Description
Technical field
The present invention relates to a kind of laser soldering device.
Background technology
Since laser was 20th century, the another invention of great significance of the mankind, it is invented in nineteen sixty by American scientist C.H.Townes and T.H.Maiman etc. and laser is the abbreviation of the stimulated emission light amplification of radiation, it is a kind of electromagnetic wave, that its primary condition produced produced by artificial amplification comprises pumping source laser medium resonant cavity etc., laser has high monochromaticjty directionality coherence and brightness, and laser is a kind of novel heat source.
Laser weld is one of importance of laser processing technology application, attract most attention the most promising solder technology and traditional welding method contrasts 21 century especially, laser weld has a lot of advantage, facts have proved, laser weld range of application is more and more extensive, the operable field of conventional bonding technique substantially, laser weld can be competent at, and welding quality is higher, the faster research and development along with new laser welding technology and equipment of efficiency, laser weld replaces traditional solder technology gradually.Since 20 century 70s, be widely used in the every field of industry.
Laser weld belongs to fusion weld, using laser beam as welding heat source, its Fundamentals of Welding are: by specific method excitation active medium, make it in resonator, come and go vibration, and then change into stimulated radiation light beam, when light beam and workpiece contact with each other, its energy is then absorbed by workpiece, can weld when the fusing point of temperatures as high material.The mechanism formed by welding pool divides, and Laser Welding is connected to two kinds of basic welderings
Welding mechanism: heat conduction weld and dark molten (aperture) welding, the heat produced during heat conduction weld diffuses to inside workpiece by heat trnasfer, face of weld is melted, substantially do not produce vaporization phenomenon, the welding deep penetration welding being usually used in low speed thin-wall member makes materials vaporize, forms a large amount of plasma, because heat is larger, front end, molten bath there will be aperture phenomenon deep penetration welding energy thoroughly through welding workpiece, and the large speed of welding of input energy is fast, is current most popular laser weld pattern.
Affect laser weld effect and mainly contain three key elements: LASER Light Source, welding object and weld jig.In actual mechanical process, welding object material is often determined, it is very little to improve space, so extremely important to the design of LASER Light Source and fixture for laser welding, especially the design of fixture for laser welding often determines the quality of laser weld effect.Current fixture for laser welding is normally made to measure according to the shape of welding object, material, the change of welding object each time all will redesign processing weld jig, the design of weld jig not only to spend a large amount of manpower and materials also according to having become a lot of waste, design a kind of variable weld jig, weld clip prodigiosin welds multiple welding object becomes an extremely urgent task.
Give this needs we devise a kind of laser soldering device of variable weld jig, this apparatus design have employed the technology of many uniquenesses, wherein designs the driven Design of LASER Light Source, variable laser weld jig system etc.
