[0002] Currently, during the production process of dairy products, there are many materials that need to be subjected to physical and chemical property detection. For example, fruit juice, jam, syrup, raw milk, milk powder, etc. all need to be subjected to physical and chemical property detection. Currently, when detecting the physical and chemical properties of materials, traditional detection modes are used for manual detection, and the detection efficiency is relatively low, thus failing to ensure the timely transfer of materials. Summary of the Invention

[0003] In view of this, the present invention provides a physical and chemical property detection method, device, equipment and system to solve the problem of relatively low detection efficiency of the physical and chemical properties of materials during the production process of dairy products.

[0004] In a first aspect, the present invention provides a physical and chemical property detection method, and the method includes the following steps: obtaining a sample to be detected and the theoretical detection items required for the sample to be detected, where the theoretical detection items are soluble solid content detection, density detection or impurity degree detection; determining the detection equipment corresponding to the theoretical detection items, and controlling the detection equipment to enter the detection preparation state; determining the detection position corresponding to the theoretical detection items, controlling the robotic arm to move the container containing the sample to be detected to the detection position, and controlling the detection equipment to detect the sample to be detected.

[0005] The physical and chemical property detection method provided in this embodiment, by obtaining the sample to be detected and the theoretical detection items required for the sample to be detected, where the theoretical detection items are soluble solid content detection, density detection or impurity degree detection; determining the detection equipment corresponding to the theoretical detection items, and controlling the detection equipment to enter the detection preparation state; controlling the robotic arm to move the container containing the sample to be detected to the detection position corresponding to the theoretical detection items, and controlling the detection equipment to detect the sample to be detected, can thereby automatically detect the physical and chemical properties and improve the detection efficiency.

[0006] In an optional implementation manner, determining the detection equipment corresponding to the theoretical detection items includes: when the theoretical detection item is soluble solid content detection, using the robotic arm and refractometer as the detection equipment; when the theoretical detection item is density detection, using the robotic arm and densitometer as the detection equipment; when the theoretical detection item is impurity degree detection, using the robotic arm, impurity degree filter, peristaltic pump, diaphragm pump and vision system as the detection equipment.

[0007] Thereby, the automation of soluble solid content detection, density detection and impurity degree detection can be achieved.

[0008] In an alternative embodiment, before controlling the robotic arm to move the sample to be tested to the detection position, the following steps are further included: controlling the robotic arm to move the detection sample to a preset barcode scanning position, and controlling the barcode scanner to scan the detection sample; obtaining the scanning information of the detection sample uploaded by the barcode scanner; determining the actual detection items of the detection sample according to the scanning information; when the actual detection items are the same as the theoretical detection items, determining that the detection sample is the sample to be tested, and executing the step of controlling the robotic arm to move the sample to be tested to the detection position.

[0009] This is because in the physical and chemical properties system, there are many samples to be tested, and there are often situations where the actual detection items of the samples are inconsistent with the detection items that the samples need to undergo. Therefore, it is necessary to scan the samples to be tested, determine the actual detection items of the detection samples according to the scanning information, that is, to further check the samples to be tested to prevent errors in the samples to be tested or detection items.

[0011] By setting up the pipeline system, the automation of soluble solid content detection can be achieved.

[0012] In an alternative embodiment, when the theoretical detection item is density detection, controlling the robotic arm to move the container containing the sample to be tested to the detection position and controlling the detection device to detect the sample to be tested includes: controlling the robotic arm to move the container containing the sample to be tested to below the pipeline system; controlling the pipeline system to transfer a second preset amount of the sample to be tested to a densitometer, and controlling the densitometer to detect the sample to be tested to obtain the density detection result of the sample to be tested.

[0013] By setting up the pipeline system, the automation of density detection can be achieved.

[0014] In an alternative embodiment, when the theoretical test item is impurity degree detection, controlling the robotic arm to move the container containing the sample to be tested to the detection position and controlling the detection device to test the sample to be tested includes: controlling the robotic arm to place the filter sheet into the funnel of the impurity degree filter, and pouring the sample to be tested in the container onto the filter sheet of the impurity degree filter; controlling the impurity degree filter to perform suction filtration; after the sample to be tested cannot be poured out of the container, controlling the robotic arm to move the container under the peristaltic pump to rinse the sample to be tested adhered to the inner wall of the container with the peristaltic pump to obtain a rinsing solution; controlling the robotic arm to pour the rinsing solution onto the filter sheet of the impurity degree filter and controlling the impurity degree filter to perform suction filtration until the sample to be tested adhered to the inner wall of the container is rinsed clean; starting the diaphragm pump to clean the inner wall of the funnel, controlling the impurity degree filter to perform suction filtration, and after the suction filtration is completed, controlling the vision system to take a photo of the filter sheet and analyzing the taken photo to obtain the impurity degree detection result of the sample to be tested.

[0015] Thus, not only can the automation of the impurity degree detection item be realized, but also the accuracy of the impurity degree detection result can be ensured.

[0016] In a second aspect, the present invention further provides a physical and chemical property detection device, which includes an acquisition module, a detection device determination module, a detection position determination module, a robotic arm control module, and a detection module; the acquisition module is used to acquire the sample to be tested and the theoretical test item that the sample to be tested needs to undergo, where the theoretical test item is soluble solid content detection, density detection, or impurity degree detection; the detection device determination module is used to determine the detection device corresponding to the theoretical test item and control the detection device to enter the detection preparation state; the detection position determination module is used to determine the detection position corresponding to the theoretical test item, and the robotic arm control module is used to control the robotic arm to move the container containing the sample to be tested to the detection position; the detection module is used to control the detection device to test the sample to be tested.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0030] According to an embodiment of the present invention, an embodiment of a physical and chemical property detection method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order than here.

[0031] In this embodiment, a physical and chemical property detection method is provided, which can be used in computer equipment. Figure 1 It is a flowchart of the physical and chemical property detection method according to an embodiment of the present invention, as Figure 1 shown, the process includes the following steps:

[0032] Step S101: Obtain the sample to be detected and the theoretical detection items required for the sample to be detected, where the theoretical detection items are soluble solid content detection, density detection or impurity degree detection.

[0033] Step S102: Determine the detection equipment corresponding to the theoretical detection item, and control the detection equipment to enter the detection preparation state.

[0034] In an optional implementation manner, when the theoretical detection item is soluble solid content detection, a refractometer is used as the detection equipment; when the theoretical detection item is density detection, a densitometer is used as the detection equipment; when the theoretical detection item is impurity degree detection, an impurity degree filter, a peristaltic pump, a diaphragm pump and a vision system are used as the detection equipment, where the peristaltic pump and the diaphragm pump are both connected to the impurity degree filter.

[0035] Step S103: Determine the detection position corresponding to the theoretical detection item.

[0036] Specifically, the detection equipment used for soluble solid content detection, density detection and impurity degree detection can be placed on an experimental bench. Since different theoretical detection items need to be detected by different detection equipment, the detection position of each theoretical detection item needs to be determined.

[0037] Step S104: Control the robotic arm to move the container containing the sample to be detected to the detection position, and control the detection equipment to detect the sample to be detected.

[0038] The physical and chemical property detection method provided in this embodiment can automatically detect physical and chemical properties and improve detection efficiency by obtaining the sample to be detected and the theoretical detection items required for the sample to be detected, where the theoretical detection items are soluble solid content detection, density detection or impurity degree detection; determining the detection equipment corresponding to the theoretical detection item and controlling the detection equipment to enter the detection preparation state; controlling the robotic arm to move the container containing the sample to be detected to the detection position corresponding to the theoretical detection item and controlling the detection equipment to detect the sample to be detected.

[0039] In this embodiment, a physical and chemical property detection method is provided, which can be used for computer devices. Figure 2 It is a flowchart of another physical and chemical property detection method according to an embodiment of the present invention. As Figure 2 shown, the process includes the following steps:

[0040] Step S201: Obtain the sample to be detected and the theoretical detection items required for the sample to be detected, where the theoretical detection items are soluble solid content detection, density detection, or impurity degree detection.

[0041] Step S202: When the theoretical detection item is soluble solid content detection, use a refractometer as the detection device and control the refractometer to enter the detection preparation state.

[0042] In the related art, the soluble solid content item is manually detected using an Abbe refractometer. In the embodiment of the present invention, in order to automatically detect the soluble solid content item, the Abbe refractometer is replaced with an automatic refractometer, and an automatic temperature control sensor is set in the refractometer to achieve automatic temperature control, one-key detection and uploading, replacing manual detection, reading, and temperature control.

[0043] Step S203: Control the robotic arm to move the test sample to a preset scanning position and control the scanner to scan the test sample.

[0044] Step S204: Obtain the scanning information of the test sample uploaded by the scanner.

[0045] Step S205: Determine the actual detection items of the test sample according to the scanning information.

[0046] Step S206: When the actual detection items are the same as the theoretical detection items, control the robotic arm to move the container containing the sample to be detected below the pipeline system.

[0047] Specifically, the pipeline system is connected to the refractometer.

[0048] Step S207: Control the refractometer to maintain at a preset first temperature, control the pipeline system to transfer a first preset amount of the sample to be detected into the refractometer, and control the refractometer to detect the sample to be detected to obtain the soluble solid content detection result of the sample to be detected.

[0049] In an alternative embodiment, after obtaining the soluble solid content detection result of the sample to be detected, it further includes: controlling the robotic arm to move the container containing the sample to be detected below the peristaltic pump; controlling the peristaltic pump to drain distilled water into the container containing the sample to be detected to clean the container containing the sample to be detected; and after the cleaning is completed, controlling the robotic arm to move the container containing the sample to be detected to a preset first position.

[0050] For example, the detection of soluble solids in a physical and chemical property detection system includes the following steps:

[0051] (1) The physical and chemical property detection system receives a detection task instruction, determines the sample to be detected and the theoretical detection items required for the sample to be detected according to the detection task instruction. When the theoretical detection item to be performed is the detection of soluble solids, it triggers the startup of the robotic arm, barcode scanner, peristaltic pump, and refractometer. In the maintenance program, it can be monitored that the system has been started, and in the device status program, it is shown that the robotic arm, barcode scanner, peristaltic pump, and refractometer are connected, and the detection work can begin.

[0052] (2) After receiving the detection task, the robotic arm opens the fixture to grab the sample bottle at the raw milk bottle tray, scans the sample bottle with the barcode scanner, and confirms whether the detection item is the soluble solids item. When the detection item is the soluble solids item, the sample in the sample bottle is poured into a 50 mL beaker placed on the beaker tray.

[0053] (3) The robotic arm puts down the sample bottle, picks up the sample beaker, places the sample beaker under the pipeline system, and the refractometer sucks a certain amount of the sample through the pipeline system into the refractometer detection area to start the detection. An automatic thermostat is designed inside the refractometer to control the sample temperature at 20 °C. The refractometer automatically reads the value, displays the detection result of the soluble solids item, and uploads the detection result to the laboratory LIMS system.

[0054] (4) The robotic arm pours the residual sample in the beaker into the waste liquid collection place, picks up the sample beaker and places it under the peristaltic pump. The peristaltic pump automatically discharges distilled water into the beaker, and the robotic arm shakes the beaker for cleaning twice. After cleaning, the robotic arm places the beaker on the beaker tray.

[0055] It should be noted that if it is found before the detection that the robotic arm, barcode scanner, peristaltic pump, and refractometer are not connected, an alarm reminder will be given. If it is found during the detection that the amount of the sample poured into the beaker is insufficient or the sample is not aspirated (an automatic liquid level sensor is set, and if it is found to be insufficient, an automatic alarm reminder will be given through the alarm system), or if the beaker is not placed in the fixed position after the detection, etc., an alarm reminder will be given. At the same time, it can be monitored in real time in the detection information program that the detection of the soluble solids item has been completed.

[0056] In this embodiment, a physical and chemical property detection method is provided, which can be used in a computer device. Figure 3 It is a flowchart of another physical and chemical property detection method according to an embodiment of the present invention. As Figure 3 shown, the process includes the following steps:

[0057] Step S301: Obtain the sample to be tested and the theoretical test items required for the sample to be tested, where the theoretical test items are soluble solid content test, density test or impurity degree test.

[0058] Step S302: When the theoretical test item is the density test, use the densitometer as the test equipment and control the densitometer to enter the test preparation state.

[0059] Step S303: Control the robotic arm to move the test sample to the preset code scanning position, and control the barcode scanner to scan the test sample.

[0060] Step S304: Obtain the scanning information of the test sample uploaded by the barcode scanner.

[0061] Step S305: Determine the actual test items of the test sample according to the scanning information.

[0062] Step S306: When the actual test items are the same as the theoretical test items, control the robotic arm to move the container containing the sample to be tested below the pipeline system.

[0063] Step S307: Control the pipeline system to transfer a second preset amount of the sample to be tested into the densitometer, and control the densitometer to test the sample to be tested to obtain the density test result of the sample to be tested.

[0064] In an optional implementation manner, after obtaining the soluble solid content test result of the sample to be tested, it further includes: controlling the robotic arm to move the container containing the sample to be tested below the peristaltic pump; controlling the peristaltic pump to drain distilled water into the container containing the sample to be tested to clean the container containing the sample to be tested; and after the cleaning is completed, controlling the robotic arm to move the container containing the sample to be tested to a preset second position.

[0065] Exemplarily, the density test in the physical and chemical property detection system includes the following steps:

[0066] (1) The physical and chemical property detection system receives the test task instruction, determines the sample to be tested and the theoretical test items required for the sample to be tested according to the test task instruction. When the required theoretical test item is the density test, trigger the robotic arm, barcode scanner, peristaltic pump, and densitometer to turn on. In the maintenance program, it can be monitored that the system has been started, and in the device status program, it is shown that the robotic arm, barcode scanner, peristaltic pump, and densitometer have been connected, and the test work can start.

[0067] (2) After receiving the test task, the robotic arm opens the fixture to grab the sample bottle at the raw milk bottle tray, scans the sample bottle with the barcode scanner, and confirms whether the test item is relative density. When the test item is relative density, pour the sample into a 50 mL beaker placed on the beaker tray.

[0068] (3) The robotic arm lowers the sample bottle, picks up the sample beaker, places the sample beaker under the pipeline system, and the densitometer sucks a certain amount of the sample into the densitometer detection area through the pipeline system to start the detection. The densitometer automatically takes readings, displays the detection results of the relative density item, and uploads the detection results to the laboratory LIMS system.

[0069] (4) The robotic arm pours the residual sample in the beaker into the waste liquid collection place, picks up the sample beaker and places it under the peristaltic pump. The peristaltic pump automatically discharges distilled water into the beaker, and the robotic arm shakes the beaker for cleaning. After cleaning twice, the robotic arm places the beaker on the beaker tray.

[0070] It should be noted that if the robotic arm, barcode scanner, peristaltic pump, and densitometer are not connected before the detection, an alarm reminder will be given. If the amount of the sample poured into the beaker is insufficient or the sample is not sucked during the detection, an alarm reminder will be given. If the beaker is not placed in the fixed position after the detection, etc., an alarm reminder will be given. At the same time, the detection of the relative density item that has been completed can be monitored in real time in the detection information program.

[0071] In this embodiment, a physical and chemical property detection method is provided, which can be used in computer equipment. Figure 4 It is a flowchart of another physical and chemical property detection method according to the embodiment of the present invention, as Figure 4 shown, and the process includes the following steps:

[0072] Step S401: Obtain the sample to be detected and the theoretical detection items required for the sample to be detected, where the theoretical detection items are soluble solid content detection, density detection, or impurity degree detection.

[0073] Step S402: When the theoretical detection item is impurity degree detection, use the impurity degree filter, peristaltic pump, diaphragm pump, and vision system as the detection equipment, and control the detection equipment to enter the detection preparation state.

[0074] Among them, both the peristaltic pump and the diaphragm pump are connected to the impurity degree filter.

[0075] Step S403: Control the robotic arm to move the detection sample to the preset barcode scanning position, and control the barcode scanner to scan the detection sample.

[0076] Step S404: Obtain the scanning information of the detection sample uploaded by the barcode scanner.

[0077] Step S405: Determine the actual detection items of the detection sample according to the scanning information.

[0078] Step S406: When the actual detection items are the same as the theoretical detection items, control the robotic arm to place the filter disc into the funnel of the impurity degree filter.

[0079] Step S407: Control the robotic arm to place the filter sheet into the funnel of the impurity degree filter, and pour the sample to be tested in the container onto the filter sheet of the impurity degree filter.

[0080] Step S408: Control the impurity degree filter to perform suction filtration.

[0081] Step S409: After the sample to be tested cannot be poured out of the container, control the robotic arm to move the container below the peristaltic pump to wash the sample to be tested adhering to the inner wall of the container by using the peristaltic pump to obtain a washing solution.

[0082] Step S410: Control the robotic arm to pour the washing solution onto the filter sheet of the impurity degree filter, and control the impurity degree filter to perform suction filtration until the sample to be tested adhering to the inner wall of the container is washed clean.

[0083] Step S411: Start the diaphragm pump to clean the inner wall of the funnel, control the impurity degree filter to perform suction filtration, and after the suction filtration is completed, control the vision system to take a photo of the filter sheet and analyze the photo taken to obtain the impurity degree detection result of the sample to be tested.

[0084] Exemplarily, the impurity degree detection in the physical and chemical property detection system includes the following steps:

[0085] (1) The physical and chemical property detection system receives a detection task instruction, determines the sample to be tested and the theoretical detection items required for the sample to be tested according to the detection task instruction. When the theoretical detection item to be performed is soluble solid content detection, trigger the robotic arm, barcode scanner, peristaltic pump, vision system, impurity degree filter, and diaphragm pump to start. In the maintenance program, it can be monitored that the system has been started, and in the device status program, it is shown that the robotic arm, barcode scanner, peristaltic pump, vision system, impurity degree filter, and diaphragm pump have been connected and the detection work can start.

[0086] (2) The robotic arm places the filter disc into the funnel of the impurity degree filter instrument, and after placing the filter disc into the funnel of the impurity degree filter instrument, the clamp is opened. The clamp grabs the graduated cylinder containing the sample on the graduated cylinder device, and scans the code with the barcode scanner to confirm whether the test item is the impurity degree test; when the test item is the impurity degree test, the robotic arm pours the milk sample into the funnel of the impurity degree filter instrument, and the impurity degree filter instrument automatically starts and begins the filtering step. The impurity degree filter instrument will automatically perform suction filtration. After all the milk sample is poured into the funnel of the impurity degree filter instrument for suction filtration, the robotic arm places the graduated cylinder under the peristaltic pump. The peristaltic pump automatically discharges distilled water into the volumetric cylinder for the first rinsing, the second rinsing, and the third rinsing, and sequentially pours the rinsing solutions into the funnel of the impurity degree filter instrument. Subsequently, the robotic arm places the graduated cylinder back on the graduated cylinder device, and automatically starts the diaphragm pump. The robotic arm grabs the spray head to rinse the inner periphery of the funnel of the impurity degree filter instrument.

[0087] (3) After the rinsing is completed, the vision system takes a photo of the impurity degree filter disc. The vision system compares the sample picture with the standard picture to obtain the test result, and uploads the test result to the laboratory LIMS system.

[0088] (4) After taking the photo, the robotic arm discards the filter disc to the waste collection place.

[0089] It should be noted that if the robotic arm, barcode scanner, peristaltic pump, vision system, impurity degree filter instrument, and diaphragm pump are not connected before the test, an alarm reminder will be given. If there are machine failures in the beaker, abnormal vision photography, etc. during the test, an alarm reminder will be given. If the graduated cylinder, etc. are not placed in the fixed position after the test, an alarm reminder will be given. At the same time, the completion of the impurity degree test item can be monitored in real time in the test information program.
