Automatic welder for DC wire of power supply

Abstract

The invention discloses an automatic welder for DC wires of a power supply. The automatic welder comprises a conveying pulling body, jigs, a jig positioning mechanism, a pressing mechanism and a welding mechanism, wherein the conveying pulling body is arranged on a rack along a left-right direction; the at least two jigs are arranged on the conveying pulling body; at least two PCBs of the power supply and DC wires of the power supply are placed on the jigs; a welding station is arranged on the side part of the conveying pulling body; the jig positioning mechanism is arranged at the welding station; the pressing mechanism is arranged on the front side of the jig positioning mechanism; the welding mechanism bestrides the upper side of the conveying pulling body and is arranged correspondingto the jig positioning mechanism, and the welding mechanism solders and fixes the connecting parts of the DC wires of the power supply and the PCBs of the power supply; and the jig positioning mechanism loosens the jigs after being soldered. The PCBs and the DC wires which are automatically conveyed and welded are effectively jointed, the PCBs and the DC wires are clamped stably; and the welding mechanism with a flexible fine tuning function achieves precise welding and automatic smoke exhaust and is high in welding efficiency.

Description

technical field [0001] The invention relates to the field of mechanical automation, in particular to an automatic welding machine for power DC lines. Background technique [0002] The good characteristics of lithium-ion batteries make them more and more widely used in portable products (mobile phones, notebook computers, tablet computers, etc.), and the power supply (portable charger) for lithium-ion batteries is also becoming increasingly popular in design and function. Complete. The power supply is assembled by PCB board, DC line, upper cover, lower cover and other parts to realize circuit conduction. Among them, the circuit conduction of the power supply needs to weld the PCB board and the DC line. One end of the DC line is electrically connected to the wiring hole on the PCB board, and the other end is the power connector. The PCB board is connected to the electrical connection piece of the upper cover. The chip is inserted into the socket, and the power connector is i...
