Abstract

[0002] In the current PCB board depaneling and cutting field, there are many problems that urgently need to be solved. Traditional cutting methods, due to the lack of precise cutting control, often result in cutting position deviations during the cutting process. This leads to the PCB boards being unable to meet the increasingly demanding process requirements, greatly affecting product quality and production efficiency.
[0003] Previous devices for workpiece positioning lacked flexibility. Adjusting the workpiece to a suitable cutting position was inconvenient and had limited positioning accuracy. Once cutting was complete, repositioning the workpiece was extremely difficult, making it hard to guarantee high precision for subsequent cuts and resulting in an inefficient and less smooth production process.
[0004] In addition, traditional measurement methods are often not accurate enough in terms of measuring the cutting position, and they lack an effective mechanism for quick locking and repeated measurement. A lot of time needs to be spent on position measurement and calibration before each cut, which undoubtedly seriously affects work efficiency, increases production costs, and makes it difficult to adapt to the fast-paced needs of modern industrial production.
