Abstract
Description
Technical Field
[0001] This invention relates to the field of stator coil production for large hydropower station motors, and in particular to a tape winding device for stator coil production lines. Background Technology
[0002] Driven by the energy structure transformation strategy, the installed capacity of hydropower stations continues to expand. For hydropower stations, the performance of the generator directly determines the power generation efficiency, stability, and service life of the unit. The stator coil, as the "heart" of the large generator, is a key factor affecting the overall quality of the generator. The production process of the stator coil for hydropower generators mainly includes material preparation, transposition braiding (braiding results in rectangular rods composed of two rows of flat copper sheets (i.e., electromagnetic wires)), insulation pad wrapping, straight-line curing, chamfering and removal of release tape, short-circuit testing, and end forming. Among these, insulation pad wrapping involves evenly winding release tape around the rod (with insulating pads on both narrow sides) to fix the insulation pads to the rod, ensuring subsequent straight-line curing. After wrapping, the two ends of the release tape need to be fixed to prevent it from loosening and affecting the curing quality of the rod. In existing stator coil production lines, the release tape at both ends of the rod is fixed manually, with manual wrapping of the tape, which is inefficient and makes it difficult to guarantee the wrapping strength. Summary of the Invention
[0003] In view of this, the present invention proposes a tape winding device for a stator coil production line.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: The tape winding device for a stator coil production line of the present invention includes an installation platform, a bar limiting mechanism, a tape winding mechanism, and a bar support mechanism arranged front and rear on the installation platform, and also includes a tape cutting mechanism arranged in the tape winding mechanism. The tape winding mechanism includes a stand, a belt drive mechanism with a reduction ratio, and a tape holder driven by the belt drive mechanism. The belt drive mechanism includes a winding motor mounted on the stand and a winding gear mounted in the middle of the stand. The drive gear on the winding motor is connected to the winding gear via a rack and pinion belt. The tape holder is fixed to the winding gear. The stand has a central hole, and the front side of the stand near the central hole has multiple evenly spaced support bearings. The winding gear has a ring structure, and its inner ring rolls with the support bearings.
[0005] The beneficial effects are: the tape winding mechanism of the present invention has a circular winding gear, which can drive the tape roll to rotate with it during its rotation. The tape on the tape roll is released from the force, and the bar can pass through the winding gear. During this process, the winding motor drives the winding gear to rotate, thereby realizing the tape wrapping at the end of the bar. It can also ensure the consistency of the winding force during the tape winding process and ensure the winding effect.
[0006] The present invention installs a bar limiting mechanism on the front side of the tape winding mechanism to prevent the bar from becoming skewed during the winding process and affecting the winding; and installs a bar support mechanism on the rear side of the tape winding mechanism to provide support for the bar and ensure continuous winding of the tape on the bar.
[0007] Preferably, the bar limiting mechanism includes a limiting power source, a pair of fixed seats disposed on the front side of the upright, a bidirectional lead screw rotatably disposed on the fixed seats, and a pair of limiting components disposed on the bidirectional lead screw. The limiting components include a nut seat screwed onto the bidirectional lead screw and a limiting roller vertically fixed to the nut seat. The two limiting rollers are spaced apart to limit the bar. The limiting power source is connected to the bidirectional lead screw and drives the two limiting rollers to open and close through the bidirectional lead screw.
[0008] This invention installs a wire bar limiting mechanism in front of the tape winding mechanism to limit the wire bar and prevent it from deviating during movement, which would affect the winding quality. In addition, the bidirectional lead screw can open and close the two limiting rollers when rotating. The distance between the two limiting rollers can be flexibly adjusted according to the width of the wire bar, thereby limiting wire bars of different widths and meeting the wrapping requirements of wire bars of different specifications.
[0009] More preferably, the limiting power source includes a limiting motor and a first synchronous belt drive pair connected to the limiting motor. The driven pulley of the first synchronous belt drive pair is installed at one end of the bidirectional lead screw. A first slide rail parallel to the bidirectional lead screw is provided below it, and the nut seat is slidably engaged with the first slide rail. The first synchronous belt drive pair and the bidirectional lead screw of the present invention are arranged at 90 degrees, resulting in a compact structure.
[0010] The tape cutting mechanism includes a mounting base horizontally fixed to the rear side of the stand, and a tape pressing structure and a tape cutting structure spaced apart on the left and right. A mounting shaft located in the central hole is mounted on the front side of the mounting base. The tape pressing structure includes a first cylinder, a horizontally arranged first rack, and a first gear rotatably arranged on the mounting shaft. The first gear is located above the first rack and meshes with the first rack. The first cylinder is connected to the first rack, and a first pressing plate is fixedly connected to the first gear. The first cylinder drives the first rack to move horizontally, causing the first rack to drive the first pressing plate to rotate. The tape cutting structure includes a second cylinder, a horizontally arranged second rack, and a second gear rotatably arranged on the mounting shaft. The second gear is located above the second rack and meshes with the second rack. The second cylinder is connected to the second rack, and a cutting plate with a cutter is fixedly connected to the second gear. The second cylinder drives the second rack to move horizontally, causing the rack to drive the cutting plate to rotate. The first cylinder and the second cylinder are installed at the bottom of the mounting base along the length of the rod, with the first cylinder located behind the first rack and the second cylinder located behind the second rack.
[0011] The beneficial effects are: both the first pressure plate and the cutting plate can rotate around the mounting shaft, allowing for flexible adjustment of the positions of the pressure plate and the first cutter. When the tape needs to be cut, the pressure cylinder first drives the pressure plate through the pressure rack and pressure gear, causing the pressure plate to press the tape above it upwards. The first cutting cylinder then lifts the cutting plate upwards through the cutting rack and cutting gear, thereby cutting the tape.
[0012] More preferably, the tape winding device for a stator coil production line according to the present invention further includes a tape auxiliary bonding structure disposed on the left side of the tape pressing structure. The tape auxiliary bonding structure includes a third gear disposed on the mounting shaft and a third rack located below and meshing with the third gear. It also includes a third cylinder horizontally disposed at the bottom of the mounting base, the third cylinder being drivenly connected to the third rack. A second pressing plate is fixedly connected to the third gear. In actual operation, the second pressing plate can be used to lift the tape upwards, causing it to adhere to the end of the coil bar, providing a foundation for tape winding.
[0013] Preferably, the free end of the second top pressure plate extends toward the free end of the first top pressure plate, and the free end of the cutting plate extends toward the free end of the first top pressure plate. The first top pressure plate has a T-shaped structure and is located above the cutting plate. A first sponge is provided at the free end of the second top pressure plate, and a second sponge is provided on the cutting plate corresponding to the first top pressure plate. The cutter is fixedly connected to the cutting plate near the second sponge. In this invention, the first sponge protects the tape and wire rod, reducing damage caused by hard contact; the second sponge prevents hard contact between the cutting plate and the first top pressure plate, reducing machine noise.
[0014] Preferably, three T-shaped supports are arranged side by side at the bottom of the central hole, with the first rack, second rack and third rack located on the horizontal support portion of their respective supports.
[0015] Preferably, the bar support mechanism includes a support unit, a power unit, and a lifting power mechanism that drives the power unit to move up and down on the mounting platform. The support unit includes a plurality of conveying rollers arranged in a row. The power unit includes a motor reducer and a second synchronous belt drive pair driven by the motor reducer. The second synchronous belt pair is located above the support unit and presses on the bar to make the bar move forward.
[0016] The beneficial effects are: the present invention uses a conveyor roller to provide rigid support for the bar and a power unit to provide forward power for the bar, thereby ensuring multiple turns of continuous winding of the tape at the end of the bar.
[0017] More preferably, the lifting power mechanism includes a portal frame mounted on the mounting platform, a lifting power source fixed to the portal frame, and a vertical base driven to lift by the lifting power source. The lifting power source includes a lifting cylinder vertically mounted on the crossbeam of the portal frame. The lifting cylinder is connected to the vertical base, and a second slider on the vertical mounting base cooperates with a second slide rail on the portal frame.
[0018] Preferably, a wire rod support frame is provided on the mounting platform located in front of the wire rod limiting mechanism.
[0019] Compared with the prior art, the advantages of the present invention are as follows: The tape winding mechanism of this invention has a circular winding gear that drives the tape roll to rotate during its rotation. The tape on the roll is released from its tension, allowing the bob to pass through the winding gear. During this process, a winding motor drives the winding gear to rotate, thereby achieving tape wrapping around the end of the bob and ensuring consistent winding force during the tape winding process, thus guaranteeing the winding effect. This invention also includes a bob limiting mechanism installed at the front of the tape winding mechanism to prevent the bob from becoming skewed during winding and affecting the winding process. A bob support mechanism is installed at the rear of the tape winding mechanism to provide support for the bob and ensure continuous tape winding on the bob. Attached Figure Description

[0032] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. These embodiments are implemented based on the technical solution of the present invention, and detailed implementation methods and specific operation processes are given. However, the scope of protection of the present invention is not limited to the following embodiments.
[0033] It should be noted that, in the description of this invention, relational terms such as “first” and “second” are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
[0034] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0035] like Figure 1-3 As shown, the present invention proposes a tape winding device for a stator coil production line, including a mounting platform 100, a bar limiting mechanism 200, a tape winding mechanism 300, and a bar support mechanism 400 arranged on the mounting platform 100 at the front and rear, and also includes a tape cutting mechanism 500 arranged in the tape winding mechanism 300.
[0036] Combination Figure 1-5 It is known that the tape winding mechanism 300 includes a stand 301 fixed on the mounting platform 100 and a belt drive mechanism set on the stand 301. The belt drive mechanism has a reduction ratio and includes a winding motor 303a set on the rear side of the stand 301, a drive gear (the drive gear and the winding motor 303a are connected) located on the front side of the stand 301, and a winding gear 303b (with teeth on the outer ring) set at the center of the stand 301. A rack belt 303d is wound between the drive gear and the winding gear 303b. The drive gear is a small gear and the winding gear 303b is a large gear to meet the tape winding requirements. A protective plate 304 is provided on the stand 301 corresponding to the drive gear to protect the drive gear and the rack belt 303d. To ensure smooth passage of the wire bar, the winding gear 303b is preferably a ring gear. The center hole of the stand 301 has four circumferentially distributed support bearings 303c. The inner ring of the winding gear 303b rolls with the support bearings 303c, which support the winding gear 303b and provide a mounting base for the winding gear 303b, ensuring the rotation operation of the winding gear 303b. A tape holder 302 is provided on the winding gear 303b for placing the tape roll.
[0037] The stand 301 of the present invention has a central hole and the winding gear 303b is a ring gear, ensuring that the wire bar can pass through the winding gear 303b and the stand 301. During operation, the winding motor 303a drives the winding gear 303b to rotate through the drive gear and the rack belt 303d. During this process, the winding gear 303b drives the tape holder 302 to rotate synchronously, thereby realizing the winding of tape on the wire bar.
[0038] Combination Figure 1-3It is understood that the bar limiting mechanism 200 includes a limiting power source, a pair of fixed seats 201 (fixed on the mounting platform 100) disposed on the front side of the upright 301, a bidirectional lead screw 202 rotatably disposed on the two fixed seats 201, and a pair of limiting components disposed on the bidirectional lead screw 202. The limiting components include a nut seat 203 screwed onto the bidirectional lead screw 202 and a limiting roller 205 vertically fixed to the nut seat 203. The two limiting rollers 205 are spaced apart to limit the bar. The limiting power source is connected to the bidirectional lead screw 202 for transmission, and the two limiting components are symmetrically disposed on the bidirectional lead screw 202. The limiting power source drives the bidirectional lead screw 202 to rotate, satisfying the opening and closing of the two limiting components, thereby satisfying the limiting requirements of bars of different widths.
[0039] During actual installation, the base plate of the fixed seat 201 has a first slide rail 206, and the bottom of each nut seat 203 is provided with a first slider that cooperates with the first slide rail 206 to ensure the linear reciprocating motion of each nut seat 203.
[0040] Combination Figure 3 As can be seen, the limiting power source includes a limiting motor 207a (fixed on the mounting platform 100 via a motor mount, and is a servo motor) and a first synchronous belt drive pair 207b (covered with a protective shell) driven by the limiting motor 207a. The driven wheel of the first synchronous belt drive pair 207b is installed at one end of the bidirectional lead screw 202, thereby realizing the transmission of power. The first synchronous belt of the first synchronous belt drive pair 207b is installed in the direction of the lead screw's movement, and the bidirectional lead screw 202 and the first synchronous belt are arranged at a 90-degree angle, realizing the transmission of power within a confined space.
[0041] The working process of the bar limiting mechanism 200 of the present invention is as follows: When there is no bar, the two limiting rollers 205 are in an open state. When the front end of the bar moves to this position, the limiting motor 207a drives the first synchronous belt transmission pair 207b to rotate, thereby transmitting power to the bidirectional lead screw 202 to rotate. The bidirectional lead screw 202 drives the two limiting rollers 205 to move towards each other, thereby limiting the bar. The upper part of the limiting roller 205 can roll, which can reduce the friction between the limiting roller and the bar and reduce the impact on the bar.
[0042] The present invention installs a bar limiting mechanism 200 in front of the tape winding mechanism 300 to limit the bar and prevent the bar from deviating during movement, which would affect the winding quality. In addition, the spacing between the limiting rollers 205 can be flexibly adjusted to limit bars of different widths, thereby meeting the wrapping requirements of bars of different specifications.
[0043] Combination Figure 1-7It is known that the tape cutting mechanism 500 includes a mounting base 501 horizontally fixed to the rear side of the stand 301 and a tape auxiliary pasting structure, a tape pressing structure, and a tape cutting structure arranged sequentially from left to right. A mounting shaft 506 located in the center hole of the stand 301 is installed on the front side of the mounting base 501. The tape auxiliary pasting structure includes a third gear 502a rotatably mounted on the mounting shaft 506 and a third rack 503b located below the third gear 502a. The third rack 503b is horizontally arranged along the length of the wire bar. The tape auxiliary pasting structure also includes a third cylinder 503c horizontally arranged at the bottom of the mounting base 501. The third cylinder 503c is connected to the third rack 503b in a transmission connection. A second pressing plate 502d is fixedly connected to the third gear 502a. When the piston rod of the third cylinder 503c extends or retracts, it drives the third rack 503b to move horizontally, causing the third gear 502a to rotate relative to the mounting shaft 506. This allows for free switching between the second top pressure plate 502d's retraction and lifting to assist in pasting. It not only assists in pasting the free end of the tape and the wire rod, but also retracts during the winding process to avoid the tape and ensure the winding of the wire rod.
[0044] Combination Figure 6-7 It is known that the tape pressing structure includes a first cylinder 503c, a horizontally arranged first rack 503b, and a first gear 503a rotatably arranged on the mounting shaft 506. The first rack 503b and the third rack 503b are arranged in a row. The first gear 503a is located above the first rack 503b and meshes with the first rack 503b. The first cylinder 503c is horizontally arranged and connected to the first rack 503b. A first pressing plate 503d is fixedly connected to the first gear 503a. The first cylinder 503c drives the first rack 503b to move horizontally, causing the first rack 503b to drive the first pressing plate 503d to rotate. During cutting, it can lift up and press down the tape to assist in cutting. Combination Figure 6-7 It is known that the tape cutting structure includes a second cylinder 504c, a horizontally arranged second rack 504b, and a second gear 504a rotatably arranged on the mounting shaft 506. The second gear 504a is located above the second rack 504b and meshes with the second rack 504b. The horizontally arranged second cylinder 504c is connected to the second rack 504b. A cutting plate 504d with a cutter 504e is fixedly connected to the second gear 504a. The second cylinder 504c drives the second rack 504b to move horizontally, causing the cutting plate 504d to rotate. The first cylinder 503c, the second cylinder 504c, and the third cylinder 503c are fixedly installed at the bottom of the mounting base 501. The first cylinder 503c is located behind the first rack 503b, the second cylinder 504c is located behind the second rack 504b, and the third cylinder 503c is located behind the third rack 503b, ensuring the straight reciprocating motion of each rack.
[0045] Combination Figure 3 , 6 As shown in -7, three T-shaped brackets 505 are arranged side by side at the lower part of the stand 301 (the bottom of the brackets is fixed to the stand 301). The first rack 503b, the second rack 504b and the third rack 503b are respectively located on the horizontal support part of the bracket 505 corresponding to them. When the rack is under force, it can move back and forth horizontally on the horizontal support part.
[0046] Combination Figure 8 It can be seen that the free end of the second top pressure plate 502d extends toward the free end of the first top pressure plate 503d, and the free end of the cutting plate 504d extends toward the free end of the first top pressure plate 503d. The first top pressure plate 503d has a T-shaped structure and is located above the cutting plate 504d. The free end of the second top pressure plate 502d is provided with a first sponge 502e to assist in protecting the wire rod during pasting and reducing damage to the wire rod. A second sponge 504f (cutting plate...) is provided on the cutting plate 504d at the position corresponding to the first top pressure plate 503d. Part 504d is located below the first top pressure plate 503d. The cutter 504e is fixedly connected to the cutting plate 504d near the second sponge 504f. The cutter 504e and the first top pressure plate 503d are designed to be offset left and right. The second sponge 504f avoids the cutting plate 504d and the first top pressure plate 503d from making hard contact. During cutting, the second sponge 504f is compressed, causing the cutter 504e to lift up and cut the tape. The cutting part of the cutter 504e adopts a serrated structure to ensure fast cutting of the tape.
[0047] In this invention, both top pressure plates and the cutting plate 504d rotate around the mounting shaft 506. When the free end falls back to the lower limit position, it can avoid the tape and allow the tape to wrap around the wire rod. When cutting or assisting in pasting is required, the top pressure plate and the cutting plate 504d can be lifted upward to press the tape upward, which facilitates pasting and cutting.
[0048] Combination Figure 1-3As shown in 10-12, the bar support mechanism 400 is located behind the support 301 and includes a support unit 401 mounted on the mounting platform 100, a power unit 402 mounted above the support unit 401, and a lifting power mechanism 403 that drives the power unit 402 to move up and down. The support unit 401 includes a plurality of conveying rollers arranged at intervals to provide rigid support for the bar. The power unit 402 provides power for the bar to move forward. The lifting power mechanism 403 includes a portal frame 403a mounted on the mounting platform 100, a lifting power source fixed to the portal frame 403a, and a vertical base 403c driven by the lifting power source to move up and down. The vertical base 403c is located above the support unit 401. The power unit 402 includes a motor reducer 402a and a second synchronous belt drive pair 402b driven by the motor reducer 402a. The second synchronous belt drive pair 402b is located above the feed end of the upper conveying unit. When the bar moves to the lower conveying unit, the lifting power mechanism 403 drives the power unit 402 to descend, so that the second synchronous belt of the second synchronous belt drive pair 402b acts on the upper surface of the bar, providing forward moving force for the bar conveying.
[0049] The support unit 401 in this invention provides support for the wire bar. The support unit 401 adopts a conveying roller. When subjected to the external force applied by the second synchronous belt, the wire bar moves forward on the support unit 401, thereby realizing the continuous winding of the release belt and the continuous winding of the tape, improving the winding efficiency, and thus improving the production efficiency of the coil.
[0050] Combination Figure 10-11 It is known that the lifting power source includes a lifting cylinder 403b vertically mounted on the crossbeam of the portal frame 403a, and the lifting cylinder 403b is connected to the vertical mounting base 501; a pair of second slide rails are symmetrically arranged on the legs of the portal frame 403a, and two second slide rails are provided on the left and right sides of the vertical base 403c for sliding engagement, providing support for the power unit 402, ensuring the stable lifting and lowering of the power unit 402, and ensuring the flexible adjustment of the height of the power unit 402. During operation, when the bar moves onto the support unit 401, the lifting power mechanism 403 drives the power unit 402 to descend, so that the second synchronous belt of the second synchronous belt transmission pair 402b acts on the upper surface of the bar; the motor is started, and the second synchronous belt transmits power to the bar, causing the bar to move forward on the support unit 401.
[0051] Combination Figure 1 It can be seen that a wire rod support frame 600 is provided on the mounting platform 100 located in front of the wire rod limiting mechanism 200. The wire rod support frame has a portal-shaped structure and provides support for the wire rod.
[0052] The tape cutting mechanism 500 of the present invention is installed at a height lower than the wire rod. During the tape winding process, the tape will inevitably pass under the wire rod (wrapped with release tape). During winding, the initial position of the tape holder 302 is located at the lower left of the stand 301 (see figure). The tape winding process in the present invention is as follows: When the wire rod passes the tape winding mechanism 300, the free end of the tape is manually pulled to the right a certain length from below the wire rod. The first top pressure plate 503d and the second top pressure plate 502d (as shown) Figure 9 The free end of the tape (see schematic diagram a) is raised to a certain height to support the pulled-out tape; the tape winding mechanism 300 is activated to wind the tape, and during winding, the second top pressure plate 502d is raised upward (see schematic diagram a). Figure 9 (b) The tape is stuck to the bottom of the bar, and the winding motor 303a drives the winding gear 303b to rotate clockwise. During the winding process, the bar is manually or by using the mechanical gripper in the production line to provide initial power until the front end of the bar reaches the bar support mechanism 400. Then the power unit 402 is lowered into place and the bar is moved forward by the power unit 402. During the rotation of the winding gear 303b, to avoid the conveyor belt, the second cylinder 504c, the first cylinder 503c, and the third cylinder 503c are activated sequentially, causing the cutting plate 504d, the first pressure plate 503d, and the second pressure plate 502d to be arranged side by side after retraction (the specific positions are as follows). Figure 9 As shown in c), the wires fall back to their lowest positions to ensure continuous wrapping of the tape on the wire bar and avoid wrapping the top pressure plate and cutting plate 504d. After the specified number of turns, when the winding gear 303b drives the tape holder 302 to rotate from the lower right to the lower left of the stand 301, the first cylinder 503c actuates as the tape passes above the first pressure plate 503d, causing the first pressure plate 503d to lift upwards and press the tape. Then, the second cylinder 504c actuates, causing the cutting plate 504d to lift upwards, and the tape is cut by the cutter 504e, completing the tape winding at the front end of the bar. When the tail end of the bar passes the tape winding mechanism 300, the tape is wound and cut according to the above steps. During this process, when the front end of the bar reaches the bar support mechanism 400, the power provided by the power unit 402 makes the bar move forward at a constant speed, satisfying the tape winding requirements at both the front and tail ends of the bar.
