Abstract

The invention relates to a welding method and system for an electrode plate of a surge protector. The welding method provided by the invention comprises the steps that the surge protector to be weldedis provided, wherein the surge protector comprises a housing, a sliding block and the electrode plate, the sliding block is arranged between the housing and the electrode plate, the electrode plate comprises a welding end, and a bonding pad area used for welding the electrode plate is arranged on the housing; solder paste is injected into the bonding pad area, the welding end is attached to the solder paste, and a first workpiece is obtained; the first workpiece is obtained, the distance between the welding end and the bonding pad area is adjusted and fixed, the thickness of the solder pasteis smaller than or equal to the distance between the sliding block and the bonding pad area, the space between the welding end and the bonding pad area is filled with the solder paste, part of the solder paste is extruded to the edge of the outer side of the welding end, and a second workpiece is obtained; and the second workpiece is obtained, and reflow soldering is conducted. On the premise thatthe safety protection effect of the surge protector is not affected, qualified welding spots are obtained, the welding reject ratio is decreased, and the welding method and system are suitable for mass production of the surge protector with excellent and stable performance.

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...
