Problems solved by technology

There are overcharging and undercharging during the charging process, so it cannot be discharged under the same energy when discharging, so as not to cause inconsistent welding results, especially when precision spot welding cannot meet the welding requirements
[0003] Secondly, the working method of "connecting dots" is not adopted, so that the production efficiency is low
As mentioned above, the discharge is controlled by the foot switch. When the foot switch is stepped on, the capacitor will be discharged regardless of whether it is fully charged, so the foot switch must be waited until it is fully charged, otherwise the energy is not enough to form a solder joint, so it is difficult Use the shortest time for welding operation after fully charged, which is complicated and inefficient

Embodiment Construction

[0041] Capacitor energy storage spot welding uses capacitors to store energy. When the energy can melt a small area of ​​solder joints, the capacitors are discharged instantaneously. Compared with other welding methods, such as AC, the instantaneous power taken from the grid is low, the load of each phase is balanced, and the power factor is high, and it can provide concentrated energy to the welding area, and can obtain weldments with good surface quality and small deformation. Weld some non-ferrous metals with good thermal conductivity and difficult to weld, suitable for welding aluminum, copper silver, nickel metal and alloy materials. This welding method has been widely used in industrial production, such as hardware, household appliances, electronics, metal utensils and other industries. The welding machine is composed of mechanical parts and electrical parts, and circuit control is the core part of resistance welding technology. Single-chip computer control technology i...

Abstract

A controller of capacitor-type energy accumulating machine for welding is composed of panel consisting of surface film, iron and frame, motherboard containing CPU trigger circuit board, and master controller consisting of step-up transformer, bridge rectifier, charging and discharging SCRs, energy accumulating capacitor, and discharging transformer. Its control method features the program control of charging and discharging.

Description

technical field [0001] The invention relates to a control device and a control method of a welding machine, in particular to a control device and a control method of a capacitor energy storage type energy storage welding machine. Background technique [0002] Most of the existing energy storage machine welding control methods use analog charging, and use a foot switch to directly control the discharge. There are overcharging and undercharging during the charging process, so it cannot be discharged under the same energy when discharging, so as not to cause inconsistent welding effects, especially when precision spot welding cannot meet the welding requirements. [0003] Secondly, the working method of "connecting dots" is not adopted, so that the production efficiency is low. As mentioned above, the discharge is controlled by the foot switch. When the foot switch is stepped on, the capacitor will be discharged regardless of whether it is fully charged, so the foot switch mus...
