[0017] The following is in conjunction with the appendix Figures 1-4 The present invention will be further described below.

[0018] In order to solve the problems existing in the background art, this application proposes the following technical solution: an aluminum boat for ALD deposition of solar cells.

[0019] The specific technical solution includes two substrates 1, multiple support rods 4, and multiple spur rods 5.

[0020] In specific implementations, such as Figure 1 As shown, two substrates 1 are arranged opposite each other. The upper part of the substrate 1 has upper mounting openings 2 at equal intervals, and the lower part of the substrate 1 has lower mounting openings 3 at equal intervals. The lower mounting openings 3 are located below the center position between two adjacent upper mounting openings 2. The two ends of the support rod 4 are respectively fixedly installed in the lower mounting openings 3 of the two substrates 1. The support rod 4 can support the bottom of the battery cell. With the help of the two side boat tooth rods 5, the battery cell can be placed relatively stably in the aluminum boat. The two ends of the boat tooth rod 5 are respectively fixedly installed in the upper mounting openings 2 of the two substrates 1. The two sides of the boat tooth rod 5 are provided with tooth grooves 6. The space between the two tooth grooves 6 of two adjacent boat tooth rods 5 is used to place the battery cell. The width of the tooth groove 6 is greater than the thickness of the battery cell. When the battery cell is placed into the tooth grooves 6 on both sides, the outer walls of the battery cell on both sides will not come into contact with the tooth grooves 6 and rub against them, preventing the edges of the battery cell from being scratched and damaged.

[0021] In specific implementations, such as Figures 2-4As shown, the top of the toothed rod 5 is equipped with a point-linkage fixing assembly 7 for fixing the battery cells. This assembly allows for simultaneous point-fixing of both sides of each battery cell, ensuring good stability during deposition. The point-linkage fixing assembly 7 includes a control plate 701 and multiple fixing plates 702 equidistantly installed on both sides of the control plate 701. A receiving groove 8 is provided at the center of the top of the toothed rod 5, extending from one end of the toothed rod 5 to the last tooth groove 6. The receiving groove 8 extends from front to back. A slot 9 communicating with the receiving groove 8 is provided on one side of the inner wall of the tooth groove 6. The slot 9 is engaged with the front inner wall of the tooth groove 6. The control plate 701 is engaged in the receiving groove 8, and the fixing plates 702 are engaged in the slot 9. The battery cells are arranged as shown... Figure 1 Place it in the aluminum boat as shown in the diagram. When placing it, you can... Figure 1 As shown, a protrusion is placed on the bottom of the front substrate 1 to tilt the aluminum boat backward. When the battery cell is placed in, it can make the battery cell contact the rear side of the toothed groove 6, pushing the control piece 701 to move along the receiving groove 8. At the same time, each fixing piece 702 on both sides of the control piece 701 can be moved out of the slot 9 and make point contact fixation to the battery cell, thereby ensuring the stable setting of the battery cell.

[0022] Furthermore, the length of the receiving slot 8 is greater than the length of the control piece 701, thus ensuring that the control piece 701 can move smoothly.

[0023] Furthermore, a positioning strip 10 is installed at the bottom of the control piece 701, and a positioning groove 11 is provided on the inner wall of the receiving groove 8. The positioning strip 10 is locked in the positioning groove 11. The cooperation between the positioning strip 10 and the positioning groove 11 can ensure the stable movement of the control piece 701.

[0024] Furthermore, the positioning strip 10 is narrower at the top and wider at the bottom, which prevents the control piece 701 from falling off the spur rod 5.

[0025] Furthermore, a mounting flap 12 is installed on the top of the substrate 1 at the end of the control piece 701. A screw hole is provided on the mounting flap 12, and a control screw 13 is engaged in the screw hole. The end of the control screw 13 is connected to the control piece 701 through a bearing 14. The position of the control piece 701 can be easily adjusted by the control screw 13.

[0026] To ensure that those skilled in the art can fully understand the technical solution, this application provides the following overall overview: In use, a protrusion is placed on the bottom of the front substrate 1 to tilt the aluminum boat backward. Then, the battery cells are placed into the toothed grooves 6 in sequence. Then, the control screw 13 is turned. Since the control screw 13 is connected to the control piece 701 through the bearing 14, when the control screw 13 is turned, the control screw 13 can push the control piece 701 to move along the receiving groove 8. At the same time, the fixing pieces 702 on both sides of the control piece 701 can be moved out from the slot 9 and make point contact fixation to the battery cells, thereby ensuring the stable setting of the battery cells.
