SJ50 Overview

Description The SJ50 is a machine vision system for the inspection of Pre and Post-reflow

Surface Mount Technology (SMT) components on Printed Circuit Boards (PCBs).

SJ50 Tasks The SJ50 performs the following tasks:

• Checks the boards to ensure that the components are present, not skewed

and are located properly in the X and Y directions. • Checks component polarity if clear orientation marks are present on the

component body. Character markings on components are also be checked for.

• Graphically display component placement X and Y offset distribution at the end of each board inspection.

• Inspect post-reflow component solder joints and report joint errors if they exist.


5186-4070-02 6

SJ50 Machine Cycle

Description In an inspection cycle, a PCB:

• enters the system from the upstream machine • is clamped • is then inspected • is released immediately if there are no board errors. • if there are errors, the operator may view them before the board is released.

Electrical Safety

Electrical Enclosure

Live power and control circuits are situated in various parts of the machine.

• The Mains Transformer is situated at the side of the machine and should not be accessed unless the power to the machine is isolated.

• The Main Control Panel is accessed through the two rear doors, which are electrically interlocked.

• When in the Off position the machine only has mains voltage on the primary side of the Main Isolator.

Emergency Stop Loop

The Emergency Stop (E-Stop) is designed according to the relevant safety standard. It is controlled using a Pilz class IV safety relay. The Emergency stop circuit has the following attributes associated with it

• During an E-Stop, power is removed from all motors including conveyors and XY Table. It also causes the pneumatic circuits to lose power (except if the Maintenance Key Switch is turned on).

• E-Stop overrides all modes of operation within the SJ-50 machine, with the exception of Maintenance Mode.

• The E-Stop of the SJ50 machine is clearly visible and identifiable. It is a red button at the front right hand side of the machine and is activated by pushing down on it once.

• Raising the front hood has the same effect as pressing the E-Stop. • When power is removed from the system the E-Stop is activated

automatically and must be reset on powering the machine back up. • On startup, NO uncontrolled motion can occur.
