Description

Technical Field

[0001] The present invention relates to the field of laser cutting technology, and in particular to an intelligent laser cutting device and method based on sheet metal production. Background Art

[0002] Intelligent laser cutting devices are core equipment for achieving efficient and precise processing in modern manufacturing. They integrate high-power lasers, intelligent control systems, AI visual recognition, and automated loading and unloading systems. They use high-energy-density laser beams to interact with materials to melt, vaporize, or ablate them, while using high-speed airflow to blow away the molten material to complete the cutting.

[0003] Among them, since sheet metal parts are usually made of flat materials, cutting can be used to divide the raw materials into the basic contours required for the design to facilitate subsequent reprocessing. Laser cutting devices are usually used for cutting in this process.

[0004] Reference publication number CN223146284U discloses a positioning device for sheet metal laser cutting, which is supported by multiple support bars. The motor is started to drive the bidirectional screw rod to rotate, so that the two positioning plates are close to each other. When the positioning plate moves, it will push the rotating rod to rotate. The rotating rod is screwed into the groove of the slide bar with the fixed axis as the center. When the positioning plate leaves the rotating rod, it is reset by gravity. The positioning plate clamps the two sides of the sheet metal and positions it left and right. The electric push rod is started to push the slide bar. The slide bar approaches the sheet metal along the slide groove and pushes the sheet metal backward to the fixed plate through multiple rotating rods, thereby positioning the front and back of the sheet metal. The positioning is automatically adjusted, the operation is simple, the positioning efficiency is improved, the positioning cost is reduced, and the positioning of the sheet metal is convenient. The sheet metal laser cutting device in the above-mentioned prior art has the following defects in actual use: 1) During the laser cutting process of sheet metal, sheet metal slag will fall onto the support bars and cutting table under the action of gravity. After cooling and solidifying, it forms shell-like impurities that accumulate in the support bar teeth. The slag accumulation will change the actual height of the support teeth, resulting in a focal length deviation between the workpiece and the laser cutting head, causing fluctuations in the cutting width or incomplete cutting, affecting the dimensional accuracy of the workpiece. Manual cleaning of the slag requires downtime, which increases the batch processing cycle of the workpiece. 2) The residual laser energy in the above-mentioned patent frequently acts on the surface of the support bar, which can easily cause the temperature of the support bar to rise sharply, easily cause the support bar to deform at high temperature, and make the top of the support bar have an uneven support surface, making it impossible to form a stable support for the workpiece.

[0005] Therefore, the present invention proposes an intelligent laser cutting device and method based on sheet metal production to solve the above problems. Summary of the Invention

[0006] In response to the deficiencies in the prior art, the present invention provides an intelligent laser cutting device and method based on sheet metal production, which solves the current problems in laser cutting of sheet metal, where sheet metal slag falls to the support bars and cutting table under the action of gravity, and after cooling, it forms shell-like impurities and accumulates in the tooth gaps, changing the actual height of the support teeth, causing focal length deviation, causing fluctuations in the cutting width or incomplete cutting, affecting dimensional accuracy, and manual cleaning requires machine downtime, which prolongs the processing cycle; and the long-term action of the residual energy of the laser causes the temperature of the support bar to rise sharply, making it prone to high-temperature deformation, resulting in an uneven top support surface and an inability to stably support the workpiece.

[0010] Furthermore, a slag output unit is provided inside the dust collecting chamber and directly below the baffle, and the slag output unit includes a second gear rotatably arranged on both sides of the inner wall of the dust collecting chamber, and two second toothed belts are jointly sleeved on the outer walls of the two second toothed belts, and a plurality of scrapers are evenly fixed on the outer walls of the two second toothed belts, and a connecting shaft is also fixedly provided at one end of the second gear, which rotates through the carrying box and is fixed with a disc, and a plurality of protrusions for driving the vertical rod to move are evenly fixedly provided on the outer wall of the disc.

[0011] Furthermore, when the vertical rod is pushed by the protrusion to move, the multiple docking grooves and the waste collection port on the baffle can be transformed from a staggered state to an overlapping state, and the second gear is driven by a servo motor.

[0012] Furthermore, the lifting assembly includes a roller shaft, and a plurality of supporting cones are evenly fixed on the outer wall of the roller shaft. The two ends of the roller shaft rotate through the carrying box and are fixed with a first gear, and a first toothed belt is sleeved on the outer wall of the first gear.

[0013] Furthermore, the purge assembly includes an exhaust assembly and an air supply assembly, the air supply assembly is arranged below the exhaust assembly, the exhaust assembly includes a sealing plate fixedly arranged inside the transmission chamber and an exhaust groove opened on the top side of the sealing plate, the bottom of the sealing plate is fixedly provided with a slag discharge nozzle connected to the exhaust groove, the top side of the sealing plate is fixedly provided with a lower air nozzle, and the top of the carrying box and above the lower air nozzle is fixedly provided with an upper air nozzle.

[0014] Furthermore, the air supply assembly includes multiple bellows-type airbags connected by pipes. Each of the bellows-type airbags is connected to the lower and upper air nozzles via air pipes.

[0015] The present invention also discloses an intelligent laser cutting method based on sheet metal production, which is used for an intelligent laser cutting device based on sheet metal production. The method comprises the following steps: Step 1: Multiple lifting components jointly lift the sheet metal to be cut. After the laser cutting head completes the sheet metal cutting operation, the lifting components rotate to a preset angle, and the slag attached to the surface of the lifting components is scraped off and accumulated on the top of the carrying box; Step 2: The purge assembly is driven by power while the lifting assembly rotates, and outputs airflow in a short period of time, and the airflow blows the slag on the top of the transmission chamber toward the top of the dust collection chamber; Step 3: The chip removal component collects the slag blown by the purge component and collects the slag inside the dust collection chamber. When the lifting component rotates and switches the support surface, the slag inside the dust collection chamber is pushed to the slag output port.

[0016] The present invention provides an intelligent laser cutting device and method for sheet metal production. Compared with the existing technology, it has the following advantages: 1. An intelligent laser cutting device and method based on sheet metal production, which uses a servo motor to drive a scraper to intermittently scrape in the dust collection chamber. The design combines a slope surface and a wedge plate to guide the slag to slide naturally into the dust collection chamber, so that the slag automatically slides to the slag output port, achieving unmanned continuous chip removal, greatly reducing downtime for cleaning. The baffle is driven by a bump, and the docking slot is opened only when chip removal is required. The waste slag collection port is closed at other times to avoid slag backflow and sheet metal parts falling and not being picked up, thereby ensuring that the chip removal channel is always unobstructed.

[0017] 2. An intelligent laser cutting device and method based on sheet metal production, through the rotation switching design of the four supporting cones on the same cross-section of the lifting component, always keeps at least one cone vertically upward to support the sheet metal. When switching the supporting surface, the scraping groove can automatically scrape off the slag on the surface of the supporting cone, keeping the supporting surface clean, ensuring that the supporting surface is continuously flat, and avoiding the problem that the end face formed at the top of the supporting cone cannot form a flat plane due to slag accumulation, thereby always maintaining stable support of the sheet metal by the supporting cone and ensuring cutting accuracy; secondly, the four supporting cones on the same cross-section work alternately, so that the replaced supporting cone can have enough time to cool down, reducing the risk of deformation and improving cutting stability.

[0018] 3. An intelligent laser cutting device and method based on sheet metal production. The purge component squeezes the bellows-type airbag through the cam to generate high-speed airflow, while cooling the supporting cone on the surface of the lifting component and blowing the slag on the top of the transmission chamber, laying the foundation for subsequent slag collection, while preventing structural deformation or life degradation caused by high temperature. In addition, the sealing plate and the transmission chamber form a relatively closed space, and the airflow concentrates on blowing the replaced supporting cone to further blow away the residual slag particles.

[0019] 4. An intelligent laser cutting device and method based on sheet metal production adopts a worm gear transmission structure through the transmission component, and uses a single servo motor to synchronously drive the rotation of the lifting component, the air supply of the purge component, and the scraping of the chip removal component. While ensuring the cutting accuracy, it realizes the linkage control of the entire process of sheet metal cutting, slag cleaning, equipment cooling and chip removal, significantly improving the reliability, efficiency and maintenance convenience of the laser cutting equipment, while reducing the number of power sources and lowering energy consumption. In addition, the servo motor is equipped with a self-locking device, which automatically locks the output shaft when it stops, avoiding accidental rotation in the non-working state, and ensuring that the supporting cone has stable support performance.

[0020] 5. An intelligent laser cutting device and method based on sheet metal production. During the laser cutting operation, the baffle forms a physical blockage by staggering the connecting groove and the waste slag collection port. This design can prevent the slag and debris generated during the cutting process from falling directly into the dust collecting chamber, causing local slag to accumulate prematurely in the chamber and accumulate into blocks when the scraper is not started, resulting in obstruction or even jamming of the scraper during operation. However, through the blocking design of the baffle, the slag only enters the dust collecting chamber before the scraper is operated. At this time, the scraper is started synchronously, and the slag is pushed to the slag output port in time, avoiding the problem of slag accumulation and blockage in the dust collecting chamber; in addition, the waste slag collection port is set to be sealed first and then opened, which can ensure that external dust, oil and other debris are prevented from invading the dust collecting chamber in the non-working state, and prevent the parts to be cut from accidentally falling into the dust collecting chamber through the waste slag collection port during placement, thereby avoiding polluting the internal environment or interfering with the operation of subsequent chip removal components, and ensuring the normal discharge of cutting waste.

DETAILED DESCRIPTION

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] The present invention provides four technical solutions: an intelligent laser cutting device based on sheet metal production, specifically including the following embodiments: like Figure 1-Figure 5 A first embodiment is shown: an intelligent laser cutting device based on sheet metal production, comprising a cutting table 1, and further comprising: The translation mechanism includes a transverse translation mechanism 2 slidably arranged on the top of the cutting table 1, a longitudinal translation mechanism 3 is slidably arranged on the top of the transverse translation mechanism 2, and the operation trajectory of the transverse translation mechanism 2 and the longitudinal translation mechanism 3 are both controlled by an intelligent control box. A laser cutting head 4 for sheet metal cutting is arranged on one side of the bottom end of the longitudinal translation mechanism 3; A plurality of support mechanisms 5 are evenly arranged inside the cutting table 1 for cooperating to support the sheet metal parts to be cut.

[0025] like Figure 4-13 The second embodiment is shown, which differs from the first embodiment in that the support mechanism 5 also includes a carrying box 51 and a partition 52 fixedly arranged inside the carrying box 51. The partition 52 divides the internal space of the carrying box 51 into two spaces: a transmission chamber 53 and a dust collecting chamber 54. The transmission chamber 53 is provided with a lifting assembly 57 for supporting the sheet metal parts and a purge assembly 58 for blowing away the slag accumulated on the surface of the carrying box 51 and cooling the lifting assembly 57. The accumulated slag blown by the purge assembly 58 is collected and automatically discharged through the chip removal assembly arranged in the dust collecting chamber 54. A slope surface is provided at the position where the top of the transmission chamber 53 and the dust collecting chamber 54 are connected, so that the slag can slide down to the top of the dust collecting chamber 54 through the slope surface. A dust discharge port is provided at one end of the dust collecting chamber 54 close to the slag output port 6; The two transmission assemblies 523 are respectively arranged on both sides of the transmission chamber 53 for transmitting power between the chip removal assembly, the lifting assembly 57 and the purge assembly 58.

[0026] The slag outlet 6 is provided on one side of the outer wall of the cutting table 1 and is used to provide a channel for discharging the slag in the plurality of support mechanisms 5 .

[0027] In this embodiment, a mounting slot 55 is formed on the top of the carrying box 51 , and a plurality of cleaning slots 56 are evenly formed on both sides of the inner wall of the mounting slot 55 .

[0028] In this embodiment, the chip removal assembly includes a plurality of waste collection ports 524 opened on the top of the carrying box 51 and located directly above the dust collecting chamber 54, and a wedge plate 59 is fixedly provided on the top of the carrying box 51 and on both sides of each waste collection port 524, a first movable groove 510 is provided on the inner wall of the dust collecting chamber 54, a baffle 511 is slidingly provided inside the first movable groove 510, a plurality of docking grooves 512 are evenly provided on the top of the baffle 511, and the plurality of docking grooves 512 and the plurality of waste collection ports 524 are staggered, a vertical rod 513 is also fixedly provided on the side wall of the baffle 511, and guide rods 514 are fixedly provided on both sides of the outer wall of the vertical rod 513, a spring 515 is slidingly sleeved on the outer wall of the guide rod 514, and a second movable groove 516 for the movement of the vertical rod 513 is provided on the outer wall of the dust collecting chamber 54. The vertical rod 513 can move back and forth inside the second movable groove 516. Long circular holes for the movement of the guide rod 514 are opened on both sides of the inner wall of the second movable groove 516. The two guide rods 514 are respectively slidably set in the long circular holes at corresponding positions, and the spring 515 is set between the vertical rod 513 and the side wall of the second movable groove 516.

[0029] In this embodiment, a slag output unit is disposed within the dust collection chamber 54, directly below the baffle 511. This unit comprises second gears 519 rotatably mounted on either side 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 evenly fixed to the outer walls of the two second toothed belts 520. A connecting shaft is also fixedly mounted on one end of the second gear 519. This connecting shaft rotatably passes through the carrier box 51 and is fixedly mounted with a circular disc 517. Multiple protrusions 518 for driving the vertical rod 513 are evenly fixed to the outer wall of the circular disc 517. A protective shield is provided on the exterior of the second gear 519 to prevent waste slag from falling onto the surface of the second gear 519, ensuring smooth and stable operation of the second gear.

[0030] In this embodiment, when the vertical rod 513 is pushed by the protrusion 518 and moves, the multiple docking grooves 512 and the waste collection port 524 on the baffle 511 can be changed from a staggered state to an overlapping state, and the second gear 519 is driven by a servo motor. The docking groove 512 is initially received in the first movable groove 510. At this time, there is no overlapping part between the docking groove 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 a connecting shaft and are driven by the same servo motor. A self-locking device is provided on the output shaft of the servo motor, which can automatically unlock the output shaft when working and automatically lock the output shaft when it stops.

[0031] like Figure 14A third embodiment is shown, which differs from the second embodiment in that the lifting assembly 57 includes a roller 571, and a plurality of supporting cones 572 are evenly fixedly provided on the outer wall of the roller 571. Both ends of the roller 571 rotate through the carrying box 51 and are fixedly provided with a first gear 573. A first toothed belt 574 is sleeved on the outer wall of the first gear 573. The first toothed belt 574 is jointly sleeved on the outer walls of the first gear 573 and the third gear 5232, and four supporting cones 572 are evenly arranged on the circular cross-section of the roller shaft 571. The roller shaft 571 is controlled to rotate ninety degrees each time according to a preset program. Therefore, there is always one supporting cone 572 vertically upward, and the other two supporting cones 572 are respectively located in the scraping grooves 56 on both sides. The two scraping grooves 56 at each relative position are opposite to the four supporting cones 572 on the same circular cross-section, that is, the four supporting cones 572 located on the same circular cross-section can rotate freely in the two scraping grooves 56 at the relative position, and the width of the scraping groove 56 can meet the passage of the supporting cones 572 while scraping off the slag on its surface.

[0032] like Figure 15 A fourth embodiment is shown, which differs from the third embodiment in that: the purge assembly 58 includes an exhaust assembly and an air supply assembly, the air supply assembly being located below the exhaust assembly; the exhaust assembly including a sealing plate 581 fixedly mounted within the transmission chamber 53 and an exhaust slot 582 defined on one side of the top of the sealing plate 581; a slag discharge nozzle 583 connected to the exhaust slot 582 is fixedly mounted on the bottom of the sealing plate 581; a lower air nozzle 584 is fixedly mounted on one side of the top of the sealing plate 581; and an upper air nozzle 585 is fixedly mounted on the top of the carrying box 51 and above the lower air nozzle 584. An elongated slot is defined on the sidewall of the partition 52, and the slag discharge nozzle 583 is connected to the elongated slot.

[0033] In this embodiment, the air supply assembly includes a plurality of bellows-type airbags 586 connected by pipes. Each of the bellows-type airbags 586 is connected to the lower air nozzle 584 and the upper air nozzle 585 via an air pipe 587. A transmission shaft 588 is rotatably mounted on the inner wall of the transmission chamber 53, above the bellows-type airbags 586. A cam 589 is fixedly mounted on the outer wall of the transmission shaft 588, above each bellows-type airbag 586, for squeezing the bellows-type airbags 586 to release air. The transmission assembly 523 is connected to the transmission shaft 588.

[0034] The design of "first blocking and then opening the waste 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 blocks the collection port. When the purge component 58 is started, that is, when the bellows airbag 586 is squeezed and exhausted by the cam 589, the baffle 511 synchronously slides to open the collection port. The purge airflow accurately guides the concentrated and accumulated slag into the dust collection chamber 54 through the overlapping docking grooves 512 and the waste slag collection port 524, and then is pushed to the slag output port 6 by the scraper 521. This "concentrated accumulation-synchronous purge-directional push" collaborative slag discharge mechanism significantly improves the efficiency and thoroughness of slag cleaning, and avoids secondary adhesion of slag on the cutting table or the transmission chamber 53.

[0035] In this embodiment, the transmission assembly 523 includes a rotating shaft 5231 fixedly mounted within the transmission chamber 53 via a bracket. A third gear 5232 and a worm gear 5233 are fixedly mounted at each end of the rotating shaft 5231. 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 rotates through the partition 52 and is connected to one of the second gears 519.

[0036] The present invention also provides an intelligent laser cutting method based on sheet metal production, which is used for an intelligent laser cutting device based on sheet metal production. The method comprises the following steps: Step 1: Multiple lifting assemblies 57 jointly lift the sheet metal to be cut. After the laser cutting head 4 completes the sheet metal cutting operation, the lifting assemblies 57 rotate to a preset angle. The slag attached to the surface of the lifting assemblies 57 is scraped off and accumulated on the top of the carrying box 51. Step 2: The purge assembly 58 is driven by power while the lifting assembly 57 rotates and outputs airflow in a short period of time. The airflow blows the slag on the top of the transmission chamber 53 toward the top of the dust collection chamber 54. Step 3: The chip removal assembly collects the slag blown by the purge assembly 58 and collects the slag inside the dust collection chamber 54. When the lifting assembly 57 rotates and switches the support surface, the slag inside the dust collection chamber 54 is pushed to the slag output port 6. The specific process is as follows: the servo motor is controlled by the intelligent control box to rotate a preset angle, and 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 collecting chamber 54 and push it to the slag output port 6. While the second gear 519 rotates, the disc 517 is synchronously driven to rotate. 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 groove 516. The spring 515 in one direction is squeezed and elastically deformed. When the vertical rod 513 moves, the baffle 511 is synchronously driven to slide a fixed distance along the first movable groove 510. Multiple docking grooves 512 and multiple waste slag collection ports 524 at corresponding positions coincide with each other. The slag enters the dust collecting chamber 54 through the overlapping position of the docking groove 512 and the waste slag collection port 524; At the same time, the second gear 519 rotates and simultaneously drives the worm 5234 to rotate. The worm 5234 drives the worm wheel 5233 to rotate by a preset angle. The power is driven by the rotating shaft 5231, the third gear 5232 and the first toothed belt 574 to drive the roller shaft 571 to rotate exactly 90 degrees. One row of supporting cones 572 rotates out of the mounting slots 55 at the corresponding positions. At the same time, the rotating shaft 5231 drives the transmission shaft 588 to rotate a preset angle, and the multiple protrusions arranged on the cam 589 cyclically squeeze the bellows-type airbag 586 at the corresponding position. The air squeezed out by the bellows-type airbag 586 is respectively transported to the lower air nozzle 584 and the upper air nozzle 585 through multiple air pipes 587. 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 supporting cone 572 located in the space and carries a small amount of slag debris located on the top of the sealing plate 581 into the dust collecting chamber 54 through the exhaust groove 582 and the slag discharge nozzle 583.
