Description

Technical Field

[0001] The invention relates to the field of permanent magnet motor magnetic steel assembly, and in particular to a permanent magnet motor magnetic steel assembly process and equipment. Background Art

[0002] The application scope of high-efficiency permanent magnet motors has gradually expanded with the development of permanent magnet technology and motor control technology. The technical means of using permanent magnets instead of excitation windings for excitation has greatly improved the working efficiency of motors. In order to achieve high working efficiency, the magnetic steel used by permanent magnet motors is mostly rare earth permanent magnets. This type of magnetic steel is more difficult to assemble due to its strong magnetic force. According to different magnetic steel assembly schemes, the process of assembling magnetic steel for permanent magnet motors can be roughly divided into motor rotor core surface mounting and motor core embedded assembly. Both schemes use magnetic steel adhesive to fix the magnetic steel.

[0003] According to the public patent 201910476062.2, a permanent magnet motor magnet steel assembly process and equipment includes a base, the top of the base is welded with four support rods in an equidistant and circular shape, and the bottom ends of the four support rods are welded to the bottom of the placement frame, the motor core is placed in the placement frame, and the bottom of the motor core is provided with a magnetic steel slot, the top of the placement frame is provided with a through slot that runs through the bottom of itself, the through slot coincides with the magnetic steel slot, and a forward and reverse motor is embedded in the middle of the base. The permanent magnet motor magnet steel assembly process and equipment automatically opens the opening and closing mechanism to discharge the glue when the magnetic steel enters the gluing mechanism, and the glue is applied to the surface of the magnetic steel with the help of the bristles. The smoothing mechanism contacts and smoothes the strips of glue applied by the bristles, ensuring the rapid gluing effect on the magnetic steel, while increasing the coverage area and uniformity of the glue.

[0004] However, in the field of permanent magnet motor manufacturing, for the traditional magnetic steel assembly process and the equipment used, in terms of the magnetic steel surface gluing link, the existing practice mainly focuses on the glue coating of the four side walls of the magnetic steel. However, in the subsequent magnetic steel assembly process, the top and bottom of the magnetic steel will also come into direct contact with the magnetic steel slot. Since this part of the area is not coated with glue, the top and bottom of the magnetic steel are prone to position displacement or shaking during assembly, reducing the overall stability of the magnetic steel. In addition, based on the material properties, the glue on the surface of the magnetic steel after gluing is in a semi-cured and easy-to-flow state in the early stage. In this state, the glue is easy to slide off quickly due to factors such as gravity and surface tension, and it is difficult to form a uniform and stable coating on the surface of the magnetic steel. This uneven distribution of glue not only directly affects the gluing quality of the magnetic steel surface, but also further aggravates the positioning problem during the assembly process, and ultimately has an adverse effect on the overall performance and reliability of the permanent magnet motor. To this end, it is necessary to design a new technical solution to solve it. Summary of the invention

[0005] The purpose of the present invention is to overcome the shortcomings of the prior art, meet the actual needs, and provide a permanent magnet motor magnetic steel assembly process and equipment to solve the current permanent magnet motor manufacturing field. For the traditional magnetic steel assembly process and the equipment used therein, in terms of the magnetic steel surface gluing link, the existing practice mainly focuses on the four side walls of the magnetic steel for glue coating. However, in the subsequent magnetic steel assembly process, the top and bottom of the magnetic steel will also come into direct contact with the magnetic steel slot. Since this part of the area is not coated with glue, the top and bottom of the magnetic steel are prone to positional displacement or shaking during assembly, reducing the overall stability of the magnetic steel. In addition, based on the material properties, the glue on the surface of the magnetic steel after gluing is in a semi-cured and easy-to-flow state in the early stage. In this state, the glue is easy to slide off quickly due to factors such as gravity and surface tension, and it is difficult to form a uniform and stable coating on the surface of the magnetic steel. This uneven distribution of glue not only directly affects the gluing quality of the magnetic steel surface, but also further aggravates the positioning problem during the assembly process, and ultimately has an adverse effect on the overall performance and reliability of the permanent magnet motor.

[0006] In order to achieve the purpose of the present invention, the technical solution adopted by the present invention is: designing a permanent magnet motor magnet assembly device, including an equipment box, an L-shaped plate is fixed on one side of the top of the equipment box, an electric telescopic cylinder is installed on one side of the bottom of the L-shaped plate, a fixed plate is installed on the bottom of the electric telescopic cylinder, a groove is opened at the bottom of the electric telescopic cylinder, a first motor is installed inside the groove, a first motor shaft is connected to the bottom of the first motor, a wind wheel is fixed on the bottom of the first motor shaft through the fixed plate, and a transmission assembly is arranged on the outside of the first motor shaft for driving multiple magnets to rotate.

[0007] Preferably, the transmission assembly includes a first gear, a second gear, a rotating rod, a bearing, a circular groove, and a limit housing. The first motor shaft passes through the inside of the first gear, and the penetration position of the first motor shaft and the first gear is fixed. A plurality of second gears are meshed on the outside of the first gear.

[0008] Preferably, a rotating rod passes through the inside of the second gear, and the penetration position of the rotating rod and the second gear is fixed. A bearing is rotatably connected to the top of the rotating rod, and the bearing is installed in a plurality of circular grooves opened at the bottom of the fixed plate.

[0009] Preferably, cavities are opened on both sides of the fixing plate, and electric heating tubes are installed in the cavities.

[0010] Preferably, a limiting shell is fixed at the bottom of the rotating rod, and first fixed cylinders are installed at both ends of the limiting shell, a second fixed cylinder extends into the first fixed cylinder, a movable disk is fixed at one end of the second fixed cylinder located in the first fixed cylinder, and a spring is fixed at one end of the movable disk.

[0011] Preferably, one end of the second fixing tube away from the first fixing tube extends into the limiting shell, one end of the second fixing tube located in the limiting shell is fixed with a clamping plate, and one end of the clamping plate is installed with a vibration motor.

[0012] Preferably, a second motor is installed on one side of the top of the device case, a second motor shaft is connected to the bottom of the second motor, the bottom of the second motor shaft extends into the device case, a connecting rod is fixed to one end of the second motor shaft located in the device case, a plurality of stirring rods are fixed on both sides of the connecting rod, and electric heating wires are fixed inside the plurality of stirring rods.

[0013] Preferably, a round hole is opened on one side of the top of the equipment box, an insert tube is installed on one side of the bottom end of the equipment box, and an opening is arranged on the top of the insert tube, so that when the wind wheel moves downward, it will enter into the insert tube.

[0014] Preferably, the upper and lower ends of one side of the equipment box are connected to one end of a pipe, the other end of the pipe is detachably connected to a pipe cover, a control host is installed at the front end of the equipment box, and rotating wheels are installed at the four corners of the bottom of the equipment box.

[0015] Preferably, a permanent magnet motor magnetic steel assembly process adopts the permanent magnet motor magnetic steel assembly equipment, and the steps of the permanent magnet motor magnetic steel assembly process are as follows:

[0016] S1. First, insert multiple magnets into multiple limit shells, and use the limit shells to limit the magnets. When the magnets are inserted into the limit shells, the elastic force of the spring will drive the second fixed cylinder and the clamping plate to move, and the movable clamping plate will be used to clamp magnets of different sizes. At the same time, a vibration motor is arranged on the surface of the clamping plate. After the vibration motor is turned on, the vibration energy can be accurately transmitted to the surface of the magnet. While the magnet rotates, it acts as a medium for vibration transmission, further diffusing the vibration effect to the surrounding glue, thereby achieving uniform vibration stirring of the glue. This process effectively solves the uniformity problem caused by uneven standing or stirring of the glue in the traditional glue coating method, thereby avoiding the adverse effects on the glue coating quality caused by uneven distribution of the glue. In addition, after the glue coating operation on the magnet surface is completed, the vibration motor can continue to play a role, and by slightly vibrating the surface of the magnet, the surface glue is further evenly distributed and tiny bubbles or defects are eliminated;

[0017] S2. After the magnetic steel is limited, when it is necessary to apply glue to the surface of the magnetic steel, the electric telescopic cylinder is turned on, and the electric telescopic cylinder will drive the fixed plate to move downward, and the fixed plate will drive multiple limit shells and magnetic steel to move downward. During the downward movement of the fixed plate, the wind wheel will enter the insertion tube, and the magnetic steel will pass through the round hole into the glue in the equipment box, so as to directly apply glue to different positions on the surfaces of multiple magnetic steels in an all-round manner;

[0018] S3. During the gluing process, the first motor is turned on, the first motor drives the first motor shaft, the first motor shaft drives the first gear, the first gear drives the plurality of second gears to rotate, the second gear drives the rotating rod to rotate through the bearing, the rotating rod drives the limit housing and the magnetic steel to rotate, and the plurality of magnetic steels are driven to rotate at the same time, so that the plurality of magnetic steels rotate to stir the surrounding glue, and the glue is uniformly made, and the surface of the magnetic steel is uniformly contacted with the glue, thereby improving the uniformity of the glue on the surface of the magnetic steel;

[0019] S4. After the magnet moves up and separates from the glue, the first motor shaft will also drive the wind wheel to rotate, and by driving the wind wheel and multiple magnets to rotate at the same time, the wind wheel can generate wind to blow the surfaces of the rotating multiple magnets, so that the glue on the surface of the magnet becomes viscous when it is cooled, and when it is inserted into the magnet slot, the glue on the surface of the magnet is prevented from sliding down quickly;

[0020] S5. When it is necessary to prevent the glue liquid in the equipment box from solidifying, turn on the second motor, the second motor drives the second motor shaft, the second motor shaft drives the connecting rod to rotate, and the connecting rod drives multiple stirring rods to stir the glue liquid, effectively preventing the glue liquid from solidifying or stratifying due to standing for too long, ensuring that the glue liquid maintains its fluidity and uniformity;

[0021] S6. When the stirring rod rotates and stirs the glue liquid under the drive of the motor, the heating wire works synchronously, and the thermal effect of the current generates an appropriate amount of heat on the surface of the stirring rod. This heat directly acts on the contact interface between the stirring rod and the glue liquid, effectively promoting the melting and reflow of the viscous or initially solidified glue liquid.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The present invention combines a wind wheel, a transmission component and a limit housing, and can limit the position of multiple magnetic steels through multiple limit housings, and directly extend multiple magnetic steels into the glue in the equipment box by using an electric telescopic cylinder, so as to directly apply glue to different positions on the surfaces of multiple magnetic steels in an all-round manner. In addition, during the gluing process, the transmission component can simultaneously drive multiple magnetic steels to rotate, so that the rotation of multiple magnetic steels stirs the surrounding glue, and while homogenizing the glue, the surface of the magnetic steel is also uniformly contacted with the glue, thereby improving the glue on the surface of the magnetic steel. The uniformity of water, not only that, after the magnetic steel moves up and leaves the glue liquid, it can drive the wind wheel and multiple magnetic steels to rotate at the same time through the transmission assembly, and the wind wheel can generate wind to blow the rotating multiple magnetic steel surfaces, so that the glue on the surface of the magnetic steel becomes viscous when it is cold, and when it is inserted into the magnetic steel slot, the glue on the surface of the magnetic steel is prevented from sliding down quickly, which solves the current permanent magnet motor manufacturing field. For the traditional magnetic steel assembly process and the equipment used, as far as the magnetic steel surface glue coating link is concerned, the existing practice mainly focuses on the four side walls of the magnetic steel for glue coating. However, in the subsequent magnetic steel assembly process, the top and bottom of the magnetic steel will also come into direct contact with the magnetic steel slot. Since this part of the area is not coated with glue, the top and bottom of the magnetic steel are prone to position displacement or shaking during assembly, which reduces the overall stability of the magnetic steel. In addition, based on the material properties, the glue on the surface of the magnetic steel after glue coating is in a semi-cured and easy-to-flow state in the early stage. In this state, the glue is easy to slide quickly due to factors such as gravity and surface tension, and it is difficult to form a uniform and stable coating on the surface of the magnetic steel. This uneven distribution of glue not only directly affects the bonding quality of the magnetic steel surface, but also further aggravates the positioning problem during the assembly process, ultimately creating a technical problem that adversely affects the overall performance and reliability of the permanent magnet motor.

[0024] 2. The present invention, through the combination of a limit shell, a fixed cylinder and a vibration motor, can not only use multiple limit shells to limit and clamp magnets of different sizes, but also, when the magnet is immersed in the glue and starts the rotation action, the vibration motor, as the core power source, can accurately transfer the vibration energy to the surface of the magnet. While the magnet is rotating, as a medium for vibration transmission, it further diffuses the vibration effect into the surrounding glue, thereby achieving uniform vibration stirring of the glue. This process effectively solves the uniformity problem caused by uneven standing or stirring of the glue in the traditional glue coating method, thereby avoiding the adverse effects on the glue coating quality caused by uneven distribution of the glue. In addition, after the glue coating operation on the surface of the magnet is completed, the vibration motor can continue to play a role, and by slightly vibrating the surface of the magnet, the surface glue is further evenly distributed and tiny bubbles or defects are eliminated, thereby achieving the purpose of improving the overall uniformity and density of the glue coating layer. The optimization of this link is of great significance for improving the bonding strength between the magnet and the glue layer and the overall assembly quality.

[0025] 3. The present invention combines a second motor, a stirring rod and a heating wire. The stirring rod continuously rotates and stirs in the glue liquid container, which effectively prevents the glue liquid from solidifying or stratifying due to standing for too long, ensures that the glue liquid maintains its fluidity and uniformity, and provides a stable material basis for subsequent gluing operations. Furthermore, in order to cope with the viscosity increase or initial solidification trend of the glue liquid under specific conditions, a heating wire assembly is integrated inside the stirring rod. When the stirring rod rotates and stirs the glue liquid under the drive of the motor, the heating wire works synchronously, and the thermal effect of the current generates an appropriate amount of heat on the surface of the stirring rod. This heat directly acts on the contact interface between the stirring rod and the glue liquid, effectively promoting the melting and reflow of the viscous or initially solidified glue liquid, thereby further improving the uniformity and processability of the glue liquid.

The plurality of magnetic steels are firstly rotated Insert into the interior of multiple limit shells 3, use the limit shells 3 to limit the magnetic steel, after the magnetic steel is limited, when it is necessary to apply glue to the surface of the magnetic steel, open the electric telescopic cylinder 201, the electric telescopic cylinder 201 will drive the fixed plate 202 to move downward, the fixed plate 202 will drive multiple limit shells 3 and the magnetic steel to move downward, and in the process of the fixed plate 202 moving downward, the wind wheel 206 will enter the insertion tube 102, and the magnetic steel will pass through the circular hole 101 and enter the glue in the equipment box 1, so as to directly apply glue to different positions on the surface of multiple magnetic steels in an all-round manner, and in the process of applying glue During the process, the first motor 204 can be turned on, the first motor 204 drives the first motor shaft 205, the first motor shaft 205 drives the first gear 207, the first gear 207 drives the plurality of second gears 210 to rotate, the second gear 210 drives the rotating rod 211 to rotate through the bearing 209, the rotating rod 211 drives the limit housing 3 and the magnetic steel to rotate, and drives the plurality of magnetic steels to rotate at the same time, so that the plurality of magnetic steels rotate to stir the surrounding glue, and while the glue is homogenized, the surface of the magnetic steel is evenly contacted with the glue, thereby improving the uniformity of the glue on the surface of the magnetic steel. Moreover, after the magnet moves up and leaves the glue, the first motor shaft 205 will also drive the wind wheel 206 to rotate, and by driving the wind wheel 206 and multiple magnets to rotate at the same time, the wind wheel 206 can generate wind to blow the rotating multiple magnet surfaces, so that the glue on the magnet surface becomes viscous when it is cold, and when it is inserted into the magnet groove, the glue on the magnet surface is prevented from sliding down quickly, which solves the current permanent magnet motor manufacturing field. For the traditional magnet assembly process and the equipment used therein, as far as the magnet surface glue coating link is concerned, the existing practice mainly focuses on the four side walls of the magnet for glue coating. However, in the subsequent magnet assembly process, the top and bottom of the magnet will also come into direct contact with the magnet groove. Since this part of the area is not coated with glue, the top and bottom of the magnet are prone to positional displacement or shaking during assembly, which reduces the overall stability of the magnet. In addition, based on the material properties, the glue on the magnet surface after glue coating is in a semi-cured and easy-to-flow state in the early stage. In this state, the glue tends to slide off quickly due to factors such as gravity and surface tension, making it difficult to form a uniform and stable coating on the surface of the magnetic steel. This uneven distribution of glue not only directly affects the gluing quality of the magnetic steel surface, but also further exacerbates the positioning problem during the assembly process, ultimately causing technical problems that adversely affect the overall performance and reliability of the permanent magnet motor.

[0033] For details, see Figure 2 The transmission assembly includes a first gear 207, a second gear 210, a rotating rod 211, a bearing 209, a circular groove 208, and a limit housing 3. The first motor shaft 205 passes through the first gear 207, and the penetration position of the first motor shaft 205 and the first gear 207 is fixed. A plurality of second gears 210 are meshed in a circle outside the first gear 207.

[0034] For more details, see Figure 2 A rotating rod 211 passes through the inside of the second gear 210, and the penetration position of the rotating rod 211 and the second gear 210 is fixed. A bearing 209 is rotatably connected to the top of the rotating rod 211, and the bearing 209 is installed in a plurality of circular grooves 208 opened at the bottom of the fixed plate 202.

[0035] For further information, see Figure 2 Cavities 212 are provided on both sides of the interior of the fixed plate 202 , and electric heating tubes 213 are installed inside the cavities 212 .

[0036] Further, see Figure 3 A limiting shell 3 is fixed at the bottom of the rotating rod 211, and a first fixed cylinder 305 is installed at both ends of the limiting shell 3, and a second fixed cylinder 306 is inserted into the first fixed cylinder 305. A movable disk 302 is fixed at one end of the second fixed cylinder 306 located in the first fixed cylinder 305, and a spring 301 is fixed at one end of the movable disk 302. When the magnetic steel is inserted into the limiting shell 3, the elastic force of the spring 301 will drive the second fixed cylinder 306 and the clamping plate 303 to move, and the moving clamping plate 303 will clamp magnetic steels of different sizes. At the same time, a vibration motor 304 is arranged on the surface of the clamping plate 303. After turning on the vibration motor 304, the vibration energy can be accurately transmitted to the surface of the magnetic steel. While the magnetic steel rotates, it acts as a medium for vibration transmission, further diffusing the vibration effect into the surrounding glue, thereby realizing uniform vibration stirring of the glue. This process effectively solves the uniformity problem caused by uneven standing or stirring of the glue in the traditional glue coating method, thereby avoiding the adverse effects on the glue coating quality caused by uneven distribution of the glue. In addition, after the glue coating operation on the magnetic steel surface is completed, the vibration motor 304 can continue to play a role, by slightly vibrating the magnetic steel surface, so as to further evenly distribute the surface glue and eliminate tiny bubbles or defects, thereby achieving the purpose of improving the overall uniformity and density of the glue coating layer. The optimization of this link is of great significance for improving the bonding strength between the magnetic steel and the glue layer and the overall assembly quality.

[0037] It is worth noting that see Figure 3One end of the second fixed cylinder 306 away from the first fixed cylinder 305 extends into the limiting shell 3, and one end of the second fixed cylinder 306 located in the limiting shell 3 is fixed with a clamping plate 303, and one end of the clamping plate 303 is installed with a vibration motor 304.

[0038] It is worth noting that see Figure 4 A second motor 4 is installed on one side of the top of the device box 1, and a second motor shaft 401 is connected to the bottom of the second motor 4. The bottom of the second motor shaft 401 extends into the device box 1. A connecting rod 402 is fixed to one end of the second motor shaft 401 located in the device box 1. A plurality of stirring rods 403 are fixed on both sides of the connecting rod 402. Electric heating wires are fixed inside the plurality of stirring rods 403. When it is necessary to prevent the glue in the device box 1 from solidifying, the second motor 4 can be turned on, and the second motor 4 drives the second motor shaft 401, and the second motor shaft 401 drives the connecting rod 402 to rotate When the connecting rod 402 rotates, the connecting rod 402 will drive the multiple stirring rods 403 to stir the glue liquid, which effectively prevents the glue liquid from solidifying or stratifying due to standing for too long, and ensures that the glue liquid maintains its fluidity and uniformity. When the stirring rod 403 rotates and stirs the glue liquid under the drive of the motor, the heating wire works synchronously, and generates an appropriate amount of heat on the surface of the stirring rod 403 through the thermal effect of the current. The heat directly acts on the contact interface between the stirring rod 403 and the glue liquid, effectively promoting the melting and reflow of the viscous or initially solidified glue liquid, thereby further improving the uniformity and workability of the glue liquid.

[0039] It is worth mentioning that see Figure 1 A round hole 101 is provided on one side of the top of the equipment box 1, and an insert 102 is installed on one side of the bottom end of the equipment box 1. An opening is provided on the top of the insert 102, and when the wind wheel 206 moves downward, it will enter the insert 102.

[0040] It is worth emphasizing that see Figure 1 One end of a pipe 105 is connected to both upper and lower ends of one side of the equipment box 1, and the other end of the pipe 105 is detachably connected to a pipe cover 106. A control host 103 is installed at the front end of the equipment box 1, and wheels 104 are installed at the four corners of the bottom of the equipment box 1.

[0041] A permanent magnet motor magnetic steel assembly process, using permanent magnet motor magnetic steel assembly equipment, the permanent magnet motor magnetic steel assembly process steps are as follows:

[0042] S1. First, multiple magnets are inserted into multiple limiting shells 3, and the limiting shells 3 are used to limit the magnets. When the magnets are inserted into the limiting shells 3, the elastic force of the spring 301 will drive the second fixed cylinder 306 and the clamping plate 303 to move, and the moving clamping plate 303 will clamp magnets of different sizes. At the same time, a vibration motor 304 is arranged on the surface of the clamping plate 303. After the vibration motor 304 is turned on, the vibration energy can be accurately transmitted to the surface of the magnet. While the magnet rotates, it acts as a medium for vibration transmission, further diffusing the vibration effect to the surrounding glue, thereby achieving uniform vibration stirring of the glue. This process effectively solves the uniformity problem caused by the static or uneven stirring of the glue in the traditional glue coating method, thereby avoiding the adverse effects on the glue coating quality caused by the uneven distribution of the glue. In addition, after the glue coating operation on the surface of the magnet is completed, the vibration motor 304 can still continue to play a role, and by slightly vibrating the surface of the magnet, the surface glue is further evenly distributed and tiny bubbles or defects are eliminated;

[0043] S2. After the magnetic steel is limited, when it is necessary to apply glue to the surface of the magnetic steel, the electric telescopic cylinder 201 is turned on, and the electric telescopic cylinder 201 will drive the fixed plate 202 to move downward, and the fixed plate 202 will drive the multiple limit shells 3 and the magnetic steel to move downward. During the downward movement of the fixed plate 202, the wind wheel 206 will enter the insert tube 102, and the magnetic steel will pass through the circular hole 101 and enter the glue in the equipment box 1, so as to directly apply glue to different positions on the surfaces of multiple magnetic steels in an all-round manner;

[0044] S3. During the gluing process, the first motor 204 is turned on, the first motor 204 drives the first motor shaft 205, the first motor shaft 205 drives the first gear 207, the first gear 207 drives the plurality of second gears 210 to rotate, the second gear 210 drives the rotating rod 211 to rotate through the bearing 209, the rotating rod 211 drives the limit housing 3 and the magnetic steel to rotate, and drives the plurality of magnetic steels to rotate at the same time, so that the plurality of magnetic steels rotate to stir the surrounding glue, and while the glue is homogenized, the surface of the magnetic steel is evenly contacted with the glue, thereby improving the uniformity of the glue on the surface of the magnetic steel;

[0045] S4. After the magnet moves upward and separates from the glue, the first motor shaft 205 also drives the wind wheel 206 to rotate. By driving the wind wheel 206 and the multiple magnets to rotate at the same time, the wind wheel 206 can generate wind to blow the surfaces of the multiple rotating magnets, so that the glue on the surface of the magnet becomes viscous when it is cooled, and when it is inserted into the magnet slot, the glue on the surface of the magnet is prevented from sliding down quickly;

[0046] S5. When it is necessary to prevent the glue liquid in the equipment box 1 from solidifying, the second motor 4 is turned on, the second motor 4 drives the second motor shaft 401, and the second motor shaft 401 drives the connecting rod 402 to rotate, and the connecting rod 402 drives multiple stirring rods 403 to stir the glue liquid, which effectively prevents the glue liquid from solidifying or stratifying due to standing for too long, ensuring that the glue liquid maintains its fluidity and uniformity;

[0047] S6. When the stirring rod 403 rotates and stirs the glue liquid under the drive of the motor, the heating wire works synchronously, and a proper amount of heat is generated on the surface of the stirring rod 403 through the thermal effect of the current. This heat directly acts on the contact interface between the stirring rod 403 and the glue liquid, effectively promoting the melting and reflow of the viscous or initially solidified glue liquid.

10. A permanent magnet motor magnetic steel assembly process, using the permanent magnet motor magnetic steel assembly equipment as claimed in claims 1-9, the permanent magnet motor magnetic steel assembly process steps are as follows: S1. First, a plurality of magnets are inserted into a plurality of limit shells (3), and the limit shells (3) are used to limit the magnets. When the magnets are inserted into the limit shells (3), the elastic force of the spring (301) drives the second fixed cylinder (306) and the clamping plate (303) to move, and the movable clamping plate (303) is used to clamp magnets of different sizes. At the same time, a vibration motor (304) is provided on the surface of the clamping plate (303). After the vibration motor (304) is turned on, the vibration energy can be accurately transmitted to the surface of the magnet. When the magnetic steel rotates, it acts as a medium for vibration transmission, further diffusing the vibration effect to the surrounding glue liquid, thereby achieving uniform vibration stirring of the glue liquid. This process effectively solves the uniformity problem caused by the static or uneven stirring of the glue liquid in the traditional glue coating method, thereby avoiding the adverse effect on the glue coating quality caused by the uneven distribution of the glue liquid. In addition, after the glue coating operation on the magnetic steel surface is completed, the vibration motor (304) can still continue to play a role, by slightly vibrating the magnetic steel surface, so as to promote the surface glue liquid to be further evenly distributed and eliminate tiny bubbles or defects; S2. After the magnetic steel is limited, when it is necessary to apply glue to the surface of the magnetic steel, the electric telescopic cylinder (201) is turned on, and the electric telescopic cylinder (201) drives the fixed plate (202) to move downward, and the fixed plate (202) drives the plurality of limit housings (3) and the magnetic steel to move downward. During the downward movement of the fixed plate (202), the wind wheel (206) enters the insert cylinder (102), and the magnetic steel passes through the circular hole (101) and enters the glue in the equipment box (1), thereby directly applying glue to different positions on the surfaces of the plurality of magnetic steels in an all-round manner; S3. During the process of applying glue, the first motor (204) is turned on, the first motor (204) drives the first motor shaft (205), the first motor shaft (205) drives the first gear (207), the first gear (207) drives the plurality of second gears (210) to rotate, the second gears (210) drive the rotating rod (211) to rotate through the bearing (209), the rotating rod (211) drives the limit housing (3) and the magnetic steel to rotate, and the plurality of magnetic steels are driven to rotate at the same time, so that the plurality of magnetic steels rotate to stir the surrounding glue, and while the glue is homogenized, the surface of the magnetic steel is also uniformly contacted with the glue, thereby improving the uniformity of the glue on the surface of the magnetic steel; S4. After the magnetic steel moves upward and separates from the glue, the first motor shaft (205) also drives the wind wheel (206) to rotate, and drives the wind wheel (206) and the plurality of magnetic steels to rotate at the same time. The wind wheel (206) can generate wind force to blow the surfaces of the rotating plurality of magnetic steels, so that the glue on the surface of the magnetic steel becomes viscous when it is cooled, and when the magnetic steel is inserted into the magnetic steel slot, the glue on the surface of the magnetic steel is prevented from sliding down quickly; S5. When it is necessary to prevent the glue liquid in the equipment box (1) from solidifying, the second motor (4) is turned on, the second motor (4) drives the second motor shaft (401), the second motor shaft (401) drives the connecting rod (402) to rotate, and the connecting rod (402) drives a plurality of stirring rods (403) to stir the glue liquid, thereby effectively preventing the glue liquid from solidifying or stratifying due to being left standing for too long, and ensuring that the glue liquid maintains its fluidity and uniformity; S6. When the stirring rod (403) rotates and stirs the glue liquid under the drive of the motor, the heating wire works synchronously, and a proper amount of heat is generated on the surface of the stirring rod (403) through the thermal effect of the current. This heat directly acts on the contact interface between the stirring rod (403) and the glue liquid, effectively promoting the melting and reflow of the viscous or initially solidified glue liquid.
