Abstract
Description
Technical Field
[0001] The utility model relates to the field of PCB boards, in particular to a PCB board component pin cutting device. Background Art
[0002] PCB, also known as printed circuit board, is the support of electronic components and the carrier of electrical connection. After the pins of electronic components on the PCB are soldered, the redundant pins need to be cut off. Now, the pins are mostly cut by automatic pin cutting devices. However, for some PCB boards that cannot be cut by automatic pin cutting devices in small batches, or unqualified PCB boards with too long pins after the automatic pin cutting device cuts the pins, manual pin cutting is still required. When manually cutting the pins, the worker holds the PCB board in one hand and the pin cutting pliers in the other hand to cut the pins. Due to problems such as the cutting angle and line of sight, the stability of the cutting quality cannot be well guaranteed. Therefore, it is necessary to design a device that is convenient for manual pin cutting and ensures the stability of the cutting quality. Utility Model Content
