Description

Technical Field

[0001] The present invention relates to the technical field of proton exchange membrane fuel cells, and particularly relates to an electrode plate bonding device and an electrode plate bonding method. Background Art

[0002] A proton exchange membrane fuel cell is a power generation device that directly converts chemical energy existing in fuel and an oxidant into electrical energy. In a typical proton exchange membrane fuel cell, a membrane electrode is generally placed between two conductive electrode plates, and flow guiding grooves are provided on both of the two single electrode plates. The flow guiding grooves are formed on the surface in contact with the membrane electrode by die casting, stamping or mechanical milling, and the number thereof is more than one. The flow guiding grooves inside the electrode plate are both channels for fuel and oxidant to enter the surfaces of the anode and the cathode, and also drainage channels for taking away the water generated during the operation of the battery. The antifreeze flow guiding grooves outside the electrode plate are used to maintain the temperature of the electrode plate and the surface of the membrane electrode from being too high after introducing antifreeze.

[0003] However, the existing electrode plates are bonded by adopting a process edge positioning method. Due to the influence of die cutting and mold forming, etc., deviations and extensions of the process edge and the bonding position are caused, which affects the alignment of the flow channels of the antifreeze circulation cavity during single plate bonding, causes blockage of the flow channels of the cavity, and makes the heat generated during the above battery conversion process unable to be effectively discharged.

[0033] To facilitate the understanding of the embodiments of the present invention, the structure of the present invention will be described in detail below through several specific embodiments.

[0034] According to Figures 1-5 As shown, an electrode plate bonding device is provided in an embodiment of the present invention. The device includes: a substrate 10 for bonding an electrode plate 15 through its upper surface; a positioning rod 142 vertically disposed on the substrate 10 and having one end extending out of the upper surface of the substrate 10 for passing through an electrode hole in the electrode plate 15 to position the electrode plate 15; and an adjustment structure disposed on the substrate 10 for adjusting the position of the electrode plate 15.

[0035] In this regard, the side of the first electrode plate 15 having a diversion groove is brushed with an adhesive. After the electrode hole in the first electrode plate 15 passes through the positioning rod 142, the side of the first electrode plate 15 brushed with the adhesive is placed on the upper surface of the substrate 10 to bond the first electrode plate 15 and the substrate 10, and the antifreeze groove 151 of the first electrode plate 15 is disposed away from the substrate 10; then, after the electrode plate 15 of the second electrode plate 15 passes through the positioning rod 142, the side of the second electrode plate 15 having the antifreeze groove 151 is placed facing the substrate 10, so that the second electrode plate 15 and the electrode plate 15 placed on the substrate 10 in a fitting manner are stacked in sequence. Then, the position of the second electrode plate 15 is adjusted by the adjustment structure so that the two electrode plates 15 are aligned and fitted, and the antifreeze grooves 151 of the two electrode plates 15 are adapted to form an antifreeze groove 151 cavity; then, the above operations are repeated to place the remaining electrode plates 15, thereby improving the bonding and positioning accuracy between the electrode plates 15, ensuring the coincidence degree of the bonding surfaces, improving the compressive capacity of the bonded electrode plates 15, and increasing the yield rate of pressure retention and series leakage of the bonded electrode plates 15.

[0036] Specifically, in this embodiment, the embodiment provides an electrode plate bonding device, which includes: a substrate 10, a positioning rod 142, and an adjusting structure.

[0037] Among them, the upper surface of the substrate 10 is used for bonding the electrode plate 15. Among them, the electrode plate 15 is a single plate electrode, and moreover, the electrode plate 15 can be an anode single plate electrode for a fuel cell, and of course, it can also be a cathode single plate electrode for a fuel cell.

[0038] Moreover, a flow guiding groove is formed on one side of the electrode plate 15, and an antifreeze groove 151 is formed on the other opposite side of the electrode plate 15. Among them, the flow guiding groove is not only a channel for fuel and oxidant to enter the anode and cathode surfaces, but also a drainage channel for taking away the water generated during the operation of the battery. The antifreeze groove 151 is used to maintain the temperature of the electrode plate 15 and the surface of the membrane electrode from being too high after being filled with antifreeze.

[0039] Moreover, in this embodiment, the flow guiding groove and the antifreeze groove 151 can be formed by die casting, stamping or mechanical milling, and the number is more than one. In this embodiment, the manufacturing process for forming the notch is not limited, as long as it meets the requirements of this embodiment.

[0040] In addition, the electrode plate 15 can be made of a metal material or a graphite material (such as: flexible graphite material). In this embodiment, the material of the electrode plate 15 is not limited, as long as it meets the requirements of this embodiment.

[0041] Optionally, in this embodiment, the side of the electrode plate 15 with the flow guiding groove is bonded to the upper surface of the substrate 10.

[0042] Regarding the above-mentioned positioning rod 142, the positioning rod 142 is vertically arranged on the substrate 10. Preferably, one end of the positioning rod 142 is fixed on the upper surface of the substrate 10, and moreover, the other end of the positioning rod 142 extends out of the upper surface of the substrate 10, and the positioning rod 142 is perpendicular to the substrate 10.

[0043] Regarding the above-mentioned adjusting structure, the adjusting structure is also arranged on the substrate 10, and moreover, the adjusting structure is used to adjust the position of the electrode plate 15.

[0044] Specifically, apply adhesive to the side of the first electrode plate 15 where the diversion groove is provided. After the positioning rod 142 passes through the electrode holes in the first electrode plate 15, place the side of the first electrode plate 15 with adhesive applied on the upper surface of the substrate 10 to bond the first electrode plate 15 and the substrate 10, and make the antifreeze groove 151 of the first electrode plate 15 face away from the substrate 10. Then, after passing the electrode plate 15 of the second electrode plate 15 through the positioning rod 142, place the side of the second electrode plate 15 where the antifreeze groove 151 is provided facing the substrate 10, so that the second electrode plate 15 and the electrode plate 15 placed on the substrate 10 in a fitting manner are stacked in sequence. Then, adjust the position of the second electrode plate 15 through the adjusting structure so that the two electrode plates 15 are aligned and fitted, and moreover, the antifreeze grooves 151 of the two electrode plates 15 are adapted to form an antifreeze groove 151 cavity. Then, repeat the above operations to place the remaining electrode plates 15, thereby improving the bonding and positioning accuracy between the electrode plates 15, and moreover, ensuring the coincidence degree of the bonding surfaces, improving the compressive capacity of the electrode plates 15 after bonding, and also increasing the yield rate of pressure holding and series leakage of the electrode plates 15 after bonding.

[0045] In another embodiment, for the above-mentioned adjusting structure, it includes: a moving rod 143 and a driving member. Among them, the moving rod 143 passes through the electrode holes, and moreover, the driving member is arranged on the substrate 10 and the driving member is connected to the moving rod 143, and the driving member drives the moving rod 143 to move for the moving rod 143 to drive the electrode plate 15 to move.

[0046] In this embodiment, the driving member is not limited, and it includes: a threaded hole and a threaded rod 141. Among them, the threaded hole is opened on the moving rod 143. Optionally, the threaded hole is opened at one end of the moving rod 143. Moreover, the threaded rod 141 is perpendicular to the moving rod 143, and moreover, the threaded rod 141 forms a threaded connection with the threaded hole, and the length direction of the threaded rod 141 is parallel to the moving path of the electrode plate 15.

[0047] Specifically, in this embodiment, after sleeving the electrode holes of the electrode plate 15 on the outer periphery of the moving rod 143, by rotating the threaded rod 141, the moving rod 143 can be driven to move along the length direction of the threaded rod 141, so that the moving rod 143 drives the electrode plate 15 to move, that is: the moving rod 143 drives the electrode plate 15 to move.

[0048] Of course, in another embodiment, the driving member can also be a straight rod, and the end of the straight rod is fixed to the end of the moving rod 143, and the moving rod 143 is driven to move by moving the straight rod back and forth.

[0049] Moreover, in another embodiment, the adjustment structure further includes: a driving hole 144 and a moving hole 145. Among them, the driving hole 144 is formed on the substrate 10, and the driving hole 144 is used to place the threaded rod 141 for the threaded rod 141 to rotate around the central axis of the threaded rod 141; the moving hole 145 is formed on the substrate 10, and the moving hole 145 communicates with the driving hole 144. In this embodiment, the moving hole 145 is used to place the moving rod 143, and the moving rod 143 moves freely within the plane where the axial section of the moving hole 145 is located.

[0050] Certainly, in another embodiment, the adjustment structure further includes: an internal thread, which is provided on the inner wall of the driving hole 144, and the internal thread is threadedly connected to the threaded rod 141. In this embodiment, the internal thread has the same thread helix direction as the thread hole formed on the moving rod 143. Through this internal thread, the threaded rod 141 can be limited to prevent the threaded rod 141 from being displaced.

[0051] Certainly, in another embodiment, the adjustment structure can also be arranged as follows: a limiting ring groove is formed on the inner wall of the driving hole 144, and a limiting block 1412 is provided on the threaded rod 141. Among them, the limiting block 1412 rotates around the central axis of the threaded rod 141 within the limiting ring groove and limits the movement of the threaded rod 141 in the length direction of the driving hole 144. In this embodiment, the threaded rod 141 is only threaded at the part in contact with the moving rod 143. Of course, the length of this thread needs to be able to adjust the electrode plate 15. The limiting block 1412 can be set as an annular structure surrounding the outer circumference of the threaded rod 141. Of course, the limiting block 1412 can also be arranged in an arc shape.

[0052] Regarding the power output for driving the rotation of the threaded rod 141, in another embodiment, the adjustment structure further includes: a driving motor. In this embodiment, the driving motor is arranged at the end of the threaded rod 141 away from the thread hole, and the driving motor is used to drive the threaded rod 141 to rotate so that the threaded rod 141 drives the moving rod 143 to move.

[0053] Certainly, the adjustment structure includes: a manual rotating member 1411. Among them, the manual rotating member 1411 is detachably fixed to the end of the threaded rod 141 away from the thread hole. The user only needs to rotate the manual rotating member 1411 to drive the threaded rod 141 to rotate so that the threaded rod 141 drives the moving rod 143 to move.

[0054] In another embodiment, the above-mentioned driving hole 144 is formed on the surface of the substrate 10, and the above-mentioned driving hole 144 is arranged in a notch shape; moreover, the cross-section of the driving hole 144 is arranged in a superior arc shape. In this case, since the driving hole 144 communicates with the moving hole 145, and the threaded rod 141 drives the moving rod 143 to move, therefore, in this embodiment, the moving hole 145 is also arranged in a notch shape. After placing the electrode plate 15, the electrode plate 15 is stacked above the driving hole 144 and the moving hole 145.

[0055] In another embodiment, the number of the adjusting structures is set to one or more; moreover, the adjusting structure is used to adjust the longitudinal position and / or the lateral position of the electrode plate 15.

[0056] For example: in this embodiment, two adjusting structures are provided, that is: two threaded rods 141 and two moving rods 143 are provided, wherein the two threaded rods 141 are vertically arranged and distributed on both sides of the substrate 10. Thus, the longitudinal position and the lateral position of the electrode plate 15 can be adjusted by these two adjusting structures.

[0057] In addition, in another embodiment, the device further includes: a side end plate 12, a pressing plate 11 and a handle 13.

[0058] In this embodiment, the side end plate 12 is detachably fixed to the side of the substrate 10 to be close to the electrode plate 15. One end of the side end plate 12 extends out of the upper surface of the substrate 10, and moreover, the side of the side end plate 12 that is close to the electrode plate 15 is smooth and flat for limiting the electrode plate 15. Therefore, in this embodiment, the side end plate 12 is used to perform secondary alignment and limiting on the stacked plurality of electrode plates 15 to ensure the bonding accuracy between the electrode plates 15.

[0059] The pressing plate 11 is arranged above the substrate 10. The pressing plate 11 is used to press the bonded electrode plates 15, and moreover, the pressing plate 11 is parallel to the substrate 10, and the side of the pressing plate 11 is close to the side of the side end plate 12 that is close to the electrode plate 15.

[0060] In another embodiment, the pressing plate 11 is also provided with fitting holes 146 corresponding one-to-one to the positioning rods 142 and the moving rods 143. The sizes and shapes of the fitting holes 146 are respectively adapted to the sizes and shapes of the corresponding positioning rods 142 or moving rods 143. It helps to limit the pressing plate 11 by the positioning rods 142 or the moving rods 143 during the pressing process, so as to prevent the pressing plate 11 from shifting under the action of pressure and driving the electrode plate 15 to shift, ensuring the positioning and bonding accuracy of the electrode plate 15.

[0061] The handle 13 is arranged on the side of the substrate 10 to facilitate transportation and stabilize the electrode plate bonding device.

[0062] In another embodiment, an electrode plate bonding method is provided. This method is implemented by the above-mentioned electrode plate bonding device. Moreover, this method includes:

[0063] S11: Brush an adhesive on the upper surface of the substrate 10;

[0064] S12: After passing the positioning rod 142 and the moving rod 143 through the electrode holes in the first electrode plate 15, bond the opposite sides of the first electrode plate 15 where the anti-freezing grooves 151 are formed to the surface of the substrate 10 where the adhesive is brushed;

[0065] S13: After passing the electrode holes of the second electrode plate through the positioning rod 142 and the moving rod 143, bond the side of the second electrode plate 15 where the anti-freezing groove 151 is formed to the surface of the first electrode plate 15 where the anti-freezing groove 151 is formed; Adjust the position of the second electrode plate 15 by rotating the threaded rod 141 to drive the moving rod 143, so as to adjust the second electrode plate 15 to a preset position;

[0066] S14: After passing the electrode holes of the third electrode plate through the positioning rod 142 and the moving rod 143, bond the side of the third electrode plate where the anti-freezing groove 151 is formed to the surface of the second electrode plate 15 where the anti-freezing groove 151 is formed; Adjust the position of the third electrode plate 15 by rotating the threaded rod 141 to drive the moving rod 143, so as to adjust the third electrode plate 15 to a preset position;

[0067] S15: Repeat the above S13 - S14 to position and bond a preset number of electrode plates;

[0068] S16: After the preset number of electrode plates 15 are positioned and bonded, install the side end plates 12, and limit these electrode plates 15 through the side end plates 12 to perform positioning again;

[0069] S17: Cover the pressure plate 11 to apply pressure to these electrode plates 15 after positioning, so as to achieve the bonding of the electrode plates 15.

[0070] To better illustrate the structure of the electrode plate bonding device and the electrode plate bonding method in this embodiment, the following combines a specific application example to illustrate the device and method in this embodiment.

[0071] Specifically, according to Figure 1 and 2As shown in the figure, this embodiment provides an electrode plate bonding device for positioning and bonding flexible graphite bipolar plates. The device includes: a substrate 10, positioning rods 142, a pressing plate 11, side end plates 12, two handles 13, and two adjusting structures.

[0072] Among them, the two handles 13 are respectively detachably fixed to the two wide and high surfaces of the substrate 10 through threaded members. Moreover, the side end plate 12 is detachably fixed to the long and high surface of the substrate 10 through threaded members.

[0073] Moreover, the two positioning rods 142 are both vertically arranged on the substrate 10.

[0074] The substrate 10 and the pressing plate 11 are of the same size and shape, and after all the electrode plates are bonded, the substrate 10 and the pressing plate 11 are aligned vertically.

[0075] In addition, each adjusting structure includes a threaded rod 141, a moving rod 143, a driving hole 144, and a moving hole 145. In this embodiment, the two driving holes 144 are vertically arranged and are both provided in the substrate 10. Of course, the two threaded rods 141 are also vertically arranged.

[0076] Moreover, a butterfly nut is provided at the end of each threaded rod 141 far from the moving rod 143. The butterfly nut protrudes outside the substrate 10, and the threaded rod 141 is driven to rotate by rotating the butterfly nut.

[0077] Moreover, the orifice of one driving hole 144 is opened on the wide and high surface of the substrate 10, and the orifice of one driving hole 144 is opened on the long and high surface. Moreover, the two moving rods 143 are both perpendicular to the substrate 10, and a threaded hole is opened at the end of each moving rod 143, and the threaded hole and the end of the corresponding driving rod form a threaded connection.

[0078] During the specific process of bonding the electrode plates, the first step: First, apply the adhesive on the side of the flow guiding groove of the first electrode plate 15. Then, after passing the electrode holes of the first electrode plate 15 through the positioning rods 142 and the moving rods 143, the side of the first electrode plate 15 with the adhesive applied is fixed to the upper surface of the substrate 10. Among them, the first electrode plate 15 is the cathode single plate of the cathode oxidant or the anode single plate for the anode fuel in the electrode plates 15.

[0079] The second step: Align the anti-freezing groove 151 of the second electrode plate 15 with the anti-freezing groove 151 of the first electrode plate 15 already bonded to the substrate 10. After passing the second electrode plate 15 through the positioning rods 142 and the moving rods 143, stack the second electrode plate 15 on the first electrode plate 15.

[0080] Step 3: By adjusting the wing nut, drive the two threaded rods 141 to rotate, thereby driving the corresponding moving rods 143 to adjust the longitudinal and lateral positions of the second single-pole plate, so that the second single-pole plate is aligned with the first electrode plate 15 already adhered to the substrate 10;

[0081] Step 4: Repeat the above Step 2 and Step 3 to stack the remaining electrode plates 15 on the substrate 10 in sequence;

[0082] Step 5: Fix the side end plate 12 to the long and high surfaces of the substrate 10 with screws to realign and limit the stacked electrode plates 15 again, so as to ensure the accuracy of the alignment and bonding of each electrode plate 15;

[0083] Step 6: Cover the pressure plate 11 to apply pressure to the stacked electrode plates 15, thereby completing the bonding and positioning of the electrode plates 15.

[0084] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by orientation words such as "front, back, up, down, left, right", "horizontal, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the orientation or positional relationships shown in the drawings. These orientation words are only for the convenience of describing the present invention and simplifying the description. Without contrary statements, these orientation words do not indicate and imply that the devices or elements referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the protection scope of the present invention; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0085] For the convenience of description, spatial relative terms such as "above...", "above...", "on the upper surface of...", "above" can be used here to describe the spatial positional relationship between a device or feature shown in the figure and other devices or features. It should be understood that the spatial relative terms are intended to include different orientations in use or operation in addition to the orientation described in the figure for the device. For example, if the device in the drawing is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "beneath other devices or structures" afterwards. Thus, the exemplary term "above..." can include both orientations of "above..." and "below...".
