Description

Technical Field

[0001] This utility model relates to the field of surface anti-corrosion treatment technology for bonded NdFeB magnets, specifically a surface anti-corrosion treatment device for bonded NdFeB magnets. Background Technology

[0002] Bonded NdFeB magnets are made by mixing rapidly quenched NdFeB magnetic powder and a binder through compression molding or injection molding. Bonded magnets offer high dimensional accuracy, allowing for the fabrication of relatively complex magnetic components. They also feature one-time molding and multi-pole orientation. However, due to the poor corrosion resistance of rare earth elements and their alloys, and the fact that the NdFeB microstructure consists of at least two phases—a NdFeB-rich phase at grain boundaries and main grains—the galvanic corrosion caused by the difference in electrode potential accelerates the corrosion process. To improve the corrosion resistance of NdFeB magnet surfaces, extensive work has been done on its microstructure or by modifying its composition. However, to date, surface coating protection technology remains the most effective method.

[0003] Currently, surface corrosion protection of bonded NdFeB magnets is usually achieved by spraying. However, in existing technologies, the bonded NdFeB magnets are usually held in a clamp and rotated for spraying. During the spraying process, the contact surface between the clamp and the bonded NdFeB magnet is often not sprayed, resulting in incomplete spraying and poor corrosion protection of the bonded NdFeB magnets. Therefore, it is necessary to propose a surface corrosion protection device for bonded NdFeB magnets. Utility Model Content

[0004] To overcome the shortcomings of existing technologies and solve the problem of poor corrosion resistance caused by incomplete coating of bonded NdFeB magnets, this utility model proposes a surface anti-corrosion treatment device for bonded NdFeB magnets.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a surface anti-corrosion treatment device for bonding neodymium iron boron magnets, including an operating table, with support plates fixedly connected to both sides of the top of the operating table, a flipping mechanism movably installed on the top of the support plate, a bracket fixedly connected to one side of the top of the operating table, a linear motor fixedly connected to the top of the bracket, a rotary spraying machine fixedly connected to the sliding end of the linear motor, and a magnetic block slidably connected to the inner side of the support plate;

[0006] The flipping mechanism includes a flipping table, which is fixedly connected to the top of the support plate. Both sides of the top of the flipping table are provided with ramps. A rotating rod is rotatably connected to the middle of the top of the flipping table. A flipping rod is fixedly connected to the outer wall of the rotating rod. One end of the rotating rod passes through the flipping table and is fixedly connected to a connecting rod. One end of the connecting rod is slidably connected to a guide rod. A cylinder is movably installed at one end of the guide rod.

[0007] Preferably, the top of the flipping table has symmetrical slots on both sides, which are engaged with the flipping rod for locking.

[0008] Preferably, one end of the connecting rod is provided with a guide groove, one end of the guide rod is slidably connected to the inside of the guide groove, and one end of the guide rod is fixedly connected to a connecting sleeve.

[0009] Preferably, the cylinder is fixedly connected to the top of the operating table, and the cylinder telescopic shaft is fixedly connected to one end of the connecting sleeve.

[0010] Preferably, a fixed plate is fixedly connected to the opposite side of the support plate, a lifting plate is slidably connected to the opposite side of the fixed plate, and magnetic blocks are fixedly connected to both sides of the top of the lifting plate.

[0011] Preferably, both ends of the lifting plate are fixedly connected to sliders, and the fixed plate has a sliding groove on the opposite side. The slider is slidably connected inside the sliding groove, and a positioning rod is fixedly connected to the inner wall of the sliding groove. The positioning rod passes through the slider and is slidably connected to the slider.

[0012] Preferably, a fixed sleeve is fixedly connected to the top of the operating platform, a screw is rotatably connected to the inner cavity of the fixed sleeve, a threaded sleeve is threadedly connected to the outer wall of the screw, a transmission rod is rotatably connected to the top of the threaded sleeve, and one end of the transmission rod is rotatably connected to the bottom of the lifting plate.

[0013] The advantages of this utility model are:

[0014] This invention involves placing a bonded NdFeB magnet on an inclined plate on one side of a flipping table. A magnetic block on the bottom of the flipping table attracts the bonded NdFeB magnet, ensuring its stable placement on the slope. A linear motor on a support drives a rotary sprayer to slide laterally back and forth, while the sprayer rotates and coats the entire upper surface of the bonded NdFeB magnet. Then, a flipping mechanism flips the bonded NdFeB magnet to one side. A cylinder pushes a guide rod to move, which in turn causes a connecting rod to swing. The connecting rod then drives a rotating rod to rotate, which in turn drives a flipping rod to rotate. The rotation of the flipping rod then... The bonded NdFeB magnets on the flipping table are flipped from one inclined plane to the other. The magnetic blocks on both sides of the bottom of the flipping table have opposite polarities, and the magnetic blocks on the other side continue to attract the bonded NdFeB magnets, thus achieving the effect of flipping one side of the bonded NdFeB magnets. The lower surface of the bonded NdFeB magnets is then fully sprayed using a rotary sprayer. During the spraying of the upper and lower surfaces, the surface of the bonded NdFeB magnets is not obstructed, thus achieving a more comprehensive spraying effect and solving the problem of poor corrosion resistance caused by incomplete spraying of bonded NdFeB magnets.

[0022] 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 scope of protection of the present utility model.

[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0024] This application discloses a surface anti-corrosion treatment device for bonding neodymium iron boron magnets. (Refer to...) Figures 1-5A surface anti-corrosion treatment device for bonded NdFeB magnets includes an operating table 1. Support plates 2 are fixedly connected to both sides of the top of the operating table 1. A flipping mechanism 3 is movably mounted on the top of the support plates 2. A bracket 4 is fixedly connected to one side of the top of the operating table 1. A linear motor 41 is fixedly connected to the top of the bracket 4. A rotary sprayer 42 is fixedly connected to the sliding end of the linear motor 41. A magnetic block 5 is slidably connected to the inner side of the support plates 2. By placing the bonded NdFeB magnets on the flipping table 31, the linear motor 41 on the bracket 4 drives the rotary sprayer 42 to reciprocate laterally. The rotary sprayer 42 rotates and performs spraying operations. The rotating mechanism 3 and two magnetic blocks 5 work together to flip the bonded NdFeB magnet to one side. The magnetic blocks 5 on both sides have opposite polarities. Utilizing the principle of like poles repelling and unlike poles attracting, the bonded NdFeB magnet can be stably flipped to one side. The rotary sprayer 42 is then used for spraying, thereby achieving a comprehensive spraying effect. The rotary sprayer 42 is existing technology. Its principle is to spray the paint onto the surface of the object being sprayed using a high-pressure airflow, thereby achieving the purpose of coating. At the same time, this sprayer is also equipped with an automatic rotation function, which can automatically rotate the object being sprayed during spraying, thereby achieving a comprehensive and uniform spraying effect.

[0025] The flipping mechanism 3 includes a flipping table 31, which is fixedly connected to the top of the support plate 2. Both sides of the top of the flipping table 31 are provided with ramps 32. A rotating rod 33 is rotatably connected to the middle of the top of the flipping table 31. A flipping rod 34 is fixedly connected to the outer wall of the rotating rod 33. One end of the rotating rod 33 passes through the flipping table 31 and is fixedly connected to a connecting rod 36. One end of the connecting rod 36 is slidably connected to a guide rod 38. A cylinder 310 is movably installed at one end of the guide rod 38. The cylinder 310 drives the guide rod 38 to move, the guide rod 38 drives the connecting rod 36 to swing, the connecting rod 36 drives the rotating rod 33 to rotate, and the rotating rod 33 drives the flipping rod 34 to rotate, so that the flipping rod 34 can drive the bonded neodymium iron boron magnet to flip from one side of the ramp 32 to the other side of the ramp 32.

[0026] Reference Figure 1 , Figure 4 and Figure 5 The top of the tilting table 31 has symmetrical slots 35 on both sides, which are engaged with the tilting rod 34. One end of the connecting rod 36 has a guide groove 37, and one end of the guide rod 38 is slidably connected to the inside of the guide groove 37. One end of the guide rod 38 is fixedly connected to the connecting sleeve 39. The cylinder 310 is fixedly connected to the top of the operating table 1, and the telescopic shaft of the cylinder 310 is fixedly connected to one end of the connecting sleeve 39. The tilting rod 34 is suspended so that one side of the tilting rod 34 is just locked inside the slot 35, making the surface of the slope 32 flat. The telescopic shaft of the cylinder 310 drives the guide rod 38 to move through the connecting sleeve 39. When the guide rod 38 moves, it drives the connecting rod 36 to swing through the guide groove 37, so that the connecting rod 36 can swing back and forth stably.

[0027] Reference Figure 2 and Figure 3 A fixed plate 53 is fixedly connected to the opposite side of the support plate 2. A lifting plate 51 is slidably connected to the opposite side of the fixed plate 53. Magnetic blocks 5 are fixedly connected to both sides of the top of the lifting plate 51. Slider blocks 52 are fixedly connected to both ends of the lifting plate 51. A sliding groove 54 is opened on the opposite side of the fixed plate 53. The slider 52 is slidably connected inside the sliding groove 54. A positioning rod 55 is fixedly connected to the inner wall of the sliding groove 54. The positioning rod 55 passes through the slider 52 and is slidably connected to the slider 52. A fixed sleeve 56 is fixedly connected to the top of the operating table 1. A screw 57 is rotatably connected to the inner cavity of the fixed sleeve 56. A threaded sleeve 58 is threadedly connected to the outer wall of the screw 57. A transmission rod 59 is rotatably connected to the top of the threaded sleeve 58. One end of the transmission rod 59 is rotatably connected to the bottom of the lifting plate 51. By rotating the screw 57 inside the fixed sleeve 56, the screw 57 rotates, causing the threaded sleeve 58 to slide. The sliding of the threaded sleeve 58 drives one end of the transmission rod 59 to move. The other end of the transmission rod 59 pushes the lifting plate 51 to move up and down. The magnetic block 5 moves up and down with the lifting plate 51, so that the magnetic force between the magnetic block 5 and the bonded neodymium iron boron magnet can be easily adjusted. When the lifting plate 51 moves up and down, it drives the slider 52 to slide in the groove 54 of the fixed plate 53. The positioning rod 55 makes the slider 52 slide stably.

[0028] Working principle: During use, the operating table 1 is placed stably, and the bonded NdFeB magnet is placed on the flipping table 31 of the flipping mechanism 3. The support plate 2 stably supports the flipping table 31. The flipping rod 34 on one side is engaged in the slot 35 on the same side, making the ramp 32 flat. The magnetic block 5 attracts the bonded NdFeB magnet on the ramp 32 and places it stably. By rotating the screw 57 in the inner cavity of the rotating fixed sleeve 56, the screw 57 drives the threaded sleeve 58 to slide and push the transmission rod 59. One end of the transmission rod 59 pushes the lifting plate 51 up and down, so that the magnetic force between the magnetic block 5 and the bonded NdFeB magnet can be adjusted. When the lifting plate 51 rises and falls, the slider 52 slides in the groove 54 of the fixed plate 53. The positioning rod 55 makes the slider 52 slide. Stable sliding allows the lifting plate 51 to rise and fall stably. The linear motor 41 on the bracket 4 drives the rotary sprayer 42 to reciprocate laterally. The rotary sprayer 42 moves back and forth and performs rotary spraying operations, thereby spraying the entire surface of the bonded NdFeB magnet. The cylinder 310 drives the connecting sleeve 39 to move, and the sliding sleeve drives the guide rod 38 to move. The guide rod 38 drives the connecting rod 36 to swing through the guide groove 37. The connecting rod 36 drives the rotating rod 33 to rotate. The rotating rod 33 drives the two sets of flipping rods 34 to rotate simultaneously, so that the bonded NdFeB magnet flips from one side of the slope 32 to the other side of the slope 32. The rotary sprayer 42 is used again to spray the entire surface, thereby achieving the effect of full spraying.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
