Description

Technical fields:

[0001] This utility model belongs to the field of photovoltaic cell manufacturing technology, and specifically relates to a boat support for passivation of photovoltaic cells. Background technology:

[0002] In the manufacturing process of solar cells, the cells made of silicon wafers need to be passivated and coated on the surface of the silicon wafers to form a coating layer, which effectively reduces reflection.

[0003] To improve the coating efficiency of solar cells, the coating process typically involves placing several silicon wafers in a carrier boat, then placing the carrier boat in a support boat, and finally placing the support boat into a coating equipment for coating. This allows for the coating of multiple silicon wafers at once, thus improving production efficiency.

[0004] In actual production, the carriers are placed close together inside the carrier, resulting in poor air circulation and uneven heat distribution. This can lead to uneven heating of the solar cells within the carrier, affecting the quality of the coating. Therefore, designing a carrier with good internal air circulation is a problem that needs to be solved.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content:

[0007] To achieve the above objectives, this utility model provides a boat support for passivation of photovoltaic cells, comprising a panel, side plates, a bottom plate, partitions, airflow channels, and fixing mechanisms. The side plates are connected by the panel, forming a rectangular cavity. A bottom plate is provided at the bottom of the rectangular cavity. The panel, side plates, and bottom plate form the inner cavity of the boat support. A partition is provided in the inner cavity of the boat support, dividing the inner cavity of the boat support into several holding units. A through airflow channel is provided in the inner cavity of the boat support, passing through the center of the holding unit. The openings at both ends of the airflow channel are located on the corresponding panel. The fixing mechanisms are symmetrically arranged on both sides of the airflow channel. The airflow channel connects the holding units, and the airflow is evenly distributed in the inner cavity of the boat support. Each holding unit has two fixed positions, and each fixed position has a corresponding fixing mechanism. An auxiliary air passage is formed between the fixing mechanism and the side plate on the same side. A positioning plate is provided in the auxiliary air passage, and the two fixed positions are separated by the positioning plate.

[0008] Preferably, in the technical solution, the fixing mechanism includes fixing beams and fixing blocks. The fixing beams are symmetrically arranged on both sides of the airflow channel. The distance between the fixing beams matches the bottom structure of the carrier. Fixing blocks are evenly arranged on the fixing beams. Each fixing station is equipped with a corresponding fixing block. The structure of the fixing block matches the fixing groove at the bottom of the carrier.

[0009] Preferably, in the technical solution, the partition is a partition unit symmetrically arranged on both sides of the airflow channel. The partition unit is connected to the side plate, the bottom plate and the fixed beam respectively, and the airflow channel passes through the space between the two partition units.

[0010] Preferably, in the technical solution, the interior of the partition unit is hollowed out to facilitate air circulation between the storage units.

[0011] Preferably, in the technical solution, the positioning plate is provided with ventilation holes, and the panel is provided with ventilation openings at positions corresponding to the auxiliary air passages. The ventilation openings, ventilation holes and partition units cooperate to allow air circulation in the auxiliary air passages between the holding units.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The airflow channels and auxiliary air passages allow air to circulate between fixed workstations and between storage units, facilitating the uniform distribution of heat within the boat support cavity. This ensures that the battery cells are heated evenly during passivation, thereby improving the coating quality. Attached image description:
