The shell can be a battery shell such as an aluminum shell, which is adapted to the appearance of the battery cell, and the rear end of the battery cell is equipped with a cover plate and the front end has a pole ear. The cover plate positioning mechanism (not shown in the figure) is provided between the shell retaining assembly 400 and the battery cell pushing clamping assembly 800 to cap the rear end of the battery cell after entering the shell.

[0041] refer to Figures 1 to 5 , with the X-axis direction being left and right, the Y-axis direction being front and back, and the Z-axis direction being up and down.

[0042] Embodiment 1:

[0043] like Figures 1 to 5 As shown, in this embodiment, a battery cell shelling device 10 includes: a shell positioning platform 100, a guide platform 200 and a battery cell positioning platform 300 arranged in sequence; a shell retaining component 400 for positioning the shell is arranged on the shell positioning platform 100; the guide platform 200 is connected to a guide gate and an alternating clamping component 500 for guiding the battery cell from the guide gate into the shell; the battery cell positioning platform 300 is connected to a pressing component 700, two supporting components 600 for supporting the battery cell and a battery cell pushing clamping component 800 movably arranged between the two supporting components 600, and the two supporting components 600 A conveying channel 110 is formed therebetween, each supporting assembly 600 includes a plurality of supporting plates 610 and a plurality of elastic telescopic units 620, each supporting plate 610 is connected to an elastic telescopic unit 620, and each elastic telescopic unit 620 is sequentially connected to the battery cell positioning platform 300 along the battery cell conveying direction, the pressing assembly 700 is connected to the battery cell pushing clamping assembly 800, when the battery cell pushing clamping assembly 800 is slidably disposed in the conveying channel 110, the pressing assembly 700 cooperates with the elastic telescopic units 620 on both sides to synchronously press down the supporting plates 610 on both sides corresponding to the battery cell pushing clamping assembly 800.

[0044] Specifically, the shell positioning platform 100, the guide platform 200 and the battery cell positioning platform 300 are arranged adjacent to each other from left to right, and the shell retaining assembly 400 is used to clamp and position the three sides of the shell except the entrance when the shell is placed on the shell positioning platform 100. The guide gate has a guide port that passes through the direction from the battery cell positioning platform 300 to the shell positioning platform 100. When the shell is put into the shell, the shell is positioned to be connected with the guide port, and the battery cell can be directed through the guide port and enter the shell, so as to achieve precise guidance of the battery cell into the shell. The alternating clamping assembly 500 is slidably arranged on the guide platform 200, and the alternating clamping assembly 500 is used to push the battery cell into the shell in the guide port. The two support assemblies 600 are arranged relative to each other front and back, and the support plates 610 on both sides jointly support the battery cell, and the elastic telescopic unit 620 supports the support plate 610. The pushing cell clamping assembly 800 slides on the cell positioning platform 300 along a straight line, and in the initial state, the pushing cell clamping assembly 800 is arranged on the side of the cell positioning platform 300 away from the housing positioning platform 100, and when clamping and pushing the cells on the two supporting assemblies 600, the pushing cell clamping assembly 800 slides into the conveying channel 110. The pressing assembly 700 simultaneously presses down the two elastic telescopic units 620 to drive the front and rear support plates 610 below the pushing cell clamping assembly 800 to press down.

[0045] It is worth mentioning that the battery cells are placed on the support platforms on both sides, and the shell is placed on the shell retaining assembly 400. When the battery cells need to be put into the shell, the battery cell clamping assembly 800 is pushed to clamp the battery cells above the two support assemblies 600 and enter the conveying channel 110. During the conveying process, the pressing assembly 700 connected to the battery cell clamping assembly 800 simultaneously presses down the elastic expansion units 620 on the corresponding sides, so that the corresponding elastic expansion units 620 can drive the corresponding support plates 610 to move downward. After the battery cells are conveyed for a period of time, the alternating clamping assembly 500 alternately clamps the battery cells. At this time, the battery cell clamping assembly 800 pushes and moves synchronously with the alternating clamping assembly 500, and when the battery cell clamping assembly 800 moves close to the cover plate, the corresponding support plates 610 below the battery cell clamping assembly 800 are pressed down, thereby generating an avoidance space to prevent the cover plate from contacting the support plates 610. After that, the alternating clamping assembly 500 guides the battery cells into the shell through the guide gate. In this way, multiple support plates 610 are arranged along the conveying direction of the battery cells, which can not only support the battery cells, but also each support plate 610 is respectively provided with an elastic expansion unit 620. In this way, as the battery cell pushing clamping assembly 800 slides, the battery cell pushing clamping assembly 800 pushes the cover plate of the battery cell and drives the battery cell to move as a whole, and simultaneously presses down the support plate 610 at the corresponding position in advance through the pressing assembly 700 to create an avoidance space to avoid contact between the cover plate and the support plate 610, and the support plates 610 at other positions maintain the support and conveying of the battery cells. In this way, while ensuring the smooth conveying of the battery cells, the scratch problem between the cover plate and the support plate 610 that may occur during the shelling process is effectively avoided, thereby effectively improving the yield rate.

[0054] Specifically, the two cam followers 720 are relatively arranged on the front and rear sides of the vertical plate 710. When the battery cell clamping assembly 800 slides in the conveying channel 110, the two cam followers 720 slide in the corresponding pressing parts 624 on both sides, so as to resist the pressing installation plate 621, thereby driving the support plate 610 to press down and avoid.
