System and method for constructing a metal grid frame

Abstract

The invention discloses a metal net frame building system. The system comprises a conveying unit capable of conveying metal rods, a robot building clamping and positioning unit capable of clamping themetal rods, a robot welding unit capable of welding the metal rods, a bottom disc unit capable of bearing the metal rods and a control unit; and the conveying unit, the robot building clamping and positioning unit and the robot welding unit are all in signal connection with the control unit. The invention further provides a metal net frame building method. The method comprises the steps that an operator obtains a meshing model through the control unit, then the movement paths of the robot building clamping and positioning unit and the robot welding unit are generated; and the control unit controls the robot building clamping and positioning unit to clamp the metal rods and then position the metal rods according to the movement path, and the control unit continuously controls the robot welding unit to weld the metal rods according to the preset movement path. The problem that a component with a non-right-angle relation is large in positioning error is solved, and the welding forming precision and efficiency of the metal net frame building are improved.

Description

technical field [0001] The invention relates to the technical field of metal grid construction, in particular to a metal grid construction system and method. Background technique [0002] The metal grid frame is a space structure formed by connecting multiple metal rods through nodes according to a certain grid form. The grid frame has the advantages of space force, light weight, high rigidity, and good seismic performance. The disadvantage is that it meets at the nodes The number of rods on the surface is large, and the production and installation are more complicated than the plane structure, which often requires the use of rapid prototyping technology and metal welding technology. The main principle of the current rapid prototyping technology is to slice the three-dimensional data model in the computer to obtain the contour data of the interface of each layer. According to this information, the computer controls the laser (or nozzle) to selectively sinter the powder layer...

Problems solved by technology

The metal fusion welding technology in the existing construction industry can help the fixed formation between building construction and construction, but the existing fusion welding technology has the disadvantages of the forming and positioning of building construction: traditionally welded metal grids often become Cartesian coordinates, for non-linear and non-rectangular building construction, there are problems of difficult positioning and poor construction accuracy; traditional manual welding is not efficient and slow
