The invention relates to the technical field of optical control, and discloses a laser multi-beam etching control method, device and equipment for pole piece lineation, and the method comprises the steps: obtaining an etching specification and an etching material, and determining the installation position of a lens group based on a preset laser conduction length, an etching length and an etching path; controlling the light path system to position each transflective lens according to the mounting position of the lens group, correspondingly arranging a collimation focusing group on the lower side of each transflective lens, and determining the etching speed of a focusing head in each collimation focusing group based on the etching depth and width and the material etching attribute corresponding to the etching material, each focusing head is controlled to etch the target material according to the corresponding etching speed, non-contact processing can be provided, the etching line width is small, meanwhile, the high stability and accuracy are guaranteed, a large-breadth pole piece product is compatible, the processing breadth and the pole piece lineation width are not limited by a focusing field lens any more, and the production efficiency is improved. The production efficiency is ensured; and meanwhile, the cost and the later maintenance cost are reduced.
