The invention provides a high-efficiency solar cell double-glass component processing equipment, which is characterized by comprising: a gluing unit; a feeding unit, wherein the feeding unit is arranged at the lower part of the gluing unit; a glass adding unit, the The glass adding unit is arranged at the discharge end of the feeding unit; the enclosure plate adding unit is arranged below the feeding unit; the gluing unit includes a glue-melting pressing roller, and The positioning mechanism and the leveling mechanism are sequentially arranged on the side of the melt glue pressing roller. The troweling mechanism is driven by the reciprocating rod to move up and away from the surface of the film. When the top of the reciprocating rod with the raised part moves to the top of the turntable, the two sets of troweling mechanisms are under the elastic force of the elastic member on the reciprocating rod. The smoothing mechanism slides outward along the middle of the adhesive film to flatten the adhesive film and eliminate the gap between the adhesive film and the battery pack, thereby preventing the phenomenon of blistering and folds during the pasting process of the adhesive film.

A fluid transmitting device includes a side cover connected to a pump impeller and defining a clutch chamber between the side cover and an outer surface of a turbine runner, and a lock-up clutch which includes a clutch piston connected to the turbine runner. The clutch chamber is divided by the clutch piston into an inner oil chamber and an outer oil chamber. In the fluid transmitting device, a dividing means for dividing the inner oil chamber into a primary inner oil chamber section and a secondary inner oil chamber section is provided between the turbine runner and the clutch piston. When a lock-up control device is operated to urge the clutch piston in a clutch switch-on direction, the pressures in the primary inner oil chamber section and the secondary inner oil chamber section are raised in the named order relative to the outer oil chamber. Thus, the connection responsiveness of the lock-up clutch can be enhanced in a simple structure.
