[0001] The utility model relates to the field of chip placement machines, and more specifically, to an impact-proof chip placement machine nozzle structure. Background Art

[0002] As the name suggests, a placement machine nozzle is a tool used to pick up and place SMT components on a placement machine. There are a wide variety of nozzle types and materials available on the market. In the current surface mount process, the placement machine uses a nozzle at the end of its placement head to remove various components from a component tray or tray and place them in the correct position on the printed circuit board (PCB).

[0003] Existing nozzles for placement machines have some defects during use. For example, the nozzles are subject to certain impacts when picking up components, and are also subject to certain impacts during the placement process, making the nozzles easily damaged and reducing their service life.

[0004] Therefore, in order to solve the above problems, an anti-impact placement machine nozzle structure is proposed. Utility Model Content
