PCB splitting machine

Abstract

The invention discloses a PCB splitting machine. The technical problems of coarse cuts and welding spot crazing or part breakage caused by cutting stress of a circuit board in the prior art is solved. The PCB splitting machine comprises a cutting table, a tool rest and a horizontal guide rod, wherein a left protecting plate and a right protective plate are arranged on the cutting table, and an upper cover plate is arranged between the left protecting plate and the right protective plate. Threads are distributed on the horizontal guide rod, a nut sleeve is arranged on the tool rest, the tool rest is in threaded connection with the horizontal guide rod through the nut sleeve, a driving motor I is arranged at one end of the horizontal guide rod and supported on the cutting table. Two ends of the horizontal guide rod are supported on a liftable support through bearing seats, and the liftable support is fixed on the cutting table. A blade for cutting the circuit board is arranged on the tool rest. The PCB splitting machine performs cutting in a feeding type advance mode, the board splitting stress of the circuit board can be decreased, smooth cuts can be ensured, and welding spot crazing and part breakage can be prevented. The PCB splitting machine is provided with the liftable support, free lifting of the tool rest is achieved, and cutting of circuit boards different in thickness is achieved.

Description

technical field [0001] The invention relates to a PCB splitter, which belongs to the technical field of PCB production machinery. Background technique [0002] At present, there are two methods of PCB splitting: machine splitting and manual splitting. The cost of manual splitting is very low, and the operation is not complicated, but there are problems such as low production efficiency and rough and defective borders. There is a board splitting machine in the prior art, which includes a horizontal guide rail and a cutter. The cutter is arranged below the guide rail, and the cutter is vertically upward. The guide rail moves up and down relative to the cutter. The sliding assembly is movably connected with the guide rail, and the sliding assembly moves back and forth along the guide rail. . When in use, the cutter is located at the lower part of the plate to be cut, and the single wheel bearing of the sliding assembly presses the upper part of the plate to be cut, thereby com...
