Abstract

The invention discloses a fuel cell bipolar plate glue line processing device, which relates to the technical field of fuel cells, and includes a hydraulic device and a fixed casing, a connection cavity is arranged in the fixed casing, a connecting assembly is arranged at the upper end of the fixed casing, and the fixed casing The lower end of the rotary head is equipped with a rotating assembly and a rotating head that is connected to the fixed shell in rotation. The rotating head is connected to the rotating assembly. cavity, the lower part of the rotating head is provided with a glue outlet communicating with the communication chamber, two glue width control assemblies are provided, and the two glue width control assemblies are respectively arranged on both sides of the glue outlet. The invention can coat sealants with different widths, which improves the applicability, and can reduce the width and glue output of the sealant at the turning point of the sealant and the T-shaped intersection point, avoiding the formation of hard spots after the fuel cell is extruded, and improving the The sealing effect between the internal structures of the fuel cell is improved.

Description

technical field [0001] The invention relates to the technical field of fuel cells, in particular to a fuel cell bipolar plate glue line processing device. Background technique [0002] The fuel cell stack is composed of multiple layers, each of which needs to be sealed with glue lines, which are applied along the path in liquid state during production. However, since the sealing of the fuel cell stack needs to form a ring, even the ring sealant needs to be continuously coated to divide the interior into multiple different sealing areas. This leads to many turning points and T-shaped intersections in the sealant coating process, and the sealant at the turning points and T-shaped intersections is more than other positions. This leads to the formation of hard spots after pressure sealing, resulting in uneven thickness of the sealant, affecting the sealing effect of the fuel cell, and further affecting the quality of the fuel cell. Contents of the invention [0003] The obje...
