[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model.

[0035] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0036] Example 1

[0037] refer to Figures 1 to 4 The battery cell sorting equipment provided in this embodiment includes a pushing mechanism 1, a sorting mechanism 2, and a discharging mechanism 3 arranged sequentially. The pushing mechanism 1 is used to push the battery cells from the sorting mechanism 2 to the discharging mechanism 3, and the discharging mechanism 3 is used to discharge qualified battery cells. In this embodiment, when the battery cell is placed on the sorting mechanism 2, the battery cell is in a flat state, and the pushing mechanism 1 moves the battery cell from the sorting mechanism 2 to the discharging mechanism 3 by pushing the head or bottom of the battery cell.

[0038] The sorting mechanism 2 includes a cell rotation unit 21, a barcode scanning and identification unit 22 disposed above the cell rotation unit 21, and a defective product storage bin 23 disposed below the cell rotation unit 21. The cell rotation unit 21 includes a first drive assembly 211, a first roller assembly 212, a second drive assembly 213, and a second roller assembly 214. The first roller assembly 212 abuts against the second roller assembly 214. The first drive assembly 211 is used to drive the first roller assembly 212 to rotate, and the second drive assembly 213 is used to drive the second roller assembly 214 to move closer to or away from the first roller assembly 212.

[0039] During operation, the first roller assembly 212 and the second roller assembly 214 abut against each other, and the battery cell is placed at the abutment point of the first roller assembly 212 and the second roller assembly 214. When the first drive assembly 211 drives the first roller assembly 212 to rotate, the second roller assembly 214 will rotate synchronously with the first roller assembly 212 under the drive of the first roller assembly 212, thereby causing the battery cell to rotate. During the rotation of the battery cell, the battery cell code on the battery cell will be exposed below the barcode scanning and identification unit 22 for scanning and identification by the barcode scanning and identification unit 22. If the barcode scanning and identification unit 22 identifies that the battery cell meets the assembly requirements, it pushes the battery cell to the unloading mechanism 3 through the pushing mechanism 1; if the barcode scanning and identification unit 22 identifies that the battery cell does not meet the requirements, it drives the second roller assembly 214 away from the first roller assembly 212 through the second drive assembly 213, so that the unqualified battery cell falls into the unqualified product storage bin 23. The cooperation between the first roller assembly 212 and the second roller assembly 214 not only assists the barcode scanning and identification unit 22 in scanning and identifying battery cells, but also allows the barcode scanning and identification unit 22 to directly discharge unqualified battery cells to the unqualified product storage bin 23 when identifying them. This improves the efficiency of battery sorting, effectively increasing production efficiency, while also simplifying the equipment structure and effectively reducing production costs.

[0040] In some embodiments, the first drive assembly 211 includes a first drive motor 2111 and a first transmission belt 2112. The first transmission belt 2112 is connected between the drive end of the first drive motor 2111 and the first roller assembly 212, and drives the first roller assembly 212 to rotate under the drive of the first drive motor 2111. In this embodiment, the second drive assembly 213 is a horizontal drive cylinder.

[0041] The battery cell sorting equipment in this embodiment, through the cooperation of the first roller assembly and the second roller assembly, can both scan and identify the battery cells and discharge unqualified battery cells, thereby improving the efficiency of battery sorting and production efficiency. At the same time, it simplifies the equipment structure and reduces production costs. The first roller assembly is driven to rotate by the first drive motor, which in turn drives the second roller assembly to rotate, saving power costs and further reducing production costs.

[0042] Example 2

[0043] As a further optimization of Example 1, refer to Figure 5 and 6 The feeding mechanism 3 includes a feeding trough 31 and a qualified product storage bin 32 located below the feeding trough 31. The feeding trough 31 is arranged adjacent to the first roller assembly 212 and the second roller assembly 214. Specifically, the feeding trough 31 is located downstream of the contact point between the first roller assembly 212 and the second roller assembly 214. Qualified battery cells are moved from the contact point between the first roller assembly 212 and the second roller assembly 214 to the feeding trough 31 under the pushing force of the feeding mechanism 1, and then slide from the feeding trough 31 into the qualified product storage bin 32.

[0044] As a further optimization, a first guide slope 311 is formed at the bottom of the feeding trough 31. The first guide slope 311 is used to guide qualified battery cells into the qualified product storage bin 32. When the qualified battery cells reach the feeding trough 31, they can tilt downwards under the action of gravity and move downwards along the first guide slope 311, and finally fall naturally into the qualified product storage bin 32.

[0045] In this embodiment, the battery cell sorting equipment includes only a feeding trough and a qualified product storage bin in its feeding mechanism. It does not have a power component for driving the feeding action, which saves power costs and reduces production costs. By setting a first guide slope in the feeding trough, qualified battery cells can be further promoted to slide down into the qualified product storage bin under the action of gravity, which helps to improve the feeding operation efficiency and thus improve production efficiency.

[0046] Example 3

[0047] As a further optimization of Example 2, refer to Figures 7 to 11 The battery cell sorting equipment also includes a feeding mechanism 4, which includes a feeding trough 41 and a feeding bin 42 located above the feeding trough 41. The bottom of the feeding bin 42 has an opening, and a sorting unit 43 is provided at the opening of the feeding bin 42. The sorting unit 43 is used to transfer the battery cells in the feeding bin 42 into the feeding trough 41. The feeding trough 41 is located between the pushing mechanism 1 and the sorting mechanism 2. Specifically, the feeding trough 41 is located upstream of the contact point between the first roller assembly 212 and the second roller assembly 214.

[0048] In this embodiment, the sorting unit 43 transfers one battery cell from the loading bin 42 to the loading trough 41 each time. Then, the pushing mechanism 1 pushes the battery cell from the loading trough 41 to the sorting mechanism 2. At this time, the sorting unit 43 continues to transfer battery cells to the loading trough 41. When the barcode scanning unit 22 identifies a qualified battery cell, the pushing mechanism 1 pushes the battery cell from the loading trough 41 to the sorting mechanism 2, indirectly pushing the battery cell originally located in the sorting mechanism 2 into the unloading trough 31. Finally, under gravity, it slides down into the qualified product storage bin 32. Driven by the pushing mechanism 1, both battery cell transfer and unloading are achieved simultaneously. The single driving action of the pushing mechanism 1 realizes both the transfer and unloading operations. This improves the efficiency of battery cell sorting, saves power costs, and helps improve production efficiency.

[0049] In some embodiments, the sorting unit 43 includes a sorting roller 431 and a third drive assembly 432 for driving the sorting roller 431 to rotate. The outer wall of the sorting roller 431 is provided with a plurality of cell receiving slots 4311 circumferentially. The size and shape of the cell receiving slots 4311 match the size and shape of the cells to be sorted, and each cell receiving slot 4311 can accommodate one cell. Since the sorting roller 431 is located at the bottom of the feeding bin 42, the cells located in the feeding bin 42 will naturally fall into the cell receiving slots 4311 under gravity. With the rotation of the sorting roller 431, the cells located in the cell receiving slots 4311 will be moved to the opening of the feeding bin 42 and fall out from the opening of the feeding bin 42 into the feeding trough 41. The automated sorting and feeding by the sorting unit 43 eliminates the need for manual feeding, and the feeding accuracy is high, with controllable feeding speed, which helps improve the quality and efficiency of cell sorting operations.

[0050] As a further optimization, a second guide slope 421 is formed at the bottom of the feeding bin 42. The second guide slope 421 is used to guide the battery cells located in the feeding bin 42 into the battery cell receiving groove 4311. It can be understood that the bottom wall of the feeding bin 42 is inclined towards the sorting roller 431, so that the battery cells located in the feeding bin 42 gather on the top of the sorting roller 431 under the action of gravity, so that the battery cells fall into the battery cell receiving groove 4311 in time, thereby further improving the feeding efficiency of the battery cells, and thus improving the sorting efficiency of the battery cells.

[0051] In this embodiment, the third drive assembly 432 includes a second drive motor 4321 and a second transmission belt 4322. The second transmission belt 4322 is connected between the drive end of the second drive motor 4321 and the sorting roller 431. Under the drive of the second drive motor 4321, the sorting roller 431 is rotated through the second transmission belt 4322.

[0052] In some embodiments, the sorting unit 43 further includes a positioning sensor component 433, which is used to position the rotation of the sorting roller 431. In this embodiment, the positioning sensor component 433 is an optical positioning sensor. By setting an optical positioning sensor, the rotation distance of the sorting roller 431 can be accurately detected and a signal can be sent to the third drive component 432, causing the third drive component 432 to control the sorting roller 431 to stop rotating at a set rotation distance, so that the battery cells located in the battery cell receiving slot 4311 can accurately fall into the feeding slot 41, thereby improving the accuracy of the feeding operation and thus improving the quality of battery cell production.

[0053] In some embodiments, the pushing mechanism 1 includes a push block 11 and a drive unit 12 for driving the push block 11 forward or backward. The push block 11 may be cylindrical to match the shape of the head or bottom of the battery cell, and the drive unit 12 may be a drive cylinder.

[0054] In this embodiment, the specific operation process of the battery cell sorting equipment is as follows: the sorting roller 431 moves the battery cells from the loading bin 42 to the loading trough 41, and the pushing mechanism 1 pushes the battery cells in the loading trough 41 to the contact point between the first roller assembly 212 and the second roller assembly 214; the first roller assembly 212 and the second roller assembly 214 rotate synchronously, exposing the battery cell code to the barcode scanning and identification unit 22, which scans and identifies the battery cell code; if the battery cell is identified as unqualified, the first roller assembly 212 moves to the contact point between the first roller assembly 212 and the second roller assembly 214. The second drive assembly 213 drives the second roller assembly 214 away from the first roller assembly 212, causing the defective battery cells to fall into the defective product storage bin 23. If the battery cell is identified as qualified, the pusher mechanism 1 continues to push the battery cell located in the feeding trough 41 to the contact point between the first roller assembly 212 and the second roller assembly 214, causing the qualified battery cell originally located at the contact point between the first roller assembly 212 and the second roller assembly 214 to be indirectly pushed into the unloading trough 31, and finally fall into the qualified product storage bin 32.

[0055] The battery cell sorting equipment in this embodiment achieves automated and precise feeding of battery cells by setting up a sorting unit, thereby improving the quality of the feeding operation. By setting up a sorting roller, the feeding accuracy is further improved, and the feeding speed is controllable, which is conducive to improving the quality and efficiency of battery cell sorting. By setting up a second guide slope, the feeding efficiency of battery cells is further improved, thereby improving the efficiency of battery cell sorting. By setting up a positioning sensing component, the operating accuracy of the sorting roller is further improved, thereby improving the quality of battery cell production.
