Abstract
In a coating apparatus 100 provided by the present invention an electrode material paste 12 is coated onto an elongated collector 10, to form thereby a coating film 14 of predetermined width in the longitudinal direction of the collector. The coating apparatus 100 includes: a discharge nozzle 20 that discharges the paste 12 onto the collector 10, Which is an object to be coated; a transport pipe 30 that transports the paste 12 up to the discharge nozzle 20; a viscosity measurement unit 40 that measures the viscosity of the paste 12 that is transported within the transport pipe 30; and a gap control unit 50 that modifies a size H of the clearance between the discharge nozzle 20 and the collector 10 on the basis of the viscosity measured by the viscosity measurement unit 40.
Claims12
A coating apparatus for coating an electrode material paste onto an elongated collector and thereby forming a coating film of predetermined width in a longitudinal direction of the collector,
- the coating apparatus comprising:
- a discharge nozzle that discharges said paste onto said collector, which is an object to be coated;
- a transport pipe that is connected to said discharge nozzle and transports said paste up to said discharge nozzle;
- a viscosity measurement unit that is provided halfway said transport pipe and measures the viscosity of said paste that is transported within the transport pipe;
- and
- a gap control unit that is electrically connected to said viscosity measurement unit and modifies a size of a clearance between said discharge nozzle and said collector on the basis of the viscosity measured by the viscosity measurement unit.
A coating method for coating an electrode material paste onto an elongated collector and thereby forming a coating film of predetermined width in a longitudinal direction of the collector,
- the method comprising:
- arranging a viscometer halfway a transport pipe, through which said paste is transported to a discharge nozzle;
- and modifying a size of a clearance between said discharge nozzle and said collector on the basis of the viscosity of said paste measured by the viscometer, in order to adjust the width of said coating film that is coated onto said collector.
