Abstract
Description
Technical Field
[0001] This application belongs to the field of battery cell electroplating technology, specifically relating to a battery cell placement structure. Background Technology
[0002] In the electroplating technology of solar cell grid lines, it is necessary to conduct electricity and position the cells to ensure the accuracy of grid line electroplating. Mechanical positioning devices are usually used, such as carriers with positioning pins or positioning grooves. The cells are placed on the carrier, and the shape of the cells matches the positioning grooves to fix the cells in the correct position. At the same time, during the electroplating process, it is also necessary to continuously monitor the conductivity of the cells to avoid conductivity abnormalities.
[0003] In existing solar cell carriers, there are usually edge limiters and clamping mechanisms for holding solar cells. The edge limiters are usually designed with right angles, which makes it easy for the solar cells to be scratched and broken when they are removed. Furthermore, the clamping mechanism directly clamps the solar cells, which can cause problems such as missing grid lines at the contact point between the solar cells and the clamping mechanism, thus affecting the electroplating quality of the solar cells. Utility Model Content
[0004] This application provides a cell placement structure that can reduce the occurrence of scratches and fragments on the cells and prevent poor electroplating.
[0005] To solve the above-mentioned technical problems, this application provides a battery cell placement structure, including a cell frame, a guide groove through the cell frame, a conductive plate on the side of the cell frame near the guide groove, and a first gap for accommodating a conductive strip formed between the conductive plate and the cell frame.
[0006] A guide portion is provided on the side of the guide groove away from the conductive plate. The guide portion has a first groove along the direction away from the first gap, so as to snap the battery cell between the conductive strip and the first groove in the first direction.
[0007] As a further improvement of this application, a first side plate is connected between the conductive plate and the frame, the first side plate being hinged to the outer side wall of the conductive plate and forming the first gap between the frame and the conductive plate.
[0008] As a further improvement of this application, the conductive strip is connected to the conductive plate, and the end of the conductive strip extends out of the first gap.
[0009] As a further improvement of this application, the end of the conductive strip extends out of the first gap and connects to the battery cell that is snapped into the first groove.
[0010] As a further improvement of this application, the conductive strip is a conductive copper strip, and the number of the conductive copper strips is at least two.
[0011] As a further improvement of this application, the guide groove is adapted to the size of the battery cell, and the first groove is adapted to the thickness of the battery cell.

[0013] As a further improvement of this application, the number of guide portions is at least two, and each guide portion has a corresponding locking block on the side near the conductive plate.
[0014] As a further improvement of this application, the guide groove is provided with inclined surfaces on both sides along the first direction.
[0015] As a further improvement of this application, the two inclined surfaces gradually approach each other in the direction away from the conductive plate, so that the opening of the guide groove gradually decreases in the direction away from the conductive plate.
[0016] The battery cell placement structure provided in this application has a guide groove on the cell frame and a conductive plate on the side of the cell frame near the guide groove. A first gap is formed between the conductive plate and the cell frame to accommodate a conductive strip, allowing the conductive strip to connect to the battery cell and supply power to the battery cell, thereby monitoring the conductivity of the battery cell. A guide part is provided on the side of the guide groove away from the conductive plate, and the guide part has a first groove in the direction away from the first gap 13, thereby clamping the battery cell between the conductive strip and the first groove in the first direction, thus fixing the position of the battery cell in the first direction and preventing axial displacement of the battery cell. This eliminates the need for related structures for axial fixing of the battery cell, allowing both the front and back sides of the battery cell to have good contact with the chemical solution, avoiding poor electroplating of the battery cell, and improving the electroplating quality of the battery cell.

[0023] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.
[0024] In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified. All directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationships and movement of the components in a specific posture (as shown in the figures). If the specific posture changes, the directional indication will also change accordingly. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.
[0025] To make the description of this disclosure more detailed and complete, illustrative descriptions of the implementation methods and specific embodiments of this application are provided below; however, this is not the only form of implementing or utilizing the specific embodiments of this application. The implementation methods cover the features of multiple specific embodiments and the method steps and their order for constructing and operating these specific embodiments. However, other specific embodiments may also be used to achieve the same or equivalent functions and step sequences.
[0026] In the electroplating technology of solar cell grid lines, it is necessary to conduct electricity and position the cells to ensure the accuracy of grid line electroplating. Mechanical positioning devices are usually used, such as carriers with positioning pins or positioning grooves. The cells are placed on the carrier, and the shape of the cells matches the positioning grooves to fix the cells in the correct position. At the same time, during the electroplating process, it is also necessary to continuously monitor the conductivity of the cells to avoid conductivity abnormalities.
[0027] In existing solar cell carriers, there are usually edge limiters and clamping mechanisms for holding solar cells. The edge limiters are usually designed with right angles, which makes it easy for the solar cells to be scratched and broken when they are removed. Furthermore, the clamping mechanism directly clamps the solar cells, which can cause problems such as missing grid lines at the contact point between the solar cells and the clamping mechanism, thus affecting the electroplating quality of the solar cells.
[0028] For the reasons mentioned above, please refer to Figures 1-3 This application provides a battery cell placement structure that can reduce the occurrence of scratches and fragments on the battery cells and prevent poor electroplating of the battery cells.
[0029] Please refer to Figure 1 This is a schematic diagram of the battery cell placement structure provided in this application embodiment. The battery cell placement structure provided in this application includes a cell frame 10, on which a guide groove 11 is provided through. A conductive plate 12 is provided on the side of the cell frame 10 near the guide groove 11, so that a first gap 13 is formed between the conductive plate 12 and the cell frame 10 to accommodate the conductive strip 14, so that the conductive strip 14 is connected to the battery cell 100 to supply power to the battery cell 100, thereby monitoring the conductivity of the battery cell 100.
[0030] As an optional implementation, this application provides a guide portion 15 on the side of the guide groove 11 away from the conductive plate 12, and the guide portion 15 is provided with a first groove 16 in the direction away from the first gap 13, so that the battery cell 100 is snapped between the conductive strip 14 and the first groove 16 in the first direction.
[0031] For example, the first direction mentioned above can be understood as the vertical direction. Since the guide portion 15 has a first groove 16 in the direction away from the first gap 13, the bottom of the battery cell 100 will be engaged in the first groove 16. At the same time, the top of the battery cell 100 is connected to the conductive strip 14. Therefore, the battery cell 100 can be fixed in the vertical direction to avoid axial displacement of the battery cell 100. This eliminates the need for related structures for axial fixing of the battery cell 100, so that both the front and back of the battery cell 100 can have good contact with the liquid, thus avoiding poor electroplating of the battery cell 100.
[0032] As an optional implementation method, please refer to Figure 2 This is a side view of the battery cell placement structure provided in an embodiment of this application. In this application, a first side plate 17 is also connected between the conductive plate 12 and the cell frame 10. The first side plate 17 is hinged to the outer wall of the conductive plate 12, so that a first gap 13 is formed between the cell frame 10, the first side plate 17 and the conductive plate 12 to accommodate the conductive strip 14. The hinged arrangement also makes the position of the conductive plate 12 and the conductive strip 14 more flexible, which facilitates the replacement of the conductive strip 14 and the corresponding adjustment of the position of the conductive strip 14.
[0033] Furthermore, since the battery cell 100 is snapped onto the first groove 16 along the first direction, and the conductive strip 14 needs to be connected to the battery cell 100, this application connects the conductive strip 14 to the conductive plate 12, and sets the end of the conductive strip 14 to extend out of the first gap 13 and connect to the battery cell 100 snapped onto the first groove 16, thereby supplying power to the battery cell 100 through the conductive plate 12 and the conductive strip 14, and realizing the performance testing of the battery cell 100.
[0034] Optionally, the conductive strip 14 can be set as a conductive copper strip, and the number of conductive copper strips can be set to at least two. The specific material and number of conductive strips 14 can be adjusted according to actual needs. This application does not impose too many restrictions on this.
[0035] In this embodiment, since the battery cell 100 needs to be disposed on the guide groove 11 along the first direction, and both sides of the battery cell 100 need to be in full contact with the liquid medicine, the guide groove 11 is configured to be adapted to the size of the battery cell 100, that is, the size of the guide groove 11 is not less than the size of the battery cell 100, and the thickness of the first groove 16 is configured to be adapted to the thickness of the battery cell 100, that is, the thickness of the first groove 16 is not less than the thickness of the battery cell 100. Those skilled in the art should know this.
[0036] Preferably, the first groove 16 can be configured as a V-shaped groove structure, so as to better fix the battery cell 100 on the frame 10. The V-shaped groove mechanism can eliminate the need for the related structure of axially fixing the battery cell 100, ensuring that both the front and back of the battery cell 100 can fully contact the liquid medicine.
[0037] Furthermore, this application sets the number of guide portions 15 to at least two, and provides a corresponding locking block 151 on the side of each guide portion 15 near the conductive plate 12. The locking block 151 can be made of flexible material, and the battery piece 100 that is locked inside the first groove 16 can be reinforced by the locking block 151 to prevent the battery piece 100 from shaking in the axial direction.
[0038] In an optional embodiment, please refer to Figure 3 The above is a top view of the cross-sectional view of the battery cell placement structure provided in this application embodiment along the AA direction. It can be observed that the application provides inclined surfaces 111 on both sides of the guide groove 11 along the first direction. These two inclined surfaces 111 gradually approach each other in the direction away from the conductive plate 12, so that the opening of the guide groove 11 gradually decreases in the direction away from the conductive plate 12. In this way, when the battery cell 100 is placed near the inclined surface 111, it will not rub against the guide groove 11 due to the presence of the inclined surface 111, thus avoiding the phenomenon of the battery cell 100 breaking.
[0039] The battery cell placement structure provided in this application has a guide groove on the cell frame and a conductive plate on the side of the cell frame near the guide groove. A first gap is formed between the conductive plate and the cell frame to accommodate a conductive strip, allowing the conductive strip to connect to the battery cell and supply power to the battery cell, thereby monitoring the conductivity of the battery cell. A guide part is provided on the side of the guide groove away from the conductive plate, and the guide part has a first groove in the direction away from the first gap 13, thereby clamping the battery cell between the conductive strip and the first groove in the first direction, thus fixing the position of the battery cell in the first direction and preventing axial displacement of the battery cell. This eliminates the need for related structures for axial fixing of the battery cell, allowing both the front and back sides of the battery cell to have good contact with the chemical solution, avoiding poor electroplating of the battery cell, and improving the electroplating quality of the battery cell.
[0040] It is understood that the technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0041] The above embodiments are merely exemplary implementations used to illustrate the principles of this application; however, this application is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and substance of this application, and these modifications and improvements are also considered to be within the scope of protection of this application.
