Description

Technical Field

[0001] This utility model relates to the field of fuel cells, and in particular to a compressor with a stack rotation function. Background Technology

[0002] A fuel cell is a device that converts the chemical energy of reactants into electrical energy, characterized by high power generation efficiency, low environmental pollution, high specific energy, and high reliability. A fuel cell stack is composed of core components such as end plates, insulating plates, current collectors, bipolar plates, and membrane electrode assemblies (MEAs) stacked together. The stacking and assembly of the fuel cell stack is typically completed on a stacker machine. During the assembly process, pressure is applied to both ends of the fuel cell to tightly assemble components such as end plates, current collectors, bipolar plates, and MEAs.

[0003] During fuel cell stack pressing, the stack is typically pressed from both the top and bottom sides to tightly assemble components such as the pressure plate, current collector, bipolar plates, and membrane electrode assembly. However, this pressing method is unidirectional and cannot accommodate pressing operations in all directions. After pressing the stack from the top and bottom sides, it is necessary to flip the stack to facilitate pressing other sides. Utility Model Content

[0020] like Figures 1-2 As shown in the figure, an embodiment of the present invention provides a rotary press with a fuel cell stack, comprising: Rack 1; A rotating assembly includes a lifting platform 3, a turntable 7, and a driving mechanism for rotating the turntable 7. The lifting platform 3 is slidably disposed at the lower end of the frame 1 in the vertical direction. The lower end of the frame 1 is provided with a first lifting mechanism 6 for driving the lifting platform 3 to slide in the vertical direction. The turntable 7 is rotatably disposed in the middle of the lifting platform 3. The driving mechanism is disposed on the lower surface of the lifting platform 3. The pressurization assembly includes a movable plate 8, a pressure plate 9, a rotating plate 10, and a second lifting mechanism. The movable plate 8 is slidably disposed on the upper end of the frame 1 in a vertical direction. The second lifting mechanism is disposed on the upper end of the frame 1 and is used to drive the movable plate 8 to slide in a vertical direction. The pressure plate 9 is disposed on the lower surface of the movable plate 8. The rotating plate 10 is rotatably disposed on the lower surface of the pressure plate 9 through a slewing bearing. The pressure plate 9 is disposed directly above the turntable 7. The flipping assembly is used to drive the fuel cell stack to rotate around a horizontal straight line inside the frame 1. The flipping assembly includes two rotating clamping mechanisms, which are respectively disposed on opposite side walls of the frame 1.

[0021] The drive mechanism includes a large gear ring 4, a rotating shaft, a pinion 5, and a reduction motor. The large gear ring 4 is rotatably mounted on the lower surface of the lifting platform 3. The rotating shaft passes through the lifting platform 3, and its two ends are coaxially fixed to the large gear ring 4 and the turntable 7, respectively. The pinion 5 is fixed to the output shaft of the reduction motor and meshes with the large gear ring 4. The reduction motor drives the pinion 5 to rotate, which in turn drives the large gear ring 4 to rotate, while simultaneously reducing speed to prevent the turntable 7 from rotating too fast.

[0022] The frame 1 has a base 2 at its bottom, and the first lifting mechanism 6 is disposed on the upper surface of the base 2. The reduction motor is fixed to the lower surface of the base 2, and the output shaft of the reduction motor passes through the base 2. The first lifting mechanism 6 and the pinion 5 are disposed on the upper surface of the base 2 via the reduction motor.

[0023] The tooth width of the large gear ring 4 is smaller than that of the small gear 5. Since the small gear 5 and the reduction motor are mounted on the base 2, and the base 2 is fixed inside the frame 1, when the lifting platform 3 moves up and down, the position of the small gear 5 remains fixed, while the large gear ring 4 moves vertically up and down with the lifting platform 3. Because the tooth width of the large gear ring 4 is smaller than that of the small gear 5, when the gear ring moves vertically up and down, the teeth of the large gear ring 4 will slide vertically up and down along the tooth grooves of the small gear 5, thus maintaining meshing between the large gear ring 4 and the small gear 5.

[0024] Both of the aforementioned rotary clamping mechanisms include a rotary cylinder, a flange, and a cylindrical cylinder 12. The piston rod of the rotary cylinder is a hollow structure. One end of the flange is located on the piston rod of the rotary cylinder, and the other end of the flange is located on the cylindrical cylinder 12. The piston rod of the cylindrical cylinder 12 passes through the flange. The rotary cylinder drives the flange to rotate 90° or 180°, and the cylindrical cylinder 12 rotates synchronously with the flange. After the first lifting mechanism 6 lifts the fuel cell stack, the piston rod of the cylindrical cylinder 12 extends to clamp the left and right sides of the fuel cell stack. Then, the first lifting mechanism 6 resets, suspending the fuel cell stack. After the fuel cell stack is suspended, the rotary cylinder is activated, driving the cylindrical cylinder 12 and the fuel cell stack to rotate, causing the fuel cell stack to rotate around a horizontal straight line.

[0025] The second lifting mechanism includes a servo motor 14, a right-angle planetary reducer 15, two right-angle reducers 16, two crossbeams 13, and two lead screws 17. The servo motor 14, right-angle planetary reducer 15, and right-angle reducers 16 are all mounted on the upper surface of the frame 1. Both lead screws 17 are rotatably mounted inside the frame 1. The right-angle planetary reducer 15 includes an output shaft and an input shaft, which are connected by a bevel gear pair. The two bevel gears of the bevel gear pair are fixed to the middle of the output shaft and one end of the input shaft, respectively. The servo motor 14 is connected to the input shaft, and both ends of the output shaft are connected to the input ends of the two right-angle reducers 16. The upper ends of the two lead screws 17 are connected to the output ends of the two right-angle reducers 16, respectively. The servo motor 14 drives the two lead screws 17 to rotate synchronously.

[0026] The upper surface of the movable plate 8 is provided with a rotary joint, and a pressure sensor is provided at the end of the rotary joint away from the movable plate 8. When pressing the fuel cell stack, the pressure sensor provides feedback on the pressure on the pressing plate 9, which facilitates control of the pressing operation and avoids over-pressing.

[0027] The first lifting mechanism 6 is a miniature cylinder. The first lifting mechanism 6 provides sufficient power to lift the fuel cell stack and the lifting platform 3.

[0028] The frame 1 includes a base plate, a top plate, two side plates, and two guide columns. The two side plates are symmetrically arranged, with their ends fixed to the base plate and top plate, respectively. Two rotating clamping mechanisms are respectively mounted on the two side plates. The two guide columns are symmetrically arranged between the two side plates, with their ends fixed to the base plate and top plate, respectively. Two crossbeams 13 are detachably mounted on the two guide columns by screws. The movable plate 8 slides with the guide columns. The guide columns guide the movable plate 8 and the crossbeams 13. This ensures that the turntable 7 and the pressure plate 9 remain relatively aligned during the vertical movement of the movable plate 8.

[0029] Both side plates are hollow rectangular frames, with a detachable hollow beam 11 inside each side plate. The hollow beam 11 is detachably attached to the side plate at both ends by screws. The rotary cylinder and flange are both located inside the hollow beam 11. The hollow beam 11 has a first through hole and a second through hole on opposite sides. The cylindrical cylinder 12 passes through the first through hole, and its piston rod passes through the second through hole. The hollow beam 11 supports the rotary clamping mechanism, and its position is adjustable to meet the pressure requirements of fuel cell stacks of various heights.

[0030] In one embodiment, the piston rod of the cylindrical cylinder 12 is provided with a fixing plate, and the plane of the fixing plate is perpendicular to the center line of the piston rod of the cylindrical cylinder 12. The fixing plate is used to pressurize the fuel cell stack on both sides.

[0031] The technical features of the embodiments described above can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these should all be considered to be within the scope of this specification.
