The mouthpiece of the placement machine is not only the key part of the placement machine to absorb components for attaching and placing action, but also the background of the camera of the optical vision system. It mainly uses the vacuum adsorption principle to absorb components, and uses blowing to put the components adsorbed in the mouthpiece on the coordinate position of the circuit board.

Different mouthpieces should be selected for different components. In order to have a good background when the image is taken, so that the target information can be successfully highlighted in the image processing, almost every nozzle has its reflection background, when the image is extracted, the nozzle is used as the background, so that the image contrast of the component is strong and clearer when the mouthpiece of the placement machine absorbs the component, in an ideal situation, the center of the component, the center of the mouthpiece and the space of the obtained image The heart should be overlapped, and the adjustment of the optical vision system is actually to compensate for the actual work

When people design the nozzle, taking into account the above nozzle function, people usually design the surface of the nozzle contact element into a center symmetrical shape, and the background plane of the nozzle as the background of the photo is designed into a matte surface and the surface is not mixed color, of course, the background is usually designed into a single color, such as black and green.
