[0020] like Figure 1 , 2 As shown, the belt 30 has a relaxed state and a tight state. When the belt 30 is in the relaxed state, the winding unit 20 drives the yarn to wind around itself, and the belt 30 is not in contact with the winding unit 20. When the belt is in the tight state, the belt 30 rubs against the yarn of the winding unit 20 itself, and the yarn is wound around the coil via the winding unit 20.

[0021] Through the arrangement of the cover 10, the winding unit 20, the belt 30 and the driving mechanism 40, the driving mechanism 40 includes a connecting portion 41, a driving portion 42 and an adjusting support portion 43. When the yarn tape on the winding unit 20 needs to be wrapped around the coil, the belt 30 needs to be abutted against the yarn tape on the winding unit 20. First, the adjusting support portion 43 is fixed to an external object so that the travel trajectory of the connecting portion 41 and the belt 30 is in a horizontal straight line state. The end of the belt 30 located outside the cover 10 is installed on the connecting portion 41. The driving portion 42 drives the connecting portion 41 to move in a straight line in the horizontal direction. The belt 30 moves in a straight line along with the movement of the connecting portion 41. The stator coil winding belt 20 is moved by the movement to tighten the loose belt 30, and the belt 30 is in contact with the yarn tape wound on the winding unit 20, so that the winding unit 20 can cover the coil with the yarn tape. The adjusting support part 43 can be adjusted in height according to the actual situation of the belt 30 on site to ensure that the belt 30 is in a horizontal and straight state during the movement. The belt tensioning mechanism of the stator coil winding yarn tape can adjust the position according to the travel trajectory of the belt 30 to make the belt 30 move horizontally and straightly, avoiding the belt 30 from twisting during the movement, so as to ensure the stability of the yarn tape, so that the winding unit 20 can wind the coil efficiently and with quality.

[0022] In this embodiment, the belt 30 is made of polyurethane material, which is resistant to moisture, acid, alkali, oil, and fatigue, and has a service life of 12 months.

The rotating part and one side of the winding part are both provided with a second opening for the coil to enter. When the coil enters the first opening and the second opening, the rotating part drives the winding part to rotate so as to wrap the yarn around the winding part.

[0024] The rotating part drives the winding part to rotate, and the yarn tape can be wound on the winding part, so that the yarn tape can be wrapped around the coil later.

[0025] like Figure 1 , 2 As shown, in the present embodiment, specifically, the adjustment support portion 43 includes a connecting piece 431, a bolt 432 and a support plate 433, the connecting piece 431 is provided with an annular locking groove, the bolt 432 is fixedly connected to an external object through the annular locking groove of the connecting piece 431, the support plate 433 is fixed to one side of the connecting piece 431, and the top of the support plate 433 is fixedly connected to the driving portion 42.

[0026] The bolt 432 can be adjusted in position on the annular locking groove of the connecting piece 431 to facilitate height adjustment of the connecting piece 431 , thereby facilitating height adjustment of the driving portion 42 and the connecting portion 41 to meet the horizontal straight travel trajectory of the belt 30 .

[0027] In this embodiment, specifically, the driving part 42 includes a bearing seat 421 and a cylinder 422 , the bearing seat 421 is fixedly connected to the support plate 433 , the cylinder 422 is installed on the bearing seat 421 , and the cylinder 422 is fixedly connected to the connecting part 41 .

[0028] In this embodiment, the supporting seat 421 is configured to be “L” shaped.

[0029] The cylinder 422 can drive the connecting portion 41 to move horizontally and linearly.

[0030] In this embodiment, specifically, the connecting part 41 includes a moving block 411 and a limiting slider 412, the moving block 411 slides on the supporting seat 421 along the horizontal direction, the limiting slider 412 is fixed to the moving block 411 and slides on the supporting seat 421, and one end of the belt 30 is detachably connected to one side of the moving block 411 to facilitate the replacement of the belt 30.

[0031] The setting of the moving block 411 makes it easier for the cylinder 422 to drive the belt 30 to move. The limiting slider 412 limits the moving block 411, so that the moving block 411 can only move horizontally and linearly on the bearing seat 421, ensuring the horizontal and linear movement trajectory of the belt 30.

[0032] In this embodiment, further, a sliding groove for the limiting slider 412 to move is provided on the bearing seat 421 along a horizontal straight line direction.

[0035] In this embodiment, further, the winding portion is a missing strap ring 23, the missing strap ring 23 is fixed to one side of the missing gear ring 21, and a strap area for the yarn to be wound is formed on the missing strap ring 23. Two small gears 22 are provided, and the two small gears 22 are respectively engaged with the notched gear ring 21.

[0036] The axes of the two small gears 22 are connected to the output shaft of the external motor. The rotation of the two small gears 22 drives the notched gear ring 21 to rotate, so that the notched band ring 23 can wrap the yarn, or the yarn wrapped on the notched band ring 23 can be covered on the coil surface.

[0037] The belt tensioning mechanism of the stator coil winding belt further includes a robot 50 , which is arranged on one side of the cover 10 to move the coil to the processing cavity of the cover 10 .

[0038] The setting of the robot 50 can move the coil to the processing chamber of the cover 10, so as to facilitate the winding unit 20 to wrap the coil with the yarn tape.

[0039] The configuration of the robot 50 is conventional technology in the art and is well known to those skilled in the art, so it will not be described in detail here.

[0040] The connecting piece 431 is fixed to the external object by bolts 432, the support plate 433 is fixed, and the bearing seat 421 is fixed, so that the moving block 411 is located in the horizontal straight track of the belt 30. If it is necessary to adjust the height of the moving block 411, it can be adjusted by bolts 432 and the connecting piece 431. The cylinder 422 drives the moving block 411 and the limiting slider 412 to move horizontally and linearly on the bearing seat 421. The moving block 411 drives the belt 30 to move linearly, so that the belt 30 is in contact with the tape on the missing strap ring 23, which facilitates the winding unit 20 to wrap the coil with tape.

[0041] The driving mechanism 40 can switch the belt 30 between a loose initial state and a tight state.

[0042] The specific implementation methods of the utility model described above do not constitute a limitation on the protection scope of the utility model.
