Machine vision systems for weld inspection comprise a sensor mounted on a robotic arm. A laser in the sensor projects a line of light across the surface of a component joint, a technique known as laser triangulation. At the same time, a high-speed camera, also housed in the sensor, captures an image of the line as an elevation profile. Through the relative motion of the component and the sensor, the system builds a 3D image of the welded seam surface.
If a job seeker conducts some job research of the manufacturing industry, he will find that U.S. manufacturing employers are seeking job candidates with skills in four areas:
Industrial logistics robots are expected to help bring about consistent delivery of quality materials and efficiency to manage food production. Industrial logistics robots are expected by industry experts to bring about a new industrial revolution like never seen before.
3D Seam Inspection. Poorly welded components break, causing products to fail. In the case of automobiles and aeroplanes, this often has disastrous consequences and costs lives. Robotic weld seam inspection and optimization is now the standard in many industries.
So is manufacturing growing in the United States? President Obama hopes so, especially in the high tech sector. But evidence of high tech manufacturing being a growing industry is still yet to be seen. At this point in time, it’s still cheaper to employ a human to do a task as opposed to investing in a robot. But what happens when it’s cheaper to buy that robot, or ship that job to a plant in China? The future looks bleak once manufacturing robotics become reasonable investments for smaller companies like Standard Motor Products.
