[0002] In the field of solar cell manufacturing, especially considering the small size and lightweight characteristics of multi-cell solar cells, traditional transport methods mostly rely on vacuum adsorption technology for precise transport. For example, the solar cell is placed on a transport plate with multiple vacuum holes, and several independent vacuum chambers are located below the transport plate. This method allows for the transport of the solar cell. However, when transporting multi-cell solar cells, at least part of the cell loses its adsorption force when it is between two adjacent vacuum chambers, leading to jamming. Summary of the Invention

[0003] The main objective of this invention is to provide a battery cell sorting machine to solve the jamming problem caused by the use of vacuum adsorption for transporting battery cells in the prior art.

The limiting component has a limiting surface, and a limiting angle is formed between the limiting surface and the fixed space.

[0009] Furthermore, along the direction perpendicular to the fixed space, the height of the limiting surface is between 2.5mm and 3.5mm; and / or, each fixed structure is detachably connected to the transport body.

[0010] Furthermore, the limiting component includes a first limiting part and a second limiting part, the first limiting part and the second limiting part extending in different directions, wherein the side of the first limiting part that is relatively closer to the second limiting part is the first limiting surface, and the side of the second limiting part that is relatively closer to the first limiting part is the second limiting surface, and the first limiting surface and the second limiting surface together form a limiting surface.

The fixing structure also includes a first fixing member, which is provided in a one-to-one correspondence with the first fixing positions. The first fixing member can be interleaved and provided on the corresponding first fixing position so as to fix the fixed body to the transport body through the first fixing member.

[0012] Furthermore, a third fixing position is provided on the first limiting part and / or the second limiting part, and a fourth fixing position is provided on the fixing body. The third fixing position and the fourth fixing position are correspondingly provided. The limiting component also includes a limiting connector, which can be inserted into the third fixing position so as to fix the limiting component on the fixing body through the limiting connector.

[0013] Furthermore, the fixing body and the limiting component are detachably configured, or the fixing body and the limiting component are integrally formed.

[0014] Furthermore, the plurality of fixing structures include a first group of fixing structures spaced apart along a first direction and a second group of fixing structures spaced apart along a second direction, wherein the first direction is perpendicular to the second direction.

[0015] Furthermore, the cell sorting machine also includes a protective structure, which is disposed on the transport body and has a protective surface, to which at least a portion of the cell abuts.

[0016] Furthermore, the protective structure includes a plurality of first protective elements and a plurality of second protective elements, the plurality of first protective elements being arranged at intervals along a first direction and the plurality of second protective elements being arranged at intervals along a second direction, so as to form a protective surface together by the plurality of first protective elements and the plurality of second protective elements, wherein the first direction is perpendicular to the second direction.

[0017] Furthermore, each of the first protective components is disposed between two adjacent fixed structures in the first group of fixed structures; and / or, each of the second protective components is disposed between two adjacent fixed structures in the second group of fixed structures.

[0018] Furthermore, the cell sorting machine also includes an adhesive layer, which is disposed between the protective structure and the transport body to fix the protective structure to the transport body.

[0029] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] In the field of solar cell manufacturing, especially considering the small size and lightweight characteristics of multi-cell solar cells, traditional transport methods largely rely on vacuum adsorption technology for precise transport. Specifically, this technology typically involves a belt covered with perforations, beneath which multiple independent vacuum chambers are installed. When a solar cell is placed on the belt, the vacuum chambers use the suction generated by the perforations in the belt to adhere and fix the cell, thus ensuring stability during transport and reducing cell displacement.

[0031] Current traditional transmission methods exhibit inherent limitations and efficiency bottlenecks when handling the precision processing of multi-segment solar cells. Specifically, this technology relies on multiple independent vacuum chamber structures. While aiming to achieve accurate adsorption and release of solar cells through zoned control, this complex design significantly increases the initial investment cost of the equipment. During the transmission of solar cells, if the suction force distribution of the vacuum chambers is uneven, it may result in excessively strong adsorption force at one end or part of the solar cell while the other end is weak. This imbalance in suction force can easily cause tilting or jamming in the gaps of the transmission equipment. If multiple independent vacuum chambers are used to maintain the adsorption force on the transmission line, there may be a brief interruption in the adsorption force as the solar cell moves from one vacuum chamber to another. Due to the lightweight and small size of the solar cells, any slight change in adsorption force can cause them to shift position or become stuck. In addition, the belt, as the core component of the transmission system, bears the additional mechanical stress brought about by vacuum adsorption over a long period of time. This continuous high-load use accelerates the fatigue aging of the belt material, making the durability of conventional belts far lower than expected. Frequent replacement not only directly increases operating costs but also interrupts continuous production line operation, reducing production efficiency. Therefore, the purpose of this application is to provide a battery cell sorting machine, such as... Figure 1 and Figure 2 As shown, the battery cell sorting machine includes a movable transport body 2, on which multiple fixing structures 3 are provided. Each fixing structure 3 is provided with a fixing position 31. The multiple fixing positions 31 together form a fixing space. The fixing space is adapted to the size of the battery cell 1, that is, the battery cell 1 can be placed into the fixing space and will not leave the fixing space.

[0032] By setting up a transport body 2 with multiple fixed structures 3, a fixed space adapted to the shape of the battery cell 1 is formed, thereby achieving precise fixation of the battery cell 1 during transportation, avoiding offset and instability of the battery cell 1, and improving transmission accuracy and safety. This is an improvement over traditional non-fixed or imprecise fixing methods, ensuring stable transmission of the battery cell 1 in the four-piece sorting machine.

[0033] It should be noted that the cell sorting machine in this technical solution is applicable to multi-cell cells, including but not limited to two-cell cells, three-cell cells, four-cell cells, five-cell cells, etc.

[0034] Furthermore, each fixing structure 3 includes a fixing body 32 and a limiting component 33. The limiting component 33 is disposed on the side of the fixing body 32 away from the transport body 2. The limiting component 33 has a limiting surface 331, and a limiting angle is formed between the limiting surface 331 and the fixing space. At least a portion of the outer edge of the battery cell 1 contacts multiple limiting angles so that the multiple limiting angles and the fixing space cooperate to complete the fixing of the battery cell 1.

[0035] The fixing structure 3 includes a fixing body 32 and a limiting component 33. The limiting surface 331 of the limiting component 33 forms a limiting angle with the fixing space, precisely limiting the corner of the battery cell 1 and further preventing displacement of the battery cell 1 during transportation. Through the cooperation of the limiting surface and the fixing position, the positioning of the battery cell 1 is more accurate, reducing the risk of damage caused by unstable transmission and improving transmission efficiency.

[0036] Furthermore, along the direction perpendicular to the fixed space, that is, along the direction perpendicular to the fixed surface of the fixed position 31, the height of the limiting surface 331 is between 2.5mm and 3.5mm.

[0037] The height of the limiting surface 331 is set between 2.5mm and 3.5mm, ensuring that the battery cell 1 is properly raised on the fixing position 31. This provides sufficient support to prevent the battery cell 1 from sliding, while also preventing it from being too high and causing additional vibration or damage to the battery cell 1 during transportation. At the same time, the detachable design of the fixing structure 3 and the transport body 2 facilitates maintenance and adjustment, reducing the cost and time of replacing the entire structure due to damage or incompatibility.

[0038] Optionally, the height of the limiting surface 331 is any one of 2.5mm, 2.6mm, 2.7mm, 2.8mm, 2.9mm, 3.0mm, 3.1mm, 3.2mm, 3.3mm, 3.4mm, and 3.5mm.

[0039] Preferably, the height of the limiting surface 331 is 3mm.

[0040] Furthermore, the limiting component 33 includes a first limiting part 332 and a second limiting part 333. The first limiting part 332 and the second limiting part 333 extend in different directions. Specifically, the extension directions of the first limiting part 332 and the second limiting part 333 are perpendicular to each other. The side of the first limiting part 332 that is relatively closer to the second limiting part 333 is the first limiting surface 3321, and the side of the second limiting part 333 that is relatively closer to the first limiting part 332 is the second limiting surface 3331. The first limiting surface 3321 and the second limiting surface 3331 together form the limiting surface 331.

[0041] The limiting component 33 employs a first limiting part 332 and a second limiting part 333, whose different extension directions provide more comprehensive limiting protection for the corners of the battery cell 1. The combined use of the first limiting surface 3321 and the second limiting surface 3331 allows for a tighter fit against the edge of the battery cell 1, ensuring that the battery cell 1 maintains a stable position during high-speed transmission or turning, thus avoiding transmission abnormalities caused by uneven force.

[0042] Furthermore, the fixed body 32 is provided with at least two first fixing positions 321, and the transport body 2 is provided with at least two second fixing positions. Each first fixing position 321 and each second fixing position are provided in a one-to-one correspondence. The fixing structure 3 also includes a first fixing member, which is provided in a one-to-one correspondence with the first fixing positions 321. The first fixing member can be interlaced on the corresponding first fixing position 321 so as to fix the fixed body 32 to the transport body 2 through the first fixing member.

[0043] By setting a first fixing position 321 and a second fixing position, and using a first fastener to fix the fixing body 32 to the transport body 2, a stable installation of the fixing structure 3 is achieved. This design not only improves the reliability of the fixing structure 3 and reduces the risk of battery cell 1 shifting due to insecure fixing, but also facilitates the replacement and maintenance of the fixing structure 3, further reducing operating costs.

[0044] Optionally, the first fixing position 321 is a threaded hole, the second fixing position is a threaded hole, and the first fixing member is a connecting bolt.

[0045] Furthermore, a third fixing position 334 is provided on the first limiting part 332 and the second limiting part 333, and a fourth fixing position is provided on the fixing body 32. The third fixing position 334 and the fourth fixing position are correspondingly provided. The limiting component 33 also includes a limiting connector, which can be inserted into the third fixing position 334 so as to fix the limiting component 33 on the fixing body 32 through the limiting connector.

[0046] The combined use of the third fixing position 334 and the fourth fixing position, along with the application of the limiting connector, enables the limiting component 33 to be stably fixed on the fixing body 32, improving the installation accuracy and stability of the limiting component. This design ensures the continued effectiveness of the limiting component after long-term use and maintenance, reducing the impact of decreased limiting function on the transmission accuracy of the battery cell 1.

[0047] Furthermore, a third fixing position 334 is provided on the first limiting part 332 or the second limiting part 333, and a fourth fixing position is provided on the fixing body 32. The third fixing position 334 and the fourth fixing position are correspondingly provided. The limiting component 33 also includes a limiting connector, which can be inserted into the third fixing position 334 so as to fix the limiting component 33 on the fixing body 32 through the limiting connector.

[0048] The detachable design or integral molding of the fixing body 32 and the limiting component 33 allows for flexible selection of disassembly or overall replacement when adjusting the limiting accuracy or replacing damaged parts. This ensures both rapid response and maintenance efficiency while also being cost-effective. The integral molding design ensures structural stability, reduces misalignment between components, and improves the fixing effect of the limiting component on the battery cells.

[0049] Optionally, the third fixing position 334 is a threaded hole, the fourth fixing position is a threaded hole, and the limiting connector is a connecting bolt.

[0050] Furthermore, the fixed body 32 and the limiting component 33 are detachably configured.

[0051] Optionally, the fixed body 32 and the limiting component 33 are integrally formed.

[0052] The detachable design or integral molding of the fixing body 32 and the limiting component 33 allows for flexible selection of disassembly or overall replacement when adjusting the limiting accuracy or replacing damaged parts. This ensures both rapid response and maintenance efficiency of the equipment while also being cost-effective. The integral molding design ensures structural stability while reducing the matching error between various components and improving the fixing effect of the limiting component on the battery cell 1.

[0053] Furthermore, the plurality of fixing structures 3 include a first group of fixing structures 3 arranged at intervals along a first direction and a second group of fixing structures 3 arranged at intervals along a second direction, wherein the first direction is perpendicular to the second direction.

[0054] Specifically, the first set of fixed structures 3 includes two fixed structures 3, and the second set of fixed structures 3 includes two fixed structures 3.

[0055] The first and second sets of fixing structures 3 are arranged at intervals along different directions, forming a grid-like fixing system that strengthens the omnidirectional fixing capability of the solar cell 1. This design can adapt to solar cells of different sizes and shapes, improving the versatility and adaptability of the equipment, while also ensuring that the solar cell 1 receives stable and uniform support during transmission in any direction.

[0056] Furthermore, the cell sorting machine also includes a protective structure, which is disposed on the transport body 2. The protective structure has a protective surface, and at least a portion of the cell 1 abuts against the protective surface.

[0057] The protective structure, especially the protective surface on the transport body 2, provides additional safety protection for the battery cell 1. The protective surface abuts against at least a portion of the battery cell 1, reducing the chance of the battery cell 1 directly contacting the transport body 2 or other hard surfaces during transport, effectively preventing physical damage such as scratches and abrasions, and improving the integrity rate and production yield of the battery cell.

[0058] Furthermore, the protective structure includes a plurality of first protective elements and a plurality of second protective elements, the plurality of first protective elements being arranged at intervals along a first direction and the plurality of second protective elements being arranged at intervals along a second direction, so as to form a protective surface together by the plurality of first protective elements and the plurality of second protective elements, wherein the first direction is perpendicular to the second direction.

[0059] Optionally, both the first and second protective components are made of rubber.

[0060] The first and second protective components are arranged at intervals along the vertical direction, forming a protective surface that provides comprehensive protection for the solar cell 1. By setting protective components between adjacent fixing structures 3, continuous protection between fixing positions 31 is ensured, and interference between the protective structures and the fixing structures is avoided, achieving a perfect combination of fixing and protection. This design improves the safety and reliability of solar cell 1 transmission, while also reducing the complexity of equipment maintenance and ensuring the efficient operation of the solar cell 1 sorting machine.

[0061] Furthermore, each of the first protective components is disposed between two adjacent fixed structures 3 in the first group of fixed structures 3.

[0062] Furthermore, each of the second protective components is disposed between two adjacent fixed structures 3 in the second set of fixed structures 3.

[0063] The placement of the first and second protective components, i.e. the interval between the fixed structures 3, not only ensures the safety of the battery cell 1 when it moves between the fixed positions 31, but also avoids interference between the protective structure and the fixed structure 3. This achieves efficient coordination between the protection and the fixed structure 3, and improves the operational stability and maintenance convenience of the equipment.

[0064] Furthermore, the cell sorting machine also includes an adhesive layer, which is disposed between the protective structure and the transport body 2, so as to fix the protective structure to the transport body 2 through the adhesive layer.

[0065] By using an adhesive layer to fix the protective structure to the transport body 2, the installation process is simplified and the fixing strength of the protective structure is improved. The use of the adhesive layer avoids the vibration that may occur with traditional fixing methods, further protecting the battery cell 1, reducing the risks during transportation, and also facilitating the quick replacement and adjustment of the protective structure.

[0066] Furthermore, the cell sorting machine also includes a detection component, which is mounted on the transport body 2 and located in a fixed space to detect the state of the cell 1.

[0067] The detection components enable real-time monitoring of the status of solar cell 1, ensuring its correct position within a fixed space and promptly detecting and addressing any anomalies during transmission. This online detection mechanism enhances the controllability and intelligence of the transmission process, reducing equipment malfunctions and production downtime caused by abnormal solar cell conditions.

[0068] Furthermore, the detection assembly includes a detection support and a detection component, with the detection component disposed on the detection support, wherein the detection support is detachably disposed from the transport body 2.

[0069] The detachable design of the testing support and the transport body 2 ensures the installation stability of the testing components and facilitates maintenance or upgrades. This design not only improves the reliability of the testing components but also reduces maintenance costs and extends the service life of the cell sorting machine.

[0070] Optionally, the detection component is a laser detector. The detection support is a support base located below the detection component.

[0071] Furthermore, the detection support is provided with multiple first mounting positions, and the transport body is provided with multiple second mounting positions. The multiple first mounting positions and multiple second mounting positions are configured one-to-one. The detection component also includes multiple detection connectors, which are configured one-to-one with the multiple first mounting positions. The multiple detection connectors can be interleaved in their corresponding first mounting positions so as to fix the detection component on the transport body through the detection connectors.

[0072] By employing multiple corresponding first and second mounting positions and multiple detection connectors, precise fixation of the detection component is achieved. This fixation method ensures stable operation of the detection component during cell transfer, avoiding detection errors caused by loosening or misalignment of the detection component. Simultaneously, the detachable nature of the detection connectors facilitates quick replacement or adjustment of the detection component, improving the detection accuracy and efficiency of the cell sorting machine.

[0073] Optionally, the first mounting position is a threaded mounting hole, the second mounting position is a threaded mounting hole, and the testing connector is a connecting bolt.

[0074] Specifically, the transport body 2 includes a drive element and a belt. The drive element has a drive end for connecting with the belt. The drive element drives the belt to rotate so as to transport the battery cell 1 on the transport body 2.

[0075] Optionally, the battery cell sorting machine also includes a controller connected to the drive element. The controller controls the drive element to operate for a first set duration and a first set interval. Specifically, it controls the drive element to operate for the first set duration, accumulating the real-time operating time during operation. When the real-time operating time reaches the first set duration, the drive element stops moving, accumulating the real-time stopping time. When the real-time stopping time reaches the first set interval, the drive element resumes operation for the first set duration, and so on. This control method ensures that the battery cell 1 carried by the belt can be removed within the first set interval, and after removal, the belt can move promptly, allowing the battery cell 1 at the next station to be successfully removed.

[0076] Optionally, the belt conveyor has multiple stations, each station is equipped with multiple fixed structures 3, and the cell sorting machine also includes a load-bearing crossbeam 5, such as... Figure 3 As shown, an adsorption component 4 and a camera component are provided on the supporting beam 5. The adsorption component 4 can be selectively set to correspond with one of the workstations on the belt so as to remove the battery cell 1 at that workstation through the adsorption component 4. The controller is also connected to the camera component, and the camera end of the camera component is set to face the workstation below the adsorption component 4. The camera component is used to detect whether there is a battery cell 1 at the workstation corresponding to the adsorption component 4.

[0077] Optionally, when the driving element moves for a first set time, the camera detects whether there is a battery cell 1 at the workstation below the adsorption component. When the camera detects that there is a battery cell 1 at the workstation below the adsorption component 4, the controller controls the adsorption component 4 to move towards the battery cell 1, thereby using the adsorption component 4 to remove the battery cell 1 from the multiple fixed structures 3. When the camera detects that the battery cell 1 on the multiple fixed structures 3 has been removed by the adsorption component 4, the driving element stops for a first set interval. At this time, the controller continues to control the driving element to run for the first set time to move the next workstation adjacent to the current workstation to the underside of the adsorption component 4, and continues to repeat the above operation.

[0078] Alternatively, the controller can be connected to a detection component, which is used to detect whether there is a battery cell 1 at the workstation below the adsorption assembly 4.

[0079] Alternatively, the controller can be connected to both the detection component and the camera component simultaneously. In this case, the detection component and the camera component can simultaneously detect whether there is a battery cell 1 on the workstation of the belt below the adsorption assembly 4, thereby increasing the accuracy of the detection.

[0080] Specifically, the adsorption component 4 is movably mounted on the supporting crossbeam 5.

[0081] Specifically, the adsorption component 4 includes a slider 41, a steel wire rope, a drive component, a telescopic component 42, a suction cup 43, and a suction pipe 44.

[0082] Specifically, a moving track is provided on the supporting crossbeam 5, and sliders 41 are slidably connected within the moving track. Each slider 41 is connected to the others by a steel wire rope. A drive motor is connected to both the beginning and end of the steel wire rope to drive the steel wire rope to move in a first direction or a second direction, wherein the first and second directions are opposite. Controllers are connected to the drive motors located at the beginning and end of the steel wire rope. A telescopic component 42 is provided at the end of the slider 41 away from the moving track, and a suction cup 43 is provided at the telescopic end of the telescopic component 42 for suction. One end of the tube 44 is connected to the suction cup 43 to create a negative pressure inside the suction cup 43. The end of the suction tube 44 away from the suction cup 43 is connected to the suction component to remove the gas inside the suction cup 43, thereby creating a negative pressure inside the suction cup 43, which can then suck up the battery cell 1 at the work station. After the battery cell 1 at the work station is sucked up, the drive motor at the beginning of the wire rope rotates, thereby transporting the battery cell 1 to the next work station. At the same time, the previous work station continues to move to the bottom of the adsorption component, and the above movement is repeated.

[0083] Once all the battery cells 1 have been transported to the next workstation by the adsorption assembly 4, the drive motor located at the end of the wire rope can be controlled by the controller to rotate, thereby causing the wire rope to drive the slider 41 and the telescopic component 42 connected to the slider 41 to move in the second direction, thus starting the next cycle.

[0084] This technical solution achieves stability and accuracy in the transmission of battery cells 1 by introducing a driving element and an optimized belt structure. The fixing structure 3 on the belt effectively prevents the battery cells 1 from shifting during transmission, ensuring their stable positioning on the belt. The driving element rotates the belt at predetermined intervals, ensuring accurate stopping and efficient cell retrieval at each station. The connection between the controller, driving element, camera, and detection components enables precise start / stop of the driving element and dual confirmation of the battery cell 1's position, ensuring accurate cell retrieval and continuous transmission.

[0085] Furthermore, the design of the adsorption assembly 4, including the slider 41, steel wire rope, drive component, telescopic component 42, suction cup 43, and suction pipe 44, realizes the automated transfer of the battery cell 1 from the conveyor belt to the subsequent workstation. The slider 41 slides smoothly within the moving track on the supporting beam 5, and combined with the end-to-end drive of the steel wire rope, ensures the efficient movement and circulation of the adsorption assembly 4 between workstations. Through the precise control of the telescopic component 42, the suction cup 43 can accurately contact and adsorb the battery cell 1, while the connection between the suction pipe 44 and the suction component ensures the generation of negative pressure inside the suction cup 43, enabling the battery cell 1 to be stably adsorbed and transferred to the next workstation. This achieves fully automated operation from cell picking, adsorption to transfer, greatly improving production efficiency, reducing production costs, and reducing potential damage to the battery cell 1 during the transfer process, thereby improving the overall automation level of the production line and product quality.
