Manual knife type pcb board splitter

Abstract

The invention discloses a manual feeding type PCB (printed circuit board) cutting machine. The cutting machine comprises an upper guide rail, a lower support beam, two columns connected with two ends of the upper guide rail and the lower support beam and flat plates respectively supporting the columns. A cutter is arranged between the upper guide rail and the lower support beam and hung on the upper guide rail through a connector, and the top end of the connector is clamped in a sliding groove of the upper guide rail. A cutter holder corresponding to the cutter and working platforms are arranged on the lower support beam. One end of the sliding groove is connected with a spring arranged along the direction of the sliding groove, the other end of the spring is connected with a soft collision block, and both the spring and the soft collision block fall into the sliding groove and are used for colliding with the top end of the connector so as to enable the top end of the connector to rebound. The other end of the sliding groove is provided with a first magnet used for avoiding collision after the top end of the connector rebounds, a second magnet is arranged on one side, corresponding to the first magnet, of the top end of the connector, and face-to-face surfaces of the first magnet and the second magnet are identical in magnetism. Noiseless, automatic and accurate restoration of the cutter can be realized, labor intensity is reduced, and working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of electronic manufacturing equipment, in particular to a manual knife-moving PCB board splitter for separating circuit boards. Background technique [0002] Circuit boards are necessary components in electronic products. In the production process of electronic products, circuit boards need to be divided by a splitter. The circuit board splitter is a kind of machine equipment that cuts off the ribs of multiple circuit boards that are integrated, that is, the PCB board, and separates a single circuit board. [0003] The existing circuit board splitters are generally divided into manual and automatic. For the manual knife type PCB board splitter, the operator puts the circuit board to be split on the knife holder, and then slides the cutter along the slide rail. Come over, complete the circuit board splitting operation with the sliding of the cutter. However, after the cutter slides to one end of the slide r...

Problems solved by technology

However, after the cutter slides to one end of the slide rail to complete a board splitting operation, since the operator always places the circuit board with one hand and slides the cutter with the other hand, it is always necessary to move the cutter back to its original position before performing the next board splitting operation. Such manual reset operation is time-consuming and laborious, directly affects the overall work efficiency of the operation, and also increases the labor intensity of the operator
