Description

Technical Field

[0001] The present invention relates to the technical field of laser welders, and in particular to a new material servo laser welder. Background Art

[0002] The servo laser welder is a high-precision welding equipment that uses a servo motor to precisely control the motion trajectory and welding parameters of the laser head to achieve an efficient and stable welding process. Its core advantages lie in high dynamic response and precise positioning, making it suitable for the processing of complex welds and microstructures. In response to the welding needs of new materials (such as high-strength aluminum alloys, titanium alloys, composite materials, etc.), the servo laser welder effectively solves defects such as thermal cracks and pores through technologies such as tunable laser wavelength, multi-beam collaboration, and real-time temperature monitoring. In addition, its intelligent system can adaptively adjust power, frequency, and scanning speed to ensure weld uniformity and strength. It is widely used in aerospace, new energy batteries, 3C electronics, and other fields, promoting the innovation and upgrading of new material welding processes.

[0003] Traditional servo laser welders may generate some polluted gases or harmful particles when welding new materials. Generally, the polluted gases are treated by a heat dissipation motor and a filter cartridge. However, this treatment method cannot recycle some metal vapors, resulting in reduced metal utilization. At the same time, metal vapors will increase the filtering burden of the filter cartridge.

Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention. Furthermore, in actual production, the three-dimensional dimensions of length, width, and depth should be included.

[0032] Example 1

[0033] Reference Figure 1-4 , as the first embodiment of the present invention, provides a new material servo laser welding machine, the device includes,

[0034] The welding mechanism 100 includes a laser welder body 110, a welding head 120 mounted on the laser welder body 110 and used for welding new materials, a protective box 130 fixedly mounted on the top of the laser welder body 110 and located directly below the welding head 120, and a connecting cover 140 fixedly mounted on the protective box 130 and moving with the welding head 120.

[0035] The purification and recovery mechanism 200 includes a filter component 210 for purifying polluted gases and harmful particles generated during welding, a recovery component 220 for recovering condensed metal vapor, and a cooling component 230 for cooling the workpiece after welding.

[0036] Among them, through the cooperation between the filtering component 210 and the recovery component 220, the polluted gas and metal vapor generated during the welding process of the new material are processed and recovered, thereby solving the problem that the traditional servo laser welder cannot recover the metal vapor when processing the polluted gas, thereby reducing the utilization rate of the metal; the cooling component 230 is used to cool the new material with the help of the power of the polluted gas treatment, thereby improving the cooling efficiency of the new material after welding.

[0037] Specifically, the filter component 210 includes a filter cartridge 211 connected to the protective box 130 and used to filter and purify polluted gases and harmful particles, an exhaust pipe 212 connected to the other end of the filter cartridge 211, and a ventilation motor 213 arranged inside the exhaust pipe 212 and used to discharge the air inside the protective box 130.

[0038] Among them, when the welding head 120 welds new materials, polluted gases and harmful particles may be generated. Under the action of the ventilation motor 213, the air inside the protective box 130 is extracted. When the extracted air passes through the filter cartridge 211, the filter cartridge 211 filters and processes the polluted gases and harmful particles, and then discharges them through the exhaust pipe 212, thereby purifying the polluted gases and harmful particles generated by the welding of new materials, and avoiding direct discharge into the air, which affects the health of workers.

[0039] Furthermore, a fixing ring 214 for fixing the exhaust pipe 212 is fixedly installed on the side of the laser welding machine body 110 , and the fixing ring 214 is sleeved on the surface of the exhaust pipe 212 .

[0040] The fixing ring 214 is used to reinforce the exhaust pipe 212 , thereby improving the installation stability of the exhaust pipe 212 .

[0041] During use, when the welding head 120 welds new materials, polluted gases and harmful particles may be generated. The air inside the protective box 130 is extracted under the action of the ventilation motor 213. When the extracted air passes through the filter cartridge 211, the filter cartridge 211 filters and processes the polluted gases and harmful particles, and then discharges them through the exhaust pipe 212, thereby purifying the polluted gases and harmful particles generated by the welding of new materials.

[0042] In summary, through the cooperation between the filtering component 210 and the recovery component 220, the polluted gas and metal vapor generated during the welding process of new materials are treated and recovered, thereby solving the problem that traditional servo laser welders cannot recover metal vapor when treating polluted gases, thereby reducing the utilization rate of metal.

[0043] Example 2

[0044] Reference Figure 1-5 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the recovery component 220 includes a box body 221 connected between the protection box 130 and the filter cartridge 211, a sealing cover plate 222 arranged on the top of the box body 221, a plurality of quenching plates 223 fixedly installed at an angle on the bottom of the sealing cover plate 222 and used for condensing metal vapor, and ventilation grooves 224 respectively opened on the top and bottom of adjacent quenching plates 223 and used for gas flow.

[0045] Among them, when the welding head 120 welds new materials, polluted gases and harmful particles may be generated. Under the action of the ventilation motor 213, the air inside the protective box 130 is extracted. When the air passes through the inside of the box body 221, it will flow along the quench plate 223 and flow out through the ventilation groove 224, making the air flow serpentine. When the metal vapor passes through the surface of the quench plate 223, the quench plate 223 condenses the metal vapor, so that the metal particles adhere to the surface of the quench plate 223, so as to achieve the recovery of the metal particles.

[0046] Specifically, a connecting plate 225 is fixedly installed between the quenching plates 223 , and the connecting plate 225 is used to connect the quenching plates 223 to form a whole.

[0047] The connecting plate 225 is used to connect several quenching plates 223 to form a whole, which is convenient for installation and disassembly. At the same time, the connecting plate 225 is the necessary place for the pipelines between the quenching plates 223 to pass through.

[0048] Furthermore, a collecting plate 226 for collecting metal particles is fixedly installed on the windward surface of the quenching plate 223, and the collecting plate 226 is arranged to be inclined upward.

[0049] The collecting plate 226 is used to collect the metal particles that are not attached to the surface of the quenching plate 223 , so as to prevent the metal particles from falling into the interior of the box 221 and being inconvenient to collect.

[0050] Preferably, the interior of the quench plate 223 is provided with a pipeline for cooling, and the top of the sealing cover plate 222 is provided with an inlet pipe 227 and a return pipe 228 for water inlet and outlet, respectively. The inlet pipe 227 and the return pipe 228 are respectively connected to the ends of the pipeline, and the pipeline between the quench plates 223 passes through the interior of the connecting plate 225.

[0051] Among them, the water inlet pipe 227 is used to drain and guide the coolant into the pipeline inside the quench plate 223. When the coolant passes through the pipeline, the quench plate 223 will be quickly cooled, so that when the metal vapor passes through the surface of the quench plate 223, the metal vapor will condense on the surface of the quench plate 223, which can realize the recovery of the metal vapor and improve the utilization rate of the metal, especially the precious metal. Finally, the coolant returns to the cooling equipment through the return pipe 228.

[0052] Furthermore, a reserved groove 229 is provided on the top of the box body 221 for use with the sealing cover plate 222 , and the sizes of the sealing cover plate 222 and the reserved groove 229 are adapted to each other.

[0053] Among them, the reserved groove 229 is used to cooperate with the installation of the sealing cover plate 222. There is friction between the side of the sealing cover plate 222 and the inner wall of the reserved groove 229, so that the sealing cover plate 222 is clamped inside the reserved groove 229, thereby improving the use stability of several quenching plates 223, and at the same time facilitating the removal of the quenching plates 223 from the inside of the box body 221, and recovering the metal particles attached to the surface of the quenching plate 223 or falling on the collection plate 226.

[0054] During use, when the welding head 120 welds new materials, polluted gases and harmful particles may be generated. The air inside the protective box 130 is extracted under the action of the ventilation motor 213. When the air passes through the inside of the box body 221, it will flow along the quench plate 223 and flow out through the ventilation groove 224, making the air flow serpentine. When the metal vapor passes through the surface of the quench plate 223, the quench plate 223 condenses the metal vapor, so that the metal particles adhere to the surface of the quench plate 223.

[0055] In summary, through the cooperation between the filtering component 210 and the recovery component 220, the polluted gas and metal vapor generated during the welding process of new materials are treated and recovered, thereby solving the problem that traditional servo laser welders cannot recover metal vapor when treating polluted gases, thereby reducing the utilization rate of metal.

[0056] Example 3

[0057] Reference Figure 1 、 Figure 2 and Figure 6 , which is the third embodiment of the present invention. This embodiment differs from the second embodiment in that: the cooling component 230 includes a hollow plate 231 disposed inside the protective box 130, a plurality of air outlet nozzles 232 disposed on the top of the hollow plate 231 and used to cool the new material, a plurality of air guide pipes 233 connected to one side of the hollow plate 231, and a filter box 234 fixedly installed on one side of the protective box 130 and used for air filtering;

[0058] The other end of the air guide pipe 233 is communicated with the interior of the filter box 234 .

[0059] Among them, the air in the protective box 130 is discharged through the exhaust pipe 212, and the external air is then filtered through the filter box 234 and introduced into the air guide pipe 233. The air flows into the interior of the hollow plate 231 along the air guide pipe 233, and is then discharged from a number of air outlet nozzles 232. The air is blown to the surface of the new material to cool it, so as to prevent the ultra-thin new material from being easily burned through due to heat accumulation, resulting in the scrapping of the material.

[0060] Specifically, a support block 150 for supporting and limiting the new material is fixedly installed on the top of the laser welding machine body 110 . The support block 150 is located inside the protective box 130 , and the hollow plate 231 is located on the inner side of the support block 150 .

[0061] Among them, a number of support blocks 150 are used to support and fix the new material to be welded, thereby improving the welding stability of the new material.

[0062] During use, the air in the protective box 130 is discharged through the exhaust pipe 212, and the external air is then filtered through the filter box 234 and introduced into the air guide pipe 233. The air flows along the air guide pipe 233 into the interior of the hollow plate 231, and is then discharged from several air outlet nozzles 232, and the air is blown onto the surface of the new material to cool it.

[0063] In summary, the cooling component 230 is used to cool the new material with the power of treating the polluted gas, thereby improving the cooling efficiency of the new material after welding.
