File Mounting

：

Figure 4.16

1.Method to mount one file:

First select one file, click “mount”, then you will enter into one mounting page, above picture is an

example of one file in mounting. See the Figure 4.16

(1) On the top-left corner shows mounting process, chip list---by the variation of blue line, you can

track process of mounting constantly.

(2) On the bottom-left corner shows some feedback during mounting process.

(3) On the top-right corner shows the status of picking and picking alignment

(4) On the bottom-right corner shows some control information

a. Air pressure of 4 nozzles

b. Placement speed, can be changed by manual during mounting

c. Non-stop mount, this is used in one-stop SMT production line, add conveyors in front and

behind,

d. Auto-eject PCB once finished, when select this option, after finished mounting task, PCB will

eject its working area automatically

e. Another control information, Continuous/Step/Pause/Eject PCB front-side manually/Stop

Continuous, the machine will obey its order and work constantly

f. Step, the machine will work one single step Pause, the machine will stop its work instantly

g. Eject PCB front-side manually, in order to catch the PCB, after PCB assembly, click this

option, PCB will eject from its feeding position. Kindly notice: After pause the machine then you

can carry out this order.

h. Stop, before click this option, you need to click “pause” first

i. Vibration Feeder: Tick this item and then the vibration motor will be on.

Manual Test

The second tab at the top of the interface opens the manual test screen. This screen contains a

convenient selection of tools to verify the operational status of most components of the NeoDen4.

Most functions of the manual test screen can also be accessed from other areas of the interface.

Figure 4.17

Function: Used for testing the basic functions, connection between software and hardware is the

mainly function, details about testing as below, see the Figure 4.17.

4.5.1 Placement head

Figure 4.18

Choose nozzle 1, nozzle 2, nozzle 3, nozzle 4 to test separately, see the Figure 4.18.

(1) The “Blow” button will release a brief jet of air from the selected nozzle. Place a finger under

the nozzle to verify operation. A small increase in positive value should appear on the screen.

(2) The “Suck” button will engage vacuum for the selected nozzle. Place a finger over the nozzle to

block airflow, and press the button. If the unit is operating correctly, you will feel the vacuum, and

the “pressure” indicator will change from a positive to a significant negative value while vacuum is

present.

(3) The “Turn left” and “Turn right” buttons activate the rotational axis of the selected nozzle.

Because rotation of the smooth black nozzles is difficult to observe, it is easiest to verify function

by watching the motion of the vacuum tubes at the top of the head.

(4) Down, after click this option, selected nozzle will descend slowly. Releasing the button causes

the nozzle to return to its upper position.

(5) The “Flash” button activates the lighting for the downward-looking •camera. Press once for the

inner lights, again for the outer lights, again for both, and a fourth press will turn the lights off.

(6) The “Photograph” button verifies operation of the downward- looking camera by moving the

head back and displaying a photograph of the table.

(7) Vacuum value 1, 2, 3, 4, Based on the testing of nozzles, you can see pressure value of each

nozzle.

The “Move Head” button allows repositioning of the head in three ways.

By using the “Visual field” method, the head can be moved precisely by clicking on the portion of

the screen relative to the center crosshairs, which indicate the current position of the camera.

Because of the extreme closeup vision of the camera, only small moves are possible with each click.

With the “Mouse Vectors” setting, the screen turns grey, and represents the entire area of movement

possible over the table. Clicking in any region of the screen allows rapid, coarse movement of the

head. This can be convenient for speeding alignment, as well as for moving the head to a more

convenient general location for the task being performed.

The “Keyboard Jog” method allows movement in of the head along the X and Y axes in .1 mm

increments. Additional keyboard controls are noted on the screen. To exit this mode, press the

Escape key.

Z Axis: When in an alignment screen, the default “camera” setting allows the visual check of X and

Y coordinates. But the selection of one of the nozzles as an alignment method allows the manual

extension of the nozzle along its 12 mm Z-axis travel. This feature is useful not only to verify

operation of the Z-axis motor, but to determine the best values for “pick height” and “place height”

in the feeder settings of a P&P program.
