Description

Technical Field

[0001] This invention relates to the field of laser cutting machine technology, and more specifically to a laser cutting device for processing heat dissipation mesh. Background Technology

[0002] Laser cutting technology, due to its high precision, high efficiency, and excellent cutting quality, has been widely used in the processing of sheet metal, especially in the production of thin-plate parts with dense perforated structures such as heat sinks, sieves, and perforated plates. Heat sinks are typically made of thin sheet materials such as stainless steel and aluminum alloys. Laser cutting creates a large number of regularly arranged mesh holes, requiring high standards for the quality of the cutting edges, dimensional accuracy, and flatness of the sheet metal. During laser cutting, the high-energy laser beam instantly melts or even vaporizes the metal material, and the molten metal is expelled from the kerf under the purging of assist gas. This process inevitably generates a large amount of high-temperature metal spatter, fumes, and slag particles. Some of these cutting products are discharged downwards with the assist gas, while others fly upwards or outwards.

[0003] In existing technologies, to reduce the contamination of the processing environment and workpiece surface by cutting contaminants, a dust collection system is usually installed around the cutting head to remove the smoke and splatter generated during the cutting process. However, in actual use, it has been found that during long-term continuous cutting and dust collection, the inner wall of the pipes of such dust collection systems is prone to the adhesion and accumulation of contaminants such as high-temperature molten slag and metal particles. After these contaminants come into contact with the inner wall of the pipe, some of them will adhere and accumulate, causing the effective cross-sectional area of ​​the dust collection channel used during cutting to gradually decrease, the dust collection efficiency to drop significantly, resulting in ineffective dust collection. The smoke and splatter generated during cutting cannot be dealt with in time, which will contaminate the surface of the sheet metal, optical lenses, and moving parts of the machine tool, seriously affecting the cutting quality.

[0004] To address the aforementioned pipe blockage problem, existing solutions largely rely on periodic manual shutdowns for cleaning, or the use of larger pipe diameters to delay blockage occurrence. Manual... Cleaning methods are inefficient, and frequent downtime severely impacts production efficiency; while simply increasing the pipe diameter only postpones blockage but cannot fundamentally solve the problem. This presents a problem and occupies more installation space. Furthermore, the adhesion of high-temperature splashes to the inner wall of the pipe is closely related to its temperature—the higher the temperature, the greater the melting... The stronger the adhesion of the slag, the greater its adhesion after cooling. Therefore, how to continuously and automatically clean contaminants from the inner wall of the pipe during the dust collection process, and simultaneously... Reducing the adhesiveness of pollutants is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0005] The purpose of this invention is to provide a laser cutting device for heat dissipation mesh processing, which solves the problem that in traditional laser cutting devices, high-temperature molten slag, metal particles and other contaminants easily adhere to and accumulate on the inner wall during cutting, causing a significant decrease or even ineffective dust collection efficiency, and thus affecting the cutting quality.

[0017] The above-mentioned and other technical features and advantages of the present invention will be described in more detail below with reference to the accompanying drawings.

[0018] This invention provides a technical solution: a laser cutting device for processing heat dissipation mesh, such as... Figures 1-5 As shown, the equipment includes a frame 1 and a lifting component 5. The top of the frame 1 is equipped with a support platform 2 and a three-axis motion mechanism 3. The three-axis motion mechanism 3 includes three core motion axes: the X-axis mechanism (usually referring to the lateral movement of the beam, i.e., left and right movement; on large-format machine tools, to improve efficiency and stability, the X-axis mechanism often uses double-sided drive, i.e., two servo motors synchronously drive both sides of the gantry); the Y-axis mechanism (usually referring to the overall longitudinal movement of the gantry, i.e., forward and backward movement; the Y-axis mechanism undertakes the main stroke, therefore it often uses gear and rack transmission to achieve long-distance... The high-speed motion and Z-axis mechanism (which controls the lifting and lowering motion of the cutting head) typically employ high-precision ball screw transmission to ensure focusing accuracy. The three-axis motion mechanism 3 is equipped with a laser cutting head 4, which is mainly mounted on the Z-axis that controls the lifting and lowering motion. As is well known to those skilled in the art, the working principles and wiring methods of the three-axis motion mechanism 3 and the laser cutting head 4 are commonplace and belong to conventional methods or common knowledge. They will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

[0019] The quality improvement component 5 is located on top of the three-axis motion mechanism 3. The quality improvement component 5 is used to improve the cutting quality of the heat dissipation mesh. The quality improvement component 5 includes a protective cover 51 located outside the laser cutting head 4, an annular filter shell 52 located outside the protective cover 51, an air pump 53, a self-cleaning suction pipe 54 located between the annular filter shell 52 and the protective cover 51, and a follow-drive support component. The laser cutting head 4 can pass through the protective cover 51 under the drive of the Z-axis motion mechanism. The self-cleaning suction pipe 54 located between the annular filter shell 52 and the protective cover 51 has upper and lower layers, and both layers are arranged in a ring array between the annular filter shell 52 and the protective cover 51. The self-cleaning suction pipe 54 of the upper and lower layers... The suction tubes 54 are staggered. The inner side of the annular filter shell 52 is provided with anti-clogging components. The air inlet end of the air pump 53 is connected to a connecting pipe, and the air outlet end of the air pump 53 is provided with an air outlet pipe. The anti-clogging components are arranged in a ring array on the inner side of the annular filter shell 52. The specific number of anti-clogging components depends on the number of connecting pipes. The number of anti-clogging components is the same as the number of connecting pipes, and one anti-clogging component corresponds to the position of one connecting pipe. One end of the connecting pipe is connected to the top of the annular filter shell 52. In this embodiment, four connecting pipes are provided, and the four connecting pipes are arranged in a ring on the annular filter shell 52. The inner wall of the annular filter shell 52 is fixed with an annular filter screen 526 for intercepting pollutants.

[0020] The self-cleaning suction tube 54 includes an initial tube 55 passing through the protective cover 51, a connecting tube 56 connected to the inside of the annular filter shell 52, and a power component. One end of the connecting tube 56 is sleeved on the outside of the initial tube 55 and fixedly connected to it. The initial tube 55 is inclined and passes through the protective cover 51. The connecting tube 56 is positioned along the inclined direction of the initial tube 55, and the two form a straight inclined direction after connection. Figure 3 As shown, the inner diameter of the connecting pipe 56 is larger than that of the initial pipe 55. A rotating ring 57 is rotatably connected between one end of the initial pipe 55 and the inner wall of the connecting pipe 56. A hollow connecting frame 58 is fixed to one end of the rotating ring 57. The hollow connecting frame 58 is located at the end of the initial pipe 55 inside the connecting pipe 56. Two scraper strips 59 are fixed on the hollow connecting frame 58. The two scraper strips 59 are located on the inner sides of the initial pipe 55 and the connecting pipe 56, respectively. One side of the two scraper strips 59 is attached to the inner wall of the initial pipe 55 and the connecting pipe 56, respectively. The material of the scraper strips 59 can be polyurethane or polytetrafluoroethylene, because both have good wear resistance and temperature resistance.

[0021] The bottom of the connecting pipe 56 is provided with an external threaded outlet 510, which is located below the hollow connecting frame 58. An internal threaded transparent collection box 511 is threadedly connected to the external threaded outlet 510. After a certain amount of cutting products are stored inside the internal threaded transparent collection box 511, the internal threaded transparent collection box 511 can be rotated off the external threaded outlet 510 to pour out the collected cutting products.

[0022] The power components include an air filter 512 fixed to one side of the triaxial motion mechanism 3, an air inlet pipe 513 fixed to the top of the annular filter housing 52, an annular pipe 514 fixed to one end of the connecting pipe 56, and a first fan blade 515 fixed to the outer wall of the rotating ring 57. A vortex tube 516 is provided on the top of the air filter 512. As is well known to those skilled in the art, the working principles and wiring methods of the air filter 512, vortex tube 516, and air pump 53 are common knowledge and are all conventional methods or common sense. Therefore, they will not be elaborated further here. Those skilled in the art can describe them according to their needs or... For convenient selection, the air filter 512 allows compressed air to pass through the porous filter material to remove contaminants, filtering out solid impurities such as liquid water, oil droplets, dust, and rust from the compressed air, providing a clean air source around the laser cutting head 4 at the rear end, and protecting the equipment from wear. The vortex tube 516 generates hot and cold airflows through the air passing through it, which can accurately spray low-temperature air into the processing area, effectively dealing with thermal warping and edge burning. The vortex tube 516 and the air filter 512 are connected by a tube body, and a valve is installed on the tube body to control whether the vortex tube 516 and the air filter 512 are connected by air. The cooling end of the vortex tube 516 is connected to two corrugated expansion tubes 517 via a T-junction. One end of each of the two corrugated expansion tubes 517 is connected to an inflation tube 513. The inflation tube 513 is connected to an annular tube 514 via a flexible hose. The number of flexible hoses in the annular tube 514 corresponds to the number of annular tubes 514 connected to it. An air inlet 518 extending into the inner side of the connecting tube 56 is provided on the annular tube 514. The air inlet 518 provides airflow to the first fan blade 515 to drive its rotation, and simultaneously provides cooling for the gas entering the connecting tube 56 and the cutting products. Figure 1As shown, in this embodiment, two slide grooves are opened on the top of the supporting slide rail arm 521. Slide arms slide in both slide grooves, and two corrugated telescopic tubes 517 are fixedly connected to the slide arms in the slide grooves closest to themselves. The corrugated telescopic tubes 517 can be restricted and supported by the slide arms, preventing the corrugated telescopic tubes 517 from falling down and affecting the use of other mechanisms. The two corrugated telescopic tubes 517 are fixed to the lifting frame 533 and the sliding frame 522 respectively by connecting rings. With the fixed restriction points on the lifting frame 533 and the sliding frame 522, the connection length between the corrugated telescopic tubes 517 and the inflation tube 513 can be limited.

[0023] The power unit also includes an annular box 519 fixed to the top of the inner wall of the protective cover 51. The annular box 519 wraps around the outside of the laser cutting head 4. The bottom of the annular box 519 is fixed with slag spray nozzles arranged in a ring array. The slag spray nozzles spray low-temperature gas around the cutting position, which is responsible for blowing away the molten slag and cooling the molten slag to a certain extent, so that the molten metal at the edge of the cut can be quickly solidified, reducing its flowability and the adhesion of the molten slag, so that the cutting position and the surrounding area can have fewer defects. The annular tube 514 is connected to a small annular tube 520 through a pipe. The small annular tube 520 is set on the periphery of the laser cutting head 4. The small annular tube 520 is connected to the annular box 519 through a pipe, providing low-temperature gas to the annular box 519.

[0024] The follow-drive support includes a support slide rail arm 521 fixed to the top of the three-axis motion mechanism 3. A sliding frame 522 slides on the support slide rail arm 521. A hydraulic cylinder 523 is fixed to the top of the sliding frame 522. As is well known to those skilled in the art, the working principle and wiring method of the hydraulic cylinder 523 are common and are all conventional means or common knowledge. They will not be described in detail here. Those skilled in the art can make any selection according to their needs or convenience. A lifting frame 533 is installed on the sliding frame 522. The air pump 53 is fixed to the inside of the lifting frame 533. One end of the extension rod of the hydraulic cylinder 523 is fixed to the top of the lifting frame 533. The sliding frame 522 and the Z motion axis mechanism equipped with the laser cutting head 4 are fixedly connected by a fixing plate so that it can move together with the Z motion axis when it moves laterally. The extension and retraction of the hydraulic cylinder 523 drives the protective cover 51 and the annular filter shell 52 to rise and fall, so that the protective cover 51 and the annular filter shell 52 adjust the distance between their bottom and the top of the metal plate to be cut.

[0025] The follow-drive support also includes two slide rails 524, which are respectively fixed to the front and rear outer side walls of the Z-axis mechanism. Each slide rail 524 has a sliding arm 525. Figure 2As shown, one end of each of the two sliding arms 525 is fixed to the corresponding connecting pipe by an annular block. When the extension rod of the oil cylinder 523 extends and retracts, driving the lifting frame 533 and the air pump 53 to rise and fall, the connecting pipe will drive the sliding arm 525 to rise and fall along the slide rail 524. The air pump 53 is connected to the sliding arm 525 and the slide rail 524 to improve the overall stability of the quality improvement component 5 structure.

[0026] The self-anti-clogging component includes a rotating rod 527 that rotates on the inner wall of the annular filter housing 52 via a support arm, and a protruding rod 528 that rotates on the inner wall of the annular filter housing 52 via a connecting rod. The protruding rod 528 is positioned above the filter screen 526. Figure 4 As shown, each self-clogging component has two symmetrically arranged protrusions 528 on the periphery of the rotating rod 527. A stirring blade 529 is fixed on the outer surface of the rotating rod 527. The stirring blade 529 is located near the bottom of the rotating rod 527. A transparent observation window is provided on the annular filter shell 52, which is located at the position of the stirring blade 529. The cutting product inside the annular filter shell 52 can be observed through this transparent observation window to see whether it needs to be discharged. One end of the rotating rod 527 extends to the top of the filter screen 526 and is fixed with a second fan blade 530. The second fan blade 530 is located inside one end of the connecting pipe. The airflow passing through the connecting pipe will drive the second fan blade 530 to rotate. The second fan blade 530 itself is made into an asymmetrical shape. The airflow can only push the second fan blade 530 to rotate in one direction. The rotation direction of the second fan blade 530 must be ensured to limit the rotation direction of the crossbar 532. A rubber striking head 531 is fixed on the protruding rod 528, such as Figure 5 As shown, one end of the rubber striking head 531 rests against the filter screen 526. Later, the weight of one end of the rubber striking head 531 can cause it to fall back onto the filter screen 526 to strike it. A crossbar 532 is fixed on the outer surface of the rotating rod 527. The height of the crossbar 532 corresponds to the position of the protruding rod 528. A slag discharge port is provided at the bottom of the annular filter shell 52. A threaded sealing cap is provided at the slag discharge port. The slag discharge port can be opened by rotating the threaded sealing cap to discharge the pollutants inside the annular filter shell 52. After the slag discharge is cleaned, the threaded sealing cap can be screwed onto the slag discharge port to seal it. At the same time, a water inlet is provided on the annular filter shell 52. A sealing plug is provided on the water inlet. Water is filled into the annular filter shell 52 through the water inlet. The water source position should not be higher than the opening of the connecting pipe 56 below, which is observed through the transparent observation window, to prevent water from entering the connecting pipe 56 later under the agitation of the stirring blade 529.

[0027] In use: Place the metal sheet on the support platform 2, and use the three-axis motion mechanism 3 to drive the laser cutting head 4 to move and cut the metal sheet into a metal heat dissipation mesh according to the instructions. When the laser cutting head 4 moves back and forth and laterally, it will drive the quality improvement component 5 to move back and forth through the support slide rail arm 521. Through the sliding frame 522 fixed to the Z motion axis mechanism, it will drive the protective cover 51, the annular filter shell 52, the air pump 53, and the self-cleaning suction tube 54 to move laterally, so that the quality improvement component 5 can move synchronously with the laser cutting head 4. During cutting, the quality improvement component 5 is activated. The extension and retraction of the hydraulic cylinder 523's telescopic rod drives the air pump 53, connecting pipe, annular filter shell 52, and protective cover 51 to rise and fall via the lifting frame 533. The protective cover 51 is adjusted to a suitable distance above the metal sheet (note that the protective cover 51 should not be in contact with the metal sheet). After the air pump 53 starts, the air inside the protective cover 51 and the contaminants from the cutting process are drawn into the initial pipe 55, and then enter the annular filter shell 52 through the connecting pipe 56. At the same time as the air pump 53 starts, the air filter 512 starts simultaneously. The compressed clean air is divided into low-temperature airflow and high-temperature airflow through the vortex pipe 516. The low-temperature airflow enters the inflation pipe 513 through two corrugated telescopic pipes 517, and the high-temperature airflow is discharged through the hot air end. The low-temperature airflow in the inflation pipe 513 enters the annular pipe 514 through the hose and is then introduced through the air intake. The air inlet 518 blows into the connecting pipe 56, driving the first fan blade 515 to rotate, which in turn drives the rotating ring 57 and the hollow connecting frame 58 to rotate. Then, the two scraper blades 59 rotate in the initial pipe 55 and the connecting pipe 56 respectively, continuously scraping the inner walls of both. This scrapes off the molten slag and metal particles adhering to the inner walls of the initial pipe 55 and the connecting pipe 56 during the process of removing contaminants, effectively preventing pipe blockage, maintaining dust collection efficiency, reducing contamination of the plate surface, optical lenses and machine tool moving parts, and improving the overall cutting quality. At the same time, the low-temperature gas entering the connecting pipe 56 through the air inlet 518 will cool down the contaminants passing through the connecting pipe 56, thereby reducing their adhesion ability and preventing contaminants from sticking to the filter screen 526 and clogging the mesh. The air filling pipe 513 fills the small ring pipe 520 with low-temperature gas through the pipe, and then sprays it around the cutting area through the slag spray nozzle to blow away the molten slag. The pollutants scraped off and cooled by the scraper 59 will enter the annular filter housing 52 in the direction of airflow. After being filtered by the filter screen 526, the gas will be discharged through the exhaust pipe. The pollutants will fall into the area of ​​the annular filter housing 52 containing water. When the airflow passes through the connecting pipe, it will drive the second fan blade 530 to rotate, which in turn drives the rotating rod 527 and the stirring blade 529 to rotate. The rotating stirring blade 529 will mix the pollutants into the water and wet them, preventing the pollutants from being sucked up again by suction later. At the same time, the rotating rod 527 will drive the crossbar 532 to rotate. When the crossbar 532 passes the protruding rod 528, it will push the protruding rod 528, causing the protruding rod 528 to drive the rubber tapping head 531 to deflect upward around the rotating connection point. Then, under its own weight, the rubber tapping head 531 will fall back and tap the filter screen 526, causing the filter screen 526 to vibrate and clear the filter screen 526 to prevent blockage, ensuring airflow and dust collection efficiency.

[0028] If a small amount of contaminants remains in the connecting pipe 56 later, and the air pump 53 has stopped running, the contaminants will slide along the inclined inner wall of the connecting pipe 56 through the external threaded discharge port 510 into the internal threaded transparent collection box 511 for unified collection. Later, the internal threaded transparent collection box 511 can be unscrewed to pour out the contaminants. Similarly, the slag discharge port can be opened by rotating the threaded sealing cap to discharge the contaminants inside the annular filter shell 52. After cleaning, the threaded sealing cap can be screwed on, and a certain amount of water can be added to the annular filter shell 52.

[0029] The above description is merely a preferred embodiment of the present invention and is illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present invention, all of which will fall within the protection scope of the present invention.
