Description
Technical Field
[0001] This utility model belongs to the field of fuel cell production and transfer technology, specifically relating to a fuel cell stack transfer device. Background Technology
[0002] A fuel cell stack is assembled by extrusion of end plates, insulating plates, current collectors, and single cells. The single cell includes a bipolar plate (BP). Specifically, the process of installing a single cell involves installing an insulating plate and a current collector on the lower end plate, and then sequentially stacking a bipolar plate, a membrane electrode assembly (MEA), and another bipolar plate on the insulating plate and current collector.
[0003] Multiple individual cells are neatly stacked to form a fuel cell stack, and finally the top plate is stacked on top and the whole assembly is pressed together. A pressure-holding device is installed while maintaining pressure, and then the pressure is released, completing the assembly of one fuel cell stack. The stacking of each component in the fuel cell assembly requires a very high degree of neatness; otherwise, the fuel cell stack will be at risk of leakage. Therefore, extra care must be taken when transporting the fuel cell assembly during the production process. Also, common fuel cell stacks weigh between 15-60 kg, and must be handled with care during transport.
[0004] In existing technologies, manual transfer is commonly used, which is difficult to operate, inefficient, and makes it difficult to ensure the neatness of the fuel cell stack.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] This embodiment uses a mechanical automatic gripper to hold and place the fuel cell stack 5, making the handling of the fuel cell stack 5 stable and safe, solving the problem of damage to the fuel cell stack 5 during manual operation, thereby improving the stacking neatness of all components of the fuel cell stack; through the control unit 2, the automated handling of the fuel cell stack 5 is realized, improving production efficiency.
[0040] In some embodiments, the transport unit 1 includes a mounting plate, guide wheels 11, a positioning component 13, and a drive component 14; multiple guide wheels 11 are provided; multiple guide wheels 11 are connected to the bottom of the mounting plate; the positioning component 13 and the drive component 14 are respectively connected to the mounting plate; the positioning component 13 and the drive component 14 are respectively electrically connected to the control unit 2 for driving the guide wheels 11 to move; 4-8 guide wheels 11 are provided, and the guide wheels 11 are made of rubber or polyurethane; the positioning component 13 is an electronic module capable of transmitting real-time position.
[0041] In actual use, the transport unit 1, according to a pre-set program, picks up the fuel cell stack 5 through the control unit 2 and then transfers it to various assembly stations to complete the production of the fuel cell stack 5.
[0042] In some embodiments, a limiting block 12 is also included; the limiting block 12 is connected to the mounting plate and is located on the side near the lower gripper unit 3 of the fuel cell stack.
[0043] Furthermore, the limiting block 12 is a rectangular strip structure with multiple protrusions on its outer side; the protrusions on both sides have locking holes 122 at the top and bottom of the center position, and the outer side of each protrusion in the middle has a semi-circular limiting hole 121 along the vertical direction.
[0044] In actual use, when the transport unit 1 picks up the fuel cell stack 5 through the control unit 2 according to the pre-set program, it is transferred to each assembly station. When it arrives at each assembly station, the transport unit 1 is connected to each station through the limit block 12 to limit the movement, thus ensuring the stability of the operation.
[0045] In this embodiment, the diameters of the locking hole 122 and the limiting hole 121 are 20-50mm, which enables them to be conveniently and stably connected to the workstation.

[0053] In actual use, when it is necessary to pick up and put down the fuel cell stack 5, the control unit 2 drives the first electric cylinder 21, thereby driving the horizontal plate 351 to move up and down; when the horizontal plate 351 moves up and down, the first slider 32 slides up and down along the first linear guide rail 23, so that the lower gripper 31 moves up and down to meet the need for clamping and releasing when picking up and putting down the fuel cell stack 5.
[0054] In this embodiment, the first steel strip welding groove 311 is provided to reserve a position for welding the steel strip of the fuel cell stack 5, thus avoiding interference.
[0055] In this embodiment, the mounting slot 353 is provided for mounting the second electric cylinder 33, so that the second electric cylinder 33 is placed inside the lower gripper body 35, which not only saves space, but also avoids mutual interference during operation.

[0060] Furthermore, the upper gripper 41 has 3 to 8 parallel second steel strip welding grooves 411; the inner side of the electric cylinder connecting plate 43 has 2 to 4 second sliders 42 on each side.
[0061] In actual use, when it is necessary to pick up and put down the fuel cell stack 5, the control unit 2 controls the second electric cylinder 33 in the lower gripper unit 3 of the fuel cell stack to drive the upper gripper 41 to slide up and down along the second linear guide rail 34 via the second slider 42, thereby adjusting the upper and lower positions of the upper gripper 41 to ensure that the fuel cell stack 5 is clamped and released with the cooperation of the upper gripper 41 and the lower gripper 31.
