Automobile lamp surface shape size detection method

Abstract

The invention relates to an automobile lamp surface shape size detection method. According to the method, the control mode in which a PLC is combined with a PC is adopted, detection sensors are placed at predetermined detection points correspondingly, through the information interaction between the PLC and the PC, an electric cylinder is used to push a fixture provided with the detection sensors to a detection position, bar codes and detection data of the detection sensors are read through the PC, and analysis and processing are performed, so detection can be performed on the predetermined detection points at the same time, a three coordinates measuring instrument is used to perform point-by-point detection in a traditional detection method, the three coordinates measuring instrument does not need to be used in the method, so the detection period can be shortened, and the three coordinates measuring instrument does not need to be used, so the detection cost can be reduced, problems of long detection period, high detection cost and large-scale production mass detection incompatibility with the traditional detection method can be solved.

Description

technical field [0001] The invention relates to a car lamp, in particular to a method for detecting the shape and size of a car lamp. Background technique [0002] Today, the history of some economically developed countries has shown that: the automobile industry is increasingly showing its role as an important pillar industry. It is related to the national economy, technological progress and social modernization, occupies an extremely important position in the national economy and foreign trade, is an important field of international economic competition, and is also an important symbol to measure a country's economic strength and technological level. Automobile production is also developing towards assembly automation and the adoption of flexible production systems. [0003] Due to the increasingly fierce competition in the automobile market, domestic and foreign automobile manufacturers have realized that: when the basic models have reached saturation, only relying on bo...

Problems solved by technology

[0006] The purpose of the present invention is to provide a method for detecting the surface shape and size of automobile lamps, which can automatically detect the predetermined detection points of the lamps to be tested at one time through the interaction between PLC and PC, without the need of traditional detection methods. Point-by-point detection, the method of the present invention can shorten the detection period and improve work efficiency, and because it does not need to use a three-coordinate measuring instrument, it can reduce the detection cost and solve the problem that the traditional detection method has a long detection cycle and high detection cost, which is not suitable for large-scale The problem of high-volume inspection for mass production
