[0001] The utility model relates to the technical field of welding workstations, in particular to a smoke and dust processing type large-scale robot welding workstation. Background Art

[0002] A robot is an automated machine. The difference is that this machine has some intelligent capabilities similar to humans or living things, such as perception, planning, movement and coordination. It is an automated machine with high flexibility. Robots can assist or even replace humans in completing dangerous, heavy and complex tasks, improve work efficiency and quality, serve human life, and expand and extend the scope of human activities and capabilities.

[0003] When robots are produced or repaired, their parts need to be welded and assembled. Currently, the welding work of small robots is generally carried out on a carrier, while that of large robots is carried out in a welding workstation. Most of the existing welding workstations are not equipped with a smoke treatment structure, which makes it impossible to handle the large amount of smoke generated by welding. For this reason, we propose a large robot welding workstation with smoke treatment. Utility Model Content

[0015] In summary, the present invention has the following beneficial effects:

[0016] 1. The utility model is provided with an exhaust fan, a fume hood and a telescopic exhaust pipe. First, the robot to be welded is placed on the workbench. Then, the height of the fume hood is reasonably adjusted according to the size of the robot. Specifically, the fume hood is pulled, and the telescopic exhaust pipe above the fume hood will assist the movement of the fume hood until the fume hood moves to a suitable position. Then, the exhaust fan is started to simultaneously carry out the welding operation on the robot. A large amount of smoke and dust generated during the welding process will be sucked into the fume hood under the action of the exhaust fan, and finally discharged through the telescopic exhaust pipe, which well protects the welding environment, avoids the situation where the operator is disturbed by the smoke and dust, and improves the welding effect of the robot.

[0017] 2. The utility model provides a purification box and a filter box. After the smoke is sucked into the smoke hood, the smoke will enter the first air cavity, and then the smoke will flow to both sides and then enter the filter box. At this time, the filter in the filter box will filter the smoke, thereby removing particulate matter in the smoke. At the same time, the air pressure generated by the smoke will push the cleaning plate to move inward and squeeze the return spring. When the cleaning plate moves, the smoke will flow into the purification box through the outlet valve and the connecting pipe. At this time, the activated carbon particles in the purification box can purify the smoke and remove harmful components in the smoke. Finally, the purified smoke will flow to the second air cavity and be discharged through the telescopic exhaust pipe. BRIEF DESCRIPTION OF THE DRAWINGS

The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0025] The following describes an embodiment of the present invention based on its overall structure.

[0026] A large-scale robot welding workstation with smoke and dust handling, such as Figure 1-5 As shown, it includes a workbench 1, the bottom end of the workbench 1 is fixedly connected to a base 2, and a fume hood 3 for inhaling welding fumes is provided above the workbench 1, a mounting plate 5 is provided inside the fume hood 3, and a plurality of exhaust fans 6 for providing suction are installed at the bottom end of the mounting plate 5, and a telescopic exhaust pipe 4 for discharging fumes is also installed at the top of the fume hood 3;

[0027] Furthermore, in this embodiment, a partition 7 is fixed to the inner wall of the smoke hood 3 above the mounting plate 5, and a first air cavity 8 is formed between the partition 7 and the mounting plate 5, and a second air cavity 9 is formed between the partition 7 and the top wall of the smoke hood 3, and the telescopic smoke exhaust pipe 4 is connected to the inside of the second air cavity 9, and both sides of the first air cavity 8 are connected to the filter box 10 installed on the outer wall of the smoke hood 3, and both sides of the second air cavity 9 are connected to the purification box 11 installed on the outer wall of the smoke hood 3.

[0028] See also Figure 3The top of the filter box 10 is provided with an air outlet valve 12 connected to its interior, and the bottom of the purification box 11 is provided with an air inlet valve 13 connected to its interior. A connecting pipe 14 is connected between the air outlet valve 12 and the air inlet valve 13 to realize the circulation of smoke and dust.

[0029] See also Figure 3 The interior of the purification box 11 is filled with activated carbon particles to purify the smoke.

[0030] See also Figure 3-5 A filter screen 15 is installed inside the filter box 10, and a cleaning plate 16 is provided on the inner side of the filter screen 15, which is slidably connected to the inner wall of the filter box 10. The inner end of the cleaning plate 16 is connected to a return spring 17 installed on the inner wall of the filter box 10, and the outer end of the cleaning plate 16 is provided with multiple groups of cleaning cones 18 distributed in an array, and the diameter of the cleaning cone 18 is smaller than the aperture of the filter screen 15, so as to realize automatic cleaning of the filter screen 15.

[0031] The working principle of the utility model is as follows: first, the robot to be welded is placed on the workbench 1, and then the height of the smoke hood 3 is reasonably adjusted according to the size of the robot. Specifically, the smoke hood 3 is pulled, and the telescopic smoke exhaust pipe 4 above the smoke hood 3 will assist the movement of the smoke hood 3 until the smoke hood 3 moves to a suitable position. Then, the exhaust fan 6 is started to simultaneously carry out the welding operation of the robot. A large amount of smoke and dust generated during the welding process will be sucked into the smoke hood 3 under the action of the exhaust fan 6, and finally discharged through the telescopic smoke exhaust pipe 4, which well protects the welding environment, avoids the situation where the operator is disturbed by the smoke and dust, and improves the welding effect of the robot.

[0032] In the above process, after the smoke is sucked into the smoke hood 3, the smoke will enter the first air cavity 8, and then the smoke will flow to both sides and then enter the filter box 10. At this time, the filter 15 in the filter box 10 will filter the smoke, thereby removing particulate matter in the smoke. At the same time, the air pressure generated by the smoke will push the cleaning plate 16 to move inward and squeeze the return spring 17. When the cleaning plate 16 moves, the smoke will flow into the purification box 11 through the outlet valve 12 and the connecting pipe 14. At this time, the activated carbon particles in the purification box 11 can purify the smoke and remove harmful components in the smoke. Finally, the purified smoke will flow into the second air cavity 9 and be discharged through the telescopic exhaust pipe 4.

[0033] In addition, after the welding operation is completed, the pressure of the smoke and dust pressure on the cleaning plate 16 will disappear. At this time, the cleaning plate 16 will move outward and reset under the action of the reset spring 17. Therefore, the cleaning plate 16 can use the cleaning cone 18 on its end face to clear the filter 15, that is, to achieve a cleaning effect on the filter 15.
