Abstract

A method for measuring the dimensions of a metal part is used for measuring the geometrical dimensions of the smooth surface of a metal part and comprises the following steps of: A, providing a horizontally movable conveying device, wherein a detecting device for emitting visible light is disposed above the conveying device; B, causing the detecting device to emit a modulated visible light signal,causing the conveying device to convey the metal part at a constant speed v, and recording the communication time t of a visible light communication link on the detecting device; and C, calculating the dimensions L of the metal part according to the formula of L=v*t. The method for measuring the dimensions of a metal part carries out noncontact measurement in virtue of common visible light, is high in precision, low in cost, low in implementation difficulty, and hardly influenced by ambient light, and has a low environment requirement.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to the technical field of non-contact measurement of the size of metal parts, in particular to a method for measuring the geometric dimensions of smooth planes of metal parts using visible light. Background technique [0002] The optical non-contact measurement methods currently used in the size measurement of parts usually use optical measurement systems such as laser scanning or chromatographic analysis using visible light. The existing optical measurement systems are usually more complicated, and the measurement systems using visible light are also Easily disturbed by ambient light. [0003] In recent years, the rapid maturity and rapid development of LED (Light Emitting Diode) technology has given birth to a new communication technology, Visible Light Communication VLC (Visible Light Communication). The characteristics of the LED itself allow it to be turned on and off quic...
