[0002] Silicon wafers are a crucial material for manufacturing integrated circuits. Through techniques such as photolithography and ion implantation, various semiconductor devices can be fabricated from silicon wafers. Chips made from silicon wafers possess astonishing computing power, and advancements in science and technology continuously drive the development of semiconductors. The development of technologies such as automation and computers has reduced the cost of this high-tech product, silicon wafers (integrated circuits), to an extremely low level. This has led to the widespread application of silicon wafers in aerospace, industry, agriculture, and defense, and even their quiet entry into every household.

[0003] However, after the existing photovoltaic silicon wafers are produced and processed, in order to ensure their normal processing and use in subsequent processes, workers need to manually place the processed silicon wafers into specific ultrasonic cleaning equipment for cleaning. After cleaning, workers also need to manually place them on specific racks to air dry or bake them, which is quite inconvenient. Therefore, there is a need for a photovoltaic silicon wafer cleaning device for photovoltaic panel production. By setting up cleaning frames and reciprocating lead screws and other components, workers only need to place the racks on the end face of the racks at regular intervals when using this equipment, and the silicon wafers transported by the conveyor belt can be automatically placed and cleaned, thereby improving the overall work efficiency and reducing the workload of workers.

[0020] In the following description, embodiments of the photovoltaic silicon wafer cleaning apparatus for photovoltaic panel production of this utility model will be described with reference to the accompanying drawings.

[0021] Figure 1-4This invention illustrates a photovoltaic silicon wafer cleaning device for photovoltaic panel production according to an embodiment of the present invention. It includes a support frame 1, a drive device 2 fixedly mounted at one end of the support frame 1, a fixing plate 18 fixedly mounted at one end of the support frame 1, and a water storage tank 17 fixedly mounted at one end of the fixing plate 18. A cleaning frame 20 is movably mounted inside the water storage tank 17, and a leg 21 is fixedly mounted at one end of the cleaning frame 20. The support frame 1 provides support and fixation for the fixing plate 18, ensuring that the position of the water storage tank 17 does not shift during use. The movably mounted cleaning frame 20 effectively ensures that workers can remove the cleaning frame 20 from inside the water storage tank 17. The leg 21 provides support for the cleaning frame 20, ensuring that its bottom surface contacts the end face of the water storage tank 17, ensuring that debris can settle. The cleaning frame 20 has multiple through holes 22 at one end. The water tank 17 has a limiting groove 23 inside that matches the placement bracket 16. A handle 19 is fixedly installed at one end of the cleaning frame 20. The fixing plate 18 provides support and fixation for the ultrasonic cleaning device 24, ensuring it can clean the silicon wafers inside the water tank 17. The through holes 22 allow water to pass through, preventing excess water from being carried away when the worker removes the cleaning frame 20. It also allows debris to enter the bottom of the water tank 17 through the through holes 22. The limiting groove 23... 3. To place the support bracket 16 into the cleaning frame 20, it is placed under certain restrictions to ensure that its position does not change during transportation, thus protecting the silicon wafer on the end face of the support bracket 16. A conveyor belt 4 is sleeved on the outside of the first rotating rod 3, and an extension plate 7 is fixedly installed at one end of the support frame 1. A second rotating rod 8 is movably installed inside the extension plate 7, and a belt 6 is sleeved on one end of the second rotating rod 8. The second rotating rod 8 and the first rotating rod 3 are connected by the belt 6. A placement plate 15 is fixedly installed at one end of the support frame 1, and a faucet 25 is detachably installed at one end of the support frame 1. A baffle 26 is fixedly installed at one end of the placement plate 15. The detachable faucet 25 allows workers to inject cleaning fluid into the water tank 17 through the faucet 25. A water source and a fixedly installed baffle 26 provide positioning for workers to place the placement bracket 16, ensuring easier placement. The placement bracket 16 is movably mounted on one end of the placement plate 15, and a limit plate 5 is fixedly mounted on the other end. A drive assembly for driving the placement bracket 16 is fixedly mounted on one end of the support frame 1. The drive assembly includes a first helical gear 9, a second helical gear 10, a reciprocating screw 11, a slider 12, a movable groove 13, a push rod 14, and the placement bracket 16. A slider 12 is fixedly mounted on one end of the support frame 1, and a reciprocating screw 11 is movably mounted inside the slider 12. A second helical gear 10 is fixedly mounted on one end of the reciprocating screw 11, and a first helical gear 9 meshing with the second helical gear 10 is fixedly mounted on one end of the second rotating rod 8.The direction of rotation of the reciprocating screw 11 can be changed by the transmission between the first helical gear 9 and the second helical gear 10, providing a power source for its rotation. A slider 12 is movably mounted on one end of the reciprocating screw 11, and a push rod 14 is fixedly mounted on one end of the slider 12. A movable groove 13 for the push rod 14 to move is provided at one end of the placement plate 15. The movably mounted slider 12 drives the reciprocating screw 11 to move during rotation, while the fixedly mounted push rod 14 causes the slider 12 to move along with it. The movable groove 13 provides space for the push rod 14 to move within the placement plate 15, while ensuring that it does not rotate along with the reciprocating screw 11.

[0022] Working principle: When using this utility model, simply start the drive device 2 to drive the first rotating rod 3 to rotate the conveyor belt 4. During the movement of the conveyor belt 4, the silicon wafer to be cleaned can be placed in the space inside the limiting plate 5. At the same time, while the first rotating rod 3 rotates, the second rotating rod 8 is driven by the belt 6, and then by the first helical gear 9 and the second helical gear 10, so that the reciprocating screw 11 drives the slider 12 at one end to move the push rod 14. After the worker places the placement bracket 16 on the end face of the placement plate 15, the push rod 14 will push it into place. Inside the cleaning frame 20, the silicon wafers transported by the conveyor belt 4 are picked up. The ultrasonic cleaning equipment 24 is then activated to clean the silicon wafers inside the water tank 17 and the cleaning frame 20. Workers can repeat the above operation to separate and support each photovoltaic silicon wafer, ensuring its cleaning effect. When the cleaning frame 20 is full, workers only need to pull the handle 19 to remove it from inside the water tank 17. The debris and water generated during cleaning will be discharged through the through hole 22, ensuring that the inside of the cleaning frame 20 is dry. This can effectively improve the overall work efficiency and reduce the workload of workers.

[0023] In summary, this photovoltaic silicon wafer cleaning device for photovoltaic panel production, equipped with a belt 6, a second rotating rod 8, a conveyor belt 4, and a cleaning frame 20, allows workers to operate the equipment by simply starting the drive unit 2, which drives the conveyor belt 4 to transport the photovoltaic silicon wafers placed on its end face. Simultaneously, the reciprocating screw 11 at one end of the belt 6 drives the belt. Workers simply need to position the placement bracket 16 according to the position of the push rod 14, allowing the photovoltaic silicon wafers to enter the placement bracket 16 and then into the cleaning frame 20 for ultrasonic cleaning. After cleaning, workers only need to pull the handle 19 to replace the cleaning frame 20. Compared with the traditional method of manually placing and removing silicon wafers for cleaning, this equipment eliminates the process of workers placing and removing silicon wafers, thereby improving overall work efficiency while effectively ensuring the cleaning effect on the silicon wafers.
