Automatic laser-measuring system

Abstract

This invention discloses a high-precise laser auto-measurement system with laser auto- measurement instrumentation as main device. Wherein, the instrumentation comprises: a bench with a table board on its central part, a lie-cross long high-precise motion control shaft on bench top; an impulse laser emitter on the shaft that is driven by a step motor to slip; an impulse laser controller to control laser emission, and an impulse laser sensor to detect laser emission state.

Description

technical field [0001] The present invention relates to an automatic measurement system, in particular to a high-precision laser automatic measurement system that can accurately display the dimensions of each part of an object without using measuring instruments or tools to touch the object. Background technique [0002] The "high-precision" automatic measurement system on the market that does not use measuring instruments and tools to automatically measure the dimensions of each part of the object is based on the "CCD (Charge Coupled Device, Charge Coupled Device) machine vision" automatic measurement system It is the mainstream, and the principle of its application is to capture the image of the object to be measured through a charge-coupled device (CCD), and calculate the actual size based on the pixels occupied by the object to be measured. However, Using this kind of "charge-coupled device (CCD) machine vision automatic measurement system" to perform high-precision meas...

Problems solved by technology

[0005] 3. When using a charge-coupled device (CCD) for measurement, since a charge-coupled device (CCD) can only capture one-dimensional images, that is, it can only measure the appearance characteristics of a single direction, so if you want to measure When measuring appearance dimensions including height, multiple charge-coupled devices (CCDs) must be used at the same time, which will increase the difficulty of teaching and correction during use

[0006] 4. When using a charge-coupled device (CCD) for measurement, because it mainly uses different light sources to highlight the characteristics of the appearance, the conditions of use of the light source are quite strict, so it is not conducive to the measurement of objects with complex appearance, and small and diverse objects. the object

[0007] 5. When using a charge-coupled device (CCD) to measure objects, different light sources are used to highlight the appearance characteristics. Therefore, when using a charge-coupled device (CCD) to measure objects, factors such as the color and gloss of the object to be measured will be affected. Therefore, it is also easily affected by the measurement environment

[0009] 1. When the resolution of the movement position is very small, the movement speed will be too slow due to too many reading points, which affects the measurement speed and is not conducive to production operations

[0010] 2. The accuracy and resolution of the motion mechanism of the transmission system are limited, and usually cannot meet the current industry requirements, so it will cause excessive errors in the measured values

[0011] 3. There is a specific angle between the emission and reflection of the laser, so when measuring the object to be measured with a relatively complex shape, it is easy to cause the problem that the reflected laser is blocked
