[0061] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, and are not used to limit the scope of the present invention.

[0062] Example

[0063] A specific embodiment of the present invention discloses an end-picking and transporting device for battery cells, such as Figure 1 、 Figure 3 and Figure 8 As shown, it includes an end picking portion 100 and a clamping portion 200; the end picking portion 100 includes a bottom plate 110, a length direction adjustment component 120 connected to the bottom plate 110, a width direction adjustment component 130 and a hanging ear 140; the end picking portion 100 clamps the battery cell without blocking the corners of the battery cell; the length direction adjustment component 120 is used to adjust the clamping length; the width direction adjustment component 130 is used to adjust the clamping width; the clamping portion 200 includes a pneumatic clamping jaw 210 and a mounting connector 220, the pneumatic clamping jaw 210 drives the mounting connector 220 to move in the width direction so that the mounting connector 220 is connected to the hanging ear 140, as shown in FIG. Figure 2 shown.

[0064] In this embodiment, the battery cells are arranged on the upper surface of the end picking portion 100, specifically on the upper surface of the length adjustment component 120, and at the same time, the length adjustment component 120 and the width adjustment component 130 do not block the corners of the battery cells, so that when CT is used to detect the four corners of the square battery cells, the rays in the CT detection process are not blocked by the length adjustment component 120 and can be received by the detector, so that the detection is accurate.

[0065] In this embodiment, the length adjustment component 120 and the width adjustment component 130 are adjusted according to the length and width dimensions of the battery cell 300, so that the battery cell 300 is limited to the upper surface of the length adjustment component 120, so that when the clamping part 200 drives the end picking part 100 to move and complete the placement, the battery cell 300 and the end picking part 100 are always in a relatively static state, thereby making it easier to control the placement position of the corners of the battery cell to be detected, reduce the placement position error, and improve the detection accuracy.

[0066] In this embodiment, the clamping part 200 includes a pneumatic clamp 210 and a mounting connector 220. The pneumatic clamp 210 drives the mounting connector 220 to move in the width direction so that the mounting connector 220 is connected to the hanging ear 140, so that the pneumatic clamp 210, the mounting connector 220, the end picking part 100 and the battery cell 300 are always in a relatively static state. By controlling the spatial position of the pneumatic clamp 210, the movement and placement of the battery cell 300 are completed. In this process, since the battery cell 300 does not need to be moved manually, the battery cell will not be damaged due to manual handling.

[0067] The end-picking and transferring device of this embodiment can automatically complete the movement and placement of battery cells without manual movement and placement, and does not require personnel to go in and out of the inspection room many times, thereby significantly improving the inspection efficiency.

[0068] Furthermore, considering that the lengths of the battery cells 300 are different, in order to enable the end pick-up portion 100 to adapt to battery cells 300 of more length types, the length direction adjustment component 120 includes an adjustment plate 121 and a limiting column 122, such as Figure 6 and Figure 7 As shown; more than two adjustment plates 121 cooperate with each other to move to complete the adjustment of the clamping length, and the limiting column 122 is connected to the adjustment plate 121 for clamping and limiting the battery cell in the length direction.

[0069] The two adjustment plates 121 are connected to the base plate 110 to illustrate the mutual cooperation between the adjustment plates 121. The long axis direction of the two adjustment plates 121 is the same as the length direction. The two adjustment plates 121 are arranged side by side in the width direction and perform linear motion in the length direction. The clamping length is adjusted by adjusting the distance between the outer ends of the two adjustment plates 121. When the distance between the outer ends of the two adjustment plates 121 is the smallest, the outer ends of the two adjustment plates 121 extend out of the base plate 110 to ensure that the base plate 110 does not block the corners of the battery cell 300. When the distance between the outer ends of the two adjustment plates 121 is the largest, the inner ends of the two adjustment plates 121 are connected to the base plate 110 to maintain a fixed connection between the adjustment plates 121 and the base plate 110.

[0070] Furthermore, a first oblong hole 1211 is arranged on the adjustment plate 121, such as Figure 6 As shown, the long axis of the first oblong hole 1211 is parallel to the length direction.

The first screw connection member passes through the first oblong hole 1211 and is fixedly connected to the bottom plate 110 , so as to achieve fixed connection between the adjustment plate 121 and the bottom plate 110 .

[0072] In order to prevent the first screw member from protruding from the upper surface of the adjustment plate 121 and damaging the battery cell 300, the first screw member passes through the first oblong hole 1211 and is screwed to the connection hole 113 on the bottom plate 110. The first screw member does not protrude from the upper surface of the adjustment plate 121 when it is screwed. The first oblong hole 1211 is set as a stepped hole. Figure 6 shown.

[0074] In this embodiment, the provision of the transverse oblong hole 124 not only enables position adjustment of the limiting post 122 in the width direction, but also enables stable positioning of the battery cell 300 in the length direction by connecting multiple limiting posts 122 .

[0075] In this embodiment, while the width of the adjustment plate 121 remains unchanged, the end plates 123 of different widths are replaced to prevent the length adjustment assembly 120 from blocking the corners of the battery cells. When the clamping length of the adjustment plate 121 reaches its maximum, the end plates 123 of different lengths are replaced to increase the clamping length.
