Description

Anti-blocking device for suction nozzle of SMT chip mounter Technical Field The utility model relates to the technical field of suction nozzles of chip mounters, in particular to an anti-blocking device for a suction nozzle of an SMT chip mounter. Background In the SMT field of electronic manufacturing, the cleanliness of a suction nozzle of a chip mounter directly influences the accuracy and quality of a chip, a traditional suction nozzle depends on manual disassembly and cleaning, interface abrasion is easily caused by frequent disassembly, the service life of the suction nozzle is shortened, the manual cleaning is difficult to touch an internal microstructure, and residual pollutants such as soldering paste, metal chips and the like easily cause component adsorption deflection or block a negative pressure hole, weaken adsorption force, cause defects such as chip deflection, tombstoning and the like, influence welding reliability and are difficult to meet high-precision mounting requirements; The patent with the publication number of CN218499515U rotates through the scraper to scrape the impurity, the frequent dismantlement wearing and tearing problem has been avoided, but the clean mode has obvious limitation, simple scratch can only peel off the impurity, can't discharge it inside the suction nozzle, viscidity or liquid pollutant are more difficult to clear away, remain the impurity still has the jam risk, and simultaneously, this structure does not integrate the washing function, be difficult to deal with complicated pollution scene, and when clean part ages and damages, need whole dismantles the maintenance, the step is loaded down with trivial details, probably destroy equipment seal, influence stability, along with the electronic components develop to miniaturization, high density subsides, the defect of current suction nozzle cleaning technique is more prominent, frequent shut down clean reduces production efficiency, suction nozzle wearing and consumption push up the maintenance cost, clean incompletely still probably causes batch quality defect, it has certain defect and not enough, consequently, need carry out improvement design to it.
