Based on the CAD data of the lamp, specific measurement points are defined for initial calibration. The lamp is picked from the production line and placed inside the inspection machine onto a positioning system with six motion axes. As the metrology is done automatically according to the calibration data, the sample is adjusted inside the machine to a defined position. The positioning is done with high precision in the micron-range and very fast in all degrees of freedom for high throughput rates.
For this kind of motion, the DM401 Series Inspection Machine employs a parallel kinematic Hexapod robot from. The customized Hexapod H-820 provides outstanding precision with identical dynamic behavior in all axes, low moving net mass and high stiffness.
Flexibility in Production Lines
The use of Hexapod systems allows for an outstanding flexibility for a large variety of samples of in-line automation systems of the DM401 Series by minimizing the required space for motion robotics. The DM series excel in their high flexibility, reliability, simplicity, compact design and easy programmability. Their high accuracy combined with high speed make the DM401 Series the ideal choice for automating inspection applications.
Parallel Kinematic Robots
In a parallel-kinematic multi-axis system, all actuators act directly on a single moving platform. This means that all axes can be designed with identical dynamic properties, thus reducing the moved mass considerably. Hexapods are used for moving and precision positioning, aligning and positioning loads in all six degrees of freedom, i.e., three linear and three rotational axes.
