Item no. 00119633-xx Feeder module cover flap, HF/X/D3, for locations 1/3

The feeder module cover flap is installed over the component feeder area. It is designed to prevent

a head crash with an upright feeder module retainer that has not been engaged correctly. The

feeder module cover flap can also prevent the front panel of feeder modules entering the place-

ment head traveling range due to incorrect operation.

The switch for the feeder module cover flap is looped into the EMERGENCY STOP circuit. The

feeder module cover flap must be locked mechanically, which causes the switch to close the open

EMERGENCY STOP circuit.

6.14.1 Description of the component sensor

The component sensor is fixed to the bottom of the housing of the 12-segment Collect&Place

head (see Fig. 6.14 - 1

, page 330). It scans the outline of a component and checks whether there

is a component at the nozzle. It also determines the height of the component. This data can be

used to determine whether the component is in the normal position or on edge at the nozzle. Com-

ponent heights from 0.1 to 4 mm can be checked. For larger components, only the presence of

the component at the nozzle is checked.

The component sensor is configured in the package form editor on the SIPLACE Pro computer.

Every nozzle, including the special nozzles, can be scanned by the component sensor.

6.14.2 Working principle

The two following conditions must be fulfilled in order to obtain a valid measurement:

– The light beam must touch the empty nozzle tip during the calibration process.

– The nozzle tip must be inside the light beam when it is holding a component.

– Minimum nozzle length 13 mm

– Nozzle length + component height + tolerance < 17 mm

If these conditions are fulfilled, it is possible to determine whether a component is present or ab-

sent, or to measure the component height. The minimum difference in height is 100 μm.
