Description

Technical Field

[0001] The utility model relates to the technical field of PCB board production, in particular to a PCB board rough material cutting machine. Background Art

[0002] In the field of electronic manufacturing, printed circuit boards (PCBs) are important basic components of various electronic devices. Cutting of PCB raw materials is a key step in the PCB manufacturing process. The cutting process mainly involves cutting large pieces of raw materials into single or multiple PCB modules according to design requirements. The cutting accuracy and efficiency of raw materials directly affect the subsequent production process and the performance of the final product.

[0003] There are some problems in the operation of traditional PCB board rough material cutting machines. First, due to the various sizes of PCB board rough materials, the clamp design of traditional cutting machines often cannot adapt well to rough materials of different sizes, which leads to easy deviation or instability during the clamping process, thus affecting the cutting accuracy. For example, the prior art CN210732587U discloses a PCB board rough material cutting device, including a base, a clamping rod, a limit plate and a screw rod B; a cutter A is welded on the top of the rear side of the base, a rotating shaft passes through the upper left corner of the base, a cutter B is arranged on the rear side of the base, the rotating shaft passes through the bottom of the cutter B, a handle is welded on the top of the cutter B, and a clamping rod is arranged horizontally above the top of the base; the screw rod A is symmetrically and vertically penetrated on the left and right sides of the clamping rod.
