Battery cell tray unlocking mechanism and conveying line thereof

The invention relates to the technical field of power battery module assembly, in particular to a battery cell tray unlocking mechanism which comprises a mounting plate mounted on one side of a conveying line and further comprises a side edge drag hook unit slidably mounted on the mounting plate and used for unlocking the side edge of a battery cell tray. The tail drag hook unit is arranged on the mounting plate and is used for unlocking the tail of the battery cell tray; the cam linkage unit is arranged on the mounting plate and is used for driving the side drag hook unit and the tail drag hook unit to execute an unlocking action; the power unit is mounted in the middle of the mounting plate and used for providing driving force for the cam linkage unit; unlocking of the battery cell tray in two directions can be achieved only through one air cylinder linear execution element, the air cylinder linear execution element only needs to be installed on one side of a conveying line, and space is saved. 本发明涉及动力电池模组装
