Introduction

The VCD/Sequencer 8 (Model 6241F) is available in a number of

automatic board handling configurations:

Magazine-to-Magazine Configuration: Magazines contain-

ing PC boards are placed on the input Elevator (Loader) and the

PC boards are then automatically transferred into the machine

for component insertion. Once completed, the boards are

unloaded into an output magazine Elevator (Unloader). Each

Elevator includes a magazine Buffer.

• Long Buffer: 1270mm (50") for magazines 21" long (CE-

compliant)

Vacuum Bare Board-to-Magazine Configuration: Bare

PC boards are placed in a Vacuum Bare Board Loader and the

PC boards are then automatically transferred onto a 559mm

(22") conveyor, which transports them into the machine for

component insertion. Once completed, the boards are unloaded

into an output magazine Elevator (Unloader). Note: This unit

is best suited for PC boards with eyelets. This configura-

tions is not CE compliant.

Destacker/Conveyor-to-Magazine Configuration: Bare

PC boards are placed in a Destack Loader and the PC boards

are then automatically dropped onto a 736mm (29"), 1118mm

(44"), or 1473mm (58") conveyor, which transports them into the

machine for component insertion. Once completed, the boards

are unloaded into an output magazine Elevator (Unloader). The

output Elevator includes a Long or Short Buffer (as above); only

the systems incorporating the Destack Loader with the 1118mm

(44") or 1473mm (58") conveyor, are CE-compliant. Note:

This unit will not function properly when eyelets are

present on the PC board.

Magazine- OR Destacker/Conveyor-to-Magazine Con-

figuration: Magazines containing partially populated PC boards

are placed on the input Elevator/Buffer (Loader) and the PC

boards are automatically transferred into the machine for

component insertion. In addition, a second input from a Destack

Loader, mounted on either a 736mm (29"), 1118mm (44"), or

1473mm (58") conveyor, can be placed in-line after the Eleva-

tor/Buffer. This permits the flexibility of loading unpopulated PC

boards from a stack, or populated PC boards from a magazine.

Once completed, the boards are unloaded into an output Eleva-

tor/Buffer (Unloader). Only the systems incorporating the

Destack Loader with the 1118mm (44") or 1473mm (58")

conveyor, and PC boards with installed components not

exceeding 25.4mm (1") thickness, are CE-compliant.

In-Line Configuration: Machines can be connected in-line

using the internal Board Handling System (BHS) and intercon-

necting conveyors. The BHS transfers two PC boards at a time:

an unpopulated board in, and a populated board out. All Board

Handling Systems are factory configurable for either left-to-

right or right-to-left direction. This configuration is CE-compli-

ant.

For detailed vacuum bare board loader and destacker specifica-

tions, see product information sheets for these products.

2. Consult a Universal Sales Engineer for other than stated sizes.

3. Two datum holes are required. For ease of setup, the

workboard holder locator pins feature detents for PC board

datum holes located 3.5, 4.0, 5.0, 6.35, or 7.62 mm from the

front edge of the board. The maximum distance from the front

edge of the PC board to the center of the datum holes is

9.0mm.

4. A slot rather than a round hole is recommended for one locating

hole.
