Abstract
A replaceable heated end effector (100) can be quickly connected and disconnected to a vacuum ported tool changer (199) on a high speed machine for picking and placing electronic components. The modular end effector is made up of an adapter flange (110), a heater plate (120) and a heated tip (130). The heater plate contains one or more heating elements (410) to heat up the tip. The upper side (112) of the adapter flange mates with the vacuum ported tool changer so as to be easily removable. The adapted flange also has electrical contacts (142) to supply power to the heating elements on the heater plate. The heated tip has a vacuum pickup portion (132) that is designed to pick up the electronic components (198) and heat them while they are being transported to the placement location. There are holes or apertures (115, 125, 135) in the adapter flange, the heater plate and the heated tip that port the vacuum from the tool changer to the vacuum pickup tip. The adapter flange, the heater plate and the heated tip are all fastened together in close proximity to form a modular unit that can be easily and removably connected to the tool changer.
