Coating extrusion head and coating apparatus

A coating apparatus, comprising:

• a coating extrusion head, the coating extrusion head including:
• an extrusion head body provided with an elongated accommodating cavity internally, the elongated accommodating cavity extending along a longitudinal direction, and the extrusion head body being further provided with a coating slot in communication with the elongated accommodating cavity;
• and
• a plurality of pressure regulating assemblies arranged in the elongated accommodating cavity and arranged linearly along the longitudinal direction, each pressure regulating assembly among the plurality of pressure regulating assemblies comprises an expandable structure and a pressure sensor arranged on a surface of the expandable structure, wherein the expandable structure is configured to expand in a first direction perpendicular to the longitudinal direction of the elongated accommodating cavity and perpendicular to an extrusion direction of the coating slot to locally adjust a volume of a corresponding portion along the longitudinal direction of the elongated accommodating cavity, and
• the pressure sensor is configured to detect a pressure on the surface of the expandable structure.

A coating extrusion head, comprising:

• an extrusion head body provided with an elongated accommodating cavity internally, the elongated accommodating cavity extending along a longitudinal direction, and the extrusion head body being further provided with a coating slot in communication with the elongated accommodating cavity, wherein
• the extrusion head body includes an upper extrusion head and a lower extrusion head,
• the upper extrusion head is snap-fitted with an upper portion of the lower extrusion head, and the upper extrusion head and the lower extrusion head jointly define the accommodating cavity, and
• the extrusion head body further includes a sealing gasket arranged at a contact portion between the upper extrusion head and the lower extrusion head;
• and a plurality of pressure regulating assemblies arranged in the elongated accommodating cavity and arranged linearly along the longitudinal direction, wherein
• each pressure regulating assembly among the plurality of pressure regulating assemblies includes an expandable structure and a pressure sensor arranged on a surface of the expandable structure, the expandable structure is configured to expand in a first direction perpendicular to the longitudinal direction of the elongated accommodating cavity and perpendicular to an extrusion direction of the coating slot to locally adjust a volume of a corresponding portion along the longitudinal direction of the elongated accommodating cavity, and
• the pressure sensor is configured to detect a pressure on the surface of the expandable structure.
