Auxiliary process method for automatically stacking iron cores

Abstract

The invention relates to an auxiliary process method for automatically stacking iron cores. The method comprises the following steps of guiding an operator to lay an upper / lower clamping piece, a pulling plate, an insulating piece and a final-stage piece by using a laser displacement sensor, an industrial camera and an intelligent control system, and retesting after laying; using the laser displacement sensor, a laser profile measuring instrument and the intelligent control system for detecting the seam of the silicon steel sheets in real time, and if the seam distance exceeds the tolerance range or the two silicon steel sheets are overlapped, alarming and prompting; using the intelligent control system, a positioning pin on a silicon steel sheet correcting device and the positioning holes in the silicon steels sheets to punch and correct the silicon steel sheets; carrying out reference calibration on the key factors and time nodes through a calibration plate, an industrial camera, a calibration point, a temperature and humidity measuring instrument and the intelligent control system. According to the invention, auxiliary accessories for iron core stacking are more quickly and accurately laid, the condition that the seam size meets the process requirement is ensured, and the automatic correction of the positions of the silicon steel sheets in the iron core stacking process is realized.

Description

technical field [0001] The invention belongs to the technical field of transformer core stacking, and in particular relates to an auxiliary process method for automatic stacking of iron cores, which improves the stacking quality of automatic core stacking. Background technique [0002] The iron core is the basic component of a power transformer, consisting of iron core laminations, insulating parts and iron core structural parts. At present, the core stacking of transformers is mainly done manually. Manual core stacking is labor-intensive and the stacking efficiency is low, which will easily lead to problems such as increased core loss, damage to silicon steel sheets, and occupational health of personnel. [0003] When manually making the core, it is necessary to lay the insulating parts and core structural parts such as pull plates and clamps on the supporting tooling. In order to make the positioning of the core laminations accurate, the insulating parts and core structure...

Problems solved by technology

The manual benchmark measurement process requires multiple people to work together, manually measure and adjust the position, and there are problems such as low work efficiency, inaccurate measurement, and a large number of people. At the same time, the diagonal distance will be blocked by the tooling and cannot be measured, resulting in subsequent iron core stacking. Deviation in positioning
