Control system of flexible welding robot for automobile body

Abstract

The invention discloses a control system of a flexible welding robot for an automobile body. The control system comprises a programmable logic controller (PLC), a display module, a key panel, a driving control module, a welding parameter detection module, a CAN communication module and an upper computer, wherein the PLC is connected with the display module, the key panel, the driving control module and the welding parameter detection control module and is also connected with a CAN communication bus through the CAN communication module, and the CAN communication bus is connected with the uppercomputer. The control system further comprises a wireless communication module, a watchdog module, a storage module and an alarm module, wherein the alarm module is connected with the PLC. According to the control system of the flexible welding robot, various communication modes are achieved, and thus, monitoring by workers is facilitated; a GPS positioning module is additionally arranged, so thatthe current position of the robot can be conveniently positioned; and moreover, the control system adopts the modular design, thereby being low in cost and convenient to develop and having good application prospects.

Description

technical field [0001] The invention belongs to the technical field of automobile production, and in particular relates to a control system of a flexible welding robot for automobile bodies. Background technique [0002] In an automobile factory, the welding production line is more rigid than the painting line and final assembly line, and the passability of various models is poor. Every time a model is updated, a large amount of special equipment that occupies a large share of the workshop's investment needs to be updated. Therefore, the mixed-flow flexible technology of the welding production line has attracted extensive attention from domestic and foreign automobile manufacturers. [0003] Automobile flexible welding production is a high-volume, high-intensity, high-strength production operation process. The previous production mode with manual operations as the main body is gradually replaced by fully automated robot arm operations. However, the control system of welding...
