Description

Technical Field

[0001] This application relates to the field of motor stator processing technology, and in particular to a motor stator lamination discharge device. Background Technology

[0002] An automotive alternator is an important component of a car, converting the mechanical energy of the vehicle into electrical energy to power the car's electrical equipment. The basic structure of an automotive alternator includes a housing, stator, rotor, rectifier, and end caps. The stator is typically made of stacked silicon steel sheets. These silicon steel sheets, also known as stator laminations, are formed by stamping sheet material using a punch press. The stamped stator laminations are ring-shaped, with inner grooves for inserting wires and outer grooves for positioning during lamination.

[0003] In existing technology, firstly, personnel take out the steel sheet to be stamped, place the steel sheet on the stamping platform, adjust its position, and start the stamping device to stamp the steel sheet to form the stamped laminations required for the stator. The laminations fall from the discharge port, hit the baffle, and then fall vertically into the collection box. Subsequently, personnel stack the laminations in the collection box together and place them in a suitable position. Common motor stator lamination discharge devices on the market have a connecting rod set directly below the stamping platform to make the laminations stack neatly on the connecting rod. The structure is simple and facilitates the stacking of laminations.

[0004] Regarding the aforementioned technologies, as processing time increases, the laminations will continuously fall and accumulate on the connecting rod, making it difficult for workers to quickly and safely retrieve them. Workers can only wait for the stamping device to stop working before they can remove the stator laminations. Whether stacking them manually or waiting for the stamping device to stop working before removing the stator laminations, it will increase the labor intensity of the workers. Summary of the Invention

[0005] To address the issue of increased labor intensity for workers, this application provides a device for discharging stator laminations from motors.

[0006] The stator lamination unloading device for motors provided in this application adopts the following technical solution: A stator lamination feeding device for motors includes a falling assembly, a conveying assembly, multiple adjusting assemblies, a receiving assembly, and a discharging assembly. The falling assembly includes multiple falling cylinders for the laminations to fall. Multiple falling holes are provided on the stamping platform along the length of the steel strip. Each falling cylinder corresponds to a falling hole. Both ends of each falling cylinder are open. One end of each falling cylinder is connected to a falling hole. The conveying direction of the conveying assembly is consistent with the distribution direction of the multiple falling cylinders. The multiple adjusting assemblies are distributed along the conveying direction of the conveying assembly. Each adjusting assembly is located at the bottom of the falling cylinders. Each adjusting assembly includes a fixed plate and four adjusting plates. The fixed plate is connected to the conveying assembly. The four adjusting plates are evenly distributed around the fixed plate. Each of the four adjusting plates is slidably connected to the fixed plate on either side that is closer to or further away from each other. The four adjusting plates form a placement area for the stator laminations. The receiving assembly is located at the bottom of the conveying assembly. The receiving assembly includes a receiving frame, a rotating cylinder, and at least one receiving component. The rotating cylinder is rotatably connected to the receiving frame, and its orientation is consistent with the conveying direction of the conveying assembly. The receiving component is connected to the outer wall of the rotating cylinder and corresponds to the four adjusting plates on which the punches are fixed. The receiving component is used to receive the stacked punches and move them to the discharge assembly. The discharge assembly is located on one side of the rotating cylinder and is used for discharging materials.

[0007] By adopting the above technical solution, the falling cylinder corresponds to the falling hole and the openings at both ends are connected, which facilitates the falling of the stamping pieces from the stamping platform; the conveying direction of the conveying component is consistent with the distribution direction of the falling cylinder, the adjusting component is distributed along the conveying direction of the conveying component and located at the bottom of the falling cylinder, and its four adjusting plates can slide on the fixed plate to form a placement area and adjust the position of the stator stamping pieces to achieve orderly stacking of the stamping pieces; the receiving component is located at the bottom of the conveying component, and the receiving component is connected to the rotating cylinder to receive the stacked stamping pieces; the discharge component is located on one side of the rotating cylinder, and the receiving component moves the stamping pieces to the discharge component for discharge, realizing the automation of stamping piece discharge, avoiding frequent manual operation, reducing the labor intensity of personnel, and improving the stamping piece discharge efficiency.

[0008] In one specific implementation, the receiving component includes a receiving plate and two stop bars. The receiving plate is connected to the outer wall of the rotating cylinder. When stacked punches need to be placed on the receiving plate, the receiving plate is located at the top of the rotating cylinder. The receiving plate is parallel to the conveying direction of the conveying assembly. The four adjusting plates with punches fixed thereon correspond to the receiving plate. Both stop bars are connected to the side of the receiving plate near the discharge assembly. The stop bars are perpendicular to the receiving plate and are spaced apart along the length of the side of the stop bar near the receiving plate. The discharge assembly includes a discharge frame, a discharge trough, and a pusher. The receiving frame and the discharge frame are distributed along the rotation direction of the rotating cylinder. The discharge trough is arranged from the receiving frame to the discharge frame, moving away from the discharge frame. The discharge trough is connected to the discharge frame. Both ends of the discharge trough, which is arranged in an inclined direction, are open. The pusher is slidably connected to the discharge trough along the arrangement direction of the discharge trough. The discharge trough has a clearance groove at the end near the receiving frame for the passage of the stop rod and the receiving plate. When the stop rod and the receiving plate are located in the clearance groove, the bottommost stamping overlaps with the pusher, and the pusher can push the stamping to move.

[0009] By adopting the above technical solution, the receiving plate can receive stacked stampings, the stop bar can block the stampings to prevent them from shifting during rotation; the inclined discharge chute facilitates the discharge of stampings, the pusher can push the stampings to slide along the discharge chute, and the clearance groove allows the stop bar and receiving plate to smoothly enter the discharge chute, allowing the bottom stampings to overlap with the pusher, thus realizing the smooth transfer and discharge of stampings from the receiving component to the discharge assembly.

[0010] In one specific implementation, the discharge assembly further includes two discharge components, each of which is connected to two opposite sidewalls of the discharge trough, and the discharge components are connected to the discharge trough. The pusher includes two L-shaped blocks with their openings facing each other. The discharge component is connected to each L-shaped block in a one-to-one correspondence. The two L-shaped blocks form a pushing area for stacked stampings. The stop bar and the receiving plate are located in the clearance groove. The stacked stampings are located in the pushing area, and the bottom of the lowest stamping overlaps with the side wall of the L-shaped block away from the discharge groove.

[0011] By adopting the above technical solution, the discharge component is connected to the discharge chute and correspondingly connected to the L-shaped block, which can drive the L-shaped block to slide along the discharge chute; the two L-shaped blocks form a pushing area. When the receiving plate and the stop bar are located in the clearance groove, the stacked stampings are located in the pushing area and the bottom of the bottom stampings overlaps on the L-shaped block, which facilitates the L-shaped block to push the stacked stampings to move along the discharge chute for discharge.

[0012] In one specific implementation, the stamping platform has three drop holes, and the number of drop cylinders is three. The conveying assembly includes a conveying frame, two conveying rollers, a conveyor belt, and a conveying component. The conveying frame is arranged along the distribution direction of the three drop cylinders, the two conveying rollers are distributed along the distribution direction of the three drop cylinders, the conveying rollers are arranged perpendicular to the axis of the drop cylinders, and the conveying rollers are arranged perpendicular to the distribution direction of the three drop cylinders. Both ends of the conveying rollers are rotatably connected to the conveying frame. The conveyor belt is wound around the two conveying rollers, and the conveying component is connected to the conveying frame. The conveying component is connected to the conveying rollers to drive the conveying rollers to rotate. The number of adjustment components is six, and the six adjustment components are divided into two groups. The two groups of adjustment components are located at the top and bottom of the conveyor belt, respectively. When three adjustment components in one group correspond one-to-one with the three falling cylinders, the other group of three adjustment components are located at the bottom of the conveyor belt. The number of receiving components is three, and the three receiving components are evenly distributed around the circumference of the rotating cylinder. The three receiving plates correspond one-to-one with the three adjustment components in each group. When it is necessary to place the stacked punches on the receiving plates, the receiving plates are located at the top of the rotating cylinder.

[0013] By adopting the above technical solution, the stamping platform has three drop holes and three drop cylinders, which can enable multiple stamping devices to simultaneously stamp multiple positions of the steel strip, thereby improving stamping efficiency. The conveyor frame, conveyor rollers, conveyor belt, and conveyor components of the conveying assembly work together to drive the conveyor belt and move the adjusting components. The six adjusting components are grouped and set at the top and bottom of the conveyor belt, which can realize the cyclical acceptance of stamped sheets and improve the stamped sheet acceptance efficiency. The three receiving components are evenly distributed along the circumference of the rotating cylinder and correspond to the adjusting components, which can cyclically accept the stacked stamped sheets, realize the continuous discharge of stamped sheets, and improve the discharge efficiency.

[0014] In one specific implementation, the adjusting assembly further includes adjusting components, each comprising four first screws, four first bevel gears, one second bevel gear, and an adjusting motor. Each adjusting plate has an adjusting groove near each adjusting plate on the side away from the conveyor belt. The adjusting grooves are arranged along the sliding direction of the adjusting plate. Each first screw corresponds to one of the adjusting grooves and is located within the adjusting groove. The first screw is rotatably connected to the fixing plate, and the adjusting plate is threadedly connected to the first screw. A placement groove is provided in the middle of the fixing plate, and one end of each first screw near the middle of the fixing plate extends into the placement groove. Each first bevel gear corresponds to one of the first screws and is coaxially connected to the end of each first screw located within the placement groove. The second bevel gear is located within the placement groove and meshes with the four first bevel gears. The second bevel gear is rotatably connected to the fixing plate. The adjusting motor is located near one of the first screws, and the housing of the adjusting motor is fixed to the fixing plate. The output shaft of the adjusting motor is coaxially fixed to the first screw via a coupling.

[0015] By adopting the above technical solution, the setting of the adjustment component enables the starting adjustment motor to drive the first screw to rotate. Since the adjustment plate is threadedly connected to the first screw, the four adjustment plates can slide back and forth along the length direction of the first screw, thereby realizing the adjustment of the position of the stator laminations in the placement area and making the laminations stacked more neatly.

[0016] In one specific implementation, the adjusting assembly further includes a guide member, which includes a guide plate, a threaded rod, and a guide cylinder. The guide plate is located at the opening of the placement slot and is connected to the fixed plate. The orientation of the guide plate is consistent with that of the fixed plate. The threaded rod is coaxially connected to the second bevel gear. The guide cylinder passes through the guide plate, and the top of the threaded rod is coaxially inserted into the guide cylinder. One end of the guide cylinder is threaded to the threaded rod. Two first guide rods are evenly connected circumferentially to the guide cylinder. The first guide rods are perpendicular to the axis of the guide cylinder. The guide plate has a receiving groove on the side away from the conveyor belt for accommodating the first guide rods.

[0017] By adopting the above technical solution, the rotation of the second bevel gear drives the rotation of the threaded rod, causing the guide cylinder to move along the length of the threaded rod towards the side away from the second bevel gear. The guide cylinder extends into the middle of the punch, and the first guide rod extends into the groove inside the punch to further limit the punch. When there is no punch in the placement area, the first guide rod is located in the receiving groove to ensure that the punch falls smoothly into the placement area.

[0018] In one specific implementation, the adjustment assembly further includes two blocking members, each corresponding to one of the two opposing adjustment plates. Each blocking member includes a blocking plate located in the placement area and passing through the sidewall of the adjustment plate. The two blocking plates are slidably connected to the adjustment plate towards or away from each other. When a certain number of stacked laminations are reached, the blocking plate is pushed, and the blocking plate contacts the lamination of the highest layer.

[0019] By adopting the above technical solution, the two blocking components in the adjustment assembly correspond to the two adjustment plates. When the stacked laminations reach a certain number, the blocking plates are pushed so that they contact the laminations on the top layer, which can further fix the laminations, making it easier for subsequent material discharge and the next process, and preventing the laminations from sliding out when the adjustment assembly with the fixed laminations moves to the bottom of the conveyor belt.

[0020] In one specific implementation scheme, the dropping cylinder is divided into a straight cylinder and a conical cylinder. The straight cylinder is coaxially arranged with the dropping hole and connected to the stamping platform. The shape of the straight cylinder is consistent with the shape of the stamping piece, and the diameter of the straight cylinder is slightly larger than the diameter of the stamping piece. The smaller end of the conical cylinder is connected to the end of the straight cylinder away from the stamping platform, and the larger end of the conical cylinder faces the placement area. The distance between the larger end of the conical cylinder and the top of the adjusting plate is small.

[0021] By adopting the above technical solution, the straight cylinder and the drop hole are coaxially arranged and the diameter is slightly larger than the diameter of the punch, which facilitates the punch falling in the straight cylinder; the smaller end of the conical cylinder is connected to the straight cylinder, and the larger end faces the placement area and has a small distance from the top of the adjustment plate, which facilitates the punch falling and can prevent the punch from colliding with the drop cylinder and tilting, ensuring that the punch falls smoothly into the placement area.

[0022] In one specific implementation, the area of ​​the receiving plate is smaller than the area of ​​the stamping sheet.

[0023] By adopting the above technical solution, when the receiving plate and the stop bar are located in the clearance groove, it is convenient for the bottom of the bottom punch to overlap with the side wall of the L-shaped block away from the discharge groove, which is conducive to placing the punch on the receiving plate in the pushing area.

[0024] In one specific implementation, each of the four adjustment plates is fixedly bonded with a flexible pad on one side close to each other.

[0025] By adopting the above technical solution, the four adjusting plates are fixedly bonded to one side, which can prevent the stator laminations from wearing when the adjusting plates adjust the stator laminations.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The designed motor stator lamination discharge device has a conveying component whose conveying direction is consistent with the distribution direction of the falling cylinder. The adjusting component is distributed along the conveying direction of the conveying component and located at the bottom of the falling cylinder. Its four adjusting plates can slide on the fixed plate to form a placement area and adjust the position of the stator laminations to achieve orderly stacking of the laminations. The receiving component is located at the bottom of the conveying component and is connected to the rotating cylinder to receive the stacked laminations. The discharge component is located on one side of the rotating cylinder. The receiving component moves the laminations to the discharge component for discharge, realizing the automation of lamination discharge, avoiding frequent manual operation, reducing the labor intensity of personnel, and improving the lamination discharge efficiency.

[0027] 2. The designed motor stator lamination discharge device has a receiving plate that can receive stacked laminations, a stop bar that can block the laminations to prevent them from shifting during rotation; the discharge chute is inclined to facilitate lamination discharge, the pusher can push the laminations to slide along the discharge chute, and the clearance groove allows the stop bar and receiving plate to smoothly enter the discharge chute, allowing the bottom laminations to overlap with the pusher, realizing the smooth transfer and discharge of laminations from the receiving component to the discharge assembly.

[0028] 3. The designed motor stator lamination discharge device has two blocking components in the adjustment assembly corresponding to two adjustment plates. When the stacked laminations reach a certain number, the blocking plates are pushed to make them contact the laminations on the top layer, which can further fix the laminations, making it easier to discharge and proceed to the next process. This prevents the laminations from sliding out when the adjustment assembly with the fixed laminations moves to the bottom of the conveyor belt. Attached Figure Description

[0038] Reference Figure 1The dropping assembly 1 includes multiple dropping cylinders 11. A pulling mechanism pulls the steel strip, causing it to slide onto the stamping platform to a suitable position for loading. Multiple stamping devices simultaneously stamp multiple positions of the steel strip. In this embodiment, there are three stamping devices, and three dropping holes are provided on the stamping platform. These three dropping holes are spaced apart along the length of the steel strip, with each stamping device corresponding to one of the dropping holes. There are also three dropping cylinders 11, each corresponding to one of the dropping holes. Each dropping cylinder 11 is divided into a straight cylinder 111 and a conical cylinder 112. The straight cylinder 111 is located at the bottom of the stamping platform. The straight cylinder 111 is coaxially arranged with the drop hole. The straight cylinder 111 is connected to the stamping platform by reinforcing bolts. The shape of the straight cylinder 111 is consistent with the shape of the stamping piece, and the diameter of the straight cylinder 111 is slightly larger than the diameter of the stamping piece, so that the stamping piece can fall inside the straight cylinder 111. The conical cylinder 112 is located at the end of the straight cylinder 111 away from the stamping. The smaller end of the conical cylinder 112 is connected to the bottom of the straight cylinder 111, and the straight cylinder 111 and the conical cylinder 112 are integrally connected. The larger end of the conical cylinder 112 faces the end away from the straight cylinder 111, so as to facilitate the falling of the stamping piece and prevent the stamping piece from colliding with the drop cylinder 11 and tilting.

[0039] Reference Figure 1 and Figure 2 The conveying assembly 2 includes a conveying frame 21, two conveying rollers 22, a conveyor belt 23, and a conveying component 24. The conveying frame 21 is located at the bottom of the conical cylinder 112 and is arranged along the distribution direction of the three falling cylinders 11. The conveying frame 21 is fixed to the ground by reinforcing bolts. The two conveying rollers 22 are distributed along the distribution direction of the three falling cylinders 11. The conveying rollers 22 are arranged perpendicular to the axis of the falling cylinders 11 and perpendicular to the distribution direction of the three falling cylinders 11.

All four plates 2 are slidably connected to the fixed plate 31. The four adjusting plates 32 move toward or away from each other, forming a placement area for the stator laminations. The four adjusting plates 32 can adjust the position of the stator laminations. Two of the opposing adjusting plates 32 are arc plates with their openings facing the central axis of the fixed plate 31. When the stator laminations are in the placement area, the arc plates can fit against the side walls of the stator laminations. The other two opposing adjusting plates 32 can be rectangular plates or arc plates, depending on the shape of the stator laminations. In this embodiment, the other two opposing adjusting plates 32 are rectangular plates, which can fit against the two planes facing the stator laminations. Flexible pads are fixedly bonded to the sides of the four adjusting plates 32 that are close to each other to prevent wear on the laminations. The larger end of the conical cylinder 112 and the top of the adjusting plate 32 are close together to ensure that the laminations fall smoothly into the placement area.

The barrier plate 331 is located in the placement area and is inserted through a designated position on the side wall of the rectangular plate. The specific position of the barrier plate 331 needs to be determined based on the number of laminations to be stacked for processing the stator. The barrier plate 331 is slidably connected to the rectangular plate. The two barrier plates 331 move towards or away from each other. When the number of stacked laminations reaches a certain amount, i.e., a certain height, the barrier is pushed. Plate 331, the barrier plate 331 contacts the highest layer of punches, which can further fix the punches and prevent the punches from sliding out when the adjusting component 3 with the fixed punches moves to the bottom of the conveyor belt 23. Then, it is discharged. The personnel only need to fix the stacked punches and proceed to the next process. The cylinder body of cylinder 332 is fixedly connected to the rectangular plate by screws.

The guide cylinder 353 and guide plate 351 have a receiving groove on the side away from the conveyor belt 23 for the first guide rod 3531 to be accommodated. When it is necessary to adjust the punches to make them stacked neatly, the adjustment motor 344 is started. The adjustment motor 344 drives the first screw 341 to rotate, which enables the four adjustment plates 32 to move and adjust the position of the punches. During this process, the second bevel gear 343 rotates, which can drive the threaded rod 352 to rotate. During the rotation of the threaded rod 352, the guide cylinder 353 can move along the length of the threaded rod 352 away from the second bevel gear 343. The guide cylinder 353 extends into the middle of the punch, and the first guide rod 3531 can extend into the groove inside the punch, which can further limit the punch.

The three receiving plates 441 correspond one-to-one with the three adjusting components 3 in each group. When it is necessary to place the stacked punches on the receiving plate 441, the receiving plate 441 is located at the top of the rotating cylinder 42, receiving the punches. Plate 441 is parallel to the conveying direction of conveyor belt 23 and is used to receive stacked punches. The discharge assembly 5 is located on one side of the rotating drum 42. When the stacked punches are on the receiving plate 441, the rotating drum 42 rotates, which causes the receiving plate 441 to rotate, allowing the stacked punches to be placed on the discharge assembly 5 for discharge. Both baffles 442 are located on the side of the receiving plate 441 near the discharge assembly 5. The baffles 442 are perpendicular to the receiving plate 441 and are spaced apart along the length of the side of the baffles 442 near the receiving plate 441. The stop lever 442 can block the laminations to prevent them from shifting during rotation. By writing the programmed instructions into the control system, the control system starts the conveyor 24, which drives the conveyor belt 23 to rotate, causing the adjusting assembly 3 with the laminations fixed to it to rotate. At this time, the adjusting assembly 3 without the laminations fixed to it moves synchronously with the conveyor belt 23 until the adjusting assembly 3 with the laminations fixed to it moves above the receiving plate 441. Then, the adjusting element 34 in the adjusting assembly 3 with the laminations fixed to it drives the four adjusting plates 32 to move away from each other. The side movement causes the stacked blanks to fall onto the receiving plate 441. The stop bar 442 blocks the blanks. When the blanks on the previous adjusting component 3 are placed on the receiving plate 441, the conveyor belt 23 drives the adjusting component 3 to move. At this time, the rotating cylinder 42 drives the receiving plate 441 that holds the blanks to move, so that the stacked blanks are placed on the discharge component 5. The next receiving plate 441 rotates synchronously, causing the next adjusting component 3 that holds the blanks to rotate, until the next adjusting component 3 that holds the blanks moves above the receiving plate 441 for the next discharge.

[0046] Reference Figure 4 and Figure 5The discharge assembly 5 includes a discharge frame 51, a discharge trough 52, two discharge components 53, and a pusher 54. The discharge frame 51 is located on one side of the rotating frame, and the rotating frame and discharge frame 51 are distributed along the rotation direction of the rotating cylinder 42. The discharge frame 51 is fixedly connected to the ground by reinforcing bolts. The discharge trough 52 is inclined and is inclined upward from the rotating frame to the discharge frame 51 towards the side away from the discharge frame 51. The discharge trough 52 is fixedly connected to the discharge frame 51 by screws. The two discharge components 53 are located on the two opposite side walls of the discharge trough 52. The discharge component 53 includes a second screw 531 and a discharge motor 532. Both ends of the discharge trough 52 are open along the inclined direction. The material trough 52 has a sliding groove 521 on each of its two opposite side walls, close to each other. The sliding grooves 521 are arranged along the setting direction of the discharge trough 52. Two second screws 531 are each located in one of the sliding grooves 521. The second screws 531 are arranged along the setting direction of the sliding grooves 521 and are rotatably connected to the discharge trough 52. The discharge motors 532 correspond one-to-one with the second screws 531. The housings of the discharge motors 532 are fixedly connected to the discharge trough 52 by screws. The output shaft of the discharge motor 532 is coaxially fixedly connected to the second screws 531 by a coupling. The discharge motors 532 drive the second screws 531 to rotate. The discharge motors 532 are all electrically connected to the control system.

[0047] Reference Figure 4 and Figure 5 The pusher 54 includes two L-shaped blocks 541, with their openings facing each other. Each L-shaped block 541 corresponds to a second screw 531 and is threadedly connected to it. The two L-shaped blocks 541 form a pushing area for stacked laminations. The discharge chute 52 near the rotating frame has a clearance groove 522 for the passage of a stop bar 442 and a receiving plate 441. The area of ​​the receiving plate 441 away from the rotating cylinder 42 is smaller than the area of ​​the lamination. When the receiving plate 441 and the stop bar 442 are located within the clearance groove 522, the bottom of the lamination at the bottom layer can easily overlap the L-shaped block 541 on the side away from the discharge chute 52. At one end of the wall, when it is necessary to place the punches on the receiving plate 441 into the pushing area, the control system starts the rotating motor 433, which drives the rotating cylinder 42 to rotate, so that the receiving plate 441 receiving the punches rotates towards the side closer to the discharge rack 51, so that the stop bar 442 and the receiving plate 441 are located in the clearance groove 522. At this time, the stacked punches are located in the pushing area, and the bottom of the punches at the bottom overlaps with the side wall of the L-shaped block 541 away from the discharge groove 52. At the same time, the two discharge motors 532 are started, which can make the second screw 531 rotate, so that the two L-shaped blocks 541 move synchronously, which can push the stacked punches to slide along the discharge groove 52 for personnel to pick up.

[0048] The implementation principle of the motor stator lamination unloading device in this application embodiment is as follows: When lamination unloading is required, firstly, the steel strip is slid to a suitable position on the stamping platform, the conveying component 2 is started in advance, and the adjusting component 3 is adjusted to a suitable position. The steel strip is stamped simultaneously by multiple stamping devices. The stamped laminations fall along the drop cylinder 11 to the placement area. During this process, the steel strip is pulled by the traction mechanism. When the number of laminations in the placement area reaches a preset value, the adjusting component 3 is started. The adjusting component 3 adjusts and limits the position of the laminations. Then, the conveying component 2 is started again, and the adjusting component 3 with the laminations fixed is moved to the receiving component 4. At this time, the adjusting component 3 without the laminations fixed moves to the bottom of the drop cylinder 11 and is stamped again, so that the laminations fall to the placement area, realizing the cyclic unloading. The receiving component 4 receives the stacked laminations and realizes the cyclic receiving by rotating. The unloading component 5 transports the laminations to the next process. This integrated design improves the unloading efficiency and quality of the laminations.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
