5.1.1.4 Pump Assembly

The assembly consists of the following:

●

Pump

●

Vac Pump Enable Controller (VPEC)

●

Mounting Plate and Beam

Refer to the electrical schematic.

Power to the pump (1) comes from the M71 power supply to the 5A fused input plug (4).

In the VPEC unit (8) an enable signal DOUT 7 from ESIO#3 latches CON 1 contactor relay. The

associated control switches close; this provides mains input to the pump via plug (3).

At the base of the pump, its output has a finger guard (6) to prevent access to the moving parts.

STANDALONE MANUAL HIGH FLOW VACUUM (TQ) 12/2020 19

At the pump’s vacuum input port, a magnetic coupling (7) is used to connect to the diverter valve

air hose.

The pump and VPEC unit are mounted onto the printer’s chassis with a mounting plate beam (2).

5.1.2 Operational Sequence

With High Flow Vacuum fitted and enabled, the print sequence is as follows:

1. Print is selected.

2. High Flow Vacuum is switched ON and remains on.

3. The product is loaded; the carrier/board moves into the print station and stops at the remote

board stop and is clamped.

4. The product is raised to vision height.

5. Camera sweep occurs to collect substrate and stencil fiducials data.

6. Align chase/stencil is performed.

7. The product is raised to print height.

8. The product is printed.

9. Separate the product from the stencil.

10. The product is lowered to vision height.

11. Camera sweep (post print alignment) is performed.

12. Table moves to transport height -unload product at transport height.

13. Carrier/board moves to outroad conveyor.

14. The sequence repeats from step 3 until the batch has printed.

15. High flow vacuum switches OFF.
