A laminating device is adapted to laminate a plurality of sheet members on a lamination stage and includes: a plurality of laminating heads 2 that each has a curved holding surface; a drum section in which the plurality of laminating heads are arranged, the drum section holding each laminating head, and rotation of the drum section causing each laminating head to advance to a laminating position facing a planar lamination surface; and a rolling motion mechanism that rolls the holding surface on the lamination surface so that a delivery point of the sheet member moves from a rear end to a front end of the sheet member while each laminating head is caused to move by the drum section.

Provided are a roller assembly, a battery cell manufacturing device, and an adjustment method of a roller, which relates to the field of battery manufacturing technology. The roller assembly includes a holder, a roller, and a first adjusting member. The roller is rotatably mounted on the holder. The first adjusting member is rotatably mounted on the holder, and one end of the roller is rotatably connected to the first adjusting member. A rotation axis of the roller does not coincide with a rotation axis of the first adjusting member. One end of the roller is rotatably mounted on the holder through the first adjusting member. The rotation axis of the first adjusting member does not coincide with the rotation axis of the roller, and therefore, rotation of the first adjusting member is capable of driving a corresponding end of the roller to rotate, thereby adjusting an extension direction of the roller.

The disclosure provides a strap pulling device, the strap pulling device comprises a cutter mechanism, a first strap pulling mechanism and a second strap pulling mechanism. The first strap pulling mechanism and the second strap pulling mechanism are configured to alternately clamp a strap at a pulling position located upstream of a cutting position and pull the strap to a transfer position located downstream the cutting position. When the first strap pulling mechanism pulls the clamped strap to the transfer position, the second strap pulling mechanism clamps the strap at the pulling position, the cutter mechanism cuts the strap at the cutting position to acquire a strap segment. When the second strap pulling mechanism pulls the clamped strap to the transfer position, the first strap pulling mechanism clamps the strap at the pulling position, the cutter mechanism cuts the strap at the cutting position to acquire a strap segment.

According to an embodiment, a winding device includes a core, a transfer path, a pinch roller, a detection unit, a driving unit, and a control unit. A band body is wound around the core. The transfer path transfers the band body to the core. The pinch roller presses the band body being transferred in the transfer path from one side of a first direction intersecting a transfer direction, and presses a partial range of the band body in a second direction intersecting both the transfer direction and the first direction. The detection unit detects an abnormally shaped portion formed in the band body in the transfer path. The control unit controls the driving unit based on a result of detection by the detection unit.

An automatic replacement apparatus for a feed material includes a discharge unit discharging a feed material to the outside, a pair of feed units disposed to be adjacent to the discharge unit and having a feed roll around which the feed material is wound, and a pair of material joint units respectively provided in the pair of feed units connecting a front end of a first feed material waiting in a first feed unit, one of the pair of feed units, and an end of a second feed material being transferred from a second feed unit, the other of the pair of feed units, to the discharge unit in a butt joint manner.

A jig configured to support an electrode which is transported along a first direction, in which the electrode includes a coated portion coated with an electrode active material and an uncoated portion not coated with the electrode active material, includes a first support portion configured to support an area corresponding to the uncoated portion of the electrode, the first support portion including a laser receiving portion at a location corresponding to an irradiation area of a laser for cutting the uncoated portion; and a second support portion configured to support an area corresponding to the coated portion of the electrode.

A placement method using a placement device provided with a first process of pressing a transfer plate a topmost layer sheet member so as to pick up it when a restraint device is rendered a restraining state, a second process of rendering the restraint device a non-restraining state to render the transfer plate an inclined state while pressing down the plurality of sheet members from above in the stacking direction by a base end part side of the transfer plate rendered the inclined state, a third process of inserting the restraining blade into the space formed between the topmost layer sheet member and the sheet member of the layer below it and again render the restraint device the restraining state, and a fourth process of making the transfer plate retract upward while returning it to the horizontal state and transferring the topmost layer sheet member to the holder.

A sheet material conveyance device includes a plurality of first holding heads each having a curved first holding surface, a first drum holding the plurality of first holding heads, a plurality of second holding heads each having a planar second holding surface, a second drum holding the plurality of second holding heads, a tilt adjustment mechanism structured to adjust a tilt of each second holding surface, and a speed adjustment mechanism structured to adjust a relative movement speed of the first holding head and the second holding head. The first holding head and the second holding head move to a delivery position, and deliver the sheet material between the first holding surface and the second holding surface in a situation in which adjustment is performed by the tilt adjustment mechanism and the speed adjustment mechanism.

A device for manufacturing a laminated electrode comprises: a negative electrode cutting drum that forms a negative electrode sheet by cutting a negative electrode single sheet to a first width and conveys the negative electrode sheet; a negative electrode heating drum that heats the negative electrode sheet; a positive electrode cutting drum that forms a positive electrode sheet by cutting a positive electrode single sheet to a second width and conveys the positive electrode sheet; a positive electrode heating drum that heats the positive electrode sheet; and a bonding drum at which the negative electrode sheet is arranged on a first separator single sheet, a second separator single sheet is arranged on the negative electrode sheet, the positive electrode sheet is arranged on the second separator single sheet, and the sheets are bonded. The negative and positive electrode cutting drums include: a plurality of holding heads and pairs of blades.
