Abstract

The present invention relates to an automatic inspection regulator which inspects and adjusts a printed circuit board after pressing a printed circuit board to be inspected by raising and lowering the upper press and the lower press when the printed circuit board to be inspected moves on a jig, The present invention relates to a safety device for an automatic inspection regulator for a printed circuit board and a control method thereof for preventing an accident from occurring due to a drop of an upper press during an operation, The automatic test regulator of a printed circuit board provided with an upper and a lower press to be compressed includes a sensor for detecting whether an operator is working between upper and lower presses and a controller for outputting a control signal for lowering the upper press, When the detection signal is inputted, the lowering operation of the upper press is temporarily stopped, and a danger signal is outputted And controlling so as to control, and comprising a danger signal output to output a danger signal by the control signal of the controller, it will be effective to promote the safety of workers.
