[0002] Battery manufacturers generally use automated production lines to achieve mass production of fuel cells. Automated production lines can automatically perform operations such as stacking, transfer, pressing and offline in sequence. For new models (such as megawatt-level) fuel cells, small-scale trial production is required in the research and development stage in order to discover as many problems as possible and optimize them accordingly, so as to ensure that the products in the mass production stage have high quality and stability. However, most automated production lines have poor versatility, so targeted changes need to be made on the basis of existing automated production lines to meet the trial production needs of new models of fuel cells. Moreover, every time a new model of fuel cell is optimized during the trial production process, the automated production line used for trial production needs to be adjusted accordingly. This will lead to higher trial production costs in the research and development stage. Summary of the invention

[0038] See also Figure 1 and Figure 2 In one embodiment of the present invention, a fuel cell processing device 10 includes a conveying mechanism 100, a stacking fixture 200, a single stack pressing mechanism 300, a flipping mechanism 400, a whole stack pressing mechanism 500 and a hoisting mechanism 600.

[0039] The stacking jig 200 can move between the stacking station and the pressing station driven by the conveying mechanism 100. When the stacking jig 200 moves to the stacking station, the parts can be stacked and assembled into a single stack by manual stacking. For parts with heavier weight, they can be hoisted to the stacking station by the hoisting mechanism 600, and stacking can be completed with the assistance of the hoisting mechanism 600. The hoisting mechanism 600 has strong versatility and can be used to hoist parts of different types and sizes. The manual stacking method is more flexible. During the trial production of new models of fuel cells, if the number, type, stacking order and stacking position of the parts that make up the stack need to be optimized, the operator can flexibly adjust them according to needs.

[0040] After the stacking of the battery stack is completed, the conveying mechanism 100 transfers the stacking jig 200 together with the battery stack to the pressing station, and the single-stack pressing mechanism 300 performs the pressing operation on the battery stack entering the pressing station; after the pressing is completed, the conveying mechanism 100 drives the stacking jig 200 and the battery stack to withdraw from the pressing station, and returns the stacking jig 200 to the stacking station to prepare for the next stacking of the battery stack. Before the next stacking operation of the battery stack is performed, the hoisting mechanism 600 first hoists the battery stack from the stacking jig 200 to the flipping mechanism 400 to empty the stacking jig 200. It should be pointed out that the hoisting mechanism 600 can hoist the compacted battery stack after the stacking jig 200 returns to the stacking station, or it can hoist the battery stack at any position between the stacking station and the pressing station.

[0041] The flipping mechanism 400 can drive the carried battery stack to flip. Specifically, the flipping mechanism 400 can generally drive the battery stack to flip 90 degrees, thereby flipping the battery stack from a vertical state to a horizontal state. As long as the flipping mechanism 400 can carry the battery stack, it can drive the battery stack to flip. It is less restricted by the size and structure of the battery stack and has high versatility. After the battery stack is flipped, the hoisting mechanism 600 can also hoist the battery stack from the flipping mechanism 400 to the whole stack pressing mechanism 500. When the number of battery stacks hoisted to the whole stack pressing mechanism 500 reaches a preset value, such as four, the whole stack pressing mechanism 500 presses multiple battery stacks into a whole stack. Finally, the hoisting mechanism 600 hoists the whole stack out of the whole stack pressing mechanism 500, thereby completing the whole stack unloading.

[0042] It can be seen that with the assistance of the conveying mechanism 100 and the hoisting mechanism 600, the stacking of the battery stack can be completed manually and the battery stack can be pressed, turned over, pressed and unloaded in turn to achieve small-scale trial production. Moreover, due to the high versatility of the conveying mechanism 100, the hoisting mechanism 600, the single stack pressing mechanism 300, the turning mechanism 400 and the whole stack pressing mechanism 500, the fuel cell processing equipment 10 is also more versatile and is less restricted by the size, weight and structure of the battery stack, so it is suitable for trial production of fuel cells of different models. When optimizing the trial-produced fuel cell, it is generally not necessary to modify the various structures in the above-mentioned fuel cell processing equipment 10. Therefore, trial production with the help of the above-mentioned fuel cell processing equipment 10 can significantly shorten the research and development cycle and reduce the trial production cost.

[0043] Please also read Figure 3 In this embodiment, the conveying mechanism 100 includes a conveying base 110, a linear rail 120, a driving assembly 130 and a transfer plate 140. The transfer plate 140 is slidably mounted on the conveying base 110 through the linear rail 120, and the driving assembly 130 can drive the transfer plate 140 to slide along the linear rail 120.

[0044] The stacking jig 200 is carried on the transfer plate 140 and can move along the linear rail 120 with the transfer plate 140, so as to switch between the stacking station and the pressing station. A quick lock structure (not shown) can be provided on the transfer plate 140 to fix the stacking jig 200 to the transfer plate 140, so as to prevent the stacking jig 200 from sliding off the transfer plate 140 during the transfer process. Specifically, the drive assembly 130 generally includes a servo motor and a gear rack. The use of a gear rack in combination with the linear rail 120 for transportation can make the transportation process smooth and free of additional jitter, thereby effectively ensuring the stacking accuracy of the battery stack on the stacking jig 200 during the transportation process.

[0045] In addition, the conveying mechanism 100 is generally also provided with a position sensor (not shown), which may be a photoelectric sensor for real-time detection of the position of the transfer plate 140, thereby facilitating determination of whether the stacking jig 200 has been transferred into place.

[0046] Please also read Figure 4 and Figure 5 The stacking jig 200 includes a jig base plate 210, which has a stacking area for stacking and forming a power supply stack, and each part is stacked on the stacking area to obtain a power supply stack.

[0047] Specifically in this embodiment, the stacking jig 200 further includes a plurality of limit assemblies 220, which are arranged on the surface of the jig bottom plate 210 to form a stacking area. The limit assemblies 220 can abut against the edges of the parts placed in the stacking area, thereby assisting in positioning the parts during the stacking process, thereby ensuring the production quality of the battery stack and maximizing the accuracy of the battery stack production.

[0048] Multiple limit assemblies 220 can be moved closer or farther away from each other, thereby adjusting the size of the stacking area to better meet the trial production requirements of different models of fuel cells. Specifically, each limit assembly 220 includes a limit base 221, a baffle 222 and a pressure plate 223. The limit base 221 can be slidably mounted on the fixture bottom plate 210, and the baffle 222 is fixed to the top surface of the limit base 221 and extends vertically. During the stacking process, the baffles 222 of multiple limit assemblies 220 can assist in positioning the parts. One end of the pressure plate 223 is fixed to the fixture bottom plate 210, and the other end forms a flange that is pressed on the top surface of the limit base 221. Under the pressure of the flange, the stability of the limit base 221 during the positioning process can be improved. Moreover, the flange can also play a guiding role during the sliding of the limit base 221.

[0049] The surface of the limiting base 221 is provided with a waist-shaped hole (not shown), and the limiting base 221 is mounted on the fixture bottom plate 210 by cooperating with a threaded fastener. In this way, the position of the limiting base 221 on the fixture bottom plate 210 can be adjusted, thereby driving the baffle 222 to move to adjust the size of the stacking area.

[0050] In addition, a hard stopper 230 is provided corresponding to each stopper assembly 220. The hard stopper 230 may be a bolt fastened to the fixture bottom plate 210, and may abut against the stopper base 221, thereby limiting the sliding range of the stopper base 221.

[0051] Furthermore, in this embodiment, limiting components 220 are distributed on both sides of the stacking area in the length direction and both sides in the width direction, and at least the limiting components 220 on the adjacent two sides are removable, and after the limiting components 220 are removed, a discharge area for temporarily storing power supply stack parts can be formed on the fixture bottom plate 210.

[0052] In actual use, it is only necessary to set the limiting components 220 on the adjacent two sides of the stacking area to achieve the limiting. Therefore, the remaining limiting components 220 can be removed to leave a discharge area. Lightweight parts, such as single batteries, can be pre-stacked in the discharge area for temporary storage, so that they can be quickly accessed during the stacking process, which helps to improve the stacking efficiency. When the stacking is completed and the battery stack needs to be transferred to the compacting station for compacting operation, the previously disassembled limiting component 220 can be installed. In this way, multiple limiting components 220 will surround the battery stack and better confine the battery stack in the stacking jig 200, thereby preventing the battery stack from moving during the transfer and compacting process, and ensuring the stacking accuracy after the battery stack is compacted.

[0053] For example, the number of the limiting components 220 shown in the figure is 6, 2 limiting components 220 are respectively set on both sides of the length direction of the stacking area, and 1 limiting component 220 is respectively set on both sides of the width direction. When stacking the battery stack, the 2 limiting components 220 on one side of the length direction and the 1 limiting component 220 on one side of the width direction can be removed first, and only the other two sides, a total of 3 limiting components 220, are retained to position the parts during the stacking process.

[0054] Please also read Figure 6 In this embodiment, the single-stack pressing mechanism 300 includes a pressing base 310, a lower pressing head 320, an upper pressing head 330 and a lower pressing assembly 340. The lower pressing head 320 is installed on the pressing base 310. The lower pressing head 320 can carry the stacking fixture 200 entering the pressing station. The upper pressing head 330 and the lower pressing head 320 are arranged opposite to each other along the pressing direction. The lower pressing assembly 340 can drive the upper pressing head 330 to move along the pressing direction.

[0055] The press-fit base 310 plays a supporting role and is generally a metal-formed frame structure. The press-down assembly 340 can provide power for the pressing process. Specifically, the press-down assembly 340 generally includes a servo motor, a servo electric cylinder, a reducer, etc. The above-mentioned pressing direction refers to Figure 6 In the up-down direction shown, the upper pressing head 330 can cooperate with the lower pressing head 320 during the movement in the pressing direction, thereby pressing the battery stack in the stacking jig 200 carried by the lower pressing head 320. Since the stacking jig 200 is supported by the lower pressing head 320, the conveying mechanism 100 can be prevented from being subjected to force during the process of pressing the battery stack, and the force is instead applied to the lower pressing head 320, thereby avoiding damage to the conveying mechanism 100.

[0056] Furthermore, in this embodiment, the press-fitting base 310 includes a plurality of guide rods 311 extending along the pressing direction, and the single-stack press-fitting mechanism 300 also includes a guide seat 350, which is slidably mounted on the guide rod 311 through a guide sleeve 360 ​​sleeved on the guide rod 311, and the upper pressure head 330 is mounted on the guide seat 350.

[0057] The guide sleeve 360 ​​cooperates with the guide rod 311 to guide the guide seat 350. The pressing assembly 340 can drive the guide seat 350 to slide along the guide rod 311, thereby driving the upper pressure head 330 to move along the pressing direction. Moreover, since the guide sleeve 360 ​​cooperates with the guide rod 311 to guide the guide seat 350, the upper pressure head 330 has better stability during movement. Specifically, the top ends of the plurality of guide rods 311 are also provided with an upper mounting plate 312, and the pressing assembly 340 is arranged on the upper mounting plate 312 and is transmission-connected to the guide seat 350.

[0058] Also, please refer again to Figure 1 In this embodiment, the fuel cell processing equipment 10 also includes a lifting mechanism 700, which can drive the stacking jig 200 to rise and fall along the pressing direction to transfer the stacking jig 200 entering the pressing station from the conveying mechanism 100 to the lower pressure head 320, or lift the stacking jig 200 from the lower pressure head 320.

[0059] The lifting mechanism 700 can be arranged below the conveying mechanism 100 or above the conveying mechanism 100. Specifically, in the present embodiment, the lifting mechanism 700 is arranged below the conveying mechanism 100, the conveying mechanism 100 is arranged at the lifting end of the lifting mechanism 700, and the stacking jig 200 is carried on the moving end of the conveying mechanism 100. In other words, the conveying mechanism 100 can be lifted and lowered under the drive of the lifting mechanism 700, thereby driving the stacking jig 200 carried thereon to achieve lifting and lowering.

[0060] Of course, in other embodiments, the lifting mechanism 700 can also be arranged above the conveying mechanism 100. In this case, the stacking jig 200 is carried on the lifting end of the lifting mechanism 700, and the lifting mechanism 700 is installed on the moving end of the conveying mechanism 100. The conveying mechanism 100 can drive the stacking jig 200 and the lifting mechanism 700 to move between the stacking station and the pressing station.

[0061] When the stacking jig 200 is carried on the moving end of the conveying mechanism 100, part of it is suspended, and after entering the pressing station, the suspended part is opposite to the lower pressure head 320. After the stacking of the battery stack is completed at the stacking station, the lifting mechanism 700 first lifts the conveying mechanism 100 and the stacking jig 200 until the bottom surface of the stacking jig 200 is higher than the top surface of the lower pressure head 320; then the conveying mechanism 100 drives the stacking jig 200 to enter the pressing station; then, the lifting mechanism 700 drives the conveying mechanism 100 and the stacking jig 200 to descend until the suspended part of the stacking jig 200 contacts the lower pressure head 320; and as the lifting mechanism 700 continues to descend, the stacking jig 200 can be separated from the conveying mechanism 100, and the lower pressure head 320 can receive the stacking jig 200.

[0062] The lower pressure head 320 is generally provided with an avoidance structure (not shown) to avoid the conveying mechanism 100, thereby ensuring that the conveying mechanism 100 can drive the stacking jig 200 to move above the lower pressure head 320, and allow the movable end of the conveying mechanism 100 to move along the clamping direction at the clamping station. After the clamping operation is completed, the lifting mechanism 700 is lifted again until the stacking jig 200 is lifted from the lower pressure head 320, thereby transferring the stacking jig 200 to the conveying mechanism 100 again. Then, the conveying mechanism 100 can drive the stacking jig 200 and the compacted battery stack out of the compacting station. It can be seen that, driven by the lifting mechanism 700, the stacking jig 200 can be automatically transferred between the lower pressure head 320 and the conveying mechanism 100, and the operation is more convenient.

[0063] Please also read Fig. 9 Specifically, in this embodiment, the lifting mechanism 700 includes a lifting power assembly 710 and a lifting plate 720. The lifting power assembly 710 can be a cylinder, a motor screw pair, etc., and the lifting plate 720 can be lifted and lowered along the pressing direction under the drive of the lifting power assembly 710. The surface of the lifting plate 720 has a large installation area for installing the conveying mechanism 100.

[0064] Please also read Figure 7 and Figure 8 In this embodiment, the flip mechanism 400 includes a flip base 410 and a flip carrier 420, and the flip carrier 420 is rotatably mounted on the flip base 410. The flip carrier 420 is used to carry the battery stack and can drive the carried battery stack to flip.

[0065] When the stack is supported, the flip carrier 420 is in contact with at least the bottom and side surfaces of the stack. Specifically, the flip carrier 420 includes a bottom plate 421 and a side plate 422, and is L-shaped as a whole. In the initial state, the bottom plate 421 extends approximately in the horizontal direction, and the side plate 422 extends approximately in the vertical direction (see FIG. 1 ). Figure 7 ). When the battery stack is placed on the flip carrier 420, the bottom plate 421 of the flip carrier 420 contacts the bottom surface of the battery stack, and the side plate 422 contacts the side surface of the battery stack. At this time, the battery stack is in a vertical state, and the bottom plate 421 bears the weight of the battery stack. When the flip carrier 420 is flipped 90 degrees, the bottom plate 421 of the flip carrier 420 extends roughly in the vertical direction, and the side plate 422 extends roughly in the horizontal direction (see Figure 8 ). At this time, the battery stack is switched to a horizontal state, and the weight of the battery stack is borne by the side plate 422.

[0066] The flip mechanism 400 is generally also provided with a power component, such as a motor or a cylinder, for driving the flip carrier 420 to flip. In addition, the flip mechanism 400 itself may not be provided with a power component, and the flip carrier 420 may be driven by an external power component to flip.

[0067] Furthermore, in this embodiment, the flip mechanism 400 further includes a clamping tool 430, which can clamp the battery stack carried on the flip carrier 420 to limit the position of the battery stack. In this way, the battery stack can be effectively prevented from moving during the flipping process, thereby greatly ensuring the safety of the flipping process.

[0068] Please also read Fig.10 In this embodiment, the lifting mechanism 600 includes a lifting frame 610 and a transfer assembly 620. The lifting frame 610 includes a beam 611 and a column 612. The transfer assembly 620 includes a truss 621 and a lifting structure 622. The truss 621 is perpendicular to the beam 611 and is slidably installed on the beam 611 along the extension direction of the beam 611. The lifting structure 622 is slidably installed on the truss 621 along the extension direction of the truss 621.

[0069] The crossbeam 611 and the column 612 are interconnected to form a frame structure, and the conveying mechanism 100, the stacking fixture 200, the single pile pressing mechanism 300, the flipping mechanism 400 and the whole pile pressing mechanism 500 can be arranged in the frame structure. There are two crossbeams 611, and the two ends of the truss 621 can be respectively arranged on the two crossbeams 611 through rollers and other components. The lifting structure 622 is used to lift parts, battery stacks or whole piles, and a hook can be set on it. The hook is detachable, so that the hook can be installed in different positions according to needs to realize the sharing of the hook in different processes. Since the transfer assembly 620 can slide along the crossbeam 611 as a whole, and the lifting structure 622 can slide along the truss 621, the lifting structure 622 can drive the lifted parts, battery stacks or whole piles to move in two directions perpendicular to each other, and the moving range is large, which is convenient for the smooth transfer of parts, battery stacks or whole piles.

[0070] Furthermore, in this embodiment, the conveying mechanism 100, the stacking fixture 200, the single stack pressing mechanism 300, and the flipping mechanism 400 are all located on the same side of the width direction of the truss 621, the whole stack pressing mechanism 500 is located on the other side of the width direction of the truss 621, and the single stack pressing mechanism 300 and the flipping mechanism 400 are arranged at intervals along the extension direction of the truss 621. Such an arrangement can make the layout of the above-mentioned fuel cell processing equipment 10 more reasonable, and the travel and span of the hoisting mechanism 600 when performing the transfer of parts, fuel cell stacks or whole stacks are small, which is convenient for multiple processes to share the hoisting mechanism 600.

[0071] In the above-mentioned fuel cell processing equipment 10, heavy parts can be hoisted to the stacking station by the hoisting mechanism 600, and the stack can be stacked on the stacking fixture 200 manually; after the stack is pressed and turned over in turn, it can be transferred to the whole stack pressing mechanism 500 by the hoisting mechanism 600; the whole stack finally pressed is hoisted out from the whole stack pressing mechanism 500 by the hoisting mechanism 600. With the assistance of the conveying mechanism 100 and the hoisting mechanism 600, the manually stacked stack can be pressed, turned over, pressed and unloaded in turn. Due to the high versatility of the conveying mechanism 100, the hoisting mechanism 600, the single stack pressing mechanism 300, the turning mechanism 400 and the whole stack pressing mechanism 500, the versatility of the above-mentioned fuel cell processing equipment 10 can be improved. When optimizing the trial-produced fuel cell, generally no changes are required. Therefore, the above-mentioned fuel cell processing equipment 10 can significantly reduce the trial production cost.

[0072] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0073] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
