Undertake on facilities of a production Laser Cutting and laser beam welding receive treatment to had become a possibility at the same time, two kinds of treatment can combine a head to finish by, double function comes true through an independent nozzle, exercise of laser of pattern of this kind of rally can shorten craft catenary, reduce manufacturing cost significantly. Plank product (like car assembly) the treatment facilities that wants a course to differ undertakes cut is mixed solder treatment, plank component should undertake machining according to cut, join and soldering measure. Now, we can produce equipment to go up to undertake cut is mixed at the same time in solder machined, the laser exercise of pattern of this kind of rally can shorten craft catenary, reduce manufacturing cost significantly and can more agile ground has production. Managing the cost of 50% above inferior the Laserfac company of treasure offerred a kind of solution, need not change the Laser Cutting of cutting tool and solder assorted head (graph 1) , it can be mixed automatically inside 1s in cut solder between have transition. Compare with traditional technique photograph, accumulate in investment, installed surface, move and the respect such as logistic component is OK and managing 50% even more cost. Because exercise of rally pattern laser raised manufacturing accuracy, also improved the quality of the product thereby. Change in order the problem of conventional technology catenary of generation, because head of constant Tool-Center-Point(TCP) , combination is mixed,aspirant travel can be worn in a clamp cut and solder and solve. Graph after 1 industry robot uses Laserfact to combine a head, became all-purpose 3D cut and solder the system is being produced especially nonlinear when preform, as a result of the accuracy when laminose base is prefab insufficient, can bring about gap of the generation when the brim joins. The demand that this kind of circumstance gauges to the working procedure at the back of prefab cost and juncture is very high, still need additive even. Below this circumstance, undertake to use assorted head type cut is mixed assembling solder offerred new prospect. Assorted head can undertake accurate cut is mixed solder reliably, and need not change cutting tool, the sensor production that also need not be sequel is comfortable the plank part that deserves to use. Demonstrate sample to make, laserfact company used F2-Y to combine a head, it is to be in inferior institute of technology of treasure Frauenhofer laser (ILT) come true on the foundation of research and development. A kind of independent nozzle of ILT research and development can realize the double function that combines a head, allow laser efflux and installation of coaxial of craft air current, assorted head has light to accuse to break couplet function with pneumatic. Although the pressure bear of nozzle system is as high as 30bar (this pressure is very significant to the cut function of working head) , but do not need to use be able to bear or endure optical lens group of high pressure, what can center energy to make the design achieves optical performance thereby is optimal. The lens group module that the working head of industrial version has pattern of a rally to enclose, contain the fast changeover device that protects gas and focusing. Between independent nozzle and protective gas window, module of eject of a many path crosscurrent can protect lens group effectively. Same, the drive of dynamical Z axis that collect mounts is used at interval adjustment. To check production, the fiber laser of a 4kW (core diameter 50 μ M) as efflux source by IPG have the aid of fiber of a craft (core diameter 100 μ M) with combination the head joins, working head itself is with join flange installation on robot of arm of music of a 6 axes, the steeliness of galvanization automobile body that differs with two makes sample part, part thick 1mm and 1. 2mm. The treatment to thin plate above all, with identical outline laser (power 1.
5kW, speed 8m/min) cut two transverse laminose to seaming those who place online sex slide to go up to be able to be driven base. Next, will before two groups of laminose crossing-over of cut, and will two board solder again with same contrail (power 2.
2kW, speed 8m/min) (graph 2) , the cut on the preform that has solderinging finally gives the long opening of two mutual correspondence. Graph head of 2 laser beam machining can be in cut (left) and solder between automatic switch Nextpage although the cut of dispute linear outline and welding line, gather production also can provide high grade cut and welding line (graph 3) . Especially need not welding line dogs system can accurate find solder to receive orbit, because the coordinate system of the machine had passed the Laser Cutting before to remember the position of welding line and strike, it is OK to receive orbit because of this solder easily emersion. Solder quality accords with the rigiddest car occupation standard (graph 4) . Graph 3 with combination the head undertakes type Laser Cutting is mixed assembling solder of treatment nonlinear after preform give typical examples solders, return can be in same close solid is worn go up to undertake optimizing to plank, stiletto, successive rush to cut and cut a margin, increased manufacturing flexibility, can more the variety that economic land adds a product. Later strong cut can oversight welding line and production gives very accurate part. Undertake to preform type produces the treatment production in the small lot in suiting particularly economically assembling. In view of the efflux quality with current laser outstanding technology, taking cut speed and automobile body steel are harder and harder, mechanical cut method is being washed out ceaselessly. Graph the Laserfact of 4 cross section of preform welding line that make with assorted head serve as ginseng exhibit business to be in of association of Frauenhofer of exhibition of industry of 2007 Munich laser exhibit head of the first combination was shown on the stage. Besides the solid laser that has described, laserfact still has it is CO2 laser research and development technically group of lens of new-style water refrigeration. Reduce facility cost Frauenhofer ILT and Laserfact to depending on new technology and new product in machining domain, had very wide market perspective. Muti_function in producing group laser technology to be used at the production of plank component, because improved usability of feed a machine significantly, and the relocate of equipment, reduced the halt time of the use charge of equipment and craft. Muti_function make cannot come true as a result of cost reason up to now for those complex and the manufacturing condition that the product with model various sort created economy, and the requirement that still can satisfy prospective modernization to manufacture a technology. Use combination to can last the head is muti_function the advantage of laser technology, must consider up to now manufacturing structure, if the car is made. Because it is to build the possibility in confine of place of conventional technology catenary, soldering directly the hem with craft advancement accurate travel is prefab, and the cut working procedure after the component solders, be like accurate setting, the accurate cut of edge of the dimension choice of aperture, function, join, and originally the installation after excision solders, closely and prop up etc. In accuracy, function gender and light-duty structure respect can have first-rate products plan.
