20140014702 | CARRYING APPARATUS AND CARRYING METHOD FOR BATTERY ELECTRODE MEMEBER - A carrying apparatus carries a battery electrode member (an electrode material film web or an electrode film). The carrying apparatus includes a carrier for holding while curving, and then carrying the electrode member. The carrier is configured to hold the electrode member at a position that doesn't cause a contact with components for another process at a downstream along a carrying direction. Since the electrode member is curved, its stiffness along the carrying direction is strengthened and thereby sagging down is prevented. In addition, the holding position by the carrier is the position that doesn't cause a contact with components for another process at a downstream along a carrying direction. Therefore, according to the carrying apparatus, it is possible to carry the electrode member (an end of an electrode material web or an electrode) to a target position reliably. | 01-16-2014 |

20140020238 | PRODUCTION DEVICE FOR PACKAGED ELECTRODE AND MANUFACTURING METHOD OF PACKAGED ELECTRODE - A production device | 01-23-2014 |
20140020239 | STACKING APPARATUS AND STACKING METHOD - The stacking apparatus of the present invention includes a separator conveyance unit to convey a separator of predetermined shape in a held state, an electrode conveyance unit to convey a positive electrode of predetermined shape, and a control unit to synchronize the conveying position and conveyance speed of the separator conveyance unit with those of the electrode conveyance unit so that the separator and positive electrode overlap each other at a predetermined position. The stacking apparatus conveys the separator and positive electrode and transfers the separator onto the electrode from a downstream side of the conveying direction while gradually removing the separator from the separator conveyance unit, thereby stacking the separator on the electrode. | 01-23-2014 |
20140020240 | BATTERY ELECTRODE MANUFACTURING APPARATUS AND METHOD THEREOF - A battery electrode manufacturing apparatus including: a front end die which cuts a strip-shaped electrode material into an electrode shape; a hand which grasps the electrode material and conveys the electrode material to the cutting position of the front end die; and a first suction conveyor which is disposed upstream of the front end die in a conveying direction and has a supporting surface for supporting the electrode material during the cutting by the front end die. The hand includes a first grasper and a second grasper, and the first suction conveyor is disposed between the first grasper and the second grasper. The hand carries the electrode material to the cutting position, at such a position that the electrode material does not contact the front end die and the first suction conveyor. | 01-23-2014 |
20140026398 | STACKING DEVICE AND STACKING METHOD - A first holding unit ( | 01-30-2014 |
20140026399 | STACKING APPARATUS AND STACKING METHOD - A stacking apparatus having a cylindrical conveyance drum holding and rotating to covey a separator and an electrode conveyance unit conveying a positive electrode in a tangential direction of the conveyance drum so that the positive electrode overlaps the separator. To the outer circumferential surface of the conveyance drum, there are defined a suction area for drawing the separator that is non-rotatably positioned on an upstream side of a rotation direction of the conveyance drum with respect to a location to which the positive electrode in conveyed and a non-suction area for removing the separator that is non-rotatably positioned on a downstream side of the rotation direction of the same. The separator in the suction area is conveyed to the non-suction area, is removed from the outer circumferential surface, and is transferred onto the positive electrode, thereby gradually stacking the separator on the positive electrode. | 01-30-2014 |
20140026400 | DEVICE FOR PRODUCING AND METHOD FOR PRODUCING PACKAGED ELECTRODE - A device for producing a packaged electrode includes: a pair of cylindrical rotating bodies arranged with their respective outer peripheral surfaces facing each other, and each configured to convey a separator by rotating while holding the separator on the outer peripheral surface; an electrode conveyance section configured to convey an electrode having a predetermined shape in a direction tangential to the cylindrical rotating bodies toward a gap between the cylindrical rotating bodies; and a joining section which joins the separators together, with the electrode sandwiched between the separators conveyed by the cylindrical rotating bodies. Also, the electrode is packaged with the separators by simultaneously delivering and laminating the separators from the rotating cylindrical rotating bodies to both surfaces of the electrode being conveyed by the electrode conveyance section, and joining together the separators delivered to both surfaces of the electrode by means of the joining section. | 01-30-2014 |
20140027067 | LAMINATION APPARATUS AND LAMINATION METHOD - A lamination, apparatus laminates sheet members including at least one of an electrode and a separator. The lamination apparatus includes a table on which the sheet members are laminated, a clamper that presses an assembled laminate of the sheet members laminated on the table; a clamper drive unit that horizontally-rotates and vertically-moves the clamper, a level adjuster that moves the table downward relative to the clamper according to a lamination progress of the sheet members. After a new sheet member is laminated on the assembled laminate pressed downward by the clamper, the clamper drive unit lifts up the clamper above the new sheet member while rotating the clamper and then moves the clamper downward to press the new sheet member from above. The level adjuster moves the table downward by a stroke corresponding to thickness of the number of laminated sheets of the sheet members included in the assembled laminate. | 01-30-2014 |
