[0029] Embodiment 1: A varnish dipping device for producing electronic transformers, such as Figures 1-5 As shown, it includes a chassis 101, the top of the chassis 101 is connected with a box cover 102, a circular transparent observation plate is fixedly connected to the middle of the front side of the box cover 102 tilted upward, an air outlet pipe 103 is arranged on the left side of the top of the box cover 102, and a sensor installation port 104 is opened on the right side of the box cover 102 for installing an air pressure sensor, two gas storage tanks 105 are fixedly connected to the rear wall of the chassis 101, a lifting frame 106 for sucking gas is slidably connected in the gas storage tank 105, and a circular air outlet is opened on the top of the gas storage tank 105 for discharging the gas in the gas storage tank 105. The gas on the upper part of the lifting frame 106, a spring 107 is sleeved between the front side of the lifting frame 106 and the chassis 101, a gas pipe 108 is fixedly connected to one side of the bottom of the gas tank 105, and the top side of the gas pipe 108 is fixedly connected to the chassis 101, and an air inlet valve 1071 is fixedly installed on the side of the bottom of the gas pipe 108 adjacent to the gas tank 105, which is used to prevent the gas entering the gas tank 105 from flowing back to the chassis 101, and an air outlet valve 1072 is fixedly installed on the front side of the bottom of the gas tank 105, which is used to discharge the gas in the gas tank 105.

[0030] like Figure 3 and Figure 6 As shown, the motor 109 is fixedly installed on the right side of the bottom of the chassis 101, and the left output shaft of the motor 109 is connected to a rotating shaft 110, and the rotating shaft 110 is fixedly connected to two rotating frames 111, and the top of the rotating frame 111 is connected to a hook lock 112, and the hook lock is in the shape of a number one. The hook lock 112 is used to lock the horizontal bar in the middle of the lower part of the lifting frame 106 when the paint dipping device is not in use, so as to limit the upward movement of the lifting frame 106, and a torsion spring 113 is sleeved between the hook lock 112 and the rotating frame 111.

[0031] like Figure 2 , Figure 7 and Figure 8 As shown, it also includes a connecting rod 201, which is connected to the rear side of the box cover 102. There are two connecting rods 201. A slider 202 is slidably connected to the lower part of the rear side of the chassis 101. The rear side of the slider 202 is connected to the lower part of the connecting rod 201. The lower part of the slider 202 contacts and cooperates with the upper part of the lifting frame 106 to push the lifting frame 106 to move downward.

[0032] First, the air outlet pipe 103 is externally connected to a vacuum pump, and then the air pressure sensor is installed and fixed through the sensor installation port 104 to complete the installation work.

[0033] Open the lid 102. During the process of opening the lid 102, the rear side of the lid 102 drives the connecting rod 201 to move downward, thereby pushing the slider 202 to move downward, and then driving the lifting frame 106 to move downward. The lifting frame 106 thus squeezes the air inside the air storage tank 105, and discharges the air located below the lifting frame 106 in the air storage tank 105 through the air outlet valve 1072. The spring 107 deforms under force. Subsequently, when the lifting frame 106 moves to the bottom, the lifting frame 106 squeezes the hook lock 112 to rotate counterclockwise, and the torsion spring 113 deforms under force. Then, when the lifting frame 106 passes over the inclined protrusion at the top of the hook lock 112, the deformation of the torsion spring 113 drives the hook lock 112 to reset, restricting the lifting frame 106, and completing the preparation before dip painting. Subsequently, place the electronic transformer wire group to be dip painted on the fixture, and then immerse the entire fixture into the paint tank at the upper part of the chassis 101 to complete the placement. Subsequently, close the lid 102. During the closing process of the lid 102, the lid 102 drives the connecting rod 201 and the slider 202 to move upward to complete the reset.

[0034] Start the motor 109. The motor 109 drives the rotating shaft 110, the rotating frame 111, the hook lock 112 and the torsion spring 113 to rotate counterclockwise together. Subsequently, the spring 107 is reset under force, thereby quickly pulling the lifting frame 106 to lift and reset upward. A space is quickly created at the bottom of the lifting frame 106 located in the air storage tank 105, thereby generating negative pressure. The generated pressure difference opens the intake valve 1071, and then quickly evacuates the air in the chassis 101 through the air delivery pipe 108 to complete the preliminary extraction of the negative pressure in the chassis 101. The air enters the air storage tank 105 through the intake valve 1071 and is temporarily stored. When the lid 102 is opened, the stored gas is discharged through the air outlet valve 1072 by the downward movement of the lifting frame 106. Subsequently, start the motor 109 to drive the rotating shaft 110 and other components to reset. After completing the above steps, start an external vacuum pump to evacuate the air in the chassis 101 until the required negative pressure value for work is reached, and complete the entire dip painting operation. In summary, through the cooperation of the lifting frame 106 and the air storage tank 105, during the dip painting process, when the lifting frame 106 resets, air can be quickly extracted, and the internal pressure can be quickly reduced in a short time, thereby providing a better starting point for the subsequent operation of the vacuum pump, extending the service life of the vacuum pump, and at the same time reducing the power energy consumption. By pushing the slider 202 during the opening process of the lid 102, the lifting frame 106 is automatically driven to descend, avoiding manual pushing of the lifting frame 106 and improving the production efficiency.

[0035] Embodiment 2: On the basis of Embodiment 1, as Figure 2, Figure 9 and Figure 10 As shown in Figure 9 and Figure 10 , it further includes a connecting frame 301. The connecting frame 301 is fixedly connected to the bottom of the lifting frame 111. A circular cavity is formed at the rear side of the connecting frame 301. The upper and lower ends inside the circular cavity are smaller than the middle part of the cavity, so that two end faces are formed up and down inside. A sliding frame 302 is slidably connected to the rear side of the air delivery pipe 108. A cylindrical block 304 is fixedly connected to the bottom of the sliding frame 302. The sliding frame 302 is slidably connected to the connecting frame 301. When the connecting frame 301 moves up and down, the upper and lower ends of the connecting frame 301 are in contact and cooperation with the air guide ports 303.

[0036] When the vacuum pump is operating, a large negative pressure will be generated inside the chassis 101. Affected by the pressure difference between the air storage tank 105 and the inside of the chassis 101, the intake valve 1071 is likely to be deformed, affecting the sealing performance. To avoid the above problems, the specific operation is as follows: During the process of the lifting frame 106 descending for energy storage, it drives the connecting frame 301 located at the bottom of the lifting frame 106 to move downward. The upper end face inside the connecting frame 301 descends to contact the cylindrical block 304. Subsequently, the connecting frame 301 continues to descend, thereby pulling the cylindrical block 304 and the sliding frame 302 to move downward together, aligning the air guide port 303 with the air delivery pipe 108 and opening the air delivery pipe 108. Subsequently, during the process of the lifting frame 106 ascending to extract the air inside the chassis 101, it drives the connecting frame 301 to reset. When the lifting frame 106 is about to move to the initial position, the lower end face inside the connecting frame 301 contacts the cylindrical block 304. Subsequently, it pushes the cylindrical block 304 and the sliding frame 302 to move upward, misaligning the air guide port 303 with the air delivery pipe 108 and cutting off the intake valve 1071 from the air delivery pipe 108 to protect it. In summary, through the cooperation of the connecting frame 301 and the sliding frame 302, when the lifting frame 106 completes the preliminary extraction of the air inside the chassis 101, the air delivery pipe 108 and the intake valve 1071 are automatically cut off to protect them, preventing the one-way valve from being deformed under the influence of negative pressure, and at the same time preventing the gas in the air storage tank 105 from flowing back into the chassis 101 after the one-way valve is damaged.

[0037] Embodiment 3: On the basis of Embodiment 2, as Figure 1 , Figure 2 and Figure 11 shown, it further includes a fixing frame 401. The fixing frames 401 are symmetrically arranged on the left and right sides of the chassis 101. A cylinder 402 is installed between the fixing frame 401 and the box cover 102. The cylinder 402 is used for the opening and closing between the chassis 101 and the box cover 102.

[0038] To increase the sealing performance between the chassis 101 and the lid 102, the specific operation is as follows: the lid 102 is opened and closed by the telescopic movement of the cylinder 402, so that the lid 102 can firmly adhere to the chassis 101 when closed, thereby increasing the sealing performance between the lid 102 and the chassis 101.

[0039] Although the present disclosure has been described only with respect to a limited number of embodiments, those skilled in the art who benefit from the present disclosure will understand that various other embodiments can be designed without departing from the scope of the present invention. Therefore, the scope of the present invention should be limited only by the appended claims.
