[0002] IC chips are the core components of electronic products, so the accuracy, clarity and speed of mass production of their markings are particularly important. Automatic laser marking machines use advanced laser technology to quickly print various markings on the surface of IC chips, including serial numbers, production dates, manufacturer logos, etc. The laser is the core component of the automatic laser marking machine. The high-energy laser beam it generates is focused on the surface of the IC chip through the optical path system, causing the chip surface to instantly melt, vaporize or achieve other physical and chemical reactions, thereby forming a mark on the chip surface. The mechanical system is used to accurately control the position and movement trajectory of the laser beam to achieve batch marking of IC chips.

[0003] With the development of science and technology, the demand for chips in various electronic products in life is increasing. The traditional manual or semi-automatic marking methods can no longer meet the production needs of modern industry. The existing automatic marking machines generally directly transport the chips to the bottom of the marking machine for marking, resulting in various marks on the surface of the marked chips being tilted or unclear, resulting in the need for rework later, which consumes a lot of time and increases workload and labor costs. Therefore, it needs to be improved. Summary of the invention
