Film coating tension component, film drawing mechanism and film coating equipment

The invention discloses a film coating tension component, a film drawing mechanism and film coating equipment, and relates to the technical field of battery film coating. The film-drawing end part assembly is used for being connected with the end part of the film-drawing rod so as to drive the film-drawing rod to execute a film-drawing action, and the film-drawing end part assembly has a floating stroke which floats up and down on the first base part; the connector driving assembly is provided with a floating connector capable of stretching out and retracting, when the floating connector stretches out, the floating connector presses the film-drawing end assembly to move downwards along the floating stroke, and when the floating connector retracts, the floating connector is separated from the film-drawing end assembly, so that the film-drawing end assembly has a floating space in the floating stroke; and the tension assembly comprises at least one elastic piece so as to apply elastic force to the film-drawing
