Welding process parameter issuing control device based on array passive potential

Abstract

The invention discloses a welding process parameter issuing control device based on array passive potential. The whole device comprises two core modules, namely a main control unit and an electronic potential adjusting unit. The control device achieves communication between the main control unit module and an upper computer through a network interface and receives preset parameter values from the upper computer, and meanwhile the main control unit outputs signals to drive the potential adjusting unit to achieve automatic issuing of welding process parameters. The potential adjusting unit is composed of a decoder, a relay, a relay-resistor array and a potential output interface. The device is mainly used for automatically issuing the technological parameters of the welding machine with the remote control box control interface, the problem that execution is uncontrollable due to the fact that the technological parameters are manually adjusted can be solved, it is ensured that the parameters are executed according to preset technological specifications, and the reliability of welding production and the stability of quality are improved.

Description

technical field [0001] The invention relates to the fields of digital control and welding automation, in particular to a control device for issuing welding process parameters based on an array type passive potential. Background technique [0002] With the development of digitalization, the automatic control of the welding process in modern production is getting more and more in-depth. In many industrial scenarios, there is a demand for remote control of welding parameters. At present, there are methods for issuing welding machine parameters, but they are limited to the following welding scenarios: robot welding, special welding machines, and welding machines that provide digital control interfaces. These release scenarios have two restrictions. One is that it must be a digital welding machine, and the other is that the welding machine manufacturer must provide a digital control interface. This means that a large number of industrial scenarios that use simulated welding mach...

Problems solved by technology

There are already digital potential adjustment unit chips on the market, but the current and voltage ranges are small, and the resistance error is large. At the same time, common digital potential adjustment units have requirements for the current direction, which is not suitable for welding machine process parameters.
