However, due to the high price of gold wires, the cost of LEDs is higher. Therefore, gradually reducing the use of gold wires will be the development trend of LED packaging in the future.
[0004] There are also manufacturers who use alloy wires or copper wires instead of gold wires. Since alloy wires or copper wires are easily oxidized during welding, a device is needed to prevent the connecting wires from being oxidized. The existing anti-oxidation devices are not only large in size, It takes up a lot of space, and when working, the nitrogen content around the connecting wire cannot be guaranteed, which will easily lead to the oxidation of the connecting wire, high scrap rate and high cost

The invention discloses an anti-oxidation device for LED connecting wire welding, which comprises a body, a spark rod, a gas storage space and a nitrogen gas intake channel. A through hole is longitudinally arranged in the middle of the body, and a spark rod is transversely inserted into the body. One end of the ignition rod is close to the through hole; the other end of the body is connected with a nitrogen gas intake channel, and the nitrogen gas intake channel forms a gas storage space at the through hole, and the nitrogen gas intake channel The two sides are respectively provided with a first exhaust hole and a second exhaust hole. The invention has reasonable design, novel concept, significant improvement and obvious technical effect compared with the traditional anti-oxidation device, can effectively guarantee the nitrogen content when LED connecting wires are welded, and has huge market value.
Description
technical field [0001] The invention relates to the technical field of LEDs, in particular to an anti-oxidation device for welding LED connecting wires. Background technique [0002] The connection wire plays a role of a wire connection in the LED package, connecting the electrode on the surface of the chip and the bracket. When the current is turned on, the current enters the chip through the connection wire to make the chip emit light. [0003] Because gold wire has the advantages of high electrical conductivity, corrosion resistance, and good toughness, compared with other materials, its biggest advantage is oxidation resistance, which is the main reason why gold wire was used in LED packaging before. However, due to the high price of gold wires, the cost of LEDs is higher. Therefore, gradually reducing the use of gold wires will be the development trend of LED packaging in the future. [0004] There are also manufacturers who use alloy wires or copper wires instead of g...
