POGO PIN MACHINE
This automated horizontal feed pogo pin assembly machine has produced over 100,000 0.5 mm pitch spring loaded "pogo pins" that can be purchased for $2,500. A magazine slides and drops the Device Under Test (DUT) plunger, spring, interface plunger, and barrel into a horizontal troth. The troth has a small troth in the bottom of the troth to keep the parts in a straight line to prevent them from becoming kittywoble and jaming in the fixture. These parts are then covered in the troth when the magazine returns to load up more parts. Then a spring loaded loaded hypo tube pushes the parts together into the crimp guide block. Then the barrel either gets crimped or roll formed to complete the assembly. A sapphire V orifice stop is retracted so the spring loaded push rod spits the assembled part out of the machine. The location of the sapphire V orifice is calibrated to precisely locate the dimple crimp. The same machine has also produced a few thousand 0.4 milimieter pitch spring probes using a smaller hole in the crimp guide block.

The figure below is a PCB used to drive the pogo pin high production machine. It was designed and procured using an internet program called PCBExpress.
The figure below is a Solid Works model of the pogo pin assembly machine "tornado". The "tornado" spins the individual parts at 700 mph. As the parts approach the speed of sound, air gets heavier and the parts shoot out of the tornado orientated into a tube.
