1.2.2 PWB transfer unit: mechanism and parts identification
1. Pin reference
When a board is carried in and the IN sensor ① detects the board, the transport
motor ② drives the drive shaft ③ , and the transport belt ④ starts to feed the
board. At the same time, the stopper ⑤ turns on.
When the board reaches the wait stopper ⑤ , the STOP sensor ⑥ detects the
board, and the BU plate ⑦ goes up. At this moment, the board is held by the
transport belt ④, the centering pin ⑧, and the BU pin ⑨
After production finishes, the fixed board is released. When the machine ejects
the board and the OUT sensor ⑩ detects it, the board ejection process finishes.
2. Edge reference <Option>
The board loading mechanism is the same as that of the pin reference above.
When the board is fixed, the pusher Y ⑪ pushes its edges against the fixed rail
side so that the board can be positioned. Then the board is fixed with the PWB
transport belt ④ and BU pin ⑨.
The transport operation that follows is also the same as the pin reference above.
① IN sensor ⑨ BU Pin
② PWB transport motor ⑩ OUT sensor
③ Drive shaft ⑪ Pusher Y
④ PWB transport belt ⑫ BU cylinder
⑤ Stopper ⑬ BU-UP sensor
⑥ STOP sensor ⑭ BU-DOWN sensor
⑦ BU plate ⑮ Depressure valve (Edge reference option)

1.2.3 Component feeder
The component feeder has two banks located at front and rear to sandwich the PWB
transport unit. It may be a tape, stick, or tray feeder depending on the applicable
component package.
The tape feeder or stick feeder is installed to the feeder bank to feed taped
components or ones in sticks.
Tray are supplied by a tray holder, or tray feeder is installed on the rear side.
