[0036] According to one aspect of the utility model, see Figures 1 to 3 The utility model provides a clamping device 100, including a frame 1, a fixture 2, a lifting assembly 3 and a clamping assembly 4; a placement position 21 is formed on the fixture 2, the placement position 21 is used to place the battery cell, and the fixture 2 is slidably installed on the frame 1; the lifting assembly 3 is slidably installed on the frame 1, the lifting assembly 3 includes a driving component 31 and a lifting plate 32, the output shaft of the driving component 31 is connected to one side of the lifting plate 32, the output shaft of the driving component 31 extends or retracts to drive the lifting plate 32 to abut against the fixture 2; the clamping assembly 4 includes two clamping components 41 arranged at intervals, the fixture 2 is located at the two clamping components 41, each clamping component 41 includes a first clamping subcomponent 411 and a second clamping subcomponent 412, the second clamping subcomponent 412 is slidably installed on the first clamping subcomponent 411, the first clamping subcomponent 411 is installed on the frame 1, and the second clamping subcomponent 412 can be used to abut against the side of the battery cell. Specifically, the jig 2 slides on the frame 1. When the jig 2 slides to the loading position, the output shaft of the driving component 31 will extend, pushing the lifting plate 32 up and abutting against the jig 2, so that the jig 2 can move when the stacked battery cells are placed; then the operator stacks the battery cells on the jig 2, or the manipulator 201 stacks multiple battery cells on the placement position 21 at one time. When multiple battery cells are stacked on the placement position 21, the second clamping sub-components 412 on both sides of the battery cells slide on the corresponding first clamping sub-components 411, and the second clamping sub-components 412 on both sides abut against the two sides of the multiple battery cells respectively. Then the output shaft of the driving component 31 retracts, so that the lifting plate 32 does not abut against the jig 2. At this time, the jig 2 can slide on the frame 1, so that the jig 2 slides to the next station to bundle the battery cells; through such a setting, when the stacked battery cells are transported, the battery cells are clamped, so that the battery cells will not fall, which greatly improves the working efficiency.

[0037] See also Figures 1 to 5 In one embodiment, the lifting assembly 3 further includes a mounting plate 33 and a guide rod 34. The mounting plate 33 is slidably mounted on the frame 1. The mounting plate 33 is formed with a guide hole. The cylinder of the driving component 31 is mounted on the mounting plate 33. One end of the guide rod 34 is connected to the lifting plate 32. The other end of the guide rod 34 is telescopically mounted in the guide hole. Specifically, when the fixture 2 moves to a suitable position, the driving component 31 is started, and the output shaft of the driving component 31 will push the lifting plate 32 to rise and abut against the fixture 2, thus completing the fixation of the fixture 2. In this process, since the lifting plate 32 is connected to the guide rod 34, the guide rod 34 will telescopically move in the guide hole. In this way, when the output shaft of the driving component 31 is extended, the telescopic movement of the guide rod 34 in the guide hole can provide a guiding effect for the extension of the output shaft of the driving component 31, and at the same time can support the lifting plate 32, thereby improving the bearing capacity of the entire lifting assembly 3.

[0038] See also Figures 1 to 5 In one embodiment, the number of guide rods 34 is multiple, the number of guide holes is multiple, the number of multiple guide rods 34 is equal to the number of multiple guide holes, and they are arranged one by one.

Specifically, when the operator stacks the battery cells on the jig 2, or the robot 201 stacks multiple battery cells on the placement position 21 at one time, the rotating motor 412d is started, the output shaft of the rotating motor 412d will rotate, and the driving wheel on the output shaft of the rotating motor 412d will also rotate. The driving wheel on the output shaft of the rotating motor 412d is connected to the driven wheel on the screw 412c through the pulley 412e, which will drive the driven wheel and the screw 412c to rotate. At this time, the nut 412a on the screw 412c will move along the length direction of the screw 412c, and the nut 412a is connected to the sliding plate 412b, so that the sliding plate 412b will also move along the length direction of the screw 412c until the sliding plate 412b abuts against the side of the battery cell, so that both sides of the battery cell will be abutted and pressed, so that the battery cell will not fall off when the jig 2 is transported; in this way, the automation of battery cell pressing can be achieved and the labor intensity of the operator can be reduced.

The driving wheel on the output shaft of the rotating motor 412d is connected to the driven wheel on the screw 412c through the pulley 412e, which will drive the driven wheel and the screw 412c to rotate. At this time, the nut 412a on the screw 412c will rotate along the length direction of the screw 412c. Move, the nut 412a is connected to the sliding plate 412b, so that the sliding plate 412b will also move along the length direction of the screw 412c until the sliding plate 412b abuts against the side of the battery cell, so that both sides of the battery cell will be abutted and pressed, and at the same time the clamping plate 412g will also move to the top of the battery cell, so that the battery cell can be pressed from above; through the above structure, the battery cell can be pressed from above and below the battery cell by the clamping plate 412g and the fixture 2, which can further improve the clamping capacity of the clamping device 100 and further prevent the battery cell from falling during transportation.

[0041] Furthermore, the clamping plate 412g is slidably mounted on the sliding plate 412b, so that the position of the clamping plate 412g can be adjusted according to the size of the battery cell and the clamping state of the top of the battery cell, so that the clamping plate 412g can firmly clamp the top of the battery cell.
