[0024] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0025] This utility model provides a carrier boat with a first and second slot configured as a specific groove structure. This design has at least the following advantages: First, both the first and second slots are grooves that gradually increase in size from the bottom to the opening, and the opening of the groove is relatively small. This better restricts the position of the battery cells in the device space, making it easier for several battery cells to be arranged in a uniform direction within the carrier boat. This change improves the orderly arrangement of the battery cells, thereby improving the positioning accuracy of the battery cells and addressing the problem of difficulty in improving positioning accuracy due to inconsistent battery cell orientations. During loading and unloading, battery cells can be more accurately loaded or unloaded from the carrier boat, effectively reducing the occurrence of problems such as jamming and blockage, significantly improving the accuracy of loading and unloading, and thus reducing the risk of damage such as edge chipping and microcracks that may occur during loading and unloading. At the same time, this improvement also reduces equipment failures and downtime caused by problems such as jamming and blockage, contributing to improved production efficiency. Furthermore, the precise positioning of the solar cells within the loading space reduces the likelihood of movement or displacement during transport, ensuring high transport stability and thus maintaining high positioning accuracy and improved product quality. Moreover, the relatively small contact area between the first and second slots and the solar cells minimizes potential surface contamination and damage during manufacturing. Additionally, the relatively simple processing of the first and second slots helps reduce the production cost of the carrier. Attached Figure Description

[0041] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.
[0042] Reference Figure 1-3 Firstly, this utility model provides a carrier boat 10 for battery cells.
[0043] A carrier boat 10 for battery cells includes a first side plate 11 and a second side plate 12, which are arranged in parallel with each other.
[0044] At least one first groove rod 13, one end of the first groove rod 13 is connected to the first side plate 11, and the other end is connected to the second side plate 12. A plurality of first slots 131 are distributed on the first groove rod 13.
[0045] At least one second groove rod 14, one end of which is connected to the first side plate 11 and the other end of which is connected to the second side plate 12. Several second slots 141 are distributed on the second groove rod 14. The openings of the second slots 141 and the first slots 131 are arranged facing each other to form a loading space. The loading space is configured to load the battery cell 20. Both the first slot 131 and the second slot 141 are grooves that gradually increase in size from the bottom to the opening. The included angle between the opposite sidewalls in the groove is α, where α is 11° to 14°.
[0046] Compared to related technologies, where the carrier 10 typically uses a U-shaped groove as the slot for supporting the battery cell 20, the first slot 131 and the second slot 141 of this utility model are configured with specific groove structures. This design has at least the following advantages:
[0047] First, both the first slot 131 and the second slot 141 are grooves that gradually increase in size from the bottom to the opening, with an angle α of 11° to 13°. This results in a smaller opening for the grooves, better restricting the position of the battery cells 20 within the device space, and making it easier for several battery cells 20 to be arranged in a uniform direction within the carrier boat 10. This change improves the orderly arrangement of the battery cells 20, thereby enhancing their positioning accuracy and addressing the problem of inconsistent battery cell orientations hindering accurate positioning. During loading and unloading, the battery cells 20 can be more precisely inserted into or removed from the carrier boat 10, effectively reducing issues such as chipping and blockage, significantly improving loading and unloading accuracy, and thus reducing the risk of damage such as edge chipping and microcracks that may occur during loading and unloading. Simultaneously, this improvement also reduces equipment malfunctions and downtime caused by chipping and blockage, contributing to increased production efficiency.
[0048] Furthermore, the position of the battery cell 20 in the loading space is defined, which reduces the possibility of the battery cell 20 shaking or shifting during transportation, thus maintaining high transportation stability and high positioning accuracy, and improving product quality.
[0049] Furthermore, the contact area between the first slot 131 and the second slot 141 and the battery cell 20 is relatively small, which can reduce potential contact contamination and damage to the surface of the battery cell 20 during the process.
[0050] In addition, the processing of the first slot 131 and the second slot 141 is relatively simple, which helps to reduce the production cost of the carrier boat 10.
[0051] Furthermore, continue to refer to Figure 2 and Figure 3 The first slot 131 and the second slot 141 are grooves that gradually increase in size from the bottom to the opening. When the battery cell 20 enters the groove, it engages with the opposite sidewall or bottom of the groove, thus defining the position of the battery cell 20. In this invention, the shape of the groove can be a V-shaped groove, a trapezoidal groove, or a groove that is approximately V-shaped or trapezoidal. For example, the surface of the bottom of the groove can also be an arc surface.
[0052] When the included angle between the opposite sidewalls in the groove is too large, the limiting effect of the battery cell 20 in the loading space is poor, the orderly arrangement of the battery cell 20 decreases, which is not conducive to the positioning of the battery cell 20, and makes the battery cell 20 prone to blockage and jamming during loading and unloading. When the included angle between the opposite sidewalls in the groove is too small, it is not conducive to the loading of the battery cell 20 into the carrier boat 10.
[0053] For example, α can be 11°, 11.5°, 12°, 12.3°, 12.8° or 14°, etc.
[0054] It should be noted that, in actual processing, due to factors such as precision limitations, material deformation, and measurement errors, it is often difficult for the first side plate 11 and the second side plate 12 to achieve an absolutely parallel configuration. Therefore, when this utility model mentions "parallel," it should be understood that this term not only covers the state of absolute parallelism but also includes the approximate parallelism that occurs due to reasonable deviations during actual manufacturing and installation.
[0055] Reference Figure 2 and Figure 3 In some embodiments, the spacing between adjacent first slots 131 is D1, the spacing between adjacent second slots 141 is D1, the thickness of the battery cell 20 is X1, and D1 is greater than X1.
[0056] The aforementioned setting of D1 is well-suited to the size of the solar cell 20, effectively improving the space utilization of the carrier 10 and allowing it to accommodate more solar cells 20. Therefore, the value of D1 can be determined based on the thickness design of the solar cell 20 to obtain a carrier 10 that is highly compatible with the solar cell 20.
[0057] Preferably, the spacing between adjacent first slots 131 is 2.6mm to 2.8mm, the spacing between adjacent second slots 141 is 2.6mm to 2.8mm, and the thickness of the battery cell 20 is 100μm to 180μm.
[0058] The battery cell 20 is relatively prone to deformation during loading and unloading, and the deformation increases when the size of the battery cell 20 is large. By setting the value of D1 to 2.72mm, which is significantly greater than the thickness of the battery cell 20, this design ensures that the carrier 10 of this invention is more smoothly loaded and unloaded when loading and unloading the battery cell 20, effectively reducing the risk of the battery cell 20 being stuck or scraped during loading and unloading, and thus significantly reducing the possibility of the battery cell 20 chipping and breaking. For example, the distance between adjacent first slots 131 can be 2.6mm, 2.7mm, or 2.8mm, and the distance between adjacent second slots 141 can be 2.6mm, 2.7mm, or 2.8mm, etc., and the thickness of the battery cell 20 can be 100μm, 120μm, 140μm, 160μm, or 180μm, etc.
[0059] Reference Figure 1 and Figure 4 In some embodiments, the distance between the bottom of the first slot 131 and the bottom of the second slot 141 used to form the loading space is D2, and the height of the battery cell 20 is X2, where D2 is greater than X2.
[0060] With the above settings, on the one hand, the height of the battery cell 20 is close to the bottom of the first slot 131 and the bottom of the second slot 141 that form the loading space, which can ensure the stability of the battery cell 20 in the loading space. On the other hand, it can also provide a certain error window for the battery cell 20 to enter and exit the carrier boat 10, reducing the possibility of scratches during the loading and unloading of the battery cell 20.
[0061] Furthermore, the value of D2 can be determined based on the height design of the battery cell 20 to obtain a carrier 10 with high compatibility with the battery cell 20. Preferably, the distance between the bottom of the first slot 131 and the bottom of the second slot 141 used to form the loading space is 182mm to 188mm, and the height of the battery cell 20 is 182mm to 188mm. For example, the distance between the bottom of the first slot 131 and the bottom of the second slot 141 used to form the loading space can be 182mm, 183mm, 185mm, or 188mm, and the height of the battery cell 20 can be 182mm, 183mm, 185mm, or 188mm, etc.
[0062] In some embodiments, reference is made to Figure 2 and Figure 3 The first slot 131 has a depth of S1, and the second slot 141 has a depth of S2, where S1 is greater than S2.
[0063] When the battery cell 20 is loaded onto the carrier boat 10, it can form a relatively stable engagement with the slot located below the battery cell 20 due to gravity. Whether it is easy to disengage depends mainly on the slot located above the battery cell 20. By adding S1, the first slot 131 can be used as the slot above the battery cell 20 when loading the battery cell 20, thereby reducing the probability of the battery cell 20 disengaging and effectively improving the loading stability of the battery cell 20 on the carrier boat 10.
[0064] Furthermore, S1 is 5mm to 6mm, and S2 is 4.3mm to 5.5mm.
[0065] By setting S1 and S2 within the above range, the probability of the battery cell 20 falling off can be reduced, and the loading stability of the battery cell 20 on the carrier boat 10 can be improved.
[0066] For example, S1 can be 5mm, 5.5mm or 6mm, etc., and S2 can be 4.3mm, 4.8mm or 5.5mm, etc.
[0067] Reference Figure 1 In some embodiments, there are two first groove rods 13 arranged in parallel, and two second groove rods 14 arranged in parallel, with the two first groove rods 13 and the two second groove rods 14 facing each other.
[0068] By setting two first groove rods 13 and two second groove rods 14, the number of engagement points between the battery cell 20 and the carrier boat 10 is increased, which is beneficial to improving the loading stability of the battery cell 20 in the carrier boat 10 and facilitating the transportation of the battery cell 20.
[0069] Reference Figure 4 In some embodiments, the inclination angle of the first groove rod 13 relative to the plane where the first side plate 11 is located is β, where β is 1.95° to 3°, and the inclination angle of the second groove rod 14 relative to the plane where the first side plate 11 is located is also β. It is worth noting that this inclination is based on the width direction of the first side plate 11, that is, the first groove rod 13 and the second groove rod 14 are each inclination 1.95° to 3° relative to this reference direction.
[0070] By tilting the first groove rod 13 and the second groove rod 14 relative to the first side plate 11 at the aforementioned angle, it is beneficial to guide the position of the battery cell 20 in the slot, guide the battery cell 20 to tilt in the same direction, improve the orderly arrangement of the battery cell 20 on the carrier boat 10, reduce the possibility that the battery cell 20 may tilt in different directions due to the uncertain orientation of the battery cell 20 within the loading space, thereby further improving the positioning accuracy of the battery cell 20 on the carrier boat 10, thereby reducing the difficulty of loading and unloading the battery cell 20 and reducing the probability of carding or blockage.
[0071] For example, the inclination angle of the first groove rod 13 relative to the plane where the first side plate 11 is located can be 1.95°, 1.98°, 2.0°, 2.03°, 2.5° or 3°, etc., and the inclination angle of the second groove rod 14 relative to the plane where the first side plate 11 is located can be 1.95°, 1.98°, 2.0°, 2.03°, 2.5° or 3°, etc.
[0072] Reference Figure 1 In some embodiments, the first card slot 131 and the second card slot 141 are provided in a one-to-one correspondence, and the difference between the center line of the first card slot 131 and the center line of the corresponding second card slot 141 is D3, where D3 is 6mm to 8mm.
[0073] Since the centerline of the first slot 131 differs from the centerline of the corresponding second slot 141 by 6mm to 8mm, the battery cell 20 is mounted on the carrier 10 at a certain angle and confined within the loading space, improving the orderly arrangement of the battery cell 20 and thus enhancing the positioning accuracy of the battery cell 20. For example, the difference between the centerline of the first slot 131 and the centerline of the corresponding second slot 141 can be 6mm, 7mm, or 8mm.
[0074] Secondly, this utility model provides a boat-carrying component.
[0075] Reference Figure 5A boat-carrying assembly, the boat-carrying assembly comprising:
[0076] Boat support 30;
[0077] Several boats 10, as in the first aspect, are arranged on boat support 30.
[0078] Currently used carrier boats 10 are relatively large, and during turnover, they are usually transported individually. This invention reduces the size of the carrier boat 10, thereby decreasing its deformation during transportation. Furthermore, it is used in conjunction with a boat support 30, allowing multiple carrier boats 10 to be placed within the support 30 for transport, thus improving the overall transportation efficiency of the carrier boats 10.
[0079] Reference Figure 5 In some embodiments, the boat support 30 is a long strip boat support 30, and the length direction of the boat support 30 is the first direction, that is... Figure 5 The x-direction shown;
[0080] The carrier boat 10 is a long, narrow carrier boat 10, and the length direction of the carrier boat 10 is the second direction, that is... Figure 5 As shown in the y-direction, when the boat 10 is arranged on the boat support 30, the first direction and the second direction are perpendicular to each other.
[0081] The horizontal placement of the carrier boat 10 on the boat support 30 is beneficial for improving the coating uniformity during the fabrication of Toncon solar cells (passivated contact solar cells). This is because, during the coating process of Toncon solar cells, by transferring the boat support 30 and the horizontally placed carrier boat 10 together into the coating reaction device, the horizontal placement of the carrier boat 10 helps to improve the uniformity of the coating airflow, thereby improving the coating uniformity.
[0082] Reference Figure 6 In some embodiments, the opposing surfaces of the first side plate 11 and the second side plate 12 are provided with boat ears 15, and the boat support 30 has a recessed limiting groove 31 for placing the boat ears 15. When the boat 10 is arranged on the boat support 30, the boat ears 15 are placed in the limiting groove 31. The cooperation between the boat ears 15 and the limiting groove 31 helps to improve the stability of the boat 10 on the boat support 30.
[0083] The above provides a detailed description of the carrier boat and carrier boat assembly for battery cells disclosed in the embodiments of this utility model. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The description of the above embodiments is only for the purpose of helping to understand the carrier boat and carrier boat assembly for battery cells and its core ideas. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
