[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] See Figure 1-6As shown in the figure, an impregnation machine for producing a small power adapter in this embodiment includes a frame 1. A drying chamber 2 is welded and installed on one end of the upper surface of the frame 1, and an impregnation tank 3 is embedded and welded on the other end of the upper surface of the frame 1. A lid 4 is attached to the surface of the impregnation tank 3. A rotating mechanism 5 is fixedly installed in a through hole on the upper surface of the lid 4. A viewing window 6 is embedded and fixedly installed on the surface of the lid 4. A vacuum gauge 7 is embedded and installed on the surface of the lid 4. A support frame 8 is fixedly installed between the drying chamber 2 and the frame 1. Two electric telescopic rods 9 are fixedly installed in a rectangular through hole of the support frame 8. A vacuum pump 10 is fixedly installed on the surface of the base plate. A filter 11 is fixedly connected between the impregnation tank 3 and the pipeline of the vacuum pump 10. An air extraction valve 12 is fixedly connected between the filter 11 and the pipeline of the impregnation tank 3. An air release valve 13 is fixedly installed on the air outlet pipeline of the impregnation tank 3. A heating device 14 is fixedly installed on the surface of the base plate of the equipment frame 1. A paint storage tank 15 is fixedly installed on the heating surface of the heating device 14. A discharge valve 16 is fixedly installed at the discharge port of the paint storage tank 15. A paint extraction valve 17 is fixedly connected between the pipeline of the impregnation tank 3 and the paint storage tank 15. A control box 18 is fixedly installed at one corner of one side of the equipment frame 1.

[0021] Specifically, the equipment frame 1 serves as the supporting skeleton of the entire machine, ensuring structural stability. The drying oven 2, impregnation tank 3, support frame 8, vacuum pump 10, heating device 14, and control box 18 are all fixed to the equipment frame. The impregnation tank 3, which houses the power adapter components and insulating varnish, is the core cavity for vacuum impregnation. The tank lid 4 seals the impregnation tank 3 and provides mounting interfaces for the rotating mechanism 5, viewing window 6, and vacuum gauge 7, ensuring the airtightness of the vacuum environment. The rotating mechanism 5 drives the workpiece to rotate, improving the uniformity of impregnation, accelerating the removal of air bubbles, and allowing for multi-layer placement to improve impregnation efficiency. Furthermore, the workpiece handling process is simple and convenient; the viewing window 6 is made of transparent material, allowing operators to easily observe the paint penetration and bubble discharge during the impregnation process and monitor the process status in real time; the vacuum gauge 7 monitors the vacuum level inside the impregnation tank 3 in real time to ensure that process requirements are met and provides feedback data to the control system; the support frame 8 provides an installation position for the electric telescopic rod 9, ensuring the stability of the tank lid 4 when it is raised and lowered. The electric telescopic rod 9 raises and lowers the tank lid 4 through its telescopic movement, facilitating the handling of workpieces; the vacuum pump 10 evacuates the impregnation tank 3 by opening the suction valve 12 on the pipeline to remove workpiece air. Air within the pores creates a negative pressure environment for paint penetration. The evacuation valve 12 controls the airflow between the vacuum pump 10 and the impregnation tank 3, enabling vacuuming and pressure maintenance. The filter 11 filters out impurities such as paint mist and dust that may be carried during the evacuation process, protecting the vacuum pump 10 from contamination and extending its lifespan. After impregnation, air is introduced into the impregnation tank 3 through the vent valve 13 to break the vacuum, facilitating opening and removal of the parts. Insulating varnish is stored in the varnish storage tank 15, and the varnish is supplied to the impregnation tank 3 through the varnish extraction valve 17. Some equipment is equipped with a heating device 1. 4. Adjust the paint temperature and reduce viscosity to improve permeability. The paint extraction valve 17 controls the paint passage between the paint storage tank 15 and the impregnation tank 3 to achieve automatic paint supply. The residual paint in the paint storage tank 15 is discharged through the discharge valve 16 to facilitate cleaning or changing the type of paint. The drying box 2 can generate hot air and circulate it to heat the workpiece so that the insulating paint can be cured quickly. It can drive the workpiece to rotate so that the paint layer is heated evenly, avoiding local overheating or insufficient curing. It can also filter dust in the air to prevent contamination of the workpiece surface. It can also discharge solvent vapors volatilized during the drying process to maintain air circulation inside the box.

[0022] See appendix Figure 1-2 As shown, a latch is fixedly connected between the impregnation tank 3 and the tank cover 4, and a display screen and control buttons are embedded in the surface of the control box 18 from top to bottom.

[0023] Specifically, process parameters are set via the display screen on the control box 18, and the equipment status is displayed in real time. The control buttons on the control box are the switch for the vacuum pump 10, and the latch between the impregnation tank 3 and the tank cover 4 is responsible for securing the tank cover 4.

[0024] See appendix Figure 1-3As shown, the drying oven 2 includes an insulated box 201 welded to one end of the surface of the equipment frame 1, a door 202 hinged to the edge of the surface of the insulated box 201, a first motor 203 fixedly installed in a through hole on the upper surface of the insulated box 201, a first rotating shaft 204 fixedly connected to the output end of the first motor 203, four first C-shaped insert frames 205 welded and evenly distributed on the outside of the first rotating shaft 204, a first layered hole plate frame 206 inserted and mounted on the first C-shaped insert frame 205, an inlet fan 207 fixedly installed in a through hole on the side of the insulated box 201, an electric heating wire frame 208 welded to the surface of the inlet fan 207, a filter screen 209 welded to the surface of the electric heating wire frame 208, and an exhaust fan 210 fixedly installed in a through hole on the rear surface of the insulated box 201.

[0025] See appendix Figure 1-6 As shown, the rotating mechanism 5 includes a second motor 501 fixedly installed in the circular through hole of the barrel cover 4, a second rotating shaft 502 fixedly connected to the output end of the second motor 501, four second C-shaped insert frames 503 welded and evenly distributed on the outside of the second rotating shaft 502, a second layered hole plate frame 504 inserted and mounted on the second C-shaped insert frame 503, a placement hole plate 505 inserted and mounted on the hole plate surface of the second layered hole plate frame 504, and a plurality of U-shaped clips 506 evenly distributed and snapped into the holes of the placement hole plate 505.

[0026] Specifically, motor 501 drives shaft 502 to rotate, and layered perforated plate frame 504 and perforated plate 505 rotate accordingly. The workpiece rotates, improving the uniformity of impregnation and accelerating the removal of air bubbles. C-shaped insert frame 503 supports layered perforated plate frame 504, which allows workpieces to be placed in multiple layers, improving impregnation efficiency. Perforated plate 505 carries the workpiece, and U-shaped clamp 506 clamps the workpiece to prevent it from shifting or falling off the perforated plate 505 during rotation.

[0027] See appendix Figure 1 As shown, the control box 18 controls motor 203, motor 501, vacuum pump 10 and heating device 14.

[0028] Specifically, the control box 18 controls the No. 1 motor 203, the No. 2 motor 501, the vacuum pump 10, and the heating device 14 to perform the impregnation and drying processes according to the preset procedure.

[0029] Impregnation stage: The control box 18 starts the vacuum pump 10, draws a vacuum through the air extraction valve 12, and then opens the paint extraction valve 17 to introduce the paint liquid. The rotating mechanism 5 drives the workpiece to rotate to assist the paint liquid to penetrate. After holding the pressure for a period of time, the paint extraction valve 17 is closed.

[0030] Drying stage: The electric telescopic rod 9 raises the barrel cover 4 to above the impregnation barrel 3, transferring the workpiece on the rotating mechanism 5 into the drying chamber 2. Then the chamber door 202 is closed, and the inlet fan 207 heats and dries the workpiece through the heating wire frame 208. The first motor 203 drives the rotation, causing the workpiece to rotate as well. The exhaust fan 210 discharges solvent vapor. After the set time is reached, the machine is stopped to cool down, and the workpiece is taken out.

[0031] The operation process of this utility model is as follows: During the impregnation process, when the workpiece is clamped, the power adapter component is placed in the placement hole plate 505 of the rotating mechanism 5 and clamped and fixed with the U-shaped clamp 506 to ensure that it will not fall off during rotation. The second layer hole plate frame 504 is installed on the second rotating shaft 502 through the second C-shaped insert frame 503 to realize the placement of multi-layer workpieces. When sealing the barrel lid and evacuating the vacuum, the electric telescopic rod 9 is lowered to close the barrel lid 4 on the impregnation barrel 3 and fix it with the lock. The control box 18 starts the vacuum pump 10 and opens the evacuation valve 12 to evacuate the impregnation barrel 3. The vacuum degree is monitored by the vacuum gauge 7 to reach the process requirement value. When introducing the insulating varnish, after the vacuum degree reaches the standard, the vacuum valve is opened. Under negative pressure, the insulating varnish in the varnish storage tank 15 flows into the impregnation tank 3 through the varnish valve 17, submerging the workpiece. If the varnish temperature needs to be adjusted, the heating device 14 preheats the varnish in the varnish storage tank 15 to reduce viscosity and improve permeability. During rotation impregnation and pressure holding, the control box 18 starts the second motor 501 of the rotation mechanism 5, driving the second rotating shaft 502 to rotate the workpiece, accelerating the varnish penetration and expelling air bubbles, maintaining a vacuum state and holding it for a set time to ensure that the varnish fully fills the pores of the workpiece. During varnish discharge and vacuum breaking, after the pressure holding is completed, the varnish extraction valve 17 is closed to stop the varnish supply, and the vent valve 13 is opened to introduce air into the impregnation tank 3 to break the vacuum state, facilitating subsequent opening operations.

[0032] During the drying process, when the workpiece is transferred to the drying chamber 2, the electric telescopic rod 9 is raised to lift the barrel lid 4 and the rotating mechanism 5 as a whole, removing the workpiece from the impregnation barrel 3. The workpiece on the rotating mechanism 5 is then transferred to the first layered perforated tray 206 of the drying chamber 2 and fixed by the first C-shaped insert frame 205. When the drying chamber is sealed and heating, the door 202 of the drying chamber 2 is closed to ensure that the insulation box 201 is sealed. The control box 18 starts the intake fan 207 and the heating wire frame 208 to generate hot air, which is filtered through the filter screen 209 to remove dust. At the same time, the first motor 20 is started. 3. Drive the workpiece to rotate, so that the paint layer is heated evenly; when hot air is circulated and solvent is discharged, hot air circulates in the heat preservation box 201 to heat the workpiece and cure the insulating paint. The exhaust fan 210 runs synchronously to discharge the solvent vapors volatilized during the drying process and maintain air circulation in the box; when drying is completed and cooling is achieved, after the set drying time is reached, the control box 18 shuts down the heating device 14, the inlet fan 207, the exhaust fan 210 and the first motor 203. After the workpiece has cooled down, open the box door 202, take out the power adapter component that has completed impregnation and drying, and proceed to the next process.

[0033] Key operational points: During vacuum control, the vacuum gauge 7 is used for real-time monitoring to ensure that the vacuum level in the impregnation tank 3 meets the process requirements and avoids residual air bubbles; Regarding rotation efficiency, the rotation function of the rotating mechanism 5 and the drying chamber 2 can improve the uniformity of impregnation and the consistency of drying, and the rotation speed needs to be adjusted according to the workpiece specifications; Regarding paint management, the residual paint in the paint storage tank 15 is periodically discharged through the discharge valve 16 to facilitate cleaning or changing the type of paint, and the filter 11 needs to be cleaned regularly to prevent paint mist from clogging and affecting the performance of the vacuum pump 10.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
