Technical Field
[0001] The invention relates to the technical field of silicon wafer production, and in particular to a double-half-wafer storage and flipping machine for solar silicon wafers. Background Art
[0002] During the printing process of solar silicon wafers on the production line, they need to be dried in the front drying furnace and printed by the rear printing machine. The drying furnace and the printing machine have different processing speeds for double half-cell silicon wafers, resulting in inconsistent processing time. According to the front and back speeds, the cache capacity should be adapted to prevent the double half-cell from staying in the drying furnace for too long, resulting in over-baking of the silicon wafers.

[0021] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.
[0022] like Figures 1 to 6 As shown, in this embodiment, a double half-cell storage and turning machine for solar silicon wafers includes a transport rail component 1, a cooling component 2, a first double half-cell buffer component 3, a second double half-cell buffer component 4 and a double half-cell flipping component 5. Two sections of half-cell conveying rails 6 are arranged on the transport rail component 1. The two sections of half-cell conveying rails 6 are placed side by side. The cooling component 2 is located on the front end side of the transport rail component 1. The upper end of the cooling component 2 is above the two sections of half-cell conveying rails 6. The middle part of the transport rail component 1 passes through the first double half-cell buffer component 3 and the second double half-cell buffer component 4 in sequence. The double half-cell flipping component 5 is located behind the second double half-cell buffer component 4.
[0023] The double-half-wafer silicon wafer coming out of the drying furnace enters the transport guide rail component 1 for transportation, first passes through the cooling component 2 for air cooling, then passes through the first double-half-wafer cache component 3 and the second double-half-wafer cache component 4 for temporary storage, and finally is flipped 180° in the double-half-wafer flip component 5 according to production requirements (if flipping is not required, it can be directly moved backward from the middle of the double-half-wafer flip component 5).
[0024] A clamping plate part 7 is provided on the transport guide rail component 1, and a clamping plate motor 8 is provided on the clamping plate part 7. The driving end of the clamping plate motor 8 is connected to a clamping plate support 11 through a synchronous wheel 9 and a synchronous belt 10. The clamping plate support 11 is located on both sides of the half-sheet conveying rail 6. A sensor 12 is installed on one side of the half-sheet conveying rail 6. The half-sheet silicon wafer is continuously conveyed backward by the belt on the half-sheet conveying rail 6 of the transport guide rail component 1. When entering the clamping plate component, the clamping plate motor 8 controls the clamping plate supports 11 on both sides to move closer to the middle of the half-sheet conveying rail 6 through the synchronous wheel 9 and the synchronous belt 10, so that the position of the half-sheet silicon wafer is placed in the middle of the half-sheet conveying rail 6, which is sensed by the sensor 12.
[0025] The cooling component 2 includes a cooling bracket 13 and a plurality of cooling fans 14. A cooling plate 15 is installed on the upper end of the cooling bracket 13. The cooling fans 14 are distributed on the cooling plate 15 along the front-to-back direction. The cooling fans 14 are located directly above the half-wafer conveying rail 6. A start button 16 is installed on the cooling plate 15. After the double half-wafer silicon wafer comes out of the high-temperature furnace, it is first located below the cooling bracket 13. After the start button 16 is started, the cooling fans 14 start working to blow air to cool the double half-wafer silicon wafer. The number of fans on both sides is the same and is distributed along the front-to-back direction.
[0026] The first double half-chip cache component 3 and the second double half-chip cache component 4 both include a cache lifting module 17 and a cache frame 18. The cache frame 18 is fixed on the driving end of the cache lifting module 17. Two groups of half-chip cache positions 19 are arranged on the cache frame 18. Cache support rods 20 are arranged on both sides of the half-chip cache positions 19. The cooled double half-chips enter the cache frame 18, and the two half-chips enter the two groups of half-chip cache positions 19 respectively. The half-chips are supported by the cache support rods 20 on both sides in each group of half-chip cache positions 19. The cache lifting module 17 controls the cache frame 18 to realize lifting and lowering, receiving and discharging half-chip silicon wafers of different layers. The front and rear first double half-chip cache component 3 and the second double half-chip cache component 4 work independently.
[0027] The double half-chip flip component 5 includes a flip side support 21, a flip motor 22 and a flip wheel 23. The flip motor 22 is fixed on the outer side of the flip side support 21. The driving end of the flip motor 22 is connected to a flip shaft 24. The flip shaft 24 passes through the middle of the flip wheel 23. The flip wheel 23 is provided with a plurality of flip grooves 25. The double half-chip silicon wafer coming out of the second double half-chip cache component 4 enters the double half-chip flip component 5. When the double half-chip silicon wafer enters the flip groove 25 under the action of the flip guide wheel, the flip motor 22 controls the rotation of the flip shaft 24 to rotate the flip wheel 23. The double half-chip silicon wafer in the flip groove 25 is flipped 180° and then output from the rear. The flipping of both sides of the double half-chip flip component 5 works independently.
[0028] An L-shaped bracket 26 is fixed to the outer side of the half-sheet conveying rail 6 , and the sensor 12 is fixed to the upper end of the L-shaped bracket 26 . The sensor 12 is aligned with the middle part of the half-sheet conveying rail 6 for sensing.
[0029] It should be stated that the above-mentioned specific implementation methods are only preferred embodiments of the present invention and the technical principles used. Within the technical scope disclosed by the present invention, any changes or substitutions that can be easily thought of by technicians familiar with this technical field should be included in the protection scope of the present invention.
