Summary: Make to comply with automobile body " light quantify, safety and energy-saving " development trend, laser spells solder board to get applied extensively in automobile production industry. Laser spells solder board is the spring that reachs different ply, capable person exterior position character uses laser beam welding to receive equipment to solder together, strong suppress causes a part, in order to satisfy the different requirement of pair of material function and ply. Introduced laser to spell the application of solder board technology, advantage and workmanship, its application came true to reduce automobile body quality, increase automobile body stiffness, reduce automobile body spare parts to assemble an amount, rise assemble precision and the goal that reduce a car to make cost. Car production domain is current the trade that the most large-scale use laser beam welding accepts a technology, from car component production is made to automobile body, laser beam welding is received in becoming a car to make production important solder one of methods. Laser spells solder board is film of will different face, material 2 when reach ply character or many armor plate solders through laser methodological joining together becomes wool blank together, cause component to suppress in the automobile factory next. Because its have the quality of free combination, can have different board joining together, solder to make medium main application in car automobile body as laser, came true to reduce automobile body quality, increase automobile body stiffness, reduce automobile body spare parts to assemble an amount, rise assemble precision and the goal that reduce a car to make cost. The application that 1 　 laser spells solder board from 20 centuries 80 time metaphase begins, laser spells solder board to was in Europe, United States and Japan to get paying close attention to extensively as new technology. Laser spells solder board craft to basically undertake for automobile industry form a complete set serves, produce in automobile body especially, make and design a respect, laser spells the use of solder board to having huge advantage. Current, the component of car automobile body that spells solder board production by laser basically has around door inside board, around carling, side wall, motherboard, automobile body the A of two side, b, inside C column, wheelhouse and back door board wait [2] , among them, inside the door board use this technology most, it is next before carling. What wait according to spare parts structure, function and overall material utilization factor is different, laser spells solder board solder form. After 2 　 laser spells the applied advantage laser of solder board to spell solder board to apply on car product, improved each truckload performance effectively, and be being reduced make cost respect have distinct advantage. Use laser to spell solder board and contrast of workmanship of traditional component product, its advantage, if express,1 is shown. For function of structure of product of test and verify, have impact test to spelling solder board by the laser of the U of armor plate strike out of 3 different intensity bridge. The two end when requirement happening collides;burst;ulcerate;fester shrink suck can, original figure carries among. Can see, according to design requirement two end;burst;ulcerate;fester after collision shrink absorb bump energy, among do not have basically be out of shape. The composition that 3 　 laser spells solder board equipment and technological process produce equipment to basically be comprised by 3 parts. 1) transform device: Include to go up next the skip, robot that tear open a battlements, change trains robot, makings robots, magnetic conveyer belt, make shallow hole device and stow robot; 2) laser beam welding receives facility: Include fixed position workbench and laser welder; 3) detect equipment: Include online nondestructive to detect equipment and detect robot. Laser spells solder line model. Main technological process includes 5 fields. 1) expect a production. plate material or metal tape material cuts out the makings that books dimension and appearance piece, general use open a book to read falls makings line and place those who cut equipment to have board to cut out, assure to cut out precision reachs the good quality that cut a margin necessarily. 2) go up material process. Through going up the skip, robot that tear open a battlements and change trains robot will expect piece place clamp tabulator. 3) intensify fixed position. The course books 2 fixed position of a workbench and workbench of fixed position of essence of life, will expect an exact location, preparation solders. 4) laser spells solder. When laser spells solder, want to assure good economy already, want to make sure whole welding line is balanced again, welding line width is equal to the ply of original material to have better plasticity, namely punch deformation ability, welding line intensity not under succumb in material be solderinged the intensity of the stuff with low intensity. 5) next makings, welding line detects. The board makings that is over solder through the robot grabs and erect, wait for detect the robot detects after ending, put board stuff magnetic conveyer belt. Current and certain solder equipment has supervisory system of online uninterrupted quality, can soldering be opposite in the process welding line position, clearance, appearance and weld defects undertake quality detects. Spell blemish of solder welding line to laser, can use electromagnetism acoustics law (use transverse polarization planar wave) and the traditional method such as smooth fluoroscopy of X of small central issue detects, also can photograph with optics resemble undertake appearance and local defect detect. 6) make shallow hole, stow and sampling observation process. After laser spells solder to finish, because board makings has ply difference, the ply when piling up to compensate board makings is different, shallow hole is dug in board makings, make sure caboodle is neat when stow. Board makings hits what shallow hole finishs board makings by stow robot to fold put. When need undertakes detecting artificially, stow robot can put board stuff detect on the wall, artificial its from outside the line moving inside the line, in all fronts the circumstance of ceaseless machine falls, undertake selectiving examination artificially. When undertaking manufacturing sampling observation to spelling quality of area of solder board solder, basically should detect the intensity of welding line and plasticity, include the test of mechanical to welding line and solder area physics function. 4 　 laser spells solder board quality to ask laser spells solder board to solder the quality blemish of easy generation after finishing. Quality controls a standard to be: Fluctuation depth of concavity must not exceed 10% of laminose ply; Fluctuation is raised 20% what cannot exceed laminose ply; The deepness side fluctuation fault must not exceed 10% of laminose ply. Laser spells law of proved recipe of check of experiment of solder board quality to use metallic cupping experiment to detect, after metallic cupping experiments detect result. 5 　 conclusion will be decreased as auto industry heavy, energy-saving, decrease platoon and the development climate that improve car passivity security to serve as a car, laser spelled solder board to receive a large number of application. On structural member of white automobile body use laser spells solder board, can reduce automobile body quality, improve safety performance significantly. In punch process, material can get reasonable use, reduced percent defective, reduce pair of punch moulds at the same time, assemble clamping apparatus to reach solder of equipment use, reduced production cost. What spell solder board because of this laser is many the inevitable trend that applying is auto industry development. CNC Milling CNC Machining
