Background
The bipolar plate is used as a main component in the fuel cell, and the usage and the variety of the bipolar plate are increasing along with the gradual popularization of hydrogen energy power. In a hydrogen energy power system, the electric power of a fuel cell is obtained by the chemical reaction of hydrogen and oxygen, and the hydrogen serving as the fuel is colorless, tasteless, flammable and explosive micromolecule gas and is easy to leak, so that each bipolar plate is required to have good air tightness. At present, the sealing of the bipolar plate is mainly completed by the attachment of the polar plate and the sealing strip, and the polar plate is bonded with the sealing adhesive tape by glue.
Because the structure of the glue coating line of the bipolar plate is complex, the glue amount is required to be uniform and the width is only less than 1mm, the manual operation cannot be completed, the current main method depends on glue coating equipment, and the existing equipment is generally operated by manual feeding, positioning, pressing and blanking. Because the feeding and discharging are convenient, a larger gap is reserved for positioning the polar plate, so that the deviation of the gluing position is caused, and the reject ratio is higher; in addition, because the operation of each step is operated manually, the production efficiency is low, and because the gluing speed of the gluing manipulator is high during gluing, the feeding and discharging area of the equipment operation and the track range of the manipulator are overlapped, so that the potential safety hazard that the manipulator hits a person easily occurs if the operation is wrong.
