Automatic laminating production line for transformer iron cores

Abstract

The invention relates to the technical field of automatic equipment for transformer production, and particularly relates to an automatic laminating production line for transformer iron cores. The automatic laminating production line comprises an automatic transformer iron core laminating table and a sheet feeding device, wherein a column sheet fine positioning device and a yoke sheet fine positioning device are arranged on the two sides of the automatic transformer iron core laminating table respectively, the column sheet fine positioning device is connected with a column sheet conveying device, the yoke sheet fine positioning device is connected with a yoke sheet conveying device, feeding bins for storing corresponding silicon steel sheets are respectively arranged at the starting ends ofthe column sheet conveying device and the yoke sheet conveying device; and a column sheet stacking manipulator and a yoke sheet stacking manipulator can respectively transfer each core column siliconsteel sheet and upper and lower yoke silicon steel sheets subjected to fine positioning to the automatic laminating table, so that automatic lamination of the iron cores is realized. According to theproduction line, the production efficiency is remarkably improved, the lamination cost is reduced, the attractive appearance of the iron core and the quality stability of the transformer are guaranteed, and the product quality can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of automation equipment for transformer production, in particular to an automatic stacking production line for transformer iron cores. Background technique [0002] At present, more than 1,000 transformer manufacturers in the country use manual lamination for iron core lamination, and the lamination efficiency is low. Taking a small 10kV transformer as an example, the entire iron core is made of more than 6,000 pieces of silicon steel sheets in a certain order. The lamination process is operated by 2 people. It takes more than 3 hours of work to complete the lamination of one transformer. If it is laminated one piece at a time (referred to as single lamination, the performance of single lamination core is better than that of double lamination), it will take longer time. Large-scale transformers require three or more people to work together, the lamination workload is huge and cumbersome, the stacking cycle ...

AI Technical Summary

Problems solved by technology

Large-scale transformers require 3 or more people to work together, the lamination workload is huge and cumbersome, the stacking cycle is long, and the lamination consistency is poor, and the quality is difficult to guarantee

During the stacking process, the stacking and alignment of each silicon steel sheet depends on experience and naked eye observation to maintain the stacking accuracy. The stacking workers must maintain a high degree of attention. The quality of the iron cores stacked by different workers is different. The product has a certain percentage of unqualified rate
