[0002] A transformer is a device that uses the principle of electromagnetic induction to change alternating current voltage. Transformer impregnation is a crucial step in the production process, primarily serving to fix, insulate, and prevent short circuits between layers. Currently, the production process involves: 1. Manually placing trays containing products into the impregnation machine for impregnation, then removing the products one by one and transferring them to drying trays. This repeated handling and turnover reduces production efficiency; 2. Most impregnation solution dilution machines contain benzene and xylene, which pose significant health risks with prolonged manual exposure. Utility Model Content

The feeding mechanism 2 includes a feeding track 201 and a feeding sensor 202, with the feeding sensor 202 mounted at the rear end of the feeding track 201. The impregnation mechanism 3 includes an immersion tank 301, a sealing tank cover 302, a movable sub-tank 303, and a sub-tank lifting system 304. The immersion tank 301 contains an impregnation solution, and a partition 305 is provided in the middle of the immersion tank 301, separating an independent impregnation tank. The movable sub-tank 303 is located inside the independent impregnation tank, and the sub-tank lifting system 304 is located below the immersion tank 301. The sub-tank lifting system 304 passes through the bottom of the immersion tank 301 and connects to the side of the movable sub-tank 303. The sealing tank cover 302 moves horizontally.

[0027] The carrier tray is placed into the feed track 201 until it is detected by the feed sensor 202. The moving structure grabs the carrier tray and places it into the movable sub-cylinder 303 inside the soaking tank 301. The sealing cylinder cover 302 moves above the soaking tank 301 and then moves down to cover the soaking tank 301. The impregnation solution performs vacuum impregnation on the transformer inside the carrier tray. The impregnation solution includes varnish and other substances. The partition 305 allows different impregnation solutions to be used in different areas. Then the sealing cylinder cover 302 is opened, and the sub-cylinder lifting system 304 controls the movable sub-cylinder 303 to rise out of the impregnation solution, allowing the moving structure to lift the carrier tray away.

[0028] Feeding shafts 203 are installed at both ends of the feeding track 201. Feeding sprockets 204 are installed at the ends of the feeding shafts 203. A feeding chain 205 is connected between the front and rear feeding sprockets 204. A feeding motor 206 is installed below the feeding track 201. The drive end of the feeding motor 206 is connected to the feeding chain 205 through the feeding sprockets 204. During the feeding process, the feeding motor 206 drives the feeding sprockets 204 to rotate. With the assistance of the feeding shafts 203, the feeding chain 205 transports the carrier disc backward.

[0029] A cylinder head moving strip 306 is provided on the first bracket 1. A cylinder head moving cylinder 307 is fixed on the cylinder head moving strip 306. The driving end of the cylinder head moving cylinder 307 is connected to a cylinder head moving plate 308. A cylinder head lifting cylinder 309 is installed on the cylinder head moving plate 308. The cylinder head lifting cylinder 309 controls the lifting and lowering of the sealed cylinder head 302. A cylinder head slide rail 310 is fixed on the cylinder head moving strip 306. A cylinder head slider 311 is fixed on the cylinder head moving plate 308. The cylinder head slider 311 slides along the cylinder head slide rail 310 in the front-back direction. Cylinder head guide shafts 312 are provided at both ends of 308 along the vertical direction. Cylinder head linear bearings 313 are fixed on the sealing cylinder head 302. The cylinder head guide shafts 312 pass through the cylinder head linear bearings 313. The cylinder head moving cylinder 307 controls the sealing cylinder head 302 to move horizontally along the cylinder head slide rail 310. The cylinder head lifting cylinder 309 controls the lifting of the sealing cylinder head 302 to achieve the function of opening or sealing the soaking tank 301. The cylinder head guide shafts 312 can stably seal the soaking tank 301 and prevent it from shifting.

[0030] The sub-cylinder lifting system 304 is equipped with a sub-cylinder lifting motor 314. The drive end of the sub-cylinder lifting motor 314 is connected to the sub-cylinder lifting screw 315 via a synchronous pulley and synchronous belt. The upper flange of the sub-cylinder lifting screw 315 is connected to the sub-cylinder lifting base plate 316. The end of the sub-cylinder lifting base plate 316 is fixed with a sub-cylinder lifting guide rod 317. The soaking tank 301 is fixed with a sub-cylinder lifting guide cylinder 318. The side of the movable sub-cylinder 303 is fixed with a sub-cylinder connecting plate 319. The sub-cylinder lifting guide rod 317 passes through the sub-cylinder lifting guide cylinder 318 and is fixedly connected to the sub-cylinder connecting plate 319. After soaking, the sub-cylinder lifting motor 314 controls the rotation of the sub-cylinder lifting screw 315 to raise the sub-cylinder lifting base plate 316. The sub-cylinder lifting guide rods 317 on both sides pull the movable sub-cylinder 303 to lift the carrier plate away from the surface of the soaking liquid, so that the carrier plate can be grabbed and removed by the moving structure.

[0031] The movable sub-cylinder 303 has a carrier support frame 320 fixed inside. The first bracket 1 is equipped with an impregnation liquid storage tank 321. The impregnation liquid storage tank 321 is provided with a filling port 322, which can replenish the impregnation liquid from the impregnation liquid storage tank 321 into the immersion tank 301.
