[0002] Motor enameled wire is a special copper wire with a layer of insulating enameled layer on its surface. This structure makes the enameled wire have both the good conductivity of copper wire and the electrical insulation performance of the insulating layer. The enameled wire is mainly composed of two parts: the conductor and the insulating layer, and is mainly used as the winding wire of the motor.

[0003] When winding the enameled wire, the operator is required to wind the enameled wire on a winding mold. The winding mold is provided with multiple slots. The enameled wire wound in a single slot is a group. The number of enameled wires in each group needs to be the same. Therefore, the enameled wires in a single group need to be bundled to prevent the problem of line disorder when the coil is subsequently installed in the motor. The existing winding method is that the operator rotates the winding mold, and when the number of coils in a single slot reaches the requirement, the enameled wire is guided to the next slot.

[0040] The clamping jaw assembly 24 includes a base 32, an electric clamping jaw 1 33 and an electric clamping jaw 2 34. The electric clamping jaw 1 33 and the electric clamping jaw 2 34 are both arranged on the base 32. The base 32 is slidably arranged in the through hole 31. The through hole 31 limits the freedom of the base 32 in other directions. A T-slot 35 is provided at the tail of the base 32.

The rotating motor 41 is fixedly arranged on the discharge hook 22, and the hot pressing plate 42 is fixedly arranged at the output end of the rotating motor 41. An electric heating plate is also arranged on the hot pressing plate 42.

[0042] When winding is required in a certain winding groove 7, the base 32 is first driven by the telescopic electric cylinder 23 to move toward the discharge hook 22 so that the electric clamp 1 33 clamps the strapping tape 91, and then the base 32 is retracted to pull out the strapping tape 91, and then the second linear slide 20 drives the strap base plate 21 to move so that the coil 90 enters the inner side of the discharge hook 22. At this time, the strapping tape 91 follows the coil 90 into the inner side of the discharge hook 22 and is wrapped around the outer side of the coil 90. The telescopic electric cylinder 23 is driven to move so that the electric clamp 2 34 clamps the strapping tape 91, and then the blade 40 cuts off the strapping tape 91. At this time, a part of the strapping tape 91 is still exposed at the discharge port 50 of the discharge hook 22, and the two ends of the strapping tape 91 are separated. The first and second electric clamps 33 and 34 are fixed on them respectively, and then the base 32 is moved to the rotating motor 29 through the third linear slide 28, so that the T-block 2 37 is engaged with the T-slot 35, and the rotating motor 2 41 rotates the base 32, so that the strapping belt 91 is gradually twisted together, and at the same time, the second linear slide 20 drives the strap base plate 21 to move slightly toward the coil 90 as a whole to prevent the strapping belt 91 from breaking after shortening. After the strapping belt 91 tightens the coil 90, the second linear slide 20 drives the hot pressing plate 42 to move to the corresponding position. At this time, the rotating motor 2 41 rotates the hot pressing plate 42 to hot-melt and fix the twisted position of the strapping belt 91, thereby completing the bundling of the coil 90.

The locking rod 43 is pressed against the side wall of the straight groove 46, and the other end is pressed against the screw 48, so that when the telescopic electric cylinder 23 pushes out the clamping jaw assembly 24, the locking rod 43 will always be in the second locking hole 45. When the telescopic electric cylinder 23 retracts, the locking rod 43 can also be pressed against the second locking hole 45 by the pressure of the spring 49 to prevent the base 32 from being separated from the T-block 1 36 due to vibration or the like. When the base 32 needs to be moved, the telescopic electric cylinder 23 continues to retract, so that the locking rod 43 compresses the spring 49 and is separated from the second locking hole 45.

All technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
