Description

Technical Field

[0001] This utility model relates to the field of flow battery technology, and in particular to a flow battery stack press-fit workstation. Background Technology

[0002] In the manufacturing process of flow batteries, bipolar plates and two electrode frames are typically pressed together under specific temperature and pressure using a sealing material (such as hot melt adhesive). This melts the adhesive and fills the gaps between the components, achieving initial sealing and fixation. Immediately after hot pressing, the components are transferred to a cold pressing device for cooling and pressing. Circulating cooling water solidifies the hot melt adhesive during the cold pressing process, further enhancing the component's sealing performance and structural stability. Through the combination of hot and cold pressing, the flow battery stack achieves efficient sealing and a stable structure, effectively preventing electrolyte leakage and improving battery safety and reliability.

[0003] However, existing technologies only allow a single cold or hot press to process one set of workpieces at a time, preventing multi-station parallel operations and resulting in longer cycle times and limited production capacity. Furthermore, increasing the number of cold or hot presses typically leads to a larger number of machines, a more dispersed layout, and a greater need for production space, resulting in a less compact workshop layout.

[0079] Reference Figure 1 , Figure 2 As shown, an embodiment of the present invention provides a flow battery stack press-fitting workstation for stacking and press-fitting workpieces, the workpieces comprising a first electrode plate frame, a bipolar plate, and a second electrode plate frame stacked sequentially. The flow battery stack press-fitting workstation includes:

[0081] A cold press 200 is disposed beside the hot press 100, and the cold press 200 is used to cold press the workpiece after hot pressing;

[0082] The transfer mechanism 300 is used to transfer the workpiece between the hot press 100 and the cold press 200.

The upper cold press lower mold 202 is disposed at the upper end of the cold press table 201. The upper cold press upper mold 203 is movable relative to the upper cold press lower mold 202 and forms an upper cold press working space with the upper cold press lower mold 202. The lower cold press upper mold 204 is disposed at the lower end of the cold press table 201. The lower cold press lower mold 205 is movable relative to the lower cold press upper mold 204 and forms a lower cold press working space with the lower cold press upper mold 204.

[0085] With the above configuration, the hot press 100 and the cold press 200 are respectively set with upper and lower working spaces, so that the same hot press 100 and cold press 200 can process two sets of workpieces at the same time, realize dual-station parallel operation, and greatly improve space utilization and production efficiency.

[0086] In one embodiment, refer to Figure 3 , Figure 4 As shown, to facilitate the precise movement of the lower hot-pressing mold 105 and the upper hot-pressing mold 103, the hot press 100 further includes: a hot press column 106, a hot press upper moving beam 107, and a hot press lower moving beam 108; the hot press column 106 is disposed on the hot press table 101 and extends along the upper and lower sides of the hot press table 101; the hot press upper moving beam 107 is connected to the upper hot pressing mold 103, and the hot press upper moving beam 107 is slidably connected to the hot press column 106 through a hot press upper moving beam slider 113; the hot press lower moving beam 108 is connected to the lower hot pressing mold 105, and the hot press lower moving beam 108 is slidably connected to the hot press column 106 through a hot press lower moving beam slider 114. This structure enables smooth mold movement and precise alignment, improving mechanical rigidity and stability during the pressing process and effectively preventing uneven pressing caused by mold misalignment, thereby ensuring the consistency and repeatability of pressing quality.

[0087] Specifically, four hot press columns 106 are located at the four corners of the hot press table 101.

[0088] In one embodiment, to facilitate the movement of the upper hot press mold 103 and the lower hot press mold 105, the hot press 100 further includes an upper crossbeam 109, an upper drive mechanism 110, a base 111, and a lower drive mechanism 112. The upper crossbeam 109 is connected to the upper end of the hot press column 106 and is located above the upper moving beam 107. The upper drive mechanism 110 is installed on the upper crossbeam 109 and its drive end is connected to the upper moving beam 107. The base 111 is connected to the lower end of the hot press column 106 and is located below the lower moving beam 108. The lower drive mechanism 112 is installed on the base 111 and its drive end is connected to the lower moving beam 108.

[0089] In this embodiment, the upper drive mechanism 110 and the lower drive mechanism 112 of the hot press are hydraulic cylinders. Precise pressure adjustment is achieved through hydraulic cylinder control, meeting the pressing requirements of fuel cell stacks of different specifications and improving process adaptability and controllability of the pressing process. Other drive mechanisms, such as pneumatic cylinders, can also be selected.

[0090] It should be noted that the upper hot pressing mold 103 and the lower hot pressing mold 104 are equipped with electric heating tubes or heating pipes. The heating pipes contain a heat-conducting medium or heating wire, and the heat-conducting medium is heat-conducting oil. When the upper hot pressing mold 103 or the lower hot pressing mold 104 comes into contact with the workpiece, heat can be transferred to the workpiece, causing the hot melt adhesive on the workpiece to melt and thus bond the two electrode plate frames and the bipolar plates. Furthermore, heating is controlled by an auxiliary electrical cabinet 1200 located on one side of the hot press 100.

[0091] In one embodiment, refer to Figure 5 , Figure 6As shown, to facilitate the precise movement of the lower cold-pressing mold 205 and the upper cold-pressing mold 203, the cold press 200 also includes a cold press column 206, a cold press upper moving beam 207, and a cold press lower moving beam 208. The cold press column 206 is disposed on the cold press table 201 and extends along the upper and lower sides of the cold press table 201. The cold press upper moving beam 207 is connected to the upper cold-pressing mold 203, and the cold press upper moving beam 207 is slidably connected to the cold press column 206 through a cold press upper moving beam slider 213. The cold press lower moving beam 208 is connected to the lower cold-pressing mold 205, and the cold press lower moving beam 208 is slidably connected to the cold press column 206 through a cold press lower moving beam slider 214. This structure enables smooth mold movement and precise alignment, improving mechanical rigidity and stability during the pressing process and effectively preventing uneven pressing caused by mold misalignment, thereby ensuring the consistency and repeatability of pressing quality.

[0092] Specifically, four hot press columns 106 are located at the four corners of the hot press table 101.

[0093] In one embodiment, to facilitate the movement of the upper cold-pressing mold 203 and the lower cold-pressing mold 205, the cold press 200 further includes an upper crossbeam 209, an upper drive mechanism 210, a base 211, and a lower drive mechanism 212. The upper crossbeam 209 is connected to the upper end of the cold press column 206 and is located above the upper moving beam 207. The upper drive mechanism 210 is installed on the upper crossbeam 209 and its drive end is connected to the upper moving beam 207. The base 211 is connected to the lower end of the cold press column 206 and is located below the lower moving beam 208. The lower drive mechanism 212 is installed on the base 211 and its drive end is connected to the lower moving beam 208.

[0094] In one embodiment, the upper drive mechanism 210 and the lower drive mechanism 212 of the cold press are hydraulic cylinders, but other drive mechanisms, such as pneumatic cylinders, can also be selected.

[0095] It should be noted that both the upper cold-pressing die 203 and the lower cold-pressing die 204 have cooling pipes containing a cooling medium, such as cooling water. Through the cooling medium, when the upper cold-pressing die 203 or the lower cold-pressing die 204 comes into contact with the workpiece, it can flatten or cool the workpiece. Its main function is to cool the workpiece, thereby reducing the temperature of the electrode plate frame in a timely manner and preventing deformation of the electrode plate frame during the cooling process.

[0096] In one embodiment, refer to Figure 8As shown, the transfer mechanism 300 employs an industrial robotic arm (industrial robot). Controlled by the robot control cabinet 1300, it can automate operations such as gripping and handling, ensuring stable and efficient transfer of workpieces between cold and hot pressing processes, greatly improving production cycle time and reducing labor costs.

[0097] In one embodiment, refer to Figure 1 As shown, it also includes a first electrode plate frame loading platform 400, a second electrode plate frame loading platform 500, a bipolar plate loading platform 600, a bipolar plate positioning platform 700, a bipolar plate positioning platform 700, and an electrode plate frame positioning platform 800 arranged around the transfer mechanism 300.

[0098] The first electrode plate frame loading platform 400 is used to load and temporarily store the first electrode plate frame;

[0099] The second electrode plate frame loading platform 500 is used to load and temporarily store the second electrode plate frame;

[0100] The bipolar plate loading platform 600 is used for loading and temporarily storing bipolar plates;

[0101] The bipolar plate positioning platform 700 is used for positioning bipolar plates;

[0102] The electrode plate frame positioning platform 800 is used to position the first electrode plate frame and the stacked first electrode plate, bipolar plate, and second electrode plate frame.

[0103] The unloading platform 900 is used to place the workpieces after they have been pressed.

[0104] It should be noted that, referring to Figure 7 As shown, multiple positioning blocks 710 are provided on the bipolar plate positioning platform 700 and the electrode plate frame positioning platform 800. The positioning blocks 710 can be adjusted by extending and retracting along the positioning platform by a cylinder.

[0105] During stacking, the first electrode plate frame is placed on the electrode plate frame positioning platform 800 by the transfer mechanism 300 and accurately positioned. After the first electrode plate frame is positioned, the transfer mechanism 300 transfers a bipolar plate to the bipolar plate positioning platform 700, accurately positions the bipolar plate, and moves it to the stacking position to be stacked on top of the first electrode plate frame; the electrode plate frame positioning platform 800 receives the second electrode plate frame, stacks it on top of the bipolar plate, and then positions it.

[0106] In one embodiment, refer to Figure 1As shown, it also includes a hydraulic control system 1000 and an industrial chiller system 1100. The hydraulic control system 1000 is connected to the hot press 100 and the cold press 200 respectively, and is used to connect to their respective drive mechanisms (cylinders). The industrial chiller system 1100 is connected to the cold press 200 to provide the required cooling water.

[0107] In this invention, during tooling, the first electrode plate frame, bipolar plate, and second electrode plate frame are first placed on the corresponding first electrode plate frame loading platform 400, bipolar plate loading platform 600, and second electrode plate frame loading platform 500, respectively. An industrial robot, following a predetermined sequence, picks up various components from each loading platform and transfers them to the electrode plate frame positioning platform 800 and the bipolar plate positioning platform 700. On the positioning platforms, multiple positioning blocks 710 precisely position and pre-stack each workpiece, ensuring accurate positioning of each component and forming a stacked workpiece to be pressed.

[0108] After stacking and positioning, the workpieces are transferred by the transfer mechanism 300 to the designated working space (upper or lower hot pressing working space) of the hot press 100. Driven by hydraulic cylinders, the upper moving beam 107 and the lower moving beam 108 of the hot press 100 respectively move the upper and lower molds of the hot press 100, heating and pressing the stacked workpieces together. The hot melt adhesive melts at a suitable temperature, fully filling the gap between the bipolar plates and the electrode plate frame, achieving initial sealing and bonding of the electrode stack and improving structural stability.

[0109] After hot pressing is completed, the transfer mechanism 300 removes the hot-pressed workpiece from the hot press 100 and quickly sends it into the designated working space (upper or lower cold pressing working space) of the cold press 200.

[0110] The upper and lower moving beams of the cold press 200, driven by hydraulic or pneumatic forces, drive the upper and lower cold pressing molds to apply pressure to the hot-pressed workpiece. At the same time, the workpiece is rapidly cooled by cooling water and other cooling media flowing in the cooling pipes, which solidifies the hot melt adhesive, further enhancing the sealing and mechanical strength of the fuel cell stack, and effectively preventing workpiece deformation and performance degradation caused by sudden temperature changes or prolonged residence.

[0111] After cold pressing, the transfer mechanism 300 removes the press-formed flow battery stack assembly from the cold press 200 and transfers it to the unloading platform 900. The unloading platform 900 is used for the orderly collection and temporary storage of finished products, facilitating subsequent quality inspection, assembly, or packaging processes.

[0112] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
