Production method of double-wire string light

Abstract

The invention relates to a production method of a double-wire string light, comprising: step 1, making wires; step 2, annealing to improve the wire flexibility; step 3, cooling and cleaning; step 4, making wire sheathes; step 5, removing the sheathes, making positive wires and negative wires exposed to form blowtorch legs; step 6, tin-plating; step 7, welding LED chip anodes and cathodes with the blowtorch legs of the positive and negative wires through an automatic blowtorch machine correspondingly, packaging the LED chip and the blowtorch legs with high-permeability epoxy, then putting the packaging into an UV irradiating procuring device through manipulators, fast curing the epoxy under the UV irradiation, and demoulding upon completion of curing; since the enameled wires on the mould are wound directly, the finished product is demoulded to form a string of complete LEDs. The making process is simple, and the complex processing, such as secondary processing, of the traditional LEDs made into the string light is avoided; in addition, the structure is simple, and the use is flexible and convenient.

Description

technical field [0001] The invention relates to the field of lamp strip manufacturing technology, in particular to a production method of a double-parallel wire lamp string. Background technique [0002] Cord light strings are widely used in the decoration of architectural shapes, bridges, arches, corridors, stairs, billboards, etc., and can also be used in car decoration and interior decoration lights. In the existing cord light strings, the LED lamp beads occupy a large volume and require a large number of manual operations. It is easy to operate incorrectly and cause safety hazards, and the light irradiation range of the LED lamp beads is small, and the irradiation is small, and it cannot achieve a full range of 360 degrees. Irradiation; In addition, the power cord is a single thick copper wire that conducts electricity, and it is easy to break if it is twisted too many times, and the flexibility is not enough. At the same time, LED lamp beads need brackets and other mat...

Problems solved by technology

[0005] Step 1: Making wires: Prepare copper alloy materials, check whether there are defects in the appearance of the blanks such as oxidation, burrs, and cracks, store the blanks that pass the inspection and are not processed temporarily, and use the speed of 450 meters to 550 meters per minute for the qualified materials Stretch the copper alloy material to a diameter of 0.2-2.0MM, and perform electro-tinning process on part of the stretched wire to form red tin-plated copper wire; conduct electro-silvering process on the remaining part of the wire to form white silver-plated wire Copper wire, use a precision stranding machine to twist the ultra-high molecular weight polyethylene core wire with a tinned copper wire in a spring curve shape to form a bundle of multi-strand positive wires, use a precision stranding machine to twist the ultra-high molecular weight polyethylene core wire into a spring The curved way and the silver-plated copper wire are combined into a bundle of multi-strand negative electrode wires; the use of ultra-high molecular weight polyethylene core wires and wire twisting can greatly improve the flexibility of the wires, effectively improve the quality of the wires, and are not easy to break and twist , increase the service life; and the wire has a small amount of retractability, which effectively solves the problems of the existing flexible wire light strips that are easily broken after being twisted too many times and not flexible enough;
