This invention relates to a chopsticks cleaning module, comprising a chopsticks basket; a piezoelectric
ceramic sheet disposed at the bottom of the basket; a magnetic component disposed at the bottom of the piezoelectric
ceramic sheet; an
information acquisition board electrically connected to the piezoelectric
ceramic sheet; chopsticks, with a
metal sheet at the
tail end sealed and capable of generating magnetic force with the magnetic component, and the
tail end face of the chopsticks also having a feature component for image recognition; an
image acquisition device disposed above the chopsticks basket; and a
robotic arm disposed on one side of the chopsticks basket. This chopsticks cleaning module can effectively detect the orientation of the chopsticks in the basket and thus adjust the orientation of the chopsticks to be consistent. This invention also relates to a chopsticks
placement method, which determines whether all chopsticks in the basket are correctly positioned based on weight data detected by the piezoelectric ceramic sheet, and adjusts incorrectly positioned chopsticks in the basket to the correct orientation based on the
image acquisition device and the
robotic arm. This invention also relates to a cleaning
machine using the chopsticks cleaning module and a storage medium.
