Description

Technical Field

[0001] The invention relates to the technical field of liquid flow battery production, in particular to a production device for an electrode frame and an ion exchange membrane integrated structure. Background Art

[0002] The liquid flow battery system is a low-cost, high-efficiency, environmentally friendly liquid flow energy storage battery with the advantages of high energy density and current efficiency, simple and easy to operate device, long service life, and low cost. The liquid flow battery stack is the core component of the liquid flow battery system. It is the place where the redox reaction occurs in the battery system to achieve energy conversion and storage. The working principle of the liquid flow battery is based on electrochemical reactions. Its main feature is that the energy storage medium (electrolyte solution) and the active substances that react are stored separately and transported to the battery stack through a circulation pump to participate in the electrochemical reaction.

[0003] In the related art, a flow battery stack is usually formed by stacking multiple flow batteries in series, and a single flow battery includes an electrode frame, an ion exchange membrane, a current collecting plate, an electrode, etc. When the several are assembled, the ion exchange membrane is fixed to the electrode frame through a membrane pressing frame, and a sealing groove is set between the ion exchange membrane and the electrode frame for sealing, and the electrode is assembled in the electrode frame.

[0004] During the battery stacking process, the back membrane of the cut ion exchange membrane needs to be manually peeled off. However, the back membrane is firmly bonded to the ion exchange membrane, and the efficiency of manual peeling of the ion exchange membrane is low. In addition, during the peeling process, the workers' hands may carry a lot of stains and dust, which can easily contaminate the surface of the ion exchange membrane and cause the ion exchange membrane to fail. The ion exchange membrane will also have sticky wrinkles due to uneven force, reducing the durability of the ion exchange membrane.

[0005] In patent application CN2024112507345, a device for bonding an ion exchange membrane to an electrode frame on one side has been disclosed, which realizes the automated peeling and bonding of the ion exchange membrane to the electrode frame on one side. However, after the ion exchange membrane is bonded to the electrode frame on one side, how to connect it to the electrode frame on the other side requires further improvement of the device to further improve the level of automation.

[0026] Compared with the prior art, the present invention has the following advantages:

[0027] 1. The above-mentioned electrode frame and ion exchange membrane integrated structure production device is used for automatically bonding ion exchange membranes and electrode frames in liquid flow battery stacks. The membrane material is output from the membrane material unfolding assembly, first cut by the cutting assembly, and then tensioned by the tensioning assembly. The pressing assembly presses the ion exchange membrane on the membrane material onto the first electrode frame of the bonding platform. Finally, the robotic arm clamps the second electrode frame and places it on the ion exchange membrane. The hot pressing assembly heats and presses the first electrode frame, the ion exchange membrane and the second electrode frame as a whole to form an integrated structure of the electrode frame and the ion exchange membrane. Since the first electrode frame is provided with a glue layer, the ion exchange membrane is separated from the back membrane and bonded to the electrode frame, thereby realizing automatic bonding of the ion exchange membrane and the first electrode frame. At the same time, the robotic arm and the hot pressing assembly realize automatic bonding of the second electrode frame and the ion exchange membrane. No manual operation is required throughout the process, thereby avoiding the contamination of the ion exchange membrane and uneven force during manual operation, and effectively improving the bonding efficiency and bonding quality of the ion exchange membrane.

[0028] 2. A first positioning column is provided on the bonding platform, and the first positioning column can cooperate with the first positioning protrusion and the second positioning protrusion on the first electrode frame and the second electrode frame, which can not only fix the first electrode frame on the bonding platform to prevent the first electrode frame from moving on the bonding platform and affecting the bonding of the ion exchange membrane, but also align the first electrode frame and the second electrode frame to avoid bonding errors.

[0029] 3. Furthermore, a second positioning column is provided on the hot pressing plate to position and fix the electrode frame and the ion exchange membrane integrated structure to prevent the electrode frame and the ion exchange membrane integrated structure from moving away from the heating and pressing position during the heating and pressing process. At the same time, an elastic member is provided between the second positioning column and the hot pressing plate to avoid interference with the fit between the hot pressing plate and the hot pressing platform during the pressing process.

[0030] 4. The electrode frame and ion exchange membrane integrated structure production device is provided with a tensioning roller to support the width direction of the membrane material, and a tensioning drive is provided to drive the tensioning roller to rotate around its axis, so that the tensioning roller can drive the membrane material to move along its length direction, thereby continuously approaching the pressing assembly. Therefore, the tensioning roller can tension the membrane material in the entire length direction, and the tensioning drive can drive the tensioned membrane material to move, effectively taking into account the tensioning and movement of the membrane material, avoiding wrinkles in the membrane material movement process, and ensuring the high efficiency of the membrane material movement.

[0031] 5. At the same time, the tensioning assembly is also provided with a tensioning roller bracket to support the tensioning roller. Since the tensioning roller bracket is movably connected to the bonding platform, the tensioning roller bracket can move in the direction of movement of the film material and can move in the direction close to or away from the bonding platform. Therefore, the tensioning roller bracket can drive the tensioning roller to move in the direction of movement of the film material and in the direction close to or away from the bonding platform, respectively, to adjust the horizontal distance and tensioning angle between the tensioning roller and the laminating assembly, thereby improving the flexibility of the use of the tensioning assembly.

[0032] 6. The production device of the integrated structure of the electrode frame and the ion exchange membrane adopts a pressing roller to press the wide edge of the membrane material. As the membrane material moves, the pressing roller presses the ion exchange membrane in sequence along the length direction of the ion exchange membrane, so that the entire ion exchange membrane is in contact with the adhesive layer of the electrode frame, and finally the ion exchange membrane and the electrode frame are bonded. During the whole process, the membrane material moves around the pressing roller to avoid wrinkles on the ion exchange membrane. Furthermore, the pressing roller bracket can also drive the pressing roller to move in a direction close to or away from the bonding platform, so as to adapt to electrode frames of different thicknesses and facilitate the placement and removal of the electrode frames.

[0033] 7. The laminating platform is also provided with a membrane material limiter, which can simultaneously limit the width position of the membrane material, thereby preventing the membrane material from moving in width during movement, causing deviation in the laminating position of the ion exchange membrane and the electrode frame, and effectively improving the accuracy of the laminating position.

[0034] 8. The laminating platform is equipped with vacuum air holes and negative pressure air sources, which fix the electrode frame on the laminating platform through vacuum adsorption to prevent the electrode frame from moving on the platform. In addition, the laminating platform is also equipped with heating elements evenly distributed along the length direction, which is conducive to uniform heating and activation of the hot melt adhesive layer on the electrode frame, so that the ion exchange membrane can be quickly bonded to the electrode frame, improving the laminating speed and quality.
