Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic chain transmission, in particular to a photovoltaic chain cleaning and drying transmission device. Background Art

[0002] In the existing transmission technology, the fixing method of the transmission roller is not reasonable enough. It is common to press a fixing strip above all the bearing covers on one side for unified fixing. The bearing pressing block under this fixing method is made into a whole, which makes it extremely inconvenient to disassemble a single transmission roller. Once a problem occurs in a transmission roller, it will take a lot of time and energy to debug and repair it, and the processing accuracy is difficult to ensure, resulting in deviation of the transmission roller during the transportation of silicon wafers, affecting the smooth transportation of silicon wafers. In the process of cleaning and drying silicon wafers, since silicon wafers are very easy to break, they cannot be squeezed at will. At the same time, during the transportation of silicon wafers, silicon wafers cannot be subjected to any collision. Therefore, it is very necessary to design a photovoltaic chain cleaning and drying transmission equipment that is easy to disassemble and stabilize the pressing. Utility Model Content

[0026] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-6The utility model provides a technical solution: a photovoltaic chain-type cleaning and drying transmission device, comprising two parallel mounting brackets 100, a power component 200 is installed on one side mounting bracket 100, and a conveying component 300 is installed between the two mounting brackets 100, the power component 200 drives the conveying component 300, and the conveying component 300 includes transmission rollers 301 arranged at equal intervals along the parallel direction of the two mounting brackets 100, and bearings 101 corresponding to each transmission roller 301 are provided on one side mounting bracket 101, and one end of the transmission roller 301 is respectively installed in the corresponding bearing 101 on one side, and a bearing pressure block 102 is provided between the two adjacent bearings 101, and each bearing pressure block 102 disperses and presses the bearing 101.

[0028] By providing a single-removable structure for the bearing block 102, when a component fails and requires repair or replacement, the operator can easily remove the relevant bearing block 102 and the transmission roller 301 without interfering with other normal components. This not only improves the assembly accuracy and maintenance efficiency of the entire equipment, but also reduces processing difficulty, maintenance costs, and equipment downtime. By providing the bearing block 102 connected to the bearing 101, it effectively prevents the poor fixation of the transmission roller 301 from affecting the operating stability and debugging efficiency of the equipment, ensures that the bearing 101 firmly supports the various components on the conveying component, prevents the components from loosening or displacement due to stress, and ensures the integrity and stability of the equipment.

[0029] The power component 200 includes a transmission shaft 201 arranged parallel to the mounting bracket 100 on one side. First bevel gears 202 are arranged at equal intervals on the transmission shaft 201. A second bevel gear 203 is provided at one end of each transmission roller 301. Each first bevel gear 202 is meshed with each second bevel gear 203.

[0030] By setting the first bevel gear 202 and the second bevel gear 203 for meshing transmission, it is ensured that power can be efficiently transmitted to the transmission roller 301, ensuring that the silicon wafer moves smoothly during transportation and avoiding stagnation and collision of the silicon wafer due to insufficient power.

[0031] The power component 200 further includes at least four groups of drive motors 204 , and each group of drive motors 204 drives the transmission shaft 201 to rotate via an independent sprocket 205 and chain 206 structure.

[0032] By setting the drive motor 204 for segmented installation, during the production process, the transmission roller area with lower speed in the front section shortens the spacing between silicon wafers to place more silicon wafers, and then the motor speed in the rear section is increased to widen the spacing between the silicon wafers and restore it to a normal level, thereby effectively increasing production capacity and improving production efficiency. Secondly, during the debugging process, there is no need to perform horizontal calibration on the entire equipment at the same time, but it can be calibrated in segments, so as to quickly locate the fault, shorten the debugging cycle, and improve the problem of difficulty in debugging a single motor. Finally, the segmented installation of the motor also reduces the use requirements of the motor and the hexagonal shaft, avoids the hexagonal shaft from slipping due to excessive load, and ensures the stable operation of the equipment.

[0033] The conveying member 300 is provided with a cleaning section in the middle, located within a water tank. The cleaning section comprises a plurality of first upper pressure rods 302 and water-repelling rollers 303 spaced apart. Each first upper pressure rod 302 and water-repelling roller 303 is positioned directly above the drive roller 301, and each first upper pressure rod 302 is provided with a plurality of cylindrical first roller ring assemblies 304. The drive rollers 301 are used to transport silicon wafers, while the first upper pressure rods 302 are used to secure the wafers. Residual acid and alkali solutions on the wafer surfaces are then cleaned in the water tank. The water-repelling rollers 303 then initially remove any remaining moisture from the wafers, facilitating subsequent drying operations.

[0034] Each of the first roller ring groups 304 is composed of at least two roller rings, and at least two groups of the first roller ring groups 304 are evenly distributed on the first upper pressure rod 302 .

[0035] The conveying component is provided with a drying section behind the cleaning section along its conveying direction. The drying section is composed of a plurality of second upper pressure rods 305 and first upper pressure rods 302 staggered at intervals. The first upper pressure rods 302 are arranged one-to-one directly above the transmission roller 301, and the second upper pressure rods 305 are provided with second roller ring groups 306 staggered with any two adjacent first roller ring groups 304.

[0036] A drying pressing roller 307 is provided below the second upper pressing rod 306 and is located in the same plane as the driving rollers 301 . A third roller ring group 308 corresponding to the second roller ring group 306 is provided on the drying pressing roller 307 .

[0037] By providing a roller ring with a cylindrical structure and an upper pressure rod structure, the contact area between the silicon wafer and the drying pressure roller 307 can be increased, and the connection part is reasonably arranged, thereby improving the uniformity of force on the silicon wafer during the drying process, so that in the subsequent cleaning and drying process, the silicon wafer will not be affected by uneven force and the hot air will not be deflected, causing the silicon wafer to break, thereby improving the product yield.

[0038] Each of the second roller ring group 306 and the third roller ring group 308 is composed of at least four roller rings arranged at equal intervals, and the intervals between the roller rings of the second roller ring group 306 are smaller than the intervals between the roller rings of the third roller ring group 308 .

[0039] By arranging the second roller ring group 306 and the third roller ring group 308 in one-to-one correspondence, the contact area with the silicon wafer is increased, so that the force on the silicon wafer can be evenly distributed during the transmission process, effectively avoiding the risk of silicon wafer damage caused by excessive local force.

[0040] A first transmission gear 207 is also provided at one end of the transmission roller 301 and the drying pressure roller 307 located in the cleaning section and the drying section, and a second transmission gear 208 is provided at one end of each of the first upper pressure rod 302, the water-repelling roller 303 and the second upper pressure rod 306, and each first transmission gear 207 is meshed with each second transmission gear 208.

[0041] By setting a driving motor 204 as a power source to drive the sprocket 205 to rotate, the sprocket 205 transmits power to each first bevel gear 202 on the transmission shaft 201 through the transmission chain 206, and each first bevel gear 202 is correspondingly engaged with the second bevel gear 203 to drive the transmission roller 301 to transport the silicon wafer. At the same time, each first transmission gear 207 is connected with the second bevel gear 203 to drive the transmission roller 301 and the drying roller 307 of the cleaning part and the drying part to work together, and each second transmission gear 208 is correspondingly engaged with the first transmission gear 207 to drive the first upper pressure rod 302, the water-repelling roller 303 and the second upper pressure rod 306 to operate in an orderly manner. When the silicon wafer is transported to the cleaning section, the first roller ring group 304 and the transmission roller 301 on the first upper pressure rod 302 are used to fix and transport the silicon wafer, and the acid and alkali liquid remaining on the surface of the silicon wafer is cleaned in the water tank. Then, the water remaining on the silicon wafer is initially intercepted by the water-repelling roller 303, and then it is smoothly transported to the drying section via the first upper pressure rod 302 and the transmission roller 301. Finally, the second roller ring group 306 on the second upper pressure rod 306 and the third roller ring group 308 on the drying pressure roller 307 cooperate to press the silicon wafer so that it can be transported smoothly, thereby preventing the silicon wafer from positional displacement during hot air drying and ensuring the smooth operation of the entire equipment.
