The invention discloses a device and a method for improving energy output stability of a spot welder. The device of the invention comprises a commercial power detection module, a controller and a switch regulating circuit; an input end of the commercial power detection module is connected with commercial power voltage; an input end of the controller is connected with an output end of the commercial power detection module; two input ends of the switch regulating circuit are respectively connected with outputs of the commercial power voltage and the controller; an output end of the switch regulating circuit is connected with an input end of the spot welder; the controller is used for generating a feedback parameter by comparing a detection voltage value which is inputted into the controller with a standard value and for sending out an information instruction to the switch regulating circuit according to the feedback parameter so as to regulate output voltage of the controller. By utilization of the invention, voltage inputted to the spot welder can be stabilized and the energy output stability of the spot welder can be improved, thereby desoldering and firing phenomena during the process of spot welding a nickel strap due to variation of the commercial power voltage are avoided.
Description
technical field [0001] The invention relates to a device and a method for improving the energy output stability, in particular to a device and a method for improving the energy output stability of a spot welder. Background technique [0002] In order to ensure the quality of the spot welding nickel strip, the spot welding machine needs to output stable energy. When the input mains voltage of the existing spot welding machine changes, the phenomenon of explosion and desoldering will occur in the spot welding, which affects the welding quality and seriously restricts the production efficiency. The mains voltage will change due to various reasons. In order to ensure the quality of large-scale spot welding nickel strip production, there is an urgent need for a device to improve the stability of the energy output of spot welding machines. Contents of the invention [0003] The technical problem to be solved by the present invention is to make up for the defects of the prior ar...
