Reducing Risk With Vision-Guided Laser Welding

InvotecMachine Vision Systems, Micro Laser Processing, News, Precision Joining

Vision-guided laser welding is a technique that combines automated inspection with traditional laser welding to increase weld quality, improve consistency, and reduce scrap. Vision guidance is used in situations where the combination of tolerance stack-ups, beam diameter, and feature size would cause inconsistent welds. This typically occurs in manufacturing environments for medical devices, automotive sensors, and other intricate products that require flawless consistency despite tight tolerances, repetitive productions, and complicated assembly processes. Vision-guided laser welding works best in applications where … Read More

Creating Contrast for Machine Vision

InvotecMachine Vision Systems, News

Most manufacturers design their product before considering their equipment needs. However, acknowledging both simultaneously can save time and money—especially when it comes to machine vision systems. That’s because vision technology relies on contrast for accuracy during inspection. Keeping this in mind when selecting product components improves performance and functionality. Here are some tricks for creating contrast your product design: Optimize lighting: design features that are unique or have a special pattern to take advantage of lighting and enhance recognition. Create … Read More

The Challenge: Increase Production While Eliminating Error One manufacturer, known for their high-quality consumer products, faced forecasts that their current production capabilities could not handle. As a result, they needed to develop a system that could better facilitate part changeover and reduce cycle times—all while maintaining the integrity of their product. In addition, the company was moving production from Europe to the US. To keep costs low, the system had to accurately assemble, inspect, and test their product with minimum … Read More
