Automatic soldering machine and soldering method thereof

Abstract

The invention discloses an automatic soldering machine and a soldering method thereof. The automatic soldering machine and the soldering method thereof are used for the soldering of a wire and an electronic component. The wire has at least one exposed core wire. The electronic component has at least one soldering part. The automatic soldering machine comprises a plurality of clamps, a programmable control system and a delivery mechanism, a solder paste coating mechanism capable of coating solder paste on the end part of the core wire and the soldering part of the electronic component, a soldering mechanism capable of heating the solder paste and soldering the end part of the core wire with the soldering part of the electronic component and an unloading mechanism capable of breaking the soldered electronic component and wire away from the clamps. The clamps are placed on the delivery mechanism which is controlled by a control system and used for positioning the core wire of the wire and the electronic component. The automatic soldering machine of the invention utilizes the solder paste molten at a high temperature to promote the soldering of the conductor of which the core wire is exposed due to the shrinkage of an insulated cable by using the characteristic that the insulated cable of the core wire shrink once heated, so that the procedure of stripping the insulated cable of the core wire can be saved, the soldering efficiency is high and the soldering raw material solder paste has an accurate using amount and little loss during use.

Description

technical field [0001] The invention relates to an automatic soldering machine, in particular to an automatic soldering machine for welding wires and electronic components and a welding method thereof. Background technique [0002] HDMI connection cables, USB connection cables, and other connection cables connected between electronic devices need to be welded to the soldering portion of the conductive terminal of the electronic component during manufacture. Most of the existing connecting wires are manufactured by manual welding with an electric welder, and due to the limitation of the operation method, tin wire is often used as the welding material. [0003] However, in the manual welding operation of the above-mentioned existing connecting wires, before the wires are welded to the electronic components, the oxidized parts of the ends of the core wires in the wires must be manually cut off, and then the oxidized parts of the core wires in the wires must be manually stripped...

Problems solved by technology

[0003] However, in the manual welding operation of the above-mentioned existing connecting wires, before the wires are welded to the electronic components, the oxidized parts of the ends of the core wires in the wires must be manually cut off, and then the oxidized parts of the core wires in the wires must be manually stripped. The insulating skin at the end of the wire exposes the core wire conductor, and then manually operates the electric welder and uses tin wire to weld each exposed core wire conductor to the welding part of each conductive terminal of the electronic component

Manual soldering is not only inefficient, but also unstable in quality and low in yield

The welding head of the electric welder used for manual welding is easy to oxidize, requires careful maintenance, and the service life of the electric welder is short

In addition, tin wire is used as the welding material, and its amount will be lost by 10% to 20% in actual use, so the consumption of raw materials is large.

[0004] In view of the above-mentioned defects in the manual welding operation, there is also a soldering machine in the prior art, which can automatically send tin at a constant speed and quantity, and directly weld the core wire on the electronic component instead of a manual operation electric welder, but still needs manual cutting. wire and manual stripping of insulation, only semi-automatic production can be realized, the production efficiency is low, and the welding material used is tin wire or tin sheet, which consumes a lot of raw materials
