In a pickup head (1) for an automatic component assembly machine a house (5) is provided, which and a transmission (27, 29) is movable in a vertical direction (z-direction) by means of a drive motor (25) and is arranged on a horizontally (x-direction) movable wagon (3). The house (5) carries several pickup devices (11), which are movably mounted in the house and during the movement of the house (5) can be made to selectively accompany this in order to pick components. Therefor, the pickup devices (11) are resiliently biassed to a pulled down position by compression springs (21) and they can further be locked in an upper position by activating solenoids (31). These have locking pins (37), which during activation engage abutments (23) of each pickup device (11). The pickup head (1) can hereby, by driven by a single motor (25) simultaneously pick several components, what gives a quick picking function and hereby a quicker mounting. Further, when mounting of a component, a pickup device can be turned to a desired angular position by activating another drive motor (39). Around the driving wheel (41) thereof runs a toothed belt (43), which simultaneously engages toothed wheels (45) slidable on the pickup devices (11). In this manner an angular adjustment is obtained by means of a single drive motor (39) acting on all the pickup devices (11). |
