Our client in pharmaceutical industry required a solution to a repetitive process of placing an O-ring onto a vial. We designed and built this fixture (with two handed safety operation) to automatically place O-rings, resulting in productive workers, larger throughput and reduce failure rate.

The client presented issues with existing manual process: unsafe, repetitive motion, inflexible, slow and inconsistent. The system designed was fail-safe that allowed punching of steel arrays from any of the number of positions. The throughput was increased more than 5X. The machine was design with simplicity in mind and presented with a very intuitive user interface on the HMI.

Our client needed to automate assembly of their diagnostic cards with small membranes (3.175mm in diameter and 5mm L x 1mm W). Nexus built two such reel-to-reel, benchtop machines that punched and precisely placed the membrane on the card at multiple places. The clients cost in materials were reduced by 50% as these machines shifted the entire reel-to-reel mechanism in Y-axis so that two pieces of membrane could be punched out from one plane.

The unique requirements for this system included the need to process a single part in multiple configurations while maintaining a minimal footprint. A linear transport system carried each part to the process station that was required for the pre-selected configuration. This included precisely punching-and-placing (PnP) a clear film or a metalized foil which was then heat sealed (HS) to the part. The system also dispensed four different fluids into 20 wells in two predefined configuration.

This fixture was designed to alleviate a medical device client's concern with repetitive motion stress disorder caused by placing uncapping and capping a vial. The resulting fixture featured multiple micrometers for fine adjustments for the different sizes of vials.

During the development of real-time DNA sequencing chips a repeatable cleaning process was required. This prototype system provided solvent based cleaning of up to eight chips per cycle. To provide flexibility during process and product development multiple solvent dispensing manners were incorporated in the design. Programmable cleaning patterns were also included within the CE compliant design.

After spending large amounts of money in implementing this system to produce a drug, Nexus was hired to replicate the system. We reviewed the client process and safety requirements and built a system that was much more automated, failsafe and user friendly for integration in to other processes.

The customer required a user-friendly compact system, with fully automated process capability centered on repeatability and quality. An eight station rotary dial plate was used to transport and introduce each part to precision process stations. Magazines were provided for loading base components and unloading finished product. The machine includes pick and place, magnet placement, heat staking, dispensing of adhesive gasket (reel-to-reel), part flipping and heat sealing. Two discrete vision inspection stations provide dynamic process control and placement accuracy of key components. Fully interlocked safety enclosure provides operator safety while the Touch Screen HMI facilitates ease of control.

The requirements defined for the packing and assembly of explosive detonator caps demanded special attention to operator safety and compliance with applicable OSHA standards. A rotary cylinder provided repeatable material packing pressure for each cup. To ensure consistent performance of each device, the detonator end is crimped to the cup with precise force.

This prototype machine automated the process of placing 3uL of glue on the outside of a steel tube (approx 5mm tall x 5mm dia) which was place inside of a ceramic washer. This system dramatically improved throughput and workers quality of life.

After exhausting large amounts of monetary resources and time with another vendor, Nexus Automation was entrusted with the task of designing and building a liquid handler to isolate circulating tumor cells from blood cells. Nexus Automation designed and built two identical systems, from concept to creation, in 8 weeks at less than 20% of the cost and 4X the throughput.

This automated assembly station featured stations that were custom designed by us as well as those integrated. The system included custom stations for web handling, punches with secondary actuations, pick-n-place with intricate end effectors and leak detection, as well as integrations of web cleaning and static guard, a 4-axis Adept robot, a vision system, thermo-forming, impulse welding.
