[0024] The clamping mechanism includes two support rods 14 symmetrically fixed in the mounting hole 9. A U-shaped rod 10 is slidably sleeved between the two ends of the two support rods 14. An extension block 16 is provided at the end of each of the two U-shaped rods 10. A clamping wheel 13 is rotatably mounted between the two extension blocks 16 of the two U-shaped rods 10 through a bearing. The two support rods 14 are each sleeved with a spring 15 at the position between the U-shaped rod 10 and the inner wall of the mounting hole 9.

[0025] The wire-digging mechanism includes a fixed plate 8 fixed to the top of the vertical section on one side of the U-shaped seat 1, a threaded rod 18 is rotatably mounted on the upper end surface of the horizontal section of the U-shaped seat 1 through a bearing, a first servo motor 7 is mounted on the upper end surface of the fixed plate 8, the output end of the first servo motor 7 is connected to the upper end of the threaded rod 18, a moving block 17 is screwed onto the threaded rod 18, a guide rod 21 is fixed between the fixed plate 8 and the horizontal section of the U-shaped seat 1, the moving block 17 is slidably sleeved on the guide rod 21, a U-shaped block 19 is fixed to one end of the moving block 17, and a wire-digging ring 20 is fixed to the inner side of the U-shaped block 19;

[0026] The rotating mechanism includes a second servo motor 2 fixed to the upper end surface of the horizontal section of the U-shaped base 1. The output end of the second servo motor 2 is connected to the rotating base 3. The upper end surface of the rotating base 3 is provided with a mounting groove 4.

[0027] The coil bobbin fixing assembly includes a bidirectional screw 6 rotatably mounted in the mounting slot 4 via a bearing. Both ends of the bidirectional screw 6 are screwed with L-shaped clamping rods 5. The bottoms of the two L-shaped clamping rods 5 are slidably engaged with the mounting slot 4. One end of the bidirectional screw 6 extends to the outside of the rotating base 3 and is connected to a knob.

[0028] The wire coil support assembly includes an L-shaped support plate 12 fixed on the outer wall of the vertical section of one side of the U-shaped seat 1 and located in the mounting hole 9.

[0029] Working principle: Put the coil skeleton on the outside of the two L-shaped clamping rods 5, and turn the bidirectional screw 6 through the knob to move the two L-shaped clamping rods 5 in opposite directions, thereby fixing the coil skeleton, and wrap the copper wire around the support pin 11, and pass the copper wire between the two clamping wheels 13, and then pass it through the wire dialing ring 20, and then connect one end of the copper wire to the coil skeleton, turn on the second servo motor 2, so that the second servo motor 2 drives the rotating seat 3 to rotate, and then the coil skeleton rotates.

On the skeleton, since the copper wire is clamped by two clamping wheels 13, and the two support rods 14 are located on one side of the two U-shaped rods 10 and are both covered with springs 15, the rebound force provided by the springs 15 increases the clamping force of the clamping wheels 13 on the two U-shaped rods 10, and then the copper wire between the two holding wheels 13 and the coil skeleton is kept in a taut state, ensuring that the coil wound on the skeleton is tight and orderly, avoiding the fluffy situation to a large extent, and ensuring that the coil can be used normally, and the servo systems of the first servo motor 7 and the second servo motor 2 are used to control the operation of the first servo motor 7 and the second servo motor 2 respectively, so that the output shafts of the first servo motor 7 and the second servo motor 2 rotate a fixed number of circles, which can realize quantitative winding of the coil.
