The role of the placement machine nozzle

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

When the mouthpiece of the SMT machine absorbs the component, in order to achieve the ideal situation, it is necessary to ensure that the center of the component, the center of the mouthpiece and the spatial center of the obtained image should be coincident, and the adjustment of the optical vision system is actually to compensate for the deviation caused by this non-coincidence in the actual work.

Different mount components require different suction nozzles. Almost every nozzle has a reflective background, which is mainly to have a good background when the image is taken, so as to ensure the accurate prominence of the target information during image processing. When the image is extracted, the nozzle is used as the background to enhance the image contrast of the component and make it more clearly visible.
