When converting from off-the-shelf motion technology to a customized embedded solution, a major life sciences company chose Simplexity
to minimize development risk.
Simplexity worked closely with the client’s scientists, engineers and manufacturing partners to develop a fully integrated motion sub-system. Simplexity worked on-site with the client early in the development process to gain a full understanding of the product architecture; this was critical given the technical complexity of the product and the interaction between sub-systems. Later, Simplexity played a lead role in helping the contract manufacturer achieve a repeatable, high precision assembly. Finally, we developed an end-of-line tool and database collection system to remotely manage ongoing quality.
•Translated high-level product requirements into a detailed motion sub-system specification.
•Architected a 2-axis motion sub-system capable of 10 micron repeatability including the specification of all motors, sensors, encoders, bearings, belts, and lead screw elements.
•Developed the firmware and electronics for brushless DC motor control including techniques for executing fast and accurate small moves without introducing unwanted vibration.
•Developed a manufacturing process of die-casting and post-machining to achieve highly accurate positions.
•Developed a test bench to measure accuracy and repeatability.
•The test bench was used to characterize motion performance during development, to qualify component substitutions, and to ensure out-bound assembly quality at the contract manufacturer.
