(2) Putting the electrode plate group 35.2 into a box for the second time;

since the secondary box entering of the electrode plate group 35.2 is to press the electrode plate group 35.2 into the box body 35.1 until the electrode plate group 35.2 reaches the bottom of the inner cavity of the box body 35.1, in the process, the box body 35.1 needs to be pressed, otherwise, the box entering action cannot be completed, and therefore, the action of the pressing mechanism 33 is generally earlier than that of the jacking mechanism 20;

the pressing plate 34 is driven by the pressing cylinder 31 to descend until the bottom surface of the box body 35.1 is pressed, the lifting cylinder 20.5 drives the lifting plate 20.4 to slide upwards, so that the ejector pin 20.3 gradually approaches to the electrode plate group 35.2, the ejector pin 20.3 contacts the electrode plate group 35.2 and then exerts an upward thrust on the electrode plate group 35.2, and the electrode plate group 35.2 moves upwards due to the fact that the box body 35.1 is pressed until the electrode plate group is completely contacted with the bottom of the inner cavity of the box body 35.1; the pressing cylinder 31 drives the pressing plate 34 to reset, the jacking cylinder 20.5 drives the lifting plate 20.4 to reset, and the storage battery workpiece 35 is released; at the moment, the front sliding table 7 is reset forwards to wait for grabbing the storage battery workpiece 35 next time;

(3) discharging the storage battery workpiece 35;

after a group of storage battery workpieces 35 are placed into the box for the second time, the lifting motor 9 of the rear lifting assembly is started to drive the screw rod 26 to rotate, the rear lifting frame 16 and the rear hand grip 4 are lifted to a set height under the cooperation of the nut 25 and the guide of the guide rail 18, and the rear hand grip 4 reaches the position right behind the storage battery workpieces 35 on the jacking mechanism 20; it should be noted that if the initial setting position of the rear gripper 4 is right behind the secondary boxed battery workpiece 35, this step may be omitted;

the traveling motor 10 of the rear traveling assembly is started, the gear 36 of the rear traveling assembly is driven to rotate through the synchronous wheel and the synchronous belt 13, and the rear sliding table 8 slides forwards to a set position under the cooperation of the rack 17 and the guide of the guide rail 18, so that the movable finger 46 and the fixed finger 47 of the rear gripper 4 are inserted into a gap between the storage battery workpieces 35;

the grabbing cylinder 48 of the rear hand grip 4 is started to drive the movable finger 46 to approach the fixed finger 47, and in the process, the movable finger 46 clamps the storage battery workpiece 35 towards the fixed finger 47;

since the pressing mechanism 33 is reset at this time, the storage battery workpiece 35 has a rising space, and the rear lifting frame 16 rises together with the rear gripper 4, so that the storage battery workpiece 35 is separated from the jacking mechanism 20;

a walking motor 10 of the rear walking assembly is started reversely to drive the rear sliding table 8 to retreat to a set position; the overturning cylinder 39 acts, the driving rack 41 forces the overturning shaft 37 to rotate 180 degrees through the driven gear 42, the rear hand grip 4 fixed at the front end of the overturning shaft 37 and the storage battery workpiece 35 also rotate 180 degrees, and the storage battery workpiece 35 is changed into a box bottom downward from a bus bar 35.4 downward;

at the moment, the storage battery workpiece 35 is positioned above the discharging conveyor belt 57, the lifting cylinder ejects the storage battery workpiece, the rear lifting frame 16 and the rear gripper 4 descend under the guidance of the guide rail 18, and the storage battery workpiece 35 is placed on the discharging conveyor belt 57;

the movable finger 46 releases the storage battery workpiece 35, and the rear lifting frame 16 and the rear gripper 4 are lifted to a set position (at the moment, the discharge conveyor belt 57 is not blocked by the lifting frame and the rear gripper 4, so that the storage battery workpiece 35 can be sent out); the overturning cylinder 39 drives the overturning shaft 37 to rotate for 180 degrees, the rear gripper 4 resets, and the next discharging of the storage battery workpiece 35 is waited;

and at this moment, one-time discharging action of the discharging manipulator is finished.

It should be noted that, in the present invention, each cylinder, motor, travel switch 21, etc. is controlled by a control module (e.g. PLC module), which is a conventional technology in the industry and will not be described in detail herein.
