Description

Technical Field

[0001] This invention belongs to the field of machining technology, and in particular relates to a welding device for machining. Background Technology

[0002] In machining processes, it is often necessary to lap weld steel plates, such as butt welding of low-carbon steel plates. This involves stacking two regularly sized Q235 steel plates and welding them together to achieve a lap weld. This welding method is commonly used for connecting thicker steel plates such as vehicle frames and beams.

[0003] Currently, most lap welding machines on the market have fixed welding stations, which only provide simple support for the welded parts. However, in actual welding operations, workers often need to weld different parts of the workpiece. Since the welding station cannot be rotated or adjusted, workers have to frequently move their bodies or adjust the position of the workpiece, which not only increases labor intensity but also easily leads to welding position deviations, affecting welding quality. Weld slag is a hard and brittle substance that covers the weld metal after welding. Its formation is directly related to the cooling and solidification of molten slag during the welding process and usually needs to be removed mechanically or manually. Since weld slag cannot completely fall off on its own, proper cleaning is crucial. Common cleaning methods mainly include tapping (such as using a slag hammer) and mechanical methods (such as using a wire brush or grinding wheel). Cleaning should be carried out after the weld area has naturally cooled to a suitable temperature to avoid damage to the hot molten pool or increased cleaning difficulty.

[0004] For example, Chinese utility model patent publication number CN2041225U discloses an electromagnetic weld seam cleaning machine. This machine uses the voltage between the welding torch and the workpiece as its power source and integrates functions such as a wire brush, head, hand shovel, and electric or pneumatic wire wheel. Another example is Chinese utility model patent publication number CN2327491Y, which discloses a three-hole high-speed air gouging torch. This torch consists of a torch body and a carbon rod chuck. The chuck contains a spring and a top ball, and the lower part of the carbon rod core has three air outlets arranged in a straight line. All of these patents require manual operation for weld slag cleaning, resulting in low work efficiency. Summary of the Invention

[0018] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0019] This invention provides a welding device for machining, particularly for lap welding of regular steel plates. For example... Figure 1-8As shown, the welding equipment for machining includes: a frame 1; an operating table 2 fixed on the frame 1; a protective shell 3 fixed on the operating table 2, the protective shell having an operating window 53; a welding host 4 mounted on the frame 1; a welding torch 5 used in conjunction with the welding host 4; an assembly plate 6 fixed inside the protective shell 3, with a space between the bottom of the assembly plate and the bottom of the protective shell, and a welding station 7 mounted on the assembly plate 6 via a rotation adjustment mechanism that can rotate and adjust around its own axis, the welding station including a workpiece placement area in the middle and a downwardly inclined area around the workpiece placement area. An inclined area; a slag cleaning mechanism disposed in the inclined area, the slag cleaning mechanism comprising: a wedge block 46 fixedly connected to the surface of the inclined area; an opening groove 47 centrally located on one inclined surface of the wedge block; two rolling elements 48 located on the surface of the wedge block and on both sides of the opening groove; a horizontal shaft 49 fixedly connected between the two rolling elements; a sliding groove 50 located on the upper surface of the inclined area and corresponding to the projection area of ​​the opening groove; a slider 51 slidingly engaged within the sliding groove; and a tension spring 52 fixedly connected between the horizontal shaft and the slider.

[0020] In this embodiment, the workpiece to be welded is placed on the surface of the welding station 7 on the assembly plate 6. The equipment is then started, and the welding station 7 is rotated around its own axis according to the welding requirements, so that the part of the workpiece to be welded is rotated to a suitable operating position. Next, the welding torch 5 is inserted through the operating window, and the welding operation is performed on the workpiece using the welding torch 5. After rotating the welding station a certain number of times, the welding is completed. Because the rotation speed is slow and the time is short, the slag cleaning mechanism does not activate. Figure 9 , Figure 10 As shown, after cooling for a period of time, the welding station is continuously rotated at a certain speed. Due to the influence of centrifugal force and gravity, the slider moves away from the workpiece placement area. Through the tension spring, the rotating shaft and rolling body move to the high point of the wedge block. When the elastic restoring force of the tension spring is greater than the influence of centrifugal force and gravity, the rolling body rolls down from the high point of the wedge block and impacts the weld seam at the corresponding position due to inertia. This process is repeated to knock off the welding slag around the weld seam. There can be one, two or more welding slag cleaning mechanisms, which are evenly distributed in the inclined area. In this way, there is no need for manual knocking of welding slag, and the welding slag is automatically peeled off. The peeled welding slag will fall onto the assembly plate along the inclined area.

[0021] The welding station 7 is designed to rotate and adjust around its own axis, allowing workers to perform welding operations on different parts of the workpiece without frequently moving their bodies or adjusting the workpiece position, thus reducing the labor intensity of workers; the limiting mechanism can limit and fix the workpiece, preventing displacement of the workpiece during welding, which helps to reduce the probability of welding position deviation and plays a positive role in improving welding quality; the protective shell 3 can provide a certain degree of protection for the welding area and reduce the impact of welding spatter on the outside world.

[0022] The combined use of the welding host 4 and the welding torch 5 provides stable welding energy for welding operations, ensuring the normal operation of welding work. The welding fume collection and treatment mechanism collects and purifies the welding fumes, which helps to improve the welding working environment and reduce the impact of welding fumes on workers. The frame 1 and the operating table 2 provide stable support for each component of the equipment, so that each component maintains a relatively stable positional relationship during operation, which helps to improve the overall stability of the equipment operation and provides a guarantee for long-term welding operations.

[0023] In a further preferred embodiment of the present invention, the rotation adjustment structure includes: a first rotating rod 9 rotatably mounted at the bottom center of the assembly plate 6 via a bearing, the top of the first rotating rod 9 being fixedly connected to the bottom center of the welding station 7; a first motor 10 fixed to the bottom of the assembly plate 6; two first bevel teeth 11 respectively fixed to the output shaft of the first motor 10 and the bottom of the first rotating rod 9 and meshing with each other; an annular plate 12 fixed on the assembly plate 6 and surrounding the first rotating rod 9, the upper surface of the annular plate having an annular groove; and support columns 13 symmetrically fixed at both ends of the bottom of the welding station 7 about the first rotating rod, the bottom end of the support column 13 being provided with a rolling element adapted to the annular groove on the annular plate 12, the rolling element rollingly contacting the annular groove.

[0024] In this embodiment, when it is necessary to adjust the angle of the welding station 7, the first motor 10 at the bottom of the assembly plate 6 is started. The output shaft of the first motor 10 drives the first bevel gear 11 fixed thereto to rotate. Since the two first bevel gears 11 mesh with each other, they drive the first rotating rod 9 fixed to the other first bevel gear 11 to rotate around the bearing. When the first rotating rod 9 rotates, it drives the welding station 7 fixed at the top to rotate synchronously. During the rotation of the welding station 7, the rolling element at the bottom end of the support column 13 symmetrically fixed at its bottom rolls along the annular groove on the ring plate 12 until the welding station 7 rotates to the required angle. Then the first motor 10 is turned off to stop the adjustment. The structure of the first motor 10 driving the first rotating rod 9 to rotate through the first bevel gear 11 provides stable power for the rotation of the welding station 7, making the rotation adjustment process of the welding station 7 smoother. The cooperative design of the support column 13 and the ring plate 12 can provide auxiliary support for the welding station 7, preventing the welding station 7 from tilting when rotating or carrying workpieces, and helping to maintain the horizontal state of the welding station 7. The rolling contact method between the rolling element and the ring groove reduces the friction between the support column 13 and the ring plate 12, reduces component wear, and also makes the rotation operation of the welding station 7 smoother. This rotary adjustment structure eliminates the need for manual operation of the welding station 7, reducing manual steps and lowering the operational difficulty for workers. The coordinated operation of each component enables multi-angle rotation adjustment of the welding station 7, meeting the workpiece angle requirements in different welding scenarios and providing convenience for welding operations. In addition, the continuously rotating welding station can activate the slag cleaning mechanism to automatically remove the slag.

[0025] In a further preferred embodiment of the present invention, a limiting mechanism is further included, the limiting mechanism comprising: a telescopic drive component fixed to the inner wall of the top of the protective shell 3, the telescopic drive component being an electric telescopic rod 14; a first groove block 15 fixed to the electric rod end of the electric telescopic rod; an assembly block 16 fixed to the first groove block 15 by bolts, the bottom ends of the assembly block extending with two support arms; a rotating shaft 17 rotatably mounted between the two support arms by bearings; a plug-in block 18 fixed to the bottom end of the rotating shaft 17; a second groove block 19 fixed to the plug-in block 18 by bolts; and a limiting plate 8 fixed to the bottom of the second groove block 19, the bottom surface of the limiting plate 8 being able to fit against the surface of the workpiece to be welded.

[0026] In this embodiment, according to the shape and size of the workpiece to be welded, a suitable limiting plate 8 and a corresponding second groove block 19 and assembly block 16 are selected; the assembly block 16 is fixed in the first groove block 15 with bolts, and then the second groove block 19 is fixed on the plug-in block 18 with bolts to complete the assembly and adaptation of the limiting components; then the electric telescopic rod 14 is activated, and its push rod drives the first groove block 15 to move down, which in turn drives the limiting plate 8 to move down through the assembly block 16, the rotating shaft 17, the plug-in block 18, and the second groove block 19 until the bottom surface of the limiting plate 8 is in contact with the surface of the workpiece, and the electric telescopic rod 14 is closed to achieve the limiting; when the welding station 7 rotates, the rotating shaft 17 rotates synchronously with the welding station 7 to maintain the limiting state; The first groove block 15 and the assembly block 16, and the plug-in block 18 and the second groove block 19 are connected by bolts in a detachable manner. This allows workers to replace the appropriate limiting plate 8 and related components according to different workpieces without replacing the entire limiting mechanism, thus improving the adaptability of the mechanism to different workpieces. The bolt connection is simple to disassemble and assemble without complicated tools, shortening the time for replacing limiting components and reducing the impact on welding efficiency. When the limiting plate 8, the second groove block 19, or the assembly block 16 is worn, the damaged parts can be disassembled and replaced individually, avoiding the waste caused by replacing the whole thing.

[0027] The limiting plate 8 fits snugly against the workpiece surface, reducing the probability of workpiece displacement during welding and providing stable conditions for welding operations. The electric telescopic rod 14 drives the limiting plate 8 to adjust its height, reducing the need for manual adjustment and lowering the labor intensity of workers. The detachable connection design not only improves the adaptability of the mechanism but also facilitates the later inspection and maintenance of components, extending the overall service life of the limiting mechanism and providing support for the long-term stable operation of the equipment.

[0028] In a further preferred embodiment of the present invention, a welding fume collection and treatment mechanism is also included, comprising: a horizontally fixed gas collecting pipe 20 on the inner wall of the protective shell 3, wherein at least two gas collecting hoods 21 facing the welding station 7 are fixedly connected to the gas collecting pipe 20; a mounting box 22 fixed to the top of the protective shell 3, wherein a vertical partition is provided inside the mounting box to divide the mounting box into a filter chamber 23 and an exhaust chamber 24, and the partition has a connecting hole; a conduit 25 fixedly connected between the top of the filter chamber 23 and the gas collecting pipe 20 and passing through the top of the protective shell; a filter plate 26 disposed in the filter chamber 23, wherein the filter plate 26 is used to filter particulate matter in the welding fume; a second rotating rod 27 rotatably mounted to the side wall of the exhaust chamber 24 via a bearing, wherein one end of the second rotating rod 27 is located inside the exhaust chamber and is fixedly provided with a fan blade 28 for driving airflow, and the other end of the second rotating rod is located outside the exhaust chamber and is drivenly connected to a driving component; and an exhaust hole opened on the side wall of the exhaust chamber 24.

[0029] In this embodiment, before starting the welding torch 5 for welding operations, the drive component associated with the second rotating rod 27 is activated, causing the second rotating rod 27 to rotate around the bearing. When the second rotating rod 27 rotates, it drives the fan blade 28 fixed on it to rotate synchronously. The rotation of the fan blade 28 generates negative pressure, which causes the welding fumes generated inside the protective shell 3 to be sucked into the gas collection hood 21. The welding fumes enter the gas collection pipe 20 through the gas collection hood 21, and are then transported to the filter chamber 23 in the mounting box 22 through the conduit 25. After being filtered by the filter plate 26 in the filter chamber 23, some particulate matter is removed. Then, the welding fumes enter the exhaust chamber 24 through the connecting hole between the filter chamber 23 and the exhaust chamber 24, and are finally discharged from the exhaust hole on the side of the exhaust chamber 24 away from the filter chamber 23. At least two gas collection hoods 21 facing the welding station 7 are installed on the gas collection pipe 20, which can expand the range of welding fume collection and reduce welding fume residue in the protective shell 3; the filter plate 26 is installed in the filter chamber 23, which can filter particulate matter in the welding fume and reduce the particulate matter content in the exhaust gas; the second rotating rod 27 is rotatably connected to the exhaust chamber 24 through the bearing, and forms a stable airflow channel with the fan blade 28 to ensure the smoothness of the welding fume collection and transportation process; the installation box 22 is divided into the filter chamber 23 and the exhaust chamber 24, so that the welding fume collection, filtration and exhaust processes are carried out in separate areas, improving the orderliness of welding fume treatment.

[0030] The operation of the welding fume collection and treatment mechanism can reduce the diffusion of welding fumes inside the protective shell 3 during welding operations, creating a relatively good operating environment for workers. The filter plate 26 in the filter chamber 23 filters the welding fumes, which helps to reduce the impact of the exhaust gas on the external environment. The entire mechanism forms a closed welding fume transport path through components such as the gas collection hood 21, gas collection pipe 20, and duct 25, reducing leakage of welding fumes during transport and improving the efficiency of welding fume collection and treatment.

[0031] In a further preferred embodiment of the present invention, the driving component includes: a second motor 29 fixed on the operating table 2 and located outside the protective shell, the output axis of the second motor extending horizontally along the side wall of the protective shell; a first transmission rod 30 vertically rotatably mounted on the side wall of the protective shell 3 via a bearing seat; two second bevel teeth 31 respectively fixed on the first transmission rod 30 and the output shaft of the second motor 29 and meshing with each other; and two third bevel teeth 32 respectively fixed on the top of the first transmission rod 30 and the other end of the second rotating rod 27 and meshing with each other.

[0032] In this embodiment, when the welding fume collection and treatment mechanism needs to be activated, the second motor 29 fixed on the operating table 2 is activated, and the output shaft of the second motor 29 drives the second bevel gear 31 fixed thereto to rotate. Since the two second bevel gears 31 mesh with each other, the rotating second bevel gear 31 drives the first transmission rod 30 fixed to the other second bevel gear 31 to rotate around the bearing seat. When the first transmission rod 30 rotates, it drives the third bevel gear 32 fixed thereto to rotate synchronously. Since the third bevel gear 32 meshes with the third bevel gear 32 on the second rotating rod 27 in the welding fume collection and treatment mechanism, it drives the second rotating rod 27 to rotate, providing power to the fan blades 28 to drive the airflow. The second motor 29, as a power source, can provide stable power output to the transmission structure, ensuring the continuity of the entire transmission process. The first transmission rod 30 is rotatably mounted on the protective shell 3 through the bearing seat, making the first transmission rod 30 rotate more smoothly and reducing transmission deviation caused by shaking. The meshing of the second bevel tooth 31 and the third bevel tooth 32 realizes the transmission of power between the second motor 29 and the second rotating rod 27. Moreover, the bevel tooth transmission can change the direction of power transmission to adapt to the installation position requirements of the second motor 29 and the second rotating rod 27.

[0033] In a further preferred embodiment of the present invention, the filter plate 26 in the filter chamber 23 has a multi-layer structure, which includes a pre-filter, an activated carbon filter and a HEPA high-efficiency filter from top to bottom, and the filter plate 26 is detachably connected to the inner wall of the filter chamber 23.

[0034] In this embodiment, before the welding fume collection and treatment mechanism is put into use, the filter plate 26 is assembled into the filter chamber 23 in the following order from top to bottom: pre-filter, activated carbon filter, and HEPA high-efficiency filter, so that the filter plate 26 and the inner wall of the filter chamber 23 form a detachable connection. When the welding fume enters the filter chamber 23, it first passes through the pre-filter to intercept larger particles of welding fume, then passes through the activated carbon filter to adsorb some harmful gases, and finally passes through the HEPA high-efficiency filter to filter fine particles. After the filter plate 26 has been used for a period of time, it can be removed from the inner wall of the filter chamber 23 for cleaning or replacement, and then reassembled into the filter chamber 23 to continue the welding fume filtration operation. The filter plate 26 adopts a multi-layer structure of pre-filter, activated carbon filter and HEPA high-efficiency filter, which can classify and treat welding fumes, gradually remove different types of pollutants, and improve the welding fume filtration effect. The pre-filter can intercept larger particles first, preventing them from clogging subsequent filters and extending the service life of the activated carbon filter and HEPA high-efficiency filter. The activated carbon filter can adsorb some harmful gases in welding fumes, reducing harmful components in the exhaust gas, while the HEPA high-efficiency filter can filter fine particulate matter, further reducing the pollutant content in the exhaust gas.

[0035] In a further preferred embodiment of the present invention, a sealing door is fitted on one side of the filter chamber 23 via a hinge, and a door lock is provided on the sealing door.

[0036] In this embodiment, when it is necessary to clean or replace the filter plate 26 in the filter chamber 23, first open the door lock on the sealing door, then rotate the sealing door around the hinge to expose the inside of the filter chamber 23; then disassemble, clean or replace the filter plate 26. After completion, rotate the sealing door back to its original position around the hinge, close and lock the door lock on the sealing door to restore the filter chamber 23 to a sealed state; during the operation of the welding fume collection and treatment mechanism, keep the sealing door in the closed and locked state to ensure that the welding fume is stably filtered in the filter chamber 23.

[0037] In a further preferred embodiment of the present invention, the bottom of the frame 1 is symmetrically fixed with supporting feet, and one side of the frame 1 is fixed with a bracket for placing the welding host 4.

[0038] In this embodiment, during the equipment installation phase, the frame 1 is placed in a preset working position, and the symmetrically fixed support feet at the bottom of the frame 1 directly contact the ground to provide support for the frame 1; then the welding host 4 is placed on a bracket fixed on one side of the frame 1 to ensure that the welding host 4 is stably placed on the surface of the bracket, thus completing the placement of the welding host 4; during the overall operation of the equipment, the support feet continuously support the frame 1, while the bracket continuously carries the welding host 4, maintaining the relative position stability of each component of the equipment; The support feet are symmetrically fixed at the bottom of the frame 1, which can make the frame 1 bear the force evenly, reduce the probability of the frame 1 tilting due to uneven force, and ensure the horizontal state of the upper components such as the operating table 2 and the protective shell 3. The support feet are in contact with the ground, which can reduce the direct friction between the bottom of the frame 1 and the ground, and avoid wear and tear on the bottom of the frame 1 due to long-term contact with the ground.

[0039] In a further preferred embodiment of the present invention, a placement rack 45 is fixed on one side of the protective shell 3. The placement rack 45 is used to place the welding torch 5, and a limiting groove adapted to the shape of the welding torch 5 is provided on the placement rack 45. A buffer pad layer is provided on the inner wall of the limiting groove.

[0040] In this embodiment, when the welding operation is paused or completed, the worker places the welding torch 5 on the placement rack 45, aligns the body of the welding torch 5 with the limiting groove on the placement rack 45 that matches the shape of the welding torch 5, and slowly inserts it so that the welding torch 5 fits the inner wall of the limiting groove, thus completing the placement of the welding torch 5; when welding needs to continue, the welding torch 5 can be directly removed from the limiting groove to carry out subsequent operations. The whole process does not require any additional fixing steps and is convenient to operate.

[0041] In a further preferred embodiment of the present invention, the rolling element is a ball bearing, and the inner wall of the annular groove on the annular plate 12 is provided with a wear-resistant coating, which is a ceramic coating.

[0042] In this embodiment, the ball bearing acts as a rolling element, converting the sliding friction between the support column 13 and the annular groove into rolling friction, reducing the frictional resistance between them, making the welding station 7 rotate more smoothly, and reducing the power loss of the first motor 10; the spherical structure of the ball bearing can flexibly adapt to the arc trajectory of the annular groove, ensuring that the support column 13 always maintains stable contact with the annular groove during the rotation of the welding station 7, providing continuous auxiliary support for the welding station 7, and preventing the welding station 7 from tilting or shaking.

[0043] To further improve the performance of this device, in addition to the above-mentioned solutions, this solution also includes the following embodiments: In another embodiment of the present invention, a slag collection mechanism is further included, comprising: slag discharge holes formed on the assembly plate, the slag discharge holes being evenly distributed around the periphery of the inclined area; a funnel 33 fixed to the bottom of the protective shell 3; a slag discharge pipe 34 fixedly connected to the bottom of the funnel 33; a collection box 35 disposed on the frame 1 and located below the slag discharge pipe 34, the collection box 35 being capable of containing a cooling medium; and a wire mesh basket 36 placed inside the collection box 35, the wire mesh basket 36 being used to receive the slag discharged from the slag discharge pipe 34, and the wire mesh basket 36 being in contact with the cooling medium inside the collection box 35.

[0044] In this embodiment, before the welding operation begins, an appropriate amount of cooling medium is injected into the collection box 35 on the frame 1, and the wire mesh basket 36 is placed in the collection box 35, ensuring that the wire mesh basket 36 can contact the cooling medium. After welding is completed, the generated welding slag is peeled off by the welding slag cleaning mechanism and falls into the slag discharge hole along the inclined area. It is then received by the funnel 33 fixed inside the protective shell 3 and located below the welding station 7. The received welding slag slides down the inner wall of the funnel 33 and is transported to the wire mesh basket 36 in the collection box 35 through the slag discharge pipe 34 fixedly connected to the bottom of the funnel 33. After the welding slag enters the wire mesh basket 36, it comes into contact with the cooling medium in the collection box 35, completing the collection and preliminary treatment of the welding slag. After the operation is completed, the wire mesh basket 36 can be removed from the collection box 35 for subsequent cleaning of the collected welding slag. The slag discharge pipe 34 connects the funnel 33 and the collection box 35, providing a directional conveying channel for the welding slag and preventing the welding slag from scattering during the conveying process; the cooling medium in the collection box 35 can cool down the welding slag entering the wire mesh basket 36, reducing the risk of safety hazards caused by high-temperature welding slag; the wire mesh basket 36 can separate the welding slag from the cooling medium, making it convenient to clean the welding slag in a centralized manner without direct contact with the cooling medium.

[0045] In another embodiment of the present invention, the slag collection mechanism further includes an anti-clogging structure, which includes: a mounting shell 37 fixed to the bottom of the assembly plate 6; a third rotating rod 38 rotatably mounted on the bottom of the mounting shell 37 via bearings, the top end of the third rotating rod being located inside the mounting shell and the bottom end being located outside the mounting shell; an auger 39 fixed to the bottom end of the third rotating rod 38 via a coupling, the auger 39 extending into the slag discharge pipe 34; a connecting frame 40 with one end fixed to the portion of the third rotating rod 38 located outside the mounting shell; a first scraper 41 fixed to the other end of the connecting frame 40, the first scraper 41 being in contact with the inner wall of the funnel 33; a second transmission rod 42 rotatably mounted on the side wall of the protective shell 3 via bearings, one end of the second transmission rod 42 being connected to the output shaft of the second motor 29, and the other end of the second transmission rod extending into the side wall of the mounting shell; and two fourth bevel teeth 43 respectively fixed to the other end of the second transmission rod 42 and the third rotating rod 38 and meshing with each other.

[0046] In this embodiment, when the welding operation starts, the second transmission rod 42, which is connected to the output shaft of the second motor 29, rotates as the second motor 29 starts. Since the second transmission rod 42 meshes with the fourth bevel tooth 43 on the third rotating rod 38, the second transmission rod 42 drives the third rotating rod 38 to rotate around the bearing on the mounting shell 37. When the third rotating rod 38 rotates, on the one hand, it drives the auger 39 extending into the slag discharge pipe 34 to rotate synchronously through the coupling, pushing the welding slag in the slag discharge pipe 34 downward. On the other hand, it drives the connecting frame 40 fixed on it to rotate, and the connecting frame 40 drives the first scraper 41 to rotate along the inner wall of the funnel 33 to scrape off the welding slag attached to the inner wall of the funnel 33. After the welding operation is completed, the anti-blocking structure components stop operating synchronously as the second motor 29 stops. The auger 39 extends into the slag discharge pipe 34, and its rotation can push the welding slag in the slag discharge pipe 34, reducing the probability of welding slag accumulating and clogging in the slag discharge pipe 34; the first scraper 41 is in contact with the inner wall of the funnel 33, and can continuously scrape off the welding slag attached to the inner wall of the funnel 33 when it rotates with the connecting frame 40, avoiding the welding slag from accumulating on the inner wall of the funnel 33 and ensuring smooth slag discharge from the funnel 33; the cooperation between the second transmission rod 42 and the fourth bevel gear 43 realizes the transmission of power from the second motor 29 to the third rotating rod 38, eliminating the need to set up a separate power source for the anti-clogging structure, simplifying the structure and reducing equipment costs. In another embodiment of the present invention, a cleaning structure for cleaning the welding station 7 is further included, the cleaning structure comprising: a plurality of second scrapers 44 fixed to the bottom of the inclined area by connecting columns, the second scrapers 44 corresponding to slag discharge holes.

[0047] In this embodiment, when the welding station 7 rotates under the drive of the first rotating rod 9, the welding station 7 simultaneously drives the second scraper 44 at the bottom to rotate along the upper surface of the assembly plate 6. During the rotation of the second scraper 44, the welding slag accumulated on the upper surface of the assembly plate 6 is scraped towards the slag discharge hole. The scraped welding slag falls into the corresponding funnel 33 below through the slag discharge port, and then enters the welding slag collection mechanism to complete the subsequent processing. When the welding station 7 continues to rotate, the second scraper 44 can continuously clean the upper surface of the assembly plate 6 until the welding operation is completed.
