[0023] The integrated magnetic steel module, the dispensing and handling module, the magnetic steel pressure holding and positioning fixture, and the turnover module are all installed on the installation platform 1; The spraying mechanism includes a sealed box 4, a conveyor frame 5, and a spray valve.

The sealed box 4 is used to prevent the accelerator from escaping. The material distribution mechanism includes a horizontally sliding movable seat 6, a frame 7, a tilting seat 8, a material distribution box 9, and a conveyor frame 10. The frame 7 is located on the movable seat 6 and is horizontally rotatably connected to it. The inner wall of the frame 7 is rotatably connected to the tilting seat 8 through a rotating shaft. The material distribution box 9 is horizontally slidably connected to the tilting seat 8. The mounting platform 1 is symmetrically equipped with a slide rail 1 for the horizontal sliding of the movable seat 6. A pushing component is fixedly installed on the tilting seat 8 to push the material distribution box 9 to the end of the conveyor frame 5, so that the conveyor frame 5 can transport the magnet into the material distribution box 9. The bottom of the frame 7 is equipped with a drive wheel, which is connected to the rotating shaft on the tilting seat 8 through a synchronous belt. When the conveyor frame 5 transports the magnet into the material distribution box 9, it is synchronized by the sensor on the top of the conveyor frame 5. The pushing component pushes the material distribution box 9 away from the conveyor frame 5, the movable seat 6 moves vertically along the conveyor frame 5, and the frame 7 rotates 90 degrees on the movable seat 6. As the movable seat 6 moves, the material distribution box 9 moves to the top of the conveyor frame 10. The tilting seat 8 is driven by the drive motor to rotate, so that the material distribution box 9 is tilted and distributed into the conveyor frame 10.

[0024] The second conveyor frame 10 is symmetrically arranged at both ends of the first conveyor frame, and each end of the second conveyor frame 10 is equipped with a corresponding magnet integrated module. By moving the first movable seat 6, the magnets can be transported from the first conveyor frame 5 to the two corresponding conveyor frames and integrated through the magnet integrated module.

[0025] The magnet integrated module includes two symmetrically arranged movable seats 11. The two movable seats 11 are located on both sides of the magnet integrated handling module and are horizontally slidably connected to the mounting platform 1. An integrated disk 12 driven by a servo motor is rotatably connected to the movable seat 11. A positioning module 13 is inserted into the integrated disk 12. The positioning module 13 has a ring array of positioning slots on its surface for positioning the magnets. When the magnets on the conveyor frame 10 move to the designated position, they are pushed one by one by the pneumatic components to unload. As the integrated disk 12 rotates, the unloading position is switched and the magnets fall into the corresponding positioning slots. The installation platform 1 is equipped with a slide rail 2 for the horizontal sliding of the integrated magnet module. Two movable seats 2 11 move along the slide rail 2 and move to the bottom of the integrated magnet handling module for handling. The integrated magnetic steel handling module includes a fixed frame 14, a lead screw component, and a handling assembly 15 located on the mounting platform 1. The handling assembly 15 is located on the fixed frame 14 and is horizontally slidably connected to the fixed frame 14.

The bottom of the conforming magnetic steel suction head 17 has a slot corresponding to the magnetic steel, and the inner walls of the slot have micropores for adsorption. The vacuum generator 16 is connected to the conforming magnetic steel suction head 17 through a pipe and uses the channel to cooperate with the micropores to adsorb the magnetic steel. The lead screw is driven to rotate under the action of the servo motor 2, which drives the handling assembly 15 to move. As the handling assembly 15 slides on the fixed frame 14, the conforming magnetic steel suction head is set on the moving seat 5, and the conforming magnetic steel suction head 17 moves in the vertical direction to handle the integrated magnetic steel.

[0026] The dispensing and handling module includes a second fixed frame 18 and a third fixed frame 19 located on the mounting platform 1. A dispensing device 28 is horizontally slidably connected to the second fixed frame 18. A handling mechanism for handling the rotor core is fixedly connected to the third fixed frame 19. A detection platform is set on one side of the handling mechanism. A movable seat 20 is slidably connected to one side of the turnover module. A flipping platform 21 is rotatably connected to the movable seat 20. A motor-driven rotating seat is rotatably connected to the flipping platform 21. The rotating seat places and fixes the rotor core. The rotating platform is vertically rotatably connected to the moving seat 3 20 via a rotating shaft. The rotation of the rotating platform is used to switch the adhesive adhesion surface of the rotor core. When the moving seat 3 20 moves towards the conveying mechanism, the conveying mechanism fixes the rotor core and transports it to the inspection platform for inspection. The inspection platform is equipped with a conveyor belt, and the adhesive effect is confirmed by taking pictures through a camera vision system. If the adhesive treatment is not qualified, it is discharged away from the rotating seat. When it is qualified, it is moved into the pressure holding fixture by the conveying mechanism.

[0027] The magnet pressure-holding and positioning fixture includes a support base 22 and a pressure-holding plate 23. The pressure-holding plate 23 is used to hold and pressure the iron core and magnet. The pressure-holding plate 23 is fixed on the support base 22. The pressure-holding plate 23 has an annular base surface for placing the magnet. A cylindrical protrusion for placing the iron core is provided at the center of the annular base surface. The pressure-holding plate 23 has a positioning groove, and a pressure plate for positioning the magnet is elastically connected in the positioning groove. The turnover module includes a horizontally arranged conveyor platform 24, on which the magnetic steel pressure-holding and positioning fixture is located. At the end of the turnover module, there is a turnover platform 25 for the magnetic steel pressure-holding and positioning fixture to wait. Two symmetrically arranged conveyor platforms are set on the turnover platform 25. A pressure-holding and transporting mechanism is set on one side of the conveyor platform 2. The pressure-holding and transporting mechanism includes a fixed frame 26, a movable seat 27, and a transporting gripper, which is used to transport the magnetic steel pressure-holding and positioning fixture to the turnover area for waiting to be fixed and cured. Furthermore, the precise movement of the aforementioned components in the horizontal and vertical directions can be achieved by using components such as lead screws for transmission drive, thereby conveying precise positional movement.

[0028] The movable seat 4 27 is horizontally slidably mounted on the fixed frame 4 26. The transport gripper is vertically slidably connected to the movable seat 4 27. When the movable seat 4 27 moves horizontally, the transport gripper moves to the top of the magnetic steel pressure-holding positioning fixture. The transport gripper moves vertically to clamp the magnetic steel pressure-holding positioning fixture and then moves again to the turnover platform 25 via the movable seat 4 27. The turnover platform 25 can be a ring conveyor track. A fan is installed on the top of the turnover platform 25 to accelerate the air flow and quickly solidify the magnets and rotor core.

[0029] A method for rapid bonding of permanent magnets in an electric motor rotor includes the following specific steps: S1, Magnet screening: The magnets to be processed are conveyed to the vibratory plate 2. The vibratory plate 2 uses vibration to screen and convey the qualified magnets to the conveyor frame 5 of the spraying mechanism according to the preset posture. S2, Magnet interface optimization: Conveyor frame 5 sends the magnet into the sealed box 4, the spray valve opens, and the accelerator is precisely sprayed onto the magnet on conveyor frame 5. After spraying, conveyor frame 5 transports the magnet to the end of the distribution mechanism. S3, magnetic steel material distribution and conveying, the material distribution box 9 moves to the end of the conveyor frame 1 5, the material distribution box 9 resets, the moving seat 1 6 moves, and at the same time the frame 7 rotates on the moving seat 1 6 to align the material distribution box 9 with the symmetrically arranged conveyor frame 2 10, so that the material distribution box 9 is tilted and the magnetic steel is poured into the corresponding conveyor frame 2 10, realizing multi-station material distribution with single-path entry and double-path exit. S4, magnet integration, conveyor frame 2 10 conveys the magnet to the end magnet integration module; pneumatic components push the magnet into the annular array positioning slot of positioning module 13, servo motor 1 drives the integration disk 12 to rotate until the positioning slot is completely filled with magnets, completing the integration of a single set of magnets, and the moving seat 2 11 moves along slide rail 2 to directly below the magnet integration transport module, waiting for the magnet to be transported; S5, core positioning and glue application surface switching: the movable seat 20 on one side of the turnover module moves along the slide rail and sends the rotating seat of the flipping platform 21 to the core loading position. The rotor core is placed on the rotating seat and fixed. The motor drives the rotating seat to adjust the core posture. At the same time, the flipping platform 21 rotates vertically through the rotating shaft to switch the bonding surface of the core that needs glue application. S6, the magnetic steel core is pressure-held and positioned. The moving seat 3 20 drives the iron core to move towards the dispensing and transporting module. The dispensing device 28 on the fixed frame 2 18 slides horizontally and accurately applies glue to the bonding surface of the iron core. The transporting mechanism of the fixed frame 3 19 adsorbs and clamps the iron core and transports it to the testing platform. The transporting mechanism clamps the qualified iron core and sends it to the magnetic steel pressure-held and positioning fixture. S7, the pressure-holding fixture is rotated and accelerated to cure. The magnet falls into the annular base and adheres to the bonding surface of the iron core. The elastic pressure plate in the positioning groove of the pressure-holding plate 23 automatically presses the magnet. The conveying platform 1 24 of the turnover module drives the magnet pressure-holding positioning fixture to the turnover platform 25. The transport gripper descends vertically to hold the pressure-holding fixture, and then moves with the moving seat 4 27 to the conveying platform 2 of the turnover platform 25 to wait for curing to be completed.

[0030] The working principle and usage process of this invention: Multi-mechanism collaborative automation achieves a closed-loop process of "magnet pretreatment → iron core precision treatment → magnet-iron core positioning and bonding → pressure holding and accelerated curing," thereby improving the efficiency, accuracy, and reliability of permanent magnet bonding in motor rotors. Specifically, this is achieved through the coordinated functions of the following modules: The feed box 3 is used to transport the magnetic steel raw materials. The vibrating plate 2 uses vibration to screen and remove the magnetic steel that does not meet the size / shape requirements. Only the qualified magnetic steel is transported to the subsequent stage in a preset posture, so as to ensure the consistency of raw materials from the source. Open the spray valve inside the sealed box 4 and spray the accelerator onto the qualified magnets on the conveyor frame 5. The sealed box 4 can prevent the accelerator from escaping and causing pollution. The accelerator can optimize the interfacial bonding performance between the magnet and the iron core, and at the same time accelerate the curing efficiency after subsequent bonding. The material distribution mechanism uses a combination of actions, including horizontal movement of the moving seat 6, rotation of the frame 7, and tilting of the flipping seat 8, to switch the magnets conveyed by a single path to two symmetrical conveying frames 10, thereby achieving a "single-in, double-out" multi-station allocation and improving subsequent integration efficiency. The magnets are conveyed by the second conveyor frame 10 and through the pneumatic components to the magnet integrated module. The positioning module 13 on the integrated plate 12 inserts and fixes the magnets through the annular array positioning groove. The second servo motor drives the integrated plate 12 to rotate in coordination with the pneumatic unloading, ensuring that the magnets form a uniform integrated shape according to the bonding requirements, in preparation for subsequent handling and bonding. The moving seat 20 drives the flipping platform 21 to move. After the rotating seat fixes the iron core, the flipping platform rotates vertically to switch the bonding surface of the iron core. The dispensing device 28 on the fixing frame 2 18 slides horizontally to accurately apply glue to the bonding surface of the iron core, ensuring that the glue coverage is uniform.

[0031] The handling mechanism delivers the glued iron core to the testing platform, where a camera vision system takes pictures to determine whether the glue application is leaking or whether the uniformity meets the standards. Unqualified iron cores are directly discharged, and only qualified iron cores enter the bonding process to avoid bonding failure due to glue application problems.

[0032] The pressure-holding plate 23 of the magnet pressure-holding and positioning fixture achieves coaxial positioning of the iron core and the integrated magnet through the structure of the central cylindrical protrusion positioning iron core and the annular base surface supporting the magnet; The integrated magnet handling module uses the conformal magnet suction head 17 to precisely place the integrated magnet on the annular base surface of the pressure plate and fit it against the bonding surface of the iron core. The elastic pressure plate in the positioning groove of the pressure plate 23 automatically presses the magnet to prevent it from shifting during the bonding process, ensuring the bonding accuracy between the magnet and the iron core and providing a stable pressure foundation for subsequent curing.

[0033] The first conveyor platform 24 of the turnover module transports the pressure-holding fixture carrying the magnet and iron core to the turnover platform 25. The pressure-holding and handling mechanism moves horizontally through the fourth moving seat 27 and holds vertically with the handling claws to transfer the fixture to the second conveyor platform of the turnover platform. The turnover platform has 25 optional circular conveyor tracks to achieve continuous turnover. The fan at the top of the platform accelerates airflow and speeds up the curing of the adhesive between the magnet and the iron core, shortening the overall production cycle and realizing continuous bonding and curing operations.

A method for rapid bonding of permanent magnets in a motor rotor, using the rapid bonding equipment for permanent magnets in a motor rotor as described in any one of claims 1-9, characterized in that, The specific steps include the following: S1, Magnet screening, the magnets to be processed are transported to the vibratory plate (2), the vibratory plate (2) uses vibration to screen and transport the qualified magnets to the conveyor frame (5) of the spraying mechanism in a preset posture. S2, Optimize the magnet interface. The first conveyor (5) sends the magnet into the sealed box (4). The spray valve is opened and the accelerator is precisely sprayed onto the magnet on the first conveyor (5). After the spraying is completed, the first conveyor (5) transports the magnet to the end of the material distribution mechanism. S3, magnet steel material distribution and conveying, the material distribution box (9) moves to the end of the conveyor frame one (5), the material distribution box (9) resets, the moving seat one (6) moves, and at the same time the frame body (7) rotates on the moving seat one (6), aligning the material distribution box (9) with the symmetrically arranged conveyor frame two (10), so that the material distribution box (9) tilts, and the magnet steel is poured into the corresponding conveyor frame two (10), realizing multi-station material distribution with single-path entry and double-path exit; S4, magnet integration, conveyor frame two (10) conveys the magnet to the end magnet integration module; pneumatic components push the magnet into the annular array positioning slot of the positioning module (13), servo motor drives the integration disk (12) to rotate until the positioning slot is completely filled with magnets, completing the integration of a single set of magnets, and the moving seat two (11) moves along slide rail two to directly below the magnet integration transport module, waiting for the magnet to be transported; S5, core positioning and glue application surface switching, the movable seat three (20) on one side of the turnover module moves along the slide rail one, and sends the rotating seat of the flipping platform (21) to the core loading position. The rotor core is placed on the rotating seat and fixed. The motor drives the rotating seat to adjust the core posture. At the same time, the flipping platform (21) rotates vertically through the rotating shaft to switch the bonding surface of the core that needs glue application. S6, the magnetic steel core is pressure-held and positioned, and the moving seat three (20) drives the iron core to move towards the dispensing and transporting module; the dispensing device (28) on the fixed frame two (18) slides in the horizontal direction and accurately applies glue to the bonding surface of the iron core; the transporting mechanism of the fixed frame three (19) adsorbs and clamps the iron core and transports it to the testing platform; the transporting mechanism clamps the qualified iron core and sends it to the magnetic steel pressure-held and positioning fixture. S7, the pressure holding fixture is rotated and accelerated to cure. The magnet falls into the annular base and is bonded to the iron core. The elastic pressure plate in the positioning groove of the pressure holding plate (23) automatically presses the magnet. The conveying platform one (24) of the turnover module drives the magnet pressure holding positioning fixture to the turnover platform (25). The transport gripper descends vertically to hold the pressure holding fixture, and then moves with the moving seat four (27) to the conveying platform two of the turnover platform (25) to wait for curing to be completed.
