[0071] Embodiment one:

[0072] As Figures 1-7As shown, in the embodiment, a grading cache mechanism, comprising: a bottom plate 1; a first grading rack 2, having a plurality of first grading portions 22 arranged along the horizontal X-axis direction; a second grading rack 3, having a plurality of second grading portions 32 arranged along the horizontal X-axis direction, the second grading portions 32 on the second grading rack 3 being arranged staggered along the horizontal X-axis direction with the first grading portions 22 on the first grading rack 2; a third grading rack 4, having a third grading portion 44 arranged along the horizontal X-axis direction; and a fourth grading rack 5, having a fourth grading portion 53 arranged along the horizontal X-axis direction, the third grading portion 44 and the fourth grading portion 53 being arranged spaced apart along the horizontal Y-axis direction.

[0073] The grading cache mechanism is used to temporarily store the batteries 100 classified according to predetermined performance parameters, for subsequent production and use. The grading cache mechanism generally comprises a plurality of storage units, each of which can accommodate a battery. However, the storage units on the existing grading cache mechanism can only store batteries of the same size, and when the battery is replaced, the grading structure needs to be disassembled and then assembled with a grading structure suitable for the battery, which is not only inefficient but also difficult to install and debug.

[0074] Therefore, the size of the storage area on the grading cache mechanism is adjustable in the embodiment, so that the application range is wider.

[0075] Specifically, the first grading rack 2 or the second grading rack 3 is slidably arranged on the bottom plate 1 along the horizontal X-axis direction, and the third grading rack 4 or the fourth grading rack 5 is slidably arranged on the bottom plate 1 along the horizontal Y-axis direction.

[0076] The grading cache mechanism further comprises an adjusting device for driving the first grading rack 2 or the second grading rack 3 to move, so as to adjust the distance between the adjacent first grading portions 22 and the second grading portions 32, and for driving the first grading rack 2 or the second grading rack 3 to move, so as to adjust the distance between the adjacent third grading portions 44 and the fourth grading portions 53.

[0077] The bottom plate 1 is a plate-shaped structure for supporting the batteries 100, and then by arranging the first grading rack 2, the second grading rack 3, the third grading rack 4 and the fourth grading rack 5, the area above the bottom plate 1 is divided into a plurality of square storage areas. After the battery 100 is placed in the storage area, the relative positions between the first grading rack 2 and the second grading rack 3 and the relative positions between the third grading rack 4 and the fourth grading rack 5 can be adjusted by the adjusting device according to the size of the battery 100, so that the area enclosed by the first grading portions 22, the second grading portions 32, the third grading portions 44 and the fourth grading portions 53 is enlarged or reduced, thereby limiting the battery 100 in the horizontal plane.

[0078] In the embodiment, the first, second, third and fourth sub-racks are movably arranged for facilitating adjustment and improving the adjustment efficiency of the relative positions between the first and second sub-racks 2 and 3 and the relative positions between the third and fourth sub-racks 4 and 5. Specifically, the first and second sub-racks 2 and 3 are slidably arranged on the bottom plate 1 along the horizontal X-axis direction, and the third and fourth sub-racks 4 and 5 are slidably arranged on the bottom plate 1 along the horizontal Y-axis direction; the adjustment device is configured to drive the first and second sub-racks 2 and 3 to move synchronously to adjust the interval between the adjacent first and second sub-racks 22 and 32; and to drive the first and second sub-racks 2 and 3 to move synchronously to adjust the interval between the adjacent third and fourth sub-racks 44 and 53.

[0079] In the embodiment, the first, second, third and fourth sub-racks are movably arranged for facilitating adjustment and improving the adjustment efficiency of the relative positions between the first and second sub-racks 2 and 3 and the relative positions between the third and fourth sub-racks 4 and 5. Specifically, the first and second sub-racks 2 and 3 are slidably arranged on the bottom plate 1 along the horizontal X-axis direction, and the third and fourth sub-racks 4 and 5 are slidably arranged on the bottom plate 1 along the horizontal Y-axis direction; the adjustment device is configured to drive the first and second sub-racks 2 and 3 to move synchronously to adjust the interval between the adjacent first and second sub-racks 22 and 32; and to drive the first and second sub-racks 2 and 3 to move synchronously to adjust the interval between the adjacent third and fourth sub-racks 44 and 53.

[0080] At present, when the battery is placed in the storage area, the four corners and about half of the side surface of the battery are in contact with the sheet metal of the sub-rack mechanism, which causes the bottom and side surface of the blue film of the battery to be easily scratched, and thus the battery needs to be re-teared and returned to work, which wastes a lot of manpower and resources.

[0081] Therefore, the structure of each sub-rack is improved in the embodiment, and specifically, each sub-rack is arranged in a cylindrical roller structure. When the robot gripper places the battery in the storage area, the battery rolls down after being in contact with the roller, so that the battery is stably placed on the bottom plate 1. This design avoids the risk of scratching the blue film of the battery.

[0082] It should be noted that the sub-rack buffer mechanism of the embodiment can also be used for storage of other workpieces and is not limited to the field of batteries.

[0083] Embodiment Two

Specifically, the first sub-rack parts 22 on the first sub-rack 2 and the second sub-rack parts 32 on the second sub-rack 3 are arranged at intervals, then the first sliding rails 23 are arranged on the bottom of the bottom plate 1, and the first sub-rack 2 and / or the second sub-rack 3 are arranged on the first sliding rails 23 in a sliding manner, so that by moving the first sub-rack and / or the second sub-rack 3, the distance between the adjacent first sub-rack parts 22 and the second sub-rack parts 32 can be changed.

[0088] It should be noted that, in order to avoid interference between the first sub-rack 2 and the second sub-rack 3, the first sub-rack parts 22 and the second sub-rack parts 32 can be arranged staggeredly, or the first sub-rack parts 22 and the second sub-rack parts 32 can be arranged horizontally, but the first sub-rack parts 22 need to pass through the second side plates 31 and be able to move horizontally on the second side plates 31, or the second sub-rack parts 32 need to pass through the first side plates 21 and be able to move horizontally on the first side plates 21.
