Abstract:
1. A device for assembling a vehicle body in order to assemble a dash panel to a left side member and a right side member comprises: at least three sets of locate units that are disposed at both sides of a base plate, hold side members through a clamping pin inserted into a tooling hole formed at a lower portion of the side members, and control the side members to move in four directions or a vertical direction by three servo motors; a robot hanger unit disposed at the front end of an arm of a handling robot disposed at the front side of the base plate in order to load the dash panel between the side members held by the locate unit in a state in which the clamping pin is inserted into a tooling hole formed at a surface of the dash panel, and at the same time to transport the side members and the dash panel assembly to a parts unloading process; a parts loading robot respectively disposed at both sides of rearward of the base plate so as to clamp the left/right side members, and to load the side members to the locate unit; and a welding robot integrally provided with a spot welding gun at the front end thereof and disposed at both sides of the base plate so as to weld abutments of the side members and the dash panel, wherein the locate unit comprises: a main plate mounted at one side of the base plate; a longitudinal rail mounted at the main plate in a longitudinal direction a longitudinal rail block slidably mounted at the longitudinal rail; a longitudinal drive member connected to the longitudinal rail block in a state of being arranged on the main plate along one side of the longitudinal rail so as to slidably move the longitudinal rail block along the longitudinal rail using a rotating force; a rail plate mounted on an upper surface of the longitudinal rail block; a traverse rail traversely mounted on the rail plate; a traverse rail bock slidably mounted at the traverse rail; a traverse drive member connected to the traverse rail block in a state of being arranged on the rail plate along one side of the traverse rail so as to slidably move the traverse rail block along the traverse rail by using the rotating force; a slide guider perpendicularly mounted at an upper surface of the traverse rail block; a vertical slider slidably mounted on the slide guider so as to be moved upward and downward; a vertical drive member connected to the vertical slider in a state of being arranged perpendicularly on the traverse rail block along one side of the slide guider so as to slidably move the vertical slider along the slide guider by using the rotating force; and a pin clamping member disposed at an upper end of the vertical slider so as to hold the parts by using air pressure in a state in which a clamping pin is inserted into the tooling hole.
