[0002] Due to the continuous rise in labor costs, the replacement of manual labor with mechanical equipment, automated production, reducing manpower and increasing efficiency, and intelligent production have become major trends in the manufacturing industry. At present, most motor lamination stacking processes still use the traditional manual stacking method, where people count the pieces, weigh them, stack them on the tooling, lock them, and then take them for welding or oven curing.

[0003] These products are typically produced in multiple batches, in small quantities, and in various models. There are over a dozen different types of stamped laminations, ranging in diameter from Φ20mm to Φ100mm. The laminations come in two structures: outer diameter with internal teeth and inner diameter with external teeth. Their thicknesses are only 0.2mm and 0.35mm, making them extremely prone to deformation. Due to these characteristics, manual stacking of these products results in poor product consistency.

[0049] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0050] Example 1

[0051] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 , Figure 8 , Figure 9 As shown, in this technical solution, the Y direction is the front-to-back direction, the X direction is the left-to-right direction, and the Z direction is the up-to-down direction. A dual-station stamping stacking device includes two feeding units 1, two stacking tooling units 2, two stacking units 5, a heating unit 6, and a pressing and tightening unit 7 arranged in parallel with the heating unit 6 in the Y direction. The feeding unit 1, the stacking tooling unit 2, and the stacking unit 5 located on the same side constitute a stacking station.

[0052] The feeding unit 1 includes a hollow rotating platform for placing the blanks; the stacking fixture unit 2 includes modules 201 distributed in the Y direction, the output end of which is connected to a base plate 202, and the stacking fixture is placed on the base plate 202; the stacking fixture is generally characterized by a disc at the bottom, a long shaft in the middle, and a nut that is threaded with the long shaft at the top; the stacking fixture corresponding to the stacking fixture unit 2 does not have a nut at the top.

[0053] The stacking unit 5 includes a base 501, on which a four-axis robot 502 is mounted, and the output end of the four-axis robot 502 is equipped with a vacuum nozzle 506; the heating unit 6 includes a heating coil 605.

[0054] The tightening unit 7 includes a tightening base plate 721, on which a module four 720 distributed in the Y direction is provided. The output end of the module four 720 is connected to a second adapter base plate 719. Stacked tooling is placed on the second adapter base plate 719. The upper end face of the tightening base plate 721 is connected to a tightening base plate 709 through a support column 707. A module three 714 distributed in the Z direction is provided on the tightening base plate 709. The output end of the module three 714 is connected to an electric screwdriver 713. A tightening sleeve 722 is provided at the output end of the electric screwdriver 713. A Z-direction moving pressure head 716 is provided between the tightening base plate 709 and the module four 720. The tightening sleeve 722 passes through the pressure head 716.

[0055] The stacking process of a dual-station stamping stacking device in this technical solution is as follows: 1. A worker places a stack of stampings on the hollow rotating platform in the feeding unit 1; 2. Module 1 201 moves forward, and the worker places the stacking fixture on the transfer base plate 1 202. Module 1 201 drives the stacking fixture to move backward to a predetermined position; 3. The four-axis robot 502 moves to the hollow rotating platform to pick up the stampings and stacks them onto the stacking fixture in the stacking fixture unit 2, stacking a predetermined number of stampings; 4. The stacked products are placed on the transfer base plate 2 719. Module 4 720 moves backward to transport the stacked product to the heating coil 605 for heating and curing; 5. After the product has been heated and cured, Module 4 720 moves forward to move the product under the pressure head 716. The pressure head 716 moves downward to apply a set pressure to the punch plate. Module 3 714 drives the electric screwdriver 713 to move downward. The output end of the electric screwdriver 713 drives the tightening sleeve 722 to rotate, applying a set torque to the nuts on the stacking fixture, locking the fixture, and recording the data to form quality traceability data. After completion, the worker removes the product.

[0056] In this technical solution of a dual-station stamping lamination stacking device, a feeding unit 1 is set up to continuously feed the stamping laminations, a stacking fixture unit 2 is set up to place the stacking fixture, a stacking unit 5 is set up to pick up the stamping laminations from the feeding unit 1 and move them to the stacking fixture unit 2 for stacking, a heating unit 6 is set up to heat and solidify the stacked products, and a tightening unit 7 is set up to apply a set pressure and torque to the solidified products to lock the stamping laminations. This dual-station stamping lamination stacking device realizes the automation of stamping lamination stacking, ensures the consistency of product stacking, and improves the stacking efficiency by setting up two stacking stations for stacking operations, thereby reducing manpower and increasing efficiency.

[0057] Specifically, to achieve continuous feeding of the sheet metal, such as Figure 1 , Figure 2 , Figure 3As shown, the hollow rotating platform includes a second motor 109, the output end of which is connected to a turntable 110. The turntable 110 is provided with a plurality of spindles 108. In this embodiment, four spindles 108 are provided.

[0058] The blanking sheet is manually mounted onto the blanking mandrel 108. Motor 2 109 drives the turntable 110 to rotate until the corresponding feeding mandrel 108 moves to the feeding station. The material picker (vacuum nozzle 2 506, vacuum nozzle 1 311) removes the blanking sheet from the feeding mandrel 108. The feeding mandrel 108 is manually replenished after feeding is completed. The feeding unit 1 is designed with four feeding stations and has the function of automatic switching feeding to realize continuous feeding of blanking sheets.

[0059] To ensure the stability of the position during the feeding of the sheet metal, such as Figure 1 , Figure 2 , Figure 3 As shown, the feeding unit 1 also includes a fixed-position rod upright plate 101 and a linear bearing 102. A lifting base plate 104 is provided at the lower end of the rod upright plate 101, and a motor 105 is provided on the lifting base plate 104. A guide column 103 passes through the linear bearing 102, and a lower lifting plate 106 is connected to the guide column 103. The output end of the motor 105 meshes with the lower lifting plate 106 and drives the lower lifting plate 106 to move in the Z direction.

[0060] Specifically, the output end of motor 105 is connected to a gear, and a longitudinally distributed rack is provided on the lower lifting plate 106. The gear meshes with the rack, and the forward or reverse rotation of motor 105, under the limiting action of linear bearing 102 and guide column 103, drives the lower lifting plate 106 to move in the Z direction through the meshing of the gear and rack.

[0061] The mandrel 108 is fitted with an upper lifting plate 107 that cooperates with the lower lifting plate 106. That is, the upper lifting plate 107 is set at the feeding station. When the motor 105 drives the lower lifting plate 106 to move upward, it pushes the upper lifting plate 107 to move upward simultaneously. The upper lifting plate 107 drives the punches to move upward, so that the upper ends of the punches at the feeding station are at the same height, ensuring that the punches to be picked up are in the same position and ensuring the stability of the feeding. When the motor 105 drives the lower lifting plate 106 to move downward, the upper lifting plate 107 moves downward to the initial position under the action of gravity.

[0062] To ensure the stability of material extraction, such as Figure 1 , Figure 2 , Figure 7 As shown, the output end of the four-axis robot 502 is connected to a nozzle base 503, and the nozzle base 503 is connected to a nozzle base plate 505 via an elastic element 504. A vacuum nozzle 506 is mounted on the nozzle base plate 505.

[0063] An elastic element 504 is installed between the output end of the four-axis robot 502 and the vacuum nozzle 506, so that when the vacuum nozzle 506 picks up the punch, the rigid contact with the punch becomes a flexible contact. The flexible contact reduces the possibility of damage to the punch and the vacuum nozzle 506, while ensuring stable contact between the vacuum nozzle 506 and the punch, thus ensuring stability during the material handling process.

[0064] The heating unit 6 is designed to heat and cure the stacked products. To improve the heating and curing effect, for example... Figure 1 , Figure 2 , Figure 8 As shown, the heating unit 6 includes a base 601 and a motor 603. A guide post 602 is provided on the base 601. The guide post 602 is fitted with a high-frequency machine base plate 608 through a linear bearing 607. A high-frequency machine 606 is provided on the high-frequency machine base plate 608. The heating coil 605 is assembled at the output end of the high-frequency machine 606. The high-frequency machine 606 provides high-frequency current to the heating coil 605.

[0065] The output end of motor 603 meshes with the high-frequency machine base plate 608, driving the high-frequency machine base plate 608 to move in the Z direction. Specifically, the output end of motor 603 is connected to a gear, and the high-frequency machine base plate 608 is provided with a longitudinally distributed rack. The gear meshes with the rack, and the forward or reverse rotation of motor 603, under the limiting action of guide post 602 and linear bearing 607, drives the high-frequency machine base plate 608 to move in the Z direction through the meshing of the gear and rack. Sensor fixing 604 is provided on the high-frequency machine base plate 608, and sensor 2 is provided on sensor fixing 604. The setting of sensor 2 is to detect whether the punch is in place.

[0066] In this technical solution, the heating unit 6 drives the heating coil 605 to move back and forth in the vertical direction by rotating the motor 603 in the forward or reverse direction. After the stacked product moves to the heating position (below the heating coil 605), the heating coil 605 moves downward until the product is inside the heating coil 605, and the product is heated for a specific time and at a specific temperature. The setting of the heating coil 605 covering the outside of the product improves the heating and curing effect, improves the heating uniformity of the heated product, and ensures product quality.

[0067] To achieve the setting requirement of Z-axis movement of the pressure head 716, such as Figure 1 , Figure 2 , Figure 9As shown, the lower end of the pressing base plate 721 is connected to the press fixing plate 702 via the column three 703. The press fixing plate 702 is equipped with a press 701. The press 701 can be configured as a component that drives the stretching plate 704 to move linearly, such as a cylinder. The cylinder drives the stretching plate 704 to move vertically by controlling the overall length. The output end of the press 701 is connected to the stretching plate 704. The stretching plate 704 is provided with a guide column three 706. The guide column three 706 passes through the pressing base plate 721 and is connected to the press head base plate 708. The guide column three 706 and the pressing base plate 721 are connected by a linear bearing three 705. The press head base plate 708 and the press head 716 are assembled through a pressure sensor 715. The pressure sensor 715 is set to detect the magnitude of the pressure applied to the product and ensure that the applied pressure is within the normal value.

[0068] In this technical solution, the press 701 is activated, causing the stretching plate 704 to move vertically. When the stretching plate 704 moves downward, the guide column 706 and the press head base plate 708 drive the press head 716 to move downward, applying pressure to the product in the press position (below the press head 716) and fixing the position of the punch. To improve the stability of the product during the pressing process, a pressure block 723 is set on the pressing base plate 721, and the adapter base plate 719 is placed on the pressure block 723 to support the product during the pressing process.

[0069] like Figure 1 , Figure 2 , Figure 6 As shown, a dual-station stamping stacking device also includes a positioning and imaging unit 4; the positioning and imaging unit 4 is set to identify the front and back of the stamping, identify whether the stamping has defects, and ensure the quality of the stacked products.

[0070] The positioning and imaging unit 4 includes an L-shaped upright plate 403, on which a hollow rotating wheel 406 is rotatably mounted. A transparent base plate 407 is mounted on the hollow rotating wheel 406, and a punch is placed on the transparent base plate 407. A motor 405 is mounted on one side of the L-shaped upright plate 403, and the output end of the motor 405 meshes with the hollow rotating wheel 406. Specifically, the output end of the motor 405 is equipped with a gear, and the hollow rotating wheel 406 has teeth. The gear meshes with the teeth, and the motor 405 is energized to start and drive the hollow rotating wheel 406 to rotate. The positioning and imaging unit 4 also includes a camera 402, which is mounted on a camera base plate 401. The camera base plate 401 is connected to the L-shaped upright plate 403 through a camera upright plate 404.

[0071] After the blanking sheet is removed from the feeding unit 1 by the material picker (vacuum nozzle 1 311, vacuum nozzle 2 506), it is placed on the transparent base plate 407. The camera 402 takes pictures of the blanking sheet for identification, including the angle, front and back of the blanking sheet. During the identification process, the hollow rotating wheel 406 can be rotated by the motor 3 405 to adjust the stacking angle of the blanking sheet. At the same time, the blanking sheet can be photographed from multiple angles to ensure the identification effect.

[0072] like Figure 1 , Figure 2 , Figure 5 As shown, a dual-station stamping stacking device also includes a transfer unit 3. The transfer unit 3 replaces the stacking unit 5, which takes material from the feeding unit 1 and places it at the position of the positioning and photographing unit 4. The transfer unit 3 takes material from the feeding unit 1 and places it at the position of the positioning and photographing unit 4. The stacking unit 5 places the stamping at the position of the positioning and photographing unit 4 at the stacking tooling unit 2, ensuring the continuity of the stacking process.

[0073] The transfer unit 3 includes a module 305 arranged in the Y direction. The output end of the module 305 is provided with an upper and lower cylinder 307. The output end of the upper and lower cylinder 307 is provided with a suction nozzle bracket 308. The suction nozzle bracket 308 is provided with a suction nozzle base plate 310 through an elastic element 309. A vacuum suction nozzle 311 is mounted on the suction nozzle base plate 310. The elastic element 309 is provided between the output end of the upper and lower cylinder 307 and the vacuum suction nozzle 311, so that when the vacuum suction nozzle 311 picks up the punch, the rigid contact with the punch becomes a flexible contact. The flexible contact reduces the possibility of damage to the punch and the vacuum suction nozzle 311, while ensuring stable contact between the vacuum suction nozzle 311 and the punch, and ensuring the stability of the material picking process.

[0074] The transfer unit 3 also includes a base 301, a column 302 on the base 301, a support 303 on the column 302, a module base plate 304 on the support 303, a module 305 mounted on the module base plate 304, a sensor fixing 306 on the module base plate 304, and a sensor 1 on the sensor fixing 306. The sensor 1 is set to detect whether the stamping is successfully picked up.

[0075] After the stamping sheet is in the feeding station, module 2 305 drives vacuum nozzle 1 311 forward to be above the stamping sheet. The upper and lower cylinders 307 move downward to make vacuum nozzle 1 311 contact the stamping sheet and pick it up. After the stamping sheet is picked up, the upper and lower cylinders 307 reset. Module 2 305 moves backward to move the stamping sheet above the positioning and imaging unit 4. The upper and lower cylinders 307 move downward to place the stamping sheet on the hollow rotating wheel 406. The upper and lower cylinders 307 reset, completing the process of picking up the stamping sheet from the feeding unit 1 to the positioning and imaging unit 4.

[0076] To broaden the applicability of this device, such as Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 7 , Figure 9 As shown, a tooling adapter plate 203 is detachably installed on the adapter base plate 202, and stacked tooling is set on the tooling adapter plate 203; the suction nozzle base plate 310 and the vacuum suction nozzle 311 are detachably connected; the output end of the four-axis robot 502 is detachably connected to the vacuum suction nozzle 506; a tooling adapter plate 718 is detachably installed on the adapter base plate 719, and stacked tooling is set on the tooling adapter plate 718.

[0077] When stacking different specifications of laminations, simply replace the corresponding stacking tooling with tooling adapter plate 1 203 or tooling adapter plate 2 718, and vacuum nozzle 1 311 or vacuum nozzle 2 506. The laminations are suitable for different specifications, mainly including more than a dozen products with diameters ranging from Φ20mm to Φ100mm.

[0078] like Figure 1 , Figure 2 , Figure 10 As shown, a dual-station stamping stacking device also includes a receiving unit 8, which is configured to collect the stampings when defects are detected.

[0079] The receiving unit 8 includes a support plate 801 mounted on the base 501. A receiving fixture 802 is provided on the support plate 801. The receiving fixture 802 is characterized by having a longitudinally arranged long shaft.

[0080] When the positioning and imaging unit 4 detects a defect in the stamping, including defects in the stamping itself or incorrect positioning of the stamping's assembly surface, the vacuum nozzle 506 in the stacking unit 5 picks up the stamping and moves it to the receiving unit 8, where the stamping is sleeved on the long shaft.

[0081] The stacking process of this dual-station lamination stacking device includes the following steps:

[0082] 1. Feeding unit 1: Workers load stacks of stamped sheets onto mandrel 108, with automatic feeding switching between four stations;

[0083] 2. Stacking tooling unit 2: The worker places the stacking tooling on the tooling adapter plate 203, and module 201 moves the stacking tooling backward to the predetermined position.

[0084] 3. Transfer unit 3, in which vacuum nozzle 311 picks up the blank from the feeding unit 1 and transfers the blank to the positioning and imaging unit 4;

[0085] 4. Positioning and imaging unit 4: Positioning and imaging unit 4 identifies the front and back of the stamping, locates the center of the stamping, and simultaneously identifies stamping defects;

[0086] 5.
