[0036] Reference throughout this specification to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the present application. Thus, when the phrases "in one embodiment," "in some embodiments," or "in some embodiments" appear in various places throughout this specification, not all references are to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
[0037] Please refer to Figures 1 to 6 As shown, the bipolar plate and flow channel plate bonding tool for liquid flow batteries provided by the present invention is now described. The bipolar plate and flow channel plate bonding tool for liquid flow batteries includes a tray 1, a printing plate 2, a positioning member 4 and a backing plate 5. The positioning member 4 is connected to the tray 1. The printing plate 2, the backing plate 5, and the bipolar plate 100 can be stacked on the tray 1 and positioned with the positioning member 4, so that the printing plate 2, the backing plate 5 or the bipolar plate 100 cannot move relative to the tray 1 along the stacking plane, as shown in FIG. Figure 5 and Figure 6 As shown, the center of the backing plate 5 is provided with a positioning portion 6 suitable for receiving the manifold plate 200. When the manifold plate 200 is received in the positioning portion 6 on the backing plate 5 and the backing plate 5 is positioned on the tray 1, the manifold plate 200, which is smaller than the bipolar plate 100, can be positioned on the tray 1. The printed board 2 is provided with a leakage hole 22.
[0038] After the tray 1 is positioned and matched with the bipolar plate 100, and the printed board 2 is then positioned and matched with the positioning member 4, and the printed board 2 and the bipolar plate 100 are attached, the leak holes 22 on the printed board 2 are relatively aligned with the glue dispensing areas set on the bipolar plate 100, so that the adhesive can be applied to the bipolar plate 100 by filling the leak holes 22 on the printed board 2 with adhesive. After the tray 1 is positioned and matched with the backing plate 5, and the flow channel plate 200 is placed in the positioning portion 6 of the backing plate 5, and the printed board 2 is then positioned and matched with the positioning member 4, and the printed board 2 and the flow channel plate 200 are attached, the leak holes 22 on the printed board 2 are relatively aligned with the glue dispensing areas set on the flow channel plate 200, so that the adhesive can be applied to the flow channel plate 200 by filling the leak holes 22 on the printed board 2 with adhesive. This allows precise dispensing of glue onto the bipolar plate 100 or manifold plate 200. Since the size of the eyelet 22 is fixed, the amount of adhesive filling the eyelet 22 is fixed, allowing precise control of the dispensing location and amount, resolving the issue of uncontrolled dispensing amount and location in the prior art. After dispensing, the printed board 2 is removed, and the manifold plate 200 is aligned and stacked with the bipolar plate 100 using the tray 1 and backing plate 5, allowing for precise bonding of the bipolar plate 100 and manifold plate 200.
[0039] like Figure 3 As shown, in some embodiments, the printing plate 2 is a rectangular plate structure, and a glue groove 21 is provided on the surface of the printing plate 2. A plurality of leak holes 22 are opened at the bottom of the glue groove 21, and a smooth surface 23 higher than the leak holes 22 is provided on the side of the leak holes 22, so that the adhesive is applied to the glue groove 21 and the adhesive is scraped on the smooth surface 23, so that the adhesive can flow into and fill the leak holes 22, so that the adhesive is attached to the bipolar plate 100 or the flow channel plate 200 for bonding, and the excess adhesive can be temporarily stored at the smooth surface 23 for subsequent use.
[0040] In some embodiments, the printed board 2 is an integrally formed structure, which makes the structure of the printed board 2 stable and reliable, avoids detailed processing and splicing, thereby saving production costs and avoiding matching errors caused by assembly.
[0041] like Figure 2 As shown, in some embodiments, the positioning member 4 is a pin structure, and the tray 1 is provided with a positioning hole 11 suitable for inserting the positioning member 4, so that the positioning member 4 can be inserted into and connected to the tray 1, and the printing plate 2 is provided with a positioning hole 24 suitable for plugging and cooperating with the positioning member 4, and the pad 5 is provided with a positioning hole 3 51 suitable for plugging and cooperating with the positioning member 4, so that when the printing plate 2 and the pad 5 are respectively plugged with the positioning member 4 through the positioning hole 24 and the positioning hole 3 51, the printing plate 2 and the pad 5 can be positioned and matched with the positioning member 4, so that the printing plate 2 and the pad 5 cannot move relative to the pallet 1 along the stacking plane, and the plug-in matching mode of the positioning member 4 and the positioning holes on the printing plate 2 and the pad 5 facilitates the installation and disassembly between the components.
[0042] like Figure 2 As shown, in some embodiments, a positioning hole four 101 is provided on the outer edge of the bipolar plate 100. The positioning hole four 101 on the bipolar plate 100 can not only be used to position the bipolar plate 100 and other components of the electrochemical reactor when assembling the electrochemical reactor, but the positioning hole four 101 on the bipolar plate 100 can also be plugged and positioned with the positioning piece 4 in the bonding tool for the bipolar plate and the flow channel plate for the liquid flow battery provided by the embodiment of the present invention. It can be understood that in some other embodiments not shown in the figures, the bipolar plate 100 can also be positioned by other structures not limited to the plug-in positioning structure, such as: a groove positioning structure, a fastener positioning structure, etc.
[0043] In some embodiments, the outline shape of the tray 1 is adapted to the outline shape of the bipolar plate 100 . Specifically, in this embodiment, the tray 1 is a rectangular plate structure adapted to the bipolar plate 100 .
[0044] In some embodiments, the size of the tray 1 is larger than that of the bipolar plate 100 so that the tray 1 can fully fit the bipolar plate 100 and facilitate uniform pressure on the bipolar plate 100 in the subsequent pressurization process.
[0045] In some embodiments, a receiving groove is provided on the back of the tray 1 to accommodate the tail end of the positioning member 7 of the pin structure to be received in the receiving groove, thereby keeping the back of the tray 1 flat.
[0046] like Figure 5 As shown, in some embodiments, the positioning portion 6 is a positioning groove formed in a hollow portion of the backing plate 5 .
[0047] like Figure 5 、 Figure 6 As shown, in some embodiments, the pad 5 is a symmetrical split structure, such as Figure 2 As shown, specifically, in this embodiment, there are two pads 5, and the two pads 5 can be installed on the positioning member 4 of the pallet 1 at intervals, so that the two pads 5 are spaced apart to form the positioning portion 6. It can be understood that in other embodiments not shown in the figures, the pad 5 can also be an asymmetric split structure or an integrated structure.
[0048] Figure 7 A schematic diagram shows the positions of the bipolar plate 100, the flow channel plate 200, the tray 1, the backing plate 5 and the printed board 2. Regardless of this positional relationship, these components do not necessarily need to appear simultaneously and can be combined according to actual needs.
[0049] It can be understood that when glue needs to be dispensed on the bipolar plate 100, the bipolar plate 100 is first stacked on the tray 1 and aligned with the positioning member 4, and then the printed board 2 is placed on the bipolar plate 100 and aligned with the positioning member 4. After glue is dispensed on the bipolar plate 100 through the printed board 2, the printed board 2 is removed, the pad 5 is stacked on the bipolar plate 100 and aligned with the positioning member 4, and the flow channel plate 200 is placed in the positioning portion 6 of the pad 5, so that the flow channel plate 200 is aligned and fitted on the bipolar plate 100.
[0050] In addition, when glue is required on the flow channel plate 200, Figure 4 As shown, the pad 5 is stacked on the tray 1 or the bipolar plate 100 and aligned with the positioning member 4, then the flow channel plate 200 is placed in the positioning portion 6 of the pad 5, and then the printed plate 2 is placed on the flow channel plate 200. After the printed plate 2 is glued to the flow channel plate 200, the printed plate 2 is removed, and the bipolar plate 100 is stacked on the flow channel plate 200 and aligned with the positioning member 4, so that the bipolar plate 100 is aligned and attached to the flow channel plate 200.
[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
