Description

Technical Field

[0001] This invention relates to the field of lamination equipment technology, specifically to a lamination equipment for processing rotor laminations of new energy vehicle motors. Background Technology

[0002] As is well known, the drive motor of a new energy vehicle is one of the core components of a new energy vehicle. It can realize the conversion between electrical energy and mechanical energy, drive the vehicle and support the recovery of braking energy. The motor rotor is the rotating part of the motor that outputs torque. It can generate torque under the action of a rotating magnetic field and output rotational power. The main structure is made of silicon steel sheets stacked together. In order to facilitate the stacking manufacturing of silicon steel sheets, this solution forms a stacking device for processing stamping of motor rotor laminations for new energy vehicles.

[0003] A search revealed that Chinese patent application number CN202322051439.4 discloses a tooling for facilitating the stacking of motor magnetic pole laminations. The tooling is broadly described as including support legs for mounting on a motor magnetic pole lamination stacking device, and a support plate fixedly connected to the support legs. The support plate is square, with two support columns fixedly connected at symmetrical corners on its upper part. Through the coordinated arrangement of a pressing assembly and two clamping assemblies, the tooling achieves the effects of longitudinal pressing (stacking) and lateral clamping of the motor magnetic pole laminations. In use, the output shaft of the pressing cylinder extends longitudinally to press and fix the motor magnetic pole laminations. Simultaneously, as the output shaft of the pressing cylinder extends, it drives the two pressing assemblies to approach the motor magnetic pole laminations and clamp them laterally, achieving synchronous linkage between the pressing assembly and the clamping assembly.

[0004] Although the aforementioned existing technical solutions can be used to perform stacking operations with motor magnetic pole laminations, the stacking operation requires the silicon steel sheets to be stacked and arranged before they can be stored inside the laminations. This makes them highly dependent on manual labor or other equipment, and their overall functionality and practicality need to be further enhanced. Summary of the Invention

[0022] It should be further explained that the indexing assembly includes a support frame 8, on which a rotating frame 9 is mounted.

The inner support structure is used for supporting and positioning the stacked sheet 1. A top support frame 10 is fixedly connected to the support frame 8. A glue storage box 11 is installed on the top support frame 10. The bottom end of the glue storage box 11 is connected to a glue distribution box 13 via a connecting pipe 12. The inner support frame 9 is rotatably connected to a rubber roller 14. A first servo motor 15 and a second servo motor 16 are respectively installed on the outer side of the rubber box 13 and the support frame 8. The first servo motor 15 drives the rotation of the rubber roller 14, and the second servo motor 16 drives the rotation of the rotating frame 9. The rubber box 13 is installed on the outer side of the top support frame 10 via a lifting linkage structure. An annular groove is provided on the outer frame 27, and a transfer ring 33 rotatably engages within the annular groove. A transfer cylinder 34 is fixedly connected to the transfer ring 33, and a hinge ear 35 is fixedly connected to the transfer cylinder 34. Multiple inner support frames 31 are hinged to the hinge ear 35. A third servo motor 32... A drive gear 36 is installed on the actuating shaft. The drive gear 36 meshes with a transmission gear ring 37. The transmission gear ring 37 is fixedly connected to the outside of the transfer ring 33. Multiple pressing ears 38 are fixedly connected to the outside of the transfer cylinder 34. Each pressing ear 38 is fitted with a clamping bolt 39. Each clamping bolt 39 is threadedly connected to the transfer ring 33. An assembly plate 40 is fixedly connected to the outside of the outer frame 27. The assembly plate 40 is used for clamping and limiting the transfer ring 33. Through the design of the indexing component, it can be adapted to the rotor lamination of new energy vehicle motors to complete the auxiliary clamping and transfer of the lamination, which facilitates the indexing and gluing operations of the lamination.

[0023] Furthermore, the lifting linkage structure includes a lifting sleeve 41 and an electric control lever 42. The lifting sleeve 41 is fitted onto the top bracket 10, and the electric control lever 42 is installed at the top of the top bracket 10. The electric control lever 42 is used for height adjustment of the lifting sleeve 41. A rotating rod 43 is rotatably connected to the outside of the lifting sleeve 41. The rotating rod 43 is fixedly connected to the adhesive box 13. A flipping drive mechanism is installed between the rotating rod 43 and the top bracket 10. The flipping drive mechanism is used for linkage flipping during the lifting and adjusting process of the adhesive box 13. The flipping drive mechanism includes a guide fixing sleeve 44 and a flipping gear 45. The guide sleeve 44 is fixedly connected to the top bracket 10. A tension spring 46 is fixedly connected inside the guide sleeve 44. A linkage rack 47 is fixedly connected to the bottom end of the tension spring 46.

The straight tube 51 is connected to the glue storage tank 11, and the sealing shaft 50 is inserted into the straight tube 51. When the lifting sleeve 41... When the height decreases, the adhesive box 13 flips and adjusts to the position where the adhesive roller 14 faces downwards. At this time, the sealing shaft 50 falls relative to the straight tube 51 to create a connection between the straight tube 51 and the connecting pipe 12. Conversely, when the height of the lifting sleeve 41 increases, the adhesive box 13 flips and adjusts to the position where the adhesive roller 14 faces upwards, so that the adhesive on the adhesive roller 14 and inside the adhesive box 13 are both kept inside the adhesive box 13, reducing accidental dripping of adhesive. At the same time, the sealing shaft 50 is further inserted relative to the straight tube 51 to seal the connection between the straight tube 51 and the connecting pipe 12. An arc-shaped strip is provided on the inner lining ring 48. A linkage rod 53 is inserted into the arc-shaped opening 52. The linkage rod 53 is fixedly connected to the outside of the lifting sleeve 41 and limits the rotation of the rotating rod 43, ensuring that the rotating rod 43 can form an upright and inverted posture after raising and lowering. The lifting sleeve 41 has a pin hole 54, into which a connecting pin 55 is inserted. The actuator of the electric control rod 42 is fixedly connected to an insertion rod 56. The insertion rod 56 has a through hole that matches the connecting pin 55, forming a transmission connection between the electric control rod 42 and the lifting sleeve 41, which facilitates assembly and manufacturing.

[0024] In this embodiment, the electric lifting rod 5, the first servo motor 15, the second servo motor 16, the electric adjusting rod 18, the electric clamping rod 20, the electric synchronizing rod 28, the third servo motor 32, and the electric control rod 42 are all commercially available conventional devices known to those skilled in the art. In this invention, we are simply using them without modifying their structure or function. Their setting method, installation method, and electrical connection method can be easily understood by those skilled in the art by following the instructions for use, and will not be described in detail here.

[0025] In summary, the working process of this stacking device for processing rotor laminations of new energy vehicle motors is as follows: Before use, the stacking device is first aligned with the corresponding stamping equipment to ensure that multiple inner support structures can sequentially pass through the falling station of the rotor laminations of the new energy vehicle motors, forming inner support positioning for the rotor laminations. This facilitates the auxiliary conveying of the stacked laminations 1. Then, the electric lifting rod 5, the first servo motor 15, the second servo motor 16, the electric adjusting rod 18, the electric clamping rod 20, the electric synchronizing rod 28, the third servo motor 32, and the electric control rod 42 are electrically installed. After electrical installation, operation and debugging are performed. After debugging, the device can be put into stacking operation. During operation, the second servo motor 16 first drives the rotating frame 9 to rotate relative to the support frame 8, causing one group of inner support structures to rotate with the rotating frame. The 9th rotation is positioned directly below the dropping position of the stacked sheet 1, and the electric synchronous rod 28 in the inner support structure is activated. Its actuator extends outward and pushes the drive frame 29 to rise along the axis of the rotating cylinder 34. The rise of the drive frame 29 synchronously drives the displacement of multiple linkage frames 30, converting the axial thrust into radial thrust, driving multiple inner support frames 31 to expand outward synchronously. Since multiple inner support frames 31 are all connected to the hinge ear 35, the inner support frame 31 will rotate relative to the hinge ear 35 during the outward expansion process. That is, the top of the inner support frame 31 swings inward and the bottom of the inner support frame 31 swings outward, presenting a structure that is smaller at the top and larger at the bottom. After the stamping equipment drops the single stacked sheet 1 into place, the structure that is smaller at the top and larger at the bottom will press against the central hole wall of the stacked sheet 1 from the inside out, completing the inner support positioning of the single stamped sheet. Then, the second servo motor 16 drives the rotating frame 9 to rotate again, so that the stacked sheet 1 positioned by the inner support is rotated to the glue application position along with the inner support structure.

[0026] Meanwhile, the actuator of the electric control lever 42 drives the lifting sleeve 41 to slide down the top bracket 10 through the pin engagement of the insertion rod 56 and the connecting pin 55. During the downward movement of the lifting sleeve 41, the transfer rod 43 and the adhesive box 13 move down synchronously. When the transfer rod 43 moves down, the inner lining ring 48 on its outer wall moves down accordingly. Since the linkage rack 47 meshes with the tilting gear 45 and the linkage rack 47 is subjected to the action of the tension spring 46, when the tension on the linkage rack 47 cannot drive the tension spring 46 to stretch, the linkage rack 47 will form a relatively stable position relative to the guide fixing sleeve 44, that is, to drive the tilting gear 45 to rotate. During this process, since the tilting gear 45 is not subject to rotation limit, the tension spring 46 is only stretched slightly. As the tilting gear 45 rotates, when the linkage rod 53 rotates to the limit position within the arc-shaped slot 52, the transfer rod 43 will not move further. With each rotation, the transfer rod 43 rotates the adhesive box 13 from an inverted storage position to a working position with the adhesive roller 14 facing downwards. As the lifting sleeve 41 slides further down along the top support 10, the flipping gear 45 maintains its existing state and drives the linkage rack 47 to fall further. During this process, the adhesive roller 14 can be height-adapted relative to the stacking sheet 1 to ensure that the adhesive roller 14 can perform adhesive application on the stacking sheet 1. The adhesive roller 14 adopts a structure with an inner roller core and an outer soft cylindrical layer. On the one hand, it can temporarily store and absorb the adhesive entering from the connecting pipe 12. On the other hand, when the roller surface of the adhesive roller 14 contacts the stacking sheet 1, it can be compressed and deformed to facilitate the extrusion of the adhesive. When the stacking sheet 1 is slightly tilted, the soft layer on the outside of the adhesive roller 14 can also be adapted and finely adjusted with the tilted stacking sheet 1 to improve the matching between the two.

[0027] As the reversing gear 45 maintains its current state and drives the linkage rack 47 to fall further, the tension spring 46 will be stretched. The extended plate 49, which is fixed to the linkage rack 47, will drive the closed shaft 50 to move downward relative to the straight tube 51, restoring the connection between the straight tube 51, which was originally blocked by the closed shaft 50, and the connecting pipe 12. Under the action of gravity, the adhesive in the glue storage tank 11 flows into the glue distribution box 13 through the connecting pipe 12 and wets the glue distribution roller 14. The first servo motor 15 then runs and drives the glue distribution roller 14 to rotate at a uniform speed. The adhesive is evenly applied to the surface of the adhesive roller 14. The third servo motor 32 engages with the transmission gear ring 37 via the drive gear 36 on its actuation shaft, causing the transmission gear ring 37 to drive the transfer ring 33 to rotate within the annular groove. The transfer ring 33 then drives multiple inner support frames 31 to rotate synchronously via the transfer cylinder 34. Ultimately, this causes the stacked sheets 1 supported by the multiple inner support frames 31 to rotate synchronously around their own axes, enabling the adhesive roller 14 to complete the adhesive application to the entire end face of the stacked sheets 1. After the adhesive application is completed, the electric control lever 42 reverses its movement to drive the roller 14 to rotate. As the lowering sleeve 41 moves upward, the adhesive box 13, in conjunction with the linkage rod 53 and the arc-shaped slot 52, flips back to its original position with the adhesive roller 14 facing upward. Simultaneously, the sealing shaft 50 re-inserts into the straight tube 51 to cut off the adhesive path, preventing further dripping. The second servo motor 16 drives the rotating frame 9 to continue its indexing rotation, transferring the coated stacked sheet 1 to the stacking position directly above the pressing assembly. Due to the meshing transmission relationship between the drive gear 26 and the transmission gear 25, during the rotation of the rotating frame 9, the drive gear 26 will... The drive gear 25 is rotated, ultimately causing the rotating shaft 24 to rotate. By setting the specifications of the drive gear 26 and the drive gear 25, the stacked sheet 1 is transported to the stacking position directly above the pressing assembly, where it enters the inverted state. To prevent the inverted stacked sheet 1 from falling relative to the multiple inner supports 31, the electric synchronizing rod 28 should be used during the flipping process to cause the inner supports 31, which were originally swinging inward, to swing outward, and vice versa, thus entering the attached position. Figure 17 As shown in the diagram, in this state, the laminate 1 will not fall off after being flipped.

[0028] Upon reaching the stacking position, the electric adjusting rod 18 operates, driving the lifting frame 17 to rise along the inner wall of the support base 2 via a hinged transmission. This reduces the descent height of the stacked sheet 1 as it enters the lifting frame 17, preventing sheet misalignment or adhesive layer displacement due to excessive drop. The electric synchronizing rod 28 then rotates the end of the inner support frame 31 inward to retract it, disabling its limiting effect on the stacked sheet 1. Under its own weight, the stacked sheet 1 gradually falls into the lifting frame 17 as the outward swing amplitude of the inner support frame 31 decreases. The electric clamping rod 20 within the lifting frame 17 then actuates, its actuator pulling the synchronizing frame 21 downward. The synchronizing frame 21, in turn, drives multiple circumferentially distributed clamping frames 19 synchronously upward via multiple transmission rods 22. The stacked sheets 1 are radially centered and clamped from the outside as they fall into place. It should be noted that the first stacked sheet 1 placed into the lifting frame 17 does not require adhesive application, but all other stacked sheets 1 must be adhesive applied. The rotating frame 9 then continues to operate, repeating the cycle of sheet picking, adhesive application, rotation, and dropping. After stacking is completed, the electric lifting rod 5 actuates, and its actuator pushes the lifting frame 57 downwards. The transmission cylinders 58 at both ends of the lifting frame 57 slide downwards along the outer walls of the two vertical columns 3. The two rotating sleeves 6 descend synchronously with the transmission cylinders 58. The first pin 59 and the second pin 60 on the rotating sleeves 6 are respectively embedded into the first and second tracks on the vertical columns 3. The first pin 59 and the second pin 60 first move upwards along their respective insertion guides. The groove 61 descends vertically, causing the two pressing frames 7 to descend with the countersleeve 6 to a height close to the upper surface of the laminated laminations 1. Then, the first pin 59 and the second pin 60 enter the corresponding spiral guide groove 62. Guided by the spiral guide groove 62, the countersleeve 6 rotates circumferentially relative to the transmission cylinder 58, thereby driving the two pressing frames 7 to simultaneously rotate from the outside of the laminated laminations 1 into its upper part. Finally, the first pin 59 and the second pin 60 enter the pressing guide groove 63 and descend vertically again. The countersleeve 6 no longer rotates but only presses down in a straight line. The two pressing frames 7 then press the entire rotor laminations from top to bottom with their end faces touching, ensuring that the glued laminations are tightly bonded under pressure, while also ensuring the glue layer is evenly spread. After holding the pressure for a predetermined time, the rotor is complete. After the iron core is stacked and formed, the electric lifting rod 5 reverses its movement, driving the lifting frame 57 and the two transmission cylinders 58 to move upwards synchronously. The two counter-rotating sleeves 6 first rise vertically to disengage the pressing frame 7 from the lamination stack, and then rotate in the opposite direction through the spiral guide groove 62 to rotate and move the pressing frame 7 away. Finally, it returns to the initial height along the upward guide groove 61. At the same time, the electric clamping rod 20 retracts its actuator, and through the synchronous frame 21 and the transmission rod 22, it reverses its transmission to release the multiple clamping frames 19 outwards, releasing the clamping on the outer periphery of the rotor iron core formed by pressing multiple stacked laminations 1. The actuator of the electric adjusting rod 18 extends outwards to push the lifting round frame 17 to rise along the support base 2, lifting the stacked rotor iron core to a height that is easy to remove. The operator or the matching robot can then remove the finished rotor iron core.Furthermore, the material handling operation can also be achieved through the relative insertion and outward swinging of multiple inner support frames 31. The device then resets and enters the next stacking cycle. This embodiment demonstrates single-sided adhesive application of the stacked sheet 1. In practical applications, the number of adhesive rollers can be selectively increased according to the specific needs of the stacked sheet 1 to achieve double-sided adhesive application of the stacked sheet 1.
