Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, in particular to a single crystal edge skin end face cleaning machine. Background Art

[0002] Single crystal edge skin refers to a part of the single crystal silicon material removed when a single crystal round rod is squared into a single crystal square rod. This part of the material can be used as a recycled material. After the single crystal edge skin is cut from the entire crystal rod, metal particles and stains such as cutting fluid remain on the surface. These substances will affect the minority carrier lifetime of the crystal rod and reduce the quality of the edge skin recycled material. It is usually necessary to undergo a cleaning process to remove the metal impurity particles on the edge skin material. The cleaning machine in the prior art needs to perform complex operations and fix the single crystal edge skin, resulting in the end face not being cleaned, which will waste a considerable amount of time, and the end face of the edge skin cannot be effectively cleaned. The residual metal particles make the work efficiency low. In addition, the cleaning machine adopts a flushing structure, and the cleaning effect is poor. Utility Model Content

[0019] Now, the present utility model will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model

[0020] As shown in Figure 1 is a schematic diagram of the structure of the present utility model. A single-crystal edge and end face cleaning machine includes a housing 1, a cleaning mechanism 2 and a fixing mechanism 3. A cleaning chamber 11 is formed by opening on the housing 1. The cleaning chamber 11 has a through structure at both ends. The cleaning mechanism 2 and the fixing mechanism 3 are located in the cleaning chamber 11, and both the cleaning mechanism 2 and the fixing mechanism 3 are installed on the housing 1. The cleaning mechanism 2 is located above the fixing mechanism 3

[0021] As shown in Figure 2 、 Figure 3 shown, the cleaning mechanism 2 is used to clean the single-crystal edge. The cleaning mechanism 2 includes a plurality of cleaning rollers 21. The cleaning rollers 21 are rotatably connected to the housing 1. The cleaning rollers 21 gradually decrease from the input end to the output end of the cleaning chamber 11. The cleaning mechanism 2 includes an adjusting member 22 and a mounting seat 23. The mounting seats 23 correspond to the side ends of the cleaning rollers 21 one by one. The side ends of the cleaning rollers 21 are rotatably connected to the corresponding mounting seats 23. An adjusting chamber 12 is opened on the housing 1. The mounting seats 23 are slidably arranged in the adjusting chamber 12. The adjusting member 22 is fixedly connected to the housing 1, and the adjusting member 22 is located in the adjusting chamber 12. The output end of the adjusting member 22 is in transmission connection with the mounting seat 23. The adjusting member 22 is used to provide power for the rising or falling of the cleaning rollers 21. The adjusting member 22 is a power element such as a hydraulic cylinder or a cylinder. The cleaning mechanism 2 further includes a motor. The motor is fixedly connected to the housing 1. The output shaft of the motor is in transmission connection with the cleaning rollers 21. The motor can provide power for the rotation of the cleaning rollers 21. Cleaning brushes are attached to the surfaces of the cleaning rollers 21. Through the design of the cleaning rollers 21 with gradually decreasing height, on the one hand, the single-crystal edge can be gradually cleaned with good cleaning effect, and on the other hand, it is convenient for the single-crystal edge to contact the cleaning rollers 21, avoiding excessive extrusion of the single-crystal edge when the cleaning rollers approach the single-crystal edge

[0022] As shown in Figure 1 、 Figure 2As shown, the fixing mechanism 3 is used for mounting the single-crystal edge skin and providing power for its movement. The fixing mechanism 3 includes a fixing base 31, which is slidably connected to the housing 1. A fixing groove 311 for accommodating the single-crystal edge skin is formed on one side of the fixing base 31 close to the cleaning roller 21.

[0023] The fixing mechanism 3 includes a slide rail 32 and a slider 33 that matches the slide rail 32. The slide rail 32 is fixedly connected to the housing 1, the slider 33 is fixedly connected to the fixing base 31, the slider 33 is slidably connected to the slide rail 32, and a power mechanism is installed inside the slider 33. The power mechanism includes a roller and a motor. The roller contacts the slide rail 32, and the output shaft of the motor is drivingly connected to the roller. The power mechanism 32 provides power for the active movement of the slider 33.

[0024] The fixing mechanism 3 includes an air pump 34. A plurality of air channels 312 are formed on the fixing base 31. One end of the air channel 312 communicates with the fixing groove 311, and the other end communicates with the input end of the air pump 34 through a hose. The air pump 34 is used to extract air from the fixing groove 311 or supply air to the fixing groove 311. When the air pump 34 extracts air, a negative pressure environment is formed in the fixing groove 311 to adsorb the single-crystal edge skin, making the single-crystal edge skin firmly fixed. After the cleaning is completed, the air pump 34 supplies air to the fixing groove 311, causing the single-crystal edge skin to float for easy removal.

[0025] The cleaning machine further includes a spraying mechanism 4, which is fixedly connected to the housing 1. The spraying mechanism 4 is located in the cleaning chamber 11. The spraying mechanism 4 includes a plurality of spray heads 41. The spraying mechanism 4 further includes a water pump, and the output end of the water pump communicates with the spray heads 41. The spray heads 41 spray the cleaning liquid.

[0026] During use, the single-crystal edge skin to be cleaned is placed in the fixing groove 311 of the fixing base 31. The air pump 34 is started to extract the air in the fixing groove 311, so that the single-crystal edge skin is adsorbed in the fixing groove 311. The slider 33 is started to drive the single-crystal edge skin to move from the input end to the output end of the cleaning chamber 11. Since the cleaning rollers 21 are arranged in a gradually decreasing height order, the cleaning rollers 21 can contact the single-crystal edge skin to different degrees, thereby improving the cleaning effect. At first, the cleaning rollers 21 with a lower contact degree can remove the impurities on the surface of the single-crystal edge skin, avoiding surface scratches on the single-crystal edge skin during the subsequent cleaning by the cleaning rollers 21.
