3D Case | "One Road" Escort Helps Rubber Road Inspection
2025.01.14
The purpose of adhesive testing is to ensure that there are no breaks, deviations, or leaks in the dispensing process, ensuring product quality and performance. In industrial production, especially in fields such as 3C and automobile manufacturing, it is particularly crucial. 0Traditional 2D detection can only obtain planar information, but it is difficult to distinguish between glue and glue channels, and cannot perform volume measurement. Therefore, a 3D line laser contour measuring instrument is needed to achieve more comprehensive and accurate detection.
Rubber road defect detection
△ Detection requirement
Check if there is any glue accumulation or shortage in the glue path
△ Detection difficulty
1. It is necessary to simultaneously detect two rubber paths with different colors
2. The production line has fast speed and high requirements for camera frame rate
△ Measurement Instructions
Using the contour tool, calculate the height of the adhesive and use it to determine if there is a shortage or stacking of adhesive. The normal adhesive height is 1.378mm, and the stacking position height is 2.305mm
△ Plan Advantage
· Multi dimensional information acquisition, one axis scanning can obtain more adhesive road data
· High dynamic range CMOS compatible with different colors and multiple adhesive paths
· The sampling speed can reach up to 49KHz, quickly and accurately responding to
in high-speed production environments
0 Thin transparent adhesive road detection
0△ Detection requirement
Detect the width and height difference of the adhesive
0△ Detection difficulty
1. The rubber road is thin and transparent, making it difficult to obtain real data
2. Irregular rubber road and noise prone imaging at corners
△ Measurement Instructions
· According to the SOP requirements, cover the entire rubber road
with a small rectangular ROI· The farthest distance from the small rectangular area to the substrate plane is the adhesive height
· The width of the adhesive in the small rectangular area is adhesive width
· Collect data for each small rectangle and calculate the maximum, minimum, and difference values
△ Plan Advantage
· Support single frame HDR, accurate recognition of high brightness/low contrast glue paths
· Can effectively suppress multiple reflection interference and provide clear imaging of adhesive road details
