1.2.2 PWB transfer unit: mechanism and parts identification

1. Pin reference

1) When the first board is carried in, the IN sensor ① detects the board.

2) The IN motor ④ is driven to start feeding the board.

3) When the Wait sensor detects the board, the stopper at the exit

turns on,

the C.board chuck cylinder

and S board chuck cylinder

turn off in this

order.

4) When the stop sensor at the exit ⑲ detects the board, the machine stops

feeding it, then moves up the BU table at the exit

to position and fix the

board with this table and the centering pin at the exit

5) The second board waits at the Wait sensor ③.

6) When the C.OUT sensor at the entrance ⑦ detects the first board, the

stopper at the entrance ⑪ turns on.

7) The center motor at the entrance ⑧ is driven to start feeding the second

board.

8) When the stopper sensor at the entrance ⑥ detects the second board, the

machine stops feeding it, then moves up the BU table at the entrance ⑮ to

position and fix the board with this table and the centering pin at the entrance

⑭.

9) The third board waits at the Wait sensor ③.

2. Edge reference

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 X pusher at the

entrance ⑫, Y pusher at the entrance ⑬, X pusher at the exit

and Y pusher

at the exit

. The transfer operation that follows is also the same as that of the

pin reference above.

1.2.3 Component feeder

Totally four component feeder banks are provided: two banks located at the front

and rear of the PWB transport unit, respectively. The component supply method

varies depending on the package style of components: tape , stick or bulk.

Tapes are fed from the tape feeder, sticks are from the stick feeder, and bulks are

from the bulk feeder respectively, and all types of feeders are mounted on the feeder

banks to feed each type of components.

When using the changer table (option), the feeder bank can be removed from the

main unit of this machine for preparation.
