Description

Technical Field

[0001] The utility model relates to the technical field of PCB production, in particular to automatic PCB cutting equipment. Background Art

[0002] PCB circuit board, also known as printed circuit board, is the basis of electronic equipment and is used to support and connect electronic components to realize the functions of the circuit. PCB circuit boards need to be cut during production and processing, and they need to be fixed during cutting. Traditional PCB cutting uses manual fixing and cutting. Manual fixing leads to poor cutting accuracy, resulting in low quality of PCB circuit boards after cutting, and manual fixing and cutting are prone to danger.

[0003] A Chinese patent discloses a PCB circuit board cutting machine (authorization announcement number CN211333348U). This patented technology provides a scale bar on the placement plate. According to the length of the PCB circuit board that needs to be cut in practice, the position of the PCB circuit board on the placement plate is adjusted to improve the accuracy of PCB circuit board cutting and the quality of PCB circuit board cutting. A nut, a threaded rod, a bearing, a rotating wheel and a clamping plate are provided. The nut is driven to rotate by rotating the rotating wheel, and then the threaded rod is driven to move up and down. The PCB circuit board is clamped by the clamping plate to avoid the danger caused by manual fixing of the PCB circuit board.

[0004] However, it has certain disadvantages: it can only clamp the PCB board in the vertical direction, the clamping direction is relatively single, and it uses a threaded rod to drive the clamping plate down for clamping. The PCB board will vibrate during cutting, and the vibration is transmitted to the threaded rod, causing it to vibrate. The threaded rod will rotate due to the vibration, causing the clamping plate to loosen its grip on the PCB board. Utility Model Content
