DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, purposes and effects of the present application easy to understand, the present application is further described below in combination with specific embodiments.

[0032] Combination Figure 1 And Figure 2 As shown in the figure, the laser welding device for lamp metal frame of the embodiment of the present application comprises a bottom leg 1, the top of the bottom leg 1 is fixedly connected with a mounting seat 2, the horizontal direction of the upper surface of the mounting seat 2 is slidably connected with a limit plate one 3, the front and back direction of the upper surface of the mounting seat 2 is slidably connected with a limit plate two 4, the back of the back of the mounting seat 2 is provided with a welding table 5, the top of the welding table 5 is provided with a laser welding head 6, the inner cavity of the mounting seat 2 is rotatably connected with a driving shaft one 7 and a driving shaft two 8, the inner cavities of the driving shaft one 7 and the driving shaft two 8 are respectively threadedly connected with the limit plate one 3 and the limit plate two 4, the lower surface of the mounting seat 2 is fixedly connected with a gas storage tank 9, the inner side walls of the limit plate one 3 and the limit plate two 4 are respectively provided with a chuck 10 and a locking part 11, the outer periphery of the driving shaft one 7 is provided with a welding fume assembly, the welding fume assembly is used for protecting and treating the welding fume generated by the welded lamp metal frame workpiece;

[0033] When the lamp metal frame workpiece needs to be welded, the lamp metal frame workpiece is first clamped, the limiting plate one 3 and the limiting plate two 4 are adjusted according to the required size of the lamp metal frame workpiece, the size of the lamp metal frame workpiece is determined, the drive shaft one 7 is energized and rotates along the internal thread of the mounting seat 2, the limiting plate one 3 gradually moves from the side to the middle position on the upper surface of the mounting seat 2 under the action of the threaded transmission, and the limiting plate two 4 gradually moves to the middle position under the action of the threaded transmission of the drive shaft two 8, the limiting plate two 4 and the limiting plate one 3 are close to each other, and stop until the lamp metal frame workpiece is adjusted to the appropriate size position, at this time the lamp metal frame workpiece is clamped between the clamp head 10 and the lock piece 11, at this time the laser welding head 6 is started to perform laser welding, and the lamp metal frame workpiece is welded with the movement of the laser welding head 6, so that the lamp metal workpiece has stable and accurate welding effect.

[0034] After welding, the metal material of the lamp metal frame workpiece will generate a lot of welding smoke when welded by the laser welding head 6, and the welding smoke inside will cause harm to the human body, and the laser welding head 6 is used to weld the lamp metal frame workpiece, and the drive shaft one 7 and the drive shaft two 8 are reworked, at this time the drive shaft one 7 and the drive shaft two 8 drive the limiting plate two 4 and the limiting plate one 3 to move away from each other, and the workpiece is loosened, and the welding smoke assembly is driven to work when the drive shaft one 7 rotates, the water mist dust suppression solution is sprayed by the rotating force of the drive shaft one 7 according to the physical extrusion mode, the water mist dust suppression solution adsorbs the welding smoke particles, and makes them settle in the gas storage tank 9, thereby reducing the suspended welding smoke particles in the air; It should be noted that one end of the drive shaft one 7 and the drive shaft two 8 is externally connected with a motor, and the output end of the motor is connected with the drive shaft one 7 and the drive shaft two 8; the welding table 5 is used to support the laser welding head 6.

[0035] As Figures 7 to 8 , Figure 11As shown, the welding fume assembly includes a support frame 71 mounted on the outer periphery of the drive shaft 7. A lever 73 is rotatably connected to the top inner cavity of the support frame 71. A belt 72 is attached to one end of the lever 73. A sling 74 is fixedly connected to the outer surface of the end of the lever 73. An air pump 75 is located at the bottom of the sling 74. Two transmission pipes 76 are inserted into the lower surface of the air pump 75. A storage container is installed on the inner wall of each transmission pipe 76, containing a water mist dust suppression solution. Spray columns 77 are located at the bottom ends of the two transmission pipes 76, and the spray columns 77 interact with the water mist dust suppression solution. The dust and solution are connected. A spring 78 is provided in the middle of the spray column 77, and a push plate 79 is fixedly connected to the end of the spring 78. The spray column 77 has evenly distributed slots on the side near the push plate 79. The slots are used to blow out gas to push the push plate 79 to move. The belt 72 is sleeved between the drive shaft 7 and the actuating rod 73. The actuating rod 73 passes through the interior of the support frame 71. The spray column 77 is provided with a buckle that matches the push plate 79, so that the push plate 79 and the spray column 77 can be combined into one in the initial state.

[0036] When welding fume treatment is required during operation, using this embodiment of the invention, the drive shaft 7 is energized and rotates, driving the belt 72 to move. The belt 72 drives the actuating lever 73 to rotate. After the actuating lever 73 rotates, it intermittently contacts the air pump 75 switch through the swing bar 74, gradually activating the air pump 75. The air from the air pump 75 rushes into the transmission pipe 76, breaking through the water mist dust suppression solution on the inner wall of the transmission pipe 76 and spraying it out through the spray column 77. After the water mist dust suppression solution is sprayed out, it adsorbs the welding fume. It should be noted that the push plate 79 can be made of lightweight material to ensure that the force of the water mist dust suppression solution sprayed out can push the push plate 79, so that the push plate 79... After detaching from the spray column 77, the push plate 79 scrapes along the upper surface of the mounting base 2, which helps to clean the small particles generated by welding fumes on the upper surface of the mounting base 2, and ultimately facilitates the entry of welding fumes into the gas storage box 9, improving the usage effect. It should be noted that the air pump 75 is located outside the limiting plate 3, and the length of the air pump 75 will not hinder the movement of the limiting plate 3. The weight of the push plate 79 is less than the force of the spray column 77. The spray direction of the spray column 77 is tilted at 45 degrees, and the sprayed water mist dust suppression solution is located at the exact center of the lamp metal frame workpiece. The lamp metal frame workpiece does not come into contact with the water mist dust suppression solution and will not affect the welding effect.

[0037] like Figures 9 to 10 As shown, the push plate 79 includes a toggle assembly on its side. The toggle assembly is used to push the particles included in the welding fume into the gas storage box 9. The toggle assembly includes a shovel 791. A clamping plate 792 is fixedly connected to the lower surface of the shovel 791. A plurality of toggle elements 793 are provided at the bottom end of the clamping plate 792. The end of the shovel 791 is flush with the upper surface of the mounting base 2 to facilitate better scraping of the upper surface of the mounting base 2. The toggle elements 793 are made of rubber.

[0038] In operation, during the scraping process of the pushing plate 79 along the upper surface of the mounting base 2, since the direction of the force of the pushing plate 79 is linear, the particles will accumulate at a certain position on the upper surface of the mounting base 2, and when falling into the gas storage tank 9, part of the particles will remain on the upper surface, and the scraping is not clean enough. By using the embodiment of the application, when the pushing plate 79 moves, the shovel blade 791 and the clamping plate 792 will move synchronously, the shovel blade 791 removes the particles, the particles move above the shovel blade 791, the bottom of the clamping plate 792 gradually contacts the upper surface of the mounting base 2 to produce swing, and the residual particles are rubbed again during the swing and rubbing, and the cleanliness of the upper surface of the mounting base 2 is further improved; when the shovel blade 791 is pushed to the limit position, the shovel blade 791 retreats to gradually scatter the particles, and finally the suction force generated in the subsequent gas storage tank 9 is used to complete the collection.

[0039] As shown in Figures 3 to 4 The side of the limiting plate one 3 is provided with a turnover assembly, the turnover assembly is used for turnover processing of the lamp metal frame workpiece, the turnover assembly comprises a supporting block 31 mounted on the upper surface of the mounting base 2, the supporting block 31 and the limiting plate one 3 are matched in size, a rotating cylinder 32 is rotatably connected in the inner cavity of the supporting block 31, an indicating part 33 is arranged on the outer surface of the rotating cylinder 32, two grooves are formed in the inner side wall of the supporting block 31, an electric sliding block 34 is slidably connected in the grooves, and a lifting plate 35 is fixedly connected to the bottom end of the electric sliding block 34; a processor is arranged at the end of the rotating cylinder 32, the processor is used for receiving and executing the electric signal of the movement of the electric sliding block 34, a suction disc is arranged at the end of the rotating cylinder 32, and an inductor is arranged in the indicating part 33, the inductor is used for reminding the raised standard position.

[0040] When welding the other side of the lamp metal frame workpiece, the manual turning method is inconvenient and the protection is not timely, which may cause damage, but when the lamp metal frame workpiece is welded on one side, the device receives the signal that the laser welding head 6 welds one side, and transmits the signal to the processor, the electric sliding block 34 is driven upward by the processor, the electric sliding block 34 drives the lifting plate 35 to move upward along the two grooves formed in the inner side wall of the supporting block 31, the lifting plate 35 lifts the lamp metal frame workpiece upward, at this time, the lamp metal frame workpiece is separated from the clamping head 10 and the locking piece 11, when the lamp metal frame workpiece moves upward to the position of the indicating piece 33, the suction cup of the rotating cylinder 32 adsorbs it, and the rotating cylinder 32 rotates after receiving the sensing signal, and then slowly puts the lamp metal frame workpiece back into the clamping head 10 and the locking piece 11, thereby completing the automatic turning effect and improving the safety of operation; it should be noted that in actual production, the suction force of the rotating cylinder 32 is sufficient to support the weight of the metal frame, so as to avoid the situation that the metal frame is too heavy and the suction cup cannot be adsorbed.

[0041] As shown in Figure 6 The outer surface of the gas storage tank 9 is provided with a smoke exhaust assembly, the smoke exhaust assembly comprises a suction pump 91 mounted on the outer side of the gas storage tank 9, an exhaust pipe 92 is mounted on the side of the gas storage tank 9, a filter layer 93 is arranged at the inner cavity of the gas storage tank 9, a guide rod 94 is arranged at the top of the filter layer 93, the guide rod 94 penetrates through the inside of the filter layer 93, a dismounting disc 95 is movably connected to the top of the guide rod 94, and the bottom end of the guide rod 94 is fixedly connected with the gas storage tank 9. The exhaust pipe 92 is located below the filter layer 93.

[0042] When it is necessary to filter, collect and process welding smoke, the embodiment of the application is used, before welding, the suction pump 91 is driven to rotate, the suction pump 91 rotates to adsorb the welding smoke upward, during the laser welding process, the welding smoke is gradually sucked into the gas storage tank 9 through the holes in the upper surface of the mounting seat 2, and the filter layer 93 filters the welding smoke, and finally the welding smoke is discharged from the exhaust pipe 92.

[0043] When the suction pump 91 rotates, the welding smoke above is strongly sucked into the gas storage tank 9, and the residual particles on the inclined surface of the shovel piece 791 are accelerated to enter the gas storage tank 9 along with the suction force, so that the effect of cleaning the upper surface of the mounting seat 2 is improved.

[0044] Working principle: first, the lamp metal frame workpiece is clamped, according to the size of the lamp metal frame workpiece needs to adjust the limit plate 3 and limit plate 4, determine the size of the lamp metal frame workpiece, drive shaft 7 power along the inside thread of mounting seat 2 rotation, under the action of screw drive limit plate 3 gradually along the mounting seat 2 upper surface from the side to the middle position, similarly, under the action of screw drive drive shaft 8, limit plate 4 gradually to the middle position, limit plate 4 and limit plate 3 two mutual approach, until the appropriate size of the lamp metal frame workpiece position stop, at this time the lamp metal frame workpiece is clamped between the chuck 10 and lock 11, at this time the lamp metal frame workpiece is clamped, at this time down limit plate 3, limit plate 3 is inserted into the lower part of the mounting seat 2 cavity, at this time the drive shaft 7 and limit plate 3 lose the action of screw drive, stop motor, start laser welding head 6 again to carry on the laser welding, with the movement of laser welding head 6 on the lamp metal frame workpiece welding, so as to ensure the lamp metal workpiece has stable welding precision effect;

[0045] In the process of welding, due to the metal material of the lamp metal frame workpiece and the laser welding head 6 welding treatment will produce more welding fume, and the welding fume inside with small debris particles will cause harm to human body, after the laser welding head 6 welding on the lamp metal frame workpiece, the drive shaft 7 works again, the drive shaft 7 rotates will drive the welding fume assembly work, the welding fume assembly works through the rotation of drive shaft 7 according to the physical extrusion way to spray water mist dust suppression solution, water mist dust suppression solution adsorbs welding fume particles, makes it settle in the gas storage tank 9, and further reduces the suspended welding fume particles in the air; It should be noted that the one end of drive shaft 7 and drive shaft 8 is connected with motor, and the output end of motor is connected with drive shaft 7 and drive shaft 8; The welding table 5 is used for supporting the laser welding head 6;

[0046] When the lamp metal frame workpiece one side welding is completed, the device receives the signal of laser welding head 6 welding one side, and transmits the signal to the processor, the processor drives the electric sliding block 34 to work upward, the electric sliding block 34 drives the lifting plate 35 to move upward along the two grooves in the inner side wall of the support block 31, the lifting plate 35 lifts the lamp metal frame workpiece, at this time the lamp metal frame workpiece is separated from the chuck 10 and the lock 11, when the lamp metal frame workpiece moves to the position of the indicating part 33, the suction cup of the rotating cylinder 32 adsorbs it, and the rotating cylinder 32 rotates after receiving the sensing signal, the rotating cylinder 32 rotates one circle and then slowly puts the lamp metal frame workpiece into the chuck 10 and the lock 11 again, so as to complete the automatic turning effect and improve the safety of operation; It should be noted that in actual production process, the suction force of rotating cylinder 32 is enough to support the weight of metal frame, so as to avoid the situation that the metal frame is too heavy to be adsorbed by the suction cup.

[0047] The foregoing merely illustrates the principles of the application and application of its more prominent features. Those skilled in the art will appreciate that the application is not limited to the embodiments described and illustrated and that many changes and modifications will occur to them without departing from the spirit and scope of the present application. The present application is therefore not to be limited to the exact details shown and described but only by the scope of the appended claims.
