Abstract: A roof laser brazing system comprises a side home position jig installed at each of opposite sides of the transferring path of the body in the brazing section, a roof-pressing jig detachably mounted on a handling robot, docked to the side home position jig, and that home-positions and presses the roof panel loaded on the opposite side panels, a brazing assembly mounted on at least one brazing robot in the side home position jig side and that brazes bonding portions between the opposite side panels and the roof panel using a laser as a heat source, and a grinding assembly mounted on the at least one grinding robot in the grinding section and that grinds brazing beads of the bonding portions between the opposite side panels and the roof panel.

Abstract: A jig apparatus is used for assembling a trunk lid including an upper panel, an extension panel, and a lower panel. The jig apparatus may include: a jig frame; a first activation jig unit configured to align and fix the upper panel and the extension panel and installed at the jig frame in front and rear directions to be tilting-rotatable; and a second activation jig unit aligning and fixing the lower panel and installed at the jig frame to be linearly movable in the front and rear directions with respect to the first activation jig unit.

Abstract: An attachment apparatus for a vehicle body includes: a first roller rotatably disposed at a first hinge at one side of upper portion of a moving body and moving up and down with respect to a first fixing body; a link rotatably disposed with reference to the first hinge and extending to both directions; a second roller rotatably disposed at a second hinge at one end portion of the link and disposed at one side of the first roller; and a first elastic member disposed to elastically pull or push another end portion of the link so that the second hinge rotates with reference to the first hinge, wherein the first and second rollers respectively contact with a surface of the vehicle body.
