The material and structure of the chain 5 determine its wear resistance and service life. The chain 5 is slidably connected to the inner right side of the protective housing 1, installed on the top right side of the protective housing 1, and connected to the driven gear 7, responsible for the auxiliary rotation of the chain 5 to ensure the smooth operation of the chain 5.

[0034] A limiting block 8 is fixedly connected to the outer top end of the chain 5. The limiting block 8 is fixed to the outer top end of the chain 5, used to limit the movement range of the chain 5, and ensure that the chain 5 operates within the set path.

The conveyor belt component 14 consists of two components and is responsible for actually transporting the fuel cell. A deviation correction component is provided on its right bottom side for the precise alignment of the fuel cell.

[0037] Reference Figure 3 、 Figure 4, on the right side of the bottom end of the conveyor belt component 14, a telescopic component for correcting the deviation of fuel cell transportation is provided. The telescopic component includes a positioning ring 15. The top end of the positioning ring 15 is fixedly connected to the right side of the bottom end of the conveyor belt component 14. A telescopic cylinder 16 is slidably connected to the middle of the positioning ring 15.

The top end of the connecting rod 17 is fixedly connected to a push rod 18. The connecting rod 17 connects the telescopic cylinder 16 and the push rod 18, and transmits the deviation correction force through its movement to ensure the reliability of the deviation correction mechanism.

[0038] Rotating blocks one 19 are rotatably connected to the bottom ends of the left and right sides of the push rod 18. Two support blocks 20 are fixedly connected to the right ends of the front and rear sides of the conveyor belt component 14. Rotating blocks one 19 are rotatably connected to the bottom ends of the left and right sides of the push rod 18. The movement of the push rod 18 is used to push and adjust the position of the deviation correction component. The bottom ends of the left and right sides of the push rod 18 are slidably connected to the top ends of the support blocks 20. A rotating block two 21 is rotatably connected to the middle of the top end of the support block 20. The bottom end of the rotating block one 19, at the end far from the rotating block two 21, is rotatably connected to a rotating block three 22. The end of the rotating block one 19 far from the rotating block three 22 is rotatably connected to the top side of the end of the rotating block two 21 close to the rotating block three 22. The bottom end of the rotating block three 22 is slidably connected to the top end of the support block 20. The rotating block one 19 is connected to the rotating block two 21 and the rotating block three 22, and transmits the torque through rotational movement. The bottom ends of the two rotating blocks three 22 are rotatably connected to a deviation correction plate 23. The bottom end of the deviation correction plate 23 is slidably connected to the top end of the conveyor belt component 14. The deviation correction plate 23 is slidably connected to the top end of the conveyor belt component 14 for precisely correcting the deviation of the transported fuel cell to ensure its correct entry into the transportation production line.

[0039] Working principle: By starting the motor 2 to drive the driving gear 4 to rotate, the driving gear 4 drives the driven gear 7 to rotate through the chain 5. At this time, the limiting block 8 outside the chain 5 slides in the placement plate 10, causing the placement plate 10 to slide reciprocally outside the guide rod 9, thereby catching the fuel cell transported on the bottom conveyor belt component 14 and sending it to the top conveyor belt component 14 for transportation. When the limiting block 8 continuously moves, since there is a protruding block at the top end inside the protective shell 1 that blocks the front side of the placement plate 10, the rear side of the placement plate 10 will be driven upward by the continuously enlarged limiting block 8, causing the placement plate 10 to tilt, enabling the fuel cell on the placement plate 10 to slide to the top conveyor belt component 14, realizing the lifting and cyclic transportation of the fuel cell.

[0040] When the fuel cell moves on the top conveyor belt component 14 or during the movement on the top conveyor belt component 14, the shell activates the positioning ring 15 to convey the fuel cell. When the fuel cell reaches the position of the left edge of the deviation rectifying plate 23, the activated telescopic cylinder 16 starts to expand and contract. After the telescopic cylinder 16 expands and contracts, it pulls the connecting rod 17, enabling the connecting rod 17 to push the rotating block three 22 through the rotation of the rotating block one 19 connected by left and right rotation and cooperating with the rotating block two 21. The rotating block three 22 rotates with the bottom end of the end of the rotating block one 19 close to the deviation rectifying plate 23 as the center to push the deviation rectifying plates 23 on the front and back sides of the top of the main conveyor belt to gather, pushing and aligning the fuel cells transported on the main conveyor belt in the center to achieve deviation rectification of fuel cells of different sizes transported by the conveyor belt component 14, ensuring that each fuel cell correctly enters the transportation production.
