Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing technology, specifically to an integrated protective device for welding spatter from automobile plugs. Background Technology

[0002] Welding is a crucial process in automobile manufacturing, primarily used to join metal components of the vehicle body. Depending on the specific requirements and material properties, automotive welding employs various types of equipment and techniques, such as resistance spot welding, gas-shielded metal arc welding (MIG welding), and laser welding. To improve welding efficiency and consistency, modern automotive production lines typically utilize robots (robotic arms) to perform these welding operations. Through programming, robots can complete complex welding paths, ensuring consistent quality at each weld point.

[0003] However, welding spatter (also known as weld slag or spatter particles) generated during the welding process can not only affect weld quality but also damage surrounding components. This is especially true for automotive covers (such as doors, hoods, trunk lids, and other body panels), which are highly susceptible to spatter during welding due to their large surface area. When spatter lands on the surface of an automotive cover and solidifies after cooling, it can cause damage or contamination, affecting the final product's appearance and market value. Therefore, effectively preventing welding spatter from damaging automotive covers is a problem that needs to be addressed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an integrated protective device for welding spatter from automotive plugs, thereby improving the protective effect during the welding process of automotive plugs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an integrated protective device for welding spatter from automotive plugs, comprising a base and a robotic arm mounted on the base. A protective component is connected to one end of the robotic arm away from the base, and a suction tube is connected to the protective component. The suction tube extends along the outer side of the robotic arm to the base and is connected to a filter component.

[0006] Furthermore, there are two suction tubes, located on both sides of the robotic arm.

[0007] Furthermore, the protective assembly includes a protective cover and two telescopic components. The two telescopic components are fixedly connected to both sides of the end of the robotic arm away from the base. The protective cover is located below the welded end of the robotic arm. The telescopic ends of the two telescopic components are fixedly connected to both ends of the protective cover on the side closer to the robotic arm. One end of the suction tube is connected to the protective cover.

[0008] Furthermore, the protective cover is funnel-shaped, with the smaller opening of the protective cover away from the robotic arm and the larger opening of the protective cover close to the robotic arm. The end of the protective cover close to the robotic arm is fixedly connected to and connected to several guide tubes, and the other end of the several guide tubes is fixedly connected to and connected to a bend tube. The end of the suction tube is fixedly connected to and connected to the bend tube.

[0009] Furthermore, the filtration assembly includes a filter box and a fan. The filter box is fixedly connected to the base. The end of the suction pipe away from the robotic arm is fixedly connected to and communicates with the filter box. The side of the filter box away from the suction pipe is fixedly connected to and communicates with the fan. A filter screen is connected to the inner wall of the filter box. The filter screen is located between the suction pipe and the fan. A door is connected to one side of the filter box.

[0010] Furthermore, bolts are connected to the four corners of the door, and the threaded rods of the four bolts pass through the four corners of the door and are respectively threaded to the four corners of the filter box.

[0011] Furthermore, several mounting rails are fixedly connected to the inner walls of the upper and lower sides of the filter box, and multiple filter screens are provided, with the screen frames of the multiple filter screens respectively installed in the filter box through several mounting rails.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This integrated protective device for welding spatter from automotive plugs uses a suction tube to draw welding spatter from the inner enclosure of the protective component into the filter component, thereby reducing the high-temperature damage to the surface of the welded workpiece caused by the welding spatter falling onto it and improving the stability of the welding operation.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figures 1 to 5 The integrated protective device for welding spatter from automotive plugs includes a base 1 and a robotic arm 2 mounted on the base 1. A protective component 3 is connected to one end of the robotic arm 2 away from the base 1. The protective component 3 is connected to a suction pipe 4. The suction pipe 4 extends along the outside of the robotic arm 2 to the base 1 and is connected to a filter component 5.

[0022] like Figures 1 to 5 As shown, the main improvement of this utility model lies in reducing the damage to the surface of the welded workpiece caused by welding spatter, such as... Figures 1 to 5 As shown, the integrated protective device for welding spatter from automotive plugs in this utility model, when the robotic arm 2 performs laser welding on the workpiece, the protective component 3 surrounds the welding position of the workpiece, blocking the sparks and other debris from the welding point within the protective component 3. Simultaneously, the protective component 3 moves with the welding end of the robotic arm 2, always maintaining protection of the welding position. The welding spatter within the protective component 3 is then drawn into the filter component 5 through the suction tube 4. The filter component 5 filters the solid particles, ensuring they remain inside, facilitating the collection and treatment of welding waste. It should be noted that the suction tube 4 uses a universal tube or flexible hose, and the inner side of the suction tube 4 must be made of a high-temperature resistant, scratch-resistant material, such as aluminum foil, to prevent the suction tube 4 from being burned by the welding spatter. The suction tube 4 can also be fixed to the robotic arm 2 using cable ties, clamps, etc., so that the suction tube 4 remains on the robotic arm 2 during welding operations.

[0023] like Figure 1 and Figure 3 As shown, there are two suction tubes 4, located on both sides of the robotic arm 2. The two suction tubes 4 can improve the suction effect of splashed particles inside the protective component 3.

[0024] like Figures 1 to 3As shown, the protective assembly 3 includes a protective cover 31 and two telescopic members 32. The two telescopic members 32 are fixedly connected to both sides of the end of the robotic arm 2 away from the base 1. The protective cover 31 is located below the welding end of the robotic arm 2. The telescopic ends of the two telescopic members 32 are fixedly connected to the two ends of the protective cover 31 near the robotic arm 2. One end of the suction pipe 4 is connected to the protective cover 31. The height of the protective cover 31 below the welding end of the robotic arm 2 can be controlled by the two telescopic members 32, which can adapt to different welding requirements. At the same time, the spatter from the welding point flies and diffuses from one end of the protective cover 31 to the inside of the protective cover 31, and the strong suction force provided by the suction pipe 4 can draw the spatter scattered inside the protective cover 31 away from the protective cover 31.

[0025] like Figures 1 to 5 As shown, the protective cover 31 is funnel-shaped, with the smaller opening of the protective cover 31 away from the robotic arm 2 and the larger opening close to the robotic arm 2. Several guide tubes 33 are fixedly connected and connected to the end of the protective cover 31 closest to the robotic arm 2, and the other ends of the guide tubes 33 are fixedly connected and connected to a bent tube 34. The end of the suction tube 4 is fixedly connected and connected to the bent tube 34. The funnel-shaped protective cover 31 can minimize the possibility of spatter splashing to the outside of the protective cover 31. It should be particularly noted that the opening at the smaller end of the protective cover 31 needs to be larger than the welding range of the laser welding on the robotic arm 2 to ensure that the bottom of the protective cover 31 does not contact the workpiece being welded, thus collecting spatter while preventing the protective cover 31 from contacting the molten part of the welding position.

[0026] like Figures 1 to 5 As shown, the filter assembly 5 includes a filter box 51 and a fan 52. The filter box 51 is fixedly connected to the base 1. The end of the suction pipe 4 away from the robotic arm 2 is fixedly connected to and communicates with the filter box 51. The side of the filter box 51 away from the suction pipe 4 is fixedly connected to and communicates with the fan 52. A filter screen 53 is connected to the inner wall of the filter box 51. The filter screen 53 is located between the suction pipe 4 and the fan 52. A door 6 is connected to one side of the filter box 51. The fan 52 provides strong suction force and draws the splashes in the protective cover 31 into the filter box 51 through the suction pipe 4. The internally installed filter screen 53 keeps the drawn-in splashes in the filter box 51, preventing particles from entering the fan 52 and damaging it.

[0027] like Figure 1 and Figure 4As shown, bolts 61 are connected to each of the four corners of the door 6. The threaded rods of the four bolts 61 pass through the four corners of the door 6 and are threadedly connected to the four corners of the filter box 51. The bolts 61 make the installation between the door 6 and the filter box 51 more secure and prevent leakage caused by the strong suction generated by the fan 52 at the installation position between the filter box 51 and the door 6. At the same time, a sealing gasket can be placed between the door 6 and the filter box 51 to further improve the sealing effect.

[0028] like Figure 4 and Figure 5 As shown, several mounting rails 7 are fixedly connected to the inner walls of both the upper and lower sides of the filter box 51. Multiple filter screens 53 are provided, and the frames of the multiple filter screens 53 are respectively installed inside the filter box 51 via the mounting rails 7. The mounting rails 7 allow for quick installation or removal of the filter screens 53 within the filter box 51.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
