COATING DEVICE WITH SYNCHRONOUS MOVING PUMP UNIT WHICH MOVES SYNCHRONOUSLY WITH SLIT DIE COATING HEAD DURING MOVEMENT OF SLIT DIE COATING HEAD AND MAINTAINS CONSTANT POSITION RELATIVELY TO SLIT DIE COATING HEAD AND PIPELINE

摘要

PURPOSE: A coating device is provided to prevent a generation of air bubble in the connection portion between a pump unit and a pipeline or between the pipeline and a slit die coating head, by minimizing the vibration of the pipeline of the coating liquid supplied from a pump unit. CONSTITUTION: A coating device comprises a slit die coating head(220) for sprouting a coating liquid through a slit; a pipeline(230) having an end connected to the top of the slit die coating head such that the pipeline supplies the coating liquid to the slit die coating head; and a moving pump unit(212) connected to the other end of the pipeline so as to supply the coating liquid to the pipeline. The moving pump moves synchronously with the slit die coating head during movement of the slit die coating head, and maintains a constant position relatively to the slit die coating head and the pipeline.
