Description

Technical Field

[0001] The present application relates to the field of automated testing equipment, and in particular to an automated testing device and method. Background Art

[0002] During the PBC board manufacturing process, a variety of chemical fluids are used throughout the production line, such as acidic copper chloride solution and alkaline copper chloride solution. These chemical fluids are crucial to ensuring product quality, so their composition needs to be regularly monitored and adjusted.

[0003] To ensure the quality of chemical solutions, existing techniques typically rely on manual testing of the solution in a beaker. Specifically, the test liquid is added to the beaker, and a specific reagent is added dropwise, while stirring thoroughly with a manual stirrer. Technicians then visually observe parameters such as color change and reaction time after the addition to determine if the solution meets the standards. After each test, the stirrer must be cleaned to prevent contamination of the next batch of test solution.

[0004] Regarding the aforementioned related technologies, the applicant believes they suffer from the following drawbacks: First, manual operation is susceptible to subjective factors, resulting in inaccurate test results; second, frequent manual operation is not only time-consuming and labor-intensive, but also increases the risk of human error. Especially when processing large numbers of samples, manual testing speeds cannot meet the requirements of efficient production. Furthermore, long-term exposure to chemicals poses potential health risks to humans. Therefore, developing a device that can automate the testing process is particularly important. Summary of the Invention

[0005] In order to improve the efficiency and accuracy of testing, the present application provides an automated testing device and method.

[0006] The present application provides an automated testing device and method using the following technical solutions: An automated testing device, comprising: A test bench, wherein a working chamber is provided on the surface of the test bench, and the working chamber is provided with a test area; A slide, the slide surface is used to place beakers containing the solution to be tested and empty beakers, the slide is connected to the surface of the test table for transverse sliding, and the test table is provided with a translation drive member, the translation drive member is used to drive the slide to drive the beakers containing the solution to be tested and the empty beakers to enter and exit the test area in sequence; Several liquid supply assemblies, each of which stores a reaction solvent required for the test. One of the liquid supply assemblies stores pure water. The liquid supply assemblies are used to drop the corresponding reaction solvent into a beaker containing a solution to be tested in the test area, and to inject pure water into an empty beaker; A stirring mechanism, located in the assay area and used to stir the solution in the beaker, and the stirring mechanism can be raised and lowered; A visual system, wherein the visual system is used to capture the changes of the solution in the beaker in real time; When conducting an assay, the translation drive member drives the slide to move, so as to move a beaker containing a solution to be tested into the assay area. The stirring mechanism extends downward into the beaker, and the plurality of liquid supply assemblies inject the reaction solvent required for the assay into the beaker below for the assay. The stirring mechanism stirs the solution in the beaker, and the camera group captures the changes in the solution in the beaker in real time. After the test is completed, the translation drive member drives the slide to move to move the empty beaker into the test area, the stirring mechanism extends downward into the beaker, the liquid supply component injects pure water into the beaker below, and the stirring mechanism stirs the pure water in the beaker to clean the stirring mechanism.

[0007] By adopting the above technical solution, the automated testing method uses a slide and translation drive to automatically move beakers containing the test solution and empty beakers in and out of the testing area, ensuring operational consistency before and after each test and improving the standardization and accuracy of the testing process. The automatic lifting design of the stirring mechanism ensures more uniform stirring, while the visual system monitors solution changes in real time to ensure the reliability and timeliness of test results. In addition, after the test is completed, the system can automatically inject purified water into the empty beaker and clean the stirring mechanism, effectively preventing cross-contamination and extending the service life of the equipment. The entire process requires no human intervention, significantly improving the efficiency and safety of the test.

[0008] Preferably, the liquid supply assembly includes a liquid storage tank, a pump body connected to the liquid storage tank, and a dripper connected to the output end of the pump body. The liquid storage tank is located inside the working chamber, and the dripper extends to the testing area and is arranged vertically downward.

[0009] By adopting the above technical solution, the combined design of the liquid storage tank, pump body and dripper allows various test solutions to be accurately dripped into the beaker. The liquid storage tank is located inside the working chamber, ensuring the safe storage of the solution and preventing the external environment from contaminating the solution. When the test is required, the pump body extracts the solution from the liquid storage tank and transports it to the dripper through a pipe, and finally drips vertically into the beaker, achieving precise control of the amount of solution required for the test. This design not only improves the accuracy and reliability of the test, but also reduces human intervention and improves work efficiency. In addition, since the dripper is set vertically downward, it can effectively prevent the solution from splashing or overflowing, further ensuring the cleanliness and safety of the experimental environment.

[0010] Preferably, each of the drippers is connected to the corresponding pump body via a pipeline, and a control valve is provided on the pipeline for controlling the flow rate of the solution.

[0011] By employing this technical solution, precise control of different test solutions is achieved. Specifically, a control valve is installed in the pipeline between each dripper and the corresponding pump body, which can accurately adjust the flow rate of the solution delivered by each liquid supply component, ensuring a consistent amount of solution for each test, improving the accuracy and reliability of the test. In addition, this design facilitates maintenance and replacement, increasing the stability and service life of the equipment.

[0012] Preferably, the test area is vertically slidably connected to a slide and is provided with a lifting drive member for driving the slide to move up and down, and the drippers of the liquid supply components are fixed on the slide.

[0013] By adopting the above technical solution, the height position of each dripper can be accurately controlled through the design of the slide and the lifting drive, thereby ensuring that the optimal position is reached each time the reagent is added, reducing the error caused by different heights of the drippers; the vertical sliding design of the slide allows multiple liquid supply components to flexibly adjust the position of the dripper according to actual needs, adapt to different types of laboratory requirements, and improve the applicability of the equipment; the automated lifting drive replaces the manual adjustment of the dripper height operation, reduces manual intervention, reduces the difficulty of operation, and improves work efficiency; when the stirring mechanism needs to be cleaned, the dripper can be moved to the appropriate position through the lifting drive, which facilitates the injection of pure water and the thorough cleaning of the stirring mechanism to avoid cross contamination.

[0014] Preferably, the stirring mechanism includes a stirring paddle rotatably connected to the slide and arranged vertically, and a stirring driving member arranged on the slide and used for rotating the stirring paddle.

[0015] By adopting this technical solution, the stirring paddle can automatically rotate under the action of the stirring drive, thereby evenly and effectively stirring the solution in the beaker, improving the accuracy and consistency of the test. At the same time, the position of the stirring mechanism can be adjusted as the slide moves up and down, making the stirring process more flexible and controllable, further improving the efficiency and reliability of the test.

[0016] Preferably, a pH detection rod is vertically arranged at the slide seat, and the pH detection rod is used to detect the pH value of the solution.

[0017] By adopting this technical solution, a vertical pH probe mounted on the slide can monitor the pH changes of the solution in the beaker in real time and provide timely feedback to the control system, allowing for more precise control of various parameters during the test. This allows for quick and accurate information on the solution's pH at different stages of the test, helping to improve the accuracy of test results.

[0018] Preferably, a horizontally arranged sliding rod is provided on the surface of the test table, the sliding rod passes through the test area, the slide is slidably connected to the sliding rod, and the translation drive is used to drive the slide to slide along the extension direction of the sliding rod.

[0019] By adopting this technical solution, the slide, guided by the slide rod, can move smoothly and precisely along the predetermined path, ensuring that the beaker reaches the exact position in the testing area during each test. This not only improves the operating stability and reliability of the equipment, but also effectively avoids test errors caused by positional deviation. Furthermore, the translational drive makes the entire movement process smoother and more controllable, further improving the efficiency and accuracy of the test.

[0020] An automated testing method, using an automated testing device, comprises the following steps: S1: A beaker containing the test solution and an empty beaker are placed on a slide. The translation drive is activated to move the slide until the beaker containing the test solution is moved into the testing area. The stirring mechanism extends downward into the beaker. Several liquid supply components inject the reaction solvent into the beaker below for testing. The stirring mechanism stirs the solution in the beaker, and the camera team records the changes in the solution in the beaker in real time. S2: After the test is completed, the stirring mechanism moves away from the beaker, and the translation drive member drives the slide to move to move the empty beaker into the test area. The stirring mechanism extends downward into the beaker, and the liquid supply assembly storing purified water injects purified water into the beaker below. The stirring mechanism stirs the purified water in the beaker to clean the stirring mechanism. S3: After the stirring mechanism is cleaned, the stirring mechanism moves upward to reset, and the slide moves and resets under the drive of the translation drive member, and the two beakers on the slide are moved out of the test area.

[0021] By adopting this technical solution, the automated testing method utilizes a slide and translational drive to automatically move beakers in and out of the testing area, ensuring operational consistency before and after each test, and improving the standardization and accuracy of the testing process. The automatic lifting design of the stirring mechanism ensures more uniform stirring, while the visual system monitors solution changes in real time to ensure the reliability and timeliness of test results. Furthermore, after the test is completed, the system automatically injects purified water into another beaker and cleans the stirring mechanism, effectively preventing cross-contamination and extending the service life of the equipment. The entire process requires no human intervention, significantly improving testing efficiency and safety.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The automated slide and translation drive enable precise positioning and rapid replacement of beakers, significantly improving test speed and work efficiency while reducing errors and risks caused by manual operation. 2. Using the liquid supply component to accurately add different test solutions and combining it with a visual system to monitor solution changes in real time, the accuracy and reliability of test results are effectively improved, avoiding subjective bias in manual judgment. 3. A special cleaning process has been designed to ensure that the equipment is clean and pollution-free before and after each test through pure water flushing and the self-cleaning function of the stirring mechanism, preventing cross contamination and ensuring the accuracy of subsequent tests.

[0027] The following is combined with Figure 1-4 This application is described in further detail.

[0028] The present application discloses an automated testing device and method. Figure 1 and Figure 2 The system comprises a test bench 1, a slide 3, a stirring mechanism, a visual system 5, and several liquid supply components. A work chamber 12 is mounted on the surface of the test bench 1, and an assay area 13 is located in front of the work chamber 12 for automated assays. The slide 3 is used to hold beakers 2 containing test solutions and empty beakers 2, and is connected to the surface of the test bench 1 by sliding horizontally. A translational drive 4 is mounted on the test bench 1, which drives the slide 3 to move the two beakers 2 in and out of the assay area 13.

[0029] Reference Figure 1 and Figure 3, two grooves 31 are provided on the slide 3 for placing the corresponding beakers 2. A horizontally arranged slide bar 11 is installed on the surface of the test bench 1, and the transverse slide bar 11 runs through the bottom of the test area 13. Among them, the slide 3 is slidably connected to the slide bar 11, and the translation drive 4 is used to drive the slide 3 to slide along the extension direction of the slide bar 11. The slide 3 is connected to the test bench 1 through the slide bar 11 to ensure that the slide 3 moves smoothly and reliably. The translation drive 4 can be an electric push rod, a cylinder or a screw transmission mechanism, and its function is to push the slide 3 to move back and forth along the linear guide rail, so that the beaker 2 can enter inside and outside the test area 13.

[0030] Reference Figure 2 and Figure 4 In this embodiment, the liquid supply assembly includes a liquid storage tank, a pump body 121 and a dripper 135. Each liquid storage tank stores a specific reaction solvent, and one of the liquid storage tanks is specifically used to store pure water. The liquid storage tank can be made of polyethylene or glass, which has good chemical stability and transparency, making it easy to observe the liquid level. The pump body 121 is responsible for transporting the solution in the liquid storage tank to the dripper 135. A peristaltic pump or a diaphragm pump can be selected. Both pumps can accurately control the flow rate and will not contaminate the liquid. The dripper 135 extends above the test area 13 and is arranged vertically downward to ensure that the solution can be accurately dripped into the beaker 2. The dripper 135 is connected to the pump body 121 by a pipe, and a control valve is provided on the pipe to control the flow rate of the solution.

[0031] In this embodiment, the liquid storage tank and the pump body 121 are both installed inside the working chamber 12. The test area 13 of the working chamber 12 is vertically slidably connected to a slide 131 and a lifting drive 134 for driving the slide 131 to move up and down. The lifting drive assembly can adopt a vertical linear module or a vertical screw transmission mechanism. Several drippers 135 and a stirring mechanism are all installed and fixed on the slide 131. The drippers 135 are connected to the corresponding pump body 121 through a pipe. The pipe is provided with a control valve for regulating the flow of the solution. The stirring mechanism includes a stirring paddle 133 and a stirring drive 132. The stirring paddle 133 is rotatably connected to the slide 131 and is vertically arranged, and can stir the solution by rotating. The stirring paddle 133 can be made of stainless steel, which is both corrosion-resistant and not easy to rust. The stirring drive 132 can be a small motor connected to the stirring paddle 133 through a coupling, driving the stirring paddle 133 to rotate at high speed. In order to prevent the stirring paddle 133 from colliding with the wall of the beaker 2, a buffer washer can be provided at the bottom of the stirring paddle 133.

[0032] The interior of the working chamber 12 is separated from the testing area 13 by transparent glass, allowing the visual system 5 to capture real-time changes in the solution within the beaker 2. The visual system 5 comprises a high-definition camera, an image processor, and a data transmission module. The high-definition camera is installed within the working chamber 12 and faces the testing area 13 through the transparent glass, where the beaker 2 is positioned. The camera features automatic focus and light compensation, enabling it to clearly capture important information such as color changes and reaction time, even in low-light environments. The image processor receives image data captured by the camera and preprocesses it to extract key features. The data transmission module transmits the processed data to the main control system, which generates control instructions based on the received data to regulate the operating states of the liquid supply assembly, stirring mechanism, and translational drive 4. Specifically, the visual system 5 uses an image recognition algorithm to detect color changes in the solution and determine the extent of the chemical reaction based on changes in grayscale value and color contrast. Furthermore, an edge detection algorithm can be used to determine the turbidity of the solution, and a timer can be used to measure the reaction time. Combined, these data provide a comprehensive picture of the solution's state changes.

[0033] A pH detection rod 136 is vertically fixed to the slide 131. This rod is used to detect the pH value of the solution. The pH detection rod 136 is a common electrode-type sensor. The vertical pH detection rod 136, mounted on the slide 131, can monitor the pH changes of the solution in the beaker 2 in real time and provide timely feedback to the control system for more precise control of various parameters during the test. This allows for quick and accurate acquisition of the solution's pH information at different stages of the test, helping to improve the accuracy of the test results.

[0034] The present application also discloses an automated testing method, which uses the automated testing device described above and includes the following steps: S1: When conducting the test, a beaker 2 containing the solution to be tested and an empty beaker 2 are placed on the slide 3 respectively, and the translation drive 4 is started to drive the slide 3 to move until the beaker 2 containing the solution to be tested is moved into the test area 13. The stirring mechanism extends downward into the beaker 2, and several liquid supply components drip the reaction solvent into the beaker 2 in turn. The stirring mechanism starts to run and fully stirs the solution in the beaker 2. At the same time, the visual system 5 records the color changes and other parameters during the entire test process in real time for subsequent analysis. The data processing unit generates control instructions based on the acquired information, adjusts the dripping amount and speed of the liquid supply component, as well as the speed and stirring time of the stirring mechanism, to ensure the accuracy and consistency of the test process.

[0035] S2: After the test is completed, the stirring mechanism rises and leaves the completed beaker 2. The translational drive 4 again drives the slide 3 to move the empty beaker 2 into the testing area 13. At this point, the liquid supply assembly, which stores purified water, begins to operate, injecting purified water into the empty beaker 2. The stirring mechanism descends and starts again, stirring the purified water to thoroughly clean the stirring paddle 133 and other residual solution. This not only ensures the accuracy of the next test process but also extends the service life of the equipment.

[0036] S3: After the stirring mechanism is cleaned, the stirring mechanism moves upward to reset, and the slide 3 moves and resets under the drive of the translation drive 4, and the two beakers 2 on the slide 3 are moved out of the test area 13.

[0037] The implementation principle of this embodiment is as follows: through an integrated automated testing device, the entire process, from sample preparation, reagent addition, stirring and mixing to data collection, is automated. Compared with traditional manual testing methods, this device not only improves work efficiency and reduces human error, but also greatly reduces the risk of workers being exposed to hazardous chemicals for a long time. Especially in large-scale production environments, the application of this device can significantly improve product quality and production efficiency, bringing greater economic and social benefits to enterprises. At the same time, by introducing a visual system 5 and a data processing unit, real-time monitoring and intelligent control of the testing process are achieved, further improving the accuracy and reliability of the test.

[0038] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
