Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1 and 2, the transfer device in the embodiment of the present utility model may include a bracket 10 and a plurality of jaws 20 disposed on the bracket 10, the plurality of jaws 20 being located on the same side of the bracket 10. Each clamping jaw 20 comprises a first clamping portion 21 and a second clamping portion 22, and the first side of the first clamping portion 21 is connected with the first side of the second clamping portion 22, so that the clamping jaw 20 is of an L-shaped structure as a whole. The connection part between the first side of the first clamping part 21 and the first side of the second clamping part 22 can be used for being clung to the edge of the battery cell, and at this time, the first clamping part 21 and the second clamping part 22 are respectively opposite to two adjacent side surfaces of the battery cell and are contacted with the side surfaces of the battery cell.

In the present embodiment, the number of the clamping jaws 20 is at least two, or the number of the clamping jaws 20 is three or four. When the number of the clamping jaws 20 is two, the two clamping jaws 20 are respectively clung to two edges of the battery cell on the diagonal line, so that the battery cell is uniformly stressed and can be clamped by the transferring device. When the number of the clamping jaws 20 is four, the four clamping jaws 20 are respectively clung to the four edges of the battery cell, so that the acting force for clamping the battery cell can be improved, and the battery cell is more stable in the transferring process. In this embodiment, four jaws 20 are illustrated.

In this embodiment, a first moving component may be provided, and the first moving component may be used to drive the clamping jaw 20 to move along a first direction, where the first direction is a horizontal direction, and may also be understood as a length direction or a width direction of the battery cell. Specifically, the first moving assembly includes a guide rail 30 and a driving device (not shown), and the guide rail 30 is disposed on the bracket 10 and extends in the first direction. Two moving blocks 40 are further provided on the support 10, and each moving block 40 is movable in the first direction relative to the guide rail 30. Wherein two clamping jaws 20 are connected to one moving block 40 and the other two clamping jaws 20 are connected to the other moving block 40, the driving means being operable to drive the moving block 40 to move in a first direction, thereby driving the clamping jaws 20 to move in the first direction.

When the two moving blocks 40 are moved toward each other, the space between the two sets of jaws 20 becomes short, and when the two moving blocks 40 are moved toward each other, the space between the two sets of jaws 20 becomes long. The transfer device in this embodiment is applicable to different sizes of electrical cores by moving the spacing between the clamping jaws 20.

Referring to fig. 1, 2 or 3, the transfer device further includes a second moving assembly 50 in one-to-one correspondence with the clamping jaws 20, the second moving assembly 50 being operable to drive the clamping jaws 20 to move in a second direction, where the second direction is horizontal and the second direction is perpendicular to the first direction. Specifically, the second moving assembly 50 includes a link 52 and an air cylinder 51, and the link 52 is horizontally disposed with one end connected to the air cylinder 51 and the other end connected to the jaw 20. The air cylinder 51 may drive the link 52 to move in the second direction, thereby driving the jaw 20 to move in the second direction. The spacing between the jaws 20 may be varied as each jaw 20 moves in the second direction.

Taking the first direction as the length direction of the battery cell and the second direction as the width direction of the battery cell as an example, when the two moving blocks 40 move along the first direction, the distance between the two groups of clamping jaws 20 along the first direction can be changed, so that the battery cells with different lengths can be adapted. When each clamping jaw 20 moves along the second direction, the spacing between the clamping jaws 20 along the second direction can be changed, so that the electric cores with different widths can be adapted.

In some embodiments, a control module (not shown) may also be provided, which may be used to control the simultaneous operation of the second motion assemblies 50. That is, the cylinders 51 are simultaneously opened or stopped, and the movement distances of the links 52 are the same so that the movement distances of the jaws 20 are the same. It should be noted that of the two sets of jaws 20 arranged in the second direction, the two sets of jaws 20 move in opposite directions when moving.

In some embodiments, the support 10 is also movable in a third direction, here a vertical direction, and the third direction is perpendicular to the first direction and perpendicular to the second direction, which is also understood as the height direction of the cell. When the transfer device needs to clamp the battery cell, after the movable support 10 approaches to the battery cell, the clamping jaw 20 is used for clamping the battery cell, and then the battery cell is transferred back to the original station. Therefore, operators can be prevented from manually placing the battery cells on the transfer device, and automation of the operation process is further improved.

In addition, a rubber gasket can be arranged on the surface of each clamping jaw 20, and the surface of the battery cell cannot be damaged when the clamping jaw 20 is tightly attached to the edge of the battery cell due to elasticity of the rubber gasket.

According to the transfer device provided by the utility model, through the arrangement of the clamping jaw 20 with the L-shaped structure, the clamping of the battery core can be realized by utilizing the fact that the edge in the middle of the clamping jaw 20 is tightly attached to the edge of the battery core, and when a plurality of clamping jaws 20 are clamped simultaneously. Because the edge texture of the battery cell is harder, the insulating blue film on the surface of the battery cell can be ensured not to scratch while the battery cell is clamped.

It will be apparent to those skilled in the art that various modifications and variations can be made to the embodiments of the present utility model without departing from the spirit and scope of the utility model. Thus, it is intended that the present utility model also include such modifications and alterations insofar as they come within the scope of the appended claims or the equivalents thereof.
