Description

Technical Field

[0001] The present application relates to the technical field of welding devices, and in particular to a copper-clad steel welding device. Background Art

[0002] Copper-clad steel is a cost-effective grounding material, combining the high corrosion resistance and electrical conductivity of copper with the high strength and low cost of steel. Copper-clad steel is currently widely used in power system grounding projects. Production of copper-clad steel requires welding two sections of copper-clad steel bar stock. The bar stock consists of a copper layer and a steel base, with the copper layer applied to the steel base.

[0003] The copper-clad steel welding device in the related technology includes a transport component and a welding mechanism. The staff or robot places the two sections of bar material on the transport component respectively. The transport component makes the two sections of bar material close to each other until the ends of the two sections of bar material abut against each other. Then the welding mechanism welds the ends of the two sections of bar material. Finally, the transport component unloads and transports the welded bar material.

[0004] However, in related art, the welding mechanism is located on one side of the bar for spot welding, which is suitable for bars with smaller diameters. Larger diameter bars can easily lead to uneven welding, affecting the weld stability. Furthermore, the relatively fixed position of the welding mechanism makes it difficult to adapt to welding bars of varying diameters. Summary of the Invention

[0005] In order to improve the uneven welding of bars and facilitate welding of bars of different diameters, the present application provides a copper-clad steel welding device.

[0006] This application provides a copper-clad steel welding device, which adopts the following technical solutions: A copper-clad steel welding device, comprising: frame; A transport assembly, the transport assembly being arranged on the frame and used for transporting bar materials; The welding mechanism includes a accommodating ring seat, a rotating assembly, a telescopic assembly, a welding gun and an end clamping assembly; the accommodating ring seat is connected to the frame, and the ends of two sections of rod stock are located in the accommodating ring seat and abut against each other; the end clamping assembly is connected to the accommodating ring seat, and the end clamping assembly clamps the end of the rod stock; the rotating assembly includes a guide ring rail, a support base block and a rotating drive source, the guide ring rail is connected to the accommodating ring seat, and the support base block is slidably connected to the guide ring rail; the telescopic assembly is connected to the support base block, and the welding gun is connected to the telescopic assembly, and the telescopic assembly drives the welding gun to move toward or away from the rod stock; the rotating drive source drives the support base block to slide along the inner wall of the guide ring rail, so that the welding gun welds the end of the rod stock in the circumferential direction.

[0007] By employing this technical solution, the transport assembly loads and transports the bar stock. Once the ends of the two bar segments abut, the end clamping assembly clamps the bar stock, enhancing its stability during welding and reducing the risk of deformation. The telescopic assembly can move the welding gun closer to or further from the bar stock, adapting to welding bars of varying diameters and enhancing its applicability. A rotating drive source drives the welding gun circumferentially along the guide rail to weld the bar stock, improving weld uniformity and post-weld stability.

[0008] Optionally, the rotating assembly further includes: A supporting ring rail, the supporting ring rail being connected to the accommodating ring seat; A rotating gear ring, wherein the rotating gear ring is rotatably connected to the supporting ring rail and the rotating gear ring is connected to the supporting base block; A driving gear, the rotation driving source is connected to the accommodating ring seat, the rotating ring gear is connected to the output shaft of the rotation driving source, and the driving gear is meshed with the rotating ring gear.

[0009] By adopting the above technical solution, the rotating driving source drives the rotating ring gear to rotate through the driving gear, and the rotating ring gear drives the supporting base block to move, so that the supporting base block slides along the guide ring rail, thereby realizing the movement of the welding gun in the circumferential direction, improving the uniformity and stability of welding, improving the welding quality, and enhancing the mechanical strength of the welding part.

[0010] Optionally, the telescopic component includes: a telescopic drive source connected to the supporting base block; A support sliding seat is slidably connected to the support base block, and the telescopic driving source drives the support sliding seat to slide, so that the welding gun moves in a direction close to or away from the bar material.

[0011] By adopting the above technical solution, the support sliding seat is slidably connected to the support base block, and the telescopic driving source drives the support sliding seat to slide, so that the welding gun can accurately move toward or away from the rod, thereby enabling the welding gun to weld rods of different diameters.

[0012] Optionally, the supporting sliding seat is connected to two distance detection members, which are respectively located on both sides of the welding gun. The two distance detection members correspond to two sections of bar material one by one, and the distance detection members are used to detect the distance between themselves and the bar material.

[0013] By adopting this technical solution, the distance detector can detect its distance from the bar, thereby obtaining information about the bar's diameter. This facilitates adjusting the distance the welding gun moves closer to the bar, improving the accuracy of the welding gun's alignment with the bar, and thus ensuring stable and consistent welding quality. Precise distance control also reduces collisions between the welding gun and the bar, extending the service life of the equipment. Furthermore, the two distance detectors, each corresponding to the two sections of bar, can independently detect whether the diameters of the two sections are consistent, reducing the problem of diameter mismatches between the two sections due to incorrect loading.

[0014] Optionally, a grinding assembly is provided on the supporting base block, and the grinding assembly includes: a driving source connected to the supporting base block; A bearing slide, the bearing slide being slidably connected to the supporting base block; The grinder is arranged on the bearing slide, and the driving source pushes the bearing slide to slide, so that the grinder approaches or moves away from the rod, and the grinder grinds the end of the rod.

[0015] By adopting this technical solution, the grinder removes the copper layer on the bar surface before welding, which helps improve welding performance. After welding, the grinder can polish the welded area to remove slag and burrs, improving the flatness and aesthetics of the weld surface. The drive source controls the grinder's feed, ensuring precise control of the grinding process and reducing damage to the bar due to excessive grinding.

[0016] Optionally, the grinder includes a grinding drive source and a grinding head, the bearing slide is connected to a pressure sensor, the grinding drive source is connected to the pressure sensor, the grinding head is connected to the output shaft of the grinding drive source, and the pressure sensor is used to detect the pressing force between the grinding head and the rod.

[0017] By adopting the above technical solution, the grinding drive source is connected to the pressure sensor to ensure that the pressing force between the grinding head and the bar is effectively controlled, which not only improves the accuracy of the grinding process, but also reduces the problem of uneven grinding or damage to the bar caused by excessive or insufficient pressure. The pressure sensor monitors the contact pressure between the grinding head and the bar in real time, ensures the grinding quality of the weld, and improves the reliability of the final product. In addition, after welding is completed, the driving source pushes the grinder close to the bar so that the grinding head applies a pressing force to the bar. The pressure sensor detects whether the pressing force reaches a predetermined detection value, thereby judging whether the bar welding meets the standard. If the welding does not meet the standard, repair welding is required. In the related art, for the detection of bar welding strength, the bar is generally unloaded and transported after the bar welding is completed, and then the bar is transported and clamped to a specific detection mechanism for detection. However, transportation and clamping will result in additional processes, which takes a certain amount of time and easily reduces processing efficiency. However, the present application can detect immediately after the bar welding is completed, saving time for transportation and clamping and improving processing efficiency.

[0018] Optionally, a blowing assembly is provided on the containing ring seat, and the blowing assembly includes a fixed seat and a cooling air duct, the fixed seat is connected to the containing ring seat, the cooling air duct is connected to the fixed seat, the cooling air duct is connected to an external air source, the cooling air duct faces the end of the rod, and the cooling air duct is used to blow air toward the end of the rod.

[0019] By adopting the above technical solution, after the bar is welded, it is necessary to wait until the bar is cooled and shaped before grinding. The cooling air duct can quickly blow air to the end of the bar after welding is completed, accelerating the cooling process of the bar, reducing waiting time, facilitating subsequent grinding operations, and improving processing efficiency.

[0020] Optionally, a collection component is provided on the frame, and the collection component includes a collection hopper and an aggregate filter box. The collection hopper is connected to the containing ring seat, and the collection hopper is communicated with the aggregate filter box. The aggregate filter box is externally connected to a negative pressure exhaust source, and the cooling air duct blows the grinding debris toward the collection hopper.

[0021] By adopting the above technical solution, the cooling air duct blows the debris generated by grinding to the collection hopper, reducing the splashing of debris. At the same time, the aggregate filter box further improves the debris collection efficiency by connecting to an external negative pressure exhaust source, ensuring a clean working environment.

[0022] Optionally, the frame is provided with an abutment mechanism, the abutment mechanism is located between the transport assembly and the welding mechanism, and two groups of abutment mechanisms are provided, and the two groups of abutment mechanisms are respectively located on both sides of the welding mechanism; The abutment mechanism includes a movable slide, a clamping assembly and a point detection assembly; the movable slide is connected to the frame, the clamping assembly is connected to the movable slide, and the movable slide drives the clamping assembly to move toward the direction close to the accommodating ring seat; the point detection assembly is connected to the frame, and the point detection assembly detects the position of the bar; when the point detection assembly detects that the bar has reached a predetermined position, the clamping assembly clamps the bar, and the movable slide makes the ends of the two sections of the bar abut against each other.

[0023] By adopting this technical solution, two abutment mechanisms are located on either side of the welding mechanism. These abutment mechanisms precisely control the joining process of the two bar sections, ensuring accurate positioning of the bars before welding, thereby improving the precision and reliability of the joining process. The point detection assembly monitors the position of the bars in real time, ensuring that the clamping assembly can grasp the bars at the appropriate time, reducing weld defects caused by positional deviations. The movable slide drives the clamping assembly for precise movement, ensuring that the ends of the two bar sections abut tightly, enhancing the stability and consistency of the weld.

[0024] Optionally, the clamping assembly includes a clamping drive source, a tightening telescopic rod and a spring piece, the clamping drive source is connected to the movable slide, the tightening telescopic rod is connected to the clamping drive source, the spring piece is connected to the tightening telescopic rod, two spring pieces are provided opposite to each other, and the clamping drive source enables the two spring pieces to clamp the bar material; The point detection component includes a support plate, an infrared transmitter and an infrared receiver. The support plate is connected to the frame. The infrared transmitter and the infrared receiver are both connected to the support plate. The infrared transmitter and the infrared receiver are arranged opposite to each other. The infrared receiver is used to receive the signal emitted by the infrared transmitter. The bar passes between the infrared transmitter and the infrared receiver.

[0025] By adopting the above technical solution, when the rod passes between the infrared transmitter and the infrared receiver, the rod can block the infrared receiver from receiving the signal emitted by the infrared transmitter. This indicates that the rod has reached the predetermined point. The clamping drive source drives the spring clip to clamp the rod by pressing the telescopic rod, and then the sliding table drives the rod to move in the direction close to the accommodating ring seat, so that the ends of the two sections of the rod are pressed tightly, which is conducive to subsequent welding operations.

[0026] In summary, this application has at least one of the following beneficial effects: 1. The rotating drive source drives the rotating ring gear to rotate, and the rotating ring gear drives the supporting base to slide along the guide ring rail, so that the welding gun rotates around the bar, achieving uniform welding of the bar in the circumferential direction, improving welding quality and stability; the telescopic drive source can move the welding gun toward or away from the bar, so that bars of different diameters can be welded, improving adaptability; 2. Before welding, the grinder removes the copper layer on the surface of the bar, which can improve subsequent welding performance. After welding, the driving source pushes the grinder, causing the grinder to apply a clamping force to the bar. The pressure sensor detects the clamping force applied to the bar. The pressure sensor detects whether the clamping force reaches the predetermined detection value, thereby determining whether the bar welding meets the standards. If the welding does not meet the standards, repair welding is required. If the welding meets the standards, the grinder grinds the welding area of ​​the bar to remove welding slag and burrs, making the welding area of ​​the bar smoother. 3. The cooling air duct blows air into the bar, accelerating the cooling of the welding area of ​​the bar, reducing the time waiting for the welding area to cool before grinding, and improving processing efficiency. The cooling air duct blows the debris generated by grinding into the collection hopper, reducing debris splashing, improving debris collection efficiency, and ensuring a clean working environment.

In this embodiment, the distance detecting member 46 is specifically a distance sensor. Two distance detecting members 46 are provided.

[0042] Before welding, the rotating assembly 42 drives the grinder 473 to rotate around the axis of the bar through the support base 422. The grinder 473 grinds the end of the bar to remove the copper layer at the end of the bar, which is beneficial to improving the quality and strength of subsequent welding.

Debris is generated during the grinding process. The air blown out of the cooling air duct 482 is directed toward the collection hopper 51, so that the debris generated by grinding is blown into the collection hopper 51. The negative pressure exhaust source generates negative pressure in the aggregate filter box 52, which is conducive to the collection of debris in the aggregate filter box 52. After the aggregate filter box 52 collects a certain amount of material, the aggregate filter box 52 is removed to clean the debris.

[0045] The implementation principle of a copper-clad steel welding device in Example 1 of the present application is as follows: the transport component 2 loads the bar material so that the two sections of the bar material abut against the containing ring seat 41, and the end clamping component 45 clamps the end of the bar material to improve the stability of the end of the bar material. The driving source 471 is pushed to make the grinder 473 abut against the bar material, and the grinder 473 grinds the bar material to remove the copper layer on the surface of the bar material. Then, the rotating component 42 causes the welding gun 44 to rotate around the axis of the bar material to weld the ends of the two sections of the bar material. After welding is completed, the driving source 471 is pushed to make the grinder 473 apply a clamping force to the bar material, and the pressure sensor 474 determines whether the welding meets the standards. If the welding meets the standards, the grinder 473 grinds the welding area of ​​the bar material to remove the welding slag and burrs in the welding area of ​​the bar material and improve the flatness of the welding area of ​​the bar material.

The two groups of abutment mechanisms 3 correspond one to one with the two sections of bar stock. The movable slide 31 can drive the two ends of the bar stock to abut against each other.

[0049] The implementation principle of a copper-clad steel welding device in Example 2 of the present application is as follows: the transport component 2 transports the bar material. When the infrared receiver 333 does not receive the light signal emitted by the infrared transmitter 332, it indicates that the end of the bar material is at a predetermined point, and the transport component 2 stops transporting. The clamping drive source 321 clamps the bar material by pressing the telescopic rod 322, and the movable slide 31 moves the bar material in the direction close to the accommodating ring seat 41 until the ends of the two sections of the bar material abut against each other. The abutment mechanism 3 can make the abutment and alignment of the ends of the two sections of the bar material more precise, and make the abutment of the ends of the two sections of the bar material tighter, thereby improving the accuracy of the bar ends when docking.

[0050] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
