[ background of the invention ]

Circuit boards are classified into three major categories, single-sided boards, double-sided boards, and multilayer circuit boards, in which the single-sided board is the first one, components are concentrated on one side, and wires are concentrated on the other side, on the most basic PCB. Such PCBs are called single-sided circuit boards because the conductors are present on only one side thereof. The single panel is generally simple to manufacture and low in cost, but has the disadvantage that the single panel cannot be applied to a product which is too complex, the double panel is an extension of the single panel, and when the single-layer wiring cannot meet the requirement of an electronic product, the double panel is used. The multilayer board is a product developed from electronic information technology to high speed, multifunction, large capacity, small volume, thinning and light weight.

When the existing circuit board shearing device cuts a circuit board, an operator firstly places the circuit board at the cutting position of a cutting blade, then controls the cutting blade to move to cut the circuit board, and the circuit board to be cut is required to be replaced again when the operator cuts one circuit board in the cutting mode, so that the operation is complex, and the cutting efficiency is low.
