Description

Technical Field

[0001] Embodiments of the present invention relate to a synchronous translation device and its control method, and particularly to a sealed film roll conveying and synchronous translation device and its control method. Background Art

[0002] The core component of a fuel cell, the single cell, is formed by encapsulating a bipolar plate and an MEA together through heating and pressurizing a sealing film. The sealing film adheres to the bipolar plate, and its shape is consistent with the trajectory of the sealing surface of the bipolar plate. The sealing film belongs to a type of sealing film. In its normal state, it is a film roll, and a stable and reliable feeding method is required to cooperate with laser cutting. The sealing film has the characteristic of elastic deformation. The traditional winding and unwinding conveying mode itself will cause the sealing film to have tension and tensile deformation, and the self-weight of the sealing film will also cause the sealing film to sag naturally. The above-mentioned defects in the sealing film conveying will result in unstable, oversized or undersized dimensions of the cut sealing film. Especially, the conveying defects of the cut sealing film are more obvious. Since the size of the sealing film is unstable, it will affect the sealing effect of the bipolar plate, and may lead to quality problems such as air leakage. This will cause the quality of the single cell to be unstable and pose a potential hazard to the quality accidents of the fuel cell stack in the later stage. Summary of the Invention
