Description

Technical Field

[0002] NdFeB is simply a kind of magnet. Different from the magnets we usually see, it is called "King of Magnets" because of its excellent magnetic properties. NdFeB contains a large amount of rare earth element neodymium, as well as iron and boron. It is hard and brittle. Since the surface is easily oxidized and corroded, NdFeB must be treated with surface coating. Surface chemical passivation is one of the good solutions. However, the processing of NdFeB in the existing technology has the following defects: In the prior art, before the NdFeB processing device performs surface treatment on the NdFeB, it is necessary to clean both sides of the NdFeB to remove impurities such as grease, oxides, and dust on the surface of the NdFeB. After processing one side, the NdFeB needs to be turned over manually to process the other side, which is very inconvenient. In the prior art, during the flipping process of the NdFeB, the flipping assembly in the NdFeB processing device has limited limiting effect on the NdFeB, which can easily cause the NdFeB to move; and the flipping assembly has limited effect on clamping and fixing the NdFeB, which can easily cause the NdFeB to move downward when cleaning the surface of the NdFeB, thereby affecting the effect of cleaning the surface of the NdFeB.

[0033] An integrated NdFeB processing technology comprises the following steps: S1: Surface cleaning, the NdFeB needs to be thoroughly cleaned to remove grease, oxides, dust and other impurities on the surface of the NdFeB; and the surface of the NdFeB is jet-dried to further remove grease, oxides, dust and other impurities on the surface of the NdFeB, thereby improving the electroplating effect of the NdFeB; S2: Pickling treatment, pickling treatment is carried out to further remove oxides and impurities on the surface of NdFeB and improve the adhesion of the electroplating layer; pickling usually uses acidic solutions such as sulfuric acid and hydrochloric acid, and the pickling time and temperature need to be strictly controlled; S3: Electroplating process, electroplating copper and nickel layers on the surface of NdFeB. The copper layer is usually used as the bottom layer to improve the conductivity of the substrate and enhance the bonding force between the subsequent coating and the NdFeB substrate; the nickel layer is used to increase the wear resistance and corrosion resistance of the NdFeB material; S4: Cleaning. After the electroplating is completed, the NdFeB needs to be thoroughly cleaned to remove the residual plating solution and treatment agent. Cleaning is usually carried out with clean water or deionized water, and the cleaning time and temperature need to be controlled. S5: Passivation treatment. In order to further improve the corrosion resistance of the surface of NdFeB, passivation treatment can be carried out. Passivation treatment can be achieved by chemical or electrochemical methods to form a dense passivation film to prevent corrosion by corrosive media. S6: Drying and packaging. The NdFeB after cleaning and passivation is dried and packaged in a dry and clean environment to prevent it from being contaminated and corroded again.

[0034] Specific use of the present invention: First, the staff places the NdFeB on the first transmission mechanism 12, and the first transmission mechanism 12 is started to drive the NdFeB to move into the box 10. The NdFeB enters the box 10 and contacts the two limit blocks 16, so that under the guidance of the two limit blocks 16, the NdFeB moves in the center and moves to the upper side of the support plate 15. The control system controls the extension of the hydraulic telescopic rod 14, and the extension of the hydraulic telescopic rod 14 drives the support plate 15 and the NdFeB to move upward, so that the NdFeB enters the frame 23. The control system controls the two second stepper motors 49 to start, and the two second stepper motors 49 start to drive the two double-threaded screws 50 to rotate. The two ends of the double-threaded screw 50 are respectively in threaded contact with one end of the two slides 24, and the external threads at the two ends of the double-threaded screw 50 are in opposite directions, so that the rotation of the double-threaded screw 50 can drive the two slides 24 to move closer to or away from each other.

[0035] The two double-threaded screw rods 50 rotate to drive the two slide plates 24 to approach each other, and the two slide plates 24 approach to each other to drive the two movable frames 25 and the first clamping blocks 28 to approach each other, and the two first clamping blocks 28 approach to each other to drive the two first rubber plates 32 and the first hollow elastic member 33 to approach each other, thereby clamping and fixing the opposite sides of the NdFeB. The opposite sides of the NdFeB are respectively entered into the two first V-shaped grooves 31, so as to clamp and fix the opposite sides of the NdFeB and limit the upper and lower positions.

[0036] Secondly, the two slide plates 24 and the movable frame 25 continue to approach each other, and the two first clamping blocks 28 are supported by the NdFeB, so that the two pressing plates 26 slide in the two movable frames 25 respectively, and the two pressing plates 26 slide to squeeze the solutions in the two movable frames 25 into the two round tubes 27 respectively, and the solutions in the two round tubes 27 respectively enter the two pairs of first water bags 29. Each pair of first water bags 29 expands and pushes the two first clamping plates 30 to move, and the two first clamping plates 30 move to squeeze the upper and lower sides of the first rubber plate 32, so as to improve the upper and lower limit effect on the opposite sides of the NdFeB.

[0037] At the same time, the two slide plates 24 and the movable frame 25 continue to approach each other and cooperate with the two first clamping blocks 28 to be resisted by the NdFeB, so that the distance between the movable frame 25 and the first clamping block 28 is reduced, and the movable frame 25 moves to squeeze the two second hollow elastic members 37, and the two second hollow elastic members 37 are squeezed and deformed to generate elastic force, and the two second hollow elastic members 37 are deformed to make the solutions in the two second hollow elastic members 37 enter the two second hydraulic chambers 57 respectively. The solution in the two second hydraulic chambers 57 pushes the two piston plates 38 to approach each other, and the two piston plates 38 approach each other to drive the two L-shaped rods 36 and the second clamping blocks 39 to approach each other, and the two second clamping blocks 39 approach each other to drive the two elastic blocks 43 and the second rubber plate 44 to approach each other, thereby clamping and fixing the other two opposite sides of the NdFeB. And the other two opposite sides of the NdFeB enter the two second V-shaped grooves 42 respectively, so as to clamp and fix the other two opposite sides of the NdFeB and limit the upper and lower positions. The two piston plates 38 approach each other to compress the first spring 35 to generate elastic force, so that the two piston plates 38 can be reset away from each other under the elastic force of the first spring 35. The movable frame 25 moves to squeeze and deform the second hollow elastic member 37 to generate elastic force, so that the movable frame 25 and the first clamping block 28 can be reset away from each other under the elastic force of the two second hollow elastic members 37.

[0038] At the same time, the two pairs of piston plates 38 are close to each other to allow the solutions in the two first hydraulic chambers 34 to enter the two first hollow elastic members 33 respectively, which is conducive to improving the clamping and fixing effect of the two first hollow elastic members 33 on the opposite sides of the NdFeB. In order to clamp and fix the NdFeB in multiple directions and limit the upper and lower positions, the NdFeB is prevented from being displaced in the flip assembly, which is conducive to improving the cleaning efficiency of the two end faces of the NdFeB.

[0039] At the same time, the two second clamping blocks 39 approach each other and drive the two push rods 46 to approach each other. One end of the push rod 46 slides with the inclined surface of one side of the guide block 47, so that the two push rods 46 approach the second clamping block 39 under the guidance of the guide block 47. The two push rods 46 approach the second clamping block 39, and the other end of the push rod 46 slides with the inclined surface of one end of the T-shaped slider 40, pushing the two T-shaped sliders 40 to move. The movement of the two T-shaped sliders 40 drives the two second clamping plates 41 to move. The movement of the two second clamping plates 41 squeezes the upper and lower sides of the second rubber plate 44, so as to improve the upper and lower limit effect of the other opposite sides of the neodymium iron boron. Thereby, the upper and lower limit effects of the neodymium iron boron in multiple directions are improved, and the stable horizontal movement and flipping of the neodymium iron boron are promoted, so as to improve the cleaning efficiency of the two end faces of the neodymium iron boron.

The frame 23 moves horizontally to drive the NdFeB to move to the bottom of the cleaning box 17. Several first spray valves 18 spray the cleaning liquid in the cleaning box 17 to clean the surface of one end face of the NdFeB. The control system controls the first stepper motor 48 to start, and the first stepper motor 48 starts to drive the frame 23 to rotate, and the frame 23 rotates to drive the NdFeB to turn over, so that the cleaning liquid in the cleaning box 17 is sprayed out through several first spray valves 18 to clean the other end face of the NdFeB, thereby improving the efficiency of cleaning the two end faces of the NdFeB, so as to remove impurities such as grease, oxides, dust, etc. on the surface of the NdFeB.
