When the lens split charging frame 4 is wholly full, the lens split charging frame is also exactly lifted to the highest point of the last position of the lens split charging stage by the material rack stepping lifting motor 33 and the material rack stepping lifting screw 34, at the moment, under the control of the PLC control system, the outer clamping arm driving cylinder 50 is started, the piston rod of the outer clamping arm driving cylinder 50 retracts, the two driving blocks 52 are synchronously pulled to be close by the synchronous swing rod mechanism, so that the two outer clamping arms 58 are closed, the material rack side clamping pin 59 is inserted into the upper positioning hole of the lens split charging frame 4, and the lens split charging frame 4 full of materials is handed over to the full charging frame lifting jig 26 from the material rack charging jig 25. After the full-load lens sub-charging rack 4 is lifted to a high position by the full-rack lifting jig 26, the full-rack lifting jig 26 releases the fixation of the lens sub-charging rack 4, meanwhile, the full-rack overturning cylinder 42 moves to enable the overturning connecting rod 41 to drive the full-rack overturning rack 27 to overturn around the top end, the full-load lens sub-charging rack is pushed to rotate around the rack positioning bolt, the lens sub-charging rack is changed into a horizontal state or a nearly horizontal state from a vertical state, then the transfer pushing cylinder 42 is started, the full-load lens sub-charging rack is pushed away from the full-rack overturning rack 27 through the transfer pushing rod 48 and is transferred to the full-rack bracket 45, then, the pushing cylinder 44 is started, and the pushing rod 42 is driven to push the lens sub-charging rack 4 to an output inclined sliding plate to slide down and recover. The water gap material of the lens group blank is taken out from the lens group cutting and packaging device through the discharging gripper 6 and transferred to the lens group blank output end 3 to be recovered along the inclined plane sliding.

Example 2:

the number of the lens fixing strips 39 on the lens dispensing frame 4 is three. The rest is the same as example 1.
