Description

Technical Field

[0001] The present invention belongs to the technical field of transformer accessories production, and in particular relates to a fully automatic processing device and a processing method for soft angle rings used on power transformer coils. Background Art

[0002] During transformer manufacturing, soft angle rings are often added during the coil winding process to prevent creepage between coils or coils and to improve the electric field distribution at the coil ends. These rings are widely used in coil winding. They significantly increase creepage distance at the coil ends, improve the electric field distribution at the coil ends, and balance the field strength at the coil ends. They also shorten insulation distances, making the transformer structure more compact and cost-saving. They also ensure unobstructed axial oil passages in the high-voltage coils, improving heat dissipation.

[0003] Soft angle rings are usually made from long strips of cardboard as raw materials, which are then corrugated and processed through processes such as bending. Chinese patent CN218447558U discloses an insulating material bending machine for transformer production. When in use, the insulating material needs to be manually placed in the processing position according to the size requirements, and the bending is achieved by rotating the movable turn plate. At present, similar human-machine collaboration methods are used at home and abroad to produce soft angle rings. Soft angle rings still use the traditional processing method of manually operating mechanical equipment to corrugate and bend the cardboard. Manual processing of soft angle rings has low production efficiency. For soft angle rings with smaller sizes, manual corrugation and bending pose safety hazards. The processed soft angle rings have poor precision and large manufacturing tolerances. Once the quality of the soft angle ring fails to meet the design requirements, the purpose of protecting the wire coil cannot be achieved, which can easily cause creepage between wires, insulation breakdown, and short circuit faults.

DETAILED DESCRIPTION

[0016] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, but not all of the embodiments. Example 1

[0017] like Figure 1-16 As shown, the fully automatic processing equipment for soft corner rings includes a storage rack 6, a corrugating, bending, and unloading rack 7, and a finished product rack, arranged in sequence from front to back (front and back here are based on the direction of cardboard movement). The bottoms of the storage rack 6, corrugating, bending, and unloading rack 7, and finished product rack are equipped with height-adjustable feet. The flat structure at the bottom of the feet is placed on the workshop floor. The installation of the adjustable feet facilitates the 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 retractable cabinet doors installed around it. The space enclosed by the doors serves as an electrical cabinet, ensuring the safe installation and use of electrical equipment.

[0018] The top of the storage rack 6 is a flat plate structure, with a loading mechanism 1 and several storage mechanisms 5 fixedly mounted above the storage rack 6. The storage mechanism 5 includes a pair of parallel side panels arranged in the longitudinal direction and a blocking plate located at the rear end of the storage mechanism 5 in the width direction. The front end of the storage mechanism 5 is an open structure, and the spacing between the pair of side panels can be adjusted to accommodate cardboards of different widths. The loading mechanism 1 includes a loading robot, a loading conveyor belt 11, and a loading motor 12. The loading conveyor belt 11 is located to the side of the storage mechanism 5. The length of the loading conveyor belt 11 is consistent with the length of the storage mechanism 5 and is arranged parallel to it. The control mechanism 4 controls the operation of the loading conveyor belt 11 by controlling the loading 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 on the loading conveyor belt 11. The loading robot includes a loading support rod 15, a loading robot bracket 18, a mounting rod 19 and an electric suction cup 20. The three-dimensional structure of the 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 part of the loading robot bracket 18. The three-dimensional movement of the loading support rod 15 is realized by controlling the robot motor through the control mechanism 4. The top ends of several mounting rods 19 are evenly fixed on the loading support rod 15. The electric suction cup 20 is fixedly installed on 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 the cavity formed by a pair of side plates and a sealing plate at the rear end of the storage mechanism 5 at one time. The feeding mechanism 1 is controlled to operate automatically by the control mechanism 4, so that uninterrupted and continuous feeding can be achieved without manual intervention.

[0019] The top of the corrugating, bending, and unloading frame 7 is a flat plate structure. The corrugating mechanism 9, bending mechanism 2, and unloading mechanism 3 are fixedly mounted on the corrugating, bending, and unloading frame 7 in order from front to back. The control mechanism 4 is fixedly mounted on the unloading mechanism 3 via an L-shaped mounting bracket. The corrugating mechanism 9 is an existing product, and the corrugating rollers of the corrugating mechanism 9 are made of stainless steel or non-metallic insulating materials. The bending mechanism 2 includes a box shell, and the interior space of the box shell is equipped with a bending roller assembly mechanism. The bending roller assembly mechanism includes several sets of matching bending roller assemblies and clamping roller assemblies. The box shell ensures the safe operation of the bending roller assembly and clamping roller assembly. A cardboard feed port is provided at one end of the box shell near the corrugating mechanism 9, and a soft angle ring discharge port is provided at one end of the box shell near the discharge mechanism 3. A limiting mechanism 21 is installed at the front end of the cardboard feed port, and an overpressure rubber roller 10 is installed at the rear end of the soft angle ring discharge port, which is tilted upward at a certain angle. The bottom height of the overpressure rubber roller 10 is less than the height of the right-angle straight plate of the soft angle ring. If the cardboard is only bent to 90 degrees for discharge, the cardboard will rebound at a certain angle after discharge. Therefore, an overpressure rubber roller 10 is provided at the discharge port. The overpressure rubber roller 10 presses the soft angle ring to an angle smaller than 90 degrees, so that the soft angle ring will maintain a 90-degree angle after rebounding, and the rebound angle of the cardboard is offset by excessive bending.

[0020] The limiting mechanism 21 includes an upper limiting plate 22 and a lower limiting plate 23, which are arranged parallel to each other. The upper limiting plate 22 and the lower limiting plate 23 are fixedly mounted on the outer shell of the box. The spacing between the upper limiting plate 22 and the lower limiting plate 23 can be flexibly adjusted to accommodate different cardboard thicknesses. The lower limiting plate 23 has adjustment slots at both ends, the length of which aligns with the width of the cardboard. Mounting seats 24 are fixedly mounted on the outer ends of the adjustment slots. Adjustment screws 25 extend through the mounting seats 24 and are threadedly connected to the mounting seats 24. A pair of limiting bars 26 are fixed to the adjacent ends of the adjusting screws 25. The front ends of the limiting bars 26 are bent outward to facilitate the entry of the cardboard into the bending mechanism 2. The spacing between the limiting bars 26 can be flexibly adjusted by the adjusting screws 25, allowing the limiting mechanism 21 to accommodate cardboards of varying widths. The limiting mechanism 21 can accommodate different cardboard sizes, ensuring balanced cardboard feeding into the bending mechanism 2. Furthermore, the bending position of the cardboard can be flexibly adjusted by the limiting mechanism 21, enabling the processing of soft corner rings with different process requirements.

[0021] The bending mechanism 2 includes a bending roller group, a clamping roller group and a bending clamping motor 27 fixedly mounted on the corrugating, bending and unloading frame 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 group through a clamping chain 36 to drive the clamping roller group to rotate. The bending shaft 35 is connected to the bending roller group through a bending chain 37 to drive the bending roller group to rotate. The bending roller group includes a bending roller group 1 28, a bending roller group 29 and a bending roller group 30 arranged in sequence from front to back, and the clamping roller group includes a clamping roller group 1 31, a clamping roller group 2 32 and a clamping roller group 3 33 arranged in sequence from front to back. The clamping roller group 1 31, the clamping roller group 2 32 and the clamping roller group 3 33 are respectively located in front of the bending roller group 1 28, the bending roller group 2 29 and the bending roller group 3 30, and the cardboard passes through the clamping roller group 1 31, the bending roller group 1 28, the clamping roller group 2 32, the bending roller group 2 29, the clamping roller group 3 33 and the bending roller group 3 30 in sequence.

[0022] The clamping roller group 1 31 includes a pair of parallel clamping rollers 1 of the same length. The clamping roller group 2 32 and the clamping roller group 3 33 respectively include a pair of parallel clamping rollers 2 and 3 of different lengths. The length of the upper clamping roller 2 of the clamping roller group 2 32 is less than the length of the lower clamping roller 2. The length of the upper clamping roller 3 of the clamping roller group 3 33 is less than the length of the lower clamping roller 3. The bending roller group 1 28 and the bending roller group 2 29 respectively include a pair of relatively parallel frustum-shaped bending rollers 1 and 2. The upper bending roller 1 of the bending roller group 1 28 and the lower bending roller 1 have inclined surfaces adjacent to and overlap with each other. After the bent section of the cardboard passes through the inclined gap between the upper bending roller 1 and the lower bending roller 1, it is bent to form a bending structure with an angle of less than or equal to 30 degrees. The upper bending roller 2 of the bending roller group 29 and the lower bending roller 2 have inclined surfaces adjacent to and overlap with each other. After the bent section of the cardboard passes through the inclined gap between the upper bending roller second and the lower bending roller second, it is bent to form a bending structure of less than or equal to 60°. The bending roller group three 30 includes a pair of relatively parallel disc-structured bending rollers three. The lower end of the upper bending roller three of the bending roller group three 30 is adjacent to and overlaps with the upper end of the lower bending roller three. After the bent section of the cardboard passes through the gap between the upper bending roller three and the lower bending roller three, it is bent to form a 90° bending structure.

[0023] The unloading mechanism 3 includes a unloading motor 13 and a unloading conveyor belt 17. The unloading motor 13 and the unloading conveyor belt 17 are fixedly installed above the corrugating, bending and unloading rack 7. The length direction of the unloading conveyor belt 17 is consistent with the forward direction of the cardboard. The feeding end of the unloading conveyor belt 17 is located below the overpressure rubber roller 10, and the discharging end of the unloading 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 unloading conveyor belt 17 and the finished product storage bin 8. The unloading motor 13 and the unloading conveyor belt 17 are automatically operated by the control mechanism 4, so that the finished soft angle rings can be continuously unloaded and stacked in the finished product storage bin 8 without manual intervention.

[0024] A pair of finished product storage bin rails 16 arranged in parallel at a certain distance are fixedly installed on the upper surface of the finished product material rack. The finished product storage bin 8 is a rectangular box with a closed bottom and an open top. The upper surface of the bottom of the finished product storage bin 8 is processed with several positive V-shaped or inverted V-shaped structures that match the soft angle rings, so that the soft angle rings can be firmly 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 rails 16. The length direction of the finished product storage bin rails 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 angle ring. The finished product storage motor 14 is fixedly installed on the side of the finished product material rack, and 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 the finished soft angle rings are stacked in a row, the finished product storage motor 14 is automatically controlled by the control mechanism 4 to realize the horizontal movement of the finished product storage bin 8 along the width direction, so that the idle storage position in the finished product storage bin 8 is automatically in place, realizing the uninterrupted continuous reception and storage of finished soft angle rings without manual intervention.

[0025] Control mechanism 4 can use Siemens or equivalent series control equipment, including: PLC controller, touch screen, intermediate relay, small circuit breaker and 24V DC power supply, etc. In order to facilitate future equipment expansion, the PLC controller reserves 10% of I / O points. Example 2

[0026] The fully automatic processing method for soft angle rings is applied to the fully automatic processing equipment for soft angle rings described in Example 1, and includes the following steps: Step 1: Manually sort out the long strips of cardboard raw materials for making soft corner rings and stack them in the storage mechanism 5. The maximum height of the cardboard stack can reach 300 mm. Two or more rows of cardboard can be stacked in the storage mechanism 5, and a total of ≥1,000 pieces can be discharged at one time. Compared with the traditional loading method, the loading efficiency can be improved.

[0027] Furthermore, a material shortage alarm mechanism is provided at the material storage mechanism 5, and the material shortage alarm mechanism is electrically connected to the control mechanism 4, for example, a photoelectric sensor or a camera is used in conjunction with a material shortage sound and light alarm. When the material shortage alarm mechanism detects that the cardboard raw material in the material storage mechanism 5 is used up, the material shortage sound and light alarm is used to remind the staff to add cardboard raw materials.

[0028] Step 2: Manually adjust the limit mechanism 21 by adjusting the position of a pair of limit bars 26 so that the bending position of the cardboard meets the process requirements and ensures that the bending position deviation of the cardboard is less than ±1mm; adjust the position and tilt angle of the overpressure rubber roller 10 according to the process requirements of the soft angle ring.

[0029] Step 3: The control mechanism 4 controls the action of the feeding robot of the feeding mechanism 1. The electric suction cup 20 automatically grabs the cardboard from the storage mechanism 5, moves it into position, and automatically places the cardboard on the feeding conveyor belt 11. The control mechanism 4 controls the action of the feeding motor 12. The feeding motor 12 drives the feeding conveyor belt 11 to operate and feed the cardboard into the corrugating mechanism 9.

[0030] Step 4: The control mechanism 4 controls the corrugating mechanism 9 to automatically corrugate the cardboard, and then conveys the corrugated cardboard to the limiting mechanism 21 . The limiting mechanism 21 limits and guides the corrugated cardboard and then conveys it into the bending mechanism 2 .

[0031] Step 5. The control mechanism 4 controls the bending and clamping motor 27 to start, and the bending and clamping motor 27 drives the clamping roller group to clamp the corrugated cardboard. The bending and clamping motor 27 drives the bending roller group to bend the corrugated cardboard. The bending angle of each subsequent group of bending roller groups on the corrugated cardboard is greater than that of the previous group, until the last group of bending roller groups bends the bending section of the corrugated cardboard to form a 90° bending structure, and the corrugated cardboard is processed into a finished soft angle ring; after the soft angle ring is output from the soft angle ring outlet, it is excessively bent by the over-pressure rubber roller 10 to offset the rebound angle of the cardboard.

[0032] Step 6: The soft angle ring enters the unloading mechanism 3 from the soft angle ring outlet, the control mechanism 4 controls the unloading motor 13 to operate, and the unloading motor 13 drives the unloading conveyor belt 17 to transport the soft angle ring to the soft angle ring storage mechanism.

[0033] Step 7, the control mechanism 4 controls the finished product storage bin 8 to move to the storage position, and the finished soft angle rings are automatically stacked neatly in the finished product storage bin 8; when the soft angle rings in a row are stacked to the set height, the control mechanism 4 controls the finished product storage bin 8 to move, so that the vacant storage position in the finished product storage bin 8 is automatically in place.

[0034] Furthermore, a full-fill sound and light alarm is set at the finished product storage bin 8. The number of full-filled soft angle rings in the finished product storage bin 8 is preset in the control mechanism 4. When the number of soft angle rings in the finished product storage bin 8 reaches the input full number, the control mechanism 4 controls the full-fill sound and light alarm to remind the operator to pack the finished soft angle rings. The packed soft angle rings are transported by a transfer trolley made of aluminum profiles.

[0035] Furthermore, the control mechanism 4 is equipped with a data acquisition system, whose data interface is seamlessly connected to the company's MES system to achieve real-time data exchange. The control mechanism 4 is equipped with a touch screen, through which various information parameters of the cardboard are input to achieve data exchange.

[0036] When using the fully automatic processing equipment for soft angle rings described in the embodiment of the present invention, it is only necessary to manually comb the cardboard raw materials for making soft angle rings and stack them in the storage mechanism 5, and then set the moving rhythm and moving distance of the finished product storage bin 8 through the control mechanism 4. After the fully automatic processing equipment is powered on, the cardboard loading, cardboard corrugating, cardboard bending, finished soft angle ring unloading, and finished soft angle rings are automatically stacked and stored in the finished product storage bin 8. Finally, the processed soft angle rings are manually packaged and sorted, and the finished soft angle rings are transported by the AGV transfer cart. The remaining production links do not require manual operation, which greatly saves personnel costs and reduces safety hazards.

[0037] In the embodiments of the present invention, technical features not described in detail are all existing technologies or conventional technical means and will not be described in detail here.

[0038] Finally, it should be noted that the above embodiments are only specific implementation methods of the present invention, which are used to illustrate the technical solutions of the present invention, rather than to limit them, and the protection scope of the present invention is not limited thereto. Those skilled in the art should understand that any person skilled in the art can modify or easily think of changes to the technical solutions described in the above embodiments within the technical scope disclosed by the present invention, or make equivalent replacements for some of the technical features therein; and these modifications, changes or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention, and should all be included in the protection scope of the present invention.
