Description

Technical Field

[0001] The invention belongs to the technical field of solar cells, in particular to a flower basket structure of a single crystal silicon heterojunction solar cell slice. Background Art

[0002] Single crystal silicon heterojunction solar cell wafer is a solar cell made by forming a heterojunction between a crystalline silicon wafer and an amorphous silicon film. During the preparation process of single crystal silicon heterojunction solar cell wafer, the silicon wafer needs to be cleaned. In order to avoid the silicon wafers overlapping during the cleaning process, resulting in poor cleaning effect, the silicon wafers need to be placed in a silicon wafer basket before cleaning. The silicon wafer basket can not only provide stable support for the silicon wafers, but also separate the silicon wafers from each other, so that the cleaning liquid can evenly cover the surface of the silicon wafer to improve the cleaning efficiency.

[0003] The patent with announcement number CN109712921B discloses a flower basket structure of a monocrystalline silicon heterojunction solar cell slice, including an end plate, a first clamping tooth is welded on the front side of the inner end of the end plate, rectangular through holes are opened on the left and right ends of the outer surface of the end plate, and second clamping teeth are installed at the center positions of the left and right sides of the inner end of the end plate, and the center positions of the upper and lower ends of the second clamping teeth are screwed with fixing pins. The flower basket structure of the monocrystalline silicon heterojunction solar cell slice can reduce the lamination problem after the silicon slice is sliced ​​by installing the crude second clamping tooth at the center position of the third clamping tooth, obtain a better silicon slice surface, reduce surface recombination, increase efficiency by 0.05%, and increase EL yield by 5%. When the second rectangular plate is rotated to a horizontal position on the damping shaft, the slider can slide and adjust in the first clamping slot and the second clamping slot, which can adapt to the cleaning of silicon slices of different specifications and is more practical.

[0004] However, the above technical solution still has the following deficiencies in practical application:

[0005] Although multiple silicon wafers can be placed by means of latches and separated from each other, after cleaning, the multiple silicon wafers need to be removed manually one by one, which is rather troublesome. It not only increases the labor intensity of workers, but also affects the subsequent cleaning of silicon wafers. In addition, the multiple silicon wafers removed manually may be rather messy, which is not conducive to operations such as transportation. Manually sorting the silicon wafers also increases the labor intensity of workers.

[0006] To this end, the present invention provides a flower basket structure of a single crystal silicon heterojunction solar cell slice. Summary of the invention

[0019] The beneficial effects of the present invention are as follows:

[0020] 1. The flower basket structure of a single crystal silicon heterojunction solar cell slice of the present invention can be adapted to silicon slices of different sizes by using a motor to drive a bidirectional threaded rod to rotate according to the width of the same batch of silicon slices to be cleaned and the same specifications of the silicon slices, so that the bearing plates on both sides can slide in different directions at the same time, and the silicon slices can be inserted into the gap between the teeth, and the teeth can be used to support the silicon slices, thereby having good versatility;

[0021] 2. The flower basket structure of a single crystal silicon heterojunction solar cell slice of the present invention can drive the two supporting plates to move away from each other after a batch of silicon wafers are cleaned, so that the two sides of the silicon wafer lose the support of the teeth and fall onto the bottom plate in an overlapping state, eliminating the need for workers to manually remove multiple silicon wafers in sequence, which is more convenient and labor-saving. In addition, by using an adjustable multi-directional limiting mechanism, the silicon wafer can be supported by the first pressing plate, the second pressing plate, the pressing plate, and the frame before the two supporting plates move away from each other. When the silicon wafer loses the support of the teeth, it will move downward rapidly under the pressure of the pressing plate. Moreover, during the movement of the silicon wafer, if there is any deviation, it will be supported by the first pressing plate and the second pressing plate, so that it will not deviate and slide, and remain neat. In addition, since the pressing plate applies downward pressure on the silicon wafer, there will be no situation where a silicon wafer is lifted up and stuck between the first pressing plate and the frame, which further ensures the neatness of the silicon wafer. After multiple silicon wafers are stably stacked on the bottom plate, the first pressing plate and the second pressing plate are driven away from the silicon wafer and move upward. Then the workers can transport the stacked silicon wafers, thus avoiding the deviation and sliding of the silicon wafers due to mutual collision when they fall between the teeth, ensuring the neatness of the silicon wafers, and facilitating subsequent transportation and other operations. In addition, when the silicon wafers need to be transported in batches, before the silicon wafers fall, according to the number of silicon wafers that need to fall to the bottom plate, the mounting plate can be driven to slide up and down until the insert is aligned with the gap between the silicon wafers, and then the insert is driven to move horizontally so that the insert is inserted into the gap between the two silicon wafers. At this time, the two carrying plates are driven away from each other. When the silicon wafers fall again, they will be divided into two parts above and below the insert. The workers can transport the silicon wafers in batches, thus avoiding the situation that all the silicon wafers fall to the bottom plate at one time, which makes it difficult for the workers to transport them due to the large gravity and high stacking. At the same time, it also avoids the situation that when the silicon wafers are manually divided into two parts, the workers' hands are not easy to find the force point because the silicon wafers are close to each other, which may cause the silicon wafers to collapse.

[0044] A motor three 20 is fixedly connected to one side of the mounting plate 16 , and an output end of the motor three 20 is fixedly connected to one end of a connecting rod one 22 .

[0045] Specifically, in the existing flower basket structure of single crystal silicon heterojunction solar cell slices, although the plurality of silicon slices can be placed by the latch teeth 6 and the silicon slices are separated from each other, after cleaning, the plurality of silicon slices need to be removed manually in sequence, which is troublesome and not only increases the labor intensity of the workers, but also affects the subsequent cleaning of the silicon slices. In addition, the plurality of silicon slices removed manually may be messy, which is not conducive to operations such as transportation, and the labor intensity of the workers is also increased when the silicon slices are manually sorted.

[0046] Therefore, in order to solve the above problem, when using this embodiment, after the silicon wafer is placed between the latch teeth 6, the handle 4 is held to place the bottom plate 2 into the cleaning liquid, and the cleaning liquid just covers the top silicon wafer;

[0047] When a batch of silicon wafers are cleaned, the bottom plate 2 is taken out of the cleaning liquid and placed on the periphery, and then the motor 8 is used again to drive the bidirectional threaded rod 7 to rotate, so that the two supporting plates 5 are moved away from each other. At this time, the two sides of the silicon wafer lose the support of the latch teeth 6 and fall onto the bottom plate 2, and multiple silicon wafers overlap, thereby eliminating the process of workers manually removing multiple silicon wafers one by one, which is more convenient and labor-saving;

[0048] Since the silicon wafers may deviate or slide due to mutual collision during the falling process, thus affecting the neatness of the silicon wafers and being unfavorable for subsequent transportation and other operations, before the two carrying plates 5 move away from each other, the motor 5 25 can be used to drive the gear 26 to rotate, so that the rack rod 9 slides downward, so that the lifting plate 12 descends until the bottom of the frame 13 and the pressure plate 10 are in contact with the upper end surface of the bottom plate 2, and no matter what specifications of silicon wafers are placed on the clamping teeth 6, their rear ends are in contact with the rear ends of the carrying plates 5, and since the front end surface of the frame 13 is in contact with the rear end of the carrying plates 5, the lifting plate 12 is moved downward. Therefore, when the bottom of the frame 13 is in contact with the upper end surface of the bottom plate 2, the front end surface of the frame 13 will also be in contact with the rear end of the silicon wafer, and when the lifting plate 12 descends, the pressure plate 27 is in contact with the upper end surface of the uppermost silicon wafer, and the spring 18 is stretched. At this time, the pressure plate 27 applies a downward pressure to the silicon wafer, and then the motor 4 21 drives the threaded rod 29 to rotate, so that the adjustment plate 38 moves, so that the pressure plate 10 squeezes the front end of the silicon wafer, the spring 37 is compressed, and the pressure plate 10 applies pressure to the front end of the silicon wafer, and because the silicon wafer is placed at the latch 6, its front The end of the carrier plate 5 passes over the front end surface of the carrier plate 5, so the motor 6 35 drives the gear 2 32 to rotate, so that the rack rod 2 30 and the rack rod 3 31 on both sides can slide in different directions at the same time, so that the pressure plates 2 11 on both sides are close to each other until they fit the two sides of the silicon wafer and squeeze the silicon wafer. At this time, the two carrier plates 5 are driven away from each other. When the silicon wafer loses the support of the latch teeth 6, it will move downward rapidly under the squeezing of the pressure plate 27. Moreover, if the silicon wafer deviates during its movement, it will be resisted by the pressure plates 1 10 and 2 11 to prevent it from deviating and sliding. And keep it neat, and because the pressure plate 27 applies downward pressure to the silicon wafer, there will be no situation that a certain silicon wafer is lifted up and stuck between the pressure plate 10 and the frame 13, which further ensures the neatness of the silicon wafer. When multiple silicon wafers are stably stacked on the bottom plate 2, the pressure plate 10 and the pressure plate 2 11 are driven away from the silicon wafers and move upward, and then the workers can transport the stacked silicon wafers, thereby avoiding the silicon wafers from falling from the clamping teeth 6. The situation of offset and sliding due to mutual collision ensures the neatness of the silicon wafers, which is conducive to subsequent transportation and other operations;

[0049] In some cases, the number of silicon wafers placed between the latch teeth 6 may be large. If all the silicon wafers fall onto the bottom plate 2 at one time, it may be difficult for workers to transport them due to the large gravity and high stacking. Moreover, when the silicon wafers are manually divided into two parts for transportation, it is difficult for workers to find the force points because the silicon wafers fit together, and the silicon wafers may even collapse. Therefore, in order to avoid this problem, before the silicon wafers fall, according to the number of silicon wafers that need to fall onto the bottom plate 2, the motor 2 14 is started to drive the threaded rod 1 15 to rotate, so that the mounting plate 16 slides up and down until the insert 19 is aligned with the gap between the silicon wafers, and then the mounting plate 16 is used to move the silicon wafers. The motor three 20 drives the connecting rod one 22 and the connecting rod two 23 to rotate, so that the insert 19 can be moved horizontally and inserted into the gap between the two silicon wafers. At this time, the two supporting plates 5 are driven away from each other. When the silicon wafer falls again, it will be divided into two parts above and below the insert 19. The workers can transport the silicon wafers in batches, thereby avoiding the situation that all the silicon wafers fall onto the bottom plate 2 at one time, which makes it difficult for workers to transport them due to the large gravity and high stacking. At the same time, it also avoids the situation that when the silicon wafers are manually divided into two parts, the workers' hands are not easy to find the force point because the silicon wafers are close to each other, which may cause the silicon wafers to collapse.

[0050] Working principle: according to the width of the same batch of silicon wafers to be cleaned, and the silicon wafers have the same specifications, the motor 8 is used to drive the bidirectional threaded rod 7 to rotate, so that the supporting plates 5 on both sides can slide in different directions at the same time, and the silicon wafers are inserted into the gap of the latch teeth 6, and the latch teeth 6 are used to support the silicon wafers, so that it can adapt to silicon wafers of different sizes, with good versatility. The handle 4 is held to put the bottom plate 2 into the cleaning liquid, and the cleaning liquid just covers the top silicon wafer; when a batch of silicon wafers are cleaned, the bottom plate 2 is taken out of the cleaning liquid and placed on the periphery, and then the motor 8 is used again to drive the bidirectional threaded rod 7 to rotate, so that the two supporting plates 5 are away from each other. At this time, the two sides of the silicon wafer lose the support of the latch teeth 6 and will fall onto the bottom plate 2, and multiple silicon wafers overlap, thereby eliminating the process of workers manually removing multiple silicon wafers in sequence, which is more convenient and labor-saving;Since the silicon wafers may deviate or slide due to mutual collision during the falling process, thus affecting the neatness of the silicon wafers and being unfavorable for subsequent transportation and other operations, before the two carrying plates 5 move away from each other, the motor 5 25 can be used to drive the gear 26 to rotate, so that the rack rod 9 slides downward, so that the lifting plate 12 descends until the bottom of the frame 13 and the pressure plate 10 are in contact with the upper end surface of the bottom plate 2, and no matter what specifications of silicon wafers are placed on the clamping teeth 6, their rear ends are in contact with the rear ends of the carrying plates 5, and since the front end surface of the frame 13 is in contact with the rear end of the carrying plates 5, the lifting plate 12 is moved downward. Therefore, when the bottom of the frame 13 is in contact with the upper end surface of the bottom plate 2, the front end surface of the frame 13 will also be in contact with the rear end of the silicon wafer, and when the lifting plate 12 descends, the pressure plate 27 is in contact with the upper end surface of the uppermost silicon wafer, and the spring 18 is stretched. At this time, the pressure plate 27 applies a downward pressure to the silicon wafer, and then the motor 4 21 drives the threaded rod 29 to rotate, so that the adjustment plate 38 moves, so that the pressure plate 10 squeezes the front end of the silicon wafer, the spring 37 is compressed, and the pressure plate 10 applies pressure to the front end of the silicon wafer, and because the silicon wafer is placed at the latch 6, its front The end of the carrier plate 5 passes over the front end surface of the carrier plate 5, so the motor 6 35 drives the gear 2 32 to rotate, so that the rack rod 2 30 and the rack rod 3 31 on both sides can slide in different directions at the same time, so that the pressure plates 2 11 on both sides are close to each other until they fit the two sides of the silicon wafer and squeeze the silicon wafer. At this time, the two carrier plates 5 are driven away from each other. When the silicon wafer loses the support of the latch teeth 6, it will move downward rapidly under the squeezing of the pressure plate 27. Moreover, if the silicon wafer deviates during its movement, it will be resisted by the pressure plates 1 10 and 2 11 to prevent it from deviating and sliding. And keep it neat, and because the pressure plate 27 applies downward pressure to the silicon wafer, there will be no situation that a certain silicon wafer is lifted up and stuck between the pressure plate 10 and the frame 13, which further ensures the neatness of the silicon wafer. When multiple silicon wafers are stably stacked on the bottom plate 2, the pressure plate 10 and the pressure plate 2 11 are driven away from the silicon wafers and move upward, and then the workers can transport the stacked silicon wafers, thereby avoiding the silicon wafers from falling from the clamping teeth 6. The situation of offset and sliding due to mutual collision ensures the neatness of the silicon wafers, which is conducive to subsequent transportation and other operations;In some cases, the number of silicon wafers placed between the latch teeth 6 may be large. If all the silicon wafers fall onto the bottom plate 2 at one time, it may be difficult for workers to transport them due to the large gravity and high stacking. Moreover, when the silicon wafers are manually divided into two parts for transportation, it is difficult for workers to find the force points because the silicon wafers fit together, and the silicon wafers may even collapse. Therefore, in order to avoid this problem, before the silicon wafers fall, according to the number of silicon wafers that need to fall onto the bottom plate 2, the motor 2 14 is started to drive the threaded rod 1 15 to rotate, so that the mounting plate 16 slides up and down until the insert 19 is aligned with the gap between the silicon wafers, and then the mounting plate 16 is used to move the silicon wafers. The motor 3 20 drives the connecting rod 1 22 and the connecting rod 2 23 to rotate, so that the insert 19 can be moved horizontally and inserted into the gap between the two silicon wafers. At this time, the two carrying plates 5 are driven away from each other. When the silicon wafer falls again, it will be divided into two parts above and below the insert 19. The workers can transport the silicon wafers in batches, thereby avoiding the situation that all the silicon wafers fall on the bottom plate 2 at one time, which makes it difficult for workers to transport them due to the large gravity and high stacking. At the same time, it also avoids the situation that when the silicon wafers are manually divided into two parts, the workers' hands are not easy to find the force point because the silicon wafers are close to each other. The collapse of the silicon wafers may occur. ;
