[0002] During the automobile production process, it is often necessary to process and weld the plates in automobile parts. During welding, people generally use a welding gun to weld two plates. After welding, people use a hammer to knock the weld. On the one hand, it ensures the stability of welding, and on the other hand, it is to prevent the paint from falling off after welding. The existing equipment needs to be manually knocked after welding, and cannot be automatically knocked during welding, which leads to increased labor costs. In addition, the secondary manual knocking affects the working efficiency of the equipment.

[0004] The above-mentioned device has the following problems during actual use: the device can collect waste slag, dust and other foreign matter after hammering and gas generated after welding with a welding torch through the mutual cooperation of the suction fan and the suction shell, but the gas contains a large amount of harmful gas during the period when the gas is stored in the collection box. Therefore, when the harmful gas is discharged, the harmful gas will cause harm to the life and health of the workers and pollute the environment, posing certain safety hazards; and, if the workers use the purification mechanism to deal with the harmful gas in time, on the one hand, it increases the work process and brings unnecessary trouble to the workers' work, and on the other hand, the workers may inhale harmful gases during operation, which poses a risk of dangerous operation.

[0016] The principles and advantages of this solution are: When welding the welding components through the suction fan, the harmful gases and foreign objects such as debris and dust generated are all sucked into the column box. When the harmful gases flow in the air duct, the purification liquid can be converted into atomized purification liquid through the atomizing nozzle. During the mixing of the atomized purification liquid and the harmful gases, the atomized purification liquid can process the harmful gases and reduce the amount of harmful gases, ensuring that after the gases are discharged from the column box, there is no pollution to the environment and no harm to the human body.

[0017] The purpose of setting up the atomizing nozzle is to expand the contact area between the purification liquid and the harmful gas, so that the purification liquid can contact with more harmful gases, further ensuring that the harmful gases can be treated more thoroughly.

[0018] During the period when the atomizing nozzle sprays the atomized purification liquid, the rubber tube can rotate, so the atomizing nozzle can rotate in a circumferential direction, thereby expanding the scope of action of the atomizing nozzle, enhancing the effect of the atomizing nozzle, and allowing the atomized purification liquid to diffuse over a large area, ensuring that the atomized purification liquid contacts more harmful gases, further improving the purification efficiency, and enhancing the purification effect.

[0019] When the extrusion block moves vertically upward, when the extrusion block contacts the rubber tube, the extrusion block continues to move, thereby causing the rubber tube to deform; during the deformation of the rubber tube, the diameter of the rubber tube will be squeezed and become smaller, thereby increasing the pressure in the rubber tube, that is, the atomized purification liquid sprayed from the atomizing nozzle can increase the effective distance of the atomized purification liquid after the rubber tube is deformed; when the extrusion block moves vertically downward, the diameter of the rubber tube gradually returns to its initial state, thereby causing the effective distance of the atomized purification liquid to gradually return to its initial state; therefore, through the deformation of the rubber tube, the effective distance of the atomized purification liquid can be continuously adjusted, so that the atomized purification liquid can contact more harmful gases during the period when the effective distance changes, further expanding the effective range of the atomized purification liquid, and ensuring that the harmful gases are purified more comprehensively and fully.

[0020] During the purification of harmful gases, foreign matter such as debris and dust in the harmful gases can be adsorbed by the dust collector under the action of the dust collector, that is, the debris and dust in the harmful gases will all adhere to the dust collector, thereby separating the debris, dust and other foreign matter in the harmful gases. On the one hand, it reduces the harm of debris, dust and other foreign matter to workers, and on the other hand, it improves the utilization rate of the atomized purification liquid, so that the atomized purification liquid can better purify the harmful gases, thereby enhancing the purification effect of the atomized purification liquid on the harmful gases.

[0021] While the harmful gas is flowing in the air duct, the intermittent reciprocating rotation of the two baffles can, on the one hand, extend the retention time of the harmful gas in the air duct, ensuring that the harmful gas can be treated more fully and foreign matter such as debris and dust can all adhere to the dust collection tube; on the other hand, there is no need to manually open and close the air duct, thereby achieving automatic intermittent discharge of the gas, simplifying the work process and improving the practicability of the device.

[0022] Through the rotation of the dust collection cylinder and the vertical reciprocating motion of the cleaning block, the inner wall of the dust collection cylinder can be acted on by the cleaning block in both the depth direction and the circumferential direction, ensuring that no debris, dust and other foreign matter are attached to any position on the inner wall of the dust collection cylinder, and eventually fall into the collection box, thereby making the dust collection cylinder always in an efficient working state, that is, debris, dust and other foreign matter in the harmful gas can all adhere to the dust collection cylinder, further enhancing the treatment effect on the harmful gas.

[0023] While the cleaning block is making vertical reciprocating motion with the guide block, the cleaning block itself can also make vertical reciprocating motion, so that the cleaning block has a certain force; therefore, the cleaning block can clean away foreign matter such as debris and dust with strong adhesion from the dust collection cylinder, further ensuring that foreign matter such as debris and dust adhering to the dust collection cylinder can be completely cleaned, that is, the dust collection cylinder can efficiently complete the adsorption of foreign matter such as debris and dust, further improving the working efficiency of the dust collection cylinder.

[0024] After being treated with atomized purification liquid, the harmful gas can be filtered again by the filter plate to complete secondary purification. On the one hand, it further ensures that when the gas is discharged out of the column box, it does not pollute the environment or harm the human body. On the other hand, it can perform secondary filtration on foreign matter such as debris and dust mixed in the gas, ensuring that foreign matter such as debris and dust will not be discharged with the gas, thereby enhancing the gas treatment effect and improving the treatment efficiency.

[0025] Through the rotation of the filter plate and the rotation of the elliptical disk, the elliptical disk can clean up the debris, dust and other foreign matter remaining on the filter plate, so that the debris, dust and other foreign matter on the filter plate can all fall into the collection box; that is, it is ensured that the filter plate will not be blocked by debris, dust and other foreign matter, and the filtering effect of the filter plate is enhanced, so that the filter plate can always be in an efficient working state, complete the purification of the gas, and the filtering of debris, dust and other foreign matter.

[0026] During the vertical downward movement of the bristle layer, when the bristle layer is against the filter plate, the bristle layer continues to move and the bristle layer is deformed; during the deformation of the bristle layer, on the one hand, the contact area between the bristle layer and the filter plate can be enlarged, thereby enhancing the effect of the bristle layer, so that the bristle layer can more fully clean the filter plate, and on the other hand, the bristle layer can extend into the filter holes of the filter plate, and the bristle layer can clean up foreign matter such as debris and dust that is blocked in the filter holes, so that foreign matter such as debris and dust no longer blocks the filter holes, further improving the gas purification quality of the filter plate.

[0027] During the rotation of the filter plate, the cleaning range of the brush layer on the filter plate is expanded, so that any position on the filter plate can be cleaned under the action of the brush layer, ensuring that debris, dust and other foreign matter can be cleaned more comprehensively and thoroughly, enhancing the filtering effect of the filter plate, and improving the filtering efficiency of the filter plate; that is, through the combined action of the vertical reciprocating motion of the brush layer and the rotation of the filter plate, on the one hand, the action range of the brush layer can be expanded and the cleaning effect of the brush layer can be enhanced, and on the other hand, it can ensure that the filter plate is always in an efficient filtering state, thereby improving the working efficiency of the filter plate and thereby ensuring the quality of gas purification.

[0028] During the movement of the bristle layer, the auxiliary block acts on the bristle layer, causing the bristle layer to swing laterally. On the one hand, this enhances the force of the bristle layer and improves the efficiency of the bristle layer. On the other hand, it causes the bristle layer to deform, expanding the range of action of the bristle layer and enhancing the effect of the bristle layer, thereby ensuring that the filter plate can better purify the gas and filter foreign matter such as dust and debris.

[0053] The linkage unit includes a second annular rack 62 and a fifth gear 63 ; the second annular rack 62 is fixedly connected to the filter plate 35 ; the fifth gear 63 is fixedly connected to the linkage shaft 38 , and the fifth gear 63 is meshed with the second annular rack 62 .

[0054] The linkage shaft 38 and the rotating shaft 36 are both rotationally connected to the gear box 64; the motion unit includes the gear box 64, a first bevel gear, and a second bevel gear; the gear box 64 is fixedly connected to the inner wall of the cylindrical box 3; the first bevel gear and the second bevel gear are both located in the gear box 64; the first bevel gear is fixedly connected to the linkage shaft 38, the second bevel gear is fixedly connected to the rotating shaft 36, and the first bevel gear is meshed with the second bevel gear.

[0055] Specific implementation process: The automobile parts to be welded are placed on the welding table 1, and the welding head 16 is driven to weld the automobile parts by the interaction of the first cylinder 12 and the second cylinder 14; while the welding head 16 is welding the automobile parts, the suction fan 4 is started, so that the harmful gas and foreign matter such as debris and dust generated by welding can be sucked into the cylindrical box 3 along the suction cover 17 and then through the hose 18. When the harmful gas flows in the wind tube 5, the servo motor 27 is started, and the output shaft of the servo motor 27 drives the first screw 19 to rotate; during the rotation of the first screw 19, the collection box 34 rotates synchronously; during the rotation of the collection box 34, the second annular rack 62 rotates synchronously; during the rotation of the second annular rack 62, the fifth gear 63 is rotated because the second annular rack 62 is meshed with the fifth gear 63; during the rotation of the fifth gear 63, the linkage shaft 38 rotates synchronously; during the rotation of the linkage shaft 38, the second cam 39 rotates synchronously.

[0056] During the rotation of the second cam 39, when the raised portion of the second cam 39 abuts against the piston block 9, the piston block 9 moves vertically upward and the fifth spring 61 is compressed. When the raised portion of the second cam 39 no longer abuts against the piston block 9, the piston block 9 is reset under the action of the fifth spring 61 and moves vertically downward; therefore, the piston block 9 can perform vertical reciprocating motion.

[0057] When the piston block 9 moves vertically downward, the piston block 9 extracts liquid, and the purified liquid flows into the piston cylinder 7 along the liquid inlet pipe and is temporarily stored; when the piston block 9 moves vertically upward, the purified liquid stored in the piston cylinder 7 is discharged through the liquid discharge pipe. After the purified liquid is discharged, it can be converted into atomized purified liquid through the atomizing nozzle 10. During the period when the atomized purified liquid is mixed with the harmful gas, the atomized purified liquid can process the harmful gas, reduce the amount of the harmful gas, and thus reduce the harm of the harmful gas.

[0058] The atomizing nozzle 10 is provided to expand the contact area between the purified liquid and the harmful gas, so that the purified liquid can contact with more harmful gases, further ensuring that the harmful gases can be treated more thoroughly.

[0059] During the period when the atomizing nozzle 10 sprays the atomized purification liquid, the linkage shaft 38 drives the short tube 54 to rotate through the belt 60; during the rotation of the short tube 54, the rubber tube 55 rotates synchronously. Since the rubber tube 55 can rotate, the atomizing nozzle 10 can rotate in a circumferential direction, thereby expanding the action range of the atomizing nozzle 10, enhancing the action effect of the atomizing nozzle 10, allowing the atomized purification liquid to diffuse out over a large area, ensuring that the atomized purification liquid contacts more harmful gases, further improving the purification efficiency, and enhancing the purification effect.

[0060] During the rotation of the first screw 19, the first gear 23 rotates synchronously; during the rotation of the first gear 23, the second gear 25 rotates due to the meshing of the first gear 23 and the second gear 25; during the rotation of the second gear 25, the first annular rack 26 rotates synchronously driven by the second gear 25; during the rotation of the first annular rack 26, the annular hollow block 56 rotates synchronously; during the rotation of the annular hollow block 56, the annular hollow block 56 can drive the wedge block 58 to perform vertical reciprocating motion through the combined action of the wedge surface groove and the fourth spring 59; during the vertical reciprocating motion of the wedge block 58, the extrusion block 57 moves synchronously.

[0061] When the extrusion block 57 moves vertically upward, when the extrusion block 57 contacts the rubber tube 55, the extrusion block 57 continues to move, thereby causing the rubber tube 55 to deform; during the deformation of the rubber tube 55, the diameter of the rubber tube 55 will be squeezed to become smaller, thereby increasing the pressure in the rubber tube 55, that is, the atomized purification liquid sprayed by the atomizing nozzle 10 can increase the effective distance of the atomized purification liquid after the rubber tube 55 is deformed; when the extrusion block 57 moves vertically downward, the diameter of the rubber tube 55 gradually returns to the initial state, thereby causing the effective distance of the atomized purification liquid to gradually return to the initial state; therefore, through the deformation of the rubber tube 55, the effective distance of the atomized purification liquid can be continuously adjusted, so that the atomized purification liquid can contact more harmful gases during the period when the effective distance changes, further expanding the effective range of the atomized purification liquid, and ensuring that the harmful gases are purified more comprehensively and fully.

[0062] To sum up, by rotating the rubber tube 55 and changing the diameter of the rubber tube 55, the scope of action of the atomized purification liquid can be expanded and the effect of the atomized purification liquid can be enhanced, so that the harmful gas can be treated more comprehensively and fully during the flow in the wind tube 5, ensuring that the gas is discharged without pollution to the environment and harm to the human body.

[0063] During the purification of harmful gases, foreign matter such as debris and dust in the harmful gases can be adsorbed by the dust collection tube 6 under the action of the dust collection tube 6, that is, the debris and dust in the harmful gases will all adhere to the dust collection tube 6, thereby separating the debris, dust and other foreign matter in the harmful gases. On the one hand, it reduces the harm of foreign matter such as debris and dust to workers, and on the other hand, it improves the utilization rate of the atomized purification liquid, so that the atomized purification liquid can better purify the harmful gases, thereby enhancing the purification effect of the atomized purification liquid on the harmful gases.

[0064] When harmful gases flow in the air duct 5, when the raised portion of the second cam 39 abuts against the transverse block 44, the transverse block 44 moves vertically downward, and the second spring 42 is stretched. When the raised portion of the second cam 39 no longer abuts against the transverse block 44, the transverse block 44 is reset under the action of the second spring 42, and the transverse block 44 moves vertically upward; therefore, the transverse block 44 can perform vertical reciprocating motion.

[0065] During the movement of the transverse block 44, the second rack 48 moves synchronously; during the movement of the second rack 48, the fourth gear 47 can rotate back and forth half a circle driven by the second rack 48; during the rotation of the fourth gear 47, the power shaft 46 rotates synchronously; during the rotation of the power shaft 46, the baffle 11 rotates synchronously; that is, through the intermittent reciprocating rotation of the two baffles 11, on the one hand, the retention time of harmful gases in the air cylinder 5 can be extended, ensuring that the harmful gases can be treated more fully, and foreign matter such as debris and dust can be fully adhered to the dust collection cylinder 6. On the other hand, there is no need to manually open and close the air cylinder 5, thereby realizing automatic intermittent discharge of gas, simplifying the work process, and improving the practicability of the device.

[0066] During the forward and reverse rotation of the first screw 19, the first nut seat 21 can make vertical reciprocating motion along the length direction of the first guide rod 20; during the movement of the first nut seat 21, the cleaning block 22 moves synchronously; during the movement of the cleaning block 22, the dust collection cylinder 6 rotates synchronously driven by the first annular rack 26; that is, through the rotation of the dust collection cylinder 6 and the vertical reciprocating motion of the cleaning block 22, the depth direction and circumferential direction of the inner wall of the dust collection cylinder 6 can be acted on by the cleaning block 22, ensuring that no debris, dust and other foreign matter are attached to any position on the inner wall of the dust collection cylinder 6, and finally fall into the collection box 34, so that the dust collection cylinder 6 is always in an efficient working state, further enhancing the treatment effect of harmful gases.

[0067] During the vertical reciprocating motion of the first nut seat 21, the short shaft 24 moves synchronously; during the movement of the short shaft 24, the third gear 31 moves synchronously; during the movement of the third gear 31, the third gear 31 is engaged with the first rack 33, so that the third gear 31 rotates; during the rotation of the third gear 31, the short shaft 24 rotates synchronously; therefore, while the short shaft 24 reciprocates vertically, the short shaft 24 can also rotate; during the rotation of the short shaft 24, the first cam 30 rotates synchronously.

[0068] During the rotation of the first cam 30, when the raised portion of the first cam 30 abuts against the cleaning block 22, the cleaning block 22 moves vertically downward, and the first spring 32 is compressed. When the raised portion of the first cam 30 no longer abuts against the cleaning block 22, the cleaning block 22 is reset under the action of the first spring 32, and the cleaning block 22 moves vertically upward; therefore, the cleaning block 22 can make vertical reciprocating motion, that is, while the cleaning block 22 makes vertical reciprocating motion with the guide block 29, the cleaning block 22 itself can also make vertical reciprocating motion.

[0069] During the vertical reciprocating motion of the cleaning block 22 itself, the cleaning block 22 has a certain force; therefore, the cleaning block 22 can clean out foreign matter such as debris and dust with strong adhesion from the dust collection tube 6, further ensuring that foreign matter such as debris and dust adhering to the dust collection tube 6 can be completely cleaned, that is, the dust collection tube 6 can efficiently complete the adsorption of foreign matter such as debris and dust, further improving the working efficiency of the dust collection tube 6.

[0070] After being treated with the atomized purification liquid, the harmful gas can be filtered again by the filter plate 35 to complete the secondary purification. On the one hand, it further ensures that when the gas is discharged from the cylindrical box 3, it does not pollute the environment and harm the human body. On the other hand, it can perform secondary filtration on foreign matter such as debris and dust mixed in the gas, ensuring that foreign matter such as debris and dust will not be discharged with the gas, thereby enhancing the treatment effect on the gas and improving the treatment efficiency.

[0071] During the secondary filtration of harmful gases by the filter plate 35, the rotating shaft 36 can rotate under the joint action of the first bevel gear and the second bevel gear; during the rotation of the rotating shaft 36, the elliptical disk 37 rotates synchronously; that is, through the rotation of the filter plate 35 and the rotation of the elliptical disk 37, the elliptical disk 37 can clean up the debris, dust and other foreign matter remaining on the filter plate 35, so that the debris, dust and other foreign matter on the filter plate 35 can all fall into the collection box 34; that is, it is ensured that the filter plate 35 will not be blocked by debris, dust and other foreign matter, and the filtering effect of the filter plate 35 is enhanced, so that the filter plate 35 can always be in an efficient working state to complete the purification of the gas and the filtering of debris, dust and other foreign matter.

[0072] During the vertical reciprocating motion of the transverse block 44, the vertical block 45 moves synchronously; during the vertical downward motion of the vertical block 45, the disc 40 moves vertically downward under the action of the vertical block 45, and the second spring 42 is stretched; during the vertical upward motion of the vertical block 45, the disc 40 is reset under the action of the second spring 42, and the disc 40 makes vertical reciprocating motion; during the movement of the disc 40, the bristle layer 41 moves synchronously.

[0073] During the vertical downward movement of the bristle layer 41, when the bristle layer 41 is against the filter plate 35, the bristle layer 41 continues to move and the bristle layer 41 is deformed; during the deformation of the bristle layer 41, on the one hand, the contact area between the bristle layer 41 and the filter plate 35 can be enlarged, thereby enhancing the effect of the bristle layer 41, so that the bristle layer 41 can more fully clean the filter plate 35; on the other hand, the bristle layer 41 can extend into the filter holes of the filter plate 35, and the bristle layer 41 can clean up foreign matter such as debris and dust that is clogged in the filter holes, so that foreign matter such as debris and dust no longer clogs the filter holes, thereby further improving the gas purification quality of the filter plate 35.

[0074] During the rotation of the filter plate 35, the cleaning range of the bristle layer 41 on the filter plate 35 is expanded, so that any position on the filter plate 35 can be cleaned under the action of the bristle layer 41, ensuring that foreign matter such as debris and dust can be cleaned more comprehensively and thoroughly, thereby enhancing the filtering effect of the filter plate 35 and improving the filtering efficiency of the filter plate 35; that is, through the combined action of the vertical reciprocating motion of the bristle layer 41 and the rotation of the filter plate 35, on the one hand, the action range of the bristle layer 41 can be expanded and the cleaning effect of the bristle layer 41 can be enhanced, and on the other hand, it can ensure that the filter plate 35 is always in an efficient filtering state, thereby improving the working efficiency of the filter plate 35 and further ensuring the quality of gas purification.

[0075] During the movement of the bristle layer 41, the second screw 49 rotates synchronously under the drive of the power shaft 46; during the rotation of the second screw 49, the second nut seat 51 can reciprocate along the length direction of the second guide rod 50; during the movement of the second nut seat 51, the auxiliary block 53 moves synchronously. Through the action of the auxiliary block 53 on the bristle layer 41, the bristle layer 41 can swing horizontally, which on the one hand enhances the action force of the bristle layer 41 and improves the action efficiency of the bristle layer 41; on the other hand, the bristle layer 41 is deformed, the action range of the bristle layer 41 is expanded, and the action effect of the bristle layer 41 is enhanced, that is, it ensures that the filter plate 35 can better purify the gas and filter foreign matter such as dust and debris.
