Description

Technical Field

[0001] The utility model relates to the technical field of isolation mechanisms, and particularly to an isolation mechanism for a texturing device. Background Art

[0002] Texturing devices are mainly used for surface treatment of silicon wafers in the photovoltaic industry to form a textured surface structure. This structure can reduce the surface reflection of light and increase the chance of light entering the solar cell, thereby improving the photoelectric conversion efficiency of the cell.

[0003] The texturing process usually includes multiple steps such as pickling, pure water cleaning, damage removal, and texturing. The design and working principle of the texturing device are crucial for improving the quality and performance of the final product. Since acidic gases generated during pickling treatment will be emitted into the device interior and then affect the textured surface, in current existing texturing devices, to avoid the influence of acidic gases, generally, a partition isolation method is adopted to separately install the pickling and pure water cleaning devices from other devices. Although it can avoid the influence of acidic gases.

[0004] However, since the partition is welded inside the device, it affects the free movement space, making it inconvenient for staff to transfer silicon wafers and for industrial robots to grasp. At the same time, the acidic gases emitted into the device interior are not treated, resulting in the remaining acidic gases still having a certain impact on the textured surface, thereby reducing the product quality. Therefore, an isolation mechanism for a texturing device is proposed to solve the above-mentioned problems. Summary of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides an isolation mechanism for a texturing device, which solves the problems that it is inconvenient for staff to transfer silicon wafers and for industrial robots to grasp, and at the same time, the acidic gases emitted into the device interior are not treated, resulting in the remaining acidic gases still having a certain impact on the textured surface, thereby reducing the product quality.

[0006] To achieve the above object, the utility model provides the following technical solution: An isolation mechanism for a texturing device includes a texturing device body and a control console, and an isolation treatment mechanism is arranged inside the texturing device body;

[0007] The isolation processing mechanism includes guide rails fixedly installed at the top and bottom of the texturing equipment body. A baffle is slidably connected to the inner side of the guide rails. A cylinder is fixedly installed on the back of the texturing equipment body. The output shaft of the cylinder is fixedly connected to a connecting plate, and the front of the connecting plate is fixedly connected to the back of the baffle. A liquid storage tank and a first hood are fixedly connected to the left side of the texturing equipment body. Sodium hydroxide solution is provided inside the liquid storage tank. An electric heating tube is fixedly installed inside the liquid storage tank. An air outlet pipe is fixedly connected to the right side of the top of the liquid storage tank, and the air outlet pipe is connected to the first hood. An air outlet fan is fixedly installed inside the first hood, and a plurality of air outlet holes are provided on the right side of the first hood.

[0008] Furthermore, a second hood is fixedly connected to the top of the texturing equipment body, and an exhaust fan is fixedly installed inside the second hood.

[0009] Furthermore, the control console is electrically connected to the texturing equipment body, the cylinder, the electric heating tube, the air outlet fan, and the exhaust fan. An outlet is provided on the top of the second hood, and a protective net is fixedly connected to the inner side of the outlet.

[0010] Furthermore, a moving port is provided on the back of the texturing equipment body. The inner diameter of the moving port is larger than the thickness of the baffle, and the baffle passes through the moving port.

[0011] Furthermore, an adding pipe is fixedly connected to the right side of the top of the liquid storage tank, and a sealing cover is threadedly connected to the top of the adding pipe.

[0014] Compared with the prior art, the present utility model provides an isolation mechanism for a texturing equipment, which has the following beneficial effects:

[0015] 1. The isolation mechanism of the texturing equipment can, by setting up an isolation treatment mechanism, facilitate the transfer of silicon wafers by workers and the grasping by industrial robots without using the partition isolation method while ensuring the isolation effect. When acidic gas is about to spread into the equipment interior, the worker first needs to start the cylinder to retract its output shaft, thereby driving the baffle to slide forward inside the guide rail through the connecting plate, so as to hermetically isolate the pickling and pure water cleaning equipment from other equipment and prevent the acidic gas from further expanding its influence range. Then, start the electric heating tube to heat and evaporate the sodium hydroxide solution in the liquid storage tank, thus generating sodium hydroxide aerosol. Subsequently, the sodium hydroxide aerosol will be introduced into the interior of the first hood through the air outlet pipe. At this time, start the air outlet fan, and with the cooperation of the air outlet holes, the sodium hydroxide aerosol can be introduced into the area of the pickling and pure water cleaning equipment, so that the sodium hydroxide aerosol reacts with the acidic gas to form harmless salts or water, avoiding the mixing and residue of the mist from affecting the texture surface and passivation effect, and further improving the product quality.

[0016] 2. The isolation mechanism of the texturing equipment, through the cooperation of the second hood and the exhaust fan, after the reaction is completed, starting the exhaust fan can discharge the excess sodium hydroxide aerosol and the residual acidic gas together to the main body of the texturing equipment, thus further reducing the influence.

[0025] The isolation treatment mechanism includes guide rails 3 fixedly installed at the top and bottom of the texturing device body 1. A baffle 4 is slidably connected to the inner side of the guide rails 3. A cylinder 5 is fixedly installed on the back of the texturing device body 1. The output shaft of the cylinder 5 is fixedly connected to a connecting plate 6. The front surface of the connecting plate 6 is fixedly connected to the back surface of the baffle 4. A liquid storage tank 7 and a first hood 11 are fixedly connected to the left side of the texturing device body 1. Sodium hydroxide solution is arranged inside the liquid storage tank 7. An electric heating tube 8 is fixedly installed inside the liquid storage tank 7. An air outlet pipe 9 is fixedly connected to the right side of the top of the liquid storage tank 7. The air outlet pipe 9 is connected to the first hood 11. An air outlet fan 12 is fixedly installed inside the first hood 11. A plurality of air outlet holes 13 are opened on the right side of the first hood 11. When acidic gas is about to be emitted into the device interior, the staff first needs to start the cylinder 5 to retract its output shaft, thereby driving the baffle 4 to slide forward inside the guide rails 3 through the connecting plate 6, so as to seal off the pickling and pure water cleaning equipment from other equipment, and avoid the continuous expansion of the influence range of the acidic gas.

[0026] Then start the electric heating tube 8 to heat and evaporate the sodium hydroxide solution inside the liquid storage tank 7, thereby generating sodium hydroxide aerosol. Subsequently, the sodium hydroxide aerosol will be introduced into the first hood 11 through the air outlet pipe 9. At this time, start the air outlet fan 12, and with the cooperation of the air outlet holes 13, the sodium hydroxide aerosol can be introduced into the pickling and pure water cleaning equipment area, so that the sodium hydroxide aerosol reacts with the acidic gas to form harmless salts or water, avoiding the mixing and residue of the mist from affecting the surface texture and passivation effect, and thus improving the product quality.

[0027] Among them, a moving port 16 is opened on the back of the texturing device body 1. The inner diameter size of the moving port 16 is larger than the thickness size of the baffle 4. The baffle 4 passes through the moving port 16. By providing the moving port 16, it is convenient for the baffle 4 to move back and forth.

[0028] In addition, a filling pipe 10 is fixedly connected to the right side of the top end of the liquid storage tank 7. A sealing cover 17 is threadedly connected to the top of the filling pipe 10. By providing the filling pipe 10 and the sealing cover 17, it is convenient for the staff to add sodium hydroxide solution into the liquid storage tank 7.

[0029] Embodiment 2:

[0030] Please refer to Figure 1 、 Figure 3 and Figure 4 On the basis of Embodiment 1, a second hood 14 is fixedly connected to the top of the texturing equipment body 1. An exhaust fan 15 is fixedly installed inside the second hood 14. Through the cooperation of the second hood 14 and the exhaust fan 15, after the reaction is completed, the exhaust fan 15 is started, and the excess sodium hydroxide aerosol and the residual acidic gas can be discharged into the texturing equipment body 1 together, thereby further reducing the impact.

[0031] Among them, the control console 2 is electrically connected to the texturing equipment body 1, the cylinder 5, the electric heating tube 8, the air outlet fan 12 and the exhaust fan 15. An outlet 18 is opened at the top of the second hood 14. A protective net 19 is fixedly connected to the inner side of the outlet 18. By providing the control console 2, it is convenient for the staff to control the start and stop of each device, and the protective net 19 can also prevent sundries from entering the inside of the second hood 14.

[0032] It should be noted that cushion blocks 20 are fixedly connected to the bottoms of both the texturing equipment body 1 and the control console 2. Baffle plates 21 are fixedly connected to the front and back of the texturing equipment body 1. By providing the cushion blocks 20 and the baffle plates 21, the texturing equipment body 1 and the control console 2 are raised and a simple water blocking effect is achieved.

[0033] In addition, a plurality of protective doors 22 are installed on the front of the texturing equipment body 1 through hinges. An observation window 23 is provided on the front of the protective door 22. By providing the protective doors 22 and the observation window 23, it is convenient for the staff to enter and exit and observe.

[0034] The working principle of the above embodiments is as follows:

[0035] When acidic gas is about to disperse into the interior of the equipment, the staff first need to start the cylinder 5 to retract its output shaft. Thus, the baffle 4 is driven to slide forward inside the guide rail 3 through the connecting plate 6, so that the pickling and pure water cleaning equipment is hermetically isolated from other equipment, avoiding the continuous expansion of the influence range of the acidic gas. Then, the electric heating tube 8 is started to heat and evaporate the sodium hydroxide solution inside the liquid storage tank 7, thereby generating sodium hydroxide aerosol. Subsequently, the sodium hydroxide aerosol will be introduced into the interior of the first hood 11 through the air outlet pipe 9. At this time, when the air outlet fan 12 is started, with the cooperation of the air outlet hole 13, the sodium hydroxide aerosol can be introduced into the area of the pickling and pure water cleaning equipment, so that the sodium hydroxide aerosol reacts with the acidic gas to form harmless salts or water. Among them, after the reaction is completed, the electric heating tube 8 and the air outlet fan 12 are turned off, and then the exhaust fan 15 is started, and the excess sodium hydroxide aerosol and the remaining acidic gas can be discharged together to the texturing equipment body 1, thus further reducing the influence. When almost all is discharged, the output shaft of the cylinder 5 is pushed forward, so that the baffle 4 is driven to slide backward inside the guide rail 3 through the connecting plate 6, and then the hermetic isolation between the pickling and pure water cleaning equipment and other equipment is released, which is convenient for the staff to transfer the silicon wafers and for the industrial robot to grasp.
