What exactly is the complete workflow of a machine vision system?

The general workflow of a complete machine vision system is as follows: 1. The workpiece positioning detector identifies when an object has moved close to the center of the camera system’s field of view and sends a trigger pulse to the image acquisition unit. 2. The image acquisition unit, according to a pre-set program and delay, sequentially issues start pulses to both the camera and the lighting system. 3. The camera either halts its current scan and immediately resumes a new frame, or remains in standby mode until the start pulse arrives—upon receiving the pulse, it initiates a fresh frame scan. 4. Before starting a new frame scan, the camera activates the exposure mechanism, with the exposure duration pre-configured in advance.

Can our PCB optical inspection equipment measure multiple items at once?

Can our PCB optical inspection equipment measure multiple items at once?

In SMT production, multiple components are generally undetectable—can our AOI system handle this? Detecting multiple components is a significant challenge in AOI inspection, primarily due to the "uncertainty of placement." In other words, "foreign objects" could potentially appear anywhere across the entire circuit board. If these extra components only occur on component pads—specifically, if a part has been placed where it shouldn’t be—it’s relatively easy to identify. However, when customers refer to "multiple-component detection," they usually mean cases where "foreign objects" appear at **any random location** on the board. While Xinghe’s AOI system is capable of detecting such instances, there are still some practical limitations when it comes to real-world applications.

General-purpose visual inspection equipment is highly favored by the market.

General-purpose visual inspection equipment is highly favored by the market.

Since its market debut in March 2012, our company’s General Optical Inspection (GOI) product has been successfully deployed across multiple industries, including automotive electronics (such as car dashboards, multimedia systems, and fuse boxes), home appliances, laptops, automated lithium-battery production lines, and flat-panel displays. As labor costs continue to rise domestically, automated inspection equipment is gaining increasing attention from customers. Our GOI solution not only excels in image recognition but also delivers advanced capabilities like measurement, positioning, counting, and solder-joint detection. Additionally, it enables seamless automatic control of external devices and can even integrate with electrical testing systems, allowing for comprehensive electrical and visual inspections of the tested objects. As a result, GOI offers a significantly higher level of automation and efficiency compared to standalone inspection tools, earning widespread acclaim from our valued customers.

Star River Circuit Board Optical Inspection Equipment Solves Challenges in Defective Material Removal and Tin Bead Detection

Star River Circuit Board Optical Inspection Equipment Solves Challenges in Defective Material Removal and Tin Bead Detection

Material drop and solder beads are common defects in PCBA production, significantly impacting product quality. Our company’s AOI algorithm employs a comprehensive detection method that combines image comparison with advanced image feature analysis, effectively resolving the trade-off between true defect detection and false alarms. This approach ensures accurate identification of foreign objects at any (visible) location across the entire board, while keeping the misclassification rate for "multiple defects" below 0.1%. As a result, this technology is now at an internationally advanced level.
