[0067] As described in the background art, an aluminum-sheathed cable is an efficient cable suitable for various industrial and civil power transmission requirements. During the production process of an aluminum-sheathed cable, it is necessary to connect the aluminum strips wound around the outer periphery of the cable through welding to ensure the sealing and reliability of the aluminum-sheathed cable. At present, the detection of the welding state during the welding process of the cable sheath mainly depends on manual judgment, including manually observing the weld seam and the position of the welding torch, and manually adjusting the position of the welding torch to complete production. However, manual operation is prone to fatigue, reducing the welding reliability, and the accuracy of manually detecting welding defects is relatively low.

[0068] After research by the utility model inventors, it is found that the reasons for the above problems include: the welding state during the welding process of the cable sheath includes the molten pool state, the detection of the blunt edge and burr defects on the surface of the welding electrode. The welding electrode is usually a tungsten needle, and the accuracy of relying on manual visual inspection during this welding process is relatively low, which often leads to downtime to replace the tungsten needle, reducing the production efficiency of the cable sheath.

[0069] In view of the above technical problems, the embodiment of the present utility model provides a continuous welding system, which includes a working base, a first welding device, a first photographing device and a control device. It can not only control the welding device to automatically weld the cable sleeve with a pipe gap through the control device, but also obtain the weld position information of the cable sleeve, the image information of the welding molten pool, the image information of the welding electrode and / or the image information of the weld surface through the photographing device mounted on the working base and located on the side of the welding device. Compared with manual visual observation of the welding state to identify weld defects, the detection accuracy of welding electrode defects and weld defects is significantly improved.

[0070] In order to make the above objects, features and advantages of the embodiments of the present utility model more obvious and understandable, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0071] Refer to Figures 1 to 3, the continuous welding system provided by the embodiment of the present utility model includes a working base 100, a first welding device 200, a first photographing device 300 and a control device; the first welding device 200 is erected on the working base 100, the first welding device 200 is signal-connected to the control device, and the control device controls the first welding device 200 to weld a cable sleeve 400 with a pipe gap located on the working base 100. For example, the cable sleeve 400 is an aluminum sleeve; the first photographing device 300 is erected on the working base 100 and is located on the side of the first welding device 200. The first photographing device 300 is used to obtain the position information of the weld 800 of the cable sleeve 400, the image information of the welding molten pool, the image information of the welding electrode and / or the image information of the surface of the weld 800. Among them, the image information of the surface of the weld 800 may include incomplete welding, protrusions and / or pits on the welding surface of the cable sleeve 400. Exemplarily, the welding electrode is a tungsten needle; the first photographing device 300 includes a first photographing group 310 and a second photographing group 320. Both the first photographing group 310 and the second photographing group 320 are signal-connected to the control device and are respectively located on both sides of the first welding device. The first photographing group 310 is used to obtain the weld position information and / or the image information of the welding molten pool, and the second photographing group 320 is used to obtain the image information of the welding electrode and / or the image information of the weld surface.

[0072] In this way, the control device can control the first welding device 200 to automatically weld the cable sleeve 400 with a pipe gap, and the first photographing device 300 erected on the working base 100 and located on the side of the first welding device 200 is used to obtain the position information of the weld 800 of the cable sleeve 400, the image information of the welding molten pool, the image information of the welding electrode and / or the image information of the surface of the weld 800. Compared with the manual visual observation of the welding state to identify the weld 800 defects, the detection accuracy of the welding electrode defects and the weld 800 defects is significantly improved.

[0073] As an example, a forming die base 120 is provided on the working base 100. The forming die base 120 has an annular opening, and a clamping ring is installed on the annular opening. The clamping ring is configured to be clamped radially on the outer periphery of the cable sleeve 400. Further, a plurality of forming die bases 120 are provided and are clamped on the outer periphery of the cable sleeve 400 at intervals along the axial direction of the cable sleeve 400. In this way, the circumferential limit of the cable sleeve 400 is carried out through the forming die base 120 with an annular opening, which ensures the structural stability of the cable sleeve 400 before welding and is conducive to the subsequent welding of the first welding device 200, that is, the cable pipe is pressed by the forming die base 120 with a clamping ring to ensure the tight combination of the weld 800 of the cable pipe sleeve.

[0074] Further, the continuous welding system further includes a conveying device, which is drivingly connected to the cable sleeve 400. There is a gap between the cable sleeve 400 and the snap ring on the forming die base 120. The conveying device is used to drive the cable sleeve 400 to move in a direction parallel to the working base 100, so as to effectively weld all the axial tube gaps of the cable sleeve 400 by the first welding device 200.

[0075] In more examples, an observation plate 130 is further provided on the working base 100. The observation plate 130 is provided with a mounting opening, and an observation window is installed in the mounting opening. The observation plate 130 is arranged close to the first welding device 200 and is located on the side of the cable sleeve 400, so as to facilitate the operator to observe the welding situation with the naked eye.

[0076] In some embodiments, the continuous welding system further includes a first lifting device 500. The first lifting device 500 is signal-connected to the control device. The first lifting device 500 includes a first fixing member 510 and a first lifting member 520. The first fixing member 510 is fixed to the working base 100 to serve as the mechanical installation foundation of the first lifting device 500. The first fixing member 510 has a first moving cavity. The first lifting member 520 is movably connected to the first moving cavity. The first lifting member 520 is drivingly connected to both the first welding device 200 and the first photographing device 300. The control device controls the first lifting member 520 to move relative to the first moving cavity to drive the first welding device 200 and the first photographing device 300 to lift.

[0077] In more embodiments, the continuous welding system further includes a second lifting device 600. The second lifting device 600 is signal-connected to the control device. The second lifting device 600 includes a second fixing member 610 and a second lifting member 620.

The control device controls the second lifting member 620 to move relative to the second moving cavity to drive the first welding device 200 to lift.

[0079] As a possible implementation manner, the control device controls the second lifting device 600 to drive the first welding device 200 to lift, so that the first distance between the welding electrode and the tube gap is within a preset range. For example, 5-10 mm, which can be 5 mm or 7 mm or 10 mm. The first distance is calculated by the control device according to the image information of the welding molten pool and the image information of the welding electrode.

[0080] In a possible implementation manner, the first welding device 200 includes a first welding gun 210 and a second welding gun 220, which are spaced apart and mounted on the work base 100 and are located above the cable sheath 400. The first welding gun 210 and the second welding gun 220 are both connected to the control device signal. The first welding gun 210 is used for the initial pre-welding of the cable sheath 400, and the second welding gun 220 is used for the secondary welding of the cable sheath 400 to obtain a higher quality weld 800. In this embodiment, the second lifting device 600 includes a first lifting module and a second lifting module, both of which are connected to the control device signal and are respectively connected to the first welding gun 210 and the second welding gun 220 by transmission to separately and accurately realize the height adjustment of the two welding guns.

[0081] With such a configuration, the welding efficiency of the cable sleeve 400 is relatively high. The welding system uses two welding guns to weld simultaneously during the welding process. First, the first welding gun 210 performs pre-welding and priming on the cable sleeve 400, and then the second welding gun 220 performs repair welding to obtain a high-quality weld 800. The welding process can be a combination of AC and DC welding, that is, the first welding gun 210 uses an AC welding process, and the second welding gun 220 uses a DC welding process.

[0082] In some other possible embodiments, the first camera device 300 includes a first camera group 310 and a second camera group 320, both of which are connected to the control device signal and are respectively located on both sides of the first welding device 200, the first camera group 310 is transmission connected to the first lifting member 520, and the first camera group 310 is used to obtain the position information of the weld 800 and / or the image information of the welding pool; the second camera group 320 is transmission connected to the first lifting member 520, and the second camera group 320 is used to obtain the image information of the welding electrode and / or the image information of the surface of the weld 800.

[0083] As an example, the first shooting device 300 also includes a first translation mechanism 330 and a first guide structure 340; the first translation mechanism 330 includes a first driving member 331, a screw rod and a moving block, the first driving member 331 drives the connecting screw rod, the moving block is provided with a screw hole, and the moving block is threadedly connected to the screw rod through the screw hole.

[0084] The first camera group 310 is transmission-connected to the moving block, and the guide structure is located below the moving block, which is used to limit the rotation of the moving block and guide the moving block to move along a direction parallel to the axial direction of the cable sleeve 400 under the drive of the first driving member 331, so as to adjust the distance between the first camera group 310 and the weld 800.

[0085] In another example, the first camera group 310 includes a first camera 311 and a second camera 312. The first camera 311 and the second camera 312 are respectively driven and connected to the moving block through a first rod and a second rod; both the first camera 311 and the second camera 312 are signal-connected to the control device; the first camera 311 and the second camera 312 are respectively used to obtain the position information of the weld seam 800 and the image information of the welding molten pool.

[0086] In more embodiments, the continuous welding system further includes a second translation mechanism 110. The second translation mechanism 110 is installed between the working base 100 and the first welding device 200, and the second translation mechanism 110 is signal-connected to the control device.

[0087] The control device controls the second translation mechanism 110 to drive the first welding device 200 to translate radially along the cable sleeve 400 according to the position information of the weld seam 800 obtained by the first camera 311, so that the first welding device 200 is aligned with the pipe gap of the cable sleeve 400.

[0088] Further, the second translation mechanism 110 includes a first moving module 112 and a first translation base 111.

The first welding device 200 includes a first welding torch 210 and a second welding torch 220 both drivingly connected to the first translation base 111. The first moving module 112 drives the first translation base 111 to drive the first welding torch 210 and the second welding torch 220 to move back and forth radially along the cable sleeve 400.

[0089] In other possible embodiments, the second camera group 320 includes a third camera 321 and a fourth camera 322. The third camera 321 and the fourth camera 322 are respectively driven and connected to the moving block through a third rod and a fourth rod.

[0090] Both the third camera 321 and the fourth camera 322 are signal-connected to the control device. The third camera 321 and the fourth camera 322 are respectively used to obtain the image information of the welding electrode and the image information of the surface of the weld seam 800.

The alarm unit is signal-connected to the control device; when the control device compares the image information of the welding electrode obtained by the third camera 321 with any image in its preset surface defect image library and they are consistent, the control device controls the alarm unit to give an alarm.

[0092] In this way, during a long welding process, the weld seam 800 of the cable sleeve 400 sometimes deviates from the position of the tungsten needle of the welding electrode of the welding torch, resulting in abnormal welding. The position of the weld seam 800 is captured online in real time by the first camera 311, and the second translation mechanism 110 of the welding system is controlled in real time through the control device to achieve the tracking control of the weld seam 800.

[0093] Moreover, after the welding is completed, the quality of the welding surface is detected by the fourth camera 322 at the rear end. When surface defects such as pits, protrusions, and / or lack of fusion appear on the welding surface, an alarm is given in time through the software program of the control device and recorded.

[0094] Not only that, the embodiment of the present utility model realizes the detection function of the welding molten pool and the surface state of the welding electrode. Exemplarily, the welding electrode is a tungsten needle, and the second camera 312 and the third camera 321 are used to capture the state of the molten pool and the tungsten needle in real time. The control device compares the tungsten needle image information obtained by the camera with the tungsten needle surface defect database pre-established by itself, automatically identifies defects such as hairline defects on the tungsten needle surface and issues an alarm signal; furthermore, by combining the two cameras and automatically calculating the working height from the tungsten needle to the weld seam 800 through visual AI imaging, when the welding height increases due to tungsten needle consumption, the first lifting device 500 and the second lifting device 600 can be automatically activated and controlled, so as to realize the autonomous adjustment of the welding height.

[0095] In other possible embodiments, the welding system further includes a display device 700 signal-connected to the control device. The display device 700 includes a first display 710.

[0096] In more embodiments, the continuous welding system includes two welding systems constituted by any of the above embodiments, namely a first welding system and a second welding system, and the devices in the welding systems are arranged on the same work base 100. For example, the second welding system includes a second welding device 230, a third lifting device 530, and a fourth lifting device 630. The second welding device 230 is arranged on the work base 100. The second welding device 230 includes a third welding gun 231 and a fourth welding gun 232.

In the normal production process, the two welding systems are used in one and standby, and have manual and automatic switching functions. After the welding system mode selection is completed by the control device, the welding system is started. When an abnormality is detected in a certain set of welding guns or the tungsten needle is exhausted and a defect appears on the surface of the tungsten needle, it can automatically switch to another set of welding systems. The switching action can be controlled by a software program to achieve seamless connection and significantly improve welding production efficiency.
