MACHINE PRINT CYCLE

The following is a typical machine print cycle with camera mounted board stop:

1. Run is selected, the printhead cover lock is engaged and the rising table

carries out a rail lifted check.

2. The camera positions itself at the board stop co-ordinates.

3. The print carriage moves to the start of the print stroke and both squeegees

drive to their set dwell height. The chase clamps are applied clamping the

chase in position.

4. The board is transported into the machine stopping at the board stop.

5. The transport belts stop running as soon as the board stop sensor detects

the board.

6. The board clamp mechanism operates, clamping the board in position and

the board stop retracts.

7. The camera carriage drives to the position determined by Fiducial 1 X & Y

co-ordinates.

8. The print carriage is driven to its enhanced start position and the appropriate

squeegee is driven down to start height.

9. The rising table carries out a rail lift check and drives up to vision height.

10. The vision data window displays the board fiducial on the left and the stencil

fiducial on the right of the split display.

11. The fiducials are located and a small blue cross with the fiducial outline

appears in the centre of each fiducial on the split display indicating success-

ful location.

12. While the camera drives to Fiducial 2 X and Y coordinates, the location of

the Fiducial 1 board and stencil fiducials are copied to the align data

structure.

13. Fiducial 2 board and stencil fiducials are located.

14. The chase clamps are de-energised and the screen actuators carry out a

rough alignment on the screen. The chase clamps are re-applied securing

the screen.

15. The camera relocates Fiducial 1 and 2. On completion, the camera carriage

drives to its home position.

16. The chase clamps are de-energised and fine alignment on the screen is

carried out. On completion, the chase clamps are re-applied.

17. The relevant squeegee is driven down to make contact with the screen with

0.5kg force.

18. The rising table drives up to the print height.

19. The appropriate squeegee is driven down to the calculated pressure setting,

as set in the board parameter menu.

20. The print carriage drives in the appropriate direction to perform a print

stroke.

21. The squeegee mechanism releases full pressure but keeps the squeegee

in contact with the stencil with 0.5kg force (hold height).

22. The rising table is lowered to separation distance at separation speed. Once

separation distance has been reached the rising table accelerates to its

normal speed, lowering the table to transport height. The board clamps are

released and the relevant squeegee is raised to dwell height.

23. The front and rear transport belts drive until the board is detected at the

output sensor and the chase clamps are released.

24. The board count, paste dispense and screen cleaner cycle counts are

incremented. If either the paste dispense or screen cleaner counts has

reached the values set by the dispense rate or clean screen rate, the

appropriate cycle is performed.
