Abstract
An automatic circuit adjusting system comprises a circuit adjusting tool assembly. The circuit adjusting tool assembly is movable to adjust different orientations of circuit elements. The circuit adjusting tool assembly has a plurality of adjusting tools. The circuit adjusting tool assembly is controlled in its movement and selection of adjusting tools by means of a microprocessor based controller. The controller is so programmed as to shift the circuit adjusting tool assembly to different orientations of circuit elements on a printed circuit board in order according to a preset order. The controller is also preset to schedule selection of the desired one of the adjusting tools corresponding to the position of the circuit adjusting tool assembly. According to the preferred construction, the circuit adjusting tool assembly comprises a single common driving motor for driving a plurality of the adjusting tools. Driving torque of the driving motor is distributed to the respective adjusting tools through a common power train that drives all of them at the same speed and magnitude. The adjusting tools in the circuit adjusting tool assembly are thrustingly movable in an axial direction to engage with their respective one of the cirucit elements to be adjusted. The adjusting tools are normally placed in an idling position and shifted to an active position to engage with the corresponding cirucit elements when selected by the controller.
