Non-solder laser welding method and device of network transformator

Abstract

The present invention provides a solderless laser soldering method of a network transformer. The lead wire of a magnetic loop coil is wound on a clamp, so that the magnetic loop coil can be fixed in the clamp; a pin frame is fixed on a working platform; the magnetic loop coil is fixed on the pin frame; a computer controls scanning vibrating mirrors to locate a laser beam to the first pin of the pin frame, and two types of lasers are emitted in succession to fulfill the gasification of coating lacquer and a soldering operation; the laser beam is located to the next pin of the same row of the pin frame to repeat the gasification of coating lacquer and the soldering operation, and the process is repeated until all the pins are soldered; the laser beam is located to the positions nearing the outside lead wires of the clamp on soldering spots, a third type of laser is then emitted to cut off excessive lead wires which are used to fix the magnetic loop coil before soldering, and therefore a network transformer is soldered. The solderless laser soldering method, which has the advantages of high soldering speed, firmness, good appearance and no need of complex manual winding, solder and manual soldering, follows the current trend of the unleaded soldering of electronic components and can realize production line operation and mass automatic production.

Description

technical field [0001] The invention relates to a solderless laser precision welding technology, in particular to a solderless laser welding method and device for a network transformer. Background technique [0002] With the invention of computer technology and communication technology and the popularization of the Internet, network transformers have been widely used, and have become indispensable devices in the fields of computers, communications, routers, switches, power supplies and other networks and communications. The network transformer is composed of a magnetic ring coil 2, a corresponding connecting pin 1-1 of the pin frame 1 and a packaging shell 3, and the magnetic ring coil 2 is composed of an iron core 2-1 and a wire 2-2 surrounding the iron core (such as Figure 1~5 As shown), the wire 2-2 of the magnetic ring coil 2 and the connecting pin 1-1 are integrated by welding, the magnetic ring coil 2 and the connecting pin 1-1 are welded, and the plastic shell 3 is us...

Problems solved by technology

[0004] This traditional network transformer brazing method has disadvantages such as the need to manually wind the wires to the welding pins, welding requires solder, low production efficiency, weak solder joints, and unsightly welded parts, which cannot meet the needs of current network transformers. The actual needs of modernization, lead-free, and automated production
