Description

Technical Field

[0001] The invention relates to the technical field of industrial robot welding, and in particular to a welding device for industrial robot processing. Background Art

[0002] In modern manufacturing, welding is a vital process and is widely used in many fields such as automobile manufacturing, aerospace, building structures, and electronic equipment. The traditional manual welding method is not only labor-intensive and inefficient, but also the welding quality often depends on the experience and skills of the welder, and it is difficult to ensure stability and consistency. With the rapid development of science and technology, industrial robot welding technology has emerged. This technology integrates knowledge from multiple disciplines such as mechanical engineering, electrical engineering, computer science, and control theory. Early industrial robot welding systems were mainly based on a simple teaching and reproduction mode. The operator needed to manually guide the robot to complete the teaching of the welding path, and the robot then repeated the operation according to the recorded path. However, this method has poor adaptability to complex welding tasks and variable workpiece shapes. In recent years, with the continuous advancement of sensor technology, such as visual sensors and force sensors, industrial robot welding systems can achieve more accurate weld tracking and adaptive control. Through visual sensors, robots can obtain the position and shape information of the weld in real time, so as to adjust the welding posture and parameters in time to ensure welding quality. At the same time, industrial robot welding technology has also made significant progress in intelligence. By introducing artificial intelligence algorithms and machine learning technology, the robot can autonomously learn and optimize welding process parameters to improve welding efficiency and quality. For example, by analyzing a large amount of welding data using deep learning algorithms, the robot can predict the optimal welding parameters under different material and workpiece conditions.

[0003] In practical applications, industrial robot welding still has some shortcomings. For example, in the process of welding thicker plates, as shown in the attached manual Fig. 9 As shown, it is necessary to grind out a welding groove 51 at the joint of the two welding parts 5, so as to increase the welding area and enable the welding parts of the two welding parts 5 to be fully welded and fused through the solder 6. However, in this process, grooving and welding are two different operation steps, which is more in terms of processing steps, and the surface of the welding groove 51 of the welding part 5 is oxidized when it is exposed to the air for a long time, and there are more impurities during welding, which reduces the degree of fusion between the metal inside the welding groove 51 and the solder.

DETAILED DESCRIPTION

[0029] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0030] The welding device for industrial robot processing according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0031] like Figure 1-Figure 8 As shown, the welding device for industrial robot processing provided by an embodiment of the present invention includes a weld groove processing mechanism 2 and a welding mechanism 1, wherein the weld groove processing mechanism 2 is used to grind a weld groove 51 at the welding point of two adjacent weldments 5, and the weld groove processing mechanism 2 includes a grinding wheel 21 and a cleaning roller 22, wherein a grinding blade 212 is provided at the rim of the grinding wheel 21, and the cleaning roller 22 is provided at the rim of the grinding wheel 21.

[0032] The welding mechanism 1 includes a cover plate 12, a welding rod guide assembly 13 and a fire welding assembly 14, wherein the cover plate 12 is provided with a traveling wheel 11 for driving the same to move, a grinding wheel 21 is provided at one end of the cover plate 12 for movement, the welding rod guide assembly 13 is provided on the cover plate 12 for introducing the welding rod 31, the fire welding assembly 14 is provided at the bottom of the cover plate 12 for melting the welding rod 31 and the metal on the inner wall of the welding groove 51, and the fire welding assembly 14 includes a flame spray head 144 provided at the bottom of the cover plate 12.

[0033] Specifically, when welding the welded parts 5, firstly, the welded parts of the two welded parts 5 are butted tightly, and the two welded parts 5 are fixed, and then the high-speed rotating grinding wheel 21 moves along the butted gap, and the grinding wheel 21 grinds the butted gap into a shape as shown in FIG. Fig. 9 The welding groove 51 shown is convenient for filling with solder 6. As the grinding wheel 21 moves, the cover plate 12 moves together. When the cover plate 12 enters above the welding groove 51, the flame head 144 connects the fuel and oxygen and ignites the mixture. The flame head 144 heats and melts the metal on the inner wall of the welding groove 51. The flame head 144 also heats and melts the welding rod 31 inserted into the cover plate 12 to form solder 6. The solder 6 is fused and welded with the melted metal of the weldment 5. During the movement of the cover plate 12, the cover plate 12 scrapes the solder 6 in the welding groove 51 to make the surface of the welding groove 51 smoother after welding.

[0034] In one embodiment of the present invention, Figure 5 and Figure 7As shown, a magnetic wheel core 213 is provided inside the grinding wheel 21, and two detachable grinding shells 216 are provided outside the grinding wheel 21. The two detachable grinding shells 216 are connected by screws 214. A grinding wheel driving motor 211 for driving the grinding wheel 21 to rotate at high speed is provided on the cover plate 12. The grinding wheel driving motor 211 is connected to the grinding wheel 21 by setting a driving shaft 215.

[0035] Specifically, during the movement of the grinding wheel 21, the grinding wheel driving motor 211 drives the grinding wheel 21 to rotate at a high speed. The built-in magnetic wheel core 213 of the grinding wheel 21 makes the joints of the two welding parts 5 more closely adsorbed, and at the same time, the welding parts 5 and the grinding wheel 21 are also more closely adsorbed, reducing the squeezing and separation of the joints of the welding parts 5 by the two sides of the grinding wheel 21, so that the joints of the welding parts 5 are fully polished. In addition, during the high-speed rotation of the grinding wheel 21, the metal debris that can be magnetically adsorbed will be adsorbed on the surface of the grinding wheel 21, reducing the metal debris falling into the welding groove 51. As the grinding wheel 21 rotates, the metal debris on its surface is horizontally swept out by the rotating cleaning roller 22, reducing the residue on the surface of the grinding wheel 21.

[0036] Since two detachable grinding shells 216 are disposed outside the grinding wheel 21 , welding grooves 51 of different specifications can be ground out by replacing grinding shells 216 of different specifications.

[0037] In one embodiment of the present invention, Figure 2 and Figure 5 As shown, an abrasive material collecting assembly 23 is provided on one side of the cover plate 12 for cleaning the waste chips generated by the grinding wheel 21. The abrasive material collecting assembly 23 includes a collecting trough 236 and a negative pressure fan 231, wherein the collecting trough 236 is arranged at the waste chip discharge end of the grinding wheel 21, a collecting filter cartridge 233 is arranged inside the collecting trough 236, a collecting port 232 is opened at the feeding end of the collecting trough 236, a cleaning roller 22 is rotatably arranged at the collecting port 232, a cleaning brush is arranged on the surface of the cleaning roller 22, and the negative pressure fan 231 is arranged at the exhaust end of the collecting trough 236.

[0038] Specifically, during the rotation of the grinding wheel 21, the metal waste generated by grinding the welding groove 51 is horizontally swept to the collecting port 232 by the rotating cleaning roller 22, and then the metal waste is sucked into the collecting filter cartridge 233 by the action of the negative pressure fan 231, and the air is discharged through the negative pressure fan 231. The filtered metal waste falls to the bottom of the collecting filter cartridge 233 due to gravity.

[0039] In one embodiment of the present invention, Figure 2 and Figure 5As shown, the cleaning roller 22 is rotatably arranged on the inner side of the collecting port 232, two cleaning rollers 22 are arranged, the grinding blade 212 of the grinding wheel 21 is clamped between the two cleaning rollers 22, and a cleaning roller driving motor 221 for driving the cleaning roller 22 to rotate is arranged at the top of the collecting groove 236, and a material guide plate 237 is arranged at the bottom of the collecting port 232.

[0040] Specifically, since the grinding edge 212 of the grinding wheel 21 is clamped between the two cleaning rollers 22, both sides of the grinding wheel 21 can be fully cleaned. Figure 5 As shown in the counterclockwise rotation, the metal scraps centrifugally thrown out by the grinding wheel 21 enter the inclined guide plate 237, and are sucked into the collecting port 232 together with the negative pressure fan 231, thereby reducing the residual metal scraps on the inner wall of the welding groove 51.

[0041] In one embodiment of the present invention, Figure 2 and Figure 5 As shown, the collecting filter cartridge 233 is pluggably arranged inside the collecting tank 236, and a collecting cartridge bottom 234 is arranged at the bottom of the collecting filter cartridge 233 for collecting metal waste, so that the collecting filter cartridge 233 and the metal waste inside can be conveniently removed later, and the collecting filter cartridge 233 is convenient for cleaning; a feed opening 238 is arranged on one side of the collecting filter cartridge 233 corresponding to the collecting port 232, which is used for inhaling the gas mixed with the metal waste, and a hanging buckle 235 is arranged on the top of the collecting filter cartridge 233 for facilitating the removal and installation of the collecting filter cartridge 233.

[0042] In one embodiment of the present invention, Figure 2 and Figure 3 As shown, the welding rod guide assembly 13 is arranged above the welding rod guide rod 122, and the welding rod guide assembly 13 includes a guide box 131, a guide wheel 132 and a driving wheel 133, wherein the guide box 131 is arranged above the welding rod guide rod 122, the guide wheel 132 and the driving wheel 133 are arranged inside the guide box 131, the guide wheel 132 and the driving wheel 133 are used to clamp the welding rod 31 and convey the welding rod 31 downward, and a speed sensor 134 and a controller are arranged at the bottom of the cover plate 12, and the controller is electrically connected to the speed sensor 134 and the driving wheel 133 respectively.

[0043] Specifically, during the welding process, in order to control the feeding speed of the welding rod 31, the moving speed of the cover plate 12 is detected by the speed sensor 134, and the detection data is sent to the controller. The controller controls the rotation speed of the driving wheel 133, and the guide wheel 132 and the driving wheel 133 clamp the welding rod 31 in the middle. The driving wheel 133 rotates to transport the welding rod 31 downward, thereby controlling the conveying speed of the welding rod 31 to ensure that the solder 6 in the welding groove 51 is always filled, so that the welding groove 51 is more neat after welding.

[0044] In one embodiment of the present invention, Figure 2 and Figure 8 As shown, a plurality of slurry holes 121 are provided on the cover plate 12, a welding rod guide rod 122 is provided through the cover plate 12, a gas venting groove 123 is provided on the inner wall of the welding rod guide rod 122, and a welding rod storage box 3 is provided above the welding rod guide assembly 13.

[0045] Specifically, after the welding rod 31 is melted into the solder 6 in the welding groove 51, it fuses with the melted metal on the inner wall of the welding groove 51. The fused solder 6 sinks to the bottom of the welding groove 51 due to gravity. The high-temperature gas generated during welding is discharged upward from the gas venting groove 123 inside the welding rod guide rod 122, preheating the welding rod 31 so that the welding rod 31 melts more quickly and fully when entering the welding groove 51. When there is too much liquid metal, the liquid solder 6 is discharged through the venting hole 121 to prevent the accumulation of solder 6 and damage to the flame nozzle 145.

[0046] In one embodiment of the present invention, Figure 4 and Figure 6 As shown, the flame head 144 is located at the bottom of the moving end of the cover plate 12, and a weld groove scraper 124 is provided at one end of the cover plate 12 corresponding to the flame head 144. The weld groove scraper 124 matches the inner wall of the weld groove 51, and the weld groove scraper 124 is used to clean the inner wall of the weld groove 51 and guide the flame sprayed by the flame head 144.

[0047] Flame nozzles 145 are provided in the horizontal direction and at the bottom of the flame head 144. The flame nozzles 145 in the horizontal direction correspond to the welding rod 31. The air inlet end of the flame head 144 is respectively connected to the fuel tank 141 and the oxygen tank 142 through two air guide pipes 143. An igniter 146 is provided on the flame head 144 for igniting the flame head 144.

[0048] Specifically, the horizontal flame nozzle 145 is used to directly heat and melt the welding rod 31 entering the welding groove 51. The flame nozzle 145 at the bottom of the flame head 144 sprays the flame downward, and the flame flows upward along both sides of the welding groove 51 to heat and melt the entire inner wall of the welding groove 51.

[0049] In one embodiment of the present invention, Figure 2 As shown, a traveling drive motor is arranged inside the traveling wheel 11, a magnetic wheel rim is arranged at the rim of the traveling wheel 11, and a mounting base 4 for connecting a robot arm is arranged on the top of the welding device.

[0050] Specifically, the cover plate 12 is driven forward by the traveling wheel 11, thereby driving the entire device forward. Since a magnetic rim is provided at the rim of the traveling wheel 11, the traveling wheel 11 is tightly attached to a magnetically adsorbable metal surface. At this time, the welding device of the present invention can be attached to the surface of the weldment 5 and walk in an inclined state, thereby enhancing the use environment of welding. The mounting base 4 on the top of the welding device is used to connect a robot arm for more detailed motion control of the device.

[0051] In order to clearly explain the above embodiments, refer to Figure 1-Figure 9 The specific working principle of the welding device for industrial robot processing of the present invention is as follows: when welding the welded part 5, firstly, the mounting base 4 on the welding device is connected to the robot arm, and the movement of the welding device is controlled by the robot arm, and then the welding parts of the two welded parts 5 are closely connected and fixed, and then the grinding wheel driving motor 211 drives the grinding wheel 21 to rotate at high speed. On the one hand, the magnetic wheel core 213 built into the grinding wheel 21 makes the joints of the two welded parts 5 more closely adsorbed, and at the same time, the welded part 5 and the grinding wheel 21 are also more closely adsorbed, reducing the separation of the welded part 5 from the two sides of the grinding wheel 21. In addition, the magnetically adsorbable metal debris generated by the high-speed rotation of the grinding wheel 21 will be adsorbed on its surface, reducing the metal debris falling into the welding groove 51.

[0052] As more metal scraps remain on the surface of the grinding wheel 21, the cleaning roller driving motor 221 drives the cleaning roller 22 to rotate. Since the grinding blade 212 at the edge of the grinding wheel 21 is clamped between the two cleaning rollers 22, the cleaning roller 22 horizontally sweeps out the metal scraps generated by grinding on both sides of the grinding wheel 21. Under the suction of the negative pressure fan 231, the metal scraps are transferred to the collection filter 233 inside the collection port 232. In addition, the metal scraps centrifugally thrown out by the grinding wheel 21 enter the inclined guide plate 237, and are sucked into the collection port 232 together under the action of the negative pressure fan 231, reducing the metal scraps remaining inside the welding groove 51.

[0053] Then the grinding wheel 21 grinds the butt joint gap into a welding groove 51, which is convenient for filling with solder 6. As the grinding wheel 21 moves, the cover plate 12 moves together. When the cover plate 12 enters the top of the welding groove 51, the speed sensor 134 detects the moving speed of the cover plate 12 and sends the detection data to the controller. The controller controls the rotation speed of the driving wheel 133, and then controls the conveying speed of the welding rod 31 to ensure that the solder 6 in the welding groove 51 is always filled, so that the welding of the welding groove 51 is more neat.

[0054] When the welding rod 31 enters the welding groove 51, the flame head 144 connects the fuel tank 141 and the oxygen tank 142 through the gas duct 143, the fuel gas and oxygen are mixed and ignited in the flame head 144, and the flame heats and melts the metal on the inner wall of the welding groove 51, and at the same time melts the welding rod 31 inserted into the cover plate 12 to form solder 6. At this time, the solder 6 is fused and welded with the melted metal of the weldment 5.

[0055] When the cover plate 12 moves, the lower surface scrapes the solder 6 in the welding groove 51, and the welding groove scraper 124 cleans the inner wall of the welding groove 51 to prevent metal waste from mixing in. It also guides the flame sprayed from the flame head 144 so that the flame direction tends to the left, and fully heats and melts the welding rod 31 and the metal on the inner wall of the welding groove 51.

[0056] Subsequently, after the welding rod 31 is melted into the solder 6 in the welding groove 51, it fuses with the melted metal on the inner wall of the welding groove 51. The fused solder 6 sinks to the bottom of the welding groove 51 due to gravity, and the high-temperature gas generated by welding is discharged upward from the gas venting groove 123 inside the welding rod guide rod 122, preheating the welding rod 31 so that it melts more quickly and fully when entering the welding groove 51.

[0057] As the device moves to the right, the solder 6 is continuously cooled and accumulated on the left side, and the cover plate 12 scrapes the top of the solder 6 to make it flush with the surface of the weldment 5, thereby reducing the need for subsequent grinding and finishing.

[0058] In summary, the welding device of the present invention uses a grinding wheel to rotate at high speed to make grooves, and immediately performs fire brazing after obtaining a weld groove of predetermined specifications, thereby reducing the generation of impurities and allowing the welding surface and the solder to fuse more fully. The cover plate is pressed and leveled to make the welding surface more regular, thereby reducing the subsequent repair work.

[0059] The magnetic wheel core built into the grinding wheel of the present invention can make the welding part joint and the grinding wheel more closely adsorbed, reduce separation, and can also adsorb metal debris. The cover plate of the present invention is provided with a magnetic wheel ring at the edge of the traveling wheel, so that the traveling wheel is closely attached to the metal surface that can be magnetically adsorbed, and the welding device can be attached to the surface of the welding part and travel in an inclined state, thereby enhancing the use environment.

[0060] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and deform the above embodiments within the scope of the present invention.
