Description
Technical Field
[0001] This invention relates to the field of transformer core processing technology, specifically to an automated transformer core processing tool and a transformer core thereof. Background Technology
[0002] Transformer core is the main magnetic circuit part of a transformer. It is usually made of hot-rolled or cold-rolled silicon steel sheets with high silicon content and coated with insulating varnish. The core and the coils wound on it form a complete electromagnetic induction system. The power transmission capacity of a power transformer depends on the material and cross-sectional area of the core. In Chinese patent CN119296945B, entitled "A Transformer Core Lamination Device", the patent uses two sets of suction cups. When one set of suction cups picks up the core, the other set of suction cups can insert the core between two adjacent sets of insulating materials, which helps to improve the efficiency of core lamination. Moreover, it eliminates the need for manual lamination of the core, reduces contact between workers and the core, and thus avoids the core from scratching workers. This patent and existing technologies often use robotic arms to automatically stack sheared silicon steel sheets. However, during the stacking process, dust and other impurities often adhere to the surface of the silicon steel sheets due to precision requirements. These impurities can scratch the insulating protective layer on the surface of the silicon steel sheets due to pressure during stacking, resulting in a reduction in the forming quality of the transformer core. Furthermore, after shearing, some mechanical stress remains inside the silicon steel sheets. After stacking, the residual mechanical stress can easily form localized stress concentrations, affecting the stacking waviness and reducing the forming quality of the transformer core.

[0013] A transformer core, manufactured according to the above technical solution, wherein the core body is placed on top of the support frame and support base, the core body includes a clamp and a silicon steel sheet, two clamps are provided, the two clamps are respectively located at the top and bottom of the silicon steel sheet, the top surface of the support frame and support base contacts the bottom surface of the clamp located at the bottom, positioning holes are opened on the surfaces of the clamp and the silicon steel sheet, and the top end of the positioning rod passes through the positioning hole.
[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. A stacking and fixing assembly is provided. The bottom clamp is placed on the support base and the top of the support frame. The external robotic arm adsorbs the silicon steel sheets and places them on the top of the bottom clamp. The positioning rod positions and fixes the placed silicon steel sheets. During the stacking of silicon steel sheets, ionized air delivered by the plasma fan enters the air-driven box. The ionized air drives the fan and the air jet box to rotate. The ionized air is ejected from the nozzles, blowing away dust and other impurities on the top surface of the silicon steel sheets. In conjunction with the lifting cylinder, the air jet box rises with the thickness of the silicon steel sheets. During the stacking process of silicon steel sheets, it is possible to prevent debris from damaging the insulating protective layer on the surface of the silicon steel sheets. At the same time, the ejected ionized air can eliminate static electricity on the silicon steel sheets, reduce the adsorption capacity of the silicon steel sheets for dust, and improve the stacking quality of the iron core. Meanwhile, the bidirectional motor drives the moving screw to rotate, changing the position of the air jet box in real time, expanding the effective range of the air jet box, avoiding the generation of dead corners, and further ensuring the stacking quality of the iron core. During the stacking of silicon steel sheets, the excitation motor runs, and the mechanical stress of the stacked sheets is eliminated under the action of vibration transmission. After all the silicon steel sheets are stacked, the clamping plate is passed through the middle of the two clamping sleeves. The lifting cylinder has two functions. The clamping plate is driven to descend through the lifting cylinder. Under the action of pressure, the stacked silicon steel sheets are more compact, reducing the air gap between the stacked sheets, reducing magnetic resistance, and increasing magnetic permeability. Moreover, the clamping helps to eliminate local stress concentration between the stacked sheets, reduce the waviness of the iron core, and fully improve the forming quality of the iron core. Multiple negative pressure holes are evenly spaced on both sides of the square tube. When the vacuum cleaner is vacuuming, the pressure inside the square tube decreases. Under the action of pressure difference, outside air enters the inside of the square tube through the negative pressure holes, and the dust blown away enters the inside of the square tube and finally enters the vacuum cleaner, thus avoiding the generation of dust and protecting the on-site working environment. Both the support base and the connecting base are modularly installed. During lamination, the positions of the fixed base and the auxiliary support base can be changed by controlling the adjusting motor and the movable motor. The support base can support the fixture, and the positioning rod can pass through the positioning holes on the surface of the fixture and the silicon steel sheet. The equipment can be flexibly adjusted according to the size of the iron core and has a wide range of applications.
[0015] 2. Equipped with a positioning dust removal component, the silicon steel sheet is moved to the center of the positioning platform by an electric roller. Then, the connecting rod seat is moved by the centering cylinder. Under the driving action of the linkage rod and the connecting seat, the centering rod fixes the silicon steel sheet in the center, ensuring the initial position of the silicon steel sheet. This ensures the stacking accuracy when the robotic arm stacks the sheets. When the silicon steel sheet moves with the electric roller, the vacuum cleaner runs. Some air enters the sealed air box at one end of the electric roller through the air inlet pipe, and then enters the electric roller through the connecting hole. The other part of the air enters the electric roller through the dust suction hole. The airflow from the two different directions forms turbulence. The turbulence impacts the vibrating sheet, causing it to vibrate. Under the action of vibration transmission, the electric roller and the silicon steel sheet vibrate. Vibration can reduce the mechanical stress of the silicon steel sheet caused by shearing, thus reducing stress accumulation during subsequent stacking. When the silicon steel sheets vibrate, dust and other debris adsorbed on the bottom surface of the silicon steel sheets will fall off. During subsequent lamination, this prevents the debris from damaging the insulating protective layer on the surface of the silicon steel sheets, thus improving the lamination quality of the transformer core. The fallen dust can enter the electric drum through the dust suction hole and finally enter the vacuum cleaner, preventing dust generation and protecting the on-site environment. Furthermore, when air flows inside the electric drum, the air pressure inside the electric drum is lower than the air pressure outside. Under the action of the pressure difference, the silicon steel sheets can move stably on the top of the electric drum, preventing slippage and ensuring positioning accuracy. Furthermore, the electric roller and the connecting cylinder are connected by a connecting flange, a mating flange, a connecting rod, and a connecting spring. By pulling the linkage ring, the connecting rod can be moved out of the connecting flange, allowing the electric roller to be quickly disassembled. When the inside of the electric roller is dirty, it is easy to clean the electric roller, which is convenient and quick. In summary, the positioning dust removal component utilizes turbulent impact vibration plates to drive the electric drum and silicon steel sheets to vibrate, thereby removing impurities from the bottom surface of the silicon steel sheets. The stacking and fixing component uses ion wind to remove impurities from the top surface of the silicon steel sheets. The two components work together to clean the silicon steel sheets during the stacking process, eliminating the need for additional cleaning devices. This ensures the forming quality of the transformer core while also improving processing efficiency. Attached Figure Description

The output end of the centering cylinder 321 is connected to... The device includes a connecting rod seat 322, a tap seat 320 connected to the bottom center of a centering plate 318, and a linkage rod 323 rotatably connected between the tap seat 320 and the connecting rod seat 322. The input terminals of the adjusting motor 206, lifting cylinder 210, bidirectional motor 219, plasma fan 222, movable motor 226, vibration motor 236, electric roller 302, vacuum cleaner 315, and centering cylinder 321 are electrically connected to the output terminal of an external controller. The input terminal of the controller is electrically connected to the output terminal of an external power supply. The controller can uniformly control various electrical components, facilitating automated control of the equipment. A transformer core is processed according to the aforementioned automated transformer core processing tool. A core body 4 is placed on top of a support frame 235 and a support base 237. The core body 4 includes a clamp 401 and a silicon steel sheet 402. Two clamps 401 are provided, located at the top and bottom of the silicon steel sheet 402 respectively. The top surface of the support frame 235 and the support base 237 contacts the bottom surface of the clamp 401 located at the bottom. Positioning holes 403 are opened on the surfaces of both the clamp 401 and the silicon steel sheet 402. The top end of the positioning rod 232 passes through the positioning hole 403.
[0020] The working principle and usage process of this invention: Before processing, the position of the connecting seat 230 at the top of the fixed seat 207 and the auxiliary support seat 227 is adjusted according to the size of the iron core to be processed, and the position of the support seat 237 at the top of the fixed seat 207 is adjusted. By controlling the adjusting motor 206 to drive the adjusting screw 205 to rotate, and then controlling the movable motor 226 to drive the movable screw 225, the position of the fixed seat 207 and the auxiliary support seat 227 is changed, so that the support seat 237 can support the clamp 401, and the positioning rod 232 can pass through the positioning hole 403 on the surface of the clamp 401 and the silicon steel sheet 402. The equipment can be flexibly adjusted according to the size of the iron core, and the equipment has a wide range of applications. After the position of the positioning rod 232 and the support seat 237 is adjusted, the bottom clamp 401 is placed on top of the support seat 237 and the support frame 235. Next, the electric roller 302 operates, and the external conveyor belt conveys silicon steel sheets 402 one by one to the top of the electric roller 302. When the silicon steel sheets 402 are conveyed to the top of the electric roller 302, the electric roller 302 drives the silicon steel sheets 402 to move to the middle of the positioning platform 301. Then, the centering cylinder 321 drives the connecting rod seat 322 to move. Under the connection and drive of the linkage rod 323 and the tapping seat 320, the centering cylinder 321 drives the two centering plates 318 to move closer to each other synchronously along the lifting slide rod 317. The centering rod 319 fixes the silicon steel sheets 402 in the center. When the robotic arm adsorbs the silicon steel sheets 402 for transfer and stacking, the initial position of the silicon steel sheets 402 is ensured. When the robotic arm stacks the sheets, the stacking accuracy is ensured. When the silicon steel sheet 402 moves with the electric roller 302, the vacuum cleaner 315 operates. Part of the air enters the sealed air box 312 at one end of the electric roller 302 through the air inlet pipe 313, and then enters the electric roller 302 through the connecting hole 311. The other part of the air enters the electric roller 302 through the suction hole 303, and then enters the exhaust pipe 314 through the sealed air box 312 at the other end of the electric roller 302, finally entering the vacuum cleaner 315. The two airflows in different directions create turbulence. This turbulence impacts and vibrates the vibrating plate 304, causing it to vibrate. Under the influence of vibration transmission, this vibrates both the electric roller 302 and the silicon steel sheet 402. This vibration reduces the mechanical stress on the silicon steel sheet 402 caused by shearing. During subsequent lamination, stress accumulation is reduced. Simultaneously, when the silicon steel sheet 402 vibrates, dust and other debris adsorbed on its bottom surface will fall off, preventing damage to the insulating protective layer on the surface of the silicon steel sheet 402 during subsequent lamination. This improves the lamination quality of the transformer core. The fallen dust can enter the electric drum 302 through the dust extraction hole 303 and finally into the vacuum cleaner 315, preventing dust generation and protecting the on-site environment. Furthermore, when air flows inside the electric drum 302, the air pressure inside the electric drum 302 is lower than the external ambient air pressure. Under the action of this pressure difference, the silicon steel sheet 402 can move stably on the top of the electric drum 302, preventing slippage and ensuring positioning accuracy. Furthermore, the electric roller 302 and the connecting cylinder 306 are connected by the connecting flange 305, the mating flange 307, the connecting rod 308 and the connecting spring 310. By pulling the linkage ring 309, the connecting rod 308 can be moved out of the connecting flange 305, and the electric roller 302 can be quickly disassembled. When the inside of the electric roller 302 is dirty, it is easy to clean the electric roller 302, which is convenient, quick and easy, and facilitates subsequent maintenance. After the silicon steel sheet 402 is positioned on top of the electric roller 302, the external robotic arm adsorbs the silicon steel sheet 402 and places it on top of the clamp 401 at the bottom. The positioning rod 232 positions and fixes the placed silicon steel sheet 402. During the stacking of silicon steel sheets 402, the plasma fan 222 operates. The ionized air delivered by the plasma fan 222 enters the air-driven box 212 through the air delivery hose 223. Driven by the wind, the ionized air drives the fan 213, the linkage shaft 216, and the jet box 214 to rotate. Finally, the ionized air is ejected from the nozzle 215. The ionized air ejected from the rotating jet box 214 blows the top surface of the silicon steel sheet 402, removing dust and other impurities. During subsequent stacking, the rising... The lowering cylinder 210 drives the jet box 214 to rise along with the thickness of the silicon steel sheet 402. During the stacking process of the silicon steel sheet 402, it avoids debris from damaging the insulating protective layer on the surface of the silicon steel sheet 402, thus improving the stacking quality of the transformer core. At the same time, the sprayed ion wind can eliminate static electricity on the silicon steel sheet 402, reduce the adsorption capacity of the silicon steel sheet 402 for dust, and further improve the stacking quality of the core. When the ion wind blows, the bidirectional motor 219 drives the moving screw 220 to rotate, and the L-shaped frame 209 moves back and forth along the surface of the frame rod 208, thereby changing the position of the jet box 214 in real time, expanding the effective range of the jet box 214, avoiding the generation of blowing dead angles, and further ensuring the stacking quality of the core. Multiple negative pressure holes 238 are equally spaced on both sides of the square tube 202. A vacuum cleaner connector 239 is connected to the vacuum cleaner 315 using a hose. When the vacuum cleaner 315 is vacuuming, the pressure inside the square tube 202 decreases. Under the action of the pressure difference, outside air enters the square tube 202 through the negative pressure holes 238. The blown-off dust enters the square tube 202 and finally enters the vacuum cleaner 315, thus avoiding the generation of dust and protecting the on-site working environment. During the stacking of silicon steel sheets 402, the excitation motor 236 also operates. Under the action of vibration transmission, the mechanical stress of the stacked sheets is further eliminated, which helps to eliminate local stress concentration between the stacked sheets. After all the silicon steel sheets 402 are stacked, the top clamp 401 is placed on top of the stacked silicon steel sheets 402, and the pressure plate 218 is passed through the middle of the two pressure sleeves 217. The lifting cylinder 210 drives the pressure plate 218 to descend, and the pressure plate 218 applies downward pressure to the top clamp 401. Under the action of pressure, the stacked silicon steel sheets 402 can... The more compact silicon steel sheets 402 reduce the air gap between the stacked sheets, lower the magnetic resistance, and increase the magnetic permeability. The compaction also helps to eliminate local stress concentration between the stacked sheets, reduce the waviness of the iron core, and significantly improve the forming quality of the iron core. After compaction, use the disassembly handle 234 to remove each positioning rod 232 from the threaded tube 231 and remove the positioning rod 232 from the iron core. Then, fix the clamp 401 to the stacked silicon steel sheets 402. After fixing, use a lifting tool to remove them. During subsequent processing, the positioning rod 232 can be installed back in its original position. In the positioning dust removal component 3, the turbulent impact vibration plate 304 drives the electric roller 302 and silicon steel sheet 402 to vibrate, and the vibration removes the impurities on the bottom surface of the silicon steel sheet 402. In the stacking and fixing component 2, the ion wind blows to remove the impurities on the top surface of the silicon steel sheet 402. The two components work together to clean the silicon steel sheet 402 during the stacking process, without the need for additional cleaning equipment. This ensures the forming quality of the transformer core while also improving processing efficiency.
