Description

Technical Field

[0001] This utility model relates to the field of battery cell manufacturing technology, and more specifically, to a flower basket. Background Technology

[0002] Currently, copper grid heterojunction solar cells require basket transport. However, due to the copper film covering, conventional EL / PL methods cannot detect microcracks in the cells within the basket. In actual production, the standard method involves manually moving the cells within the basket, taking advantage of the fact that microcracked cells are more prone to breakage than normal cells. This applies stress to the cells, and if breakage occurs at the same point, it can be identified as a microcrack.

[0003] However, manually adjusting the pressure of the pry bar to check for microcracks in the battery cells makes it difficult to control the pressure precisely, resulting in inaccurate battery cell testing results. Utility Model Content

[0004] The purpose of this invention is to provide a flower basket that can improve the accuracy of detecting microcracks in battery cells.

[0005] The embodiments of this utility model can be implemented as follows:

[0006] In a first aspect, this utility model provides a flower basket, comprising:

[0007] The flower basket body has an opening side for the battery cells to enter and exit;

[0008] The guide rail assembly is provided on the flower basket body. The guide rail assembly includes a sliding rod and rotating parts rotatably disposed at both ends of the flower basket body. The sliding rod is connected between the two rotating parts. The rotating parts are used to drive the sliding rod to rotate to be closer to or further away from the opening side.

[0009] The toggle assembly is slidably mounted on the sliding rod;

[0010] When the flower basket body is placed vertically, the actuating component slides downward along the sliding rod to abut and actuate the battery cells inside the flower basket body.

[0011] In an optional embodiment, the guide rail assembly is provided on both sides of the flower basket body, located on the opening side.

[0012] In an optional embodiment, the rotating component includes a connecting rod, one end of which is rotatably connected to the flower basket body, and the sliding rod is connected to the other end of the connecting rod.

[0013] In an optional embodiment, the actuating component includes an adjusting member and a sliding block disposed on the adjusting member. The adjusting member is slidably disposed on the sliding rod and is used to adjust the descent speed of the sliding block.

[0014] In an optional implementation, the weight of the slider is adjustable.

[0015] In an optional embodiment, the adjusting member includes a sleeve and an adjusting bolt. The sleeve is slidably fitted onto the sliding rod, and the adjusting bolt is threaded onto the sleeve along the axial direction of the sleeve to abut or move away from the sliding rod.

[0016] In an optional embodiment, the sliding rod has an abutment groove along its axial direction for accommodating the adjusting bolt.

[0017] In an optional embodiment, a guide rod is provided inside the sleeve, and a guide groove for accommodating the guide rod is formed on the sliding rod along its axial direction.

[0018] In an optional embodiment, the sliding rod is an electric optical shaft, on which the actuating component is disposed, and the electric optical shaft is used to drive the actuating component to move.

[0019] The beneficial effects of the flower basket provided in this embodiment of the utility model include:

[0020] Rotate the sliding rod to the side away from the opening of the flower basket body, load the battery cells into the flower basket body, then rotate the sliding rod back to the opening side of the flower basket body and place the flower basket body vertically. At this time, the actuating component moves downward along the sliding rod under the action of gravity. The actuating component then contacts and actuates multiple battery cells in sequence. When actuating the battery cells, the actuating force depends on the gravity of the actuating component itself, so that the force is equal when actuating each battery cell, thereby improving the detection accuracy of the battery cells.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0028] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0030] In the description of this utility model, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product is usually placed during use, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0031] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0032] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0033] In the production of solar cells, to prepare bifacial heterojunction solar cells with copper grid lines, photosensitive adhesive needs to be printed on brass sheets. The preparation process of the brass sheets is as follows: silicon wafer cleaning – texturing – heterojunction diffusion – PVD ITO plating – PVD copper film plating. After the photosensitive adhesive is printed on both sides of the brass sheet and dried, the grid line pattern is exposed. After exposure, it is sent for development to remove the adhesive from the grid lines, exposing the copper film. Then, insulating adhesive is applied to the edges, followed by electroplating, and the grid lines grow on the copper film. After the film is removed and etched back, a finished wafer is obtained. Copper grid heterojunction solar cells need to be transported using baskets. However, because of the copper film covering, conventional EL / PL cannot detect whether the cells in the basket have microcracks, chipping, or other cell degradation anomalies. Currently, in actual production, the conventional method is to take advantage of the fact that microcracked cells are more prone to breakage than normal cells. The cells are manually moved in the basket to apply force. If breakage occurs at the same point, it can be identified as a microcrack.

[0034] However, manually testing the battery cells by prying them together is difficult because it is hard to precisely control the prying force. If the prying force is too small, it will not be able to detect the battery cells with hidden cracks. If the prying force is too large, it may cause normal battery cells to break, which will lead to inaccurate testing results.

[0035] To address the aforementioned technical problems, this utility model provides a flower basket that allows for uniform force application to the battery cells within the basket, eliminating the need for manual adjustment and avoiding uneven detection results caused by manual adjustment, thus improving detection accuracy. The overall structure, working principle, and technical effects of this flower basket are described in detail below through embodiments and accompanying drawings.

[0036] Please refer to Figure 1 A flower basket includes a basket body 100, a guide rail assembly 200, and a lever assembly 300. The basket body 100 is a conventional flower basket designed to provide space for multiple battery cells, facilitating storage and transport. The basket body 100 has an opening side 110 for the battery cells to enter and exit. The battery cells enter or leave the basket body 100 through the opening side 110. The guide rail assembly 200 is mounted on the basket body 100 and includes a sliding rod 210 and rotating members 220. The rotating members 220 are mounted on the basket body 100 and located at both ends of the opening side 110. The two rotating members 220 are arranged opposite to each other, and the sliding rod 210 is connected between the two rotating members 220. The rotating members 220 can rotate relative to the basket body 100 to drive the sliding rod 210 to rotate closer to or further away from the opening side 110. The actuating component 300 is slidably mounted on the sliding rod 210. When the flower basket body 100 is placed vertically, the actuating component 300 slides down along the sliding rod 210 under the action of gravity, and the actuating component 300 is used to abut and actuate the battery inside the flower basket body 100 during the downward movement.

[0037] Rotate the sliding rod 210 to the opening side 110 away from the flower basket body 100, load the battery cells into the flower basket body 100, and then rotate the sliding rod 210 back to the opening side 110 of the flower basket body 100, placing the flower basket body 100 vertically. At this time, the actuating component 300 moves downward along the sliding rod 210 under the action of gravity. The actuating component 300 then sequentially abuts and actuates multiple battery cells. When actuating the battery cells with the actuating component 300, the actuating force depends on the weight of the actuating component 300 itself, making the force applied to each battery cell relatively uniform. By using actuating components 300 of different weights, the actuating force can be adjusted, thereby improving the accuracy of battery cell detection.

[0038] It is understandable that, since the overall height of the flower basket body 100 is limited when placed vertically, generally 30-50cm, the acceleration time and acceleration distance of the actuating component 300 during its descent under gravity are limited, and the kinetic energy will not change significantly. Therefore, the actuating component 300 exerts roughly the same force when actuating the battery cells located at the top and bottom of the flower basket body 100.

[0039] Please refer to Figure 1 and Figure 2 In some alternative embodiments, for a basket body 100 that can hold two rows of battery cells side by side, a guide rail assembly 200 is provided on both sides of the opening side 110 of the basket body 100, so that the two rows of battery cells stored in the basket body 100 can be moved and detected at the same time, thereby improving the detection efficiency.

[0040] Please refer to Figure 1 and Figure 2 In this embodiment, the rotating component 220 includes a connecting rod, which is disposed on the side of the flower basket body 100. That is, when the flower basket body 100 is placed in a vertical position, the connecting rod is provided at both the bottom and top of the flower basket body 100. One end of the connecting rod is rotatably connected to the flower basket body 100, and the other end of the connecting rod extends outside the flower basket body 100. The sliding rod 210 is connected between the ends of the two connecting rods located outside the flower basket body 100. In some alternative embodiments, the rotating component 220 may also be a strip structure such as a connecting plate or connecting piece, as long as it can drive the sliding rod 210 to rotate to the opening side 110 near or away from the flower basket body 100. The specific structural form of the connecting component is not limited here.

[0041] Please refer to Figure 3In some optional embodiments, the actuating assembly 300 includes an adjusting member 310 and a sliding block 320. The sliding block 320 is disposed on the adjusting member 310, and the adjusting member 310 is slidably mounted on the sliding rod 210. The adjusting member 310 can adjust the descent speed of the sliding block 320 on the sliding rod 210. Further, the adjusting member 310 includes a sleeve 311 and an adjusting bolt 312. The sleeve 311 is slidably sleeved on the sliding rod 210, and the adjusting bolt 312 is threaded onto the sleeve 311 along its axial direction. Thus, by turning the adjusting bolt 312, the adjusting bolt 312 is driven to contact or move away from the sliding rod 210, thereby adjusting the speed at which the sliding block 320 slides down the sliding rod 210. This allows for adjustment of the actuating force on the battery cell.

[0042] Please refer to Figure 3 and Figure 4 In some optional embodiments, to precisely adjust the pulling force of the sliding block 320 on the battery cell, an abutment groove 211 is provided on the sliding rod 210 along the axial direction of the sliding rod 210. The abutment groove 211 corresponds to and accommodates the adjusting bolt 312. When the adjusting bolt 312 is located in the abutment groove 211, the contact area between the adjusting bolt 312 and the side wall of the abutment groove 211 is adjusted by adjusting the length of the adjusting bolt 312 in the abutment groove 211, thereby adjusting the frictional resistance of the adjusting bolt 312 and thus adjusting the descent speed of the sliding block 320. At the same time, when the descent speed of the sliding block 320 remains constant, the pulling force can also be adjusted by adjusting the gravity of the sliding block 320. Different weights of sliding blocks 320 can be selected, or counterweights of different masses can be fixed on the sliding block 320 to adjust the momentum of the sliding block 320, thereby adjusting the pulling force of the sliding block 320 on the battery cell.

[0043] Please refer to Figure 3 and Figure 4 To prevent the sliding block 320 from shifting during its descent and contact with the battery cells, thus affecting the agitation effect on the battery cells, in some optional embodiments, a guide rod 313 is provided within the sleeve 311 along the radial direction of the sleeve 311, and a guide groove 212 for accommodating the guide rod 313 is formed on the sliding rod 210 along the axial direction of the sliding rod 210. Through the cooperation of the guide groove 212 and the guide rod 313, the sliding block 320 is limited during its descent, preventing it from shifting and ensuring that all the battery cells within the flower basket body 100 can be effectively agitated.

[0044] It is understood that in this embodiment, by placing the flower basket body 100 vertically, the actuating component 300 descends under gravity to actuate the battery cells. In other embodiments, the sliding rod 210 can be configured as an electric optical shaft, an electric slide, or other structures. In this case, the actuating component 300 acts as a driven device, driven by the electric optical shaft and moving along it. Simultaneously, the movement speed of the actuating component 300 can be precisely controlled. Therefore, whether the flower basket body 100 is placed horizontally or vertically, the actuating component 300 can be driven to move at a uniform speed to actuate multiple battery cells within the flower basket body 100, improving the compatibility and applicability of the flower basket.

[0045] In summary, the implementation principle of the flower basket provided by this utility model is as follows: the sliding rod 210 is rotated to the opening side 110 away from the flower basket body 100, the battery is loaded into the flower basket body 100, and then the sliding rod 210 is rotated to the opening side 110 of the flower basket body 100, and the flower basket body 100 is placed vertically. At this time, the actuating component 300 moves downward along the sliding rod 210 under the action of gravity. At this time, the actuating component 300 abuts and actuates multiple battery pieces in sequence. When the battery pieces are actuated by the actuating component 300, the actuating force depends on the gravity of the actuating component 300 itself, so that the force is equal when actuating each battery piece.

[0046] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
