How to produce on a standard scale high in operations and production of companies is a problem that each manufacturing company must solve. Automated production generally includes two parts: vision system and mechanical execution. In high-precision visual alignment systems, the UVW alignment platform is a relatively commonly used mechanical actuator. The UVW alignment platform, also known as the XXY and XYR alignment platform, belongs to a movement mechanism parallel to three axes. The UVW platform can make a device that makes a rotation movement at any time of the plane and can be translated in any direction. Currently, it is widely used in exhibition machines, collage machines, mask print machines, the alignment of the brochure, the installation of parts, the PCB drilling machines,LCD Inspection of lighting characteristics, cutting machine, patch machine (LCD / FPC), screen printing machine and other occasions.
In terms of selecting the vision system adapted to the UVW, VisionBank SVS Intelligent Vision System platform manufactured by VisionBank is a good choice.
The UVW platform and the SVS VisionBank SVS Vision System are connected, which can quickly carry out high precision correction work.
Characteristics of the VisionBank SVS Intelligent Visionbank Vision System
1. The multi-caméra combination application reaches high precision for large products and high repeated positioning precision.
2. Multi-caméras correspondence applications can be compatible with positioning detection of large and small products, and can be adapted to 1 to 8 cameras depending on the detection requirements.
3. The VisionBank SVS tool library can meet various visual needs, such as positioning, detection, identification, measurement, etc. elements.
4. Completely compatible with traditional robots and various PLC control systems to reach transparent mooring
5. Draft and drop between tools can reach digital, results and quick image links.
6. The tool group can be reused and shorten the time for the development of applications.

When using the tool (UVW Platform Move) the product shifts X, Y and θ are directly converted to the movement of each UVW platform engine.
Multi-Camera VisionBank SVS Multi-Camera Application
In common high-precision alignment projects for large products, multi-limited positioning is mainly adopted. The most common include positioning with two cameras, three cameras positioning, four cameras positioning, etc., glass, liaison to liquid crystals, AFC, FPC link, positioning prior to the pre-printing of solar cells, alignment of the printed circuit, etc.
The VisionBank SVS Intelligent Visionbank Vision System has developed one (virtual image unit) for multi-limited applications. Multi-caméras geometric elements are converted into virtual images by position calibration to form a unified coordinate system, and the product center point, product lag, global multi-caméras and other content is calculated in (virtual image unit).
Visionbank SVS assistance tools to position development
The product center and the platform rotation center have different axes. The relative positions of the two are calculated by the tool (three -point calculation rotation center).
The product center has different axes of the platform rotation center. During the calibration of the angle shift, it will cause secondary differences in positions X and Y; The original calibration method is: compensate for the angle of the first photo and compensate for the X and Y positions for the second photo; Now, the new X and Y coordinate positions after the calibration angle can be calculated by the tool (rotation point around a fixed point) and the compensation can be carried out in a single test.
Case of application of the UVW platform
