Description

Technical Field

[0001] This utility model belongs to the technical field of energy storage battery manufacturing and testing equipment, and in particular, it relates to an integrated device for pressing and airtightness testing. Background Technology

[0002] Flow batteries, as a novel battery technology, have garnered widespread attention due to their advantages such as high efficiency, safety, reliability, long cycle life, and flexible structural design. Currently, most flow batteries employ a single-cell multilayer structure, which mainly includes positive electrode material, negative electrode material, bipolar plates, a separator, a positive electrode frame, and a negative electrode frame. During the assembly of flow batteries, the electrode frame and the separator (such as an ion exchange membrane) generally need to be prefabricated and connected. To ensure both the shape and position requirements of these two prefabricated materials and the uniformity and sealing of the ultra-thin connecting material, adhesive is typically used as an intermediate connecting material to bond the electrode frame and separator. The prefabricated electrode frame and separator are then subjected to airtightness testing to verify the sealing effect. Currently, a pressing device is typically used to bond the electrode frame and separator, followed by an airtightness testing device to verify the airtightness of the prefabricated electrode frame and separator. Since the pressing device and the airtightness testing device are two independent devices, the pre-fabricated electrode frame and separator in the pressing device can only be manually transferred to the airtightness testing device in order to perform airtightness testing on the pre-fabricated electrode frame and separator, which reduces the production efficiency of flow batteries.

[0043] Please refer to the following: Figures 1 to 9 The integrated pressing and airtightness testing device provided in this embodiment of the present invention will now be described. Please refer to the following for further details. Figure 1 , Figure 3 and Figure 5The integrated pressing and airtightness testing device provided in this embodiment includes a carrier 1, a pressing component 2, a locking assembly 3, a sealing assembly 4, and an airtightness testing assembly 5. The carrier 1 is provided with a limiting platform 13 for supporting and limiting the electrode frame 8. The pressing component 2 is used to press the diaphragm 9 onto the electrode frame 8, which is glued on the limiting platform 13. The locking assembly 3 is used to lock the pressing component 2 onto the carrier 1. The sealing assembly 4 is disposed between the pressing component 2 and the carrier 1, and is arranged around the limiting platform 13. When the locking assembly 3 locks the pressing component 2 onto the carrier 1, the pressing component 2 presses the diaphragm 9 onto the electrode frame 8, which is glued on the limiting platform 13. At the same time, the sealing assembly 4 disposed between the pressing component 2 and the carrier 1 will generate a predetermined compression amount, so that the carrier 1, the pre-bonded electrode frame 8, and the diaphragm 9 can form a sealed airtightness testing space. The carrier 1 is provided with an air inlet channel 6 communicating with the gas measurement space, and the pressing component 2 is provided with an air outlet channel 23. The air tightness testing assembly 5 includes a gas pipe connector 51 connected to the air inlet channel 6 and a guide pipe 52 connecting the gas pipe connector 51 to the gas measurement equipment. It should be noted that the air inlet channel 6 includes a connecting hole 61, an air inlet 62, and an air passage 63 connecting the connecting hole 61 and the air inlet 62. The gas pipe connector 51 is connected to the connecting hole 61 by means of threaded connection, plug-in connection, or flange connection. The air outlet channel 23 includes, but is not limited to, an air outlet provided on the pressing component 2. The diaphragm 9 may be, but is not limited to, a proton exchange membrane.

[0044] The main working process of the integrated pressing and airtightness testing device provided in this utility model embodiment is as follows: First, the electrode frame 8 is placed and confined on the limiting platform 13 of the carrier 1. Adhesive is applied to the dispensing area of ​​the electrode frame 8 using a dispensing device. Then, the diaphragm 9 is placed on the dispensed electrode frame 8. Next, the pressing component 2 is placed on the carrier 1 and locked onto the carrier 1 by the locking component 3. At this time, the pressing component 2 presses the diaphragm 9 onto the dispensed electrode frame 8 on the limiting platform 13 to form a pre-bonded electrode frame 8 and diaphragm 9. At the same time, the sealing component 4 located between the pressing component 2 and the carrier 1 will generate a predetermined compression amount, so that the carrier 1 and the pre-bonded electrode frame 8 and diaphragm 9 form a circumferential seal and enclose a sealed air measurement space. After the electrode frame 8 and diaphragm 9 are bonded, the air circuit of the air measurement device is connected through the air pipe connector 51. The airtightness of the pre-bonded electrode frame 8 and diaphragm 9 is tested by the pressure drop method. If the pre-bonded electrode frame 8 and diaphragm 9 are well-sealed, gas will not leak into the space formed by the pressing component 2 and the pre-bonded electrode frame 8 and diaphragm 9. Therefore, the air pressure in the sealed gas measurement space formed by the carrier component 1 and the pre-bonded electrode frame 8 and diaphragm 9 will not decrease, indicating that the pre-bonded electrode frame 8 and diaphragm 9 are well-sealed. If the pre-bonded electrode frame 8 and diaphragm 9 are poorly sealed, gas will leak into the space formed by the pressing component 2 and the pre-bonded electrode frame 8 and diaphragm 9, and flow out through the gas outlet channel 23 on the pressing component 2. This will cause a significant decrease in air pressure in the sealed gas measurement space formed by the carrier component 1 and the pre-bonded electrode frame 8 and diaphragm 9, indicating that the pre-bonded electrode frame 8 and diaphragm 9 are poorly-sealed. Thus, the integrated pressing and airtightness testing device provided in this embodiment of the present invention can directly test the airtightness of the prefabricated electrode frame 8 and diaphragm 9 after pressing and bonding the electrode frame 8 and diaphragm 9 without transferring the prefabricated electrode frame 8 and diaphragm 9, thereby reducing the labor intensity of workers, improving the production efficiency of flow batteries, and reducing the production cost of flow batteries.

[0045] Compared with the prior art, the integrated pressing and airtightness testing device provided in this embodiment of the utility model has a limiting platform 13 set on the carrier 1. After the electrode frame 8 is placed and limited on the limiting platform 13, the pressing component 2 only needs to be locked to the carrier 1 by the locking component 3. The pressing component 2 presses the diaphragm 9 onto the glued electrode frame 8 to form a pre-bonded electrode frame 8 and diaphragm 9. At the same time, the sealing component 4 located between the pressing component 2 and the carrier 1 will generate a predetermined compression amount, so that the carrier 1 and the pre-bonded electrode frame 8 and diaphragm 9 form a circumferential seal and enclose a sealed air measurement space. By connecting to the air circuit of the air measurement equipment through the air pipe connector 51, the airtightness test of the pre-bonded electrode frame 8 and diaphragm 9 can be conveniently performed. Thus, the integrated pressing and airtightness testing device provided in this embodiment of the present invention can directly test the airtightness of the prefabricated electrode frame 8 and diaphragm 9 after pressing and bonding the electrode frame 8 and diaphragm 9 without transferring the prefabricated electrode frame 8 and diaphragm 9, thereby reducing the labor intensity of workers, improving the production efficiency of flow batteries, and reducing the production cost of flow batteries.

[0046] Please refer to the following: Figure 1 , Figure 2 and Figure 4 In some embodiments, the carrier 1 includes a lower frame pad 11 and a first sealing step 12. A limiting platform 13 is disposed on the lower frame pad 11, and the first sealing step 12 is disposed on the outer periphery of the lower frame pad 11, surrounding the limiting platform 13. An air inlet 62 is disposed on the limiting platform 13, and a connecting hole 61 is disposed on the side of the lower frame pad 11. The pressing component 2 includes an upper frame pressing plate 21 and a second sealing step 22. The upper frame pressing plate 21 can cooperate with the limiting platform 13 to press and bond the electrode frame 8 and the diaphragm 9. The second sealing step 22 is disposed on the outer periphery of the upper frame pressing plate 21, and the second sealing step 22 is correspondingly disposed to the first sealing step 12. An air outlet channel 23 is disposed on the upper frame pressing plate 21. A sealing component 4 can be disposed on the first sealing step 12, or it can be disposed on the second sealing step 22, or it can be disposed on both the first sealing step 12 and the second sealing step 22 simultaneously. During the process of locking the pressing component 2 to the carrier component 1, the locking assembly 3 compresses the sealing assembly 4 through the first sealing step 12 and the second sealing step 22. While the pressing component 2 presses the diaphragm 9 onto the glued electrode frame 8 to form a pre-bonded electrode frame 8 and diaphragm 9, the sealing assembly 4 between the first sealing step 12 and the second sealing step 22 generates a predetermined amount of compression. This causes the carrier component 1 and the pre-bonded electrode frame 8 and diaphragm 9 to form a circumferential seal, enclosing a sealed gas measurement space. Under the compression action of the first sealing step 12 and the second sealing step 22, the sealing assembly 4 can improve the circumferential sealing performance of the carrier component 1 and the pre-bonded electrode frame 8 and diaphragm 9, which is beneficial to improving the accuracy of the gas tightness test of the pre-bonded electrode frame 8 and diaphragm 9.

[0047] Please refer to the following: Figure 1 , Figure 3 and Figure 5 In some embodiments, the sealing assembly 4 includes a first annular sealing gasket 41 and a second annular sealing gasket 42. The first annular sealing gasket 41 is disposed on the first sealing step 12, and the second annular sealing gasket 42 is disposed on the second sealing step 22. During the process of locking the pressing member 2 to the carrier member 1, the locking assembly 3 compresses the first annular sealing gasket 41 and the second annular sealing gasket 42, which are in close contact, through the first sealing step 12 and the second sealing step 22. While the pressing member 2 presses the diaphragm 9 onto the glued electrode frame 8 to form a pre-bonded electrode frame 8 and diaphragm 9, the first annular sealing gasket 41 and the second annular sealing gasket 42 between the first sealing step 12 and the second sealing step 22 will generate a predetermined amount of compression. This can further improve the circumferential sealing performance of the carrier member 1 and the pre-bonded electrode frame 8 and diaphragm 9, which is beneficial to improving the accuracy of the airtightness test of the pre-bonded electrode frame 8 and diaphragm 9.

[0048] Please refer to the following: Figure 1 , Figure 2 and Figure 4 In some embodiments, the lower frame pad 11 is provided with at least two first lug structures 14, and the upper frame pressure plate 21 is provided with second lug structures 24 corresponding to the positions of the first lug structures 14. Each first lug structure 14 and the corresponding second lug structure 24 are locked together by a locking assembly 3. By providing first lug structures 14 on the lower frame pad 11 and second lug structures 24 corresponding to the positions of the first lug structures 14 on the upper frame pressure plate 21, it is convenient to pick up the lower frame pad 11 and the upper frame pressure plate 21, and it is convenient to lock the lower frame pad 11 and the upper frame pressure plate 21 together by the locking assembly 3, which can better achieve the pre-fabrication bonding between the diaphragm 9 and the dispensing electrode frame 8. It should be noted that when the number of first lug structure 14 and second lug structure 24 is set to multiple, the spacing between two adjacent first lug structures 14 is approximately equal, and the spacing between two adjacent second lug structures 24 is approximately equal, so as to improve the balance of force on the frame lower pad 11 and the frame upper pressure plate 21, which is beneficial to improve the flatness and uniformity of the pressing and bonding between the frame upper pressure plate 21 and the frame lower pad 11.

[0049] Please refer to the following: Figure 1 , Figure 3 , Figure 5 and Figure 7In some embodiments, the first lug structure 14 is provided with a first positioning hole 15, and the second lug structure 24 is provided with a second positioning hole 25 corresponding to the first positioning hole 15. The locking assembly 3 includes a locking head 31 capable of abutting against the upper pressure plate 21 of the frame, a locking screw 32 connected to the locking head 31, and a locking handle 33 connected to the locking head 31 to drive the locking head 31 to rotate. The first positioning hole 15 is an internal threaded hole that is threadedly engaged with the locking screw 32. After the locking screw 32 passes through the second positioning hole 25 and is threadedly connected to the first positioning hole 15, by rotating the locking handle 33, the locking handle 33 drives the locking head 31 to rotate. The locking screw 32, which rotates coaxially with the locking head 31, locks each first lug structure 14 and the corresponding second lug structure 24 under the threaded engagement of the first positioning hole 15 with internal threads, so as to conveniently and quickly realize the locking connection between the lower pad 11 of the frame and the upper pressure plate 21 of the frame. It should be noted that the number of locking components 3 is consistent with the number of the first lug structure 14 and / or the second lug structure 24.

[0050] Please refer to the following: Figure 1 In some embodiments, when the locking handle 33 drives the locking head 31 to rotate, the external thread of the locking screw 32 engages with the internal thread of the first positioning hole 15, which can drive the upper pressure plate 21 and the lower pad plate 11 of the frame to press the pre-bonded electrode frame 8 and diaphragm 9 together, so that the pre-bonded electrode frame 8 and diaphragm 9 can be pressed together during the gradual application of pressure, which is beneficial to improving the pressing effect of the electrode frame 8 and diaphragm 9.

[0051] In some embodiments, the amount of compression of the electrode frame 8 and the diaphragm 9 by the pressing member 2 and the carrier member 1 is equal to the amount of compression of the sealing component 4. By controlling the amount of compression of the sealing component 4, the amount of compression of the electrode frame 8 and the diaphragm 9 by the pressing member 2 and the carrier member 1 can be gradually adjusted, so as to avoid over-compression or under-compression of the electrode frame 8 and the diaphragm 9, which would reduce the compression effect of the electrode frame 8 and the diaphragm 9.

[0052] Please refer to the following: Figure 1 , Figure 2 and Figure 9 In some embodiments, the carrier 1 is provided with a relief structure 16 corresponding to the protrusion of the electrode frame 8. The relief structure 16 can avoid the protrusion of the electrode frame 8, improve the flatness of the adhesive area on the electrode frame 8, and thus improve the pressing and bonding effect of the electrode frame 8 and the diaphragm 9. The carrier 1 is provided with a support structure 17 corresponding to the recess of the electrode frame 8. The support structure 17 can support and strengthen the recess of the electrode frame 8, which helps to prevent the adhesive area on the electrode frame 8 from deforming under stress during the pressing process, thereby improving the pressing and bonding effect of the electrode frame 8 and the diaphragm 9.

[0053] Please refer to the following: Figure 4 , Figure 5 and Figure 6 In some embodiments, the pressing member 2 is provided with a toothed structure 26 corresponding to the bonding area 10 of the electrode frame 8 and / or the diaphragm 9. The toothed structure 26 applies pressure to the bonding area 10 of the electrode frame 8 and / or the diaphragm 9, which can improve the bonding strength of the bonding area 10 of the electrode frame 8 and / or the diaphragm 9, thereby enhancing the bonding firmness of the electrode frame 8 and / or the diaphragm 9.

[0054] Please refer to the following: Figure 8 and Figure 9 In some embodiments, the carrier 1 is provided with a limiting / correcting structure 7. The limiting / correcting structure 7 can position the electrode frame 8 on the limiting platform 13 according to the predetermined shape and position requirements, so as to ensure the shape and position requirements of the electrode frame 8 during the pressing process, thereby effectively ensuring the sealing effect between the pre-bonded electrode frame 8 and the diaphragm 9.

[0055] Please refer to the following: Figure 8 and Figure 9 In some embodiments, the limiting / correcting structure 7 includes multiple limiting holes and slots 71 provided on the carrier 1, limiting members 72 movably disposed in the corresponding limiting holes and slots 71, and locking members 73 locking each limiting member 72 in the corresponding limiting holes and slots 71. The multiple limiting members 72 are provided one-to-one with the multiple limiting holes and slots 71. By moving and adjusting the position of the corresponding limiting member 72 in each limiting hole and slot 71, each limiting member 72 can abut against the edge of the electrode frame 8 from the outside of the electrode frame 8, and each limiting member 72 is positioned in the corresponding limiting hole and slot 71 by the corresponding locking member 73, so as to realize multi-point position limiting and / or correction of the electrode frame 8, ensuring the shape and position requirements of the electrode frame 8 during the pressing process, thereby effectively prefabricating the sealing effect between the bonded electrode frame 8 and the diaphragm 9.

[0056] Please refer to the following: Figure 8 and Figure 9 In some embodiments, the locking member 73 includes a rotating head 731 and a threaded rod 732 connected to the rotating head 731. The bearing member 1 has threaded holes at positions corresponding to the limiting slots 71 for threaded connection of the threaded rod 732. Each threaded hole is located within the corresponding limiting slot 71. The limiting member 72 has an elongated countersunk hole. The threaded rod 732 passes through the countersunk hole on the limiting member 72 and connects to the threaded hole. By rotating the rotating head 731, the threaded rod 732 is driven to be threaded into the threaded hole, thereby positioning the limiting member 72 within the limiting slot 71 by the rotating head 731.
