Description

Technical Field

[0001] This invention belongs to the field of processing equipment technology, specifically, it relates to a permanent magnet brushless motor stator and rotor processing equipment and method. Background Technology

[0002] Permanent magnet brushless motors are a type of high-efficiency and reliable motor. They use permanent magnets as the rotor and employ an electronic commutator instead of traditional brushes to achieve current commutation, avoiding mechanical wear and electromagnetic interference. The stator is made of laminated silicon steel sheets with embedded multi-phase windings, generating a rotating magnetic field when energized; the rotor is composed of permanent magnets, providing a constant magnetic field. The interaction of the stator and rotor magnetic fields generates torque, driving the rotor to rotate. Due to its brushless design, permanent magnet brushless motors have advantages such as simple structure, reliable operation, high efficiency, and low noise, and are widely used in aerospace, defense, industrial automation, and everyday life. In the actual production process of stators and rotors, tungsten steel sheets are typically processed into stator and rotor laminations through stamping and cutting. These laminations are then sorted and stacked to form the desired components. However, existing sorting devices commonly use a continuously rotating locating post to position and sort the stator laminations. But this process presents a significant problem: when the stator laminations come into contact with the rotating locating post, they are easily thrown off by centrifugal force. Furthermore, they may tilt and become stuck in the middle of the sorting device, which not only affects production efficiency but may also damage the equipment. Based on this, the present invention is proposed. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a permanent magnet brushless motor stator and rotor processing equipment that can overcome the above problems or at least partially solve the above problems.

[0004] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows: a permanent magnet brushless motor stator and rotor processing equipment, including a feeding mechanism, a leveling mechanism, and a stamping mechanism, further including: a feeding slide rail on the stamping mechanism, wherein stator laminations and rotor laminations are separated when passing through the feeding slide rail; a support base is provided below the feeding slide rail, and a support plate is slidably connected to the support base; a stator sorting assembly and a rotor sorting assembly are respectively provided on the support plate, which are used to collect and sort the stator and rotor laminations; a top material rack is provided above the support base, and a stop block is provided above the top material rack, and a sliding clamp is slidably connected to the stop block; when the stator and rotor sorting assemblies descend, the sorted stator and rotor laminations are left on the top material rack; when the stator and rotor sorting assemblies descend, the sliding clamp catches the stator and rotor laminations falling from the feeding slide rail.

[0005] Preferably, the stator straightening assembly includes a first fixed guide post, a first rotating guide post, and a first reciprocating guide post. The first fixed guide post is fixedly connected to the support plate, and the first rotating guide post and the first fixed guide post are both rotatably connected to the support plate. The top of the first rotating guide post is provided with a thread. When the first rotating guide post rotates, the stator laminations are guided down onto the first reciprocating guide post by the thread at the top of the first rotating guide post.

[0006] Furthermore, a first external gear ring is provided at the bottom of the first rotating guide column, and a drive gear is rotatably connected inside the support plate, the drive gear meshing with the first external gear ring.

[0007] Furthermore, a second servo motor is provided on the lower end surface of the support plate, and the output end of the second servo motor is connected to the drive gear. A first eccentric block is provided on the upper end surface of the drive gear, and a limiting protrusion is provided on the lower end surface of the first reciprocating guide column. A sliding block is slidably connected inside the support plate. The limiting protrusion and the first eccentric block are both slidably connected in the sliding block. When the drive gear rotates, the sliding block and the first reciprocating guide column reciprocate. The stator plate above the first reciprocating guide column slides under the action of inertia and aligns with the limiting block on the first reciprocating guide column before falling.

[0008] Furthermore, the rotor straightening assembly includes a second fixed guide post, a second rotating guide post, and a second reciprocating guide post. The second fixed guide post is fixedly connected to the support plate, and the second rotating guide post and the second reciprocating guide post are rotatably connected to the support plate.

[0009] Furthermore, a transmission gear and a guide gear are rotatably connected to the support plate, the transmission gear meshing with the first external gear ring and the guide gear respectively, the bottom end of the second rotating guide post is provided with a second external gear ring, and the top of the second rotating guide post is provided with a thread; the guide gear meshes with the second external gear ring, the second reciprocating guide post is provided with a sliding groove, the guide gear is provided with a second eccentric block, the second eccentric block is slidably connected in the sliding groove, when the guide gear rotates, the second reciprocating guide post performs reciprocating motion, and the rotation of the second rotating guide post guides the rotor blades to fall.

[0010] Preferably, the feeding slide rail has an upper sliding surface and a lower sliding surface, and a dropping hole is provided on the upper sliding surface. When the stator lamination and rotor lamination slide across the upper sliding surface, the rotor lamination with a smaller area falls onto the lower sliding surface through the dropping hole.

[0011] Preferably, the stop block is provided with a first servo motor, the output end of the first servo motor is connected to a bidirectional threaded rod, and the bidirectional threaded rod is connected to the sliding clamp plate by threads.

[0012] Preferably, the support base is provided with a first cylinder, the output end of the first cylinder is connected to the support plate, and the top material frame is provided with a second cylinder, the output end of the second cylinder is connected to a push plate. When the support plate, stator sorting assembly and rotor sorting assembly descend, the top material frame pushes the sorted stator laminations and rotor laminations out of the stator sorting assembly and rotor sorting assembly.

[0013] A method for using a permanent magnet brushless motor stator and rotor processing equipment mainly includes the following steps: S1. The silicon steel sheet is leveled and guided from the feeding mechanism to the stamping mechanism and stamped into stator and rotor laminations. S2. The stator and rotor laminations are conveyed to the unloading slide rail and guided by the unloading slide rail to the stator and rotor sorting assemblies. S3. Start the second servo motor to drive the stator and rotor sorting components to sort the stator and rotor laminations. S4. Drive the support plate, stator sorting assembly and rotor sorting assembly to descend, and push the sorted stator and rotor laminations out of the stator sorting assembly and rotor sorting assembly and leave them on the top material rack; S5. Push the push plate to push out the sorted stator and rotor laminations, and reset the stator sorting assembly and rotor sorting assembly to continue sorting the rotor and stator laminations.

[0014] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: This invention, by setting up a sliding track, a stator finishing component, and a rotor finishing component, can automatically separate and finish the stamped stator and rotor laminations, realizing a fully automated process from stamping to finishing, and significantly improving production efficiency.

[0015] The present invention provides threads on the top of the first and second rotating guide posts, thereby enabling the stator and rotor laminations to be guided down to the top of the first and second reciprocating guide posts by rapid rotation, thus preventing the stator and rotor laminations from getting stuck on the fixed guide posts and being unable to fall.

[0016] The present invention provides guide ramps at the top of the first fixed guide post and the second fixed guide post, thereby guiding the stator laminations and rotor laminations to slide onto the first rotating guide post and the second rotating guide post, thus preventing the stator laminations and rotor laminations from falling directly onto the rotating guide post and being flung away.

[0017] This invention controls the first and second reciprocating guide columns to reciprocate at small angles, thereby achieving relative displacement between the first and second reciprocating guide columns and the stator and rotor laminations through inertia. This allows the stator and rotor laminations to be aligned and fall, avoiding the problem of stator or rotor laminations failing to fall or having poor alignment and falling efficiency due to the rotation of the guide columns, thus improving the alignment efficiency.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0021] Example 1: Refer to Figures 1-10 A permanent magnet brushless motor stator and rotor processing equipment includes a feeding mechanism 1, a leveling mechanism 2, and a stamping mechanism 3. It further includes: a feeding slide rail 4 on the stamping mechanism 3, where stator and rotor laminations are separated as they pass through the feeding slide rail 4; a support base 5 below the feeding slide rail 4, with a support plate 53 slidably connected to the support base 5, and a stator sorting assembly 7 and a rotor sorting assembly 8 respectively on the support plate 53, used to collect and sort the stator and rotor laminations; a top material rack 6 above the support base 5, with a stop block 63 above the top material rack 6, and a sliding clamp 66 slidably connected to the stop block 63; when the stator sorting assembly 7 and the rotor sorting assembly 8 descend, the sorted stator and rotor laminations are left on the top material rack 6; when the stator sorting assembly 7 and the rotor sorting assembly 8 descend, the sliding clamp 66 picks up the stator and rotor laminations falling from the feeding slide rail 4.

[0022] In this invention, silicon steel sheets are attached to the feeding mechanism 1 and unfolded and guided to the leveling mechanism 2 for leveling before being sent to the stamping mechanism 3 for stamping. After stamping, the stator and rotor sheets fall onto the conveyor belt and are transported to the unloading slide rail 4. The unloading slide rail 4 can transport the stator and rotor sheets separately. The stator sorting component 7 and rotor sorting component 8 are respectively provided below and in front of the unloading slide rail 4. The stator and rotor sheets separated in the unloading slide rail 4 fall onto the stator sorting component 7 and rotor sorting component 8 for sorting. Compared with the traditional processing method, this device can simultaneously stack and sort the stator and rotor sheets after stamping, realizing a fully automated process from stamping to sorting. This not only greatly improves production efficiency but also ensures the stability and reliability of product quality. Example 2: Refer to Figures 1-10A permanent magnet brushless motor stator and rotor processing equipment is basically the same as in Embodiment 1, but with a further improvement: the stator straightening assembly 7 includes a first fixed guide post 71, a first rotating guide post 72, and a first reciprocating guide post 73. The first fixed guide post 71 is fixedly connected to the support plate 53. The first rotating guide post 72 and the first fixed guide post 71 are both rotatably connected to the support plate 53. The top of the first rotating guide post 72 is threaded. When the first rotating guide post 72 rotates, the stator plates are guided down onto the first reciprocating guide post 73 by the thread at the top of the first rotating guide post 72. The bottom of the guide post 72 is provided with a first external gear ring 721. A drive gear 741 is rotatably connected inside the support plate 53. The drive gear 741 meshes with the first external gear ring 721. A second servo motor 74 is provided on the lower end face of the support plate 53. The output end of the second servo motor 74 is connected to the drive gear 741. A first eccentric block 7411 is provided on the upper end face of the drive gear 741. A limiting protrusion 731 is provided on the lower end face of the first reciprocating guide post 73. A sliding block 75 is slidably connected inside the support plate 53. The limiting protrusion 731 and the first eccentric block 7411 are both slidably connected to the sliding block. In step 75, when the drive gear 741 rotates, the sliding block 75 reciprocates with the first reciprocating guide post 73. The stator laminations above the first reciprocating guide post 73 slide under inertia and align with the limiting block on the first reciprocating guide post 73 before falling. The rotor sorting assembly 8 includes a second fixed guide post 81, a second rotating guide post 82, and a second reciprocating guide post 83. The second fixed guide post 81 is fixedly connected to the support plate 53, and the second rotating guide post 82 and the second reciprocating guide post 83 are rotatably connected to the support plate 53. A transmission gear 84 and a guide gear are rotatably connected to the support plate 53, respectively. The gear 85 and the transmission gear 84 mesh with the first external gear ring 721 and the guide gear 85 respectively. The bottom end of the second rotating guide post 82 is provided with the second external gear ring 821, and the top of the second rotating guide post 82 is provided with threads. The guide gear 85 meshes with the second external gear ring 821. The second reciprocating guide post 83 is provided with a sliding groove 831, and the guide gear 85 is provided with a second eccentric block 851. The second eccentric block 851 is slidably connected in the sliding groove 831. When the guide gear 85 rotates, the second reciprocating guide post 83 reciprocates, and the second rotating guide post 82 rotates to guide the rotor blades to fall.

[0023] In this invention, the corresponding guide posts in the stator tidying assembly 7 and the rotor tidying assembly 8 have roughly the same function. The first fixed guide post 71 and the second fixed guide post 81 are both fixedly connected to the support plate 53. The top of the first fixed guide post 71 and the second fixed guide post 81 is provided with a guide slope so as to guide the stator laminations and rotor laminations to fit into the first fixed guide post 71 and the second fixed guide post 81. It should be noted that the guide slope should not be set too long, so as to avoid the stator laminations and rotor laminations getting stuck on the guide slope and unable to contact the first rotating guide post 72 and the second rotating guide post 82. like Figure 7 As shown, when the second servo motor 74 drives the drive gear 741 to rotate, it drives the first rotating guide post 72 to rotate, which in turn drives the transmission gear 84 and the guide gear 85 to rotate, which in turn drives the second rotating guide post 82 to rotate. The tops of the first rotating guide post 72 and the second rotating guide post 82 are both provided with threads. When the first rotating guide post 72 and the second rotating guide post 82 rotate rapidly, the speed difference between the stator and rotor plates and the first rotating guide post 72 and the second rotating guide post 82 can guide the stator and rotor plates to fall above the first reciprocating guide post 73 and the second reciprocating guide post 83. This can prevent the stator and rotor plates from getting stuck on the fixed guide post and being unable to fall, and also prevent the stator and rotor plates from falling directly on the rotating guide post and being thrown away. like Figure 6 , Figure 8 and Figure 9 As shown, when the drive gear 741 rotates, it drives the sliding block 75 to reciprocate through the first eccentric block 7411. During this reciprocating motion, the sliding block 75 drives the first reciprocating guide post 73 to reciprocate at a small angle through the limiting protrusion 731. This causes the stator laminations to shift, and the inertia allows the stator laminations to move relative to the first reciprocating guide post 73. This allows the stator laminations to engage with the limiting block protruding from the first reciprocating guide post 73 and fall, thus completing the arrangement of the stator laminations. Meanwhile, when the guide gear 85 rotates... During rotation, the guide gear 85 slides in the sliding groove 831 through the second eccentric block 851, thereby driving the second reciprocating guide post 83 to reciprocate at a small angle. This allows the rotor laminations to engage with the limiting rod on the second reciprocating guide post 83 and fall. By reciprocating at a small angle, the rotor and stator laminations can be prevented from getting stuck at a certain point during the fall by wobbling. Compared with the existing method of engaging and falling by unidirectional rotation, this method avoids the problem of stator or rotor laminations failing to fall or having poor engagement and falling efficiency as they follow the rotation of the guide post, thus improving the efficiency of the sorting process.

[0024] Example 3: Reference Figures 1-10A permanent magnet brushless motor stator and rotor processing equipment is basically the same as in Embodiment 2, but with a further improvement: the unloading slide rail 4 has an upper sliding surface 41 and a lower sliding surface 42. The upper sliding surface 41 has a dropping hole 411. When the stator laminations and rotor laminations slide over the upper sliding surface 41, the rotor laminations with smaller areas fall onto the lower sliding surface 42 through the dropping hole 411. The stop block 63 is equipped with a first servo motor 64. The output end of the first servo motor 64 is connected to a bidirectional threaded rod 65. The bidirectional threaded rod 65 is connected to a sliding clamp 66 through threads. The support base 5 is equipped with a first cylinder 52. The output end of the first cylinder 52 is connected to a support plate 53. The top material rack 6 is equipped with a second cylinder 61. The output end of the second cylinder 61 is connected to a push plate 62. When the support plate 53, the stator sorting assembly 7, and the rotor sorting assembly 8 descend, the top material rack 6 pushes the sorted stator laminations and rotor laminations out of the stator sorting assembly 7 and the rotor sorting assembly 8.

[0025] In this invention, such as Figure 2 and Figure 3 As shown, when the stamped stator laminations and rotor laminations pass through the upper sliding surface 41, the rotor lamination at the center falls from the blanking hole 411 onto the lower sliding surface 42, thereby separating the stator laminations from the rotor laminations. The rotor lamination slides along the lower sliding surface 42 and hits the end of the blanking slide rail 4, then falls onto the rotor sorting assembly 8 directly below. After the stator lamination slides out from the upper sliding surface 41, it hits the stop block 63 and then falls onto the stator sorting assembly 7. The first cylinder 52 can drive the support plate 53, stator sorting assembly 7 and rotor sorting assembly 8 to rise and fall together. After the stator sorting assembly 7 and rotor sorting assembly 8 sort a certain amount of stator and rotor laminations, the top material frame 6 can push the stator and rotor laminations out of the stator and rotor sorting assembly 7 and rotor sorting assembly 8 by driving the stator and rotor sorting assembly 7 and rotor sorting assembly 8 to fall. When the stator and rotor sorting assembly 7 and rotor sorting assembly 8 fall to the point that their upper end face is flush with the top material frame 6, the second cylinder 61 can be activated to push the push plate 62 to push the sorted stator and rotor laminations out of the top material frame 6. A conveying mechanism or a robot can be set on the side of the top material frame 6 to move the stacked and sorted stator and rotor laminations to the extrusion device for stacking and fixing, so as to obtain the completed stator and rotor. like Figure 4 and Figure 10 As shown, the first servo motor 64 drives the bidirectional threaded rod 65 to rotate, thereby driving the sliding clamp 66 to make relative displacement. When the stator sorting assembly 7 and the rotor sorting assembly 8 descend, the sliding clamp 66 moves towards the middle to catch the stator and rotor laminations falling from the unloading slide rail 4. After the stator sorting assembly 7 and the rotor sorting assembly 8 are reset, the sliding clamp 66 slides to both sides so that the caught stator and rotor laminations fall onto the stator sorting assembly 7 and the rotor sorting assembly 8 for further sorting.

[0026] Example 4: Reference Figures 1-10 A method for using a permanent magnet brushless motor stator and rotor processing equipment mainly includes the following steps: S1. The silicon steel sheet is leveled and guided from the feeding mechanism 1 to the stamping mechanism 3 through the leveling mechanism 2 and stamped into stator and rotor sheets. S2. The stator laminations and rotor laminations are conveyed to the unloading slide rail 4 and guided by the unloading slide rail 4 to the stator sorting assembly 7 and the rotor sorting assembly 8. S3. Start the second servo motor 74 to drive the stator sorting assembly 7 and the rotor sorting assembly (8) to sort the stator laminations and rotor laminations; S4. Drive the support plate 53, stator sorting assembly 7 and rotor sorting assembly 8 to descend, and push the sorted stator and rotor laminations out of the stator sorting assembly 7 and rotor sorting assembly 8 and leave them on the top material rack 6. S5. Push the push plate 62 to push out the sorted stator laminations and rotor laminations and squeeze them into one piece. Then reset the stator sorting assembly 7 and rotor sorting assembly 8 to continue sorting the rotor laminations and stator laminations.
