[0003] At present, the production line that can produce multiple modules needs to manually adjust the tray or replace the corresponding tray for compatible production when producing a certain module. However, the above tray processing method for compatible production is not conducive to improving the automation rate and flexibility of the production line, and increases the production cost of the production line. Therefore, how to reduce the frequency of manual adjustment of the tray and improve the automation rate of the tray is particularly important.

[0004] The prior art CN 221273826 U discloses a battery cell transfer flexible tray and a battery cell transfer equipment. The battery cell transfer flexible tray includes a base, a first limiting assembly, and a self-locking mechanism. The first limiting assembly is arranged on the base. The self-locking mechanism is arranged on the base and is disengaged under the action of an external force and is reset when the external force is removed. The self-locking mechanism has a compression assembly, and the self-locking mechanism drives the compression assembly away from the first limiting assembly under the action of an external force. However, the technical structure is complex, and to improve the self-locking effect, the self-locking pressure is set to be heavy. When facing different numbers of battery cells, the pressure of the tray still needs to be manually adjusted or the tray needs to be replaced, which is not suitable for locking and positioning of different numbers and sizes of battery cells.

Embodiment 2

[0071] The embodiment provides a battery cell transportation flexible tray, which comprises a bottom plate 1, a linear guide rail 2, a first pressing support 3, a first limiting support 4, a second pressing support 5, and a second limiting support 6.

[0072] The bottom plate 1 comprises a positioning sink 1.1 suitable for battery cell positioning.

[0073] The linear guide rail 2 comprises a guide rail strip 2.1, a sliding block 2.2, and a guide rail clamp 2.3, and the guide rail clamp 2.3 is used for locking and positioning and pressure preservation after guiding the tray.

[0074] The relative movement of the pressing support and the limiting support fixes the battery cell to be transported, and according to the production line compatible production module demand, the number of battery cells fixed by the tray can be freely adjusted, the locking and positioning of the module are preserved, the frequency of manual adjustment of the tray is reduced, and the automation rate of the tray is improved.

[0075] The bottom plate 1 serves as the base of the flexible tray, and bears each component of the tray and the large battery cell of the module, and each component of the tray is fixedly connected to the bottom plate 1 by bolts.

[0076] The two limiting supports and the two pressing supports cooperate with each other, so as to improve the fixing effect of the battery cell.

[0077] Specifically, the sliding directions of the first pressing support 3 and the second pressing support 5 are perpendicular to each other. The sliding directions of the first pressing support 3 and the second pressing support 5 are perpendicular to each other, which is beneficial to more stable fixing of the battery cell. Figure 2 As shown in the figure, the lateral direction and the end direction of the general battery cell are X direction and Y direction respectively.

Its shape is polygonal and it can assist in positioning single-cell, dual-cell, triple-cell, and "grid" four-cell batteries. The depth of the positioning groove 1.1 is 3-8mm, preferably 5mm. The positioning groove 1.1 assists four supports for positioning large batteries.

[0082] like Figure 12 As shown, the positioning sink 1.1 is preferably convex in shape, with the main body being a large rectangle extending along the X and Y directions of the base plate 1, and a small rectangle connected to the edge. Generally, the side length of the large rectangle is twice the length of the battery cell unit, and the side length of the small rectangle is once the length of the battery cell unit.

[0083] In use, the battery cell is secured to the edge by one side of the positioning groove 1.1 that is perpendicular to the length direction of the limiting bracket and another side that is parallel to the length direction of the limiting bracket, which facilitates the arrangement and shaping, and makes it easier for the limiting bracket and the clamping bracket to clamp it in the future.

[0086] The guide rail clamp 2.3 is a standard product identical to the guide rail 2.1 and the slider 2.2. Like the slider 2.2, the guide rail clamp 2.3 is mounted on the first clamping bracket 3 and the second clamping bracket 5. After the tray is in position, the guide rail clamp 2.3 activates, and its internal wedge plate extends to grip the guide rail 2.1, thus locking and positioning the first clamping bracket 3 and the second clamping bracket 5.

[0087] The first clamping bracket 3 and the second clamping bracket 5 are fixed to the slider 2.2 of the linear guide rail 2 with bolts. The first clamping bracket 3 and the second clamping bracket 5 can slide along the linear guide rail 2 to the corresponding positions.

[0088] The battery cell is clamped between the first pressing support 3 and the first limiting support 4 or between the second pressing support 5 and the second limiting support 6, so as to realize locking, positioning and pressure maintaining of the battery cell.

[0089] Specifically, one straight guide rail 2 includes two guide rail strips 2.1 and two sliders 2.2 connected with the two guide rail strips 2.1 respectively. The two guide rail strips 2.1 and the two sliders 2.2 are combined, which is more stable.
