Abstract

The invention discloses a full-automatic plastic film capacitor metal spraying machine, which comprises an automatic metal spraying machine box and a top frame, the top frame is fixedly installed at the upper end of the automatic metal spraying machine box, a screening hopper is arranged in the automatic metal spraying machine box, and the screening hopper is divided into an upper layer structure and a lower layer structure by a mesh screen in the screening hopper, namely a product metal spraying layer and a gold powder storage layer. Regular vibration is generated through a screening hopper vibration motor, so that products in a product metal spraying layer do turnover motion in the vibration direction, the products make full contact with sprayed gold powder, powder receiving is uniform and consistent, therefore the metal spraying quality is improved, a pneumatic assembly is arranged on the left side of the screening hopper, and in the vibration process of the screening hopper, a negative pressure air bag is continuously pressed, therefore, air left in the negative pressure air bag is extruded out and sprayed out through a one-way air nozzle on the right side, gold powder scattered on the bottom layer of the screening hopper is accumulated in the area close to the right side and shaken out towards the right side continuously under vibration of the screening hopper, and the gold powder is recycled.

Description

Technical field

[0001] The present invention belongs to the technical field of capacitor gold, and more particularly to a fully automatic plastic film capacitor golness.Background technique

[0002] Film capacitors have a very critical process-spray gold on the process, which is the main function to exject one layer of zinc, zinc tin alloy or lead-zinc alloy in two end faces of metallized thin film capacitor cores to make it excellent. Conductive coating. The uniformity of the spray layer, the thickness, and the thickness of the particles are relatively high, but the general use of the golfage machine in the industry can only reach the accuracy of ± 0.5mm, and the high-end product must be ± 0.2mm accuracy has a big gap. The golgotter is mainly used for metallized film capacitors and ceramic capacitors, and is suitable for the production of large and medium-sized metallized thin film capacitors.

[0003] The existing automatic plastic film capacitor golfinal technology has the following proble...
