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

Overview Trimmed injection molded seals from a sprue using a laser cutting method that provided tight tolerances and did not pull, stretch or tear the material before cutting each gate free with no burrs. PROBLEMS WE SOLVE This medical device manufacturer had a seal product that needed to be trimmed from its mold sprues. These seals did not hold their shape, were extremely pliable and required tight tolerance cuts to make an acceptable assembly. The trimming process could not pull, … Read More
