Hydraulic Fin Inserter
The use of hydraulic actuators to force pins into circuit substrates results in
greater accuracy and less cost.
Referring to the figure, pins 1 held in openings 2 in support block 3 are to be
inserted in corresponding openings 4 in a substrate 5. The support block and a
base 6 holding hydraulic drive actuators 7 and pistons 8 are moved upwardly on
guides 9 to contact the substrate. Thereafter, pressure is applied through
opening 10 and along the channel 11 to force pistons 8 and actuators 7 upwardly
in the support block, driving the pins 1 into the holes of the substrate. Afterward,
the pressure is relieved, and support block 3 and base 6 are retracted
The use of a hydraulic pressure on the plurality of pistons provides a uniform
force to all pin actuators and permits a wide range of pressure adjustment.
