Description

Technical Field

[0001] The utility model relates to the field of liquid flow batteries, in particular to an automatic stacking device for all-vanadium liquid flow battery stacks. Background Art

[0002] All-vanadium redox flow batteries (AVFBs) are liquid flow batteries using vanadium as the active material in a circulating, flowing liquid state. They consist of a stack unit, electrolyte, electrolyte storage and supply unit, and a management and control unit. A AVFB is a high-performance battery that utilizes separate circulation of the positive and negative electrolytes. It boasts high capacity, a wide range of applications (environments), and a long cycle life.

[0003] At present, during the assembly process of all-vanadium liquid flow batteries, the stacking quality of the plates is crucial to the quality and performance of the all-vanadium liquid flow batteries. In order to ensure the stacking quality of the plates, corresponding tooling is usually added to the all-vanadium liquid flow battery stacking equipment to assist in the stacking of the plates. Common tooling, such as that shown in patents with publication numbers CN221327800U and CN220895560U, ensures that the plates remain neat during the stacking process by arranging limiting components such as limiting plates around the plates, thereby ensuring the stacking quality of the plates. This type of plate stacking tooling has a simple structure and excellent limiting effect, which can meet the stacking requirements of the plates. However, its service life is generally short. After long-term use, the limiting effect decreases, the stacking error of the plates increases, and it is difficult to continue to ensure the stacking quality of the plates. The reason is that the limiting surface on the limiting components such as the limiting plate, which contacts the edge of the plate and plays a limiting role, wears out due to long-term contact and friction with the plate, resulting in the limiting surface no longer being flat and losing its limiting function. Based on this, the present utility model is designed. Utility Model Content

[0043] The present invention proposes an automated stacking device for all-vanadium liquid flow battery stacks. The automated stacking device for all-vanadium liquid flow battery stacks uses a laser and a visual camera 25 to cooperate with each other to perform real-time positioning monitoring on the stacking process of the electrode plates 14. Once it is found that the stacking of the electrode plates 14 is uneven, the horizontal push device 4 can be controlled to push the positioning rod 6 to position the problematic electrode plates 14 in the first time to restore the stacking to an even state. After positioning, the positioning rod 6 is reset and separated from the electrode plates 14. Therefore, the positioning surface on the positioning rod 6 is not easy to wear, and can provide long-term precise positioning requirements, thereby ensuring the stacking quality of the electrode plates 14 for a long time.

[0044] Specifically, in one embodiment of the present invention, Figure 1 As shown, the automated stacking equipment for all-vanadium liquid flow battery stacks includes: stacking plates 12, multiple positioning rods 6, a horizontal pushing device 4, multiple lasers, multiple visual cameras 25, a robot and a press 16. The upper surface of the stacking plates 12 is horizontal, and the upper surface of the stacking plates 12 can be stacked with partitions 13 and pole plates 14.

[0045] In this embodiment, the stacking process of the all-vanadium liquid flow battery stack is as follows: first, a partition 13 is horizontally placed on the upper surface of the stacking plate 12, and then a plurality of electrode plates 14 are stacked on the upper surface of the partition 13. Finally, another partition 13 is placed on the upper surface of the uppermost electrode plate 14. Then, a press 16 is used to press the stacked partitions 13 and electrode plates 14 together, and the upper and lower partitions 13 are fixedly connected with bolts.

[0046] In this embodiment, if Figure 1 and Figure 5 As shown, a plurality of positioning rods 6 are evenly distributed around the stacking plate 12, and the positioning rods 6 are vertically arranged, and the lower ends of the positioning rods 6 are flush with the stacking plate 12. With this design, the positioning rods 6 can move horizontally to position the multiple stacked plates 14 and the uppermost partition 13, so that the stacked plates 14 and the partitions 13 remain aligned in the vertical direction, thereby ensuring the stacking quality of the plates 14.

[0047] In this embodiment, if Figure 1 and Figure 5 As shown, the horizontal pushing device 4 is connected to the positioning rod 6, and the horizontal pushing device 4 is used to push the positioning rod 6 to move horizontally closer to or away from the stacking plate 12, thereby positioning the stacked electrode plates 14 and partitions 13, so that the stacked electrode plates 14 and partitions 13 remain aligned in the vertical direction, thereby ensuring the stacking quality of the electrode plates 14.

[0048] In this embodiment, if Figure 1 and Figure 4 As shown, multiple lasers are evenly distributed above the surrounding of the stacked plate 12. The multiple surface lasers emitted by the multiple lasers are all vertically downward and can be tangent to all edge sides of the partition 13 and the plate 14. The irradiation direction of the surface laser is as shown in FIG. Figure 1 As shown by the arrow in the middle, specifically, the laser includes a laser 19 and a laser 23, and the partition 13 and the plate 14 are both rectangular. Figure 6-Figure 8As shown, the laser surface 120 emitted by the laser 19 is vertically aligned with the side of the long side of the stacked electrode plate 14, and the laser surface 24 emitted by the laser 23 is vertically aligned with the side of the short side of the stacked electrode plate 14. With this design, when the electrode plates 14 are stacked and not aligned with the electrode plates 14 below them in the vertical direction, the laser surface 120 and / or the laser surface 24 will be completely or partially blocked by the electrode plates 14, resulting in incomplete projection of the laser surface 120 and / or the laser surface 24 on the upper surface of the partition 13. Based on this, it can be judged that when the electrode plates 14 are stacked in the process of stacking the all-vanadium liquid flow battery stack, they are not aligned with the electrode plates 14 below them in the vertical direction, and then the horizontal pushing device 4 is controlled to push multiple positioning The rod 6 moves to position the electrode plate 14 until the projection of the laser surface 1 20 and / or the laser surface 2 24 on the upper surface of the partition 13 is completely restored. It can be seen that the positioning rod 6 does not normally contact the electrode plate 14 and the partition 13. Only when the electrode plates 14 and the partitions 13 are not stacked neatly, the horizontal pushing device 4 pushes multiple positioning rods 6 to move to position the electrode plates 14 and the partitions 13, and contacts the electrode plates 14 and the partitions 13. After positioning, the horizontal pushing device 4 drives multiple positioning rods 6 to reset and separate from the electrode plates 14 and the partitions 13. The positioning surface on the positioning rod 6 has less contact friction with the electrode plates 14 and the partitions 13, so the positioning surface on the positioning rod 6 is not easy to wear, and can provide accurate positioning requirements for a long time, thereby ensuring the stacking quality of the electrode plates 14 for a long time.

[0049] In this embodiment, if Figure 1 As shown, multiple visual cameras 25 are evenly distributed above the surrounding of the stacked plates 12. The multiple visual cameras 25 can capture all edge sides of the stacked separators 13 and plates 14. The shooting direction 26 of the visual cameras 25 is as shown in FIG. Figure 1 As shown by the middle arrow, with this design, the visual camera 25 can identify whether the projection of the laser surface 1 20 and / or the laser surface 2 24 is complete, and whether there is a laser projection on the upper surface of the electrode plate 14 and the partition 13, thereby providing the computer with an instruction reference for whether to control the action of the horizontal pushing device 4. For example, when the visual camera 25 detects that there is a laser projection on the upper surface of a certain electrode plate 14 or partition 13, it means that the electrode plate 14 or partition 13 is not stacked neatly, and the detection data is sent to the computer, and the computer controls the action of the horizontal pushing device 4 to push the electrode plate 14 and partition 13 to be positioned and stacked neatly.

[0050] In this embodiment, the robot is located next to the stacking plate 12 and is used to pick up the separators 13 and the electrode plates 14 and place the separators 13 and the electrode plates 14 on the upper surface of the stacking plate 12, thereby realizing automatic stacking of the all-vanadium liquid flow battery stack.

[0051] In this embodiment, the press 16 is arranged directly above the stacking plate 12. When the all-vanadium liquid flow battery stack is stacked, the press 16 is controlled to press down to compact the stacked partitions 13 and plates 14, and then the robot is controlled to fix the upper and lower partitions 13 together with bolts.

[0052] During the operation of the automated stacking equipment for the all-vanadium liquid flow battery stack of this embodiment, the robot continuously and automatically takes the partitions 13 and the electrode plates 14 from other places and places them on the stacking plate 12. The laser and the visual camera 25 work continuously. Once the visual camera 25 detects that there is a laser projection on the upper surface of a certain electrode plate 14 or partition 13, it means that the electrode plate 14 or partition 13 is not stacked neatly and needs to be positioned and adjusted. Therefore, the computer controls the horizontal pushing device 4 to push the corresponding positioning rod 6 to move horizontally close to the electrode plate 14 or partition 13 to position the electrode plate 14 or partition 13. Then the visual camera 25 rechecks until there is no laser projection on the upper surface of the electrode plate 14 or partition 13. Then the robot can continue the stacking operation. After the stacking is completed, the press 16 presses down to compact the stacked partitions 13 and electrode plates 14. Then the robot uses bolts to fix the upper and lower partitions 13 together, thereby completing the stacking assembly of the all-vanadium liquid flow battery stack.

[0053] In this embodiment, if Figure 1 、 Figure 4 As shown, the laser 23 is located above the short sides of the partition 13 and the electrode 14, and multiple lasers 23 are arranged at equal intervals and arranged in a straight line along the short sides. The multiple laser surfaces 24 emitted by the multiple lasers 23 above the short sides are all vertically downward and vertically aligned with the side surfaces of the stacked electrode 14 where the short sides are located. Similarly, the laser 19 is located above the long sides of the partition 13 and the electrode 14, and multiple lasers 19 are arranged at equal intervals and arranged in a straight line along the long sides. The multiple laser surfaces 20 emitted by the multiple lasers 19 above the long sides are all vertically downward and vertically aligned with the side surfaces of the stacked electrode 14 where the long sides are located. In this way, Figure 6-Figure 8 As shown, when the plates 14 are stacked neatly, the laser surface 1 20 and the laser surface 2 24 will only be aligned and tangent to the side surfaces of the plate 14 in the vertical direction, and the laser surface 1 20 and the laser surface 2 24 will not illuminate the upper surface of the plate 14. Therefore, once there is a laser projection on the upper surface of the plate 14, it means that the plates 14 are not stacked neatly, and it is necessary to control the horizontal pushing device 4 to push the positioning rod 6 to move horizontally for adjustment.

[0054] Further, such as Figure 1 and Figure 4As shown, multiple lasers 19 located above any long side are fixedly connected to mounting plate 2 18, and mounting plate 2 18 is connected to linear motor 8, and linear motor 8 is fixedly connected to mounting plate 1 15. The linear motor 8 is used to drive mounting plate 2 18 to translate, and the translation direction is perpendicular to the long side. Multiple lasers 23 located above any short side are fixedly connected to mounting plate 3 22, and mounting plate 3 22 is connected to linear motor 8, and linear motor 8 is fixedly connected to mounting plate 1 15. The linear motor 8 is used to drive mounting plate 3 22 to translate, and the translation direction is perpendicular to the short side. With this design, the positions of laser 19 and laser 2 23 can be adjusted according to the length of the side of the electrode plate 14 and the partition 13 to ensure that the laser surface 2 24 and the laser surface 1 20 can be aligned and tangent to the side surfaces of the electrode plates 14 and partitions 13 of various specifications and sizes in the vertical direction, thereby expanding the application range of the automatic stacking equipment of the all-vanadium liquid flow battery stack of this embodiment and having good practicality.

[0055] In this embodiment, if Figure 1 and Figure 2 As shown, a base plate 2 is provided below the stacking plate 12, and a support leg 1 and a motor 8 are provided on the lower surface of the base plate 2. A guide column 2 and a screw 9 are vertically penetrated on the base plate 2, and the guide column 2 is vertically slidably connected to the base plate 2, and the upper end of the guide column 2 is fixedly connected to the stacking plate 12. A through hole 10 is provided on the base plate 2, and the aperture of the through hole 10 is larger than the diameter of the screw 9. The screw 9 passes through the through hole 10 and does not contact the base plate 2. The upper end of the screw 9 is screwed to the screw hole 11 on the stacking plate 12, and the lower end of the screw 9 is transmission-connected to the motor 8. With this design, after the motor 8 is started, the screw 9 can be provided to drive the stacking plate 12 to rise and fall, so as to adjust the height of the stacking plate 12 to adapt to the positioning requirements of the plates 14 and partitions 13 of different thicknesses, thereby expanding the application range of the automatic stacking equipment of the all-vanadium liquid flow battery stack of this embodiment and having good practicality.

[0056] In this embodiment, if Figure 1 and Figure 5 Described, the column 3 is fixedly installed on the base plate 2, and the pushing device 4 is fixedly connected to the column 3; further, the guide column 5 is horizontally slidably installed on the column 3, and the guide column 5 is fixedly connected to the positioning rod 6. The horizontal sliding direction of the guide column 5 is the same as the pushing action direction of the pushing device 4. Such design can improve the translational stability of the positioning rod 6.

[0057] Preferably, in this embodiment, Figure 1As shown, the positioning rod 6 includes a straight rod 61 and a bent rod 62 provided at the upper and lower ends of the straight rod 61, the bent rod 62 is L-shaped, and a bending angle 27 of 90 degrees is provided on the side of the bent rod 62 facing the stacked separator 13 and the plate 14. The bent rod 62 includes a horizontal rod 28 and a vertical rod 29 fixedly connected vertically. One end of the horizontal rod 28 is fixedly connected to the straight rod 61, and the other end of the horizontal rod 28 is fixedly connected to the vertical rod 29. The vertical axis symmetry plane of the straight rod 61 and the bent rod 62 is parallel to the horizontal push action direction of the horizontal push device 4. Such a design, as Figure 3 As shown, the electrode plate 14 can be positioned by the straight rod 61 and the partition 13 can be positioned by the bent rod 62, which fully meets the positioning requirements when the electrode plate 14 and the partition 13 are of different sizes.

[0058] Normally, the size of the partition 13 is larger than the electrode plate 14, which makes it convenient for the robot to fix the upper and lower partitions 13 together with bolts. Therefore, after the robot places the partition 13 on the stacking plate 12, if the visual camera 25 detects that there is a laser projection on the upper surface of the partition 13, and the laser surface 2 24 and the laser surface 1 20 are not vertically aligned and tangent to the side of the partition 13, it means that the position of the partition 13 needs to be repositioned. At this time, the computer controls the horizontal push device 4 to push the positioning rod 6 to use the 90-degree bending angle 27 of the bending rod 62 to position the partition 13. After positioning is completed, the visual camera 25 re-checks. If the laser surface 2 24 and the laser surface 1 20 are vertically aligned and tangent to the side of the partition 13, the partition 13 needs to be repositioned. If there is no laser projection on the upper surface of the plate 13, it means that the partition 13 has been positioned. At this time, the robot can place the first electrode plate 14 on the upper surface of the partition 13. Because the size of the electrode plate 14 is smaller than the partition 13, the linear motor 81 and the linear motor 82 need to act in time to adjust the position of the laser 19 and the laser 2 23 so that the laser surface 2 24 and the laser surface 1 20 are vertically aligned and tangent to the side of the electrode plate 14. After the uppermost partition 13 is placed on the electrode plate 14 and positioned, the press 16 presses down to tighten the stacked partitions 13 and the electrode plates 14, and then the robot fixes the upper and lower partitions 13 with bolts, thereby completing the stacking assembly of the all-vanadium liquid flow battery stack.

[0059] In this embodiment, when the thickness of the partition 13 changes, as shown in FIG. Figure 3 As shown, in order to ensure that the positioning rod 6 can still normally position the partition 13 and the electrode plate 14 later, it is necessary to control the motor 8 to adjust the height of the stacking plate 12 so that the position of the stacking plate 12 can adapt to the partitions 13 of different thicknesses, so that the upper surface of the partition 13 can be attached to the cross bar 28, and the two ends of the electrode 14 are in contact with the straight rod 61, without affecting the positioning function of the positioning rod 6.

[0060] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the utility model concept, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
