Description

Technical Field

[0001] The present invention relates to the technical field of NdFeB alloy processing equipment, in particular to a NdFeB alloy surface protective coating coating device. Background Art

[0002] Neodymium iron boron magnet alloy is a tetragonal crystal formed by neodymium, iron and boron. Electroplating is the process of plating a thin layer of other metals or alloys on certain metal surfaces using the principle of electrolysis. Neodymium magnets are electroplated after production to improve their working performance and corrosion resistance, and enhance the protective performance of the surface of neodymium iron boron alloy.

[0003] The patent name is: A NdFeB surface electroplating treatment equipment (patent application number: 202121400252.5), which discloses a NdFeB surface electroplating treatment equipment. Technical problem: Provide a NdFeB surface electroplating treatment equipment that is simple to operate and saves time and effort. The technical solution is: A NdFeB surface electroplating treatment equipment, including a cleaning tank, a drain pipe, a reaction tank, a fixing mechanism and a clamping mechanism, which is provided with a cleaning tank and a reaction tank, a drain pipe is provided between the cleaning tank and the top of the reaction tank, which is provided with a fixing mechanism, and a clamping mechanism is provided on the fixing mechanism. Through the cooperation between the fixing mechanism and the clamping mechanism, the NdFeB can be clamped, and the NdFeB can be transported, so that the NdFeB is cleaned first, and then the NdFeB is electroplated after cleaning.

[0004] In the above case, a clamping mechanism is used to clamp a single NdFeB, and then clamp it for subsequent cleaning and electroplating operations. Only a single NdFeB can be electroplated at a time, which reduces the efficiency of the device in electroplating NdFeB. In addition, the clamping mechanism will block the outside of the NdFeB, which can easily cause uneven electroplating of the NdFeB, thereby reducing the quality of the NdFeB electroplating. Therefore, it is necessary to propose a NdFeB alloy surface protective coating coating device to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a NdFeB alloy surface protective coating coating device to solve the problem that the existing electroplating equipment proposed in the above background technology uses a clamping mechanism to clamp a single NdFeB during use, and then performs subsequent cleaning and electroplating operations. Only a single NdFeB can be electroplated at a time, thereby reducing the efficiency of the device in electroplating NdFeB.

[0006] To achieve the above object, the present invention provides the following technical solution: a device for applying a protective coating to a surface of a NdFeB alloy, comprising a reaction tank, a rotating sleeve being rotatably connected to the top of the reaction tank, and a placement component being provided inside the reaction tank;

[0007] The placement assembly includes a positioning block, a mesh box, a limit block and a placement plate;

[0008] Among them, one end of the positioning block is fixedly connected to the outside of the mesh box, a limiting groove is opened inside the mesh box, the inside of the limiting groove is slidingly connected to the outside of the limiting block, and the outside of the limiting block is fixedly connected to the outside of the placement plate.

[0009] Preferably, a positioning groove is provided inside the rotating sleeve, and the positioning groove is slidably connected to the positioning block.

[0010] Preferably, the top of the placement plate is fixedly connected to a support rod, and the top end of the support rod is fixedly connected to a support plate.

[0011] Preferably, the number of the placement plates is three, and all three placement plates are located inside the mesh box.

[0012] Preferably, a driving assembly is provided on the outside of the reaction tank, and the driving assembly includes a fixing plate, a driving motor and a driving gear;

[0013] The side of the fixing plate is fixedly connected to the outside of the reaction tank, the top of the fixing plate is fixedly connected to the bottom of the driving motor, and the top of the output shaft of the driving motor is fixedly connected to the bottom of the driving gear.

[0014] Preferably, the outside of the rotating sleeve is fixedly connected to a driven gear, and the side surface of the driving gear is meshed with the side surface of the driven gear.

[0015] Preferably, an auxiliary component is provided on the outside of the mesh box, and the auxiliary component includes a rotating plate, a connecting plate, a rotating shaft and fan blades. The outside of the rotating plate is fixedly connected to the outside of the mesh box, and the inner wall of the rotating plate is fixedly connected to the outside of the connecting plate. The inside of the connecting plate is rotatably connected to the outside of the rotating shaft, and the outside of the rotating shaft is fixedly connected to the inside of the fan blades.

[0016] Preferably, there are multiple rotating plates, and the multiple rotating plates are obliquely arranged outside the mesh box.

[0017] The technical effects and advantages of the present invention are as follows:

[0018] 1. By setting up the placement component, multiple NdFeB alloys can be placed inside the mesh box during the electroplating of NdFeB alloys. At the same time, the NdFeB alloys can be placed in layers using the placement plate, thus avoiding the accumulation of NdFeB alloys and improving the efficiency of the NdFeB alloy electroplating process.

[0019] 2. By setting up the driving component, when the NdFeB alloy is electroplated, the driving motor can be turned on, and the driving motor will drive the driven gear to rotate through the driving gear, and the driven gear will drive the mesh box to rotate through the rotating sleeve. The mesh box will drive the NdFeB alloy placed on the top of the placement plate to move, so that the electrolyte can be evenly adhered to the surface of the NdFeB alloy, thereby improving the electroplating quality of the NdFeB alloy;

[0020] 3. By setting up auxiliary components, when the driving component drives the mesh box to rotate, the mesh box will drive the rotating plate to rotate. Since multiple rotating plates are tilted on the outside of the mesh box, the tilted rotating plates will divert the electroplating liquid inside the reaction tank during rotation, so that the electroplating liquid can flush the NdFeB alloy through the mesh holes of the mesh box, thereby further improving the efficiency of the electroplating treatment of the NdFeB alloy; in addition, the rotating plate will stir and mix the electrolyte liquid inside the reaction tank, and at the same time, the fan blades will rotate under the rotation of the rotating plate, thereby increasing the stirring force of the electrolyte liquid at the bottom of the reaction tank, preventing the electrolyte liquid at the bottom of the reaction tank from precipitating, improving the mixing quality of the electrolyte liquid, and thus improving the adhesion effect of the NdFeB alloy.

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.

[0027] The present invention provides Figures 1-4 The shown device is a surface protective coating coating device for a neodymium iron boron alloy, comprising a reaction tank 1, a rotating sleeve 2 being rotatably connected to the top of the reaction tank 1, and a placement assembly being arranged inside the reaction tank 1, the placement assembly comprising a positioning block 3, a mesh box 4, a limit block 5 and a placement plate 7, wherein one end of the positioning block 3 is fixedly connected to the outside of the mesh box 4, a limit groove 6 is provided inside the mesh box 4, the inside of the limit groove 6 is slidably connected to the outside of the limit block 5, the outside of the limit block 5 is fixedly connected to the outside of the placement plate 7, a positioning groove is provided inside the rotating sleeve 2, and the positioning groove is slidably connected to the positioning block 3. When electroplating the NdFeB alloy, multiple NdFeB alloys can be placed inside the mesh box 4, which is convenient for electroplating the NdFeB alloy in batches. At the same time, when the electroplating treatment is completed, the positioning block 3 can be pulled upward to separate the positioning block 3 from the positioning groove provided inside the rotating sleeve 2. The mesh box 4 can be quickly separated from the reaction tank 1, which is convenient for quickly discharging the NdFeB alloys after the electroplating treatment, thereby improving the efficiency of the NdFeB alloy electroplating treatment.

[0028] In addition, the top of the placement plate 7 is fixedly connected to a support rod 8, and the top of the support rod 8 is fixedly connected to a support plate 9. There are three placement plates 7, and all three placement plates 7 are located inside the mesh box 4. The placement plates 7 can be used to place the NdFeB alloy in layers, avoiding the accumulation of the NdFeB alloy and improving the quality of the NdFeB alloy electroplating.

[0029] Then, a drive assembly is provided on the outside of the reaction tank 1. The drive assembly includes a fixed plate 11, a drive motor 12, and a driving gear 13. The side of the fixed plate 11 is fixedly connected to the outside of the reaction tank 1, and the top of the fixed plate 11 is fixedly connected to the bottom of the drive motor 12. The top of the output shaft of the drive motor 12 is fixedly connected to the bottom of the driving gear 13. The outside of the rotating sleeve 2 is fixedly connected to a driven gear 10, and the side of the driving gear 13 is meshed with the side of the driven gear 10. When the drive motor 12 is turned on, the drive motor 12 will drive the driven gear 10 to rotate through the driving gear 13. The driven gear 10 will drive the mesh box 4 to rotate through the rotating sleeve 2. The mesh box 4 will drive the NdFeB alloy placed on the top of the placement plate 7 to move, so that the electrolyte can be evenly attached to the surface of the NdFeB alloy, thereby improving the electroplating quality of the NdFeB alloy.

[0030] Finally, an auxiliary component is provided on the outside of the mesh box 4, which includes a rotating plate 14, a connecting plate 15, a rotating shaft 16 and a fan blade 17.

There are multiple rotating plates 14, and multiple rotating plates 14 are obliquely arranged on the outside of the mesh box 4. When the driving component drives the mesh box 4 to rotate, the mesh box 4 will drive the rotating plate 14 to rotate. Since multiple rotating plates 14 are tiltedly arranged on the outside of the mesh box 4, the tilted rotating plate 14 will divert the electroplating liquid inside the reaction tank 1 during rotation, so that the electroplating liquid can flush the NdFeB alloy through the mesh holes of the mesh box 4, thereby further improving the efficiency of the electroplating treatment of the NdFeB alloy; in addition, the rotating plate 14 will stir and mix the electrolyte liquid inside the reaction tank 1, and at the same time, the fan blades 17 will rotate under the rotation of the rotating plate 14, thereby increasing the stirring force of the electrolyte liquid at the bottom of the reaction tank 1, preventing the electrolyte liquid at the bottom of the reaction tank 1 from precipitating, improving the mixing quality of the electrolyte liquid, and thus improving the adhesion effect of the NdFeB alloy.

[0031] Working principle: When electroplating NdFeB alloy, multiple NdFeB alloys can be placed inside the mesh box 4, which is convenient for electroplating NdFeB alloy in batches. At the same time, when the electroplating is completed, the positioning block 3 can be pulled upward to separate the positioning block 3 from the positioning groove provided in the rotating sleeve 2, and the mesh box 4 can be quickly separated from the reaction tank 1, which is convenient for quickly discharging the NdFeB alloys after the electroplating treatment, thereby improving the efficiency of the electroplating treatment of NdFeB alloy. At the same time, the placement plate 7 can be used to place the NdFeB alloy in layers, avoiding the accumulation of NdFeB alloy and improving the quality of the electroplating of NdFeB alloy. When the drive motor 12 is turned on, the drive motor 12 will drive the driven gear 10 to rotate through the driving gear 13, and the driven gear 10 will drive the mesh box 4 to rotate through the rotating sleeve 2, and the mesh box 4 will drive the NdFeB alloy placed on the top of the placement plate 7 to The rotating plate 14 is arranged on the outside of the mesh box 4 at an angle, and the inclined rotating plate 14 guides the electroplating liquid inside the reaction tank 1 during rotation, so that the electroplating liquid flushes the neodymium iron boron alloy through the mesh holes of the mesh box 4, thereby further improving the efficiency of the electroplating treatment of the neodymium iron boron alloy; in addition, the rotating plate 14 stirs and mixes the electrolyte liquid inside the reaction tank 1, and the fan blades 17 rotate under the rotation of the rotating plate 14, thereby increasing the stirring force of the electrolyte liquid at the bottom of the reaction tank 1, preventing the electrolyte liquid at the bottom of the reaction tank 1 from precipitating, improving the mixing quality of the electrolyte liquid, and thus improving the adhesion effect of the neodymium iron boron alloy.
