Description

Technical Field

[0001] This invention relates to the technical field of automated equipment, specifically to an integrated machine for welding motor stator and inserting paper. Background Technology

[0002] The existing motor stator welding device and the motor stator slotting paper machine are set up separately and independently. The motor stator slotting paper machine inserts insulating paper into the motor stator slot. The detailed structure of the motor stator slotting paper machine can be found in Chinese Patent Publication No. CN114172331A, which discloses a dual-station vertical slotting paper machine, which includes a slotting paper cutting device, a slotting paper pushing device, and a slotting paper forming assembly. The slotting paper cutting device and the slotting paper pushing device operate independently and have no linkage structure. Moreover, this slotting paper machine is designed for motor stator slots with uniform shape and size, so it does not have a cutter adjustment device. In addition, the slotting paper pushing device is operated by a cylinder, but because the equipment runs for a long time during production, that is, the slotting paper pushing device needs to be run multiple times, the cylinder has a short service life.

[0003] Based on the above, further improvements are needed. Summary of the Invention

[0004] This invention proposes an integrated machine for welding and inserting motor stators. By integrating the detection mechanism, laser welding mechanism, paper slotting mechanism, transfer mechanism, and turntable mechanism into a single machine body, it achieves integrated operation of motor stator welding and paper insertion, completely solving the problem of fragmented production processes caused by the separate installation of welding devices and paper slotting machines in existing technologies. Firstly, the integrated design significantly shortens the stator transfer path, eliminating the need for manual labor or additional equipment to transfer the stator between two independent machines. Simultaneously, it reduces the overall footprint of the equipment, optimizes the layout of the production workshop, and improves the utilization rate of factory space.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. In order to make the above-mentioned objects, features and advantages of this application more apparent and understandable, many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0034] See Figures 1-17 A motor stator welding and paper insertion integrated machine includes a machine body 2, and the motor stator welding and paper insertion integrated machine also includes: Testing mechanism 1, which is used to test the height of stator 3; Laser welding mechanism 4, which is used to weld stator 3; The paper slotting mechanism 5 includes a paper feeding device 501 for conveying insulating paper, a cutting device 502 for cutting insulating paper, a forming device 503 for shaping insulating paper, and a paper pushing device 504 for pushing the formed insulating paper into the slot of the stator 3. The transfer mechanism 7 is used to transfer the stator 3 after welding to the designated position of the slotted paper mechanism 5; The turntable mechanism 6 is used to position and support the stator 3. The detection mechanism 1, the laser welding mechanism 4 and the transfer mechanism 7 are all located above the turntable mechanism 6. During the rotation of the turntable mechanism 6, the stator 3 passes through the detection mechanism 1, the laser welding mechanism 4 and the transfer mechanism 7 in sequence.

[0035] By integrating the inspection mechanism 1, laser welding mechanism 4, paper slotting mechanism 5, transfer mechanism 7, and turntable mechanism 6 into the machine body 2, the stator welding and paper insertion of the motor are integrated into one operation, completely solving the problem of production process fragmentation caused by the separate setting of welding device and paper slotting machine in the existing technology. First, the integrated design significantly shortens the transfer path of stator 3, eliminating the need for manual or additional equipment to transfer stator 3 between two independent machines. At the same time, it reduces the overall footprint of the equipment, optimizes the layout of the production workshop, and improves the utilization rate of factory space.

[0036] The paper slotting mechanism 5, through the cooperation of the paper feeding device 501, the cutting device 502, the forming device 503 and the paper pushing device 504, realizes the fully automated processing of insulating paper "conveying-cutting-shaping-insertion", without the need for manual intervention in the insulating paper processing process, thus improving the paper insertion accuracy and efficiency; the transfer mechanism 7 automatically transfers the welded stator 3 to the paper slotting mechanism 5, ensuring the precise docking of the stator 3 between the two processes.

[0037] The turntable mechanism 6 includes a positioning fixture 601 for positioning the stator 3. The positioning fixture 601 is movably mounted on the turntable mechanism 6. The turntable mechanism 6 is provided with a lifting mechanism 8 below the laser welding mechanism 4 for lifting the positioning fixture 601. The laser welding mechanism 4 includes a pressure plate 401 and a downward pressure driver 402 that drives the pressure plate 401 to move towards the lifting mechanism 8. The output shaft of the downward pressure driver 402 is connected to the pressure plate 401 in a transmission manner. When the stator 3 is welded, the lifting mechanism 8 is activated to lift the positioning fixture 601 and the stator 3 together. The downward pressure driver 402 drives the pressure plate 401 to move downward, pressing the stator 3 onto the positioning fixture 601. The stator 3 is laser welded in the pressed state.

[0038] The positioning fixture 601 is specifically used for the initial positioning of the stator 3. During welding of the stator 3, the lifting mechanism 8 lifts the positioning fixture 601 and the stator 3 from below, while the downward driver 402 drives the pressure plate 401 to move downward from above, firmly pressing the stator 3 onto the positioning fixture 601, forming a bidirectional fixation. This bidirectional clamping ensures that the stator 3 maintains a stable posture during welding, preventing displacement and improving welding quality.

[0039] The turntable mechanism 6, as the core load-bearing and transfer component, drives the stator 3 through the inspection mechanism 1, the laser welding mechanism 4, and the transfer mechanism 7 in sequence, forming a streamlined "inspection-welding-transfer" operation mode. During the welding of the stator 3, the lifting mechanism 8 is activated, lifting the positioning fixture 601 and the stator 3 together. Because the laser welding mechanism 4 is equipped with a pressing device to press down on the positioning stator 3 during stator welding, after the positioning fixture 601 and the stator 3 are lifted, the pressing device acts on the stator 3 and the positioning fixture 601, thus preventing damage to the turntable 602 of the turntable mechanism 6 during welding.

[0040] The lifting mechanism 8 includes a top shaft 801, a slider 802, and a push cylinder 803. The slider 802 is slidably disposed at the lower part of the top shaft 801, and the end of the slider 802 is provided with an inclined surface 804. The piston rod of the push cylinder 803 is connected to the slider 802 to drive the slider 802 to move closer to or away from the top shaft 801. When the push cylinder 803 drives the slider 802 to move and the inclined surface 804 moves to below the top shaft 801, the top shaft 801 rises under the action of the inclined surface 804. When the push cylinder 803 drives the slider 802 to reset, the top shaft 801 descends to its initial state by its own weight or the action of the reset spring.

[0041] The lifting structure, consisting of a top shaft 801, a slider 802, a push cylinder 803, and an inclined plane 804, achieves stable lifting of the positioning fixture 601. The "inclined plane transmission" design converts the lateral driving force of the push cylinder 803 into the vertical lifting force of the top shaft 801, resulting in smoother transmission. When the slider 802 approaches the lower part of the positioning fixture 601, the positioning fixture 601 can rise along the inclined plane 804. When the slider 802 returns to its original position, the positioning fixture 601 can descend along the inclined plane 804. When the slider 802 completely disengages from the lower part of the positioning fixture 601, the positioning fixture 601 returns to its initial state. The descent of the top shaft 801 relies on its own gravity or a return spring to return to its initial state, eliminating the need for an additional power output element to drive the top shaft 801 to return to its original state. The action control of the cylinder 803 is simple. The reciprocating motion of the slider 802 can be achieved by switching the pneumatic system on and off, which simplifies the component composition of the lifting mechanism 8, thereby controlling the lifting and lowering of the top shaft 801, realizing automated linkage, and adapting to the needs of long-term continuous operation of the equipment.

[0042] The lifting mechanism 8 is equipped with a first detector 809 for detecting the lifting position of the top shaft 801; The lifting mechanism 8 also includes a fixed plate 805, a movable plate 806, a number of lifting guide columns 807 and a number of guide sleeves 808; The fixed plate 805 is fixedly mounted on the machine body 2; the movable plate 806 is mounted above the fixed plate 805; the upper end of each lifting guide column 807 is fixedly connected to the movable plate 806; each guide sleeve 808 is fixedly installed on the fixed plate 805; the lower end of each lifting guide column 807 is slidably inserted into the corresponding guide sleeve 808, thereby forming a lifting guide pair of the movable plate 806 relative to the fixed plate 805; the lower end of the top shaft 801 is connected to the movable plate 806, and the upper end of the top shaft 801 extends upward out of the movable plate 806; During the lifting process, the top shaft 801 drives the movable plate 806 and the lifting guide column 807 to move. The lower part of the lifting guide column 807 is provided with a limit block to constrain the upward stroke of the lifting guide column 807. The fixing plate 805 is provided with a first bracket 810 for fixing the first detector 809.

[0043] The first bracket 810 is provided with a fixing groove for limiting the installation of two first detectors 809. The first detectors 809 enable real-time monitoring and feedback of the lifting position of the top shaft 801. The lifting guide column 807 slides along the guide sleeve 808, which can limit the lateral displacement of the movable plate 806 and the top shaft 801, prevent the top shaft 801 from tilting or deviating during the lifting process, and ensure that the top shaft 801 always moves vertically.

[0044] The design of the first detector 809, fixed plate 805, movable plate 806, lifting guide column 807 and guide sleeve 808 further improves the accuracy, stability and safety of the lifting mechanism 8, providing multiple guarantees for the reliable operation of the welding process. Only when the top shaft 801 is detected to rise will the pressure plate 401 of the laser welding mechanism 4 move towards the lifting mechanism 8 to prevent damage to the turntable 602 in case of lifting failure.

[0045] The limit block can be fixed to the lifting guide column 807 by threads.

[0046] The laser welding mechanism 4 also includes a mounting plate 405, a lifting plate 403, several laser welding guns 404 and a drive assembly; The mounting plate 405 is used to fix the pressure driver 402, and the lifting plate 403 is arranged parallel to the bottom of the mounting plate 405; a plurality of laser welding guns 404 are inclinedly arranged on the lifting plate 403 and distributed in a circumferential array at intervals. The drive assembly includes a screw 406, a nut sleeve 407, and a lifting motor 409 fixed on a mounting plate 405; The upper part of the screw 406 passes through the mounting plate 405 and is connected to the output shaft of the lifting motor 409; the nut sleeve 407 is fixedly connected to the lifting plate 403, and the lower part of the screw 406 is inserted into the nut sleeve 407, forming a screw-nut pair with the nut sleeve 407 and the screw 406. A guide post 408 is provided between the mounting plate 405 and the lifting plate 403. The upper part of the guide post 408 is fixed to the mounting plate 405, and the lower part of the guide post 408 passes through the lifting plate 403. The guide post 408 is used to provide guidance and anti-torsional constraint for the lifting movement of the lifting plate 403. The lifting motor 409 drives the screw 406 to rotate, which in turn drives the lifting plate 403 and the laser welding gun 404 to move up and down along the guide direction of the guide post 408 through the nut sleeve 407. The mounting plate 405 is also provided with a fume suction nozzle 410 to suck up the fumes generated during the welding process of the stator 3. The machine body 2 is provided with a second detector 411 for detecting the lifting position of the lifting plate 403, and a second bracket 412 for fixing the second detector 411.

[0047] The guide post 408 provides key guidance and anti-torsional constraints for the lifting plate 403: When the lifting plate 403 drives multiple laser welding guns 404 to rise and fall, it is prone to rotation or deviation due to uneven force. The guide post 408 can limit the lateral displacement and rotation of the lifting plate 403, ensuring the welding angle and position of the laser welding guns 404 are accurate. The second detector 411 detects the lifting position of the lifting plate 403 in real time. If any abnormality occurs in the lifting (such as motor failure or lead screw jamming), the equipment alarm can be triggered in time.

[0048] The turntable mechanism 6 includes a turntable 602, and a plurality of positioning fixtures 601 are provided. The plurality of positioning fixtures 601 are arranged circumferentially on the turntable 602, and each positioning fixture 601 is movably arranged on the turntable 602. The turntable 602 is provided with a bearing 603 and a support rod 607 for fixing the bearing 603; The positioning fixture 601 includes a connector 604 and a positioning component 605. The connector 604 and the positioning component 605 are integrally formed. The connector 604 is sleeved around the bearing 603, and the positioning component 605 is located inside the bearing 603. The positioning component 605 is provided with a positioning mandrel 606 extending out of the upper outer side of the bearing 603. When the stator 3 is installed in the positioning fixture 601, the stator 3 is sleeved around the positioning mandrel 606. When the positioning fixture 601 moves up and down, the connecting piece 604 and the positioning piece 605 move up and down along the bearing 603. The turntable 602 has an opening 608 at the lower part of the positioning piece 605. When the turntable 602 rotates to the point where the positioning fixture 601 corresponds vertically to the top shaft 801 of the lifting mechanism 8, the top shaft 801 can pass upward through the opening 608 and push the bottom of the positioning piece 605, driving the entire positioning fixture 601 to move upward along the bearing 603.

[0049] The loading and transfer capabilities of the turntable mechanism 6 are optimized by using multiple positioning fixtures 601. Multiple positioning fixtures 601 are arranged circumferentially on the turntable 602. When the turntable 602 rotates, it can drive multiple stators 3 to rotate synchronously, realizing parallel operation of the three stations of "inspection-welding-transfer". When one stator 3 is being welded under the laser welding mechanism 4, another stator 3 can complete height detection under the inspection mechanism 1, and another welded stator 3 can be picked up and transferred by the transfer mechanism 7. There is no need to wait for a single stator 3 to complete all processes before proceeding to the next one, which greatly shortens the production cycle and reduces equipment downtime.

[0050] The positioning mandrel 606 on the positioning component 605 provides precise center positioning for the stator 3: when the stator 3 is fitted around the positioning mandrel 606, its center position is strictly limited, ensuring that the placement reference of each stator 3 on the turntable 602 is consistent, and avoiding errors in subsequent inspection, welding, and transfer processes due to the initial positioning offset of the stator 3.

[0051] The opening 608 at the bottom of the positioning piece 605 corresponds to the turntable 602, providing working space for the top shaft 801 of the lifting mechanism 8: when the turntable 602 rotates to the positioning piece 601 and the top shaft 801 are aligned vertically, the top shaft 801 can smoothly pass through the opening 608 to push the bottom of the positioning piece 605, ensuring that the lifting force can be effectively transmitted to the positioning piece 601 and the stator 3, and avoiding the turntable 602 blocking the lifting action.

[0052] The detection mechanism 1 includes a fixed drive cylinder 101, a connecting plate 102, a positioning plate 103, a first positioning rod 104, a second positioning rod 105, and a displacement sensor 106. The piston rod of the drive cylinder 101 is fixedly connected to the connecting plate 102. The positioning plate 103 is connected to the connecting plate 102 and is located below the connecting plate 102. The first positioning rod 104 and the second positioning rod 105 have different lengths and are arranged opposite to each other on both sides of the positioning plate 103. The displacement sensor 106 is disposed on the side between the connecting plate 102 and the positioning plate 103; The positioning plate 103 is provided with a measurement clearance hole 108 corresponding to the telescopic measuring end 107 of the displacement sensor 106; A vertically arranged connecting plate is provided between the connecting plate 102 and the positioning plate 103, and the displacement sensor 106 is fixed on the connecting plate. A drive cylinder 101 is fixed to the upper part of a cylinder mounting base. The piston rod of the drive cylinder 101 passes through the cylinder mounting base and is fixedly connected to the connecting plate 102. The connecting plate 102 and the cylinder mounting base are connected in series via a guide post. When the connecting plate 102 moves up and down, it moves up and down along the guide post. One end of the guide post is fixedly connected to the connecting plate 102. The cylinder mounting base is provided with a guide sleeve that mates with the guide post. When the connecting plate 102 and the cylinder mounting base are connected in series, the guide post is inserted into the guide sleeve.

[0053] When the stator 3 is being measured, the piston rod of the drive cylinder 101 drives the first positioning rod 104, the second positioning rod 105 and the displacement sensor 106 to move toward the stator 3. When the positioning plate 103 and the second positioning rod 105 have both moved to abut against the upper part of the stator 3 and the first positioning rod 104 has moved to abut against the upper part of the positioning fixture 601, the telescopic measuring end 107 of the displacement sensor 106 extends out and abuts against the upper part of the stator 3.

[0054] The drive cylinder 101 drives the connecting plate 102, positioning plate 103, first positioning rod 104, second positioning rod 105, and displacement sensor 106 to move synchronously toward the stator 3, realizing full automation of the detection action. The first positioning rod 104 and the second positioning rod 105 are of different lengths and are set opposite each other to establish a reference positioning. During detection, the first positioning rod 104 abuts against the upper part of the positioning fixture 601 to first determine the reference position of the positioning fixture 601. The second positioning rod 105 abuts against the upper part of the stator 3, and the detection reference of the stator 3 is indirectly calibrated with reference to the reference of the positioning fixture 601. The displacement sensor 106 directly measures the height of the stator 3, and the measurement clearance hole 108 provides unobstructed contact space for its telescopic measuring end 107.

[0055] Specifically, the positioning fixture 601 also includes a support member 610 fixed on the upper part of the connector 604. The support member 610 is used to support the bottom of the stator 3. When the stator 3 is being measured, the first positioning rod 104 abuts against the top surface of the support member 610.

[0057] The folding assembly of the paper feeding device 501 works in conjunction with the paper feeding roller assembly to achieve "pre-processing + stable conveying" of the insulating paper. The folding fixing plate 5016, the folding fixing block 5017, and the folding rolling element 5018 pre-fold the insulating paper during the conveying process, so that the insulating paper forms creases close to the shape of the stator groove 3 in advance. The through slot 5022 of the guide positioning plate 5021 guides the insulating paper to be conveyed along a preset path. The first roller 5012 and the second roller 5013 of the paper feeding roller assembly form a conveying gap, which can clamp the insulating paper and convey it at a uniform speed. The paper feeding motor 5023 drives the rollers to rotate, realizing the conveying of the insulating paper.

[0061] The indexing plate motor 507 drives the indexing plate 506 to rotate in a step-by-step manner through the drive gear and transmission gear 508. The rotation angle can be precisely adjusted according to the number of slots and the slot spacing of the stator 3, so that each slot of the stator 3 is aligned with the paper insertion outlet of the forming device 503 in sequence, ensuring that the insulating paper can be accurately inserted into each slot, avoiding missed insertion, incorrect insertion, or paper misalignment, and improving the integrity and accuracy of paper insertion.

The second transmission gear 903 drives the cutter 5026 to cut the insulating paper through the paper cutting cam 5053 and the connecting rod 5051. At the same time, the first transmission gear 902 drives the push rod 5042 to move up and down through the swing arm 5044, pushing the formed insulating paper into the stator 3 slot.
