Abstract

The invention relates to a welding method and a welding system for an electrode sheet of a surge protector. The welding method provided by the present invention includes: providing a surge protector to be welded, the surge protector includes a housing, a slider and an electrode sheet, the slider is arranged between the housing and the electrode sheet, the electrode sheet includes a welding end, The shell is provided with a pad area for welding electrode sheets; inject solder paste into the pad area, attach the solder end to the solder paste, and obtain the first workpiece; obtain the first workpiece, adjust and fix the solder end and pad The distance between the areas, so that the thickness of the solder paste is less than or equal to the distance between the slider and the pad area, and the solder paste is filled between the solder end and the pad area, and part of the solder paste is squeezed to the outside of the solder end edge, get the second workpiece; get the second workpiece, and perform reflow soldering. Under the premise of not affecting the safety protection effect of the surge protector, qualified solder joints can be obtained, and the welding defect rate can be reduced. It is suitable for mass production of surge protectors with excellent performance and stability.

Description

technical field [0001] The invention belongs to the technical field of surge protector preparation, and in particular relates to a welding method and a welding system for electrode sheets of a surge protector. Background technique [0002] Surge protector is an electronic device that provides safety protection for various electronic equipment, instruments and meters, and communication lines. When the electrical circuit or communication line suddenly generates a peak current or voltage due to external interference, the surge protector can conduct the shunt in a very short time, so as to avoid the damage of the surge to other equipment in the circuit. The shell and the electrode sheet are the core components of the surge protector. The shell is provided with a pad area, and the welding end of the electrode sheet is welded to the pad area. The welding performance of the electrode sheet and the pad area directly affects the safety protection effect of the surge protector. When...
