Description

Technical Field

[0001] This utility model relates to the field of automated welding technology, and in particular, to a protective device for automated welding. Furthermore, this utility model also relates to an automated welding apparatus including the aforementioned protective device for automated welding. Background Technology

[0002] Common welding masks include handheld and head-mounted masks. Handheld masks are simple in structure, mainly consisting of a mask, filter lenses, and a handle, but their handheld design makes them inconvenient to use. Head-mounted masks improve the ease of operation for workers, but with the trend towards welding automation, combining welding masks with automatic welding equipment makes it difficult for workers to observe and operate the equipment, reducing work efficiency and making them unsuitable for automated welding. When using automatic welding equipment, workers need to observe details such as welding torch oscillation and welding path deviation from multiple directions and at close range while operating the equipment to ensure welding quality.

[0003] For example, utility model patent CN215900075U discloses a welding arc light protection device for intelligent manufacturing. This device includes a protective face shield, a purification mechanism, and a fixing component. The outer wall of the face shield has openings into which a protective lens is fixedly installed. The purification mechanism includes an air pump, a ring pipe, an activated carbon box, a flexible hose, and an air inlet. The fixing component includes a gripping mechanism and a fixing mechanism, with the gripping mechanism located below the fixing mechanism. This welding arc light protection device for intelligent manufacturing, through the coordinated use of these mechanisms, collects harmful gases generated during welding, reduces the harmfulness of the gases through circulation purification, and discharges the gases through pipes. Combined with a grip, it prevents safety accidents during welding, improves welding safety, is easy to carry, and is highly practical. This technical solution adds a purification mechanism and a fixing strap to a handheld face shield, thereby solving the problems of toxic gas hazards generated during welding and the need for prolonged handholding by workers. However, with the trend of welding automation, the combination of welding masks and automatic welding equipment is not convenient for operators to observe and operate the equipment, reducing work efficiency and is not suitable for automated welding.

[0004] For example, the welding protection device and welding equipment disclosed in utility model patent CN218016330U include: a welding head configured to weld the workpiece; a monitoring camera configured to monitor the welding of the workpiece inside the cylindrical body; a display screen connected to the monitoring camera; and a welding protection device, which includes a cylindrical body and a viewing plate; the cylindrical body can cover the workpiece, and has a channel and an observation slot; the welding head passes through the channel into the cylindrical body; the observation slot can observe the workpiece inside the cylindrical body; and the viewing plate covers the observation slot. The welding protection device and welding equipment of this application have the advantage of convenient observation. This utility model patent addresses the problem of the welding process being unable to be directly observed due to the closed structure of the welding protection device by installing a monitoring camera inside the protection device and a viewing glass plate on the protective cylinder, facilitating observation of the welding process. While this solves the problem of observing whether the welding is normal, in automated welding processes, it is still necessary to observe details such as welding torch oscillation and welding path deviation from multiple directions and at close range to ensure welding quality.

[0006] According to one aspect of the present invention, a protective device for automated welding is provided, comprising:

[0007] The protective cover is square in shape and open at the bottom. It is used to be set on a work platform or on a workpiece and cover the welding area of ​​the workpiece. The top of the protective cover is provided with a mounting structure for cooperating with the welding gun of an automated welding equipment.

[0008] A dust removal device is connected to and communicates with the protective cover, and is used to suck up the smoke and dust inside the protective cover;

[0009] An observation device, disposed within the protective cover, is used to filter arc light and to observe the welding area of ​​the workpiece. The observation device includes an observation tube passing through the protective cover, the observation tube having a bent structure arranged within the protective cover. The observation device also includes a periscope assembly for projecting an image from the first end of the observation device onto the second end of the observation device.

[0020] When this protective device is used in automated welding, the entire protective cover is installed on the work platform or workpiece, completely covering the welding area. The welding torch is adjusted to the appropriate position for the weld bead by the automated welding equipment. During the adjustment process, the position of the welding torch is observed through an observation tube. The observation tube is adjusted by rotating the structure to adjust the observation direction and confirm that the welding torch is in the correct position. During welding, the protective cover isolates spatter and welding gases. The welding area is observed through the observation tube, which also filters the arc light. The observation tube is obliquely arranged, and by incorporating a bent tube and a periscope assembly, the welding area outside the first end of the observation tube is imaged onto the second end of the observation tube.

This allows for multi-directional, equivalent close-range observation of details such as welding torch oscillation and welding path deviation, ensuring welding quality while improving working conditions and efficiency. Furthermore, during welding, a dust removal device continuously extracts fumes from the protective cover, expelling gases from within the welding cover. This facilitates observation while mitigating the risk of toxic gas hazards during welding, preventing accidents and enhancing welding safety.

[0030] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0031] Figure 1 This is a reference diagram showing the usage state of a preferred embodiment of this utility model; Figure 2 This is a front cross-sectional view of the protective device in use according to a preferred embodiment of the present invention; Figure 3 This is a side cross-sectional view of the protective device in use according to a preferred embodiment of the present invention; Figure 4 This is a schematic diagram of the internal structure of the observation tube according to a preferred embodiment of the present invention; Figure 5 This is a schematic diagram of the rotating structure of another embodiment of the present invention.

[0032] like Figures 1 to 4 As shown, the protective device for automated welding in this embodiment includes:

[0033] The protective cover 100 is square and open at the bottom. It is used to be set on the work platform or on the workpiece 400 and cover the welding area of ​​the workpiece 400. The top of the protective cover 100 is provided with a mounting structure for cooperating with the welding gun 500 of the automated welding equipment.

[0034] A dust removal device 300 is connected to and communicates with the protective cover 100 and is used to suck up the smoke and dust inside the protective cover 100.

[0035] An observation device is installed in the protective cover 100 to filter arc light and to observe the welding area of ​​the workpiece 400. The observation device includes an observation tube 200 that passes through the protective cover 100. The observation tube 200 has a bent structure arranged inside the protective cover 100. The observation device also includes a periscope assembly 202 for projecting an image from the first end of the observation device to the second end of the observation device. A rotating structure 205 is provided on the observation tube 200 for adjusting the position and / or orientation of the first end of the observation tube 200.

[0036] Understandably, when this protective device is applied to automated welding, the protective cover 100 is installed entirely on the work platform or workpiece 400, covering the entire welding area. The welding torch 500 is adjusted to a suitable position by the automated welding equipment. During the adjustment process, the position of the welding torch 500 is observed through the observation tube 200. The observation tube 200 is adjusted by the rotating structure 205 to adjust the observation direction, confirming that the welding torch 500 is in the appropriate position. During welding, the protective cover 100 isolates spatter and welding gases. The welding area is observed through the observation tube 200, which also filters the arc light. The observation tube 200 is obliquely arranged, and the welding area is observed through a bent tube and a periscope assembly 202. The imaging area is connected to the second end of the observation tube 200, allowing the second end of the observation tube 200 to be positioned close to the equipment operating table, while increasing the observation position height for easier observation. The observation direction of the observation tube 200 can be adjusted by the rotating structure 205, enabling multi-directional fine observation of the welding process. This allows for multi-directional, equivalent close-range observation of details such as the oscillation of the welding torch 500 and welding path deviations, ensuring welding quality while improving working conditions and increasing work efficiency. On the other hand, during the welding process, the dust removal device 300 continuously extracts fumes from the protective cover 100, expelling gases from the welding cover. This facilitates observation while mitigating the harm caused by toxic gases generated during the welding process, preventing safety accidents, and improving safety during welding.

[0037] It should be understood that the observation tubes 200 are symmetrically distributed on both sides of the protective cover 100, thereby enabling comprehensive observation of the welding area of ​​the workpiece 400 from multiple directions. The observation tubes 200 can be selected according to actual needs, making operation simple and observation convenient, and effectively ensuring welding quality.

[0038] In some embodiments, reference Figure 2 The first end of the observation tube 200 is located inside the protective cover 100 and faces the plane where the bottom of the protective cover 100 is located, matching the axis of the mounting structure. A light-shielding lens 201 is provided at the first end of the observation tube 200, and the second end of the observation tube 200 is located outside the protective cover 100, filtering arc light through the light-shielding lens 201. The light-shielding lens 201 is implemented with reference to the light-shielding lens 201 of the welding protective cover 100 in the prior art, and will not be described in detail.

[0039] In some embodiments, reference Figure 4The observation device also includes a protective lens 204 disposed at the second end of the observation tube 200 and a lens group disposed within the observation tube 200. The lens group includes at least a first lens 203 and a second lens. By setting the lens group, the image can be magnified, thereby allowing for clearer observation of welding details during the welding process. It should be understood that in this embodiment, the first lens 203 and the second lens can be a convex lens and a concave lens, respectively. In other embodiments, both the first lens and the second lens can be convex lenses, with a prism group disposed between the first lens and the second lens to achieve image erection. Furthermore, the first lens 203 is slidably connected to the observation tube 200, and the observation tube 200 is provided with an adjustment mechanism for moving the first lens 203. During use, the position of the first lens 203 is adjusted by the adjustment mechanism until the image is clear, adapting to the rotation adjustment structure of the observation tube 200, thereby achieving multi-directional equivalent close-range observation of the welding process and ensuring welding quality.

[0040] In some embodiments, reference Figure 4 The bending structure includes a first bending part and a second bending part. The periscope assembly 202 includes a first lens disposed in the first bending part and a second lens disposed in the second bending part. By setting the bending structure, the observation tube 200 is in a three-section structure. The first section is located in a lower position inside the protective cover, so that the first end faces the welding area and is close to the welding area. The third section is located in a higher position, and the second end extends out of the protective cover at a suitable height for observation, avoiding the operator from bending over or kneeling, and reducing the intensity of work.

[0041] In some embodiments, reference Figure 1 and Figure 3 The protective cover 100 is provided with an inspection window for easy replacement of welding torch 500 accessories or handling of abnormal situations. The inner wall of the protective cover 100 is provided with a slide rail 101, and the inspection window is provided with a light-transmitting plate 102 that is slidably connected to the slide rail 101 on the inner wall of the protective cover 100. The light-transmitting plate 102 is provided with a force-applying structure, which drives the light-transmitting plate 102 to move and open the inspection window, making operation convenient and easy to observe the interior. The light-transmitting plate 102 can be an acrylic plate, a glass plate, etc., preferably a glass plate, but there are no restrictions in other embodiments.

[0042] In some embodiments, reference Figures 1 to 3 The dust removal device 300 includes a dust collector, a dust removal pipe connecting the dust collector and the protective cover 100 respectively, and a filter cartridge installed in the dust removal pipe or the dust collector. The dust collector draws in the dust inside the protective cover 100 through the dust removal pipe and is filtered and adsorbed by the filter cartridge. Furthermore, the dust collector is equipped with a pulse mechanism to apply vibration at a preset frequency to the filter cartridge, thereby removing the dust attached to the filter cartridge and discharging it through the air outlet.

[0043] In one embodiment, reference Figure 5 The rotating structure 205 includes a rotating seat disposed on the protective cover 100, an observation tube 200 passing through the rotating seat, and rotating shafts passing through the rotating seat on both sides of the observation tube 200. The observation tube 200 rotates relative to the rotating seat based on the rotating shafts, that is, the angle and orientation of the first end of the observation tube 200 are adjusted along the weld direction to match the welding position.

[0044] According to another aspect of the present invention, an automated welding device is also provided, which includes the above-described protective device for automated welding.
