[0032] The following further details the specific embodiments of the present utility model with reference to the accompanying drawings.

[0033] As Figure 1 shown, the wire pay-off device for automatic winding of the stator coil of the present utility model includes a wire pay-off cover 1, a frame 2, a tensioner 3, and a copper wire transmission control mechanism 4;

[0034] The wire pay-off cover 1 is located on the feeding side of the frame 2, and the tensioner 3 is fixed above the copper wire transmission control mechanism 4 through the frame 2;

[0035] As Figure 3 shown, the copper wire transmission control mechanism 4 is located on the cross beam 21 of the frame 2. A connection groove 221 is vertically provided on the connecting arm 22 of the frame 2, and the cross beam 21 is detachably fixed to the connecting arm 22 through the connection groove 221 by a fourth fastener 222. The height of the copper wire transmission control mechanism 4 can be adjusted by the fourth fastener 222 along the connection groove 221, and the relative distance between the copper wire transmission control mechanism 4 and the tensioner 3 and the wire pay-off cover 1 can be adjusted according to the transmission requirements.

[0036] The bottom of the wire pay-off cover 1 is open. As Figure 2 shown, an outlet 11 is provided at the top of the wire pay-off cover 1. The copper wire coil is covered in the wire pay-off cover 1, and the copper wire is led out from the outlet 11. A ceramic ring 12 is provided at the outlet 11, and the ceramic ring 12 can reduce the wear of the outlet 11 on the copper wire. The wire pay-off cover 1 can play a role in positioning and dust prevention for the copper wire coil during unwinding, and prevent the copper wire coil from running off during unwinding.

[0037] The wire unwinding cover 1 is preferably a transparent cover body. The wire unwinding cover 1 made of transparent material can facilitate the operator to see through the cover body in time to control the unwinding situation of the copper wire coil in the cover body, which is convenient for dealing with abnormal conditions in time.

[0038] As Figure 4 shown, the tensioner 3 is provided with a flattening roller set 32 and a copper wire processing component 36. During the process of the unwound copper wire being transmitted through the flattening roller set 32, it is flattened by the flattening roller set 32, reducing the bending degree of the copper wire and avoiding affecting the transmission of the copper wire. The copper wire processing component 36 includes a transmission roller 361, a waxing sheet 362, and an elastic connecting piece 362. The transmission roller 361 is connected to one end of the elastic connecting piece 362, and the waxing sheet 362 is clamped at the other end of the elastic connecting piece 362. The copper wire is transmitted between the transmission roller 361 and the waxing sheet 362. The transmission roller 361 plays a guiding role for the copper wire, and the waxing sheet 362 performs waxing treatment on the surface of the copper wire, which plays a role in protecting the copper wire during the subsequent winding process.

[0039] The tensioner 3 is an existing magnetic tensioner. The change of the magnetic field conversion torque generates damping, thereby controlling the transmission tension of the copper wire. The copper wire is transmitted from the flattening roller set 32 of the tensioner 3 to the damping wheel 33 of the tensioner 3. A limiting rod 34 is provided on the circumference of the damping wheel 33. The limiting rod 34 plays a limiting role, so that the copper wire always transmits between the outer wall of the damping wheel 33 and the limiting rod 34. Subsequently, the copper wire is transmitted from the copper wire processing component 36 to the tension rod 35 of the tensioner 3.

[0040] As Figures 5-6 shown, the copper wire transmission control mechanism 4 includes an adjusting cylinder 41, a wire threading plate 42, a wire unwinding control cylinder 441, an upper plate 45, a lower plate 44, two limiting plates 46, and a guide rod 48. The piston rod of the adjusting cylinder 41 is connected to the wire threading plate 42. The wire threading plate 42 is provided with a wire threading opening 421. A guiding member 43 is provided on one side of the wire threading plate 42, and the guiding member 43 is provided with a guiding roller 431.

[0041] The upper plate 45 is fixed on the other side of the wire threading plate 42. The lower plate 44 is located below the upper plate 45, and the lower plate 44 is connected to the piston rod of the wire unwinding control cylinder 441. One ends of the two limiting plates 46 are hinged to the upper plate 45, and the other ends of the two limiting plates 46 are both connected to the lower plate 44.

[0042] The guide rod 48 is fixed on the housing of the adjusting cylinder 41, and a guide ring 481 is provided at the end of the guide rod 48.

[0043] The copper wire unrolled in the wire pay-off cover 1 passes through the guiding ring 481 from below, and is guided by the guiding ring 481 to be transmitted to the tensioner 3. The copper wire with adjusted tension passes through the threading port 421 via the guiding roller 431, and is transmitted from the upper plate 45 and the lower plate 44 to the winding equipment. When the winding equipment needs to stop wire pay-off, the piston rod of the wire pay-off control cylinder 441 controls the lifting of the upper plate 45, thereby driving the two hinged limiting plates 46 to close, and then clamping the copper wire, playing a role in immediately stopping the wire unrolling, avoiding the phenomenon of wire flying due to the transmission tension of the copper wire, resulting in repeated threading after the winding of a single stator coil is completed, and affecting the production line efficiency. When it is necessary to continue wire unrolling, the piston rod of the control cylinder 43 is reset, the two hinged limiting plates 46 open, releasing the clamping of the copper wire, and continuing the transmission of the copper wire and the winding of the coil.

[0044] The distance between the tensioner 3 and the threading port 421 can be adjusted by the telescopic movement of the piston rod of the position-adjusting cylinder 41. The housing of the position-adjusting cylinder 41 is provided with an installation groove 411 and a buckle 49. The guiding rod 48 is fixed in the installation groove 411 through the buckle 49, reducing the dislocation generated when the guiding rod 48 is pulled by the copper wire during the transmission of the copper wire. The buckle 49 is provided with a first fastener 491, and the buckle 49 is detachably fixed on the housing of the position-adjusting cylinder 41 through the first fastener 491, facilitating the adjustment of the positions of the guiding rod 48, the copper wire coil and the tensioner 3 along the installation groove 411.

[0045] The threading plate 42 is provided with an adjustment groove 422, and the guiding member 43 is detachably connected to the adjustment groove 422 through a second fastener 432, facilitating the adjustment of the height of the guiding roller 431 during equipment debugging to adapt to the wire transmission requirements of the coil winding equipment.

[0046] Rubber strips 47 are provided at the bottom of the upper plate 45 and the top of the lower plate 44. When the copper wire transmitted from the threading port 421 is transmitted between the upper plate 45 and the lower plate 44, the rubber strips 47 can protect the surface of the copper wire, avoiding the surface of the copper wire being scratched by the surfaces of the upper plate 45 and the lower plate 44 due to the up-and-down undulation during transmission.

[0047] The rubber strips 47 are fixed on the upper plate 45 and the lower plate 44 through third fasteners 471, and the third fasteners 471 are countersunk screws. The rubber strips 47 can be replaced through the third fasteners 471, and the countersunk screws can effectively avoid scraping the copper wire during transmission and avoid causing transmission accidents.

[0048] A protective strip 461 is provided on the side of the limiting plate 46. When the two limiting plates 46 clamp the copper wire, the protective strip 461 can play a protective role to avoid the surface wear of the copper wire.

[0049] The wire pay-off device for automatically winding the stator coil of the present utility model places the copper wire coil in the wire pay-off cover 1. The copper wire passes through the wire outlet 11 and enters the tensioner 3 for tension adjustment under the guiding action of the guiding ring 481. The freshly unreeled copper wire is too bent, and the guiding ring 481 can limit the transmission direction of the copper wire to avoid the phenomenon of flying wires. Subsequently, the copper wire enters the copper wire transmission control mechanism 4 from the wire threading port 421. The copper wire transmission control mechanism 4 can stop the copper wire when necessary. Finally, the copper wire is transmitted to the coil winding equipment.

[0050] The preferred embodiments of the present utility model have been specifically described above, but the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent variations or substitutions without departing from the spirit of the present utility model, and these equivalent variations or substitutions are all included within the scope defined by the claims of this application.
