  • Patent number: 11090827
    Abstract: A cutting device includes a guide extending in a vertical direction, a cutting mechanism that includes a cutting blade and that moves in the vertical direction along the guide, a drive device that moves the cutting mechanism in a horizontal direction by moving the guide in the horizontal direction, a pressing device that presses the cutting mechanism from above, and a reception base on which a cutting object is placed and that receives the cutting blade during the cutting movement. During cutting of the cutting object, the cutting mechanism pressed by the pressing device is moved downward along the guide and cuts the cutting object placed on the reception base with the cutting blade.

  • Patent number: 11063301
    Abstract: A manufacturing apparatus creates an electrode laminate in which an electrode is sandwiched between first and second separators. A first sensor detects a first lateral positional displacement amount in a width direction of the first separator with respect to a predetermined reference position. An electrode supply unit supplies the electrode to a predetermined electrode supply position. A second sensor detects a second lateral positional displacement amount in a width direction of the second separator with respect to a predetermined reference position. A control unit corrects a position of the first separator based on the first lateral positional displacement amount and corrects a position of the second separator based on the second lateral positional displacement amount.

  • Patent number: 10991968
    Abstract: A conveying device includes a flat plate member including a through-hole and a first conveying head that sucks a conveyance object via the through-hole in a state of holding the flat plate member and conveys the flat plate member and the conveyance object to an accommodation case. Moreover, the flat plate member has a shape that prevents an end of the conveyance object from abutting an inner side surface of the accommodation case during placement into the accommodation case.

  • Patent number: 10985408
    Abstract: An electrode supply unit corrects an electrode target position based on a positional displacement amount of a first separator material, a first offset amount which is an actual positional displacement amount between the first separator material and an electrode when the first separator material is supplied in a manner that a positional displacement is not generated, and a movement amount in a lateral direction when an electrode supply region moves from a first position T1 to a second position T2 The electrode supply unit then supplies the electrode to the first separator material.

  • Publication number: 20200152944
    Abstract: A manufacturing device for manufacturing an electrode assembly by laminating unit electrode assemblies in each of which an electrode is placed on a separator. The device includes a transferring device that includes a sucking plate and transfers, onto the positional adjustment stage, each of the unit electrode assemblies sucked up by the sucking plate. Moreover, an image capturing device captures an image of the electrode of each of the unit electrode assemblies placed on the positional adjustment stage. A positional adjustment device positionally adjusts the positional adjustment stage based on the image of the electrode captured, and a transferring and laminating device picks up each unit electrode assembly and transfers each to a lamination stage and performs a lamination process. At least part of the sucking plate is transparent and the image capturing device captures an image of the electrode from above the transparent portion of the sucking plate.
