Description

Technical Field

[0001] This application relates to the field of solar cell technology, specifically to a wet preparation apparatus and a solar cell manufacturing production line. Background Technology

[0002] In the wet manufacturing process of solar cells (such as texturing, etching, alkaline polishing, etc.), a chemical storage container is usually required to replenish the chemical solution to ensure the continuous wet manufacturing process.

[0003] With prolonged operation of the wet preparation process, chemical crystal deposits or flocculent suspensions can easily form in the drug storage container, causing blockages in the pipelines that connect to the drug storage container and supply the drug to the preparation tank. This affects the supply function, leading to abnormalities in the wet preparation process and an increase in the product defect rate.

[0004] Currently, the common method for cleaning chemical crystal deposits or flocculent suspensions is to shut down the machine, disassemble the drug storage container, rinse the chemical crystal deposits or flocculent suspensions in the drug storage container, and use other tools to unclog the pipeline for replenishing the drug. This cleaning method is time-consuming and leads to a decrease in production capacity. Utility Model Content

[0005] Therefore, it is necessary to provide a wet process preparation device and a solar cell manufacturing production line that can improve production capacity to address the above problems.

[0011] In some embodiments, the wet preparation apparatus further includes multiple outer shells, each corresponding to a liquid medicine storage container. The liquid medicine storage container is disposed inside the corresponding outer shell, and a hot water insulation cavity is defined between the outer wall of the liquid medicine storage container and the inner wall of the corresponding outer shell. The second pipe assembly is used to guide the hot water in the hot water storage cavity to each of the hot water insulation cavities.

[0012] In some embodiments, the second pipeline assembly includes an output main pipe, a plurality of supply branch pipes and a plurality of supply branch valves. The output main pipe is connected to the hot water storage chamber. The supply branch valves and the hot water insulation chamber are each corresponding to a supply branch pipe. The supply branch pipes are connected to the output main pipe and the corresponding hot water insulation chamber. The supply branch valves are connected to the corresponding supply branch pipes.

[0013] In some embodiments, the wet preparation apparatus further includes a third piping assembly for guiding the hot water in each of the hot water insulation chambers back to the hot water storage chamber.

This method saves cleaning time and greatly increases production capacity. Attached Figure Description

However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0029] In the wet manufacturing process of solar cells (such as texturing, etching, alkaline polishing, etc.), a chemical storage container is usually required to replenish the chemical solution to ensure the continuous wet manufacturing process.

[0030] With prolonged operation of the wet preparation process, chemical crystal deposits or flocculent suspensions can easily form in the drug storage container, causing blockages in the pipelines that connect to the drug storage container and supply the drug to the preparation tank. This affects the supply function, leading to abnormalities in the wet preparation process and an increase in the product defect rate.

[0031] Currently, the common method for cleaning chemical crystal deposits or flocculent suspensions is to shut down the machine, disassemble the drug storage container, rinse the chemical crystal deposits or flocculent suspensions in the drug storage container, and use other tools to unclog the pipeline for replenishing the drug. This cleaning method is time-consuming and leads to a decrease in production capacity.

[0032] To alleviate the aforementioned problems, the applicant, after in-depth research, designed a wet preparation apparatus 100, which includes a preparation body 7, multiple liquid medicine storage containers 4, a hot water storage container 16, multiple first pipe assemblies, and second pipe assemblies. The preparation body 7 has a preparation tank 71, the liquid medicine storage containers 4 have liquid medicine storage chambers 41, the hot water storage containers 16 have hot water storage chambers 161, and the first pipe assemblies correspond one-to-one with the liquid medicine storage containers 4. The first pipe assemblies are used to guide the fluid in the corresponding liquid medicine storage chamber 41 to flow into the preparation tank 71, and the second pipe assemblies are used to guide the hot water in the hot water storage chambers 161 to flow into each liquid medicine storage chamber 41 to clean each liquid medicine storage chamber 41.

[0033] Specifically, the wet processing apparatus 100 refers to an apparatus that uses a chemical solution to perform operations such as texturing, etching, and alkaline polishing on solar cells. The wet processing apparatus 100 can be a texturing apparatus, an etching apparatus, an alkaline polishing apparatus, etc. A texturing apparatus is an apparatus that forms a textured surface on the solar cell to reduce its reflectivity and thus increase light absorption. An etching apparatus is an apparatus that uses a chemical reaction between a chemical solution and the surface material of the solar cell to selectively remove contaminants, thereby achieving cleaning and modification. An alkaline polishing apparatus is an apparatus that can remove contaminants from the surface of the solar cell and improve its surface quality, thereby increasing the photoelectric conversion efficiency of the solar cell.

[0034] The preparation body 7 has a preparation tank 71, which is used to contain the pharmaceutical solution and the battery cells, and provides a place for the reaction between the pharmaceutical solution and the battery cells. It is preferably made of a material resistant to acid and alkali corrosion. The shape of the preparation tank 71 can be set as a rectangular tank, a circular tank, or other tank structures according to requirements. Generally, the preparation tank 71 is a rectangular tank, as this type of tank structure is easy to form.

[0035] The medicine storage container 4 is usually a constant pressure tank, and the medicine storage chamber 41 inside it is a constant pressure chamber. The constant pressure chamber is used to hold the medicine and output the medicine at a constant pressure to improve the stability of the medicine output.

[0036] Depending on the type of wet preparation, the drug solution storage container 4 can be configured as two, three, or even more. Taking the wet preparation process of texturing as an example, there are two drug solution storage containers 4, one of which contains alkali and the other contains additives. The alkali and additives used in texturing are conventional techniques in this field, so specific examples will not be given here. In actual wet preparation processes, chemical crystallization deposition is prone to occur in the drug solution storage container 4 containing alkali, and flocculent suspensions are prone to form in the drug solution storage container 4 containing additives.

[0037] In some embodiments, the wet preparation apparatus 100 further includes an inlet valve 1 and an inlet pipe 2, each corresponding to a drug solution storage container 4. The inlet pipe 2 communicates with the drug solution source and the corresponding drug solution storage chamber 41 of the drug solution storage container 4. The inlet valve 1 is installed on the corresponding inlet pipe 2 and is used to open and close the inlet pipe 2. When the inlet valve 1 is open, the drug solution in the drug solution source flows into the drug solution storage chamber 41 through the inlet pipe 2, replenishing the drug solution storage chamber 41. The hot water storage container 16 is used to store hot water and to supply hot water to each drug solution storage container 4.

[0038] In some embodiments, the wet preparation apparatus 100 further includes a water heater, a water inlet pipe 14, and a water inlet valve 15. The water inlet pipe 14 connects the water outlet of the water heater and the hot water storage chamber 161, and the water inlet valve 15 is connected to the water inlet pipe 14. When the water inlet valve 15 is open, the heated hot water in the water heater is input through the water inlet pipe 14 and stored in the hot water storage chamber 161.

[0039] In some embodiments, the wet preparation apparatus 100 further includes a heating element and a temperature sensor. The heating element is electrically connected to the temperature sensor, which is installed on the hot water storage container 16 and used to detect the temperature of the hot water in the hot water storage chamber 161. The heating element is configured to turn on when the temperature of the hot water in the hot water storage chamber 161 is lower than a first set temperature, and is configured to turn off when the temperature of the hot water in the hot water storage chamber 161 is higher than a second set temperature, wherein the first set temperature is lower than the second set temperature.

[0040] Specifically, the wet preparation apparatus 100 also includes a controller, which is electrically connected to a temperature sensor and a heating element. The temperature sensor feeds back the temperature of the hot water in the hot water storage chamber 161 to the controller. The controller compares the temperature of the hot water with a first set temperature and a second set temperature, and controls the heating element to start or stop based on the comparison result.

[0041] By combining the heating element and the temperature sensor, the hot water in the hot water storage chamber 161 can be maintained within a constant temperature range, specifically between the first set temperature and the second set temperature range, so as to achieve a better cleaning effect when cleaning the medicine storage chamber 41 later.

[0042] Of course, in some other embodiments, the water heater can be omitted. The water inlet pipe 14 is connected between the cold water source and the hot water storage chamber 161. The cold water in the cold water source is introduced into the hot water storage chamber 161 through the water inlet pipe 14 and heated by the heating element to form hot water.

[0043] The wet preparation apparatus 100 has a preparation state and a cleaning state. When the wet preparation apparatus 100 is in the preparation state, the first piping assembly guides the fluid in the corresponding drug storage chamber 41 to flow into the preparation tank 71 to replenish the drug in the preparation tank 71, facilitating the continuous wet preparation. When chemical crystal deposits or flocculent suspensions are present in the drug storage container 4, the wet preparation apparatus 100 switches to the cleaning state. The second piping assembly guides the hot water in the hot water storage chamber 161 to flow into the drug storage chamber 41 to clean the drug storage chamber 41 containing chemical crystal deposits or flocculent suspensions. At the same time, the first piping assembly guides the wastewater after cleaning to be discharged into the preparation tank 71 to improve the cleaning effect of the drug storage chamber 41.

[0044] It is understood that the fluids that the first pipeline assembly guides from the corresponding drug storage chamber 41 to the preparation tank 71 include drug solution and wastewater. When the wet preparation device 100 is in the preparation state, the first pipeline assembly guides from the corresponding drug storage chamber 41 to the preparation tank 71. When the wet preparation device 100 is in the cleaning state, the first pipeline assembly guides from the corresponding drug storage chamber 41 to the preparation tank 71.

[0045] In addition, the wet preparation apparatus 100 also has a waste liquid recovery pipe, into which the medicine liquid in the preparation tank 71 is discharged when the liquid is changed. Generally speaking, the wet preparation apparatus 100 switches to the cleaning state when the preparation tank 71 needs to be changed, so that the wastewater discharged from the medicine storage chamber 41 can be discharged into the waste liquid recovery pipe at the same time as the medicine liquid that needs to be replaced in the preparation tank 71.

[0046] In summary, this application utilizes a preparation body 7, multiple drug storage containers 4, a hot water storage container 16, multiple first pipe assemblies, and a second pipe assembly in conjunction. When chemical crystal deposits or flocculent suspensions are present in the drug storage chamber 41 of the drug storage container 4, hot water from the hot water storage chamber 161 can be introduced into the drug storage chamber 41 through the second pipe assembly. The hot water significantly improves the ability to dissolve alkali crystals and flocculent suspensions by providing energy, altering the dissolution balance, and weakening intermolecular forces, thus facilitating efficient cleaning and ensuring the stability of the liquid replenishment in the wet preparation device 100. During the cleaning process, wastewater from the drug storage chamber 41 can be discharged using the first pipe assembly, further improving cleaning efficiency and effectiveness. Under this design, the drug storage container 4 can be automatically cleaned using the hot water storage container 16 and the second pipe assembly, and the wastewater discharged from the drug storage chamber 41 can automatically unclog the first pipe assembly, eliminating the need for manual cleaning of the drug storage container 4 and manual unclogging of the first pipe assembly. This method saves cleaning time and significantly increases production capacity. In addition, since no manual cleaning is required, the risk of on-site staff coming into contact with the solution is reduced, thus improving the safety of the solution.

[0047] In some embodiments, the first pipeline assembly includes an infusion tube 5 and an infusion valve 6. The infusion tube 5 is connected between the corresponding drug storage chamber 41 and the preparation tank 71. The infusion valve 6 is disposed on the infusion tube 5 and is used to control the opening and closing of the infusion tube 5.

[0048] When the wet preparation device 100 is in the preparation state, the infusion valve 6 is opened, and the medicine in the medicine storage container 4 flows into the preparation tank 71 through the infusion pipe 5 to replenish the preparation tank 71. When the wet preparation device 100 is in the cleaning state, the infusion valve 6 is also opened, and the wastewater after cleaning flows into the preparation tank 71 through the infusion pipe 5. During this process, the wastewater flushes the infusion pipe 5 to automatically unclog it. It can be understood that the infusion pipe 5 is the pipeline mentioned above for replenishing the medicine.

[0049] It is worth mentioning that before the wet preparation device 100 is switched to the cleaning state, the remaining medicine in the medicine storage chamber 41 that needs to be cleaned should be drained through the infusion tube 5.

[0050] In this application, by setting up an infusion pipe 5 and an infusion valve 6 in coordination, on-site personnel can control the injection of medicine or sewage into the preparation tank 71 in a timely manner according to the actual working conditions, thereby improving the reliability of the operation of the wet preparation device 100.

[0051] In some embodiments, the second pipeline assembly includes an output main pipe 13, a plurality of cleaning branch pipes 9 and a plurality of cleaning branch valves 8. The output main pipe 13 is connected to the hot water storage chamber 161. The cleaning branch valves 8 and the medicine storage chamber 41 are each corresponding to a cleaning branch pipe 9. One end of the cleaning branch pipe 9 is connected to the output main pipe 13, and the other end of the cleaning branch pipe 9 extends into the corresponding medicine storage chamber 41. The cleaning branch valve 8 is connected to the corresponding cleaning branch pipe 9.

[0052] When the wet preparation apparatus 100 is in the preparation state, all cleaning branch valves 8 are closed to prevent hot water from the hot water storage chamber 161 from entering the drug solution storage chambers 41, which would dilute the drug solution and affect the wet preparation effect. When the wet preparation apparatus 100 is in the cleaning state, the cleaning branch valve 8 corresponding to the drug solution storage chamber 41 that needs to be cleaned is opened, allowing hot water to enter the drug solution storage chamber 41 and clean it. At the same time, the infusion valve 6 corresponding to the drug solution storage chamber 41 is also opened, and the wastewater after cleaning can be discharged through the infusion pipe 5.

[0053] Therefore, by setting up the main output pipe 13, multiple cleaning branch pipes 9 and multiple cleaning branch valves 8, hot water can be selected to be input into the drug storage chamber 41 according to the actual situation, so that wet preparation and cleaning are carried out in different time periods, avoiding mutual interference between wet preparation and cleaning operations.

[0054] In some embodiments, the wet preparation apparatus 100 further includes a sprayer 10, which corresponds one-to-one with the drug storage chamber 41. The sprayer 10 is disposed on the top of the corresponding drug storage chamber 41 and is connected to the corresponding cleaning branch pipe 9. Hot water is sprayed into the drug storage chamber 41 using the sprayer 10, allowing the hot water to diffuse relatively evenly and be directed towards the inner sidewall and bottom wall of the drug storage chamber 41, facilitating a thorough rinsing of the inner sidewall and bottom wall of the drug storage chamber 41 without any dead angles.

[0055] In some embodiments, the wet preparation apparatus 100 further includes a plurality of housings 3, each housing 3 corresponding to a liquid medicine storage container 4. The liquid medicine storage container 4 is disposed inside the corresponding housing 3, and a hot water insulation cavity 31 is defined between the outer wall of the liquid medicine storage container 4 and the inner wall of the corresponding housing 3. The second pipe assembly is used to guide the hot water in the hot water storage cavity 161 to each hot water insulation cavity 31.

[0056] When the wet preparation apparatus 100 is in the preparation state, the second piping assembly guides the hot water in the hot water storage chamber 161 to each hot water insulation chamber 31 to ensure that the medicine in the medicine storage chamber 41 is maintained at a constant temperature, reducing the probability of chemical crystal deposition or flocculent suspension formation. When the wet preparation apparatus 100 is in the cleaning state, the second piping assembly stops inputting hot water into each hot water insulation chamber 31, and instead guides the hot water in the hot water storage chamber 161 to flow at a larger flow rate into each medicine storage chamber 41, thereby helping to improve the rinsing effect.

[0057] In some embodiments, the second pipeline assembly includes an output main pipe 13, a plurality of supply branch pipes 11 and a plurality of supply branch valves 12. The output main pipe 13 is connected to the hot water storage chamber 161. The supply branch valves 12 and the hot water insulation chamber 31 are each corresponding to the supply branch pipes 11. The supply branch pipes 11 are connected to the output main pipe 13 and the corresponding hot water insulation chamber 31. The supply branch valves 12 are connected to the corresponding supply branch pipes 11.

[0058] When the wet preparation apparatus 100 is in the preparation state, the supply branch valve 12 is opened, allowing hot water in the hot water storage chamber 161 to be input into each hot water insulation chamber 31 to keep the medicinal liquid warm. When the wet preparation apparatus 100 is in the cleaning state, the supply branch valve 12 is closed, allowing hot water in the hot water storage chamber 161 to be input into each medicinal liquid storage chamber 41 at a larger flow rate to clean the medicinal liquid storage chamber 41.

[0059] By setting up the main output pipe 13, multiple supply branch pipes 11, and multiple supply branch valves 12, the system can control the introduction or stop of hot water into the hot water insulation chamber 31 according to the state of the wet preparation device 100, thereby improving the reliability of the operation of the wet preparation device 100.

[0060] In some embodiments, the wet preparation apparatus 100 further includes a third piping assembly for guiding the hot water in each hot water insulation chamber 31 back to the hot water storage chamber 161.

[0061] When the wet preparation apparatus 100 is in the preparation state, the third piping assembly guides the hot water in each hot water insulation chamber 31 back to the hot water storage chamber 161, so that the hot water can circulate between the hot water insulation chamber 31 and the hot water storage chamber 161, thereby maintaining the temperature of the medicine in the medicine storage chamber 41 and reducing the risk of chemical crystal deposition or flocculent suspension. When the wet preparation apparatus 100 is in the cleaning state, the third piping assembly stops guiding the hot water in each hot water insulation chamber 31 back to the hot water storage chamber 161.

[0062] In some embodiments, the third piping assembly includes a plurality of recovery branch pipes 18, a plurality of recovery branch valves 17, and an input main pipe 19. The recovery branch valves 17 and the hot water insulation chamber 31 are each corresponding to a recovery branch pipe 18. The recovery branch pipe 18 is connected between the corresponding hot water insulation chamber 31 and the input main pipe 19. The recovery branch valves 17 are connected to the corresponding recovery branch pipes 18. The input main pipe 19 is connected to the hot water storage chamber 161.

[0063] When the wet preparation apparatus 100 is in the preparation state, the recovery branch valve 17 is opened to allow the hot water in the hot water storage chamber 161 to circulate within the hot water insulation chamber 31 and the hot water storage chamber 161, thereby maintaining the temperature of the medicinal liquid in the medicinal liquid storage chamber 41. When the wet preparation apparatus 100 is in the cleaning state, the recovery branch valve 17 is closed to allow the hot water in the hot water storage chamber 161 to be input into each medicinal liquid storage chamber 41 at a larger flow rate to clean the medicinal liquid storage chamber 41.

[0064] By setting up multiple recovery branch pipes 18, multiple recovery branch valves 17, and input main pipe 19, the circulation of hot water in the hot water insulation chamber 31 and the hot water storage chamber 161 can be controlled or stopped according to the state of the wet preparation device 100, thereby improving the reliability of the operation of the wet preparation device 100.

[0065] As an example, the inlet valve 1, water inlet valve 15, infusion valve 6, cleaning branch valve 8, supply branch valve 12, and recovery branch valve 17 can all be manual valves or solenoid valves, which can be set according to requirements. Preferably, the inlet valve 1, water inlet valve 15, infusion valve 6, cleaning branch valve 8, supply branch valve 12, and recovery branch valve 17 are all solenoid valves, and all are electrically connected to the above-mentioned controller, and all are opened or closed by the controller.

[0066] This application also provides a solar cell manufacturing production line, which includes the wet preparation apparatus 100 as described in any of the above embodiments. The solar cell manufacturing production line of this application has the effects of any of the above embodiments, and therefore will not be described again here.

[0067] The aforementioned wet preparation apparatus 100 and solar cell manufacturing production line, through the cooperation of the preparation body 7, multiple liquid storage containers 4, hot water storage container 16, multiple first pipe assemblies, and second pipe assemblies, allows hot water from the hot water storage chamber 161 to be introduced into the liquid storage chamber 41 when chemical crystal deposits or flocculent suspensions are present in the liquid storage chamber 41 of the liquid storage container 4. The hot water significantly improves the ability to dissolve alkali crystals and flocculent suspensions by providing energy, altering the dissolution balance, and weakening intermolecular forces, thus facilitating efficient cleaning and ensuring the stability of liquid replenishment in the wet preparation apparatus 100. During the cleaning process, the wastewater in the liquid storage chamber 41 can be discharged using the first pipe assembly, further improving cleaning efficiency and effectiveness. With this design, the liquid storage containers 4 can be automatically cleaned using the hot water storage container 16 and the second pipe assembly, and the wastewater discharged from the liquid storage chamber 41 can automatically unclog the first pipe assembly, eliminating the need for manual cleaning of the liquid storage containers 4 and manual unclogging of the first pipe assembly. This method saves cleaning time and greatly increases production capacity.

[0068] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0069] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
