In traditional industrial production, the inspection of product surface defects and dimensions is typically done manually. This method is not only limited by the technical expertise of the inspection engineers but also suffers from slow speed and low accuracy. Nowadays, most companies use machine vision technology to replace manual labor, greatly improving inspection efficiency and accuracy. In industrial production, the most common automated inspection is for surface defect detection.
Solution Overview
Leadshine Control products are equipped with an AI intelligent vision system that supports continuous trajectory movement and high-speed, precise imaging of multiple discrete points. Compared to traditional manual visual inspection, it can replace dozens of quality inspectors. Its efficiency is 2-3 times higher than fixed-point inspection equipment.
Multi-axis synchronous linkage equipment has high requirements for motor response and structural precision. The Leadshine DMC-E5032 track card (bus card) and DMC5X10 series pulse cards support multiple point movements and precise IO output, enabling multi-angle photography and image acquisition for the equipment.
It has wide applications in 3C products, semiconductor wafer inspection, electronic PCB board inspection, and new energy battery inspection.
Scheme Features
The equipment features a multi-axis linkage design, combined with the precise output and trajectory interpolation function of the Leadshine control card. Equipped with an intelligent vision camera, it can continuously capture images at high speed while the multiple axes are linked, quickly, flexibly, and accurately acquiring multiple product images to achieve 360° appearance inspection of products from multiple angles, points, and curved surfaces.
Product Advantages
Advantage 1
Smart camera + AI vision algorithm improves detection accuracy.
Advantage 2
High-speed aerial photography utilizes the precise IO function of the Leadshine control card to compare the encoder position control IO output of multiple moving axes in real time, achieving microsecond-level lag and delayed triggering.
Advantage 3
Multi-axis linkage is achieved through the development of industry-specific interpolation algorithms by Leadshine control cards. Speed planning enhances the process flexibility control, and the acceleration changes linearly throughout the entire acceleration and deceleration process, avoiding equipment vibration. The response speed is small enough to ensure precise positioning at each location.
Advantage 4
In actual equipment use, the multi-axis linkage and high-speed camera achieve a processing time of 0.07 seconds per inspection point, significantly improving efficiency compared to the old fixed-point camera's 0.14 seconds. This stable and efficient inspection capability can replace dozens of quality control personnel in production.

Solution Summary
The new generation of AOI equipment, equipped with AI intelligent vision and Leadshine trajectory control cards, combines powerful technologies to form a "multi-axis linkage visual inspection device," contributing to the healthy development and revolutionary upgrade of the inspection industry. This equipment significantly improves inspection accuracy, increases efficiency, reduces labor costs, optimizes costs, and breaks through the bottlenecks in the automated appearance inspection industry. Its highly efficient and stable performance is highly favored by major 3C electronics manufacturers and is widely used for appearance defect inspection of multi-curved 3C electronic products, such as AR glasses, mice, and watches. It is also suitable for inspecting large-area components such as tablets, mobile phone frames, and soft-pack batteries. Furthermore, it is ideal for inspecting complex and precise multi-point structural components, such as mobile phone SIM card trays, camera modules, mobile phone power buttons, and Type-C ports.
