Abstract

This invention relates to the technical field of guide bar wrapping, specifically to an automatic wrapping device and method for rotor guide bars. The wrapping device includes a carrying frame, a fixing mechanism, a supporting mechanism, a winding mechanism, and a feeding component. After the operator fixes the guide bar to the fixing mechanism, the wrapping material is placed on the feeding component, and then the winding mechanism is started to wrap the guide bar. Due to the supporting mechanism, some irregularly shaped guide bars can also be wrapped. Since different wrapping densities are required, the height of the power component on the winding mechanism is adjusted to change the travel speed of the winding mechanism, thereby achieving different width wrapping requirements. At the same time, the equipment can also wrap multiple materials simultaneously, which has good practicality and economy, and is beneficial to the promotion and use of the equipment.

Description

Technical Field

[0001] This invention relates to the technical field of guide bar wrapping, and more specifically to an automatic wrapping device and method for rotor guide bars. Background Technology

[0002] Rotor bars are a key component of motor rotors, serving as conductive materials connecting the rotor and the power source to transfer electrical energy. These bars possess high wear resistance, high temperature resistance, corona resistance, and high voltage resistance; they maintain stable electrical performance, high conductivity, low heat generation, and high efficiency even under long-term high-speed motor operation. The quality of the rotor bars directly affects the motor's performance and lifespan. They are widely used in wind power motors, large-scale mechanical engineering, and other fields. Due to varying operating environments, rotor bars typically require rotational wrapping with insulating materials. However, this wrapping process is often difficult to mass-produce, and the need for bending the bars makes the wrapping process challenging. Furthermore, manual wrapping has low standardization, hindering safe application in the field. Summary of the Invention

[0017] In one embodiment, a wrapping method for an automatic wrapping device suitable for rotor guide bars is also included, the specific wrapping method being:

[0018] S1, after the guide bar passes through the winding mechanism, one end is inserted into the buffer to fix it;

[0019] S2, Flip the fixing piece to secure the guide bar to the fixing mechanism and prevent slippage;

[0020] S3, flip the power component so that it contacts both sides of the guide bar;

[0021] S4, place the wrapped material after placing it on the feeding device, and fix one end to the wrapping end of the guide strip;

[0022] S5, start the wrapping device to wrap, cut the wrapping material after completion and flip the power device to detach from the guide strip, then flip the fixing device to remove the guide strip, and the wrapping tape is completed.

[0023] The beneficial effects of this invention are as follows: This invention is an automatic wrapping device and method suitable for rotor guide bars, applicable to simultaneous wrapping of multiple materials and adjustment of wrapping density to accommodate partial bending. The specific implementation method is as follows:

[0024] The operator first passes the metal rotor guide bar through the rotating disc and then continues it between the elliptical clamping plates. The inclined plates on both sides compress the telescopic spring, fixing the guide bar and preventing it from sliding. Because the elliptical clamping plates are elliptical in shape, the guide bar can still be fixed for a certain distance after it is inserted into the elliptical clamping plates, preventing the metal rotor guide bar from bending and detaching from the fixation. Then, the rotating block is flipped and rotated so that the limiting groove engages with the surface of the guide bar. With the cooperation of the buffer elliptical clamping plates, when the guide bar bends downward under the action of gravity, it generates a lateral shear force on the rotating block, causing the auxiliary roller and the rotating block to tightly clamp the metal guide bar, preventing the rotating block from flipping and detaching from the guide bar, thus completing the fixation of the guide bar.

[0025] Then, the flipping block is flipped, and the trapezoidal rotating column is clamped on both sides of the metal guide strip. The torsion spring keeps the side rotating block in control, controlling the trapezoidal rotating column to fit the guide strips of different widths. Then, the motor is started to rotate the trapezoidal rotating column, which in turn drives the flipping block to pull the fixed ring to move. At the same time, the rotating motor is started, and the meshing gear on the rotating motor drives the rotating disk to rotate circumferentially on the fixed ring. This further drives the wrapping tape on the feeding device to wrap the guide strip, achieving standardized wrapping of the guide strip. After completion, the guide strip is cut off, and the flipping block is manually flipped to detach the guide strip, thus completing the wrapping.

[0026] To address the partially bent guide bar, the trapezoidal rotating column adheres to both sides of the guide bar during the movement of the support slider. The different travel lengths at the bends cause the support slider to slide along the guidance of the second slide rod. While wrapping the guide bar in the straight section, it slides along the guidance of the first slide rod. Through the sliding cooperation between the second slide rod and the first slide rod in the second sliding groove and the first sliding groove, the winding mechanism achieves wrapping at a certain position within the loading frame.

[0027] Since the density of the strapping is controlled by the application scenario of the guide bar, the height of the traveling contact wheel in contact with the guide bar surface is adjusted, and the position of the rotating threaded adjustment shaft on the main drive block is adjusted. This causes the sliding pin on the main drive block to slide closer to the flipping block, changing the position of the trapezoidal rotating column clamping the two sides of the guide bar. Since the rotation speed of the trapezoidal rotating column is fixed, different rotation radii drive the winding mechanism to produce different travel speeds, thus completing the density change of the strapping. After the strapping is completed, the flipping block is flipped, and the flipping block is fixed by the pushing force of the limit spring on the sliding limit block.

[0028] Due to the different required strapping thicknesses, multiple straps are needed for simultaneous strapping. After placing the required number of feeders in the placement holes and fixing them, the tape ring is inserted around the feed tube and fixed by the inclined assist block. After the tape is used up, the extrusion plate moves inward, compressing the pressure spring and simultaneously pushing the extrusion movable plate on the elastic plate inward, causing the inclined assist block to gather inward, and the tape ring can be freely disassembled.

[0029] The device has a simple structure and controls its travel speed, density, and thickness of the strapping through a simple clamping method. It is also quite practical when strapping partially bent guide strips. The strapping effect is more standardized than manual strapping, which helps ensure the safe use of guide strips and is beneficial to the promotion of the device. Attached Figure Description

[0044] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the invention and are not intended to limit the invention; that is, the described embodiments are merely some embodiments of the invention, and not all embodiments. The components of the embodiments of the invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0045] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0046] The following is combined Figure 1-12 This invention describes a specific embodiment of an automatic wrapping device for rotor guide bars, comprising:

[0047] Reference Figure 1 As shown, the loading frame 1 is used to support the equipment; the loading frame 1 is a general product, mainly used to fix or support various structural parts. The attached drawing adopts an exaggerated drawing style to show its structure, not the actual scale.

[0048] Reference Figure 3 , 4 As shown, the fixing mechanism 2 includes a buffer and a fixing component to assist in fixing the guide bar. The buffer includes two sets of cross plates 21, which are fixedly connected to one side of the loading frame 1. The two sets of cross plates 21 are symmetrically arranged. A beveled plate 22 is provided on the opposite side of the cross plates 21. Several telescopic springs 23 are provided between the beveled plate 22 and the cross plates 21. Rotating fixing rods 24 are also provided at both ends of the short rods of the two sets of cross plates 21. The two ends of the rotating fixing rods 24 are fixedly connected to the cross plates 21. An elliptical clamping plate 25 is provided in the middle of the rotating fixing rod 24. The elliptical clamping plate 25 is teardrop-shaped. The structure has an elliptical pallet 25 with its tip away from the loading frame 1 that is fixedly connected to the cross plate 21. The fixing component includes two sets of support rods 28, which are fixedly connected to the side of the loading frame 1 away from the buffer. A roller rod 271 is provided between the two sets of support rods 28. An auxiliary roller 27 is provided in the middle of the roller rod 271. A rotating and flipping block 26 is also provided on the roller rod 271. The rotating and flipping block 26 has a C-shaped structure. One end of the rotating and flipping block 26 has an L-shaped limiting groove 261. One end of the rotating and flipping block 26 is rotatably connected to both sides of the auxiliary roller 27 on the roller rod 271.

[0049] In practice, the metal rotor guide bar continues to pass between the elliptical clamping plates 25 after passing through the rotating disk 41. It presses the inclined plates 22 on both sides to compress the telescopic spring 23, thus fixing the guide bar and preventing it from sliding. Since the elliptical clamping plate 25 has an elliptical structure, it can still be fixed within a certain distance after passing through the elliptical clamping plate 25, preventing the metal rotor guide bar from bending and causing it to fall out of the fixed position. Then, the rotating flipping block 26 is flipped and rotated, so that the limiting groove 261 engages with the surface of the guide bar. With the cooperation of the buffer elliptical clamping plate 25, when the guide bar bends downward under the action of gravity, it generates a lateral shear force on the rotating flipping block 26, so that the auxiliary roller 27 and the rotating flipping block 26 tightly clamp the metal guide bar, making it impossible for the rotating flipping block 26 to flip and fall out of the guide bar, thus completing the fixing of the guide bar.

A limiting spring 442 is provided between the sliding limiting block 441 and the recess connecting block 44. The end of the sliding limiting block 441 away from the recess connecting block 44 is attached to the top of the flipping block 443. A main driving block 444 is provided at the end of the flipping block 443 away from the sliding limiting block 441. Several sliding pins 445 are provided on the main driving block 444. The sliding pins 445 pass through and are slidably connected to the end of the flipping block 443 away from the sliding limiting block 441.

A motion motor 447 is also provided on the side rotating block 446, and the motion motor 447 is fixedly connected to the side rotating block 446. An extension rod 44701 is provided on the rotating shaft of the motion motor 447, passing through the middle of the side rotating block 446. A trapezoidal rotating column 448 is provided at the end of the extension rod 44701 away from the motion motor 447. The power component also includes a threaded adjusting shaft 461, which is rotatably connected to the middle of the main drive block 444. A travel contact wheel 46 is provided at the end of the threaded adjusting shaft 461 away from the notched connecting block 44. Several feeding components 5 are placed on the winding component. (Refer to...) Figure 11 , 12As shown, the feeding component 5 includes an inlet pipe 51, on which a placement groove 511 is provided. The inlet pipe 51 passes through the placement hole 43 and slides into the placement groove 511 by a limiting block 431. A feeding pipe 52 is provided on the side of the inlet pipe 51 away from the placement groove 511. Several fixing grooves 521 are provided on the feeding pipe 52. An elastic plate 53 is provided in the fixing groove 521. One end of the elastic plate 53 is fixedly connected to the fixing groove 521.

A pressure spring 541 is also provided in the inner cavity of the feeding pipe 52. A pressing plate 54 is provided at the end of the pressure spring 541 away from the inlet pipe 51.

[0052] In practice, the height of the traveling contact wheel 46 against the guide strip surface is adjusted, and the position of the rotating threaded adjustment shaft 461 on the main drive block 444 is rotated. This causes the sliding pin 445 on the main drive block 444 to slide closer to the flipping block 443, changing the position of the trapezoidal rotating column 448 clamping the two sides of the guide strip. Since the rotation speed of the trapezoidal rotating column 448 is fixed, different rotation radii drive the winding mechanism 4 to produce different traveling speeds, thus completing the density change of the wrapping tape. After the wrapping tape is completed, the flipping block 443 is flipped. The flipping block 443 is fixed by the pushing force of the limiting spring 442 on the sliding limiting block 441.

[0053] Beneficially, it also includes a wrapping method for an automatic wrapping device suitable for rotor guide bars: the specific wrapping method is as follows:

[0054] S1, after the guide bar passes through the winding mechanism 4, one end is inserted into the buffer to fix it;

[0055] S2, flip the fixing piece to fix the guide bar to the fixing mechanism 2 to prevent slippage;

[0056] S3, flip the power component so that it contacts both sides of the guide bar;

[0057] S4, after placing the wrapped material on the feeding part 5, fix one end to the wrapping end of the guide strip;

[0058] S5, start the wrapping device to wrap, cut the wrapping material after completion and flip the power device to detach from the guide strip, then flip the fixing device to remove the guide strip, and the wrapping tape is completed.

[0059] Working principle of this invention:

[0060] The operator first passes the metal rotor guide bar through the rotating disc 41 and then continues to pass it between the elliptical clamping plates 25. The inclined plates 22 on both sides are pressed to compress the telescopic spring 23, fixing the guide bar and preventing it from sliding. Since the elliptical clamping plate 25 has an elliptical structure, it can still be fixed for a certain distance after passing through the elliptical clamping plate 25, preventing the metal rotor guide bar from bending and detaching from the fixation. Then, the rotating flipping block 26 is flipped and rotated, so that the limiting groove 261 engages with the surface of the guide bar. With the cooperation of the buffer elliptical clamping plate 25, when the guide bar bends downward under the action of gravity, it generates a lateral shear force on the rotating flipping block 26, so that the auxiliary roller 27 and the rotating flipping block 26 tightly clamp the metal guide bar, preventing the rotating flipping block 26 from flipping and detaching from the guide bar, thus completing the fixation of the guide bar.

[0061] Then, the flipping block 443 is flipped, and the trapezoidal rotating column 448 is clamped on both sides of the metal guide strip. The torsion spring 451 keeps the side rotating block 446 controlling the trapezoidal rotating column 448 to fit the guide strips of different widths. Then, the motion motor 447 is started to rotate the trapezoidal rotating column 448. The trapezoidal rotating column 448 drives the flipping block 443 to pull the fixed ring 37 to move. At the same time, the rotation motor 361 is started. The meshing gear 362 on the rotation motor 361 drives the rotating disk 41 to rotate circumferentially on the fixed ring 37, which further drives the wrapping tape on the feeding part 5 to wrap the guide strip, realizing the standardized wrapping of the guide strip. After completion, the guide strip is cut off, and the flipping block 26 is manually flipped to release the guide strip, thus completing the wrapping.

[0062] To address the partially bent guide strip, the trapezoidal rotating column 448 adheres to both sides of the guide strip during the movement of the support slider 34. The different travel lengths at the bends cause the support slider 34 to slide along the guide of the second slide rod 342. While wrapping the guide strip in the straight section, it slides along the guide of the first slide rod 341. Through the sliding cooperation between the second slide rod 342 and the first slide rod 341 in the second sliding groove 33 and the first sliding groove 32, the winding mechanism 4 achieves wrapping at a certain position within the carrying frame 1.

[0063] Since the density of the strapping tape is controlled by the application scenario of the guide strip, the height of the traveling contact wheel 46 in contact with the guide strip surface is adjusted, and the position of the rotating threaded adjustment shaft 461 on the main drive block 444 is rotated. This causes the sliding pin 445 on the main drive block 444 to slide closer to the flipping block 443, changing the position of the trapezoidal rotating column 448 clamping both sides of the guide strip. Since the rotation speed of the trapezoidal rotating column 448 is fixed, different rotation radii drive the winding mechanism 4 to generate different travel speeds, thus completing the density change of the strapping tape. After the strapping tape is wrapped, the flipping block 443 is flipped. The flipping block 443 is fixed by the pushing force of the limiting spring 442 on the sliding limiting block 441.

[0064] Due to the different required strapping thicknesses, multiple straps are needed for simultaneous strapping. After placing the required number of feed pieces 5 into the placement hole 43 and fixing them, the strip ring is inserted around the feed tube 52 and fixed by the inclined assist block 531. After the strip is used up, the extrusion plate 54 moves inward, pressing the pressure spring 541 and simultaneously pushing the extrusion movable plate 532 on the elastic plate 53 to gather inward, causing the inclined assist block 531 to gather inward, and the strip ring can be freely disassembled.
