Shuttle functionality

Single conveyor = > Dual conveyor

Usually, the following right and then left

conveyor lane are used in alternation.

However, if a conveyor lane is blocked, the

other lane can also be used several times in

succession.

Dual conveyor = > Single conveyor

Usually, pickup is from the right and then the

left conveyor lane of the previous machine,

in alternation. However, if there is a problem

at one lane or if there is no board available,

pickup can also be from the other lane

several times in succession. Precondition:

the same product must be produced on both

lanes.

Shuttle modes

●

Same PCB “A” in both lanes 1 and 2 machine runs in i=placement mode or asynchronous

mode.

●

Two different PCBs “A” and “B” in lane 1 “A” and lane 2 “B” machine runs in i-placement mode

or asynchronous mode.

2. Shuttle

3. Moveable rail

4. Fixed rail

For detailed information refer to the shuttle user manual.

7.3.2 Width adjustment

1. Fixed conveyor side

2. Flexible conveyor side

3. Ball screw

4. Motor with belt system

During normal production the width adjustment is set automatically upon product change by

SIPLACE Pro. Manual width adjustment is possible by means of the station software.

The width adjustment is performed with a stepping motor and two ball screws. In a dual conveyor,

different widths are possible for the two conveyor lanes.

During reference run, the conveyor rails edges will be recognized by PCB camera.

Conveyor width is measured by counting system of the motor, if the conveyor width is adjusted

manually with the machine turned off, it may happen that the actual width and the width set in the

station software no longer match and the conveyor width will have to be set.

This can be done using the "find fiducial position" in the station software.

7.3.3 Reference run

During the machine reference run the conveyor system is initialized. This is done after the gantry

reference run is completed. The light barrier and laser light sensitivity is measured and recorded for

use during PCB recognition.

During the reference run the software checks if the rail positions have been changed and issues an

estimated position for each rail. After that the board camera drives to each of the 4 fiducials on the

conveyor rails to determine the exact position and the exact conveyor width.

7.3.4 PCB convoy mode

The TX is able to handle up to two PCBs in the placement area to reduce transport time.

Pre-condition:

●

Mode is enabled

●

PCB length is less than 175mm

●

Buffer zone light sensor is installed

A second PCB (PCB 2) is buffered in the processing area. Only PCB 1 will be processed and

populated with components.

When PCB 1 leaves the processing area PCB 2 moves to the stopper and will be processed, at the

same time PCB 3 will move into the buffer zone in the processing area.

The Convoy mode is enabled by default but can be disabled under Service – Conveyor

configuration – Lane x – Parameters.

NOTICE

Vacuum tooling

PCB convoy mode is not possible when using vacuum tooling.
