The second drive shaft 124 is a ball screw. The gear 125 is a cylindrical structure with teeth on the outer wall and a hole at the center. The end of the second driver 123 is inserted into the hole to achieve a fixed connection between the second driver 123 and the gear 125. At this time, the second drive shaft 124 still passes through the lifting frame 21 provided with a bearing, but it plays a certain guiding role and will not brake the lifting frame 21.

The servo motor is connected to a push-pull threaded rod. A pull rod is set through the center of the multiple adjustment blocks 242. The pull rod is connected to the push-pull threaded rod. When the third driver 241 drives the push-pull threaded rod to move, the pull rod is pulled or pushed, so that the adjustment block 242 reciprocates horizontally, that is, the height of the rectangular rod is changed by abutting the fixed needle at different positions of the arc-shaped surface of the adjustment block 242, so as to realize the actual height control of the multiple clamping blocks 244.

At this time, it can be extended and retracted under the drive of two stretching members 32 controlled by a programmable logic controller, and the stretching member 32 is a pulling structure of a long rod and a cylinder, and the two long rods are respectively fixed to the two ends of the rolling shutter protective cover 31. Then, after the soft-pack lithium battery 4 is grabbed, before the supporting seat 11 starts to move and transport, the rolling shutter protective cover 31 of the anti-drop component 3 is opened under the drive of the cylinder, so that the bottom of the entire supporting seat 11 frame is wrapped, so that the soft-pack lithium battery 4 falls in the event of unpredictable factors, but will not fall to other internal structures during transportation to affect production; and when it reaches the specified position, the cylinder is controlled by the programmable logic controller to retract the protective cover to avoid affecting the normal progress of the process.

[0072] Through the above solution, the rolling shutter protective cover 31 is controlled to be unfolded or retracted, so that the fallen soft-pack lithium battery cell 4 can be collected without affecting the remaining internal structures, thereby reducing mechanical failures.

[0073] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
