Description

Technical Field

[0001] This invention belongs to the field of stator and rotor lamination stamping technology, specifically a fully automatic stator and rotor lamination stamping system. Background Technology

[0002] As core components of electromagnetic induction equipment such as motors and generators, stator and rotor laminations directly determine the energy conversion efficiency, operational stability, and manufacturing cost of the terminal equipment due to their structural precision, dimensional consistency, and production efficiency. With the rapid development of new energy vehicles, industrial automation, smart grids, and other fields, the market demand for stator and rotor laminations has exploded, while also placing more stringent requirements on their product precision, material utilization rate, and mass production stability.

[0003] Publication No. CN118455360B discloses an automatic stamping equipment for stator and rotor laminations of water-cooled motors, including a stamping table and a discharge port on the front of the stamping table. An intermittent feeding mechanism is installed on the left side of the stamping table, and an upper stamping mechanism is installed on the top of the stamping table to perform stamping of silicon steel sheets from small to large levels along the direction of silicon steel sheet passage. A lower stamping mechanism that cooperates with the upper stamping mechanism is movably installed inside the discharge port. A drive mechanism is installed on the rear side of the stamping table. The equipment produces stator and rotor laminations by stamping stator and rotor laminations of different sizes together. It can simultaneously produce one rotor lamination and two stator rings of different sizes. The two stator rings of different sizes can be used in motors of different sizes, which improves production efficiency and avoids waste of silicon steel sheets between stator and rotor laminations.

[0004] This device can simultaneously produce one rotor lamination and two stator rings of different sizes, thereby improving production efficiency. However, when recycling the stator and rotor laminations, the device only uses a set of guide slides for guidance and recycling, which cannot ensure that the stator and rotor laminations are stacked in an orderly and efficient manner inside the recycling rack. The use of scattered stator and rotor laminations is too cumbersome when they are subsequently retrieved for use. Therefore, a fully automatic stamping system for stator and rotor laminations is proposed. By orderly stacking and recycling the stamped stator and rotor laminations, the efficiency of subsequent stator and rotor lamination loading is improved. Summary of the Invention

[0008] Preferably, two sets of the first cylinder and the extension frame are provided, and the first cylinder and the extension frame are symmetrically distributed about the central axis of the mounting cylinder. The outer wall of the pressing block is attached to the inner wall of the extension box. Two sets of the first return spring are provided, and the first return spring is symmetrically distributed about the central axis of the pressing block. The first return spring is used to squeeze the pressing block and keep it moving upward.

[0009] Preferably, the first transmission rod is externally engaged with a meshing belt, the meshing belt is internally engaged with a second transmission rod, a baffle is fixed to the top of the receiving frame, a first gear is fixed to the outside of the first transmission rod, a second gear is meshed to the top of the first gear, a third transmission rod is fixed to one end of the second gear, and a pressure cylinder is fixed to the outside of the third transmission rod.

[0010] Preferably, the second transmission rod and the receiving frame are rotatably connected, and two sets of baffles are provided, which are symmetrically distributed about the central axis of the receiving frame.

[0011] Preferably, the recycling mechanism includes a support base, a second cylinder, and a receiving tray. The support base is located at the bottom of the receiving rack, the second cylinder is fixed to the top of the support base, the receiving tray is fixed to the top of the second cylinder, and a positioning rod is fixed to the top of the support base.

[0012] Preferably, the support base is provided in several groups, the second cylinder is provided in four groups, the second cylinder is distributed in a circular array about the central axis of the support base, and the outer diameter of the positioning rod is equal to the inner diameter of the stator and rotor laminations.

[0013] Preferably, the limiting mechanism includes a second return spring, a pressure rod, and a trigger block. The second return spring is fixed inside the receiving frame, and a pressure rod is fixed outside the second return spring. The trigger block is slidably connected inside the support base, and a discharge rod is fixed outside the trigger block. A third return spring is fixed outside the trigger block, and a discharge block is fixed outside the receiving tray.

[0014] Preferably, there are two sets of the second return spring and the pressure rod, which are symmetrically distributed about the central axis of the receiving frame. The second return spring is used to squeeze the pressure rod and keep it moving towards the central axis of the receiving frame. The pressure rod has an arc surface on its outer side, and the support base has an arc surface on its outer side.

[0015] Preferably, the outer wall of the trigger block fits against the inner wall of the support base. Two sets of trigger blocks and unloading rods are provided, symmetrically distributed about the central axis of the support base. The third return spring is used to compress the trigger blocks and unloading rods, maintaining their tendency to move towards the central axis of the support base. The top end of the trigger block and the bottom end of the unloading block are both arc-shaped. Compared with the prior art, the beneficial effects of the present invention are as follows: This invention, through the coordinated arrangement of a discharge rack, a second electromagnet, and a first servo motor, enables the device to achieve stable transmission and shaping of the stamped stator and rotor laminations, ensuring lamination quality. The second electromagnet attracts the stamped laminations and precisely lowers them onto the meshing belt. The first servo motor drives the first transmission rod to move the meshing belt to transport the laminations. Simultaneously, the first gear links the second gear and the pressure cylinder to rotate, pressing and shaping the end laminations to prevent warping. Two sets of baffles limit lamination offset, ensuring stable and efficient transmission and shaping processes.

[0016] This invention, through the combination of a stepper motor, a mounting cylinder, and a first cylinder, enables the device to achieve fully automatic feeding and unloading of stator and rotor laminations, thereby improving production efficiency. The stepper motor drives the mounting cylinder to rotate intermittently by 90 degrees, and two sets of extension frames work alternately. The first cylinder drives the extension frame to move downward, and the electric suction cup picks up the raw material from the feeding frame and transfers it to the stamping machine. After stamping, the first electromagnet attracts the finished product for transfer. The first return spring and pulley in the extension box provide buffer for the extension frame, ensuring the stability of picking and placing.

[0017] This invention, through the coordinated use of a support base, a second cylinder, and a receiving tray, enables the device to achieve orderly stacking and recycling of stator and rotor laminations, improving subsequent loading efficiency. The positioning rod is inserted into the inner diameter of the lamination for precise positioning, the receiving tray receives the laminations, and the second cylinder gradually moves downward as the laminations stack, always maintaining the receiving tray and the laminations' falling position to prevent damage from falling laminations. Multiple sets of support bases can be used alternately to ensure continuous recycling.

[0018] This invention, through the combination of a second reset spring, a pressure rod, and a trigger block, enables the device to quickly position and replace the recycling mechanism, ensuring recycling continuity. When the support base slides to the recycling position, it squeezes the pressure rod, and the second reset spring pushes the pressure rod into the support base to complete the limit. After the stamping is stacked, the receiving tray moves down, causing the unloading block to squeeze the trigger block, and the unloading rod pushes the pressure rod to disengage, allowing the support base to be quickly removed and replaced with an empty base, reducing downtime.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] like Figures 1 to 10 As shown, the present invention provides a fully automatic stamping system for stator and rotor laminations, including a support base 1, a transmission mechanism 2 fixed at the top of the support base 1, a feeding rack 3 provided outside the support base 1, a stamping machine 4 installed outside the support base 1, a receiving rack 5 provided outside the support base 1, a discharging mechanism 6 fixed at the top of the receiving rack 5, a recycling mechanism 7 provided at one end of the receiving rack 5, and a limit mechanism 8 installed at one end of the recycling mechanism 7.

[0023] The above scheme is adopted as follows: the unprocessed stator and rotor laminations are stacked by the loading rack 3 and placed within the rotation diameter of the extension rack 204. The stator and rotor laminations are placed on the stamping machine 4 by the electric suction cup 209 and rotated to the next working path. The stamping machine 4 is started to stamp the stator and rotor laminations, and the stamped stator and rotor laminations are stuck at the lifting end of the stamping machine 4. When the first electromagnet 210 rotates and is located at the bottom of the processed stator and rotor laminations, the first electromagnet 210 is started to attract the stator and rotor laminations, so that they fall onto the first electromagnet 210 for transmission, and then unloaded.

[0024] like Figures 1 to 4As shown, the transmission mechanism 2 includes a stepper motor 201, a mounting cylinder 202, and a first cylinder 203. The stepper motor 201 is fixed to the bottom of the support base 1. The rotating end of the stepper motor 201 is fixed to the mounting cylinder 202. The bottom of the mounting cylinder 202 is fixed to the first cylinder 203. The extension end of the first cylinder 203 is fixed to the extension frame 204. An extension box 205 is fixed to the outside of the support base 1. The bottom of the extension box 205 is fixed to the first return spring 206. The top of the first return spring 206 is fixed to the pressing block 207. The first cylinder 203 and the extension frame 204 are... Two sets of cylinders are provided. The first cylinder 203 and the extension frame 204 are symmetrically distributed about the central axis of the mounting cylinder 202. The outer wall of the pressing block 207 is attached to the inner wall of the extension box 205. Two sets of first return springs 206 are provided. The first return springs 206 are symmetrically distributed about the central axis of the pressing block 207. The first return springs 206 are used to press the pressing block 207 and keep it moving upward. The pressing block 207 is rotatably connected to a pulley 208. The bottom end of the extension frame 204 is fixed with an electric suction cup 209, and the top end of the extension frame 204 is fixed with a first electromagnet 210.

[0025] The above scheme is adopted as follows: Stepper motor 201 is started to drive mounting cylinder 202 to rotate 90 degrees, ensuring that electric suction cup 209 and first electromagnet 210 are always positioned in four directions. When extension frame 204, electric suction cup 209, and first electromagnet 210 are at the top of loading rack 3, first cylinder 203 is started to drive extension frame 204 to move downwards as a whole. Electric suction cup 209 then picks up the stator and rotor laminations on loading rack 3. Simultaneously, extension frame 204 contacts pulley 208, and first return spring 206 and pressing block 207 buffer the extension frame 204 to ensure the stability of the suction. After suction is completed, stepper motor 201 is started to rotate extension frame 204 90 degrees, and then electric suction cup 209... When disc 209 is closed, the stator and rotor laminations are placed on the processing end of the press 4 and continue to rotate. At this time, the press 4 stamps the stator and rotor laminations. After stamping, the stamped stator and rotor laminations are stuck on the lifting end of the press 4 and lifted, so that the stamped stator and rotor laminations are located at the top of the next set of extension frames 204. At this time, the electric suction cup 209 is started to feed the stator and rotor laminations, and the first electromagnet 210 is started to attract the stator and rotor laminations processed at the top. After the stamped stator and rotor laminations are collected, when the first electromagnet 210 moves to the bottom of the second electromagnet 602, the first electromagnet 210 is closed and the second electromagnet 602 is started to attract the stator and rotor laminations to complete the suction.

[0026] like Figures 1 to 8As shown, the unloading mechanism 6 includes an unloading frame 601, a second electromagnet 602, and a first servo motor 603. The unloading frame 601 is fixed to the top of the receiving frame 5. The second electromagnet 602 is fixed to the top of the unloading frame 601. The first servo motor 603 is fixed to the outside of the receiving frame 5. A first transmission rod 604 is fixed to the rotating end of the first servo motor 603. A meshing belt 605 is externally engaged with the first transmission rod 604. A first servo motor 603 is internally engaged with the first transmission rod 604. The second transmission rod 606 and the receiving frame 5 are rotatably connected. Two sets of baffles 607 are provided, and the baffles 607 are symmetrically distributed about the central axis of the receiving frame 5. The first transmission rod 604 is fixed with a first gear 608. The top of the first gear 608 is meshed with a second gear 609. One end of the second gear 609 is fixed with a third transmission rod 610. The third transmission rod 610 is fixed with a pressure cylinder 611.

[0027] Using the above scheme: After the stamped stator and rotor laminations are attracted by the second electromagnet 602, the extension frame 204 continues to rotate. At this time, there is no obstruction below. The second electromagnet 602 is turned off, and the stator and rotor laminations are lowered so that they fall into the top of the meshing belt 605. The first servo motor 603 is started to drive the first transmission rod 604 to rotate, thereby driving the meshing belt 605 to move, and then driving the stator and rotor laminations to move. When the first transmission rod 604 rotates, it simultaneously drives the second gear 609, the third transmission rod 610 and the pressure cylinder 611 through the first gear 608 to rotate. Then, the stator and rotor laminations that have moved to the end are pressed by the pressure cylinder 611 and the first transmission rod 604 to prevent the stator and rotor laminations from warping and to fall into the positioning rod 704 for recycling.

[0028] like Figures 1 to 9 As shown, the recycling mechanism 7 includes a support base 701, a second cylinder 702, and a receiving tray 703. The support base 701 is located at the bottom inside the receiving rack 5. The second cylinder 702 is fixed to the top of the support base 701, and the receiving tray 703 is fixed to the top of the second cylinder 702. A positioning rod 704 is fixed to the top of the support base 701. The support base 701 is provided with several sets, and the second cylinder 702 is provided with four sets. The second cylinders 702 are arranged in a circular array about the central axis of the support base 701. The outer diameter of the positioning rod 704 is equal to the inner diameter of the stator and rotor laminations.

[0029] By adopting the above solution, the receiving plate 703 is raised by starting the second cylinder 702, so that the height of the receiving plate 703 is always at the height that the stator and rotor laminations can be quickly borne when they fall into the positioning rod 704, and then instantly lowered when it has borne a sufficient number of stator and rotor laminations.

[0030] like Figures 1 to 10As shown, the limiting mechanism 8 includes a second return spring 801, a pressure rod 802, and a trigger block 803. The second return spring 801 is fixed inside the receiving frame 5, and the pressure rod 802 is fixed outside the second return spring 801. The trigger block 803 is slidably connected inside the support base 701, and a discharge rod 804 is fixed outside the trigger block 803. A third return spring 805 is fixed outside the trigger block 803, and a discharge block 806 is fixed outside the receiving tray 703. Two sets of the second return spring 801 and pressure rod 802 are provided, and the second return spring 801 and pressure rod 802 are symmetrically distributed about the central axis of the receiving frame 5. 01 is used to press the pressure bar 802 and keep it moving towards the central axis of the receiving frame 5. The pressure bar 802 has an arc surface on its outer side, and the support base 701 has an arc surface on its outer side. The outer wall of the trigger block 803 is attached to the inner wall of the support base 701. There are two sets of trigger blocks 803 and unloading rods 804. The trigger blocks 803 and unloading rods 804 are symmetrically distributed about the central axis of the support base 701. The third return spring 805 is used to press the trigger block 803 and unloading rods 804 and keep them moving towards the central axis of the support base 701. The top of the trigger block 803 has an arc surface, and the bottom of the unloading block 806 has an arc surface.

[0031] The above scheme is adopted as follows: When the support base 701 slides towards the receiving rack 5 to the recycling position, the support base 701 contacts the arc surface of the pressure rod 802 through the arc surface and squeezes the pressure rod 802. After the pressure rod 802 retracts, the support base 701 continues to slide. When the slot of the support base 701 is aligned with the pressure rod 802, the restoring force of the second return spring 801 inserts the pressure rod 802 into the interior of the support base 701, thereby completing the limiting of the support base 701. This ensures that the position of the positioning rod 704 is at the recycling position. When the receiving tray 703 has recycled enough stator and rotor laminations and gradually lowers, the unloading block 806 moves downward and squeezes the two sets of trigger blocks 803. This causes the trigger blocks 803 to move outward and push the pressure rod 802, thereby pushing the pressure rod 802 out of the interior of the support base 701. At this time, the set of support bases 701 can be removed, and the next empty set of support bases 701 can be quickly installed by sliding, thereby ensuring the efficiency of recycling the processed stator and rotor laminations.
