Outer coating film type thin film capacitor winding machine

Abstract

The invention relates to an outer coating film type thin film capacitor winding machine which comprises a rack, a working barrel is rotationally arranged on the rack, one end of the working barrel is coaxially and fixedly connected with a first mounting disc, the other end of the working barrel is coaxially and fixedly connected with a second mounting disc, and clamping needles are arranged on the first mounting disc in a sliding and penetrating mode in the axial direction of the working barrel. A supporting plate is arranged between every two adjacent clamping needles. When the thin-film capacitor is processed, the clamping needle are firstly driven to move close to the second mounting disc, a thin film of the capacitor is clamped in the strip-shaped hole through the clamping needles, then the clamping needles are driven to rotate and wind the thin film, after the capacitor is wound and formed, the mounting cylinder is driven to integrally rotate by one station, then the thin film of the capacitor is cut off, and the clamping needles continue to rotate. A protective film is adhered to the exterior of the capacitor, after the protective film is coated, the clamping needles are pulled out of the working barrel, the capacitor freely falls off, namely, the capacitor processing and surface layer coating work is completed, and the winding machine has the effects that the capacitor can be automatically wound, and the coating operation is realized outside the capacitor.

Description

technical field [0001] The present application relates to the field of film capacitor winding machines, in particular to an outer film type film capacitor winding machine. Background technique [0002] Film capacitors use metal foil as an electrode, and it is laminated with plastic films such as polyethylene, polypropylene, polystyrene or polycarbonate from both ends, and then wound into a cylindrical capacitor. [0003] When the existing film capacitor is manufactured, the film of the capacitor is clamped on the winding rod, and then the winding rod is rotated. After the film capacitor is wound and formed on the winding rod, the winding rod is removed from the capacitor. Pull out to complete the processing of the capacitor. [0004] Regarding the above-mentioned related technologies, the inventor believes that there are following defects: after the film capacitor is wound, the capacitor is easy to adhere to dust on the surface, and it may be scratched and worn. In order to...

Problems solved by technology

[0004] Regarding the above-mentioned related technologies, the inventor believes that there are following defects: after the film capacitor is wound, the capacitor is easy to adhere to dust on the surface, and it may be scratched and worn. In order to solve the previous problem, the film capacitor after winding is required The surface is covered with a protective film. For this reason, the rotary machine for winding film capacitors is improved.
