Description

Technical Field

[0001] This utility model relates to the field of battery cell sorting technology, specifically to a battery cell sorting device. Background Technology

[0002] After battery production is completed, the batteries need to be sorted and tested to ensure battery quality.

[0003] In related technologies, the battery sorting process typically involves manual collection, arrangement, and bagging of the cells, resulting in excessive human contact during the operation. Manual arrangement can easily cause friction between the cell grids, leading to surface scratches and affecting cell yield and efficiency. Additionally, there are some automated cell sorting machines, but their processing efficiency is relatively poor. Utility Model Content

[0004] This utility model aims to solve one of the technical problems in related technologies to a certain extent. To this end, this utility model provides a cell-forming device that improves the cell-forming efficiency and production efficiency, reduces scratches and breakage caused by human intervention, and increases the yield of battery cells.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a battery cell assembling device, the assembling device including a support frame and a storage component disposed on the support frame, the storage component including a bearing surface for supporting battery cells, the storage component being rotatably disposed on the support frame and capable of rotating and switching between a loading position and a sorting position, wherein in the loading position the bearing surface is horizontal; and in the sorting position the bearing surface forms a set angle with the horizontal plane; the assembling device further includes a purging component, the purging component being disposed on one side of the storage component in the sorting position, and used to purge the battery cells stored on the storage component using pressurized gas.

[0006] This embodiment can automatically sort the battery cells, and by setting a blowing component for blowing the battery cells at a position that forms an angle with the horizontal position (an inclined position) during the sorting process, the sorting efficiency and sorting quality can be improved.

[0007] Furthermore, the purging assembly includes a purging bracket, a purging drive unit, and at least one purging device. The purging device is disposed on the purging bracket, and the purging drive unit is used to drive the purging bracket to move closer to or away from the storage assembly in the sorting position. In the sorting position, the purging end of the purging device is opposite to the side of the battery cells stored in the storage assembly.

[0008] Furthermore, the purging assembly includes two purging nozzles, the purging ends of which face different directions. In the sorting position, the purging ends of the two purging nozzles are respectively opposite to the sides of the battery cells stored in the storage assembly in different directions.

[0009] Furthermore, the material storage assembly includes a material platform, a support plate disposed on the material platform, and multiple limiting plates. The material platform is rotatably disposed on the support frame. The top surface of the support plate is formed as the support surface. The limiting plates are respectively disposed on the first and second adjacent sides of the support plate. The third and fourth adjacent sides of the support plate are formed as feeding ports. The feeding ports are used to place the battery cells into the support plate. The limiting plates protrude from the support surface. The third side is opposite to the first side, and the second side is opposite to the fourth side. In the sorting position, the height of the first side of the support plate is lower than that of the third side.

[0010] Furthermore, at the sorting position, the purging assembly purifies the battery cells stored on the carrier plate from the third or fourth side.

[0011] Furthermore, the assembly also includes a first pressing unit, which is disposed on the material platform and located on one side of the support plate. The first pressing unit includes a first pressing plate and a first pressing drive, which drives the first pressing plate to switch between a blocking position and a non-blocking position. In the blocking position, the first pressing plate is opposite to the support surface and is used to block and limit the battery cells stored in the support unit; in the non-blocking position, the first pressing plate is offset from the support plate.

[0012] Furthermore, the storage assembly also includes a detection unit disposed on the support plate. The detection unit is used to send a pressing signal to the first pressing unit when there are battery cells on the support surface. Upon receiving the pressing signal, the first pressing unit switches the first pressing plate to the blocking position.

[0013] Furthermore, the assembly also includes a second pressing unit, which includes a second pressing plate and a second pressing drive. The second pressing plate is opposite to the bearing surface of the storage assembly in the sorting position. The second pressing drive is used to drive the second pressing plate to move closer to or away from the bearing surface in the direction opposite to the bearing surface of the storage assembly in the sorting position, and can control the looseness of the second pressing plate when pressing the battery cell.

[0014] Furthermore, the entire device includes a flip drive motor, which is disposed on the support frame and is used to drive the material storage component to rotate and switch between the feeding position and the sorting position.

[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described are intended to explain this utility model and should not be construed as limiting it.

[0020] The terms "an embodiment," "example," or "example" used in this specification refer to a particular feature, structure, or characteristic described in connection with the embodiment itself that may be included in at least one embodiment disclosed in this utility model. The phrase "in an embodiment" appearing in various places throughout the specification does not necessarily refer to the same embodiment.

[0021] One embodiment of this utility model discloses a battery cell assembly device, see attached drawing. Figure 1 To be continued Figure 4 The assembly includes a support frame 10 and a storage component 20 disposed on the support frame 10. The storage component 20 includes a bearing surface for supporting the battery cells. The storage component 20 is rotatably disposed on the support frame 10 and can rotate between a loading position and a sorting position. In the loading position, the bearing surface is horizontal; in the sorting position, the bearing surface forms a set angle with the horizontal plane. The assembly also includes a purging component 30, which is disposed on one side of the storage component 20 in the sorting position and is used to purge and sort the battery cells 80 stored on the storage component 20 using pressurized gas.

[0022] The cell-assembly device in this embodiment is used to organize the battery cells, improving their neatness and cleanliness, and facilitating subsequent packaging and bagging processes.

[0023] In this embodiment, the support frame 10 serves as the mounting base for the entire device. In actual installation, both the storage assembly 20 and the purging assembly 30 are mounted on the support frame 10. The storage assembly 20 is rotatably mounted on the support frame 10 and has a loading position and a sorting position. In the loading position, the bearing surface is horizontal, facilitating the placement of the battery cells onto the storage assembly 20. In the sorting position, the bearing surface forms a set angle with the horizontal plane, typically between 30° and 90°. (See attached diagram). Figure 4 In one embodiment of this utility model, the bearing surface is in a vertical state (forming a 90° angle with the horizontal plane) at the sorting position. The inclined setting of the bearing surface at the sorting position can automatically align multiple battery cells under their own weight, and also helps to remove impurities attached to the battery cells.

[0024] This embodiment does not specify the exact structure of the material storage component 20 for rotating between the feeding position and the sorting position. In actual setup, the material storage component 20 can be rotated directly by a motor (rotary drive component), or it can be rotated indirectly by a linear drive component combined with a transmission structure (such as a linkage mechanism).

[0025] The assembly device in this embodiment also includes a blowing component 30. When the storage component 20 is in the sorting position, the blowing component 30 can blow the battery cells stored on the storage component 20 (generally achieved by blowing air through the blower 32). This can cause the battery cells to vibrate, so that the battery cells can be more easily aligned under the action of the blowing force, avoiding the problem of misalignment caused by adhesion between adjacent battery cells. In addition, blowing can also clean the impurities attached to the surface of the battery cells, improving the cleanliness of the battery cell surface.

[0026] As one embodiment of this utility model, see the appendix. Figure 1 , 2 The purging assembly 30 includes a purging bracket 31, a purging drive unit, and at least one purging device 32. The purging device 32 is disposed on the purging bracket 31. The purging drive unit is used to drive the purging bracket 31 to move in a direction opposite to the bearing surface in the sorting position. In the sorting position, the purging end of the purging device 32 is opposite to the side of the battery cell stored in the storage assembly 20.

[0027] In this embodiment, the blower 32 blows the battery cell from the side, making it easier for the blown air to enter the gap between adjacent battery cells, thus making the cleaning of the battery cells more efficient.

[0028] In this embodiment, the purging bracket 31 can be moved away from the sorting position during the rotation of the storage component 20. This avoids interference and safety risks to the storage component 20 that may occur during the flipping process. After the storage component 20 is rotated into position, the purging bracket 31 can be moved to a position opposite to the side of the battery cell to perform the purging operation. In addition, the movable setting of the purging bracket 31 can fully purify battery cells of different stacking thicknesses, avoiding the problem that the side of the battery cell cannot be completely covered when the stacking thickness is thick, thus improving sorting efficiency and sorting quality.

[0029] As one embodiment of this utility model, see the appendix. Figure 2 The purging assembly 30 includes two purging nozzles 32, with the purging ends of the two purging nozzles 32 facing different directions. In the sorting position, the purging ends of the two purging nozzles 32 are respectively opposite to the sides of the battery cells stored in the storage assembly 20 in different directions.

[0030] The purging assembly 30 in this embodiment includes two purgers 32. For easy installation of the two purgers 32, please refer to the attached document. Figure 2 The blowing bracket 31 includes a first sliding arm 311 and a second sliding arm 314 that are spaced apart from each other. The two first sliding arms 311 and the second sliding arm 314 are connected by a first mounting arm 312 and a second mounting arm 313. The included angle between the first mounting arm 312 and the second mounting arm 313 is 90°. The first mounting arm 312 and the second mounting arm 313 are respectively parallel to the sides of the battery cell in different directions. Two blowers 32 are respectively installed on the first mounting arm 312 and the second mounting arm 313. In this way, the two blowers 32 are respectively opposite to the sides of the battery cell in two different directions, which can better blow the stacked battery cells and improve the overall efficiency.

[0031] The purging drive unit in this embodiment includes a first guide rail 33, a purging drive motor 34, and a first lead screw 35. There are two first guide rails 33, which are spaced apart. The first sliding arm 311 and the second sliding arm 314 are slidably mounted on the two first guide rails 33, respectively. The purging drive motor 34 is connected to one of the first sliding arms 311 and the second sliding arm 314 via the first lead screw 35 to drive the purging bracket 31 to slide along the first guide rail 33.

[0032] As one embodiment of this utility model, see the appendix. Figure 1 , 3 The material storage assembly 20 includes a material platform 21, a support plate 221 disposed on the material platform 21, and a plurality of limiting plates 23. The material platform 21 is rotatably disposed on the support frame 10. The top surface of the support plate 221 is formed as the support surface. The limiting plates 23 are respectively disposed on the first and second adjacent sides of the support plate 221. The third and fourth adjacent sides of the support plate 221 are formed as feeding ports. The feeding ports are used to place the battery cells into the support plate 221. The limiting plates 23 protrude from the support surface. The third side is opposite to the first side, and the second side is opposite to the fourth side. In the sorting position, the height of the first side of the support plate 221 is lower than that of the third side.

[0033] In this embodiment, the battery cell is loaded into the support plate 221 from the third and fourth open sides. The support plate 221 is used to support the bottom side of the battery cell at the loading position. At this time, the large surface of the bottom layer of the stacked battery cell is in contact with the support surface. The limiting plates 23 at the first and second sides limit the position of the battery cell.

[0034] When the material platform 21 rotates to the sorting position, the limiting plate 23 corresponding to the first side is located on the bottom side of the battery cell, serving as the main support component for the battery cell and preventing the battery cell from falling off.

[0035] In one embodiment of this utility model, at the sorting position, the purging assembly 30 purifies the battery cells stored on the carrier plate 221 from the third or fourth side.

[0036] See appendix Figure 1 In this embodiment, the blower 32 is positioned opposite to the third and fourth sides of the support plate 221. Since the third and fourth sides of the support plate 221 are open structures (without limit plate 23), the blower 32 can blow the battery cells stored on the support plate 221 and the limit plate 23 without obstruction.

[0037] As one embodiment of this utility model, see the appendix. Figure 1 , 3 The assembly also includes a first pressing unit 40, which is disposed on the material platform 21 and located on one side of the support plate 221. The first pressing unit 40 includes a first pressing plate 41 and a first pressing drive 42. The first pressing drive 42 is used to drive the first pressing plate 41 to switch between a blocking position and a non-blocking position. In the blocking position, the first pressing plate 41 is opposite to the support surface and is used to block and limit the battery cells stored in the support unit. In the non-blocking position, the first pressing plate 41 is offset from the support plate 221.

[0038] In this embodiment, the first pressing unit 40 is disposed on the material platform 21. When the material platform 21 is in the loading position (horizontal state), the battery cells are placed on the support plate 221. Since the rotation of the material platform 21 requires the battery cells to stand upright, if there is no structure to limit the battery cells from the top surface, the battery cells can easily fall off the support plate 221 during rotation. The first pressing unit 40 of this application includes a first pressing plate 41. After the battery cells are placed on the support plate 221, the first pressing plate 41 can extend to the top of the battery cells to block and limit the battery cells, thus preventing the battery cells from falling off during the rotation and standing process.

[0039] See appendix Figure 1 In this embodiment, the switching method of the first pressing plate 41 is set to rotation switching, and the first pressing drive 42 can be set as a rotary cylinder.

[0040] To improve the automation level of the entire device, the storage assembly 20 of one embodiment of the present invention further includes a detection unit 50. The detection unit 50 is disposed on the support plate 221. The detection unit 50 is used to send a pressing signal to the first pressing unit 40 when there are battery cells on the support surface. When the first pressing unit 40 receives the pressing signal, it switches the first pressing plate 41 to the blocking position.

[0041] In this embodiment, the detection unit 50 can sense the battery cell when it is placed on the support plate 221 and send a corresponding pressing signal. This pressing signal can control the first pressing plate 41 to automatically switch to the blocking position to block the top surface of the battery cell.

[0042] This embodiment does not specifically limit how the first pressure plate 41 switches between the blocking position and the non-blocking position. In actual settings, it can be set to switch by rotation or by sliding.

[0043] This embodiment does not specifically limit how the detection unit 50 senses or detects the battery cells. In actual setup, the detection unit 50 can be a photoelectric sensor, a proximity switch, or other structural electrical components that can sense objects.

[0044] As one embodiment of this utility model, see the appendix. Figure 1 , 2 The assembly also includes a second pressing unit 60, which includes a second pressing plate 61 and a second pressing drive. The second pressing plate 61 is opposite to the bearing surface of the storage assembly 20 in the sorting position. The second pressing drive is used to drive the second pressing plate 61 to move closer to or away from the bearing surface in the direction opposite to the bearing surface of the storage assembly 20 in the sorting position, and can control the looseness of the second pressing plate 61 when pressing the battery cell.

[0045] In this embodiment, the second pressing unit 60 is used to press and limit the battery cell at the sorting position. It should be noted that in actual setup, the first pressing unit 40 and the second pressing unit 60 press the battery cell from the same direction. The first pressing unit 40 and the second pressing unit 60 can coexist, but they can be used in coordination. For example, during the flipping process, the first pressing unit 40 ensures the stability of the battery cell. After flipping to the whole cell position, the first pressing plate 41 can switch to a non-blocking position (when the second pressing plate 61 is close to the battery cell). At this time, the second pressing plate 61 replaces the blocking effect of the first pressing plate 41 on the battery cell.

[0046] In this embodiment, the second pressing plate 61 can adjust the pressure on the battery cells during use, that is, it can adjust the looseness of the stacked battery cells.

[0047] In this embodiment, the second driving component includes a second driving motor 64, a second guide rail 62, and a second lead screw 63. In actual installation, the second pressure plate 61 can be slidably mounted on the second guide rail 62 via a slider. The second driving motor 64 is connected to the slider via the second lead screw 63 to drive the second pressure plate 61 to reciprocate along the second guide rail 62.

[0048] In actual setup, the purging assembly 30 and the second pressing unit 60 work together to achieve multiple purgings of the battery cells under different looseness conditions, thereby improving the sorting effect and sorting quality.

[0049] It is conceivable that, in actual setup, the first pressing unit 40 and the second pressing unit 60 can be combined. Specifically, the first pressing plate 41 can be made to move in the direction opposite to the bearing surface. That is, the first pressing plate 41 can rotate to switch between the blocking position and the non-blocking position, and can also adjust the looseness of the battery cells, so that it also has the function of the second pressing plate 61. Specifically, it only needs to be designed accordingly in the drive structure, which will not be elaborated here.

[0050] As one embodiment of the present invention, the whole piece device includes a flip drive motor 70, which is disposed on the support frame 10. The flip drive motor 70 is used to drive the material storage component 20 to rotate and switch between the feeding position and the sorting position.

[0051] The above are merely specific embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Those skilled in the art should understand that this utility model includes, but is not limited to, the contents described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of this utility model will be included within the scope of the claims.
