Description

Technical Field

[0001] This invention relates to the field of iron core production, and more particularly to an automated progressive die production system that improves processing efficiency. Background Technology

[0002] Electric motors are key power components in modern industry and consumer electronics. The stator and rotor cores are their core constituents, and their manufacturing quality and efficiency directly affect motor performance and production costs. Currently, progressive dies have become the preferred process for mass production of stator and rotor core laminations due to their high precision, high efficiency, and ability for continuous automated production. A single progressive die can complete multiple processes such as punching, forming, and stamping on a production line, directly converting coiled material into single core laminations, resulting in fast production cycles and high material utilization.

[0003] However, in existing technologies, progressive die production systems typically face a critical efficiency bottleneck and automation gap after stamping the core laminations: the core stacking stage. Traditional production processes generally exhibit the following two modes: 1. Separate Production Mode: Progressive dies are used to stamp individual blanks at high speed. These blanks are then collected by a collection device or manually and transferred to another independent dedicated stacking equipment or station for core stacking and riveting. This mode has significant drawbacks: First, material transfer between processes (including handling, stacking, and reloading) not only increases the production cycle but also easily causes damage, deformation, or oil contamination to the precision blanks. Second, the overall production line layout is dispersed, occupying a large space and requiring more operators or robots for coordination, increasing labor costs and management complexity. Finally, production rhythm is difficult to synchronize; the advantages of high-speed stamping are offset by the low-speed, intermittent stacking process, limiting overall production efficiency.

[0004] 2. Semi-automatic integration mode: Some advanced systems attempt to integrate simple collection or pre-stacking devices at the end of the progressive die, but their function is often limited to arranging laminations into stacks or performing preliminary, unstable stacking. For stator and rotor cores with stringent requirements (especially those requiring rotating laminations to optimize the magnetic circuit and ensure slot alignment), existing integration solutions are generally difficult to implement.

[0005] As the motor industry moves towards higher efficiency and large-scale customization, the market is placing higher demands on the production of stator and rotor cores: achieving higher production cycles, lower unit costs, and more flexible production response capabilities while ensuring high precision and high quality. Therefore, seamlessly integrating the two core processes of high-speed stamping of core laminations with high-precision, high-reliability automated stacking to form a truly coherent and efficient automated production system has become a pressing technical challenge.

[0016] The beneficial effects of the technical solutions provided in the embodiments of the present invention include at least the following: (1) The automated progressive die production system of the present invention improves processing efficiency. It has a reasonable structural design, high degree of automation, high production efficiency, and high quality and precision of the automatically stacked rotor core and stator core.

The first blanking stacking component is on the lower base of the progressive die and can automatically collect the rotor iron chips after blanking and automatically stack a predetermined number of the collected rotor iron chips into a rotor core. The second blanking stacking component is on the lower base and can automatically collect the stator iron chips after blanking and automatically stack a predetermined number of the collected stator iron chips into a stator core. This completely eliminates the process breakpoint between stamping and stacking in the traditional production mode, and seamlessly integrates high-speed stamping and synchronous stacking into the same system, realizing uninterrupted continuous production.

[0022] In this embodiment of the invention, sometimes a subscript such as W1 may be written in a non-subscript form such as W1. When the difference is not emphasized, the meaning they express is the same.

[0023] To make the technical problems, technical solutions and advantages of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0024] according to Figures 1-18 As shown, an automated progressive die production system for improving processing efficiency includes a feeding component, a stamping component, and a finished product processing component, which are respectively arranged on the ground. The feeding component includes an uncoiler 1 and a leveler 2, which are respectively arranged on the ground.

[0025] The uncoiler 1 is equipped with a silicon steel sheet coil 3 and has a tension control function for carrying and unwinding the silicon steel sheet. The leveler 2 is used to eliminate the bending and internal stress of the silicon steel sheet and to provide a flat silicon steel sheet strip 44 to the stamped parts, thereby improving the stamping accuracy.

[0026] The stamping part includes a feeding component 4 and a stamping component, which are correspondingly arranged on the ground. The feeding component 4 can intermittently and accurately feed the silicon steel sheet after leveling by the uncoiler 1 into the stamping component at a constant step distance. The stamping component includes a machine tool 5 and a progressive die 6. The machine tool 5 is distributed on the ground corresponding to the feeding component 4, and the progressive die 6 is arranged on the machine tool 5 to punch the strip 44. The progressive die 6 includes an upper die holder 7 and a lower die holder 8. The upper die holder 7 is mounted on the slide of the machine tool 5, and the lower die holder 8 is mounted on the worktable of the machine tool 5.

[0027] The finished product processing component includes a first blanking stacking component and a second blanking stacking component. The first blanking stacking component is located on the lower base 9 of the lower die holder 8 and is used to collect rotor iron chips 11 that have been punched and blanked from the strip 44, and automatically stack a predetermined number of the collected rotor iron chips 11 into a rotor core. The second blanking stacking component is located on the lower base 9 and is used to collect stator iron chips 12 that have been punched and blanked from the strip 44, and automatically stack a predetermined number of the collected stator iron chips 12 into a stator core. It should be noted that the lower base 9 is generally hollow, which is used to improve support for the lower die holder 8 and facilitate the discharge of the punched scrap plates after they fall downwards.

[0028] The first unloading stacking component includes a first unloading receiving component, a first unloading stacking component, a first quick-drying component, and a first iron core transfer component. The first unloading receiving component is located inside the lower base 9 and receives the rotor iron chips 11 under unloading. The first unloading stacking component is located in the inner cavity of the base of the machine tool 5 and is correspondingly positioned directly below the first unloading receiving component to tightly stack multiple rotor iron chips 11 within the first unloading receiving component. The first quick-drying component is located on the first unloading receiving component and is used to blow hot air onto the upper surface of the rotor iron chips 11 received in the first unloading receiving component to accelerate the curing of the adhesive. The first iron core transfer component is located inside the lower base 9 and is used to transfer a predetermined number of rotor iron cores stacked on the first unloading stacking component to the outside of the machine tool 5 as needed.

[0029] The first blanking receiving component includes a first support base 13, a first receiving layer component, a first adhesive dispensing component, and a first positioning component. The first support base 13 is disposed on the lower base 9 to provide support. The first receiving layer component is disposed on the first support base 13 and is used to successively receive multiple rotor iron chips 11 and layer the multiple rotor iron chips 11. The first adhesive dispensing component is disposed on the first receiving layer component and is used to spray adhesive onto the upper surface of the multiple rotor iron chips 11. The inner wall of the first support base 13 is cylindrical, and the diameter of the inner wall of the first support base 13 is not less than the diameter of the rotor iron chip 11. The top port of the first support base 13 is aligned with the cavity of the die 10 of the lower die base 8 so that the blanked rotor iron chips 11 are pushed into the inner cavity of the first support base 13, and the rotor iron chips 11 entering the inner cavity of the first support base 13 are horizontally received by the first receiving layer component.

[0030] The first receiving layer component includes a layering seat 14, a limiting block, and a ferromagnetic component. The layering seat 14 is rotatably mounted in a receiving groove 16 on the inner wall of the first support seat 13 via a rotating shaft at its bottom. The limiting block is triangular in shape and is fixedly mounted on the bottom surface of the groove opening of the receiving groove 16 to limit the rotation angle of the layering seat 14 into the inner cavity of the first support seat 13 (when the layering seat 14 rotates towards the inner cavity of the first support seat 13 and abuts against the limiting block, the top surface of the first layering plate is horizontal and used to horizontally receive the rotor iron chip 11). The ferromagnetic component is mounted on the receiving groove 16 and is used to generate a magnetic field when energized to completely confine the layering seat 14 within the receiving groove 16, or to generate a magnetic field when energized to rotate and push the top of the layering seat 14 into the inner cavity of the first support seat 13.

[0031] The ferromagnetic components include an electromagnet 17 and a permanent magnet 18. The electromagnet 17 is fixedly disposed on the bottom surface of the receiving groove 16, and the permanent magnet 18 is fixedly disposed on the layered seat 14, with the electromagnet 17 and the permanent magnet 18 corresponding to each other. When the layered seat 14 is pushed upward from below, the top surface of the layered seat 14 will rotate and completely enter the receiving groove 16. At this time, a positive current is passed through the electromagnet 17, causing the permanent magnet 18 to attract onto the electromagnet 17, thereby locking the layered seat 14 within the receiving groove 16. When the layered seat 14 needs to unfold outward to receive the rotor iron chip 11, a reverse current is passed through the electromagnet 17 to push the permanent magnet 18 outward, causing the top surface of the layered seat 14 to rotate and unfold towards the inner cavity of the first support seat 13.

[0032] The first receiving layer component comprises sixteen sets, which are divided into four groups (each group has four sets of the first receiving layer component). The four groups of the first receiving layer component are evenly spaced along the axial direction of the first receiving seat, and the four sets of the first receiving layer component in each group are evenly spaced along the horizontal circumferential direction of the first receiving seat (each group of four sets of the first receiving layer component is used to simultaneously receive one rotor iron chip 11). It should be noted that the first adhesive dispensing component in the bottommost group of the first receiving layer component is used to spray adhesive onto the upper surface of the rotor iron chip 11 on the first unloading stack component.

[0033] The first dispensing component includes an actuator, a fluid management module, and a drive and control mechanism. The spray valve 19 of the actuator is disposed within the layering seat 14, and the nozzle of the spray valve 19 corresponds to the spray port on the inclined surface of the layering seat 14, for spraying adhesive from the spray port onto the upper surface of the rotor iron chip below. The fluid management module is connected to the spray valve 19 via a hose (the hose allows the layering seat 14 to swing within the receiving groove 16), for supplying adhesive to the spray valve 19. The drive and control mechanism is connected to the fluid management module, providing it with power. Since the first dispensing component uses existing technology, it will not be described in detail here. Furthermore, multiple sets of spray valves 19 are provided, each set corresponding to one of the multiple layering seats 14, for uniformly and symmetrically spraying adhesive onto the rotor iron chip 11 circumferentially.

[0034] The first positioning component includes a first circumferential rotating component and a first circumferential positioning component. The first circumferential rotating component is on the first support base 13 and can drive the connected first circumferential positioning component to rotate circumferentially. The first circumferential positioning component positions the rotor iron chip 11 circumferentially on the first circumferential rotating component and drives the rotor iron chip 11 to rotate circumferentially by a multiple of 90 degrees.

[0035] The first circumferential rotating component includes a circumferential rotating ring 20 and a power component 21. The circumferential rotating ring 20 is circumferentially fitted into a rotating groove 46 on the inner wall of the first support base 13. The power component 21 is connected to the circumferential rotating ring 20 on the first support base 13 to drive the circumferential rotating ring 20 to rotate circumferentially. Alternatively, the rotating groove 46 is generally annular, with its axis coinciding with the axis of the first support base 13, and its cross-section is T-shaped. The rotating groove 46 is located between the upper and lower sets of the first receiving layer components.

[0036] The power component 21 includes a drive shaft, a gear, and a motor. One end of the drive shaft rotatably passes through the side wall of the first support base 13. The gear is fixedly mounted on one end of the drive shaft and meshes with the gear teeth on the side of the circumferential rotating ring 20. The motor is fixedly mounted on the first support base 13, and the motor's shaft is connected to the other end of the drive shaft. When the motor drives the gear to rotate via the drive shaft, it will drive the circumferential rotating ring 20 to rotate.

[0037] The first circumferential positioning component includes a transmission rod 22, a sliding tube 23, a magnetic coil, and a positioning block 24. One end of the transmission rod 22 slides horizontally through the opening of the rotating groove 46 and is fixedly mounted on the circumferential rotating ring 20. One end of the sliding tube 23 is axially slidably fitted onto the other end of the transmission rod 22. The magnetic coil is fixedly embedded in a spiral groove on the inner wall of the sliding tube 23 (the axial projection of the spiral groove is rectangular). The positioning block 24 is triangular in shape, with its bottom surface horizontally fixed on the other end of the sliding tube 23. The longitudinal line of the positioning block 24 is parallel to the axis of the first support base 13, and the height of the bottom surface of the positioning block 24 is not less than the height of the top surface of the layered seat 14, so that the positioning block 24 can clamp and rotate the rotor iron chip 11 circumferentially. The length of the transmission rod 22 is greater than the length of the top surface of the layered seat 14 extending into the first support base 13.

[0038] When a positive direct current is passed into the magnetic coil to generate a magnetic field, the sliding tube 23 will be pushed to slide outward. The sliding tube 23, which slides outward, will drive the positioning block 24 to move in the axial direction of the first support seat 13 until the top triangular face of the positioning block 24 is in the groove of the rotor iron core 11 (the angle of the top triangular face of the positioning block 24 is the same as the opening angle of the groove of the rotor iron core).

[0039] Four sets of the first circumferential positioning components are provided, and the four sets of the first circumferential positioning components are evenly distributed along the circumferential rotation ring 20. The four sets of the first circumferential positioning components simultaneously push against the four slots on the rotor iron chip 11 to position the rotor iron chip 11 circumferentially. And as the circumferential rotation ring 20 rotates, it drives the rotor iron chip 11 to rotate circumferentially.

[0040] It should be noted that after the first circumferential positioning component drives the rotor iron chip 11 to rotate at equal angles and then stacks them together, it can reduce the thickness unevenness error and flatness error of the rotor iron chip 11, thereby effectively improving the thickness uniformity of the stacked rotor iron core and reducing the total height error of the rotor iron core.

[0041] The first positioning component is provided in three sets, and the three sets of the first positioning component are equally spaced along the axial direction of the first support base 13, so as to position and rotate the rotor iron chip 11 supported on the first receiving layer component below.

[0042] The first blanking stacking component includes a first linear actuator 25, a receiving tube 26, a receiving plate 27, and a spring 28. The bottom end of the first linear actuator 25 is fixedly mounted on the machine tool 5, and the first linear actuator 25 is located directly below the first support base 13. One end of the receiving tube 26 is axially slidably fitted onto the top end of the telescopic rod of the first linear actuator 25. The receiving plate 27 is horizontally fixedly mounted on the other end of the receiving tube 26. The spring 28 is embedded in the receiving tube 26, with one end connected to the top surface of the telescopic rod and the other end connected to the bottom surface of the receiving plate 27. When the first linear actuator 25 extends, it can drive the receiving plate 27 to move upward within the first support base 13, thereby bonding and stacking the three rotor iron chips 11 held on the first receiving stacking component and the one rotor iron chip 11 that has just been punched together. Alternatively, the receiving plate 27 is magnetic to increase the bonding stability of the first rotor magnet sheet and improve the overall stacking accuracy.

[0043] The first quick-drying component includes a hot air delivery pipe 29, a hot air delivery main pipe 45, and a hot air blower. The hot air delivery pipe 29 is rectangular in shape, and its sidewall is disposed through the sidewall of the first support base 13. The hot air delivery pipe 29 communicates with hot air holes 30 within the first support base 13. The hot air holes 30 are annular in shape, and four hot air holes 30 are provided. The four hot air holes 30 are evenly spaced along the axial direction of the first support base 13, and all four hot air holes 30 communicate with the hot air delivery pipe 29. One end of the hot air delivery main pipe 45 passes through the lower base 9 and communicates with the hot air delivery pipe 29. The hot air blower is connected to the other end of the hot air delivery main pipe 45 and is used to deliver hot air to the hot air delivery main pipe 45. Alternatively, the hot air blower can be installed on the rear side of the lower base 9 or the machine tool 5, or it can be installed on the ground to heat the outside clean air and deliver it to the hot air delivery main duct 45.

[0044] A hot air support hole is provided on the inner wall of the first support base 13. One end of the hot air support hole communicates with the hot air hole 30, and the other end of the hot air support hole faces the upper surface of the rotor iron chip 11. Furthermore, the position where the other end of the hot air support hole blows towards the rotor iron chip 11 is the same as the position where the first adhesive part is sprayed towards the rotor iron chip 11, so as to accelerate the solidification speed of the adhesive on the rotor iron chip 11.

[0045] Multiple hot air support holes are provided, and these multiple hot air support holes are divided into four groups. The four groups of hot air support pipes correspond one-to-one with the four hot air holes 30, and the multiple hot air support holes in each group correspond to the layered seat 14. This ensures that at least one hot air support hole blows hot air at the location where the first adhesive component is sprayed onto the rotor iron chip 11.

[0046] A through hole 31 is provided on the receiving plate 27 between the outer ring of the receiving pipe 26 and the inner ring of the rotor iron core 11. Multiple through holes are used to discharge a portion of the hot air inside the first support base 13 outwards through the through holes. A spiral groove 32 is provided on the inner wall of the bottom end of the first support base 13. The total length of the spiral groove 32 is not less than the length of the rotor iron core. The spiral groove 32 is used to discharge another portion of the hot air inside the first support base 13 outwards through the spiral groove 32. Through the guiding effect of the through hole 31 and the spiral groove 32, the multiple rotor iron cores 11 stacked together can still be dried by the hot air along the inner and outer rings, improving the mutual adhesion when pushed out of the rotor iron core. Alternatively, the multiple spiral grooves 32 are evenly distributed circumferentially.

[0047] The first core transfer component includes a conveyor 33 and a second linear actuator 34. One end of the conveyor 33 passes through the output through-hole on the lower base 9 and extends to the side of the first linear actuator 25. The second linear actuator 34 is horizontally fixed on the lower base 9. A push plate 35 is provided at the top of the telescopic rod of the second linear actuator 34. The push plate 35 is in the shape of an arc plate. When a predetermined number of rotor core chips 11 are bonded and stacked on the first unloading stack, the first linear actuator 25 shortens, causing the rotor core to completely retract from the first support base 13. At this time, the second linear actuator 34 extends, horizontally pushing the rotor core from the receiving plate 27 onto the conveyor 33 for transfer.

[0048] The method of using the first blanking stack is as follows (this method takes the stacking of a rotor core as an example): 1) The first linear actuator 25 pushes the receiving plate 27 upward within the first support base 13 to a predetermined height, at which time the strip 44 performs a punching operation; the punched rotor iron chip 11 falls horizontally onto the receiving plate 27. 2) The first linear actuator 25 drives the receiving plate 27 and the first rotor iron chip 11 to descend (during the descent, the layered seat 14 retracts into the receiving groove 16). 3) When the receiving tray 27 descends to below the first receiving layer of the lowest first group, the layer seat 14 of the first receiving layer of the lowest first group unfolds from the receiving groove 16 (the unfolded layer seat 14 is used to receive the second rotor iron chip 11 that has been punched out, and also to allow the spray valve 19 in the layer seat 14 to spray glue onto the upper surface of the first rotor iron chip 11, and the first quick-drying component blows hot air onto the upper surface of the rotor iron chip 11). 4) When the second rotor iron chip 11 is horizontally supported on the first receiving layer of the lowest first group, the layer seat 14 of the second group of first receiving layer above unfolds from the receiving groove 16 (the unfolded layer seat 14 is used to receive the third rotor iron chip 11 that has been punched out, and also to allow the spray valve 19 in the layer seat 14 to spray glue onto the upper surface of the second rotor iron chip 11, and the first quick-drying component blows hot air onto the upper surface of the rotor iron chip 11); the first set of first positioning components at the lowest level is activated to position the second rotor iron chip 11 and drive it to rotate horizontally by 90 degrees; 5) When the third rotor iron chip 11 is horizontally supported on the second set of the first receiving layer, the layer seat 14 of the adjacent third set of the first receiving layer unfolds from the receiving groove 16 (the unfolded layer seat 14 is used to receive the fourth rotor iron chip 11 that has been punched out, and also to allow the spray valve 19 in the layer seat 14 to spray glue onto the upper surface of the third rotor iron chip 11, and the first quick-drying component continuously blows hot air onto the upper surface of the rotor iron chip 11); the second set of the first positioning components is activated to position the third rotor iron chip 11 and drive it to rotate 180 degrees; 6) When the fourth rotor iron chip 11 is horizontally supported on the third set of the first receiving layer, the layer seat 14 of the adjacent fourth set of the first receiving layer unfolds from the receiving groove 16 (the unfolded layer seat 14 is used to spray glue onto the upper surface of the fourth rotor iron chip 11 by the spray valve 19 inside the layer seat 14, and the first quick-drying component continuously blows hot air onto the upper surface of the rotor iron chip 11); the third set of the first positioning component is activated to position the fourth rotor iron chip 11 and drive it to rotate 270 degrees; 7) The first linear actuator 25 pushes the receiving plate 27 upward, so that the second rotor iron chip 11, the third rotor iron chip 11 and the fourth rotor iron chip 11 are stacked on the first rotor iron chip 11 in sequence; when the fourth rotor iron chip 11 rises to a predetermined height, the punch presses the fifth rotor iron chip 11, which has just been punched, onto and stacks it on the upper surface of the fourth rotor iron chip 11. The stacking tightness is improved by the upper and lower pressing force between the punch and the receiving plate 27. 8) Repeat steps 2)-7) until the predetermined number of rotor iron chips 11 are stacked to form the rotor iron core; 9) The second linear actuator 34 pushes the rotor core from the receiving plate 27 onto the conveyor 33 for transport.

[0049] The second unloading stacking component includes a second unloading receiving component, a second unloading stacking component 36, a second quick-drying component 37, and a second iron core transfer component 38. The second unloading receiving component is located inside the lower base 9 and receives the stator iron cores 12 under unloading. The second unloading stacking component 36 is located in the inner cavity of the base of the machine tool 5 and is correspondingly positioned directly below the second unloading receiving component to tightly stack multiple stator iron cores 12 within the second unloading receiving component. The second quick-drying component 37 is located on the lower base 9 and is used to blow hot air onto the upper surface of the stator iron cores 12 received in the second unloading receiving component to accelerate the curing of the adhesive. The second iron core transfer component 38 is located inside the lower base 9 and is used to transfer a predetermined number of rotor iron cores stacked on the second unloading stacking component 36 to the outside of the machine tool 5 as needed.

[0050] The second blanking receiving component includes a second support base 39, a second receiving layer component 40, a second adhesive dispensing component 41, and a second positioning component. The second support base 39 is disposed on the lower base 9 to provide support. The second receiving layer component 40 is disposed on the second support base 39 and is used to successively receive multiple stator iron chips 12 and to layer the multiple stator iron chips 12. The second adhesive dispensing component 41 is disposed on the second receiving layer component 40 and is used to spray adhesive onto the upper surface of the multiple stator iron chips 12. The inner wall of the second support base 39 is cylindrical, and the diameter of the inner wall of the second support base 39 is not less than the outer diameter of the stator iron chip 12. The top port of the second support base 39 is aligned with the cavity of the die 10 of the lower die base 8 so that the blanked stator iron chips 12 are pushed into the inner cavity of the second support base 39, and the stator iron chips 12 entering the inner cavity of the second support base 39 are horizontally received by the second receiving layer component 40.

[0051] The second receiving layer component 40 has the same structure as the first receiving layer component. The connection method between the second receiving layer component 40 and the second support base 39 is the same as the connection method between the first receiving layer component and the first support base 13. It is used to horizontally support the stator iron chip 12.

[0052] Furthermore, sixteen sets of the second receiving layer component 40 are provided. The sixteen sets of the second receiving layer component 40 are divided into four groups (each group has four sets of the second receiving layer component 40). The four groups of the second receiving layer component 40 are evenly distributed along the axial direction of the second receiving seat, and the four sets of the second receiving layer component 40 in each group are evenly distributed along the horizontal circumferential direction of the second receiving seat (the four sets of the second receiving layer component 40 in each group are used to simultaneously receive one of the stator iron chips 12).

[0053] The second dispensing component 41 has the same structure as the first dispensing component. The connection method between the second dispensing component 41 and the second receiving layer component 40 is the same as the connection method between the first dispensing component and the first receiving layer component. It is used to spray adhesive onto the upper surface of the stator chip 12 held on the second receiving layer component 40. It should be noted that the second dispensing component 41 within the lowest group of second receiving layer components 40 is used to spray adhesive onto the upper surface of the stator chip 12 on the second unloading stack component 36.

[0054] The second positioning component includes a second circumferential rotating component 42 and a second circumferential positioning component. The second circumferential rotating component 42 is on the first support base 13 and can drive the connected second circumferential rotating component 42 to rotate circumferentially. The second circumferential positioning component positions the rotor iron chip 11 circumferentially on the second circumferential rotating component 42 and drives the rotor iron chip 11 to rotate circumferentially by a multiple of 90 degrees.

[0055] The second circumferential rotating component 42 has the same structure as the first circumferential rotating component, and the connection method between the second circumferential rotating component 42 and the second support base 39 is the same as the connection method between the first circumferential rotating component and the first support base 13. The second circumferential positioning component includes a transmission block and a positioning plate 43. One end of the transmission block is horizontally fixed on the circumferential rotating ring 20 of the second circumferential rotating component 42. The transmission block is generally arc-shaped, and the outer arc surface of the transmission block is fixed on the other end of the transmission block. The bottom surface height of the transmission block is not less than the top surface height of the layering base 14 of the second receiving layering component 40, so that the transmission block can drive the stator iron chip 12 to rotate on the top surface of the layering base 14. Furthermore, the axial projection dimension of the positioning plate 43 is the same as the groove dimension on the outer ring of the stator iron chip 12. Alternatively, the top corner of the positioning plate 43 is chamfered to facilitate the movement of the stator chip 12 from top to bottom within the first support base 13 tube. The groove on the outer ring of the stator chip 12 can be slidably fitted onto the positioning plate 43, which facilitates the adjustment of the accuracy of the stator chip 12 before stacking.

[0056] It should be noted that after the second circumferential positioning component drives the stator core 12 to rotate at equal angles and then stacks them together, it can reduce the thickness unevenness error and flatness error of the stator core 12, thereby effectively improving the thickness uniformity of the stacked stator core and reducing the total height error of the stator core.

[0057] The second positioning component is provided in three sets, and the three sets of the second positioning component are equally spaced along the axial direction of the second support base 39, so as to position and rotate the stator iron chip 12 supported on the second receiving layer 40 below.

[0058] The second material dropping stack member 36 has the same structure as the first material dropping stack member, and the correspondence between the second material dropping stack member 36 and the second material dropping receiving member is the same as the correspondence between the first material dropping stack member and the first material dropping receiving member, for automatically stacking multiple stator iron chips 12 upwards.

[0059] The second quick-drying component 37 has the same structure as the first quick-drying component. The connection method between the second quick-drying component 37 and the second support base 39 is the same as the connection method between the first quick-drying component and the first support base 13, and the function of the second quick-drying component 37 is the same as that of the first quick-drying component. The second core transfer component 38 has the same structure as the first core transfer component and is used to transfer a predetermined number of stacked stator core wafers 12 outwards. The usage method of the second unloading and stacking component is the same as that of the first unloading and stacking component. This system is suitable for the production of stator and rotor cores for large motors.
