APPARATUS FOR PRODUCING PRINTED CIRCUIT BOARD AND METHOD FOR AUTOMATICALLY CONTROLLING WORKING WIDTH

摘要

PURPOSE: An apparatus for producing printed circuit boards and a method for automatically controlling a working width are provided to automatically control a producing system according to kinds of printed circuit boards when different kinds of printed circuit boards are produced and variably controlling a width by making transfer conveyers and working table holders being integrated when different sized printed circuit boards are produced. CONSTITUTION: The first transfer conveyer includes the first reference guide rod and the first variable guide rod between which a printed circuit board is interposed. The first power unit is installed on the first transfer conveyor and controls widths of the first reference guide rod and the first variable guide rod. A reference support member and a variable support member support the printed circuit board by receiving the printed circuit board transferred from the first transfer conveyor. A working table holder allows a mounting process to be performed on the printed circuit board. The first connecting part is installed on an end of the variable support member so as for the variable support member to be operated together with the variable guide rod when the first variable guide rod is variably operated. The second transfer conveyor includes the second reference guide rod and the second variable guide rod allowing the printed circuit board to be interposed therebetween so that the printed circuit board can be transferred when the printed circuit board is transferred from the working table holder. The second power unit is installed on the second transfer conveyor and controls widths of the second reference guide rod and the second variable guide rod. The second connecting part is arranged on other end of the variable support member so as for the variable support member to be operated together with the second variable guide rod.
