Description

Technical Field

[0001] This invention relates to the field of rotor manufacturing equipment technology, and in particular to a vertical magnet attaching mechanism. Background Technology

[0002] In the field of motor manufacturing, especially in the production of permanent magnet motors, the precise and efficient mounting of magnets onto the outer surface of the rotor is a critical process. Traditional magnet mounting processes are mostly completed manually or with semi-automated equipment, resulting in low efficiency, poor consistency, and a tendency for missed or misaligned magnets. Furthermore, due to the strong magnetism of the magnets themselves, multiple magnets are prone to sticking together and difficult separation during automated feeding and mounting processes, further increasing the difficulty of process control. For example, in the feeding stage, the strong magnetism of the magnets easily attracts each other, often leading to multiple magnets sticking together, jamming, or poor separation, causing mounting failures or equipment downtime. In the mounting stage, common robotic arms or suction cup structures, when removing after mounting, are prone to picking up already mounted magnets due to magnetic attraction, damaging the mounting effect. Therefore, existing equipment often lacks efficient material changing and pressure holding mechanisms, making it difficult to achieve continuous and rapid operation on multiple magnet mounting surfaces of the rotor. Summary of the Invention

[0003] In view of this, the present invention provides a vertical magnet attaching mechanism to solve the above-mentioned technical problems.

[0004] A vertical magnet attaching mechanism includes a rotary clamping mechanism, at least one storage mechanism, and at least one attaching mechanism. The rotary clamping mechanism clamps a rotor and drives it to rotate. The attaching mechanism includes a frame, a third linear drive device mounted on the frame, a push block mounted on the third linear drive device, a base plate mounted on the frame, two guide blocks spaced apart on the frame, a limiting block mounted on the frame, a fourth linear drive device mounted on the frame, and two attaching assemblies mounted on the frame. The third linear drive device drives the push block to reciprocate and pushes multiple magnets in the storage mechanism toward the guide blocks. The limiting block has a vertically arranged limiting groove, the two ends of which pass through the limiting block. The size of the limiting groove is the same as the size of one magnet. The limiting block has a through hole on the side facing the guide block, and the through hole connects to the two guide blocks. The gap between the guide blocks and the limiting groove are connected. The output end of the fourth linear drive device is provided with a pressing rod. The pressing rod is movably inserted into the limiting groove. The output direction of the fourth linear drive device is parallel to the extension direction of the limiting groove. The pressing rod presses down to push the first magnet, separating the first magnet and continuing to push it towards the two-section mounting assembly. The two-section mounting assembly includes a fifth linear drive device on the frame, a mounting block on the fifth linear drive device, a sixth linear drive device on the mounting block, and a metal block on the output end of the sixth linear drive device. The mounting block has an arc-shaped mounting surface facing the rotary clamping mechanism. The arc of the mounting surface is the same as the arc of the magnet. The metal block attracts the magnet. The metal block is arc-shaped facing the rotary clamping mechanism and has the same arc as the mounting surface.

[0005] Furthermore, the rotary clamping mechanism includes a frame, a first linear drive device disposed on the frame, a fixing block disposed on the first linear drive device, a rotary drive device, a clamping device disposed on the rotary drive device, and a plurality of clamping blocks disposed on the clamping device.

[0006] Furthermore, the first linear drive device is used to drive the fixed block to move vertically, the fixed block is used to rotatably insert one end of the rotor, the rotary drive device is located above the first linear drive device, the output end of the rotary drive device is provided with the clamping device, and the three output ends of the clamping device are respectively provided with the clamping blocks, so as to drive the three clamping blocks to move closer to each other to clamp the other end of the rotor.

[0007] Furthermore, the storage mechanism includes a second linear drive device, a hopper disposed on the second linear drive device, and a plurality of storage troughs disposed on the hopper.

[0008] Furthermore, the storage trough is located between the push block and the guide block, and the arrangement direction of the plurality of storage troughs is parallel to the moving direction of the output end of the second linear drive device. The end of the storage trough away from the mounting mechanism is used for feeding, and the top of the storage trough is connected to the top of the hopper.

[0009] Furthermore, the guide block is located between the limiting block and the storage tank, the gap between the two guide blocks is used to accommodate the magnet, the distance between the two guide blocks is greater than or equal to the width of the magnet, one end of the two guide blocks is aligned and connected to the storage tank, and the other end abuts against the limiting block, and the bottom plate is located below the guide block.

[0010] Furthermore, the through hole and the guide block are chamfered on the side facing the magnet conveying direction.

[0011] Furthermore, during mounting, the sixth linear drive device moves the metal block and aligns it with the mounting surface on the side of the rotary clamping mechanism. The pressing rod pushes a magnet out of the limiting groove and it is attracted by the metal block. The fifth linear drive device moves the mounting block and the metal block synchronously toward the rotary clamping mechanism, so that the magnet is attached to the rotor. The metal block and the mounting surface simultaneously press the magnet tightly against the rotor. The sixth linear drive device independently controls the metal block to retract and separate from the magnet.

[0012] Compared with existing technologies, the vertical magnet-attaching mechanism provided by this invention significantly improves the efficiency, accuracy, and reliability of magnet mounting through the coordinated cooperation of its components. The rotary clamping mechanism achieves vertical positioning of the rotor via the first linear drive device, and drives the rotor held by the clamping device and the clamping blocks to rotate using the rotary drive device. This allows multiple surfaces of the rotor to be mounted to be aligned sequentially with the mounting stations, enabling continuous mounting at multiple stations and reducing repetitive positioning time. The material storage mechanism drives the material hopper to move via the second linear drive device, allowing multiple material storage tanks to be supplied alternately or continuously, effectively reducing downtime for material changes and ensuring production continuity. The mounting mechanism uses the third linear drive device to push the pusher block to transport the magnet from the material storage tank through the guide block and the base plate to the limiting block. The cooperation of the limiting groove and the through hole achieves precise positioning of a single magnet. Then, the fourth linear drive device drives the pressing rod to separate the magnet and push it to the two mounting components, effectively avoiding the risk of mounting multiple magnets simultaneously. The two mounting components are driven by the fifth linear drive device to move the mounting block, the sixth linear drive device, and the metal block in a coordinated manner. First, the magnetism of the metal block attracts the magnet, and together with the mounting surface, the magnet is pressed onto the surface of the adhesive rotor. Then, the metal block is driven by the sixth linear drive device to retract first, while the non-magnetic mounting surface continues to be pressed. This ensures accurate mounting positioning and adhesive strength, and avoids the problem of the already attached magnet being lifted when the mechanism resets. The overall mechanism is reasonably designed and the operation is smooth, which greatly improves the mounting quality and production efficiency. Attached Figure Description

Detailed Implementation

[0024] The following provides a more detailed description of specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the scope of protection of the present invention.

[0025] like Figures 1 to 10 The diagram shown is a structural schematic of the vertical magnet-applying mechanism provided by the present invention. The vertical magnet-applying mechanism includes a rotating clamping mechanism 10, at least one material storage mechanism 20, and at least one applicating mechanism 30. It is conceivable that the vertical magnet-applying mechanism also includes other functional components, such as mounting components, connecting components, etc., which are technologies well known to those skilled in the art and will not be described in detail here.

[0026] It should be noted that the vertical magnet attaching mechanism is used to complete the process of attaching magnets to the rotor. The magnets are magnetic. The rotor and the magnets should be existing technology, and will not be described in detail here.

[0027] The rotary clamping mechanism 10 includes a frame 11, a first linear drive device 12 disposed on the frame 11, a fixing block 13 disposed on the first linear drive device 12, a rotary drive device 14, a clamping device 15 disposed on the rotary drive device 14, and a plurality of clamping blocks 16 disposed on the clamping device 15.

[0028] The frame 11 is used to support the first linear drive device 12 and the material storage mechanism 20. Therefore, the frame 11 is equipped with various functional structures, such as screws, bolts, clamps, etc., to complete the installation and assembly of the above-mentioned functional modules. It can be set according to actual needs, and will not be described in detail here. The first linear drive device 12 is used to drive the fixed block 13 to move vertically. The fixed block 13 is used to rotate and insert one end of the rotor. The rotary drive device 14 is located above the first linear drive device 12 and connected to the external mounting frame. The output end of the rotary drive device 14 is provided with the clamping device 15, thereby driving the clamping device 15 and the rotor clamped by the clamping device 15 to rotate, so as to turn different sides of the rotor towards the mounting mechanism 30 for mounting. The clamping device 15 is a three-jaw cylinder. The three output ends of the clamping device 15 are respectively provided with clamping blocks 16, thereby driving the three clamping blocks 16 to move closer to each other to clamp the other end of the rotor.

[0029] The storage mechanism 20 includes a second linear drive device 21, a hopper 22 disposed on the second linear drive device 21, and a plurality of storage troughs 23 disposed on the hopper 22.

[0030] The second linear drive device 21 drives the hopper 22 to move linearly back and forth. The arrangement direction of the multiple storage slots 23 is parallel to the movement direction of the output end of the second linear drive device 21, thereby aligning different storage slots 23 with the mounting mechanism 30. When the magnets in one storage slot 23 are used up, the second linear drive device 21 can quickly switch, realizing continuous or alternating material supply to different slots and reducing downtime for material changes. The storage slots 23 pass through the hopper 22, thus connecting the two ends of the storage slots 23. The end of the storage slot 23 away from the mounting mechanism 30 is used for manual or robotic loading. Because the magnets are magnetic, multiple magnets are pre-stored in a straight line, attracting each other. Then, the manual or robotic arm puts multiple magnets into the storage slot 23 from the end away from the mounting mechanism 30. The top of the storage tank 23 is connected to the top of the hopper 22, which is used to avoid the pushing action of the mounting mechanism 30. A detailed explanation will be given below in conjunction with the mounting mechanism 30.

[0031] The mounting mechanism 30 includes a frame 31, a third linear drive device 32 mounted on the frame 31, a pusher block 33 mounted on the third linear drive device 32, a base plate 34 mounted on the frame 31, two guide blocks 35 spaced apart on the frame 31, a limiting block 36 mounted on the frame 31, a fourth linear drive device 37 mounted on the frame 31, and a two-segment mounting assembly 38 mounted on the frame 31.

[0032] The frame 31 is a hollow frame formed by multiple plates and is used to support the above-mentioned components. Therefore, the frame 11 is provided with a variety of functional structures, such as screws, bolts, etc., to complete the installation and assembly of the above-mentioned functional modules. It can be set according to actual needs, and will not be described in detail here.

[0033] The third linear drive device 32 is used to drive the push block 33 to move back and forth. The storage tank 23 is located between the push block 33 and the guide block 35, so that the push block 33 can push multiple magnets in the storage tank 23 to move toward the guide block 35. The opening at the top of the storage tank 23 can avoid the push block 33 from moving in the storage tank 23, thereby realizing the conveying of magnets.

[0034] The guide block 35 is located between the limiting block 36 and the storage trough 23. The gap between the two guide blocks 35 is used to accommodate the magnet. The distance between the two guide blocks 35 is greater than or equal to the width of the magnet, thereby ensuring stable magnet conveying. One end of each guide block 35 is aligned and connected to the storage trough 23, and the other end abuts against the limiting block 36. The base plate 34 is located below the guide blocks 35, thereby supporting the magnet that has detached from the storage trough 23. When the magnet in the storage trough 23 leaves the storage trough 23 under the push of the push block 33, it will enter between the two guide blocks 35 and the base plate 34 and continue to be conveyed towards the limiting block 36 under the push of the push block 33.

[0035] The limiting block 36 is vertically provided with a limiting groove 361, the two ends of the limiting groove 361 are through the limiting block 36, and the size of the limiting groove 361 is the same as the size of one of the magnets, so that the limiting groove 361 can only accommodate one magnet.

[0036] The limiting block 36 has a through hole 362 on the side facing the guide block 35. The through hole 362 communicates with the gap between the two guide blocks 35 and the limiting groove 361, allowing the magnet to enter the limiting groove 361 through the through hole 362. To better transport the magnet, the through hole 362 and the guide block 35 are chamfered on the side facing the magnet transport direction. The chamfer acts as a guide, thus preventing the magnet from getting stuck due to uneven height caused by installation errors.

[0037] The output end of the fourth linear drive device 37 is provided with a pressing rod 371, which is movably inserted into the limiting groove 361. The output direction of the fourth linear drive device 37 is parallel to the extension direction of the limiting groove 361, thereby driving the pressing rod 371 to move within the limiting groove 361. When multiple mutually attracted magnets continue to be dispensed, only the first magnet is located in the limiting groove 361. The pressing rod 371 presses down and pushes the first magnet, separating it individually and continuing to push it towards the two-section mounting assembly 38. After the pressing rod 371 resets, the multiple mutually attracted magnets move again under the action of the push block 33, allowing the second magnet to enter the limiting groove 361. This ensures that only one magnet can be accommodated and separated at a time, effectively avoiding mounting failures caused by multiple magnets being pushed simultaneously and ensuring the accuracy of each mounting.

[0038] The two-segment mounting assembly 38 includes a fifth linear drive device 381 mounted on the frame 31, a mounting block 382 mounted on the fifth linear drive device 381, a sixth linear drive device 383 mounted on the mounting block 382, ​​and a metal block 384 mounted at the output end of the sixth linear drive device 383.

[0039] The two mounting components 38 are located in the output direction of the limiting groove 361, so that the magnet pushed out from the limiting groove 361 will enter the two mounting components 38. The fifth linear drive device 381 is used to drive the mounting block 382 and the sixth linear drive device 383 to move closer to or away from the rotary clamping mechanism 10. The mounting block 382 has an arc-shaped mounting surface 385 on the side facing the rotary clamping mechanism 10, and the curvature of the mounting surface 385 is the same as the curvature of the magnet. The sixth linear drive device 383 is used to drive the metal block 384 to move closer to or away from the rotary clamping mechanism 10. The metal block 384 is made of metal, so it can attract the magnetic magnet, so that the magnet pushed out from the limiting groove 361 will be attracted by the metal block 384. The metal block 384 is arc-shaped towards the rotating clamping mechanism 10, and its arc is the same as that of the mounting surface 385. The sixth linear drive device moves the metal block 384 so that it faces the rotating clamping mechanism 10 and is flush with the mounting surface 385, thereby ensuring that the magnet can be stably attached to the metal block 384 and the mounting surface 385. During mounting, the sixth linear drive device first moves the metal block 384 so that it faces the rotating clamping mechanism 10 and is flush with the mounting surface 385. Then, the pressing rod 371 pushes a magnet out of the limiting groove 361 and it is attracted by the metal block 384. The fifth linear drive device 381 moves the mounting block 382 and the metal block 384 synchronously towards the rotating clamping mechanism 10, so that the magnet is attached to the rotor, which has been pre-applied with adhesive. At this point, the metal block 384 and the mounting surface 385 simultaneously press the magnet tightly against the rotor. Then, the sixth linear drive device 383 independently controls the metal block 384 to retract, thus relying solely on the mounting surface 385 to press the magnet tightly against the rotor. Finally, the mounting block 382 resets and separates from the magnet. Because the mounting block 382 is made of non-metallic material, the mounting surface 385 can be easily separated from the magnet when the fifth linear drive device 381 resets. After mounting is complete, the rotating clamping mechanism 10 rotates the rotor so that the side without the magnet faces the two mounting assemblies 38 and mounts the magnet again following the above steps. The two mounting components 38 first attract the magnet through the metal block 384 and send it together with the mounting surface 385 to the rotor adhesive surface. Then, the sixth linear drive device 383 drives the metal block 384 to retreat independently. At this time, the non-magnetic mounting surface 385 still firmly presses the magnet to maintain pressure. By utilizing the magnetic attraction of the magnet to the metal block 384 and the non-magnetic easy separation of the non-metallic mounting block 382, ​​the initial positioning and effective pressing during mounting are guaranteed, and the risk of the attached magnet being lifted during the mechanism reset is avoided, which greatly improves the mounting success rate and reliability.

[0040] Compared with existing technologies, the vertical magnet-attaching mechanism provided by this invention significantly improves the efficiency, accuracy, and reliability of magnet mounting through the coordinated operation of its components. The rotary clamping mechanism 10 achieves vertical positioning of the rotor via the first linear drive device 12, and, with the help of the rotary drive device 14, drives the rotor held by the clamping device 15 and the clamping blocks 16 to rotate, allowing multiple surfaces of the rotor to be mounted to be aligned sequentially with the mounting stations, achieving continuous mounting at multiple stations and reducing repetitive positioning time. The material storage mechanism 20 drives the material bin 22 to move via the second linear drive device 21, enabling multiple material storage tanks 23 to supply material alternately or continuously, effectively reducing downtime for material changes and ensuring production continuity. The mounting mechanism 30 uses the third linear drive device 32 to push the push block 33 to transport the magnet from the storage tank 23 through the guide block 35 and the base plate 34 to the limiting block 36. The cooperation of the limiting groove 361 and the through hole 362 realizes the precise positioning of a single magnet. Then, the fourth linear drive device 37 drives the pressing rod 371 to separate the magnet and push it to the two mounting components 38, effectively avoiding the risk of mounting multiple magnets at the same time. The two mounting components 38 are driven by the fifth linear drive device 381 to move the mounting block 382, ​​the sixth linear drive device 383, and the metal block 384 in a coordinated manner. First, the magnetism of the metal block 384 attracts the magnet, and together with the mounting surface 385, the magnet is pressed onto the surface of the adhesive rotor. Then, the metal block 384 is driven by the sixth linear drive device 383 to retract first, while the non-magnetic mounting surface 385 continues to maintain pressure. This ensures accurate mounting positioning and adhesive strength, and avoids the problem of the already mounted magnet being lifted when the mechanism resets. The overall mechanism design is reasonable and the operation is smooth, which greatly improves the mounting quality and production efficiency.
