Multihead temperature control electric soldering iron

Abstract

The invention provides a multihead temperature control electric soldering iron which comprises two or more soldering iron heads, heating cores, a connecting rod, a handle and a power supply wire, wherein the heating core is positioned in a cavity of each soldering iron head, and fixed screws are arranged on the soldering iron heads and used for fixing the heating cores and the soldering iron heads into a whole; both the heating cores and the soldering iron heads are fixed on the connecting rod; the connecting rod is fixed on the handle; a temperature control button is arranged on the surface of the handle, and a temperature control circuit is arranged in the temperature control button. The multihead temperature control electric soldering iron is characterized in that an adjusting disk is arranged between the soldering iron heads and the connecting rod; and the adjusting disk comprises a fixed knob and an adjusting knob. Because the multihead temperature control electric soldering iron is provided with a plurality of soldering iron heads, a plurality of pins can be welded or a plurality of elements on a circuit board are simultaneously disassembled according to the requirement, and the working efficiency is improved; and the invention shortens the working time of the electric soldering iron, reduces loss, prolongs the service life and simultaneously saves electric energy.

Description

technical field [0001] The invention relates to an electric soldering iron, in particular to a multi-head temperature-controlled electric soldering iron for LEDs. Background technique [0002] LED welding is an important link in the production of LED products. Due to the particularity of LEDs, the acceptable welding conditions are relatively strict. Usually, a temperature-controlled soldering iron is used to solder the LED pins to the PCB circuit board. Currently, it is commonly used Most temperature-controlled soldering irons are usually single-headed soldering irons, so you can only solder the pins to the circuit board one by one or remove the components from the circuit board one by one. [0003] Soldering with a single-headed soldering iron has the following disadvantages: 1. Every time you solder, you must first heat the soldering iron to a sufficient temperature, then dip it in solder rosin for soldering, and finally clean the solder on the soldering surface, so solder...

Problems solved by technology

[0003] Soldering with a single-headed soldering iron has the following disadvantages: 1. Every time you solder, you must first heat the soldering iron to a sufficient temperature, then dip it in solder rosin for soldering, and finally clean the solder on the soldering surface, so soldering The more the number of times, the greater the workload, the lower the work efficiency, and more manpower is required; 2, due to the continuous heating of the electric soldering iron for a long time, it is easy to damage the electric soldering iron, shorten its service life, and consume a lot of energy at the same time. electrical energy

Also using a single-head soldering iron for disassembly has the above-mentioned shortcomings
