Introduction
The VCD/Sequencer 8 (Model 6241F) automatically sequences and
inserts class A—52mm axial leaded components into printed circuit
boards (PCB).
The VCD/Sequencer 8 is available with automatic PCB handling,
Loader/Unloader. See Appendix A for Board Handling details
(Mag-to-Mag, Raw Card-to-Mag and Destacker-to-Mag).
Insertion rates up to 25,000 components per hour can be achieved by
the VCD/Sequencer 8. (See “Insertion Rate Determination.”)
Selected configurations of the VCD/Sequencer 8 are CE marked.
Functional Description
The VCD/Sequencer 8 is a single head axial lead component
sequencer/inserter that automatically inserts components from taped
input into printed circuit boards (PC boards). A product (pattern
program) is created with information pertaining to the components,
PC boards, and processing requirements. When this product is
loaded, machine operation can be started.
The VCD/Sequencer 8 sequencer modules contain dispensing heads
which cut axial lead components from input tape reels or ammo packs
and place them on the sequencer chain. The component sequence is
predetermined by a pattern program (product). The components are
then transferred to the VCD head chain for delivery to the insertion
tooling. The pattern program controls the location and orientation of
component insertion.
After insertion through the PC board, the component leads are cut
and formed (clinched) to mechanically secure them to the board. The
process continues until the product is completed and all required
axial components are in place. When the pattern program is com-
plete, the PC board is removed or transferred from the machine.
