Background knowledge

At present, the automobile industry is booming, new - energy vehicles have emerged suddenly, and automotive electronic technology is constantly innovating. As the core control component of vehicles, the importance of automotive boards is increasingly prominent, which is related to the driving stability of vehicles and the comfort, entertainment and convenience of the driving and riding experience.

During the production of automotive boards, the precise detection of Pin pins is the key to ensuring product quality. Once the height difference of Pin pins exceeds a reasonable range, it is likely to cause equipment failures and bring hidden dangers to driving safety. 3D industrial cameras have the advantages of high precision, high speed, non - contact measurement, and comprehensive data collection and analysis, etc., which can fully meet the strict requirements of automobile manufacturers for the detection of Pin pin height differences, and help enterprises improve product quality and production efficiency and reduce costs.

Camera Selection

Today, I will introduce to you the application cases of Next Vision Technology's LVM2330 line - laser 3D camera in the automotive industry inspection!

The LVM2330 3D intelligent sensor has a full - frame acquisition rate of 1000Hz, and can reach up to 20000Hz by setting the Region of Interest (ROI); it has 1920 physical contour points, and can reach up to 4096 points under the condition of uniform - spaced sampling of the depth map. It is specially designed to meet the harsh production environment in the factory and various high - speed and high - volume inspection application requirements.

Test item

Detection Requirement

·Measure the height difference between the top and bottom surfaces of the PIN needle, including the inclined PIN needle.

·Detection accuracy: ±0.15mm

Detection environment and installation method.

·Scanning method: The camera is fixed, and the test sample is scanned and measured by moving along the central straight line.

·Trigger mode: Triggered by an encoder, outputting stable AB - phase differential signals.

·Communication mode: TCP/IP Ethernet.
