An installation groove 30534 is arranged on the first rotating head 30532, and a top arm 30535 in L shape is arranged in the installation groove 30534. A through hole is arranged on the part of the first rotating head 30532 located at the installation groove 30534, the through hole communicates the installation groove 30534 with the hollow part of the first sleeve 30531, and the through hole is coaxially arranged with the first sleeve 30531.

Two pull springs 305312 are arranged between the first pull rod 305315 and the second pull rod 305316, which are always in a stretched state to enable the top arm 30535 to always press on the stop block 305311 when the action force of the first top rod 30536 is lost.

[0074] A pulley 30533 is arranged on the first sleeve 30531, and a motor is arranged on the second mounting frame 3052. The motor is in driving connection with the pulley 30533 through a belt, so that the first sleeve 30531 and other structures on the first sleeve 30531 can be driven to rotate by the motor.

The first top block 305317 is driven by a pneumatic cylinder.

[0076] The guiding assembly 306 comprises a support rod 3061 arranged on the frame 1, a third mounting frame 3062 supported on the support rod 3061, a fourth mounting frame 3063 movably supported below the third mounting frame 3062, two second rotating assemblies arranged on the fourth mounting frame 3063, each of the second rotating assemblies comprising a second sleeve 3065 rotatably arranged on the fourth mounting frame 3063, a second rotating head 3066 arranged at a lower end of the second sleeve 3065, and a second top rod 3067 arranged in the second sleeve 3065, the second rotating head 3066 is coaxially arranged with the second sleeve 3065, the second top rod 3067 is coaxially arranged with the second sleeve 3065, an upper end of the second top rod 3067 is arranged to pass through an upper end of the second sleeve 3065, a lower end of the second top rod 3067 is arranged to pass through the second rotating head 3066, and the second top rod 3067 is movable up and down relative to the second sleeve 3065. Distances between axes of the second top rods 3067 of the two second rotating assemblies are equal to a distance between axes of the two first top rods 30536. A diameter of the lower end of the second top rod 3067 is equal to or slightly smaller than an inner diameter of the coil 100.

[0077] When winding is needed, the second top rod 3067 is arranged to extend from the lower end of the second rotating head 3066 by a certain length, the fourth mounting frame 3063 is arranged to move downward, the second mounting frame 3052 is arranged to move upward, and the upper end of the first top rod 30536 is arranged to contact the lower end of the corresponding second top rod 3067. When winding starts, the first rotating assembly 3053 and the second rotating assembly are arranged to rotate in the same direction and at the same speed. Since the wire end of the copper wire is pressed against the stop block 305311 by the pressing block 305310, the wire end of the copper wire will rotate together with the first rotating assembly, and the copper wire can be wound on the part of the second top rod 3067 extending from the second rotating head 3066. During winding, the coil has a certain height in the up-down direction, so the second mounting frame 3052 and the fourth mounting frame 3063 need to be arranged to move up and down synchronously. In fact, there are two layers in the coil 100, the inner layer is wound first and then the outer layer is wound. After winding of one coil 100 is completed, the clamp 301 is moved to clamp the copper wire between the coil 100 and the bobbin 304 and cut the copper wire at the same time.

[0078] A second top block 3068 is arranged on the fourth mounting frame 3063 and corresponds to the position of each second top rod 3067, the second top block 3068 is movable up and down, the upper end of the second top rod 3067 is arranged to abut against the second top block 3068, and the second top block 3068 can drive the second top rod 3067 to move up and down. Preferably, a bearing can be arranged at the upper end of the second top rod 3067, and the bearing is fixed on the second top block 3068 to reduce friction between the second top rod 3067 and the second top block 3068. The second top rod 3067 is driven by a pneumatic cylinder.

[0079] Further, a blowing pipe 3064 is arranged on the fourth mounting frame 3063 and corresponds to the position of each second rotating assembly, which blows air towards the position of winding and the air has a certain temperature, so as to melt the surface plastic of the copper wire of the wound coil to a certain extent, so that the copper wire has a certain viscosity, thereby enabling the mutually contacted copper wires to stick together, avoiding the coil from being scattered, and the coil and the second top rod 3067 located in the coil also have a certain viscosity. It should be noted that the melting is only to a certain extent, not complete melting, and the mutually contacted copper wires are still insulated.

[0080] The third mounting frame 3062 can move back and forth along the direction parallel to the first symmetry line, thereby moving the second rotating assembly to the position directly above the first rotating assembly and the placing block 203.

[0081] Two clamping plates 205 are arranged on the fixed disc 202 and correspond to the position of each winding station, and the clamping plates 205 correspond to the placing blocks 203 one by one and are located directly above the placing blocks 203. The clamping plates 205 can move back and forth along the corresponding first symmetry line, and a clamping groove 206 is arranged at the position of the clamping plate 205 for placing the coil 100, which is directly above the placing block 203. The diameter of the clamping groove 206 is equal to or slightly larger than the outer diameter of the coil 100. When the coil 100 is placed in position, the clamping plate 205 can move towards the coil 100 to clamp the coil 100. The clamping plate 205 is driven by a pneumatic cylinder.

[0082] When the winding is completed and the clamp 301 cuts off the copper wire, the fourth mounting frame 3063 moves upward by a distance. The third mounting frame 3062 drives the second rotating assembly to move to the position directly above the placing block 203 for placing the coil. The fourth mounting frame 3063 descends by a certain height, so that the coil 100 contacts the placing block 203, the clamping plate 205 moves towards the coil 100 to clamp the coil 100. Then, the second top rod 3067 moves upward, and the second sleeve 3065 is stationary, so that the coil is separated from the second top rod 3067. Finally, the fourth mounting frame 3063 moves upward, and the coil 100 is completely separated from the second rotating assembly and placed on the placing block 203. The clamping plate 205 is retracted.

[0083] Specifically, during the downward movement of the second top rod 3067 to the position directly above the placing block 203, the second top rod 3067 first contacts the upper end of the first guide rod 208 and moves downward by pressing the first guide rod 208. When the second top rod 3067 moves upward, the first guide rod 208 moves upward, that is, when the second top rod 3067 is pulled out of the coil, the first guide rod 208 enters the coil 100. The first guide rod 208 can position the coil, avoiding the coil 100 from moving on the placing block 203 in subsequent operations.

[0084] The integrated machine further comprises a laser module 4 arranged at the peeling station on the rack 1, which is used to irradiate laser from above or below the wire head of the coil to completely melt the surface plastic on a part of the wire head, and the wire head with the melted surface plastic is used for wiring.

The first laser module further comprises a first pressing assembly arranged on the fixed disc 202, which is used to prevent the coil 100 from shaking during laser peeling. The first pressing assembly comprises two pressing rods 404 and two positioning blocks 403, the two pressing rods 404 correspond to two coils 100 at the first peeling station respectively, and the pressing rod 404 is used to press the wire head of the coil 100. The two positioning blocks 403 correspond to two coils 100 at the first peeling station respectively, and the positioning block 403 is used to press the main part of the coil 100. When viewed from above, the pressing rod 404 and the corresponding positioning block 403 have a gap in the direction parallel to the corresponding first symmetry line, and the light of the laser passes through the gap to peel the specified position on the wire head. The two pressing rods 404 and the two positioning blocks 403 can move up and down synchronously, when the coil 100 moves to the first peeling station, the two pressing rods 404 and the two positioning blocks 403 move downward to press the coil 100, and when the peeling above is completed, the two pressing rods 404 and the two positioning blocks 403 move upward to release the coil 100, and the coil 100 is moved to the second peeling station under the drive of the turntable 201.
