Electric welding pen for circuit board maintenance

Abstract

The invention discloses an electric welding pen for circuit board maintenance. The electric welding pen comprises a pen holder, wherein the outer surface of the pen holder is movably connected with ananti-slip sleeve, one end of the pen holder is fixedly connected with an adapter rod, one side of the adapter rod is movably connected with a welding head, the bottom of the pen holder is movably connected with supporting columns, the tops of the support columns are connected with tobacco pipe hinges in a hinging mode, the bottoms of the tobacco pipe hinges are fixedly connected with main rods, extension rods are embedded in the main rods, the front surface of the pen holder is embedded with a display screen and a switch, the other end of the pen holder is movably connected with a knob, the outer surface of the pen holder is electrically connected with a wire, and the pen holder is electrically connected with a plug through the wire. According to the electric welding pen, the anti-slip sleeve, a thermal-protective coating, the supporting columns and the adapter rod are arranged, the fatigue caused by long-time high-precision work of workers is avoided, errors are reduced, the electricwelding pen can adapt welding work under different conditions by replacing the electric welding heads, the hand burden of workers is reduced, and the functionality and practicability of the device isenhanced.

Description

technical field [0001] The invention relates to the technical field of electric tools, in particular to an electric welding pen for repairing circuit boards. Background technique [0002] Soldering pens are also called electric soldering irons. According to the mechanical structure, they can be divided into internal heating electric welding pens and external heating electric welding pens. They are essential tools for electronic production and electronic maintenance. The main purpose is to weld components and wires, and they are widely used in the electronics industry. . [0003] But the existing electric welding pen for repairing the circuit board, when the circuit board is processed, because the welding part is not the same, so the specification requirements for the welding joint are also different, often need to replace the electric welding pen, and welding the circuit board is a delicate task. In operation, the staff are prone to fatigue due to continuous high-precision ...
