LASER LABELLING APPARATUS Russian patent published in 2012 - IPC G02B26/08 B44B3/00 

FIELD: physics.

SUBSTANCE: apparatus has, arranged in series on the beam path and optically connected, a laser, a collimator, an acoustooptic and a piezoceramic deflector, a lens, a coordinate table, as well as a computer. The lens is directed onto the labelled article. The coordinate table consists of a movable part and a drive. One of the computer inputs is the input of the apparatus. The other inputs are connected to outputs of the piezoceramic deflector and the drive of the coordinate table, and the outputs are connected to inputs of the acoustooptic and piezoceramic deflectors and the coordinate table. An electromagnetic deflector is placed between the piezoceramic deflector and the lens. The input and output of the electromagnetic deflector are connected to the corresponding input and output of the computer. A box with labelled articles is mounted on the movable part of the coordinate table. The articles lie in the focal plane of the lens. The box has a depression whose dimensions match those of the labelled articles.

EFFECT: high efficiency of the laser labelling apparatus and shorter time for placing the articles into the working area.
