[0002] Neodymium magnets, also known as NdFeB magnets, are tetragonal crystals formed by neodymium, iron, and boron. Due to their excellent magnetic properties, NdFeB magnets are widely used in various electronic products, such as hard disks, mobile phones, headphones, and battery-powered tools. When processing the surface of NdFeB magnets, it is necessary to polish each surface of NdFeB to increase the purity of the infiltrated dysprosium.

DETAILED DESCRIPTION

[0028] Embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0029] A surface treatment device for NdFeB permanent magnet materials, such as Figure 1-Figure 5 As shown, it includes a base frame 1, a connecting frame 2, a mounting frame 3, a sliding table 4, a grinding belt group 5, a driving motor 6, a guide plate 7, a lifting mechanism and a front and rear side grinding mechanism. The top of the base frame 1 is connected to the connecting frame 2, and the top right side of the connecting frame 2 is connected to the mounting frame 3. The mounting frame 3 is slidably connected to the sliding tables 4 on both the upper and lower sides, and the two sliding tables 4 are both installed with a grinding belt group 5. The sliding table 4 is installed with a driving motor 6, and the output shaft of the driving motor 6 is connected to the transmission shaft of one of the grinding belt groups 5. The right side of the mounting frame 3 is connected to the guide plate 7, and the guide plate 7 is used to place the NdFeB and guide the movement of the NdFeB. The mounting frame 3 is provided with a lifting mechanism for driving the sliding table 4 to rise and fall and a front and rear side grinding mechanism for grinding the front and rear sides of the NdFeB.

[0030] like Figure 2 As shown, the lifting mechanism includes a connecting frame 81 and an electric push rod 82. The two sliding tables 4 are connected to the connecting frame 81. The top and bottom of the mounting frame 3 are installed with an electric push rod 82. The telescopic rod of the electric push rod 82 is connected to the connecting frame 81.

[0031] like Figure 4 and Figure 5As shown, the front and rear side grinding mechanism includes a bracket 91, a mounting platform 92, a cylinder 93, a grinding belt group 94, a drive motor 95, a support platform 96 and a transmission rod 97. The left side of the mounting frame 3 is connected to the bracket 91, and the mounting platform 92 is slidably connected to the front and rear sides of the bracket 91. A grinding belt group 94 is installed in the middle of the mounting platform 92. A drive motor 95 is installed on the mounting platform 92, and the output shaft of the drive motor 95 is connected to the transmission shaft of the grinding belt group 94. Cylinders 93 are installed on the front and rear sides of the top of the bracket 91, and the telescopic rod of the cylinder 93 is connected to the mounting platform 92 so that the cylinder 93 can drive the mounting platform 92 to move. The lower part of the mounting platform 92 is slidably connected to the support platform 96, and the support platform 96 is used to support the neodymium iron boron. The front and rear sides of the sliding platform 4 below are slidably connected to the transmission rod 97, and the transmission rod 97 is slidably connected to the support platform 96 below.

[0032] When the surface of the NdFeB needs to be processed, the present device can be used for processing. When in use, the NdFeB is first placed on the guide plate 7, and then the telescopic rod of the electric push rod 82 is controlled to retract to drive the two connecting frames 81 to approach each other. The two connecting frames 81 approaching each other will drive the two sliding tables 4 to approach each other, thereby driving the two grinding belt groups 5 to approach each other, so that the grinding belt group 5 can contact the NdFeB, and then the NdFeB is pushed into between the two grinding belt groups 5. At this time, the driving motor 6 can be controlled to operate to drive the grinding belt group 5 to rotate. The grinding belt group 5 can grind the top and bottom surfaces of the NdFeB when rotating, and at the same time push the NdFeB to move to transmit the NdFeB. When the NdFeB is transmitted to the bracket 91, the NdFeB will be located between the two grinding belt groups 5. Between the grinding belt groups 94, the support platform 96 will support the bottom of the NdFeB, and then control the driving motor 95 to drive the grinding belt group 94 to rotate. The grinding belt group 94 can grind the front and rear sides of the NdFeB when rotating. In this way, the device can be used to grind the NdFeB, and in the process of grinding, multiple different surfaces on the NdFeB can be grinded at the same time, and the grinding efficiency is higher. In the actual operation process, the cylinder 93 can be controlled to drive the mounting platform 92 to move according to the different sizes of the NdFeB to adjust the distance between the two grinding belt groups 94. When adjusting the height of the sliding table 4, the support platform 96 can also be driven to move by the transmission rod 97, so as to achieve the effect of automatically adjusting the height of the support platform 96.

[0033] like Figure 6As shown, it also includes a guiding mechanism, which includes a connecting rod 101, a guiding frame 102, an elastic member 103 and an electric belt transmission group 104. Two connecting rods 101 are slidably connected on both sides of the front and rear of the mounting frame 3. A guiding frame 102 is connected between the two connecting rods 101. An elastic member 103 is connected between the connecting rod 101 and the mounting frame 3. The elastic member 103 is a connecting spring. An electric belt transmission group 104 is installed on the guiding frame 102. The guiding frame 102 can guide the NdFeB. Controlling the operation of the electric belt transmission group 104 can assist in the transmission of the NdFeB.

[0034] When the NdFeB is placed, it is located between the two guide frames 102. At this time, both sides of the NdFeB will contact the electric belt conveyor group 104. At this time, the electric belt conveyor group 104 can be controlled to operate to assist in conveying the NdFeB. During the conveying process, the NdFeB will squeeze the two guide frames 102 away from each other until the distance between the two guide frames 102 is consistent with the width of the NdFeB. In this process, the elastic member 103 is compressed. In this way, the NdFeB can be guided by the guide frame 102 and can be conveyed by the rotation of the electric belt conveyor group 104.

[0035] like Figure 7-Figure 9 As shown, it also includes a conveying mechanism, which includes a conveying frame 111, a rotating wheel 112, a transmission rod 113, a transmission frame 114, a reduction motor 115, a worm 116 and a worm wheel 117. The upper parts of the two mounting platforms 92 are slidably connected to the transmission frame 114, and the lower part of the transmission frame 114 is connected to the conveying frame 111. The conveying frame 111 and the supporting platform 96 are evenly spaced and rotatably connected to multiple rotating wheels 112. The rotating wheels 112 can transport the NdFeB by rotating. The front and rear sides of the upper sliding platform 4 are connected to the transmission rod 113. 13, the two transmission rods 113 are respectively slidably connected with the two transmission frames 114, and when the transmission rods 113 move up and down, the transmission frames 114 can be driven to move up and down. The support platform 96 and the conveying frame 111 are both equipped with a reduction motor 115, and a worm 116 is connected to the output shaft of the reduction motor 115. A worm gear 117 is connected to the rotating wheel 112. The worm gear 117 and the worm 116 are meshed, so that the reduction motor 115 can drive the rotating wheel 112 to rotate through the worm 116 and the worm gear 117 when it is in operation, thereby transmitting the NdFeB.

[0036] When the NdFeB is located in the bracket 91, the upper and lower sides of the NdFeB are in contact with the rotating wheels 112 on the upper and lower sides respectively. At this time, the reduction motor 115 can be controlled to drive the worm 116 to rotate. The worm 116 drives the worm wheel 117 to rotate when rotating. The worm wheel 117 can drive the rotating wheel 112 to rotate when rotating. The rotation of the rotating wheel 112 assists in transporting the NdFeB. In this way, the NdFeB can be moved in the bracket 91 to realize the transmission of the NdFeB. When the upper sliding table 4 moves, the transmission frame 114 can be driven to move together through the transmission rod 113, so that the height of the conveying frame 111 can be adaptively adjusted.

[0037] like Fig.10 and Fig.11 As shown, it also includes a left and right side grinding mechanism, which includes a side frame 121, an electric belt conveyor group 122, a guide frame 123, a sliding shaft 128, a clamping plate 129, an elastic member 1210 and a grinding assembly. The left side of the connecting frame 2 is connected to the side frame 121, and the electric belt conveyor group 122 is installed on the side frame 121. A plurality of guide frames 123 are evenly spaced and connected to the electric belt conveyor group 122. The front and rear sides of the guide frame 123 are both slidably connected. A sliding shaft 128 is connected, and two upper and lower clamping plates 129 are slidably connected to the sliding shaft 128. The two clamping plates 129 on the same sliding shaft 128 are tilted outward on the side away from the side frame 121, and the two directions are away from each other, so that the neodymium iron boron can be guided. An elastic member 1210 is connected between the two clamping plates 129 on the same sliding shaft 128, and the elastic member 1210 is a reset spring. A grinding assembly is provided between the connecting frame 2 and the bracket 91.

[0038] like Fig.10 and Fig.11 As shown, the grinding assembly includes a guide rail 125, a screw 126, a grinding plate 127 and a grinding plate 124. The grinding plate 124 is connected to the left side of the connecting frame 2, and the guide rail 125 is connected to the middle of the upper left side of the bracket 91. The grinding plate 127 is slidably connected to the guide rail 125, and the screw 126 is rotatably connected to the guide rail 125. The screw 126 is threadedly matched with the grinding plate 127, so that the rotation of the screw 126 can drive the grinding plate 127 to move and adjust the position of the grinding plate 127.

[0039] After the front and rear sides of the NdFeB are polished, the NdFeB is transported to the left and can be transported between the upper and lower clamping plates 129. During the transportation process, the NdFeB will squeeze the two clamping plates 129 away from each other through the inclined part of the clamping plate 129, and the elastic member 1210 will be stretched. When the NdFeB is completely moved between the two clamping plates 129, the two clamping plates 129 can clamp the NdFeB under the action of the elastic member 1210, and then the electric belt conveyor group 122 can be controlled to operate to drive the guide frame 123 to move. When the guide frame 123 moves, it can drive the NdFeB to move. When the NdFeB moves Then it can contact with grinding plate 1 124 and grinding plate 2 127, so that the left and right sides of the neodymium iron boron can be polished by grinding plate 1 124 and grinding plate 2 127. In this way, the six sides of the neodymium iron boron can be polished at the same time, and there is no need to repeatedly polish different surfaces, and the polishing efficiency is higher. In the actual operation process, the screw 126 can be rotated to drive the grinding plate 2 127 to move through the thread according to the size of the neodymium iron boron to adjust the distance between the grinding plate 2 127 and the grinding plate 1 124, so that the distance between the grinding plate 2 127 and the grinding plate 1 124 is adapted to the size of the neodymium iron boron.

[0040] like Fig.10 As shown, it also includes an electric push rod 13. The electric push rod 13 is installed on both the front and rear sides of the guide frame 123. The telescopic rod of the electric push rod 13 is connected to the sliding shaft 128. The operation of the electric push rod 13 can drive the sliding shaft 128 to move, thereby adjusting the positions of the two sliding shafts 128 to adjust the distance between the clamping plates 129 on the front and rear sides, so that the distance between the clamping plates 129 matches the size of the neodymium iron boron.
