1.2.2 PWB transfer unit: mechanism and parts identification
1. Pin reference
1) When a board is carried in and the IN sensor
①
detects the board, the PWB
transport motor
⑦
drives the drive shaft
⑧
to start transporting the board
with the PWB transport belt. At the same time, the stopper
⑨
is turned on.
2) When the board reaches the stopper
⑨
, the STOP 3 sensor detects it, then
the BU plate
⑫
moves up. The board is fixed with the centering pin
⑪
and
BU pin
⑭
which are attached on the BU plate
⑫
.
3) After the board is fixed, the next board is carried in the same manner, and it
waits at the Wait sensor
⑯
.
4) After production finishes, the fixed board is released, then the machine starts
ejecting it.
5) When the first board passes the C-OUT sensor
④
, the stopper is turned on
again and the next board is fixed.
2. Edge reference <Optional>
The board transfer mechanism is the same as that of the pin reference above.
When the board is fixed, edges of the boards are held by the stopper
⑨
pusher,
X
⑩
(in the X direction) pusher Y,
⑮
(in the Y direction) and BU pin
⑭
.
The transfer operation that follows is also the same as that of the pin reference
above.
