Description

Technical Field

[0001] This invention relates to the field of double stator core processing technology, specifically to a double stator core stacking equipment and method. Background Technology

[0002] A double stator core is a special stator core structure used in electric motors and engines. Its core feature is the inclusion of two stator core units, commonly arranged in two ways: one is two independent annular stator cores arranged coaxially side-by-side; the other is an inner stator core and an outer stator core distributed concentrically (integrated by a connecting part). Its advantages include increased motor power density and optimized operating efficiency (such as achieving dual-frequency output and reducing energy consumption). It is widely used in special motors and new energy-related motors. The structural precision and molding quality directly determine the power performance, operational stability, and service life of the motor or engine.

[0003] With the rapid development of industries such as new energy vehicles and high-end equipment manufacturing, the market demand for motor and engine manufacturing capacity continues to rise, while also placing more stringent requirements on production cost control. To reduce the manufacturing cost of double stator cores and avoid problems such as low material utilization and high mold investment during the processing of a single core, the industry generally adopts a processing strategy of dividing the entire core into multiple individual pieces. This strategy, by individually stamping each core piece, can significantly improve material utilization and reduce the R&D and manufacturing costs of a single set of molds, making it particularly suitable for multi-specification, small-batch core production scenarios.

[0004] During the iron core stacking process, individual pieces need to be spliced ​​together to form a whole piece, and then the whole piece is stacked. This process requires a lot of equipment, and misalignment can easily occur during the transfer of equipment processes, affecting the quality of the final iron core stacking. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a double-stator core stacking device and method. The main purpose is to solve the problem that in the core stacking process, individual pieces need to be spliced ​​together to form a whole piece, and then the whole piece is stacked.

[0026] A method for stacking double stator cores includes the following steps:

[0027] S1: The single-piece feeding assembly can accurately transport the single piece to the end, and then the single-piece assembly assembly uses the grippers to accurately pick up the single piece and place it into the positioning slot of the placement tray, thus completing the initial assembly of the single piece.

[0028] S2: Then, the placement tray rotates and, in conjunction with the single-piece feeding component, completes the installation of each single piece in the placement tray, and realizes the first-to-last splicing assembly of multiple single pieces;

[0029] S3: The station rotation component can drive the rotating disk to rotate, so that the placement disk installed on the rotating disk passes through the corresponding positions of the single-piece assembly component, the single-piece pressing component, and the position adjustment component in sequence, realizing the automated continuous operation of single-piece assembly and stacking spot welding of the iron core.

[0030] S4: After the first splicing is completed, multiple individual pieces are moved to the individual piece pressing component. The individual piece pressing component can press multiple individual pieces together at the same time. Then, the individual piece welding component can be used to spot weld the individual pieces together to initially fix the adjacent individual pieces together.

[0031] S5: Then, the multiple individual pieces that have been spot-welded and fixed are combined into a whole piece. At this time, the whole piece is moved to the position adjustment component. The whole piece clamping component of the position adjustment component uses at least three sets of jaws to clamp the spot-welded whole piece and place it on the arrangement component for stacking.

[0032] S6: After stacking, the entire stacked piece is pressed together by the overall pressing assembly. At the same time, the entire stacked piece is welded together by the overall welding assembly, thus completing the stacking and assembly of the double stator core.

[0033] Compared with the prior art, the present invention provides a double stator core stacking device and method, which has the following beneficial effects:

[0034] 1. This invention enables continuous production from single-piece feeding and alignment, assembly and pressing welding, to whole-piece clamping and stacking, and overall pressing welding. Each step is coordinated by sensors, positioning cylinders and independent drives, reducing human intervention errors. The equipment has a high degree of integration, which effectively improves stacking efficiency.

[0035] 2. The gripper of the present invention is provided with a clamping chamber and a clamping slide, and the clamping cylinder drives the precise clamping of single pieces; the single piece feeding assembly forms a aligning chamber through an aligning plate, a push block and a stop block, and combined with the positioning of the conveyor belt, ensures accurate feeding position and meets the stacking accuracy.

[0036] 3. This invention uses a rotating assembly at the workstation to mount four placement trays on a rotating disk. Drive mechanism one rotates independently to adjust the angle of each tray, and drive mechanism two drives the entire assembly to rotate and switch workstations via a reduction gearbox. Positioning cylinder one is precisely positioned with positioning pin holes, and support rollers assist in load reduction, thereby achieving continuous automation of multiple processes and improving efficiency.

[0037] 4. The whole piece clamping component of the position adjustment component of the present invention uses three sets of grippers to clamp the whole piece and moves it to the arrangement component via a rotating shaft; the arrangement component controls the falling distance by means of an arrangement cylinder and a laser displacement sensor, and the profiling frame squeezes and shapes it during stacking to ensure stacking accuracy.

[0038] 5. The present invention presses the single-piece pressing component before welding to prevent displacement, and presses the entire pressing component twice after stacking. The double pressing combined with laser welding makes the single piece and the whole piece firmly connected, enhancing the overall stability of the iron core. Attached Figure Description

[0059] Please see Figures 1-16 As shown, a double stator core stacking device includes a workbench 1. At least four sets of placement trays 11 are installed on the top of the workbench 1 via a rotating disk 201 of a station rotation assembly 2. On the upper surface of the workbench 1 and around the station rotation assembly 2, a single-piece assembly assembly 3, a single-piece pressing assembly 5, a single-piece welding assembly 6, a position adjustment assembly 7, an arrangement assembly 8, and an overall welding assembly 9 are sequentially installed. On the top of the workbench 1 and on one side of the single-piece assembly assembly 3, a single-piece feeding assembly 4 is provided for feeding single pieces.

[0060] Position adjustment assembly 7 includes an opposing integral clamping assembly 701 and an integral pressing assembly 702;

[0061] The single-piece assembly 3 is equipped with at least one set of grippers 10 for clamping single pieces, and the whole-piece clamping assembly 701 is equipped with at least three sets of grippers 10 for clamping whole pieces.

[0062] The gripper 10 includes a frame 1001 and a gripping cylinder 1002 installed in the frame 1001. The bottom of the frame 1001 is provided with a snap-fit ​​chamber 1003 that conforms to the shape of a single piece. The inside of the frame 1001 is provided with a clearance cavity 1006. A gripping slide 1005 that is fixedly connected to the end of the piston rod of the gripping cylinder 1002 is slidably installed in the clearance cavity 1006. The bottom of the gripping slide 1005 is provided with a snap-fit ​​part 1004 that cooperates with the snap-fit ​​chamber 1003.

[0063] The clamping cylinder 1002 drives the clamping slide 1005 to perform linear reciprocating motion within the clearance cavity 1006. When the clamping slide 1005 moves to the left (see reference). Figure 8 The fastening part 1004 will enter the fastening chamber 1003 and fasten tightly with the single piece to achieve stable clamping of the single piece; when the clamping slide 1005 moves to the right, the single piece will be released.

[0064] This design enables the gripper 10 to accurately and reliably clamp single pieces, meeting the process requirements of the double stator core stacking equipment during production.

[0065] The placement tray 11 has multiple inner openings 1102 and clearance openings 1103 on its inner and outer rings, respectively. The upper surface of the placement tray 11 has multiple positioning grooves 1101 that cooperate with the single piece. The inner openings 1102 and clearance openings 1103 of the placement tray 11 provide clearance space for the operation of other components during operation, while the positioning grooves 1101 ensure the stability of the single piece during placement and operation.

[0066] Currently, in order to save on manufacturing and processing costs, the entire iron core is divided into multiple individual pieces. Then, during the iron core stacking process, the individual pieces need to be spliced ​​together to form a whole piece, and then the whole piece is stacked. This process requires a lot of equipment, and misalignment can easily occur during the transfer of equipment processes, affecting the quality of the final iron core stacking.

[0067] Specifically, the assembly and stacking of individual wafers involves the following steps:

[0068] Step 1: The single-piece feeding assembly 4 can accurately transport the single piece to the end, and then the single-piece assembly assembly 3 uses the gripper 10 to accurately pick up the single piece and place it into the positioning slot 1101 of the placement tray 11 to complete the initial assembly of the single piece.

[0069] Step 2: Then, the placement tray 11 rotates and, in cooperation with the single-piece feeding component 4, completes the installation of single pieces one by one in the placement tray 11, and realizes the first-to-last splicing assembly of multiple single pieces;

[0070] Step 3: The station rotation component 2 can drive the rotating disk 201 to rotate, so that the placement disk 11 installed on the rotating disk 201 passes through the corresponding positions of the single-piece assembly component 3, the single-piece pressing component 5, and the position adjustment component 7 in sequence, thereby realizing the automated continuous operation of single-piece assembly and stacking spot welding of the iron core.

[0071] Step 4: After the first and second pieces are spliced ​​together, they are moved to the single piece pressing component 5. The single piece pressing component 5 can press the multiple pieces together at the same time. Then, the single piece welding component 6 is used to spot weld the pieces together to initially fix the adjacent pieces together.

[0072] Step 5: Then, the multiple individual pieces that have been spot-welded and fixed are assembled into a whole piece. At this time, the whole piece is moved to the position adjustment component 7. The whole piece clamping component 701 of the position adjustment component 7 uses at least three sets of jaws 10 to clamp the spot-welded whole piece and place it on the arrangement component 8 for stacking.

[0073] Step Six: After stacking, the entire stacked piece is pressed together by the overall pressing assembly 702. At the same time, the entire stacked piece is welded by the overall welding assembly 9, thereby completing the stacking and assembly of the double stator core.

[0074] The workstation rotation assembly 2 of the present invention includes a rotary drive reduction gearbox 208 connected to a rotary disk 201. The rotary drive reduction gearbox 208 is installed on the upper surface of the workbench 1. Four sets of placement disks 11 are all arranged on the rotary disk 201. The lower surface of the rotary disk 201 is provided with a drive mechanism 206 for driving the placement disks 11 to rotate. The workbench 1 is equipped with a drive mechanism 207 for driving the rotary drive reduction gearbox 208.

[0075] Specifically, the drive mechanism 206 can drive the placement disk 11 to rotate independently to meet the angle adjustment requirements of different single pieces during the assembly process.

[0076] The second drive mechanism 207 drives the rotary disk 201 to rotate as a whole through the rotary drive reduction gearbox 208, thereby realizing the switching of work positions.

[0077] At least four sets of support frames 204 are installed on the top of the workbench 1. Support rollers 205, which rotatably contact the lower surface of the rotating disk 201, are mounted on the top of the support frames 204 via bearings. The support frames 204 and the support rollers 205 constitute an auxiliary support structure, ensuring stable operation of the rotating disk 201 while reducing the load on the rotary drive reduction gearbox 208. The outer ring of the rotating disk 201 has four positioning pin holes 203 corresponding to the placement disk 11. A positioning cylinder 202 (which can be YHDB40X30) is installed on the top of the workbench 1, engaging with the positioning pin holes 203. The positioning cylinder 202, through its telescopic movement, engages with the positioning pin holes 203 to achieve precise positioning when the rotating disk 201 rotates to the designated position, preventing misalignment during assembly and thus avoiding processing errors. The four sets of support frames 204 are evenly distributed along the rotating disk 201. The support rollers 205 can be made of high-hardness alloy material, with a surface hardened to improve wear resistance, thereby extending the equipment's service life.

[0078] The single-piece assembly component 3 of the present invention includes a single-piece assembly ball screw linear module 301 mounted on the upper surface of the workbench 1. A single-piece assembly frame 302 is mounted on the slide of the single-piece assembly ball screw linear module 301. A single-piece assembly carriage 304 is slidably mounted inside the single-piece assembly frame 302. A single-piece assembly connecting frame 305 is fixed to one side of the single-piece assembly carriage 304 by bolts. The end of the single-piece assembly connecting frame 305 is fixed to a gripper 10. A single-piece assembly cylinder 303 is installed inside the single-piece assembly frame 302 to drive the single-piece assembly carriage 304 to move up and down.

[0079] Specifically, the single-piece assembled ball screw linear module 301 can drive the single-piece assembled frame 302 to perform linear motion in the horizontal direction, thereby adjusting the position of the gripper 10 in the horizontal direction.

[0080] Meanwhile, the single-piece assembly cylinder 303 drives the single-piece assembly carriage 304 to slide up and down inside the single-piece assembly frame 302 through its telescopic movement, thereby driving the gripper 10 to move in the vertical direction. The single-piece assembly connecting frame 305 serves to connect the single-piece assembly carriage 304 and the gripper 10, ensuring that the gripper 10 can move stably with the movement of the single-piece assembly carriage 304;

[0081] This enables precise positioning and assembly operations for picking up and placing individual pieces.

[0082] The single-piece feeding assembly 4 of the present invention includes a single-piece feeding frame 402 and a conveyor belt 401 installed on the upper surface of the workbench 1. A single-piece feeding cylinder 403 is fixed to one side of the single-piece feeding frame 402 by bolts. A single-piece transverse alignment finger cylinder 404 is fixed to one end of the piston rod of the single-piece feeding cylinder 403 by bolts. Alignment plates 405 are fixed to both clamps of the single-piece transverse alignment finger cylinder 404 by bolts. A single-piece longitudinal alignment stop block 406 and a single-piece longitudinal alignment cylinder 408 are respectively installed on both sides of the end of the conveyor belt 401. A single-piece longitudinal alignment push block 407 that cooperates with the single-piece longitudinal alignment stop block 406 is fixed to one end of the piston rod of the single-piece longitudinal alignment cylinder 408 by bolts. The single-piece longitudinal alignment stop block 406, the single-piece longitudinal alignment push block 407 and the two alignment plates 405 form an alignment chamber that constrains the single piece in the entire circumference.

[0083] Specifically, the conveyor belt 401 is used to transport individual pieces to a designated position. The conveyor belt 401 is equipped with a proximity switch to determine the position of the individual pieces. The individual pieces on the conveyor belt 401 are placed sequentially and at intervals by a robotic arm. The conveyor belt 401 has a support plate inside to support the conveyor belt and prevent the conveyor belt from collapsing. In addition, the conveyor belt 401 is existing technology.

[0084] When the single piece is conveyed to the end, the conveyor belt 401 stops;

[0085] At this time, the single-piece feeding cylinder 403 is started, which drives the single-piece lateral alignment finger cylinder 404 to move to the appropriate position. The two clamping arms of the single-piece lateral alignment finger cylinder 404 drive the alignment plate 405 to move, and adaptively align the single piece in the lateral direction. At this time, the two clamping arms only maintain the limiting state of the single piece (not clamping the single piece).

[0086] Then, the single-piece longitudinal alignment cylinder 408 is activated, pushing the single-piece longitudinal alignment push block 407 to move towards the single-piece longitudinal alignment stop block 406, thereby aligning the single piece in the longitudinal direction.

[0087] This vertical and horizontal alignment operation ensures that each piece is precisely positioned within the alignment chamber, preparing it for subsequent loading operations.

[0088] The single-piece pressing assembly 5 of the present invention includes a single-piece pressing frame 501 fixed to the upper surface of the workbench 1 by bolts. A single-piece pressing ball screw linear module 502 is fixed to one side of the single-piece pressing frame 501 by bolts. A single-piece pressing slide 503 is fixed to one side of the slide of the single-piece pressing ball screw linear module 502 by bolts. A single-piece pressing rotating shaft 505 is rotatably installed inside the single-piece pressing slide 503 through a bearing seat. A pressing inner frame 506 is fixed to the bottom end of the single-piece pressing rotating shaft 505 by bolts. A plurality of pressing outer frames 507 for pressing the single piece are installed on the outer ring of the pressing inner frame 506. The center line of the pressing inner frame 506 and the pressing outer frame 507 coincides with the center line of the placement tray 11.

[0089] The outer ring of the inner pressing frame 506 is equipped with multiple fasteners 508 that cooperate with the inner opening 1102 of the placement plate 11. The top of the single pressing slide 503 is fixed with a positioning cylinder 2 504 by bolts, and one end of the piston rod of the positioning cylinder 2 504 can be inserted into the side wall of the top of the single pressing rotating shaft 505.

[0090] The single-piece welding assembly 6 includes a single-piece welding frame 601 fixed to the upper surface of the workbench 1 by bolts. A single-piece welding ball screw linear module 602 is installed on the top of the single-piece welding frame 601. A single-piece welding slide 603 is installed on the slide of the single-piece welding ball screw linear module 602. A single-piece welding laser welding gun 604 for spot welding between two adjacent single pieces is installed on one side of the single-piece welding slide 603.

[0091] Specifically, when the single-piece pressing component 5 is working, the single-piece pressing ball screw linear module 502 is activated, driving its slide to move, which in turn causes the single-piece pressing slide 503 to move accordingly. The movement of the single-piece pressing slide 503 causes the inner pressing frame 506 and the outer pressing frame 507 to continue to descend until the buckle 508 is inserted into the inner opening 1102 of the placement tray 11. Then, the piston rod of the positioning cylinder 2 504 shortens and releases the locking state of the single-piece pressing rotating shaft 505, thereby realizing the precise pressing operation on the single piece assembled in the placement tray 11. Since the single-piece pressing rotating shaft 505 is in a rotating state, the inner pressing frame 506 and the outer pressing frame 507 can rotate with the placement tray 11 and always maintain the pressing state on the single piece assembled in the placement tray 11.

[0092] When the single-piece welding assembly 6 is working, the single-piece welding ball screw linear module 602 is activated, driving its slide to move, which in turn moves the single-piece welding carriage 603. The single-piece welding carriage 603 drives the single-piece welding laser welding gun 604 to the position where welding is required between two adjacent single pieces (single-piece connection weld bevel). Then, the single-piece welding laser welding gun 604 is activated to perform spot welding between two adjacent single pieces. After the welding is completed, the single-piece welding ball screw linear module 602 drives the single-piece welding laser welding gun 604 to reset. Then, the drive mechanism 206 drives the placement plate 11 to rotate independently to the next two adjacent single pieces. The above actions are repeated to complete the spot welding and fixing operation between multiple single pieces.

[0093] After the spot welding is completed, the piston rod of the positioning cylinder 504 extends and locks the single-piece pressing rotating shaft 505. Only then can the single-piece pressing ball screw linear module 502 be activated to move upward and release the pressing state of the assembled single piece in the placement tray 11. This operation can also prevent the inner pressing frame 506 and the outer pressing frame 507 from rotating, ensuring that the inner pressing frame 506 and the outer pressing frame 507 are always aligned with the placement tray 11.

[0094] The position adjustment component 7 in this invention includes an integral pressing drive reduction gearbox 703 and an integral pressing rotating shaft 705. The integral pressing rotating shaft 705 is connected to the integral pressing drive reduction gearbox 703. The integral pressing drive reduction gearbox 703 is installed on the upper surface of the workbench 1. The lower surface of the workbench 1 is provided with a drive mechanism 704 for driving the integral pressing drive reduction gearbox 703. The whole piece clamping component 701 and the integral pressing component 702 are respectively installed on the top two sides of the integral pressing rotating shaft 705.

[0095] The integral clamping assembly 701 includes an integral clamping side frame 70101 that is fixed to one side of the integral pressing rotating shaft 705 by bolts. An integral clamping ball screw linear module 70102 is installed on one side of the integral clamping side frame 70101. An integral clamping slide 70103 is installed on the slide table of the integral clamping ball screw linear module 70102. An integral clamping mounting frame 70104 is fixed to the end of the integral clamping slide 70103 by bolts. Three sets of grippers 10 are installed at the bottom of the integral clamping mounting frame 70104.

[0096] The arrangement assembly 8 includes an arrangement mounting carriage 801 that is slidably installed inside the worktable 1. The top of the arrangement mounting carriage 801 is fixed with an upper mounting plate 805 by bolts. One of the placement trays 11 is installed on the upper mounting plate 805. A drive mechanism 206 that cooperates with the placement tray 11 is installed on the lower surface of the upper mounting plate 805.

[0097] The workbench 1 is equipped with an arrangement cylinder 802 that drives the arrangement and mounting slide 801 to move up and down. A sensing plate 804 is fixed to one side of the arrangement and mounting slide 801 by bolts. A laser displacement sensor 803 (model: PDL-030-485) that cooperates with the sensing plate 804 is installed on the upper surface of the workbench 1.

[0098] Specifically, when the position adjustment component 7 is working, the drive mechanism 3 704 is started, which drives the overall pressing drive reduction gearbox 703 to operate, thereby causing the overall pressing rotating shaft 705 to rotate. The whole clamping component 701 and the overall pressing component 702 rotate together with the overall pressing rotating shaft 705.

[0099] During clamping, the entire clamping ball screw linear module 70102 is activated, and its slide table drives the entire clamping slide 70103 to move downward. The entire piece (the single piece after splicing and assembly) is clamped by the entire clamping mounting frame 70104 and three sets of grippers 10. The clamped piece is moved to the position of the arrangement component 8 by the drive mechanism 704.

[0100] When the arranging assembly 8 is working, the arranging cylinder 802 is activated, pushing the arranging mounting carriage 801 to move up and down inside the worktable 1. This, in turn, moves the upper mounting plate 805 and the placement tray 11 mounted on the upper mounting plate 805 up and down, thus adjusting the height of the placement tray 11. During the movement of the arranging mounting carriage 801, the sensing plate 804 moves along with it. The laser displacement sensor 803 senses the position of the sensing plate 804 in real time and feeds the signal back to the control system to accurately control the moving distance of the arranging mounting carriage 801, ensuring that the placement tray 11 reaches the accurate position.

[0101] Therefore, after stacking a whole piece, the slide 801 is arranged and installed, and then falls. The falling distance is the thickness of a whole piece. This stacking is carried out until multiple whole pieces are stacked.

[0102] The integral press assembly 702 includes an integral press side frame 70201 that is fixed to the other side of the integral press rotation shaft 705 by bolts. The bottom end of the integral press side frame 70201 is rotatably mounted with an integral press profile frame 70202 via a bearing seat.

[0103] It should be noted that after each stack of the whole piece is completed, the overall pressing and shaping frame 70202 needs to be moved to the position of the arrangement component 8 by the drive mechanism 704; then the arrangement cylinder 802 is activated to extend, so that the stacked whole piece contacts and is pressed with the overall pressing and shaping frame 70202, thereby completing the shaping and pressing operation of each stacked whole piece.

[0104] Furthermore, drive mechanism 1 206, drive mechanism 2 207, and drive mechanism 3 704 are all composed of two synchronous pulleys, a synchronous belt, and a self-locking geared motor. The motor used is a servo motor with an encoder. The number of rotations and rotation angle of the motor output shaft are controllable and have high precision. Those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0105] The integral welding assembly 9 of the present invention includes an integral welding frame 901 installed on the upper surface of the workbench 1. An integral welding ball screw linear module 902 is fixed to one side of the integral welding frame 901 by bolts. An integral welding slide 903 is installed on the slide of the integral welding ball screw linear module 902. An integral welding laser welding gun 904 for performing pull welding operations on the stacked whole piece is installed on one side of the integral welding slide 903.

[0106] Specifically, during the overall welding process, the overall welding ball screw linear module 902 is activated, driving its slide to perform precise vertical linear motion, which in turn moves the overall welding slide 903 to the designated position. At this time, the overall welding laser welding gun 904 starts working, performing spot welding (press-fitting and pulling welding bevel) on the stacked pieces on the placement tray 11 to ensure a firm connection between the pieces and form a stable overall structure.

[0107] It should be noted that the laser welding gun used in this application is prior art, and those skilled in the art can set it up according to actual needs, which will not be elaborated here.

[0108] At this time, after a pull welding operation is completed, the overall welding ball screw linear module 902 is reset, and then the stacked piece on the placement plate 11 mounted on the upper mounting plate 805 is driven to rotate to the next pull welding position by the drive mechanism 206. The above actions are repeated to complete the overall pull welding operation of the stacked piece.

[0109] It should be noted that the ball screw linear module in this application is prior art. It achieves precise linear motion through the cooperation of various components: the slide table is the moving part, the ball screw and guide rail form the transmission core, the motor and coupling provide power, and the aluminum alloy profile and support base ensure structural stability. In addition, by cooperating with magnetic switches, proximity switches or photoelectric switches, the displacement of the slide table can be precisely controlled. Those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0110] The operating procedure of the double stator core stacking equipment includes the following steps:

[0111] S1: The single pieces on the conveyor belt 401 are placed sequentially and intermittently by the robotic arm. When the single piece is conveyed to the end, the conveyor belt 401 stops. At this time, the single piece feeding cylinder 403 is started, which drives the single piece lateral alignment finger cylinder 404 to move to the appropriate position. The two clamping arms of the single piece lateral alignment finger cylinder 404 drive the alignment plate 405 to move, and adaptively align the single piece in the lateral direction. At this time, the two clamping arms only maintain the limiting state of the single piece (not clamping the single piece). Then, the single piece longitudinal alignment cylinder 408 is started, which pushes the single piece longitudinal alignment push block 407 to move towards the single piece longitudinal alignment stop block 406, and aligns the single piece in the longitudinal direction. Through the longitudinal and lateral alignment operations, the single piece is accurately positioned in the alignment chamber, which is ready for the subsequent feeding operation.

[0112] S2: Then, the single-piece assembly ball screw linear module 301 can drive the single-piece assembly frame 302 to perform horizontal linear movement, thereby adjusting the position of the gripper 10 in the horizontal direction. At the same time, the single-piece assembly cylinder 303 drives the single-piece assembly slide 304 to slide up and down inside the single-piece assembly frame 302 through telescopic action, thereby driving the gripper 10 to move in the vertical direction. Thus, the single piece is picked up from the conveyor belt 401 and placed in the placement tray 11. Then, the placement tray 11 rotates and cooperates with the single-piece feeding component 4 to complete the installation of the single pieces one by one in the placement tray 11, and realize the first-to-last splicing assembly of multiple single pieces.

[0113] S3: After the single piece is spliced ​​and assembled into a whole piece, the second drive mechanism 207 drives the rotary disk 201 to rotate as a whole through the rotary drive reduction gearbox 208, so as to switch the workstation to the position of the single piece pressing component 5.

[0114] S4: At this time, the single-piece pressing ball screw linear module 502 is activated, driving its slide to move, which in turn causes the single-piece pressing slide 503 to move accordingly. The movement of the single-piece pressing slide 503 causes the inner pressing frame 506 and the outer pressing frame 507 to continue to descend until the buckle 508 is inserted into the inner opening 1102 of the placement tray 11. Then, the piston rod of the positioning cylinder 2 504 shortens and releases the locking state of the single-piece pressing rotating shaft 505, thereby realizing the precise pressing operation of the single piece assembled in the placement tray 11. Since the single-piece pressing rotating shaft 505 is in a rotating state, the inner pressing frame 506 and the outer pressing frame 507 can rotate with the placement tray 11 and always maintain the pressing state of the single piece assembled in the placement tray 11.

[0115] S5: When the single-piece welding assembly 6 is working, the single-piece welding ball screw linear module 602 is started, driving its slide table to move, causing the single-piece welding carriage 603 to move. The single-piece welding carriage 603 drives the single-piece welding laser welding gun 604 to move to the position where welding is required between two adjacent single pieces (single-piece connection weld bevel). Then the single-piece welding laser welding gun 604 is started to perform spot welding between two adjacent single pieces. After the welding is completed here, the single-piece welding ball screw linear module 602 drives the single-piece welding laser welding gun 604 to reset. Then the drive mechanism 206 drives the placement plate 11 to rotate independently to the next two adjacent single pieces. The above actions are repeated to complete the spot welding and fixing operation between multiple single pieces.

[0116] S6: After the spot welding and fixing operation is completed, the piston rod of the positioning cylinder 2 504 extends and locks the single-piece pressing rotating shaft 505. Only then can the single-piece pressing ball screw linear module 502 be activated to move upward and release the pressing state of the single piece assembled in the placement tray 11. This operation can also prevent the pressing inner frame 506 and the pressing outer frame 507 from rotating, ensuring that the pressing inner frame 506 and the pressing outer frame 507 are always aligned with the placement tray 11.

[0117] S7: After the spot welding of the whole piece is completed, the drive mechanism 207 drives the rotary disk 201 to rotate as a whole through the rotary drive reduction gearbox 208, so as to switch the workstation to the position of the position adjustment component 7.

[0118] S8: During clamping, the entire clamping ball screw linear module 70102 is started, and its slide table drives the entire clamping slide 70103 to move downward. The entire piece (the single piece after splicing and assembly) is clamped by the entire clamping mounting frame 70104 and three sets of grippers 10. The clamped piece is moved to the position of the arrangement component 8 by the drive mechanism 704.

[0119] S9: When the arranging assembly 8 is working, the arranging cylinder 802 is activated, pushing the arranging mounting carriage 801 to move up and down inside the worktable 1, thereby driving the upper mounting plate 805 and the placement tray 11 mounted on the upper mounting plate 805 to move up and down, realizing the adjustment of the height of the placement tray 11; during the movement of the arranging mounting carriage 801, the sensing plate 804 moves along with it, and the laser displacement sensor 803 senses the position of the sensing plate 804 in real time, so as to accurately control the moving distance of the arranging mounting carriage 801 and ensure that the placement tray 11 reaches the target height. To ensure accurate positioning, after stacking a whole piece, the mounting carriage 801 falls, with a falling distance equal to the thickness of the whole piece. This stacking process continues until multiple whole pieces are stacked (and after each whole piece is stacked, the overall pressing and shaping frame 70202 needs to be moved to the position of the arrangement component 8 via the drive mechanism 704; then, the arrangement cylinder 802 is activated to extend, so that the stacked whole piece contacts and is pressed against the overall pressing and shaping frame 70202, thus ensuring that each stacked whole piece can be shaped and pressed).

[0120] S10: After the stacking of the whole pieces is completed, the stacked pieces on the placement tray 11 are then pressed by the overall pressing and shaping frame 70202.

[0121] S11: Then the integral welding ball screw linear module 902 is started, driving the slide table to perform precise lifting and lowering linear motion, thereby moving the integral welding slide 903 to the designated position. At this time, the integral welding laser welding gun 904 starts working, performing spot welding (press-fitting pull welding weld bevel) on the stacked pieces on the placement plate 11 to ensure that each piece is firmly connected and forms a stable integral structure. After completing one pull welding operation, the integral welding ball screw linear module 902 is reset. Then the stacked pieces on the placement plate 11 mounted on the upper mounting plate 805 are driven to rotate to the next pull welding position by the drive mechanism 206. The above actions are repeated to complete the integral pull welding operation of the stacked pieces.

[0122] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0123] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.

A method for stacking double stator cores, applicable to the double stator core stacking equipment described in claim 1, characterized in that, Includes the following steps: S1: The single-piece feeding assembly (4) can accurately transport the single piece to the end, and then the single-piece assembly assembly (3) uses the gripper (10) to accurately pick up the single piece and place it into the positioning slot (1101) of the placement tray (11) to complete the initial assembly of the single piece; S2: Then, the placement tray (11) rotates and, in cooperation with the single-piece feeding component (4), completes the installation of single pieces one by one in the placement tray (11) and realizes the first-to-last splicing assembly of multiple single pieces; S3: The station rotation component (2) can drive the rotating disk (201) to rotate so that the placement disk (11) installed on the rotating disk (201) passes through the positions corresponding to the single-piece assembly component (3), the single-piece pressing component (5), and the position adjustment component (7) in sequence, thereby realizing the automated continuous operation of assembling the single pieces of the iron core and stacking spot welding. S4: After the first splicing is completed, multiple single pieces are moved to the single piece pressing component (5). The single piece pressing component (5) can press multiple pieces together at the same time, and then the single piece welding component (6) can be used to spot weld the single pieces to initially fix the adjacent single pieces together. S5: Then, the multiple single pieces after spot welding are assembled into a whole piece. At this time, the whole piece is moved to the position adjustment component (7). The whole piece clamping component (701) of the position adjustment component (7) uses at least three sets of jaws (10) to clamp the spot-welded whole piece and place it on the arrangement component (8) for stacking operation. S6: After stacking, the entire stacked piece is pressed by the overall pressing assembly (702). At the same time, the entire stacked piece is welded by the overall welding assembly (9) to complete the stacking and assembly of the double stator core.
