Pen marker head

Pen marker head

Designed to have low production and maintenance costs, this pen marker head uses an inexpensive tubular solenoid to provide four vertical pen positions. It also includes a cap/de-cap function and uses a common felt-tip marker for a refill. This pen marker head was designed and built as part of a larger development effort for a medical diagnostic device.

Production line process development

Paint Line Simulation

This project involved close collaboration with client personnel to develop an automated production line for a largely manual, proprietary process with the goal of dramatically increasing throughput and product consistency. It involved preliminary design of operator work stations, conveyor line layout, multiple cure oven designs, a product carrier system, and stacking/de-stacking stations. A process flow simulation was done to optimize workflow and conveyor layout between process stations.

Prototype thermal platen

Prototype thermal platen

Designed and fabricated in-house, this thermal platen system was part of a breadboard used to test performance and feasibility of a new production process for integrated circuits. Precision-controlled temperature stations, used in assembly and testing, were part of a bigger development of a new electronic chip production machine.

Sensor test stand

Sensor test stand

This test and calibration fixture was designed and built in-house to support development of a sheet media sensor module. Servo-motor drives allow adjustment of operating parameters with options for continuous or swatch feed of test media.

Wire End Hook Bending Machine

Wire Bender Layout

Designed a machine to bend a hook on one end of a pre-stripped length of wire. It was designed for manual feed by an operator with up to 30 piece/minute throughput. The design reduces repetitive motion injuries associated with manual bending of hook ends on wire leads. It uses fully pneumatic operation for actuation and control and supports a variety of mounting configurations.
