[0044] The battery cell tray 100 comprises a tray base 3, a first positioning member 1 and a second positioning member 2, both of which are fixed to the tray base 3. The second positioning member 2 is oppositely arranged with the first positioning member 1 along a first direction to form a fixing area 10, and the battery cell 400 can be located in the fixing area 10 and clamped between the first positioning member 1 and the second positioning member 2.

[0045] In the embodiment, the first direction is the ab direction in the figure, and the second direction is the cd direction in the figure. Figure 1 Figure 1 When the battery cell tray 100 moves along the positive direction of the first direction to transport the battery cell 400, the battery cell tray 100 is arranged on the first slide rail 2001 and the second positioning member 2 is located at the front side of the first positioning member 1 along the moving direction. The battery cell 400 has two opposite side surfaces along the first direction and two opposite end surfaces along the second direction, so when the battery cell 400 is placed in the fixing area 10, the first positioning member 1 abuts against at least one side surface of the battery cell 400, and the second positioning member 2 abuts against the other side surface of the battery cell 400, so as to realize the positioning of the battery cell 400 from the first direction. In addition, the second positioning member 2 comprises an abutting portion 21 extending along the second direction, and the projection of the abutting portion 21 on the first direction completely covers the battery cell 400. When the battery cell tray 100 moves along the positive direction of the first direction to transport the battery cell 400, the battery cell 400 is pressed against the abutting portion 21 of the second positioning member 2 by inertia, and the area of the abutting portion 21 completely covers the battery cell 400, so that the positioning of the battery cell 400 by the abutting portion 21 can be realized, and the indentation on the battery cell 400 caused by the pressing of the edge of the abutting portion 21 can be avoided when the battery cell 400 is pressed against the abutting portion 21 by inertia, so as to ensure the product quality of the battery cell 400.

[0046] In the embodiment, the battery cell tray 100 can move back and forth along the first direction, and when the battery cell tray 100 moves along the positive direction of the first direction, the battery cell tray 100 drives the battery cell 400 to move from the initial position to the preset position, and when the battery cell tray 100 moves along the reverse direction of the first direction, the battery cell tray 100 will return to the initial position.

[0047] ​In this embodiment, to enable the tray base 3 to move on the first slide rail 2001, a slider and slide rail structure can be adopted. The first slide rail 2001 includes two tracks arranged opposite each other along a second direction. Sliders are fixedly connected to the sides of the tray base 3 arranged opposite each other along the second direction. The sliders are adapted to the first slide rail 2001 and can slide along the first slide rail 2001 to drive the sides of the tray base 3 and thus drive the cell tray 100 to slide along the first direction. In specific implementations, the automatic movement of the cell tray 100 on the first slide rail 2001 can be achieved by various structures, or the tray base 3 can be manually moved to move the cell tray 100 on the first slide rail 2001, which will not be elaborated here.

[0048] Optionally, the cell tray 100 also includes a drive controller 4, which is signal-connected to the sensing component 300. A drive component is provided on the slider, and the drive controller 4 is electrically connected to the slider drive component to control the operation or stop of the slider drive component, so as to change the position of the slider on the first slide rail 2001, so that the cell tray 100 can move back and forth in the first direction to realize the transmission of the cell 400 and the reset of the cell tray 100 after the transmission of the cell 400.

[0049] In this embodiment, the second positioning member 2 further includes two mounting portions 22, which are disposed opposite to each other at both ends of the abutment portion 21 in the second direction. The second positioning member 2 has a C-shaped structure, which can increase the fixing area 10 between the second positioning member 2 and the tray base 3, ensure the fixing strength between the second positioning member 2 and the tray base 3, and prevent the second positioning member 2 from loosening and shifting due to long-term compression of the battery cell 400.

[0050] The battery cell 400 includes a battery cell body 4001 and two tabs 4002, which are disposed opposite to each other at both ends of the battery cell body 4001 in the second direction. In this embodiment, to avoid positional interference between the second positioning member 2 of the C-shaped structure and the tabs 4002 of the battery cell 400, the dimension of the abutment portion 21 in the second direction can be further extended so that the entire battery cell 400 is located inside the C-shaped structure, which also provides a certain degree of protection for the battery cell 400, i.e., L0≥L1+2L2.

[0051] Optionally, the tray base 3 is provided with multiple sets of mounting holes 31, and the first positioning member 1 and the second positioning member 2 can be fixed to the tray base 3 in an adjustable position through any set of mounting holes 31. In specific implementation, a set of fasteners can be used to pass through a set of mounting holes 31 and be fixed to the first positioning member 1 and / or the second positioning member 2, thereby fixing the first positioning member 1 and / or the second positioning member 2 to the tray base 3. Providing multiple sets of mounting holes 31 makes it convenient to select different sets of mounting holes 31 to fix the first positioning member 1 and / or the second positioning member 2 to the tray base 3 according to different sizes of battery cells 400. In addition, in order to ensure the fixing strength of the first positioning member 1 and / or the second positioning member 2 to the tray base 3, a set of mounting holes 31 includes at least two mounting holes 31. The fastener is connected to one side of the first positioning member 1 or the second positioning member 2 through one mounting hole 31, and the fastener is connected to the other side of the first positioning member 1 or the second positioning member 2 through the other mounting hole 31.

[0052] In specific implementation, multiple mounting holes 31 are provided on the tray base 3. These mounting holes 31 are divided into mounting holes 31 for the first positioning member 1 and / or the second positioning member 2 according to their different positions. The mounting holes 31 for the first positioning member 1 and / or the second positioning member 2 have the same structure. In addition, the position of at least one of the first positioning member 1 and the second positioning member 2 can be adjusted as needed.

[0053] Optionally, the first positioning element 1 and the second positioning element 2 are each provided with N sets, and N fixed areas 10 can be formed on the tray base 3, where N≥1.

[0054] Optionally, the first positioning member 1 has an L-shaped structure, and each set of first positioning members 1 has two members arranged opposite to each other along the second direction. When the battery cell 400 is placed in the fixed area 10, the two first positioning members 1 abut against one side and two end faces of the battery cell 400, while the second positioning member 2 abuts against the other side of the battery cell 400, thereby achieving positioning of the battery cell 400 from the first direction and the second direction.

[0055] In specific implementation, 2N first positioning elements 1 are provided, and N second positioning elements 2 are provided. One second positioning element 2 and two first positioning elements 1 enclose a fixed area 10. N fixed areas 10 can be formed on the tray base 3, where N ≥ 1. The number of fixed areas 10 depends on production needs. In this embodiment, as... Figure 1 As shown, there are four first positioning elements 1 and two second positioning elements 2. Two fixed areas 10 are formed on the tray base 3. Each fixed area 10 can accommodate one battery cell 400, and the size of each fixed area 10 can be adjusted as needed.

[0056] like Figure 2 and Figure 3As shown, this embodiment also provides a battery cell transfer device, including a first slide rail 2001 and the aforementioned battery cell tray 100, wherein the battery cell tray 100 is movably disposed on the first slide rail 2001. When the battery cell tray 100 moves forward along a first direction to transfer the battery cell 400, the battery cell 400 is pressed against the abutment portion 21 of the second positioning member 2 by inertia. At this time, the area of ​​the abutment portion 21 completely covers the battery cell 400. Therefore, the positioning of the battery cell 400 by the abutment portion 21 can be achieved, and the indentation on the battery cell 400 due to the pressure between the battery cell 400 and the edge of the abutment portion 21 when the battery cell 400 is pressed by inertia can be avoided, thus ensuring the product quality of the battery cell 400.

[0057] Optionally, the cell transfer device further includes a sensing component 300 and a drive controller 4. The sensing component 300 is used to detect whether the tray base 3 has moved to a predetermined position, and the drive controller 4 is used to drive and control the movement of the tray base 3. The sensing component 300 is signal-connected to the drive controller 4. That is, when the sensing component 300 detects that the tray base 3 has moved to the predetermined position, it transmits a position signal to the drive controller 4, thereby causing the drive controller 4 to stop driving the tray base 3 to move in the first direction, so that the tray base 3 can stop moving.

[0058] In this embodiment, the sensing component 300 can be a photoelectric sensor. The receiver of the photoelectric sensor is disposed on the tray base 3. The photoelectric sensor determines whether the tray base 3 is in a preset position based on whether the emitted light signal is received by the receiver. When the tray base 3 is in the preset position, the light signal will shine on the receiver. The receiver converts the light signal into an electrical signal and can send it to the drive controller 4.

[0059] Optionally, the cell transfer device further includes a support frame 500, which includes an upper support frame 5001 and a lower support frame 5002. The upper support frame 5001 and the lower support frame 5002 are connected at a distance in the vertical direction, and a first slide rail 2001 is sandwiched between the upper support frame 5001 and the lower support frame 5002. The vertical distance between the upper support frame 5001 and the lower support frame 5002 forms a space for limiting the tray base 3, which can ensure that the tray base 3 can only move along the first direction on the same plane, and will not jump in the vertical direction, thereby ensuring the stability of the transfer of the cell tray 100 to the cell 400.

[0060] In this embodiment, the support frame 500 also includes a support leg 5003, and a lower support frame 5002 is disposed on the support leg 5003 so that the tray base 3 located on the lower support frame 5002 can be at a preset height to meet the production line requirements.

[0061] Optionally, the cell transmission device further includes a second slide rail 2002. Both the first slide rail 2001 and the second slide rail 2002 are mounted on the support frame 500. The first slide rail 2001 and the second slide rail 2002 form the slide rail assembly 200 of this embodiment. The first slide rail 2001 is located above the second slide rail 2002. The tray base 3 is movably mounted on the first slide rail 2001, and the drive controller 4 is movably mounted on the second slide rail 2002. The drive controller 4 can move along the second slide rail 2002 following the movement of the tray base 3, thereby shortening the connection line between the drive controller 4 and the tray base 3. Furthermore, the separate mounting of the drive controller 4 and the tray base 3 facilitates separate maintenance of both components.

[0062] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above embodiments. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
