Description

Technical Field

[0001] The present application relates to the technical field of tank liquid and potion analysis, and in particular to a tank liquid automatic analysis workstation. Background Art

[0002] In the field of wet process, especially in the PCB electroplating industry, precise control of solution composition is the key to ensure product quality. The chemical composition in the electroplating solution directly affects the quality characteristics of the electroplated layer, including adhesion, uniformity, hardness and corrosion resistance, and has a decisive influence on the stability and efficiency of the electroplating process. In order to ensure these characteristics, many PCB board factories and electroplating plants have to sample and analyze the solution of multiple process tanks on multiple production lines every day. However, the existing analysis methods mainly rely on manual sampling laboratory analysis or online analyzer analysis, both of which have obvious shortcomings.

[0003] On the one hand, the manual sampling and laboratory analysis method is labor-intensive, and workers need to move frequently to take samples, which not only easily causes work fatigue, but also makes the entire analysis process time-consuming, making it difficult to adjust the solution composition in time during production, affecting production efficiency. At the same time, errors in manual sampling and laboratory analysis may lead to inaccurate results. The high cost of professional equipment, instrument configuration and technical personnel requirements have pushed up operating costs, and laboratory resources usually only serve specific production lines, further reducing resource utilization and increasing the cost burden of enterprises.

[0004] On the other hand, although online analyzers can achieve real-time monitoring and avoid the uncertainty and delay problems caused by manual operation, their initial investment and operating costs are also high, including reagents, energy consumption and regular maintenance costs, and each production line is equipped with independent equipment, which leads to waste of resources. In addition, complex maintenance requirements and reliance on professional technicians also increase costs. When the production process changes, the online analyzer is not flexible enough and may need to be recalibrated or even replaced, which limits the flexibility and adaptability of the production line.

[0005] In view of the above problems, technicians in this field urgently need an analysis system that can not only accurately analyze the solution components, but also reduce costs and improve efficiency. To this end, a research and development plan for a tank liquid automatic analysis workstation is proposed. This workstation aims to provide an economical, efficient and easy-to-operate solution through technological innovation, which can meet the simultaneous analysis needs of multiple production lines, reduce human errors, improve production efficiency, and reduce the initial investment and long-term operating costs of enterprises, and enhance the flexibility and adaptability of production lines.

Record, data statistical analysis, is an automated intelligent workstation; the sampling module 100 includes a sample group 101 to be tested for carrying samples, and a sampling needle 102 for sampling samples, wherein the sample group 101 to be tested is arranged in the inner cavity of the sampling module 100. In order to detect multiple samples in the sample group 101 to be tested, a multi-axis mobile mechanical arm 105 is fastened with bolts on the left side of the inner cavity end of the chassis 700, and the surface of the sampling needle 102 is fixedly connected to the output end of the multi-axis mobile mechanical arm 105. The multi-axis mobile mechanical arm 105 is used to drive the sampling needle 102 to drive its position adjustment. The output end of the sampling needle 102 is connected to a sampling tube 103, and a sampling cleaning cup 107 is connected to the middle part of the sampling module 100 by bolts, wherein the sampling cleaning cup 107 is used to clean the inner and outer surfaces of the sampling needle 102 after sampling.

[0031] like Figure 5As shown in the figure, the analysis workstation mainly includes the following modules: The sampling module 100 is responsible for taking samples from the sample cup 1012 and pushing them to the sample distribution module 200 , and at the same time, the obtained QR code 1013 is uploaded to the software control and data traceability system 400 .

[0032] The sample distribution module 200 selects the corresponding analysis method according to the QR code 1013 obtained during sampling, and distributes it to the analysis module corresponding to the subsequent integrated analysis module through the software control and data traceability system 400.

[0033] The integrated analysis module includes a titration analysis module 2 310, a titration analysis module 320, a titration analysis module 4 330, a colorimetric analysis module 340 and an XRF analysis module 350. Multiple groups of analysis modules 360 can be flexibly configured and expanded according to the actual needs of the factory and the analysis method.

[0034] Software control and data traceability system 400: The software control and data traceability system 400 is responsible for the action and process control of each module, the selection and invocation of the analysis method, and the display, storage, query and traceability of the analysis result data; The sample group 101 to be tested includes a sample cup 1012 for storing a tank liquid sample, and there are multiple sample cups 1012. In order to store multiple sample cups 1012, a sample tray 1011 to be tested is arranged at the bottom of the sample cup 1012, wherein the sample cup 1012 is plugged into the storage tank cavity of the sample tray 1011 to be tested. At the same time, a QR code 1013 is pasted on the surface of the sample tray 1011 to be tested and on one side of the sample cup 1012, and a barcode scanner 104 is installed at the output end of the multi-axis mobile robot 105. The QR code 1013 is used in conjunction with the barcode scanner 104 to record and track data of the current tank liquid when analyzing the tank liquid in a single sample cup 1012. Before analyzing the tank liquid of the sample group 101 to be tested, the barcode scanner 104 is used to scan and record the relative QR code 1013 in advance; Specifically, the sample tray 1011 to be tested is made of corrosion-resistant material. Several sample cups 1012 can be placed in each sample tray 1011 to be tested. A QR code 1013 is provided at the corresponding position of each sample cup 1012. The analysis workstation can obtain relevant information of the tested sample by scanning the code with a barcode scanner 104, including the production process of the production line corresponding to the tested sample, thereby realizing the association between the tested sample and each production process; The inner cavity of the sampling and cleaning cup 107 is connected to a cleaning water pipe 108 and an air blowing pipe 109, wherein the input end of the cleaning water pipe 108 is connected to a sampling and cleaning pump 106, and the input end of the sampling and cleaning pump 106 is connected to an external pure water pipeline. Therefore, when the sampling and cleaning pump 106 is working, the pure water in the pure water pipeline can be pumped into the sampling and cleaning cup 107 through the sampling and cleaning pump 106 to clean the sampling needle 102 entering therein; Specifically, the input end of the air blowing tube 109 is connected to the air pump, and when the air pump is working, it can draw gas into the air blowing tube 109 to blow air on the surface of the sampling needle 102 to remove water stains on the surface; Furthermore, the working principle of the sampling module 100 is: Step 1: Place the sampling module 100 inside the chassis 700 Figure 6 The apparatus includes 4 sets of sample trays 1011 to be tested.

[0035] Step 2: The mobile multi-axis mobile robot 105 can realize movement in three directions of XYZ, and the moving range can cover all sample cups 1012 . The mobile multi-axis mobile robot 105 is equipped with a sampling needle 102 and a barcode scanning gun 104 .

[0036] Step 3: The barcode scanner 104 scans the QR code 1013 , and the sampling needle 102 descends to take samples from the corresponding sample tray 1011 to be tested, and transmits the samples to the sample distribution module 200 through the sampling tube 103 .

[0037] Step 4: After one sampling is completed, the sampling needle 102 rises above the liquid level of the sample cup 1012, and the sample remaining in the sampling needle 102 and the sampling tube 103 is evacuated and discharged.

[0038] Step 5: The multi-axis mobile robot 105 drives the sampling needle 102 to move to the sampling cleaning cup 107 position, and the sampling needle 102 descends and inserts into the sampling cleaning cup 107. The sampling cleaning pump 106 starts to discharge water from the cleaning water pipe 108 to spray and clean the outside of the sampling needle 102, and rinse the inside of the sampling tube 103 with pure water. After cleaning, the air pipe 109 blows air to remove the water on the outer surface of the sampling needle 102.

[0039] Step 6: Repeat steps 3-5 to sample the sample cup 1012 in sequence; The sample distribution module 200 includes a sampling pump 201, a sampling and distribution switching valve 202, a standard liquid barrel 203, a pure water barrel 204 and a waste water barrel 205, wherein the pure water barrel 204 and the waste water barrel 205 are located at the bottom of the inner cavity of the chassis 700, and the sampling pump 201 is arranged in the inner cavity of the chassis 700, wherein the sampling pump 201 and the sampling and distribution switching valve 202 are bidirectionally connected through a pipeline, and the surface of the sampling and distribution switching valve 202 is connected with a plurality of communication ports, such as Figure 8As shown, the multiple communication ports are: communication port 1, communication port 2, communication port 3, communication port 4, communication port 5, communication port 6, communication port 7, communication port 8, communication port 9, communication port 10, communication port 11, and communication port 12, wherein communication port 8 and communication port 9 are two spare ports.

The purpose of this step is to rinse the sampling pump 201 and the sampling pipeline to ensure the purity of the sample extracted in step 4; Step 4: After rinsing is completed, the sampling and distribution switching valve 202 is switched to the connection port 1, and the precisely quantified sample is extracted from the sample distribution module 200 to the inside of the sampling pump 201, and the sampling and distribution switching valve 202 is switched to the connection port 2, and the precisely quantified sample is injected into the titration analysis module A; Step 5: Sampling and distributing the switching valve 202 to the connecting port 11, extracting pure water into the sampling pump 201, sampling and distributing the switching valve 202 to the connecting port 2, and pumping the pure water into the titration analysis module 1 300.
