Description

Technical Field

[0001] This utility model relates to the field of neodymium iron boron magnet technology, specifically to a high-efficiency electroplating device for neodymium iron boron magnets. Background Technology

[0002] Neodymium magnets, also known as neodymium iron boron magnets, are tetragonal crystals formed from neodymium, iron, and boron. These magnets are the second strongest permanent magnets in terms of magnetic properties after holmium magnets at absolute zero, and are also the most commonly used rare-earth magnets. Neodymium iron boron permanent magnets have excellent magnetic properties and are widely used in electronics, electrical machinery, medical devices, toys, packaging, hardware machinery, aerospace and other fields. Common applications include permanent magnet motors, loudspeakers, magnetic separators, computer disk drives, and magnetic resonance imaging equipment.

[0003] In existing devices, NdFeB magnets are kept stationary during electroplating, which results in poor electroplating performance. Furthermore, after electroplating is completed and the magnets are separated from the plating solution, plating solution residue remains on the surface. If this residue remains, impurities can easily form after drying, affecting the magnets' performance.

[0004] To address this, a high-efficiency electroplating device for neodymium iron boron magnets is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a high-efficiency electroplating device for neodymium iron boron magnets to solve the above-mentioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A high-efficiency electroplating device for neodymium iron boron magnets includes a storage tank, a support frame, a cylinder, a drive mechanism, a clamping block, a shaking mechanism, and a connecting block. The cylinder is mounted on the top of the support frame. The drive mechanism is connected to the cylinder, the clamping block is connected to the drive mechanism, the shaking mechanism is connected to the drive mechanism, and the connecting block is connected to the shaking mechanism. When the cylinder controls the drive mechanism to run, the clamping block lowers the neodymium iron boron magnet into the storage tank for electroplating. When the drive mechanism controls the clamping block to rise, the shaking mechanism controls the connecting block to shake off excess electroplating solution from the neodymium iron boron magnet.

[0008] Preferably, the driving mechanism includes a horizontal plate, a forward and reverse lead screw, a spur gear, a rack, and a threaded block. The horizontal plate is installed at the output end of the cylinder, the forward and reverse lead screw is installed inside the horizontal plate, the spur gear is installed at one end of the forward and reverse lead screw, the rack engages with the spur gear, the threaded block is connected to the forward and reverse lead screw, and the clamping block is installed at the bottom end of the threaded block.

[0009] Preferably, the positive and negative lead screws have two symmetrically arranged threads, and the length values ​​of the two threads on the positive and negative lead screws are consistent with the length value of the rack.

[0010] Preferably, the shaking mechanism includes a vertical rod, a connecting sleeve, a spring, and a push rod. The vertical rod is connected to the support frame, the connecting sleeve is installed at one end of the vertical rod, the spring is installed inside the connecting sleeve, the push rod is connected to the spring, and the connecting block is installed at one end of the horizontal plate, and the connecting block cooperates with the push rod.

[0011] Preferably, the end of the push rod that connects to the connecting block is provided with an arc-shaped portion, and the arc-shaped portions are symmetrically arranged.

[0012] Preferably, the connecting block includes a steep section and a gentle section, the connection between the steep section and the gentle section is arc-shaped, the steep section is located at the top of the connecting block, and the gentle section is located at the bottom of the connecting block.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. By controlling the lifting and lowering of the horizontal plate to achieve the lifting and lowering of the NdFeB magnet, it is possible to control the immersion of the NdFeB magnet in the electroplating solution, clamp the NdFeB magnet before immersion in the electroplating solution, and control the NdFeB magnet to vibrate after immersion in the electroplating solution, which can improve the electroplating effect of the NdFeB magnet.

[0015] 2. After the NdFeB magnet electroplating is completed, it rises and can vibrate by hitting the horizontal plate with the push rod. This can shake off the residual electroplating solution on the NdFeB magnet, ensuring the uniform distribution of electroplating solution on the NdFeB magnet and avoiding local excess electroplating solution that may produce impurities.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. However, the embodiments described below are only some embodiments of the present utility model, and not all of them. If other embodiments are obtained by those skilled in the art without creative effort, they shall fall within the protection scope of the present utility model.

[0022] Reference Figures 1 to 3 A high-efficiency electroplating device for neodymium iron boron magnets includes a storage tank 1, a support frame 2, a cylinder 3, a drive mechanism 4, a clamping block 5, a vibrating mechanism 6, and a connecting block 7. The cylinder 3 is mounted on the top of the support frame 2, and the drive mechanism 4 is connected to the cylinder 3. The cylinder 3 controls the operation of the drive mechanism 4. The clamping block 5 is connected to the drive mechanism 4, and the drive mechanism 4 controls the movement of the clamping block 5 to clamp the neodymium iron boron magnet. The vibrating mechanism 6 is connected to the drive mechanism 4, and the connecting block 7 is connected to the vibrating mechanism 6. After the neodymium iron boron magnet is detached from the electroplating solution by the cylinder 3, it can generate a knocking motion to produce vibration, thereby vibrating the neodymium iron boron magnet. The residual electroplating solution on the surface of the magnet is shaken off. The connecting block 7 includes a steep part 71 and a gentle part 72. The connection between the steep part 71 and the gentle part 72 is arc-shaped. The steep part 71 is located at the top of the connecting block 7, and the gentle part 72 is located at the bottom of the connecting block 7. With the above arrangement, the push rod 64 can be raised and lowered smoothly. At the same time, the push rod 64 can be squeezed to retract into the connecting sleeve 62. When the cylinder 3 controls the drive mechanism 4 to run, the clamping block 5 drives the neodymium iron boron magnet to descend into the liquid storage tank 1 for electroplating. When the drive mechanism 4 controls the clamping block 5 to rise, the shaking mechanism 6 controls the connecting block 7 to shake off the excess electroplating solution on the neodymium iron boron magnet.

[0023] As one embodiment of this utility model, refer to Figure 2 and Figure 3The drive mechanism 4 includes a horizontal plate 41, a forward and reverse lead screw 42, a spur gear 43, a rack 44, and a threaded block 45. The horizontal plate 41 is installed at the output end of the cylinder 3. The cylinder 3 controls the lifting and lowering of the horizontal plate 41, and under the action of the clamping block 5, it can drive the neodymium iron boron magnet to lift and lower, thus realizing the electroplating of the neodymium iron boron magnet. The forward and reverse lead screw 42 is installed inside the horizontal plate 41, and the spur gear 43 is installed at one end of the forward and reverse lead screw 42. The rack 44 cooperates with the spur gear 43. The threaded block 45 is connected to the forward and reverse lead screw 42, and the clamping block 5 is installed at the bottom of the threaded block 45. At the end, the positive and negative lead screws 42 can drive the clamping block 5 to clamp the neodymium iron boron magnet under the action of the threaded block 45. There are two symmetrical threads on the positive and negative lead screws 42, and the length of the two threads on the positive and negative lead screws 42 is consistent with the length of the rack 44. Through the above settings, the minimum distance between the two clamping blocks 5 can be set, so that the neodymium iron boron magnet can be completely clamped at the moment it enters the electroplating solution, thereby avoiding the neodymium iron boron magnet from shaking during electroplating and improving the stability of the neodymium iron boron magnet electroplating.

[0024] As one embodiment of this utility model, refer to Figures 2 to 4 The vibration mechanism 6 includes a vertical rod 61, a connecting sleeve 62, a spring 63, and a push rod 64. The vertical rod 61 is connected to the support frame 2 and extends into the storage tank 1. This configuration ensures that the NdFeB magnet vibrates when immersed in the electroplating solution, thereby improving the electroplating effect. The connecting sleeve 62 is installed at one end of the vertical rod 61, the spring 63 is installed inside the connecting sleeve 62, and the push rod 64 is connected to the spring 63. A connecting block 7 is installed at one end of the horizontal plate 41 and cooperates with the push rod 64. The end of the push rod 64 connected to the connecting block 7 has an arc-shaped portion 65. This configuration allows the horizontal plate 41 to drive the connecting block 7 to rise. When the NdFeB magnet descends, it is pressed against the push rod 64, which is then retracted into the connecting sleeve 62. After the pressure is released, the push rod 64 strikes the horizontal plate 41 under the action of the spring 63. The arc-shaped part 65 is symmetrically arranged, and the center line of the connecting block 7 coincides with the center line of the horizontal plate 41. The distance between the two ends of the connecting block 7 and the two ends of the horizontal plate 41 is greater than the height of the push rod 64. With the above arrangement, the push rod 64 can strike the horizontal plate 41 to generate vibration whether the NdFeB magnet is rising or falling. The vibration generated when the NdFeB magnet is falling can improve the electroplating effect of the NdFeB magnet, while the vibration generated when the NdFeB magnet is rising can shake off the electroplating liquid attached to the NdFeB magnet.

[0025] Working Principle: During use, the user places the NdFeB magnet between two clamping blocks 5, then activates cylinder 3. Cylinder 3 lowers the crossbar, which in turn rotates the spur gear 43. The spur gear 43 meshes with the rack 44, further rotating it. This rotation of the spur gear 43 then rotates the lead screw 42, which in turn moves two threaded blocks 45 in opposite directions. The movement of the threaded blocks 45 moves the clamping blocks 5, clamping the NdFeB magnet. Under the action of cylinder 3, the NdFeB magnet continues to descend, immersing itself in the electroplating solution for electroplating. After electroplating is complete... The cylinder 3 controls the horizontal plate 41 to rise. When the horizontal plate 41 rises, it can drive the neodymium iron boron magnet to rise synchronously and detach from the electroplating solution. When the horizontal plate 41 rises, it can drive the connecting block 7 to rise. When the connecting block 7 rises, it can squeeze the push rod 64 through the buffer section 72. When the push rod 64 is squeezed, it can squeeze the spring 63. When the push rod 64 moves to the steep section 71, the push rod 64 will hit the horizontal plate 41 under the action of the spring 63, thereby making the horizontal plate 41 vibrate and vibrate the neodymium iron boron magnet. This can shake off the residual electroplating solution on the neodymium iron boron magnet. At the same time, it can control the spur gear 43 to mesh with the rack 44 and control the two threaded blocks 45 to move in opposite directions to loosen the neodymium iron boron magnet, making it easier to collect the neodymium iron boron magnet.
