Description

Technical Field

[0001] This application relates to the field of surface anti-corrosion treatment of neodymium iron boron magnets, and in particular to a surface anti-corrosion treatment device for processing neodymium iron boron magnets. Background Technology

[0002] When NdFeB magnets are exposed to air, they react with oxygen to form a NdFeB oxide layer. This thin film thickens over time, leading to severe surface corrosion and affecting their lifespan. Furthermore, contact with most strong acids or alkalis directly causes black powdery deposits, and contact with certain reagents results in a dusty residue. The neodymium element in NdFeB magnets is highly chemically reactive and readily reacts with other substances, especially in humid environments where corrosion is more likely. To remove surface contaminants, form a protective film, and improve corrosion resistance, NdFeB magnets need to be immersed in or sprayed with a passivation solution for a period of time to form a passivation film.

[0003] In existing NdFeB magnets, during passivation treatment, the baskets containing the NdFeB magnets are stacked in a lifting frame, with the bottom of the top basket in contact with the NdFeB magnets placed in the bottom basket. This can easily affect the full reaction between the NdFeB magnets and the passivation solution in the pool. Utility Model Content

[0004] In order to load and unload storage bins containing NdFeB magnets and to increase the contact area between NdFeB magnets and passivation liquid, this application provides a surface anti-corrosion treatment device for processing NdFeB magnets.

[0005] This application provides a surface corrosion protection device for processing neodymium iron boron magnets, which adopts the following technical solution:

[0006] A surface anti-corrosion treatment device for processing neodymium iron boron magnets includes a pool body. Two lifting mechanisms are symmetrically fixedly installed on the side wall of the pool body. A connecting plate is fixed on the lifting mechanism, and a storage mechanism is installed on the connecting plate. The storage mechanism includes a box and a locking rod. The box body is fixedly installed between the two connecting plates. Two sets of locking rods and support rods are fixedly connected to the box body. Two sets of storage bins are equidistantly engaged between the locking rods, support rods, and box body. The storage bins are provided with through grooves, and a pad is fixedly installed on the box body.

[0007] By adopting the above technical solution, the two sets of storage bins are snapped together between the clamping rod and the support rod, and the storage bins can be installed inside the box body.

[0008] Optionally, the storage bin is connected to the interior of the box body via a through groove, and the box body is connected to the interior of the pool body.

[0009] By adopting the above technical solution, the passivation solution flows through the channel into the storage tank, which can increase the contact area between the neodymium iron boron magnet and the passivation solution.

[0010] Optionally, the storage bin is slidably connected to the clamping rod and the support rod, and the bottom of one set of storage bins contacts the pad.

[0011] By adopting the above technical solution, the pad supports a group of storage bins, allowing the storage bins to be stored in the box body.

[0012] Optionally, the lifting mechanism includes a clamping plate and a column. The clamping plate and the column are fixedly connected to the side wall of the pool. A hydraulic rod is fixedly installed inside the column. A connecting plate is fixedly installed at the telescopic end of the hydraulic rod. A sliding groove is provided on the column. An inlet pipe is connected to the pool.

[0013] By adopting the above technical solution, the passivation solution can be discharged into the pool through the liquid inlet pipe, thereby allowing the passivation solution to fully contact the neodymium iron boron magnet.

[0014] Optionally, the two columns are symmetrically arranged on the side wall of the pool, and the columns are engaged with the card plate.

[0015] By adopting the above technical solution, the hydraulic rod drives the connecting plate to slide inside the column, which can cause the connecting plate to move the box body.

[0016] Optionally, the inlet pipe is fixedly connected to the pool body, and a connecting plate is slidably installed on the chute.

[0017] By adopting the above technical solution, the chute limits the connecting plate, allowing the tank to slide out of the pool.

[0018] Optionally, the connecting plate is slidably connected to the column, and the connecting plate contacts the top of the pool body.

[0019] By adopting the above technical solution, when the bottom end of the connecting plate contacts the top end of the pool, the storage tank placed inside the tank can be immersed in the passivation solution.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] When the lifting mechanism drives the connecting plate to slide away from the pool body, the connecting plate can drive the box body out of the pool body, and the storage boxes containing neodymium iron boron magnets can be placed into the box body in sequence. Since two sets of clamping rods and support rods are fixedly installed on the box body, the clamping rods and support rods limit the storage boxes, which allows the operator to quickly load and unload the storage boxes. In addition, there is a gap between the two sets of storage boxes, which can prevent the end of the storage box from contacting the neodymium iron boron magnets, which is conducive to increasing the contact area between the passivation liquid and the neodymium iron boron magnets in the pool body.

[0022] The side wall of the storage box is provided with several through grooves. The passivation liquid in the pool flows into the storage box through the through grooves, which can improve the passivation effect of the NdFeB magnet and help the NdFeB magnet form a passivation film.

[0031] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0032] This application discloses a surface anti-corrosion treatment device for processing neodymium iron boron magnets. (Refer to...) Figure 6 , Figure 7 A surface anti-corrosion treatment device for processing neodymium iron boron magnets includes a pool body 1. Two lifting mechanisms 2 are symmetrically fixedly installed on the side wall of the pool body 1. A connecting plate 3 is fixed on the lifting mechanism 2, and a storage mechanism 4 is installed on the connecting plate 3.

[0033] When the user places several storage bins 404 between the clamping rod 402 and the support rod 403 in sequence, the pad 406 can support a group of storage bins 404 at the bottom, which makes it easier to install the storage bins 404 into the inside of the box 401.

[0034] The storage bin 404 is connected to the interior of the box body 401 through the through groove 405, and the box body 401 is connected to the interior of the pool body 1.

[0035] After the user installs the storage box 404 into the box 401, the passivation liquid in the pool 1 can flow into the storage box 404 through the channel 405, thereby increasing the contact area between the neodymium iron boron magnet and the passivation liquid.

[0036] The storage bin 404 is slidably connected to the clamping rod 402 and the support rod 403, and the bottom of a set of storage bins 404 contacts the pad 406.

[0037] A gap is left between the two sets of storage bins 404, which can improve the passivation effect of neodymium iron boron magnets.

[0038] Reference Figure 3 , Figure 4 as well as Figure 5 The lifting mechanism 2 includes a clamping plate 201 and a column 202. The clamping plate 201 and the column 202 are fixedly connected to the side wall of the pool body 1. A hydraulic rod 205 is fixedly installed inside the column 202. A connecting plate 3 is fixedly installed at the telescopic end of the hydraulic rod 205. A sliding groove 204 is provided on the column 202. An inlet pipe 203 is connected to the pool body 1.

[0039] When the hydraulic rod 205 is activated inside the column 202, its telescopic end can drive the connecting plate 3 to move in the slide groove 204, thereby causing the connecting plate 3 to drive the box 401 to slide out of the pool body 1, thus facilitating the loading and unloading of materials in the storage box 404.

[0040] Reference Figure 4 , Figure 5 Two uprights 202 are symmetrically arranged on the side wall of the pool body 1, and the uprights 202 are engaged with the card plate 201.

[0041] Two uprights 202 are installed on both sides of the pool body 1, which can limit the connection plate 3. Then, the box body 401 can be slid in the pool body 1 through the connection plate 3, and the height of the box body 401 can be adjusted.

[0042] Reference Figure 1 , Figure 3 The liquid inlet pipe 203 is fixedly connected to the pool body 1, and the connecting plate 3 is slidably installed on the chute 204.

[0043] The passivation solution can be discharged into the interior of the pool 1 through the liquid inlet pipe 203, thereby immersing the neodymium iron boron magnet in the passivation solution in the pool 1.

[0044] Reference Figure 2 , Figure 3 as well as Figure 5 The connecting plate 3 is slidably connected to the column 202, and the connecting plate 3 is in contact with the top of the pool body 1.

[0045] When the bottom end of the connecting plate 3 contacts the top end of the pool body 1, it can support the box body 401, thereby placing the box body 401 inside the pool body 1.

[0046] This application discloses a surface anti-corrosion treatment device for processing neodymium iron boron magnets. The implementation principle is as follows: When the lifting mechanism 2 drives the connecting plate 3 to slide away from the pool body 1, the connecting plate 3 can cause the box 401 to slide out of the pool body 1. The storage box 404 containing neodymium iron boron magnets is then placed into the box 401. Since two sets of locking rods 402 and support rods 403 are fixedly installed on the box 401, the locking rods 402 and support rods 403 limit the movement of the storage box 404. This design allows operators to quickly load and unload materials from the storage bins 404. The gap between the two sets of storage bins 404 prevents the ends of the storage bins 404 from contacting the NdFeB magnets, thus increasing the contact area between the passivation liquid and the NdFeB magnets in the pool 1. Several through-slots 405 are provided on the sidewalls of the storage bins 404, allowing the passivation liquid in the pool 1 to flow into the storage bins 404, thereby improving the passivation effect of the NdFeB magnets and facilitating the formation of a passivation film on the NdFeB magnets.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
