Abstract

The invention discloses a safety controller for a welding robot and a control method thereof. The safety controller comprises a safety protection module, an upper computer, an execution module, a running information acquisition module and a field bus, wherein, the upper computer and the running information acquisition module send a parameter initialization data command and a robot running state command to the safety protection module via the field bus; the safety protection module sends alarm and error indication to the upper computer via the field bus; and the execution module receives output of the safety protection module. The safety controller and the control method thereof have the beneficial effects that connection complexity is greatly reduced by adopting a field bus technology; and a safety area protection function is realized by means of a plurality of safety protection strategies, namely, corresponding alarm or error message prompt is given out in case of abnormalities, and meanwhile corrective measures or emergency shutdown are carried out, thus ensuring safety operation of a system.

Description

technical field [0001] The present invention relates to a safety controller and a control method thereof, in particular to a safety controller for a welding robot and a control method thereof. Background technique [0002] With the wide application of welding robot technology in modern manufacturing industry, its safety protection has attracted people's attention. As a high-speed operating equipment with multiple degrees of freedom, although a lot of protection work has been done in the pre-programming, there may still be safety hazards and even accidents under different working conditions. Especially in manual participation such as teaching and maintenance, on-site personnel's misoperation, hardware errors and unknown system design defects may cause huge damage. Therefore, necessary safety facilities must be set up in the workplace of welding robots to prevent accidents. [0003] In the welding robot system, the traditional signal transmission and acquisition is realized ...
