Description

technical field [0001] The invention relates to the field of laser thickness measurement of stators and rotors, in particular to a measuring device applied to online thickness detection and correction of stators and rotors. Background technique [0002] The motor stator and rotor are made of multiple silicon steel sheets superimposed. The thickness of the stator and rotor is the only standard to measure whether the motor is qualified. During the production process of the traditional stator and rotor, the motor stamping machine tool will drag a fixed length of silicon steel material to the cutting device at regular intervals, and after superimposing the steel sheets to a fixed number of sheets, the stamping device will punch the stacked steel sheets forming. However, when ordinary silicon steel materials are used for production, different batches or the same batch may cause uneven thickness. When the number of superimposed sheets reaches or exceeds 100 sheets, the cumulative...

AI Technical Summary

Problems solved by technology

However, when ordinary silicon steel materials are used for production, different batches or the same batch may cause uneven thickness. When the number of superimposed sheets reaches or exceeds 100 sheets, the cumulative error generated is large, resulting in the thickness of the motor stator and rotor. Uncontrollable, pass rate drops

Traditional detection methods for the thickness of silicon steel sheets mostly use manual caliper detection, which has low measurement efficiency, and the measurement accuracy is affected by artificial readings, making it difficult to achieve high-efficiency, high-precision, real-time on-line measurement

[0003] At present, the equipment for real-time measurement of the thickness of the stator and rotor silicon steel sheet has been industrialized on the market, but the measurement accuracy of the equipment has been affected by temperature drift, that is, the laser light source will appear temperature drift with the change of the working environment temperature (referred to as temperature drift) , the temperature drift will have a great impact on the measurement accuracy

At present, there is no laser head on the market that can solve the influence of measurement error caused by temperature drift. To reduce the error caused by temperature drift, it is usually necessary to withdraw the steel strip from the roller after a certain period of time and manually operate it. It is time-consuming and labor-intensive to measure and correct the standard gauge block by laser, which seriously affects the production efficiency. Therefore, it is necessary to design a real-time correction scheme for the laser steel strip.
