During the rotation and movement of the clamping disc 16, the attitude of the transition plate 41 does not change, which is convenient for the piston rod of the control cylinder 35 to extend and retract.

[0039] The working principle of the present utility model:

[0040] In the initial state, the stator coil 15 is placed on the placement plate 33, and the clamping disc 16 and the placement plate 33 clamp both ends of the stator coil 15; the sliding plate 13 is located at one end of the stator coil 15.

[0041] Fix the starting ends of the strips in the three mounting boxes 28 on the winding part to be wound on one side of the stator coil 15, start the alignment cylinder 20, and move the three mounting boxes 28 along the annular track; at the same time, start the driving motor, drive the lead screw 22 to rotate through the driving pulley 24, the synchronous belt 25 and the transmission pulley 26. Under the cooperation of the threaded block 43 and the lead screw 22, the sliding plate 13 moves together with the threaded block 43;

[0042] The three mounting boxes 28 rotate around the winding part to be wound of the stator coil 15 and move along the length direction of the stator coil 15 at the same time, ensuring lateral translation during the winding and bandaging process with a constant tension, realizing the winding and bandaging of the three tape heads, controlling the lateral translation speed, and making each layer of strip overlap by 1 / 2 and cover the winding part to be wound.

[0043] When the winding part on one side is wound, the moving motor 23 and the driving motor are both paused, and the strip is cut off from the mounting box 28;

[0044] The alignment cylinder 20 and the limit cylinder 21 are started respectively, so that the two sliding frames 29 slide to both sides, driving the alignment frame 14 and the limit frame 19 to separate;

[0045] The lifting cylinder 37 is started, and its piston rod is controlled to extend. The mounting frame 18 is lifted, and components such as the reversing motor 17 and the placement plate 33 are lifted together with the mounting frame 18, and the placement plate 33 and the backing plate 34 are separated; after reaching a certain height, the reversing motor 17 is started, and its output shaft is controlled to rotate 180°. The connecting plate 36, the placement plate 33, the limit block 32 and the clamping disc 16 rotate together with it; this is carried out at both ends of the machine table 11, the stator coil 15 is turned over. After the stator coil 15 is turned over, the lifting cylinder 37 controls its piston rod to reset, the stator coil 15 drops, and the clamping disc 16 contacts the placement plate 33; then the alignment cylinder 20 and the limit cylinder 21 are started, and the alignment frame 14 and the limit frame 19 are reconnected;

[0046] At this time, the starting ends of the strips in the three mounting boxes 28 are fixed again on the winding part to be wound on the unwound side of the stator coil 15. The moving motor 23 and the driving motor are started at the same time, the sliding plate 13 moves in the reverse direction, and at the same time the three sliding plates 13 rotate around the winding part to be wound of the stator coil 15. After the sliding plate 13 returns to the initial position, both sides of the stator coil 15 are wound, and the equipment stops running.

[0047] The alignment cylinder 20 and the limit cylinder 21 control the separation of the alignment frame 14 and the limit frame 19. The control cylinder 35 is activated, and its piston rod extends to push the transition plate 41, the threaded sleeve 39, and the clamping disc 16 away from the mounting plate 33. When the clamping disc 16 moves, under the action of the threaded rod 31 and the threaded sleeve 39, the clamping disc 16 rotates around the axis of the threaded rod 31, and the part of the clamping disc 16 located directly above the limit block 32 deflects to one side, so that the stator coil 15 can be smoothly taken out of the device. Then, the ends of the stator coil 15 are bandaged manually, and the bandage head is processed.

[0048] In addition, in another embodiment of the present invention, the shapes of the alignment frame 14 and the limit frame 19 in the bandaging mechanism are not limited to symmetry between the two. Refer to the attached Figure 7 and 8 . In the implementation manner of the attached Figure 7 , when the alignment frame 14 and the limit frame 19 are spliced and separated, they both need to slide. To meet the accuracy of bandaging, the moving motor 23 needs to have a stable working attitude. When the transmission gear 40 moves together with the limit frame 19, a tensioning structure is needed to keep the belt drive in tension; and the alignment frame 14 needs to move inside the stator coil 15, so the size of the alignment frame 14 must be smaller than the size of the hollow part of the stator coil 15;

[0049] In the implementation manner of the attached Figure 8 , the upper part of the alignment frame 14 is smooth, and the alignment frame 14 does not need to move. Only when the limit frame 19 moves away from the alignment frame 14 can the stator coil 15 be taken out from above. And the transmission gear 40 is arranged on one side of the alignment frame 14, and the relative positions of the transmission gear 40 and the moving motor 23 remain unchanged during operation, improving the working accuracy of the device; at the same time, since the alignment frame 14 does not need to move, the alignment frame 14 can be designed to have a size such that its two sides just contact the inner side wall of the stator coil 15, so as to be applicable to the bandaging work of smaller-sized stator coils 15 and improve the applicability of the device.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.
