Photoelectric measuring device for the stepping and shaft center of a middle column sheet during automatic lamination of a transformer iron core

Abstract

The invention relates to the technical field of transformers, in particular to a photoelectric measuring device for the stepping and shaft center of a middle column sheet during automatic lamination of a transformer iron core, comprising a positioning platform for placing silicon steel sheets which are not stacked in a staggered position; A storage platform for placing stacked silicon steel sheetsthat have been stacked in a staggered position; Control means for storing target calibration data and target stepping distances related to sizes of various types of silicon steel sheets; A suction detection device is electrically connecte with that control device, and is used for suck silicon steel sheet from the positioning platform and carrying out measurement. If the measurement result matcheswith the target calibration data, the silicon steel sheet is released into the storage platform accord to the target stepping distance. The photoelectric measuring device of the center column sheet step and the shaft center when the transformer iron core is automatically laminated can improve the staggered stacking efficiency of the center column sheet and ensure the stacking quality of the center column sheet by measuring and checking the related dimensions of the silicon steel sheet before the staggered stacking.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a photoelectric measuring device for the stepping of the middle column and the center of the shaft when the iron core of the transformer is automatically laminated. Background technique [0002] The iron core of the transformer generally includes a left column, a middle column, a right column, a lower yoke and an upper yoke. In the production process of the center column sheet, it is necessary to displace and stack several silicon steel sheets according to a certain distance interval. For example, in the patent application number CN201120314442.5, the five-stage laminated transformer core requires five silicon steel sheets with matching shapes and sizes to be stacked at equal intervals, and the lateral displacement of two adjacent silicon steel sheets is step by step. equal. [0003] At present, in the production process of domestic center column sheets, the misalignment a...

Problems solved by technology

[0003] At present, in the domestic production process of the center column sheet, the dislocation and lamination process of the silicon steel sheet is mainly carried out manually with the positioning of the template, which is inefficient, and once the positioning mold is fixed, the operator will not correct the lateral dislocation after lamination again. Step-by-step measurement, if the size of any silicon steel sheet itself deviates from the preset size, it will not be found during processing, and the resulting product will have serious quality problems
