[0002] At present, the external packaging of axial lead film capacitors (such as CBB20, CL20 series) generally adopts the packaging process of wrapping 3-4 circles of sticky flame-retardant horse tape on the capacitor core with welded pins, and then filling flame-retardant epoxy resin at both ends of the capacitor.
[0003] At present, in the production process of axial capacitors, due to the pouring of epoxy resin, a certain amount of epoxy resin will be stuck on the capacitor wires. After the epoxy resin solidifies, it will be very difficult to clean the epoxy resin on the wires, resulting in a waste of labor, increased production costs, and affected product delivery. At the same time, when applying the isolation agent to the wires, if the application is uneven or missed, the missed areas of the wires will still be stained with epoxy resin. Utility Model Content

[0025] Working principle:
[0026] When in use, the isolating agent is poured into the main frame 2 from the water inlet pipe 22. When the isolating agent needs to be replaced, the isolating agent in the main frame 2 can be released through the water outlet pipe 3. A feed port 4 is provided on the main frame 2, so the wire is introduced into the equipment from the feed port 4, and the wire is passed from the bottom of the rotating wheel 18 located in the main frame 2. A guide wheel 19 is also fixed in the main frame 2. After the wire passes through the rotating wheel 18, it also passes from the bottom of the guide wheel 19 to the top, and passes through the threading shaft 20 in the main frame 2. After the wire passes through the threading shaft 20, it reaches the welding machine along the bottom of the wire wheel 15, and the wire wheel 15 is fixed to the fixing frame 17 through the bracket 16.
