Assembly line of medium-high temperature solar thermal-collecting tube assembly

Abstract

The invention discloses an assembly line of a medium-high temperature solar thermal-collecting tube assembly. The assembly line of the medium-high temperature solar thermal-collecting tube assembly comprises a feeding conveying mechanism, an assembly spot welding worktable, an argon arc ring welding worktable, a laser ring welding worktable and a finished product conveying line, wherein the feeding conveying mechanism is used for conveying a coated steel tube and a glass tube; during a conveying process, dimensional measurement and positioning installation of a getter and a getter box can be performed by a material measuring mechanism and a tool positioning mechanism; then, the materials are manually lifted to the assembly spot welding worktable to perform assembly positioning, and further, spot welding of Kovar at both ends of a corrugated tube and the coated steel tube and the corrugated tube and the glass tube is realized; then, the materials are automatically fed to the argon arc ring welding worktable to perform automatic argon arc ring welding, are automatically fed to the laser ring welding worktable to perform laser ring welding, and then, are automatically charged to the finished product conveying line to convey a finished product. The assembly line of the medium-high temperature solar thermal-collecting tube assembly disclosed by the invention has the advantages that the degree of automation during an assembly process of the medium-high temperature solar thermal-collecting tube assembly can be improved, and the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to an assembly line, in particular to an assembly line for medium and high temperature solar heat collecting tube assembly. Background technique [0002] At present, most of the assembly of medium and high temperature solar collector tubes in China is done manually and lacks automation. If there are too many artificial factors, the quality of the products will be uneven and the efficiency will be very low. The medium and high temperature solar collector tube is used for photothermal power generation. Its structure is double-layer double-ended opening. It is a stainless steel tube with a diameter of 70 mm and a length of 4060 mm. The glass tube with a diameter of 125mm is sealed and connected by a bellows, and then sealed by vacuum exhaust. It uses high-temperature oil as a heat-conducting medium. Compared with ordinary medium and low-temperature heat collecting tubes, its structure is different. Thermal expansion performance has ...
