Description

[Technical Field]

[0001] This utility model belongs to the field of battery cell manufacturing technology, and in particular relates to a highly compatible battery cell sorting and feeding box. [Background Technology]

[0002] After manufacturing, solar cells need to undergo photoelectric conversion efficiency (IV) testing, a process known in the industry. Following IV testing, cells are sorted and unloaded based on their photoelectric conversion efficiency. Sorting bins are used for this process; for example, patent CN219092814U discloses an automatic bin-organizing mechanism for a battery testing and sorting machine, and patent CN219497737U discloses a solar cell bin. Cells with photoelectric conversion efficiency within the same set range are stacked and stored in the same sorting bin, then transported to the unloading end where they are picked up by a handling mechanism for packaging. The sorting bin then returns to the sorting station to receive more solar cells, achieving recycling.

[0003] With the widespread application of solar cells, cell sizes vary. When cell size changes, all the cell bins need to be replaced, resulting in high replacement costs. Existing patent CN220691983U discloses a cell bin that can be adapted to various cell sizes by flexibly adjusting the position of the baffles. However, for sorting bins, which are generally one-piece molded structures, the baffles cannot be flexibly adjusted, therefore this method is not applicable.

[0004] Therefore, it is necessary to provide a new, highly compatible cell sorting and feeding box to solve the above-mentioned technical problems. [Utility Model Content]

[0005] The main purpose of this utility model is to provide a highly compatible battery cell sorting and selection box that can be compatible with various battery cells of different sizes, has strong versatility, and greatly reduces the cost of battery cell replacement.

[0006] This utility model achieves the above-mentioned objective through the following technical solution: a highly compatible battery cell sorting and selection box, which includes a box body and several quick-change blocks installed on the inner wall surface of the box body; the box body includes a bottom plate and several baffles extending vertically upward from the edge of the bottom plate, and the baffles and the bottom plate together form an upward-opening storage groove.

[0007] Furthermore, the enclosure includes a pair of long side enclosures and a pair of short side enclosures. The short side enclosures and / or the inner surface of the short side enclosures are provided with vertically extending locking grooves. The back of the shape-changing block is provided with a locking strip that cooperates with the locking grooves to achieve tight fastening.

[0008] Furthermore, the shape-changing blocks are arranged in pairs on opposite sides of the material box body.

[0009] Furthermore, the bottom of the storage slot is an inclined surface.

[0010] Furthermore, the thickness of the base plate varies along its long side, wherein the thickness of the front end of the base plate is less than the thickness of the rear end.

[0011] Furthermore, the material box body is provided with a material removal clearance notch to facilitate the entry of the battery cell clamping claws into and support the bottom of the battery cell stack.

[0012] Furthermore, the material picking avoidance notch includes a pair of first material picking avoidance notches formed on both sides of the long side of the material box body and a pair of second material picking avoidance notches formed on both sides of the short side of the material box body; the first material picking avoidance notch extends from the top of the long side enclosure to a predetermined length on the bottom plate; the second material picking avoidance notch extends from the top of the short side enclosure to a predetermined length on the bottom plate.

[0013] Furthermore, a first number mark is provided on the top of the enclosure plate corresponding to the position of the latch groove, and a corresponding second number mark is provided on the top of the shape-changing block.

[0014] Furthermore, the top of the enclosure is provided with a directional indicator indicating the front and rear directions; the bottom of the base plate is provided with an installation groove, several positioning holes and several weight reduction grooves, and a readable device is provided in the installation groove.

[0015] Furthermore, the replacement block is installed on the inner wall surface of the enclosure panel using adhesive, screw fastening, or plug-in methods.

[0016] Compared with the prior art, the advantages of this utility model of a highly compatible battery cell sorting box are as follows: a quick-changeable shape-changing block is set on the inner surface of the baffle plate, and the size of the storage slot is changed by the thickness of the shape-changing block to accommodate battery cells of various sizes, which greatly improves the compatibility of the box; when changing the shape of the battery cells, there is no need to replace the box body, only the shape-changing block needs to be replaced, which greatly reduces the changeover cost.

Detailed Implementation Methods

[0026] Example 1:

[0027] Please refer to Figures 1-4 This embodiment is a highly compatible battery cell sorting box 100, which includes a box body 1 and several quick-change blocks 2 installed on the inner wall surface of the box body 1.

[0028] The material box body 1 is an integral structure, including a base plate 11 and several baffles 12 extending vertically upward from the edge of the base plate 11. The baffles 12 and the base plate 11 together form an upward-opening storage groove 13.

[0029] The enclosure 12 includes a pair of long-side enclosures 121 and a pair of short-side enclosures 122. The inner surface of the short-side enclosures 122 has a vertically extending locking groove 1221. The back of the changing block 2 has a locking strip 21 that engages with the locking groove 1221 for a tight fastening installation. During installation, the bottom of the locking strip 21 is aligned with the top of the locking groove 1221, and then slid down along the locking groove 1221 to install the changing block 2 onto the material box body 1. After the changing block 2 is installed onto the short-side enclosures 122, one side surface of the changing block 2 forms a new enclosure limiting surface against the short side of the battery cell 200, reducing the short-side dimension of the storage groove 13, thus making it suitable for storing small-sized battery cells. Depending on the type and specifications of the battery cells, various thicknesses of the changing block 2 can be designed.

[0030] The changing block 2 can be installed on only one side of the short side baffle 122, or it can be installed in pairs on both sides of the short side baffle 122. Since the material box body 1 is shared by both small and large battery cells in the sorting equipment, the center position of the material box is fixed. In order to facilitate the operation of the handling robot of the sorting equipment without adjusting the running coordinates after the battery cell is changed, the changing block 2 is preferably installed in pairs on two opposite short side baffles 122.

[0031] To facilitate the alignment of the battery cells within the storage slot 13, the bottom of the storage slot 13 is sloped. Specifically, the material box body 1 has a front end and a rear end distributed along its long side, denoted as end A and end B, with end A of the bottom of the storage slot 13 being lower and end B being higher. In this embodiment, the thickness of the base plate 11 varies along its long side, with end B of the base plate 11 being thicker than end A, thus making the bottom of the storage slot 13 sloped. After the battery cells are placed into the storage slot 13, due to the presence of the sloped surface, the battery cells will move forward under their own weight and abut against the inner wall of the front enclosure of the storage slot 13.

[0032] After the material box is filled with a set number of battery cells, to facilitate the removal of the entire battery cell stack 200, the material box body 1 is provided with a material removal clearance notch 14 to allow the battery cell grippers to enter and support the bottom of the battery cell stack 200. The material removal clearance notch 14 includes a pair of first material removal clearance notches 141 on both sides of the long side of the material box body 1 and a pair of second material removal clearance notches 142 on both sides of the short side of the material box body 1. The first material removal clearance notches 141 extend from the top of the long side enclosure 121 to a set length on the bottom plate 11. The second material removal clearance notches 142 extend from the top of the short side enclosure 122 to a set length on the bottom plate 11. The battery cell grippers extend from all sides of the material box body 1 into the storage slot 13, supporting the battery cell stack 200 from the bottom and restricting the four edges of the battery cell stack 200, thus effectively and reliably gripping the battery cell stack 200.

[0033] To facilitate quick and correct installation of the interchangeable block 2, a first number identifier 1222 is provided on the short side enclosure 122 corresponding to the position of the locking slot 1221. Each locking slot 122 corresponds to a unique first number identifier 1222, and a corresponding second number identifier 22 is provided on the top of the interchangeable block 2. When installing multiple interchangeable blocks 2, the interchangeable block 2 can be installed in the locking slot 122 with the same number as the first number identifier 1222 and the second number identifier 22 to prevent installation errors.

[0034] When the material box is placed into the sorting equipment, there is a front and a back. Therefore, the material box needs to be placed in the correct direction. In order to prevent the material box from being placed in the wrong direction, the top of the material box is equipped with a direction indicator 15 to indicate the front and back direction.

[0035] The material boxes are transported to multiple working positions in the sorting equipment, and they need to be numbered during the recycling process so that the system can accurately know the location of the material boxes and the information of the battery cells they carry. In order to facilitate the identification and recording of the material boxes by the sorting system, the bottom of the base plate 11 is provided with a mounting groove 111, and a readable device (not shown in the figure), such as an electronic tag, is installed in the mounting groove 111.

[0036] Since the material box will undergo a lifting process in the sorting equipment, in order to facilitate the lifting device to accurately lift the material box upward and to facilitate the accurate positioning of the material box in the conveying device, the bottom of the base plate 11 is also provided with several positioning holes 112.

[0037] To reduce the weight of the material box, the bottom of the base plate 11 is also provided with several weight-reducing grooves 113.

[0038] Example 2:

[0039] This embodiment has a structure that is basically the same as that of Embodiment 1, except that the shape-changing block 2 is set on the inner surface of the long side enclosure 121.

[0040] Example 3:

[0041] This embodiment has a structure that is basically the same as that of Embodiment 1, except that: a shape-changing block 2 is installed on the inner surface of both the long side enclosure 121 and the short side enclosure 122.

[0042] Example 4:

[0043] This embodiment has a structure that is basically the same as that of Embodiment 1. The difference is that the replacement block 2 is installed on the inner wall surface of the enclosure 12 by means of adhesive, screw fastening or plugging.

[0044] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
