Description

Technical Field

[0001] The present invention relates to the technical field of motor assembly, and particularly to a permanent magnet synchronous motor rotor magnet assembly device. Background Art

[0002] A permanent magnet synchronous motor is a type of motor with high efficiency, energy conservation, and excellent performance. Its working principle 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 can generate a strong magnetic field during rotation, thereby providing a greater output torque. The control system of the motor precisely adjusts the current to ensure that the motor rotor can rotate synchronously with the rotating magnetic field and maintain a stable operating state.

[0003] With the continuous progress of technology, the advantages of permanent magnet synchronous motors in energy conservation, emission reduction, and high efficiency have made them an important development direction for future motor technology. Especially in the fields of new energy vehicles and renewable energy, their application prospects are broad.

[0004] When assembling magnets on the rotor of a large permanent magnet synchronous motor, manual installation is one method. However, before installing the magnets, it is necessary to manually add anaerobic glue inside the placement groove, and then insert the magnets into the iron core. When manually adding anaerobic glue, it is impossible to accurately control the amount of anaerobic glue. Excessive anaerobic glue will form a thick glue layer on the bonding surface, affecting the close contact of the bonding surface, thereby reducing the bonding strength and sealing effect. At the same time, it will cause a large waste of anaerobic glue.

[0005] Therefore, it is necessary to provide a permanent magnet synchronous motor rotor magnet assembly device to solve the above technical problems. Summary of the Invention

[0020] Compared with the related art, the permanent magnet synchronous motor rotor magnetic steel assembly equipment provided by the present invention has the following beneficial effects:

[0021] 1. The present invention provides a permanent magnet synchronous motor rotor magnetic steel assembly equipment. Through the setting of the assembly mechanism, when in use, the first cylinder moves up and down, thereby driving the lower encapsulation part, glue injection part and adjustment part to work synchronously. And the working trajectory of the first cylinder drives the liquid extraction rod to quantitatively extract the anaerobic glue inside the placement barrel, realizing the quantitative addition of anaerobic glue inside the placement cavity, thereby accurately controlling the amount of anaerobic glue used, avoiding a large waste of anaerobic glue, and the excessive use of anaerobic glue affecting the bonding strength of the magnetic steel bonding surface.

[0022] 2. The present invention provides a permanent magnet synchronous motor rotor magnetic steel assembly equipment. By driving the encapsulation part, glue injection part and adjustment part to work synchronously by the first cylinder, the anaerobic glue is sequentially injected into different placement cavities on the motor rotor and the magnetic steel is assembled. And the processes are directly controlled by the first cylinder, thereby greatly reducing the number of electrical components and the corresponding power system used, and correspondingly reducing the maintenance cost of the entire equipment.

[0023] 3. The present invention provides a permanent magnet synchronous motor rotor magnetic steel assembly equipment.

When the placement block moves downward, it drives the outer support rod three to move outward. When the support rod three moves outward, the lower support rods one and two move outward synchronously, so that the support rods one, two and three jointly move the pressing plate outward, making the pressing plate fix the motor rotor, thereby being able to quickly install and fix the motor rotor.

[0044] The packaging member 71 includes a first cylinder 710, the first cylinder 710 is fixedly installed on the fixing table 6, a placement plate 711 is fixedly installed at the output end of the first cylinder 710, the top of the liquid extraction rod 726 is fixedly connected to one side of the placement plate 711, a plug-in plate 712 is fixedly installed at the bottom of the placement plate 711, a plug-in block 713 is fixedly installed at the bottom of the plug-in plate 712, a placement member 8 is arranged on one side of the connecting block 21, a magnet 803 is placed inside the placement member 8, and the plug-in block 713 is arranged above the magnet 803. Specifically, when the first cylinder 710 works, the output end extends downward, thereby driving the placement plate 711 to move downward. When the placement plate 711 moves downward, it will drive the lower plug-in plate 712 and plug-in block 713 to move downward, thereby stamping the lower magnet 803 and pushing the lower magnet 803 into the placement cavity 22. After the stamping is completed, then the first cylinder 710 retracts upward, thereby driving the bottom placement plate 711 to move upward.

When the second pull rod 76 moves upward, it will drive the guide cylinder 739 above to move upward synchronously.

A clamping plate 809 is fixedly installed on the top of the guide plate 810. A push rod 808 is fixedly installed on one side of the clamping plate 809. A push plate 804 is fixedly installed on one side of the push rod 808. One side of the push plate 804 is in contact with the magnet 803. The operator pulls the push plate 804 outwards, then places the magnet 803 inside the placement frame 801 and sorts the magnet 803 as needed. After placement, the return spring 807 retracts, thereby pulling the slider 811 to slide on the outer side of the sliding rod 806, so that the push plate 804 squeezes and pushes the magnet 803, facilitating the placement of the magnet 803.

[0049] The working principle of the permanent magnet synchronous motor rotor magnet assembly equipment provided by the present invention is as follows:

[0050] First step: When assembling the magnet 803 on the motor rotor 12, place the motor rotor 12 on the limiting member, and the first cylinder 710 works and retracts backward, thereby driving the upper placement block 31 to move downward. When the placement block 31 moves downward, it drives the outer support rod three 32 to move outward. When the support rod three 32 moves outward, the lower support rod one 27 and the support rod two 29 move outward synchronously, so that the support rod one 27, the support rod two 29 and the support rod three 32 jointly move the extrusion plate 23 outward, so that the extrusion plate 23 fixes the motor rotor 12.

[0051] After the fixation is completed, the operator injects anaerobic glue into the interior of the placement cavity 22 below the placement frame 801, and then the electric telescopic rod 2 retracts downward, driving the upper connecting platform 4 to move downward. When the connecting platform 4 moves downward, the first pull rod 74 will extend into the connector 75, and the connector 75 fixes the first pull rod 74 and the second pull rod 76.

[0052] Then the operator pulls the push plate 804 outward, places the magnet 803 inside the placement frame 801, sorts the magnet 803 as needed. After the placement is completed, the return spring 807 retracts, pulling the slider 811 to slide outside the slide rod 806, so that the push plate 804 squeezes and pushes the magnet 803.

[0053] Step 2: After the magnet 803 is placed, assemble the magnet 803. The first cylinder 710 works, and the output end extends downward, driving the placement plate 711 to move downward. When the placement plate 711 moves downward, it drives the lower plug-in board 712 and the plug-in block 713 to move downward, stamping the lower magnet 803 and pushing the lower magnet 803 into the placement cavity 22.

[0054] When the placement plate 711 moves downward, it synchronously drives the liquid extraction rod 726 on one side to move downward. When the liquid extraction rod 726 moves downward, it pushes the lower liquid extraction head 727 to move downward, squeezing the anaerobic glue inside the liquid extraction cylinder 725 downward. The check valve two 729 at the bottom of the liquid extraction cylinder 725 automatically opens, and the anaerobic glue is squeezed into the lower placement cavity 22 through the extrusion pipe 724.

[0055] When the placement plate 711 drives the liquid extraction rod 726 to move downward, it drives the first pull rod 74 and the second pull rod 76 on the other side to move downward synchronously. When the second pull rod 76 moves downward, it drives the bottom guide cylinder 739 to move downward inside the rotating cylinder 733, making the limit post 735 move downward inside the guiding groove 737.

[0056] Then the first cylinder 710 retracts upward, driving the bottom placement plate 711 to move upward. When the placement plate 711 moves upward, it drives the bottom plug-in board 712 and the plug-in block 713 to move upward. When the placement plate 711 moves upward, the liquid extraction rod 726 on one side moves upward. When the liquid extraction rod 726 moves upward, it drives the lower liquid extraction head 727 to move upward inside the liquid extraction cylinder 725. When the liquid extraction head 727 moves upward, the check valve one 728 on one side opens, extracting the anaerobic glue inside the placement barrel 721 through the delivery pipe 723. When the first cylinder 710 works up and down, automatic injection of anaerobic glue is achieved.

[0057] When the placement plate 711 moves upward, it will synchronously drive the pull rod 74 and the pull rod 76 on the other side to move upward. When the pull rod 76 moves upward, it will drive the guide cylinder 739 above to move upward synchronously. When the guide cylinder 739 moves, it will drive the outer limit post 735 to move upward inside the guiding groove 737. When the limit post 735 moves upward into the extrusion groove 738, it will drive the rotating cylinder 733 to rotate through the guiding wire of the extrusion groove 738. When the rotating cylinder 733 rotates, it will drive the outer rotating wheel 734 to rotate. When the rotating wheel 734 rotates, it will drive the rotating wheel 26 to rotate through the belt 9. When the rotating wheel 26 rotates, it will drive the top rotating seat 25 to rotate on the stabilizing platform 11, thereby driving the upper motor rotor 12 to rotate, realizing the synchronous movement of the position of the motor rotor 12, and realizing the sequential filling of anaerobic glue and the assembly of the magnetic steel 803 in different placement cavities 22.

[0058] Compared with the related technology, the permanent magnet synchronous motor rotor magnetic steel assembly equipment provided by the present invention has the following beneficial effects:

[0059] 1. The present invention provides a permanent magnet synchronous motor rotor magnetic steel assembly equipment. Through the setting of the assembly mechanism 7, during use, the cylinder 710 moves up and down, thereby driving the lower encapsulation part 71, the glue injection part 72 and the adjustment part 73 to work synchronously. And the working trajectory of the cylinder 710 drives the liquid extraction rod 726 to quantitatively extract the anaerobic glue inside the placement barrel 721, realizing the quantitative addition of anaerobic glue inside the placement cavity 22, thereby accurately controlling the amount of anaerobic glue used, avoiding a large waste of anaerobic glue, and the excessive use of anaerobic glue affecting the bonding strength of the bonding surface of the magnetic steel 803.

[0060] 2. The present invention provides a permanent magnet synchronous motor rotor magnetic steel assembly equipment. Through the cylinder 710 driving the encapsulation part 71, the glue injection part 72 and the adjustment part 73 to work synchronously, the anaerobic glue is sequentially filled and the magnetic steel 803 is assembled in different placement cavities 22 on the motor rotor 12. And the processes are directly controlled by the cylinder 710, thereby greatly reducing the number of electrical components and the corresponding power system used, and correspondingly reducing the maintenance cost of the entire equipment.

Specifically, the motor rotor 12 is placed on the limiting member, and the second cylinder 30 works and retracts backward, thereby driving the upper placement block 31 to move downward. When the placement block 31 moves downward, it drives the outer third support rod 32 to move outward. When the third support rod 32 moves outward, the lower first support rod 27 and the second support rod 29 move outward synchronously, so that the first support rod 27, the second support rod 29 and the third support rod 32 jointly move the pressing plate 23 outward, so that the pressing plate 23 fixes the motor rotor 12, so that the motor rotor 12 can be quickly installed and fixed.

A belt 9 is sleeved outside the first runner 734 and the second runner 26. The first runner 734 and the second runner 26 are rotationally connected by the belt 9. When in use, when the placement plate 711 moves upward, it will synchronously drive the other side's first pull rod 74 and the second pull rod 76 to move upward. When the second pull rod 76 moves upward, it will drive the upper guide cylinder 739 to move upward synchronously. When the guide cylinder 739 moves, it will drive the outer limiting column 735 to move upward inside the guiding groove 737. When the limiting column 735 moves upward into the extrusion groove 738, it drives the rotating cylinder 733 to rotate through the guiding line of the extrusion groove 738. When the rotating cylinder 733 rotates, it drives the outer first runner 734 to rotate. When the first runner 734 rotates, it drives the second runner 26 to rotate through the belt 9.
