Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of photovoltaic cells, and particularly relates to a vertically-shaped carrier plate for cells. Background Art
[0002] At present, most of the equipment machines in the photovoltaic industry use flat carrier plates for loading and unloading. The corresponding processes for flat carrier plates are mostly carried out horizontally in the machine. However, the shapes of such equipment are huge and bloated, and the manufacturing costs are mostly relatively high. With the development of the industry, relevant manufacturers have developed vertical machines, corresponding to vertical carrier plates for processes in the machine. The vertically-shaped carrier plates carrying battery silicon wafer products are also transported and processed vertically in the machine, which has the characteristics of small floor area and low manufacturing cost, and can effectively utilize the use of factory buildings and reduce the upfront investment cost. However, the vertical carrier plates have some disadvantages compared with the flat carrier plates during use. The present invention is to improve the adverse effects brought by the vertical production process.
[0003] The vertically-shaped carrier plates first show that the battery cells are not closely attached to the carrier plates during transportation. It is easy to cause the opening and closing swing between the battery cells and the carrier plates due to bumps during transportation, and friction and bumps occur around the placement grooves of the battery cells and the carrier plates, resulting in an increase in the defective product rate such as hidden cracks, chipped edges, and broken pieces of the products, greatly affecting the yield and increasing the cost burden. Secondly, in terms of the process, since the vertically-shaped carrier plates carry battery cells, when the battery cells are in a vertical state and are subjected to bumps and the vacuum pumping and vacuum breaking actions of the gas during the process, some gaps will be generated between some battery cells and the carrier plates. During the deposition process, some gas molecular groups and atomic groups are deposited on the back of the battery cells, resulting in the problem of overplating of the battery cells. It is found in actual production that the proportion of overplating defects caused by the vertically-shaped carrier plates, whether minor or severe, almost reaches 30%. Summary of the Utility Model
[0004] In order to solve the technical problem that the battery cells on the vertically-shaped carrier plates are not closely attached to the carrier plates in the background art, the purpose of the utility model is to provide a vertically-shaped carrier plate for battery cells, which can solve the above problems.
[0005] The technical solution for achieving the purpose of the utility model is: a vertically-shaped carrier plate for battery cells, including a substrate and a placement plate. The substrate is placed vertically, and the placement plate is fixed on the substrate. The cross-section of the placement plate is wedge-shaped, and the thickness of the placement plate gradually increases from the top end of the substrate to the bottom end of the substrate.
[0006] This solution is mainly applicable to vertical deposition process machines. The cell placement area of the vertical carrier is designed with a certain inclination angle, so that when the cells are attached to the carrier, they can be more closely attached by their own gravity, thereby improving the bumps during transportation and the adverse effects caused by the pumping and breaking of vacuum of process gases, increasing the production quantity, quality and yield, and enhancing the product competitiveness. Specifically, the placement plate has a certain inclination angle, and its longitudinal section is in the shape of a triangular wedge, and after being fixed on the vertical carrier, it gradually thickens from top to bottom. In this way, after the cells are placed on the placement plate, the cells will be closely attached to the placement plate with a certain inclination angle, and there will be no problem of opening, closing and toppling with the placement plate, thus solving the problem of poor plating around the cells during the deposition process.
[0007] Furthermore, the included angle between two opposite surfaces of the placement plate with a wedge-shaped cross-section is 3° - 7°. When the angle is too small, there is still a problem of the cells opening, closing and toppling. When the angle is too large, the placement plate occupies too much space. Therefore, it is more appropriate that the included angle between two opposite surfaces of the longitudinal section of the placement plate is in the range of 3° - 7°, that is, the angle between the surface attached to the substrate and the surface where the cells are placed on the placement plate.
[0008] Furthermore, there are at least two placement plates, that is, multiple placement plates, which can place multiple cells on the substrate at the same time, improving the work efficiency; further, it can also be specified that the placement plates are arranged in an array to improve the subsequent positioning efficiency, etc.
[0009] Furthermore, a cell fixing device is also provided on the placement plate to further prevent the problem that the cells are still unstable on the placement plate during the transmission and transportation of the carrier.
[0010] Furthermore, the cell fixing device is a clamping block, and the clamping block includes a first clamping block located below the cell. Since even if the placement plate is inclined, the cells are attached to the placement plate due to their own gravity, there is still a problem that the cells slide down along the placement plate. After the first clamping block is provided below the cell, the problem of the cells sliding down can be prevented, and there will be no problem of the cells sliding down even during the vibration of the carrier during transmission and transportation.
[0011] Furthermore, second clamping blocks are provided on both sides of the cell to limit the lateral inclination or sliding of the cell and further fix the cell on the placement plate.
[0012] Furthermore, a card slot facing the cell is provided on the clamping block, and the outer edge of the cell is clamped in the card slot to improve the stability of the cell. Even if the carrier collides, the cell will not fall off due to huge jolts.
[0013] Furthermore, the card slot is arc-shaped, and the contact surface with the cell is an arc-shaped contact surface to prevent problems such as knocking and damaging the cell.
[0014] Furthermore, the size of the card slot corresponds to the thickness of the solar cell. If the card slot is too large, the solar cell will shake in the card slot; if it is too small, it will affect the clamping of the solar cell in the card slot. Therefore, it is most appropriate to match the corresponding size of the card slot according to different solar cells.
[0015] Furthermore, the placement plate can be fixed to the substrate by bolts or bonding, which is convenient for disassembly and maintenance; the clamping block can also be fixed to the placement plate by bolts or other convenient fixing connection methods, and can be freely adjusted according to different sizes of solar cells, improving the versatility of the carrier plate in this solution. The specific fixing method will not be elaborated here.
[0016] Adopting the above technical solution, the utility model has the following beneficial effects:
[0017] (1) By fixing the wedge-shaped placement plate on the substrate, the combined vertical carrier plate can well fix the solar cell, making the solar cell fit on the carrier plate;
[0018] (2) Further fix the clamping block on the placement plate to play a role in fixing the solar cell;
[0019] (3) There is a card slot on the clamping block facing the solar cell, and clamping blocks are arranged at the bottom and both sides of the solar cell. In this way, only by clamping the solar cell in the specified area can the problem of fixing the solar cell be solved, which is simple and convenient;
[0020] (4) The card slot is arc-shaped to prevent damage to the outer periphery of the solar cell. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0027] Example:
[0028] As Figure 1 - Figure 2 shown, this embodiment provides a vertically oriented carrier plate for solar cells, including a substrate 1 and a placement plate 2. The substrate 1 is vertically placed, and the placement plate 2 is fixed on the substrate 1. The cross-section of the placement plate 2 is wedge-shaped, and the thickness of the placement plate 2 gradually increases from the top end of the substrate 1 to the bottom end of the substrate 1. This solution is mainly adapted to a vertical deposition process machine. By designing a certain inclination angle for the solar cell placement area of the vertically oriented carrier plate, when the solar cell is placed on the carrier plate, it can be more closely attached by relying on its own gravity, so as to improve the bumps during transportation and the adverse effects brought by the pumping and breaking of the process gas vacuum, improve the production quality and yield, and enhance the product competitiveness. Specifically, the placement plate 2 has a certain inclination angle, and its longitudinal cross-section is triangular wedge-shaped, and after being fixed on the vertically oriented carrier plate, it gradually thickens from top to bottom. After the solar cell is placed on the placement plate 2, the solar cell will be closely attached to the placement plate 2 due to a certain inclination angle, and there will be no problem of opening, closing, or tipping over with the placement plate 2, thus solving problems such as the poor plating around the solar cell during the deposition process.
[0029] Preferably, there are at least two placement plates 2, that is, multiple placement plates, so that multiple solar cells can be placed on the substrate 1 at the same time, improving work efficiency. Further, it can be further defined that the placement plates 2 are arranged in an array to improve the subsequent positioning efficiency, etc.
[0030] Preferably, a solar cell fixing device is also provided on the placement plate 2 to further prevent the problem that the solar cell is still unstable on the placement plate 2 during the transmission and transportation of the carrier plate. The solar cell fixing device is a clamping block, and the clamping block includes a first clamping block 3 located below the solar cell. Since even if the placement plate 2 is inclined, the solar cell is attached to the placement plate 2 due to its own gravity, there is still a problem that the solar cell slides downward along the placement plate 2. After the first clamping block 3 is provided below the solar cell, the problem of the solar cell sliding downward can be prevented, and there will be no problem of the solar cell sliding downward even during the vibration of the carrier plate during transmission and transportation. Second clamping blocks 4 are provided on both sides of the solar cell to limit the lateral inclination or sliding of the solar cell, further fixing the solar cell on the placement plate 2.
[0031] As Figure 3 shown, the included angle A between two opposite faces of the placement plate with a wedge-shaped cross-section is 3° - 7°. When the angle is too small, there is still a problem of the solar cell opening, closing, or tipping over. When the angle is too large, the placement plate 2 occupies too much space. Therefore, it is more appropriate that the included angle between two opposite faces of the longitudinal cross-section of the placement plate 2 is in the range of 3° - 7°, that is, the included angle between the face attached and fixed to the substrate 1 and the face where the solar cell is placed on the placement plate 2.
[0032] As Figure 4As shown, a card slot 5 facing the solar cell is provided on the card block. The outer edge of the solar cell is clamped in the card slot 5 to improve the stability of the solar cell. Even if the carrier plate collides, the solar cell will not fall off due to huge jolts. The card slot 5 is arc-shaped, and the contact surface with the solar cell is arc-shaped to prevent problems such as knocking damage to the solar cell. The size of the card slot 5 corresponds to the thickness of the solar cell. If the card slot 5 is too large, the solar cell will shake in the card slot 5; if it is too small, it will affect the clamping of the solar cell in the card slot 5. It is most appropriate to match the card slot 5 of corresponding size according to different solar cells.
[0033] Preferably, the placement plate 2 can be fixed to the substrate 1 by bolts or bonding, which is convenient for disassembly and maintenance; the card block can also be fixed to the placement plate 2 by bolts or other convenient fixing connection methods, and can be freely adjusted according to different sizes of solar cells, improving the versatility of the carrier plate in this solution. The specific fixing method will not be elaborated here.
[0034] Working principle: When placing the solar cell on the vertical carrier plate, first install the placement plate 2 on the substrate 1, then install the first card block 3 and the second card block 4 on the placement plate 2, and then place the solar cell at the placement position 6 of the solar cell between the first card block 3 and the second card block 4. The solar cell is placed obliquely and will fit on the placement plate 2 due to its own gravity, that is, it can fit on the carrier plate.
[0035] The above specific embodiments have further elaborated the purpose, technical solution and beneficial effects of the present invention. It should be understood that the above are only specific embodiments of the present invention and do not limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
