Description

Technical Field

[0001] This invention relates to the field of automotive wiring harness welding technology, specifically to an integrated device for electrostatic dust removal and tin dust melting and recovery of welding fumes from automotive wiring harnesses. Background Technology

[0002] In the production and processing of automotive wiring harnesses, welding is one of the core processes. Welding operations mostly use tin soldering technology, which generates a large amount of welding fumes containing tin dust. If these fumes are directly diffused into the production environment, they will not only cause a decline in the air quality of the workshop, but the unorganized emission of tin dust will also lead to a waste of tin resources. Therefore, it is necessary to use dust collection equipment to collect and remove the dust.

[0003] Existing dust collection equipment only has a simple fume collection function, with low dust removal efficiency, and cannot effectively recover tin dust. Furthermore, the welding and dust removal actions cannot be linked, which easily leads to problems such as delayed or missed fume collection. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an integrated electrostatic dust removal and tin dust melting and recovery device for automotive wiring harness welding fumes. This solves the problems of existing dust collection devices, which only have simple fume collection functions, low dust removal efficiency, and cannot effectively recover tin dust. Furthermore, the welding and dust removal actions cannot be linked, which can easily lead to problems such as delayed or missed fume collection.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an integrated equipment for electrostatic dust removal and tin dust melting and recovery of welding fumes from automotive wiring harnesses, comprising a frame, a dust collection component at the bottom of the frame, the dust collection component including a movable rod, a rod hole at the bottom of the frame, a movable rod slidably connected within the rod hole, a sealing plate fixedly connected to the top of the movable rod, a spring fixedly connected to the sealing plate on the opposite side of the frame, symmetrical circular holes at the bottom of the frame, a limiting rod slidably connected within the circular holes, the top of the limiting rod fixedly connected to the bottom of the sealing plate, a mounting plate fixedly connected to the top of the sealing plate, a ring at the center of the mounting plate, a fan installed inside the ring, a dust collection hole at one side of the frame, a dust collection bag inside the dust collection hole, a fixing component at the top of the mounting plate, and an auxiliary welding component at the bottom of the frame.

[0006] By adopting the above technical solution, the welding machine is powered on and welding is completed simultaneously with the fan and dust collection bag. The moment the welding machine starts welding, the fan is already in the best dust collection state. It can immediately collect the tin-containing dust fumes generated by welding under negative pressure. It can achieve rapid and precise capture from the source of the fumes, which not only ensures the effective recovery of tin dust, but also avoids the unorganized diffusion of welding fumes from the root, greatly reducing dust pollution in the workshop. At the same time, it avoids the problems of delayed fume collection, insufficient capture or leakage that are easy to occur in traditional equipment, making the collection and treatment of welding fumes more timely and efficient.

[0007] Through the mechanical force of the equipment linkage, the moment the pressing head presses the pressing switch, the fan and dust collection bag are fully connected, the movable plate and the support base are in contact, and the wire harness is precisely positioned at the welding station. At the same time, the welding machine is energized and welding begins. This achieves seamless connection between welding start-up, dust removal readiness, and wire harness positioning from the source, completely eliminating problems such as delayed welding fume collection and wire harness misalignment, and ensuring optimal coordination between welding and dust removal operations.

[0008] Preferably, the auxiliary welding assembly includes a sleeve, the bottom end of which is fixedly connected to the bottom of the frame, a lifting rod is slidably connected inside the sleeve, a support base is fixedly connected to the top end of the lifting rod, and a second spring is fixedly connected to the bottom end of the lifting rod, with the bottom end of the second spring fixedly connected to the bottom inner wall of the sleeve.

[0009] Preferably, guide rods are symmetrically fixedly connected to one side of the support base, and movable plates are slidably connected to the outer walls of the two guide rods. Springs are symmetrically fixedly connected to the side of the movable plates opposite to the support base, and springs are sleeved on the outer walls of the guide rods.

[0010] Preferably, a wire hole is provided on one side of the support base, and a rope is provided in the wire hole of the support base. One end of the rope is fixedly connected to the outer wall of the sealing plate, and the other end of the rope is fixedly connected to the outer wall of the movable plate.

[0011] Preferably, the movable plate has an internal mounting groove, a damping shaft is rotatably connected in the mounting groove, a placement plate is fixedly connected to the outer wall of the damping shaft, and a handle is fixedly connected to the bottom of the placement plate.

[0012] Preferably, a pressing head is fixedly connected to the bottom of the movable plate, a vertical pole is fixedly connected to the bottom of the frame, a pressing switch is installed at the top of the vertical pole, and the pressing switch is electrically connected to the welding machine.

[0013] Preferably, the bottom of the frame has a through hole, and a second limiting rod is slidably connected in the through hole of the frame. The top end of the second limiting rod is fixedly connected to the bottom of the support base.

[0014] Preferably, the fixing component includes a connecting frame, the bottom of which is fixedly connected to the top of the mounting plate, a fixing ring is fixedly connected to one end of the connecting frame, a welding machine is disposed inside the fixing ring, a screw hole is opened on the outer wall of the fixing ring, a locking bolt is threaded into the screw hole of the fixing ring, one end of the locking bolt abuts against the outer wall of the welding machine, and an atomizing component is disposed on one side of the fixing ring.

[0015] Preferably, a cylinder is installed on the top of the frame, and a push rod is fixedly connected to the output end of the cylinder, with the bottom end of the push rod contacting the top of the welding machine.

[0016] Preferably, the atomizing component includes a fixing rod, one end of which is fixedly connected to one side of a fixing ring, and the other end of which is equipped with an atomizing nozzle, and the top of the atomizing nozzle is fixedly connected to a connecting pipe.

[0017] Working principle: Place the wire harness to be welded on the placement plate, start the cylinder, drive the push rod to move down, the push rod presses down on the welding machine, the welding machine moves down and drives the mounting plate to move down through the connecting frame, the mounting plate drives the sealing plate to move down, the spring is compressed, the movable rod slides down along the rod hole of the frame, under the limiting cooperation of the limiting rod, the sealing plate moves down stably until the fan moves down to connect with the dust collection bag in the dust suction hole of the frame;

[0018] During the downward movement of the sealing plate, the rope fixed to it is pulled to move. The rope pulls the movable plate to move along the guide rod towards the support seat. The spring is compressed, and the movable plate drives the placement plate and the wire harness to be welded to move closer to the welding station at the same time, so as to realize the automatic alignment of the wire harness.

[0019] As the fan gradually moves down to connect with the dust collection bag, the welding machine descends synchronously with the mounting plate. When the welding machine descends to contact the top of the movable plate, its downward pressure pushes the support seat down as the welding machine continues to descend. The support seat drives the lifting rod to move down inside the sleeve, and the second spring is compressed. Under the limiting cooperation of the second limiting rod, the support seat moves down stably. When the support seat drives the bottom pressing head down to contact the pressing switch and squeeze the pressing switch, at this time the fan has just moved down to be fully connected with the dust collection bag, and one side of the movable plate has just moved to contact the side wall of the support seat. The wire harness is precisely positioned at the welding station. After the pressing switch is triggered, the welding machine is powered on and started. The welding machine is used to weld the wire harness.

[0020] During the welding process, the welding machine generates welding fumes containing tin dust. At the same time, the fan is working. Under the negative pressure suction of the fan, the welding fumes are drawn into the dust collection bag for collection after being guided by the fan.

[0021] During the welding process, the atomizing nozzle is connected to an external liquid source through a connecting pipe. The atomizing nozzle sprays atomized liquid droplets into the welding fume area. The atomized liquid droplets combine with the fine tin dust particles in the fume, making the dust particles heavier. This not only prevents the fine dust from spreading, but also improves the efficiency of subsequent electrostatic dust removal.

[0022] After the welding operation is completed, the cylinder is turned off, and the cylinder output end drives the push rod to reset upward. The downward pressure of the welding machine disappears, and the elastic restoring force of spring one pushes the sealing plate to move upward, driving the mounting plate and welding machine to reset to their initial positions simultaneously. After the sealing plate resets, the tension of the rope disappears, and the elastic restoring force of spring three pushes the movable plate to slide back along the guide rod to reset. At the same time as the movable plate resets, the elastic restoring force of spring two pushes the lifting rod and support seat to reset upward. The pressing head separates from the pressing switch, the welding machine is powered off and stops working, the fan also stops as the welding operation stops, and the atomizing component also stops atomizing and spraying. The entire set of equipment completes one welding and fume treatment operation and returns to the initial standby state, ready for the next round of wire harness welding operations.

[0023] This invention provides an integrated device for electrostatic dust removal and tin dust melting and recovery of welding fumes from automotive wiring harnesses. It has the following beneficial effects:

[0024] 1. This invention achieves simultaneous operation of the welding machine's power-on welding and the complete connection between the fan and dust collection bag. The moment the welding machine begins welding, the fan is already in optimal dust collection mode, which can immediately collect the tin-containing dust fumes generated during welding under negative pressure. This achieves rapid and precise capture from the source of the fumes, ensuring effective recovery of tin dust and preventing the unorganized diffusion of welding fumes at the source, greatly reducing dust pollution in the workshop. At the same time, it avoids problems such as delayed fume collection, insufficient capture, or leakage that are common in traditional equipment, making the collection and treatment of welding fumes more timely and efficient.

[0025] 2. This invention, through the mechanical force of equipment linkage, ensures that the moment the pressing head presses the pressing switch, the fan and dust collection bag are fully connected, the movable plate and support base are in contact, and the wire harness is precisely positioned at the welding station. Simultaneously, the welding machine is energized to begin welding. This achieves seamless connection between welding start-up, dust removal readiness, and wire harness positioning from the source, completely eliminating problems such as delayed welding fume collection and wire harness alignment deviation, and optimizing the coordination between welding and dust removal operations.

[0026] 3. This invention sprays atomized droplets into the welding fume area through an atomizing nozzle. The atomized droplets combine with fine tin dust particles in the fume, increasing the weight of the dust particles and causing them to agglomerate into larger particles. These larger particles can then be quickly drawn into the dust collection bag by the negative pressure of the fan for collection. This overcomes the limitations of a single dust collection bag in capturing micro-particle dust, achieving comprehensive recovery of tin dust of different particle sizes and greatly improving the overall dust collection rate. At the same time, the atomized droplets form an atomized barrier in the welding fume area, effectively inhibiting the unorganized diffusion of tin dust during welding and reducing the possibility of dust escaping into the workshop environment. This, combined with the negative pressure collection of the fan, creates a dual dust control effect, further reducing dust pollution in the workshop from the source and improving the on-site environment for welding operations.

[0027] 4. The present invention can effectively eliminate static electricity generated by dryness in the welding environment by spraying atomized droplets through the atomizing nozzle, neutralize the static charge on the surface of tin dust particles and equipment and workshop components, avoid dust adhering to the inner wall of equipment or workshop components due to static electricity and making it difficult to clean, further improve the thoroughness of dust collection, and reduce the safety hazards caused by static electricity.

[0037] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Please see the appendix Figure 1 - Appendix Figure 8 This invention provides an integrated device for electrostatic dust removal and tin dust melting and recovery of welding fumes from automotive wiring harnesses. The device includes a frame 1, a dust collection assembly 4 at the bottom of the frame 1, and a movable rod 401. A rod hole is provided at the bottom of the frame 1, and the movable rod 401 is slidably connected within the rod hole. A sealing plate 403 is fixedly connected to the top of the movable rod 401. A spring 402 is fixedly connected to the sealing plate 403 on the opposite side of the frame 1. Symmetrical circular holes are provided at the bottom of the frame 1. A limiting rod 404 is slidably connected inside the circular hole of frame 1. The top end of the limiting rod 404 is fixedly connected to the bottom of the sealing plate 403. A mounting plate 405 is fixedly connected to the top of the sealing plate 403. A ring 406 is provided in the middle of the mounting plate 405. A fan 407 is installed inside the ring 406. A dust suction hole is provided on one side of the frame 1. A dust collection bag 408 is provided in the dust suction hole of the frame 1. A fixing component 7 is provided on the top of the mounting plate 405. An auxiliary welding component 5 is provided at the bottom of the frame 1.

[0039] Specifically, during welding, the wire harness to be welded is placed on the placement plate 512, the cylinder 2 is activated, and the push rod is driven to move downward. The push rod presses down on the welding machine 704, which moves downward and drives the mounting plate 405 downward through the connecting frame 701. The mounting plate 405 drives the sealing plate 403 downward, the spring 402 is compressed, and the movable rod 401 slides downward along the rod hole of the frame 1. Under the limiting cooperation of the limiting rod 404, the sealing plate 403 moves downward steadily until the fan 407 moves down to connect with the dust collection bag 408 in the dust suction hole of the frame 1. During the downward movement of the sealing plate 403, the rope 510 fixed to it is pulled to move. The rope 510 pulls the movable plate 507 to move along the guide rod 505 towards the support seat 504. The spring 508 is compressed, and the movable plate 507 drives the placement plate 512 and the wire harness to be welded to move closer to the welding station simultaneously, realizing the automatic alignment of the wire harness.

[0040] As the fan 407 gradually descends to connect with the dust collection bag 408, the welding machine 704 descends synchronously with the mounting plate 405. When the welding machine 704 descends to contact the top of the movable plate 507, its downward pressure pushes the support base 504 downward. The support base 504 drives the lifting rod 502 to move downward within the sleeve 501, compressing the second spring 503. Under the limiting action of the second limiting rod 506, the support base 504 moves downward stably. When the support base 504 moves the bottom pressing head 516 down to contact and press the pressing switch 515, the fan 407 moves down to be fully connected with the dust collection bag 408, and one side of the movable plate 507 moves to contact the side wall of the support base 504. The wire harness is precisely positioned at the welding station. After the pressing switch 515 is triggered, the welding machine 704 is powered on and started. The welding machine 704 then performs welding on the wire harness.

[0041] During the welding process of welding machine 704, welding fumes containing tin dust are generated. At the same time, fan 407 is working. Under the negative pressure suction of fan 407, the welding fumes are drawn into the dust collection bag 408 for collection after being guided by fan 407.

[0042] The welding machine 704 is powered on and welding is fully connected to the fan 407 and dust collection bag 408 simultaneously. The moment the welding machine 704 starts welding, the fan 407 is already in the optimal dust collection state. It can immediately collect the tin-containing dust fumes generated by welding under negative pressure. It can quickly and accurately capture the fumes from the source of the fumes, which not only ensures the effective recovery of tin dust, but also avoids the unorganized diffusion of welding fumes from the root, greatly reducing dust pollution in the workshop. At the same time, it avoids the problems of delayed fume collection, insufficient capture or leakage that are common in traditional equipment, making the collection and treatment of welding fumes more timely and efficient.

[0043] Please see the appendix Figure 1 - AppendixFigure 7 The auxiliary welding assembly 5 includes a sleeve 501, the bottom end of which is fixedly connected to the bottom of the frame 1. A lifting rod 502 is slidably connected inside the sleeve 501. A support base 504 is fixedly connected to the top end of the lifting rod 502. A second spring 503 is fixedly connected to the bottom end of the lifting rod 502. The bottom end of the second spring 503 is fixedly connected to the bottom inner wall of the sleeve 501. Guide rods 505 are symmetrically fixedly connected to one side of the support base 504. Movable plates 507 are slidably connected to the outer walls of the two guide rods 505. The movable plates 507 are symmetrically fixedly connected to the side opposite to the support base 504. A spring 508 is sleeved on the outer wall of the guide rod 505. A wire hole 509 is opened on one side of the support base 504. A rope 510 is installed in the wire hole 509 of the support base 504. One end of the rope 510 is fixedly connected to the outer wall of the sealing plate 403, and the other end of the rope 510 is fixedly connected to the outer wall of the movable plate 507. An installation groove 511 is opened inside the movable plate 507. A damping shaft is rotatably connected in the installation groove 511 of the movable plate 507. A placement plate 512 is fixedly connected to the outer wall of the damping shaft. A handle 513 is fixedly connected to the bottom of the placement plate 512.

[0044] Specifically, during the downward movement of the sealing plate 403, the rope 510 fixed to it is pulled to move. The rope 510 pulls the movable plate 507 to move along the guide rod 505 towards the support seat 504. The spring 3 508 is compressed. The movable plate 507 drives the placement plate 512 and the wire harness to be welded to approach the welding station simultaneously, realizing the automatic alignment of the wire harness.

[0045] As the fan 407 gradually descends to connect with the dust collection bag 408, the welding machine 704 descends synchronously with the mounting plate 405. When the welding machine 704 descends to contact the top of the movable plate 507, its downward pressure pushes the support base 504 downward. The support base 504 drives the lifting rod 502 to move downward within the sleeve 501, compressing the second spring 503. Under the limiting action of the second limiting rod 506, the support base 504 moves downward stably. When the support base 504 moves the bottom pressing head 516 down to contact and press the pressing switch 515, the fan 407 moves down to be fully connected with the dust collection bag 408, and one side of the movable plate 507 moves to contact the side wall of the support base 504. The wire harness is precisely positioned at the welding station. After the pressing switch 515 is triggered, the welding machine 704 is powered on and started. The welding machine 704 then performs welding on the wire harness.

[0046] The auxiliary welding component 5 is the core structure that enables automatic alignment of the wire harness, precise triggering of welding, and coordinated operation with the dust collection and welding machine 704 components. Through mechanical force transmission, elastic component buffering, and precise coordination of the stroke of multiple components, it achieves seamless connection between the welding machine 704 and the dust collection operation. This ensures that the dust collection system is in the optimal negative pressure collection state while the welding machine 704 is welding, achieving rapid capture from the source of the flue gas and completely eliminating the problems of delayed or missed flue gas collection.

[0047] After the welding operation is completed, when the movable plate 507 returns to its initial position, hold the handle 513 to tilt the placement plate 512 downwards. A small amount of solder dross generated during the welding process can easily accumulate on the surface of the placement plate 512. When the placement plate 512 is tilted downwards, these debris can slide down with the tilted placement plate 512. There is no need to clean the placement plate 512 specially. The placement plate 512 can always be kept clean, avoiding the accumulation of debris from affecting the placement and positioning accuracy of subsequent wire harnesses, and reducing the daily cleaning workload of the equipment.

[0048] Please see the appendix Figure 5 - Appendix Figure 7 Appendix Figure 8 A pressing head 516 is fixedly connected to the bottom of the movable plate 507, and a vertical pole 514 is fixedly connected to the bottom of the frame 1. A pressing switch 515 is installed at the top of the vertical pole 514, and the pressing switch 515 is electrically connected to the welding machine 704.

[0049] Specifically, when the support base 504 moves the bottom pressing head 516 down to contact and press the pressing switch 515, the fan 407 moves down to be fully connected with the dust collection bag 408, and one side of the movable plate 507 moves to contact the side wall of the support base 504. The wire harness is precisely positioned at the welding station. After the pressing switch 515 is triggered, the welding machine 704 is powered on and started. The welding machine 704 then performs welding on the wire harness.

[0050] Through the mechanical force of the equipment linkage, the moment the pressing head 516 presses the pressing switch 515, the fan 407 and the dust collection bag 408 are fully connected, the movable plate 507 and the support base 504 are in contact, and the wire harness is accurately positioned at the welding station. At the same time, the welding machine 704 is energized to start welding. This achieves seamless connection between welding start-up, dust removal readiness, and wire harness positioning from the source, completely eliminating problems such as delayed welding fume collection and wire harness alignment deviation, and ensuring the best coordination between welding and dust removal operations.

[0051] Please see the appendix Figure 5 - Appendix Figure 6 The bottom of the frame 1 has a through hole, and a second limit rod 506 is slidably connected in the through hole of the frame 1. The top end of the second limit rod 506 is fixedly connected to the bottom of the support base 504.

[0052] Specifically, during the downward movement of the support seat 504, the second limiting rod 506 slides vertically along the inner wall of the through hole, providing strict vertical guidance for the support seat 504. This effectively prevents the support seat 504 from shifting, tilting, or rotating due to the downward pressure of the welding machine 704, the spring force, and other forces, ensuring that the support seat 504 always moves smoothly downward along the preset trajectory.

[0053] Please see the appendix Figure 1 - Appendix Figure 3 Appendix Figure 8 The fixing component 7 includes a connecting frame 701. The bottom of the connecting frame 701 is fixedly connected to the top of the mounting plate 405. A fixing ring 702 is fixedly connected to one end of the connecting frame 701. A welding machine 704 is installed inside the fixing ring 702. A screw hole is opened on the outer wall of the fixing ring 702. A locking bolt 703 is threaded into the screw hole of the fixing ring 702. One end of the locking bolt 703 abuts against the outer wall of the welding machine 704. An atomizing component 6 is installed on one side of the fixing ring 702.

[0054] Specifically, the threaded locking method of the locking bolt 703 is adopted. The welding machine 704 can be fixed and disassembled by simply turning the locking bolt 703. No additional special tools are required. The operation is simple and efficient, and it is convenient to install, disassemble and replace the welding machine 704. It is suitable for various installation and fixing requirements of welding machine 704.

[0055] Please see the appendix Figure 1 - Appendix Figure 3 A cylinder 2 is mounted on the top of the frame 1. A push rod is fixedly connected to the output end of the cylinder 2, and the bottom end of the push rod contacts the top of the welding machine 704.

[0056] Specifically, the cylinder 2 operates, driving the push rod to move downwards. The downward pressure of the push rod in cylinder 2 is the starting power for all the linkage actions of the equipment. By pushing the welding machine 704 downwards, the mounting plate 405 and the sealing plate 403 are moved downwards in sequence, thereby pulling the rope 510 to achieve automatic alignment of the wire harness and precise connection between the fan 407 and the dust collection bag 408. Finally, the press switch 515 is triggered to power on the welding machine 704 to start welding. The entire process of welding, alignment and dust removal can be driven by a single power source, making the linkage between the components more tight and eliminating the need for separate control of multiple power sources.

[0057] Please see the appendix Figure 1 - Appendix Figure 3 The atomizing component 6 includes a fixing rod 601, one end of which is fixedly connected to one side of a fixing ring 702, and the other end of which is equipped with an atomizing nozzle 602. A connecting pipe 603 is fixedly connected to the top of the atomizing nozzle 602.

[0058] Specifically, during the welding process, the atomizing nozzle 602 is connected to an external liquid source via a connecting pipe 603. The atomizing nozzle 602 sprays atomized liquid droplets into the welding fume area. These droplets combine with fine tin dust particles in the fume, increasing their weight and causing them to agglomerate into larger particles. These larger particles are then quickly drawn into the dust collection bag 408 by the negative pressure of the fan 407 for collection. This compensates for the inadequacy of a single dust collection bag 408 in capturing micro-particle dust, achieving comprehensive recovery of tin dust of different particle sizes and greatly improving the overall dust collection rate. Simultaneously, the atomized droplets form an atomization barrier in the welding fume area, which... It effectively suppresses the unorganized diffusion of tin dust during the welding process, reducing the possibility of dust escaping into the workshop environment. Together with the negative pressure collection of the fan 407, it forms a dual dust control effect, further reducing dust pollution in the workshop from the source and improving the on-site environment for welding operations. In addition, the atomized droplets sprayed by the atomizing nozzle 602 can effectively eliminate static electricity generated by dryness in the welding environment, neutralize the static charge on tin dust particles and the surface of equipment and workshop components, and prevent dust from being difficult to clean due to static electricity adsorption on the inner wall of equipment or workshop components, further improving the thoroughness of dust collection and reducing the safety hazards caused by static electricity.

[0059] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
