Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of robots, specifically relating to a device for preventing welding slag spatter used in welding robots. Background Technology
[0002] Welding robots are industrial robots that perform welding. They are industrial robots with welding guns or torches attached to the end-axis flange, enabling them to perform welding. Currently, welding robots are widely used in the automotive manufacturing industry for welding work on car chassis, seat frames, guide rails, mufflers, and hydraulic torque converters, especially in the production of car chassis. During welding, they ensure that weld slag does not splatter onto workers and also shield the welding arc light to prevent slag from flying everywhere.
[0003] Currently, the anti-slag spatter devices used for welding robots generate welding slag at the welding point on the workpiece surface, which then splatters in all directions. The slag falls on the welding robot and welding table, and can easily splash onto workers, which is not only unsafe but also inconvenient to clean up. In addition, welding robots generate welding fumes when welding workpieces, resulting in heavy air pollution at the welding area, and it is not convenient to absorb and filter the welding fumes before releasing them.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0030] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0031] Example 1
[0032] Reference Figure 1-6 This is the first embodiment of the present invention, which provides a device for preventing weld spatter from splashing onto a welding robot, comprising:
[0033] The welding robot 1 includes a robot body 12, a mounting base 11 fixed to the bottom of the robot body 12, and a welding torch 13 fixedly mounted to the top of the robot body 12.
[0034] The welding fume extraction mechanism 2 includes a fan 26 fixedly installed on the top of the welding torch 13, a duct 27 connecting both sides of the fan 26, and a fume filter box 22 connected to one side of the fan 26.
[0035] The anti-splatter mechanism 3 includes a connecting ring 34 that is slidably sleeved on the surface of the welding torch 13, an mounting ring 32 that is fixed on the surface of the welding torch 13 and located above the connecting ring 34, a connecting rod 31 that is uniformly fixed to the top of the connecting ring 34 and slides through the surface of the mounting ring 32, a protective cover 33 that is fixedly connected to the bottom of the connecting ring 34, and a slag receiving mechanism 4 that is fastened to the bottom of the inside of the protective cover 33.
[0036] Among them, a protective cover 33 is elastically and telescopically installed at the bottom end of the welding torch 13 by means of the mounting ring 32 and the connecting ring 34. The protective cover 33 prevents the welding slag generated during welding of the welding torch 13 from splashing, and collects part of the welding slag through the receiving groove 42 at the top of the receiving ring 41, reducing the scattering of welding slag, facilitating the quick cleaning of welding slag in a small area at the welding point, and preventing welding slag from splashing onto the human body surface.
[0037] An exhaust fan 26 is installed at the top of the welding torch 13. The bottom ends of the exhaust pipes 27 on both sides are inserted into the protective cover 33 and close to the bottom of the welding torch 13 to extract the fumes generated by the welding torch 13 and put them into the filter box 22 for filtration and cleaning, thereby reducing the pollution of the surrounding air by the welding fumes and making it more environmentally friendly.
[0038] Specifically, the slag receiving mechanism 4 includes a receiving ring 41 installed at the bottom of the inside of the protective cover 33 and a receiving groove 42 opened at the top of the receiving ring 41.
[0039] The protective cover 33 has a connecting hole 310 at the bottom of its surface. The connecting hole 310 is a threaded hole structure. The outer side of the receiving ring 41 has a uniformly distributed positioning groove 43. The positioning groove 43 and the connecting hole 310 are aligned with each other. The first bolt 35 is rotated inside the connecting hole 310. The inner end of the first bolt 35 abuts against and is inserted into the positioning groove 43. The receiving ring 41 is set horizontally.
[0040] The receiving ring 41 is detachably fastened to the bottom of the inner side of the protective cover 33 by the first bolt 35. When the welding torch 13 welds the workpiece, the protective cover 33 intercepts the welding slag generated by welding, so that some of the welding slag falls into the inside of the receiving groove 42. The receiving groove 42 receives some of the welding slag, reducing the welding slag from scattering at the welding point. Therefore, it is convenient to quickly clean the welding slag in a small area at the welding point.
[0041] Furthermore, the top part of the welding torch 13 is a cylindrical structure, and its bottom part is a conical structure. The mounting ring 32 and the connecting ring 34 are both circular structures and are horizontally set. The surface of the mounting ring 32 is evenly provided with mounting holes 311, and the top of the connecting rod 31 slides through the mounting holes 311.
[0042] The connecting rod 31 is a threaded rod structure and is vertically set. Its top end is connected to the top end of the mounting hole 311 with a limit nut 39. A spring 38 is sleeved on the surface of the connecting rod 31, and the spring 38 is located between the connecting ring 34 and the mounting ring 32.
[0043] The connecting ring 34 is installed at the bottom of the mounting ring 32 via the connecting rod 31. The connecting ring 34 is elastically connected to the mounting ring 32 via the spring 38. When the welding robot 1 moves the welding torch 13 to the welding position and the welding torch 13 approaches the workpiece to weld it, the protective cover 33 elastically abuts against the outside of the workpiece via the connecting ring 34 and the spring 38 to reduce impact and collision. It is also tightly abutted by the first rubber ring 36 to reduce the dispersion of fumes generated during welding. In addition, it is easy to disassemble and replace the protective cover 33 and the spring 38.
[0044] Preferably, the protective cover 33 has a plug hole 37 on its surface, the bottom end of the exhaust pipe 27 passes through the plug hole 37 and is close to the bottom end of the welding torch 13, the exhaust pipe 27 adopts a telescopic flexible hose structure, and a discharge pipe 25 is connected to one side of the exhaust fan 26, and a first flange 23 is fixed to the outer end of the discharge pipe 25.
[0045] One end of the filter box 22 is connected to an air inlet pipe 29. The outer end of the air inlet pipe 29 is fixed with a second flange 24. The second flange 24 is connected to the first flange 23 by a second bolt 28, which is tightened with a nut. The other end of the filter box 22 is connected to an air outlet pipe 21. The filter box 22 contains activated carbon particles, a filter screen, and aromatic hydrocarbon particles, which are used to filter the incoming flue gas.
[0046] The exhaust fan 26 draws air around the bottom of the welding torch 13 through the exhaust pipe 27, extracting the fumes generated by the welding torch 13 and feeding them into the filter box 22. The fumes are filtered by activated carbon particles, filter screens, and aromatic hydrocarbon particles inside the filter box 22, ensuring that clean air is discharged, which is relatively environmentally friendly.
[0047] The protective cover 33 has a conical structure, with a first rubber ring 36 bonded to its bottom end, and a second rubber ring 312 bonded to the inner surface of the connecting ring 34. The second rubber ring 312 is tightly fitted onto the surface of the welding torch 13.
[0048] The connecting ring 34 is connected to the surface of the welding torch 13 via the first rubber ring 36 to reduce the dispersion of welding fumes, while the second rubber ring 312 is attached to the bottom of the protective cover 33 to reduce the impact between the protective cover 33 and the external structure, and can also reduce the dispersion of welding fumes. The fumes are extracted by the exhaust fan 26 to maintain a good air environment at the welding site.
[0049] When in use, after the welding robot 1 is installed by the mounting base 11, it drives the welding gun 13 to move to the workpiece position and perform welding. At the same time, the protective cover 33 approaches and elastically abuts against the welding position. The protective cover 33 elastically abuts against the outside of the workpiece through the connecting ring 34 and the spring 38 to reduce impact and collision. It also tightly abuts against the first rubber ring 36 to reduce the dispersion of fumes generated during welding.
[0050] When the welding torch 13 is welding a workpiece, the protective cover 33 intercepts the welding slag produced by welding, so that some of the welding slag falls into the inside of the receiving groove 42. The receiving groove 42 receives some of the welding slag, reducing the amount of welding slag scattered at the welding point, and making it easier to quickly clean the welding slag in a small area at the welding point.
[0051] The exhaust fan 26 draws air around the bottom of the welding torch 13 through the exhaust pipe 27, extracting the fumes generated by the welding torch 13 and feeding them into the filter box 22. The fumes are filtered by activated carbon particles, filter screens, and aromatic hydrocarbon particles inside the filter box 22, ensuring that clean air is discharged, which is relatively environmentally friendly.
[0052] In summary, the protective cover 33 is elastically and telescopically installed at the bottom of the welding torch 13 by means of the mounting ring 32 and the connecting ring 34. The protective cover 33 prevents the welding slag generated during welding by the welding torch 13 from splashing, and collects part of the welding slag through the receiving groove 42 at the top of the receiving ring 41, reducing the scattering of welding slag, facilitating the quick cleaning of welding slag in a small area at the welding point, and preventing welding slag from splashing onto the human body surface.
[0053] An exhaust fan 26 is installed at the top of the welding torch 13. The bottom ends of the exhaust pipes 27 on both sides are inserted into the protective cover 33 and close to the bottom of the welding torch 13 to extract the fumes generated by the welding torch 13 and put them into the filter box 22 for filtration and cleaning, thereby reducing the pollution of the surrounding air by the welding fumes and making it more environmentally friendly.
