Description

Technical Field

[0001] This utility model relates to the technical field of transformer manufacturing, and in particular to an automatic impregnation and baking production line. Background Technology

[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. Current impregnation and baking processes are single-stage operations, unable to be integrated with intermediate assembly equipment or final product testing equipment to form a fully automated production line. Each step requires manual handling and turnover, resulting in low production efficiency, excessive human intervention, and poor product quality consistency after impregnation and baking. Furthermore, most impregnation solvents contain harmful substances such as benzene and xylene. Prolonged exposure can easily lead to occupational diseases. Utility Model Content

[0049] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0050] like Figures 1 to 18 As shown in this embodiment, an automatic dip-coating and baking production line includes a first support 1 and a feeding mechanism 2 and a dip-coating mechanism 3 mounted on the first support 1; it also includes a second support 4 and a drip-drying mechanism 5, a cleaning and wiping mechanism 6, an air-drying mechanism 7, and a moving mechanism 8 mounted on the second support 4; it also includes a transport mechanism 9 that moves between the first support 1 and the second support 4; and it also includes a baking mechanism 10, a transfer mechanism 11, and a turnover vehicle 12.

[0051] The feeding mechanism 2 inputs the carrier tray 903 with a transformer. The handling mechanism 9 puts the carrier tray 903 into the impregnation mechanism 3 for immersion in the impregnation liquid, which includes varnish and other substances. Then, the handling mechanism 9 removes the carrier tray 903 from the impregnation mechanism 3, the dripping mechanism 5 drains the liquid, and transfers it to the cleaning and wiping mechanism 6 for wiping. Then, it is dried by air blowing in the air drying mechanism 7. The moving mechanism 8 moves the carrier tray 903 into the baking mechanism 10 for high-temperature baking. Finally, driven by the transfer mechanism 11, the carrier tray 903 is placed into the turnover frame 12 for storage.

[0052] The feeding mechanism 2 includes a feeding track 201 and a feeding sensor 202, with the feeding sensor 202 installed at the rear end of the feeding track 201; the impregnation mechanism 3 includes an impregnation tank 301, a sealing tank cover 302, a movable sub-tank 303, and a sub-tank lifting system 304. The impregnation tank 301 contains an impregnation solution, and a partition 305 is provided in the middle of the impregnation tank 301, which separates two independent impregnation tanks. The movable sub-tank 303 is located in the independent impregnation tank, and the sub-tank lifting system 304 is located below the impregnation tank 301. The sub-tank lifting system 304 passes through the bottom of the impregnation tank 301 and connects to the side of the movable sub-tank 303. The sealing tank cover 302 moves horizontally.

[0053] The carrier tray 903 is placed into the feed track 201 until it is sensed by the feed sensor 202. The moving structure then picks up the carrier tray 903 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 903. 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 903 away.

[0054] 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 rotation of the feeding sprockets 204. With the assistance of the feeding shafts 203, the feeding chain 205 transports the carrier disc 903 backward.

[0055] 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.

[0056] 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 903 away from the surface of the soaking liquid, so that the carrier plate 903 can be grasped and removed by the moving structure.

[0057] 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.

[0058] The drip-drying mechanism 5 includes a drip-drying frame 501, with a drip-drying mesh frame fixed inside the drip-drying frame 501, and a gap between the drip-drying mesh frame and the inner bottom of the drip-drying frame 501; the cleaning and wiping mechanism 6 includes a cleaning frame 601, a cleaning fluid storage tank, and a cleaning fluid circulation system, with a cleaning lifting system 602 installed below the cleaning frame 601, and a brush plate 603 installed inside the cleaning frame 601, the drive end of the cleaning lifting system 602 controlling the lifting and lowering of the cleaning frame 601; the air-drying mechanism 7 includes an air-drying frame 701, an air tank, an air knife, and a immersion liquid return pipe, with a blower installed below the air-drying frame 701, and several air-drying holes installed in the middle of the air-drying frame 701; the moving mechanism 8 includes a moving frame 801, with a push-in cylinder 802 fixed on the moving frame 801, the drive end of the push-in cylinder 802 connected to a push-in plate 803, and the rear end of the push-in plate 803 bent upward to form a push-in locking position 804.

[0059] After the transformer has been soaked in the impregnation solution, it is placed in the carrier tray 903 and then placed together with the carrier tray 903 into the dripping mesh frame of the dripping mechanism 5. The liquid impregnation solution drips down the dripping mesh frame onto the bottom of the dripping frame 501. Then the carrier tray 903 is placed into the cleaning frame 601. The cleaning lifting system 602 controls the cleaning frame 601 to rise, causing the brush plate 603 to contact the lower end of the carrier tray 903 and wipe the residual impregnation solution at the lower end of the carrier tray 903. Finally, the carrier tray 903 is placed into the blowing frame, and the blower blows air upwards, drying the carrier tray 903 through the air drying holes. After ensuring that there is no liquid impregnation solution, the carrier tray 903 is placed into the push plate 803 of the moving frame 801. The push cylinder 802 controls the push plate 803 to move backward. With the assistance of the push-in locking position 804, the carrier tray 903 smoothly enters the baking equipment.

[0060] An inclined water guide plate 502 is provided on the front side of the drip drying frame 501. The inclined water guide plate 502 is inclined downward towards the middle of the drip drying frame. After the impregnation liquid is soaked from the front, the impregnation liquid will drip down from the carrier plate 903. With the inclined water guide plate 502 present, the impregnation liquid will be collected back into the drip drying frame along the inclined water guide plate 502.

[0061] A cleaning lifting fixed plate 604 is fixed on the second bracket 4. The cleaning lifting system 602 is equipped with a cleaning lifting motor 605. The drive end of the cleaning lifting motor 605 is connected to a cleaning lifting screw 606 via a reducer. A cleaning lifting movable plate 607 is connected to the bottom of the cleaning frame 601. The upper flange of the cleaning lifting screw 606 is connected to the middle of the cleaning lifting movable plate 607. A cleaning guide rod 608 is fixed to the lower end of the cleaning lifting movable plate 607. A cleaning guide cylinder 609 is installed on the cleaning lifting fixed plate 604. The cleaning guide rod 608 passes through and slides on the cleaning guide cylinder 609. A cleaning movable cylinder 610 and a cleaning movable slider 611 are fixed on the cleaning lifting movable plate 607. A cleaning movable slide rail is fixed to the lower end of the cleaning frame 601. The cleaning movable slider 611 slides horizontally on the cleaning movable slide rail. The drive end of the cleaning movable cylinder 610 is connected to the lower end of the cleaning frame 601.

[0062] When the carrier plate 903 is above the cleaning frame 601, the cleaning lifting motor 605 starts, controlling the cleaning lifting screw 606 to rotate upward, so that the brush plate 603 inside the cleaning frame 601 contacts the lower end of the carrier plate 903. During the lifting process, the combination of the cleaning guide rod 608 and the cleaning guide cylinder 609 keeps the lifting movement in the vertical direction. Then, the cleaning movable cylinder 610 controls the cleaning frame 601 to move left and right, so that the brush plate 603 brushes the lower end of the carrier plate 903. During this process, the cleaning movable slide rail and the cleaning movable slider 611 keep the cleaning frame 601 moving horizontally.

[0063] The lower end of the second bracket 4 is fixed with a diluent recovery tank 612. A diluent outlet 613 is provided on one side of the drip drying frame 501, one side of the cleaning frame 601, and one side of the air drying frame 701. The diluent outlet 613 is connected to the diluent recovery tank 612. The liquid impurities, whether drip-dried, cleaned, or air-dried, will be discharged from the diluent outlet 613 and recovered into the diluent recovery tank 612.

[0064] Pushing rollers 805 are provided on both sides of the movable frame 801. The lower end of the pushing plate 803 rolls on the pushing rollers 805. A pushing guide rod 806 is installed on the movable frame 801. A pushing guide block is installed on the lower end of the pushing plate 803. The pushing guide rod 806 slides horizontally in the pushing guide block. After the carrier plate 903 is placed on the pushing plate 803, the pushing plate 803 moves horizontally along the pushing guide block and the pushing guide rod 806. Under the action of the pushing rollers 805, the carrier plate 903 is smoothly moved into the baking equipment.

[0065] The handling mechanism 9 includes a handling gantry 901, a handling lifting plate 902, and a carrier plate 903. A handling lifting cylinder 904 is installed at the upper end of the handling gantry 901. The drive end of the handling lifting cylinder 904 is connected to the handling lifting plate 902. The handling lifting plate 902 is located below the handling gantry 901. A handling hook 905 moves horizontally on the handling lifting plate 902. Both sides of the carrier plate 903 are provided with hanging ears 906. The lower end of the handling hook 905 is hooked on the hanging ears 906.

[0066] When the vehicle tray 903 needs to be moved, the transport gantry 901 moves above the vehicle tray 903. The transport lifting cylinder 904 controls the transport lifting plate 902 to move down, while the transport hook 905 moves laterally outward. When the transport hook 905 is at the same height as the hook 906 of the vehicle tray 903, the transport hook 905 moves laterally inward, so that the transport hook 905 hooks the hook 906. Then, the transport lifting plate 902 is raised under the control of the transport lifting cylinder 904, and the entire transport gantry 901 begins to move. When the vehicle tray 903 is in the position to be placed, the transport lifting plate 902 moves down again, while the transport hook 905 releases the vehicle tray 903, and the vehicle tray 903 is placed accurately and orderly.

[0067] The drive end of the lifting cylinder 904 is vertically connected to the transport transmission plate 907. The transport transmission plate 907 and the lifting plate 902 are connected by a transport guide rod 908. The transport gantry 901 is fixed with a transport guide cylinder 909. The transport guide rod 908 passes through the transport guide cylinder 909. In the vertical direction, the lifting cylinder 904 moves up and down in conjunction with the lifting plate 902 through the transport transmission plate 907. When the lifting plate 902 moves up and down, the transport guide cylinder 909 and the transport guide rod 908 keep the lifting plate 902 moving vertically.

[0068] The transport lifting plate 902 is equipped with a transport lateral slide rail 910. The upper end of the transport hook 905 is connected to a transport lateral slider 911, which slides on the transport lateral slide rail 910. A transport lateral cylinder 912 is fixed on the transport lifting plate 902. The drive end of the transport lateral cylinder 912 is connected to the upper end of the transport hook 905. When the transport hook 905 needs to hook onto or release the carrier plate 903, the transport lateral cylinder 912 controls the transport hook 905 to move horizontally. The transport lateral slider 911 and the transport lateral slide rail 910 keep the movement of the transport hook 905 in a straight state, so that it can accurately hook onto the position of the lug 906 of the carrier plate 903.

[0069] The lower ends of both sides of the transport gantry 901 are equipped with transport sliders 913. The transport gantry 901 moves back and forth according to the position to be transported by the carrier plate 903.

[0070] The carrier plate 903 has several support bars 914 in the middle. The support bars 914 are arranged at equal intervals and there are gaps between them. The impregnating liquid enters and exits through the gaps between the support bars 914 to process the transformer.

[0071] The handling mechanism 9, which is driven by the handling lifting cylinder 904, moves the dipped carrier tray 903 to the dripping mechanism 5, the cleaning and wiping mechanism 6, the air drying mechanism 7, and the moving mechanism 8.

[0072] Another type of handling mechanism differs from the one described above in that a handling servo motor is installed at the upper end of the handling gantry. The handling servo motor controls the handling lifting screw through a screw jack to achieve lifting and lowering. The handling lifting screw is connected to the handling lifting plate, thereby controlling the lifting and lowering movement of the handling lifting plate. This handling mechanism handles the carrier tray 903 from the feeding mechanism 2 to the impregnation mechanism 3.

[0073] The baking mechanism 10 includes a baking support 1001 and a baking top 1002. A baking transmission chain 1003 is provided on the baking support 1001. Baking lids 1004 are hinged to both sides of the baking top 1002. A cold air support 1005 is installed at the rear end of the baking support 1001. Several cold air fans 1006 are distributed on the cold air support 1005. The transfer mechanism 11 includes a transfer support 1101. A transfer track 1102 moves vertically on the transfer support 1101. A transfer push-out cylinder 1103 is provided in the middle of the transfer track 1102. A push-out plate 1104 is connected to the drive end of the transfer push-out cylinder 1103. The lower end of the turnover frame 12 is equipped with a movable caster 1201. Several storage layers are distributed vertically on the turnover frame 12. A storage side strip 1202 is fixed to the side of each storage layer.

[0074] The transformer, coated with the impregnation liquid, is carried into the baking mechanism 10 by the carrier plate 903. The baking transmission chain 1003 drives the carrier plate 903 to move slowly backward. After being baked by internal infrared rays, it is cured and shaped. After being removed from the baking bracket 1001, the cold air fan 1006 cools the transformer. Then, it is output to the transfer track 1102. According to the height of the storage layer on the subsequent turnover frame 12, the transfer track 1102 moves vertically to adjust the height.
