Abstract

The invention relates to a flexible gripper for assembly and welding of a body-in-white top cover and a body-in-white top cover conveying system employing the flexible gripper for assembly and welding of the body-in-white top cover. The gripper comprises a rigid connecting frame, a movable connecting frame, a movable connecting unit, a locating unit, a movable locking unit and a grabbing unit, wherein the rigid connecting frame and the movable connecting frame are connected through the movable connecting unit; and the locating unit comprises a front cross beam locating mechanism and a top cover locating mechanism used for clamping and fixing the top cover to a body-in-white. According to the flexible gripper, when the movable connecting frame is in the locked state, the grabbing unit carries the top cover to the top of the body-in-white, the movable locking unit is unlocked, the top cover slides into a side wall guide groove, and the Y-direction assembly and welding requirement is met; a locating pin of the front cross beam locating mechanism is inserted into a front cross beam locating hole, and X-direction locating of the top cover is achieved; and the top cover locating mechanism acts, Z-direction locating of the top cover relative to a cross beam is achieved, and the assembly and welding precision requirement of the top cover is met.

Description

technical field [0001] The invention belongs to the technical field of body-in-white welding, and in particular relates to a flexible gripper for welding a body-in-white roof and a body-in-white roof conveying system using the flexible gripper for welding a body-in-white roof. Background technique [0002] In the field of body-in-white welding, looking at the existing body-in-white roof welding stations, the roof welding mostly adopts the robot with hard-connected gripper positioning method and the Perceptron visual positioning guidance system. The positioning method of the robot with hard-connected grippers cannot eliminate the repetitive error in the size of the body-in-white welding at the front station, and cannot guarantee the quality required for the weld seam gap of the roof laser welding in the next process; the Perceptron visual positioning guidance system is adopted The method is expensive and difficult to debug.
