[0002] Automatic plug-in equipment, commonly known as automatic insertion machine or automatic chip insertion machine, is a machine used to automatically insert electronic parts onto printed circuit boards (PCBs). Such equipment is widely used in the electronics manufacturing industry, including consumer electronics, communication equipment, automotive electronics, medical equipment and other fields. It plays a vital role in the modern electronic manufacturing process. They can complete complex plug-in tasks with high precision and high speed, thereby greatly improving production efficiency and product quality.
