[0007] Preferably, the vacuum cut-off valve can accurately open or cut off the vacuum path between the vacuum pump and the epoxy vacuum chamber, enabling the operator to flexibly control the time and intensity of the vacuum treatment according to actual needs, which helps to ensure that the epoxy resin is degassed under the optimal vacuum conditions and improve the potting quality. The epoxy interface provides a stable delivery channel for the epoxy resin, allowing the epoxy resin to smoothly enter the epoxy vacuum chamber. The lifting support platform can be adjusted in height according to different specifications of ignition coils and potting requirements, improving the versatility and flexibility of the device and reducing the production cost. The conveying assembly can accurately send the ignition coils to be potted into the potting area and can adjust the speed according to the production rhythm.

[0008] As a preference, vacuum pumps for extracting vacuum to prevent epoxy from foaming are installed at the rear ends of both groups of vacuum cut-off valves. A vacuum negative pressure gauge for detecting the epoxy vacuum chamber is installed at the center of the top end of the vacuum cut-off valve.
