Superconducting tape packaging device

Abstract

The invention provides a superconducting tape packaging device. Two independent unwinding mechanisms of a tape unwinding mechanism unwind upper coating tapes and lower coating tapes respectively, and the remaining independent unwinding mechanisms unwind superconducting tapes. A guide wheel mechanism guides and locks the relative positions of the upper coating tapes, the lower coating tapes and the superconducting tapes. A furnace can go up and down, and is used for assembling molten electrical connection weld metal. Through up-down movement, the tapes output by the guide wheel mechanism are enabled to contact or not contact the electrical connection weld metal so as to form packaged or unpackaged synthetic superconducting tapes. An extrusion mechanism pulls the synthetic superconducting tapes out of the furnace. A winding mechanism winds the synthetic superconducting tapes pulled out of the extrusion mechanism. All points of the furnace are kept at constant temperature. Constant tension and constant speed of the tapes are ensured. The synthetic superconducting tapes are consistent in width and thickness, have no impurities, and have a smooth surface. Continuous production without shutdown is realized. An internally packaged superconducting joint with uniformly distributed contact resistance can be manufactured.

Description

technical field [0001] The present invention relates to the technical field of superconducting materials, and more specifically, to a superconducting tape packaging device. Background technique [0002] Since the first discovery of superconductivity in the laboratory by Professor Camerin Onners of Leiden University in the Netherlands in 1911, superconducting materials and their applications have been one of the most active frontier research fields in contemporary science and technology. In the past ten years, the research on superconducting power devices based on superconductivity has developed rapidly. In superconducting energy storage, superconducting motors, superconducting cables, superconducting current limiters, superconducting transformers, superconducting magnetic levitation, Remarkable achievements have been made in fields such as nuclear magnetic resonance. Superconducting strips are divided into bismuth-based and yttrium-based. Bismuth-based superconductors are ...

AI Technical Summary

Problems solved by technology

If the plating is thicker, the following problems will occur: 1. The entire superconducting strip will be defilmed, that is, the silver layer and the copper layer will fall off as a whole; 2. From the perspective of strip production, thicker copper is electroplated, so The required processing time cannot be afforded by the scale of the equipment

If the mechanical dimensions are inconsistent and the width and thickness of the strip are not uniform, new defects will easily occur during the secondary processing of the superconducting strip, which will affect the overall product quality

If the copper plating is thicker and the thickness is thicker, the following problems will occur: 1. Since the superconducting strip is flat, the section of the electroplated strip will produce an unacceptable "bone shape"; 2. A large amount of copper will be produced on the surface of the superconducting strip glitch

During the subsequent insulation processing of the superconducting strip, the burrs will break the insulation. In the use environment of the superconducting strip, the burrs will cause problems such as electric field concentration.
