Description

Technical Field

[0001] The invention relates to the technical field of welding manipulators, in particular to an automatic manipulator for welding processing with a positioning and guiding function. Background Art

[0002] Welding is an important process in modern industrial manufacturing and is widely used in high-precision fields such as automobile manufacturing, aerospace, and machinery manufacturing. With the rapid development of industrial automation technology, automated manipulators have been widely used in welding. Welding automated manipulators can use positioning and guidance components (such as cameras and laser rangefinders) to perform precise path planning and point recognition, thereby achieving high-precision welding of complex workpieces. This positioning and guidance function is particularly important in complex welding scenarios and is the core foundation for automated manipulators to achieve efficient welding.

[0003] However, although the existing technology focuses on the application of positioning and guiding functions, there are generally deficiencies in the protection of precision components such as cameras and laser rangefinders during welding. Since high-temperature welding beams, slag splashes, and strong arc light are generated during welding operations, these precision components are directly exposed to the welding environment and are easily affected by high temperatures, slag adhesion, and beam interference, resulting in component performance degradation or even damage. In this case, the positioning and guiding function of the welding manipulator will be severely weakened, directly affecting the accuracy of the welding path and the overall welding quality.

[0004] At the same time, a large amount of welding slag generated during the welding process tends to adhere to the surface of the welding head and its surrounding components. Existing welding devices usually rely on manual cleaning of welding slag after welding, which is not only time-consuming and labor-intensive, but also difficult to completely remove the attachments, affecting the continued use performance of the equipment. Although some devices have tried to introduce automated cleaning structures, due to imperfect designs and low cleaning efficiency, the performance of the equipment has been significantly degraded in high-frequency operations, and maintenance costs have increased.

[0005] In addition, during the welding process, the welding head, as a core component that directly acts on the workpiece, will inevitably generate impact force when in contact with the workpiece surface. Due to the lack of effective buffer design in the existing technology, the welding head is prone to displacement or vibration when impacted by external force. This phenomenon not only affects the stability of the welding path, but may also lead to a decrease in welding quality. In high-precision welding scenarios, the amplification of this impact effect is more obvious, becoming a key factor affecting welding accuracy and consistency. Summary of the invention

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Please refer to the attached Figure 1 -Attached Figure 4 The embodiment of the present invention provides an automated robot for welding processing with a positioning and guiding function, comprising a base 1, a robot arm is arranged on the top of the base 1, an L-shaped bracket 5 is installed at the end of the robot arm, a mounting seat 6 is installed on the outer wall of the L-shaped bracket 5, a buffer component is arranged in the middle of the mounting seat 6, which is used to provide a movable space for the welding head 18 during welding, a welding component is arranged in the middle of the buffer component, a protection component is installed at the bottom of the mounting seat 6, which is used to protect the positioning and guiding component from being damaged by the welding beam during welding, and a welding smoke treatment component is installed on the outer wall of the protection component, which is used to timely treat the smoke generated during welding. For processing and discharge, a plurality of movable rods 11 are arranged inside the protective assembly, one end of the plurality of movable rods 11 is rotatably provided with an annular seat 12, the inside of the annular seat 12 is sleeved on the outside of the welding assembly, a moving rod 13 is slidably arranged in the middle of the annular seat 12, a cleaning brush 14 is installed at one end of the annular seat 12, an anti-slip plate 16 is installed at the other end of the annular seat 12, one end of a spring 15 is installed on the outer wall of the anti-slip plate 16, the other end of the spring 15 is installed on the outer wall of the annular seat 12, the inside of the spring 15 is sleeved on the outside of the moving rod 13, a plurality of cleaning brushes 14 are surrounded and fitted on the outer wall of the welding assembly, so as to remove the welding slag on the welding assembly when welding is completed.

[0032] The other end of the movable rod 11 is rotated on the inner wall of the movable frame 9 .

[0033] Specifically, the base 1 provides stable support for the robot arm, and the L-shaped bracket 5 installed at the end of the robot arm serves as a connecting platform for installing various components of the welding device. The mounting seat 6 is fixed on the outer wall of the L-shaped bracket 5 to provide stable structural support for the welding device.

[0034] During the welding process, the buffer assembly is located in the middle of the mounting seat 6 to provide a movable space for the welding head 18. When the welding head 18 contacts the object to be welded, the buffer assembly absorbs the impact force through the compression and rebound of the spring, ensuring the stability of the welding head 18 and improving the welding quality. At the same time, the welding assembly in the buffer assembly realizes the transmission and utilization of welding gas, and the welding gas is stably delivered to the welding head 18 through the welding assembly, maintaining the stability of the welding arc and supporting the melting of the metal.

[0035] The protection component is installed at the bottom of the mounting base 6, and drives the movable frame 9 to expand or retract through multiple electric telescopic rods 8, driving the transparent soft cover 10 to form a protection space. During welding, the protection component prevents the welding beam from damaging the positioning guide components such as the laser rangefinder 26 and the camera 28, and isolates the welding spatter and high temperature to ensure the safety of the equipment and the environment.

[0036] The welding smoke treatment component is fixed to the outer wall of the protection component, and is used to collect and treat the smoke generated during welding. The welding smoke is collected into the five-way pipe 30 through multiple connectors 32 and hoses 31, and enters the processor 34 through the suction of the vacuum pump 29. The filter plate 36 in the processor 34 purifies the smoke, removes harmful substances, and discharges the clean gas through the exhaust pipe 35 to keep the working environment clean.

[0037] The annular seat 12 is connected to the inner wall of the movable frame 9 through a plurality of movable rods 11, and its interior is sleeved on the outside of the welding assembly, and can slide and drive the cleaning brush 14 to move along the outer wall of the welding assembly after welding is completed. The movement of the annular seat 12 is provided with a rebound force by a spring 15, ensuring that the cleaning brush 14 is always in close contact with the outer wall of the welding assembly, so as to effectively remove the welding slag on the outer wall of the welding head 18 and the straight pipe 17 at the end of welding, and avoid the influence of the residue on the performance of the equipment.

[0038] Through the coordinated operation of the above components, the device of the present invention realizes stable and efficient welding operations, and at the same time has protection, cleaning and environmental protection functions.

[0039] Please refer to the attached Figure 1 The robot arm includes a movable arm 2, the bottom of the movable arm 2 is arranged on the top of the base 1, the top of the movable arm 2 is provided with one end of a movable arm 2 3, and the other end of the movable arm 2 3 is provided with a control head 4.

[0040] The top of the L-shaped bracket 5 is installed on the driving end of the control head 4 .

[0041] Specifically, during the working process, the robot arm realizes flexible adjustment of the entire welding device through the linkage of the movable arm 1 2 and the movable arm 2 3. The bottom of the movable arm 1 2 is fixed to the top of the base 1 to provide stable support, and is connected to one end of the movable arm 2 3 through its top, allowing the movable arm 2 3 to realize flexible rotation and displacement in different directions. The other end of the movable arm 2 3 is connected to the control head 4. The control head 4, as the end actuator, can control its direction and position through the central numerical control system, thereby accurately guiding the welding head 18 to complete the welding operation.

[0042] The L-shaped bracket 5 is installed at the driving end of the control head 4, and cooperates with the control head 4 to complete the fine adjustment of the equipment position during the welding process, ensuring the accuracy of the welding path and the efficiency of the welding operation. The control head 4 drives the L-shaped bracket 5 to flexibly adjust the angle and position of the welding device, providing support for precise operation during the welding process.

[0043] Please refer to the attached Figure 5 -Attached Figure 6 The buffer assembly includes a limit cylinder 21, the bottom of which is installed on the top of the mounting seat 6, and a plurality of limit grooves 22 are penetrated in the middle of the limit cylinder 21. A limit rod 23 is installed on the inner wall of each limit groove 22, and a spring 24 is sleeved on the outer side of the limit rod 23. A movable block 25 is slidably arranged on the outer wall of the limit rod 23, and one end of the spring 24 is installed on the outer wall of the limit groove 22, and the other end of the spring 24 is installed on the top of the movable block 25.

[0044] Specifically, during the welding process, since the welding head 18 is a hard shell, when the welding head 18 contacts the outer wall of the object to be welded, in order to reduce the impact force and improve the welding quality, the welding head 18 will move back a distance inside the adjustment tube 19. This moving back action will drive the movable block 25 to slide upward along the outer wall of the limit rod 23, thereby squeezing the spring 24 sleeved on the outside of the limit rod 23, so that the spring 24 is compressed.

[0045] The compression of the spring 24 will generate a rebound reaction force, which is transmitted back through the movable block 25, pushing the movable block 25 to move back. This buffering process effectively absorbs the impact force when the welding head 18 contacts the surface of the object to be welded, reducing the welding quality problems caused by contact impact. At the same time, the limiting cylinder 21 and the limiting groove 22 inside it provide a limited path for the movement of the movable block 25, ensuring that the sliding process of the movable block 25 is smooth and accurate, thereby achieving effective shock absorption and stabilization of the buffer assembly.

[0046] Please refer to the attached Figure 1 and attached Figure 7 The welding assembly includes a gas pipe 20, the outer wall of the gas pipe 20 is installed on the outer wall of the movable arm 23, one end of the gas pipe 20 is connected to the gas delivery equipment, the other end of the gas pipe 20 is installed with one end of the regulating pipe 19, the other end of the regulating pipe 19 is installed with one end of the straight pipe 17, the other end of the straight pipe 17 is installed with a welding head 18, and the outside of the straight pipe 17 is arranged in the mounting seat 6.

[0047] The outer wall of the movable block 25 is installed on the outer wall of the adjusting pipe 19.

[0048] Specifically, during the welding process, the welding gas is transported from the gas delivery device to the welding head 18 through the gas delivery pipe 20. One end of the gas delivery pipe 20 is connected to the gas delivery device, and the other end is connected to the regulating pipe 19. The welding gas enters the straight pipe 17 through the regulating pipe 19 and is finally transported to the welding head 18. The welding gas is directly used in the welding process at the welding head 18, for example, as a welding gas to maintain the stability of the welding arc or promote the melting of the metal.

[0049] The straight tube 17 is externally arranged in the mounting seat 6, and the mounting seat 6 provides a stable support for the straight tube 17, while limiting its excessive displacement or vibration during the welding process. The mounting seat 6 serves as a fixed structure to ensure the stability of the welding assembly during the welding operation, thereby improving the accuracy of welding.

[0050] One end of the regulating tube 19 is connected to the gas pipe 20, and the other end is connected to the straight tube 17, which not only ensures the smooth transmission of the welding gas, but also provides flexibility, so that the welding head 18 can produce a certain amount of back movement according to the contact situation during the welding process to absorb the impact of external forces. The movable block 25 is installed on the outer wall of the regulating tube 19, and can cooperate with the limit rod 23 and the spring 24 to complete the buffering action when the straight tube 17 contacts the outer wall of the object to be welded. When the welding head 18 contacts the outer wall of the object to be welded and generates an impact force, the spring 24 is compressed and rebounds, and the movable block 25 slides on the limit rod 23, thereby absorbing the impact force, reducing the impact on the welding head 18, and improving the welding quality.

[0051] The straight pipe 17 is protected and fixed by the mounting base 6 to ensure the stable operation of each component during the welding process and avoid the degradation of welding quality due to vibration or external force. The welding gas is stably delivered to the welding head 18 through the straight pipe 17 to complete the welding operation.

[0052] Please refer to the attached Figure 2 -Attached Figure 3 The protection component includes a mounting plate 7, the top of the mounting plate 7 is mounted on the bottom of the mounting seat 6, and multiple grooves on the outer wall of the mounting plate 7 are used to rotate multiple electric telescopic rods 8. The driving end of each electric telescopic rod 8 is installed with a movable skeleton 9 through a rotating shaft, and transparent soft covers 10 are installed on the outer walls of the multiple movable skeletons 9. The top of the transparent soft cover 10 is installed at the bottom of the mounting seat 6.

[0053] Specifically, before the welding work begins, the protection component is first started, and the multiple electric telescopic rods 8 are started in turn, and the driving end thereof drives the movable frame 9 installed thereon to unfold through the rotating shaft. When the movable frame 9 gradually opens, the transparent soft cover 10 fixed on its outer wall unfolds accordingly, thereby forming a semi-enclosed protective space in the welding area. The transparent soft cover 10 is made of a high-temperature resistant transparent silicone film, which can effectively isolate the welding sparks, slag and high-temperature heat generated during the welding process, while maintaining good perspective to monitor the welding process.

[0054] The top of the transparent soft cover 10 is fixed to the bottom of the mounting base 6 , so when the transparent soft cover 10 is opened, it can completely cover the welding head 18 and the welding area, providing all-round protection.

[0055] During the welding process, the transparent soft cover 10 not only provides physical protection, but also effectively isolates the spatter and high temperature generated by welding, preventing them from damaging the welding equipment and the surrounding environment. In addition, the transparent soft cover 10 will not affect the measurement accuracy of the laser rangefinder 26, and can ensure the normal measurement of the welding point.

[0056] When welding is finished, the electric telescopic rod 8 is started again, and its driving end drives the movable frame 9 to be retracted through the rotating shaft, and at the same time, the transparent soft cover 10 is also folded and retracted as the movable frame 9 is retracted.

[0057] Please refer to the attached Figure 3 The positioning and guiding assembly includes a laser rangefinder 26, the top of which is mounted on the outer wall of the L-shaped bracket 5, one end of a bracket 27 is mounted on the outer wall of the mounting seat 6, and a camera 28 is mounted on the other end of the bracket 27. The laser rangefinder 26 and the head of the welding head 18 are respectively located on two vertical parallel lines.

[0058] Specifically, the top of the laser rangefinder 26 is mounted on the outer wall of the L-shaped bracket 5, and is located on the vertical parallel line of the head of the welding head 18. When the welding operation starts, the laser rangefinder 26 emits laser light to the welding area of ​​the object to be welded, and accurately measures the distance between the welding point and the welding head 18 through the time or intensity information of the laser reflection back. The measurement data is transmitted to the central numerical control system in real time, which is used to calculate the welding path and adjust the running track of the welding head 18, so as to ensure that the welding head 18 always remains in the best welding position.

[0059] One end of the bracket 27 is mounted on the outer wall of the mounting seat 6, and the other end is mounted with a camera 28. The camera 28 can be stably aligned with the welding area by the fixing of the bracket 27. Before welding begins, the camera 28 collects image information of the welding area, including the location of the welding point, the surface characteristics of the object, and the surrounding environment. These image information are transmitted to the central numerical control system, combined with the distance measurement data provided by the laser rangefinder 26, and a comprehensive analysis is performed on the welding area to calculate the optimal welding path.

[0060] The laser rangefinder 26 and the head of the welding head 18 are located on two vertical parallel lines. This layout design ensures that the laser rangefinder 26 can operate independently of the welding head 18, is not affected by the high temperature and sparks of the welding head 18, and accurately measures the depth or distance of the welding point. The camera 28 collects image information of the welding point from different perspectives, which complements the data of the laser rangefinder 26 to ensure the accuracy of path planning.

[0061] During the welding process, if the surface of the object is uneven or the welding point deviates, the laser rangefinder 26 and the camera 28 can monitor the dynamic changes of the welding area in real time and transmit the new data to the central numerical control system. The central numerical control system adjusts the movement of the movable arm 1 2, the movable arm 2 3 and the control head 4 according to the latest measurement results to ensure that the welding head 18 always runs along the planned path, thereby achieving efficient and accurate welding.

[0062] Please refer to the attached Figure 5 and attached Figure 8 The welding smoke processing component includes a plurality of connectors 32, which are respectively installed in the middle of a plurality of movable skeletons 9, one end of each connector 32 is installed with one end of a hose 31, an exhaust pump 29 is installed on the outer wall of the L-shaped bracket 5, a five-way pipe 30 is installed on the input end of the exhaust pump 29, the other end of each hose 31 is installed on the connecting end of the five-way pipe 30, the output end of the exhaust pump 29 is connected to one end of a connecting pipe 33, a processor 34 is installed on the other end of the connecting pipe 33, the outer wall of the processor 34 is installed on the outer wall of the L-shaped bracket 5, a filter plate 36 is installed on the inner wall of the processor 34, and an exhaust pipe 35 is installed on the top of the processor 34.

[0063] Specifically, during the welding process, a large amount of welding smoke and harmful particles will be generated around the welding head 18. During the welding process, the welding smoke processing component collects the welding smoke generated by welding through the connector 32 in the middle of the movable frame 9. The welding smoke is collected into the five-way pipe 30 through the hose 31, and then sucked into the connecting pipe 33 by the vacuum pump 29 and transmitted to the processor 34. The filter plate 36 in the processor 34 filters the welding smoke, removes harmful substances, and discharges the purified gas through the exhaust pipe 35, thereby realizing efficient collection and environmentally friendly discharge of welding smoke. The entire system is synchronized with the welding operation, dynamically adjusts the collection range, and ensures the cleanliness and safety of the welding environment.

[0064] Working principle: When using the device of the present invention to perform welding processing, it is necessary to first start the mechanical arm of the manipulator of the present invention, and under the flexible control of the movable arm 1 2, the movable arm 2 3 and the control head 4, enable the camera 28 to record image information of the welding point of the object to be welded in advance, and analyze the recorded image information through the central numerical control system to obtain the path information of the welding point of the object to be welded, and then under the control of the central numerical control system, under the flexible control of the movable arm 1 2, the movable arm 2 3 and the control head 4, enable the welding head 18 to weld the object to be welded on the path obtained by analysis, and at the same time, during welding, the buffer component, the protection component, and the welding smoke treatment component are all started and operated synchronously.

[0065] The protection component is pre-activated and opened before welding, and multiple electric telescopic rods 8 are activated to control the movable frame 9 to open the transparent soft cover 10. During the welding process, the laser rangefinder 26 is protected from being damaged by the welding beam when measuring the welding point.

[0066] During welding, since the welding head 18 is a hard shell, in order to improve the welding quality of the object to be welded, when the welding head 18 contacts the outer wall of the object to be welded, the welding head 18 will move back a part inside the adjusting tube 19, driving the movable block 25 to move up along the outer wall of the limiting rod 23, thereby squeezing the spring 24, causing it to compress and produce a rebound reaction force, thereby pushing the movable block 25 to move back, so that when the camera 28 contacts the surface of the object to be welded, the impact force is reduced, and the welding quality is improved.

[0067] At the same time, the welding smoke generated during the welding process will be collected into the five-way pipe 30 through the connecting head 32 and the hose 31 under the suction force of the vacuum pump 29, and will continue to enter the processor 34 through the connecting pipe 33 under the continuous extraction of the vacuum pump 29, and will be filtered by the laser rangefinder 26 and discharged from the exhaust pipe 35.

[0068] After welding is completed, multiple electric telescopic rods 8 are started, driving the movable frame 9 to retract, so that the welding head 18 is folded and retracted. At this time, when the movable frame 9 is retracted, it will drive the movable rod 11 connected to the inner wall to move, and then push the annular seat 12 to move down. At this time, the annular seat 12 drives the movable rod 13 to move down synchronously, and multiple cleaning brushes 14 move along the straight tube 17 and the outer wall of the welding head 18. Affected by the outer wall of the straight tube 17 and the welding head 18, it will produce a certain movement, pushing the anti-slip plate 16 to move. At this time, the spring 15 is subjected to the reaction force of rebound, thereby ensuring that the movable rod 13 always pushes the cleaning brush 14 to be close to the outer wall of the straight tube 17 and the welding head 18, so that when the annular seat 12 moves down, its cleaning brush 14 will move down along the outer wall of the straight tube 17 and the welding head 18. When the cleaning brush 14 moves to the end of the welding head 18, the welding slag sticking to the outer wall of the straight tube 17 and the welding head 18 will be cleaned and dropped.
