Size control method and device for box dam packaging and electronic equipment

The embodiment of the invention discloses a size control method and device for box dam packaging and electronic equipment. The method comprises the following steps: acquiring a real-time printing image of a target box dam structure, and constructing a soft measurement model based on the real-time printing image; determining a current printing position of the target box dam structure in the soft measurement model, and determining real-time size data of the current printing position on a current printing layer; and determining standard size data corresponding to the current printing layer, generating printing correction data based on a difference value between the real-time size data and the standard size data, and adjusting current printing data of the box dam printing head based on the printing correction data. According to the embodiment of the invention, the soft measurement model can be constructed to determine the real-time size data of the target box dam structure at the current printing position, so tha
