Transformer silicon steel sheet secondary positioning device based on photoelectric detection

Abstract

The invention discloses a transformer silicon steel sheet secondary positioning device based on photoelectric detection, which belongs to the field of transformer core manufacturing. On the basis of absorbing a silicon steel sheet by a magnetic attraction force for positioning, a double-state positioning bag is introduced to clamp and fix the silicon steel sheet, the phenomenon of deviation in thepositioning and subsequent grabbing processes is avoided, the positioning precision and the subsequent lamination quality are obviously improved, and the finished product quality of the iron core isfurther improved; then, seven groups of correlation type photoelectric switches are used, a linear module is in active contact with the silicon steel middle sheet, the model and the offset position ofthe middle sheet are automatically obtained through a switching signal, and therefore, the moving distances corresponding to other side sheets and yoke sheets are judged, secondary positioning of thesilicon steel sheets is achieved, meanwhile, real-time positioning of the silicon steel sheets of different models is achieved, the labor intensity of technicians is reduced, the positioning efficiency of the silicon steel sheets is improved, and the silicon steel sheets are stacked into high-quality transformer iron cores which are reliable in precision and different in shape.

Description

technical field [0001] The invention relates to the field of transformer iron core production, and more specifically relates to a secondary positioning device for transformer silicon steel sheets based on photoelectric detection. Background technique [0002] The transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. The main components are the primary coil, the secondary coil and the iron core (magnetic core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc. According to the use, it can be divided into: power transformers and special transformers (electric furnace transformers, rectifier transformers, power frequency test transformers, voltage regulators, mining transformers, audio transformers, intermediate frequency transformers, high frequency transformers, impact transformers, instrument transformers, electronic tr...

AI Technical Summary

Problems solved by technology

It is very easy to make mistakes when the silicon steel sheet is pre-stacked. When the silicon steel sheet impacts with the positioning modules at both ends, a certain distance deviation will occur. If you are not careful, there may be a deviation, which will lead to disassembly and overlapping.

The existing transformer core pre-stacking process consumes a lot of labor and the operation efficiency is low; the mechanical action of iron core pre-stacking puts forward high requirements on the patience and care of technicians, and it is easy to make mistakes, and the silicon steel sheet There are seven forms of staggered peaks in the middle piece, and the corresponding moving distance of the side piece and yoke piece will also change accordingly, which puts forward higher requirements for the ability of technicians
