Description

Technical Field

[0001] The present invention relates to the technical field of pole-mounted switch assembly production, and in particular to a fully automatic pole-mounted switch assembly production line. Background Art

[0002] With the continuous advancement of smart grid construction and the continuous improvement of the automation level of distribution networks, the market demand for pole-mounted switches, as key equipment for circuit opening and closing control and protection in distribution networks, is showing a rapid growth trend. At the same time, the power system has put forward higher requirements for the reliability, consistency and production efficiency of pole-mounted switches. The traditional production model has gradually become unable to meet the needs of modern large-scale production, and innovation and upgrading of production processes and equipment are urgently needed. At present, the assembly and production of pole-mounted switches still rely on a combination of manual operation and semi-automatic equipment to a certain extent. Its main working process is: manually positioning and assembling the shell, pole, mechanism and other components, relying on manual alignment and fixation of the components during the assembly process, and manually operating the equipment to open and close the switch during the running-in process to eliminate mechanical clearance. During the testing process, manual operation of the test instrument is required to test the mechanical properties, pressure resistance and other indicators one by one. When the switch is offline, the nut removal and finished product handling are mainly completed manually. The connection between the various processes in the entire production process mostly relies on manual material transfer. At present, the assembly of pole-mounted switches generally adopts manual assembly or semi-automatic assembly, and the assembly of individual components is realized by separate equipment. This process is relatively complicated, the labor cost is high, the practicality is poor, and the operation is cumbersome. For this reason, we propose a fully automatic pole-mounted switch assembly production line. Summary of the Invention
