Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, and in particular to an automatic welding robot that prevents welding slag from falling onto the workpiece. Background Technology

[0002] An automated welding robot is an industrial robot used for automated welding operations, widely applied in manufacturing and other fields. It mainly consists of a robotic arm, a welding power source, a control system, and a wire feeding mechanism. The robotic arm has multiple degrees of freedom, enabling precise positioning and manipulation of welding tools, mimicking the movements of a human welder, and performing welding operations on various workpieces and in different working environments. The welding power source provides stable current and voltage for welding, ensuring weld quality. The control system is the robot's "brain," precisely controlling the robotic arm's movement trajectory, welding speed, welding parameters, etc., through preset programs, and also enabling collaborative work with other equipment. The wire feeding mechanism is responsible for accurately delivering the welding wire to the welding area.

[0003] Automatic welding robots have advantages such as stable welding quality, high production efficiency, and strong repeatability. They can greatly reduce labor costs and labor intensity, improve the level of automation in production and product quality, and play an important role in industries such as automobile manufacturing, shipbuilding, and metal processing.

[0004] The existing technology has the following drawbacks:

[0005] In welding operations, a high-temperature electric arc melts the metal and forms a molten pool. Metal oxides, flux residues, and impurities on the surface of the molten pool form welding slag after cooling. In traditional processes, this welding slag is scattered on the workpiece surface by splashing or falling off naturally, which can cause damage to the workpiece surface, obstacles to subsequent processing, and a decline in functional performance. Moreover, after a period of time, this welding slag will completely solidify, which increases the difficulty of cleaning. Summary of the Invention

[0006] In view of the problem of welding slag splattering everywhere during welding in existing technology, an automatic welding robot that avoids welding slag falling onto the workpiece is proposed.

[0007] This application provides an automatic welding robot that prevents welding slag from falling onto the workpiece. Its purpose is to collect the welding slag and prevent it from splashing everywhere.

[0008] The technical solution of the present invention is: an automatic welding robot that avoids welding slag falling onto the workpiece, including a base, a robotic arm disposed on the top of the base, a welding head disposed on the end of the robotic arm away from the base, and an adsorption device disposed on the outside of the welding head.

[0009] The adsorption device specifically includes an adsorption hood located at the end of the welding head away from the robotic arm, an adsorption cavity opened on the inner side of the wall of the adsorption hood, an adsorption hole opened on the inner side of the adsorption hood and communicating with the adsorption cavity, an outer pipe set on the outer side of the adsorption hood, a rotating disk set inside the adsorption hood, a connecting hole set through the top of the rotating disk, a cleaning component set at the bottom of the rotating disk, and a power component set at the top of the rotating disk.

[0010] The adsorption hood specifically includes a lower hood and an upper connector. The adsorption chamber specifically includes a covering channel and a flow channel respectively opened on the inner side of the walls of the lower hood and the upper connector. An array of adsorption holes is distributed on the inner side of the lower hood. A through hole communicating with the inner space of the lower hood is opened at the connection between the covering channel and the flow channel. The rotating disk enters the covering channel through the through hole. The outer pipe is connected to the flow channel. The cleaning component is attached to the inner wall of the lower hood and the covering channel.

[0011] Furthermore, the cleaning component specifically includes an outer scraper and an inner scraper disposed at the bottom of the rotating disk. The outer scraper is attached to the inner wall of the lower cover, and the inner scraper is attached to the inner wall of the covering channel near the outer contour.

[0012] Furthermore, a reinforcing hook is provided at the end of the outer scraper away from the rotating disk. The reinforcing hook is in the shape of a "J" and is hooked onto the edge of the lower cover away from the upper connector.

[0013] Furthermore, a reinforcing block is provided at the end of the inner scraper away from the rotating disk, and the reinforcing block is in contact with the inner wall of the covering channel near the inner contour.

[0014] Furthermore, the power assembly specifically includes a rotating groove opened on the inner side of the upper connector, a rotating wheel disposed on the inner side of the rotating groove, a reinforcing hook disposed on the outer side of the rotating wheel, and an inflow channel and an outflow channel opened between the rotating groove and the flow channel.

[0015] The inflow channel extends to the outside of the adsorption hood, and the outer pipe extends through the inflow channel and connects to the rotating groove.

[0016] Furthermore, the through paths of the inflow and outflow channels are tangent to the inner wall of the rotating groove.

[0017] Furthermore, the lower cover has a frustum-shaped cross section, the opening diameter of the lower cover near the upper connector is smaller than the opening diameter of the other end, and the upper connector has a cylindrical cross section.

[0018] Furthermore, the adsorption cover is assembled from two symmetrical parts, with the adsorption cover fitted onto the fixing sleeve at the end of the upper connector away from the lower cover.

[0019] Furthermore, an adjustment assembly is provided on the outer side of the welding head. The adjustment assembly specifically includes a fixing ring disposed on the outer side of the welding head, a mounting groove opened at the end of the upper connector away from the lower cover, a mounting ring disposed on the inner side of the mounting groove, and an adjustment spring disposed between the mounting ring and the fixing ring.

[0020] The beneficial effects of this invention are:

[0021] 1. By setting up an adsorption device, the lower cover covers the outside of the welding rod. When welding, the suction pump is started first, and the splashed welding slag is guided by the airflow into the lower cover through the adsorption hole. Then, the welding slag flows out from the outer pipe. This can collect the welding slag and prevent it from splashing onto the workpiece, thus ensuring the quality of the workpiece. At the same time, the cleaning component scrapes off the welding slag adhering to the inner wall of the lower cover and the covering channel, so that welding slag can continue to adhere to the inner wall of the lower cover and the covering channel, enhancing the collection effect of welding slag.

[0022] 2. By setting up cleaning components, the outer scraper removes the welding slag adhering to the inner wall of the lower cover, and the inner scraper removes the welding slag adhering to the inner wall of the covering channel. This ensures that both the lower cover and the covering channel have the ability to continuously retain welding slag, further enhancing the collection effect of welding slag. At the same time, the reinforcing hook ensures that the outer scraper is in close contact with the lower cover for a long time, and the reinforcing block ensures that the inner scraper is in close contact with the covering channel for a long time. This prevents the end of the outer and inner scrapers away from the rotating disk from loosening after long-term operation and no longer being in close contact with the lower cover or the covering channel.

[0023] 3. By setting up a power component, when the suction pump is started, the airflow pushes the fan blades and rotating wheel to rotate, thereby causing the rotating disc to drive the cleaning component to rotate for cleaning. This makes the collection program and the cleaning program work together more perfectly, ensuring the stable operation of the equipment.

[0024] 4. By setting an adjustment component, the adsorption hood is fixed to the mounting ring, and the adsorption hood and adsorption hole are slidably installed on the outside of the welding head. In this way, when there is obstruction around the welding point, the adsorption hood can move a certain distance along the welding head to avoid it, thus making the equipment more adaptable.

[0041] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0042] Example 1, referring to Figure 1-14The first embodiment of the present invention provides an automatic welding robot that prevents welding slag from falling onto the workpiece, including a base 1, a robotic arm 2 disposed on the top of the base 1, a welding head 3 disposed at one end of the robotic arm 2 away from the base 1, and an adsorption device 5 disposed on the outside of the welding head 3.

[0043] The adsorption device 5 specifically includes an adsorption cover 51 located at the end of the welding head 3 away from the robotic arm 2, an adsorption cavity 52 opened on the inner side of the wall of the adsorption cover 51, a plurality of adsorption holes 53 opened on the inner side of the adsorption cover 51 and communicating with the adsorption cavity 52, an outer pipe 54 located on the outer side of the adsorption cover 51, a rotating disk 55 located inside the adsorption cover 51, a connection hole 56 passing through the top of the rotating disk 55, a cleaning component 57 located at the bottom of the rotating disk 55, and a power component 58 located at the top of the rotating disk 55.

[0044] Specifically, one end of the robotic arm 2 is fixed to the base 1 by bolts, and the other end is fixed to the welding head 3 by bolts. The welding head 3 is provided with a welding rod on its inner side. The adsorption hood 51 specifically includes a lower cover 511 and an upper connector 512. The adsorption chamber 52 specifically includes a covering channel 521 and a flow channel 522 respectively opened on the inner side of the walls of the lower cover 511 and the upper connector 512. The lower cover 511 has a frustum-shaped cross section. The opening diameter of the lower cover 511 near the upper connector 512 is smaller than the opening diameter of the other end. The upper connector 512 has a cylindrical cross section. This can improve the collection effect of the adsorption hood 51 on the welding slag. The adsorption hood 51 is sleeved on the outside of the welding head 3. The covering channel 521 and the flow channel 522 are connected.

[0045] The adsorption holes 53 are arrayed inside the lower cover 511. A through hole communicating with the inner space of the lower cover 511 is opened at the connection between the coverage channel 521 and the flow channel 522. The outer pipe 54 is connected to the suction pump through a hose. The rotating disk 55 is annular and concentric with the adsorption cover 51. The rotating disk 55 is sleeved on the outside of the welding head 3. The rotating disk 55 enters the coverage channel 521 through the through hole. The through hole and the rotating disk 55 are perfectly matched. The rotating disk 55 is rotatably installed at the through hole. The connecting hole 56 connects the coverage channel 521 and the flow channel 522. The outer pipe 54 communicates with the flow channel 522. The cleaning component 57 is attached to the inner wall of the lower cover 511 and the coverage channel 521. The adsorption cover 51 is assembled from two symmetrical parts. The upper connector 512 is fitted with a fixing sleeve 59 at the end away from the lower cover 511 to fix the two adsorption cover 51 parts.

[0046] By setting up the adsorption device 5, the lower cover 511 covers the outside of the welding rod. When welding, the suction pump is started first, and the splashed welding slag is guided by the airflow into the lower cover 511 through the adsorption hole 53. Then, the welding slag flows out from the outer pipe 54. In this way, the welding slag can be collected, avoiding the welding slag from splashing onto the workpiece and ensuring the quality of the workpiece. At the same time, the cleaning component 57 scrapes off the welding slag attached to the inner wall of the lower cover 511 and the covering channel 521, so that the inner wall of the lower cover 511 and the covering channel 521 can be continuously attached to the welding slag, which enhances the collection effect of welding slag.

[0047] The cleaning component 57 specifically includes an outer scraper 571 and an inner scraper 572 disposed at the bottom of the rotating disk 55. The outer scraper 571 is attached to the inner wall of the lower cover 511, and the inner scraper 572 is attached to the inner wall of the covering channel 521 near the outer contour. The outer scraper 571 and the inner scraper 572 are connected to the rotating disk 55 by bolts.

[0048] The outer scraper 571 has a reinforcing hook 573 fixed at the end away from the rotating disk 55. The reinforcing hook 573 is in the shape of a "J" and is hooked on the edge of the lower cover 511 away from the upper connector 512. The inner scraper 572 has a reinforcing block 574 fixed at the end away from the rotating disk 55. The reinforcing block 574 is in contact with the inner wall of the covering channel 521 near the inner contour.

[0049] By setting up the cleaning component 57, the outer scraper 571 scrapes off the welding slag adhering to the inner wall of the lower cover 511, and the inner scraper 572 scrapes off the welding slag adhering to the inner wall of the covering channel 521, so that both the lower cover 511 and the covering channel 521 have the ability to continuously adhere to welding slag, further enhancing the collection effect of welding slag. At the same time, the reinforcing hook 573 keeps the outer scraper 571 in close contact with the lower cover 511 for a long time, and the reinforcing block 574 keeps the inner scraper 572 in close contact with the covering channel 521 for a long time, so as to prevent the ends of the outer scraper 571 and the inner scraper 572 away from the rotating disk 55 from loosening after long-term operation and no longer being in close contact with the lower cover 511 or the covering channel 521.

[0050] The power assembly 58 specifically includes a rotating groove 581 opened inside the upper connector 512, a rotating wheel 582 set inside the rotating groove 581, a reinforcing hook 573 set outside the rotating wheel 582, and an inflow channel 584 and an outflow channel 585 opened between the rotating groove 581 and the flow channel 522.

[0051] Specifically, the rotating groove 581 is located at one end of the upper connector 512 near the lower cover 511. The rotating wheel 582 is rotatably connected to the outside of the rotating groove 581. The rotating wheel 582 is fixedly connected to the rotating disk 55. The fan blade 583 is fixedly connected to the rotating wheel 582. The inflow channel 584 and the outflow channel 585 are symmetrically arranged. The inflow channel 584 extends to the outside of the adsorption cover 51. The outer pipe 54 passes through the inflow channel 584 and communicates with the rotating groove 581. The outer pipe 54 is glued to the upper connector 512. The through path of the inflow channel 584 and the outflow channel 585 is tangent to the inner wall contour of the rotating groove 581, so that the airflow can better drive the fan blade 583.

[0052] By setting up the power component 58, when the suction pump is started, the airflow pushes the fan blade 583 and the rotating wheel 582 to rotate, thereby causing the rotating disk 55 to drive the cleaning component 57 to rotate for cleaning. This makes the collection program and the cleaning program work together more perfectly, ensuring the stable operation of the equipment.

[0053] Example 2, refer to Figure 1-6 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that an adjustment component 4 is provided on the outer side of the welding head 3. The adjustment component 4 specifically includes a fixing ring 41 provided on the outer side of the welding head 3, a mounting groove 44 opened on the end of the upper connector 512 away from the lower cover 511, a mounting ring 43 provided on the inner side of the mounting groove 44, and an adjustment spring 42 provided between the mounting ring 43 and the fixing ring 41.

[0054] By setting the adjustment component 4, the adsorption cover 51 is fixed to the mounting ring 43, and the adsorption cover 51 and the adsorption hole 53 are slidably mounted on the outside of the welding head 3. In this way, when there is obstruction around the welding point, the adsorption cover 51 can move a certain distance along the welding head 3 to avoid it, thus making the equipment more adaptable.

[0055] The remaining structure is the same as that in Example 1.

[0056] Based on embodiments 1-2, the working principle of the automatic welding robot of the present invention that avoids welding slag falling onto the workpiece is as follows:

[0057] During installation, the outer scraper 571 and inner scraper 572 are fixed below the rotating disk 55, and the rotating wheel 582 is fixed above the rotating disk 55. Then, the adsorption cover 51 is split into two halves. The adsorption cover 51 is then brought close to the inner side of the adsorption cover 51. The rotating disk 55 is inserted into the adsorption cavity 52 through the through hole, and the rotating wheel 582 also enters the rotating groove 581. Then, the rotating disk 55 is rotated so that the inner scraper 572 enters the covering channel 521 and adheres to the inner wall of the covering channel 521 near the outer contour. The reinforcing block 574 adheres to the inner wall of the covering channel 521 near the inner contour, and the outer scraper 571 adheres to the inner wall of the lower cover 511. The reinforcing hook 573 also overlaps the edge of the lower contour of the lower cover 511. Finally, the other half of the adsorption cover 51 is joined together with this adsorption cover 51, and the fixing sleeve 59 is placed on top of the adsorption cover 51.

[0058] Weld the fixing ring 41 and the mounting ring 43 to both ends of the adjusting spring 42. Then insert the mounting ring 43 into the mounting groove 44. Use bolts to fix the fixing sleeve 59, the adsorption cover 51, and the adsorption hole 53. Then, put the fixing ring 41, the adjusting spring 42, the mounting ring 43, and the adsorption cover 51 on the outside of the welding head 3. Then use bolts to fix the fixing ring 41 on the outside of the welding head 3, so that the adsorption cover 51 covers the outside of the end of the welding head 3.

[0059] In use, the suction pump is started, and the suction pump draws air from the rotating groove 581 through the external pipe 54. The air in the flow channel 522 flows into the rotating groove 581 through the outflow channel 585 to replenish it. In this way, the air flows in the rotating groove 581, and the air blows against the outside of the fan blade 583. The fan blade 583 pushes the rotating wheel 582 to rotate. The rotating wheel 582 drives the outer scraper 571 and the inner scraper 572 to rotate through the rotating disk 55. At the same time, the air in the covering channel 521 flows into the flow channel 522 through the connecting hole 56, and the air inside the lower cover 511 enters the covering channel 521 through the suction hole 53. In this way, a stable airflow is formed. During the welding process, welding slag splashes from the weld point to all sides. Under the influence of the airflow, the welding slag flows to the inner wall of the lower cover 511 and the adsorption hole 53. Since the liquid welding slag has a certain degree of adhesion, some welding slag will adhere to the inner wall of the lower cover 511, and the other part of the welding slag that enters the adsorption hole 53 will adhere to the inner wall of the covering channel 521. At the same time, the high-speed airflow will cool these high-temperature welding slags. The rotating outer scraper 571 and inner scraper 572 will remove the welding slags that adhere to the inner wall of the lower cover 511 and the covering channel 521. These detached low-temperature welding slags flow with the airflow along the airflow channel and are finally discharged through the outer pipe 54.

[0060] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
