Abstract
Description
Technical Field
[0001] This utility model relates to the field of water quality testing technology, specifically to an automatic surface water testing device. Background Technology
[0002] Surface water refers to all dynamic and static water on the land surface, also known as "terrestrial water." It includes various liquid and solid water bodies, mainly rivers, lakes, swamps, glaciers, and ice caps. It is one of the important sources of our drinking water; therefore, it is necessary to regularly monitor the pollution status of surface water to ensure water safety.
[0003] However, current water quality testing laboratories rely on a combination of manual labor and instruments, resulting in low automation. Different tests are typically handled by different technicians, who perform the entire process from pretreatment and testing to reporting. This necessitates collecting multiple parallel water samples to meet testing requirements. Furthermore, the pretreatment work for different tests is often identical. Assigning the same water sample to different technicians leads to duplication of work and increases their workload. During the reporting phase, technicians are generally only responsible for reporting on their assigned test. To obtain the overall test results, it is necessary to compile the reports from all technicians, making result retrieval inconvenient and reducing testing efficiency. Utility Model Content

[0045] Example 1:
[0046] Please refer to Figure 1-5 This embodiment provides an automatic surface water detection device, mainly used for environmental pollution detection of surface water and detection of factory wastewater discharge. It includes a liquid separation module 10, a loading and unloading module 20, a liquid addition module 30, a spectrophotometric detection module 40, a settling module 50, a digestion module 60, and a collaborative robot 70.
[0047] The liquid separation module 10 has a sample inlet and a first docking station. The liquid separation module 10 is used to receive and separate the test liquid. The test liquid is generally sealed in a sample delivery bottle and sent into the local surface water automatic detection device through the sample inlet. The sample delivery bottle has a capacity of 1000 mL or other specifications. The first docking station is used to dock with the collaborative robot 70, meaning the collaborative robot 70 can retrieve or deliver the test liquid to the liquid separation module 10 through the first docking station.
[0048] The loading / unloading module 20 has an inlet and a second docking station. The loading / unloading module 20 is connected to the dispensing module 10 and is used to provide containers required for testing. These containers are generally arranged in trays, with dispensing bottles or test tubes loaded on the trays. The dispensing bottles have a capacity of 150mL or other specifications. The dispensing bottles or test tubes on the trays are arranged in a 3*4 layout, i.e., 3 bottles per row, for a total of 4 rows, or a 3*5 layout. The second docking station is used to dock with the collaborative robot 70. The collaborative robot 70 can retrieve or deliver the test liquid to the loading / unloading module 20 through the second docking station.
[0049] The liquid addition module 30 has a third docking station, which is used to add reaction liquid to the liquid to be tested. The third docking station is used to dock with the collaborative robot 70, and the collaborative robot 70 can take out or send the liquid to be tested to the liquid addition module 30 through the third docking station.
[0050] The spectrophotometric detection module 40 has a fourth docking station. The spectrophotometric detection module 40 is used to detect the absorption of ultraviolet light and visible light by the test liquid, thereby analyzing the properties of the test liquid. The fourth docking station is used to dock with the collaborative robot 70. The collaborative robot 70 can take out or send the test liquid to the spectrophotometric detection module 40 through the fourth docking station.
[0051] The settling module 50 has a fifth docking station and a settling rack for placing the test liquid. The fifth docking station is used to dock with the collaborative robot 70. The collaborative robot 70 can take out or put the test liquid into the settling module 50 through the fifth docking station.
[0052] The digestion module 60 has a sixth docking station, which is used to perform high-temperature treatment on the test liquid. The sixth docking station is used to dock with the collaborative robot 70, through which the collaborative robot 70 can take out or send the test liquid to the digestion module 60.
[0053] The collaborative robot 70 includes a robotic arm 71, which may be a six-axis robotic arm 71, giving it flexible degrees of freedom. The robotic arm 71 has an operating end 711, which is used to grasp and place the test liquid. The collaborative robot 70 is used to transfer the test liquid between the first docking station, the second docking station, the third docking station, the fourth docking station, the fifth docking station, and the sixth docking station. In this embodiment, the test liquid flows within the local surface water automatic detection device. It can be transferred using a dispensing bottle as a carrier and a tray as a unit. The robotic arm 71 moves the operating end 711 to one of the first, second, third, fourth, fifth, or sixth docking stations. The operating end 711 then connects to the tray to grasp the test liquid. Subsequently, the robotic arm 71 moves the operating end 711 to the same station, separating it from the tray to place the test liquid. This allows the test liquid to flow between the dispensing module 10, the loading / unloading module 20, the liquid addition module 30, the spectrophotometric detection module 40, the settling module 50, and the digestion module 60, enabling the detection of various indicators of the test liquid, improving detection efficiency, ensuring high consistency of the test liquid, and providing reliable data.
[0054] The first, second, third, fourth, fifth, and sixth docking stations are all positioned facing the collaborative robot 70. Furthermore, the first, second, third, fourth, fifth, and sixth docking stations are arranged in a U-shape around the collaborative robot 70.
[0055] The collaborative robot 70 is also equipped with a ground rail 80 at its bottom, on which a mounting base 81 is slidably connected. The liquid addition module 30, the spectrophotometric detection module 40, the settling module 50, and the digestion module 60 are respectively positioned near both sides of the ground rail 80. The liquid separation module 10 and the loading / unloading module 20 are positioned near the end of the ground rail 80. The collaborative robot 70 is fixed to the mounting base 81, allowing it to move back and forth along the length of the ground rail 80. This positions the collaborative robot 70 within a U-shaped opening, and the ground rail 80 is parallel to the two U-shaped walls, allowing the robot to move at any position on the ground rail 80 for easy loading and unloading of the test liquid.
[0056] With a U-shaped layout, each detection module is set up in a U-shape. The collaborative robot 70 is mounted on a ground rail 80, which is located in the middle of the U-shape. The collaborative robot 70 can move back and forth in the middle of the U-shape via the ground rail 80. This design can solve the defect of insufficient arm span of the collaborative robot 70 in the circular layout, saving costs and space. As the number of detection modules increases, it can also be changed to an elliptical layout. At the same time, the collaborative robot 70 can move freely and move to the corresponding position to assist in the loading or transport of samples according to the needs of each detection process, improving the flexibility of the collaborative robot 70.
[0057] In some other preferred embodiments, the first docking station, the second docking station, the third docking station, the fourth docking station, the fifth docking station and the sixth docking station are arranged in a ring around the circumference of the collaborative robot 70, such as a circular layout, with the collaborative robot 70 located at the center of the circular or elliptical layout.
[0058] Furthermore, the liquid dispensing module 10 is provided with a first slide rail at its bottom, which moves the liquid dispensing module 10 closer to or further away from the collaborative robot 70; the loading and unloading module 20 is provided with a second slide rail at its bottom, which moves the loading and unloading module 20 closer to or further away from the collaborative robot 70; the liquid adding module 30 is provided with a third slide rail at its bottom, which moves the liquid adding module 30 closer to or further away from the collaborative robot 70; the spectrophotometer detection module 40 is provided with a fourth slide rail at its bottom, which moves the spectrophotometer detection module 40 closer to or further away from the collaborative robot 70; the settling module 50 is provided with a fifth slide rail at its bottom, which moves the settling module 50 closer to or further away from the collaborative robot 70; and the digestion module 60 is provided with a sixth slide rail at its bottom, which moves the digestion module 60 closer to or further away from the collaborative robot 70.
[0059] With a circular layout centered on the collaborative robot 70, each detection module is arranged around the collaborative robot 70 and mounted on a slide rail. The slide rail can move each module away from or towards the collaborative robot 70. This design not only saves space, but also allows the entire sample transfer to be completed with just one collaborative robot 70, thus saving costs.
[0060] In this embodiment, the liquid separation module 10 and the loading / unloading module 20 are mainly used for tray loading / unloading of the test liquid, shaking the original sample bottle and opening the cap. After the cap is opened, the tray is transported to the liquid separation station to quantitatively aspirate a portion of the test liquid into a clean test tube. The liquid separation module 10 and the loading / unloading module 20 have automatic cleaning functions, automatic waste liquid discharge, and at the same time, pH value testing of the original sample is performed.
[0061] Specifically, the liquid separation module 10 includes a liquid separation station equipped with a cap opening mechanism, a liquid suction mechanism, a raw liquid receiving mechanism, and a pH value detection mechanism. The cap opening mechanism is used to open the cap of the feeding bottle containing the liquid to be tested. The raw liquid receiving mechanism is used to fix the container for testing, and a tray sensor is provided at the bottom of the raw liquid receiving mechanism. The liquid suction mechanism includes a suction head, a metering pump, and a transfer assembly. The suction mechanism is used to quantitatively suck up the liquid to be tested from the feeding bottle and transfer it to the container for testing. The pH value detection mechanism is used to test the pH value of the test liquid. The loading and unloading module 20 is equipped with an automatic draining mechanism and an automatic cleaning mechanism. The automatic draining mechanism is used to drain the liquid remaining in the pipeline during liquid separation, and the automatic cleaning mechanism is used to clean the pipeline of the liquid separation module.
[0062] During use, the test liquid stock solution placed on the tray is manually pushed into the dispensing module 10. Before dispensing, the cap needs to be unscrewed using the cap opening mechanism and then stored in the cap storage rack inside the dispensing module 10. The cap storage rack has two layers with varying heights. After the cap is unscrewed, the test liquid stock solution is transferred to the dispensing station by a transfer component that can move left, right, up, and down. Above the dispensing station is a suction head that can move up, down, left, right, forward, and backward. Before suction, a clean bottle for holding the test liquid stock solution needs to be placed on the tray, and then the tray is pushed into the stock solution receiving mechanism. The moving component on the stock solution receiving mechanism moves the tray and empty container to the dispensing station. At this time, the suction mechanism on the dispensing station can operate to suction the test liquid stock solution into the empty container, and at the same time, the pH value of the test liquid stock solution is tested. In this embodiment, the aspiration head is connected to a metering pump. The transfer assembly controls the aspiration head to be immersed in the sample bottle. The metering pump accurately draws the test liquid into the testing container. Usually, the test liquid needs to be drawn into multiple test tubes for multiple sets of tests to improve the accuracy of experimental data. The amount of sample taken depends on the characteristics of different samples.
[0063] The liquid addition module in this embodiment has an automatic shaking mechanism, is compatible with 30 different liquids, and automatically selects the liquid addition amount quantitatively. It reacts chemically with the test liquid by adding the reaction solution.
[0064] Specifically, the liquid addition module 30 has a liquid addition station, which is equipped with a liquid addition platform, an automatic shaking mechanism, and a liquid level control device. The automatic shaking mechanism drives the liquid addition platform to shake along a preset trajectory, and the liquid level control device is used to control the amount of reaction liquid added.
[0065] The liquid addition described in this embodiment involves adding a reaction solution (such as sulfuric acid or hydrochloric acid) based on the characteristics of the sample to be tested. This reaction solution can chemically react with the sample. After the liquid is added, the liquid addition station moves left, right, up, and down under the drive of an automatic shaking mechanism, simulating human shaking of the liquid to ensure uniform mixing and a more complete reaction. A wastewater collection tank is located below the liquid addition station to collect any water overflowing during the shaking process. Manual replenishment of the reaction solution is required when it runs out. Simultaneously, the liquid level control device integrates a high-precision liquid level sensor, enabling precise volumetric liquid addition and accurate control of the amount of reaction solution added.
[0066] The digestion module 60 in this embodiment digests the test liquid by means of high temperature. The digestion module 60 has the functions of automatic opening of the lid, automatic digestion and venting, automatic water addition, and temperature and pressure can be monitored.
[0067] Specifically, the digestion module 60 has a heating station and a cooling station. The heating station is equipped with a heating mechanism for high-temperature treatment of the test liquid, and the cooling station is equipped with a cooling mechanism for cooling the test liquid. The digestion module 60 also has an automatic cap-opening and closing mechanism for providing a cap to close the testing container and / or opening the cap of the testing volume. The automatic cap-opening and closing mechanism can also be located at the operating end 711 of the collaborative robot 70, allowing the collaborative robot 70 to handle the cap-opening and closing processes required by each module. Those skilled in the art can implement this according to actual needs.
[0068] The digestion process described in this embodiment involves using chemical reactions to break down organic matter and dissolve particulate matter, converting the analyte into a single high-valence state or an easily decomposed inorganic compound. During operation, the collaborative robot 70 first delivers the test solution to the digestion station. Then, an automatic cap-opening and closing mechanism automatically closes the cap. At this point, the cap is not yet locked. The collaborative robot 70 then tightens the cap using a mechanism that assists the heating device in sealing the cap. After heating is complete, the collaborative robot 70 transfers the test solution to a cooling station for cooling, or transfers it to a settling module 50 for cooling.
[0069] The settling module 50 is equipped with multiple sets of settling racks; these racks are used to hold the test liquid and allow it to settle for a certain period of time, and can also be used to dissipate heat from the digested sample. During use, a collaborative robot 70 transfers the test liquid to the settling racks. The settling time depends on the test liquid, and different test liquids require different settling times.
[0070] The UV-Vis spectrophotometric detection module 40 of this embodiment places the test tube rack into the UV-Vis spectrophotometric detection equipment for concentration determination, purity determination, structural analysis, etc. It has 5 channels of automatic detection. After the detection is completed, this module has an automatic cleaning function and an automatic waste liquid discharge function.
[0071] Specifically, the spectrophotometric detection module 40 has a spectrophotometric detection station, which is equipped with a detector, a liquid aspiration mechanism, a transfer mechanism, and a rinsing mechanism. The transfer mechanism drives the liquid aspiration mechanism to transfer the liquid to be tested into the detector for detection, and the rinsing mechanism cleans the pipes of the spectrophotometric detection module 40. The spectrophotometric detection module 40 also has a cleaning station, which is equipped with a cleaning component for cleaning the liquid aspiration mechanism.
[0072] In this embodiment, spectrophotometric detection is performed using an ultraviolet light detector. First, a collaborative robot 70 moves the test liquid into the spectrophotometric detection module 40. The spectrophotometer has a liquid suction mechanism that can move up, down, left, right, forward, and backward. During detection, the liquid is drawn onto the detector using this mechanism. The detector then detects and judges the test liquid. Up to five test liquids can be detected simultaneously. After each liquid suction, the liquid suction mechanism needs to be moved to a cleaning station for cleaning.
[0073] In this embodiment of the automatic surface water testing device, the sample bottle and tray containing the test liquid are fed into the inlet. The tray and the bottle containing the test liquid, acting as internal circulation devices, enter the device through the feed inlet. After the sample tray and dispensing tray are ready, the type of test and related indicators to be performed are selected in the machine program, such as: surface water – total phosphorus, total nitrogen, and ammonia nitrogen. After selection, the machine is started, and it enters the preset program for automatic dispensing, automatic sample pretreatment, and testing. Different indicators can be run in parallel. Note that the specific parameters of the preset program must meet the corresponding laboratory procedure requirements. There will generally be residual liquid in the sample bottle. After all the liquid in the tray has been collected, the sample bottle and tray are automatically pushed out of the machine and transferred to the outlet. The dirty internal circulation devices and tray are automatically transferred to the outlet after use, waiting for the next sample tray to be fed in. Similarly, the dispensing bottle and dispensing tray are replenished as the test progresses.
[0074] The device has a total of 6 workstations, corresponding to the liquid separation module 10, loading and unloading module 20, liquid addition module 30, spectrophotometric detection module 40, settling module 50, and digestion module 60, arranged in a U-shape around the collaborative robot 70. The collaborative robot 70 moves the test liquid between the modules. The collaborative robot 70 facilitates the flow of the test liquid between different workstations. The detection process differs for different test liquids. By transferring the test liquid to the required detection station using the collaborative robot 70, the device can meet the different detection needs of various types of test liquids. Except for loading and unloading and liquid changing, which are performed manually, all other processes are automated. Different components or test solutions require different testing procedures. The corresponding testing procedures can be selected according to the different components or sample requirements. The collaborative robot 70 repeatedly picks up materials from the liquid separation module 10 and places them into the idle testing module, so that multiple tests can be carried out at the same time, saving time and improving testing efficiency. After all the test items of the test solution are completed, the collaborative robot 70 automatically puts the container tray back into the corresponding hopper of the loading and unloading module 20. After the original liquid bottle is extracted, the device closes the cap of the original liquid bottle and automatically puts the original liquid bottle back into the hopper, and then the manual unloading is performed.
[0075] The automatic surface water testing device in this embodiment features a modular design for each workstation. Each station can be used independently or multiple modules can be connected in series to form a testing process. Product transfer between modules can be accomplished manually or via a collaborative robot, creating an automated testing process. This modular design is suitable for various applications. Furthermore, the modular design facilitates disassembly and maintenance, and the sequence of each testing step can be adjusted to meet the testing requirements of different samples, making it highly flexible. Each module operates independently, allowing for simultaneous testing of different liquids without waiting, saving time and labor.
[0076] Although certain components and embodiments of this application have been illustrated and described, many modifications and alterations (e.g., variations in the size, dimensions, structure, shape and proportion of the various elements, installation arrangement, material use, color, orientation, etc.) will be conceived by those skilled in the art without actually departing from the scope and spirit of the claims.
[0077] Finally, it should be noted that the above embodiments are only preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
