The invention relates to an electrode plate wrapping method, which comprises the steps of: first, arranging a positive electrode plate and a negative electrode plate in an electrode plate material box vertically respectively, above all using a sucking disc to suck the positive electrode plate laterally, then turning the positive electrode plate downward by 90 degrees and placing it in a material trough, moving the positive electrode plate placed in the material trough forward by one working position, at the same time moving separator paper from top to bottom, cutting the separator paper off and disposing it on the material trough vertically, further moving the positive electrode plate forward by one working position, and making the front end of the positive electrode plate contact the central part of the separator paper in the moving process, along with the forward moving of the positive electrode plate, wrapping the positive electrode plate with the separator paper, then further moving the positive electrode plate forward by one working position, simultaneously employing the sucking disc to suck a negative electrode plate laterally, and placing the negative electrode plate right over the wrapping completed positive electrode plate, then keeping moving the negative electrode plate, the separator paper, and the positive electrode plate forward into a material receiving device, and when the number of a plate pack is collected, sending the plate pack out.
