Abstract
A sealant coating nozzle and a sealant coating apparatus are provided. The sealant coating nozzle includes a nozzle cavity, a nozzle opening communicated with the nozzle cavity, telescopic inner films located in the nozzle cavity and driving apparatuses configured to drive the telescopic inner films to deform in the nozzle cavity; a volume of the nozzle cavity is reduced by the telescopic inner films in a first deformation state to extrude sealant in the nozzle cavity via the nozzle opening, and the volume of the nozzle cavity is increased by the telescopic inner films in a second deformation state to suck the sealant at the nozzle opening into the nozzle cavity.
