Description

Technical Field

[0001] The present invention relates to the technical field of motor stators, and in particular to a straight-chain stator plastic-coated structure and a use method thereof. Background Art

[0002] The motor stator is an important component of the motor, usually composed of an iron core and a winding. The iron core is made of stacked silicon steel sheets and is used to concentrate and conduct the magnetic field. The winding is made of wound wires and is used to generate an electromagnetic field.

[0003] For example, in the publication number CN106130207A, “A stator core and a chain-type stator core sheet”, the chain-type stator core sheet is used for the stator core after being rounded, and comprises a plurality of tooth-shaped units connected in sequence, wherein two adjacent tooth-shaped units are connected via a connecting portion, a folding groove is provided on the inner side of the connecting portion, and an inwardly concave transition structure is provided on the outer side of the connecting portion, so that after the chain-type stator core sheet is rounded, the entire transition structure does not exceed the outer circle of the stator core after being rounded.

[0004] However, in the prior art, the traditional stator is composed of multiple layers of silicon steel sheets stacked together and then wound. During the production process, the wire needs to be wound on the teeth of the inner ring of the silicon steel sheet.

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Embodiment 1

[0039] Reference Figure 7 and Figure 8 As shown: a straight-chain stator plastic-coated structure includes a stator body 12, which is in the shape of an insert injection-molded strip. A tooth portion 11 is fixedly connected to one side of the stator body 12, a terminal 13 is fixedly installed on the top of the stator body 12, and a connector 10 is fixedly connected to one side of the stator body 12. Two adjacent stator bodies 12 are rotatably connected by the set connector 10, and multiple connectors 10 are connected in series end to end.

[0040] In this embodiment, the stator body 12 is processed into a strip shape by insert injection molding. Multiple stator bodies 12 are connected in series through side connectors 10 to form a straight chain structure. The tooth portion 11 arranged on the other side of the stator body 12 is used for winding. When winding, the stator body 12 is unfolded into an arc structure so that the tooth portion 11 protrudes alone. At this time, the difficulty of winding on the tooth portion 11 is greatly reduced. At the same time, an insulating layer is directly injection-molded on the tooth portion 11 to protect the tooth portion 11. The connection terminal 13 and other components are installed on the top of the stator body 12 to ensure that the stator body 12 can be used normally.

[0041] Embodiment 2

[0042] according to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a method for using a straight-chain stator plastic-coated structure uses a winding device, which includes a carrying platform 1, a vertical plate 2 and a winding assembly 3. A battery module 4 is fixedly installed on the top of the carrying platform 1, a wiring shell 9 is fixedly installed on the outer wall of the carrying platform 1, the vertical plate 2 is fixedly installed on the upper surface of the carrying platform 1, and a first reduction motor 7 is fixedly installed on one side of the vertical plate 2. The winding assembly 3 includes a connecting gear 31, a first gear 32, a second gear 33, a bending rod 35 and a cross bar 36. The output end of the first reduction motor 7 is fixedly connected to the gear shaft of the connecting gear 31, and the first gear 32 and the second gear 33 are both rotated and arranged. Installed on one side of the vertical plate 2, the connecting gear 31 is meshed with the first gear 32 and the second gear 33. The connecting gear 31, the first gear 32 and the second gear 33 are located on the same vertical plane. The first gear 32 and the second gear 33 are symmetrically distributed along the center line of the connecting gear 31. An extension support rod 34 is fixedly installed on one side of the first gear 32 and one side of the second gear 33. One end of the bending rod 35 is fixedly connected to one end of the cross bar 36. The bending rod 35 is rotatably connected to the extension support rod 34. The other end of the cross bar 36 is rotatably connected to a winding rod 311, and the winding rod 311 is used to wind the wire onto the surface of the stator body 12.

[0043] In this embodiment, the vertical plate 2 and the carrying platform 1 form a T-shaped structure. The winding device is used to perform winding processing on the stator body 12. When in use, the material required for coating is wound on the winding rod 311, and then the first reduction motor 7 is started to drive the connecting gear 31 to rotate. The first reduction motor 7 is powered by the battery module 4, and the lines are built into the wiring shell 9;

[0044] When the connecting gear 31 rotates, it will drive the first gear 32 and the second gear 33 to rotate at the same time. Since the first gear 32 and the second gear 33 are symmetrically distributed along the center line of the connecting gear 31, when driven by the connecting gear 31, the first gear 32 and the second gear 33 rotate in the same direction. Figure 2 For example, when the connecting gear 31 rotates clockwise, the first gear 32 and the second gear 33 both rotate counterclockwise;

[0045] During the rotation of the first gear 32 and the second gear 33, the extended support rod 34 located on the side will drive the bending rod 35 to move the cross bar 36 in a counterclockwise circular route, and the winding rod 311 is installed on the cross bar 36. The circularly moving winding rod 311 can complete the winding process of the stator body 12, and because the first gear 32 and the second gear 33 are in an unchanging vertical plane, the problem of misalignment can also be avoided.

[0046] Embodiment 3

[0047] according to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a direction adjustment component 5 is rotatably installed at one end of the vertical plate 2, and the direction adjustment component 5 includes a driven gear 51, a turntable 52 and a bearing rod 53. The bearing rod 53 is fixedly installed at the edge of the turntable 52, and the turntable 52 is fixedly installed on the top of the driven gear 51. A second reduction motor 8 is fixedly installed on one side of the vertical plate 2, and a fan gear 54 is fixedly connected to the output end of the second reduction motor 8. The fan gear 54 is meshingly connected with the driven gear 51, and a notch 6 is opened at the bottom of the vertical plate 2 to accommodate the fan gear 54.

[0048] In this embodiment, the direction adjustment component 5 is mainly used to fix the stator body 12. The stator body 12 is placed on the bearing rod 53. The bearing rod 53 is provided with an opening matching the tooth portion 11 on the stator body 12. The stator body 12 is deployed in the bearing rod 53 in an expanded arc structure. At this time, the tooth portion 11 will be exposed from the opening. Since the whole is an expanded arc structure, only one tooth portion 11 on the stator body 12 is exposed at a time, which is convenient for winding processing. After the winding device completes a winding process, the first reduction motor 7 is stopped and the second reduction motor 8 is started. The second reduction motor 8 drives the driven gear 51 to rotate through the fan gear 54 to achieve the purpose of driving the turntable 52 to rotate. The rotation of the turntable 52 can rotate the other stator body 12 to the side of the winding rod 311. The notch 6 at the bottom of the vertical plate 2 can ensure that the fan gear 54 can rotate normally. The arc length of the fan gear 54 is one-fourth of the circumference of the driven gear 51.

[0049] Embodiment 4

[0050] according to Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, a first belt transmission assembly 37 is movably connected to the outer wall of the gear shaft of the connecting gear 31, one end of the first belt transmission assembly 37 is movably connected to a rotating rod 312, one end of the rotating rod 312 is rotatably connected to a connecting end 38, a second belt transmission assembly 39 is movably connected to the outer wall of the connecting end 38, the other end of the second belt transmission assembly 39 is movably connected to a pull-back rod 310, one end of the pull-back rod 310 is fixedly connected to a winding rod 311, the other end of the pull-back rod 310 is rotatably connected to a positioning block 313, and the positioning block 31 The rotating rod 312 is fixedly mounted on one side of the cross bar 36, one end of the rotating rod 312 is rotatably connected with the anti-drop plate 319, the rotating rod 312 is slidably connected to the inside of the vertical plate 2, a cavity 314 is provided inside the rotating rod 312, one end of the connecting end 38 is located inside the cavity 314, an inclined protrusion 318 is fixedly mounted on the inner wall of the rotating rod 312, an accommodating cylinder 315 is fixedly mounted on the outer wall of one end of the connecting end 38, a tension spring 317 is fixedly mounted on the inner wall of the accommodating cylinder 315, and one end of the tension spring 317 is fixedly connected to the contact rod 316.

[0051] In this embodiment, the connecting gear 31 also drives the rotating rod 312 through the first belt transmission assembly 37 while rotating, so as to Figure 2 , Figure 5 and Figure 6 For example, when the connecting gear 31 rotates clockwise, the rotating rod 312 will also rotate clockwise synchronously. During the rotation of the rotating rod 312, the inclined protrusion 318 located on the inner wall of the cavity 314 will push the contact rod 316, and the contact rod 316 is connected to the inside of the accommodating tube 315 through the tension spring 317. When the inclined protrusion 318 contacts the contact rod 316, the contact rod 316 will be pressed into the inside of the accommodating tube 315. In this process, the friction between the inclined protrusion 318 and the contact rod 316 can push the connecting end 38 to rotate.

[0052] When the contact rod 316 contacts the top of the arc of the inclined protrusion 318, the friction force reaches a peak value. Then, when the rotating rod 312 continues to rotate, the inclined protrusion 318 rotates away from the contact rod 316, and the friction force gradually decreases. During the whole process, the connecting end 38 drives the pull-back rod 310 to rotate clockwise through the second belt transmission assembly 39, but the cross bar 36 keeps rotating counterclockwise at this time. The opposite rotation direction causes the winding rod 311 to generate a certain pulling force on the wire, so as to cause the wire to completely adhere to the surface of the stator body 12.

[0053] When the inclined protrusion 318 is completely separated from the contact rod 316, the connecting end 38 which has lost the friction force will stop rotating, thereby achieving the purpose of the connecting end 38 rotating once while the rotating rod 312 rotates one circle. Intermittently pulling the pull-back rod 310 can avoid the problem of wire loosening during the winding process. The rotating rod 312 is slidably connected to the vertical plate 2 through the anti-slip plate 319, and a through hole is opened on the vertical plate 2 for the rotating rod 312 to move up and down, so that the overall structure can adapt to the movement of the cross bar 36.

[0056] 1) Deploy the stator: deploy the stator body 12 in an expanded arc structure onto the bearing rod 53 of the steering assembly 5, so that the teeth 11 are exposed at the opening;

[0057] 2) Arrange the materials required for winding: prepare the winding materials and wind them onto the outer wall of the winding rod 311;

[0058] 3) Start winding: Start the first reduction motor 7 to drive the connecting gear 31, the connecting gear 31 drives the first gear 32 and the second gear 33 to rotate, and the extension rod 34 on the side of the first gear 32 and the second gear 33 drives the bending rod 35 to move the cross bar 36 in a circular path. In this process, the winding rod 311 can wind the wire onto the surface of the stator body 12;

[0059] 31) Synchronous transmission: The connecting gear 31 synchronously drives the rotating rod 312 to rotate through the first belt transmission assembly 37;

[0060] 32) Power transmission: During the rotation of the rotating rod 312, the friction between the inclined protrusion 318 and the contact rod 316 is used to drive the connecting end 38 to rotate intermittently;

[0061] 33) Tightening the wire: The connecting end 38 drives the pull-back rod 310 through the second belt drive assembly 39, so that the winding rod 311 rotates during the winding operation to tighten the wire;

[0062] 4) Replace the new stator: start the second reduction motor 8, drive the driven gear 51 to rotate through the sector gear 54, complete the adjustment of the turntable 52, rotate the other stator body 12 to one side of the winding rod 311, and then repeat step 3).

The method for using the straight-chain stator plastic-coated structure according to claim 8, characterized in that: In step S3, the starting winding further includes the following steps: S31, synchronous transmission: the connecting gear (31) synchronously drives the rotating rod (312) to rotate through the first belt transmission assembly (37); S32, power transmission: during the rotation of the rotating rod (312), the friction between the inclined protrusion (318) and the contact rod (316) is used to drive the connecting end (38) to rotate intermittently; S33, tightening the wire: the connecting end (38) drives the pull-back rod (310) through the second belt drive assembly (39), so that the winding rod (311) rotates during the winding operation to tighten the wire.
