Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, and more specifically, to an automatic welding system for electrolytic plates. Background Technology

[0002] In the electrolysis industry, electrolytic plates typically have a large area (1-3m²). 2 It is characterized by its thinness (3-7mm) and the requirement for small overhang deviation (±5mm). It belongs to large thin plates and easily deformed parts during welding.

[0003] When welding conductive rods and electrolytic plates, without suitable welding fixtures, the post-weld sag deviation often fails to meet requirements, necessitating correction or even rework. Manual high-precision assembly followed by welding is time-consuming, labor-intensive, and inefficient. Furthermore, without suitable welding fixtures, welding heat deformation is prone to occur during the welding process, requiring subsequent mechanical and manual leveling to meet final usage requirements, further increasing labor and reducing production efficiency.

[0004] The prior art disclosed in CN205702792U is a welding device for electrolytic plates in a water electrolyzer, which consists of a support base, a welding platform, a drive mechanism, a mounting frame, a pressure plate, a manual rotating wheel, and a welding torch. The welding platform is installed on the upper part of the support base and is driven by the drive mechanism located at the lower part of the support base. Mounting platforms fixed to the support base are symmetrically arranged at the left and right ends of the welding platform. The mounting frame is installed across the welding platform on the mounting platform. A pressure plate driven by the thread of the manual rotating wheel is installed in the lower middle part of the mounting frame. The welding torch is mounted on the mounting platform on one side of the welding platform through a bracket. In the prior art, the electrolytic electrode plate and the electrode frame are welded on a welding platform, and the electrode frame and the electrolytic electrode plate are automatically welded in a ring. The welding device can only weld the electrolytic electrode plate and the electrode frame, and cannot weld the electrolytic electrode plate in the middle of the conductive rod. Moreover, since the welding gun is set near the electrode frame, and the electrode frame is thicker than the electrolytic electrode plate, the welding gun cannot be directly and accurately aimed at the weld, requiring additional workpieces and increasing the cost of use. Summary of the Invention

[0005] In view of this, the present invention aims to provide an automatic welding system for electrolytic electrode plates. This addresses the problems in the prior art where electrolytic electrode plates and frames are welded on a welding platform, and the welding of the frame and plate is an automatic circular welding process. The welding device can only weld the electrolytic electrode plate and frame, and cannot weld the electrolytic electrode plate to the center of the conductive rod. Furthermore, because the welding torch is positioned close to the frame, and the frame is thicker than the electrode plate, the torch cannot be directly and accurately aimed at the weld seam, requiring additional workpieces and increasing operating costs.

[0006] To achieve the above objectives, the technical solution of the present invention is implemented as follows:

[0007] An automatic welding system for electrolytic electrode plates includes a first support, a second support, a first clamping member, a second clamping member, a welding torch, and a moving device. The two ends of the first clamping member are connected to the first and second support members respectively. The end of the first clamping member closest to the second support member is connected to the second clamping member. An electrolytic electrode plate is disposed within the first clamping member, and a conductive rod is disposed within the second clamping member. The electrolytic electrode plate and the conductive rod are welded together by the welding torch. The welding torch is connected to the moving device, which controls the movement of the welding torch to achieve the welding of the electrolytic electrode plate and the conductive rod.

[0008] This setup enables automatic welding of the conductive rod and electrode plate, while also solving the problems of welding thermal deformation and excessive post-weld sag deviation. This improves production efficiency, reduces manual labor, minimizes subsequent leveling and correction processes, and enhances economic benefits.

[0009] Furthermore, the mobile device includes a welding carriage and a guide rail. One end of the welding carriage is connected to the welding torch, and the other end of the welding carriage is slidably connected to the guide rail.

[0010] In this setup, the welding carriage slides on the guide rail, which drives the welding torch to move, improving the consistency of welding quality.

[0011] Furthermore, the first clamping member includes a welding platform and a pressure plate. The pressure plate is located on the welding platform. One end of the welding platform is connected to the first support member, and the other end of the welding platform is connected to the second support member. The electrolytic electrode plate is located between the welding platform and the pressure plate.

[0012] In this setup, the electrolytic plates are fixed to the welding platform to prevent deformation during welding.

[0013] Furthermore, the second clamping member includes a baffle, a support plate, and a fine-tuning mechanism, wherein the baffle, support plate, and fine-tuning mechanism form a "U-shaped" structure, and the conductive rod is placed within the "U-shaped" structure.

[0014] This setup is for securing the conductive rod, and also for fixing the electrolytic plate to the center of the contact surface with the conductive rod.

[0015] Furthermore, the support plate is parallel to the welding platform, one end of the support plate near the second support column is connected to the welding platform through the fine-tuning mechanism, and the other end of the support plate is connected to the baffle.

[0016] In this setup, the support plate both limits and supports the conductive rod, improving the pass rate of the weld between the conductive rod and the electrolytic electrode plate.

[0017] Furthermore, an elastic component is fitted onto one end of the baffle near the support plate. The elastic component is fixed inside the support plate, and the elastic component ensures that the conductive rod and the electrolytic electrode are in close contact.

[0018] Furthermore, the first support member includes a first rotating shaft, a first support column, and a first base. One end of the first support column is connected to the first clamping member through the first rotating shaft, and the other end of the first support column is fixedly connected to the first base.

[0019] In this setup, the first support component supports the welding platform, improving its stability and thus the welding quality.

[0020] Furthermore, the angle between the first support column and the welding platform is 30~60°.

[0021] This setup facilitates welding of electrolytic plates and conductive rods with a welding torch, improving the uniformity of welding quality and increasing welding efficiency.

[0022] Furthermore, the second support member includes a second rotating shaft, a second support column, and a second base. One end of the second support column is connected to the first clamping member through the second rotating shaft, and the other end of the second support column is fixedly connected to the second base.

[0023] In this setup, the second support member supports the welding platform, improving its stability and thus the welding quality.

[0024] Furthermore, the welding platform is provided with positioning holes, and the welding platform is connected to the pressure plate by fastening screws passing through the positioning holes.

[0025] In this setup, the positioning holes limit the position of the electrolytic electrode plate and also facilitate the clamping plate to press the electrolytic electrode plate firmly, preventing deformation of the electrolytic electrode plate during welding and improving welding quality.

[0026] Compared with existing technologies, the automatic welding system of the present invention has the following advantages:

[0027] The automatic welding system of the present invention fixes and welds the electrolytic electrode plate and the conductive rod. The welding platform is designed at 45°. During welding, the welding gun can more accurately determine the welding position. At the same time, the inclination of the conductive rod relative to the horizontal plane supports the unwelded part at the lower end of the electrolytic electrode plate, which significantly reduces the probability of thermal deformation of the thin plate during welding and improves the pass rate of the electrolytic electrode plate suspension deviation.

[0028] The automatic welding system of the present invention can realize the automatic welding of electrolytic plates and conductive rods, improve the consistency of weld quality, reduce manual labor, save labor costs, and reduce the instability factors of workers during welding, as well as the subsequent leveling and correction processes. Moreover, the automatic welding system is simple to install and has low manufacturing cost, which greatly improves economic benefits. Attached Figure Description

[0040] Specifically, the positions of the positioning holes 311 can be symmetrically distributed according to the length and width of the electrolytic plate being welded; the positioning holes 311 are used to fix the clamping plate and the fastening screws; the clamping plate requires two plates to be used together. When using it, select the appropriate positioning holes according to the size of the electrolytic plate and use the fastening screws to fix the electrolytic plate panel on the welding platform.

[0041] Specifically, multiple positioning holes 311 are provided, and these positioning holes are symmetrically arranged about the center line 313.

[0048] In this setup, since the conductive rods have different heights, widths, and thicknesses, and the electrolytic electrode panel needs to be welded to the middle part of the conductive rod during welding, the fine-tuning mechanism of the support plate can adjust it to a suitable position, while the spring-loaded baffle can ensure that the conductive rod and the electrolytic electrode panel fit tightly together.

The elastic component 411 can adjust the width / thickness / height of the conductive rod. The elastic component 411 allows the conductive rod 6 to be placed in the "U" structure and the baffle 41 to press the conductive rod 6 tightly.

[0053] More specifically, the elastic component 411 is sleeved on the baffle 41 and fixed inside the support plate. This elastic component enables the baffle to move, allowing the conductive rod to be pressed and fixed onto the support plate.

[0054] Preferably, the elastic component 411 is a spring.
