A vacuum box 2 is arranged on the top of the base frame 1, and the upper right side of the vacuum box 2 is connected and communicated with an exhaust pipe 20. The exhaust pipe 20 can be used for an external vacuum pump to keep the vacuum box 2 in a vacuum working environment. An observation window 3 is arranged on the front side of the vacuum box 2, and an annular sealing ring is arranged between the observation window 3 and the vacuum box 2 for sealing when the observation window 3 is closed. A glue injection component 4 is arranged on the upper part of the vacuum box 2, and a clamping component is arranged inside the vacuum box 2. A vibration component is arranged between the base frame 1 and the bottom of the vacuum box 2. The colloid inside the transformer housing a can be vibrated by the vibration component, which is beneficial to eliminate the gap between the colloid and the electrical components in the transformer housing a, so that the added colloid can fill the gap, thereby achieving the purpose of reducing bubbles.

[0021] For further information, see Figure 1-Figure 3 As shown, the vibration component includes an ultrasonic generator 11, an ultrasonic probe 12 and a wire 13. The ultrasonic generator 11 is arranged at the lower part of the base frame 1, and the ultrasonic probe 12 is distributed between the base frame 1 and the bottom of the vacuum box 2. The ultrasonic probes 12 correspond to the transformer housing a respectively. The ultrasonic generator 11 and the ultrasonic probe 12 are connected by the wire 13. The ultrasonic probe 12 is installed in a vertical direction just below the transformer housing a. When the ultrasonic probe 12 is working, it can vibrate the colloid in the transformer housing a, thereby achieving the purpose of eliminating bubbles in the colloid.

[0022] For further information, see Figure 2-Figure 5 As shown, the clamping assembly includes a guide rail 5, a bidirectional screw rod 6, a driving motor 7, a clamping plate 8 and a supporting plate 9. Two guide rails 5 are arranged at the bottom of the vacuum box 2, and a pair of clamping plates 8 are arranged horizontally and slidably between the two guide rails 5. A bidirectional screw rod 6 is threadedly connected between the clamping plates 8, and the two ends of the bidirectional screw rod 6 are respectively connected to the ends of the guide rails 5 through shaft sleeves. A driving motor 7 for driving the bidirectional screw rod 6 to rotate in forward and reverse directions is arranged on the rear side of the bottom of the vacuum box 2, and the output shaft of the driving motor 7 is connected to the end of the bidirectional screw rod 6. Support plates 9 are distributed at intervals on the lower side of the two clamping plates 8 for lifting the placed transformer housing a, and the support plates 9 are alternately distributed in a staggered manner, which is conducive to avoiding each other when approaching each other to avoid interference, and is conducive to clamping and limiting transformer housings a of different models.

[0023] For further information, see Figure 4 and Figure 5 As shown, a rubber pad 10 is also included. The rubber pad 10 is arranged on the opposite side of the two clamping plates 8, which is beneficial to increase the stability of the clamping plates 8 on the transformer housing a.

[0025] When it is necessary to perform glue filling operation on the transformer housing a, open the observation window 3, and then place the transformer housing a on the corresponding support plate 9, so that the transformer housing a is located directly below the corresponding glue injection component 4. Start the drive motor 7 to drive the bidirectional screw rod 6 to rotate, and then drive the clamping plates 8 thereon to move closer to each other to clamp and limit the transformer housing a placed on the support plate 9. Close the observation window 3, and connect an external vacuum pump at the exhaust pipe 20 to realize the vacuum box 2. When the interior of the vacuum box 2 is in a vacuum environment, the glue injection component 4 can be started to fill the inside of the transformer housing a. The ultrasonic generator 11 is started so that the ultrasonic probe 12 can emit sound waves of different frequencies to the bottom of the transformer housing a, and then the transformer housing a can be vibrated during the process of injecting the colloid, so that the injected colloid can be filled more fully, avoiding the generation of bubbles and affecting the production quality of the transformer housing a. In addition, the temperature sensor 15 and the heating tube 14 are conducive to real-time monitoring of the temperature inside the vacuum box 2, so that the inside of the vacuum box 2 can always be at a suitable working temperature, which is conducive to maintaining the adhesion of the colloid, thereby achieving the purpose of reducing bubbles.
