The laser antenna comprises an antenna radiator (1); antenna emitters (2) are arranged around the antenna radiator (1); low-temperature welding solder paste (3) is arranged on the antenna emitters (2); welding elements (4) needed by the antenna are arranged on the low-temperature welding solder paste (3). The manufacturing method of the laser antenna has the advantages that (1) the antenna emitters are arranged on the antenna radiator; (2) the low-temperature welding solder paste is printed on the antenna emitters by using a steel mesh; (3) welding is performed and the elements are attached after the low-temperature welding solder paste is printed. The antenna has the characteristic that the elements can be welded on the radiator antenna surface of an antenna plastic part, and expected free design and optical performance effects can be achieved by means of routing of an LDS (Laser Direct Structuring) antenna. Meanwhile, an antenna route and welded elements can be designed on any region of the radiator in order to meet various antenna performance and appearance requirements.
Description
Technical field
The present invention relates to a kind of laser antenna and preparation method thereof, be specifically related to be a kind of common plastic parts use can welding component laser antenna and preparation method thereof.
Background technology
Information technology is flourish now, people are more and more diversified to the demand of electronic product, following the trend in epoch, people pursue under the trend of ultra thin handset at present day by day, and to retain the simplification of higher antenna performance and audio performance and antenna structure of mobile phole technique, conventional (laser direct forming Laser Direct Structuring) thunder carving antenna cabling region copper facing/nickel plating/gold-plated, determine behind the position that needs welding component (trying one's best in the three-dimensional surface plane of selective radiation three-dimensional workpiece in welding component region), the steel mesh of opening welding component to brush tin cream, by specific temperature control system and tool, debugged welding component again, thereby make the LDS(laser direct forming Laser Direct Structuring of common plastic material) normally can weld the components and parts that various antennas are relevant in antenna surface, the way of this kind of traditional welding technique cannot be at LDS(laser direct forming Laser Direct Structuring) weld on common plastic parts, common plastic parts cannot carry tin cream melt temperature, LDS(laser direct forming Laser Direct Structuring before tin cream does not also melt) plastic parts has just melted or gross distortion, therefore cannot meet the free design of present antenna for mobile phone cabling and the optimum efficiency of antenna performance and quality.
Summary of the invention
The object of the invention is to overcome the above problem that prior art exists, a kind of antenna for welding component technique in laser antenna surface is provided, be traditional LDS(laser direct forming Laser Direct Structuring) thunder carving antenna cabling, thus better solve the knotty problem of above-mentioned antenna circle.Thereby do not affect whole antenna appearance effect, meet the configuration design of interior of mobile phone/mobile phone and quality requirements.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention uses by following a kind of common plastic parts can welding component laser antenna, comprise antenna radiator 1, the surrounding of described antenna radiator 1 is provided with antenna transmission body 2, on described antenna transmission body 2, be provided with soldered tin cream 3, on described soldered tin cream 3, be provided with the required welding component of antenna 4.
Welding component in described laser antenna surface, realizes this kind of technique and is: described welding component 4 is directly welded on compact antenna radiant body by soldered tin cream 3, and described soldered tin cream is the tin cream that fusing point is lower; It is the tin cream of 138 ℃ that described soldered tin cream is preferably fusing point.Special with temperature control system and tool, laser welding special parameter is preferably: 0-5kg, and temperature: 150 ℃-200 ℃, time: 8-10s, highly: 3-6mm.
Common LDS material temperature is controlled at 150 ℃ of left and right, air pressure is controlled at 2Kg, time is controlled at 8s, height is determined by components and parts height, in order to improve, to weld the finished product yield of making and make efficiency, the too high common material gross distortion of LDS that easily causes of welding temperature, cannot meet quality requirements, air pressure and weld time are extremely important too, air pressure is greater than 2KG and is easy to the components and parts stripping of pre-welding to fall, cause finished product welding component device to lack, affect final antenna performance, preferentially be chosen in 8s through checking weld time, if weld time is long, easily cause scolding tin and components and parts skew, also easily cause the quality problem such as LDS plastic parts local deformation simultaneously, if there is the phenomenon of slight deformation or components and parts skew in antenna welding component region, should suitably reduce air pressure and temperature is adjusted bad phenomenon, slowly adjust weld time simultaneously, until welding product reaches optimum efficiency.
The invention has the beneficial effects as follows: technical scheme of the present invention has at any LDS(laser direct forming Laser Direct Structuring) feature of welding component in the radiant body antenna surface of antenna plastic parts, make LDS(laser direct forming Laser Direct Structuring) thus antenna cabling can reach freely designing of expection and optimum performance effect, antenna cabling and welding component can design the arbitrary region at LDS radiant body simultaneously, meet various antenna performances and appearance requirement.Make antenna for mobile phone have more integrated feature, thereby make more massive commercialization and family expenses in hand-held electronic product become possibility.

Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the present invention in detail.
Shown in Fig. 1/Fig. 2, a kind of common plastic parts is used can welding component laser antenna, comprise antenna radiator 1, the surrounding of described antenna radiator 1 arranges antenna transmission body 2, described antenna transmission body 2 is provided with special welding low temperature tin cream 3, on described special welding low temperature tin cream 3, is provided with the required welding component of antenna 4.
Shown in Fig. 2/Fig. 3, according to required LDS antenna plastic cement material, antenna traces Direct Laser is radium-shine to LDS plastic rubber member surface, utilize the three-dimensional surface of three-dimensional workpiece to form antenna circuit structure.On antenna circuit surface, need steel mesh printing soldered tin cream for welding component region, after paste solder printing is good, with welding robot, first tentatively post components and parts simultaneously.Wherein parameter is: special with temperature control system and tool, and laser welding special parameter/air pressure: 5kg, temperature: 200 ℃, time: 8s, highly: 3mm.
With special temperature control system and heating head, solidify components and parts and low temperature tin cream again, by special welding parameter and low temperature tin cream after optimizing, carry out solidified welding components and parts, given full play to freely designing and advantage that components and parts are integrated of common LDS material laser welding component, adopt this parameter of organizing special laser thunder carving antenna surface welding component technique the components and parts that need to be welded in the antenna surface of the common material of LDS (components and parts can append different model and quantity according to the requirement of antenna adjustment), make its welding component antenna cabling freely generated on radiant body plastic parts, can optimize antenna performance simultaneously, compare traditional LDS antenna performance more, cabling is more flexible, antenna device is integrated more, benefit is better, this welding has not only improved properties of product greatly, also shortened the mobile phone production cycle simultaneously, a lot of unnecessary links have been reduced, by using the special welding parameter of this group directly components and parts to be welded to the technique in the common material antenna surface of LDS, avoided to a great extent the disappearance of traditional handicraft.
