Electric wires winding outside the column-shaped body are cut longitudinally by a cutting tool rotating with a high speed, outer coating insulating layer is removed partially to expose metal portion, a luminous chip is bonded to the metal portion of an electric wire thereof, a metal conductor is connected to a metal portion of another electric wire, and sealing glue is bonded at the external finally to form a luminous element. A LED lamp string is formed after the lamp string is taken off.

Description

LED lamp string manufacture method

Technical field

The present invention is a kind of LED lamp string manufacture method, refers to that especially a kind of is the lamp string manufacture method that illuminator combines with the luminescence chip.

Background technology

Early stage LED lamp string mainly is to make the LED with two lead foots earlier, then two lead foots is connected with the both positive and negative polarity of conductor wire respectively again, to form a lamp string structure.Because LED has directionality, thus when combination, be easy to generate mistake, and it is to utilize artificial combination one by one, also suitable trouble.Therefore, a kind of generation of LED electroluminescent lamp string of improvement is arranged just, utilize luminescence chip to combine, be formed at the illuminator of conductor wire, and obtain the product of similar existing lamp string, for example No. 581188 patent case of the novel bulletin of TaiWan, China with the direct of conductor wire.

Though the LED electroluminescent lamp string of above-mentioned improvement has the exquisiteness of structure and the convenience of use, but on making, it still rather bothers, it is existing manufacture, mainly be to place lead in the mode of straight line ornaments, and then cut a part of insulating surface in every appropriate intervals, to expose its metal part, therefore, it needs very big space, and the mode of its excision insulating surface is for implementing in regular turn, except increasing man-hour, its location is difficult for accurately, have the shortcoming that differs at interval, and the speed of making also can't reach requirement rapidly, historical facts or anecdotes remains to be improved.

Summary of the invention

At the deficiencies in the prior art, the objective of the invention is to: a kind of LED electroluminescent lamp string manufacture method is provided, utilizes and locate composite construction cleverly, can finish the manufacturing of product fast, and have certain effect rapidly, and can operate in limited space.

For achieving the above object, the technical solution used in the present invention is:

A kind of LED lamp string manufacture method, it is characterized in that: prepare a cylindrical body, its surface has at least two helical grooves, a cutter tool, and the conductor wire of lamp string, its manufacturing step is:

(a) in each described helical groove, twine a conductor wire, and make the location, two ends of every conductor wire tight;

(b) cutter is moved along the body axis direction, or cutter is fixed, and mobile body excises outer the cover insulation top layer of conductor wire near the part of cutter, and expose metal part;

(c) therein in the everywhere exposed metal portion of a conductor wire, a luminescence chip is set, oven dry makes its secure bond again;

(d) on each luminescence chip, utilize a wire guide, be connected to the metal part of another conductor wire; Then externally, with oven dry again after the insulation sealant covers, make each luminescence chip form a luminescence unit.

(e) take off conductor wire, promptly obtain to have the lamp string structure of a plurality of illuminators.

Wherein:

Described cylindrical body be shaped as cylindric or elliptical cylinder-shape, the inside of body is provided with axial push rod, and two ends are provided with screw, can rely on to adjust screw, with the upper and lower displacement of control push rod, be can tight location outside conductor wire or it is loosened.

Described push rod is one or more.

The outer helical groove of described cylindrical body is more than two groups or two groups, cooperates the conductor wire of similar number, to make the LED lamp string of different shape.

Compared with prior art, the beneficial effect that has of the present invention is; Design the technology of an automation,, make LED electroluminescent lamp string fast, have best quality and efficient in the mode of working continuously.

The specific embodiment

For being described in more detail manufacture of the present invention, cooperate graphicly now with an embodiment, be described as follows:

(a) as Fig. 1, Fig. 2, the invention provides a cylindrical body 1, be provided with two groups of helical grooves 11 on its surface, the inside of body 1 is provided with one or more axial push rods 12, and its two ends are equipped with screw 13.If described cylindrical body 1 length is oversize, can adopt the push rod 12 segmentation settings more than two or two, these push rods 12 direction preferably in alignment is arranged.

(b) two conductor wires 2 being wrapped in body 1 helical groove 11 outward, as shown in Figure 3, Figure 4, behind the location, two ends, adjusting screw 13 and make push rod 12 outside, is can two conductor wires 2 are tight on body 11, forms locating effect very closely.

(c) utilize cutter 3 to move, or cutter 3 is fixing along body 1 axis direction, mobile body 1 also can, as Fig. 5, excision conductor wire 2 covers insulation top layer 21 near the outer of cutter 3 positions, and exposes metal part 22.

(d) therein in the everywhere exposed metal portion 22 of a conductor wire 2, be provided with a luminescence chip 4, as shown in Figure 6, oven dry makes its secure bond again.

(e) as shown in Figure 7, on each luminescence chip 4, utilize a wire guide 41, be connected to the metal part of another conductor wire; Then externally, with what dry again after insulation sealing 5 coatings,, make each luminescence chip 4 form a luminescence unit as Fig. 8.

(f) adjust screw 13, loosen push rod 12, take off two conductor wires 1 again, promptly obtain to have the lamp string structure of a plurality of illuminators.

In sum, manufacture method of the present invention obviously can be finished the cutting conductor wire fast, in conjunction with luminescence chip and wire guide, and with the sealing sealed insulation, to make LED electroluminescent lamp string.Because it is external that conductor wire is wrapped in, so can save the operating space, in addition, when cutting vertically with cutter, except that can once cutting simultaneously the conductor wire of many places, its spacing also obtains to guarantee, makes between each illuminator every being unanimity, promptly around the distance in week of body, and obtain best practical effect.

The above, it only is a preferred embodiment of the present invention, all technology of utilizing identical intention to implement, all still be included in the claim of the present invention, for example shown in Figure 9, establish with three groups of helical grooves 11 in the outside of body 1, twine simultaneously for three conductor wires 2, and make a LED lamp string with three conductor wires, make the LED luminescence chip on it have different connected modes, to form the state of beating that can change sequence of light.Certainly, the lamp string of three groups of above conductor wires or provide conductor wire coiling etc. with the body (as ellipse) of other shape is also contained by the present invention.
