The neodymium-iron-boron magnet generally undergoes processes such as smelting, powder making, pressing forming, sintering, grinding processing, cutting processing and electroplating during production and processing. After the neodymium-iron-boron magnet is processed by a grinding machine, debris is generated on the surface of the magnet and the magnet is contaminated with cooling liquid. After the processed neodymium-iron-boron magnet is cleaned, liquid is attached to the surface of the neodymium-iron-boron magnet. When the neodymium-iron-boron magnet is further processed, the neodymium-iron-boron magnet needs to be dried.

[0023] Compared with the prior art, the neodymium-iron-boron permanent magnet processing drying equipment and method has the advantages that the multiple drying conveying frames, vertical overturning supports and horizontal overturning supports can realize multi-surface overturning of the magnet, improve the drying path of the magnet, adapt to the magnet processing assembly line with a large number of magnets, change the inclination angle of the drying conveying frame, facilitate the improvement of the moving speed of the magnet, accelerate the conveying efficiency of the magnet, avoid the magnet from being stuck in the gap between the two drying rollers, and thus affect the drying rate of the magnet, and through the height adjustment of the conveying support, different drying paths can be selected according to the size and surface area of the magnet, so that the energy is saved and the drying efficiency is improved. 1. By setting up a multi-faceted rotating drying mechanism, the rotation of the first and second sealing baffles and sealing plates can be achieved using the elastic force of the first and second torsion spring hinges, thus sealing the drying chamber and preventing heat loss. By starting the first conveyor motor, the conveyor sprockets and drying rollers rotate. Utilizing the meshing connection between the conveyor sprockets and the first conveyor chain, multiple conveyor sprockets and drying rollers can rotate. The drying instrument generates hot air, which enters the drying rollers through connecting hoses and drying diverter pipes. This achieves both the conveying of the magnets and the drying of the magnets during their movement. Simultaneously, the conveyor chain... The wheel drives the transmission sprocket assembly and the vertical flipping shaft to rotate, which in turn drives the vertical flipping plate to rotate, enabling the magnet to flip vertically. Simultaneously, the horizontal flipping motor starts, driving the horizontal flipping shaft and horizontal flipping baffles to rotate. Since there are three horizontal flipping baffles set at 120 degrees, the magnet can rotate horizontally, facilitating adjustment of its horizontal position and enabling multi-sided flipping. This allows for uniform drying of multiple sides of the magnet, improving both drying uniformity and drying effect. By setting multiple sets of drying conveyor racks, vertical flipping supports, and horizontal flipping supports, multi-sided flipping of the magnet can be achieved, and the drying path of the magnet can be improved. This design is suitable for processing large numbers of magnets on a production line. By starting a bidirectional winding motor, the winding connecting shaft and winding roller rotate, allowing the winding rope wound on the roller to extend or retract. Since the end of the winding rope is fixedly connected to the top vertical tilting bracket, and connecting ropes are fixedly connected between the drying conveyor frames, the extension or retraction of the winding rope allows the drying conveyor frames to tilt. Changing the tilt angle of the drying conveyor frames increases the movement speed of the magnets, accelerating the conveying efficiency and preventing the magnets from getting stuck in the gap between the two drying rollers, thus affecting the drying rate. During the extension or retraction of the winding rope, the bidirectional motor is activated... A bidirectional motor drives a reciprocating threaded rod to rotate, causing the reciprocating threaded sleeve to move back and forth on the outside of the reciprocating threaded rod while simultaneously driving the reciprocating limiting sleeve to move back and forth. Under the limiting action of the reciprocating limiting sleeve, the winding rope can be wound evenly, avoiding the phenomenon of winding rope tangling and knotting, which would affect the angle adjustment of the drying conveyor. Compared with setting up a robot arm and ordinary flipping structure, it is not convenient to flip a large number of magnets and is not suitable for large-scale assembly line production. This solution can realize multi-face automatic flipping of magnets, which is suitable for large-scale magnet drying production lines. It will not cause the inability to flip due to the position deviation of the magnets, thus saving drying costs and improving the drying efficiency of magnets. 2. By setting the lifting conveying mechanism, the movement of the conveying support can be realized by the universal wheel at the bottom of the supporting base, the first chain wheel transmission assembly and the conveying roller are driven to rotate by starting the second conveying motor, the transmission connection between the conveying roller and the conveying belt is utilized, and the conveying of the magnet is realized under the action of the supporting roller, the first sealing baffle on one side of the conveying support can be pushed open by the ejection rod, so that the magnet can be conveyed to the drying conveying frame for uniform drying, the second chain wheel transmission assembly and the lifting bidirectional threaded rod are driven to rotate by starting the lifting motor, the lifting threaded sleeve moves on the outside of the lifting bidirectional threaded rod at the same time, the top rotating support moves, the lifting rotating rod rotates around the rotating connection shaft under the action of the top rotating support, and the lifting sliding sleeve moves on the outside of the lifting sliding rod under the action of the bottom rotating support, the distance between the lifting chassis and the lifting top frame can be adjusted under the action of the connecting spring, so that the height adjustment of the conveying support can be realized, different drying paths can be selected according to the size and surface area of the magnet, for the magnet with large volume and large surface area, the magnet can be conveyed to the first sealing baffle at the top for long-path drying, for the magnet with small volume and small surface area, the magnet can be conveyed to the first sealing baffle at the middle for short-path drying, so that the effect of saving energy and accelerating drying efficiency is achieved.

[0032] Working principle: before using the neodymium iron boron permanent magnet processing drying equipment and method, the overall situation of the device needs to be checked to determine whether it can work normally, according to Figure 1 Figure 11 ​As shown, first, the universal wheel 202 at the bottom of the support base 201 is used to realize the movement of the conveying bracket 205, while the second conveying motor 208 is started to drive the first sprocket transmission assembly 209 and the conveying roller 210 to rotate, the conveying roller 210 and the conveying belt 211 are transmissionally connected, and the support roller 212 is used to realize the conveying of the magnet, the ejection rod 206 on one side of the conveying bracket 205 can top off the first sealing baffle 103, which is convenient for conveying the magnet to the drying conveying frame 108 for uniform drying, the lifting motor 216 is started to drive the second sprocket transmission assembly 217 and the lifting bidirectional threaded rod 218 to rotate, the lifting threaded sleeve 219 moves relatively outside the lifting bidirectional threaded rod 218 to drive the top rotating support 220 to move, the top rotating support 220 drives the lifting rotating rod 221 to rotate around the rotating connecting shaft 222, the bottom rotating support 223 drives the lifting sliding sleeve 224 to move relatively outside the lifting sliding rod 225, under the action of the connecting spring 226, the distance between the lifting undercarriage 215 and the lifting top bracket 213 can be adjusted, so that the height of the conveying bracket 205 can be adjusted, different drying paths can be selected according to the size and surface area of the magnet, for the magnet with large volume and large surface area, the magnet can be conveyed to the first sealing baffle 103 at the top for long-path drying, for the magnet with small volume and small surface area, the magnet can be conveyed to the first sealing baffle 103 at the middle for short-path drying, so that the energy can be saved and the drying efficiency can be improved.

[0033] Secondly, the elastic force of the first torsional spring hinge 104 and the second torsional spring hinge 106 is utilized to rotate the first sealing baffle 103 and the second sealing baffle 105, so that the drying box 101 can be closed, and the heat loss can be avoided. The first conveying motor 112 is started to drive the conveying sprocket 111 and the drying roller 113 to rotate. The conveying sprocket 111 and the first conveying chain 110 are meshed and connected, so that the conveying sprocket 111 and the drying roller 113 can rotate. The drying instrument 116 generates drying hot air, which enters the inside of the drying roller 113 through the connecting hose 115 and the drying shunt pipe 114, so that the magnets can be conveyed and dried at the same time. The conveying sprocket 111 drives the transmission sprocket assembly 119 and the vertical overturning shaft 120 to rotate, so that the vertical overturning shaft 120 drives the vertical overturning plate 121 to rotate, and the magnets can be turned over in the vertical direction. The horizontal overturning motor 124 is started to drive the horizontal overturning shaft 125 and the horizontal overturning baffle 126 to rotate. Since the number of the horizontal overturning baffles 126 is three, and they are arranged at 120 degrees, the unfolding angle of two adjacent horizontal overturning baffles 126 is the same as the width of the drying conveying frame 108, so that the magnets can enter between two adjacent horizontal overturning baffles 126, and the horizontal rotation of the magnets can be realized, which is convenient for adjusting the horizontal position of the magnets, so that the multi-surface overturning of the magnets can be realized, and the magnets can be evenly dried on multiple surfaces, which improves the drying uniformity and the drying effect of the magnets. The multiple drying conveying frames 108, the vertical overturning bracket 117 and the horizontal overturning bracket 123 are arranged, so that the multi-surface overturning of the magnets can be realized, and the drying path of the magnets can be improved, so that the magnet processing assembly line with a large number of magnets can be adapted.

[0034] Finally, the winding connection shaft 130 and the winding roller 133 are driven to rotate by starting the winding bidirectional motor 129, so that the winding rope 134 wound on the winding roller 133 can be elongated or contracted. Since the end of the winding rope 134 is fixedly connected with the top vertical turnover support 117, and the connecting rope 122 is fixedly connected between the drying conveying frames 108, the drying conveying frames 108 can be inclined under the action of the elongation or contraction of the winding rope 134. By changing the inclination angle of the drying conveying frames 108, the moving speed of the magnets can be improved, the conveying efficiency of the magnets can be improved, and the magnets can be prevented from being stuck in the gap between the two drying rollers 113, so as to affect the drying rate of the magnets. When the winding rope 134 is elongated or contracted, the reciprocating screw rod 138 is driven to rotate by starting the reciprocating bidirectional motor 137, so that the reciprocating screw sleeve 139 moves reciprocally on the outside of the reciprocating screw rod 138, and the reciprocating limiting sleeve 140 moves reciprocally. Under the limiting action of the reciprocating limiting sleeve 140, the winding rope 134 can be uniformly wound, so that the winding rope 134 is prevented from being wound and knotted, and the angle adjustment of the drying conveying frame 108 is affected.

10. A method for drying equipment used in processing neodymium iron boron permanent magnets, comprising using the drying equipment for processing neodymium iron boron permanent magnets as described in claim 9, characterized in that... The steps are as follows: Step 1: The conveyor bracket (205) is moved using the casters (202) at the bottom of the support base (201). At the same time, the second conveyor motor (208) is started to drive the first sprocket transmission assembly (209) and the conveyor roller (210) to rotate. The magnet is conveyed by utilizing the transmission connection between the conveyor roller (210) and the conveyor belt (211) and under the action of the support roller (212). The first sealing baffle (103) can be opened by the push rod (206) on one side of the conveyor bracket (205) to facilitate the conveying of the magnet to the drying conveyor rack (108) for uniform drying. The lifting motor (216) is started to drive the second sprocket transmission assembly (217) and the lifting double-threaded rod (218) to rotate, so that the lifting threaded sleeve (219) moves relative to the outside of the lifting double-threaded rod (218) while driving the top to rotate. The moving support (220) moves, and at the same time the top rotating support (220) drives the lifting rotating rod (221) to rotate around the rotating connecting shaft (222). At the same time, the bottom rotating support (223) drives the lifting sliding sleeve (224) to move relative to the outside of the lifting sliding rod (225). Under the action of the connecting spring (226), the distance between the lifting base frame (215) and the lifting top frame (213) can be adjusted, thereby realizing the height adjustment of the conveying bracket (205). Different drying paths can be selected according to the size and surface area of ​​the magnet. For magnets with larger volume and larger surface area, the magnet can be conveyed to the first sealing baffle (103) at the top for long-path drying. For magnets with smaller volume and smaller surface area, the magnet can be conveyed to the first sealing baffle (103) in the middle for short-path drying. Step 2: Utilizing the elastic force of the first torsion spring hinge (104) and the second torsion spring hinge (106), the first sealing baffle (103) and the second sealing plate (105) are rotated, thereby achieving the closure of the drying chamber (101). By starting the first conveyor motor (112), the conveyor sprocket (111) and the drying roller (113) are driven to rotate. Utilizing the meshing connection between the conveyor sprocket (111) and the first conveyor chain (110), multiple conveyor sprockets (111) and the drying roller (113) can be rotated, generating drying heat through the drying instrument (116). Hot dry air enters the interior of the drying roller (113) through the connecting hose (115) and the drying diversion pipe (114), which can both transport the magnet and dry it during the movement and transport of the magnet. At the same time, the conveying sprocket (111) drives the transmission sprocket assembly (119) and the vertical flipping shaft (120) to rotate, so that the vertical flipping shaft (120) drives the vertical flipping plate (121) to rotate, which can realize the vertical flipping of the magnet. At the same time, the horizontal flipping motor (124) is started to drive the horizontal flipping shaft (125) and the horizontal flipping baffle (126) to rotate. Step 3: By starting the bidirectional winding motor (129), the winding connecting shaft (130) and the winding roller (133) are driven to rotate, so that the winding rope (134) wound on the winding roller (133) can extend or retract. Since the end of the winding rope (134) is fixedly connected to the vertical flipping bracket (117) at the top, and the connecting rope (122) is fixedly connected between the drying conveyor frames (108), the winding rope (134) can extend or retract during operation. Using this method, the drying conveyor frame (108) can be tilted. When the winding rope (134) is extended or retracted, the reciprocating bidirectional motor (137) is started to drive the reciprocating threaded rod (138) to rotate. This causes the reciprocating threaded sleeve (139) to move back and forth on the outside of the reciprocating threaded rod (138) while driving the reciprocating limiting sleeve (140) to move back and forth. Under the limiting action of the reciprocating limiting sleeve (140), the winding rope (134) can be wound evenly.
