[0002] NdFeB magnets have high chemical activity and are prone to oxidation corrosion in a humid aerobic environment. Oxidation corrosion will affect the appearance of NdFeB magnets and also cause the magnetism of NdFeB magnets to decrease. Therefore, during the processing of NdFeB magnets, the surface of NdFeB magnets will be treated with anti-corrosion.

[0003] At present, NdFeB magnets are usually placed in a tray, and then the tray is moved to the bottom of the nozzle by a moving mechanism. The nozzle sprays anti-corrosion coating onto the surface of the NdFeB magnets for surface anti-corrosion treatment. The NdFeB magnets are placed on the tray, so the bottom of the NdFeB magnets is in contact with the tray. The anti-corrosion coating cannot be sprayed to the contact position between the NdFeB magnets and the tray, resulting in the bottom of the NdFeB magnets being unable to be effectively treated, leaving an anti-corrosion blind spot, thereby affecting the anti-corrosion performance of the NdFeB magnets.

The rack 28 is connected to the front and rear sides of the upper part of the collection box 101. The ends of the two rotating blocks 16 that are away from each other are connected to the gear 29 through a one-way clutch. The gear 29 will mesh with the rack 28 during the movement to the left.

[0040] like Figure 12-Figure 15 As shown, the cleaning mechanism includes an ultrasonic cleaning machine 30, a guide rail 31, a sliding shaft 32 and a drying component. The ultrasonic cleaning machine 30 is installed on the right part of the frame 1, and the guide rails 31 are connected to the front and rear sides of the casing 2 by bolts. The right part of the guide rail 31 is V-shaped, and the two sides of the two rails 15 away from each other are connected to the sliding shafts 32.

[0043] The staff controls the extension of the telescopic rod of the first cylinder 4 to drive the moving frame 5 and the nozzle 6 to move forward, and then moves the nozzle 6 out of the casing 2, and then puts the NdFeB magnet into the first discharge trough 20. The thickness of the NdFeB magnet is twice as large as the height of the first discharge trough 20, so the upper half of the NdFeB magnet will be exposed outside the first discharge trough 20, and then controls the screw motor 13 to drive the moving block 14 to move to the left, and the moving block 14 drives the track 15 to move to the left, and the track 15 drives the first discharge plate 19 and the sliding shaft 32 to move to the left, thereby driving the NdFeB magnet to move to the left, and the sliding shaft 32 slides in the guide rail 31. When the sliding shaft 32 slides to the V-shaped position of the guide rail 31, the sliding shaft 32 will move downward along the guide rail 31, and the sliding shaft 32 drives The track 15 moves downward, and the track 15 drives the first unloading plate 19 to move downward, thereby driving the NdFeB magnet to move downward, and moving the NdFeB magnet into the ultrasonic cleaning machine 30, and the ultrasonic cleaning machine 30 cleans the NdFeB magnet. Then the sliding shaft 32 moves upward along the guide rail 31 to move the NdFeB magnet out of the ultrasonic cleaning machine 30, and then the first unloading plate 19 continues to move to the left, and the NdFeB magnet also continues to move to the left. The first unloading plate 19 passes through the silicone door curtain 36 on the right and moves between the two mounting frames 33. The heater 35 heats the air, and the fan 34 blows hot air onto the cleaned NdFeB magnet to dry the cleaned NdFeB magnet and remove moisture from the cleaned NdFeB magnet. The silicone door curtain 36 The baffle 37 can block the heat and reduce the speed of heat loss. Then the first discharge plate 19 passes through the silicone door curtain 36 on the left and moves away from between the two mounting frames 33 to move the NdFeB magnet to the bottom of the nozzle 6. At this time, the screw motor 13 is turned off, and then the telescopic rod of the first cylinder 4 is controlled to shorten, driving the movable frame 5 and the nozzle 6 to move backward. At the same time, the water pump 8 extracts the anti-corrosion paint in the box body 3 through the hard pipe 9, and sucks the anti-corrosion paint into the hose 10. The anti-corrosion paint will flow into the connecting pipe 7 and be sprayed out through the nozzle 6 and sprayed onto the NdFeB magnet to perform anti-corrosion treatment on the surface of the NdFeB magnet. The movable frame 5 is U-shaped, so that the movable frame 5 can avoid the track 15 and the guide rod 24 to prevent the movable frame 5 from colliding with the track 15 and the guide rod 24. , the bellows 26 can protect the spring 25 to prevent the anti-corrosion paint from floating onto the spring 25. After the spraying is completed, the telescopic rod of the first cylinder 4 is controlled to extend, driving the movable frame 5 and the nozzle 6 to move forward, and the nozzle 6 is moved out of the casing 2, and then the screw motor 13 is controlled to continue to run, so that the track 15 continues to move to the left, and the second slide shaft 21 and the gear 29 also continue to move to the left. The second slide shaft 21 will contact the inclined position on the right side of the flip frame 27 during the movement to the left, and then the second slide shaft 21 will move downward along the inclined position on the right side of the flip frame 27. The second slide shaft 21 drives the second discharge plate 22 to move downward, so that the second discharge plate 22 and the first discharge plate 19 are fitted together, and the upper half of the NdFeB magnet enters the second discharge trough 23.The second slide shaft 21 enters the receiving groove 17 on the upper side of the rotating block 16, the spring 25 is compressed, and the bellows 26 is shortened. When the second slide shaft 21 moves to the left to the horizontal position of the flip frame 27, the second slide shaft 21 moves to the left along the horizontal position of the flip frame 27. At this time, the second discharge plate 22 and the first discharge plate 19 are already fitted, the upper half of the NdFeB magnet has entered the second discharge groove 23, the second slide shaft 21 has entered the upper receiving groove 17, and the gear 29 will mesh with the rack 28 during the process of moving to the left, and then the gear 29 will move to the left. The gear 29 rolls on the rack 28, and the rotating block 16 is driven to rotate. The rotating block 16 drives the first slide shaft 18 and the second slide shaft 21 to rotate, thereby driving the first discharge plate 19 and the second discharge plate 22 to rotate, and the NdFeB magnet is turned over so that the other side of the NdFeB magnet can be sprayed with anti-corrosion paint. After the gear 29 moves to the left and the rack 28 is disengaged, the NdFeB magnet is just turned over. At this time, the control screw motor 13 drives the moving block 14 to move right, and the moving block 14 drives the first slide shaft 18, the first discharge plate 19, and the second slide shaft 21. The second unloading plate 22 and the gear 29 move to the right. The gear 29 will mesh with the rack 28 during the rightward movement. The gear 29 rolls on the rack 28, and the gear 29 will rotate in the opposite direction. Under the action of the one-way clutch, the gear 29 will not drive the rotating block 16 to rotate. When the first slide shaft 18 moves to the right to the inclined position on the right side of the flip frame 27, under the action of the spring 25, the first unloading plate 19 and the first slide shaft 18 will move upward, and the first slide shaft 18 will move upward along the inclined position on the right side of the flip frame 27. The first slide shaft 18 will move from The first slide shaft 18 will move to the upper part of the track 15, the bellows 26 will extend, the first discharge plate 19 and the second discharge plate 22 will continue to move to the right, and the NdFeB magnet will also continue to move to the right, and the NdFeB magnet will be moved to the bottom of the nozzle 6. The thickness of the NdFeB magnet is twice the height of the second discharge groove 23, so the lower half of the NdFeB magnet will be exposed outside the second discharge groove 23. Repeat the above operation, and spray the anti-corrosion coating on the other side of the NdFeB magnet to reduce the processing blind spot and improve the anti-corrosion performance of the NdFeB magnet.
