Microphone on Circuit Board Thru-Hole Soldering System

The cell incorporates an Adept AWC controller, two Adept robots, an Adept flexfeeder, a laser soldering system, a wire feeder, one end effector tooled to pick up three microphones independently, and another which is custom configured to spin PCB parts about their center axis. The system also includes an edge conveyor configured with a specially designed lighting system for the PCB market for thru-hole application, coupled with two vision cameras and one process control camera for operator viewing during soldering operation.

Operation is started with the flexfeeder dispensing parts under the viewing area of the first camera. Once the system has identified components in the proper orientation for pickup, the Adept Cobra 600 end effector moves into position and loads three components independently into each of its three vacuum grippers. The Cobra 600 then hands off one of the microphones to an Adept cartesian robot, located under the conveyor system. Once handed off, the Cobra 600 moves into position to take a picture of the orientation of the leads of the device. The cartesian robot then moves the microphone into position from below, and inserts the leads of the device into the circuit board. The Cobra 600 then moves into position and solders the leads from the opposite side of the circuit board. When soldering is complete, the Scara then hands off another component and the cycle starts again. When all three components are soldered, the Scara reloads its end effector with parts, and begins again. Between part loading, the conveyor indexes another component for soldering.
