DETAILED DESCRIPTION

[0041] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0042] The following describes an embodiment of the present invention based on its overall structure.

[0043] A winding and wiring device for a motor coil and a method of use, such as Figure 1-11 As shown, the device includes a driving device 1 and a workbench 2. A lifting platform 3 is arranged in front of the driving device 1. The driving device 1 is a prior art, and it only needs to drive the lifting platform 3 to move up and down quickly.

[0044] A pad 5 is fixed on the top of the workbench 2, and the top of the pad 5 is rotatably connected to a turntable 6 through a bearing 9. A first motor 10 is installed inside the pad 5, and the output end of the first motor 10 is connected to a first gear 11. The outer side of the turntable 6 is provided with a tooth path that matches the first gear 11, and the bottom of the turntable 6 is also connected to a mounting block 12. Two female clamping blocks 13 are fixed on the inner side of the mounting block 12, and two sub-clamping blocks 14 are provided on the other side of the female clamping block 13. Two clamping cylinders 16 that respectively drive the two sub-clamping blocks 14 to move are also installed on the outer side of the mounting block 12. A wire receiving groove 15 is formed between the sub-clamping blocks 14 and the female clamping blocks 13. Cutting blocks 17 are provided on the inner sides of the two sub-clamping blocks 14 that lean against each other. Slide rails 19 are provided at both ends of the sub-clamping blocks 14 and the female clamping blocks 13, and a wire twisting block 20 is rotatably connected to the slide rails 19. A plurality of guide wheels 18 are rotatably connected and surround the wire twisting block 20 to ensure the smooth rotation of the wire twisting block 20. A wire twisting groove 21 cooperating with the wire receiving groove 15 is provided on the wire twisting block 20. A second motor 24 is installed at both ends of the female clamping block 13. The output end of the second motor 24 is connected to a second gear 23. A tooth path is provided on the outside of the wire twisting block 20, and a transmission gear 22 is provided between the second gear 23 and the wire twisting block 20 for transmission. A clamp 7 is fixed on the top of the turntable 6, and a fixed frame 4 is fixed in front of the lifting platform 3. Three lead rods 25 are connected to the bottom of the fixed frame 4. The bottom ends of the three lead rods 25 are all connected to an outer tube 33. One end of the outer tube 33 is telescopically connected to a telescopic rod 30. Three groups of positioning cylinders 8 are installed on the outside of the clamp 7. The output end of the positioning cylinder 8 movably passes through the inner side of the clamp 7.

[0045] When in use, the stator core is placed inside the fixture 7. Since the inner diameter of the turntable 6 is smaller than that of the fixture 7, the turntable 6 can support the placed stator core, and then the positioning cylinder 8 is controlled to extend to fix the stator core inside the fixture 7. The lead rods 25, the outer tube 33 and the telescopic rod 30 are all provided with wire grooves 28 that are interconnected. The end of the telescopic rod 30 is provided with a wire hole 32 that is connected to the wire groove 28. The copper wire is inserted into the wire groove 28 in advance and passed out from the wire hole 32. The three lead rods 25 are distributed at a 120-degree angle, so that the three copper wires that are passed out are also distributed at a 120-degree angle. In this embodiment, taking the stator core with nine coils as an example, every three The coils form a group, and there are three groups in total. The lead rod 25 is lowered to the middle of the stator core through the lifting platform 3. First, the first motor 10 drives the first gear 11 to rotate once, the first gear 11 drives the turntable 6 to rotate, the turntable 6 drives the mounting block 12 to rotate, and the mounting block 12 drives the mother clamping block 13 and the sub-clamping block 14 to rotate one circle, so that the three wire ends are collected through the wire collection groove 15. The front end of the wire collection groove 15 has a flared structure, which is convenient for guiding the copper wire in. After the three copper wires are collected, the clamping cylinder 16 controls the sub-clamping block 14 to cooperate with the mother clamping block 13 to clamp the three wire ends. When the wire ends are clamped in the wire collection groove 15, they are also located between the wire twisting grooves 21 at the same time. The second motor 24 drives the first gear 11 to rotate once, and the first gear 11 drives the turntable 6 to rotate. The turntable 6 drives the mounting block 12 to rotate. The mounting block 12 drives the mother clamping block 13 and the sub-clamping block 14 to rotate one circle. The second gear 23 rotates multiple times, and the second gear 23 drives the wire twisting block 20 to rotate multiple times through the transmission gear 22, so that the three wire ends can be twisted together to obtain a bus end, and then the lifting platform 3 drives the lead rod 25 to reciprocate up and down through the fixed frame 4. At the same time, the first motor 10 drives the turntable 6 to rotate back and forth left and right through the first gear 11, so that the turntable 6 drives the clamp 7 and the stator core to rotate back and forth for a short distance left and right, so that the copper wire can be wound on the winding pile of the stator core, and a group of coils can be wound at the same time. When a group of three coils are wound, the first motor 10 is used to drive the clamp 7 and the stator core to rotate 120 degrees, and the next group of coils is carried out according to the above steps. Winding is carried out until all three groups of coils are wound, and then the clamping cylinder 16 controls one group of mother-and-child clamps to open, and the first motor 10 drives the mother clamp 13 and the child clamp 14 to rotate one circle, so that the three wire tails are collected through the wire collection groove 15, and then the second motor 24 drives the wire twisting block 20 to rotate multiple circles, so that the three wire tails can be twisted together again to obtain a bus tail, which is convenient for subsequent wiring work. After twisting together, the clamping cylinder 16 further tightens the child clamp 14, and uses the cutting block 17 to cut the copper wire, and then loosens the child clamp 14 to complete the winding work of a stator core, loosen the positioning cylinder 8, take the stator core out of the clamp 7, and send it to the next step for wiring.

[0046] In order to ensure that the wires are neatly arranged, the telescopic rod 30 is in a reciprocating telescopic state during the winding process. Fig.11Specifically, there is an air cavity 31 between the outer tube 33 and the telescopic rod 30, and an air groove 26 is provided on the inner side of the lead rod 25. When the three lead rods 25 are assembled, the three air grooves 26 together form a channel. An air passage 29 for connecting the air cavity 31 and the channel is provided inside the outer tube 33. A vent pipe 27 connected to the channel is provided on the top of the fixing frame 4. The vent pipe 27 is connected to the external control air circuit. When the gas enters the air cavity 31, the telescopic rod 30 is pushed out by air pressure. When the gas in the air cavity 31 is drawn away, the telescopic rod 30 will retract again under the action of negative pressure, thereby controlling the telescopic rod 30 to reciprocate, and then controlling the wire hole 32 to reciprocate back and forth, so that the copper wires wound on the stator core winding piles are arranged neatly.

The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the present invention.
