Robot welding signal collection multi-channel converter

Abstract

The invention relates to a robot welding signal collection multi-channel converter. The robot welding signal collection multi-channel converter comprises a cabinet (1), the top of the cabinet is provided with a DC24V power connection end (11), an Ethernet communication interface (12) and a PROFIBUS-PA communication interface (13), a connection terminal (21), a programmable controller (22), a DP communication module (23) and a digital quantity input and output module (24) are arranged in the cabinet, the DP communication module (23) is clamped between the programmable controller (22) and the digital quantity input and output module (24), and the DP communication module (23), the programmable controller (22) and the digital quantity input and output module (24) are perpendicularly arranged in parallel. The converter is characterized in that a counter is further included, coupled into the programmable controller (22) and used for calculating the number of conditions that the interfaces and the modules experience abnormality; when the number reaches a preset value, the programmable controller (22) gives out an alarm signal.

Description

technical field [0001] The invention relates to a robot automatic welding device, in particular to a robot welding signal acquisition multi-channel converter. Background technique [0002] At present, the automobile industry is developing rapidly. In order to pursue high-quality and high-efficiency products, to save production costs and increase production capacity, and to adapt to the process of industrialization, robot automation control and welding are widely used in the field of automobile manufacturing. Especially in the field of automotive body welding, automakers and auto parts producers are increasingly inclined to use robots to automate welding. [0003] However, in order for the robot to realize automatic welding, it must first complete the signal connection between the robot and the welding controller. Only when the welding signal is satisfied can normal welding be performed. Therefore, a device is needed to establish the signal connection between the robot and t...
