Description

technical field [0001] The invention relates to the technical field of micro-spot welding, in particular to a pressure control device and a pressure control method of a micro-pressure regulating device. Background technique [0002] The micro-pressure adjustment device is one of the components of the micro-spot welding system. The micro-spot welding system can realize automatic hot-press welding of extremely small diameter wires. The core function of the pressure actuator of the micro-pressure adjustment device is the precise output of micro-pressure. The pressure actuator of the existing micro-pressure regulating device can only set the output pressure. If the shell is partially replaced or the installation method is changed, the pressure output end of the precision press head acts on the equivalent pressure of the internal mechanical structure of the pressure actuator shell. Unknown changes in force often cause the actual output pressure at the end of the precision press h...

AI Technical Summary

Problems solved by technology

The pressure actuator of the existing micro-pressure regulating device can only set the output pressure. If the shell is partially replaced or the installation method is changed, the pressure output end of the precision press head acts on the equivalent pressure of the internal mechanical structure of the pressure actuator shell. Unknown changes in force often cause the actual output pressure at the end of the precision press head to deviate from the set output pressure during work

Furthermore, when the pressure actuator of the micro-pressure regulating device starts to work according to the set output pressure, the terminal output pressure is accurate, but after working for a long time, if the terminal output pressure drifts and exceeds the required pressure range, conventional precision presses header cannot find the problem
