Abstract
Description
Technical Field
[0001] This utility model belongs to the field of solar cell production technology, specifically a vertical quartz boat used for solar cell production. Background Technology
[0002] A vertical quartz boat is a quartz product specifically designed for high-tech industries such as semiconductors and photovoltaics. It is mainly used to support substrates such as silicon wafers and crystal wafers in high-temperature processes. In the production of solar cells, vertical quartz boats are used to support silicon wafers.
[0003] When using existing quartz boats, because the silicon wafers used in solar cell production are set perpendicular to the quartz boat, the inserted silicon wafers are prone to slipping out of the boat during transfer due to the lack of a protective structure, causing damage to the silicon wafers and increasing the damage rate. Therefore, a vertical quartz boat for solar cell production is proposed to address the above problems. Utility Model Content
[0004] To overcome the shortcomings of existing technologies and address the problem that existing equipment, due to the lack of a protective structure in the quartz boat, allows inserted silicon wafers to easily slip out of the quartz boat, causing damage to the silicon wafers and increasing the damage rate, this utility model proposes a vertical quartz boat for solar cell production.
[0005] The technical solution adopted by this utility model to solve its technical problem is a vertical quartz boat for solar cell production, including a quartz boat support plate, two quartz boat support plates arranged side by side, a fixing connecting rod fixed between the two quartz boat support plates, and quartz boat feet installed at the four corners of the outer side of the quartz boat support plate.
[0006] A positioning rod is fixed between two quartz boat support plates. A swing ring is fitted on the positioning rod, a connecting rod is connected to the swing ring, and a clamping rod is fixed on the connecting rod.
[0007] The clamping rod and fixing link on the same side are provided with slots for mounting the battery cells;
[0008] Support bars are fixed on the inner sidewalls of the two quartz boat support plates, and support rods are fixed between the two support bars. An elastic lever is fixed between the outer middle of the support rod and the connecting rod. When the silicon wafer is inserted vertically, the silicon wafer is inserted along the slot in the clamping rod. At this time, the two parallel clamping rods swing outward, which realizes the pressing of the elastic lever. The elastic lever is in a bent state.
[0009] When the silicon wafer is inserted into the slot in the fixed connecting rod, it can be vertically inserted. Under the rebound effect of the elastic lever and with the cooperation of the two connecting rods, the clamping rods on both sides can clamp and limit the inserted silicon wafer, which can prevent the silicon wafer from slipping during the movement and ensure the stability of the silicon wafer transfer.
[0010] The protective rod has symmetrical sliding holes on the quartz boat support plate. The protective rod is located outside the connecting rod, and both ends of the connecting rod are slidably disposed in the sliding holes.
[0011] Preferably, the protective rod is fixed with sliders at both ends, the sliders are located on the outside of the quartz boat support plate, the bottom area of the sliders is larger than the diameter of the sliding hole, and the sliders are provided with sliding grooves.
[0012] Preferably, a linkage clamping structure is installed on the outer side of each of the two quartz boat support plates. The linkage clamping structure includes a first mounting plate and a second mounting plate. The first mounting plate and the second mounting plate are installed side by side on the outer side of the quartz boat support plate. A sliding rod is fixed between the first mounting plate and the second mounting plate. A lead screw is rotatably mounted through the first mounting plate, and the bottom end of the lead screw is rotatably mounted on one side of the second mounting plate. A damping ring is provided between the lead screw and the first mounting plate. A screw hole and a positioning hole are provided in the moving block. The lead screw rotates through the screw hole in the moving block, and the sliding rod passes through the positioning hole of the moving block.
[0013] Preferably, slide rails are fixed on both sides of the slider, and one end of the slide rail is slidably disposed in the slide groove of the slider.
[0014] Preferably, a drive shaft is installed transversely between the two quartz boat support plates, and a second bevel gear is connected to each end of the drive shaft. A first bevel gear is connected to the bottom end of the lead screw. The first bevel gear and the second bevel gear mesh with each other, and the threads of the two lead screws are in opposite directions. In order to achieve the compression and limiting of the connecting rod through the protective rod, the first bevel gear can be driven to rotate when one of the lead screws rotates. Under the transmission cooperation of the second bevel gear and the drive shaft, the lead screw in the other set can be rotated, so that the two ends of the protective rod slide synchronously, ensuring that the compression effect on the connecting rod is synchronous.
[0015] The advantages of this utility model are:
[0016] To enhance the stability of silicon wafer support, this invention inserts the silicon wafer vertically along the slots within the clamping rods. The two parallel clamping rods then swing outwards, pressing down on the elastic levers, causing them to bend. Once the silicon wafer is inserted into the slots within the fixing rods, it is placed vertically. The rebound effect of the elastic levers, combined with the clamping rods on both sides, clamps and restricts the inserted silicon wafer, preventing it from slipping during movement and ensuring the stability of the wafer transfer.
[0017] To ensure the effective clamping of the silicon wafers, the linkage clamping structure operates by sliding the protective rods on both sides towards the center. The protective rods squeeze and limit the connecting rods, ensuring the pre-tight clamping effect of the clamping rods on the silicon wafers, preventing the silicon wafers from slipping, better ensuring the transfer of the silicon wafers, reducing damage to the silicon wafers, and achieving active protection for the vertical quartz boat.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0026] Please see Figure 1-5 As shown, a vertical quartz boat for solar cell production includes a quartz boat support plate 1, two quartz boat support plates 1 arranged side by side, a fixing rod 4 fixed between the two quartz boat support plates 1, and quartz boat feet 2 installed at the four corners of the outer side of the quartz boat support plate 1.
[0027] Positioning rod 8 is fixed between two quartz boat support plates 1. A swing ring 5 is fitted on the positioning rod 8. A connecting rod 6 is connected to the swing ring 5. A clamping rod 7 is fixed on the connecting rod 6.
[0028] The clamping rod 7 and the fixing connecting rod 4 on the same side are provided with slots for mounting the battery cells.
[0029] Support bars 11 are fixed on the inner sidewalls of the two quartz boat support plates 1, and support rods 9 are fixed between the two support bars 11. An elastic lever 10 is fixed between the support rod 9 and the outer middle of the connecting rod 6. When the silicon wafer is inserted vertically, the silicon wafer is inserted along the slot in the clamping rod 7. At this time, the two parallel clamping rods 7 swing outward, which realizes the pressing of the elastic lever 10. The elastic lever 10 is in a bent state.
[0030] When the silicon wafer is inserted into the slot within the fixing link 4, it can be vertically inserted. Under the rebound effect of the elastic lever 10 and with the cooperation of the two connecting rods 6, the clamping rods 7 on both sides clamp and limit the inserted silicon wafer, which can prevent the silicon wafer from slipping during movement and ensure the stability of the silicon wafer transfer.
[0031] The protective rod 14 has symmetrical sliding holes 12 on the quartz boat support plate 1. The protective rod 14 is located outside the connecting rod 6, and the two ends of the connecting rod 6 are slidably disposed in the sliding holes 12. The protective rod 14 can limit the position of the connecting rod 6.
[0032] The protective rod 14 has sliders 13 fixed at both ends. The sliders 13 are located on the outside of the quartz boat support plate 1. The bottom area of the sliders 13 is larger than the diameter of the sliding hole 12, and a sliding groove is provided inside the sliders 13.
[0033] Two quartz boat support plates 1 are respectively equipped with a linkage clamping structure 3 on their outer sides. The linkage clamping structure 3 includes a first mounting plate 31 and a second mounting plate 36. The first mounting plate 31 and the second mounting plate 36 are mounted side by side on the outer side of the quartz boat support plate 1. A sliding rod 33 is fixedly connected between the first mounting plate 31 and the second mounting plate 36. A lead screw 37 is rotatably mounted through the first mounting plate 31, and the bottom end of the lead screw 37 is rotatably mounted on one side of the second mounting plate 36. A damping ring is provided between the lead screw 37 and the first mounting plate 31. A screw hole and a positioning hole are provided in the moving block 35. The lead screw 37 rotates through the screw hole in the moving block 35, and the sliding rod 33 passes through the positioning hole in the moving block 35. The movable block 35 has a positioning hole, and slide rails 34 are fixed on both sides. One end of the slide rail 34 is slidably set in the slide groove of the slider 13. In use, by rotating the rotating cap 32 on the outside of one of the quartz boat support plates 1, the lead screw 37 is driven to rotate, which can realize the sliding of the movable block 35 along the slide rod 33. During the upward sliding of the movable block 35, it can push the slider 13 to slide along the slide hole 12. When the two sliders 13 slide obliquely upward along the symmetrical slide holes 12, they can drive the protective rods 14 on both sides to slide towards the middle. By the compression and limiting of the connecting rod 6 by the protective rods 14, the pre-tight clamping effect of the clamping rod 7 on the silicon wafer can be guaranteed, the silicon wafer can be prevented from slipping, the transfer of the silicon wafer can be better guaranteed, and the damage of the silicon wafer can be reduced.
[0034] A drive shaft 15 is horizontally installed between the two quartz boat support plates 1, and the two ends of the drive shaft 15 are respectively connected to a second bevel gear 16. The bottom end of the lead screw 37 is connected to a first bevel gear 38. The first bevel gear 38 and the second bevel gear 16 mesh with each other, and the threads of the two lead screws 37 are opposite. In order to achieve the compression and limiting of the connecting rod 6 by means of the protective rod 14, the first bevel gear 38 can be driven to rotate when one of the lead screws 37 rotates. Under the transmission cooperation of the second bevel gear 16 and the drive shaft 15, the lead screw 37 in the other set can be rotated, so that the two ends of the protective rod 14 slide synchronously, ensuring that the compression action on the connecting rod 6 is synchronous.
[0035] Working principle: In the process of solar panel production, quartz boats are used to save space in the process.
[0036] To improve the stability of the silicon wafer, when the silicon wafer is inserted vertically, it is inserted along the slot in the clamping rod 7. At this time, the two parallel clamping rods 7 swing outward, which realizes the pressing of the elastic lever 10, and the elastic lever 10 is in a bent state.
[0037] When the silicon wafer is inserted into the slot in the fixed connecting rod 4, it can be vertically inserted. Under the rebound effect of the elastic lever 10 and with the cooperation of the two connecting rods 6, the clamping rods 7 on both sides can clamp and limit the inserted silicon wafer, which can prevent the silicon wafer from slipping during the movement and ensure the stability of the silicon wafer transfer.
[0038] To ensure the clamping effect of the silicon wafer, rotating the rotating cap 32 on the outer side of one of the quartz boat support plates 1 drives the lead screw 37 to rotate, which enables the moving block 35 to slide along the sliding rod 33. During the upward sliding of the moving block 35, it can push the slider 13 to slide along the sliding hole 12. When the two sliders 13 slide obliquely upward along the symmetrical sliding holes 12, they can drive the protective rods 14 on both sides to slide towards the middle. Through the compression and limiting of the connecting rod 6 by the protective rods 14, the pre-tight clamping effect of the clamping rod 7 on the silicon wafer can be ensured, preventing the silicon wafer from slipping, better ensuring the transfer of the silicon wafer, and reducing the damage to the silicon wafer.
[0039] When one of the lead screws 37 rotates, it drives the first bevel gear 38 to rotate. With the transmission cooperation of the second bevel gear 16 and the transmission shaft 15, the lead screw 37 in the other set can rotate, so that the two ends of the protective rod 14 can slide synchronously, ensuring that the squeezing action on the connecting rod 6 is synchronous.
