars and the cutting table under the action of gravity. After cooling and solidification, a shell-shaped impurity will accumulate in the support bar tooth gap. The accumulation of slag will change the actual height of the support teeth, causing the focal length deviation between the workpiece and the laser cutting head, resulting in cutting seam width fluctuation or cutting not transparent, affecting the workpiece size accuracy. Manual cleaning of slag requires shutdown operation, thereby increasing the workpiece batch processing cycle;

[0007] 2) The residual energy of the laser in the above-mentioned patent frequently acts on the surface of the support bar, which easily causes the temperature of the support bar to rise sharply, easily causes the support bar to deform at high temperature, and causes the support bar top to have uneven support surface, thereby failing to form stable support for the workpiece.

[0008] Therefore, the present application proposes an intelligent laser cutting device and method based on sheet metal production to solve the above-mentioned problems. SUMMARY

[0009] In view of the deficiencies of the prior art, the present application provides an intelligent laser cutting device and method based on sheet metal production, which solves the problem that when laser cutting sheet metal, the sheet metal slag falls to the support bar and the cutting table under the action of gravity, and after cooling, the shell-shaped impurities accumulate in the tooth gap, changing the actual height of the support tooth, causing focal length deviation, triggering the cutting seam width fluctuation or cutting not transparent, affecting the dimensional accuracy, and manual cleaning needs to be stopped for operation, prolonging the processing cycle; and the long-time action of the residual energy of the laser causes the temperature of the support bar to rise sharply, which is easy to deform at high temperature, thereby causing the top support surface to be uneven and unable to smoothly support the workpiece.

[0010] To achieve the above object, the present application is realized by the following technical scheme: an intelligent laser cutting device based on sheet metal production, comprising a cutting table, further comprising:

[0013] Two transmission assemblies are arranged on both sides of the interior of the transmission chamber for power transmission between the chip removal assembly, the lifting assembly and the blowing assembly;

[0014] A slag outlet is opened on one side of the outer wall of the cutting table to provide a channel for the slag discharge in the plurality of support mechanisms.

[0015] Further, a mounting through slot is opened on the top of the bearing box, and a plurality of cleaning grooves are uniformly opened on the inner walls of both sides of the mounting through slot.

[0016] Furthermore, the chip removal assembly includes multiple waste residue collection ports located on the top of the support box and directly above the dust collection chamber. Wedge-shaped plates are fixedly installed on the top of the support box and on both sides of each waste residue collection port. A first movable through groove is provided on the inner wall of the dust collection chamber. A baffle is slidably installed inside the first movable through groove. Multiple docking through grooves are evenly provided on the top of the baffle. The multiple docking through grooves and multiple waste residue collection ports are staggered. A vertical rod is also fixedly installed on the side wall of the baffle. Guide rods are fixedly installed on both sides of the outer wall of the vertical rod. Springs are slidably sleeved on the outer wall of the guide rod. A second movable through groove for the movement of the vertical rod is provided on the outer wall of the dust collection chamber.

[0017] Furthermore, a slag output unit is provided inside the dust collection chamber and directly below the baffle. The slag output unit includes a second gear rotatably disposed on both sides of the inner wall of the dust collection chamber. Two second toothed belts are sleeved on the outer walls of the two second gears. Multiple scrapers are uniformly fixed on the outer walls of the two second toothed belts. A connecting shaft is also fixedly disposed at one end of the second gear. The connecting shaft rotatably passes through the bearing box and is fixedly disposed on a disc. Multiple protrusions for driving the vertical rod to move are uniformly fixed on the outer wall of the disc.

[0018] Furthermore, when the vertical rod is pushed by the protrusion to move, the multiple connecting slots and waste collection ports on the baffle can change from an interleaved state to an overlapping state, and the second gear is driven by a servo motor.

[0019] Furthermore, the lifting assembly includes a roller shaft, on the outer wall of which a plurality of supporting cones are uniformly fixed. Both ends of the roller shaft rotatably pass through the bearing box and are fixedly provided with a first gear. A first toothed belt is sleeved on the outer wall of the first gear.

[0020] Furthermore, the purging assembly includes an exhaust assembly and an air supply assembly. The air supply assembly is located below the exhaust assembly. The exhaust assembly includes a sealing plate fixedly disposed inside the transmission chamber and an exhaust channel opened on the top side of the sealing plate. A slag discharge nozzle connected to the exhaust channel is fixedly disposed at the bottom of the sealing plate. A lower air nozzle is fixedly disposed on the top side of the sealing plate.

[0023] This invention also discloses an intelligent laser cutting method based on sheet metal production, and an intelligent laser cutting device for sheet metal production. The method includes the following steps:

[0024] Step 1: Multiple lifting components lift the sheet metal to be cut together. After the laser cutting head finishes the sheet metal cutting operation, the lifting components rotate at a preset angle, and the slag adhering to the surface of the lifting components is scraped off and accumulates on the top of the carrier box.

[0025] Step 2: While the lifting component is rotating, the blowing component is driven by power and outputs airflow in a short time. The airflow blows the molten slag at the top of the transmission chamber toward the top of the dust collection chamber.

[0026] Step 3: The chip removal component collects the molten slag blown by the blowing component and collects it inside the dust collection chamber. When the lifting component rotates to switch the support surface, it pushes the molten slag inside the dust collection chamber toward the molten slag outlet.

[0027] This invention provides an intelligent laser cutting device and method for sheet metal production. Compared with the prior art, it has the following advantages:

[0028] 1. An intelligent laser cutting device and method for sheet metal parts production, which uses a servo motor to drive a scraper to intermittently scrape in the dust collection chamber. Combined with the design of a ramp and wedge plate, the molten slag is guided to slide naturally into the dust collection chamber, so that the molten slag automatically slides to the molten slag outlet, realizing continuous chip removal without human intervention, greatly reducing downtime for cleaning. In addition, the baffle is driven by a protrusion, which opens the docking slot only when chip removal is performed, and closes the waste slag collection port at other times, avoiding the problems of molten slag backflow and sheet metal parts falling and difficult to pick up, thereby ensuring that the chip removal channel is always unobstructed.

[0029] 2. An intelligent laser cutting device and method based on sheet metal production, through the rotational switching design of four supporting cones on the same cross-section of the supporting component, always keeps at least one cone vertically upward to support the sheet metal part. When switching the support surface, the cleaning groove can automatically scrape off the slag on the surface of the supporting cone, keeping the support surface clean and ensuring that the support surface remains flat. This avoids the problem of slag accumulation causing the end face formed at the top of the supporting cone to be unable to form a flat plane, thus ensuring that the supporting cone always maintains stable support for the sheet metal and guarantees cutting accuracy. Secondly, the four supporting cones on the same cross-section work alternately, allowing the replaced supporting cone to have sufficient time to cool down, reducing the risk of deformation and improving cutting stability.

[0030] 3. An intelligent laser cutting device and method based on sheet metal production, wherein the blowing assembly generates a high-speed airflow by squeezing the bellows-type airbag through a cam, which simultaneously cools the support cone on the surface of the lifting assembly and the molten slag on the top of the blowing transmission chamber, laying the foundation for subsequent molten slag collection, while preventing structural deformation or lifespan reduction caused by high temperature. Moreover, the relatively closed space formed by the sealing plate and the transmission chamber allows the airflow to concentrate on blowing away the replaced support cone to further blow away residual molten slag particles.

[0031] 4. An intelligent laser cutting device and method based on sheet metal production, which adopts a worm gear transmission structure in the transmission component, and synchronously drives the rotation of the lifting component, the air supply of the blowing component, and the scraping of the chip removal component through a single servo motor. While ensuring cutting accuracy, it realizes the linkage control of the whole process of sheet metal cutting, slag cleaning, equipment cooling and chip removal, which significantly improves the reliability, efficiency and maintenance convenience of laser cutting equipment. At the same time, it reduces the number of power sources and reduces energy consumption. Moreover, the servo motor is equipped with a self-locking device, which automatically locks the output shaft when the machine stops to avoid accidental rotation in the non-working state and ensures that the support cone has stable support performance.

[0032] 5. An intelligent laser cutting device and method based on sheet metal production, during laser cutting operations, a baffle is physically blocked by the staggered arrangement of the through slot and the waste collection port. This design prevents molten slag and debris generated during the cutting process from falling directly into the dust collection chamber, causing premature accumulation of molten slag in the chamber. This accumulation can lead to blockage or even jamming of the scraper before it starts running. With the baffle's blocking design, molten slag only enters the dust collection chamber before the scraper starts running. At this time, the scraper starts simultaneously, and the molten slag is promptly pushed to the molten slag output port, avoiding the problem of molten slag accumulation and blockage in the dust collection chamber. In addition, the waste collection port is designed to be blocked first and then opened, which can prevent external dust, oil, and other debris from entering the dust collection chamber when not in operation, and prevent the parts to be cut from accidentally falling into the dust collection chamber through the waste collection port during placement. This avoids contaminating the internal environment or interfering with the operation of the subsequent chip removal components, ensuring the normal discharge of cutting waste.

[0049] 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.

[0050] This invention provides four technical solutions: an intelligent laser cutting device based on sheet metal production, specifically including the following embodiments:

[0051] like Figures 1-5 The first embodiment is shown: an intelligent laser cutting device based on sheet metal production, including a cutting table 1, and further comprising:

[0052] The translation mechanism includes a transverse translation mechanism 2 that is slidably mounted on the top of the cutting table 1, a longitudinal translation mechanism 3 that is slidably mounted on the top of the transverse translation mechanism 2, and both the transverse translation mechanism 2 and the longitudinal translation mechanism 3 are controlled by an intelligent control box to control their running trajectories. A laser cutting head 4 for sheet metal cutting is mounted on one side of the bottom end of the longitudinal translation mechanism 3.

[0053] Multiple support mechanisms 5 are evenly arranged inside the cutting table 1 to work together to support the sheet metal parts to be cut.

[0054] like Figures 4-13A second embodiment is shown, differing from the first in that the support mechanism 5 further includes a support box 51 and a partition 52 fixedly disposed inside the support box 51. The partition 52 divides the internal space of the support box 51 into a transmission chamber 53 and a dust collection chamber 54. The transmission chamber 53 is equipped with a lifting assembly 57 for supporting the sheet metal parts and a blowing assembly 58 for blowing away molten slag accumulated on the surface of the support box 51 and cooling the lifting assembly 57. The molten slag blown away by the blowing assembly 58 is collected and automatically discharged by a chip removal assembly disposed in the dust collection chamber 54. A ramp is provided at the connection between the tops of the transmission chamber 53 and the dust collection chamber 54, allowing the molten slag to slide down to the top of the dust collection chamber 54. A dust discharge port is provided at the end of the dust collection chamber 54 near the molten slag outlet 6.

[0055] Two transmission components 523 are respectively disposed on both sides inside the transmission chamber 53, and are used to transmit power between the chip removal component, the lifting component 57 and the blowing component 58.

[0056] The slag outlet 6 is located on one side of the outer wall of the cutting table 1 and is used to provide a channel for the discharge of slag from the multiple support mechanisms 5.

[0057] In this embodiment, the top of the carrier box 51 is provided with an installation through groove 55, and multiple cleaning through grooves 56 are evenly provided on both sides of the inner wall of the installation through groove 55.

[0058] In this embodiment, the chip removal assembly includes multiple waste collection ports 524 located on the top of the carrier box 51 and directly above the dust collection chamber 54. Wedge plates 59 are fixedly installed on the top of the carrier box 51 and on both sides of each waste collection port 524. A first movable through groove 510 is provided on the inner wall of the dust collection chamber 54. A baffle 511 is slidably installed inside the first movable through groove 510. Multiple docking through grooves 512 are evenly provided on the top of the baffle 511. The multiple docking through grooves 512 and the multiple waste collection ports 524 are staggered. A vertical rod 513 is also fixedly installed on the side wall of the baffle 511. Guide rods 514 are fixedly installed on both sides of the outer wall of the vertical rod 513. A spring 515 is slidably sleeved on the outer wall of the guide rod 514. A second movable through groove 516 for the movement of the vertical rod 513 is provided on the outer wall of the dust collection chamber 54. The vertical rod 513 can reciprocate inside the second movable through groove 516. Both sides of the inner wall of the second movable through groove 516 are provided with elongated holes for the movement of guide rods 514. The two guide rods 514 are slidably arranged in the elongated holes at corresponding positions. The spring 515 is arranged between the vertical rod 513 and the side wall of the second movable through groove 516.

[0059] In this embodiment, a slag output unit is disposed inside the dust collection chamber 54 and directly below the baffle 511. The slag output unit includes second gears 519 rotatably disposed on both sides of the inner wall of the dust collection chamber 54. Two second toothed belts 520 are sleeved on the outer walls of the two second gears 519. Multiple scrapers 521 are uniformly fixed on the outer walls of the two second toothed belts 520. A connecting shaft is also fixedly disposed at one end of the second gear 519. The connecting shaft rotatably passes through the bearing box 51 and a disc 517 is fixedly disposed thereon. Multiple protrusions 518 for driving the vertical rod 513 to move are uniformly fixed on the outer wall of the disc 517. A protective cover is disposed on the outside of the second gear 519 to prevent waste slag from falling onto the surface of the second gear 519 and to ensure that the second gear can operate smoothly and stably.

[0060] In this embodiment, when the vertical rod 513 moves under the push of the protrusion 518, the multiple mating slots 512 and the waste collection port 524 on the baffle 511 can change from an interleaved state to an overlapping state, and the second gear 519 is driven by a servo motor. Initially, the mating slots 512 are housed in the first movable slot 510, at which time there is no overlap between the mating slots 512 and the waste collection port 524; when the scraper 521 moves, it can contact the bottom of the dust collection chamber 54. The discs 517 in the multiple support mechanisms 5 are connected by connecting shafts and are driven by the same servo motor. The output shaft of the servo motor is equipped with a self-locking device, which can automatically release the lock of the output shaft when working and automatically lock the output shaft when stopping.

[0061] like Figure 14 The third embodiment is shown, which differs from the second embodiment in that: the lifting assembly 57 includes a roller 571, a plurality of supporting cones 572 are uniformly fixed on the outer wall of the roller 571, the two ends of the roller 571 rotate through the bearing box 51 and are fixedly provided with a first gear 573, and a first toothed belt 574 is sleeved on the outer wall of the first gear 573. The first toothed belt 574 is sleeved on the outer wall of the first gear 573 and the third gear 5232. Four support cones 572 are evenly arranged on the circular cross-section of the roller 571. The roller 571 rotates 90 degrees each time according to the preset program. Therefore, one support cone 572 is always vertically upward, and the other two support cones 572 are located in the cleaning grooves 56 on both sides respectively. The two cleaning grooves 56 at each relative position are opposite to the four support cones 572 on the same circular cross-section. That is, the four support cones 572 on the same circular cross-section can rotate freely in the two cleaning grooves 56 at the relative positions. The width of the cleaning groove 56 can meet the needs of the support cones 572 to pass through while also scraping off the slag on their surface.

[0062] like Figure 15A fourth embodiment is shown, differing from the third embodiment in that: the purging assembly 58 includes an exhaust assembly and an air supply assembly, with the air supply assembly positioned below the exhaust assembly. The exhaust assembly includes a sealing plate 581 fixedly disposed inside the transmission chamber 53 and an exhaust channel 582 formed on the top side of the sealing plate 581. A slag discharge nozzle 583, communicating with the exhaust channel 582, is fixedly disposed at the bottom of the sealing plate 581. A lower air nozzle 584 is fixedly disposed on the top side of the sealing plate 581, and an upper air nozzle 585 is fixedly disposed on the top of the carrier box 51, above the lower air nozzle 584. A long strip-shaped channel is formed on the side wall of the partition plate 52, and the slag discharge nozzle 583 is connected to the long strip-shaped channel.

[0063] In this embodiment, the air supply assembly includes multiple bellows-type airbags 586 connected by pipes. Each bellows-type airbag 586 is connected to a lower air nozzle 584 and an upper air nozzle 585 via an air pipe 587. A drive shaft 588 is rotatably mounted on the inner wall of the transmission chamber 53 above the bellows-type airbags 586. A cam 589 for compressing the bellows-type airbags 586 to expel air is fixedly sleeved on the outer wall of the drive shaft 588 above each bellows-type airbag 586. The transmission assembly 523 is connected to the drive shaft 588.

[0064] The design of "sealing and then opening the slag collection port" ensures that when the lifting component 57 rotates, the slag is first scraped to the top of the carrying box 51. At this time, the baffle 511 seals the collection port. When the blowing component 58 is activated, that is, when the bellows-type airbag 586 is squeezed and vented by the cam 589, the baffle 511 slides open the collection port simultaneously. The blowing airflow accurately guides the concentrated slag through the overlapping docking groove 512 and the slag collection port 524 into the dust collection chamber 54. Then, it is pushed to the slag output port 6 by the scraper 521. This coordinated slag discharge mechanism of "concentrated accumulation - synchronous blowing - directional pushing" significantly improves the efficiency and thoroughness of slag cleaning and avoids secondary adhesion of slag on the cutting table or in the transmission chamber 53.

[0065] In this embodiment, the transmission assembly 523 includes a rotating shaft 5231 fixedly mounted inside the transmission chamber 53 by a bracket. A third gear 5232 and a worm gear 5233 are fixedly mounted at both ends of the rotating shaft 5231, respectively. A worm 5234 meshes above the worm gear 5233. The worm 5234 is rotatably mounted on the inner wall of the transmission chamber 53, and one end of the worm 5234 rotatably passes through the partition 52 and connects with one of the second gears 519.

[0066] This invention also provides an intelligent laser cutting method based on sheet metal production, and an intelligent laser cutting device for sheet metal production. The method includes the following steps:

[0067] Step 1: Multiple lifting components 57 jointly lift the sheet metal to be cut. After the laser cutting head 4 finishes the sheet metal cutting operation, the lifting components 57 rotate at a preset angle, and the slag attached to the surface of the lifting components 57 is scraped off and accumulates on the top of the carrier box 51.

[0068] Step 2: While the lifting component 57 is rotating, the blowing component 58 is driven by power and outputs airflow in a short time. The airflow blows the molten slag at the top of the transmission chamber 53 toward the top of the dust collection chamber 54.

[0069] Step 3: The chip removal component collects the molten slag blown by the blowing component 58 and collects the molten slag inside the dust collection chamber 54. When the lifting component 57 rotates to switch the support surface, it pushes the molten slag inside the dust collection chamber 54 to the molten slag outlet 6.

[0070] The specific process is as follows: the servo motor is controlled by the intelligent control box to rotate at a preset angle, the second gear 519 rotates under the drive of the servo motor, multiple scrapers 521 continuously scrape the slag at the bottom of the dust collection chamber 54 and push it to the slag output port 6. At the same time as the second gear 519 rotates, the disc 517 is driven to rotate synchronously. When the protrusion 518 rotates, it meets the vertical rod 513 and pushes the vertical rod 513 to move along the fixed direction of the inner cavity of the second movable through groove 516. The spring 515 in one direction is squeezed and undergoes elastic deformation. At the same time as the vertical rod 513 moves, the baffle 511 is driven to slide along the first movable through groove 510 for a fixed distance. Multiple docking through grooves 512 and multiple corresponding waste slag collection ports 524 overlap with each other. The slag enters the dust collection chamber 54 through the overlapping position of the docking through grooves 512 and waste slag collection ports 524.

[0071] At the same time, the second gear 519 rotates synchronously, driving the worm 5234 to rotate. The worm 5234 drives the worm wheel 5233 to rotate at a preset angle. The power drives the roller shaft 571 to rotate exactly ninety degrees through the rotating shaft 5231, the third gear 5232 and the first toothed belt 574. One row of supporting cones 572 rotates out from the mounting slot 55 at the corresponding position.

[0072] At the same time, the rotating shaft 5231 drives the transmission shaft 588 to rotate at a preset angle. Multiple protrusions on the cam 589 cyclically squeeze the bellows-type airbags 586 at the corresponding positions. The air squeezed out by the bellows-type airbags 586 is delivered to the lower air nozzle 584 and the upper air nozzle 585 through multiple air pipes 587 respectively. The air blown out by the first toothed belt 574 is concentrated in the relatively closed space formed by the sealing plate 581 and the inner wall of the transmission chamber 53. The air blows the support cone 572 located in this space and carries a small amount of molten slag debris located on the top of the sealing plate 581 into the dust collection chamber 54 through the exhaust channel 582 and the slag discharge nozzle 583.
