本考案は、プリント配線基板用折溝切削装置、
詳しくは一枚のプリント配線基板を複数枚に分割
するための折溝を該基板に切削する装置に関す
る。[Detailed description of the invention] The invention consists of a groove cutting device for printed wiring boards;
More specifically, the present invention relates to an apparatus for cutting grooves into a printed wiring board to divide the board into a plurality of boards.
例えばポケツト形ラジオや卓上形電子計算器な
どの配線用に使用される小形のプリント配線基板

れ独立した複数のプリント配線をプリントすると
ともに、各プリント配線ごとに分割できるように
前記プレートに折溝を切削しておき、該プリント
配線基板に電気部品を組付ける際、前記プレート
を折溝に沿つて分割するようにしている。 For example, small printed wiring boards used for wiring pocket radios and desktop electronic calculators are printed with multiple independent printed wiring on a hard plate such as Bakelite, and each printed wiring is divided into sections. A groove is cut in the plate so that the plate can be easily cut, and the plate is divided along the groove when an electric component is assembled to the printed wiring board.
ところで、前記プレートに折溝を切削する装置
として従来は、機台に、前記折溝を形成するため
の回転カツターを回転自由に取付けるとともに、
前記基板を移送するためのツメ体を前記カツター

伴ない該ツメ体を基板の後端縁に掛止して、基板
を移送すると同時に回転カツターにより前記基板
の表、裏面に折溝を切削すべくしている。 By the way, conventionally, as a device for cutting grooves on the plate, a rotary cutter for forming the grooves is attached to the machine base so as to freely rotate.
A claw body for transferring the substrate is attached to the cutter so as to be able to reciprocate, and as the claw body moves forward, the claw body is hooked to the rear edge of the substrate, and the substrate is transferred at the same time. A rotary cutter is used to cut grooves on the front and back surfaces of the substrate.

であるから、前記回転カツターはいわゆるアツプ
カツト方式を採用するしかなく、このため折溝の
側縁にカエリが発生してプリント配線を傷つける
などの虞れが多分にあつた。 However, in the device with the above structure, the substrate is transferred by the reciprocating movement of the claw body, so the substrate cannot be transferred continuously.In other words, when the claw body moves back, the substrate is transferred. Since the transfer of the substrate is interrupted, the efficiency of the cutting operation by the rotary cutter is poor, and since the structure is such that the claw body is hooked to the rear edge of the substrate to transfer the substrate, the rotary cutter had no choice but to adopt the so-called up-cut method, and as a result there was a considerable risk that burrs would form on the side edges of the grooves and damage the printed wiring.
