[0040] The connecting mechanism is located on one side of the turntable 2 and is used to cut the wound wire and connect the remaining wire to the next winding assembly;

[0041] The interior of the turntable 2 is a hollow structure, and there are three winding assemblies. One end of each of the three driving sleeves 3 extends to the interior of the turntable 2. The winding mechanism also includes three transmission wheels respectively sleeved on the outside of the three driving sleeves 3, belts connected to the outside of the three transmission wheels, and a motor 5 installed inside the turntable 2.

[0042] The fixing mechanism includes a first screw 6 fixedly connected to the inner wall of the driving sleeve 3 on the side close to the turntable 2, a first screw sleeve 7 screwed on the outside of the first screw 6, a first bevel gear 8 arranged on the outside of the first screw sleeve 7, a driving block 9 rotatably connected to one end of the first screw sleeve 7, and four positioning blocks 10 radially slidably connected to the inner wall of the driving sleeve 3, the outer walls of the four positioning blocks 10 away from the driving block 9 extend to the outside of the driving sleeve 3, the outer walls of the four positioning blocks 10 on the side close to the driving block 9 are provided with driven grooves of a right-angled triangular structure, the outer wall of the driving block 9 on the side close to the positioning block 10 is provided with four driving grooves corresponding to the four driven grooves, the driving groove is a right-angled triangular structure, and the interior of the driving block 9 is provided with a sliding groove along the axial direction of the first screw sleeve 7. , a fixing strip 11 is slidably connected inside the slide groove, one end of the fixing strip 11 extends to the outside of the slide groove and is fixedly connected to the inner wall of the driving sleeve 3. The fixing mechanism also includes a transmission assembly for driving the first screw sleeve 7 to rotate. When the first screw sleeve 7 is driven by the transmission assembly to move toward one side of the fixing strip 11, the four driving grooves on the driving block 9 cooperate with the driven grooves on the four positioning blocks 10 to drive the four positioning blocks 10 to move outward synchronously, thereby automatically fixing the reel 4 to the outside of the driving sleeve 3. In addition, through the cooperation of various components of the fixing assembly, the first screw sleeve 7 is driven to move along the outer wall of the first screw rod 6 in a direction away from the fixing strip 11, thereby driving the driving block 9 to break away from the contact with the four positioning blocks 10, and the fixation of the reel 4 can be automatically released;

[0043] The outside of the first screw sleeve 7 is fixedly connected with a key pin 12 in the axial direction, and the outside of the first screw sleeve 7 is provided with a vertical plate fixedly connected to the inner wall of the driving sleeve 3. The first bevel gear 8 is rotatably connected to the outer wall of the vertical plate. The inside of the first bevel gear 8 is provided with a key slot in the axial direction.

The first bevel gear 8 rotates in situ and drives the first screw sleeve 7 to rotate and move at the same time through the key pin 12 cooperating with the key slot;

[0044] A first tooth arc 13 and a second tooth arc 14 are fixedly connected to the outer wall of the fixed seat 1. The first tooth arc 13 and the second tooth arc 14 are symmetrically arranged on both sides of the turntable 2, and the tooth grooves of the first tooth arc 13 and the tooth grooves of the second tooth arc 14 are arranged opposite to each other. The transmission assembly includes a first transmission shaft 16 connected to the inner wall of the driving sleeve 3 in a radial direction, a second bevel gear 17 fixedly connected to one end of the first transmission shaft 16, and a first gear 18 fixedly connected to the first transmission shaft 16 and extending to one end of the outside of the driving sleeve 3. The first gear 18 cooperates with the first tooth arc 13 and the second tooth arc 14 respectively, and the first bevel gear 8 and the second bevel gear 17 are arranged opposite to each other. When the first gear 18 is meshed with the first tooth arc 13, the first transmission shaft 16 is driven to rotate, and the first screw sleeve 7 is driven to rotate through the meshing of the second bevel gear 17 and the first bevel gear 8, thereby driving the first screw sleeve 7 to move along the outer wall of the first screw rod 6 toward the side of the fixed bar 11. When the first gear 18 rotates to mesh with the second tooth arc 14, the first transmission shaft 16 is driven to rotate in the opposite direction, thereby driving the first screw sleeve 7 to move along the outer wall of the first screw rod 6 away from the fixed bar 11.

[0045] A connecting block is fixedly connected to the outer wall of the positioning block 10 away from the first screw rod 6, and a limiting rod fixed to the inner wall of the driving sleeve 3 is radially slidably connected inside the connecting block along the driving sleeve 3. A third spring is sleeved on the outside of the limiting rod, one end of the third spring is fixedly connected to the inner wall of the driving sleeve 3, and the other end of the third spring is fixedly connected to the outer wall of the connecting block. A first limiting ring is fixedly connected to the other end of the limiting rod, and the first limiting ring is provided to limit the position of the positioning block 10 moving inwardly. A second limiting ring is sleeved on the outside of the driving sleeve 3, and the second limiting ring is provided to limit the position of the reel 4 on the driving sleeve 3. When the positioning block 10 moves outward, it drives the connecting block to move along the outside of the limiting rod, and the third spring contracts accordingly. When the positioning block 10 loses the driving force, the rebound force of the third spring drives the positioning block 10 to reset.

[0046] The connecting mechanism includes a fixed plate installed on the outer wall of the fixed base 1, a second screw sleeve 19 rotatably connected to the outer wall of the fixed plate near the rotating disk 2, a second screw rod 20 screwed inside the second screw sleeve 19, a clamping block 21 fixedly connected to the second screw rod 20 and extending to one end of the outside of the second screw sleeve 19, and a cutting knife 22 fixedly connected to the bottom of the clamping block 21, the clamping block 21 is an arc-shaped structure and cooperates with the reel 4, a telescopic rod is also fixedly connected to the outer wall of the fixed plate, and the other end of the telescopic rod is fixedly connected to the outer wall of the clamping block 21, the connecting mechanism also includes a gear ring 23 sleeved on the outside of the rotating disk 2, a second transmission shaft 24 rotatably connected to the outer wall of the fixed base 1, a second gear 25 sleeved on the outside of the second transmission shaft 24, a third bevel gear 26 fixedly connected to the other end of the second transmission shaft 24 and two fourth bevel gears 27 sleeved on the outside of the second screw sleeve 19, the second gear 25 meshes with the gear ring 23, the third bevel gear 26 is a semi-bevel gear, and the third bevel gear 27 is a semi-bevel gear. The gear 26 is located between the two fourth bevel gears 27 and cooperates with the two fourth bevel gears 27 respectively. The connecting mechanism also includes a fixing assembly arranged on the reel 4 and cooperated with the abutting block 21. When the turntable 2 rotates, the gear ring 23 is driven to rotate synchronously. Through the meshing effect of the gear ring 23 and the second gear 25, the second transmission shaft 24 is driven to rotate, thereby driving the third bevel gear 26 to rotate. At this time, the third bevel gear 26 is only meshed with one of the fourth bevel gears 27, thereby driving the second screw sleeve 19 to rotate forward, thereby driving the second screw rod 20 away from the reel 4, and the abutting block 21 moves accordingly. When the turntable 2 continues to rotate, it will drive the third bevel gear 26 to mesh with the other fourth bevel gear 27, thereby driving the second screw sleeve 19 to rotate in the opposite direction, thereby driving the second screw rod 20 and the abutting block 21 close to the reel 4, thereby driving the cutting knife 22 to cut the wire, and at the same time, the wire is fixed on the reel 4 through the fixing assembly;

[0047] The fixing assembly includes two clamping parts symmetrically arranged at both ends of the reel 4, the clamping parts include a fixing groove opened at one end of the reel 4, a slide bar 28 radially fixed to the inner wall of the fixing groove, a clamping block 29 slidably connected to the outside of the slide bar 28, and a first spring 30 sleeved on the outside of the slide bar 28, one end of the first spring 30 is fixed to the outer wall of the clamping block 29, the fixing groove is an L-shaped structure, the other end of the first spring 30 is fixed to the inner wall of the fixing groove, and the end of the clamping block 29 extending to the outside of the fixing groove is provided with an inclined groove of a right-angled triangle structure. The setting of the inclined groove can enable the wire to slide along the inclined groove to the surface of the reel 4 when it is placed on the top of the clamping block 29, and through the limiting effect of the guide ring 34, the wire is returned to the bottom of the clamping block 29. The setting of the first spring 30 can prevent the clamping block 29 from being affected by the wire and moving downward excessively through its rebound force. The clamping parts also include two movable grooves symmetrically opened on both sides of the fixing groove, respectively slidably connected to the two movable grooves. The two limit blocks 31 inside the groove and the two second springs 32 respectively fixed on the outer wall of the side away from the two limit blocks 31, the other ends of the two second springs 32 are respectively fixed to the inner walls of the two movable grooves, and the two limit blocks 31 are extended to the ends of the fixed grooves. Both ends are provided with a force-bearing groove of a right-angled triangle structure. When the clamping block 21 moves toward the winding drum 4, the clamping block 21 will abut against the clamping block 29, thereby driving the clamping block 29 to move along the outer wall of the slide bar 28, thereby driving the clamping block 29 to clamp the wire inside the fixed groove. At the moment when the clamping block 29 clamps the wire inside the fixed groove, the cutting knife 22 on the clamping block 21 cuts the wire. At the same time, in this process, when the clamping block 29 abuts against the force-bearing grooves on the two limit blocks 31, the two limit blocks 31 move to the inside of their respective movable grooves. When the clamping block 29 passes through the position of the limit block 31, the two limit blocks 31 are driven to clamp the clamping block 29 through the rebound force of the two second springs 32.

[0048] The implementation principle of a high-efficiency motor winding splicing device in Example 1 of the present application is as follows: first, the staff places the reel 4 outside the driving sleeve 3 at the lower left, and manually fixes one end of the wire inside the fixed groove on the reel 4, and then drives the turntable 2 to rotate one-third of a circle through the servo motor. In this process, the driving sleeve 3 is driven to perform orbital motion. When the first gear 18 is engaged with the first tooth arc 13, the first transmission shaft 16 is driven to rotate, and the first screw sleeve 7 is driven to rotate through the engagement of the second bevel gear 17 with the first bevel gear 8, thereby driving the first screw sleeve 7 to rotate, thereby driving the first screw sleeve 7 to move along the outer wall of the first screw rod 6 toward the side of the fixed strip 11, and driving the four positioning blocks 10 through the cooperation of the four driving grooves on the driving block 9 and the driven grooves on the four positioning blocks 10. 10 moves outward synchronously, thereby automatically fixing the reel 4 on the outside of the driving sleeve 3. At this time, the driving sleeve 3 is driven to rotate by starting the motor 5, and then the reel 4 is driven to rotate synchronously, so that the wire is wound around the outside of the reel 4. Then the servo motor drives the turntable 2 to continue to rotate one-third of a circle. During this process, the reel 4 directly above will rotate to the lower right, and the reel 4 on the lower left will rotate to the top. At the same time, the wire will be placed on the reel 4 that has just rotated to the top. In addition, in this process, the turntable 2 drives the gear ring 23 to rotate synchronously during the process of rotating one-sixth of a circle. Through the meshing effect of the gear ring 23 and the second gear 25, the second transmission shaft 24 is driven to rotate half a circle, thereby driving the third bevel gear 26 to rotate. At this time, the third bevel gear 2 6 is meshed with one of the fourth bevel gears 27, thereby driving the second screw sleeve 19 to rotate forward, thereby driving the second screw rod 20 and the clamping block 21 to move away from the reel 4 first, so as not to affect the revolution of the reel 4. In the process of rotating the remaining one-sixth of a circle, the turntable 2 drives the second transmission shaft 24 to continue to rotate half a circle, thereby driving the third bevel gear 26 to mesh with the other fourth bevel gear 27, thereby driving the second screw sleeve 19 to rotate in the opposite direction, thereby driving the second screw rod 20 and the clamping block 21 to approach the reel 4, thereby driving the cutting knife 22 to cut the wire. At the same time, when the clamping block 21 moves toward the reel 4, the clamping block 21 will abut against the block 29, thereby driving the block 29 to move along the outer wall of the slide bar 28, thereby driving the block 2 9 clamps the wire inside the fixed groove. At the moment when the clamping block 29 clamps the wire inside the fixed groove, the cutting knife 22 on the clamping block 21 cuts the wire. At the same time, in this process, when the clamping block 29 abuts against the force-bearing grooves on the two limit blocks 31, the two limit blocks 31 move to the inside of their respective movable grooves. When the clamping block 29 passes through the position of the limit blocks 31, the rebound force of the two second springs 32 drives the two limit blocks 31 to clamp the clamping block 29, and then the motor 5 continues to drive the reel 4 to rotate, thereby continuing to wind the wire around the outside of the reel 4. In this way, the wire can be wound around each reel in a cycle and can be automatically connected. No manual participation is required during the continuous winding process, which effectively improves the winding efficiency of the motor coil.

When the wire needs to be wound around the next reel 4, the motor 5 is controlled to reverse, thereby driving the drive sleeve 3 and the reel 4 to reverse, thereby driving the lead screw 33 to reverse through the two third gears 36, and then driving the wire to be gradually and evenly wound around the outside of the reel 4 through the guide ring 34 and the annular groove 35, and the cycle is repeated in sequence, and the motor 5 is controlled to reciprocate forward and reverse, and the number of forward and reverse turns is the same, so that the wire can always be evenly wound around the outside of the reel 4.
