Description

Technical Field

[0001] The present invention relates to the field of fuel cells, and in particular to a feeding bracket and bipolar plate sealing pretreatment equipment. Background Art

[0002] In order to ensure the gas-tightness of the fuel cell stack, the bipolar plate will be pre-treated. The pre-treatment includes applying glue in the plate sealing groove and pasting the plate sealing gasket in the sealing groove. In the related art, the pasting method of the plate sealing gasket can be divided into two types according to the pressing operation. In the first method, the plate sealing gasket with a fixed position is pressed as the mobile end into the bipolar plate sealing groove with glue at the fixed end. In the second method, the bipolar plate with glue applied is used as the mobile end and pressed on the plate sealing gasket precisely positioned at the fixed end.

[0003] Among them, the first method has very high requirements for the positioning accuracy of the plate gasket, and the plate gasket is most likely to deviate from the sealing groove. The second method can maintain a high accuracy because the plate gasket is used as a fixed end, greatly reducing the deviation of the plate gasket from the sealing groove.

[0004] However, in the second method, during the formal production process, the feeding state of the plate gasket will affect the pasting of the plate gasket, especially causing the plate gasket to deviate from the sealing groove. Among them, the factor that determines the feeding state of the plate gasket is mainly the state of the plate gasket on the feeding jig tray. The plate gasket is manually laid on the feeding jig tray at the production site. There are many pulling actions on the plate gasket during the laying process, especially when the incoming plate gasket is too large or too small. The pulling action will cause a large difference in the initial state of the plate gasket in the feeding jig tray. Secondly, there is a lot of manual intervention in the process of laying the plate gasket, and there is a risk of deformation, foreign matter, and dirt on the plate gasket. Summary of the invention

[0029] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0030] Reference below Figure 1 and Figure 2A loading bracket and a bipolar plate sealing pretreatment device according to an embodiment of the present invention are described.

[0031] like Figure 1 and Figure 2 As shown, the loading bracket of the embodiment of the present invention includes a bracket body 1 and a grabbing portion 3.

[0032] The top surface of the support body 1 is used to carry the plate sealing gasket 2. The gripping portion 3 is arranged on the side surface and / or the bottom surface of the support body 1.

[0033] Specifically, Figure 1 and Figure 2 As shown, the pole plate sealing gasket 2 is used to be assembled on the end face of the bipolar plate 6. The end face of the bipolar plate 6 is provided with a sealing groove that is adapted to the shape and size of the pole plate sealing gasket 2. The pole plate sealing gasket 2 is embedded in the sealing groove. More preferably, glue is sprayed in the sealing groove of the bipolar plate 6 so that the pole plate sealing gasket 2 is bonded and connected to the sealing groove.

[0034] The bracket body 1 is used for horizontal placement, and the top surface of the bracket body 1 is used to support the pole plate sealing gasket 2. Preferably, the shape and size of at least part of the bracket body 1 are adapted to the shape and size of the pole plate sealing gasket 2, so that the top surface of the bracket body 1 can support the pole plate sealing gasket 2. At the same time, by observing the degree of adaptation between the pole plate sealing gasket 2 and the bracket body 1, it is judged whether the model of the pole plate sealing gasket 2 meets the load-bearing requirements of the bracket body 1. For example, the outer periphery or one end of the pole plate sealing gasket 2 exceeds the edge of the bracket body 1. At this time, the pole plate sealing gasket 2 does not meet the load-bearing requirements of the bracket body 1 and needs to be discarded.

[0035] In addition, after the top surface of the support body 1 carries the plate gasket 2 , by observing whether the plate gasket 2 has a protrusion, it is also possible to determine whether foreign matter is attached to the plate gasket 2 , so as to ensure the cleanliness of the plate gasket 2 .

[0036] The side and / or bottom surface of the bracket body 1 is provided with a gripping portion 3, and the operator moves the loading bracket through the gripping portion 3, and then moves the plate gasket 2 to load the plate gasket 2 to the device. It should be noted that the gripping portion 3 can be a component connected to the bracket body 1, such as a support ear, a gripping piece, a handle, etc., the gripping portion 3 can also be a protrusion provided on the bracket body 1, such as a boss or a step, etc. The gripping portion 3 can also be a part of the outer wall surface of the bracket body 1, such as the bottom surface of the gripping portion 3, or the outer peripheral surface of the gripping portion 3 forms a plurality of gripping portions 3 arranged at intervals along its circumference.

[0037] The loading bracket of the embodiment of the present invention carries the pole plate sealing gasket through the bracket body, and moves the loading bracket through the grabbing part on the bracket body, so that the pole plate sealing gasket is carried and moved by the loading bracket. Assembling the pole plate sealing gasket through the loading bracket can ensure the consistency of the feeding state of the pole plate sealing gasket and the uniformity of glue distribution in the bipolar plate sealing groove, reduce manual intervention, ensure the cleanliness of the pole plate sealing gasket, avoid deformation of the pole plate sealing gasket, and greatly improve the assembly efficiency. It is also possible to inspect the size of the pole plate sealing gasket and the presence of foreign matter.

[0038] In some embodiments, the top surface of the support body 1 is flush. In other words, the top surface of the support body 1 is a plane, preferably a smooth plane. The plate gasket 2 is disposed behind the top surface of the support body 1. By observing whether the plate gasket 2 is partially raised, it can be determined whether there is foreign matter on the plate gasket 2.

[0039] In some embodiments, the bracket body 1 includes an attachment layer, a support layer and an isolation layer, the support layer is arranged between the attachment layer and the isolation layer, the attachment layer forms the top surface of the bracket body 1, the isolation layer forms the bottom surface of the bracket body 1, and the grasping portion 3 is arranged on the side of the bracket body 1.

[0040] Specifically, during use, a plurality of loading brackets carrying the electrode plate sealing gaskets 2 can be stacked together to facilitate overall movement and reduce occupied space.

[0041] The support body 1 comprises an attachment layer, a support layer and an isolation layer which are sequentially arranged and fixedly connected from top to bottom, and the attachment layer, the support layer and the isolation layer are all arranged horizontally.

[0042] The attachment layer forms the top surface of the support body 1 for carrying and attaching the plate sealing gasket 2 to prevent the plate sealing gasket 2 from sliding on the support body 1 or even falling off.

[0043] The isolation layer forms the bottom surface of the bracket body 1. When multiple loading brackets carrying the plate sealing gaskets 2 are stacked, the isolation layer abuts against the plate sealing gaskets 2 on the lower loading bracket, which can prevent the plate sealing gaskets 2 from sticking to the upper bracket body 1 and prevent the position of the plate sealing gaskets 2 from migrating during the use process.

[0044] The support layer is connected between the attachment layer and the isolation layer, and plays a role in supporting the attachment layer and the isolation layer, and further supports the plate sealing gasket 2 to prevent the loading bracket from deforming.

[0045] The gripping portion 3 is disposed on a side of the support body 1 , and preferably, the gripping portion 3 is disposed on a side of the support layer.

[0046] In some embodiments, at least a portion of the support layer is a magnetic attraction portion.

[0047] Specifically, the support layer uses magnetic material to form a magnetic part as a whole. When multiple loading brackets carrying the pole plate sealing gasket 2 are stacked, there is a magnetic force between the support layers of two adjacent loading brackets to ensure that the two adjacent loading brackets are stacked to avoid tilting or sliding, thereby ensuring the consistency and stability of multiple loading brackets when they are stacked.

[0048] It can be understood that the support layer is not limited to forming the magnetic attraction part as a whole. In other embodiments, a plurality of magnetic blocks are provided on the top and bottom of the support layer, and the magnetic blocks form the magnetic attraction part. On two adjacent loading brackets, the plurality of magnetic blocks at the bottom of the upper loading bracket and the plurality of magnetic blocks at the top of the lower loading bracket are arranged one by one correspondingly to form a magnetic attraction force.

[0049] In some embodiments, both the attachment layer and the isolation layer are rubber layers, and the surface roughness of the attachment layer is smaller than the surface roughness of the isolation layer.

[0050] Specifically, the adhesive layer is a rubber layer. In other words, the adhesive layer is made of rubber material, so that the adhesive layer can form an adhesive effect with the plate gasket 2 due to the effect of electrostatic attraction, and the plate gasket 2 can be separated from the adhesive layer when subjected to external force.

[0051] The isolation layer is a rubber layer. In other words, the isolation layer is made of rubber material. The isolation layer is a non-conductive rubber material and is used to conduct the charge generated by the friction of the plate sealing gasket 2 to ensure the electrostatic attraction between the attachment layer and the plate sealing gasket 2 .

[0052] Meanwhile, the surface roughness of the isolation layer is greater than that of the attachment layer, so that the adhesion to the electrode plate sealing gasket 2 is reduced by the greater surface roughness.

[0053] This prevents the lower electrode plate sealing gasket 2 from shifting as the upper loading bracket moves during stacking.

[0054] In some embodiments, the gripping portion 3 is a lug.

[0055] like Figure 1 As shown, the gripping portion 3 is preferably an annular ear having a notch so that the annular ear forms two ends along its circumference, and both ends of the annular ear are connected to the side surface of the support layer.

[0056] There are preferably two gripping parts 3, and the two gripping parts 3 are symmetrically arranged along the center line of the loading bracket.

[0057] The operator can smoothly move the loading bracket by holding the two gripping parts 3, and ensure that the loading bracket is level when the loading bracket carries the plate sealing gasket 2, so as to avoid the loading bracket tilting and causing the plate sealing gasket 2 to fall off.

[0058] In some embodiments, the bracket body 1 is provided with a plurality of through holes, and the electrode plate sealing gasket 2 is provided with a plurality of dielectric holes, and the plurality of through holes are used to be arranged in a one-to-one correspondence with the plurality of dielectric holes.

[0059] Specifically, the bracket body 1 is provided with a plurality of through holes, which penetrate the bracket body 1 in a vertical direction; the pole plate sealing gasket 2 is provided with a plurality of dielectric holes, which penetrate the pole plate sealing gasket 2 in a vertical direction; when the pole plate sealing gasket 2 is placed on the bracket body 1, the plurality of through holes and the plurality of dielectric holes are arranged one by one.

[0060] It should be noted that the bipolar plate 6 is provided with a plurality of chamber inlets and outlets. When the plate sealing gasket 2 is assembled onto the bipolar plate 6 , the plurality of medium holes are provided in one-to-one correspondence with the plurality of chamber inlets and outlets.

[0061] In some embodiments, the multiple through holes include at least two first through holes 11, at least two second through holes 12 and at least two third through holes 13, the multiple medium holes include at least two hydrogen holes, at least two air holes and at least two water holes, the at least two first through holes 11 are used to be arranged in a one-to-one correspondence with the at least two water holes, the at least two second through holes 12 are used to be arranged in a one-to-one correspondence with the at least two air holes, and the at least two third through holes 13 are used to be arranged in a one-to-one correspondence with the at least two hydrogen holes.

[0062] like Figure 1 As shown, the multiple through holes include at least two first through holes 11, at least two second through holes 12 and at least two third through holes 13, the multiple medium holes include at least two hydrogen holes, at least two air holes and at least two water holes, the at least two first through holes 11 are used to be arranged in a one-to-one correspondence with the at least two water holes, the at least two second through holes 12 are used to be arranged in a one-to-one correspondence with the at least two air holes, and the at least two third through holes 13 are used to be arranged in a one-to-one correspondence with the at least two hydrogen holes.

[0063] The chamber inlet and outlet of the bipolar plate 6 include a hydrogen chamber inlet, a hydrogen chamber outlet, a cavity inlet, a cavity outlet, a water chamber inlet and a water chamber outlet. At least one hydrogen hole is arranged corresponding to the hydrogen chamber inlet for hydrogen to enter the hydrogen chamber of the bipolar plate 6. At least one hydrogen hole is arranged corresponding to the hydrogen chamber outlet for hydrogen to be discharged from the hydrogen chamber of the bipolar plate 6. At least one air hole is arranged corresponding to the cavity inlet for air to enter the cavity of the bipolar plate 6. At least one air hole is arranged corresponding to the cavity outlet for air to be discharged from the cavity of the bipolar plate 6. At least one water hole is arranged corresponding to the water chamber inlet for water to enter the water chamber of the bipolar plate 6. At least one water hole is arranged corresponding to the water chamber outlet for water to be discharged from the water chamber of the bipolar plate 6.

[0064] Preferably, the water cavity inlet and the water cavity outlet of the bipolar plate 6 are both set to three, so the first through hole 11 is set to six, the cavity inlet and the cavity outlet of the bipolar plate 6 are both set to one, so the second through hole 12 is set to two, and the hydrogen cavity inlet and the hydrogen cavity outlet of the bipolar plate 6 are both set to one, so the third through hole 13 is set to two.

[0065] It should be noted that the shapes of the first through hole 11, the second through hole 12 and the third through hole 13 are adapted to the corresponding hydrogen chamber inlet, hydrogen chamber outlet, cavity inlet, cavity outlet, water chamber inlet and water chamber outlet, and can be rectangular, circular, elliptical or the like or irregular shapes. The shape of the bracket body 1 is not limited and can be rectangular, circular, elliptical or the like or irregular shapes.

[0066] like Figure 1 and Figure 2 As shown, the bipolar plate sealing pretreatment equipment according to the embodiment of the present invention includes a loading bracket, a loading fixture plate 4 and a lifting device 5.

[0067] The loading bracket is a loading bracket of an embodiment of the present invention. A receiving groove is provided on the top surface of the loading fixture disk 4, and the top surface of the loading fixture disk 4 is used to set the bipolar plate 6, and the receiving groove is used to set the loading bracket and the plate sealing gasket 2 carried by the loading bracket, and a plurality of lifting channels 41 are provided on the bottom surface of the receiving groove. The lifting device 5 has a plurality of lifting parts 51, and the plurality of lifting parts 51 are arranged one by one with the plurality of lifting channels 41, and the lifting parts 51 can move in the vertical direction relative to the lifting channels 41 to abut the loading bracket and drive the loading bracket to move in the vertical direction relative to the loading fixture disk 4.

[0068] Specifically, Figure 1 and Figure 2 As shown, a receiving groove is provided in the middle of the top surface of the loading jig plate 4, and the top surface of the loading jig plate 4 is used to carry and set the bipolar plate 6. The bottom surface of the bipolar plate 6 is provided with a sealing groove, and the sealing groove and the receiving groove are arranged opposite to each other in the vertical direction. The receiving groove is used to carry and set the loading bracket, and the loading bracket is provided with a plate sealing gasket 2, and the plate sealing gasket 2 is arranged opposite to the sealing groove in the vertical direction. Preferably, the stacked loading brackets carrying the plate sealing gaskets 2 are assembled into the receiving groove in the loading jig plate by manual or equipment manipulator.

[0069] The bottom surface of the accommodating groove is provided with a lifting channel 41 arranged along the vertical direction, and there are multiple lifting channels 41. A lifting device 5 is provided under the loading jig plate 4. The lifting device 5 can move along the vertical direction relative to the loading jig plate 4. The top of the lifting device 5 has multiple lifting parts 51. The multiple lifting parts 51 are arranged in a one-to-one correspondence with the multiple lifting channels 41. The lifting parts 51 are inserted into the corresponding lifting channels 41 at least when the lifting device 5 is lifting.

[0070] The bipolar plate sealing pretreatment equipment of the embodiment of the present invention receives materials in the form of "feeding bracket-polar plate sealing gasket 2-feeding bracket-polar plate sealing gasket 2...". The lifting device 5 lifts the feeding bracket provided with the polar plate sealing gasket 2 away from the feeding fixture plate 4. The feeding bracket has magnetism and will firmly adsorb the lifting device 5, and rise synchronously with the lifting device 5 without slipping. The polar plate sealing gasket 2 rises with the feeding bracket and will contact the bipolar plate 6 that has been fixed and glued in advance. As the lifting device 5 rises further, the feeding bracket further squeezes the polar plate sealing gasket 2. The pressure on the polar plate sealing gasket 2 is transmitted to the bipolar plate 6, promoting the uniform distribution of glue in the sealing groove. After the bipolar plate 6 with the polar plate sealing gasket 2 is pasted, it flows to the next station. The feeding bracket returns to the bottom of the feeding fixture plate 4 again as the lifting device 5 descends, and is unloaded and leaves together with the feeding fixture plate 4. 511

[0071] The bipolar plate sealing pretreatment equipment of the embodiment of the present invention carries the polar plate and the loading bracket at the same time through the loading fixture disk, and the lifting device lifts the loading bracket in the accommodating groove so that the polar plate sealing gasket on the loading bracket can be assembled into the sealing groove of the polar plate, so as to ensure the consistency of the loading state of the polar plate sealing gasket and the uniformity of the glue distribution in the bipolar plate sealing groove, reduce manual intervention, ensure the cleanliness of the polar plate sealing gasket, avoid deformation of the polar plate sealing gasket, and greatly improve the assembly efficiency, and can also inspect the size of the polar plate sealing gasket and the foreign matter situation.

[0072] In some embodiments, the bipolar plate sealing pretreatment equipment of the embodiment of the present invention also includes a manipulator, which is used to move the bipolar plate 6 to and out of the top surface of the loading jig tray 4, and to limit the position of the bipolar plate 6 when the bipolar plate 6 is located on the top of the loading jig tray 4.

[0073] Specifically, the manipulator can be selected as a suction cup manipulator, which can absorb and release the bipolar plate 6 and can drive the bipolar plate 6 to move. During the assembly process, the suction cup manipulator first absorbs and obtains the bipolar plate 6 to be assembled, and then moves the bipolar plate 6 to be assembled to the top surface of the loading jig tray 4. After the bipolar plate 6 is moved to the top surface of the loading jig tray 4, the suction cup manipulator does not release the bipolar plate 6, but continues to absorb the bipolar plate 6 to be assembled, so as to limit the position of the bipolar plate 6 relative to the top surface of the loading jig tray 4, avoid horizontal movement of the bipolar plate 6, ensure that the sealing groove of the bipolar plate 6 and the plate sealing gasket 2 on the loading bracket are arranged relative to each other in the vertical direction, and also avoid the bipolar plate 6 from moving up during the jacking assembly process, affecting the assembly effect. After the bipolar plate 6 and the plate sealing gasket are assembled, the suction cup manipulator moves the assembled bipolar plate 6 out of the top surface of the loading jig tray 4 and moves it to the next station.

[0074] It should be noted that the bipolar plate sealing pretreatment equipment of the embodiment of the present invention moves the bipolar plate 6 by a manipulator, so during the assembly process, the bipolar plate 6 serves as the moving end and the plate sealing gasket 2 serves as the fixed end.

[0075] It will be appreciated that the bipolar plates are not limited to being moved by a robot.
