4.2 Module Protection Sensors

This session describes the main sensors that are provided for ma-

chine protection.

4.2.1 Mispicked Component Detection Sensors

These sensors are provided to detect mispicked components, etc., at

the component pick-up position for the protective purposes of the ma-

chine.

• The excitations of the beam X/Y axis, the nozzle U/D

axis, and the head rotational axis are shut off. (At the

same time, the nozzle U/D axis is braked.)

• The nozzle change axis stops rapidly after the sen-

sor has detected a mispicked component.

4.2.2 Lifted Nozzle Detection Sensors

These sensors are provided to protect the placement heads when a

vacuum nozzle is ejected out of the nozzle stocker.

When one of these sensors is turned OFF (light emit-

ted and not received), the following measures are taken.

• The excitations of the beam X/Y axis and the nozzle

U/D axis are shut off.

(At the same time, the nozzle U/D axis is braked.)

4.2.3 X-Axis Collision Detection Sensor

This sensor is provided to detect that both heads have approached

abnormally for protection of the X/Y beam.

When this sensor is turned OFF (light emitted and re-

ceived), the following measures are taken.

• The excitations of the beam X/Y axis and the nozzle

U/D axis are shut off.

(At the same time, the nozzle U/D axis is braked.)
