Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of double-fed generators, in particular to a double-fed generator stator coil gluing device and method. BACKGROUND

[0002] Double-fed generators have been widely used in megawatt wind turbine generators due to their excellent grid-connection performance, wide speed regulation range and high efficiency power factor regulation capability. The inter-turn gluing process of the stator coil, as a core component, plays an irreplaceable key role in the manufacturing process. Inter-turn gluing is a process of thermosetting adhesion of multiple layers of mica tape wrapped flat copper wire by precise temperature control and application of specific pressure, forming a composite structure with excellent mechanical strength and electrical insulation performance.

[0003] Under the dual action of alternating electromagnetic force and mechanical vibration of the unit, long-term stress accumulation will cause the residual gap in the inter-turn insulation layer of the stator coil to continuously expand, resulting in a significant decrease in inter-turn dielectric strength, thereby causing partial discharge and eventually leading to insulation failure. Therefore, the quality of the inter-turn gluing process directly affects the risk of inter-turn breakdown of the double-fed generator stator coil.

[0004] Considering that manual inter-turn gluing will inevitably leave some residual gaps in a small number of inter-turn insulation layers, existing stator coils are often glued by a cold press. However, due to the limitations of existing technology, special molds need to be prepared for different specifications of stator coils, which cannot be flexibly adjusted in size as the motor capacity increases, and the special molds need to be frequently installed and removed, resulting in high labor intensity and low production efficiency. SUMMARY

As a preferred embodiment, profiling device 2 is shaped into shuttle structure by extruding the two ends of stator coil 1, such as the drawings Figure 1 And 3 As shown. The shuttle structure here is alternately connected by two circular arc segments and two straight line segments 101.

The first sliding rod 202 and the second sliding rod 203 are respectively slidably arranged in the support frame 201 along a first direction, i.e. both the first sliding rod 202 and the second sliding rod 203 move linearly relative to the support frame 201 along the first direction. The first sliding seat 204 and the second sliding seat 205 are respectively correspondingly arranged on the first sliding rod 202 and the second sliding rod 203 along a second direction, i.e. the first sliding seat 204 is slidably arranged on the first sliding rod 202 along the second direction, and the second sliding seat 205 is slidably arranged on the second sliding rod 203 along the second direction. The first pressing block 206 and the second pressing block 207 are respectively correspondingly arranged on the first sliding seat 204 and the second sliding seat 205, i.e. the first pressing block 206 is arranged on the first sliding seat 204 and slides synchronously with the first sliding seat 204, and the second pressing block 207 is arranged on the second sliding seat 205 and slides synchronously with the second sliding seat 205.

[0070] As shown in the accompanying drawings, the first direction and the second direction are perpendicular to each other. For example, in the accompanying drawings, the X axis represents the first direction, and the first direction is specifically the width direction of the stator coil 1; and the Y axis represents the second direction, and the second direction is specifically the length direction of the stator coil 1. Figure 1 Figure 1 For example, in the accompanying drawings, the X axis represents the first direction, and the first direction is specifically the width direction of the stator coil 1; and the Y axis represents the second direction, and the second direction is specifically the length direction of the stator coil 1.

[0071] The first pressing block 206 and the second pressing block 207 are both of a splicing structure, i.e. the lengths of the first pressing block 206 and the second pressing block 207 can be adjusted at will.

[0072] ​When the stator coil 1 is pressed, the first pressing block 206 and the second pressing block 207 are assembled first until the lengths of the first pressing block 206 and the second pressing block 207 are consistent with the length E of the straight line segment 101 on both sides of the stator coil 1; then the first sliding seat 204 and the second sliding seat 205 are adjusted in the second direction respectively, the first pressing block 206 slides synchronously with the first sliding seat 204 along the first sliding rod 202, and the second pressing block 207 slides synchronously with the second sliding seat 205 along the second sliding rod 203, so that the positions of the first pressing block 206 and the second pressing block 207 are adjusted in the second direction respectively, the first pressing block 206 and the second pressing block 207 are aligned with the straight line segment 101 on both sides of the stator coil 1 respectively, and the first pressing block 206 and the second pressing block 207 are prepared to press the straight line segment 101 of the stator coil 1; finally, the first sliding rod 202 and the second sliding rod 203 are adjusted in the first direction respectively, the first sliding rod 202 drives the first sliding seat 204 and the first pressing block 206 to slide synchronously in the first direction, and the second sliding rod 203 drives the second sliding seat 205 and the second pressing block 207 to slide synchronously in the second direction, so that the positions of the first pressing block 206 and the second pressing block 207 are adjusted in the first direction respectively by means of the first sliding seat 204 and the second sliding seat 205, and the first pressing block 206 and the second pressing block 207 are kept at a set distance. The set distance in the text refers to the width of the core structure.

[0073] In summary, by optimizing the structure of the pressing device 2, the length of the first pressing block 206 and the second pressing block 207 can be adjusted randomly according to the length of the straight line segment 101 of the stator coil 1, and the positions of the first pressing block 206 and the second pressing block 207 are adjusted in the first direction and the second direction respectively, so that the stator coil 1 with different lengths and widths is pressed, the size of the pressing device 2 can change with the size of the stator coil 1, and the pressing device 2 does not need to be replaced frequently due to the change of the size of the stator coil 1, which saves time and effort and effectively improves the production efficiency.

[0074] As a preferred embodiment, the profiling device 2 further comprises a first pressing plate 208, a second pressing plate 209, a first pressing cylinder and a second pressing cylinder, wherein the first pressing plate 208 is slidably arranged in the first sliding base 204 along the first direction, the first pressing block 206 is arranged on the first pressing plate 208, the first pressing plate 208 is used for supporting the first pressing plate 208, the first pressing cylinder is fixedly arranged on the first sliding base 204 and is fixedly connected with the first pressing plate 208, and is used for driving the first pressing plate 208 to move the first pressing block 206 along the first direction, so as to ensure that the first pressing cylinder provides sufficient profiling pressure to extrude the stator coil 1. Similarly, the second pressing plate 209 is slidably arranged in the second sliding base 205 along the first direction, the second pressing block 207 is arranged on the second pressing plate 209, the second pressing plate 209 is used for supporting the second pressing plate 209, the second pressing cylinder is fixedly arranged on the second sliding base 205 and is fixedly connected with the second pressing plate 209, and is used for driving the second pressing plate 209 to move the second pressing block 207 along the first direction, so as to ensure that the second pressing cylinder provides sufficient profiling pressure to extrude the stator coil 1. The first pressing cylinder and the second pressing cylinder can be air cylinders, and the pressing forces of the first pressing cylinder and the second pressing cylinder can be adjusted according to the actual width C and the actual height D of the single coil of the stator coil 1.

[0075] The profiling device 2 further comprises a control device connected with the first pressing cylinder and the second pressing cylinder.

[0076] When the control device obtains the actual width C and the actual height D of the single coil of the stator coil 1, the control device automatically adjusts the current pressing forces of the first pressing cylinder and the second pressing cylinder through processing and operation until the current pressing forces correspond to the actual width C and the actual height D of the single coil of the stator coil 1, respectively. That is, the pressing forces of the first pressing cylinder and the second pressing cylinder in the present application can automatically change with the actual width C and the actual height D of the single coil of the stator coil 1, so that the first pressing cylinder and the second pressing cylinder can adapt to stator coils 1 of different specifications, and the profiling device 2 does not need to be frequently replaced due to the too thick or too thin single coil of the stator coil 1, which saves time and effort and is beneficial to improve production efficiency.

[0077] It should be noted that after obtaining the actual width C and the actual height D of the single coil of the stator coil 1, the processing and operation process of the control device includes judging whether the current pressing forces of the first pressing cylinder and the second pressing cylinder match the actual width C and the actual height D of the single coil of the stator coil 1, if yes, maintaining the current pressing forces, and if no, calling the set pressing forces matched with the actual width C and the actual height D of the single coil, and adjusting the current pressing forces of the first pressing cylinder and the second pressing cylinder to the set pressing forces.

[0078] As a preferred embodiment, the first pressing block 206 comprises a plurality of first assembling blocks 2061 stacked along the second direction, and a first clamping plate is fixedly arranged on one side of the first pressing plate 208, one side of each first assembling block 2061 is formed with a first clamping protrusion, and the first clamping protrusion is clamped and matched with a first clamping groove arranged on the first clamping plate, so as to facilitate disassembly and assembly of the first assembling block 2061, and the operation is more time-saving and labor-saving, and the efficiency is higher. Similarly, the second pressing block 207 comprises a plurality of second assembling blocks 2071 stacked along the second direction, and a second clamping plate is fixedly arranged on one side of the second pressing plate 209, one side of each second assembling block 2071 is formed with a second clamping protrusion, and the second clamping protrusion is clamped and matched with a second clamping groove arranged on the second clamping plate, so as to also improve the efficiency. Of course, the structures of the first pressing block 206 and the second pressing block 207 are not limited to this. In order to improve the reliability, stop clamping plates can be additionally arranged at both ends of the first pressing block 206 and the second pressing block 207, so as to limit the positions of the first pressing block 206 and the second pressing block 207 in the second direction, and clamp the first pressing block 206 and the second pressing block 207, thereby preventing the first pressing block 206 and the second pressing block 207 from loosening.

[0079] As a preferred embodiment, the profiling device 2 further comprises a first transmission assembly, a first driving motor 210, a second transmission assembly and a second driving motor 211. One end of the first transmission assembly is connected with the first sliding seat 204, and the other end thereof is connected with the first driving motor 210, so that the first driving motor 210 drives the first sliding seat 204 to slide along the first sliding rod 202 through the first transmission assembly, and adjusts the position of the first pressing block 206 in the second direction. One end of the second transmission assembly is connected with the second sliding seat 205, and the other end thereof is connected with the second driving motor 211, so that the second driving motor 211 drives the second sliding seat 205 to slide along the second sliding rod 203 through the second transmission assembly, and adjusts the position of the second pressing block 207 in the second direction. Preferably, the first pressing block 206 and the second pressing block 207 are symmetrically arranged.

[0080] The first transmission assembly and the second transmission assembly in the embodiment are preferably screw-nut pairs, have high transmission accuracy, ensure the moving positions of the first pressing block 206 and the second pressing block 207 to be accurate, can accurately align the straight sections 101 on both sides of the stator coil 1, and are beneficial to providing production quality. Of course, the types of the first transmission assembly and the second transmission assembly are not limited to this.

[0081] The first drive motor 210 and the second drive motor 211 are respectively connected to the control device. When the control device obtains the actual outer coil length A (i.e., the shuttle length of the shuttle structure), the actual inner coil width B (i.e., the diameter of the pull shaft of the shuttle structure), and the actual width C of a single coil of the stator coil 1, the control device starts the first drive motor 210 and the second drive motor 211 to automatically adjust the positions of the first slide 204 and the second slide 205 in the second direction. The first pressure block 206 moves automatically with the first slide 204 in the second direction, and the second pressure block 207 moves automatically with the second slide 205 in the second direction until the first pressure block 206 and the second pressure block 207 are respectively aligned with the straight segments 101 on both sides of the stator coil 1. In this way, the positions of the first pressure block 206 and the second pressure block 207 are automatically adjusted in the second direction, ensuring that the positions of the first pressure block 206 and the second pressure block 207 can automatically change with the change of the size of the stator coil 1, resulting in a high degree of automation and higher production efficiency.

[0082] The pressing device 2 also includes a third transmission assembly and a third drive motor 212. One end of the third transmission assembly is connected to the first slide rod 202 and the second slide rod 203 respectively, and the other end is connected to the third transmission assembly. The third drive motor 212 is used to drive the first slide rod 202 and the second slide rod 203 to slide relative to each other through the third transmission assembly, so that the first slide rod 202 and the second slide rod 203 move closer to each other or separate from each other along a first direction. The third transmission assembly is preferably a lead screw and nut pair, which improves the displacement accuracy of the first slide rod 202 and the second slide rod 203, ensures the accurate distance between the first pressing block 206 and the second pressing block 207, and results in small dimensional errors in the pressed stator coil 1, which is beneficial to improving production quality.

[0083] The third drive motor 212 is connected to the control device. When the control device obtains the actual inner coil width B and the actual width C of a single coil of the stator coil 1, the control device starts the third drive motor 212 to adjust the positions of the first slide bar 202 and the second slide bar 203 in the first direction until the first pressure block 206 and the second pressure block 207 reach the set distance. In this way, the positions of the first pressure block 206 and the second pressure block 207 are automatically adjusted in the first direction, ensuring that the positions of the first pressure block 206 and the second pressure block 207 can change with the change of the width of the stator coil 1. This results in a high degree of automation and higher production efficiency.

[0084] The profiling device 2 further comprises a first guide rod 213 and a second guide rod fixed to the support frame 201 respectively, the first guide rod 213 is below the second guide rod, and the first guide rod 213 and the second guide rod are parallel to each other. The two ends of the first slide rod 202 are slidably connected with the first guide rod 213 and the second guide rod respectively, and the two ends of the second slide rod 203 are slidably connected with the first guide rod 213 and the second guide rod respectively, so that the first guide rod 213 and the second guide rod can not only provide support for the first slide rod 202 and the second slide rod 203, but also guide the first slide rod 202 and the second slide rod 203 to move linearly in the first direction. Specifically, the two ends of the first slide rod 202 and the second slide rod 203 are integrally formed with T-shaped protrusions respectively, and the first guide rod 213 and the second guide rod are respectively provided with T-shaped sliding grooves, and the T-shaped protrusions are slidably connected with the T-shaped sliding grooves. In addition, it should be noted that the two ends of the first guide rod 213 and the second guide rod are respectively fixed with stop blocks, and the stop blocks can be elastic blocks, such as rubber blocks, which can be used to limit the limit position of the first slide rod 202 and the second slide rod 203, prevent the first slide rod 202 and the second slide rod 203 from being separated, and provide damping and buffering for the first slide rod 202 and the second slide rod 203, thereby prolonging the service life of the first slide rod 202 and the second slide rod 203.

[0085] As a preferred embodiment, the gluing device of the stator coil of the doubly-fed generator further comprises a scanning device for scanning the stator coil 1 to obtain image information of the stator coil 1, and the scanning device can be a camera or the like. The scanning device is connected with the control device. When the scanning device obtains the image information of the stator coil 1, the scanning device sends the image information to the control device, and the control device obtains the actual width C of the single coil, the actual height D of the single coil, the actual outer ring length A, the actual inner ring width B and the length E of the straight line segment 101 of the stator coil 1 by processing the image information, as shown in the accompanying drawings, so as to automatically adjust the pressing force and the positions of the first pressing block 206 and the second pressing block 207. Of course, the acquisition method of each parameter of the stator coil 1 is not limited to scanning, for example, the parameters can also be pre-input to the control device through the operation panel, or detected and obtained by using a sensor. Figure 3

[0086] As shown in the accompanying drawings, Figure 2 ​As shown, the vulcanization device of the doubly-fed generator stator coil further comprises a drying device 4, a suspension track 6 and a suspension frame 7. The drying device 4 is arranged between the feeding area 3 and the profiling device 2, and is used for drying the inter-turn adhesive of the stator coil 1. The drying device 4 forms a drying tunnel, which is in a U-shaped structure. Thus, the whole vulcanization device forms a U-shaped production line, so that the whole vulcanization device occupies less space, is more smooth to operate, reduces the carrying distance and time, and has higher production efficiency. The suspension track 6 sequentially passes through the feeding area 3, the drying device 4, the profiling device 2 and the discharging area 5. The suspension frame 7 is slidably arranged on the suspension track 6, and is used for suspending the stator coil 1, so that the stator coil 1 is sequentially conveyed to the feeding area 3, the drying device 4, the profiling device 2 and the discharging area 5 by the suspension frame 7. This provides conditions for full automation of the whole vulcanization device, reduces the degree of manual participation, and is beneficial to improve the production efficiency. As a preferred embodiment, the suspension track 6 forms a U-shaped sliding groove, and the suspension frame 7 is hinged with a supporting roller, so that the supporting roller rolls along the U-shaped sliding groove, reduces the friction between the suspension frame 7 and the suspension track 6, and is beneficial to prolong the service life of the suspension track 6 and the suspension frame 7. The suspension frame 7 forms a hook, which is used for hanging the stator coil 1.

[0087] As a preferred embodiment, the vulcanization device of the doubly-fed generator stator coil further comprises a speed detection device and a suspension driving motor, which are connected with the control device. The speed detection device is used for detecting the current moving speed of the suspension frame 7, and can be a speed sensor.

[0088] When the control device obtains the set drying time of the stator coil 1 in the drying device 4, the control device adjusts the power of the suspension driving motor, changes the rotating speed of the supporting roller, adjusts the current moving speed of the suspension frame 7, until the current moving speed reaches the set moving speed, which matches the set drying time. In this way, the drying time of the stator coil 1 in the drying device 4 can be changed by changing the moving speed of the suspension frame 7, the drying time of the stator coil 1 can be accurately controlled, the automation degree is higher, and the production quality is effectively improved. It should be noted that the set drying time in the text can be changed according to the size change of the stator coil 1, and the set drying time can be pre-input into the control device or obtained by a sensor detecting the drying state of the stator coil 1, which is not limited here.

[0089] The embodiment of the present application further discloses a vulcanization method of a doubly-fed generator stator coil, which is applied to the above-mentioned vulcanization device of the doubly-fed generator stator coil, and the steps include:

[0090] S1, the positions of the first and second pressing blocks 206 and 207 of the profiling device 2 are adjusted according to the size of the stator coil 1 in advance, so that the first and second pressing blocks 206 and 207 are respectively aligned with the straight line segments 101 on both sides of the stator coil 1 and are kept at a set distance apart;

[0091] S2, when the hanger 7 moves along the suspension rail 6 to the feeding area 3, the stator coil 1 is loaded on the hanger 7;

[0092] S3, when the stator coil 1 moves with the hanger 7 from the feeding area 3 to the drying device 4, the stator coil 1 stays in the drying device 4 for a set drying time;

[0093] S4, when the stator coil 1 moves with the hanger 7 from the drying device 4 to the profiling device 2, the first and second pressing blocks 206 and 207 jointly extrude the stator coil 1 into a shuttle-shaped structure;

[0094] S5, the stator coil 1 moves with the hanger 7 from the profiling device 2 to the discharging area 5, thus completing the inter-turn gluing of the stator coil 1.

[0095] Therefore, during the gluing process of the stator coil 1, the positions of the first and second pressing blocks 206 and 207 of the profiling device 2 can be changed, so that the size of the profiling device 2 changes with the size of the stator coil 1. The profiling device 2 can be adapted to stator coils 1 of different sizes, without the need to frequently replace the profiling device 2, thus effectively improving the production efficiency.

[0096] It should be noted that in the present specification, the relationship terms such as first and second are only used to distinguish one entity from another, and do not necessarily require or imply any such actual relationship or order between the entities.

It should be noted that, for those skilled in the art, without departing from the principles of the present application, some improvements and modifications can be made to the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
