Pressure device, battery module manufacturing device, and manufacturing method

Discussed is a bolting device that effectively protects an internal configuration of a battery pack and increases manufacturing efficiency during a bolting operation. The bolting device for manufacturing a battery pack includes an electric screwdriver provided with a rotation motor; a driver bit connected to the rotation motor to enable a rotation movement and configured to rotate a bolt; a bit guide member provided with a hollow tube such that the driver bit is inserted into an inside of the hollow tube to be movable; and a guide jig provided with a main body configured to be mounted on an upper portion of a pack housing, the main body having a plate shape and having at least one through hole, and a fixing member inserted into the through hole and mounted therein, and having an insertion hole.

Bolting device for manufacturing battery pack

Discussed is a manufacturing apparatus including a robot arm, which may increase production efficiency and greatly reduce the size of manufacturing equipment. The manufacturing apparatus includes a robot arm to manufacture a battery module that includes a plurality of cylindrical battery cells and a module housing having an upper case and a lower case configured to accommodate the plurality of cylindrical battery cells. The robot arm includes a first gripper configured to hold or release the plurality of cylindrical battery cells; a second gripper configured to hold or release the upper case; and a third gripper configured to hold or release the lower case.

Robot comprising robot arm

Discussed is a battery pack manufacturing apparatus and method, and more particularly, a battery pack manufacturing apparatus allowing automatic production and having a minimized manufacturing defect rate. The battery pack manufacturing apparatus manufactures a battery pack having a pack housing and a battery module, and includes a lifting mechanism having a frame configured to mount the pack housing and a moving unit configured to move the frame so that the battery module is inserted into an inner space of the pack housing; and a module support configured to support the battery module.

Battery pack manufacturing apparatus and method, and battery pack

Disclosed is a battery module that reduces damage of internal components during an assembling process and enhances the manufacturing efficiency. The battery module includes a plurality of cylindrical battery cells arranged in a horizontal direction and each standing upright in a vertical direction; and a module housing including outer sidewalls configured to form an inner space, a plurality of hollow tubes having inner sidewalls located in the inner space and extending in the vertical direction to accommodate the plurality of cylindrical battery cells therein, and a cavity formed by opening at least a part of vertical central portions of the inner sidewalls of the plurality of hollow tubes to form an empty space therein.

Battery module including module housing

A method for manufacturing a battery module includes preparing a plurality of cylindrical battery cells having electrode terminals respectively at upper and lower portions, and a module housing having an accommodation portion with a plurality of hollow structures to accommodate the cylindrical battery cells therein; adding an adhesive having thermally and ultraviolet curing properties to an inner surface of the accommodation portion; partially curing the adhesive by applying heat thereto to increase a viscosity of the adhesive; accommodating the cylindrical battery cells in the accommodation portion so that the partially-cured adhesive is between the accommodation portion of the module housing and the cylindrical battery cells; after the accommodating of the cylindrical battery cells in the accommodation portion, applying heat to the adhesive to lower the viscosity of the adhesive; and, after the viscosity is lowered by applying the heat, curing the adhesive by irradiating ultraviolet rays to the adhesive.
