Description

Technical Field

[0001] This invention belongs to the field of aluminum electrolytic anode component processing technology, and particularly relates to a fully automated production line for direct welding of aluminum and steel. Background Technology

[0002] The anode guide rod assembly is the core current-carrying structural component of the prebaked anode aluminum electrolytic cell. It mainly consists of three core units: anode carbon block, aluminum guide rod, and anode steel claw. It plays a crucial role in smoothly and with low loss transmitting the large current from the anode busbar of the electrolytic cell to the anode carbon block.

[0003] Currently, the commonly used anode steel claw structure in the industry mainly includes a crossbeam, cylindrical steel claws fixed to the crossbeam by friction welding, and aluminum guide rods fixed above the crossbeam by welding. The aluminum-steel dissimilar metal welding of the aluminum guide rods and the anode steel claw crossbeam has long relied on manual welding as the core operation mode. The standard process is as follows: first, the surface treatment of the parts of the steel claw crossbeam to be welded is performed manually, such as grinding and cleaning; then, an aluminum-steel transition layer is manually deposited; after the transition layer is formed, the aluminum guide rods are manually butt-welded onto the aluminum layer surface. In addition, auxiliary processes such as the reinforcement of the anode guide rod assembly with steel strips and the welding of aluminum-steel composite plates and stiffeners are also completed manually in a discrete, single-station manner.

[0004] As the aluminum electrolysis industry develops towards large-scale, low-energy consumption, and high-safety directions, the existing manual processing mode can no longer meet the industry's production needs and has certain drawbacks: manual welding is limited by uncontrollable factors such as the operator's technical level, work experience, and working conditions, making it impossible to accurately and stably control key welding parameters. This easily leads to fatal defects such as incomplete fusion, cracks, porosity, and slag inclusions in the weld. Not only are the weld formations rough and the appearance inconsistent, but it also leads to a decrease in the conductivity and insufficient mechanical strength of the welded joint. The current welding processing of anode guide rod assemblies is a multi-process discrete operation mode, including crossbeam steel strip welding, aluminum guide rod butt welding, aluminum-steel composite plate and stiffener pre-welding, and reinforcement structure welding. The current process involves multiple independent workstations, with workpiece transfer and loading / unloading relying entirely on manual labor, forklifts, or overhead cranes. This not only requires a large amount of manual labor for workpiece handling, clamping, and positioning, resulting in extremely high labor intensity, but more seriously, the repeated transfer and clamping of workpieces between multiple workstations further affects welding quality and the subsequent assembly accuracy of the electrolytic cell. In summary, developing a fully automated aluminum-steel direct welding production line that enables parallel processing of multiple processes and a fully automated closed-loop process to address the numerous pain points of existing technologies, such as unstable welding quality, low production efficiency, insufficient automation, and high labor intensity, has become an urgent technical challenge in the current aluminum electrolytic anode component processing field.

[0016] Compared with the prior art, the advantages and positive effects of the present invention are as follows: This invention provides a fully automated aluminum-steel direct welding production line, achieving continuous, streamlined operation across all processes and overcoming the efficiency bottleneck of traditional discrete processes. Through a closed-loop conveyor line combined with a loop conveyor path, the entire process, including steel strip welding, aluminum guide rod butt welding, aluminum-steel composite plate-rib pre-welding, and reinforcement welding, is connected in series into a continuous production line. This replaces the traditional discrete workstation mode of manual transfer, eliminating workpiece transfer and waiting time between processes. It achieves continuous, rhythmic production of anode guide rod welding, significantly reducing the processing cycle of a single workpiece and significantly increasing production capacity. A unified clamping and positioning benchmark solves the problem of precision loss due to repeated clamping in multiple processes at its root. Utilizing the established beam reinforcement welding device and the aluminum-steel direct welding assembly device, both employ identical material handling methods and workpiece clamping and positioning structures. Workpieces only need to be clamped once in the core welding process to complete the entire process, avoiding positioning benchmark deviations caused by repeated clamping and transfer in traditional multi-station operations, and significantly improving efficiency. Precise control of welding form and position tolerances ensures the coaxiality and flatness of the aluminum guide rod and the steel claw beam, providing structural support for the stability of welding quality. Parallel processing mode improves processing efficiency: through the coordinated design of the aluminum-steel direct welding assembly and the external supporting stiffener composite plate pre-welding device, parallel synchronous operation of the aluminum guide rod body welding and the aluminum-steel composite plate-stiffener pre-welding is achieved. While the aluminum-steel direct welding assembly completes the automatic welding of the aluminum guide rod, the stiffener composite plate pre-welding device simultaneously completes the pre-welding of the aluminum-steel composite plate and stiffener, reducing the waiting time of the processing steps to a certain extent and ensuring the processing progress. This device is rationally designed, simple in structure, and easy to process. It adopts a streamlined production line design and a multi-process parallel processing mode, realizing a fully automated closed-loop operation of the anode guide rod assembly aluminum-steel welding process. This eliminates quality fluctuations in manual welding and accuracy deviations in multi-process clamping, improving welding quality stability and production efficiency, reducing labor intensity and production safety risks, and meeting the production and processing needs of the aluminum electrolysis industry.

Detailed Implementation

[0019] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example: A fully automated aluminum-steel direct welding production line is used for the automated welding of anode guide rod assembly 1 for aluminum electrolysis, such as... Figure 1 As shown, the anode guide rod assembly 1 includes an anode steel claw prefabricated component 1a with a crossbeam 1a1 and a cylindrical steel claw 1a2, an aluminum guide rod 1b, a reinforcing steel strip 1c, an aluminum-steel composite plate 1d, and a stiffening plate 1e. The specific configuration of the anode guide rod assembly 1 is based on existing mature and conventional technologies. This embodiment aims to solve its welding and processing problems, such as... Figures 2-11 As shown, the production line includes a closed-loop conveyor line 2, an integrated loading and unloading device 3, a crossbeam reinforcement welding device 4, an aluminum-steel direct welding assembly device 7, and a stiffener composite plate pre-welding device 8. The closed-loop conveyor line 2 is equipped with a forward conveyor belt 21 and a return conveyor belt 22 connected end to end. Several workpiece racks 23 are set on both the forward conveyor belt 21 and the return conveyor belt 22. The integrated loading and unloading device 3 is arranged on the outside of the end connection of the closed-loop conveyor line 2. It is used to load the anode steel claw prefabricated parts 1a onto the workpiece racks 23 of the closed-loop conveyor line 2, and to unload the finished anode guide rod assembly 1, which has been welded in all processes, from the workpiece racks 23 of the closed-loop conveyor line 2. The crossbeam reinforcement welding device 4 moves along the forward direction of the closed-loop conveyor line 2. The conveyor belts 21 are arranged sequentially to complete the automated welding of the reinforcing steel strips 1c on both sides of the crossbeam 1a1 of the anode steel claw prefabricated component 1a. Of course, the number of them can be set freely according to the specifications in the factory. The aluminum-steel direct welding assembly device 7 is arranged along the loop conveyor belt 22 of the closed-loop circulating conveyor line 2, and forms a closed loop connection with the conveying path of the crossbeam reinforcing welding device 4. It is used to complete the aluminum-steel direct welding of the aluminum guide rod 1b and the anode steel claw crossbeam 1a1, as well as the welding operation of the reinforcing component and the aluminum guide rod 1b. The rib plate composite plate pre-welding device 8 is arranged outside the aluminum-steel direct welding assembly device 7 to simultaneously complete the pre-welding operation of the aluminum-steel composite plate 1d and the rib plate 1e, and transfer the pre-welded reinforcing component to the welding station of the aluminum-steel direct welding assembly device 7. In the above process: Achieving continuous, fully automated production line operation breaks through the efficiency bottleneck of traditional discrete processes. Through the closed-loop conveyor line 2 combined with the loop conveyor belt 22, the entire process, including welding of reinforcing steel strips 1c, butt welding of aluminum guide rods 1b, pre-welding of aluminum-steel composite plates 1d and stiffeners 1e, and reinforcement welding, is connected in series into a continuous production line. This replaces the traditional discrete workstation mode of manual transfer, eliminating workpiece transfer and waiting time between processes. It achieves continuous, rhythmic production of the anode guide rod assembly 1, significantly reducing the processing cycle of a single workpiece and significantly increasing production capacity. Unified clamping and positioning benchmarks fundamentally solve the accuracy control problem caused by repeated clamping in multiple processes. Utilizing the established beam reinforcement welding device 4 and the aluminum-steel direct welding assembly device 7, both employ identical material handling methods and workpiece clamping and positioning structures. In the core welding process, the workpiece only needs to be clamped once to complete the entire process, avoiding the positioning benchmark deviation caused by repeated clamping and transfer in traditional multi-station operations, and significantly improving the control of welding form and position tolerances. The precision of the control ensures the coaxiality and flatness of the aluminum guide rod 1b and the steel claw beam 1a1, providing structural support for the stability of welding quality. The parallel processing mode improves processing efficiency: through the coordinated design of the aluminum-steel direct welding assembly 7 and the outer supporting stiffener composite plate pre-welding device 8, the parallel synchronous operation of the main welding of the aluminum guide rod 1b and the pre-welding of the aluminum-steel composite plate 1d and stiffener 1e is realized. While the aluminum-steel direct welding assembly 7 completes the automatic welding of the aluminum guide rod 1b, the stiffener composite plate pre-welding device 8 simultaneously completes the pre-welding of the aluminum-steel composite plate 1d and stiffener 1e, reducing the waiting time of the processing steps to a certain extent and ensuring the processing progress. This device is reasonably designed, simple in structure, and easy to process. It adopts a streamlined production line design and a multi-process parallel processing mode, realizing a fully automated closed-loop operation of the aluminum-steel welding of the anode guide rod group 1. This eliminates quality fluctuations in manual welding and precision deviations in multi-process clamping, improves welding quality stability and production efficiency, reduces labor intensity and production safety risks, and meets the production and processing needs of the aluminum electrolysis industry.

[0022] To facilitate the loading of the anode steel claw preform 1a and the convenient unloading of the formed workpiece, and to optimize the performance of the equipment, the integrated loading and unloading device 3 includes a truss 31. A movable frame 32, adjustable horizontally and vertically, is mounted above the truss 31. A first vertical screw lifting mechanism 33 is mounted on the rear side of the movable frame 32. A crossbeam 34 is mounted at the moving end of the first vertical screw lifting mechanism 33. Clamping cylinders 35 are mounted on both sides of the crossbeam 34. The specific working method is described as follows: The clamping cylinder 35 clamps and releases the workpiece, and in conjunction with the horizontal and vertical movement of the moving frame 32 and the vertical lifting of the first vertical screw lifting mechanism 33, the loading and unloading of the workpiece is completed. That is to say, the clamping cylinder 35 clamps the external anode steel claw preform 1a and places it on the workpiece rack 23 of the outgoing conveyor belt 21 of the closed-loop conveyor line 2. At the same time, it can also remove the formed workpieces loaded on the workpiece rack 23 of the return conveyor belt 22 and transport them to the workpiece receiving area. The operation is simple and convenient and highly practical.

[0023] To perform reinforcing welding on both sides of the anode steel claw preform 1a, specifically welding reinforcing steel strips 1c at the geometric center of both sides of the crossbeam 1a1, a first welding robot 12, longitudinally adjustable, is installed on one side of the crossbeam reinforcing welding device 4 to perform the welding operation of the reinforcing steel strips 1c. The crossbeam reinforcing welding device 4 includes a first gripping and transferring mechanism 41, a first feeding mechanism 5, and a first adaptive positioning and clamping mechanism 6. The first gripping and transferring mechanism 41 is used to grip and transfer the anode steel claw preform 1a from the closed-loop conveyor line 2 into the first adaptive positioning and clamping mechanism 6. The first adaptive positioning and clamping mechanism 6 is used to grip and transfer the anode steel claw preform 1a from the closed-loop conveyor line 2 into the first adaptive positioning and clamping mechanism 6. The workpiece 1a is positioned and clamped, and its free adjustment in the horizontal and vertical directions can adapt to workpieces of different specifications. Its rotation adjustment in the horizontal direction can facilitate the adjustment of the welding position of the workpiece, improving the work process. The first welding robot 12 is used to weld reinforcing steel strips 1c on both sides of the crossbeam 1a1 of the anode steel claw preform 1a. The first gripping and transferring mechanism 41 is also used to send the workpiece after the reinforcement welding is completed back to the closed-loop circulation conveyor line 2. For the established first gripping and transferring mechanism 41: the first gripping and transferring mechanism 41 includes a U-shaped worktable 411, on which a lifting frame 412 is provided. The corners of the lifting frame 412 are provided with A lifting rod 413 is provided, and a lifting cylinder 414 is provided on the inner side of the lifting rod 413. A horizontal adjusting slide bar 415 is provided above the lifting frame 412, and a horizontal plate 416 is provided above the horizontal adjusting slide bar 415. A concave seat 417 is provided on the horizontal plate 416, and a drive motor 418 is provided on the concave seat 417. A drive gear 419 is provided at the output end of the drive motor 418. An extension rod 4110 that can slide longitudinally relative to the horizontal plate 416 is provided on the inner side of the concave seat 417. A rack 4111 is provided on the inner side of the extension rod 4110, and a first finger cylinder 4112 is provided at the end of the extension rod 4110. The specific working method is described below. The description is as follows: When the first gripping and transferring mechanism 41 is running, the drive motor 418 drives the drive gear 419 to rotate, which in turn drives the extension rod 4110 to extend and retract longitudinally in conjunction with the rack 4111. In conjunction with the vertical lifting of the lifting frame 412 under the action of the lifting cylinder 414, and the horizontal movement adjustment of the transverse plate 416, the gripping and transfer of workpieces between workstations can be realized. For example, the anode steel claw preform 1a can be picked up and sent to the first adaptive positioning clamping mechanism 6, and the workpiece after the reinforcement steel strip 1c has been welded can be transported to the closed-loop circulating conveyor line 2. Both processing actions are performed by the first gripping and transferring mechanism 41, which improves the functionality of the device.

[0024] To facilitate the loading and unloading of the anode steel claw preform 1a and improve production efficiency, the first loading mechanism 5 includes a π-shaped upright frame 51. A longitudinal sliding assembly 52 is mounted above the upright frame 51. A longitudinal transfer frame 53 is mounted at the moving end of the longitudinal sliding assembly 52. ​​A second vertical screw lifting mechanism 54 is mounted on one side of the longitudinal transfer frame 53. A mounting frame 55 is mounted at the moving end of the second vertical screw lifting mechanism 54. A first rotary cylinder 56 is mounted below the mounting frame 55. A second rotary cylinder 57 is mounted at the output end of the first rotary cylinder 56. A rotary disk 58 is mounted at the output end of the second rotary cylinder 57. A second finger cylinder 59 is provided below the mounting bracket 55, and a pressing cylinder 510 is provided on both sides of the mounting bracket 55. The specific working method is described as follows: the longitudinal sliding component 52 and the second vertical screw lifting mechanism 54 realize the longitudinal movement and lifting of the clamping mechanism to adapt to clamping workpieces at different positions and ensure the convenience of loading. The first rotary cylinder 56 and the second rotary cylinder 57 are used to drive the second finger cylinder 59 to realize the multi-angle rotation adjustment of the workpiece in the circumferential direction, complete the loading and positioning of the reinforcing steel strip 1c, and then perform welding operations on the workpiece under the operation of the first welding robot 12 to ensure the processing progress.

[0025] To achieve adaptable clamping of the workpiece to be processed, namely the anode steel claw preform 1a, and to ensure the welding process, the first adaptive positioning clamping mechanism 6 includes a housing 61 set inside the worktable 411. A rotating disk 62 is installed inside the housing 61, which can drive the device mounted on it to rotate circumferentially for easy adjustment of the workpiece's welding position and to improve the work process. A hollow rectangular rotating base 63 is installed on the rotating disk 62, and a first sliding bar assembly 64 is installed above the rotating base 63. A first dual-output motor 65 is arranged on the inner side of the rotating base 63. A first lead screw 66 is arranged on both sides of the first dual-output motor 65. A first adjusting frame 67 is arranged above the first lead screw 66. A second slide bar assembly 68 is arranged on both sides of the first adjusting frame 67. A movable seat 69 is arranged on the second slide bar assembly 68. Outer support frames 610 are arranged on both sides of the rotating base 63. A second dual-output motor 611 is arranged between the two outer support frames 610. Both the first dual-output motor 65 and the second dual-output motor 611 are... The purpose of the dual-output shaft motor is to synchronously drive the lead screws located on both sides of it, ensuring convenient operation of the corresponding movements. The second dual-output motor 611 has a second lead screw 612 on each side, and a second adjusting frame 613 on each lead screw 612. A third sliding strip assembly 614 is located on one side of the second adjusting frame 613 and is slidably connected to the moving base 69. A top-pressing cylinder 615 is located above the moving base 69. Specifically, the operation of the first dual-output motor 65 drives the first adjusting frame 67 to translate relative to the rotating base 63, and the operation of the second dual-output motor 611 drives the second adjusting frame 613 to translate relative to the outer support frame 610 and the first adjusting frame 67. The movement and adjustment of these components allow for adjustment of the spacing between different workpieces. Once the position is appropriate, the top-pressing cylinder 615 clamps and positions the delivered workpiece, ensuring the consistency of the workpiece clamping reference and facilitating subsequent welding work, thus improving the work process.

[0026] To ensure the smooth completion of the aluminum-steel direct welding operation, a second welding robot 13, which can be longitudinally moved and adjusted, is installed on one side of the aluminum-steel direct welding assembly 7. This robot is used to perform the aluminum-steel direct welding of the aluminum guide rod 1b to the steel claw beam 1a1, as well as the welding of the reinforcing component to the aluminum guide rod 1b. The aluminum-steel direct welding assembly 7 includes a second gripping and transferring mechanism 71, a second feeding mechanism 72, and a second adaptive positioning and clamping mechanism 73. The material handling and transfer method of the second gripping and transferring mechanism 71 is the same as that of the first gripping and transferring mechanism 41. The workpiece clamping method of the second feeding mechanism 72 is the same as that of the first feeding mechanism 5. The second feeding mechanism 72 can, on the one hand, clamp the externally conveyed aluminum guide rod 1b and place it above the beam 1a1, awaiting the welding operation of the second welding robot 13; on the other hand, it can also pre-weld the stiffener composite plate pre-welding device 8. The welded reinforcing components are clamped and transported to the outer end face of the aluminum guide rod 1b to ensure the continuity of the welding process and improve the work progress. The second adaptive positioning clamping mechanism 73 matches the clamping reference of the first adaptive positioning clamping mechanism 6. The specific working method is as follows: the second gripping and transferring mechanism 71 is used to grip and transfer the reinforced welded workpiece on the closed-loop conveyor line 2 to the second adaptive positioning clamping mechanism 73. The second adaptive positioning clamping mechanism 73 is used to position and clamp the workpiece. The second welding robot 13 is used to perform automated welding of the aluminum guide rod 1b and the anode steel claw beam 1a1. It can also weld the pre-welded reinforcing components to the outside of the aluminum guide rod 1b. After the above welding work is completed, the second gripping and transferring mechanism 71 is also used to send the finished product with all welding processes completed back to the closed-loop conveyor line 2.

[0027] To achieve the welding of aluminum-steel composite plate 1d and stiffening plate 1e, the stiffening plate composite plate pre-welding device 8 includes a U-shaped frame 81. A pre-welding transfer mechanism 9 is installed on the U-shaped frame 81 to weld the aluminum-steel composite plate 1d and stiffening plate 1e into a reinforcing component, and to transfer the reinforcing component to the welding station of the aluminum-steel direct welding assembly device 7. Below the U-shaped frame 81 is a pre-welding bearing mechanism 10 that integrates the function of loading the aluminum-steel composite plate 1d. An interval loading mechanism 11 is installed behind the pre-welding bearing mechanism 10. The pre-welding transfer mechanism 9 includes a longitudinal sliding bar assembly 91 installed above the U-shaped frame 81. A longitudinal transfer frame 92 is installed above the longitudinal sliding bar assembly 91. A third vertical screw lifting mechanism 93 is installed in front of the longitudinal transfer frame 92. The movable end of 93 is equipped with a lifting seat 94. An H-shaped support 95 is located on the front side of the lifting seat 94. A transmission rod 96 is located above the support 95. An electric motor is mounted on one side of the transmission rod 96. Rotating wheels 97 are located on both sides of the transmission rod 96. A rotating rod 98 is located below the support 95. A transmission wheel 99 is located on one side of the rotating rod 98. A synchronous belt is also provided between the rotating wheel 97 and the transmission wheel 99. A carrier plate 910 is located on the inner side below the support 95. A limit plate 911 is located between the two carrier plates 910. A longitudinal slide bar assembly 912 is located above the carrier plate 910. An adjusting cylinder 913 is located on one side of the longitudinal slide bar assembly 912. A moving plate 914 is located above the longitudinal slide bar assembly 912. An installation plate 915 is provided on the inner side of the device, and an L-shaped limiting frame 916 is provided on one side of the installation plate 915. The specific working method is as follows: a pre-welding mechanism (not shown in the figure) is also provided on the rear side of the third vertical screw lifting mechanism 93 in the pre-welding transfer mechanism 9. This mechanism is used to pre-weld the connection between the aluminum-steel composite plate 1d and the stiffener 1e to ensure the stability of the reinforcing component and facilitate subsequent displacement adjustment, thus ensuring the smooth progress of the processing work. In other words, the pre-welding transfer mechanism 9, driven by the longitudinal slide assembly 91 and the third vertical screw lifting mechanism 93, can adjust the position of the device. After the reinforcing component completes the pre-welding work, it is first controlled to move longitudinally, and the inner side of the limiting plate 911 is aligned with the stiffener 1e. The outer end faces are flush, and the position of the limiting frame 916 is adjusted by the operation of the adjusting cylinder 913. When the inner side of the limiting plate 911 contacts and abuts against the outer end face of the rib plate 1e, the adjusting cylinder 913 is controlled to drive the moving plate 914 to move along the longitudinal slide assembly 912, adjusting the position of the limiting frame 916 and aligning its corner with the rib plate 1e to accommodate different specifications of reinforcing components for clamping. Subsequently, in conjunction with the longitudinal movement of the longitudinal slide assembly 91 and the lifting of the third vertical screw lifting mechanism 93, the clamping and transfer of the reinforcing component is completed. After the reinforcing component is removed, in order to ensure that the second feeding mechanism 72 can clamp the workpiece conveniently, the motor is controlled to drive the transmission rod 96 and the rotating wheel 97 to rotate synchronously, utilizing the established synchronous belt.The drive wheel 99 and the rotating rod 98 can rotate together relative to the lower part of the support 95. One end of the rotating rod 98 is fixedly connected to the carrier plate 910, meaning that the carrier plate 910 can rotate with it to adjust the rotation of components such as the limiting plate 911 and the limiting frame 916. In particular, it adjusts the aluminum-steel composite plate 1d in the reinforcing assembly from being below to being horizontal. In this way, the second feeding mechanism 72 can clamp the stiffening plate 1e when clamping it, and the end face of the aluminum-steel composite plate 1d of the reinforcing assembly being fed can correspond to the outer end face of the aluminum guide rod 1b, ensuring the smooth progress of subsequent welding processing.

[0028] To facilitate the loading of the reinforcing aluminum-steel composite plate 1d, the pre-welded support mechanism 10 includes a stand 101. A Z-shaped loading plate 102 is positioned above the stand 101. A pushing cylinder 103 is positioned below the loading plate 102, and a pushing plate 104 is positioned at the output end of the pushing cylinder 103. A lifting cylinder 105 is positioned below the loading plate 102 corresponding to the pushing plate 104, and a lifting plate 106 is positioned at the output end of the lifting cylinder 105. A right-angled trapezoidal material inlet 107 is formed within the loading plate 102, corresponding to the position of the lifting plate 106. Specifically, a feeding groove 107 is provided on the loading plate 102 near the pushing plate 104 for... The aluminum-steel composite panel 1d to be processed is transported to the position corresponding to the pusher plate 104. The pusher cylinder 103 is controlled to run and push it into the placement trough 107. After the intermittent feeding mechanism 11 feeds the stiffener plate 1e at intervals and completes the pre-welding with the aluminum-steel composite panel 1d, the lifting cylinder 105 is controlled to drive the lifting plate 106 to lift the pre-welded reinforcing component in the placement trough 107. Then, the workpiece is clamped by the pre-welding transfer mechanism 9 and transported to the aluminum-steel direct welding assembly 7, waiting for the second feeding mechanism 72 to clamp it to complete the feeding action. This ensures the continuity of production and processing and improves the work process.

[0029] To achieve intermittent feeding of the reinforcing rib 1e, the intermittent feeding mechanism 11 includes a placement plate 111, on which a transverse slide assembly 112 is mounted. A transverse drive cylinder 113 is mounted on one side of the transverse slide assembly 112, and the output end of the transverse drive cylinder 113 is connected to the moving end of the transverse slide assembly 112. A vertical plate 114 is mounted on one side of the placement plate 111, and a wedge-shaped lifting block 115 is mounted above the vertical plate 114. A limiting shell 116 is mounted on one side of the moving end of the transverse slide assembly 112, and a lifting adjustment rod 117 is inserted through the limiting shell 116. A material-pulling plate 118 is mounted on one side above the lifting adjustment rod 117, and a sliding wheel 119 that rolls with the lifting block 115 is rotatably mounted on one side of the lifting adjustment rod 117. The specific working method is as follows: the material plate 102 receives the externally conveyed rib 1e on one side, and the transverse slide assembly 112 is driven by the transverse drive cylinder 113. The lateral movement of the moving end of 2 drives the sliding wheel 119 to roll along the inclined surface of the lifting block 115, thereby driving the lifting adjustment rod 117 to rise and fall vertically. This, in conjunction with the material feeding plate 118, enables the single-workpiece interval feeding of the stiffening plate 1e, ensuring that the feeding rhythm matches the welding rhythm. That is, when the lifting adjustment rod 117 and the sliding wheel 119 move to a position close to the lifting block 115, the material feeding plate 118 is lifted up together and placed above one side of the conveyed stiffening plate 1e. When the external stiffening plate 1e is conveyed, the lateral drive cylinder 113 is controlled to run, causing the material feeding plate 118 to descend and approach the stiffening plate 1e, and convey it to a suitable position above the aluminum-steel composite plate 1d, waiting for the pre-welding work to proceed. After a certain number of stiffening plates 1e are welded, the reinforcing component awaits the subsequent process. It should be further noted that the L-shaped right angle of the conveyed stiffening plate 1e corresponds to the corner of the material plate 102 to ensure the smoothness of the workpiece feeding process.

[0030] The working process of the fully automated aluminum-steel direct welding production line in this embodiment is as follows: S1. Loading operation: The integrated loading and unloading device 3 clamps the anode steel claw preform 1a with the clamping cylinder 35. Through the cooperation between the moving frame 32 and the first vertical screw lifting mechanism 33, the anode steel claw preform 1a is placed on the workpiece rack 23 of the outgoing conveyor belt 21 of the closed-loop conveyor line 2. The outgoing conveyor belt 21 then transports the workpiece to the direction of the crossbeam reinforcing welding device 4.

[0031] S2, Crossbeam Reinforcement Welding: When the workpiece is transported to the crossbeam reinforcement welding device 4, the first gripping and transferring mechanism 41 clamps the workpiece through the first finger cylinder 4112, and transfers the workpiece from the workpiece rack 23 to the first adaptive positioning clamping mechanism 6. The distance between the moving seat 69 is adjusted by the first dual-output motor 65 and the second dual-output motor 611 to match the workpiece specifications. The positioning and clamping of the workpiece is completed by the top pressure cylinder 615. Then, the first feeding mechanism 5 grips the externally transported reinforcing steel strip 1c through the second finger cylinder 59 and transfers it to the welding stations on both sides of the workpiece crossbeam 1a1. Then, the first welding robot 12 is controlled to complete the automated welding of the reinforcing steel strip 1c and the crossbeam 1a1. After the welding is completed, the first gripping and transferring mechanism 41 sends the workpiece back to the workpiece rack 23 of the closed-loop conveyor line 2. After the workpiece is transported to the end by the outgoing conveyor belt 21, it is transferred to the return conveyor belt 22 (not shown in the figure) and transported to the aluminum-steel direct welding assembly device 7.

[0032] S3. Parallel pre-welding operation: During the process of conveying the workpiece along the loop conveyor belt 22, the pre-welding device 8 for the stiffener composite plate is started simultaneously. The aluminum-steel composite plate 1d is received on one side of the pre-welding bearing mechanism 10 and pushed into the material placement trough 107 by the push cylinder 103. The interval feeding mechanism 11 completes the interval feeding of the stiffener 1e through the material feeding plate 118. The pre-welding of the two is completed by the matching welding equipment to form a reinforcing component. Then, the pre-welding transfer mechanism 9 is controlled to run. After the aluminum-steel composite plate 1d and the stiffener 1e are clamped and positioned by the limit frame 916, they are ready to be transferred to the aluminum-steel direct welding assembly device 7 station to achieve parallel processing with the main line process.

[0033] S4. Aluminum-steel direct welding and reinforcement welding: When the workpiece is transported to the aluminum-steel direct welding assembly 7 station, the second gripping and transfer mechanism 71 transfers the workpiece from the workpiece rack 23 to the second adaptive positioning and clamping mechanism 73 to complete the positioning and clamping. The second feeding mechanism 72 clamps the aluminum guide rod 1b and transfers it to the welding station of the workpiece crossbeam 1a1. The second welding robot 13 completes the automated aluminum-steel direct welding between the aluminum guide rod 1b and the anode steel claw crossbeam 1a1. After the aluminum guide rod 1b is welded, the pre-welding transfer mechanism 9 transfers the pre-welded reinforcement component to the outer welding station of the aluminum guide rod 1b. The second welding robot 13 completes the welding operation between the reinforcement component and the aluminum guide rod 1b.

[0034] S5. Unloading Operation: After the welding of the entire process is completed, the second gripping and transferring mechanism 71 sends the finished workpiece back to the workpiece rack 23 of the closed-loop conveyor line 2. The workpiece is transported to the beginning and end connection end by the return conveyor belt 22. The integrated loading and unloading device 3 removes the finished workpiece from the workpiece rack 23 to complete the unloading operation. Thus, the fully automated welding process of the anode guide rod group 1 is completed.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
