Solderless automatic welding machine of golden bracelets and welding method

Abstract

The invention provides a solderless automatic welding machine of golden bracelets and a welding method. The solderless automatic welding machine of the golden bracelets is characterized by comprising a movable clipping suite, a motor-driven platform controlling machine (15), and a welding machine, wherein the movable clipping suite is used for clipping the golden bracelet workpieces to be processed; the motor-driven platform controlling machine (15) is used for controlling and driving the movable clipping suite to conduct two-dimensional or three-dimensional motion; the welding machine is used for outputting and controlling high pulse of spot welding; the movable clipping suite comprises a motor-driven translation platform (13), a motor-driven rotating platform (12), a rotary tray (6) and a fixture (9); a welding head (10) is arranged above the fixture (9) by a cantilever; and the output end of a welding machine controller (14) is connected with the welding head (10). The automatic welding machine of the invention has the advantages of high automaticity, low energy consumption, high processing efficiency, firm welding, less material losses and the like, has small possibility of deformation, and meets the requirement that gold content in gold manufacturing industry reaches national standards.

Description

technical field [0001] The invention relates to jewelry processing equipment and a processing method, in particular to an automatic welding machine and a welding method for a gold bracelet without solder. Background technique [0002] As consumers continue to update their consumption concepts in pursuit of value preservation and appreciation of thousands of pure gold, they enter professional gold stores operated by brands and pay more attention to the fineness of gold jewelry, that is, the gold content, so as to further consolidate and develop their brand awareness. Increase investment in technology research and development and technological transformation, hoping to change some traditional crafts of gold jewelry for decades through innovation, and continuously improve the overall overall fineness and gold content of gold jewelry to meet the gold content standards promulgated by the state. Among them, the technical difficulty requirements for the manufacture of thousands of ...

AI Technical Summary

Problems solved by technology

The manufacturing process of this traditional hollow back bracelet is affected by defects such as the low gold color content of solder powder and the difficulty of controlling the amount of solder powder used by the manufacturing workers due to uneven skills, resulting in this hollow bracelet manufactured by traditional technology. The back cover bracelet cannot reach the purity required by the relevant state departments for its pure gold content

[0004] On the other hand, manual welding is inefficient and requires high technical proficiency, and high temperature heating will deform the gold bracelet
