Essential knowledge about the suction nozzles of surface mount technology (SMT) machines

The nozzle of a surface mount technology (SMT) placement machine is an indispensable key component. Its function is not only to pick up components for placement but also to serve as the background for the camera of the optical vision system when taking pictures.

The suction nozzle is the part that directly contacts the SMD component when vacuum negative pressure occurs. The size of the suction nozzle hole is related to the shape of the SMD component. Since the surface mount technology (SMT) placement machine is capable of mounting a wide variety of components, it is also necessary to be equipped with an automatic nozzle replacement device on the SMT placement machine. There is also an elastic compensation buffer mechanism between the suction nozzle and the suction pipe, ensuring that the suction nozzle protects the components during the process of picking up and placing them, and improving the mounting rate of the equipment.

In the market, there are quite a few materials for surface mount technology (SMT) machines to attach 觜. The most widely used ones include ceramic, tungsten steel, carbon fiber and composite materials, etc.

Surface mount technology (SMT) machine suction nozzle

The performance of the suction nozzle of the surface mount technology (SMT) machine mainly depends on the size of the suction 觜 and the degree of fit of the components being picked. It depends on the shape and size of the components. If it is for mounting special components, special-shaped suction nozzles can also be used for mounting production.

Although the surface mount technology (SMT) suction nozzle looks very small, it plays a significant role in SMT production. Therefore, when purchasing suction nozzles, there are some points to note. The prices of different materials and models of suction nozzles for surface mount technology (SMT) machines can vary greatly. Some chip component suction nozzles cost over a hundred yuan each, but some suction nozzles for irregular shapes may cost over a thousand yuan each. So now the counterfeits on the market are very cheap, and some can even reach a level that is indistinguishable from the real thing, but there is still a big difference when they are used. However, all purchases in this regard need to be reviewed by engineers. Experienced engineers can tell at a glance. The main issue still lies in the difference in materials.
