Description

Technical Field

[0001] The present application relates to the technical field of bipolar plate welding, and in particular to a bipolar plate welding device. Background Art

[0002] At present, most metal bipolar plates of fuel cells use a press plate device to press the cathode plate and the anode plate, and then weld the pressed anode plate and cathode plate to obtain a bipolar plate. In the process of pressing the bipolar plate, the press plate plane and the bipolar plate plane are usually not in good contact due to the lack of parallelism between the press plate plane and the bipolar plate plane, resulting in poor pressing effect of the press plate on the bipolar plate, further resulting in cold welding of the bipolar plate during welding, reducing the welding yield of the bipolar plate. Summary of the invention

[0003] In view of this, the purpose of the present application is to overcome the deficiencies in the prior art and to provide a bipolar plate welding device that can improve the fit between the pressure plate and the bipolar plate.

[0038] Reference Figure 1 as well as Figure 3 As shown, the bipolar plate welding equipment involved in the embodiment of the present application has a first direction, a second direction and a third direction that are perpendicular to each other, and the bipolar plate welding equipment includes: a base 100, a limiting assembly 200, a driving assembly 300 and a pressure plate device 400.

[0039] Specifically, the limiting assembly 200 is connected to the base 100, and the limiting assembly 200 includes two first limiting members 210 spaced apart along the second direction and two second limiting members 220 spaced apart along the first direction, the first limiting member 210 and the second limiting member 220 are spaced apart along the third direction, and the first limiting member 210 has a limiting plane 211 facing the second limiting member 220; the driving assembly 300 is connected to the base 100, and the driving assembly 300 is used to drive the two second limiting members 220 relative to the base 100 moves synchronously along the third direction; the pressure plate device 400 is arranged between the first limit member 210 and the second limit member 220, and the pressure plate device 400 includes a pressure plate assembly 410 and a base plate 420. The pressure plate assembly 410 is arranged close to the first limit member 210, and the base plate 420 is arranged close to the second limit member 220. The pressure plate assembly 410 has a positioning plane 411 facing the first limit member 210; wherein the two limiting planes 211 are located in the same plane, and the positioning plane 411 is arranged parallel to the limiting plane 211.

[0040] It should be noted that the first direction is Figure 1 The direction indicated by x, the second direction is Figure 1 The direction indicated by y, the third direction is Figure 1 The direction indicated by z.

[0041] In the above-mentioned bipolar plate welding equipment, the bottom plate 420 is used for placing the bipolar plate. Since the two second limiting members 220 are arranged at intervals along the first direction, the bottom plate 420 is arranged close to the second limiting member 220, and the driving assembly 300 is used to drive the two second limiting members 220 to move synchronously along the third direction relative to the base 100. Therefore, when the driving assembly 300 drives the two second limiting members 220 to move synchronously along the third direction relative to the base 100, the two second limiting members 220 can respectively contact and abut against the two ends of the bottom plate 420 along the first direction, so that the bottom plate 420 is driven by the two second limiting members 220 to approach or move away from the pressure plate assembly 410 along the third direction. At the same time, the first limiting member 210 can limit the pressure plate assembly 410, so that the bottom plate 420 and the pressure plate assembly 41 0 can be pressed against each other under the common limiting action of the first limiting member 210 and the second limiting member 220, so as to realize the pressing of the bipolar plate. In this process, since the limiting planes 211 of the two first limiting members 210 are located in the same plane, and the positioning plane 411 of the pressing plate assembly 410 is arranged parallel to the limiting plane 211, when the bottom plate 420 moves along the third direction and abuts against the pressing plate assembly 410, it is only necessary to ensure the parallelism between the limiting plane 211 and the bottom plate 420. Then, the fitting degree between the pressing plate assembly 410 and the bottom plate 420 can be adjusted by limiting the positioning plane 411 by the limiting plane 211, so as to improve the fitting degree between the pressing plate and the bipolar plate, thereby improving the pressing effect of the pressing plate device 400 on the bipolar plate, and improving the welding effect of the above-mentioned bipolar plate welding equipment on the bipolar plate.

[0042] Reference Figure 2 As shown, the driving assembly 300 includes two first driving members 310, each of which is connected to the base 100, and each of which is drivingly connected to a second limiting member 220 to drive the two second limiting members 220 to move synchronously along a third direction relative to the base 100.

[0043] Specifically, the two first driving members 310 are arranged at intervals along the first direction.

[0044] More specifically, the first driving member 310 is a cylinder, and two avoidance holes arranged at intervals along the first direction are opened on the bottom plate 420. The cylinder barrel of each cylinder is connected to the side of the base 100 away from the limit assembly 200 along the third direction. The piston rod of each cylinder is passed through an avoidance hole and connected to a second limit member 220. The piston rod moves in the avoidance hole along the third direction to drive the second limit member 220 to move along the third direction.

[0045] In this embodiment, the two second limit members 220 can be driven by two driving members to move synchronously along the third direction relative to the base 100, so that the two limit members push the two ends of the bottom plate 420 along the first direction to move along the third direction at the same time, so as to improve the parallelism of the bottom plate 420 with the pressure plate assembly 410 during the movement, thereby improving the fit between the pressure plate assembly 410 and the bottom plate 420, and improving the fit between the pressure plate and the bipolar plate, so as to improve the pressing effect of the pressure plate device 400 on the bipolar plate, and improve the welding effect of the above-mentioned bipolar plate welding equipment on the bipolar plate.

[0046] Reference Figure 3 As shown, the pressure plate assembly 410 includes a peripheral pressure plate 412 , and both ends of the peripheral pressure plate 412 along the second direction have positioning planes 411 , one of the positioning planes 411 is connected to one of the limiting planes 211 , and the other positioning plane 411 is connected to the other limiting plane 211 .

[0047] In this embodiment, the peripheral pressure plate 412 is used to press the edge of the bipolar plate. Since the peripheral pressure plate 412 has positioning planes 411 at both ends along the second direction, one of the positioning planes 411 is connected to one of the limiting planes 211, and the other positioning plane 411 is connected to the other limiting plane 211. Therefore, the parallelism between the peripheral pressure plate 412 and the first limiting member 210 can be improved by connecting the two positioning planes 411 to the corresponding limiting planes 211 respectively. In this way, it is only necessary to make the first limiting member 210 meet the parallelism with the bottom plate 420 to improve the fit between the bottom plate 420 and the peripheral pressure plate 412, thereby improving the pressing effect of the pressure plate device 400 on the edge of the bipolar plate.

[0048] Reference Figure 1 as well as Figure 4 As shown, the pressure plate assembly 410 also includes an internal pressure plate 413 arranged inside the outer pressure plate 412, and the bipolar plate welding equipment also includes a plurality of clamping assemblies 500, and at least one clamping assembly 500 is arranged at both ends of the internal pressure plate 413 along the second direction, and the clamping assembly 500 has a clamping force that causes the internal pressure plate 413 to move along the third direction toward the second limit member 220.

[0049] Specifically, a plurality of clamping assemblies 500 are provided at both ends of the internal pressure plate 413 along the second direction, and the clamping assemblies 500 located at one end of the internal pressure plate 413 along the second direction are symmetrically arranged with the clamping assemblies 500 located at the other end of the internal pressure plate 413 along the second direction.

[0050] In this embodiment, the internal pressure plate 413 is used to press the inside of the bipolar plate. Since at least one clamping assembly 500 is provided at both ends of the internal pressure plate 413 along the second direction, the clamping assembly 500 has a clamping force that causes the internal pressure plate 413 to move along the third direction toward the second limit member 220. In this way, a clamping force can be applied to the internal pressure plate 413 by multiple clamping assemblies 500 to increase the pressing force between the internal pressure plate 413 and the bottom plate 420, thereby improving the pressing effect on the bipolar plate.

[0051] Reference Figure 4 As shown, the clamping assembly 500 includes a second driving member 510, a connecting rod 520 and a clamping member 530. The second driving member 510 is connected to the first limiting member 210. Both ends of the connecting rod 520 are respectively connected to the second driving member 510 and the clamping member 530, and the clamping member 530 is arranged on one side of the connecting rod 520 along the third direction close to the internal pressure plate 413. The second driving member 510 is used to drive the connecting rod 520 to move along the third direction and drive the connecting rod 520 to rotate around the third direction.

[0052] In this embodiment, the connecting rod 520 can be driven to rotate about a third direction by the second driving member 510, so that the connecting rod 520 drives the clamping member 530 to approach or move away from the internal area of ​​the internal pressure plate 413. At the same time, when the connecting rod 520 drives the clamping member 530 to rotate about the third direction to the internal area of ​​the internal pressure plate 413, the connecting rod 520 can be driven to move along the third direction by the second driving member 510, so that the connecting rod 520 can drive the clamping member 530 to move along the third direction and approach the internal pressure plate 413, so that the clamping member 530 can be against the internal pressure plate 413 and apply a clamping force to the internal pressure plate 413 toward the second limit member 220, so as to increase the pressing force between the internal pressure plate 413 and the bottom plate 420, thereby improving the pressing effect on the bipolar plate.

[0053] Specifically, continue to refer to Figure 4As shown, the clamping assembly 500 also includes a connecting plate 540 fixed to the first stopper 210, and a first connecting hole 541 extending along the first direction is opened on the connecting plate 540. The second driving member 510 is connected to the connecting plate 540 by a fastener (not shown), and the fastener is inserted into the first connecting hole 541. The relative position of the second driving member 510 and the internal pressing plate 413 in the first direction can be adjusted by adjusting the position of the fastener in the first connecting hole 541. The end of the connecting rod 520 away from the second driving member 510 is opened. A second connecting hole 521 extending along its length direction is provided, and the clamping member 530 is connected to the connecting plate 540 by a fastener (not shown), and the fastener is passed through the second connecting hole 521. The relative position of the clamping member 530 and the internal pressure plate 413 in the second direction can be adjusted by adjusting the position of the fastener in the second connecting hole 521. In this way, the relative position relationship between the clamping assembly 500 and the internal pressure plate 413 can be adjusted, so that the clamping assembly 500 can provide a more uniform clamping force for the internal pressure plate 413.

[0054] Reference Figure 1 As shown, the bipolar plate welding device also includes two fixing components 600, which are symmetrically arranged at both ends of the internal pressure plate 413. When the driving component 300 drives the two second limiting members 220 to move along the third direction toward the direction close to the base 100, the two fixing components 600 are fixedly connected to the internal pressure plate 413.

[0055] Specifically, the two fixing assemblies 600 are symmetrically disposed at two ends of the inner pressing plate 413 along the first direction.

[0056] In this embodiment, when the driving assembly 300 drives the two second limiting members 220 to move along the third direction toward the base 100, the bottom plate 420 disengages from the pressure plate assembly 410. At this time, the pressure plate assembly 410 is at risk of falling along the third direction toward the base 100. Since the outer pressure plate 412 is fixedly connected to the first limiting member 210, the first limiting member 210 can be used to prevent the outer pressure plate 412 from falling. Since the two fixing assemblies 600 are fixedly connected to the internal pressure plate 413, the two fixing assemblies 600 can be used to prevent the internal pressure plate 413 from falling, thereby ensuring the structural stability of the pressure plate assembly 410. When the driving assembly 300 drives the two second limiting members 220 to move along the third direction toward away from the base 100, the bottom plate 420 and the pressure plate assembly 410 are pressed against each other. At this time, in order to ensure the pressing force between the bottom plate 420 and the pressure plate assembly 410, it is only necessary to separate the fixing assembly 600 from the internal pressure plate 413 so that the internal pressure plate 413 can be pressed on the bottom plate 420 due to gravity.

[0057] Reference Figure 5As shown, the fixing assembly 600 includes a third driving member 610 and a fixing member 620 drivingly connected to the third driving member 610. The internal pressure plate 413 has a connecting member 414. The third driving member 610 drives the fixing member 620 to move closer to or away from the internal pressure plate 413 so that the fixing member 620 is connected to or disconnected from the connecting member 414.

[0058] In this embodiment, after the welding of the bipolar plate is completed, the two third driving members 610 simultaneously drive the fixing members 620 connected thereto to approach the internal pressure plate 413, so that the fixing members 620 are connected to the connecting members 414 of the internal pressure plate 413, so that the internal pressure plate 413 is fixed by the two fixing members 620. At this time, the two second limiting members 220 can be driven by the driving assembly 300 to move along the third direction toward the direction close to the base 100, so that the bipolar plates that have been welded can enter the next process.

[0059] Specifically, continue to refer to Figure 5 As shown, one end of the fixing member 620 facing the internal pressure plate 413 is provided with a slot 621 with an opening facing the internal pressure plate 413, and the connecting member 414 has a connecting portion 4141 and a limiting portion 4142, and the two ends of the connecting portion 4141 are respectively connected to the limiting portion 4142 and the internal pressure plate 413, and the limiting portion 4142 protrudes from the connecting portion 4141. When the third driving member 610 drives the fixing member 620 to approach the internal pressure plate 413, the connecting portion 4141 can be embedded in the slot. 621, and the limiting portion 4142 abuts against the edge of the slot 621 to achieve a fixed connection between the fixing member 620 and the connecting member 414, so that the fixing members 620 located at both ends of the internal pressure plate 413 can lift the internal pressure plate 413 to achieve fixation of the internal pressure plate 413. When the third driving member 610 drives the fixing member 620 away from the internal pressure plate 413, the connecting member 414 can be disengaged from the slot 621 to achieve the disengagement of the fixing member 620 from the connecting member 414.

[0060] Reference Figure 2 as well as Figure 3 As shown, the limiting assembly 200 also includes two brackets 230 spaced apart along the first direction, and one end of each bracket 230 along the third direction is connected to the base 100. In the first direction, one end of each first limiting member 210 is connected to one end of one of the brackets 230 away from the base 100 along the third direction, and the other end of each first limiting member 210 is connected to one end of the other bracket 230 away from the base 100 along the third direction.

[0061] Specifically, one of the third driving members 610 is connected to one end of one of the brackets 230 along the third direction away from the base 100, and the other third driving member 610 is connected to the other end of the bracket 230 along the third direction away from the base 100, and each third driving member 610 is located between the two first limiting members 210 to fix the third driving member 610.

[0062] In this embodiment, the two first limit members 210 can be fixed by two brackets 230, so that the two first limit members 210 can be spaced apart from the base 100 along the third direction, so that the bottom plate 420 can move along the third direction between the first limit members 210 and the base 100, so that the bipolar plate can be moved away from the base 100 along the third direction to be pushed to the welding station, or away from the base 100 along the third direction to be pushed away from the welding station, so as to improve the cycle efficiency of the bipolar plate welding process.

[0063] Reference Figure 1 as well as Figure 2 As shown, the bipolar plate welding equipment also includes a supporting assembly 700, which includes a supporting member 710. The supporting member 710 is located between the first limiting member 210 and the base 100. The bottom plate 420 is placed on the supporting member 710, and the two ends of the bottom plate 420 along the first direction are suspended.

[0064] In this embodiment, the bottom plate 420 can be placed on the supporting member 710, and the two ends of the bottom plate 420 along the first direction are suspended. In this way, when the second limiting member 220 moves along the third direction toward a direction away from the base 100, the two ends of the bottom plate 420 along the first direction can be respectively abutted against a second limiting member 220, and can move along the third direction with the second limiting member 220 toward a direction away from the base 100, so as to realize the pressing of the bottom plate 420 and the pressure plate assembly 410.

[0065] Reference Figure 2 as well as Figure 6 As shown, the supporting member 710 has a first work station area 711 and a second work station area 712 on one side along the third direction toward the first limiting member 210. The two brackets 230, the first limiting member 210 and the base 100 are arranged to form an avoidance space 800. The supporting assembly 700 also includes a fourth driving member 720 driven and connected to the supporting member 710. The fourth driving member 720 is connected to the base 100 and drives the supporting member 710 to rotate around the third direction so that the first work station area 711 or the second work station area 712 is located in the avoidance space 800.

[0066] Specifically, when the first workstation area 711 is located outside the avoidance space 800 , the second workstation area 712 is located inside the avoidance space 800 ; and when the second workstation area 712 is located outside the avoidance space 800 , the first workstation area 711 is located inside the avoidance space 800 .

[0067] In this embodiment, the first work station area 711 and the second work station area 712 are both used for placing the bottom plate 420. When the first work station area 711 is located outside the avoidance space 800, the bottom plate 420 is placed on the first work station area 711, and the fourth driving member 720 drives the supporting member 710 to rotate around the third direction, so that the first work station area 711 rotates into the avoidance space 800, so that the bottom plate 420 can rotate into the avoidance space 800, and move along the third direction with the second limiting member 220 in the avoidance space 800 to the welding station. At this time, another bottom plate 420 can be placed on the second work station area 712 located outside the avoidance space 800. When the bottom plate 420 in the avoidance space 800 completes welding and returns to the first workstation area 711, the fourth driving member 720 can drive the supporting member 710 to rotate around the third direction, so that the first workstation area 711 rotates into the avoidance space 800, and the second workstation area 712 rotates out of the avoidance space 800, so that the finished product of the first workstation area 711 can enter the next process, and at the same time, the bottom plate 420 on the second workstation area 712 moves along the third direction to the welding station in the avoidance space 800 with the second limiting member 220. In this way, the welding efficiency of the above-mentioned bipolar plate welding equipment can be improved by setting two workstations on the supporting member 710.

[0068] Specifically, each bracket 230 is a U-shaped bracket 230, the openings of the two U-shaped brackets 230 are arranged relatively along the first direction, and the distance between the U-shaped bottom walls of the two U-shaped brackets 230 is greater than the diagonal length of the supporting member 710, so that the supporting member 710 will not interfere with the U-shaped bracket 230 when rotating about the third direction.
