Description

Technical Field

[0001] The invention relates to the technical field of cleaning and degumming, and more specifically to a cleaning and degumming device for photovoltaic silicon wafers. Background Art

[0002] In the photovoltaic industry, the cleanliness of silicon wafers directly affects the conversion efficiency and overall performance of the battery. Since various impurities such as metal powder, silicon powder, silicon carbide and cutting fluid will adhere to silicon wafers during the production process, if these residues are not completely removed, it will cause the battery performance to decline or even damage. Therefore, the use of effective cleaning and degumming technology is crucial to improving the quality of silicon wafers.

[0003] As shown in the prior art of publication number CN116454012B, although the prior art drives the upper and lower movable turntables to rotate synchronously through the transmission rod, the movable turntable drives the two double-rod movable frames to move synchronously inward through the connecting rod, and the photovoltaic silicon wafer is clamped and fixed by the double-rod movable frame, thereby ensuring the clamping and fixing effect of the double-rod movable frame on the photovoltaic silicon wafer. However, when installing the photovoltaic silicon wafer, the photovoltaic silicon wafer is initially supported by only one end of multiple transmission rods, which causes the photovoltaic silicon wafer to be unevenly stressed and easily distorted. At the same time, after the photovoltaic silicon wafer is placed and fixed, one end of the photovoltaic silicon wafer is still unrestricted, which requires the staff to use bolts to limit and fix it, thereby increasing the operation steps and affecting the operation efficiency.

[0004] Moreover, when cleaning photovoltaic silicon wafers, this technical solution can only stir the solution to flush and clean the photovoltaic silicon wafers. This cleaning method uses the impact force of the water flow to clean the photovoltaic silicon wafers. Due to the limited impact force of the solution, it cannot fully clean the glue spots on the photovoltaic silicon wafers, which will affect the cleaning effect of this technical solution. Summary of the invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a photovoltaic silicon wafer cleaning and degumming device, which drives the main gear to rotate by operating a screw threadedly connected to the packaging barrel, and the main gear then drives the two fixed columns to rotate synchronously with the help of two meshing slave gears.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Refer to the instruction manual Figure 1-7 The present invention provides a photovoltaic silicon wafer cleaning and degumming device, comprising a base 1, a tank body 2 for cleaning photovoltaic silicon wafers is installed on the top of the base 1, and a plurality of mounting parts for conveniently taking and placing photovoltaic silicon wafers are arranged inside the tank body 2;

[0034] like Figure 2-4As shown, each set of mounting parts includes a top plate 3 and a bottom plate 4 arranged in the tank body 2, and the top plate 3 is arranged on the top of the bottom plate 4, four supporting columns 5 distributed in a rectangular array are installed between the top plate 3 and the bottom plate 4, and the inner side walls of the four supporting columns 5 are provided with a plurality of slots 6 for supporting photovoltaic silicon wafers; two fixing columns 7 movably connected by bearings are installed between the top plate 3 and the bottom plate 4, and a clamping column 8 is installed on the side of the fixing column 7 close to the photovoltaic silicon wafer, and a clamping hole 9 is opened on the side of the clamping column 8 close to the photovoltaic silicon wafer; vertical shafts 10 are installed on the top of the two fixing columns 7, and the top of the vertical shaft 10 extends to the top of the top plate 3 and is installed with a slave gear 11, and between the two slave gears 11 The main gear 12 is meshed with each other, and the thickness of the main gear 12 is greater than that of the slave gear 11. A packaging tube 13 is provided on the top of the main gear 12. The bottom end of the packaging tube 13 is fixed to the bottom of the top plate 3, and a screw 14 is provided on the top of the packaging tube 13. The bottom end of the screw 14 penetrates the packaging tube 13 and is fixed to the top of the main gear 12, and the outside of the screw 14 is threadedly connected with the inside of the packaging tube 13. Because handles 31 are provided on both sides of the screw 14, and the bottoms of both ends of the handles 31 are fixed to the top of the packaging tube 13, the staff can operate the handles 31 to hold the installation part, thereby improving the convenience of the staff to operate the installation part.

[0035] Since the thickness of the main gear 12 is greater than that of the slave gear 11, the main gear 12 can still maintain a meshing relationship with the slave gear 11 during the upward and downward displacement;

[0036] When in use, when the staff operates the screw 14 threadedly connected to the packaging tube 13 to rotate, the main gear 12 can be driven to rotate forward, and the main gear 12 simultaneously drives the two fixed columns 7 to rotate outward synchronously through the two meshing slave gears 11, so that the fixed columns 7 can drive the multiple clamping columns 8 to turn outward, so that it is convenient for the staff to place the photovoltaic silicon wafers in the multiple support columns 5 from front to back;

[0037] Afterwards, the main gear 12 is reversed to drive the two meshing slave gears 11 to rotate, thereby driving the fixing column 7 connected to the slave gear 11 to rotate inward, so that the clamping column 8 on the two fixing columns 7 can position the photovoltaic silicon wafer front and back, and achieve the effect of all-round positioning of the photovoltaic silicon wafer. In addition, by means of the threaded connection between the screw rod 14 and the packaging tube 13, the main gear 12 can be displaced by operating the screw rod 14, and the main gear 12 can also be limited and fixed.

[0038] After installation, the staff places the mounting piece inside the tank body 2 through the material hole 25, and engages the positioning hole 18 on the bottom plate 4 with the positioning plate 17, so that the photovoltaic silicon wafer can move with the support plate 15 to achieve the effect of cleaning and degumming.

[0039] To improve the cleaning effect of photovoltaic silicon wafers, Figure 2 , 4 As shown in , 6 and 7, a support plate 15 is provided inside the bottom end of the tank body 2, and the bottom end of the support plate 15 is movably connected to the bottom of the inner cavity of the tank body 2 through a rotating shaft, and the bottom plate 4 is arranged on the top of the support plate 15; a support seat 16 movably connected through a rotating shaft is installed on the side of the top of the support plate 15 corresponding to the bottom plate 4, a positioning plate 17 is installed on the top of the support seat 16, and a positioning hole 18 is opened on the side of the bottom plate 4 corresponding to the positioning plate 17, and the top of the positioning plate 17 extends to the inside of the positioning hole 18; a gear ring 19 is provided at the bottom of the support plate 15, and a plurality of connecting columns 21 for the tank body 2 are installed outside the gear ring 19, and a plurality of auxiliary gears 20 distributed at intervals are meshed inside the gear ring 19, and the positions of the auxiliary gears 20 and the support seat 16 correspond to each other up and down, and a linkage shaft 22 is installed on the top of the auxiliary gear 20, and the top of the linkage shaft 22 passes through the support plate 15 and is fixed to the rotating shaft on the support seat 16;

[0040] The support plate 15 drives the bottom plate 4 to rotate by the engagement of the positioning plate 17 and the positioning hole 18 on the support seat 16, so that the photovoltaic silicon wafer on the mounting piece can be rotated together with the support plate 15, so as to achieve the effect of cleaning and degumming the photovoltaic silicon wafer. In addition, because the support seat 16 is movably connected to the support plate 15 through the rotating shaft, when the support seat 16 rotates with the support plate 15, it can rotate by the meshing of the auxiliary gear 20 and the ring gear 19, and then drive the photovoltaic silicon wafer on the mounting piece to rotate, so as to achieve the effect of the photovoltaic silicon wafer rotating while revolving with the support plate 15, thereby improving the degumming effect and degumming efficiency. In addition, because a servo motor 23 is installed on the top of the inner cavity of the base 1, and the output shaft of the servo motor 23 passes through the base 1 and the tank body 2 in sequence and is fixed to the rotating shaft on the support plate 15, the servo motor 23 can drive the support plate 15 to drive the photovoltaic silicon wafer on the mounting piece to rotate.

[0041] In order to enable the bottom plate 4 to rotate with the support seat 16, Figure 4 , 6 As shown in 7, the cross-section of the positioning plate 17 and the cross-section of the positioning hole 18 are both set to be rectangular, and the outer side of the positioning plate 17 is in contact with the inner wall of the positioning hole 18. Since the cross-section of the positioning plate 17 and the cross-section of the positioning hole 18 are both rectangular, the positioning plate 17 can limit the positioning hole 18, thereby allowing the base plate 4 to rotate with the support seat 16, thereby achieving the effect of operating the photovoltaic silicon wafer to rotate.

[0042] In order to improve the stability of the installation parts, it is necessary to limit the installation parts, such as Figure 1 , 2As shown in Figure 5, a limiting ring 26 is provided on the side of the top of the movable plate 24 corresponding to the packaging tube 13, and the bottom end of the limiting ring 26 is installed on the top of the movable plate 24 through a bearing; a plurality of spaced limiting plates 27 are installed on the outside of the packaging tube 13, and a limiting hole 28 is provided on the side of the limiting plate 27 corresponding to the limiting ring 26, and the limiting plate 27 extends to the inside of the limiting hole 28 at one end away from the packaging tube 13. By cooperating with the limiting plate 27 and the limiting hole 28, the packaging tube 13 can be engaged and limited, so as to facilitate the installation of the mounting part. At the same time, by limiting the positioning of the limiting ring 26, the mounting part can be prevented from being detached. Because the inner diameter of the limiting ring 26 is larger than the diameter of the material hole 25, the limiting ring 26 will not affect the taking and placing operation of the mounting part.

[0043] In order to facilitate the delivery and output of solutions used to clean photovoltaic silicon wafers, such as Figure 1 , 2 As shown in Figure 5, a discharge pipe 29 is fixedly connected to the front side of the bottom end of the tank body 2, and a feed pipe 30 is provided on the top of the discharge pipe 29. The feed pipe 30 is installed on the top of the movable plate 24, and the feed pipe 30 is fixedly connected to the movable plate 24. The solution is transported to the inside of the tank body 2 through the feed pipe 30 to achieve the effect of cleaning and degumming the photovoltaic silicon wafers, and then the waste liquid is discharged through the discharge pipe 29.

[0044] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
