a second driving assembly 40 for driving the pressing member 31 to move toward the supporting portion 11 to clamp the battery cell; and

The suction assembly includes a suction portion 51 provided at a side of the holder 31 facing the bearing portion 11, and a negative pressure generator communicating with the suction portion 51.

In the embodiment of the present utility model, the first driving assembly 20 is disposed on the base plate 21, and the two first mounting plates 14 are slidably connected to the base plate 21. The second driving assembly 40 is fixedly connected with the base plate 21 through a mounting frame 41, the pressing member 31 is arranged between two mounting rods, and can be in a rod-shaped structure, and the pressing member 31 is driven to move downwards by the second driving assembly 40. Specifically, two second driving assemblies 40 may be disposed on the mounting frame 41, and two pressing members 31 may be disposed between the two mounting rods correspondingly. It is noted that, since the battery cells are in a plate-like structure, the area of the peripheral side is small. The supporting piece 10 is only used for supporting the battery cell, and can not clamp four peripheral sides of the battery cell, so that the battery cell is prevented from being damaged. Therefore, the minimum distance between the opposite side walls of the two connecting parts 12 should be larger than the width of the battery cell, so as to avoid clamping the battery cell. Simultaneously, the two connecting parts 12 and the bearing part 11 form a containing space for containing the battery cell. Two supporting members 10 capable of moving in opposite directions are arranged, so that the battery cells can be limited between the supporting members 10, and larger deflection of the battery cells is avoided.

In the embodiment of the present utility model, the first driving assembly 20 includes a first cylinder with a cylinder body disposed on the base plate 21, and the supporting member 10 is disposed at a moving end of the first cylinder, and the first cylinder drives the supporting member 10 to move along a horizontal direction, so that the supporting member 10 moves from one side of the battery cell to a position below the battery cell to receive the battery cell. The support 10 may be a thin plate so as to be horizontally inserted into the lower surface of the battery cell. The hold-down element 31 is arranged parallel to the support element 10 and above the support element 10. The second driving assembly 40 includes a second cylinder connected to the base plate 21, and a driving direction of the second cylinder is along a vertical direction, where the pressing member 31 is disposed at a moving end of the second cylinder, and drives the pressing member 31 to move toward the supporting member 10 until the pressing member 31 abuts against the battery cell on the supporting member 10. Whereby the holder 10 and the press 31 are clamped on the upper and lower surfaces of the battery cell. It should be noted that the first driving assembly 20 and the second driving assembly 40 are not limited to the air cylinder, and linear driving modules such as electric cylinders can be used.

In the embodiment of the present utility model, the suction assembly includes a negative pressure generator, which may be an air pump, and a suction part 51, which is disposed at a side of the holder 31 facing the support part 11 to suck the battery cell. Specifically, the suction portion 51 may be a suction cup, or may be a suction hole or a suction groove provided in the holder 31. The suction cup, the suction hole or the suction groove is communicated with a negative pressure generator through an air pipe, and the negative pressure generator can be started to establish negative pressure at the suction part 51 so as to suck the objects below.

In the discharging stage, the pressing part 31 and the supporting part 10 are far away from the battery cell, and the sucking part 51 keeps sucking the battery cell so as to overcome the acting force exerted on the battery cell by the supporting part 10 during movement, and the battery cell cannot deviate. The force may be a friction force with the lower surface of the cell when the support 10 is retracted. In addition, the pressing member 31 may be driven away from the supporting member 10 by the second driving member 40, the battery cell moves away from the supporting member 10 along with the pressing member 31, after the supporting member 10 is retracted, the second driving member 40 drives the pressing member 31 and the battery cell to descend and place the battery cell at a set position, and then the negative pressure generator stops working to put down the battery cell, so as to complete the discharging step, and avoid the battery cell from shifting when the supporting member 10 is retracted.

In the embodiment of the present utility model, referring to fig. 3 and 4, the air path 34 is provided inside the pressing member 31, and the suction part 51 includes a suction cup communicating with the air path 34.
