Abstract

The invention provides a robot welding control system and control method based on a PLC. The system comprises a robot body, a servo system of the robot body, a welding device, a visual sensing deviceand a control center, and the control center takes the PLC as a main controller; the visual sensing device generates and collects laser stripes projected to the surface of a welding workpiece and transmits the obtained groove information of the welding workpiece to the PLC, and the PLC plans a welding bead based on the groove information and conducts welding control; and the robot servo system comprises a program processing unit and a communication unit, and the PLC calls the program processing unit through the communication unit to control work of the welding device, the visual sensing deviceand the robot body. The coordination of the welding system device, the robot system, external equipment and the visual sensing device can be effectively promoted through the strategies of visual acquisition, PLC operation transmission, robot execution and external equipment assistance, welding in the whole process is automatically achieved, and the welding quality and the welding efficiency during multi-layer and multi-pass welding can be ensured.

Description

technical field [0001] The invention relates to the technical field of robot welding, in particular to a PLC-based robot welding control system and control method. Background technique [0002] With the development of heavy industry, there is an increasing demand for ultra-thick plate welding in domestic and foreign manufacturing fields. When welding large ultra-thick plates, due to the large depth of the groove and the wide opening, it is necessary to use multi-layer and multi-pass welding methods to obtain the best welding effect. In traditional multi-layer and multi-pass welding applications, manual welding is mostly used, which has low welding efficiency and high labor intensity. It is the general trend to use robots instead of manual to realize multi-layer and multi-pass automatic welding. [0003] At present, when robots are used for multi-layer and multi-pass welding of ultra-thick plates, predetermined rules are usually used for welding. Due to the deep groove, the...
