Mechanical Assembly

Manufacturers operating in low volume environments face many challenges trying to design sophisticated solutions that work consistently for complex medical devices and life science instruments. High volume manufacturers, such as in the automotive industry, have been successful in virtually eliminating manufacturing defects through the use of poka-yoke, a Japanese term loosely translated as “mistake-proofing”. Poka-yoke uses techniques like locking keys, fixtures and robotics to help human operators avoid making mistakes. Paramit has developed vPoke — a patented, computer-directed assembly technology core to our zero-defect approach — that provides a dramatically higher level of control and validation for mechanical assemblies in low volume environments.

vPoke is a computer directed system that contains assembly sequences and images of parts, tools, and completed examples. It utilizes custom part trays that hold the parts in sequence, required to build a single unit. No slot in the tray is left empty, so operators can be confident there are no missing parts at the start of the build. When the operator successfully completes a step, vPoke validates the work and creates a visual image, automatically storing the information electronically for use in the device history record. vPoke allows the operator to continue with the assembly process only when the current sequence is successfully completed and the operator audibly confirms validation. By engaging the operator through interactive activities and multiple senses of sight, sound, and touch, vPoke improves the operator’s concentration and enhances their involvement.

vPoke Advantages

  • Simplifies complex assembly into hundreds or thousands of individual steps. Comparative images and sophisticated computer technology prevent operators from moving to the next step unless the previous step is completed, validated and recorded.
  • Ensures each unit is built identically using the same sequences, tolerances, and parts—regardless of the operator.
  • vPoke controls all work inputs into a basic element of work, forces conformance to established criteria and sequences, automatically and securely documents everything for easy future reference. It also provides 100% traceability of components.
  • Precisely repeatable sequences are scalable for volume and product complexity. The system can be configured as an inline process, a single workstation process, or an in-place system fed by subsystem processes.
  • vPoke technicians are trained and certified by sequence with access to build strictly controlled.
