[0023] When the emergency stop button is in the open state, the control unit controls the drive unit to stop driving the guide roller group;

[0024] When the emergency stop button is in the off state, the control unit controls the drive unit to work normally.

[0025] In one embodiment, the feeding assembly further includes a feeding rack and a roll for winding the film.

[0046] The flow battery stack is the core component of a flow battery system. Its basic working principle is to convert chemical energy into electrical energy through the flow of electrolyte. Flow battery stacks are widely used in large-scale energy storage applications and are characterized by high safety, long lifespan, and high efficiency.

[0047] The exchange membrane, also known as the ion-conducting membrane, is one of the core components of a flow battery stack. Its main function is to isolate the active materials in the positive and negative electrode electrolytes, preventing them from directly contacting and reacting chemically, while allowing specific ions (such as hydrogen ions and sodium ions) to pass through, forming a closed circuit in the battery. The performance of the exchange membrane directly affects the efficiency, lifespan, and cost of the flow battery stack.

[0048] As a key component of flow battery stacks, the exchange membrane has received widespread attention and research in recent years. However, in actual production and assembly, it is usually necessary to cut the rolled exchange membrane. Cutting the exchange membrane requires extremely high precision to ensure that the size and shape of the membrane meet the design requirements of the flow battery stack. Typically, the dimensional error of the cut needs to be controlled within millimeters to ensure the compatibility of the membrane with other components such as electrodes and bipolar plates. Furthermore, in mass production, it is necessary to ensure the consistency of the size, thickness, and quality of each cut membrane to ensure the stability and reliability of the battery performance. In related technologies, manual cutting often makes it difficult to detect whether the cut exchange membrane size meets the requirements. It is difficult to identify defective products with insufficient dimensions, which can easily lead to major quality problems such as electrolyte leakage when assembling the battery stack. Moreover, the cutting efficiency is low, resulting in low final product efficiency.

[0049] Based on this, an exchange membrane cutting device is provided, which has better cutting and inspection accuracy, high yield, and high cutting efficiency.

[0050] See Figure 1 As shown, the exchange membrane cutting device 10 provided in this application includes a feeding assembly 100, a cutting assembly, and a discharging assembly 300. The feeding assembly 100 is used to feed the material membrane to the cutting station B. The cutting assembly is located on one side of the feeding assembly 100 and at the cutting station B. The cutting assembly includes a cutting blade 200, which is used to cut the material membrane located at the cutting station B. The discharging assembly 300 is located on the side of the cutting assembly away from the feeding assembly 100. The discharging assembly 300 includes a support plate 310 and a negative pressure adsorption element. The support plate 310 includes a support surface for supporting the cut semi-finished membrane. The support surface is provided with a plurality of adsorption holes 320, which are connected to the negative pressure adsorption element. The support surface is provided with a plurality of scales, which are arranged along the direction from the feeding station to the cutting station.

[0051] It is understood that after the feeding component 100 feeds the film to the film cutting station B, the cutting component cuts the film at the film cutting station B to form a semi-finished film. The semi-finished film is received by the support plate 310 of the unloading component 300 for unloading. After the support plate 310 receives the cut semi-finished film, the adsorption holes 320 on the support plate 310 of the unloading component 300, which are connected to the negative pressure adsorption component, can adsorb the semi-finished film on the support surface of the support plate 310, thereby facilitating the flattening and adsorption and fixation of the semi-finished film on the support plate 310. The size of the semi-finished film is then detected by the scale on the support surface. If it meets the size requirements, the semi-finished film is determined to be a finished film and can be manually placed into the finished product box. If it does not meet the size requirements, the semi-finished film can be manually placed into the waste box.

[0052] The exchange membrane cutting device 10 of this application realizes automatic cutting of the material membrane through the feeding component 100, the cutting component and the unloading component 300. While improving the cutting efficiency, the setting of the carrier plate and the adsorption hole 320 of the unloading component 300 helps to improve the convenience of detecting whether the semi-finished membrane after cutting meets the size requirements, improves the detection accuracy, and also helps to improve the size accuracy of the final finished membrane, improve the yield, and benefit the efficiency and life of the battery stack that uses the finished membrane.

[0053] In some embodiments, a plurality of adsorption holes 320 are arranged around the periphery of the bearing surface. This is beneficial to improving the flatness of the semi-finished membrane adsorbed on the bearing surface, and thus improving the accuracy of the detection of the semi-finished membrane.

[0054] In some embodiments, such as Figure 1 As shown, the feeding assembly 100 includes a guide roller group 110 and a drive member 120. The guide roller group 110 is used to allow the film to pass around the guide roller group 110, and the drive member 120 is driveably connected to the guide roller group 110. The guide roller group 110 is configured to move the film from the feeding station A toward the film cutting station B under the drive of the drive member 120. In this way, the film located at the feeding station A is moved to the film cutting station B so that the film cutting blade 200 located at the film cutting station B can cut the film.

[0055] In some embodiments, see Figure 2 and Figure 3 As shown, Figure 2 This is a cross-sectional view of the exchange membrane cutting device 10 in one embodiment of this application. Figure 3This is a schematic diagram of the structure of the film covering the guide roller assembly 110 in one embodiment of this application. The guide roller assembly 110 includes a first roller shaft 111, a second roller shaft 112, a third roller shaft 113, and a fourth roller shaft 114. The first roller shaft 111 and the second roller shaft 112 are adjacent and rotate towards each other to form a first roller assembly, with a portion of the film located between the first roller shaft 111 and the second roller shaft 112. The third roller shaft 113 and the fourth roller shaft 114 are adjacent and rotate towards each other to form a second roller assembly. The second roller assembly is located on the side of the first roller assembly near the cutter assembly, with the remaining portion of the film located between the third roller shaft 113 and the fourth roller shaft 114. Alternatively, the guide roller assembly 110 is used to allow the film to pass sequentially between the first roller shaft 111 and the second roller shaft 112, and between the third roller shaft 113 and the fourth roller shaft 114. The film moves from the first roller group towards the second roller group. When the film reaches the first roller group, it is sandwiched between the first roller shaft 111 and the second roller shaft 112, which helps to keep the film in an unfolded state and maintain its flatness. When the film reaches the second roller group, it is sandwiched between the third roller shaft 113 and the fourth roller shaft 114, which helps to further unfold the film and maintain its flatness. The arrangement of the first and second roller groups provides double protection, which helps to keep the film in a flat and unfolded state, facilitates accurate cutting by the film cutter 200, and thus helps to improve the yield of the exchange membrane cutting device 10.

[0056] In some embodiments, see Figure 1 , Figure 2 and Figure 3 As shown, the guide roller group 110 also includes at least one auxiliary roller shaft 115, which is disposed between the first roller group and the second roller group. The first roller shaft 111 and the second roller shaft 112 are adjacent along a first direction F1, and the rotation directions of the first roller shaft 111 and the second roller shaft 112 are opposite. The third roller shaft 113 and the fourth roller shaft 114 are adjacent along a second direction F2, and the rotation directions of the third roller shaft 113 and the fourth roller shaft are opposite. Along the direction from the feeding station to the film cutting station, the auxiliary roller shaft 115 is disposed between the second roller shaft 112 and the third roller shaft 113. The first direction F1 and the second direction F2 intersect each other with the direction from the feeding station to the film cutting station.

[0057] The auxiliary roller 115 is designed to improve the traction and guidance of the film, facilitate the smooth transfer of the film, reduce the tearing damage to the film, and further improve the yield rate, or in other words, improve the quality of the finished film obtained from cutting.

[0058] In some embodiments, such as Figure 1 and Figure 2As shown, the exchange membrane cutting device 10 also includes a control unit 400, which is electrically connected to the drive unit 120. The control unit 400 is configured to control the drive unit 120 to switch between a working state and a paused state. If the drive unit 120 is controlled to be in the working state by the control unit 400, the drive unit 120 drives the guide roller group 110 to move the material film towards the film cutting station B. After the material film moves to a preset position and extends a preset length, the control unit 400 controls the drive unit 120 to be in the paused state. At this time, the drive unit 120 stops driving the guide roller group 110. Then, the control unit 400 drives the film cutting blade 200 to cut the material film to form the cut material film, i.e., the semi-finished film. The adsorption hole 320 then adsorbs the semi-finished film, and the size of the semi-finished film is detected by the scale on the bearing surface. If the size requirement is met, the semi-finished film is determined to be a finished film and can be manually placed into the finished product box. If the size requirement is not met, the semi-finished film can be manually placed into the waste box.

[0059] In this embodiment, the single working time of the drive unit 120 can be controlled by the control unit 400. By controlling the working time of the drive unit 120, the length of the film extension can be controlled, thereby controlling the size of the semi-finished film formed by cutting the film. Alternatively, the drive unit 120 can be understood as a motor, in which case the control unit 400 can control the number of rotations of the motor in a single operation, thereby controlling the length of the film extension driven by the guide roller group 110, and thus controlling the size of the semi-finished film formed by cutting the film. After cutting the film and detecting whether the size of the cut semi-finished film meets the requirements, the control unit 400 controls the drive unit 120 to enter the next working state. In this way, through the above-mentioned control of the drive unit 120 and the film cutting blade 200 by the control unit 400, it is possible to control the cutting of semi-finished films with precise dimensions, which is beneficial to improving the yield.

[0060] In some embodiments, the controller is provided with a control screen, which can be used to select the control element 400 to control the single working time of the drive element 120, or to select the control element 400 to control the number of rotations of the drive element 120 in a single working cycle, so as to cut semi-finished films of different sizes.

[0061] In this embodiment, the membrane cutting blade 200 can be used for longitudinal or transverse membrane cutting, and can be adjusted according to actual needs to improve the setting freedom of the exchange membrane cutting device 10 of this application. No further restrictions are imposed here.

[0062] In some embodiments, such as Figure 1As shown, the exchange membrane cutting device 10 also includes an emergency stop button 500, which is electrically connected to the control unit 400. The emergency stop button 500 is configured to switch between an on and off state. When the emergency stop button 500 is in the on state, the control unit 400 controls the drive unit 120 to stop driving. When the emergency stop button 500 is in the off state, the control unit 400 controls the drive unit 120 to operate normally. It should be noted that the on and off states of the emergency stop button 500 are distinct from the working and paused states of the drive unit. Thus, in the event of an emergency, the control unit 400 can control the drive unit 120 to stop driving immediately, improving the operational safety of the exchange membrane cutting device 10.

[0063] In some embodiments, continue reading Figure 1 As shown, the exchange membrane cutting device 10 also includes an activation button 600, which is electrically connected to the control unit 400 so that the control unit 400 can be controlled to operate. The activation button 600 is the overall control button.

[0064] In some embodiments, such as Figure 1 and Figure 2 As shown, the feeding assembly 100 also includes a feeding rack 130 and a roll of film 140. The feeding rack 130 is located on the side of the guide roller assembly 110 away from the cutter assembly and is located at feeding station A. The roll of film 140 is placed on the feeding rack 130 and is used to release the film onto the guide roller assembly 110. In this way, multiple rolls of film 140 can be set up. After the film on the previous roll of film 140 is used up, a new roll of film 140 can be placed on the feeding rack, which is convenient to use and helps to improve film cutting efficiency.

[0065] In some embodiments, such as Figure 1 and Figure 2 The feeding assembly 100 also includes a guide roller 150, which is located between the feeding frame 130 and the guide roller group 110. A portion of the film is wound around the guide roller 150, which is used to traction the film. The guide roller 150 has two ends arranged opposite each other along its axial direction, and a middle section located between the two ends. The radial dimension of the guide roller 150 gradually increases from the middle section towards the ends. That is, the guide roller 150 has a conical shape with a large radial dimension in the middle and small radial dimensions at both ends, which is beneficial for guiding the film, keeping it in the middle position, reducing the risk of film deviation, facilitating the normal operation of the film cutting process, and improving the yield and cutting efficiency.

[0066] In some embodiments, the feeding assembly 100 further includes a traction roller 160 and a detector 170. The traction roller 160 is disposed between the feeding frame 130 and the guide roller 150, and a portion of the film is wound around the traction roller 160. The detector 170 is disposed on the traction roller 160 and electrically connected to the control unit 400. The detector 170 is used to detect whether the traction roller 160 is covered with film. The traction roller 160 pulls the film, which helps to further unfold and flatten the film. At the same time, the detector 170 on it helps to detect in a timely manner whether the film is being fed normally, thus improving the working stability of the exchange membrane cutting device 10.

[0067] In this embodiment, an alarm can also be set up. The alarm is electrically connected to the controller and the detector 170. When the detector 170 detects that the traction roller 160 is not covered with a film and the controller controls the drive unit 120 to be in working state, the alarm can sound an alarm to alert the staff, so that the staff can adjust the exchange membrane cutting device 10 in time to make it work normally.

[0068] The exchange membrane cutting device 10 of this application uses a feeding assembly 100 to precisely feed the membrane, ensuring the membrane extends to a precise length and improving cutting accuracy. Mechanical cutting by a cutting blade 200 further enhances cutting accuracy, achieving ±0.2mm. The unloading assembly 300 adsorbs the semi-finished membrane, and the dimensions of the semi-finished membrane are detected by scales on the bearing surface, further improving the dimensional accuracy of the finished membrane. In short, this application achieves automatic membrane cutting through the feeding assembly 100, cutting assembly, and unloading assembly 300, improving automation and reducing defects caused by manual intervention. This ensures dimensional consistency across multiple cut exchange membranes, reduces inspection time for operators and inspectors, meets membrane cycle time requirements, and improves cutting efficiency. Furthermore, by improving cutting efficiency, the setting of the carrier plate and adsorption hole 320 in the feeding component 300 facilitates the convenience of detecting whether the semi-finished film after cutting meets the size requirements, improves detection accuracy, and also helps to improve the dimensional accuracy of the final finished film, increase the yield, and benefit the efficiency and lifespan of the battery stack that uses the finished film.
