Description

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, the present invention provides a laser-dual tungsten electrode TIG composite welding device for lead alloy anode plates, which has the following advantages:

[0019] 1. This laser-tungsten electrode TIG composite welding device for lead alloy anode plates, through its designed welding mechanism, enables simultaneous double-sided welding of the anode plate and anode sheet in both vertical and horizontal positions while clamping and butt-jointing them.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1-8 A laser-tungsten electrode (TIG) composite welding device for lead alloy anode plates includes: a frame 1; a workstation plate 2; an anode plate 4; the workstation plate 2 is mounted on the frame 1 and has an installation station, on which the anode plate 4 is placed; a welding mechanism 3 for performing double-sided stable welding on the anode plate 4; the welding mechanism 3 includes a clamping mechanism and a welding component. The workstation plate 2 has multiple rollers 21 and a reverse groove 22 to provide space for reverse welding.

[0032] In this embodiment, the clamping mechanism includes a telescopic cylinder 301, which is mounted on the frame 1. The output end of the telescopic cylinder 301 is connected to a bracket 303 via a compression member. A guide rod 304 is connected to the side of the bracket 303, and a compression sleeve 305 is connected to the end face of the guide rod 304. The compression sleeve 305 abuts against the side of the anode plate 4. When the clamping mechanism is working, the output end of the telescopic cylinder 301 drives the bracket 303 to move in a predetermined direction through the transmission action of the compression member. The guide rods 304, which are symmetrically arranged on both sides of the bracket 303, move synchronously, so that the compression sleeve 305 connected to the end of the guide rod can accurately abut against the side of the anode plate 4, achieving stable clamping and centering of the workpiece to be welded. This mechanism can not only effectively prevent workpiece displacement or deformation caused by heat input during welding, but also provide a stable clamping foundation for subsequent double-sided synchronous welding, ensuring the consistency of weld position and the reliability of welding quality.

[0033] Furthermore, the compression component includes a telescopic spring 306. The output end of the telescopic cylinder 301 is connected to a slide 307. The telescopic spring 306 is sleeved inside the fixed sleeve 302 at the output end of the telescopic cylinder 301. One end of the telescopic spring 306 abuts against the slide 307, and the other end abuts against the fixed sleeve 302. The slide 307 is slidably connected to the fixed sleeve 302, and both ends of the slide 307 are connected to the weldment. The compression component has a dual function during operation: First, when the telescopic cylinder 301 begins to move, the elastic connection of the telescopic spring 306 achieves initial flexible clamping, preventing damage to the anode plate 4 from rigid impact. Second, after the compression sleeve 305 contacts the anode plate 4 and forms initial clamping, the telescopic cylinder 301 continues to retract. At this time, the slide 307 continues to move and compress the telescopic spring 306, thereby maintaining clamping force while providing the stroke and power required for subsequent actions of the weldment. This design ensures a smooth and controllable clamping process and provides reliable mechanical synchronization for the precise positioning and movement of the welding torch during welding, thereby effectively improving the stability of the welding process and the quality of the weld.

[0034] Furthermore, the welded components include a fixing plate 311, which is fixed to the frame 1. A guide groove 312 is formed on the fixing plate 311, and a spiral rod 313 is slidably connected within the guide groove 312. A laser welding gun 317 is mounted on the spiral rod 313 via a connector. A pull rod 315 is rotatably connected to the bracket 303, and the top of the pull rod 315 is rotatably connected to the spiral rod 313. Two sets of welded components are provided, symmetrically distributed around the centerline of the workstation plate 2. The guide groove 312 on the fixing plate 311 is an elongated channel with a certain inclination angle, within which the spiral rod 313 is slidably connected. The spiral rod 313, as a key component for motion conversion and transmission, has a laser welding gun 317 mounted at one end via a connector for performing high-precision laser welding operations. A pull rod 315 is rotatably connected to the bracket 303. The top of the pull rod 315 is connected to the helical rod 313 by a hinge, thereby converting the linear motion of the bracket 303 into the oblique sliding of the helical rod 313 along the guide groove 312 to cooperate with the subsequent toothed frame 310. Two sets of laser welding guns 317 can simultaneously perform synchronous welding operations on the front and back sides of the anode plate 4. This design not only effectively offsets the thermal deformation and residual stress caused by single-sided welding, greatly improving the dimensional stability and flatness of the welded structure, but also significantly improves welding production efficiency through a single clamping and double-sided simultaneous forming process, ensuring uniform penetration and consistent forming quality of the weld in the thickness direction, which is especially suitable for lead alloy anode plates that are sensitive to welding deformation.

[0035] In addition, the connector includes a retaining sleeve 318, which is snapped onto the laser welding torch 317. A collar is provided on the retaining sleeve 318, and a sliding rod 314 is slidably connected within the collar. The sliding rod 314 is connected to the frame 1 via a fixing component. The design of the connector optimizes the freedom and precision control of the laser welding torch 317's motion: the retaining sleeve 318 ensures a secure connection between the welding torch and the driving component; the sliding pair formed by the collar and the sliding rod 314 strictly limits the displacement of the welding torch in unnecessary directions, allowing it to move smoothly only along the axial direction of the sliding rod 314, i.e., the welding feed direction. This ensures that the laser welding torch 317 can accurately follow the motion trajectory driven by the screw rod 313 during welding, while effectively suppressing vibration and offset during the welding process, ensuring the stability of the laser beam focus position, thus providing crucial motion and positioning guarantees for obtaining high-quality, highly consistent laser welds.

[0036] In addition, the slide 307 has gear frames 310 connected to both ends. The gear frames 310 have teeth, and connecting gears 316 mesh with these teeth. The connecting gears 316 are fixed to both ends of the spiral rod 313. The spiral rod 313 has spiral grooves, and sliding pins 319 are slidably connected within these grooves. The sliding pins 319 are fixed to the ferrule 318. When the slide 307 moves linearly under the drive of the telescopic cylinder 301, it drives the gear frames 310 to move synchronously. The teeth on the gear frames 310 drive the meshing connecting gears 316 to rotate. The rotation of the connecting gears 316 causes the spiral rod 313 to rotate around its own axis. Because the sliding pins 319 are constrained within the spiral grooves, the rotational motion of the spiral rod 313 is forcibly converted into a precise and stable linear feed motion that drives the ferrule 318 and the laser welding torch 317 along the axial direction of the sliding rod 314 through the interaction of the spiral grooves and the sliding pins 319. This design ingeniously transforms the linear output of the single power source telescopic cylinder of the clamping mechanism into a precise action that controls the lateral movement of the welding trajectory of the laser welding gun 317. This achieves mechanical linkage and automated control of clamping, positioning and welding feed, ensuring the synchronicity and consistency of the double-sided welding process and significantly improving the integration and reliability of the welding system.

[0037] It is worth noting that the guide rod 304 is slidably connected to the extrusion sleeve 305 via a T-slot. A guide groove 308 is provided on the frame 1, and a guide pin 309 is slidably connected inside the guide groove 308, with the guide pin 309 fixed to the extrusion sleeve 305. During the clamping stage before welding, the guide rod 304 pushes the extrusion sleeve 305 in a linear motion, with the T-slot providing primary guidance. When welding is completed and the workpiece needs to be released, the telescopic cylinder 301 drives the mechanism to reset, and the guide pin 309 moves under the constraint of the guide groove 308. Because the guide groove 308 is designed with a specific orientation, such as an arc or oblique path, the guide pin 309 will be forced to slide along this predetermined trajectory, thereby causing the extrusion sleeve 305 to not only axially retract during the return process but also perform an additional, controlled offset movement, such as descent or lateral movement. This ingenious design allows the extrusion sleeve 305 to automatically create space for part removal after the anode plate 4 is released, becoming flush with or below the surface of the workstation plate 2. This allows operators or auxiliary equipment to smoothly move the workpiece horizontally out of the anode plate directly along the roller 21 without lifting it, greatly facilitating the loading and unloading of workpieces, improving work efficiency and operational safety, and achieving automated connection of clamping, welding and part removal processes.

[0038] It is worth noting that a sliding groove is provided on the fixed sleeve 302, and the slide 307 is slidably connected in the sliding groove. The output shaft of the telescopic cylinder 301 is slidably connected to the fixed sleeve 302. A control module is provided on the frame 1, which is used to control the start and stop of the laser welding gun 317. The control module is integrated on the frame 1. This control module is the core electrical control unit of the entire welding device, and it is usually composed of a programmable logic controller (PLC), a human-machine interface (HMI), relays, power supply, and input / output interfaces. The control module is electrically connected to the solenoid valve of the telescopic cylinder 301, the laser generator and its cooling system of the laser welding gun 317, position sensors, and other execution and detection components. Its core function is to precisely coordinate and control the start-up and stop-up of the laser welding gun 317, the power adjustment, and the start and stop sequence of the welding process according to the preset welding process program or operation instructions. Through this control module, the operator can realize the automated operation of the welding process, parameter setting and process monitoring, ensuring that double-sided laser welding is carried out synchronously in the correct timing and position, thereby ensuring the stable and reliable welding quality and the efficient and controllable production process. It is the main control brain for realizing the intelligent and automated welding operation of the entire device.

[0039] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0040] The working principle is as follows: First, the welded anode sheet and anode plate are placed on the installation station, namely station plate 2. Then, the retraction of the telescopic cylinder 301 is controlled, which will first drive the output shaft of the telescopic cylinder 301 to move backward. Utilizing the elastic connection of the telescopic spring 306, the pulling of the telescopic spring 306 will control the retraction of the fixed sleeve 302 and the bracket 303. The bracket 303 will then drive the two compression sleeves 305 through the two guide rods 304 to tighten and align the anode plate 4. Afterward, as the telescopic cylinder 301 continues to retract, it will drive the slide 307 to move while simultaneously compressing the telescopic spring 306. Because the compression sleeves 305 are now in contact with the anode plate 4, forming a tightening condition, the bracket 303 will no longer move and will only compress the telescopic spring 306. Afterward, when the telescopic cylinder 301 continues to pull backward, it will drive the slide 307 to move backward, which in turn will drive the toothed frame 310 to move backward. When the support 303 moves backward in the early stage, the pull rod 315 will drive the spiral rod 313 to slide inside the guide groove 312. By using the sliding of the inclined groove, the spiral rod 313 will be controlled to move downward at an angle, thereby controlling the laser welding gun 317 to be aligned with the welding position. When the spiral rod 313 moves downward at an angle, the connecting gear 316 will mesh with the teeth on the gear frame 310. Therefore, as the gear frame 310 is pulled backward, the spiral rod 313 will be driven to rotate through the gear meshing process. By using the spiral groove on the surface and the sliding pin 319, the lateral movement of the laser welding gun 317 in the tilt direction will be controlled. By using the sliding pin 319 in the spiral groove, the laser welding gun 317 will be aligned with the welding position for lateral laser welding. After welding is completed, the extension of the telescopic cylinder 301 controls the entire structure to reset and unfold. At the same time, it controls the relative unfolding of the upper and lower laser welding guns 317 to make way. After the telescopic cylinder 301 extends to a certain position, it drives the support 303 to move forward, releasing the anode plate 4. When it continues to move forward, the guide pin 309 on the extrusion sleeve 305 will slide in the guide groove 308 through the forward movement of the guide rod 304. The structure of the guide groove 308 is arc-shaped and downward. Therefore, when the guide groove 308 moves forward, the guide pin 309 will slide downward according to the limiting arc of the guide groove 308, thereby driving the extrusion sleeve 305 to move downward, thereby releasing the tail limit of the anode plate 4 and making it flush with the work station plate 2. At this time, the operator or equipment can pull out the anode plate 4 without lifting the anode plate 4. According to the multiple rollers 21, the sliding friction can be effectively controlled, making it easier to remove the anode plate 4.
