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.

The tape feeder loaded with taped components, bulk feeder, and stick feeder

loaded with components in sticks are positioned and secured by the fixing plate

② , fixing plate B ③, and lock shaft ④ .

The tape feeder is driven by the drive cylinders ⑤ .

The position label ⑥ is used to determine the position at which each feeder is

installed.
