Description
Technical Field
[0001] This utility model belongs to the field of green hydrogen production technology, specifically relating to a device for flipping electrode plates. Background Technology
[0002] Hydrogen energy, as a clean and renewable energy source, is one of the ideal energy sources for sustainable development. Developing hydrogen energy is a key direction of strategic emerging industries. Hydrogen energy has a wide range of applications, enabling large-scale peak shaving of the power grid and cross-seasonal and cross-regional energy storage, and accelerating the decarbonization of industries, buildings, transportation and other fields.
[0003] The alkaline water electrolysis hydrogen production unit consists of an electrolyzer and an auxiliary system. The core components of the alkaline electrolyzer mainly include electrode plates, coated nickel mesh, diaphragm cloth, gaskets, and fasteners. Among these, the electrode plates are one of the most critical core components. As a supporting component of the electrolyzer structure, the electrode plates mainly support the hydrogen and oxygen side electrodes and the electrolysis diaphragm cloth in each individual electrolysis chamber, and provide hydrogen, oxygen, and alkali solution channels to separate the hydrogen produced at the cathode and the oxygen produced at the anode in each chamber, ensuring the safe operation of the electrolyzer. Before final assembly, the front and back sides of the hydrogen, oxygen, and alkali solution channels on the electrode plates need to be pressed and pasted together. Traditionally, electrode plate flipping and pasting are done manually, which is time-consuming and labor-intensive, increasing the production cost of the electrolyzer equipment and, to some extent, limiting the development of hydrogen energy.
[0004] With the rapid development of the hydrogen energy industry, the gas production and volume of individual electrolyzers are getting larger and larger. As a result, the number of cells in a single electrolyzer is also increasing. The traditional manual method of turning and pressing the front and back of the cells together is no longer applicable. Utility Model Content
[0005] The purpose of this invention is to provide an automated device for flipping the electrode plates of an electrolytic cell, in order to solve the problems of existing equipment for mass production of electrolytic cells.
[0006] The technical solution of this utility model is: an automated device for flipping the electrode plates of an electrolytic cell, comprising: a feeding robot, a feeding fixture, a feeding conveyor, a folding ramp feeding conveyor, a flipping machine, a folding ramp unloading conveyor, an unloading conveyor, an unloading robot, and an unloading fixture.
[0007] The loading robot and loading fixture grab and transfer the electrode plates to the loading conveyor. The electrode plates are then transported via the loading conveyor and the folding ramp loading conveyor to the flipping machine. After flipping, they are transported via the folding ramp unloading conveyor and the unloading conveyor, where the unloading robot and unloading fixture grab and transfer the electrode plates. The entire process is controlled by a control cabinet. The control cabinet uses control signals to control the automatic electrode plate flipping production line, enabling automatic loading, unloading, and flipping of the electrode plates. This allows for batch preparation of electrode plates for the electrolytic cell. An emergency stop button is also provided in the control cabinet to prevent mechanical and personal accidents.
[0008] Based on the above solution, the further addition of the loading fixture includes: a loading fixture truss; four sets of support plates evenly distributed on the loading fixture truss, with a rectangular groove in the middle of each support plate; a slider on the movable electromagnet that cooperates with the groove of the support plate, and the slider is used to fix the robot to the support plate; the loading robot is connected to the loading fixture through a clamp. The rectangular groove on the support plate and the slider on the movable electromagnet cooperate to enable the gripping of multiple types of electrode plates, improving the compatibility of the production line.
[0009] The structure of the unloading fixture is the same as that of the loading fixture, and the unloading robot is connected to the unloading fixture through a clamp.
[0010] Based on the above scheme, furthermore, the rollers of the feeding conveyor are connected to the servo motor of the feeding conveyor via a chain to complete the torque transmission of the servo motor of the feeding conveyor, and the transportation is realized by the rotation of the rollers of the feeding conveyor.
[0011] Based on the above scheme, furthermore, the servo motor of the feeding conveyor is connected to the roller of the feeding conveyor via a chain to complete the torque transmission of the servo motor of the feeding conveyor, and the transportation is realized under the rotation of the roller of the feeding conveyor.
[0012] Building upon the aforementioned solution, the rollers of the folding ramp conveyor are further connected to the servo motor via chains, enabling torque transmission and transport through the rotation of the rollers. Folding ramps are located on both sides of the conveyor. The control box controls the switching between electrode waiting and release states, as well as the folding and extending states of the ramps, to accommodate the pressing and bonding of electrodes of various sizes and diameters. When the electrode size is small, the ramps can be folded downwards, allowing workers to stand on either side for easier pressing and bonding.
[0013] The servo motor of the folding ramp unloading conveyor is connected to the rollers of the folding ramp unloading conveyor via a chain, completing the torque transmission of the servo motor. The rotation of the rollers enables transportation. Folding ramps are located on both sides of the folding ramp unloading conveyor. The control box of the folding ramp unloading conveyor uses control signals to switch between the waiting and releasing states of the unloading plates, as well as the folding and extending states of the folding ramps, to accommodate the pressing and bonding of plates of various sizes and diameters. Similarly, when the plates being processed are small, the folding ramps can be folded downwards, allowing workers to stand on both sides of the folding ramps for convenient pressing and bonding operations.
[0014] Based on the above scheme, furthermore, the servo motor I of the flipping machine is connected to the flipping machine truss via a belt to complete the torque transmission of the servo motor I and realize the forward and reverse flipping; the flipping machine roller has a double-layer roller, which is connected to the servo motor II of the flipping machine via a chain to complete the torque transmission of the servo motor II, and the transportation is realized by the rotation of the flipping machine roller.
[0015] The electrode plates are transported to the interlayer of the flipping machine rollers via the folding ramp feeding conveyor, where they are clamped by a clamping device. Then, the flipping machine truss rotates 180° to complete the front and back flipping. After that, the clamping device is released, and the electrode plates are transported to the folding ramp unloading conveyor via the flipping machine rollers.
[0016] Based on the above scheme, the electrode plates are further placed on the electrode plate tray during loading and on the unloading electrode plate tray during unloading. One or two unloading electrode plate trays are set up. Through the handling of the unloading robot and the gripping of the unloading fixture, the electrode plates are automatically classified and unloaded, and different electrode plates are classified and placed on different unloading electrode plate trays to complete the classification and placement of different types of electrode plates.
[0017] Based on the above scheme, the folding ramp loading conveyor and the folding ramp unloading conveyor are further equipped with guiding devices to center the transported plates.

[0020] (2) In this utility model, the automatic loading and unloading of electrode plates is achieved under the control of the control cabinet through the handling of robots and the gripping of tooling, thereby improving production efficiency. The tooling can also grip multiple types of electrode plates.
[0021] (3) The extension and folding of the loading and unloading machine ramp in this utility model can be switched to adapt to the pressing and pasting of multiple models of electrode plates with different diameters, which increases the operability of manual pasting and pressing.
