A fully automatic plastic film capacitor gold spraying machine

Abstract

The invention discloses a fully automatic gold-spraying machine for plastic film capacitors, comprising an automatic gold-spraying case and a top frame, the top frame is fixedly installed on the upper end of the automatic gold-spraying case, and a sieve hopper is set in the automatic In the hopper, the sieve hopper is divided into upper and lower layers by a mesh screen, which are the product gold-sprayed layer and the gold powder storage layer respectively. The vibrating motor of the sieve hopper generates regular vibrations, so that the products in the product gold-sprayed layer do flipping motion along the vibration direction , so as to fully contact with the sprayed gold powder, so that the powder is evenly received, thereby improving the quality of gold spraying, and a pneumatic component is installed on the left side of the sieve hopper. The air in the airbag is squeezed out and sprayed out by the one-way air nozzle on the right, so that the gold powder scattered on the bottom of the sieve hopper accumulates in the area on the right side, and is continuously shaken to the right under the vibration of the sieve hopper. Gold powder recycling and reuse.

Description

technical field [0001] The invention belongs to the technical field related to gold spraying of capacitors, and in particular relates to a fully automatic gold spraying machine for plastic film capacitors. Background technique [0002] There is a very critical process in the production process of film capacitors - gold spraying. Its main function is to spray a layer of zinc, zinc-tin alloy or lead-zinc alloy on the two ends of the metallized film capacitor core to make it have excellent performance. conductive coating. The requirements for the uniformity, thickness, and particle thickness of the coating layer are relatively high, but looking at the gold spraying machines commonly used in the industry, the uniformity of thickness can generally only reach the accuracy of ±0.5mm, which is far from the ±0.5mm accuracy required by high-end products. There is still a big gap in the accuracy of 0.2mm. The gold spraying machine is mainly used for spraying conductive layers on both...
