INVOTEC Engineering, Inc. provides solutions designed and built as a result of understanding its customers’ business objectives.  The company installs a complete manufacturing system – capable of assembling, testing and marking a medical device ergonomically, with in-process quality checks – from a single source.

INVOTEC’s medical device assembly systems optimize putting together a product’s components.  Small parts, error-proofing and critical consequences make this a challenging environment.  The company’s experience with a wide range of production requirements and applications supports its understanding of clients’ problems, and assembly systems have been deployed in a range of fields, including medical device, defense, energy, automotive, consumer products and electronics industries.

The company’s lean cell systems include a main assembly machine, supported by preassembly and post-process testing equipment.  The typical assembly machine incorporates an indexing dial to transfer assembled components in fixtures between operations in a synchronous sequence.  The techniques used couple manual loading operations with machine vision systems to verify the correct components are loaded and assembled properly.  Pressing operations are then pneumatically operated and monitored to ensure the forces, as well as the distances the tooling travels, are within process limits.

Once a client’s product is successfully assembled, functionality and traceability becomes paramount.  Accepted devices are batch-coded with a serialized number and model identification from a laser marker, and then vision inspected before entering post-process testing.  The company records data from post-process testing operations on 100% of the devices to verify device compliance.  It also semi automatically tests the completed assembly with a servo-controlled axis integrated with an automated vision system.  These inspections verify the device is within dimensional specifications.  Functional testing confirms that resultant forces from a variable input load meet design criteria.  Finally, the device is electrically tested in a system that connects, test and disconnects.
