Description

Technical Field

[0001] The invention relates to the field of photovoltaic preparation, and in particular to an intelligent monitoring system and method for segmented processing and preparation of silver-coated copper powder. Background Art

[0002] As the global economy develops rapidly, energy consumption is also increasing. Renewable energy is increasingly valued by countries around the world. Photovoltaic power generation has become a clean, low-carbon, and price-competitive energy form in many countries. The introduction of the photovoltaic industry chain and N-type batteries Direct photoelectric conversion uses the photovoltaic effect of semiconductors. When silicon wafers are exposed to light, the charge distribution changes to generate electromotive force, converting photons into electrons and light energy into electrical energy. The industrial chain with the application and development of silicon materials as its content is the photovoltaic industry;

[0003] Photovoltaic silver paste is a basic material with silver powder as the main raw material. Due to the high price of metallic silver and the high process requirements of silver powder, there are difficulties in preparation. The cost reduction of silver paste materials lies in achieving large-scale production and localization. Silver-coated copper powder is developed to replace silver powder to achieve cost reduction. Copper has good electrical and thermal conductivity and is low in price. Compared with silver, it has a huge price advantage;

[0004] Since the smaller the particle size of copper powder, the greater its surface activity and the easier it is to oxidize, if you do not use freshly made copper powder for silver coating, you must pre-treat the copper powder before coating. Currently, the pre-treatment of copper powder is generally soaked in dilute sulfuric acid to remove the surface oxide, then washed with distilled water until there is no Cu+ detected by potassium hexahydroferrate, and then coated with silver.

[0005] In addition, when copper powder is surface-modified with an organic solvent, it is necessary to wash the copper powder. For example, the copper powder is added to an acetone solution to completely wet the copper powder, and then a certain amount of water is added to dilute the acetone. The solution is placed in a ventilated place for a period of time, and silver plating can be performed after the acetone is completely evaporated.

[0006] Coating a layer of metallic silver on the surface of copper powder can improve the oxidation resistance, conductivity and many other physical properties of copper powder, making it have many excellent properties of silver powder. Compared with single silver powder, the production cost of this copper-silver bimetallic powder is much lower, so it has broad application prospects. Conductive coating is a functional coating that has developed rapidly in recent years. It gives objects conductivity and can be widely used in electronics, construction, aviation, military and other fields. Silver-coated copper powder has good conductivity, making it a good conductive filler.

[0007] At present, in the preparation process of silver-coated copper powder, each process of copper powder silver plating can only be operated independently, and each silver plating process is manually operated and monitored, which has low intelligence. In addition, it is impossible to accurately add the reducing agent to the copper powder during the copper powder silver plating reaction. It can only be manually judged according to the important data of the copper powder input, or the reducing agent solution can be added according to the set threshold range, but the measurement of the reducing solution cannot be accurately determined. Too little addition may lead to incomplete silver layer coating, or excessive addition of reducing agent may lead to waste and loss, affecting the silver plating of copper powder. The present application aims to automatically monitor the segmented processing of silver-coated copper powder, automatically detect and intelligently execute control of the copper powder silver plating process, and accurately add the reducing solution after automatic weighing of the copper powder, and further monitor the subsequent silver-coated copper powder to improve the intelligence and efficiency of copper powder silver plating.

[0047] The solution cleaning pretreatment module is used to monitor the multi-level copper powder and put it into the cleaning solution in multiple proportions for cleaning, so as to pretreat the copper powder;

[0048] Further explanation is needed. The solution cleaning pretreatment module includes a copper powder multi-level component weighing and scanning submodule and a cleaning solution proportion on-demand dosing submodule. The copper powder multi-level component weighing and scanning submodule includes a weighing sensor and a scanner. The weighing sensor is electrically connected to the scanner. The weighing sensor is used to weigh the copper powders that are sequentially put into the stirring tank for solution cleaning one by one. The data weighed by the weighing sensor is scanned and summarized according to the scanner, and the summarized copper powder weighing data is sent to the cleaning solution proportion on-demand dosing submodule. The cleaning solution proportion on-demand dosing submodule intelligently doses the cleaning solution to clean the copper powder according to the proportion based on the copper powder weighing data scanned and summarized by the scanner, and sends the metered and weighing data of the administered cleaning solution to the central control module in real time for verification and backup.

[0049] The chemical silver plating mass ratio monitoring module is used to detect and proportion the type of reducing solution, analyze the mass ratio of copper powder to reducing solution, and perform chemical silver plating on the copper powder through ultrasonic stirring;

[0050] It also needs to be further explained that the chemical silver plating mass ratio monitoring module includes a reducing solution classification and addition monitoring ratio submodule and a silver plating ultrasonic stirring control reaction submodule. The reducing solution classification and addition monitoring ratio submodule is used to perform ratio detection on the reducing solution that needs to be classified and added to the cleaned copper powder, obtain the copper powder weighing data, and perform corresponding analysis according to the weighing data based on the set reducing solution ratio threshold range. The reducing solution ratio concentration obtained by the analysis is added into the stirring tank. The silver plating ultrasonic stirring control reaction submodule is used to control the stirring tank to stir the reducing solution and copper powder for silver plating, and monitor the silver plating mixing reaction of the copper powder.

[0051] Among them, the reduction solution classification addition monitoring ratio submodule includes a liquid level sensor, which detects the volume of the copper powder solution inside the stirring tank. According to the weighed copper powder data, the addition amount of different types of reduction solutions to be added is analyzed, and the addition of a certain type of reduction solution is set as Bn. When the weight of the copper powder data corresponds to the addition amount of the reduction solution Bn, the addition amount threshold range of the reduction solution Bn to be added is set to N Bn ~N Bn+1 , the threshold range of the corresponding amount of reducing solution Bn to be added is subdivided into several threshold segments N Bn ~N a 、N a ~N b ,...,N z ~N Bn+1 , set the midpoint addition amount of several threshold segments to Analyze the concentration of the stirred copper powder solution with different addition amounts of a certain reducing solution within the corresponding addition amount threshold range, and set the configuration concentration of the copper powder solution after adding the reducing solution as C Bn , according to the formula;

The weighing sensor obtains the weight of the filtered silver-coated copper powder and sends it to the central control module. At the same time, the weighing summary data of the copper powder put into the mixing tank is obtained for comparison and analysis. When the filtered silver-coated copper powder solid matter is less than the set threshold, the silver-coated copper powder solution needs to be introduced into the filtration equipment for repeated separation and filtration until the silver-coated copper powder filtered out by the weighing sensor is greater than the set threshold. The separated silver-coated copper powder quality cleaning pH value detection submodule is used to detect the pH value of the silver-coated copper powder after washing with distilled water after the filtration is completed, to ensure that the silver-coated copper powder is washed to neutral with distilled water;

When the filtered silver-coated copper powder solids are less than the set threshold, the silver-coated copper powder solution needs to be introduced into the filtration equipment for repeated separation and filtration until the silver-coated copper powder filtered out by the weighing sensor is greater than the set threshold.

[0075] It is also necessary to explain in detail: In S3, the filtered silver-coated copper powder solids are weighed by the weighing sensor inside the filtered liquid copper powder solids analysis and detection submodule, and the weight of the filtered silver-coated copper powder is sent to the central control module. At the same time, the weighing summary data of the copper powder put into the mixing tank is obtained for comparison and analysis.
