What should I do when throwing materials with a surface mount machine

SMT is a surface mount system, in which the main machine is the surface mount machine, which is used to mount various components onto PCB pads. We have noticed a phenomenon when using the surface mount machine, which is the phenomenon of material throwing. As a result, we generate a lot of waste. So, how should we solve this problem. Now let's search and troubleshoot the problem. Fault 1: Detecting the nozzle When using the surface mount machine, the nozzle may deform, break, leak, and other phenomena due to various reasons. If the nozzle is not replaced in a timely manner, it will cause difficulties in material suction and improper material retrieval. Therefore, we should regularly check and replace the nozzle. Fault 2: Setting problem. When using the surface mount machine, we must calibrate the positioning system to check whether the material retrieval is in the center. If there are problems such as incorrect retrieval height and deviation, the surface mount machine will treat these as indistinguishable garbage, resulting in material throwing. Therefore, we should develop a good habit of calibrating the retrieval direction before operation. Fault 3: Air Pollution Our surface mount machines are often placed in factory workshops, and in the workshop, dust in the air will fall on the surface mount machines. If there is dirt on our laser lenses, it will interfere with the system and cause high material rejection rates. We need to regularly clean the surface mount machine. If the identification system is already broken, we need to consider replacing it with a new identification system component.
