Technical Field

[0001] This utility model belongs to the field of neodymium iron boron processing technology, specifically relating to a device for neodymium iron boron surface coating processing. Background Technology

[0002] Neodymium iron boron (NdFeB) magnets are, simply put, a type of magnet that differs from ordinary magnets in that they are known as the "king of magnets" due to their superior magnetic properties. NdFeB contains a large amount of the rare earth element neodymium, as well as iron and boron, and is characterized by its hardness and brittleness. Because its surface is extremely susceptible to oxidation and corrosion, NdFeB magnets require surface coating treatment.

[0003] The patent, with announcement number CN221297044U and titled "A Novel Neodymium Iron Boron Permanent Magnet Vacuum Magnetron Coating Machine," discloses a vacuum coating machine body. The machine body has a dual-motor drive transmission assembly fixedly connected to its inner bottom, and a carrier plate is placed on the dual-motor drive transmission assembly. The magnet to be coated is placed on the upper part of the carrier plate. The carrier plate and vacuum valve are aligned and matched. The machine operates by using two motors to drive the conveyor belt, which in turn moves the carrier plate left and right. Because the machine uses fewer drive electrical components, it effectively reduces operating costs and achieves the effect of a dual-motor drive transmission mechanism.

[0004] However, the existing technical problem or defect is that the coating operation can only be carried out on one side of the neodymium iron boron magnet placed on the carrier plate, which is inefficient and not conducive to large-scale coating operations. Therefore, based on the above defects, the applicant has proposed a better technical solution to solve the above-mentioned technical problems.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example

[0029] like Figures 1 to 4 As shown, a device for surface coating of neodymium iron boron includes a housing 1 and a magnetron sputtering target 2 disposed within the housing 1; it also includes a support plate 3, a coating mechanism 4 and a drive mechanism 5. The support plate 3 is slidably disposed within the housing 1, and a plurality of square cavities 31 are formed on the support plate 3. The coating mechanism 4 is rotatably connected within the square cavities 31. A sealing plate 6 is provided at the front end of the support plate 3, and the drive mechanism 5 is disposed on the front end face of the sealing plate 6 and is connected to the coating mechanism 4.

[0030] This utility model employs multiple coating processing mechanisms 4 built into the housing 1 and utilizes the rotational connection between the two to facilitate double-sided coating of the neodymium iron boron magnets 200 on the coating processing mechanism 4. Compared with conventional techniques that can only coat one side, the work efficiency is greatly improved, making it easy to use for large-scale coating operations.

[0031] In this embodiment, please refer to Figures 2-4The square cavity 31 is provided with three spaced-apart. The coating processing mechanism 4 includes a substrate 41 and a cover plate 42. The substrate 41 is rotatably connected to the square cavity 31 via a rotating shaft 100. The substrate 41 is provided with multiple through holes 411. The lower end of the through hole 411 is provided with a boss 412. The cover plate 42 is attached to the substrate 41 and is provided with through holes 421 corresponding to the through holes 411.

[0032] The through-hole 411 and the boss 412 form a space for accommodating the neodymium iron boron magnet 200. The arrangement of multiple through-holes 411 facilitates the application of coating operations for large batches of neodymium iron boron magnets 200. The size of the through-hole 421 is smaller than the size of the neodymium iron boron magnet 200, so that the cover plate 42 can be used to limit the neodymium iron boron magnet 200 within the through-hole 411. The cover plate 42 can be fixed to the substrate 41 by detachable components such as fastening bolts. In specific operation, the neodymium iron boron magnet 200 is placed on the boss 412 within the through-hole 411, and then the cover plate 42 is attached to the substrate 41 to limit the neodymium iron boron magnet 200 within it.

[0033] In this embodiment, please refer to the return. Figure 1 and Figure 2 The drive mechanism 5 includes a drive motor 51 and two sets of pulleys 52. Near the sealing plate 6, a receiving slot 32 is provided on the support plate 3. The rotating shaft 100 passes through the receiving slot 32 and is rotatably connected to the sealing plate 6. The drive motor 51 is located on the front end face of the sealing plate 6, and its output end is connected to a rotating shaft 100. A set of pulleys 52 is connected between two adjacent rotating shafts 100. In this example, the size of the sealing plate 6 is adapted to the size of the cavity inside the housing 1, which makes it convenient to use the sealing plate 6 to enclose multiple coating processing mechanisms 4 in the housing 1 for efficient coating operations, and at the same time, it is convenient to protect the drive motor 51.

[0034] During operation, the drive motor 51 rotates, driving one of the coating processing mechanisms 4 to rotate, which in turn drives the other two coating processing mechanisms 4 to rotate using two sets of pulleys 52. During the rotation of the coating processing mechanism 4, the neodymium iron boron magnet 200 on the coating processing mechanism 4 can be coated on both sides using the magnetron sputtering target 2. The operation is simple and convenient, improving work efficiency.

[0035] In this embodiment, a protective cover 7 is provided on the drive motor 51; the protective cover 7 can further protect the drive motor 51 from the coating effect; there are three magnetron sputtering targets 2, and the three magnetron sputtering targets 2 are respectively set to correspond to the three square cavities 31; one magnetron sputtering target 2 corresponds to one coating processing mechanism 4, which facilitates the improvement of coating efficiency and effect; the front end face of the sealing plate 6 is provided with a push-pull member 8; the push-pull member 8 facilitates the push-pull of the sealing plate 6, and better removes or places the support plate 3 into the housing 1, thereby completing the coating or disassembly operation of the neodymium iron boron magnet 200.

[0036] The working principle of this utility model:

[0037] This utility model provides a device for surface coating of neodymium iron boron magnets. In specific use, the neodymium iron boron magnet 200 is placed on the boss 412 in the through hole 411, and then the cover plate 42 is attached to the substrate 41 to limit the neodymium iron boron magnet 200 therein.

[0038] The sealing plate 6 and the support plate 3 are pushed into the housing 1 by the push-pull component 8, and the housing 1 is completely closed (the housing 1 is provided with a cavity door). The drive motor 51 drives one of the coating processing mechanisms 4 to rotate, thereby using two sets of pulleys 52 to drive the other two coating processing mechanisms 4 to rotate. During the rotation of the coating processing mechanism 4, the neodymium iron boron magnet 200 on the coating processing mechanism 4 can be coated on both sides by the magnetron sputtering target 2.

[0039] After coating is completed, pull out the support plate 3 and remove the cover plate 42 to take out the neodymium iron boron magnet 200.

[0040] The above description is a detailed description of the preferred embodiments of the present utility model. However, the embodiments are not intended to limit the scope of the patent application of the present utility model. All equivalent changes or modifications made under the technical spirit of the present utility model should fall within the patent scope covered by the present utility model.
