Therefore, advanced equipment must be used to produce automated machinery to replace human labor and meet the needs of industrial automation. Among them, industrial robots are one of the important products in its development process. It not only improves the efficiency of labor production, but also can replace humans to complete high-intensity, dangerous, repetitive and boring work, reducing the intensity of human labor, which can be said to kill two birds with one stone.

[0033] The smoke protection component 7 is used to protect and absorb impurities and gases generated by welding of the welding head 6;

[0034] Furthermore, the smoke protection component 7 is composed of a protective cover 10, a connecting ring 11, a connecting head 12, a connecting pipe 13, a conveying pipe 14, a processing box 15, a filter plate 16 and an activated carbon filter 17. The protective cover 10 is located on the outside of the welding head 6, the connecting ring 11 is located at the bottom of the protective cover 10, multiple groups of connecting heads 12 are located at the end of the connecting ring 11 away from the protective cover 10, two groups of connecting pipes 13 are located at the top of the connecting ring 11 and located inside the protective cover 10, the conveying pipe 14 is located on the outside of the protective cover 10, the processing box 15 is located inside the third mobile frame 5, the filter plate 16 is located inside the processing box 15, and the activated carbon filter 17 is located above the filter plate 16 and located inside the processing box 15. When the welding head 6 is in operation, the smoke protection component 7 can protect and absorb impurities and smoke generated by the operation of the welding head 6, prevent welding sparks from splashing and damaging the main body, absorb and filter the generated smoke, and then discharge it to prevent the generation of harmful gases, which may affect the health of the staff.

[0035] Among them, a cavity is opened inside the connecting ring 11, and the interior of the cavity and the interior of the connecting head 12 are designed to be interconnected. The connecting pipe 13 extends to the interior of the connecting ring 11 and connects with the cavity. The connecting pipe 13 is connected to the cavity so that the connecting pipe 13 can be connected to the connecting head 12.

[0036] Secondly, two sets of connecting sleeves 18 are provided on the outside of the protective cover 10. The internal structure size of the connecting sleeve 18 is designed to correspond to the external structure size of the connecting pipe 13. The connecting pipe 13 is connected to the conveying pipe 14 through the connecting sleeve 18. The connecting pipe 13 is connected to the connecting sleeve 18 so that the connecting pipe 13 can extend to the outside of the protective cover 10 and connect to the conveying pipe 14.

[0037] Furthermore, an air pump 19 is provided on the top of the processing box 15, and the input end of the air pump 19 is connected to the delivery pipe 14, and the output end of the air pump 19 is provided with a guide pipe 20. The end of the guide pipe 20 away from the air pump 19 extends to the interior of the processing box 15, and the delivery pipe 14 is connected to the input end of the air pump 19, and then the guide pipe 20 is extended to the interior of the processing box 15. When the welding head 6 is in operation, the air pump 19 is started, so that the connecting head 12 can guide the smoke generated by the welding head 6 into the interior of the cavity, so that the smoke can be introduced into the interior of the connecting pipe 13, and is introduced into the interior of the guide pipe 20 through the delivery pipe 14 and the air pump 19, so that it can be introduced into the interior of the processing box 15.

[0038] Furthermore, a partition 21 is provided inside the treatment box 15 and on the outside of the filter plate 16 and the activated carbon filter 17, and the interior of the treatment box 15 is filled with filtered liquid. The partition 21 divides the interior of the treatment box 15 into two groups of spaces. When the flue gas is introduced into the interior of the treatment box 15, it comes into contact with the filtered liquid, and the flue gas can be cooled and filtered by the filtered liquid. The initially filtered flue gas comes into contact with the filter plate 16, and can be further filtered by the filter plate 16. The filtered harmful gas then reaches the activated carbon filter 17, and the activated carbon filter 17 effectively adsorbs the odor in the harmful gas and purifies the harmful substances in the harmful gas, thereby improving the quality of the exhaust gas and reducing health and safety hazards.

[0039] The clamping unit is used to clamp and limit the weldment, and the clamping unit is composed of a clamping assembly 8 and a synchronization assembly 9. The clamping assembly 8 is located at both ends of the top of the welding table body 1, and the synchronization assembly 9 is located on the outside of the clamping assembly 8;

[0040] Furthermore, the clamping assembly 8 is composed of a clamping block 22, a rotating rod 23, a moving block 24, a forward and reverse screw rod 25, a guide rod 26, a guide block 27, a connecting plate 28 and a suction cup 29. The two groups of clamping blocks 22 are respectively slidably connected to the two ends of the top of the welding table main body 1, the two groups of rotating rods 23 are both rotatably connected to the outside of the clamping block 22, the moving block 24 is rotatably connected to the end of the rotating rod 23 away from the clamping block 22, the forward and reverse screw rod 25 is located inside the two groups of moving blocks 24, the guide rod 26 is rotatably connected to the bottom of the clamping block 22, the guide block 27 is located between the two groups of guide rods 26, the connecting plate 28 and the top of the guide block 27, and multiple groups of suction cups 29 are all located on the top of the connecting plate 28. When welding the weldment, the clamping assembly 8 can be used to clamp and limit it, so that the weldment can be welded conveniently to prevent offset and affect the welding effect.

[0041] Furthermore, the moving block 24 is threadedly connected to the forward and reverse screw rods 25, and guide grooves 30 are provided at both ends of the guide block 27 near the two groups of guide rods 26. The internal structure size of the guide groove 30 is designed to correspond to the external structure size of the guide rod 26. The guide rod 26 extends to the inside of the guide groove 30 and is rotatably connected to a guide wheel. When the forward and reverse screw rods 25 rotate, the moving block 24 can be driven to displace, so that the rotating rod 23 can be displaced, and the clamping block 22 can be driven to displace, contact the welded part, and clamp it to limit the position. By displacing the clamping block 22, the guide rod 26 can be driven to displace, and the guide groove 30 cooperates with the guide wheel to drive the guide block 27 to displace, so that the connecting plate 28 can be displaced, and the suction cup 29 can be displaced to contact the bottom of the welded part.

[0042] Furthermore, multiple groups of suction cups 29 are interconnected by an air pipe 31. One end of the air pipe 31 away from the suction cup 29 is fixedly connected to the input end of the air pump. When the suction cup 29 contacts the bottom of the weldment, the air pump is started to generate negative pressure inside the suction cup 29 through the air pipe 31, so that the bottom of the weldment is adsorbed, thereby increasing the effect of limiting the weldment.

[0043] Furthermore, the synchronization assembly 9 is composed of a first synchronization wheel 32, a drive belt 33, a second synchronization wheel 34, a drive rod 35, a first bevel gear 36, a second bevel gear 37 and a transmission rod 38. The first synchronization wheel 32 is fixedly connected to the outer side of the forward and reverse screw rods 25, the drive belt 33 is meshedly connected to the outer side of the first synchronization wheel 32, the second synchronization wheel 34 is meshedly connected to the inside of the drive belt 33 and away from one end of the first synchronization wheel 32, the drive rod 35 is fixedly connected to the inside of the second synchronization wheel 34, the first bevel gear 36 is fixedly connected to the outer side of the drive rod 35, the second bevel gear 37 is meshedly connected to the outer side of the first bevel gear 36, and the transmission rod 38 is located at Between the two groups of second bevel gears 37, one end of the driving rod 35 away from the second synchronous wheel 34 is fixedly connected to the driving end of the driving motor. When the driving motor is started, the driving rod 35 is driven to rotate, so that the first bevel gear 36 can rotate, and the second bevel gear 37 is driven to rotate, so that the transmission rod 38 can rotate, and the other group of second bevel gears 37 is driven to rotate, so that the other group of first bevel gears 36 can rotate. Therefore, the two groups of driving rods 35 can rotate, driving the second synchronous wheel 34 to rotate, and the first synchronous wheel 32 is driven to rotate through the driving belt 33, so that the two groups of forward and reverse screw rods 25 can rotate.

[0044] In this embodiment, the implementation scenario is specifically as follows: in actual use, the welding piece is prevented from being placed on the top of the welding table body 1, and the driving motor is started to drive the driving rod 35 to rotate, so that the first bevel gear 36 can be rotated, and the second bevel gear 37 can be rotated, so that the transmission rod 38 can be rotated, and the other set of second bevel gears 37 can be rotated, so that the other set of first bevel gears 36 can be rotated, so that the two sets of driving rods 35 can be rotated, and the second synchronous wheel 34 can be rotated, and the first synchronous wheel 32 can be rotated by the driving belt 33, so that the two sets of positive and negative screw rods 25 can be rotated. When the forward and reverse screw rods 25 rotate, the moving block 24 can be driven to move, so that the rotating rod 23 can be moved, and the clamping block 22 can be driven to move, contact the welded part, and clamp it to limit the position. By moving the clamping block 22, the guide rod 26 can be driven to move, and the guide block 27 can be driven to move through the guide groove 30 and the guide wheel, so that the connecting plate 28 can be moved, and the suction cup 29 can be driven to move, contact the bottom of the welded part, and the air pump is started. Through the air pipe 31, negative pressure is generated inside the suction cup 29, and the bottom of the welded part is adsorbed, thereby increasing the effect of limiting the welded part. The clamping assembly 8 can be used to clamp and limit the welding result, so that the welding of the welding piece can be facilitated to prevent deviation, which will affect the welding effect. The first mobile frame 3, the second mobile frame 4 and the third mobile frame 5 enable the welding head 6 to move in all directions, which is convenient for welding the welding piece. When the welding head 6 is in operation, the protective cover 10 is used to prevent welding sparks from splashing and damaging the main body. The air pump 19 is started, so that the connecting head 12 can guide the smoke generated by the welding head 6 into the interior of the cavity, so that the smoke can be introduced into the interior of the connecting pipe 13, and it is introduced into the guide pipe 20 through the delivery pipe 14 and the air pump 19. The smoke is then introduced into the treatment box 15, and contacts with the filtrate, through which the smoke is cooled and filtered. The initially filtered smoke contacts with the filter plate 16, through which it is further filtered. The filtered harmful gas then reaches the activated carbon filter 17, and the activated carbon filter 17 effectively adsorbs the odor in the harmful gas and purifies the harmful substances in the harmful gas, thereby improving the quality of the exhaust gas and reducing health and safety hazards. Compared with the existing micro-welding robot, the present invention can improve the overall practicality of the micro-welding robot through design.
