Description

Technical Field

[0001] The utility model relates to the technical field of fuel cells, and particularly to a fuel cell stack stacking device and system. Background Technique

[0002] The stack plays a crucial role in the fuel cell system and is known as the "heart" of the fuel cell. The stack is the core component for energy conversion in the fuel cell system, responsible for directly converting chemical energy into electrical energy to drive vehicles or other devices; it is the source of power generation in the fuel cell system; the performance of the stack, including power output, efficiency, start-up speed, and stability, directly determines the overall performance of the fuel cell system; the cost of the stack accounts for a large proportion (42% - 62%) of the total cost of the fuel cell system. Therefore, the large-scale production of the stack is of decisive significance for reducing the overall cost of fuel cells and promoting their commercial application; at present, the assembly method of the stack is mostly manual stacking.

[0045] Please refer toFigures 1-4 , this embodiment provides a fuel cell stack stacking device 100, which includes a workbench 110, a material storage unit 130, a grasping component 150, and a stacking unit 170;

[0046] The material storage unit 130 is connected to the workbench 110, and the material storage unit 130 is used for stacking membrane electrodes and bipolar plates; the grasping component 150 is movably connected to the workbench 110, and the grasping component 150 is used for sequentially grasping the membrane electrodes and bipolar plates; the stacking unit 170 is connected to the workbench 110, and the stacking unit 170 is used for receiving the membrane electrodes and bipolar plates sequentially released by the grasping component 150 and forming a stack.

[0047] Please refer to Figures 1-4 , the working principle of this fuel cell stack stacking device 100 is as follows:

[0048] This fuel cell stack stacking device 100 includes a workbench 110, a material storage unit 130, a grasping component 150, and a stacking unit 170;

[0049] Among them, the material storage unit 130 is connected to the workbench 110, and the material storage unit 130 is used for stacking membrane electrodes and bipolar plates, and the number of membrane electrodes and bipolar plates in the material storage unit 130 can be flexibly adjusted;

[0050] The grasping component 150 is movably connected to the workbench 110, and the grasping component 150 is used for sequentially grasping the membrane electrodes and bipolar plates in the material storage unit 130 and sequentially releasing the grasped membrane electrodes and bipolar plates to the stacking unit 170, so as to form a stack in the stacking unit 170;

[0051] Thus, this fuel cell stack stacking device 100 can store a certain amount of stacking materials, and on this basis, through the setting of the grasping component 150, the membrane electrodes and bipolar plates can be quickly transferred and sequentially released to form a stack; therefore, compared with the manual stacking method in the prior art, it is flexible and convenient to use, and can significantly improve the stacking efficiency; compared with the fully automated production line in the prior art, its structure is simple, the use cost can be effectively controlled and reduced, and its structure is also convenient for later optimization and upgrading.

[0052] Furthermore, please refer to Figures 1-7 , in this embodiment, when configuring the grasping component 150, its function is to sequentially grasp the membrane electrodes and bipolar plates in the material storage unit 130 and sequentially release the grasped membrane electrodes and bipolar plates to the stacking unit 170. Thus, the grasping component 150 includes a suction plate 151 and a driving unit 160. The driving unit 160 is connected to the workbench 110, and the driving unit 160 is in transmission connection with the suction plate 151;

[0053] Among them, the driving unit 160 is used to drive the suction plate 151 to move along a first preset direction to change positions between the area directly above the material storage unit 130 and the area directly above the stacking unit 170; or, it is used to drive the suction plate 151 to move along a second preset direction to approach or move away from the material storage unit 130 and the stacking unit 170.

[0054] It should be noted that the purpose of the driving unit 160 to drive the suction plate 151 to move along the first preset direction to change positions between the area directly above the material storage unit 130 and the area directly above the stacking unit 170 is that when the suction plate 151 sucks or releases the membrane electrode and the bipolar plate, it is necessary to maintain its relative position so that it can move along the direction directly opposite to the membrane electrode and the bipolar plate, so as to improve the accuracy of grasping and releasing the membrane electrode and the bipolar plate, and make the external force received by the membrane electrode and the bipolar plate uniform when adsorbing and releasing the membrane electrode and the bipolar plate, so as to avoid deformation of the membrane electrode and the bipolar plate during the process of grasping or releasing.

[0055] Therefore, through the setting of the driving unit 160, the suction plate 151 can move along the first preset direction to change positions between the area directly above the material storage unit 130 and the area directly above the stacking unit 170, and then, after moving to the area directly above the material storage unit 130 or the area directly above the stacking unit 170, drive the suction plate 151 to move along the second preset direction, so as to accurately adsorb or release the membrane electrode and the bipolar plate.

[0056] In this embodiment, the first preset direction is the Figure 3 X-axis direction marked in Figure 3 and the second preset direction is the

[0057] Z-axis direction marked in

[0058] Based on the above structural settings, please refer to Figures 1-7When configuring the driving unit 160, the driving unit 160 includes a first linear driving module 161 and a second linear driving module 162, the second linear driving module 162 is connected to the first linear driving module 161, and the suction plate 151 is connected to the second linear driving module 162; wherein the first linear driving module 161 is used to drive the second linear driving module 162 and the suction plate 151 to move along the first preset direction, and the second linear driving module 162 is used to drive the suction plate 151 to move along the second preset direction. It should be noted that the first linear driving module 161 and the second linear driving module 162 can be linear modules in the prior art, so they will not be described in detail here.

[0059] For further information, please refer to Figures 1-12 In this embodiment, when configuring the stacking unit 170, its function is to receive the membrane electrode and the bipolar plate released in sequence by the grabbing assembly 150 and form a battery stack. Based on this, the stacking unit 170 includes a stacking platform 171, a first lifting assembly 172 and at least one movable positioning rod 173;

[0060] The stacking platform 171 is connected to the workbench 110, and the stacking platform 171 is used to stack membrane electrodes and bipolar plates; the movable positioning rod 173 is movably connected to the stacking platform 171 and the workbench 110 along the second preset direction, and the stacking platform 171 is provided with a through hole for the movable positioning rod 173 to pass through, and the membrane electrode and the bipolar plate are both provided with positioning holes that cooperate with the movable positioning rod 173;

[0061] The first lifting assembly 172 is connected to the side of the workbench 110 away from the stacking platform 171 and is transmission-connected to the movable positioning rod 173. The first lifting assembly 172 is used to drive the movable positioning rod 173 to move relative to the stacking platform 171 so that the end of the movable positioning rod 173 protrudes from the through hole or the positioning hole.

[0062] Therefore, through the above-mentioned structural setting, the movable positioning rod 173 can be pushed to move through the setting of the first lifting component 172, and then when the grabbing component 150 continues to release the membrane electrode and the bipolar plate into the stacking platform 171 in sequence, the movable positioning rod 173 can continue to be above, so that its end can be kept protruding from the positioning hole, that is, a small part of the movable positioning rod 173 can be kept protruding from the positioning hole of the membrane electrode or the bipolar plate, so that the end of the movable positioning rod 173 is slightly higher than the upper plane of the battery stack; and as the materials are continuously stacked, the movable positioning rod 173 continues to rise, so that the highest point of the movable positioning rod 173 is always slightly higher than the upper plane of the battery stack, so that each piece of material is at the top of the movable positioning rod 173 when placed, which can avoid friction between the positioning hole on the material and the movable positioning rod 173.

[0063] It should be noted that as the battery stack is stacked, its height will change, and the release height of the suction plate 151 will be continuously adjusted. Therefore, the coordinates of the released material of the grabbing assembly 150 are positioned by continuously accumulating the thickness of the battery stack on the Z axis from the initial set coordinates. In addition, in order to prevent the movable positioning rod 173 from being unable to extend due to the friction between the movable positioning rod 173 and the battery stack when the movable positioning rod 173 rises, the grabbing assembly 150 can be used to press the battery stack when the positioning rod rises, thereby assisting the movable positioning rod 173 to protrude the positioning hole of the material on the top layer.

[0064] For further information, please refer to Figures 1-12 In this embodiment, the bipolar plate includes a left electrode plate and a right electrode plate. Therefore, when storing materials, it is necessary to meet the storage requirements of the membrane electrode, the left electrode plate and the right electrode plate. Based on this, the storage unit 130 includes three storage modules 131, and the three storage modules 131 are used to store the membrane electrode, the left electrode plate and the right electrode plate respectively;

[0065] Among them, along the first preset direction, the storage module 131 storing the membrane electrode, the stacking unit 170, the storage module 131 storing the left electrode plate, and the storage module 131 storing the right electrode plate are arranged in sequence. Such an arrangement is intended to adapt to the moving direction of the grabbing assembly 150, so that the grabbing assembly 150 can change its position directly above the stacking unit 170 and the three storage modules 131.

[0066] When setting the above-mentioned storage modules 131, since the three storage modules 131 can adopt the same structure, the difference lies in the storage objects and the positions relative to the workbench 110. Therefore, the structure of one of the storage modules 131 is taken as an example for description.

[0067] Specifically, the material storage module 131 includes a material storage platform 132, a second lifting assembly 133 and at least one fixed positioning rod 134;

[0068] The material storage platform 132 is movably connected to the workbench 110 along a second preset direction, and the fixed positioning rod 134 is connected to the workbench 110, and the fixed positioning rod 134 is used to cooperate with the positioning holes of the membrane electrode, the left electrode plate or the right electrode plate stacked on the material storage platform 132;

[0069] The second lifting assembly 133 is connected to the side of the workbench 110 away from the fixed positioning rod 134, and is in transmission connection with the material storage platform 132; the second lifting assembly 133 is used to drive the material storage platform 132 to move relative to the workbench 110, so that the positioning holes of the top membrane electrode, left electrode plate or right electrode plate stacked on the material storage platform 132 cooperate with the end of the fixed positioning rod 134.

[0070] Thus, through the above structural settings, the fixed positioning rod 134 fixedly connected to the workbench 110 can cooperate with the positioning holes of the membrane electrode, the left electrode plate, or the right electrode plate on the material storage platform 132, so as to realize the positioning and stacking of the membrane electrode, the left electrode plate, or the right electrode plate. During this process, since the material storage platform 132 can move relative to the workbench 110 under the action of the second lifting assembly 133, therefore, the second lifting assembly 133 can be used to drive the movement of the material storage platform 132, so that the positioning holes of the top-layer membrane electrode, left electrode plate, or right electrode plate on the material storage platform 132 can cooperate with the end of the fixed positioning rod 134, thus avoiding friction between the positioning hole and the fixed positioning rod 134 when the material is grabbed and preventing jamming.

[0071] Moreover, as the gripping assembly 150 continuously grabs materials, based on the reduction in the number of membrane electrodes, left electrode plates, or right electrode plates on the material storage platform 132, the material storage platform 132 can be lifted under the driving action of the second lifting assembly 133, so that the top-layer membrane electrode, left electrode plate, or right electrode plate thereof is always at a height suitable for the gripping assembly 150 to grab. That is, in this way, it is not necessary for the gripping assembly 150 to adjust the coordinates of its gripping position in the Z-axis direction when grabbing the membrane electrode, left electrode plate, or right electrode plate.

[0072] On this basis, please refer to Figures 1-12 , in order to detect the height of the top-layer membrane electrode, left electrode plate, or right electrode plate on the material storage platform 132, therefore, the material storage unit 130 further includes three high-position sensors 191, and the three high-position sensors 191 are respectively used to detect the height of the top-layer membrane electrode, left electrode plate, or right electrode plate in the material storage module 131. In this way, the height of the top-layer membrane electrode, left electrode plate, or right electrode plate can be detected, and the height data can be fed back to the control system, so as to adjust the height of the top-layer membrane electrode, left electrode plate, or right electrode plate through the second lifting assembly 133.

[0073] In this embodiment, the material storage module 131 further includes two air knife units 192, and the two air knife units 192 are respectively used to obliquely blow air currents towards the material storage module 131 for storing the left electrode plate and the material storage module 131 for storing the right electrode plate.

[0074] Thus, in this embodiment, the problem that bipolar plate materials will stick together when overlapping is solved by the method of obliquely purging with an air knife. Specifically, air knives capable of generating thin air currents are obliquely installed on one side of the material storage module 131 for storing the left electrode plate and the material storage module 131 for storing the right electrode plate. Before the bipolar plates are grabbed, the air knives are controlled to generate high-pressure air currents to obliquely purge the bipolar plates, so as to separate the stuck bipolar plates and prevent the lower bipolar plates from being lifted up or the bipolar plates from not being able to be grabbed when being grabbed.

[0075] In addition, based on the above structure, the fuel cell stack stacking device 100 is further configured with a humidity sensor and a humidifier 193. The purpose is to control the start and stop of the humidifier 193 based on the humidity detection data of the humidity sensor, so as to ensure that the humidity in the working area is always within the set range and prevent the membrane electrode from being damaged due to insufficient humidity.

[0076] It should be noted that, as can be seen from the above content, when positioning the membrane electrode and the bipolar plate, the method adopted is to cooperate with the positioning holes on the membrane electrode and the bipolar plate through the movable positioning rod 173 and the fixed positioning rod 134 to achieve positioning. Such a method can improve the positioning accuracy and effectively avoid the stack failure caused by positioning deviation. Compared with the method of positioning by using the outer frames of the membrane electrode and the bipolar plate in the prior art, the method of this embodiment based on the cooperation of the movable positioning rod 173 and the fixed positioning rod 134 with the positioning holes on the membrane electrode and the bipolar plate can improve the positioning accuracy and avoid misalignment between single cells, thereby avoiding affecting the sealing effect and battery performance.

[0077] It should also be noted that, in this embodiment, based on the above structural settings, a coding and scanning component 194 can be used to cooperate with the stacking to identify, store, analyze and process the numbers of the membrane electrode and the bipolar plate; moreover, since the moving strokes of the first lifting component 172 and the second lifting component 133 are limited, and the lengths of the movable positioning rod 173 and the fixed positioning rod 134 are limited, therefore, the fuel cell stack stacking device 100 can set the stacking groups by itself. For example, it can be determined that 1 bipolar plate and 1 membrane electrode are 1 group. When the stacking group number reaches the set value, the device will stop automatically and give a completion prompt. The numbers of the membrane electrode and the bipolar plate scanned by the system are respectively packaged and generated into 1 two-dimensional code and sent to the label printer 195 for printing.

[0078] Based on the above content, please refer to Figures 1-12 In this embodiment, a fuel cell stack stacking system is provided. The fuel cell stack stacking system includes the above-mentioned fuel cell stack stacking device 100. The fuel cell stack stacking system can stack the bipolar plates and the membrane electrodes into several groups of stack unit modules for packaging and storage. When assembling the stack, directly assemble the required number of unit modules, which is flexible to use, can effectively improve the stack assembly efficiency while ensuring the product quality, and reduce the use cost.

[0079] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
