[0002] The grid is a spatial structure formed by connecting multiple rods through nodes in a certain grid form. According to the different shapes, the grid can be divided into: plate grid structure, single-layer grid structure, double-layer grid structure and shell grid structure. The grid has the advantages of good seismic performance, light weight and high rigidity, so it is widely used in large-spacing buildings such as stadiums and hangars.

When the utility model performs a grabbing operation on a steel pipe workpiece, the steel pipe upper and lower line controller compares the end face position information of the steel pipe workpiece fed back by the pattern recognition sensor with the end face position information of the built-in standard steel pipe workpiece, and calculates the offset, and then the steel pipe upper and lower line controller adjusts the position of the steel pipe upper and lower line grabbing and stacking mechanical arm according to the calculated offset, with a high degree of automation, and can accurately grab and stack the steel pipe workpiece without welded sealing plate or cone head workpiece on the welding work platform.

[0004] In the prior art, steel grid rods are automatically welded by robots during the conveying process through a conveying device.

The welding method requires queuing and welding one by one. This structure and welding method greatly reduce the welding efficiency of the steel grid rods. Therefore, it is necessary to realize an adjustable steel grid rod welding conveying device. Utility Model Content
