Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of proton exchange membrane production, in particular to a proton exchange membrane slitting device. BACKGROUND

[0002] The proton exchange membrane is a kind of semi-permeable membrane, usually made of ionomer and designed to conduct protons while acting as an electronic insulator and reactant barrier. The proton exchange membrane is mainly used in proton exchange membrane fuel cells as an electrolyte. When combined into a membrane electrode assembly of a proton exchange membrane fuel cell, it can separate reactants and transport protons while blocking direct electron passage through the membrane. The proton exchange membrane is mainly made of pure polymer film and composite film.

[0003] Due to the different sizes of existing proton exchange membrane fuel cells, the proton exchange membrane needs to be cut to the required size during production. The existing proton exchange membrane cutting equipment needs manual operation during the cutting process. Manual operation has low production efficiency and cannot guarantee that the proton exchange membrane can enter the cutting station flatly. It cannot achieve precise control of the cutting size. Although the existing film cutting equipment can improve production efficiency, it cannot be applied to proton exchange membranes. Because the proton exchange membrane of the proton exchange membrane fuel cell needs to be in contact with the membrane electrode, it is necessary to ensure that the proton exchange membrane removes surface dust and static electricity during production to avoid affecting the quality of subsequent production of proton exchange membrane fuel cells.

It is mainly composed of an inner rotor, an outer rotor, a magnetic coil and magnetic powder. It is combined by an input shaft and an output shaft. The space between the two units is filled with granular magnetic powder. When the magnetic coil is not conducting, the torque will not be transmitted from the driving shaft to the driven shaft. However, if the coil is electromagnetically powered, the magnetic force will attract the magnetic powder to produce hardening phenomenon, and the torque will be transmitted between the successive sliding. The magnetic powder brake is a superior automatic control element with the advantages of fast response speed and simple structure.
