Description

Technical Field

[0001] This invention belongs to the field of motor assembly technology, specifically relating to an intelligent assembly center for the rotor of a permanent magnet synchronous direct drive motor. Background Technology

[0002] A permanent magnet synchronous motor (PMSM) is a synchronous motor that uses permanent magnets to generate a magnetic field. The rotor speed is synchronized with the current frequency of the stator windings. A PMSM consists of a stator, rotor, and end covers. The stator is essentially the same as a conventional induction motor, employing a laminated structure to reduce iron losses during operation. The rotor can be solid or made of laminated laminations. The armature windings can be concentrated full-pitch windings, distributed short-pitch windings, or unconventional windings. The working principle of a PMSM is based on the interaction between the rotating magnetic field generated by the stator and the magnetic field generated by the permanent magnets on the rotor. The rotor is equipped with pre-magnetized permanent magnets, which generate a strong magnetic field when rotating, thus providing greater output torque. The motor's control system precisely adjusts the current to ensure that the rotor rotates synchronously with the rotating magnetic field, maintaining a stable operating state.

[0003] An existing patent publication number CN 115118071 A discloses an adjustable permanent magnet direct drive motor, including a motor housing. A motor base is fixedly installed on the bottom of the motor housing. The motor base is rotatably mounted on a support platform. Support plates are fixedly installed on opposite sides of the support platform. A self-locking adjustment component is provided at the bottom of the motor base and is located on the support plates. Mounting plates are fixedly installed on the bottom of both support plates. The mounting plates are provided with mounting screw holes. The mounting plates are fixedly installed by mounting bolts installed through the internal threads of the mounting screw holes. The motor housing is provided with a heat dissipation mechanism. The motor requires manual installation, has a low level of automation, and needs some improvements.

[0004] Therefore, it is very necessary to design a highly practical intelligent assembly center for the rotor of a permanent magnet synchronous direct drive motor. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent rotor assembly center for a permanent magnet synchronous direct drive motor, in order to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a rotor intelligent assembly center for a permanent magnet synchronous direct drive motor, comprising an assembly table, the assembly table being placed on the floor of a production workshop, an mounting platform being provided on one side of the assembly table, a first movable slide rail being fixedly installed at one end of the assembly table, a second movable slide rail being fixedly installed at the other end of the assembly table, a collection trough being provided on one side of the assembly table, a discharge pipe being fixedly installed on one side of the collection trough, a camera being detachably installed on the other side of the assembly table, and assembly components and assembly ventilation components being provided on the assembly table;

[0007] The assembly assembly includes an assembly robot, an assembly placement plate, a first electric slider, a first electric telescopic rod, a second electric slider, and a second electric telescopic rod. The assembly robot is mounted on a mounting platform. The first electric slider is slidably mounted on a first moving slide rail. Two sets of the first electric telescopic rods are symmetrically mounted on one side of the first electric slider. The second electric slider is slidably mounted on a second moving slide rail. Two sets of the second electric telescopic rods are symmetrically mounted on one side of the second electric slider. The assembly placement plate is detachably mounted on one end of the four sets of electric telescopic rods. A permanent magnet synchronous direct drive motor is placed on the assembly placement plate.

[0008] The present invention further describes that the assembly ventilation component includes a water tank, an injection pipe, a first cleaning spray pipe, a cleaning brush, an electric rotating rod, an impeller, an air compressor, a first delivery pipe, a second delivery pipe, a third delivery pipe, a micro pump, a fourth delivery pipe, a second cleaning spray pipe, a first electric valve, and a second electric valve. The water tank is fixedly installed on one side of the assembly platform, the injection pipe is fixedly installed on one end of the water tank, one end of the first cleaning spray pipe is connected to the outer frame of the assembly platform, the first cleaning spray pipe is C-shaped, and the other end of the first cleaning spray pipe extends to one side of the assembly placement plate.

[0009] The present invention further illustrates that a mounting base is provided on the outer wall of the first cleaning nozzle, and both ends of the cleaning brush are rotatably mounted on the mounting base on the outer wall of the first cleaning nozzle. One end of the electric rotating rod passes through the first cleaning nozzle and is connected to the rotating shaft of the cleaning brush, and the impeller is detachably mounted on the other end of the electric rotating rod.

[0010] The present invention further illustrates that one end of the third delivery pipe is connected to the water tank, and the other end is connected to one end of the fourth delivery pipe, and the micro pump is detachably installed on the third delivery pipe.

[0011] The present invention further illustrates that the second cleaning nozzle is disposed on one side of the collection tank, one end of the fourth conveying pipe is connected to the third conveying pipe, and the other end passes through the assembly table and is connected to the second cleaning nozzle.

[0012] The present invention further illustrates that the air compressor is detachably installed on the outside of the water tank, one end of the first delivery pipe is connected to the air compressor, and the other end is connected to the third delivery pipe.

[0013] The present invention further illustrates that the first electric valve is disposed at one end inside the third conveying pipe, and the second electric valve is disposed at the other end inside the third conveying pipe.

[0014] It also includes the following steps:

[0015] S1. When the equipment program detects that the dimensions of the permanent magnet synchronous direct drive motor are A1 and A2, the equipment program controls the air compressor to start, the pumping value is X1, the first electric valve is opened, the second electric valve is closed, the electric rotary rod is unlocked, the air compressor blows compressed air into the first conveying pipe, then through the third conveying pipe into the second conveying pipe, and finally into the first cleaning nozzle and sprays it outward to the surface of the permanent magnet synchronous direct drive motor, blowing away the dust and debris generated during assembly on the surface of the permanent magnet synchronous direct drive motor. At the same time, the compressed air flowing in the first cleaning nozzle blows the impeller to rotate, the impeller drives the electric rotary rod to rotate, the electric rotary rod drives the cleaning brush to rotate, and the cleaning brush brushes away the debris and dust in the gaps on the surface of the permanent magnet synchronous direct drive motor, making it easier for the staff to pack and transport it later.

[0016] S2. When the equipment program detects that the size of the permanent magnet synchronous direct drive motor is A3, the equipment program controls the air compressor to adjust the pumping value to X2, the first electric valve opens, the second electric valve is closed, the electric rotary rod is unlocked, the air compressor blows compressed air into the first conveying pipe, then through the third conveying pipe into the second conveying pipe, and finally into the first cleaning nozzle and sprays it outward onto the surface of the permanent magnet synchronous direct drive motor, blowing away the dust and debris generated during assembly on the surface of the permanent magnet synchronous direct drive motor. At the same time, the compressed air flowing in the first cleaning nozzle will blow the impeller to rotate, the impeller will drive the electric rotary rod to rotate, and the electric rotary rod will drive the cleaning brush to rotate. The cleaning brush will brush away the debris and dust in the gaps on the surface of the permanent magnet synchronous direct drive motor, making it easier for the staff to pack and transport it later.

[0017] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: The present invention, through the coordinated use of two sets of electric sliders, two sets of electric telescopic rods, an assembly placement plate, a camera, and equipment programs, can change the processing and assembly position according to the different sizes of permanent magnet synchronous direct drive motors, and at the same time change the moving and transporting speed during the assembly process. When assembling small-sized permanent magnet synchronous direct drive motors, the transport speed is reduced to avoid displacement of the permanent magnet synchronous direct drive motor during assembly and transport, which would affect subsequent operations. At the same time, the position of the assembly placement plate is raised so that the permanent magnet synchronous direct drive motor is closer to the first cleaning nozzle and the assembly robot, reducing energy consumption during the assembly process. When assembling large-sized permanent magnet synchronous direct drive motors, the transport speed is increased to ensure assembly efficiency, while the position of the assembly placement plate is lowered to avoid damage caused by the large-sized permanent magnet synchronous direct drive motor hitting the first cleaning nozzle during movement, thus reducing factory maintenance costs.

[0018] By using an air compressor, a primary cleaning nozzle, and the equipment program in conjunction with the system, different levels of ventilation and cleaning operations can be performed on permanent magnet synchronous direct drive motors of various sizes. This removes residual dust and debris from the surface of the motor. The electric rotary rod, impeller, cleaning brush, and the equipment program work together to simultaneously blow away dust and debris while using compressed air to rotate the cleaning brush, removing dust and debris from the crevices on the motor surface. This improves cleaning efficiency and facilitates subsequent packaging and transportation. A secondary cleaning of the permanent magnet synchronous direct drive motor surface can be performed using a micro pump, two sets of electric valves, and the equipment program. This washes away residual stains and protects the coating. The cleaning brush can also be locked to prevent the maintenance solution from splashing everywhere and affecting the workshop production environment, thus reducing the cleaning burden on staff.

[0040] The assembly robot 21, two sets of electric sliders, two sets of electric telescopic rods, air compressor 34, micro pump 351, two sets of electric valves, camera 16, and electric rotating rod 331 are all connected to the equipment program signals.

[0041] Assembly operation of permanent magnet synchronous direct drive motor:

[0042] After the production of the permanent magnet synchronous direct drive motor 4 is completed, the staff assembles its casing. First, the staff uses a transport vehicle to move the permanent magnet synchronous direct drive motor 4 to the production workshop. Then, the staff turns on the workshop power, and the assembly table 1 starts, along with the equipment program. The program first detects the position of the assembly placement plate 22 using camera 16, and then controls two sets of electric sliders to move along two sets of sliding rails. When the assembly placement plate 22 moves to one end of the two sets of sliding rails, the program controls the two sets of electric sliders to stop. At this point, the staff uses a hoisting tool to place the permanent magnet synchronous direct drive motor 4 onto the assembly placement plate 22. After the permanent magnet synchronous direct drive motor 4 is placed, the program uses camera 16 to detect the dimensions of the permanent magnet synchronous direct drive motor 4 and compares them with the set values. The program sets the dimensions to A1, A2, and A3, where A1 is the minimum and A3 is the maximum, which can be adjusted according to specific needs. The extension values ​​of the two sets of electric telescopic rods are B1, B2, and B3, where B1 is the minimum and B3 is the maximum. The movement speeds of the two sets of electric sliders are C1, C2, and C3, where C1 is the minimum and C3 is the maximum. When the equipment program detects that the size of the permanent magnet synchronous direct drive motor 4 is A1, the equipment program determines that the motor size is small. The equipment program first controls the two sets of electric sliders to start, with a movement speed of C1. The two sets of moving sliders drive the assembly placement plate 22 to move slowly along the direction of the two sets of moving slide rails. At this time, the equipment program detects the position of the assembly placement plate 22 through the camera 16. When the assembly placement plate 22 moves to the first cleaning nozzle 32, the equipment program controls the two sets of electric sliders to stop. The equipment program controls the two sets of electric telescopic rods to start, with an extension value of B3. The two sets of electric telescopic rods rise to the maximum value and drive the assembly placement plate 22 to move upward. The assembly placement plate 22 drives the permanent magnet synchronous direct drive motor 4 to move upward to one side of the first cleaning nozzle 32. At this time, the equipment program controls the assembly robot 21 to operate and perform the shell assembly operation on the permanent magnet synchronous direct drive motor 4.

[0043] When the device program detects that the size of the permanent magnet synchronous direct drive motor 4 is A2, the device program determines that the motor size has increased. The device program first controls the two sets of electric sliders to start, with a moving speed of C2. The two sets of moving sliders drive the assembly placement plate 22 to move along the direction of the two sets of moving slide rails. At this time, the device program detects the position of the assembly placement plate 22 through the camera 16. When the assembly placement plate 22 moves to the first cleaning nozzle 32, the device program controls the two sets of electric sliders to stop. The device program controls the two sets of electric telescopic rods to start, with an extension value of B2. The two sets of electric telescopic rods rise up and drive the assembly placement plate 22 to move upward. The assembly placement plate 22 drives the permanent magnet synchronous direct drive motor 4 to move upward to one side of the first cleaning nozzle 32. At this time, the device program controls the assembly robot 21 to operate and perform the shell assembly operation on the permanent magnet synchronous direct drive motor 4.

[0044] When the equipment program detects that the size of the permanent magnet synchronous direct drive motor 4 is A3, the equipment program determines that the motor size is too large. The equipment program first controls the two sets of electric telescopic rods to start, with an extension value of B1. The two sets of electric telescopic rods rise to the minimum value and drive the assembly placement plate 22 to move upward. The assembly placement plate 22 drives the permanent magnet synchronous direct drive motor 4 to move upward to the minimum value. Then the equipment program controls the two sets of electric sliders to start, with a moving speed of C3. The two sets of moving sliders drive the assembly placement plate 22 to move along the direction of the two sets of moving slide rails. At this time, the equipment program detects the position of the assembly placement plate 22 through the camera 16. When the assembly placement plate 22 moves to the first cleaning nozzle 32, the equipment program controls the two sets of electric sliders to stop. At this time, the equipment program controls the assembly robot 21 to operate and perform the shell assembly operation on the permanent magnet synchronous direct drive motor 4. After completing the above operations, the equipment program controls the next operation.

[0045] By using two sets of electric sliders, two sets of electric telescopic rods, assembly placement plate 22, camera 16, and equipment program in conjunction with each other, the processing and assembly position of the permanent magnet synchronous direct drive motor 4 of different sizes can be changed, and the movement and transportation speed during the assembly process can be changed. When assembling small-sized permanent magnet synchronous direct drive motors 4, the transportation speed is reduced to avoid displacement of the permanent magnet synchronous direct drive motor 4 during assembly and transportation, which would affect subsequent operations. At the same time, the position of the assembly placement plate 22 is raised so that the permanent magnet synchronous direct drive motor 4 is closer to the first cleaning nozzle 32 and the assembly robot 21, reducing energy consumption during the assembly process. When assembling large-sized permanent magnet synchronous direct drive motors 4, the transportation speed is increased to ensure assembly efficiency, while the position of the assembly placement plate 22 is lowered to prevent the large-sized permanent magnet synchronous direct drive motor 4 from colliding with the first cleaning nozzle 32 during movement, which would cause damage and reduce factory maintenance costs.

[0046] Assembly ventilation and cleaning operations:

[0047] After completing the above operations, the equipment program controls the assembly ventilation and cleaning operation. The equipment program adjusts the degree of ventilation and cleaning according to the different sizes of the permanent magnet synchronous direct drive motor 4. The equipment program sets the pumping value of the air compressor 34 to X1 and X2, where X1 is the minimum and X2 is the maximum, and can be adjusted according to specific needs. The pumping volume of the micro pump 351 is set to Y1 and Y2, where Y1 is the minimum and Y2 is the maximum, and can be adjusted according to specific needs. When the equipment program detects that the size value of the permanent magnet synchronous direct drive motor 4 is A1 or A2, the equipment program controls the air compressor 34 to start, the pumping value is X1, the first electric valve 36 is opened, and the second electric valve 361 is closed. With the electric rotary rod 331 in the unlocked state, the air compressor 34 blows compressed air into the first conveying pipe 341, then through the third conveying pipe 35 into the second conveying pipe 342, and finally into the first cleaning nozzle 32, spraying it outwards onto the surface of the permanent magnet synchronous direct drive motor 4. This removes residual dust and assembly debris from the surface of the permanent magnet synchronous direct drive motor 4. At the same time, the compressed air flowing in the first cleaning nozzle 32 blows the impeller 332 to rotate, which in turn drives the electric rotary rod 331 to rotate. The electric rotary rod 331 then drives the cleaning brush 33 to rotate, which brushes away debris and dust from the gaps on the surface of the permanent magnet synchronous direct drive motor 4, making it easier for staff to pack and transport it later.

[0048] When the equipment program detects that the size of the permanent magnet synchronous direct drive motor 4 is A3, the equipment program controls the air compressor 34 to adjust the pumping value to X2, the first electric valve 36 is opened, the second electric valve 361 is closed, the electric rotary rod 331 is unlocked, the air compressor 34 blows compressed air into the first conveying pipe 341, then through the third conveying pipe 35 into the second conveying pipe 342, and finally into the first cleaning nozzle 32 and sprays it outward onto the surface of the permanent magnet synchronous direct drive motor 4, blowing away the dust and debris generated during assembly on the surface of the permanent magnet synchronous direct drive motor 4. At the same time, the compressed air flowing in the first cleaning nozzle 32 blows the impeller 332 to rotate, the impeller 332 drives the electric rotary rod 331 to rotate, the electric rotary rod 331 drives the cleaning brush 33 to rotate, and the cleaning brush 33 brushes away the debris and dust in the gaps on the surface of the permanent magnet synchronous direct drive motor 4, making it easier for the staff to pack and transport it later.

[0049] After completing the above operations, the equipment program controls the spraying of maintenance fluid. When the equipment program detects that the size value of the permanent magnet synchronous direct drive motor 4 is A1 or A2, the equipment program controls the air compressor 34 to start, the pumping air value is X1, the micro pump 351 to start, the pumping water volume is Y1, the first electric valve 36 is opened, the second electric valve 361 is closed, the electric rotary rod 331 is locked, the air compressor 34 blows compressed air into the first delivery pipe 341, and then blows it into the second delivery pipe 342 through the third delivery pipe 35. The micro pump 351 pumps the maintenance fluid in the water tank 31 into the third delivery pipe 35. After the maintenance fluid is mixed with the compressed air, it is blown into the first cleaning spray pipe 32 and sprayed outwards onto the surface of the permanent magnet synchronous direct drive motor 4 to clean the stains remaining on the surface of the permanent magnet synchronous direct drive motor 4 and perform maintenance coating at the same time. At this time, the electric rotary rod 331 is locked and the impeller 332 will not rotate, which can prevent the cleaning brush 33 from rotating and causing the maintenance fluid to splash everywhere and affect the workshop production environment.

[0050] When the equipment program detects that the size of the permanent magnet synchronous direct drive motor 4 is A3, the equipment program controls the air compressor 34 to start, the pumping air value is X2, the micro pump 351 to start, the pumping water volume is Y2, the first electric valve 36 is opened, the second electric valve 361 is closed, the electric rotary rod 331 is locked, the air compressor 34 blows compressed air into the first delivery pipe 341, and then blows it into the second delivery pipe 342 through the third delivery pipe 35. The micro pump 351 pumps the maintenance fluid in the water tank 31 into the third delivery pipe 35. After the maintenance fluid is mixed with the compressed air, it is blown into the first cleaning spray pipe 32 and sprayed outward onto the surface of the permanent magnet synchronous direct drive motor 4 to clean the stains remaining on the surface of the permanent magnet synchronous direct drive motor 4 and perform maintenance coating at the same time. At this time, the electric rotary rod 331 is locked and the impeller 332 will not rotate, which can prevent the cleaning brush 33 from rotating and causing the maintenance fluid to splash everywhere and affect the workshop production environment.

[0051] The maintenance liquid generated by spraying will flow down into the assembly placement plate 22, then down into the collection tank 14, and finally out from the discharge pipe 15 to the workshop recycling device for centralized collection. When it is necessary to clean the collection tank 14, the equipment program controls the second electric valve 361 to open while performing the above maintenance liquid spraying operation. The maintenance liquid will flow from the third delivery pipe 35 into the fourth delivery pipe 352, and finally be sprayed out from the second cleaning spray pipe 353 into the collection tank 14 to clean the waste liquid residue in the collection tank 14, so as to avoid the excessive waste liquid residue from causing the assembly table 1 to rust and be damaged.

[0052] By using the air compressor 34, the first cleaning nozzle 32, and the equipment program in conjunction with the equipment, different degrees of ventilation and cleaning operations can be performed on permanent magnet synchronous direct drive motors 4 of different sizes. This blows away residual dust and debris on the surface of the permanent magnet synchronous direct drive motor 4. By using the electric rotating rod 331, the impeller 332, the cleaning brush 33, and the equipment program in conjunction with the equipment, the cleaning brush 33 can be rotated by compressed air while blowing away debris and dust. This brushes away dust and debris from the gaps on the surface of the permanent magnet synchronous direct drive motor 4, improving cleaning efficiency and facilitating subsequent packaging and transportation by the staff. By using the micro pump 351, two sets of electric valves, and the equipment program in conjunction with the equipment, a secondary cleaning can be performed on the surface of the permanent magnet synchronous direct drive motor 4, rinsing away residual stains on the surface of the permanent magnet synchronous direct drive motor 4. This also protects the coating and locks the cleaning brush 33 to prevent it from rotating and causing the maintenance liquid to splash everywhere, affecting the workshop production environment and reducing the cleaning burden on the staff.
