[0042] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0043] In the present invention, the directions or positional relationships indicated by the terms "lower", "top", "bottom", "inner", etc. are based on the directions or positional relationships shown in the accompanying drawings. These terms are mainly used to better describe the present invention and its embodiments, and are not used to limit the indicated devices, elements or components to have a specific direction, or to be constructed and operated in a specific direction.

[0044] In addition, some of the above terms may be used to express other meanings in addition to indicating orientation or positional relationship. For example, the term "on" may also be used to express a certain dependency or connection relationship in some cases. For those skilled in the art, the specific meanings of these terms in this utility model can be understood according to specific circumstances.

[0045] In addition, the terms "disposed", "provided with", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0046] In addition, the terms "first", "second", etc. are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise specified, "plurality" means two or more.

[0047] The manufacturing process of solar cells includes multiple processes such as texturing, diffusion, SE (Selective Emitter), oxidation, and alkaline polishing, and the flow of cells between each process requires the use of a flower basket. For example, the flower basket will flow from the texturing process to the diffusion process, then to the SE process, then to the oxidation process, and finally to the alkaline polishing process before returning to the texturing process to complete a cycle. However, in this cycle, each process has different requirements for the flower basket. For example, when in the diffusion and oxidation processes, the flower basket needs to lie down and use the top teeth of the flower basket to tilt 3° to load and unload the cells. At this time, the teeth at the bottom of the flower basket are needed to support the cells so that they can be better pushed out of the flower basket. During the SE and alkaline polishing process, the flower basket needs to be upright to transfer the cells, but the cells may be dislocated during the transportation of the flower basket. In order to facilitate the transmission detection and accurate positioning of the cells, it is necessary to use a push plate to push the cells to fit the bottom rod of the flower basket so that the cells can be transferred at a unified starting position. However, the dislocated cells are only supported by the teeth on the side rods of the flower basket, and the middle part of the cells will bend downward. When pushing the cells, it is easy to hit the teeth on the bottom rod, causing damage or even breakage of the cells. It can be seen that in some processes, the teeth on the bottom rod are needed to play a fixed support role, while in some processes, the teeth on the bottom rod are not needed. This makes the flower basket incompatible with the production of multiple processes and requires frequent replacement of the flower basket, which not only affects the transportation of the cells, thereby affecting the production efficiency of solar cells, but also frequently replaces the flower basket, which may cause damage to the cells during the replacement process, affecting the product yield of solar cells.

[0048] Based on this, the utility model discloses a flower basket device, including two end plates, a plurality of first support rods, and a plurality of second support rods. The two end plates are arranged opposite to each other along the first direction, and the two ends of each first support rod are respectively connected to the two end plates, and the plurality of first support rods are arranged at intervals along the second direction. The two ends of each second support rod are respectively rotatably connected to the two end plates, and the plurality of second support rods are arranged at intervals along the second direction. Along the height direction of the end plates, the plurality of second support rods are arranged near the bottom of the end plates and are located below the first support rods to form a bearing space for carrying battery cells together with the first support rods and the end plates. The first support rod and the second support rod are respectively provided with a plurality of first latch teeth and a plurality of second latch teeth facing the bearing space, and the plurality of first latch teeth and a plurality of second latch teeth are respectively arranged at intervals along the length direction of the first support rod and the second support rod, and the first latch teeth and the second latch teeth are used to engage the battery cells in the bearing space, and the second support rod can rotate relative to the end plates along its own axial direction to change the direction of the second latch teeth.

[0049] The flower basket device in the utility model is configured such that the second support rod is rotatably connected to the two end plates. When the second support rod is rotated along its own axial direction relative to the end plates, the direction of the second latch teeth can be changed, thereby solving the problem that some processes in the manufacturing process of the battery cell require the second latch teeth on the second support rod, while some processes do not require the second latch teeth. The flower basket device is compatible with the production of multiple processes, the utilization rate of the flower basket device is improved, and the frequent replacement of the flower basket device in the middle of the process, which may damage the battery cells and affect the transportation of the battery cells, is avoided, thereby helping to improve the production efficiency and product yield of solar cells.

[0050] The technical solution of the utility model will be further described below in conjunction with embodiments and drawings.

[0051] Please also read Figure 1 to Figure 2 The utility model discloses a flower basket device 100, which includes two end plates 10, multiple first support rods 20, and multiple second support rods 30. The two end plates 10 are relatively arranged along the first direction X, and the two ends of each first support rod 20 are respectively connected to the two end plates 10, and the multiple first support rods 20 are arranged at intervals along the second direction Y. The two ends of each second support rod 30 are respectively rotatably connected to the two end plates 10, and the multiple second support rods 30 are arranged at intervals along the second direction Y. Along the height direction of the end plate 10, the multiple second support rods 30 are arranged close to the bottom of the end plate 10 and are located below the first support rods 20, so as to form a carrying space (not shown) for carrying battery cells together with the first support rods 20 and the end plate 10. Among them, the second direction Y intersects with the first direction X, and the first support rod 20 and the second support rod 30 are respectively provided with a plurality of first latch teeth 21 and a plurality of second latch teeth 311 facing the carrying space, and the plurality of first latch teeth 21 and the plurality of second latch teeth 311 are respectively arranged at intervals along the length direction of the first support rod 20 and the second support rod 30, and the first latch teeth 21 and the second latch teeth 311 are used to engage the battery cells in the carrying space, and the second support rod 30 can be rotated relative to the end plate 10 along its own axial direction to change the direction of the second latch teeth 311.

[0052] The basket device 100 disclosed in the utility model is configured such that the second support rod 30 is rotatably connected to the two end plates 10. When the second support rod 30 rotates along its own axis relative to the end plates 10, the direction of the second latching teeth 311 can be changed, so that the second latching teeth 311 can be adjusted to face the bearing space as required, and then can be adjusted according to the requirements of the second latching teeth 311 in the battery cell manufacturing process. For example, when loading and unloading cells in high-temperature processes such as diffusion and oxidation, the basket device 100 needs to lie down. At this time, the second latching teeth 311 can be made to face the bearing space to achieve positioning of the battery cell, so that the battery cell can be better taken out and prevented from being broken. When the basket device 100 needs to work upright in processes such as SE and alkaline polishing, the second support rod 30 can be rotated so that the second latching teeth 311 no longer face the bearing space, so that the battery cell can be prevented from being easily hit by the second latching teeth 311 when being pushed back after the teeth are removed, causing blockage or even battery cell breakage. Thus, the second support rod 30 is rotated to change the orientation of the second latch tooth 311, so that the basket device 100 can be compatible with the production of multiple processes, thereby improving the utilization rate of the basket device 100 and avoiding frequent replacement of the basket device 100 in the middle of the production, thereby avoiding damage to the battery cells and affecting the transportation of the battery cells, which is beneficial to improving the production efficiency and production yield of solar cells.

[0053] It should be noted that the first direction X is the length direction of the first support rod 20 and the second support rod 30, and the second direction Y is perpendicular to the first direction X. If the overall shape of the flower basket device 100 is regarded as a rectangular parallelepiped, the first direction X can be regarded as the length direction of the entire flower basket device 100, and the second direction Y is the width direction of the flower basket device 100.

[0054] It can be understood that the support rods are parallel to each other, and the plurality of first support rods 20 can be divided into two groups. The two groups of second support rods 30 are respectively arranged near the two side edges of the end plate 10, and the first support rods 20 of each group are arranged at intervals along the height direction of the end plate 10, thereby forming the side support of the flower basket device 100. The plurality of second support rods 30 are located below the first support rods 20 and are arranged on the inner side of the first support rods 20, that is, if viewed from a top angle (such as Figure 1 When observing the basket device 100, the second support rods 30 are all within the range of the first support rods 20, and all the second support rods 30 are visible and will not be blocked by the first support rods 20, thereby forming the bottom support of the basket device 100. In this way, when the second support rods 30 can effectively support the battery cells, there is no need to set too many second support rods 30. In addition, there is an opening above the bearing space formed by the first support rods 20, the second support rods 30, and the end plate 10, and the battery cells can be loaded into the bearing space through the opening.

[0055] Optionally, the number of the first support rods 20 can be six, with three rods on each side of the end plate 10, and the number of the second support rods 30 can be two. Of course, different numbers can also be set in other embodiments, such as four, six, etc., which can be adjusted according to actual needs, and the embodiments of the utility model are not specifically limited.

[0056] In addition, the material of the flower basket device 100 can be PVDF (Polyvinylidene fluoride) material, PFA (Perfluoroalkoxy, polytetrafluoroethylene) material, etc. The specific material can be selected according to the actual application scenario of the flower basket device 100, and the embodiment of the utility model does not make specific limitations.

[0057] In some embodiments, see Figure 3 to Figure 4 In order to realize the rotation of the second support rod 30, a rotation shaft 40 is provided on at least one end plate 10, and a mounting hole 321 is provided on the second support rod 30, and the rotation shaft 40 can be rotatably connected to the mounting hole 321. This way of matching the rotation shaft 40 and the mounting hole 321 utilizes part of the structure of the second support rod 30, has a simple structure, is easy to implement, and does not occupy additional space inside or outside the flower basket device 100, which is conducive to simplifying the structural design of the flower basket device 100.

[0058] It is understandable that the rotating shaft 40 and the mounting hole 321 may be provided corresponding to one of the end plates 10 , or may be provided corresponding to both end plates 10 .

[0059] In one example, the rotating shaft 40 can be independently provided, that is, when the second support rod 30 needs to be rotated, the rotating shaft 40 is inserted into the mounting hole 321 for rotation, and when it does not need to be rotated, the rotating shaft 40 is pulled out of the mounting hole 321. When the second support rod 30 needs to be rotated, the end plate 10 is fixed by the clamping device on the automation equipment, and the rotating shaft 40 is inserted into the mounting hole 321 for rotation, thereby realizing the rotation of the second support rod 30 to change the direction of the second latching tooth 311, so that the flexibility of use of the flower basket device 100 can be realized.

[0060] In another example, the rotating shaft 40 may also be connected, that is, it cannot be pulled out of the mounting hole 321 , and the second support rod 30 can also be rotated.

[0061] It is understandable that, in other embodiments, the second support rod 30 may also be directly arranged to be rotatably connected to the end plate 10, that is, the second support rod 30 itself serves as a rotating shaft, thereby eliminating the need to provide an additional rotating structure.

[0062] Furthermore, a bushing 321a is installed inside the mounting hole 321. When the rotating shaft 40 is inserted into the mounting hole 321, the bushing 321a is located between the mounting hole 321 and the rotating shaft 40. On the one hand, the wear between the rotating shaft 40 and the mounting hole 321 can be reduced, the mounting hole 321 can be prevented from being worn, and the probability of replacing the second support rod 30 can be reduced; on the other hand, a certain damping effect is provided for the rotation of the rotating shaft 40, which is more conducive to stopping after rotating to the required angle.

[0063] In practical applications, when the basket device 100 with the battery cells is in a lying position, the second support rod 30 carries more weight of the battery cells, and the second support rod 30 needs to provide a more reliable support function, so the second support rod 30 needs to have good stability and strength. Based on this, the second support rod 30 may include a rod body 31 and at least one connecting portion 32 provided on the end of the rod body 31, and the connecting portion 32 is provided with a mounting hole 321, and the mounting hole 321 extends along the length direction of the rod body 31. It can be understood that the rod body 31 is the part of the second support rod 30 located in the bearing space, and the connecting portion 32 is the part of the second support rod 30 connected to the end plate 10. The mounting hole 321 is only provided in the connecting portion 32, and does not extend to the part of the rod body 31, so that the mounting hole 321 can be prevented from extending too long to affect the connection reliability between the rotating shaft 40 and the mounting hole 321 or affect the strength of the rod body 31 of the second support rod 30, thereby affecting the stability of the second support rod 30.

[0064] It is understandable that the basket device 100 in this embodiment changes the orientation of the second latching tooth 311 by rotating the second support rod 30, but the rotation angle of the second support rod 30 is not arbitrary, and the optimal rotation angle is 90°. If the rotation angle is too small, there may still be a risk of hitting the teeth when pushing the battery cell close to the second support rod 30. If the rotation angle is too large, the second latching tooth 311 is rotated to the bottom of the basket device 100. Since each basket device 100 is stacked, the bottom second latching tooth 311 will hit the battery cell in the adjacent basket device 100, and there is also a risk of hitting the teeth. Therefore, in some implementations, a limiting structure can be set between the rotating shaft 40 and the mounting hole 321. The limiting structure realizes a rotation range of 0 to 90°, prevents the second support rod 30 from rotating at any angle, and reduces the risk of hitting the teeth of the second latching tooth 311.

[0065] In some embodiments, see Figures 5 to 7 The first latching tooth 21 includes a main body portion 211 and an extension portion 212 connected to each other along the third direction Z, and the extension portion 212 is extended toward the top of the end plate 10; the projection of the first latching tooth 21 in the second direction Y has a center point, and the distance from the center point to the projection edge of the extension portion 212 along the third direction Z (such as Figure 5L1 shown in FIG. 2 is greater than the distance from the center point to the projected edge of the main body 211 (as shown in FIG. Figure 5 L2 as shown, wherein the third direction Z is respectively perpendicular to the first direction X and the second direction Y. That is, the first latching tooth 21 is designed to be eccentric, and the eccentric direction is the side facing the opening of the bearing space. In this way, compared with the latching tooth without eccentric arrangement, the slope of the tooth surface of the extension portion 212 is gentler, and the guiding effect on the battery cell is stronger, which is more conducive to the battery cell entering the latching tooth, and the resistance between the battery cell and the tooth surface is smaller, and it is less likely to collide with the teeth and block the cell when feeding the cell, which is conducive to improving the transmission efficiency of the battery cell.

[0066] It can be understood that the third direction Z is the height direction of the flower basket device 100 , and may also be the height direction of the end plate 10 .

[0067] In some embodiments, the projection of the extension portion 212 in the second direction Y includes at least two interconnected first side edges 212a, the two first side edges 212a are connected to each other, and the angle α between one of the first side edges 212a and the center line O along the third direction Z is 20°-25°, wherein the center line O is a center line passing through the center point along the third direction Z (e.g. Figure 5 As shown in the figure, for example, the angle α can be 21°, 22°, 23°, etc. It can be understood that the center line O can be a virtual line passing through the midline point along the third direction Z. On the projection surface of the extension 212 in the second direction Y, the two first side edges 212a are connected to each other and are symmetrical with respect to the center line O, and the angle α is the angle between one of the first side edges 212a and the center line O.

[0068] By properly designing the angle α, the battery cells can be more effectively introduced into the basket device 100. If the angle is too large, the tooth surface area will be larger. In some processes that require contact with the liquid preparation, the liquid preparation will adhere to the teeth over a large area, affecting the transportation of the basket device 100. If the angle is too small, there is a greater risk of blockage, affecting the transmission efficiency of the battery cells.

[0069] In some embodiments, the projection shape of the first latch 21 in the second direction Y is a rhombus. That is, the first latch 21 is a rhombus-shaped tooth, so that the contact between the first latch 21 and the battery cell is a line contact, so that the contact area with the battery cell is as small as possible, on the one hand, it can reduce the damage to the battery cell; on the other hand, in the process where the basket device 100 needs to enter the acid and alkali solution, for example, in the texturing process, the battery cell is brought into each acid and alkali process tank for processing through the basket device 100, the smaller contact area between the first latch 21 and the battery cell can make the battery cell contact with the solution more fully, which is conducive to improving the processability of the battery cell.

[0070] In some embodiments, the projection of the first latching tooth 21 in the first direction X is a first trapezoid (eg Figure 6 ), and / or, the projection of the second latching tooth 311 in the first direction X is a second trapezoid (as shown in Figure 7 That is, the projection shape of the first latching tooth 21 and the second latching tooth 311 in the second direction Y is approximately a trapezoid, which means that the first latching tooth 21 and the second latching tooth 311 are approximately flat angles, and when the battery cell is inserted into the wrong collision tooth, it will not cause obvious scratches or chipping due to touching the sharp corners.

[0071] Optionally, the first trapezoid has a first side 21a and a second side 21b opposite to each other, the first side 21a is a side facing the top of the end plate 10, the length of the first side 21a is greater than the length of the second side 21b, and / or the second trapezoid is an isosceles trapezoid. As can be seen from the above, the first latching tooth 21 can be an eccentric rhombus tooth, so that the battery cell can be inserted into the basket device 100 more smoothly and the probability of blockage can be reduced. The second trapezoid has two opposite second side edges 311a. When the second trapezoid is an isosceles trapezoid, the two second side edges 311a are equal, that is, the second latching tooth 311 is not eccentrically designed. At this time, the second latching tooth 311 can be a rhombus tooth centrally arranged on the second support rod 30. This is because the second latching tooth 311 is a structure set as the bottom of the basket device 100 to support and constrain the battery cell, and does not participate in the process of guiding the cell into the basket. Therefore, its shape can be not specifically limited. In this way, it is sufficient to design the first latching teeth 21 to be eccentric diamond-shaped teeth, thereby simplifying the manufacturing process of the entire basket device 100 .

[0072] In addition, the first latching teeth 21 and the second latching teeth 311 are both diamond-shaped teeth, so that the first latching teeth 21 and the second latching teeth 311 can ensure that the contact area with the battery cell is as small as possible on the basis of the first latching teeth 21 and the second latching teeth 311 playing the role of segmenting and restraining the battery cell. Such a setting can save the production materials of the flower basket device 100 and reduce the material cost on the one hand, and on the other hand, the battery cell placed in the flower basket device 100 can be fully in contact with the solution during the process. Of course, it can be understood that in other embodiments, the first latching teeth 21 and the second latching teeth 311 can also be other shapes, for example, they can be fan-shaped, elliptical, etc., which can also meet the support function for the battery cell.

[0073] In some embodiments, the distance between two adjacent first latch teeth 21 may be 6 mm-7 mm, and the distance between two adjacent second latch teeth 311 may be 6 mm-7 mm, for example, 6.3 mm, 6.5 mm, 6.7 mm, etc. In this embodiment, the distance between two adjacent first latch teeth 21 is the air gap between the two adjacent first latch teeth 21 in the first direction X, that is, it can be represented by the tooth pitch of the first latch teeth 21, represented by Figure 5Accordingly, taking the second latch teeth 311 still facing the bearing space as an example, the distance between two adjacent second latch teeth 311 is the air interval between two adjacent second latch teeth 311 in the first direction X, and the tooth pitch of the second latch teeth 311 can be equal to the tooth pitch of the first latch teeth 21.

[0074] Optionally, the tooth width of the first latching tooth 21 may be 5mm-7mm, and the tooth width of the second latching tooth 311 may be 5mm-7mm, for example, 5.5mm, 6mm, 6.5mm, etc. In this embodiment, the tooth width of the first latching tooth 21 is the maximum dimension of the first latching tooth 21 in the third direction Z, which is Figure 6 Correspondingly, the tooth width of the second latching tooth 311 is the maximum dimension of the second latching tooth 311 in the second direction Y, which is Figure 7 W2 is shown in FIG.

[0075] Optionally, the tooth thickness of the first latching tooth 21 may be 3mm-5mm, and the tooth thickness of the second latching tooth 311 may be 3mm-5mm, for example, 3.5mm, 4mm, 4.5mm. In this embodiment, the tooth thickness of the first latching tooth 21 is the maximum dimension of the first latching tooth 21 in the first direction X, which is Figure 5 The tooth thickness of the second latching tooth 311 is the maximum dimension of the second latching tooth 311 in the first direction X. The tooth thickness of the second latching tooth 311 may be equal to the tooth thickness of the first latching tooth 21 .

[0076] Optionally, the tooth height of the first latching tooth 21 may be 7 mm-11 mm, and the tooth height of the second latching tooth 311 may be 7 mm-11 mm, for example, 8 mm, 9 mm, 10 mm, etc. In this embodiment, the tooth height of the first latching tooth 21 is the dimension between the part of the first latching tooth 21 farthest from the first support rod 20 and the first support rod 20 in the second direction Y, which is Figure 6 Accordingly, the tooth height of the second latching tooth 311 is the dimension between the portion of the second latching tooth 311 farthest from the second support rod 30 and the second support rod 30 in the third direction Z, which is represented by Figure 7 H2 is shown in FIG.

[0077] By reasonably configuring the various parameters of the first latch tooth 21 and the second latch tooth 311, more latch teeth can be set to separate more battery cells. While the first latch tooth 21 and the second latch tooth 311 themselves have sufficient strength, they can also be beneficial to the stability of the battery cells, so that the latch teeth can better support the battery cells.

[0078] Preferably, the distance between two adjacent first teeth 21 can be equal to the distance between two adjacent second teeth 311, both of which are 6.3 mm, the tooth width of the first tooth 21 can be equal to the tooth width of the second tooth 311, both of which are 6 mm, and the tooth thickness of the first tooth 21 can be equal to the tooth thickness of the second tooth 311, both of which are 4 mm.

[0079] After the battery cell is loaded into the basket device 100, the side edge of the battery cell is mainly supported by the first latch 21. Since both sides are supported, the stability of the side is sufficient. If the second latch 311 is required to have sufficient support, it is necessary to make further requirements on the height of the second latch 311. Based on this, in some embodiments, the tooth height of the first latch 21 is less than the tooth height of the second latch 311, so that the second latch 311 has a stronger constraint on the battery cell, which is more conducive to improving the support stability of the second latch 311.

[0080] Preferably, the tooth height of the first latching tooth 21 is 9 mm, and the tooth height of the second latching tooth 311 is 10 mm.
