Wide power electronic spot welder

Abstract

The invention provides an electronic spot welding machine with wide power supply, which includes a host, a plate frame and an optical device for users to observe welding spots. The host mainly includes a wide power supply circuit module, a spot welding power control circuit module and a welding Time and voltage drive circuit module, the wide power supply circuit module is used to output the welding energy of AC working voltage; the spot welding power control circuit module uses several power tubes and time-delay insurance tubes to be connected in series respectively; the welding time and voltage One end of the drive circuit module is electrically connected to the wide power supply circuit module, and the other end is electrically connected to the spot welding power control circuit module to control welding time and output welding energy to drive the spot welding head for welding. The invention not only can output a wider range of working voltage, but also has stable output, improves the reliability of the electronic spot welding machine and prolongs the service life.

[0003] The traditional electronic spot welding machine includes the main machine, the plate frame and the pressure device and other equipment. The electronic spot welding machine with this structure has serious defects in the welding process of electronic components. In the past, the main machine used a power transformer as the electronic spot welding machine. The input power of the machine not only adds a transformer, which increases the weight and volume of the equipment, but the most important thing is that the working voltage of the host will fluctuate with the fluctuation of the mains power, thus affecting the stability of the energy output of the spot welding enameled wire If effective control is not taken in the follow-up energy control circuit, there will be a phenomenon of solder joint virtual welding, resulting in a decrease in the high temperature and low temperature resistance of the solder joints, resulting in the unreliability of electronic components. This is the case in microwave communication components and micro An increasingly prominent problem in the electronic component manufacturing industry
