7.9 Feeder cover flap

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

crash with an upright feeder retainer that has not been engaged correctly. The feeder cover flap

can also prevent the front panel of feeders entering the placement head travelling range due to

incorrect operation.

The feeder cover flap is available in two versions: one for location 1 or 3 and one for location 2 or 4.

The switch for the feeder cover flap is looped into the emergency stop circuit. The feeder cover

flap must be locked mechanically, which causes the switch to close the open emergency stop cir-

cuit.

7.10.1 Description of the functions of the component sensor

Component sensor (part no. 00118021-01)

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

head (see Fig. 7.10 - 1

). It scans the outline of a component and checks whether there is a com-

ponent 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. Component

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

ponent 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.

7.10.2 Measuring conditions

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.
