Compact robot for pipette calibration- small weigh module saves space

Asyril is a Swiss specialist for feeding and micro-manipulation of smallest parts and assemblies, especially for watch and electronic industry, medical technology, pharmaceuticals and cosmetics industry.

Asyril received an order from a research laboratory in bio technology for an automatic vial weighing device. The new solution had to replace manual operations whenever a large amount of samples needed to be measured to calibrate pipetting systems. Asyril built a compact table-top cell of 700 x 700 x 700 mm only comprising a Delta robot. The very compact robot cell hosts several paletts of 96 places for vials to check more than one lot without operator intervention. It has a drawer mechanism for in-feed and out-feed of pallets into the robot cell. This allows convenient and safe handling of pallets. The robot is mounted on top of the casing, which makes the cleaning of the work surface an easy thing to do. Work cycles can be programmed with a simple and intuitive programming language via a user-friendly interface. It can also be turned into an automatic sorting machine, where tight weight tolerances are a must. The space for the weighing device was very limited. Therefore Asyril decided to use the very small WMC weigh module which has a footprint of 25 by 65 mm only. This saves valuable space inside the robot cell to leave room for allocating other measuring devices or more paletts. The WMC has a capacity of 20 g which offers to mount an additional preload for a holding device if needed.

The end customer and producer were impressed by the unusual small size and high performance of the WMC weigh module. It allowed them to optimize the interior of the robot cell to leave space for hosting additional equipment in the future. FREI Technik + Systeme GmbH & Co. KG cooperates with Asyril.
