1. Machine Overview

Machine Movement During Operation

The movement of the machine when operation is started is explained below.

1. Board check

When the START button is pressed, a check is

made of whether a board is present on the

conveyor. If a board is not present, a request

signal is sent to the previous machine in the

line, and if a board is available, board loading

is performed as detailed in step 2. If a board

is already present on the conveyor, nozzle

change is performed as detailed in step 3.

2. Panel loading

When the panel available signal is received

from the previous machine in the line, the in-

conveyor shuttle moves to the panel loading

position and the panel is loaded onto the

shuttle. The shuttle moves the panel to the

main conveyor position. The panel travels

from the shuttle along the main conveyor

until it reaches the stopper. The panel is then

clamped in position, raising it to production

height.

3. Nozzle change

Nozzle change is performed as required for

the production program in use. Nozzles (or

mechanical chucks) are selected from those

available in the nozzle station.

4. Mark reading

When nozle change is complete, the skip and

fiducial marks on the board are now

inspected by the mark camera attached to the

placing head.

5. Pickup and inspection

With mark reading complete, the parts can

now be picked up. The head rotates, and the

16 nozzles (A to P) sequentially pick up the

required parts from the supply unit. Part

inspection is performed on the fly as the

rotation of the head moves each nozzle in

turn to the position of the camera prism.

Parts for which a problem was detected are

rejected to the reject parts box, and recovery

is performed in line with the settings made

by the operator.

6. Placement

After passing over the camera, the placing

head moves to the board to place of the parts.

Placement, like pick-up, is also performed

sequentially starting from head A. The head

returns to pick up more parts, repeating steps

5 and later, until the machine has carried out

all of its placement sequences.

7. Panel unclamping and unloading

When production of the panel is finished, the

panel is unclamped and conveyed onto the

out-conveyor. The panel available signal is

sent to the next machine. Panel unloading

commences upon receipt of a panel request

signal from the next machine. The panel

stopper is lowered, and the panel is

unloaded.
