Eye with Intelligence: Software Library for Camera -Guided Wafer Positioning
Share:
Ettlingen - Vision Components provides a software library for its Smart Cameras which enables camera-supported production monitoring and quality control in solar wafer production. The library features optimized positioning functions. Equipped with this software package, cameras provide users with a comprehensive robot guidance solution. The integrated image processing system detects an object's position which the camera then transfers to the plant's production robot via a data line, e.g. an Ethernet connection, enabling it to undertake all necessary adjustments. With a measuring accuracy considerably below 2 µm, the systems provide highly precise, tried and tested hand-eye coordination. Processing times below 1.0 sec are ensured even for several regions or objects, i.e. one, two, four or more wafers within one frame. Measuring accuracy and repeatability are not affected by difficult conditions, e.g. when the silicon wafers have partly damaged edges or the image background is unstable due to varying brightness. Object edges can be sorted by thickness and perpendicularity. The Smart Camera automatically sorts and selects contiguous edges. Based on these data, it computes center points and rotational positions. The function library is suitable for various camera models. Vision Components provides a tiered range of fully integrated cameras equipped with a proprietary operating system, thus allowing users to choose and implement precisely tailored solutions for any application.
Company Background
Vision Components GmbH was founded in 1996 by Michael Engel, inventor of the first intelligent camera for industrial applications. Today, it is a leading supplier in the field of industrial image processing. The Ettlingen-based company develops and distributes intelligent, network-compatible real time cameras. Due to their proprietary multitasking operating system VCRT, the devices operate without an additional PC, making them easy to integrate into almost any industrial facility. Typical application areas include quality and completeness checks, measurement technology and biometric access control.
