Abstract
The utility model discloses a micro-electric-wire manufacturing system which sequentially comprises a drawing device, a tin plating device, a stranding device, an annealing device and an extrusion insulating device. The annealing device is arranged behind the tin plating device and the stranding device sequentially rather than behind the drawing device, so that excessive local annealing and tensile strength reduction before single metal wires are fed into the tin plating device and the stranding device during manufacturing of micro-electric-wires are avoided, and the breakage probability of the single metal wires when being fed to the tin plating device to be subjected to tin plating and when being fed to the stranding device to be stranded is lowered. Besides, since the annealing device is arranged behind the stranding device, residual stress inside stranded conductors of the micro-electric-wires can be eliminated thoroughly after the wires are fed to the drawing device and the stranding device, twisting of the micro-electric-wires produced by a conventional electric-wire manufacturing system is eliminated, and the bending life of the micro-electric-wires is longer.
Description
Technical field
The utility model relates to electronics line processing technique field, is specifically related to a kind of extrafine electronic wire manufacturing system.
Background technology
Because development of electronic technology; Terminal consumption electronic product miniaturizations day by day such as mobile phone, digital camera, notebook computer; In order to practice thrift the inside usage space of end product, become the preferential selection of electronic product manufacturer as the interconnector of end product with extrafine electronic wire doubling place of flexible circuit board.Extrafine electronic wire is meant that conductor diameter is at 0.3mm and following; The insulating barrier external diameter is at 1mm and following electronics line products; Its conductor material adopts tinned wird or tin-coated copper alloy wire usually, and insulating material adopts fluoroplastics such as tetrafluoroethene-perfluoroalkyl ethylene oxy copolymer or solid perfluoroethylene-propylene usually.The conductor of extrafine electronic wire can be a monofilament, also can be twisted together by multifilament and form.Because the conductor that the conductor of the stranded formation of multifilament constitutes than monofilament has better flexibility and the life-span is reversed in bending, so the extrafine electronic wire conductor forms by multifilament is stranded usually.
Conditional electronic line manufacturing system comprises successively: wire-drawing frame, annealing device, tinning stack, stranded wire apparatus and extruded insulation device; Further, annealing device and said tinning stack are connected in the device usually described in the said conditional electronic line manufacturing system.At present, extrafine electronic wire still adopts conditional electronic line manufacturing system to produce, and at first, the former material of extrafine electronic wire metallic conductor is processed into the extrafine electronic wire metal monofilament of required size and anneals under 350～520 ℃ of temperature through annealing device through wire-drawing frame; Secondly, it is zinc-plated that the extrafine electronic wire metal monofilament after the annealing gets into tinning stack; Once more, the extrafine electronic wire metal monofilament after zinc-plated gets into the stranded wire apparatus twisted wire; At last, the metallic conductor that obtains through twisted wire gets into extruded insulation device extruded insulation, obtains the extrafine electronic wire finished product.
