Description

Technical Field

[0001] This utility model relates to the field of bipolar plate packaging technology for flow batteries, and in particular to a graphite plate packaging device for flow batteries. Background Technology

[0002] Graphite plates in flow batteries, typically referring to bipolar plates, are crucial components. They function as separators, connect cells in series, conduct current, and provide structural support for the battery stack. Graphite bipolar plates possess advantages such as high chemical stability, good corrosion resistance, high conductivity, and low density. Graphite-based composite bipolar plates, by adding auxiliary conductive carbon materials, reinforcing materials, and resin as a binder to the graphite matrix, maintain the excellent conductivity and chemical stability of graphite while reducing costs. Graphite bipolar plates and graphite-based composite bipolar plates are widely used in flow battery systems with corrosive electrolytes, such as vanadium redox flow batteries. Graphite plates play a key role in flow batteries, and their performance and manufacturing technology represent an important direction for the development of flow battery technology. With technological advancements and increasing market demand, the application and research of graphite plates will continue to expand.

[0003] Currently, when packing bipolar plates for flow batteries, each layer of bipolar plates needs to be padded with a pad to cushion and reduce shock during transportation. However, workers manually and alternately place the bipolar plates and pads into the packaging box, which involves a large amount of work and has low packing efficiency.

[0004] Therefore, a graphite plate packaging device for flow batteries is proposed to solve the above problems. Utility Model Content

[0005] The main purpose of this utility model is to provide a packaging device for graphite large plates of flow batteries, which aims to solve the technical problems in the prior art.

[0006] This utility model proposes a packaging device for graphite plates of flow batteries, comprising: an operating table, on the side of which are respectively installed a bipolar plate conveyor for conveying bipolar plates, a pad conveyor for conveying pads, and a packaging mechanism for placing and conveying packaging boxes; a feeding mechanism installed on the top of the operating table, capable of alternately placing pads and bipolar plates into packaging boxes on the packaging mechanism; a connecting cylinder installed on the feeding mechanism; a hexagonal stepper motor shaft installed on the top of the operating table; a hexagonal hole on the connecting cylinder for connecting to the stepper motor shaft; and a stepper motor installed inside the operating table and connected to the stepper motor shaft. The stepper motor automatically returns to its original position after rotating clockwise twice consecutively, with a five-second interval between each rotation.

[0007] Support arms are installed on the two vertical sides of the outer ring surface of the connecting cylinder. Electric push rods are installed at the top of the support arms, and electric suction cups are installed at the bottom of the electric push rods. The two electric suction cups are located directly above the foremost pad and bipolar plate on the pad conveyor frame and the bipolar plate conveyor frame, respectively.

[0008] After the stepper motor shaft rotates clockwise once, the pad is positioned directly above the packaging box. After rotating clockwise once more, the bipolar plate is positioned directly above the packaging box. The electric push rods above the bipolar plate conveyor and the pad conveyor are controlled by a customized program. Each time the two electric push rods move into the packaging box, the distance is shorter than the previous distance by the thickness of one pad plus one bipolar plate until the packaging box is full. The above process is repeated. When the electric push rods stop extending, the electric suction cup automatically depresses and releases the pad or bipolar plate.

[0009] Preferably, the end of the pad conveyor and the bipolar plate conveyor near the operating table is a closed structure, and the pads and bipolar plates on the pad conveyor and the bipolar plate conveyor will be squeezed at the closed end during the conveying process until the first pad or bipolar plate is removed.

[0010] Preferably, the packing mechanism is equipped with a feeding rack, one end of which is equipped with a rectangular cover. An electric push rod is installed at the center of the bottom inner side of the rectangular cover. A limiting plate is installed around the inner top wall of the rectangular cover. A lifting plate with dimensions matching the bottom dimensions of the packaging box is installed on the top of the rectangular cover. A slot is opened around the outer side of the lifting plate to engage with the limiting plate. Without external support, the lifting plate will sink 3cm into the top of the rectangular cover to form a feeding groove.

[0011] Preferably, the top of the electric push rod three is fixedly connected to the bottom center of the lifting plate. After the electric push rod three pushes the lifting plate upward, the top of the lifting plate is flush with the top of the rectangular cover. One end of the feeding rack is equipped with an inclined plate to facilitate the sliding of the packaging box. The inner side of the feeding rack is equipped with a packaging box conveyor belt between the rectangular cover and the inclined plate. The top height of the packaging box conveyor belt is flush with the top height of the rectangular cover.

[0012] Preferably, a groove is provided on one side of the operating table, and an electric push rod is installed inside the groove. A push plate is installed at one end of the electric push rod, and the electric push rod can push the packaging box onto the packaging box conveyor belt through the push plate after it is extended.

[0013] The beneficial effects of this utility model are as follows: This utility model uses a pad conveyor and a bipolar plate conveyor to transport pads and bipolar plates. Two electric suction cups on the feeding mechanism respectively adsorb one pad and one bipolar plate, and the pad and bipolar plate are rotated to the top of the packaging box by stepping rotation. The pad and bipolar plate are alternately placed into the packaging box by electric push rod two, and finally transported by the packaging box conveyor belt. There is no need to manually alternately place the pad and bipolar plate into the packaging box layer by layer, which effectively reduces the amount of manual operation and significantly improves the packing efficiency of graphite plates for flow batteries.

[0020] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0021] like Figures 1-4As shown, this application provides a flow battery graphite plate packaging device, including: an operating table 1, on the side of the operating table 1 are respectively installed a bipolar plate conveyor 3 for conveying bipolar plates, a pad conveyor 4 for conveying pads, and a packaging mechanism 5 for placing and conveying packaging boxes. The top of the operating table 1 is equipped with a feeding mechanism 2 that can alternately place pads and bipolar plates into the packaging boxes on the packaging mechanism 5. The feeding mechanism 2 is used to alternately place the pads and bipolar plates on the pad conveyor 4 and the bipolar plate conveyor 3 into the packaging boxes on the packaging mechanism 5, thereby eliminating the need for manual feeding, reducing the amount of manual operation, and significantly improving the packaging efficiency of flow battery graphite plates.

[0022] In this embodiment, as Figure 1 As shown, the pad conveyor 4 and the bipolar plate conveyor 3 are both closed structures at the end near the operating table 1. During the conveying process, the pads and bipolar plates on the pad conveyor 4 and the bipolar plate conveyor 3 will be squeezed at the closed end until the first pad or bipolar plate is removed. This structure can ensure that each pad or bipolar plate is conveyed to the same position for picking.

[0023] In this embodiment, as Figure 1 and Figure 2 As shown, a connecting cylinder 21 is installed on the feeding mechanism 2. The connecting cylinder 21 is located on the top of the operating table 1. Support arms 22 are installed on the two vertical sides of the outer ring surface of the connecting cylinder 21. Electric push rods 23 are installed at the top end of the support arms 22. Electric suction cups 24 are installed at the bottom of the electric push rods 23. The two electric suction cups 24 are located directly above the foremost pad and bipolar plate on the pad conveyor frame 4 and the bipolar plate conveyor frame 3, respectively. Therefore, when the electric push rods 23 drive the electric suction cups 24 to move downward, the pad and bipolar plate can be adsorbed and picked up.

[0024] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, a connecting cylinder 21 is installed on the feeding mechanism 2, and a hexagonal stepper motor shaft 11 is installed on the top of the operating table 1. The connecting cylinder 21 has a hexagonal hole for connection with the stepper motor shaft 11. A stepper motor is installed inside the operating table 1 and connected to the stepper motor shaft 11. The stepper motor rotates 90° clockwise twice consecutively and then automatically returns to its original position, with a five-second interval between each rotation. After one clockwise rotation of the stepper motor shaft 11, the pad is positioned directly above the packaging box. After another clockwise rotation, the bipolar plate is positioned directly above the packaging box. The bipolar plate conveyor frame 3 and... After being adjusted by a customized program, the electric push rods 23 above the pad conveyor 4 move into the packaging box each time by a distance equal to the thickness of one pad plus one bipolar plate, until the packaging box is full. The process is repeated. When the electric push rods 23 stop extending, the electric suction cup 24 automatically releases air to release the pad or bipolar plate. When the two electric push rods 23 move into the packaging box for the first time, the pad and bipolar plate are stacked on the bottom of the inner side of the packaging box. Therefore, the inner side of the packaging box can be gradually stacked with one pad and one bipolar plate.

[0025] In this embodiment, as Figure 1 and Figure 4 As shown, a feeding rack 51 is installed on the packing mechanism 5. A rectangular cover 53 is installed at one end of the feeding rack 51. An electric push rod 55 is installed at the center of the bottom of the inner side of the rectangular cover 53. A limiting plate 54 is installed around the inner side wall of the top of the rectangular cover 53. A lifting plate 56 with a size matching the bottom size of the packaging box is installed on the top of the rectangular cover 53. A slot 57 is opened around the outer side of the lifting plate 56 and it is snapped into the limiting plate 54. Without external support, the lifting plate 56 will sink 3cm into the top of the rectangular cover 53 to form a feeding groove. This structure can facilitate the quick placement of the packaging box into the designated position each time.

[0026] In this embodiment, as Figure 4As shown, the top of the electric actuator 55 is fixedly connected to the bottom center of the lifting plate 56. After the electric actuator 55 pushes the lifting plate 56 upward, the top of the lifting plate 56 is flush with the top of the rectangular cover 53. One end of the loading rack 51 is equipped with an inclined plate 52 to facilitate the sliding of the packaging box. The inner side of the loading rack 51, located between the rectangular cover 53 and the inclined plate 52, is equipped with a packaging box conveyor belt 58. The top height of the packaging box conveyor belt 58 is flush with the top height of the rectangular cover 53. A recessed area is provided on one side of the operating table 1. The groove 12 has an electric push rod 13 installed on its inner side. One end of the electric push rod 13 is equipped with a push plate 14. When the electric push rod 13 is extended, it can push the packaging box onto the packaging box conveyor belt 58 through the push plate 14. After a packaging box is packed, the electric push rod 13 55 can be used to lift the lifting plate 56, and then the electric push rod 13 can be used with the push plate 14 to push the packaging box onto the packaging box conveyor belt 58 for unloading and conveying. This allows for quick replacement of new packaging boxes and improves packing efficiency.

[0027] The technical principle of this utility model is as follows: When using the graphite plate packing device for flow batteries, a packaging box is first placed in the loading groove formed by the lifting plate 56 and the rectangular cover 53. Then, two electric push rods 23 simultaneously drive two electric suction cups 24 to move downwards, respectively picking up the pads and bipolar plates from the bipolar plate conveyor 3 and the pad conveyor 4. Then, the stepper motor shaft 11 rotates 90° clockwise twice, with an interval of five seconds, so that the pads and bipolar plates are alternately positioned directly above the packaging box. Then, the electric push rods 23 drive the pads and bipolar plates into the packaging box for stacking. Since the electric push rods 23 above the bipolar plate conveyor 3 and the pad conveyor 4 move a shorter distance than the previous one when moving into the packaging box, the distance is reduced by the thickness of one pad plus one bipolar plate until the packaging box is full. Then, the above process is repeated. When the electric push rod 23 stops extending, the electric suction cup 24 automatically depresses to release the pad or bipolar plate. When the two electric push rods 23 move into the packaging box for the first time, the pad and bipolar plate are stacked on the bottom of the inner side of the packaging box. Therefore, the inner side of the packaging box can be gradually stacked with one pad and one bipolar plate, without the need for manual alternating placement of the pad and bipolar plate into the packaging box layer by layer. This effectively reduces the amount of manual operation and significantly improves the packing efficiency of the graphite plates of the flow battery. After the packaging box is full, the lifting plate 56 is lifted by the electric push rod 3 55, and then the packaging box is pushed onto the packaging box conveyor belt 58 by the push plate 14 through the electric push rod 1 13 for unloading and conveying. This allows for quick replacement of new packaging boxes and improves packing efficiency.
