Description

Technical Field

[0001] This invention relates to the field of motor manufacturing equipment technology, and more specifically to an automatic magnet insertion device. Background Technology

[0002] An electric motor typically consists of a rotor and a stator. Common rotor end magnets use an internally inserted iron core structure, in which a magnet made of permanent magnet material is inserted into the rotor core. This serves as the motor's rotating mechanism, interacting with the rotating magnetic field generated by the stator to cause the rotor to rotate and produce the motor's output.

[0003] During the manufacturing process of rotor cores, it is necessary to insert the core into the corresponding positions of the magnets. Previously, this was done manually. To address the efficiency issues of manual operation, robotic arms began to be used to perform the magnet insertion. Common magnet insertion devices, such as those disclosed in publication number CN 117277709 A, are typically complex in structure and bulky, using robotic arms to repeatedly grip and insert the magnets. Such equipment involves too many steps, and an error in any step can cause the entire system to stop. Furthermore, magnets are not limited to a single size; many existing magnet insertion devices are specialized machines, which, given the already bulky structure of the equipment, cannot flexibly adapt to the insertion of magnets of different sizes, further increasing the manufacturing cost of the core. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an automatic magnet insertion device.

[0005] The objective of this invention is achieved through the following technical solution:

[0006] An automatic magnet insertion device includes a conveyor for transporting iron cores and a frame mounted on the conveyor. Each iron core has a set of magnet slots for inserting magnets. A material channel positioning fixture is detachably mounted on the top of the frame. A set of through slots communicating with the magnet slots is vertically arranged within the material channel positioning fixture. A set of magnet feeding mechanisms is arranged around the outer periphery of the frame. Each magnet feeding mechanism is connected to the through slot via a magnet-flowing material channel. A cutting mechanism is located at the top of the material channel to allow the magnets to fall one by one into the through slot by their own weight. A lifting and rotating mechanism is located below the conveying surface of the conveyor within the frame. This mechanism lifts the iron core on the conveying surface of the conveyor to align with the bottom of the material channel positioning fixture and drives the iron core to rotate, causing the set of magnet slots to alternately align with the set of through slots, ensuring that one magnet is inserted into each magnet slot.

[0007] Preferably, the material channel positioning fixture includes a material channel positioning plate and an iron core positioning disc. The top edge of the material channel positioning plate is recessed with two slots. The top of the frame is correspondingly provided with a pivotable limiting block. The limiting block engages or disengages with the slots by rotation to lock or unlock the connection between the material channel positioning fixture and the frame. The bottom of the material channel positioning plate protrudes downwards and outwards. The top of the frame is provided with a mounting hole that matches the bottom of the material channel positioning plate. The bottom of the material channel positioning plate is embedded in the mounting hole.

[0008] Preferably, a connecting shaft passes through the axis of the iron core positioning disk, and the connecting shaft is pivotally connected to the material channel positioning plate, so that the iron core positioning disk can rotate relative to the material channel positioning plate. The iron core positioning disk is provided with docking holes that correspond one-to-one with a set of magnet slots. A positioning block is provided at the bottom of the iron core positioning disk, and a limit hole is provided on the iron core to engage with the positioning block, so that the iron core and the iron core positioning disk are docked as one and rotate synchronously. When the iron core is docked with the iron core positioning disk, the set of magnet slots and the set of docking holes are connected vertically.

[0009] Preferably, a set of the through slots is built into the material channel positioning plate, and the number of a set of docking holes and magnetic slots is an integer multiple of the number of a set of through slots. The iron core positioning plate rotates synchronously with the iron core to switch the docking holes and magnetic slots with the set of through slots. A connecting locking block is provided on the top side of the through slot. The bottom end of the material channel is inserted into the through slot, and the bottom end of the material channel has a stepped surface. A limit screw is provided on the top of the connecting locking block to abut against the stepped surface to limit the bottom end of the material channel within the through slot.

[0010] Preferably, the material channel positioning fixture further includes a positioning pin. The material channel positioning plate and the iron core positioning plate are respectively provided with a first insertion hole and a second insertion hole that match the positioning pin. When the material channel positioning fixture is initially connected to the frame, the positioning pin passes through the first insertion hole and the second insertion hole from top to bottom through the material channel positioning plate and the iron core positioning plate to limit the initial rotation position of the iron core positioning plate. When the material channel positioning fixture is working connected to the frame, the positioning pin is pulled out.

[0011] Preferably, the iron core positioning disk is provided with a positioning hole on its side, the positioning hole marks the initial rotation position of the iron core positioning disk, and a positioning cylinder is fixedly provided on the top back of the frame. The front end of the drive rod of the positioning cylinder is provided with a positioning rod that matches the positioning hole. The positioning rod is inserted into the positioning hole to drive the iron core positioning disk back to the initial rotation position.

[0012] Preferably, the lifting and rotating mechanism includes a rotating module and a lifting module. The lifting module includes a lifting plate and lifting cylinders. Two lifting cylinders are disposed on the top of the support frame, and the driving ends of the two lifting cylinders are respectively fixed to the bottom of the lifting plate to drive the lifting plate to move up and down. Guide rods are also provided between the four corners of the lifting plate and the support frame. The rotating module includes a servo motor and a positioning plate. The bottom of the positioning plate is coaxially disposed on the top of the lifting plate through a bearing. The servo motor is connected to the bottom of the lifting plate so that the rotating module moves up and down synchronously with the lifting plate. The axis of the positioning plate is hollow to avoid the driving end of the servo motor.

[0013] Preferably, a carrier plate is slidably disposed on the conveying surface of the conveyor line, a positioning seat is disposed on the carrier plate to limit the iron core, a stop is disposed on the conveyor line to limit the carrier plate within the frame, a positioning post is disposed on the corner of the positioning plate to engage with the bottom of the carrier plate to lift the carrier plate to lift and rotate synchronously, and a detection sensor for detecting the iron core is disposed on the side of the frame.

[0014] Preferably, the device further includes a connecting bracket, which includes a first fixed end and a second fixed end. The material channel is defined at the top of the first fixed end and the second fixed end and extends downward at an angle. The cutting mechanism is disposed on the second fixed end and includes two driving cylinders, a first cutting rod, a second cutting rod, and a sensor. An opening is provided at the bottom of the material channel. The bottoms of the first cutting rod and the second cutting rod are respectively connected to one of the driving cylinders and are driven by the driving cylinders to alternately insert into the opening to limit the single falling of the magnet in the material channel. Through holes are provided on both sides of the material channel at the opening. Two sensors are respectively located outside one of the through holes to detect the magnet in the material channel.

[0015] Preferably, a locking groove is provided at the top of the first fixed end and the second fixed end respectively, the support groove is engaged at the bottom of the material channel, and the two ends of the support groove are engaged at the bottom of the two locking grooves. A fixing screw and a locking block are provided at the top of the locking groove. The locking block and the support groove cooperate to define the position of the material channel. A top block is also elastically provided in the locking groove of the second fixed end. A spring abuts between the bottom of the top block and the top of the second fixed end. The top block abuts against the support groove under the drive of the spring.

[0016] The beneficial effects of this invention are mainly reflected in:

[0017] 1. A material channel positioning fixture is set on the frame to simultaneously connect the conveyor line for feeding iron cores and the magnet feeding mechanism for feeding magnets, replacing the traditional gripping method of the robotic arm. The material channel allows the magnets to fall freely under their own weight, which saves power, simplifies the structure, and ensures the integrity of the magnets. A lifting and rotating mechanism is set to drive the iron core to connect with the material channel positioning fixture, and through rotation, the material channel, through slot, and magnet slot are connected in sequence to realize the rapid insertion of all magnets and improve the insertion efficiency.

[0018] 2. The number of a set of mating holes and magnet slots is an integer multiple of the number of a set of through slots, so that the iron core can be rotated an integer multiple of the number of magnets to complete the insertion of all magnets, without having to open through slots with the same number of magnet slots, simplifying the equipment structure and reducing the manufacturing difficulty of the equipment.

[0019] 3. The material channel positioning fixture engages or disengages with the slot by rotating the limit block to lock or unlock the material channel positioning fixture, thereby realizing a quick-release connection between the material channel positioning fixture and the frame. This facilitates quick replacement of the material channel positioning fixture to adapt to magnets of different sizes without replacing the overall structure, forming flexible manufacturing and improving the flexibility and convenience of actual use.

[0020] 4. The first and second fixed ends are fitted with slots to fit the material channel, avoiding the distortion and bending of the inner contour of the material channel caused by direct engagement, ensuring the fit between the inner contour of the material channel and the magnet, and a pivotable locking block is provided to conveniently and quickly limit or release the material channel, facilitating the disassembly and assembly of the material channel and improving ease of use.

[0034] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments are not limited to the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the scope of protection of the present invention.

[0035] In the description of the solution, it should be noted that the terms "center," "upper," "lower," "left," "right," "front," "rear," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience and simplification of description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Also, in the description of the solution, with the operator as a reference, the direction closer to the operator is the proximal end, and the direction farther from the operator is the distal end.

[0036] like Figures 1 to 12As shown, this invention discloses an automatic magnet insertion device, including a conveyor line 2 for conveying iron cores 6 and a frame 1 mounted on the conveyor line 2. The iron core 6 has a set of magnet slots 601 for inserting magnets. A material channel positioning fixture 3 is detachably provided on the top of the frame 1. A set of through slots 300 vertically arranged within the material channel positioning fixture 3 communicates with the magnet slots 601. A set of magnet feeding mechanisms 4 are arranged around the outer periphery of the frame 1. Each magnet feeding mechanism 4 is connected to the iron core 6 via a magnet-flowing material channel 5. The channels 300 are connected, and the top of the material channel 5 is provided with a cutting mechanism to allow a group of magnets to fall into the channel 300 one by one by their own weight; the frame 1 is provided with a lifting and rotating mechanism located below the conveying surface of the flow line 2 to lift the iron core 6 on the conveying surface of the flow line 2 to dock with the bottom of the material channel positioning fixture 3, and drive the iron core 6 to rotate so that a group of magnet slots 601 are alternately docked with a group of channels 300, so that a magnet is inserted into each magnet slot 601.

[0037] In this solution, the frame 1 is equipped with a material channel positioning fixture 3 to simultaneously connect the flow line 2 for feeding iron cores and the magnet feeding mechanism 4 for feeding magnets, replacing the traditional gripping method of the robotic arm. The material channel 5 allows the magnets to fall freely under their own weight, which saves power, simplifies the structure, and ensures the integrity of the magnets. A lifting and rotating mechanism is set up to drive the iron core 6 to connect with the material channel positioning fixture 3, and through rotation, it sequentially connects the material channel 5, the through slot 300, and the magnet slot 601, realizing the rapid insertion of all magnets and improving the insertion efficiency.

[0038] like Figures 3-5 As shown, the material channel positioning fixture 3 includes a material channel positioning plate 301 and an iron core positioning plate 302. The top edge of the material channel positioning plate 301 is provided with two grooves 3012. The top of the frame 1 is correspondingly provided with a pivotable limiting block 102. The limiting block 102 engages or disengages with the grooves 3012 by rotation to lock or unlock the connection between the material channel positioning fixture 3 and the frame 1. The bottom of the material channel positioning plate 301 protrudes downward and outward. The top of the frame 1 is provided with a mounting hole 101 that matches the bottom of the material channel positioning plate 301. The bottom of the material channel positioning plate 301 is embedded in the mounting hole 101. This structural design enables a quick-release connection between the material channel positioning fixture 3 and the frame 1, facilitating rapid replacement of the material channel positioning fixture 3 and allowing for the replacement of different sized through slots 300 to accommodate magnets of varying sizes, without requiring a complete overhaul of the overall structure. This flexible manufacturing approach enhances the flexibility and convenience of practical use. To further facilitate the installation of the material channel positioning plate 301, handles are provided on both sides of its top.

[0039] A connecting shaft 303 passes through the axis of the iron core positioning disk 302. The connecting shaft 303 is pivotally connected to the material channel positioning plate 301, so that the iron core positioning disk 302 can rotate relative to the material channel positioning plate 301. The iron core positioning disk 302 is provided with docking holes 3021 that correspond one-to-one with a set of magnet slots 601. A positioning block 3022 is provided at the bottom of the iron core positioning disk 302. The iron core 6 is provided with a limit hole 602 to engage with the positioning block 3022, so that the iron core 6 and the iron core positioning disk 302 are docked together and rotate synchronously. When the iron core 6 and the iron core positioning disk 302 are docked, the set of magnet slots 601 and the set of docking holes 3021 are connected one-to-one. Preferably, the bottom diameter of the connecting shaft 303 is larger than its rod portion, so that the bottom of the connecting shaft 303 can support the iron core positioning disk 302, and the bottom of the connecting shaft 303 is adapted to the hollow inner diameter of the iron core 6. When the iron core 6 and the iron core positioning disk 302 are docked, the two can fit together more tightly.

[0040] Furthermore, a set of through slots 300 are built into the material channel positioning plate 301. The number of a set of docking holes 3021 and magnet slots 601 is an integer multiple of the number of through slots 300. The iron core positioning plate 302 rotates synchronously with the iron core 6 to switch the docking holes 3021 and magnet slots 601 with the through slots 300. A connecting locking block 306 is provided on the top side of the through slot 300. The bottom end of the material channel 5 is inserted into the through slot 300, and the bottom end of the material channel 5 has a stepped surface 501. A limit screw 3061 is provided on the top of the connecting locking block 306 to abut against the stepped surface 501 to limit the bottom end of the material channel 5 within the through slot 300. This structural arrangement allows the iron core 6 to rotate an integer multiple to complete the insertion of all magnets without having to open through slots 300 with the same number of magnet slots 601, simplifying the equipment structure and reducing the manufacturing difficulty of the equipment. The arrangement of the magnet slots 601 on the iron core 6 is regular, such as... Figure 6 As shown in the illustrated embodiment, the iron core 6 has eight identical magnet units composed of magnet slots 601 in three different orientations. Therefore, only three through slots 300 corresponding to the three magnet slots 601 in different orientations need to be provided, and the insertion of all magnet slots 601 can be completed by rotating eight times. The number of through slots 300 depends on the number of magnet slots 601 in different orientations, and can be three, four, etc. The number of feed channels 5 depends on the number of through slots 300. Figure 1 The diagram shown illustrates a partially installed feeder system with three or four feeders to choose from; the user can select the option that best suits their needs. Figure 2The diagram shown is a schematic of the three material channels after they are connected.

[0041] Preferred, such as Figure 5 and Figure 7 As shown, in order to facilitate the smooth descent of the magnet under its own weight, the inner diameter of the through groove 300 and the docking hole 3021 gradually decreases from top to bottom, and their sidewalls form inclined sidewalls to accelerate the descent of the magnet.

[0042] Furthermore, since the core positioning disk 302 can rotate relative to the channel positioning plate 301, in the initial state where the channel positioning fixture 3 is installed but not used, the relative position between the core positioning disk 302 and the channel positioning plate 301 is uncertain, and the core positioning disk 302 may rotate to any angle.

[0043] Therefore, the material channel positioning fixture 3 also includes a positioning pin 304. The material channel positioning plate 301 and the iron core positioning disk 302 are respectively provided with a first insertion hole and a second insertion hole that match the positioning pin 304. When the material channel positioning fixture 3 is initially connected to the frame 1, the positioning pin 304 passes through the first insertion hole and the second insertion hole from top to bottom through the material channel positioning plate 301 and the iron core positioning disk 302 to limit the initial rotation position of the iron core positioning disk 302, so as to ensure that the initial rotation position of the iron core positioning disk 302 after docking with the iron core 6 is consistent, and thus completes the insertion of all magnets by rotating by the same angle. The positioning pin 304 is only used to control the stability of the relative position between the iron core positioning disk 302 and the material channel positioning plate 301 in the initial state after installing or replacing the material channel positioning fixture 3. Therefore, when the material channel positioning fixture 3 is connected to the frame 1 in the working state, the positioning pin 304 can be pulled out. To prevent the positioning pin 304 from being lost, the top corner of the frame 1 is provided with a matching pin hole for placing the positioning pin 304.

[0044] Furthermore, the iron core positioning disk 302 is provided with a positioning insertion hole 3023 on its side. The positioning insertion hole 3023 marks the initial rotation position of the iron core positioning disk 302. A positioning cylinder 305 is fixedly installed on the top back of the frame 1. The front end of the drive rod of the positioning cylinder 305 is provided with a positioning insertion rod 3051 that matches the positioning insertion hole 3023. The positioning insertion rod 3051 is inserted into the positioning insertion hole 3023 to drive the iron core positioning disk 302 back to the initial rotation position. This structural arrangement is designed so that, in continuous use without changing the material channel positioning fixture 3, after each iron core 6 magnet insertion process is completed, the positioning insertion rod 3051 is inserted into the positioning insertion hole 3023 to ensure that the iron core positioning disk 302 returns to its initial rotation position before the next iron core 6 magnet insertion process.

[0045] The lifting and rotating mechanism includes a rotating module and a lifting module. The lifting module includes a lifting plate 703 and lifting cylinders 704. Two lifting cylinders 704 are disposed on the top of the support frame 700. The driving ends of the two lifting cylinders 704 are respectively fixed to the bottom of the lifting plate 703 to drive the lifting plate 703 to move up and down. Guide rods 706 are also provided between the four corners of the lifting plate 703 and the support frame 700. The rotating module includes a servo motor 701 and a positioning plate 702. The bottom of the positioning plate 702 is coaxially disposed on the top of the lifting plate 703 through a bearing 705. The servo motor 701 is connected to the bottom of the lifting plate 703 so that the rotating module moves up and down synchronously with the lifting plate 703. The axis of the positioning plate 702 is hollow to avoid the driving end of the servo motor 701. This structural design makes the lifting and rotating mechanism more compact and smaller in size. The lifting module can simultaneously drive the synchronous lifting and lowering of the rotating module and the iron core 6, resulting in higher overall consistency. It eliminates the need for a separate lifting mechanism for the rotating module, simplifying the equipment structure and ensuring the stability of the iron core 6 during the lifting process. Furthermore, it allows the rotating module to automatically align with the bottom of the iron core 6 for rotation, making the production cycle of lifting and rotating the iron core 6 smoother and more efficient.

[0046] Specifically, a carrier tray 201 is slidably disposed on the conveying surface of the flow line 2. A positioning seat 202 is provided on the carrier tray 201 to constrain the iron core 6. A stopper 203 is provided on the flow line 2 to confine the carrier tray 201 within the frame 1. Positioning posts 7021 are provided on the corners of the positioning plate 702 to engage with the bottom of the carrier tray 201, thereby lifting the carrier tray 201 to synchronously lift, lower, and rotate. The flow line 2 is existing technology and also includes necessary components such as a motor, which are not the focus of this solution and will not be elaborated here.

[0047] To prevent the entire machine from spinning without the iron core 6 being inserted, a detection sensor 9 for detecting the iron core 6 is provided on the side of the frame 1.

[0048] Furthermore, it also includes a connecting bracket 801 for fixing the top end of the material channel 5 and setting the cutting mechanism. The connecting bracket 801 includes a first fixed end 8011 and a second fixed end 8012. The first fixed end 8011 is higher than the second fixed end 8012 and shorter than the second fixed end 8012, so that the material channel 5 is limited to the top of the first fixed end 8011 and the second fixed end 8012 and extends downward at an angle.

[0049] The cutting mechanism is mounted on the second fixed end 8012. The cutting mechanism includes two drive cylinders 802, a first cutting rod 803, a second cutting rod 804, and a sensor 805. An opening 502 is provided at the bottom of the material channel 5. The bottoms of the first cutting rod 803 and the second cutting rod 804 are respectively connected to one of the drive cylinders 802 and are driven by the drive cylinders 802 to alternately insert into the opening 502, thereby limiting the individual falling of magnets within the material channel 5. Through holes 504 are provided on both sides of the material channel 5 at the opening 502. Two sensors 805 are located outside one of the through holes 504 to detect magnets within the material channel 5. The distance between the tops of the first cutting rod 803 and the second cutting rod 804 is not less than the length of one magnet and not greater than the length of two magnets. The cutting mechanism operates as follows: In the initial state, the first cutting rod 803 extends into the opening 502, while the second cutting rod 804 remains closed. When a set of magnets falls into the opening 502, the first magnet is blocked by the top of the first cutting rod 803, and the two come into contact. At this point, the sensor 805 detects the magnet. In the second state, the second cutting rod 804 extends into the opening 502, pressing against the second magnet. Subsequently, the first cutting rod 803 retracts outside the opening 502, releasing the obstruction of the first magnet. At this point, the first magnet falls freely along the feed channel 5 under its own gravity, while the second magnet is confined by the second cutting rod 804. The first cutting rod 803 and the second cutting rod 804 continuously switch positions to extend into the opening 502 to complete the cutting process of a set of magnets falling one by one.

[0050] Furthermore, a locking groove 806 is provided on the top of the first fixed end 8011 and the second fixed end 8012 respectively, and a support groove 807 is engaged at the bottom of the material channel 5. The two ends of the support groove 807 are engaged at the bottom of the two locking grooves 806. A fixing screw 809 and a locking block 808 that is engaged with the fixing screw 809 by pivoting are provided on the top of the locking groove 806. The locking block 808 and the support groove 807 cooperate to define the position of the material channel 5. The first fixed end 8011 and the second fixed end 8012 are fitted with a slot 807 to fit the material channel 5, avoiding direct clamping of the material channel 5 and causing distortion and bending of the inner contour of the material channel 5, ensuring the fit between the inner contour of the material channel 5 and the magnet, so as to ensure the smooth falling of the magnet; the locking block 808 can quickly open or close the locking groove 806 to clamp or release the material channel 5, which facilitates the disassembly and replacement of the material channel 5 to adapt to the falling requirements of magnets of different sizes and improves the ease of use.

[0051] A top block 810 is also elastically provided in the locking groove 806 of the second fixed end 8012. A spring 811 abuts between the bottom of the top block 801 and the top of the second fixed end 8012. The top block 801 abuts against the support groove 807 under the drive of the spring 811 to ensure the tight connection between the support groove 807 and the material channel 5.

[0052] The magnet feeding mechanism 4 is a vibratory feeder, which uses vibration to select magnets by direction, allowing the magnets with the confirmed direction to fall into the feed channel 5. The specific structure of the vibratory feeder is existing technology and is not the focus of this solution, so it will not be described in detail here.

[0053] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0054] The detailed descriptions listed above are merely specific descriptions of feasible embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. All equivalent embodiments or modifications made without departing from the spirit of the present invention should be included within the scope of protection of the present invention.
