[0003] In the Chinese patent application number CN202411252485.3, entitled “An Electronic Component Inspection Equipment”, the patent discloses that after preliminary inspection of electronic components, one inspection camera A and two inspection cameras B are used to grasp the electronic components after preliminary inspection through a clamping mechanism, and a reduction motor and a linkage mechanism are used to drive the clamping mechanism to flip, thereby realizing automatic flipping of the electronic components without manual intervention. This reduces the intensity of manual labor and achieves the effect of saving time and effort, while also improving the continuity of electronic component inspection and effectively improving the inspection efficiency of electronic components. Another inspection camera A is used to perform secondary inspection of the flipped electronic components, thereby realizing all-round defect detection of electronic components. When testing a transformer, this patent can only test smaller electrical components by flipping the electrical components, and cannot test larger transformers.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. A detection and correction component is provided. The electric rail drives the assembly frame to move to the top of the transformer. The electric push rod is moved horizontally to drive the assembly frame to move. The socket hole directly below the fixed seat is aligned with the wiring terminal in the middle of the transformer. The servo motor drives the socket hole directly below the moving block to align with the other two wiring terminals. When the distance between the wiring terminals of the detection transformer is different, the device can still be applied. The device has a wide range of applications. After the three terminals are aligned, the cleaning sponge is driven down by the lifting electric push rod, the socket hole is sleeved on the outside of the terminal, and the cleaning motor drives the cleaning sponge to rotate to clean the terminal. After cleaning, the air nozzle is driven to align with the terminal by the lifting electric push rod, and the air pump is used to transport air to the inside of the heating tube. The air is heated by the heating wire and then ejected through the air nozzle. At the same time, the cleaning motor drives the air nozzle to rotate to clean and dry the transformer terminals. When the detection head contacts the transformer terminals later, inaccurate transformer detection results due to stains on the terminal surface are avoided, the detection accuracy of the transformer is improved, and the detection effect is better. After the terminals are cleaned and dried, the transformer is immediately inspected to avoid secondary contamination of the terminals, thereby improving the detection effect. There is no need to manually connect and fix the detection head to the terminals for detection, which reduces labor intensity. The inside of the moisturizing ring box is filled with anhydrous ethanol. Every once in a while, anhydrous ethanol can be dripped out from the quantitative dropper and soaked into the cleaning sponge to keep the cleaning sponge moist, so that the device has continuous cleaning ability. When the cleaning sponge needs to be replaced, rotate the connecting screw to remove the old cleaning sponge and install the new cleaning sponge. It is convenient and quick.

[0016] 2. An irradiation detection matching component is provided. The lifting screw is driven by the lifting motor to rotate, so that the infrared thermal imager and the industrial perspective instrument can move up and down. When inspecting the transformer, the infrared thermal imager scans and locates the hot spots of the transformer, which is convenient for locking the short-circuit position of the transformer silicon steel sheet. The industrial perspective instrument analyzes the changes after the X-ray penetrates the transformer winding, thereby obtaining the shape of the transformer winding and judging whether the transformer winding is deformed. In the subsequent transformer maintenance, the maintenance worker can quickly find the loss point, which improves the maintenance speed of the transformer; Under the connection drive action of the linkage belt, the lifting motor drives the driven pulley and the cam column to rotate, and the rotation of the cam column drives the toggle lever to rotate. Under the elastic reset action of the swing spring, when the mounting plate moves up and down, the toggle lever is in real time fitted with the outer side of the cam column to realize the back and forth swing of the swing frame. The infrared thermal imager and the industrial perspective instrument also swing back and forth during the process of moving up and down, which makes the infrared thermal imager and the industrial perspective instrument have a wider illumination range, avoids the generation of blind angles of illumination, and improves the detection effect of the device.

[0017] To sum up, when the detection and correction component detects the loss of transformer components, the irradiation detection coordination component simultaneously locates the loss components. The two components work together, and the device can quickly detect and locate the loss components of the transformer. Cooperating with the mobile vehicle to move the transformer, it is convenient for manufacturers to repair the transformer, shortens the repair time, and improves the manufacturer's efficiency.

The quantitative dropper 218 is located on the top of the cleaning sponge 215, and the moisturizing ring box 217 is filled with anhydrous ethanol. At regular intervals, anhydrous ethanol can be quantitatively dripped from the quantitative dropper 218 and immersed into the cleaning sponge 215 to keep the cleaning sponge 215 moist. When the cleaning sponge 215 needs to be replaced, the old cleaning sponge 215 is removed by rotating the connecting screw 214, and a new cleaning sponge 215 is installed. A sealing plug 219 is connected to one side of the top of the moisturizing ring box 217. The sealing plug 219 can seal the moisturizing ring box 217. When the anhydrous ethanol in the moisturizing ring box 217 is consumed, the sealing plug 219 is removed to replenish the anhydrous ethanol, which is convenient and quick. After cleaning is completed, the lifting electric push rod 201 drives the cleaning sponge 215 to separate from the terminal, so that the nozzle head 223 is aligned with the terminal. Then, the air pump 228 transports air to the inside of the heating tube 225. The air is heated by the electric heating wire 227 and flows through the gas distribution hose 226 and the drying ring box 220 into the inside of the nozzle tube 222, and finally ejected from the nozzle head 223. At the same time, the cleaning motor 212 drives the threaded cylinder 213 to rotate. Under the connection action of the linkage rod 224, the nozzle tube 222, the nozzle head 223 and the rotating ring 221 rotate. The hot air ejected from the nozzle head 223 dries the cleaned transformer terminal, thereby cleaning and drying the transformer terminal. When the subsequent detection head 211 contacts the transformer terminal, it avoids inaccurate transformer detection results due to stains on the terminal surface, thereby improving the detection accuracy of the transformer and achieving better detection effect. Subsequently, the lifting electric push rod 201 drives the air jet head 223 to separate from the terminal block, and then the translation electric push rod 203 drives the assembly frame 204 to move, so that the detection head 211 is aligned with the terminal block, and then the docking electric push rod 210 drives the detection head 211 to descend, so that the detection head 211 is docked with the terminal block, and the detection head 211 is connected to the external transformer capacity tester. The transformer capacity tester can test the specific parameters of the transformer, so as to judge the performance loss of the transformer components. After the terminal block is cleaned and dried, the transformer is immediately tested to avoid secondary contamination of the terminal block, improve the detection effect, and do not need to manually connect and fix the detection head 211 to the terminal block for testing, which reduces the labor intensity and is convenient and quick. During transformer inspection, the infrared thermal imager 310 and the industrial perspective camera 311 also operate simultaneously. The lifting motor 306 drives the lifting screw 305 to rotate, and the lifting block 304 moves up and down inside the lifting rail 303, thereby driving the infrared thermal imager 310 and the industrial perspective camera 311 to move up and down. When the transformer is connected to the power supply for inspection, the ground current suddenly increases with an abnormal local temperature rise. The infrared thermal imager 310 scans and locates the hot spots of the transformer, facilitating the identification of the short-circuited position of the transformer silicon steel sheets. The industrial perspective camera 311 is an X-ray perspective camera. By analyzing the changes after the X-rays penetrate the transformer windings, the shape of the transformer windings can be determined to determine whether the transformer windings are deformed. During subsequent transformer maintenance, maintenance workers can quickly find the loss points, thereby improving the maintenance speed of the transformer. When the lifting screw 305 rotates, it also drives the driving pulley 315 to rotate. Under the connection driving action of the linkage belt 318, the lifting motor 306 drives the driven pulley 317 and the cam column 316 to rotate. The rotation of the cam column 316 drives the toggle rod 314 to rotate, and the toggle rod 314 drives the swing spring 313 to rotate. Under the elastic reset action of the swing spring 313, when the mounting plate 307 moves up and down, the toggle rod 314 is in real time in contact with the outer side of the cam column 316, realizing the back and forth swing of the swing frame 309, thereby driving the infrared thermal imager 310 and the industrial perspective camera 311 to swing back and forth. The infrared thermal imager 310 and the industrial perspective camera 311 also swing back and forth during the process of moving up and down, so that the infrared thermal imager 310 and the industrial perspective camera 311 have a wider illumination range, avoid the generation of blind angles in illumination, and have a better detection effect of the device.
