Fully-automatic welding gun and using method thereof

Abstract

The invention provides a fully-automatic welding gun and a using method thereof. The welding gun comprises a welding gun body, wherein a heating device is arranged inside the welding gun body; two movable soldering iron heads and a proximity sensing device are arranged on the outer end surface at one side of the welding gun body; the two movable soldering iron heads are symmetrically arranged; a master control single chip microcomputer and a drive device which are connected with each other are further arranged inside the welding gun body; the master control single chip microcomputer is connected with the proximity sensing device; the master control single chip microcomputer is used for sending a proximity signal or a far-away signal to the drive device; and the drive device is used for driving the two movable soldering iron heads to get close to each other or to be far away from each other according to the proximity signal or the far-away signal. The fully-automatic welding gun can combine the actions of fixing an element and welding an element in primary welding, so that welding velocity is improved. Moreover, the fully-automatic welding gun realizes fully-automatic welding and reduces requirements on a welding staff.

Description

technical field [0001] The invention relates to the technical field of welding equipment, in particular to a fully automatic welding torch and a using method thereof. Background technique [0002] At present, most of the electric soldering irons on the market heat the solder by heating the tip of the soldering iron. In this way, another operation is required to fix and place the components before soldering a component. Moreover, this method also has the following two disadvantages: 1), the efficiency of a single soldering iron tip is low, and each component must be soldered at least twice, which greatly reduces work efficiency. 2) The effect is not good when soldering small package size components. Because with the continuous reduction of the size of the components on the circuit board and the complexity of the peripheral circuits of some components, the requirements for welding personnel are getting higher and higher, and the welding cycle is too long.

[0002] At present, most of the electric soldering irons on the market heat the solder by heating the tip of the soldering iron. This method requires another operation to fix and place the components before soldering a component.

And, adopt this method to also have following two disadvantages: 1), the efficiency of single soldering iron tip is low, and each element will be soldered at least twice, greatly reducing work efficiency

2) The effect is not good when soldering small package size components

Because with the continuous reduction of the size of the components on the circuit board and the complexity of the peripheral circuits of some components, the requirements for welding personnel are getting higher and higher, and the welding cycle is too long
