The invention provides a high-precision self-adaptive platform for laser linear scanning. Universal wheels are arranged on the bottom surface of a bottom platform, and a lifting mechanism is vertically arranged on the top surface of the bottom platform; the balance beam is vertically fixed at the top end of the lifting mechanism and is parallel to the ground; one end of the balance beam is provided with a circular shaft which coaxially extends outwards, and the circular shaft is parallel to the ground; the laser head linkage mechanism is fixedly connected to the outer side of the circular shaft in a sleeving mode. The laser line scanning head is fixedly arranged on the bottom face of the laser head linkage mechanism; the laser head linkage structure is provided with four servo piezoelectric motors which are uniformly distributed at four corners above the laser line scanning head; and the high-precision self-adaptive platform further comprises an automatic adjusting system, the automatic adjusting system obtains measurement data of the laser line scanning head and sends a driving instruction to the servo piezoelectric motor according to the measurement data, and the servo piezoelectric motor controls a connecting rod of the servo piezoelectric motor to stretch out and draw back according to the driving instruction to adjust the angle of the laser line scanning head. According to the invention, the laser line scanning head can be adjusted without manual work above the running steel belt.
Description
technical field [0001] The invention belongs to the technical field of steel strip detection and measurement, and in particular relates to a high-precision self-adaptive platform for laser linear scanning. Background technique [0002] Due to the continuous development and progress of domestic science and technology in recent years, the demand for high-precision control and high-precision detection capabilities is also increasing, especially for continuous online profile detection capabilities for some plates that require extremely high plate shape. [0003] There are two difficult problems in the practical application of continuous online profile detection of plates. First of all, the laser linear scanning equipment has very high requirements on the levelness of the laser head itself, and it is often adjusted manually with a level gauge, but this basically cannot meet the control requirements for the actual operation of the steel strip shape detection; secondly , in order ...
