Description

Technical Field

[0001] This invention belongs to the field of laser cleaning technology, and specifically relates to a continuous treatment device for the surface of neodymium iron boron magnets. Background Technology

[0002] Neodymium iron boron (NdFeB) magnets are a high-performance rare-earth permanent magnet material with extremely high magnetic energy product and coercivity. The maximum magnetic energy product of NdFeB magnets can reach 52 MGOe (megagauss-Oersted), which is the highest among commercial permanent magnets currently available.

[0003] To remove residue, rust, and burrs from the surface of NdFeB magnets, laser treatment is commonly used. Laser rust removal (laser cleaning) refers to the process of using the high energy and high concentration of a laser to irradiate the workpiece. This causes the surface deposits (dirt, scale, rust, organic coatings, etc.) to absorb the laser energy, melting, vaporizing, or instantly expanding due to heat and being carried away by the vapor, thus achieving the purpose of cleaning the workpiece surface.

[0004] Existing technology requires that neodymium iron boron magnets be neatly arranged on a support plate before laser treatment, and burrs be removed by irradiating the magnets with a laser. However, when a high-energy laser beam is focused on the magnet surface, the residue or burrs on the magnet surface are rapidly heated, expanded, and splashed, causing molten slag to sputter onto nearby cleaned magnets. Specifically, smaller residues gain more kinetic energy during heating, resulting in a longer sputtering distance and making them more likely to sputter onto distant magnets; while larger molten slag gains less kinetic energy during heating, resulting in a shorter sputtering distance and making it more likely to sputter onto nearby magnets.

[0005] Although existing laser cleaning processes are equipped with inert gas to remove slag through inert gas purging, the effect of inert gas purging is limited for large volumes of molten slag, and it cannot effectively remove large volumes of molten slag that have sputtered onto nearby magnets. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of the prior art by providing a continuous processing device for the surface of neodymium iron boron magnets, thereby solving the technical problems in the prior art.

[0007] The objective of this invention can be achieved through the following technical solution: a continuous processing device for the surface of neodymium iron boron magnets, comprising a laser cleaning mechanism and a feeding rack and a conveying rack respectively installed at the inlet and outlet ends of the laser cleaning mechanism. Both the feeding rack and the feeding rack are equipped with conveying rollers. The laser cleaning mechanism also has conveying rollers installed inside. The feeding rack feeds the base frame into the laser cleaning mechanism via the conveying rollers. A laser integrated component is installed inside the laser cleaning mechanism. Several supporting components are slidably installed inside the base frame. Each supporting component includes a slide table and magnetic metal parts installed inside the slide table. The bottom sides of the slide table... High magnetic block one and high magnetic block two are installed separately. A ventilation groove is opened in the magnetic metal part. A slide block is installed longitudinally in the ventilation groove. An electric disk is installed at the bottom of the magnetic metal part. A magnetic block is installed at the bottom of the slide block. The electric disk is energized and attracts the magnetic block. The bottom of the slide block is connected to a rack through an L-shaped rod. The two sides of high magnetic block one are rotatably connected to the slide table through gears. The rack meshes with the gears. Through air holes are opened on both sides of the slide table. The slide table is connected to the ventilation groove. Fins are installed inside the ventilation groove. The neodymium iron boron magnets are neatly arranged on the top of the slide table. The position of the magnets is fixed by attracting the magnetic metal part with the neodymium iron boron magnets.

[0008] As a further optimization or improvement of this solution, a sliding sleeve is installed on one side of the bottom of the slide table, and the second high magnetic block slides inside the sliding sleeve. A support rod is installed at the bottom of the slide, and a connecting rod is installed on the support rod. The other end of the connecting rod is connected to the second high magnetic block.

[0009] As a further optimization or improvement of this solution, through air holes are opened on both sides of the slide table, the slide table is connected to the ventilation slide groove, and fins are installed inside the ventilation slide groove.

[0010] As a further optimization or improvement of this solution, a rubber damping pad is installed on the top of the slide table; after the neodymium iron boron magnet is placed on the top of the slide table, the magnet attracts the magnetic metal parts, and the rubber damping pad is squeezed.

[0011] As a further optimization or improvement to this solution, exhaust holes are provided on both sides of the base frame, with the through-holes corresponding to the exhaust holes.

[0012] As a further optimization or improvement to this solution, a guide groove is provided on the side wall of the base frame, and the supporting component is slidably installed with the guide groove.

[0013] As a further optimization or improvement of this solution, side magnetic block two and side magnetic block one are respectively installed on the inner walls of both sides of the base frame. Side magnetic block two and side magnetic block one respectively attract and fix the support components close to the two side walls of the base frame.

[0014] The beneficial effects of this invention are:

[0015] (1) In this invention, the laser integrated component irradiates the magnets on the top of the support assembly one by one from right to left. After the laser integrated component irradiates the magnets on the first support assembly, the first high magnetic block in the first support assembly rotates 180 degrees, so that the first high magnetic block and the second high magnetic block have the same magnetic pole and generate a repulsive force, so that the first support assembly is pushed to the rightmost side of the base frame. The first support assembly moves away from the second support assembly by the repulsive force, separating the cleaned magnets from the uncleaned magnets. When the laser integrated component irradiates the magnets on the second support assembly, it can avoid large particles of residue from splashing onto the magnets on the first support assembly. If the magnets on the first support assembly splash onto small particles of residue, the air supply device in the laser integrated component will automatically blow away the small particles of residue on them, thereby effectively avoiding residue remaining on the cleaned magnets.

[0016] (2) As the laser cleaning work proceeds, the number of cleaned magnets and the supporting components that support them increases. By connecting multiple sets of supporting components magnetically, the impact resistance of the supporting components is improved. Secondly, the present invention uses a magnetic disk to attract magnetic blocks, which causes the slide to move down. The slide pushes the high magnetic block two to slide outward through the connecting rod, so that the high magnetic block two gradually approaches the high magnetic block one of the adjacent supporting components, thereby increasing the attraction between the supporting components, making the connection between the supporting components more secure, improving the stability of the supporting components, and preventing the supporting components from vibrating due to the impact of high-power airflow.

[0017] (3) During installation, after the neodymium iron boron magnet is placed on the top of the slide, the magnet attracts the magnetic metal parts, which compresses the rubber damping pad. The friction damping between the magnet and the rubber damping pad is increased by deforming the rubber damping pad, thereby improving the stability of the magnet and avoiding the displacement of the magnet caused by the impact of high-power airflow.

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.

[0034] See Figures 1-8A continuous surface treatment device for neodymium iron boron magnets includes a laser cleaning mechanism 1 and a feeding rack 4 and a conveying rack 2 respectively installed at the inlet and outlet ends of the laser cleaning mechanism 1. Both the feeding rack 2 and the feeding rack 4 are equipped with conveying roller groups 3. The laser cleaning mechanism 1 is also equipped with conveying roller groups 3. The feeding rack 4 feeds a base frame 6 into the laser cleaning mechanism 1 via the conveying roller groups 3. A laser integrated component 5 is installed inside the laser cleaning mechanism 1. Several supporting components 8 are slidably installed inside the base frame 6. Each supporting component 8 includes a slide table 801 and a magnetic metal component 803 installed inside the slide table 801. High magnetic block 1 813 and high magnetic block 2 817 are respectively installed on both sides of the bottom of the slide table 801. A ventilation groove 805 is formed inside the magnetic metal component 803, and a longitudinal sliding groove 805 is formed within the ventilation groove 805. A movable mounting slide 807 is provided. A magnetic disk 810 is mounted on the bottom of a magnetic metal part 803. A magnetic block 809 is mounted on the bottom of the slide 807. When the magnetic disk 810 is energized, it attracts the magnetic block 809. The bottom of the slide 807 is connected to a rack 812 via an L-shaped rod 811. A high-magnetic block 813 is rotatably connected to the slide table 801 on both sides via gears 814. The rack 812 meshes with the gears 814. Through-holes 804 are provided on both sides of the slide table 801. The slide table 801 is connected to a ventilation groove 805. Fins 806 are installed inside the ventilation groove 805. A return spring 808 is mounted on the slide 807 and is connected to the magnetic metal part 803. Neodymium iron boron magnets are neatly arranged on the top of the slide table 801, and their positions are fixed by attracting the magnetic metal part 803.

[0035] Specifically, a guide groove 9 is provided on the side wall of the base frame 6, and the supporting component 8 is slidably installed with the guide groove 9.

[0036] Problems with existing technology;

[0037] During the laser surface treatment of NdFeB magnets, slag or burrs on the magnet surface inevitably generate splashed slag, which easily sputters onto the treated magnet. Specifically, smaller slag particles gain more kinetic energy during heating, resulting in a longer sputtering distance and making them more likely to sputter onto distant magnets; while larger slag particles gain less kinetic energy during heating, resulting in a shorter sputtering distance and making them more likely to sputter onto nearby magnets. Although existing laser cleaning processes are equipped with inert gas for slag removal through inert gas purging, the purging effect is limited for large slag particles, and it is impossible to effectively remove large slag particles that have sputtered onto nearby magnets.

[0038] The solution of this invention;

[0039] It should be noted that the laser integrated component 5 has an internal gas supply device, which uses rare gas to purge small particles of residue sputtered onto the magnet.

[0040] See Figures 4-7 The base frame 6 is not filled with the supporting components 8, but a space is reserved inside the base frame 6. Before use, neodymium iron boron magnets are neatly arranged on the top of the slide table 801 until the top of each slide table 801 is filled with magnets. The current position of the magnet is fixed by the magnet adsorbing the magnetic metal parts 803.

[0041] The base frame 6 is placed on the feed rack 4, and the base frame 6 is sent into the laser cleaning mechanism 1 by the conveyor roller group 3 on the feed rack 4. The laser integrated component 5 irradiates the supporting components 8 inside the base frame 6 one by one to achieve laser cleaning.

[0042] by Figure 5 For example, let the rightmost support component 8 be the first support component 8, and so on from right to left; in the initial state, the highly magnetic block 813 on the first support component 8 and the highly magnetic block 817 on the second support component 8 attract each other, connecting the first support component 8 and the second support component 8; the same applies to the second support component 8 and the third support component 8, as... Figure 5 As shown, the supporting components 8 inside the base frame 6 are connected as a whole at this time.

[0043] Next, the laser assembly 5 irradiates the magnets on the top of the support assembly 8 one by one from right to left. After the laser assembly 5 has irradiated the magnets on the first support assembly 8, the electric disk 810 in the first support assembly 8 is energized. The electric disk 810 drives the rack 812 to move down through the adsorption slide 807. The rack 812 drives the high magnetic block 1 813 to rotate 180 degrees through the gear 814, so that the magnetic poles of the first high magnetic block 1 813 and the second high magnetic block 2 817 are the same and generate a repulsive force, so that the first support assembly 8 is pushed to the rightmost side of the base frame 6. Figure 6 As shown, the first support assembly 8 is connected to the base frame 6 by the attraction between the high magnetic block 817 in the first support assembly 8 and the side magnetic block 11. When the first support assembly 8 reaches the side wall of the base frame 6, the power disk 810 is de-energized and the magnetic poles of the high magnetic block 813 are restored.

[0044] Through the above-described process, after the magnets on the first support component 8 are cleaned, the first support component 8 moves away from the second support component 8 by repulsion. When the laser assembly 5 irradiates the magnets on the second support component 8, large particles of residue can be prevented from splashing onto the magnets on the first support component 8. If small particles of residue are splashed onto the magnets on the first support component 8, the air supply device inside the laser assembly 5 will automatically blow away the small particles of residue. By continuing the above operation, residue remaining on the cleaned magnets can be effectively avoided.

[0045] It should be noted that, in order to further secure the magnet, an electromagnetic chuck can be installed on the top of the magnetic metal part 803 to secure the magnet.

[0046] See Figures 8-10 A sliding sleeve 816 is installed on one side of the bottom of the slide table 801. The second high magnetic block 817 slides inside the sliding sleeve 816. A support rod is installed at the bottom of the slide seat 807. A connecting rod 815 is installed on the support rod. The other end of the connecting rod 815 is connected to the second high magnetic block 817.

[0047] Specifically, a rubber damping pad 802 is installed on the top of the slide table 801; after the neodymium iron boron magnet is placed on the top of the slide table 801, the magnet attracts the magnetic metal part 803, and the rubber damping pad 802 is squeezed.

[0048] It should be noted that in order to improve the removal efficiency of large molten slag particles on the magnet, the existing technology usually forcibly increases the inert gas purging power. The high-power airflow impacts the support component 8 and the magnet on the support component 8, causing the support component 8 to vibrate and the magnet to shift.

[0049] First, as the laser cleaning process proceeds, the number of cleaned magnets and the supporting components 8 that support them increases. By magnetically connecting multiple sets of supporting components 8, the impact resistance of the supporting components 8 is improved. Second, the present invention uses the magnetic disk 810 to attract the magnetic block 809, causing the slide 807 to move downward. The slide 807 pushes the second high magnetic block 817 to slide outward of the sliding sleeve 816 through the connecting rod 815, so that the second high magnetic block 817 gradually approaches the first high magnetic block 813 of the adjacent supporting component 8, thereby increasing the attraction between the supporting components 8, making the connection between the supporting components 8 more secure, improving the stability of the supporting components 8, and preventing the supporting components 8 from vibrating due to the impact of high-power airflow.

[0050] During installation, after the neodymium iron boron magnet is placed on the top of the slide table 801, the magnet attracts the magnetic metal part 803, causing the rubber damping pad 802 to be squeezed. The frictional damping between the magnet and the rubber damping pad 802 is increased by deforming the rubber damping pad 802, thereby improving the stability of the magnet and preventing the magnet from shifting due to the impact of high-power airflow.

[0051] See Figures 4-8 The slide table 801 has through air holes 804 on both sides, and the slide table 801 is connected to the ventilation slide groove 805. The ventilation slide groove 805 is equipped with fins 806.

[0052] Specifically, the base frame 6 has exhaust holes 7 on both sides, and the through air hole 804 corresponds to the exhaust hole 7.

[0053] It should be noted that when the laser integrated component 5 irradiates the magnet, the magnet temperature rises sharply and exceeds the Curie temperature (approximately 340°C to 460°C), causing the magnetic domain structure to be destroyed and the magnet's magnetism to be easily affected. Based on this, the present invention installs a magnetic metal component 803 on the slide table 801. The magnetic metal component 803 can be made of iron, which has a thermal conductivity of approximately 80 W / m·K, while the thermal conductivity of neodymium iron boron magnets is only 7.7 W / m·K. The magnetic metal component 803 quickly absorbs the heat from the magnet, thereby reducing the impact of high temperature on the magnet's magnetism.

[0054] Specifically, the air outlet of the internal air supply device of the laser integrated component 5 is set at an angle. During use, the gas can enter the ventilation groove 805 through the through air hole 804 on the side wall of the slide table 801. The fins 806 inside the magnetic metal component 803 carry the heat of the magnetic metal component 803, accelerating the cooling of the magnetic metal component 803.

[0055] See Figures 5-7 Side magnetic block 2 11 and side magnetic block 10 are respectively installed on the inner walls of both sides of the base frame 6. Side magnetic block 2 11 and side magnetic block 10 respectively attract and fix the support components 8 close to the two side walls of the base frame 6.

[0056] It should be noted that, with Figure 5 For example, let the rightmost support component 8 be the first support component 8, and so on from right to left; in the initial state, there is a reserved space between the first support component 8 and the base frame 6, each group of support components 8 is magnetically connected, and the last support component 8 is connected to the side magnetic block 10; after the laser processing is completed, the first support component 8 is connected to the side magnetic block 21, and a reserved space is left between the last support component 8 and the base frame 6.

[0057] The implementation principle of this invention is as follows:

[0058] Before use, neodymium iron boron magnets are neatly arranged on the top of the slide table 801 until each set of slide tables 801 is filled with magnets. The magnets are fixed in their current positions by adsorbing the magnetic metal parts 803. The base frame 6 is placed on the feed rack 4, and the base frame 6 is sent into the laser cleaning mechanism 1 by the conveyor roller group 3 on the feed rack 4. The laser integrated component 5 irradiates the supporting components 8 inside the base frame 6 one by one to achieve laser cleaning.

[0059] by Figure 5 For example, let the rightmost support component 8 be the first support component 8, and so on from right to left; in the initial state, the highly magnetic block 813 on the first support component 8 and the highly magnetic block 817 on the second support component 8 attract each other, connecting the first support component 8 and the second support component 8; the same applies to the second support component 8 and the third support component 8, as... Figure 5As shown, the supporting components 8 inside the base frame 6 are connected as a whole at this time.

[0060] Next, the laser assembly 5 irradiates the magnets on the top of the support assembly 8 one by one from right to left. After the laser assembly 5 has irradiated the magnets on the first support assembly 8, the electric disk 810 in the first support assembly 8 is energized. The electric disk 810 drives the rack 812 to move down through the adsorption slide 807. The rack 812 drives the high magnetic block 1 813 to rotate 180 degrees through the gear 814, so that the magnetic poles of the first high magnetic block 1 813 and the second high magnetic block 2 817 are the same and generate a repulsive force, so that the first support assembly 8 is pushed to the rightmost side of the base frame 6. Figure 6 As shown, the first support assembly 8 is connected to the base frame 6 by the attraction between the high magnetic block 817 in the first support assembly 8 and the side magnetic block 11. When the first support assembly 8 reaches the side wall of the base frame 6, the power disk 810 is de-energized and the magnetic poles of the high magnetic block 813 are restored.

[0061] Through the above-described process, after the magnets on the first support component 8 are cleaned, the first support component 8 moves away from the second support component 8 by repulsion. When the laser assembly 5 irradiates the magnets on the second support component 8, large particles of residue can be prevented from splashing onto the magnets on the first support component 8. If small particles of residue are splashed onto the magnets on the first support component 8, the air supply device inside the laser assembly 5 will automatically blow away the small particles of residue. By continuing the above operation, residue remaining on the cleaned magnets can be effectively avoided.

[0062] It should be noted that in order to improve the removal efficiency of large molten slag particles on the magnet, the existing technology usually forcibly increases the inert gas purging power. The high-power airflow impacts the support component 8 and the magnet on the support component 8, causing the support component 8 to vibrate and the magnet to shift.

[0063] First, as the laser cleaning process proceeds, the number of cleaned magnets and the supporting components 8 that support them increases. By magnetically connecting multiple sets of supporting components 8, the impact resistance of the supporting components 8 is improved. Second, the present invention uses the magnetic disk 810 to attract the magnetic block 809, causing the slide 807 to move downward. The slide 807 pushes the second high magnetic block 817 to slide outward of the sliding sleeve 816 through the connecting rod 815, so that the second high magnetic block 817 gradually approaches the first high magnetic block 813 of the adjacent supporting component 8, thereby increasing the attraction between the supporting components 8, making the connection between the supporting components 8 more secure, improving the stability of the supporting components 8, and preventing the supporting components 8 from vibrating due to the impact of high-power airflow.

[0064] During installation, after the neodymium iron boron magnet is placed on the top of the slide table 801, the magnet attracts the magnetic metal part 803, causing the rubber damping pad 802 to be squeezed. The frictional damping between the magnet and the rubber damping pad 802 is increased by deforming the rubber damping pad 802, thereby improving the stability of the magnet and preventing the magnet from shifting due to the impact of high-power airflow.

[0065] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
