Description

Technical Field

[0001] The present application relates to the field of PCBA processing technology, and specifically to a cutting mechanism used for PCBA processing and production. Background Art

[0002] A PCBA is a printed circuit board (PCB) with electronic components already installed. It consists of a blank printed circuit board (PCB) and the various electronic components soldered onto it. However, when the PCB is cut during production, debris is generated. If the dust from the cutting process is not promptly handled, it can be inhaled, causing respiratory irritation and serious harm to the body.

[0003] In the patent number CN219543334U, a fixing device is provided on the placement plate to fix the PCBA and increase its firmness. The driving motor drives the threaded rod to rotate, so that the cutting device can perform mobile cutting. The movable seat is connected by the connecting strip to increase the firmness, so that the cutting knife can accurately cut the PCBA.

[0004] Although the above-mentioned prior art can perform mobile cutting, debris and dust are generated during cutting. If the debris and dust generated during cutting are not handled in time, they will be inhaled by the human body, causing respiratory irritation and great harm to the human body. They will also cause pollution or damage to dust-sensitive components on the PCBA. Therefore, a cutting mechanism for PCBA processing and production is proposed. Utility Model Content
