Abstract
The present specification relates to an embodiment of an electrode material winding apparatus, in which an electrode material is processed so that an electrode tab is not disposed in an impregnation region into which an electrolyte can be injected, and the electrode material is wound so that the electrode tab is arranged only in a specific region excluding the impregnation region, thereby winding the electrode material such that the electrolyte is injected through the impregnation region.
Claims20
An electrode material winding apparatus that winds an electrode material, the apparatus comprising:
- a processing unit that processes at least one end portion of upper and lower ends of the electrode material so as to allow an electrode tab connected to an electrode plate to be formed in a predetermined pattern at the end portion;
- a winding unit that winds the electrode material into a cylindrical jelly roll;
- a guide unit that comes into contact with a winding surface on which the electrode material is wound to apply a pressure to the winding surface so as to allow the electrode tab to be arranged in a specific region corresponding to a part of at least one cross section of upper and lower surfaces of the jelly roll;
- a detection unit that detects an input length of the electrode material introduced at a front end of the winding unit;
- and
- a control unit that determines an arrangement state of the electrode tab based on a result of the detection by the detection unit, and controls a position of the guide unit according to a result of the determination to adjust the pressure.
