[0021] The aforementioned improved technical features can be combined with each other as long as they do not conflict with each other.
[0022] In summary, the beneficial effects of the above-described technical solutions conceived by this utility model compared with the prior art include:
[0023] In the battery cell sorting mechanism provided in this embodiment of the present invention, when sorting battery cells, firstly, a battery cell conveyor line sequentially conveys multiple battery cells along a first direction. Then, a first displacement module drives a suction cup to move. After the suction cup moves directly above the battery cell, it performs vacuum adsorption, causing the battery cell to detach from the battery cell conveyor line and move to the material box on the support rod. By releasing the vacuum, the battery cell falls into the empty material box. The above steps are repeated until the material box is full of battery cells, forming a full material box. Next, a second displacement module drives a lifting module and a support platform to move along a second direction to below the corresponding full material box (at this time, the support platform is below the two first material box conveyor belts, and the first material box conveyor belts are located below the support rod). The lifting module drives the support platform to move upward, making the support platform higher than the first material box conveyor belts. The rotation module then drives the support platform to rotate 90° clockwise (or 90° counterclockwise). The lifting module then drives the support platform to continue rising until the support platform supports the full material box and is higher than the support part, causing the full material box to detach from the support part. Subsequently, the second displacement module drives the support platform to move along the second direction, causing the full material box to be misaligned with the support part. Correspondingly, the lifting module drives the support platform and the material box to move down between the first material box conveyor belt and the support rod, and drives the support platform and the full material box to rotate counterclockwise by ° through the rotation module. After that, the lifting module drives the support platform and the material box to continue to move down, so that the full material box is placed on the first material box conveyor belt. At this time, the width direction of the full material box is arranged along the first direction, while the support platform continues to move down to the initial position, causing the support platform to detach from the full material box.
[0024] Finally, the second displacement module drives the support platform to move along the second direction, aligning the two first material box conveyor belts with the material box conveyor line. The two first material box conveyor belts transport full boxes along the first direction to the material box conveyor line, which then transports the full boxes downstream and feeds empty boxes to the two first material box conveyor belts via the material box conveyor line. Specifically, the two first material box conveyor belts transport empty boxes along the first direction to above the support platform. The second displacement module drives the support platform to move along the second direction, causing the empty boxes to be misaligned with the corresponding support parts on the support rods in the second direction, preventing interference with the support parts during the subsequent upward movement of the empty boxes. Next, the lifting module first drives the empty boxes above the two first material box conveyor belts, and the rotation module then drives the empty boxes to rotate 90°. Afterward, the lifting module drives the empty boxes to move upward until they are above the support rods. The second displacement module drives the support platform to move along the second direction, positioning the empty material box directly above the corresponding support. Finally, the lifting module drives the support platform to move downwards, causing the empty material box to fall onto the support. The support platform then descends, rotates to reset, and finally returns to its initial position, completing the transport of the empty material box. At this point, the empty material box can receive solar cells again. This process is repeated to transport full and empty material boxes, thus completing the sorting of each solar cell.
[0025] Correspondingly, the material box transfer module is located below the material box carrying module, and the battery cell transfer module is located above the battery cell conveyor line and the material box carrying module, achieving a multi-layered arrangement that avoids excessive horizontal space occupation and makes the structure more compact. Furthermore, in this sorting mechanism, the battery cell conveyor line, the first material box belt conveyor, and the material box conveyor line all extend in the same direction, achieving a parallel arrangement of multiple conveyor lines in the same direction, thereby further reducing space occupation and making the overall structure more compact.
[0026] In other words, the battery cell sorting mechanism provided in this embodiment of the utility model can make the overall structure of the sorting mechanism compact and occupy little space during the process of sorting and recycling battery cells. Attached Figure Description

[0052] The cell conveying line 1 extends along a first direction (e.g., the X-axis direction). The cell conveying line 1 is used to convey cells, and the length direction of the cells is arranged along the first direction (i.e., a1 or a2 is arranged along the first direction).

Figure 7 As shown, the material box carrying module 2 includes two support rods 21 arranged at intervals along a first direction.

Figure 8 As shown, the cell transfer module 3 is located above the cell conveying line 1 and the material box carrying module 2. The cell transfer module 3 includes a first displacement module 31 and a suction cup 32. The first displacement module 31 is used to drive the suction cup 32 to move along the second direction. The suction cup 32 is used to adsorb the cell to transfer the cell on the cell conveying line 1 to the material box.
[0055] Figure 9 This is a structural schematic diagram of the material box transfer module provided in this embodiment of the utility model. Figure 10 This is a partial schematic diagram of the material box transfer module provided in this embodiment of the utility model, combined with... Figure 9 and Figure 10 As shown, the material box transfer module 4 is located below the material box carrying module 2. The material box transfer module 4 includes a second displacement module 41, a lifting module 42, a rotation module 43, a support platform 44, and two first material box conveyor belts 45 arranged at intervals along a second direction. The second displacement module 41 is used to drive the lifting module 42 and the two first material box conveyor belts 45 to move along the second direction. The lifting module 42 is used to drive the rotation module 43 to lift along a third direction (e.g., the Z-axis direction). The rotation module 43 is used to drive the support platform 44 to rotate. The support platform 44 is arranged horizontally and located between the two first material box conveyor belts 45. The support platform 44 is used to support the material box. Each first material box conveyor belt 45 extends along a first direction. The two first material box conveyor belts 45 respectively support the two ends of the material box in the length direction and transport the material box. The lifting module 42 can be an electric cylinder, and the rotation module 43 can be a rotary electric cylinder.
[0056] The connecting module 5 includes a box conveyor line 51, which extends along a first direction. The box conveyor line 51 is used to convey empty boxes to two first box conveyor belts 45 and to receive full boxes conveyed by the two first box conveyor belts 45. The first direction and the second direction are two perpendicular directions in the horizontal plane, and the third direction is a vertical direction.
[0057] In the battery cell sorting mechanism provided in this embodiment of the present invention, when sorting battery cells, firstly, the battery cell conveyor line 1 sequentially conveys multiple battery cells along a first direction. Initially, the suction cup 32 is located above the battery cell conveyor line 1 and is in a waiting state. After being directly above the battery cell, it performs vacuum adsorption, causing the battery cell to detach from the battery cell conveyor line 1. The first displacement module 31 drives the suction cup 32 to move, and moves the battery cell to the material box on the support rod 21. By releasing the vacuum, the battery cell falls into the empty material box. The first displacement module 31 and the suction cup 32 return to the initial position to wait. The above steps are repeated until the material box is full of battery cells, forming a full material box. Next, the second displacement module 41 drives the lifting module 42 and the support platform 44 to move along the first and second directions to below the corresponding full material box (at this time, the support platform 44 is below the two first material box conveyor belts 45, and the first material box conveyor belts 45 are located below the support rod 21). The lifting module 42 drives the support platform 44 to move upward, so that the support platform 44 is higher than the first material box conveyor belts 45. The rotation module 43 then drives the support platform 44 to rotate 90° clockwise (or 90° counterclockwise). The lifting module 42 then drives the support platform 44 to continue to rise until the support platform 44 supports the full material box and is higher than the support part 22, so that the full material box is detached from the support part 22. After that, the second displacement module 41 drives the support platform 44 to move along the second direction, so that the full material box is misaligned with the support part 22. Correspondingly, the lifting module 42 drives the support platform 44 and the material box to move down between the first material box conveyor belt 45 and the support rod 21, and drives the support platform 44 and the full material box to rotate counterclockwise by 90° through the rotation module 43. After that, the lifting module 42 drives the support platform 44 and the material box to continue to move down, so that the full material box is placed on the first material box conveyor belt 45. At this time, the width direction of the full material box is arranged along the first direction (i.e., b1 or b2 is arranged along the first direction), while the support platform 44 continues to move down to the initial position, so that the support platform 44 detaches from the full material box.
[0058] Finally, the second displacement module 41 drives the support platform 44 to move along the second direction, so that the two first material box conveyor belts 45 are aligned with the material box conveyor line 51. The two first material box conveyor belts 45 transport full material boxes along the first direction to the material box conveyor line 51, and the material box conveyor line 51 transports the full material boxes downstream and transports empty material boxes to the two first material box conveyor belts 45 via the material box conveyor line 51. Specifically, the two first material box conveyor belts 45 transport empty material boxes above the support platform 44 along the first direction, and the second displacement module 41 drives the support platform 44 to move along the second direction, so that the empty material box is misaligned with the corresponding support part 22 on the support rod 21 in the second direction, avoiding interference with the support part 22 during the subsequent upward movement of the empty material box. Next, the lifting module 42 first drives the empty material box above the two first material box conveyor belts 45, and the rotation module 43 drives the empty material box to rotate 90°. After that, the lifting module 42 drives the empty material box to move upward and the empty material box is above the support rod 21. The second displacement module 41 drives the support platform 44 to move along the second direction, so that the empty material box is directly above the corresponding support part 22. Finally, the lifting module 42 drives the support platform 44 to move down, so that the empty material box falls on the support part 22. The support platform 44 then descends, rotates to reset, and finally descends to its initial position, thus completing the conveying of the empty material box. At this time, the empty material box can receive solar cells again. In this way, the sorting of each solar cell can be completed by conveying full and empty material boxes. It should be noted that the above description is based on the transfer of a material box at one position. In actual operation, according to the different grades of solar cells, the solar cell transfer module 3 transfers the solar cells to different corresponding material boxes. When a material box is full, the transfer of the currently full material box and the replenishment of the empty material box are carried out.
[0059] A battery cell sorting mechanism is provided in this utility model embodiment. A material box carrying module 2 is disposed on one or both sides of the battery cell conveying line 1, and a connecting module 5 is disposed at the discharge end of the battery cell conveying line 1. The battery cell conveying line 1, the first material box belt 45, and the material box conveying line 51 all extend in the same direction, achieving a parallel arrangement of multiple conveying lines in the same direction, thereby reducing space occupation and making the overall structure more compact.
[0060] Correspondingly, the material box transfer module 4 is located below the material box carrying module 2, and the battery cell transfer module 3 is located above the battery cell conveying line 1 and the material box carrying module 2, realizing a multi-junction layered arrangement, avoiding excessive space occupation in the horizontal direction, and making the structure more compact.
[0061] In other words, the battery cell sorting mechanism provided in this embodiment of the utility model can make the overall structure of the sorting mechanism compact and occupy little space during the process of sorting and recycling battery cells.
[0062] For example, when conveying half of the battery cell 101, the two half of the battery cell 101 are conveyed side by side in the second direction, thereby increasing the conveying efficiency.
[0063] It is easy to understand that the material box transfer module 4 can rotate the material box, so that when the material box is placed on the first material box conveyor belt 45, its two ends in the length direction are always placed on the corresponding first material box conveyor belt 45 (that is, the width direction of the material box is always consistent with the length direction of the first material box conveyor belt 45). This can accommodate the conveying of half material boxes 201. The material box transfer module 4 can also accommodate the conveying of whole material boxes 202. During the material box transfer, rotation is not required, achieving compatible efficiency. Correspondingly, at this time, the support part 22 can support both half material boxes 201 and whole material boxes 202 (or different support parts 22 can support material boxes of different sizes).
[0064] For example, the cell conveyor line 1 includes a drive motor 12, a drive pulley 13, a driven pulley 14, and a synchronous belt 15. The drive motor 12 is connected to the drive pulley 13, and the synchronous belt 15 is wound around the drive pulley 13 and the driven pulley 14. A reflection sensor is provided above the synchronous belt 15, and a reflective sticker matching the reflection sensor is provided on the synchronous belt 15, thereby realizing the zero-return calibration of the synchronous belt 15.
[0065] In one embodiment of this utility model, the support platform 44 has a plurality of spaced positioning protrusions 441, each positioning protrusion 441 being movably inserted into the positioning groove corresponding to the material box. Thus, the cooperation between the positioning protrusions 441 and the positioning groove can ensure the reliability of the material box's arrangement on the support platform 44, and prevent the material box from moving off or falling off the support platform 44 during the rotation of the support platform 44.
[0066] For example, the number of positioning protrusions 441 can be four, arranged at intervals, and the top of the positioning protrusions 441 is a conical structure, which facilitates quick insertion into the positioning groove.
[0067] In this embodiment, a set of limiting blocks is provided on the battery cell conveying line 1. Each set of limiting blocks includes multiple limiting blocks 11 arranged at intervals. The multiple limiting blocks 11 are used to accommodate and position the battery cells. The positioning of the battery cells during the conveying process of the battery cell conveying line 1 can be achieved through the multiple limiting blocks 11.
[0068] Furthermore, the limiting block group is detachably set on the cell conveying line 1. Multiple limiting blocks 11 are used to accommodate and position half cell 101 or whole cell 102, thereby enabling the positioning of cells of different sizes by assembling and disassembling the limiting blocks 11, thus making it compatible with cells of different sizes and types.
[0069] Figure 11This is a schematic diagram of the arrangement of a limiting block assembly provided in an embodiment of this utility model, as shown below. Figure 11 As shown, the limiting block group includes four limiting blocks 11, each of which is L-shaped. The four limiting blocks enclose a first space for accommodating half-cell batteries 101. Correspondingly, when conveying half-cell batteries 101, two limiting block groups are arranged side-by-side in the width direction of the battery cell conveying line 1. It should be noted that during the sorting of half-cell batteries, two half-cell batteries 101 are conveyed side-by-side in a second direction. Correspondingly, two limiting block groups are arranged in the second direction to position the two battery cells respectively.
[0070] Figure 12 This is a schematic diagram of the arrangement of a limiting block assembly provided in an embodiment of this utility model, as shown below. Figure 12 As shown, the limiting block group includes four limiting blocks 11, each of which is L-shaped. The four limiting blocks 11 surround a second space, which is used to accommodate the entire battery cell 102.
[0071] In other words, when it is necessary to transport the entire battery cell 102, the limit block assembly adopts... Figure 12 The arrangement of the limit blocks; when it is necessary to transport half of the battery cell 101, the limit block group adopts... Figure 11 The layout.
[0072] For example, each limiting block 11 can be detachably connected by bolts.
[0073] In addition, each support part 22 is detachably arranged on the support rod 21, and each support part 22 includes a plurality of support blocks 221 respectively disposed on the two support rods 21.
[0074] It is easy to understand that when supporting a half-piece material box 201 is required, multiple support blocks 221 are installed to form a first support surface, which can support the half-piece material box 201. When supporting a full-piece material box 202 is required, multiple support blocks 221 are installed to form a second support surface, which can support the full-piece material box 202, thus achieving compatibility in supporting material boxes of different sizes. In addition, the bottom of both the half-piece material box 201 and the full-piece material box 202 has grooves, and each support block 221 is inserted into the corresponding groove.
[0075] For example, each support 22 includes four support blocks 221, two of which are spaced apart on one support rod 21 and the other two are spaced apart on another support rod 21.
[0076] It should be noted that in other embodiments of this utility model, the support part 22 can also be replaced by replacing the support rod 21, thereby achieving the same support for material boxes of different sizes.
[0077] For example, the bottom of the half-piece material box 201 and the full-piece material box 202 are provided with multiple spaced support grooves, and each support block 221 is inserted into the corresponding support groove. In addition, the corresponding sides of the half-piece material box 201 and the full-piece material box 202 in the width direction have multiple spaced clearance grooves. The clearance grooves can avoid the support blocks 221, so that when the material box is raised above the support rod 21, the distance that the material box needs to move in the second direction is shorter, which facilitates the quick realization of the misalignment of the support block 221 with the material box.
[0078] See also Figure 8 The battery cell transfer module 3 includes two first displacement modules 31 and two suction cups 32. The two first displacement modules 31 and the two suction cups 32 correspond one-to-one, thus enabling the transfer of half-cell batteries. This allows for the transfer of two half-cell batteries transported parallel to each other in the second direction, improving the transfer efficiency. The two first displacement modules 31 are arranged in parallel, and the two suction cups 32 are collinear in the second direction, allowing for the transfer of two half-cell batteries transported parallel to each other in the second direction.
[0079] Furthermore, the battery cell transfer module 3 also includes a lifting unit 33, a first displacement module 31 for driving the lifting unit 33 to move along a second direction, and the lifting unit 33 for driving the corresponding suction cup 32 to move up and down along a third direction.
[0080] When the transport paths of the two first displacement modules 31 happen to intersect, it will affect the equipment CT. A lifting unit 33 is set on at least one first displacement module 31, with a suction cup 32 for lifting. The two corresponding battery cells on the two suction cups 32 are misaligned in the height direction to avoid interference.
[0081] In this embodiment, there are multiple battery cell transfer modules 3 and multiple material box carrying modules 2. The multiple battery cell transfer modules 3 and multiple material box carrying modules 2 correspond one-to-one. The multiple battery cell transfer modules 3 and multiple material box carrying modules 2 are arranged sequentially along the first direction. In the first direction, the length of the two first material box conveyor belts 45 is less than the length of the multiple material box carrying modules 2. The second displacement module 41 is used to drive the lifting module 42 and the two first material box conveyor belts 45 to move along the first direction.
[0082] It is easy to understand that during the sorting of solar cells, there may be many sorting grades, requiring multiple cassettes to hold solar cells of different grades. Multiple solar cell transfer modules 3 and multiple cassette carrying modules 2 can increase the efficiency of solar cell transfer and storage. At this time, the length of the cassette carrying module 2 in the first direction is relatively large. By setting the second displacement module 41 to be able to move in the first direction (that is, the output end of the second displacement module can not only drive displacement in the first direction, but also drive displacement in the second direction), the length of the first cassette conveyor belt 45 can be reduced, avoiding the first cassette conveyor belt 45 being too heavy and thus hindering the driving of the second displacement module 41.
[0083] For example, the second displacement module 41 includes a first-direction displacement unit and a second-direction displacement unit. The output end of the first-direction displacement unit is driveably connected to the second-direction displacement unit, driving the second-direction displacement unit to move along the first direction. The output end of the second-direction displacement unit is driveably connected to the lifting module 42 and the two first material box belt conveyors 45, performing displacement drive in the second direction. Additionally, a bracket 46 is provided at the output end of the second-direction displacement unit, and the lifting module 42 and the two first material box belt conveyors 45 are all mounted on this bracket 46. The second displacement module 41 can be a gantry module.
[0084] For example, the cell conveying line 1 is arranged above the support rod 21 and below the suction cup 32, and the multiple support rods 21 can be located on the same side of the cell conveying line 1 or on both sides of the cell conveying line 1.
[0085] Figure 13 This is a schematic diagram of the arrangement of the two first material box conveyor belts provided in this embodiment of the utility model, as shown below. Figure 13 As shown, at least three workstations for supporting the material boxes are sequentially formed along the first direction on the two first material box conveyor belts 45, and the support platform 44 is arranged relative to the middle workstation.
[0086] For example, the three workstations are designated as workstation A, workstation B, and workstation C. When workstation B receives a full box, workstation A already has an empty box. At this time, the two first box conveyor belts 45 move to the right, allowing the empty box to move to workstation B, while the full box moves to workstation C. Afterward, the box transfer module 4 transports the empty box to the corresponding support 22, then transports the full box to the box conveyor line 51, receives the empty box from the conveyor line 51, and transports it to workstation A. Thus...
[0087] In this embodiment, there are two material box conveying lines 51, which are arranged sequentially along the second direction. One material box conveying line 51 is used to convey empty material boxes to two first material box belt lines 45, and the other material box conveying line 51 is used to receive full material boxes conveyed by the two first material box belt lines 45, thereby realizing the conveying of empty material boxes and full material boxes respectively.
[0088] Furthermore, the connection module 5 also includes a lifting and conveying module 52, a moving box conveyor line 53, four buffer box conveyor lines 54, and two loading and unloading box conveyor lines 55. The moving box conveyor line 53, the buffer box conveyor line 54, and the loading and unloading box conveyor line 55 all extend along a first direction. The lifting and conveying module 52 is used to drive the moving box conveyor line 53 to move along a second direction and a third direction. The moving box conveyor line 53 is used to transport boxes to other corresponding box conveyor lines or receive boxes from other corresponding box conveyor lines, realizing the transfer of empty or full boxes. Among them, two box conveyor lines 51 and one buffer box conveyor line 54 are arranged side by side and located on the lower layer, while the other three buffer box conveyor lines 54 are arranged side by side on the upper layer. The two loading and unloading box conveyor lines 55 are also arranged side by side on the upper layer. The moving box conveyor line 53 is located between the box conveyor line 51 and the loading and unloading box conveyor lines 55, the buffer box conveyor line 54, and the loading and unloading box conveyor line 55.
[0089] Specifically, when two first material box conveyor belts 45 transport full material boxes to another material box conveyor line 51, the other material box conveyor line 51 transports the full material box to a moving material box conveyor line 53. The moving material box conveyor line 53, after being moved in a second or third direction by the lifting and conveying module 52, aligns with a loading and unloading material box conveyor line 55 and transports the full material box to that loading and unloading material box conveyor line 55. The operator then removes the battery cell and transports the corresponding empty material box to another loading and unloading material box conveyor line 55. Similarly, the other loading and unloading material box conveyor line 55 transports the empty material box to a material box conveyor line 51 via the moving material box conveyor line 53, and finally to the two first material box conveyor belts 45. The four buffer material box conveyor lines 54 serve to buffer empty and full material boxes, improving the material box transfer efficiency and fault tolerance.
[0090] Additionally, each of the material box conveyor lines 51, the moving material box conveyor line 53, the four buffer material box conveyor lines 54, and the two upper and lower material box conveyor lines 55 may include two second material box belt lines 511 arranged at intervals along the second direction. Each second material box belt line 511 extends along the first direction, and the distance between the two second material box belt lines 511 is equal to that between the two first material box belt lines 45, so that half-piece material boxes 201 and full-piece material boxes 202 can be conveyed.
[0091] For example, the suction cup 32 can be a Bernoulli suction cup, the first displacement module 31 can be a linear motor module, the lifting unit 33 can be a cylinder, the lifting module 42 can be an electric cylinder, the rotation module 43 can be a rotary electric cylinder, and the lifting and conveying module 52 can be a linear motor.
[0092] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
