DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0032] Combination Figure 1 and Figure 2 As shown, a laser welding device for a metal frame of a lamp described in an embodiment of the present invention comprises a bottom leg 1, a mounting seat 2 is fixedly connected to the top of the bottom leg 1, a limit plate 3 is slidably connected to the upper surface of the mounting seat 2 in the horizontal direction, a limit plate 2 is slidably connected to the upper surface of the mounting seat 2 in the front-rear direction, a welding table 5 is arranged at the rear of the back of the mounting seat 2, a laser welding head 6 is arranged at the top of the welding table 5, a driving shaft 1 7 and a driving shaft 2 8 are rotatably connected at the inner cavity of the mounting seat 2, and the limit plate 1 3 and the limit plate 2 4 are respectively threadedly connected at the inner cavities of the driving shaft 1 7 and the driving shaft 2 8, an air storage box 9 is fixedly connected to the lower surface of the mounting seat 2, a clamp 10 and a lock 11 are arranged on the inner side walls of the limit plate 1 3 and the limit plate 2 4, a welding smoke assembly is installed at the periphery of the driving shaft 7, and the welding smoke assembly is used to protect the welding smoke generated by the welding of the metal frame of the lamp;

[0033] During operation, when it is necessary to perform welding on the metal frame workpiece of the lamp, the embodiment of the present invention is used to first clamp the metal frame workpiece of the lamp, adjust the limit plate 1 3 and the limit plate 2 4 according to the required size of the metal frame workpiece of the lamp, and after determining the size of the metal frame workpiece of the lamp, the driving shaft 1 7 is energized to rotate along the internal thread of the mounting seat 2, and the limit plate 1 3 gradually moves from the side to the middle position along the upper surface of the mounting seat 2 under the action of the thread transmission. Similarly, under the thread transmission action of the driving shaft 2 8, the limit plate 2 4 gradually moves to the middle position, and the limit plate 2 4 and the limit plate 1 3 move closer to each other until they are adjusted to a suitable size position of the metal frame workpiece of the lamp and stop. At this time, the metal frame workpiece of the lamp is clamped between the clamping head 10 and the locking piece 11, and the laser welding head 6 is started to perform laser welding on it. As the laser welding head 6 moves, the metal frame workpiece of the lamp is welded, thereby ensuring that the metal workpiece of the lamp has a stable and accurate welding effect;

[0034] After welding is completed, a lot of welding smoke will be generated during the welding process between the metal material of the metal frame workpiece of the lamp and the laser welding head 6, and the welding smoke is accompanied by fine debris particles, which will cause harm to the human body. After the laser welding head 6 welds the metal frame workpiece of the lamp, the drive shaft 1 7 and the drive shaft 2 8 are made to work again. At this time, the drive shaft 1 7 and the drive shaft 2 8 respectively drive the limit plate 2 4 and the limit plate 1 3 to move away from each other, loosen the workpiece, and when the drive shaft 1 7 rotates, it will drive the welding smoke component to work. When the welding smoke component is working, the water mist dust suppression solution is sprayed out by the rotation force of the drive shaft 1 7 according to the physical extrusion method. The water mist dust suppression solution absorbs the welding smoke particles and makes them settle in the air storage box 9, thereby reducing the welding smoke particles suspended in the air; it should be noted that one end of the drive shaft 1 7 and the drive shaft 2 8 are both externally connected to a motor, and the output end of the motor is connected to the drive shaft 1 7 and the drive shaft 2 8; the welding table 5 is used to support the laser welding head 6.

[0035] like Figures 7 and 8 , Fig.11As shown, the welding smoke assembly includes a support frame 71 installed on the periphery of a driving shaft 7, the top inner cavity of the support frame 71 is rotatably connected to a toggle rod 73, one end of the toggle rod 73 is provided with a belt 72, the outer surface of the end of the toggle rod 73 is fixedly connected to a swing bar 74, the bottom of the swing bar 74 is provided with an air pump 75, the lower surface of the air pump 75 is plugged with two transmission pipes 76, the inner wall of the transmission pipe 76 is installed with a storage part, the storage part contains a water mist dust suppression solution, the bottom ends of the two transmission pipes 76 are provided with spray columns 77, and the spray columns 77 are connected to the water mist dust suppression solution. The dust solution is connected, a spring member 78 is arranged in the middle of the spray column 77, and a push plate 79 is fixedly connected to the end of the spring member 78; the spray column 77 is provided with evenly distributed notches on one side close to the push plate 79, and the notches are used to blow out the gas to push the push plate 79 to move, the belt 72 is sleeved between the drive shaft 7 and the toggle rod 73, and the toggle rod 73 runs through the interior of the support frame 71; the spray column 77 is provided with a buckle adapted to the push plate 79, so as to facilitate the push plate 79 and the spray column 77 to be combined into one in the initial state.

[0036] During operation, when welding smoke treatment is required, the embodiment of the present invention is used, the drive shaft 7 is powered on and rotated to drive the belt 72 to move, the belt 72 drives the toggle lever 73 to rotate, and after the toggle lever 73 rotates, it intermittently contacts the switch of the air pump 75 through the swing bar 74, and the air pump 75 gradually works, and the gas of the air pump 75 rushes into the interior of the transmission pipe 76, and the water mist dust suppression solution on the inner wall of the transmission pipe 76 is broken and sprayed out through the spray column 77. After the water mist dust suppression solution is sprayed out, it absorbs the welding smoke. It should be noted that the push plate 79 can be made of lightweight material to ensure that the impact of the spray of the water mist dust suppression solution can push the push plate 79, so that the push plate 79 Disengage from the spray column 77, and push the plate 79 to scrape along the upper surface of the mounting seat 2, which is beneficial to cleaning the small particles generated by welding smoke on the upper surface of the mounting seat 2, and finally facilitate the welding smoke to enter the air storage box 9, thereby improving the use effect; it should be noted that the air pump 75 is located on the outside of the limit plate 3, and the length of the air pump 75 will not hinder the movement of the limit plate 3; the weight of the push plate 79 is less than the force of the spray of the spray column 77; the spray direction of the spray column 77 is inclined at forty-five degrees, and the sprayed water mist dust suppression solution is located at the center of the metal frame workpiece of the lamp, and the metal frame workpiece of the lamp does not contact the water mist dust suppression solution, which will not affect the welding effect.

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

[0038] During operation, when the push plate 79 is scraping along the upper surface of the mounting seat 2, since the direction of the force of the push plate 79 is a linear direction, particles will accumulate at a certain place on the upper surface of the mounting seat 2, and some of them will remain on the upper side when falling into the air storage box 9, resulting in the problem of insufficient scraping. When using the embodiment of the present invention, when the push plate 79 moves, the shovel blade 791 and the card plate 792 will move synchronously, and the shovel blade 791 will scrape the particles, and the particles will move above the shovel blade 791. The toggle member 793 at the bottom of the card plate 792 will gradually contact the upper surface of the mounting seat 2 and swing. When toggling, the remaining particles will be rubbed again. Under the action of swinging and friction, the cleanliness of the upper surface of the mounting seat 2 will be improved. When the shovel blade 791 is pushed to the limit position, the shovel blade 791 retreats to scatter the particles little by little, and finally completes the collection with the suction force generated in the subsequent air storage box 9.

[0039] like Figure 3 to Figure 4 As shown, a flip assembly is provided on the side of the limit plate 3, and the flip assembly is used to flip the metal frame workpiece of the lamp, and the flip assembly includes a support block 31 installed on the upper surface of the mounting seat 2, and the specifications and sizes of the support block 31 and the limit plate 3 are adapted to each other, and a rotating cylinder 32 is rotatably connected to the inner cavity of the support block 31, and an indicator 33 is provided on the outer surface of the rotating cylinder 32, and two grooves are provided on the inner side wall of the support block 31, and an electric slider 34 is slidably connected in the groove, and a lifting plate 35 is fixedly connected to the bottom end of the electric slider 34; a processor is provided at the end of the rotating cylinder 32, and the processor is used to receive and execute the electrical signal of the movement of the electric slider 34, and a suction cup is provided at the end of the rotating cylinder 32, and a sensor is provided inside the indicator 33, and the sensor is used to remind the standard position of the rise;

[0040] During operation, after laser welding one side of the metal frame of the lamp is completed, the other side needs to be welded. At this time, it is inconvenient to manually turn it over, and it is easy to be damaged due to untimely protection. Using the embodiment of the present invention, when the welding of one side of the metal frame of the lamp is completed, the equipment receives a signal from the laser welding head 6 that one side has been welded, and transmits the signal to the processor. The processor drives the electric slider 34 to work upward, and the electric slider 34 drives the lifting plate 35 to move upward along the two grooves provided on the inner wall of the support block 31. The lifting plate 35 lifts the metal frame of the lamp upward. At this time, the metal frame workpiece of the lamp is separated from the clamping head 10 and the locking piece 11. When the metal frame workpiece of the lamp moves upward to the position of the indicator 33, the suction cup of the rotating cylinder 32 adsorbs it, and the rotating cylinder 32 rotates after receiving the sensing signal. After the rotating cylinder 32 rotates one circle, the metal frame workpiece of the lamp is slowly put back between the clamping head 10 and the locking piece 11, thereby completing the automatic turning over effect and improving the safety of operation. It should be noted that in the actual production process, the suction force of the rotating cylinder 32 is sufficient to support the weight of the metal frame to avoid the situation where the metal frame is too heavy and the suction cup cannot adsorb it.

[0041] like Figure 6 As shown, a smoke exhaust assembly is provided on the outer surface of the air storage box 9, and the smoke exhaust assembly includes an exhaust pump 91 installed on the outside of the air storage box 9, an exhaust pipe 92 is installed on the side of the air storage box 9, and a filter layer 93 is provided in the inner cavity of the air storage box 9. A guide rod 94 is provided on the top of the filter layer 93, and the guide rod 94 passes through the interior of the filter layer 93. A disassembly disk 95 is movably connected to the top of the guide rod 94, and the bottom end of the guide rod 94 is fixedly connected to the air storage box 9, and the exhaust pipe 92 is located below the filter layer 93.

[0042] During operation, when it is necessary to filter, collect and process welding smoke, the embodiment of the present invention is used. Before welding, the exhaust pump 91 is driven to rotate. The exhaust pump 91 rotates to absorb the welding smoke from above downward. During the laser welding process, the exhaust pump 91 rotates, and the welding smoke gradually passes through the holes on the upper surface of the mounting seat 2 and enters the air storage box 9 downward. The filter layer 93 filters it and finally discharges it from the exhaust pipe 92 after filtering.

[0043] When the exhaust pump 91 rotates, the welding smoke above will be forcefully sucked into the air storage box 9, and the residual particles poured out by the inclined surface of the shovel blade 791 will be accelerated into the air storage box 9 by the suction force, thereby facilitating the improvement of the effect of cleaning the upper surface of the mounting base 2.

[0044] Working principle: First, position the metal frame of the lamp, adjust the limit plate 1 3 and the limit plate 2 4 according to the required size of the metal frame of the lamp, and after determining the size of the metal frame of the lamp, energize the drive shaft 1 7 and rotate along the internal thread of the mounting seat 2. Under the action of the thread transmission, the limit plate 1 3 gradually moves from the side to the middle position along the upper surface of the mounting seat 2. Similarly, under the action of the thread transmission of the drive shaft 2 8, the limit plate 2 4 gradually moves to the middle position, and the limit plate 2 4 and the limit plate 1 3 move closer to each other until they are adjusted to The lamp metal frame workpiece stops at a suitable size position, and the lamp metal frame workpiece is clamped between the clamp head 10 and the lock 11. At this time, the lamp metal frame workpiece is clamped, and the limit plate 3 is pressed down, and the limit plate 3 is inserted to the bottom of the inner cavity of the mounting seat 2. At this time, the drive shaft 7 and the limit plate 3 lose the function of thread transmission, stop the motor, and then start the laser welding head 6 to perform laser welding on it. As the laser welding head 6 moves, the lamp metal frame workpiece is welded, thereby ensuring that the lamp metal workpiece has a stable and accurate welding effect;

[0045] During the welding process, a lot of welding smoke will be generated when the metal material of the metal frame of the lamp is welded with the laser welding head 6, and the welding smoke is accompanied by fine debris particles, which will cause harm to the human body. After the laser welding head 6 welds the metal frame of the lamp, the drive shaft 7 is driven to work again. When the drive shaft 7 rotates, it will drive the welding smoke component to work. When the welding smoke component is working, the water mist dust suppression solution is sprayed out by physical extrusion through the rotation force of the drive shaft 7. The water mist dust suppression solution absorbs the welding smoke particles and makes them settle in the air storage box 9, thereby reducing the welding smoke particles suspended in the air; it should be noted that one end of the drive shaft 1 7 and the drive shaft 2 8 are both externally connected to a motor, and the output end of the motor is connected to the drive shaft 1 7 and the drive shaft 2 8; the welding table 5 is used to support the laser welding head 6;

[0046] When one side of the metal frame workpiece of the lamp is welded, the device receives a signal that the laser welding head 6 has completed welding one side, and transmits the signal to the processor, the processor drives the electric slider 34 to work upward, the electric slider 34 drives the lifting plate 35 to move upward along the two grooves opened on the inner wall of the support block 31, the lifting plate 35 lifts the metal frame workpiece of the lamp upward, at this time the metal frame workpiece of the lamp is separated from the clamping head 10 and the locking piece 11, when the metal frame workpiece of the lamp moves upward to the position of the indicator 33, the suction cup of the rotating cylinder 32 adsorbs it, and the rotating cylinder 32 rotates after receiving the sensing signal, and the rotating cylinder 32 rotates one circle and then slowly puts the metal frame workpiece of the lamp back between the clamping head 10 and the locking piece 11, thereby completing the effect of automatic turning over and improving the safety of operation; it should be noted that in the actual production process, the suction force of the rotating cylinder 32 is sufficient to support the weight of the metal frame to avoid the situation where the metal frame is too heavy and the suction cup cannot adsorb it.
