[0027] like Figures 1-7 As shown, the multifunctional welding device for new energy motor production includes a frame 1, on which is mounted a translation rail 2, a sliding mounting plate 3 mounted on the translation rail 2. The sliding mounting plate 3 is driven by a translation drive mechanism to move on the translation rail 2. The sliding mounting plate 3 is mounted on the translation rail 2. The iron core welding tool 4 and the winding dividing tool 5 are mounted on the sliding mounting plate 3. The translation rail 2 is accompanied by a laser welding mechanism 6 and a wire end trimming mechanism. The translation drive mechanism can be a combination of a motor and a screw rod, a cylinder, or a linear motor, or other commonly used drive mechanisms capable of achieving linear displacement drive.

[0028] The laser welding mechanism 6 includes a welding head 7, and the welding head 7 is located above the translation slide rail 2. The laser welding mechanism 6 is an existing laser welding device.

[0029] The iron core welding tool 4 comprises a laminating tool, a rotating block 8 and a rotating drive motor 9. The laminating tool comprises a laminating tray 10 and a pressing cover 53. The lower surface of the laminating tray 10 is fixedly connected with a rotating shaft 11 in the middle. The upper surface of the laminating tray 10 is fixedly connected with a center column 12 in the middle. The upper end of the center column 12 is provided with a connecting clamping groove 13. The middle of the pressing cover 53 is provided with a center hole through which the center column 12 passes. The center column 12 is provided with a threaded section. The threaded section is threadedly connected with a pressing plate 54. The output shaft of the rotating drive motor 9 is fixedly connected with a connecting rotating plate 14. The connecting rotating plate 14 is fixedly connected with a connecting clamping block 15 for inserting into the connecting clamping groove 13.

The just laminated iron core is pressed by the pressing cover 53 and the laminating tray 10 and locked by the pressing plate 54. The rotating shaft 11 is inserted into the rotating insertion hole. The rotating shaft 11 is rotated so that the center column 12 is in a horizontal state and the connecting clamping block 15 is inserted into the connecting clamping groove 13. Thus, the iron core can be rotated by the rotating drive motor 9. After the iron core moves below the welding head 7, the laser welding mechanism 6 welds the outer side of the iron core in cooperation with the movement of the sliding installation plate 3. After one welding is completed, the iron core is rotated by a certain angle to weld another position. In order to make the iron core rotate better in a horizontal state, support blocks can be arranged on both sides of the output shaft of the rotating drive motor 9. Support wheels are installed on the support blocks. The center column 12 is just placed between the two support wheels. Bearings are arranged in the rotating insertion hole.

[0030] The winding division tool 5 comprises an iron core tray 16 rotatably installed on the sliding installation plate 3. The iron core tray 16 is driven to rotate by a division motor 17 installed on the sliding installation plate 3. The wire-inserted motor stator iron core is placed on the iron core tray 16. The motor stator iron core is moved below the welding head 7 by the movement of the sliding installation plate 3. The winding wire head is welded by the division motor 17.

[0031] The wire head end cutting mechanism comprises a cutting knife 18 driven to move by a pushing mechanism 19. The motor stator iron core sleeved with the welding tool is moved to the wire head end cutting mechanism by moving the sliding installation plate 3. Then the pushing mechanism 19 drives the cutting knife 18 to move to cut the heads of a group of wire heads. After cutting, the cutting knife 18 retreats. The division motor 17 drives the motor stator iron core to rotate by a certain angle. The cutting knife 18 cuts the heads of the next group of wire heads. The above steps are repeated until all the wire heads are cut. After the cutting of the heads is completed, the sliding installation plate 3 moves so that the motor stator iron core moves below the welding head 7. The wire heads are welded in turn by the division motor 17. The pushing mechanism 19 can be a cylinder or a linear motor.

[0032] Further, the frame body 1 is provided with an iron core stacking assembly 20, which comprises a mounting turntable 21, and the middle part of the mounting turntable 21 is provided with a central slot for inserting the rotating shaft 11. Artificial or mechanical hands stack the iron core pieces on the mounting turntable 21 beside the frame body 1.

[0033] Further, the frame body 1 is provided with an installation port 22, the mounting turntable 21 is rotatably installed in the installation port 22, a lifting plate 23 is arranged below the installation port 22, the lifting plate 23 is driven to move vertically by a vertical driving mechanism 24, the lifting plate 23 is provided with a through hole, a transmission shaft 60 is movably installed in the through hole, the upper end of the transmission shaft 60 is fixedly connected to the middle part of the lower surface of the mounting turntable 21, a linkage wheel is movably sleeved on the transmission shaft, the linkage wheel is fixedly connected with a linkage turntable 25, the transmission shaft is provided with a key groove, a connecting key is fixedly arranged on the linkage wheel, the connecting key is slidably inserted into the key groove, the linkage wheel is driven to rotate by a linkage rotary driving mechanism 26, and the linkage turntable 25 is fixedly connected with a plurality of positioning insertion plates 27. The stacking tray 10 is provided with a plurality of positioning ports for respectively inserting the positioning insertion plates 27. The iron core is composed of a plurality of iron core pieces, the iron core pieces are uniformly processed, and the processed iron core pieces may have a situation that one side is thicker and the other side is thinner. Although the error is very small, when a large number of iron core pieces are stacked together in the same state, the error will be magnified. In order to eliminate the influence of the error, the iron core pieces need to be stacked in the opposite direction after a certain number of iron core pieces are stacked. In this way, the iron core is divided into a plurality of layers of iron core pieces. In order to achieve this effect, the outer side of the iron core piece is provided with a positioning notch, and the positioning notches of each layer of iron core pieces are connected to form a straight slot, and the positions of the straight slots of different layers of iron core pieces are different. The iron core piece is provided with a process groove for inserting wires. During the process of placing the iron core piece, the vertical driving mechanism 24 drives the lifting plate 23 to continuously rise, and drives the positioning insertion plates 27 to continuously rise. The positioning insertion plates 27 are respectively inserted into the process grooves 51 of the iron core pieces, and the iron core pieces are preliminarily positioned. After one layer of iron core pieces is placed, the positioning insertion plates 27 stop rising, the linkage rotary driving mechanism 26 drives the linkage wheel to rotate by a certain angle, and then the iron core pieces are continuously stacked in the same posture. At the same time, the positioning insertion plates 27 resume rising. The above steps are repeated until the plurality of layers of iron core pieces are stacked. The positioning insertion plates 27 are lowered and withdrawn from the positioning ports of the stacking tray 10. The vertical driving mechanism 24 can be a pneumatic cylinder or a linear motor, or a motor and a lead screw mechanism, etc. which can realize linear displacement. The linkage rotary driving mechanism 26 is a motor.

[0034] Further, the lifting plate 23 is connected with a follow-up beam 28, the two ends of the follow-up beam 28 are fixedly connected with the lifting plate 23 through guide rods 29, the follow-up beam 28 is located above the frame body 1, the follow-up beam 28 is installed with a positioning insert 30 vertically pointing to the axis of the laminated tray 10, the positioning insert 30 is driven to move by a linear movement driving mechanism 31. When the laminating of the iron core pieces of a layer is carried out, the linear movement driving mechanism 31 drives the positioning insert 30 to extend, and then the positioning notch on the placed iron core piece needs to correspond to the positioning insert 30, that is, the positioning insert 30 needs to extend into the positioning notch. With the continuous placement of the iron core pieces, the lifting plate 23 rises, driving the follow-up beam 28 to rise, and then the positioning insert 30 also gradually rises until the placement of the iron core pieces of the layer is completed, and the positioning insert 30 retreats. In this way, the positioning notches of the iron core pieces of the same layer are connected into a vertical straight line slot from bottom to top, so that the laminating process of the iron core pieces meets the design requirements of the iron core. After the installation turntable 21 drives the laminated iron core pieces to rotate by a certain angle, the positioning insert 30 extends again to position the next layer of iron core pieces. The linear movement driving mechanism 31 is a pneumatic cylinder.

After the iron core pieces are laminated, the pressing cover 53 is covered on the iron core, the pressing bolts 37 pass through the pressing holes and the inside of the iron core and are screwed into the pressing screw holes 35, and the iron core pieces are further pressed. At the same time, the fine positioning plates 39 are inserted into the process grooves 51 on the iron core pieces for wire insertion, so that the iron core pieces can be precisely positioned. The fine positioning plates 39 are precisely matched with the process grooves 51 on the iron core pieces to form precise positioning of the iron core pieces.

[0036] One side of the installation turntable 21 is provided with a clamping opening 32, the frame body 1 on one side of the installation opening 22 is provided with a clamping block 33, and the clamping block 33 is driven to be inserted into or withdrawn from the clamping opening 32 by a clamping driving mechanism 34. When the pressing bolts 37 need to be tightened, the clamping driving mechanism 34 drives the clamping block 33 to be inserted into the clamping opening 32, so that the installation turntable 21 can be kept fixed. When the iron core is laminated, the clamping block 33 is withdrawn from the clamping opening 32, and the installation turntable 21 can be driven to rotate by the linkage rotary driving mechanism 26. The clamping driving mechanism 34 is a pneumatic cylinder.

The lower surface of the upper layer sliding plate 41 is higher than the uppermost end of the iron core tray 16. When the iron core welding tool 4 is needed to be used, the sliding drive mechanism 42 drives the upper layer sliding plate 41 to move, so that the rotating drive motor 9 is close to the rotating block 8. When the iron core tray 16 is needed to be used to weld the winding wire head of the motor stator iron core, the rotating drive motor 9 is away from the rotating block 8, and the iron core tray 16 is exposed. In this way, the structure of each component on the sliding mounting plate 3 is more compact, the volume of the whole multifunctional welding device is reduced, and the space utilization of the frame body 1 is improved. The sliding drive mechanism 42 can be a cooperation of a motor and a screw rod, or a cylinder, or a linear motor, or other common driving mechanisms that can realize linear displacement driving. A cooperation of a screw rod and a hand wheel can also be adopted to realize manual driving.

[0038] Further, the frame body 1 is mounted with a welding tool placing mechanism 43. The welding tool placing mechanism 43 comprises a lifting plate 44. The lifting plate 44 is driven by a lifting drive mechanism 45 to lift and is driven by a transfer drive mechanism 46 to move. The lifting plate 44 is provided with a gap slot 47 through which the iron core 48 passes. The lifting plate 44 on both sides of the gap slot 47 forms a supporting arm 49. The welding tool is placed on the lifting plate 44, and the two sides of the welding tool are supported by the supporting arm 49. The motor with the inserted wire is transferred to the iron core tray 16, and then the transfer drive mechanism 46 drives the lifting plate 44 to move, so that the welding tool moves to the upper side of the motor. The lifting drive mechanism 45 drives the lifting plate 44 to descend, so that the welding tool is sleeved on the motor stator iron core, and the winding wire head is fixed by the welding tool. Finally, the lifting drive mechanism 45 drives the lifting plate 44 to continue to descend by a distance, and then the transfer drive mechanism 46 drives the lifting plate 44 to retreat. The sliding mounting plate 3 moves, and drives the motor stator iron core with the mounted welding tool to move to the lower side of the welding head 7. The degree motor 17 drives the degree rotation of the iron core tray 16, and the wire head is welded in sequence.
