Abstract
A control apparatus for carrying out a spot welding operation using a robot comprises a spot welding gun having a spot welding tip, an electric drive mechanism for driving the tip, and a control unit for controlling the electric drive mechanism, in which the operation of the spot welding gun is synchronously controlled with that of the robot. The electric drive mechanism is composed of an electric drive servo mechanism comprising a servo amplifier, an electric drive servo-motor and a spot welding tip driving unit. The control unit comprises a central processing unit, a random access memory, a read only memory, a timer and an input/output interface which is operatively connected to the servo mechanism and the spot welding gun. The control apparatus further comprises an input unit, a tip position detector, a robot driving unit and a robot position detector, all of which are connected to the control unit.
