Abstract

The invention discloses pole piece and isolating membrane thermal compounding equipment, which comprises at least two sets of preheating mechanisms, a hot rolling mechanism, a connecting rod tensioning mechanism, a shaping roller, a magnetic strip, a dust collection cavity and a material receiving roll. The preheating mechanisms are sequentially arranged on the side wall of a rack in parallel at intervals. The hot rolling mechanism is arranged at the side part of the preheating mechanism. The connecting rod tensioning mechanism is arranged at the side part of the hot rolling mechanism. The film-coated pole piece is tensioned by the connecting rod tensioning mechanism. The shaping roller, the magnetic strip and the dust collection cavity are sequentially arranged at intervals, and when thefilm-coated pole piece sequentially penetrates through the shaping roller, the magnetic strip and the dust collection cavity, shaping is conducted to magnetically adsorb metal on the surface of the pole piece and remove dust on the surface of the pole piece. The number of the material receiving rolls is two, the two material receiving rolls are arranged up and down at an interval, and the end parts of the protective films on the surfaces of the isolating films on the upper surface and the lower surface of the film-coated pole piece are connected to the material receiving rolls. Automatic preheating, hot rolling compounding, automatic tensioning, pole piece surface metal and dust removal and automatic protection film winding functions of the pole piece and the isolation film are achieved.

Description

technical field [0001] The invention relates to the field of lithium batteries, in particular to thermal compound equipment for pole pieces and separators. Background technique [0002] Currently, global lithium battery companies are mainly concentrated in South Korea, China and Japan. Japan monopolized the global lithium battery industry before the 21st century, and its main product is secondary lithium batteries. Later, with the research and development of lithium battery production technology in South Korea and China, it gradually occupied a certain market in the world. Famous lithium battery manufacturers abroad include Sanyo, Bosch, Samsung, Panasonic, Sony, Toyota, Toshiba, Ford, GM, Mercedes-Benz, etc. These manufacturers generally have a complete set of lithium battery production lines, including lithium battery winding equipment and tab welding equipment, which are generally provided by specialized equipment manufacturers. According to survey statistics, the scal...
