For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood in specific situations.

The specific structure of the battery cell transfer robot according to the embodiment of the present invention will be described below with reference to FIGS. 1 to 4 .

As shown in FIGS. 1 to 4 , the battery cell transfer robot according to the embodiment of the present invention includes a manipulator body 1, a clamping mechanism 2, a pushing member 3 and a matching member 4, and the clamping mechanism 2 is movably arranged on the manipulator body.

It can be understood that, in the actual use process, the process of placing the laminate 100 back in the cache cabinet 200 by the cell transfer robot in this embodiment is that the clamping mechanism 2 clamps the laminate 100, and the clamping mechanism 2 is placed on the robot arm body. Driven by 1, it moves toward the direction close to the cache cabinet 200; when a part of the shelf 100 is supported by the support structure in the cache cabinet 200, the clamping mechanism 2 releases the shelf 100, and then the robot arm body 1 continues to move to make the pusher 3 abuts against the side wall of the laminate 100; after the pusher 3 abuts against the side wall of the laminate 100, the manipulator body 1 continues to move to drive the pusher 3 to slowly push the laminate 100 into the laminate 100 in the storage cabinet. Therefore, the cell transfer robot of this embodiment can realize the function of placing the laminate 100 in the buffer cabinet 200 .

At the same time, the process of removing the laminate 100 from the cache cabinet 200 by the cell transfer robot in this embodiment is as follows: the manipulator body 1 starts to move and makes the fitting 4 fit with the laminate 100 ; the manipulator body 1 continues to move to make the laminate The board 100 leaves the cache cabinet 200 driven by the fitting 4; when a part of the shelf 100 leaves the buffer cabinet 200, the robot arm body 1 stops moving, the fitting 4 separates from the shelf 100 and the clamping mechanism 2 removes the shelf 100 from the buffer Parts of the cabinet 200 are stably clamped; when the clamping mechanism 2 clamps the shelf 100 , the robotic arm body 1 continues to move so that the shelf 100 leaves the cache cabinet 200 driven by the clamping mechanism 2 . Therefore, the cell transfer robot of this embodiment can realize the function of taking the laminate 100 out of the buffer cabinet 200 .

The cell transfer robot according to the embodiment of the present invention has the clamping mechanism 2 for clamping the laminate 100, the pusher 3 for pushing the laminate 100, and the fitting 4 capable of cooperating with the laminate 100.

It can be understood that, because the second driving member 232 can drive the clamping plate 231 to move so as to increase or decrease the distance between the two clamping plates 231, on the one hand, it ensures that the clamping assembly 23 can stably clamp the laminate 100, thereby avoiding The phenomenon of the layer plate 100 falling occurs. On the other hand, for different batteries, the thickness of the layer plate 100 may vary. The thickness between the two clamping plates 231 can be adjusted so that the clamping assembly 23 of this embodiment is compatible with various thicknesses. The laminate 100, so that the entire cell transfer robot can be compatible with laminates 100 with various thicknesses.

At the same time, in this embodiment, the relative movement modes of the two clamping plates 231 can be various. For example, in some embodiments, the two clamping plates 231 are connected to the same second driving member 232.
