The laser welding device provided with the protective facilities is capable of protecting laser protective facilities and preventing the laser welding device provided with the protective facilities from being damaged by splashing high-temperature fragments, and therefore service life of the laser welding device provided with the protective facilities is prolonged. The laser welding device provided with the protective facilities comprises a laser welding device body, wherein the laser welding device body comprises a shielding gas jet-flow device, and a pair of protective glasses is installed under the laser welding device body. The laser welding device provided with the protective facilities is characterized in that a splash shield is arranged under the protective glasses.
Description
Technical field
The present invention relates to the laser welding technology field, be specially the laser soldering device that carries the protection facility.
Background technology
The desirable thermal source that laser is considered to weld, laser weld is one of most important application of laser technology, it is that the light beam that utilizes the polariscope reflector laser to produce makes it concentrate on the light beam that produces huge energy in the focusing arrangement, the process technology that the characteristic of laser beam and matter interaction is welded material (comprising metal and nonmetal).Laser weld has heating and concentrates, the heat input is few, be out of shape little, speed of welding fast (can reach several meters to tens meters of per minutes), the welding depth-to-width ratio is large, quality is high, not only is suitable for conventional material, also is particularly suitable for refractory metal, it is inflammable to be heated near the workpiece that thermalloy, dissimilar metal, volume and thickness difference that titanium alloy thermophysical property difference is large are large and the weld seam, is heated and easily splits and the explosive member that is heated.Weld seam is attractive in appearance, beautiful, and weld seam can be strong with mother metal etc. in many situations.And laser beam can transmit by optical fiber, therefore can save complicated light beam transfer system, is applicable to flexible manufacturing system or long-range processing.Laser weld both can be spot welding, also continuously seam weldering.
When carrying out laser weld, high temperature during owing to welding, weldment can melt generation chip to a certain degree, and these high temperature chips are splashed on the lens and can damage lens.Improvement between the problems referred to above is at the lens upper and lower protective glass to be installed again.But also can often in use being damaged, protective glass needs frequent.
Summary of the invention
For the problems referred to above, the invention provides the laser soldering device that carries the protection facility, it can protect laser radiation equipment, and its high temperature chip that can not be splashed is damaged, and has prolonged equipment life.
The technical solution adopted in the present invention is: it comprises the laser soldering device body; described laser soldering device body comprises protection gas blowout stream device; described laser soldering device body below is equipped with protective glass, it is characterized in that: described protective glass below is provided with splash-back.
It is further characterized in that: be provided with jet apparatus between described splash-back and the described protective glass, described jet apparatus comprises the jet flow bracing frame, is provided with flow jeting port on the support frame as described above, and described flow jeting port is connected with compressed air hose; Be provided with thermal insulation board between described jet apparatus and the described protective glass, described heat-proof device is connected with protection gas blowout stream device.
After adopting design of the present invention, when carrying out laser weld, the high-temperature metal chip that splashes is blocked in splash-back, and the jet apparatus on the splash-back stops the chip that is not blocked by splash-back to continue upwards to be splashed on the protective glass towards the below gas transmission.Arranging of thermal insulation board will prevent that the amount of heat that welds generation from damaging laser soldering device, and the protection device of air of connection then can prevent that it is subjected to high temperature generation oxidation to equipment protection.
