Description

Technical Field

[0001] This utility model relates to the field of flower basket cleaning technology, specifically a photovoltaic silicon wafer flower basket cleaning device. Background Technology

[0002] Photovoltaic silicon wafers are the core basic material of solar cells. They are essentially thin sheets made of high-purity silicon (approximately 180μm ± thickness). They convert solar energy into electrical energy through the photovoltaic effect. To prevent the quality of photovoltaic silicon wafers from being affected by external contaminants during use and to extend their service life, they are usually cleaned before installation. To ensure cleaning efficiency and prevent damage to the silicon wafers during the cleaning process, photovoltaic silicon wafer baskets are typically used to hold them. These baskets are core process equipment in photovoltaic manufacturing, used for carrying, cleaning, and transporting silicon wafers. They feature a precision structure and corrosion resistance. Even after long-term use, the baskets do not deform, do not contaminate the cleaning solution, and do not scratch the silicon wafers. The hollow structure at the bottom of the basket promotes the flow of the cleaning solution and is compatible with processes such as spraying, ultrasonication, and immersion.

[0003] Traditionally, silicon wafer cleaning baskets are usually cleaned using static immersion or ultrasonic equipment. However, contaminants can easily remain in the gaps or blind spots of the basket, making it difficult to ensure the uniformity of cleaning. In addition, during the cleaning process, silicon wafer cleaning baskets often need to be manually moved and cleaned in multiple stages, which is inefficient and prone to cross-contamination.

[0004] Therefore, it is necessary to provide a new photovoltaic silicon wafer basket cleaning device to solve the above-mentioned technical problems. Utility Model Content

[0028] The working principle of the photovoltaic silicon wafer basket cleaning equipment provided by this utility model is as follows:

[0029] Before cleaning, inject a mixed solution of strong alkali and oxidant into the cleaning tank 2 located on the left, inject pure water into the cleaning tank 2 located in front, inject an acidic solution into the cleaning tank 2 located on the right, and inject high-purity water into the cleaning tank 2 located at the rear. The liquid levels of the four solutions should be just above the bottom of the four mounting tubes 5. In the initial state, the output rods of the two electric push rods 10 are both extended outwards.

[0030] Place the flower basket to be cleaned on the placement platform 24 on the left. Then, activate the two electric actuators 10. The output rods of the two electric actuators 10 gradually retract inward, driving the connecting circular plate 19 downward via the vertical rod 11. The flower basket at the top of the placement platform 24 will gradually sink into the cleaning tank 2 on the left. After the flower basket has been soaked in the mixed solution of strong alkali and oxidant for a period of time, the two electric actuators 10 are activated again. The output rods of the two electric actuators 10 gradually extend outward, exposing the flower basket from the surface of the mixed solution of strong alkali and oxidant, and the flower basket is now in the cleaning tank 2. At this time, the flower basket is located on one side of the multiple ultrasonic nozzles 6. The two electric actuators 10 are temporarily turned off. Then, the water pump 3 on the left is started. The water pump 3 generates water pressure and injects the mixed solution of strong alkali and oxidant into the installation pipe 5 through the connecting pipe 4 via the delivery pipe 7. Then, it is sprayed outward through multiple ultrasonic nozzles 6 onto the flower basket on one side. At the same time, the electric motor 22 on the left is started. The electric motor 22 drives the placement platform 24 to rotate through the rotating plate 20 and the docking plate 23. The flower basket is gradually washed by multiple ultrasonic nozzles 6 while rotating, which can wash off the oil or organic matter on the flower basket. After washing is completed, the two electric push rods 10 are started again to adjust the connecting round plate 19 and remove the flower basket from the cleaning tank 2 on the left.

[0031] Then, the electric motor 15 is started. The electric motor 15, with the help of two circular gears 18, drives the mounting block 13 to rotate counterclockwise. The mounting block 13, in turn, drives the adapter rod 9 to rotate on the circular block 8 through two connecting blocks 12. After the adapter rod 9 rotates 90 degrees, the electric motor 15 automatically shuts off. At this point, the flower basket that has undergone one round of cleaning will be moved directly above the front cleaning tank 2. Then, another flower basket that needs cleaning is placed on the left-hand placement platform 24. The previous operation is repeated, and the two electric push rods 10 are started to move the two flower baskets into the two cleaning tanks 2 respectively. The flower basket on the left undergoes preliminary cleaning, while the flower basket in front undergoes rinsing with pure water. The alkaline residue from the previous cleaning is removed, and then the two cleaning tanks 2 are rinsed with spray equipment to improve cleaning efficiency. After that, the two flower baskets are removed from the two cleaning tanks 2, and the electric motor 15 is started again to drive the two flower baskets to rotate 90 degrees counterclockwise. The position of the two flower baskets is adjusted so that they can be put into the next cleaning tank 2 for another round of cleaning. At the same time, it is convenient to put the new flower baskets into the cleaning tank 2 on the left. This process is repeated, with flower baskets being added one by one and undergoing cleaning with different solutions in the four cleaning tanks 2. After four rounds of cleaning, the flower baskets are removed from the placement platform 24 at the rear and replaced to ensure the continuous cleaning work.

[0032] Compared with related technologies, the photovoltaic silicon wafer basket cleaning equipment provided by this utility model has the following beneficial effects:

[0033] In this invention, four cleaning tanks 2 are arranged in a ring, each containing a different solution. Driven by the rotation of an electric motor 15 and the up-and-down movement of two electric push rods 10, the flower baskets can be subjected to alkaline washing, rinsing, acid washing, and final washing, forming a continuous cleaning production line. Each flower basket undergoes four rounds of soaking and cleaning. With the cooperation of four electric motors 22 and multiple ultrasonic nozzles 6, the flower baskets can be sprayed from multiple angles, achieving thorough cleaning without dead angles. Compared to static cleaning, the cleanliness is greatly improved. During the entire cleaning process, only the flower baskets need to be removed; the remaining cleaning requires no manual intervention, saving manpower and ensuring ease of operation.
