Description
Technical field
The present invention relates to a kind of keyboard and keyboard assemble method, and especially, the present invention relates to a kind of keyboard and assemble method thereof that uses welding manner to combine.
Background technology
General common on the market electronic installation input unit (the for example keyboard of computer or personal digital assistant) is to use the loam cake of screw fixings input unit and base plate to assemble.Firm for input unit, the size of employed screw must be greater than certain standard.Yet because electronic industry tends to miniaturization, and the input unit of use also tends to than small size and than minimal thickness, area that screw takies and thickness will limit the miniaturization of input unit in recent years.
On the other hand, welding job is a considerable link in electronic component and the electronic equipment manufacture craft.The purpose and the method for welding are heating of metal, make metal melting so that engage.In recent years, the high power laser light solder technology is extensively applied to each field, and for example auto industry, medical apparatus and electronic component etc. need precision machined industry.
Laser welding has multiple advantages, for example: not influenced by the geometry of workpiece and weld locations, as long as laser light energy gets at and reaches the place and can weld; Laser light energy in very small region, quite is fit to the welding job of high precision with concentration of energy; Its short operating time and can not change and be soldered the thing characteristic, the welding particular importance of this characteristic between different materials; And advantage such as can in all gases, magnetic field or electric field, weld.Because laser welding has above advantage, therefore be applicable to very much national defence, boat too, accurate industry such as automobile and electronics industry.
Therefore, the present invention provides a kind of use welding manner, and especially, the keyboard that uses the laser welding mode to assemble is to meet miniaturization and light-weighted trend.
Yet, even laser welding is also kept away the problem that the residual stress that is unavoidably produced because of the heat welded workpiece causes material deformation.Though the residual stress of laser welding is little than traditional welding, because its workpiece has less area, volume or thickness usually, the deformation quantity that residual stress causes has significant impact for the desired precision of workpiece, and then reduces product percent of pass.
The object of the present invention is to provide a kind of method of auxiliary welding to assist the welding keyboard, to address the above problem.
Summary of the invention
A category of the present invention is to provide a kind of keyboard and assemble method thereof that combines with welding manner.
According to a specific embodiment, keyboard of the present invention comprises first housing, second housing and a plurality of button.Wherein, first housing comprises a plurality of peristomes; Second housing comprises a plurality of weld parts.Button is arranged on second housing, and its part is placed in the peristome of first housing.In this specific embodiment, the weld part of second housing combines with welding manner with first housing.In addition, the weld part of second housing has projective structure, and this projective structure forms with impact style punching press second housing, but and this projective structure butt first housing to help welding.
