Design of rapid detection system for appearance defects of slender bamboo and wood round bars
A dual laser automatic detection system was designed to address the appearance defects such as surface pits and cracks in the blank of slender bamboo and wood round rods.In terms of mechanical structure,a load chain was used to translate the slender bamboo and wood round rod as a whole,and roll under an elastic pressure plate.A symmetrical arrangement of double lasers was obliquely incident on the joint between the pressure plate and the round rod,achieving double spiral scanning and gap detection of the surface of the bamboo and wood round rod;the control part was mainly composed of Siemens S7-200 Smart PLC,and a digital chain synchronized with the physical chain was designed for parallel control.The test results showed that the system had a zero miss rate compared to manual detection,and had the characteristics of low cost,high efficiency,high reliability,and ease of use.It could effectively solve the problem of initial screening of surface quality of slender bamboo and wood round rod blank.
