Description

Technical Field

[0001] The present application relates to the technical field of cleaning devices, and particularly to a turnover device for cleaning a flower basket. Background Art

[0002] The installed capacity demand in the Chinese photovoltaic market has been growing rapidly. During the processing and production of crystalline silicon solar cells, wafers need to be transported using a flower basket as a carrier throughout the entire production process. A number of wafers are loaded into the flower basket for operations such as transportation and cleaning.

[0003] During the wafer cleaning process, it is necessary to manually insert wafers to fill the cleaning basket, that is, fill the flower basket. After filling the flower basket with wafers, the flower basket filled with wafers is cleaned with clean water and then dried. In order to improve the cleaning efficiency of the flower basket, on the basis of the existing 4-basket design, the flower basket has been upgraded to a double-layer flower basket that can hold 100 wafers. There is a current tunnel drying device that uses multiple transmission lines to simultaneously achieve the automated drying of multiple flower baskets, greatly improving the drying efficiency of the flower baskets. In order to enable the wafers in the upper and lower layers to be evenly dried, after the flower basket is cleaned, the flower basket needs to be turned over so that the flower basket rotates from a vertical state to a horizontal state and enters the tunnel. However, since there are a large number of wafers in the flower basket, if the method of manually turning over the flower basket is used, the turning process is unstable, and tools such as a crane are required to achieve the turning of the flower basket, resulting in a low efficiency during the transfer process between cleaning and drying. Summary of the Utility Model

[0004] The technical problem to be solved by the present utility model is that in the existing cleaning process of a flower basket loaded with wafers, the transfer efficiency between cleaning and drying is relatively low.

[0005] Therefore, the present utility model provides a turnover device for cleaning a flower basket.

[0006] The technical solution adopted by the present utility model to solve its technical problem is:

[0007] A turnover device for cleaning a flower basket includes

[0008] a cleaning tank, a mounting frame, and

[0009] a limiting bar, the limiting bar is rotatably arranged in the cleaning tank through a connecting shaft;

[0010] a driven wheel, the driven wheel is coaxially connected to the connecting shaft;

[0011] a driving wheel, the driving wheel is rotatably connected to the mounting frame, the driving wheel is located above the driven wheel, and the driving wheel and the driven wheel are driven by a transmission belt;

[0012] The protective shell is arranged in the cleaning tank. The protective shell divides the cleaning tank into a transmission chamber and a main tank chamber. The protective shell covers the driven wheel and the conveyor belt in the cleaning tank.

[0013] Furthermore, a plug board is inserted into the protective shell, and the connecting shaft is rotatably connected to the plug board.

[0014] Furthermore, a plugging groove is formed in the side wall of the protective shell facing the limiting bar. The plugging groove penetrates through the vertical upward side wall of the protective shell. A through groove is formed at the bottom of the plugging groove, and the through groove penetrates through the protective shell. The opening area of the through groove is smaller than the bottom area of the plugging groove. The through groove is communicated with the plugging groove to form a plug slot. The cross-section of the plug board in the horizontal plane is adapted to the cross-section of the plug slot in the horizontal plane.

[0015] Furthermore, a limiting groove is arranged on the bottom surface of the plugging groove, and a sealing strip is arranged in the limiting groove. The sealing strip forms a seal between the plug board and the protective shell.

[0016] Furthermore, the plug board and the protective shell are fixedly connected by bolts.

[0017] Furthermore, the conveyor belt is made of PVDF material.

[0018] Furthermore, an intermediate wheel is rotatably connected to the mounting bracket. The intermediate wheel is located between the driving wheel and the driven wheel. The conveyor belt is sleeved on the driving wheel, the driven wheel and the intermediate wheel.

[0019] The beneficial effect of the present utility model is that in this application, the stable flipping of the connecting shaft and the limiting bar is controlled through the pulley structure, realizing the automatic flipping of the flower basket, preparing for the subsequent drying process, and thus improving the efficiency of the transfer process between cleaning and drying.

[0020] And in this application, the conveyor belt is made of PVDF material, so it is not easily affected by the alkaline substances washed off from the flower basket in the cleaning liquid. Compared with the metal conveyor belt, it is not easy to generate metal ions that affect the cleaning of the silicon wafer. And the conveyor belt is separated from the limiting bar by the protective shell, so that the debris generated during the operation of the conveyor belt is not easily introduced into the main tank chamber, thus affecting the cleaning of the flower basket.

[0029] Referring to Figures 1-3 , a flipping device for flower basket cleaning includes a cleaning tank 1, a mounting frame 2, a limiting bar 3, and a flipping assembly 4. The flipping assembly 4 includes a driving source 41, a driving wheel 42, a driven wheel 43, and a transmission belt 44.

[0030] The limiting bar 3 is located inside the cleaning tank 1. The limiting bar 3 is rotatably connected to the cleaning tank 1 through a connecting shaft. The driven wheel 43 is located inside the cleaning tank 1, and the driven wheel 43 is coaxially connected to one end of the connecting shaft.

[0031] It should be noted that a protective shell 5 is connected to the inner side wall of the cleaning tank 1. The protective shell 5 covers the driven wheel 43 and the transmission belt 44 inside the cleaning tank 1. The protective shell 5 divides the cleaning tank 1 into a transmission chamber and a main tank chamber.

[0032] On the side wall of the protective shell 5 facing the limiting bar 3, there is a plug-in slot 51. The plug-in slot 51 penetrates the vertically upward side wall of the protective shell 5. At the bottom of the plug-in slot 51, there is a through slot 52. The through slot 52 penetrates the protective shell 5. The slot area of the through slot 52 is smaller than the bottom area of the plug-in slot 51. The through slot 52 is communicated with the plug-in slot 51 to form a plug slot. On the bottom surface of the plug-in slot 51, there is a limiting slot 53. A sealing strip 54 is arranged in the limiting slot 53. An insertion plate 6 is inserted into the protective shell 5 through the plug slot. The cross-section of the insertion plate 6 in the horizontal plane is adapted to the cross-section of the plug slot in the horizontal plane. The sealing strip 54 forms a seal between the insertion plate 6 and the protective shell 5. The insertion plate 6 and the protective shell 5 are fixedly connected by bolts. The connecting shaft is rotatably connected to the insertion plate 6. The driven wheel 43 is coaxially connected to one end of the connecting shaft located in the transmission chamber.
