Description

Technical Field

[0001] This invention belongs to the technical field of assembly tooling production lines for the alkaline water electrolysis hydrogen production industry. The invention relates to an electrolyzer assembly production line and its usage method. Background Technology

[0002] The electrolyzer is the core component of the alkaline water hydrogen production process. According to Faraday's first and second laws, alkaline water is electrolyzed in the electrode frames within the electrolyzer to produce hydrogen and oxygen. The electrolyzer consists of positive and negative reaction plates, hundreds of electrode frames, hundreds of sealing components, and hundreds of installation accessories. Its structure is extremely compact, and its weight can reach up to sixty tons.

[0003] The traditional assembly process for electrolytic cells involves vertical assembly from bottom to top, done manually in one go. After assembly, the product needs to be left to stand for a week to release the stress on the tension bolts before being lifted away and rotated by an industrial gantry crane in the factory. Electrolytic cells can be up to six meters long, meaning workers must use a six-meter lift to assemble the product. This lift carries not only workers but also tons of loose parts, making the process extremely dangerous. Furthermore, because the assembled product cannot be immediately lifted away by the gantry crane, only one electrolytic cell can be installed on a single workbench at a time, resulting in extremely low work efficiency. Summary of the Invention

[0004] To overcome the shortcomings of the existing technology, the present invention provides an electrolytic cell assembly production line and its usage method. Workers no longer need to use high-altitude elevators for assembly. The assembly line-style assembly greatly reduces the error rate during the installation process. The existence of buffer positions allows this assembly line to continuously assemble products, eliminating the reduction in production efficiency due to excessive product resting time.

[0005] The above-mentioned objective of this invention is achieved through the following technical solution:

[0006] An electrolytic cell assembly production line includes an assembly group, a buffer group, and a turning group. The assembly group includes several workstations, with a height difference of less than 1.2m between any two adjacent workstations. Each workstation is equipped with an industrial transfer vehicle and an industrial hydraulic thruster. Except for the last workstation, each of the remaining workstations has auxiliary workstations and pole frame workstations of corresponding heights on both sides. Except for the last workstation, all other workstations are equipped with industrial gantry robots. The last workstation does not have a top frame, and its upper sides are equipped with manual workstations for human movement, with pull-out drawers on the manual workstations. A buffer group for parking workpieces is located at the end of the assembly group. The buffer group includes buffer workstations for placing several industrial transfer vehicles. A turning group is located at the end of the buffer group and includes an industrial turning machine placed in a groove on the bottom surface. The front end of the assembly group is also equipped with an industrial hydraulic thruster and an industrial transfer vehicle.

[0007] Furthermore, the workstation racks, auxiliary workstation racks, and pole frame workstation racks are all made of steel and are welded frames. Also, in any two adjacent workstation racks, the workstation rack in front is lower in height than the workstation rack behind it.

[0008] Furthermore, each industrial hydraulic thruster is equipped with a corresponding moving track for propelling the industrial transport vehicle. The industrial hydraulic thruster includes a hydraulic cylinder, the output end of which is connected to a propulsion hook. The bottom of the propulsion hook is equipped with rollers, which move and propel the vehicle on the track groove.

[0009] Furthermore, the pull plate is connected to the manual workstation plate via a slider and linear guide rail, enabling it to be pulled out. When manual movement is required for installation, the pull plate fills the gap in the manual workstation plate. After installation is completed, the pull plate returns to its original position, allowing the industrial transfer cart to move the workpiece to the buffer group.

[0010] Furthermore, the auxiliary workstation frame is equipped with steps for personnel to move around.

[0011] Furthermore, industrial transfer vehicles can be connected to the ground via industrial rails or placed directly on the ground for use.

[0012] Furthermore, the workpiece surface of the industrial tilting machine is located on the same plane as the ground.

[0013] The industrial hydraulic thrusters, industrial transfer vehicles, industrial gantry robots, and industrial tilting machines mentioned are all commercially available products. There are no restrictions on any single model; as long as their working functions are realized, they are acceptable.

[0014] The above-mentioned electrolytic cell assembly production line is used as follows: The electrolytic cell segmented assembly line is a semi-automatic assembly line. It consists of a multi-station assembly line, with each station equipped with a fixed quantity and height of workstation frame. Workers stand on fixed auxiliary workstation frames and electrode frame welding frames to work. Each assembly station is equipped with an independent assisted handling industrial gantry robot. Workers use the industrial gantry robot to move the products and then perform manual assembly. The assembled workpieces are transported by industrial transfer vehicles to the next workstation frame for assembly until the last workstation frame is assembled. After the last workstation frame is assembled, the industrial transfer vehicle transfers the products to a buffer station for resting for one week. After resting, the gantry crane (factory building component, not related to the structure of this invention) finally lifts the workpieces one by one onto the corresponding industrial flipping machine for flipping at a 90-degree angle.

[0015] The beneficial effects of this invention compared to the prior art are:

[0016] The present invention provides an electrolytic cell assembly production line and its usage method. Workers no longer need to use high-altitude elevators for assembly. The assembly line-style assembly greatly reduces the error rate during the installation process. The existence of buffer positions allows the assembly line to continuously assemble products, eliminating the reduction in production efficiency due to excessive product resting time.

[0028] The present invention is described in detail below through specific embodiments, but this does not limit the scope of protection of the present invention. Unless otherwise specified, the experimental methods used in the present invention are all conventional methods, and the experimental equipment, materials, reagents, etc. used can all be obtained commercially. The number of workstations can be set as needed according to the workpiece requirements. Example

[0029] An electrolytic cell assembly production line; such as Figures 1-9 As shown, the assembly group includes an assembly group, a buffer group, and a flipping group. The assembly group includes several workstations, with a height difference of less than 1.2m between any two adjacent workstations. Each workstation is equipped with an industrial transfer cart 2 and an industrial hydraulic thruster 1. Except for the last workstation, each of the remaining workstations has auxiliary workstations 9 and extreme frame workstations 11 of corresponding height on both sides. Except for the last workstation, all other workstations are equipped with industrial gantry robots 8. The last workstation does not have a top frame, and its upper sides are equipped with manual workstations 12 for human movement. The manual workstations 12 have pull-out drawers 13. A buffer group for parking workpieces is located at the end of the assembly group. The buffer group includes buffer workstations for placing several industrial transfer carts 2. A flipping group is located at the end of the buffer group and includes an industrial flipping machine 14, which is placed in a groove on the bottom surface. An industrial hydraulic thruster 1 and an industrial transfer cart 2 are also separately provided at the front end of the assembly group.

[0030] The workstation frame, auxiliary workstation frame 9, and extreme frame workstation frame 11 are made of steel and are welded frames. Furthermore, in any two adjacent workstation frames, the workstation frame in front is lower in height than the workstation frame behind it.

[0031] Each industrial hydraulic thruster 1 is equipped with a corresponding moving track for propelling the industrial transport vehicle 2. The industrial hydraulic thruster 1 includes a hydraulic cylinder 17, the output end of which is connected to a propulsion hook 18. The bottom of the propulsion hook 18 is provided with a roller 19, which moves and propels the vehicle on the track groove 16 of the moving track.

[0032] The pull plate 13 is connected to the manual workstation plate 12 via a slider and a linear guide rail, enabling it to be pulled out. When manual movement is required for installation, the pull plate 13 fills the gap in the manual workstation plate 12. After installation is completed, the pull plate 13 is pulled back to its original position, allowing the industrial transfer cart 2 to move the workpiece 10 to the buffer group.

[0033] The auxiliary workstation frame 9 is equipped with steps for personnel to move around.

[0034] The industrial transfer vehicle 2 can be connected to the ground 15 via industrial rails, or it can be placed directly on the ground 15 for use.

[0035] The workpiece surface of the industrial tilting machine 14 is on the same plane as the ground 15.

[0036] The industrial hydraulic thruster 1, industrial transfer vehicle 2, industrial gantry robot 8, and industrial tilting machine 14 are all commercially available products. There is no restriction on any single model; as long as their working functions are realized, they are acceptable.

[0037] The production line is also equipped with a PLC control system. The industrial hydraulic thruster 1, industrial gantry robot 8, and industrial tilting machine 14 are connected to the PLC control system respectively, and there is no restriction on the specific model, as long as their working functions are realized.

[0038] The above-mentioned electrolytic cell assembly production line is used as follows: The electrolytic cell segmented assembly line is a semi-automatic assembly line.

[0039] The industrial hydraulic thruster 1 is hydraulically powered, with a hydraulic cylinder 17 driving a thrust hook 18 with rollers 19 to move back and forth in the track groove 16. One industrial hydraulic thruster 1 is located under each workstation. Each workstation and its corresponding auxiliary workstation 9 are directly mounted on the ground 15. The height of each workstation is set by the manufacturer according to the height dimensions of their product. To facilitate worker installation, the height difference between any two adjacent workstations is preferably no more than 1.2m. An industrial gantry robot 8 is equipped on each workstation (except the last workstation). The height of the mounting frame varies for each corresponding workstation, resulting in different heights for each workstation and their corresponding auxiliary workstation 9. An empty industrial transfer cart 2 is transported by an industrial hydraulic propeller 1 to the location of the first workstation rack. Workers on the first workstation rack and its corresponding auxiliary workstation rack 9 assemble the workpiece to a certain height. After assembly, the industrial hydraulic propeller 1 pushes the industrial transfer cart 2, carrying the workpiece, to the next workstation rack for further assembly at a certain height, and so on. After manual assembly is completed at the last workstation rack, the industrial hydraulic propeller 1 transports the final workpiece's industrial transfer cart 2 to a buffer station for resting. (One set of industrial hydraulic propellers and industrial transfer carts is configured under each workstation to facilitate the movement and transportation of the corresponding workstation's industrial transfer cart for uninterrupted production on the assembly line.) The rested workpiece is lifted by an industrial crane in the factory to an industrial tilting machine 14. The industrial tilting machine 14 tilts the electrolytic cell workpiece 10. The specifications of the industrial tilting machine 14 are selected by the manufacturer according to the weight range of their products, and the tilting angle is 90 degrees. Finally, the workpiece is loaded onto a vehicle or stored in a warehouse, completing the assembly process of workpiece 10. The remaining industrial transfer vehicle 2 is then lifted by an industrial crane in the factory to the initial end of the assembly group or buffer station to restart the workpiece assembly process.

[0040] The embodiments described above are merely preferred embodiments of the present invention, and not all feasible embodiments of the present invention. Any obvious modifications made by those skilled in the art without departing from the principles and spirit of the present invention should be considered to be included within the scope of protection of the claims of the present invention.
