Description

Technical Field

[0001] This utility model relates to the field of motor manufacturing technology, and more specifically, to a device for applying adhesive to the magnet of a motor. Background Technology

[0002] In the field of motor manufacturing, the magnet insertion process of the motor rotor core directly affects motor performance and production efficiency. Currently, the mainstream manual magnet insertion method suffers from high repetitive workload, low efficiency, and easy damage to the magnets due to improper operation. To overcome the limitations of manual operation, existing technologies have developed automated insertion equipment that uses a turntable mechanism in conjunction with a multi-station robotic arm. The robotic arm performs the insertion after the magnets in the hopper are separated by a material distribution mechanism. However, this type of equipment has revealed significant drawbacks in practical applications: due to the extremely strong magnetic attraction between the magnets, the traditional material distribution mechanism relies on a high-thrust cylinder to forcibly separate the magnets. This not only significantly increases equipment costs and reduces cylinder versatility, but also increases the risk of magnet breakage due to mechanical stress during the forceful pushing process, thus restricting the stability and production efficiency of automated equipment. Utility Model Content

[0003] The purpose of this invention is to overcome the defects in the prior art and provide a motor-inserted magnet gluing device that uses alternating magnetic steel spacers combined with a bidirectional material distribution structure to reduce the thrust required for magnetic steel separation, improve material distribution stability, reduce the risk of magnetic steel breakage, and achieve efficient material distribution.

[0004] To solve the above problems, this utility model provides a motor insert magnet gluing device, including an insert magnet gluing mechanism and a magnet supply mechanism. The magnet supply mechanism includes a loading platform and a loading mechanism, a guide seat with a guide groove, and a distribution seat with a distribution groove on the loading platform. The distribution groove is vertically connected to the rear end of the guide groove. A pushing mechanism is provided at the front end of the guide groove. The loading mechanism is horizontally or vertically set on the loading platform and has multiple rows of storage racks. Each row of storage racks has a magnet spacer arrangement group composed of alternating magnets and spacers. The loading mechanism is used to move the storage racks to the front opening of the guide groove. The pushing mechanism is used to drive the magnet spacer arrangement group from the storage racks along the guide groove to the distribution groove. A bidirectional pusher block is provided in the distribution groove through a bidirectional drive mechanism. When the bidirectional pusher block moves towards one end of the distribution groove, it is used to drive a single magnet to move towards one end of the distribution groove. When the bidirectional pusher block moves towards the other end of the distribution groove, it is used to drive a single spacer to move towards the other end of the distribution groove.

[0005] Compared with the prior art, the advantages of this utility model are as follows: This utility model uses a magnetic steel separator arrangement group composed of alternating magnets and separators. During the material conveying process in the guide trough, the separators physically isolate adjacent magnets, effectively weakening the direct magnetic attraction between magnets. This significantly reduces the thrust required for subsequent material separation processes, allowing the use of a general-purpose small-thrust cylinder to complete the separation action. This reduces equipment costs and avoids the risk of magnet breakage caused by strong thrust. The bidirectional push block and bidirectional drive mechanism in the material separation trough enable the magnets and separators to separate synchronously in opposite directions within the same material separation cycle. Combined with the vertical connection structure between the material separation trough and the guide trough, precise separation of magnets and separators is achieved, improving material separation efficiency while ensuring the continuity of the material separation action. The combined design of multiple rows of storage racks and a movable feeding mechanism enables continuous feeding of the magnetic steel separator arrangement group, reducing equipment downtime for material changes and providing a stable and reliable material supply foundation for the efficient coordination of automated magnet insertion and gluing processes.

[0006] As an improvement, the width of the material distribution trough is greater than the maximum of the thickness of a single magnet and the thickness of a single partition, but less than the sum of their thicknesses. A bidirectional pusher is positioned near the rear of the material distribution trough, and its width is less than or equal to the minimum of the thickness of a single magnet and the thickness of a single partition. With this structure, the width limitation of the material distribution trough, combined with the size constraint of the bidirectional pusher, ensures that the magnets and partitions can only move in a single-layer alternating arrangement within the trough. The width limitation of the bidirectional pusher ensures that it can only contact a single magnet or partition simultaneously. The reciprocating motion of the bidirectional pusher achieves precise directional separation of the magnets and partitions, avoiding stacking and jamming during the material pushing process and reducing the mechanical impact on the material during separation.

[0007] As an improvement, the front opening of the guide chute is equipped with a front guide port that gradually expands outward from back to front, and the rear opening of the guide chute is equipped with a rear guide port that gradually expands outward from front to back. With this structure, the flared guide ports at both ends of the guide chute allow the front guide port to smoothly guide the magnetic steel spacer assembly into the guide chute, while the rear guide port creates a smooth transition at the junction of the guide chute and the distribution chute. This allows the separated individual magnets or spacers to move and slide along the extension direction of the distribution chute into the corresponding distribution station, reducing the risk of material stagnation at the intersection of the guide chute and the distribution chute. Simultaneously, the outward expansion structure can compensate for minor positional deviations during material conveying, ensuring the alignment of the magnets and spacers before and after separation, and preventing material jamming or distribution failure due to misalignment.

[0008] As an improvement, the feeding mechanism includes a vertical frame fixed to the top of the feeding platform, a lifting seat slidably mounted on the frame via a first slider rail assembly, and a screw motor assembly fixed to the frame for driving the lifting seat up and down. The frame is distributed front and rear at the front end of the guide chute, and multiple rows of storage racks are fixed vertically at intervals on one side plate of the lifting seat. With this structure, the screw motor-driven lifting seat, in conjunction with multiple rows of vertically distributed storage racks, achieves precise layer-by-layer positioning of magnetic steel partitions of different heights. The lifting motion moves empty storage racks out of the workstation and full storage racks into the front end of the guide chute, ensuring continuous material supply and significantly reducing downtime for material changes.

[0009] As an improvement, the feeding mechanism includes linear drive modules fixedly mounted on the loading platform at the front and rear, and a top block fixed on the movable block of the linear drive module. The storage rack is arranged parallel to the front of the linear drive module, and the guide chute is arranged parallel to the rear of the linear drive module. With this structure, the linear motion paths of the linear drive module and the top block are arranged parallel to the storage rack and the guide chute, ensuring that the feeding direction of the top block is consistent with the moving direction of the magnetic steel spacer arrangement. This avoids the magnets tipping over or getting stuck due to angular deviations during feeding, improving the linearity and stability of the feeding action.

[0010] As an improvement, the storage rack includes a base perpendicular to one side of the lifting seat and a baffle protruding upwards from one side of the base. The baffle is parallel to one side of the lifting seat, and a placement groove for placing the magnetic spacer assembly is formed between the baffle and the base. The front end of the placement groove has a push port for the top block to enter, and the rear end of the placement groove has a discharge port for connecting to the front opening of the guide chute. With this structure, the placement groove formed by the baffle and the base provides lateral restraint for the magnetic spacer assembly, preventing lateral deviation of the material during pushing. The alignment design of the push port and the discharge port ensures that the pushing force of the top block acts directly on the front end of the magnetic spacer assembly, ensuring that the entire column of material enters the guide chute along a straight path and avoiding localized jamming.

[0011] As an improvement, the guide seat includes a first guide plate and a second guide plate arranged in parallel. The first guide plate is fixed to the top of the loading platform, and the second guide plate is horizontally movable on the top of the loading platform via a spacing adjustment mechanism. The spacing adjustment mechanism is used to adjust the spacing between the first and second guide plates. A guide groove is formed between the first and second guide plates. The spacing adjustment mechanism includes a limiting groove extending along the width direction of the guide groove on the second guide plate and a fixing bolt threaded to the loading platform. The fixing bolt is inserted into the limiting groove and fixedly connected to the loading platform at any position within the limiting groove. With this structure, the adjustable-spacing guide plate structure, through the cooperation of the limiting groove and the fixing bolt, allows the guide groove width to adapt to the width requirements of different specifications of magnets and spacers, ensuring that the magnet and spacer arrangement is tightly arranged within the guide groove without shaking. It also simplifies the guide groove width adjustment operation and improves the equipment's versatility.

[0012] As an improvement, a placement seat for single magnets is provided at one end of the distribution trough. The placement seat can be moved up and down within the distribution trough via a lifting cylinder. With this structure, when a magnet is pushed to the placement seat at one end of the distribution trough, the lifting cylinder drives the placement seat to vertically lift the magnet to a preset picking height, causing the magnet to detach from the distribution trough and be exposed at the picking station. This facilitates precise gripping by a robot arm, suction cup, or magnetic suction mechanism. Simultaneously, the lifting cylinder's lifting action is synchronized with the distribution rhythm, and it quickly resets after lifting the magnet, avoiding obstruction of the distribution path for the next magnet. This achieves seamless connection between the distribution, lifting, and picking processes, ensuring the continuity of magnet flow within the distribution trough and the accuracy of picking positioning.

[0013] As an improvement, the material distribution seat includes a first material distribution plate and a second material distribution plate arranged side by side. The first material distribution plate is vertically arranged at the rear end of the second material guide plate. One end of the first material distribution plate is bent forward to form an L-shaped bend. The second material distribution plate is located between the L-shaped bend and the first material guide plate and can be moved back and forth on the loading platform through a second slider rail assembly. A compression spring assembly for driving the second material distribution plate to move closer to the first material distribution plate is provided between the front end of the second material distribution plate and the loading platform. An inclined guide surface is provided on the rear end of the second material distribution plate near the first material guide plate. The inclined guide surface is inclined from the rear end near the L-shaped bend to the front end near the first material guide plate. A material distribution groove is formed between the first material distribution plate, the second material distribution plate, the first material guide plate, and the second material guide plate. The placement seat is located between the first material distribution plate and the second material distribution plate. After applying this structure, the compression spring assembly drives the second distribution plate to elastically press against the first distribution plate, so that the magnet entering the distribution groove is stably clamped between the gripper structure formed by the first and second distribution plates, eliminating the back-and-forth swaying of the magnet on the placement seat and ensuring the positional accuracy when the lifting cylinder lifts the magnet. The inclined guide surface and the bidirectional push block work together to guide the magnet to slide into the gripper area along the inclined surface, avoiding hard collision between the edge of the magnet and the distribution plate. The closed end of the distribution groove forms a magnet limiting structure through the L-shaped bend, so that the magnet is accurately placed on the placement seat to wait for lifting, while the open end allows the partition to slide directly out of the distribution groove, realizing the separation of the magnet and the partition. The gripper structure and the vertical lifting of the placement seat cooperate to ensure the stability of the magnet clamping and provide a non-interference picking space for the robot, suction cup or magnetic attraction mechanism, significantly improving the material distribution accuracy and picking reliability.

[0014] Specifically, the magnet insertion and gluing mechanism includes a worktable, a turntable mechanism rotatably mounted on the worktable, gluing equipment distributed around the turntable mechanism, and at least one magnet insertion mechanism. The turntable mechanism is circumferentially provided with multiple clamps for fixing the motor rotor core. The turntable mechanism drives the clamps to pass through the gluing equipment and the magnet insertion mechanism in sequence. The magnet supply mechanism is set corresponding to the magnet insertion mechanism. The loading platform of the magnet supply mechanism is fixed to the top of the worktable and located around the turntable mechanism. After applying this structure, the turntable mechanism carries the motor rotor core through the rotating drive fixture, passing sequentially through the glue application station and the magnet insertion station, realizing the cyclical operation of the glue application and magnet insertion processes. The magnet supply mechanism and the magnet insertion mechanism are positioned in a corresponding manner, so that the precisely positioned magnets after material distribution are directly exposed within the picking range of the magnet insertion mechanism. The magnet insertion mechanism actively picks up the magnets and performs the insertion action through a robotic arm, suction cup, or magnetic attraction. This avoids the positioning error caused by the secondary transfer of magnets between stations, and through the synchronous control of the turntable mechanism and the magnet distribution cycle, it realizes the collaborative operation of multiple processes such as glue application, material distribution, and magnet insertion, significantly shortening the production cycle and improving the overall automation level.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] like Figures 1 to 4As shown, a motor insert magnet gluing device includes an insert magnet gluing mechanism and a magnet supply mechanism. The magnet supply mechanism includes a loading platform 1, a loading mechanism 2, a guide seat 4 with a guide trough 40, and a distribution seat 5 with a distribution trough 50, all mounted on the loading platform 1. The distribution trough 50 is vertically connected to the rear end of the guide trough 40. A pushing mechanism 3 is provided at the front end of the guide trough 40. The loading mechanism 2 is horizontally or vertically mounted on the loading platform 1 and has multiple rows of storage racks 6. Each row of storage racks 6 has a magnet spacer arrangement consisting of alternating magnets and spacers. The loading mechanism 2 is used to move the storage racks 6 to the front opening of the guide trough 40, and the pushing mechanism 3 is used to... The magnetic steel spacer arrangement is driven to move backward from the storage rack 6 along the guide groove 40 into the distribution groove 50. Inside the distribution groove 50, a bidirectional pusher 502 is provided for bidirectional movement via a bidirectional drive mechanism 501. The bidirectional drive mechanism 501 can be a common cylinder, oil cylinder, push cylinder, or other drive mechanism with linear drive function. When the bidirectional pusher 502 moves toward one end of the distribution groove 50, it drives the individual magnetic steel spacer in the magnetic steel spacer arrangement to move toward one end of the distribution groove 50. When the bidirectional pusher 502 moves toward the other end of the distribution groove 50, it drives the individual spacer in the magnetic steel spacer arrangement to move toward the other end of the distribution groove 50.

[0025] In this embodiment, a magnetic steel separator arrangement group, consisting of alternating magnets and separators, physically isolates adjacent magnets during the conveying process in the guide trough 40, effectively weakening the direct magnetic attraction between magnets. This significantly reduces the thrust required for subsequent material separation processes, allowing the use of a general-purpose low-thrust cylinder to complete the separation action. This reduces equipment costs and avoids the risk of magnet breakage caused by strong thrust. The bidirectional push block 502 in the material separation trough 50, in conjunction with the bidirectional drive mechanism 501, enables the magnets and separators to separate synchronously in opposite directions within the same material separation cycle. Combined with the vertical connection structure between the material separation trough 50 and the guide trough 40, precise separation of magnets and separators is achieved, improving material separation efficiency while ensuring the continuity of the material separation action. The combined design of the multi-row storage rack 6 and the movable feeding mechanism 2 enables continuous feeding of the magnetic steel separator arrangement group, reducing equipment downtime for material changes and providing a stable and reliable material supply foundation for the efficient coordination of automated magnet insertion and gluing processes.

[0026] Furthermore, the width of the distribution trough 50 is greater than the maximum of the thickness of a single magnet and the thickness of a single partition, but less than the sum of their thicknesses. The bidirectional pusher 502 is positioned near the rear of the distribution trough 50, and its width is less than or equal to the minimum of the thickness of a single magnet and the thickness of a single partition. With this structure, the width limitation of the distribution trough 50, combined with the dimensional constraints of the bidirectional pusher 502, ensures that the magnet and partition can only move in a single-layer alternating arrangement within the distribution trough 50. The width limitation of the bidirectional pusher 502 ensures that it can only contact a single magnet or partition simultaneously. The reciprocating motion of the bidirectional pusher 502 achieves precise directional separation of the magnet and partition, avoiding stacking and jamming during the pushing process and reducing the mechanical impact on the material during separation.

[0027] like Figure 5 As shown, the front opening of the guide trough 40 is provided with a front guide port 401 that gradually expands outward from back to front, and the rear opening of the guide trough 40 is provided with a rear guide port 402 that gradually expands outward from front to back. With this structure, the flared guide port structure at both ends of the guide trough 40 allows the front guide port 401 to guide the magnetic steel spacer assembly smoothly into the guide trough 40, while the rear guide port 402 forms a smooth transition at the junction of the guide trough 40 and the distribution trough 50. This allows the separated individual magnets or spacers to move and slide along the extension direction of the distribution trough 50 into the corresponding distribution station, reducing the risk of material stagnation at the intersection of the guide trough 40 and the distribution trough 50. Simultaneously, the outward expansion structure can compensate for minor positional deviations during material conveying, ensuring the alignment of the magnets and spacers before and after separation, and preventing material jamming or distribution failure due to misalignment.

[0028] like Figure 1 and Figure 2As shown, the feeding mechanism 2 includes a vertical frame 21 fixed to the top of the feeding platform 1, a lifting seat 22 slidably mounted on the frame 21 via a first slider rail assembly 81, and a screw motor assembly 23 fixed to the frame 21 for driving the lifting seat 22 to move up and down. The frame 21 is distributed front and rear at the front end of the guide trough 40, and multiple rows of storage racks 6 are fixed vertically at intervals on one side plate of the lifting seat 22. The screw motor assembly 23 is a combination structure of motor and screw in the prior art. Typically, the motor is fixed to the top of the frame 21, and the screw is distributed vertically on the frame 21. The upper end of the screw is fixed to the rotating output end of the motor, and the lower end of the screw is rotatably mounted on the frame 21 via a bearing. A threaded connecting seat is threaded onto the screw, and the threaded connecting seat is fixedly connected to the lifting seat 22. The forward and reverse rotation of the motor drives the threaded connecting seat to rise and fall on the screw, thereby driving the lifting seat 22 to rise and fall synchronously. After applying this structure, the lifting seat 22 driven by the screw motor, together with the storage racks 6 arranged in multiple vertical rows, can achieve precise positioning of the magnetic steel partitions of different heights layer by layer. Through the lifting motion, the empty storage rack 6 is moved out of the work station and the full-load storage rack 6 is sent into the front end of the guide chute 40, ensuring continuous material supply and significantly reducing downtime for material change.

[0029] like Figure 2 As shown, the pushing mechanism 3 includes a linear drive module 31 fixedly mounted on the loading platform 1, and a top block 32 fixed on the movable block of the linear drive module 31. The storage rack 6 is arranged parallel to the front of the linear drive module 31, and the guide chute 40 is arranged parallel to the rear of the linear drive module 31. The linear drive module 31 can also be replaced by a common cylinder, hydraulic cylinder, push cylinder, or other drive mechanism with the same linear drive function. With this structure, the linear motion path of the linear drive module 31 and the top block 32 is arranged parallel to the storage rack 6 and the guide chute 40, ensuring that the pushing direction of the top block 32 is consistent with the moving direction of the magnetic steel spacer arrangement group, avoiding the magnets from tipping over or getting stuck due to angular deviation during the pushing process, and improving the linearity and stability of the pushing action.

[0030] like Figure 2As shown, the storage rack 6 includes a base 61 perpendicular to one side of the lifting seat 22 and a retaining edge 62 protruding upward from one side of the base 61. The retaining edge 62 is parallel to one side of the lifting seat 22. A placement groove 63 for placing the magnetic steel spacer assembly is formed between the retaining edge 62 and the base 61. The front end of the placement groove 63 has a push port 631 for the top block 32 to enter, and the rear end of the placement groove 63 has a discharge port 632 for connecting to the front opening of the guide groove 40. Adjacent magnetic steel pieces attract each other under the action of magnetic attraction. Thus, the combination of multiple magnetic steel pieces and multiple spacers forms an integral structure. Therefore, as an integral structure, the magnetic steel pieces and spacers will not fall out from the openings at both ends of the placement groove 63. After applying this structure, the placement groove 63 formed by the side guard 62 and the base 61 provides lateral restraint to the magnetic steel spacer arrangement group, preventing the material from shifting laterally during the pushing process. The alignment design of the push port 631 and the discharge port 632 ensures that the pushing force of the top block 32 acts directly on the front end of the magnetic steel spacer arrangement group, ensuring that the entire column of material enters the guide groove 40 along a straight path and avoiding local jamming.

[0031] like Figure 3 As shown, the guide seat 4 includes a first guide plate 41 and a second guide plate 42 arranged in parallel. The first guide plate 41 is fixed to the top of the loading platform 1. The second guide plate 42 is horizontally movable on the top of the loading platform 1 through a spacing adjustment mechanism 7. The spacing adjustment mechanism 7 is used to adjust the spacing between the first guide plate 41 and the second guide plate 42. The guide groove 40 is formed between the first guide plate 41 and the second guide plate 42. The spacing adjustment mechanism 7 includes a limiting groove 71 extending along the width direction of the guide groove 40 and arranged on the second guide plate 42, and a fixing bolt 72 threadedly connected to the loading platform 1. The fixing bolt 72 is inserted into the limiting groove 71 and fixedly connected to the loading platform 1 at any position of the limiting groove 71. After applying this structure, the adjustable spacing guide plate structure, through the cooperation of the limiting groove 71 and the fixing bolt 72, enables the width of the guide groove 40 to adapt to the width requirements of different specifications of magnets and partitions, ensuring that the magnet and partition arrangement group is tightly arranged in the guide groove 40 without shaking, while simplifying the width adjustment operation of the guide groove 40 and improving the versatility of the equipment.

[0032] like Figure 3 and Figure 5As shown, one end of the material distribution trough 50 is provided with a placement seat 503 for placing single magnets. The placement seat 503 can be moved up and down within the material distribution trough 50 via a lifting cylinder 504. With this structure, when a magnet is pushed to the placement seat 503 at one end of the material distribution trough 50, the lifting cylinder 504 drives the placement seat 503 to vertically lift the magnet to a preset picking height, causing the magnet to detach from the material distribution trough 50 and expose it to the picking position, facilitating precise gripping by a subsequent robotic arm, suction cup, or magnetic suction mechanism. Simultaneously, the lifting action of the lifting cylinder 504 is synchronized with the material distribution rhythm, quickly resetting after lifting the magnet to avoid obstructing the material distribution path of the next magnet. This achieves seamless connection between the material distribution, lifting, and picking processes, ensuring the continuity of magnet flow within the material distribution trough 50 and the accuracy of picking positioning.

[0033] like Figure 3 and Figure 5As shown, the material distribution seat 5 includes a first material distribution plate 51 and a second material distribution plate 52 arranged side by side. The first material distribution plate 51 is vertically disposed at the rear end of the second guide plate 42. One end of the first material distribution plate 51 is bent forward to form an L-shaped bend 510. The second material distribution plate 52 is located between the L-shaped bend 510 and the first guide plate 41 and is movable back and forth on the loading platform 1 via the second slider rail assembly 82. A drive mechanism for the second material distribution plate 52 is provided between the front end of the second material distribution plate 52 and the loading platform 1. 52. The compression spring assembly 83 moves closer to the first distribution plate 51. The rear end of the second distribution plate 52 is provided with an inclined guide surface 520 near the first guide plate 41. The inclined guide surface 520 is inclined from the rear end near the L-shaped bend 510 to the front end near the first guide plate 41. The distribution groove 50 is formed between the first distribution plate 51, the second distribution plate 52, the first guide plate 41, and the second guide plate 42. The placement seat 503 is located between the first distribution plate 51 and the second distribution plate 52. The compression spring assembly 83 is a conventional structure, including a spring, a guide rod, and a fixing block. The fixing block is fixed to the loading platform 1 on the front side of the second distribution plate 52. The guide rod is distributed front and rear and its front end is fixed to the fixing block. The spring is sleeved on the guide rod. The front end of the second distribution plate 52 has a guide hole. The rear end of the guide rod is inserted into the guide hole. The second distribution plate 52 compresses the spring forward. After applying this structure, the compression spring assembly 83 drives the second distribution plate 52 to elastically press against the first distribution plate 51, so that the magnet entering the distribution groove 50 is stably clamped between the gripper structure formed by the first distribution plate 51 and the second distribution plate 52, eliminating the back-and-forth swaying of the magnet on the placement seat 503 and ensuring the positional accuracy of the lifting cylinder 504 when lifting the magnet; the inclined guide surface 520 and the bidirectional push block 502 work together to guide the magnet to slide into the gripper area along the inclined surface, avoiding magnetic... The steel edge makes a hard collision with the material distribution plate; the closed end of the material distribution groove 50 forms a magnetic steel limiting structure through the L-shaped bending part 510, so that the magnetic steel is accurately placed on the placement seat 503 to wait for lifting, while the open end allows the partition to slide directly out of the material distribution groove 50, realizing the separation of the magnetic steel and the partition; the gripper structure cooperates with the vertical lifting of the placement seat 503 to ensure the stability of magnetic steel clamping, and also provides a non-interference material picking space for the robot, suction cup or magnetic suction mechanism, significantly improving the material distribution accuracy and material picking reliability.

[0034] like Figure 6As shown, the magnet insertion and gluing mechanism includes a worktable 9, a turntable mechanism 91 rotatably mounted on the worktable 9, gluing equipment 92 distributed around the turntable mechanism 91, and at least one magnet insertion mechanism 93. The turntable mechanism 91 is circumferentially provided with multiple clamps 90 for fixing the motor rotor core. The turntable mechanism 91 drives the clamps 90 to pass through the gluing equipment 92 and the magnet insertion mechanism 93 in sequence. The magnet supply mechanism is set corresponding to the magnet insertion mechanism 93. The loading platform 1 of the magnet supply mechanism is fixed to the top of the worktable 9 and located around the turntable mechanism 91. After applying this structure, the turntable mechanism 91 carries the motor rotor core through the rotating drive fixture 90, passing sequentially through the glue application station and the magnet insertion station, realizing the cyclical operation of the glue application and magnet insertion processes. The magnet supply mechanism and the magnet insertion mechanism 93 are arranged in a corresponding manner, so that the magnets that are accurately positioned after material distribution are directly exposed within the picking range of the magnet insertion mechanism 93. The magnet insertion mechanism 93 actively picks up the magnets and performs the insertion action through a robotic arm, suction cup, or magnetic attraction. This avoids the positioning error caused by the secondary transfer of magnets between stations. Furthermore, through the synchronous control of the turntable mechanism 91 and the magnet distribution cycle, the collaborative operation of multiple processes such as glue application, material distribution, and magnet insertion is realized, significantly shortening the production cycle and improving the overall automation level.
