Description

Technical Field

[0001] This utility model belongs to the field of transformer parts manufacturing technology, specifically relating to an automatic processing equipment for soft corner rings used on power transformer coils. Background Technology

[0002] In transformer manufacturing, to prevent creepage between coils or coil windings and to improve the electric field distribution at the coil ends, soft angle rings are used during coil winding to increase the creepage distance. Soft angle rings are widely used in coil winding. Transformer soft angle rings can significantly enhance the creepage distance at the coil ends, while improving the electric field distribution at the coil ends and balancing the field strength. Soft angle rings can also shorten the insulation distance, making the transformer structure more compact and saving costs. Furthermore, they can ensure the unobstructed axial oil passages of the high-voltage coil, improving heat dissipation.

[0003] The production of soft corner rings typically uses long strips of cardboard as raw material, which are then processed through corrugation and bending. Chinese patent CN218447558U discloses a bending machine for insulating materials used in transformer production. During operation, the insulating material is manually placed in the processing position according to size requirements, and bending is achieved by rotating a movable plate. Currently, both domestic and international manufacturers use similar human-machine collaborative methods for producing soft corner rings. However, the traditional processing method of manually operating mechanical equipment to corrugate and bend the cardboard results in low production efficiency. For smaller soft corner rings, manual corrugation and bending pose safety hazards, and the produced soft corner rings have poor precision and large manufacturing tolerances. If the quality of the soft corner ring fails to meet design requirements, it cannot achieve the purpose of protecting the coil, easily causing wire creep, insulation breakdown, and short circuit faults.

Detailed Implementation

[0035] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0036] like Figure 1-16 As shown, the automatic soft corner ring processing equipment includes a storage rack 6, a corrugating, bending, and unloading rack 7, and a finished product rack arranged sequentially from front to back (referring to the direction of cardboard movement). The storage rack 6, the corrugating, bending, and unloading rack 7, and the finished product rack are all equipped with height-adjustable feet at their bottoms. The flat structure at the bottom of the adjusting feet rests on the workshop floor. These adjusting feet allow for easy height adjustment of each component, while ensuring the stability of the fully automatic processing equipment during operation. The rear section of the corrugating, bending, and unloading rack 7 is designed with hinged cabinet doors. The space enclosed by these doors serves as an electrical cabinet, ensuring the safety of the electrical equipment installation and use.

[0037] The top of the storage rack 6 is a flat plate structure, and the feeding mechanism 1 and several storage mechanisms 5 are fixedly installed on the storage rack 6. Each storage mechanism 5 includes a pair of parallel side plates along its length and a sealing plate located at the rear end of the storage mechanism 5 along its width. The front end of the storage mechanism 5 is open, and the spacing between the pair of side plates is adjustable to accommodate cardboard of different widths. The feeding mechanism 1 includes a feeding robot, a feeding conveyor belt 11, and a feeding motor 12. The feeding conveyor belt 11 is located to the side of the storage mechanism 5, and its length is parallel to that of the storage mechanism 5. The control mechanism 4 controls the operation of the feeding conveyor belt 11 by controlling the feeding motor 12. The loading robot is fixedly installed above the storage mechanism 5 and the loading conveyor belt 11. After the loading robot grabs the cardboard from the storage mechanism 5, it places the cardboard onto the loading conveyor belt 11. The loading robot includes a loading support rod 15, a loading robot bracket 18, mounting rods 19, and an electric suction cup 20. The three-dimensional loading robot bracket 18 is fixedly installed above the storage rack 6. The horizontal loading support rod 15 is movably installed on the three-dimensionally movable parts of the loading robot bracket 18. The three-dimensional movement of the loading support rod 15 is achieved by controlling the robot motor through the control mechanism 4. The top ends of several mounting rods 19 are evenly distributed and fixedly installed on the loading support rod 15. The electric suction cup 20 is fixedly installed at the bottom end of the mounting rod 19. The electric suction cup 20 is controlled by the control mechanism 4 to grab or place the cardboard. According to the production process requirements, several long strips of cardboard raw materials are stacked in one go into the cavity formed by a pair of side plates and the sealing plate at the rear end of the storage mechanism 5. The feeding mechanism 1 is automatically controlled by the control mechanism 4, which can achieve uninterrupted continuous feeding without manual intervention.

[0038] The top of the corrugating, bending, and unloading rack 7 is a flat plate structure. The corrugating mechanism 9, bending mechanism 2, and unloading mechanism 3 are sequentially fixed above the corrugating, bending, and unloading rack 7 from front to back. The control mechanism 4 is fixedly installed above the unloading mechanism 3 via an L-shaped mounting bracket. The corrugating mechanism 9 is an existing product, and its corrugating rollers are made of stainless steel or non-metallic insulating materials. The bending mechanism 2 includes a housing shell, and a bending roller assembly mechanism is installed inside the housing shell. The bending roller assembly mechanism includes several sets of matching bending roller sets and clamping roller sets. The housing shell ensures the operational safety of the bending roller sets and clamping roller sets. A cardboard inlet is located at one end of the outer casing near the corrugating mechanism 9, and a soft corner ring outlet is located at the other end near the unloading mechanism 3. A limit mechanism 21 is installed at the front end of the cardboard inlet, and an upwardly inclined pressure roller 10 is installed at the rear end of the soft corner ring outlet. The bottom height of the pressure roller 10 is less than the height of the right-angle plate of the soft corner ring. If the cardboard is only bent to 90 degrees for discharge, it will spring back at a certain angle after discharge. Therefore, a pressure roller 10 is installed at the outlet to press the soft corner ring to an angle smaller than 90 degrees. This ensures that the soft corner ring maintains a 90-degree angle after springback, and the excessive bending offsets the springback angle of the cardboard.

[0039] The limiting mechanism 21 includes an upper limiting plate 22 and a lower limiting plate 23 arranged in parallel. The upper limiting plate 22 and the lower limiting plate 23 are fixedly installed on the outer shell of the box. The distance between the upper limiting plate 22 and the lower limiting plate 23 can be flexibly adjusted according to the different thicknesses of the cardboard. Adjustable slots are formed at both ends of the lower limiting plate 23. The length direction of the adjustable slots is consistent with the width direction of the cardboard. A mounting base 24 is fixedly installed at the outer end of the adjustable slot. An adjusting screw 25 passes through the mounting base 24 and is threadedly connected to the mounting base 24. A limiting strip 26 is fixedly installed at the adjacent ends of a pair of adjusting screws 25. The front end of the limiting strip 26 is bent outward to facilitate the entry of the cardboard into the bending mechanism 2. By flexibly adjusting the distance between the pair of limiting strips 26 through the adjusting screws 25, the limiting mechanism 21 can adapt to cardboard of different widths. By setting the limiting mechanism 21, different cardboard raw material sizes can be adapted to ensure that the cardboard is fed evenly into the bending mechanism 2. Furthermore, the bending position of the cardboard can be flexibly adjusted through the limiting mechanism 21, enabling the processing of soft corner rings with different process requirements.

[0040] The bending mechanism 2 includes a bending roller assembly, a clamping roller assembly, and a bending clamping motor 27, which are fixedly installed on the corrugating and bending and unloading rack 7. The bending clamping motor 27 is a dual-output shaft motor including a clamping shaft 34 and a bending shaft 35. The clamping shaft 34 is connected to the clamping roller assembly via a clamping chain 36 to drive the clamping roller assembly to rotate. The bending shaft 35 is connected to the bending roller assembly via a bending chain 37 to drive the bending roller assembly to rotate. The bending roller assembly includes bending roller assembly 28, bending roller assembly 29, and bending roller assembly 30 arranged sequentially from front to back. The clamping roller assembly includes clamping roller assembly 31, clamping roller assembly 32, and clamping roller assembly 33 arranged sequentially from front to back. Clamping roller assembly 31, clamping roller assembly 32, and clamping roller assembly 33 are respectively located in front of bending roller assembly 28, bending roller assembly 29, and bending roller assembly 30. The cardboard passes through clamping roller assembly 31, bending roller assembly 28, clamping roller assembly 22, bending roller assembly 29, clamping roller assembly 33, and bending roller assembly 30 in sequence.

[0041] The clamping roller assembly 31 includes a pair of parallel clamping rollers of the same length. The clamping roller assembly 32 and clamping roller assembly 33 each include a pair of parallel clamping rollers of different lengths. The upper clamping roller of clamping roller assembly 32 is shorter than the lower clamping roller, and the upper clamping roller of clamping roller assembly 33 is shorter than the lower clamping roller. The bending roller assembly 28 and bending roller assembly 29 each include a pair of relatively parallel frustum-shaped bending rollers. The upper bending roller of bending roller assembly 28 and the lower bending roller of bending roller assembly 29 have adjacent overlapping inclined surfaces. After the bending section of the cardboard passes through the inclined surface gap between the upper bending roller and the lower bending roller, it is bent to form a bending structure of less than or equal to 30°. The upper bending roller of bending roller assembly 29 and the lower bending roller of bending roller assembly 29 have adjacent overlapping inclined surfaces. After the cardboard bends through the sloping gap between the upper bending roller and the lower bending roller, it is bent to form a bending structure of less than or equal to 60°. The bending roller assembly 30 includes a pair of relatively parallel disc-shaped bending rollers. The lower end of the upper bending roller and the upper end of the lower bending roller are adjacent and overlap. After the cardboard bends through the gap between the upper bending roller and the lower bending roller, it is bent to form a bending structure of 90°.

[0042] The feeding mechanism 3 includes a feeding motor 13 and a feeding conveyor belt 17. The feeding motor 13 and the feeding conveyor belt 17 are fixedly installed above the corrugating, bending and feeding frame 7. The length direction of the feeding conveyor belt 17 is consistent with the forward direction of the soft corner ring. The feeding end of the feeding conveyor belt 17 is located below the pressure roller 10, and the discharging end of the feeding conveyor belt 17 is located above the finished product storage bin 8. A downward inclined slope structure is provided between the discharging end of the feeding conveyor belt 17 and the finished product storage bin 8. The feeding motor 13 and the feeding conveyor belt 17 are controlled to run automatically by the control mechanism 4, which can realize the continuous feeding of finished soft corner rings without manual intervention and stacking them in the finished product storage bin 8.

[0043] The finished product rack has a pair of parallel finished product storage bin tracks 16 fixedly installed on its upper surface at a certain distance. The finished product storage bin 8 is a cuboid box with a closed bottom and an open top. The bottom upper surface of the finished product storage bin 8 is machined with several positive V-shaped or inverted V-shaped structures that match the soft corner rings, so that the soft corner rings can be stably stacked in the finished product storage bin 8. The two ends of the finished product storage bin 8 in the width direction are slidably installed on the finished product storage bin tracks 16. The length direction of the finished product storage bin tracks 16 is consistent with the width direction of the finished product storage bin 8, and the length direction of the finished product storage bin 8 is consistent with the length direction of the soft corner rings. The finished product storage motor 14 is fixedly installed on the side of the finished product rack. The rotating shaft of the finished product storage motor 14 is threadedly connected to the bottom middle position of the finished product storage bin 8. When a row of finished soft corner rings is stacked, the finished product storage motor 14 is automatically operated by the control mechanism 4, which enables the finished product storage bin 8 to move horizontally along the width direction, so that the empty storage position in the finished product storage bin 8 is automatically positioned, realizing the uninterrupted and continuous reception and storage of finished soft corner rings without manual intervention.

[0044] Control unit 4 can use Siemens or equivalent control equipment, including: PLC controller, touch screen, intermediate relays, miniature circuit breakers, and 24V DC power supply. To facilitate future equipment expansion, the PLC controller has 10% reserved I / O points.

[0045] The automatic soft corner ring processing equipment described in this embodiment of the invention only requires manual handling of the cardboard raw materials for making soft corner rings, which are then neatly arranged and stacked in the storage mechanism 5. The control mechanism 4 sets the movement rhythm and distance of the finished product storage bin 8. After powering on the automatic processing equipment, the cardboard feeding, cardboard corrugation, cardboard bending, finished soft corner ring unloading, and finished soft corner rings are automatically stacked and stored in the finished product storage bin 8. Finally, the processed soft corner rings are packaged and sorted by manual handling, and then transported by AGV trolleys. The remaining steps do not require manual operation, which greatly saves labor costs and reduces safety hazards.

[0046] In this embodiment of the utility model, all technical features not described in detail are existing technologies or conventional technical means, and will not be repeated here.
