[0033] Example
[0034] like Figure 1-6 As shown, a tool for stacking plates in an embodiment of the utility model is used for stacking plates 4 of a hydrogen fuel cell stack, and the plates 4 are provided with hole structures arranged along a first direction and used for positioning during stacking. In this embodiment, the first direction is the X direction shown in the figure.
[0035] Generally speaking, the hole structure can be a positioning hole structure set on the electrode plate 4, or a channel inlet or a channel outlet on the electrode plate 4. When the electrode plates 4 are stacked, a suitable hole structure can be selected according to the structural design of the electrode plates 4 themselves as the positioning hole when the electrode plates 4 are stacked.
[0036] like Figure 1 As shown, the tooling for stacking the electrode plates includes a support plate 1, one surface of which is a support surface 10 for placing the electrode plate 4; at least two limiting holes 11 arranged along a first direction are provided on the support plate 1, and a positioning block 2 that can move along the first direction is provided in each limiting hole 11.
[0037] The positioning block 2 is a strip-shaped structure and extends toward the outside of the support surface 10 along the second direction, and is used to pass through the hole for positioning when the electrode plate 4 is stacked. The end of the positioning block 2 extending to the outside of the support surface 10 is provided with a guide surface 20 for guiding the electrode plate 4 to penetrate. The circumference of the positioning block 2 is provided with a limiting surface 21 for limiting the rotation of the electrode plate 4.
[0038] It should be noted that the second direction is perpendicular to the first direction. In this embodiment, the second direction is the Y direction shown in the figure.
[0039] It should be noted that, due to the different sizes of the pole plates 4, the spacing of the hole structures of different pole plates 4 is different. In order to expand the universality of the tooling for stacking pole plates, the number of the limiting holes 11 can be multiple, and the multiple limiting holes 11 are arranged along the first direction. According to the structure of the pole plates 4 to be stacked, the positioning block 2 is installed in the limiting hole 11 at the corresponding position, or the limiting hole 11 is arranged as a long hole structure in the first direction. According to the structure of the pole plates 4 to be stacked, the position of the positioning block 2 in the corresponding limiting hole 11 is adjusted so that the positioning block 2 can penetrate the hole for positioning when the pole plates 4 are stacked.
[0040] like Figure 2-3 As shown, the peripheral side of the support plate 1 is provided with a plurality of material taking grooves 12 retreating toward the inside of the support plate 1, so that the notches of the material taking grooves 12 are recessed in the peripheral outer edge of the support plate 1. The number of the material taking grooves 12 can be multiple, and the multiple material taking grooves 12 are arranged along the circumference of the support plate 1, so as to clamp the stacked electrode plates 4 in the circumference of the tooling and take out the stacked electrode plates 4 as a whole.
[0041] In order to fix the position of the positioning block 2 in the limiting hole 11, in this embodiment, a fixing hole 13 connected to the limiting hole 11 is provided on the peripheral side of the support plate 1, and a fixing column 3 is provided in the fixing hole 13; the fixing column 3 extends into the limiting hole 11 through the fixing hole 13 and is crimped onto the positioning block 2 to lock the position of the positioning block 2 in the first direction.
[0042] In addition to X-axis positioning and Y-axis positioning, the electrode plate 4 stacking tool of this embodiment also provides Z-axis positioning, so that the electrode plates 4 can be stacked to achieve three-axis positioning and calibration. Figure 4-5 As shown, the positioning block 2 includes a fixing member 22, the fixing member 22 is movably connected to an adjusting member 23, and the adjusting member 23 is provided with an adjusting assembly 24, so that the adjusting member 23 can move relative to the fixing member 22 along a third direction to adjust the spacing between the fixing member 22 and the adjusting member 23 in the third direction. In this embodiment, the third direction is the Z direction shown in the figure, and the third direction, the first direction, and the second direction are perpendicular to each other.
[0043] The adjustment component 24 includes a bolt member 240 and a top screw member 241; the adjustment member 23 is provided with a bolt hole 230 and a top screw hole 231, and the fixing member 22 is provided with a locking hole 220 corresponding to the position of the bolt hole 230; wherein,
[0044] There are multiple bolt holes 230 , which are arranged along the second direction; there are multiple top screw holes 231 , which are arranged along the second direction.
[0045] According to the size of the hole for positioning when the electrode plates 4 are stacked, the top screw member 241 abuts against the fixing member 22 through the top screw hole 231 to adjust the relative position between the adjusting member 23 and the fixing member 22, so that the fixing member 22 and the adjusting member 23 can respectively fit the inner wall of the hole for positioning when the electrode plates 4 are stacked, and the bolt member 240 is screwed into the locking hole 220 through the bolt hole 230 to fix the relative position between the adjusting member 23 and the fixing member 22.
[0046] In order to ensure that the fixing column 3 is tightly connected to the positioning block 2 and to prevent the positioning block 2 from shifting during the stacking of the plates 4, the positioning block 2 may be provided with a mounting hole 25 for the fixing column 3 to penetrate, and the mounting hole 25 is formed on the fixing member 22. The fixing column 3 extends into the limiting hole 11 through the fixing hole 13 and penetrates the fixing member 22 through the mounting hole 25. The fixing column 3 and the fixing hole 13 may be threadedly matched to ensure that the positions of the fixing column 3 and the fixing hole 13 will not shift.
[0047] The working process of the plate stacking tooling of this embodiment is as follows:
[0048] Place the support plate 1 on the workbench with the support surface 10 facing upward. Install the positioning block 2 into the limiting hole 11, with the positioning block 2 facing upward and placed along the second direction. According to the specifications of the pole plate 4, adjust the spacing between the two positioning blocks 2 in the first direction so that the two positioning blocks 2 can respectively fit the inner wall of the hole where the pole plates 4 are positioned when stacked. Install the fixing column 3 so that the fixing column 3 passes through the fixing hole 13 and the mounting hole 25 into the fixing member 22 to lock the position of the positioning block 2. According to the specifications of the pole plate 4, screw the top screw 241 and the bolt member 240 to adjust the relative position between the adjusting member 23 and the fixing member 22 so that the fixing member 22 and the adjusting member 23 can respectively fit the inner wall of the hole where the pole plates 4 are positioned when stacked, and make the circumferential limiting surface 21 of the positioning block 2 respectively fit the inner wall of the hole where the pole plates 4 are positioned when stacked, so as to realize the three-way positioning of the pole plate 4.
[0049] Subsequently, the electrode plates 4 are sequentially passed through the guide surface 20 and placed on the positioning blocks 2, and stacked on the support surface 10. After the electrode plates 4 are stacked, the stacked electrode plates 4 are taken out as a whole by using an external tool and the notch of the material taking trough 12.
[0050] In summary, the embodiment of the utility model provides a tool for stacking pole plates, which uses a positioning block 2 extending along the second direction and the hole structure of the pole plate 4 itself to enable the pole plate 4 to be inserted into the positioning block 2. Moreover, based on the positioning block 2 being able to move along the first direction in the limiting hole 11, the positioning block 2 can fit the inner wall of the hole used for positioning the pole plate 4 when stacking, ensuring that the pole plate 4 is accurately positioned when stacked, and avoiding the problem of misalignment of the pole plate 4 during the stacking process; moreover, the tool for stacking pole plates uses the design of the material extraction trough 12 to remove the stacked pole plates 4 from the tool as a whole, avoiding position deviation of the stacked pole plates 4 when the tool is removed; in addition, the design of the positioning block 2 of the pole plate 4 stacking tool enables positioning and calibration in the third direction, and with the limiting of the support surface 10, the pole plate 4 stacking tool can achieve positioning and calibration in the three directions of XYZ, ensuring that the pole plates 4 are accurately positioned in the three directions when stacked.
[0051] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
