Description

Multi-station welding feeding device Technical Field The invention relates to the technical field of feeding equipment, in particular to a feeding device for multi-station welding. Background In the current industrial production, the multi-station welding process can continuously and efficiently complete complex welding tasks, and is widely applied to the manufacture of products such as heavy structural parts, automobile parts, frame structures and the like. Such processes typically require loading the workpiece onto a carrier platform of an initial station, and then sequentially moving the workpiece-loading carrier platform between stations according to a pre-arranged ground track, thereby sequentially completing different welding processes. In the loading stage, the traditional loading mode is to carry the workpiece positioned in the tray to an initial station through manual loading, and then manually install the workpiece on the carrier platform. To improve the above problems, partially automated feeding devices have been developed in the prior art. A typical solution is to provide a vertically lifting gripping disk above the carrier platform, through which the workpiece is directly lowered onto the carrier platform. Compared with a fully-automatic feeding mechanical arm, the scheme has lower cost. However, during actual use, this solution still suffers from the significant disadvantage of lacking an intermediate transition assembly for transferring the workpieces from the floor tray to the catch tray. The workpiece still needs to be manually placed below the grabbing disc, so that the feeding efficiency of the feeding mode is still limited. Disclosure of Invention The invention aims to provide a feeding device for multi-station welding, which solves the technical problem that in the prior art, a workpiece is still required to be manually and seriously fed due to the lack of a transition component for transferring the workpiece from a tray to a grabbing tray. In order to solve the technical problems, the invention specifically provides the following technical scheme that: The feeding line body is used for horizontally conveying and outputting the workpiece; The material receiving plate is arranged at the tail end of the feeding line body in a sliding manner, the top surface of the material receiving plate is flush with the top surface of the feeding line body and is used for receiving the end part of an output workpiece, and the material receiving plate is configured to slide along the direction away from the feeding line body so as to pull the other end part of the workpiece to drop vertically after being separated from the feeding line body; the bearing piece is correspondingly arranged below the tail end of the feeding line body along the vertical direction and is used for bearing the falling workpiece, and the bearing piece can slide to a to-be-fed area above the carrier platform; The grabbing disc is longitudinally and telescopically arranged above the to-be-loaded area and used for grabbing the workpiece on the supporting piece, and after the supporting piece slides away from the to-be-loaded area, the workpiece is downwards moved and placed on the carrier platform. As a preferable scheme of the invention, the material receiving plate is arranged on a mounting plate, and the mounting plate is arranged at the tail end of the material feeding line body in a sliding way; the receiving plate is retractably arranged on the mounting plate so as to release the support of the end part of the workpiece.
