  • Publication number: 20250038243
    Abstract: A taping device for a stacked electrode assembly includes a support part, a vacuum adsorption part, a gripper part, and a taping mechanism part. The support part corresponds to the central portion of the tape to be attached to the stacked electrode assembly and the lateral side of the stacked electrode assembly. The vacuum adsorption part adsorbs and fixes the non-pressure-sensitive adhesive side of the tape. The gripper part further fixes the tape by operating to grip the end of the tape and the taping mechanism part attaches the tape to the upper surface and the lower surface of the stacked electrode assembly by moving along the upper surface and the lower surface of the stacked electrode assembly from the upper portion and the lower portion of the support part. A method including the same is also provided.

  • Patent number: 10806992
    Abstract: Provided is a game device which can be used for education, play or the like, in which, when three or more chips having the same colors or shapes are placed in a column by allowing a player to insert the chips having at least two types of colors or shapes into input holes (slots) formed at the upper parts of each column, a game is won. This device may have a shape enabling the game to be played by using one surface and at least two surfaces while rotating a body if necessary, and to a shape enabling the game to be played by further using an upper surface. This device can have a structure enabling a game to be played by placing the chips on the outer surfaces of a cube, and enabling various games to be played by allowing space division to be clarified.
