Feeding and discharging treatment method and device and feeding and discharging system

The invention discloses a feeding and discharging treatment method and device and a feeding and discharging system. The method comprises the steps that label information of multiple to-be-fed productsis read through scanning equipment; based on the label information, production information of the multiple to-be-fed products is acquired from an MES system, and the production information comprisesproduction batches of the multiple to-be-fed products and production requirements; according to the production information of the multiple to-be-fed products, it is confirmed that the multiple to-be-fed products and products already fed in the last feeding stage belong to the same batch; and a feeding grabbing signal is sent to a robot through a programmable logic controller (PLC) so as to triggervisual inspection equipment of the robot to collect images of the to-be-fed products, and feeding is carried out based on the image analysis result. The technical problems that in the correlation technique, manual parameters a
