Description

Technical Field

[0001] The utility model relates to the technical field of cutting devices, in particular to a circuit board fast cutting device. Background Art

[0002] Before mounting circuit boards, manufacturers sometimes need to cut mother circuit boards into specific sizes and shapes according to actual production conditions to meet product requirements. However, during the cutting process, the existing cutting devices are prone to bending and deformation of the waste edges, resulting in poor cutting results and more burrs, which seriously reduces the quality of the product and brings troubles to manufacturers.

[0003] The publication (announcement) number is CN218593195U, which discloses a circuit board cutting device for cutting circuit boards, including a base, a knife die and a support frame mounted on the base, a driving device mounted on the support frame, and a cutter assembly mounted on the driving device, wherein the driving device drives the cutter assembly to move in the vertical direction. The knife die includes a bottom plate, an adjustment plate, a plurality of knife holders, an adjustment frame connecting the adjustment plate and the bottom plate, and a positioning frame connecting the knife holder and the bottom plate. The adjustment plate is provided with a plurality of first avoidance grooves extending downward, and each knife holder is correspondingly arranged in a first avoidance groove. When cutting, the circuit board is clamped between the adjustment plate and the cutter assembly. The utility model effectively reduces the burrs on the circuit board, improves product quality, and the entire cutting process is fast, which effectively improves processing efficiency.

[0004] Although the above scheme can reduce the burrs on the circuit board, the loading and unloading of the circuit board before and after cutting requires manual operation, and the fixing operation of the circuit board before cutting is also cumbersome. The equipment is inefficient in loading, unloading and positioning the circuit board, and the cutter assembly can only be adjusted vertically and cannot adjust the cutting position when processing circuit boards of different specifications and sizes. For this reason, we propose a circuit board rapid cutting device. Utility Model Content
