DETAILED DESCRIPTION

[0044] In order to make the purpose, technical scheme and advantages of the present application clearer, the technical scheme of the present application will be described clearly and completely below in combination with the drawings in the present application. Obviously, the described embodiments are some embodiments of the present application, rather than all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0045] The density detection work station provided by the embodiments of the present application will be described in detail below in combination with specific embodiments and application scenarios. Figures 1-5

[0046] In some embodiments, as shown in Figures 1 to 4 the density detection work station comprises a sample placement device 1, a sample suction device 2, a sample buffer device 3, a sample injection device 4 and a density detection mechanism 5. The sample placement device 1 is used for temporarily storing a tank 6 containing a sample; the sample suction device 2 is used for sucking the sample in the tank 6 in the sample placement device 1; the sample buffer device 3 comprises a rotating disc 31 and a detection cylinder 32 arranged on the rotating disc 31, and the rotating disc 31 is suitable for driving the detection cylinder 32 to move between a detection station and a liquid injection station; the sample injection device 4 is in communication with the sample suction device 2, and the sample injection device 4 is configured to inject the sample sucked by the sample suction device 2 into the detection cylinder 32 at the liquid injection station; and the density detection mechanism 5 is configured to detect the density of the sample in the detection cylinder 32 at the detection station.

[0047] ​In this embodiment, the sample placement device 1 serves as a temporary storage for the sample containers 6 containing the sample to be measured. These sample containers 6 usually contain liquid (usually milk) that needs to be measured for density. The sample suction device 2 is responsible for sucking the sample from the sample containers 6 in the sample placement device 1. The sample containers 6 can usually be precisely located by a mechanical arm, and a certain amount of sample can be effectively sucked. The role of the carousel 31 of the sample buffer device 3 is to move the measuring cylinders 32 between the measuring station and the sample injection station. When the measuring cylinder 32 is in the sample injection station, it can receive the sample from the sample injection device 4; when it moves to the measuring station, it can perform density measurement. The sample injection device 4 is connected to the sample suction device 2 and is responsible for injecting the sucked sample into the measuring cylinder 32 in the sample injection station. This ensures that the sample can be accurately and quickly transferred to the measuring cylinder 32, preparing for subsequent density measurement. The density measurement mechanism 5 measures the density of the sample in the measuring cylinder 32 in the measuring station.

[0048] During the operation of the density measurement station, the sample containers 6 containing the sample are first placed on the sample placement device 1. These sample containers 6 may have been pre-processed, such as mixing, temperature adjustment, etc., to ensure the accuracy of the measurement results. The sample placement device 1 has an identification function, which can identify the type, position and whether it contains the sample to be measured.

[0049] The sample suction device 2 is started, moves above the sample placement device 1, and accurately aligns the sample position in the sample container 6. The suction device starts to work, using negative pressure or positive pressure technology to suck a certain amount of sample into the suction device. The sample suction device 2 transfers the sucked sample to the measuring cylinder 32 in the sample buffer device 3. During this process, the carousel 31 may have moved to the sample injection station, waiting to receive the sample. After the sample injection is completed, the carousel 31 starts to rotate, moving the measuring cylinder 32 from the sample injection station to the measuring station.

[0050] When the measuring cylinder 32 reaches the measuring station, the density measurement mechanism 5 starts to work to measure the density of the sample. After the measurement is completed, the density measurement mechanism 5 sends the result to the data recording system or the display screen for the operator to view.

[0051] The density detection work station provided by the utility model, through setting sample placement device 1, sample suction device 2, sample buffer device 3, sample injection device 4 and density detection mechanism 5, automatic suction, buffering, injection and density detection of sample are realized, and detection time is greatly shortened. Meanwhile, through the setting of turntable 31 and detection cylinder 32, the detection process is more smooth, the operation times and waiting time of detection personnel are reduced, and the overall detection efficiency is improved. The density detection work station can accurately measure the density value of sample, and avoids the error caused by human factors in the traditional method. Meanwhile, through automatic operation, the interference factors in the operation process are reduced, and the accuracy of detection result is improved.

[0052] In some embodiments, as shown in Figures 1 to 4 The sample suction device 2 has a suction mode and a stop mode, and the sample suction device 2 comprises a suction pump, a suction pipeline 21 and a first driving mechanism 22. The suction pump is connected with the suction pipeline 21, the suction pipeline 21 is communicated with the sample injection device 4, the suction pipeline 21 is arranged on the driving end of the first driving mechanism 22, and the first driving mechanism 22 is suitable for driving the suction pipeline 21 to move; in the case of the suction mode, the first driving mechanism 22 drives the suction pipeline 21 to be inserted into the jar body 6 in the sample placement device 1, and the suction pump draws the sample in the jar body 6 to the sample injection device 4 through the suction pipeline 21; in the case of the stop mode, the first driving mechanism 22 drives the suction pipeline 21 to move out of the jar body 6 in the sample placement device 1, and the suction pump stops drawing the sample in the jar body 6.

[0053] In the embodiment, the suction pump is responsible for generating negative pressure or positive pressure to draw the sample out of the jar body 6. The suction pipeline 21 is connected with the suction pump and plays a role in transmitting the sample. One end of the suction pipeline 21 is connected with the suction pump, and the other end is communicated with the sample injection device 4. The first driving mechanism 22 is used for driving the movement of the suction pipeline 21.

[0054] When the sample suction device 2 is in the suction mode, the first driving mechanism 22 starts to work and drives the suction pipeline 21 to move towards the jar body 6 in the sample placement device 1. The suction pipeline 21 gradually inserts into the jar body 6 until a predetermined position and depth are reached. The specific position and depth can be adjusted according to the properties of the sample and the detection requirements. At the same time, the suction pump starts to work and draws the sample in the jar body 6 out through the suction pipeline 21 and transports it to the sample injection device 4. When it is necessary to stop suction, the first driving mechanism 22 works again, but this time it drives the suction pipeline 21 to move out of the jar body 6. The suction pipeline 21 gradually exits from the jar body 6 until it completely leaves the jar body 6. At the same time, the suction pump stops working and no longer draws the sample in the jar body 6. The whole suction process is automatic and does not need manual intervention, greatly improving the work efficiency and accuracy.

[0055] In some embodiments, as shown inFigure 1 and Figure 2 As shown in FIGS. 1-2, the sample suction device 2 is provided with two suction pipes 21; in the suction mode, the first driving mechanism 22 drives at least one of the suction pipes 21 to be inserted into the tank 6 in the sample placement device 1, and the suction pump draws the sample in the tank 6 through the at least one suction pipe 21 and into the sample injection device 4; in the stop mode, the first driving mechanism 22 drives both of the suction pipes 21 to move out of the tank 6 in the sample placement device 1, and the suction pump stops drawing the sample in the tank 6.

[0056] When the sample suction device 2 is in the suction mode, the first driving mechanism 22 starts to work and drives at least one (or both) of the suction pipes 21 to move towards the tank 6 in the sample placement device 1. The at least one suction pipe 21 gradually inserts into the tank 6 to a predetermined position and depth. At the same time, the suction pump starts to work and draws the sample in the tank 6 through the at least one suction pipe 21 and into the sample injection device 4. The user can flexibly choose to use one or two suction pipes 21 for sample suction, depending on the specific detection requirements, sample amount, and suction efficiency, etc.

[0057] When it is necessary to stop suction, the first driving mechanism 22 works again, but this time it drives both of the suction pipes 21 to move out of the tank 6 at the same time. The two suction pipes 21 gradually withdraw from the tank 6 until they completely leave the tank 6. At the same time, the suction pump stops working and no longer draws the sample in the tank 6.

[0058] In some embodiments, as shown in FIGS. 3-4, the first driving mechanism 22 includes a first linear module 221 and a first driving member 222; the first driving member 222 is arranged on the slide table of the first linear module 221, the driving end of the first driving member 222 is connected with the suction pipe 21, the first linear module 221 is used to drive the first driving member 222 and the suction pipe 21 on the slide table to move along the length direction of the density detection work station, and the first driving member 222 is used to drive the suction pipe 21 to move along the height direction of the density detection work station. Figure 4 Figure 5 Specifically, the first linear module 221 is a linear motion mechanism, which is usually composed of a guide rail, a slide table (a slide block), a driving motor, a transmission device, etc. The first linear module 221 is responsible for driving the first driving member 222 and the suction pipe 21 on the slide table to move along the length direction of the density detection work station. The first driving member 222 is a mechanism capable of generating linear or rotary motion, such as a pneumatic cylinder, an electric push rod, a servo motor, etc. The first driving member 222 is installed on the slide table of the first linear module 221 and is responsible for driving the suction pipe 21 to move along the height direction of the density detection work station.

[0059] Specifically, the first linear module 221 is a linear motion mechanism, which is usually composed of a guide rail, a slide table (a slide block), a driving motor, a transmission device, etc. The first linear module 221 is responsible for driving the first driving member 222 and the suction pipe 21 on the slide table to move along the length direction of the density detection work station. The first driving member 222 is a mechanism capable of generating linear or rotary motion, such as a pneumatic cylinder, an electric push rod, a servo motor, etc. The first driving member 222 is installed on the slide table of the first linear module 221 and is responsible for driving the suction pipe 21 to move along the height direction of the density detection work station.

[0060] ​When it is necessary to change the position of the suction pipe 21 along its length, the first linear module 221 begins to operate. The drive motor drives the slide (slider) to slide on the guide rail via a transmission device, thereby moving the first drive unit 222 and the suction pipe 21 together. This movement can be continuous or intermittent, depending on the control signal and the type of drive motor.

[0061] When it is necessary to change the position of the suction pipe 21 in the vertical direction, the first driving component 222 starts to work. It can be the extension and retraction of a cylinder, the extension and retraction of an electric push rod, or the rotation of a servo motor, etc. Driven by the first driving component 222, the suction pipe 21 can move up and down in a direction perpendicular to its length, thereby achieving precise suction of the sample in the container 6.

[0062] In some embodiments, such as Figure 4 and Figure 5 As shown, the sample injection device 4 has an injection mode and a standby module, including: an injection pump, an injection nozzle 41, and a second drive mechanism 42; the injection nozzle 41 is connected to the sample aspiration device 2 through the injection pump, and the injection nozzle 41 is disposed at the drive end of the second drive mechanism 42, which is adapted to drive the injection nozzle 41 to move; in the injection mode, the second drive mechanism 42 drives the injection nozzle 41 to move into the measuring cylinder 32, and the injection pump injects the sample into the measuring cylinder 32 through the injection nozzle 41; in the standby mode, the second drive mechanism 42 drives the injection nozzle 41 to move out of the measuring cylinder 32, and the injection pump stops injecting the sample.

[0063] In this embodiment, the syringe pump generates pressure or negative pressure to push the sample into the measuring cylinder 32. The injection nozzle 41 is connected to the syringe pump and serves to transfer and inject the sample. One end of it is connected to the syringe pump, and the other end is used to inject the sample into the measuring cylinder 32. The second drive mechanism 42 is used to drive the movement of the injection nozzle 41.

[0064] When in injection mode, the second drive mechanism 42 activates, driving the injection nozzle 41 to move towards the measuring cylinder 32. The injection nozzle 41 gradually approaches the opening of the measuring cylinder 32 until it reaches the predetermined injection position. This position can be adjusted according to the size of the measuring cylinder 32 and the properties of the sample.

[0065] Simultaneously, the syringe pump starts working, pushing the sample from the sample aspiration device 2 into the measuring cylinder 32 through the injection nozzle 41. After injection, the syringe pump stops working, but the injection nozzle 41 may remain in the injection position, awaiting the next operation.

[0066] When it is necessary to stop the injection or to perform other operations, the second driving mechanism 42 works again, but this time it drives the injection nozzle 41 to move out of the detection cylinder 32. The injection nozzle 41 gradually moves away from the opening of the detection cylinder 32 until it completely leaves the injection area of the detection cylinder 32. At the same time, the injection pump also stops working and no longer injects the sample into the detection cylinder 32.

[0067] In some embodiments, as shown in Figure 4 and Figure 5 The second driving mechanism 42 includes a second driving member 421 and a third driving member 422. The driving end of the second driving member 421 is connected with the third driving member 422, and the driving end of the third driving member 422 is connected with the injection nozzle 41. The second driving member 421 is used to drive the third driving member 422 and the injection nozzle 41 to move along the width direction of the density detection work station, and the third driving member 422 is used to drive the injection nozzle 41 to move along the height direction of the density detection work station.

[0068] Specifically, the second driving member 421 is a mechanism capable of producing linear or rotary motion, such as a pneumatic cylinder, an electric push rod, a servo motor, etc. It is responsible for driving the third driving member 422 and the injection nozzle 41 to move along the width direction of the density detection work station. The third driving member 422 is also a mechanism capable of producing linear or rotary motion, similar to the second driving member 421. It is installed on the driving end of the second driving member 421 and is responsible for driving the injection nozzle 41 to move along the height direction of the density detection work station. The injection nozzle 41 is connected with the injection pump and is used to inject the sample into the detection cylinder 32. The injection nozzle 41 is installed on the driving end of the third driving member 422 and moves with the third driving member 422.

[0069] When it is necessary to change the position of the injection nozzle 41 in the width direction, the second driving member 421 starts to work. Through the driving of the second driving member 421, the third driving member 422 and the injection nozzle 41 move together along the width direction. When it is necessary to change the position of the injection nozzle 41 in the height direction, the third driving member 422 starts to work. Through the driving of the third driving member 422, the injection nozzle 41 moves up and down along a direction perpendicular to the width direction, thereby achieving precise control of the injection height.

[0070] In some embodiments, as shown in Figure 1 The density detection mechanism 5 includes a densimeter 51, a thermometer 52, a third driving mechanism 53, and a visual mechanism 54. The driving end of the third driving mechanism 53 is connected with the densimeter 51 and the thermometer 52. During the detection process, the third driving mechanism 53 is used to drive the densimeter 51 and the thermometer 52 to move into the detection cylinder 32, and the visual mechanism 54 is used to visually identify the detection results of the densimeter 51 and the thermometer 52.

[0071] In this embodiment, the densimeter 51 is used to measure the density of the sample. It generally has high precision and stability, and can accurately reflect the physical properties of the sample. The thermometer 52 is used to measure the temperature during detection, to ensure that the temperature is within a suitable range and to avoid errors in density detection. The third driving mechanism 53 can drive the densimeter 51 and the thermometer 52 to move into the detection cylinder 32 for density and temperature measurement. The vision mechanism 54 is used for visual recognition of the detection results of the densimeter 51 and the thermometer 52.

[0072] Before the detection starts, the third driving mechanism 53 moves the densimeter 51 and the thermometer 52 to the preset starting position. At the same time, the vision mechanism 54 is also initialized, ready to receive and process image data. When the detection instruction is received, the third driving mechanism 53 starts to work, driving the densimeter 51 and the thermometer 52 to move together into the detection cylinder 32. During this process, the densimeter 51 and the thermometer 52 are aligned with the detection cylinder 32 to ensure the accuracy of the measurement. When the densimeter 51 and the thermometer 52 enter the detection cylinder 32, they start to measure the density and temperature. During the measurement or after the measurement, the vision mechanism 54 captures the display results of the densimeter 51 and the thermometer 52, and recognizes and analyzes them through image processing algorithms. Finally, the results recognized by the vision mechanism 54 are output as the final density and temperature data. These data can be used for further analysis, reporting or storage.

[0073] In some embodiments, as shown in Figure 4 and Figure 5 The third driving mechanism 53 includes a second linear module 531, a fourth driving member 532 and a fifth driving member 533. The fourth driving member 532 is provided on the slide table of the second linear module 531, the driving end of the fourth driving member 532 is connected with the fifth driving member 533, and the driving end of the fifth driving member 533 is connected with the densimeter 51 and the thermometer 52. The second linear module 531 is used to drive the fourth driving member 532, the fifth driving member 533, the densimeter 51 and the thermometer 52 on the slide table to move along the length direction of the density detection work station. The fourth driving member 532 is used to drive the fifth driving member 533, the densimeter 51 and the thermometer 52 to move along the width direction of the density detection work station. The fifth driving member 533 is used to drive the densimeter 51 and the thermometer 52 to move along the height direction of the density detection work station.

[0074] In particular, the second linear module 531 is a linear motion mechanism, typically composed of guide rails, a sliding table (slider), a drive motor, and a transmission device. It is responsible for driving the fourth drive 532, the fifth drive 533, the densimeter 51, and the thermometer 52 on the sliding table to move along the length direction of the density detection station. The fourth drive 532 is a mechanism capable of producing linear motion, such as a pneumatic cylinder, an electric push rod, a servo motor, etc. The fourth drive 532 is installed on the sliding table of the second linear module 531, responsible for driving the fifth drive 533, the densimeter 51, and the thermometer 52 to move along the width direction of the density detection station. The fifth drive 533 is also a mechanism capable of producing linear motion, similar to the fourth drive 532. It is installed on the driving end of the fourth drive 532, responsible for driving the densimeter 51 and the thermometer 52 to move along the height direction of the density detection station. The densimeter 51 and the thermometer 52 are used to measure the density and temperature of the sample, respectively. They are connected to the driving end of the fifth drive 533 through connectors or supports, and move with the fifth drive 533.

[0075] When it is necessary to change the position of the densimeter 51 and the thermometer 52 in the length direction, the second linear module 531 starts to work. The drive motor drives the sliding table to slide on the guide rail through the transmission device, thereby driving the fourth drive 532, the fifth drive 533, the densimeter 51, and the thermometer 52 to move together.

[0076] When it is necessary to change the position of the densimeter 51 and the thermometer 52 in the width direction, the fourth drive 532 starts to work. Through the driving of the fourth drive 532, the fifth drive 533, the densimeter 51, and the thermometer 52 move together along the width direction. When it is necessary to change the position of the densimeter 51 and the thermometer 52 in the height direction, the fifth drive 533 starts to work. Through the driving of the fifth drive 533, the densimeter 51 and the thermometer 52 move up and down along the direction perpendicular to the length and width directions to achieve measurement at different height positions.

[0077] The third drive mechanism 53 of the density detection mechanism 5 achieves precise control of the densimeter 51 and the thermometer 52 in three dimensions by adopting the combination design of the second linear module 531, the fourth drive 532, and the fifth drive 533, not only improving the flexibility and efficiency of the station, but also ensuring the accuracy and stability of the detection process.

[0078] In some embodiments, as Figures 1 to 5As shown, the density detection station further comprises a cleaning mechanism 7 disposed on one side of the detection cylinder 32; the density detection mechanism 5 has a detection mode and a cleaning mode; in the detection mode, the third driving mechanism 53 drives the densimeter 51 and the thermometer 52 to move into the detection cylinder 32, and the visual mechanism 54 is used for visually identifying the detection results of the densimeter 51 and the thermometer 52; in the cleaning mode, the third driving mechanism 53 drives the densimeter 51 and the thermometer 52 to move into the cleaning mechanism 7 for cleaning.

[0079] In this embodiment, the detection cylinder 32 is used to accommodate the sample to be detected, and the density detection mechanism 5 includes components such as the densimeter 51, the thermometer 52, the third driving mechanism 53, and the visual mechanism 54, which are used to measure the density and temperature of the sample and identify the measurement results through the visual mechanism 54. The cleaning mechanism 7 is used to clean the densimeter 51 and the thermometer 52 after detection to remove residual samples or contaminants. The cleaning mechanism 7 includes components such as a cleaning tank, a cleaning liquid supply system, a cleaning brush or a spray head.

[0080] When the density detection mechanism 5 is in the detection mode, the third driving mechanism 53 drives the densimeter 51 and the thermometer 52 to move into the detection cylinder 32. The densimeter 51 and the thermometer 52 measure the density and temperature of the sample, respectively. The visual mechanism 54 captures the display results of the densimeter 51 and the thermometer 52 and visually identifies them, and converts the identification results into digital data. The visual mechanism 54 outputs the measurement results to the operator or for further analysis and processing.

[0081] When the density detection mechanism 5 is in the cleaning mode, the third driving mechanism 53 drives the densimeter 51 and the thermometer 52 to move out of the detection cylinder 32 and into the cleaning mechanism 7. The cleaning mechanism 7 starts working and cleans the densimeter 51 and the thermometer 52 through components such as cleaning liquid, cleaning brush or spray head. The cleaning process may involve multiple steps such as soaking, brushing, rinsing, etc. to ensure that the residual sample or contaminants are completely removed. After cleaning is completed, the third driving mechanism 53 moves the densimeter 51 and the thermometer 52 back to the initial position or the detection position, preparing for the next detection.

[0082] In addition, an ejection mechanism can be additionally provided at the bottom of the detection cylinder 32, which is used to eject the sample after the detection is completed. The ejection mechanism can be a valve, a pump or other mechanism capable of controlling the flow of liquid. The ejection mechanism is provided so that the sample can be conveniently removed to prepare for the next detection. Generally, after the detection is completed, the ejection mechanism starts to work to eject the sample in the detection cylinder 32. After the ejection is completed, the turntable 31 can move the detection cylinder 32 to the cleaning station (if the cleaning mechanism 7 is separately provided from the detection station), or directly to the cleaning station if the cleaning mechanism 7 is integrated with the detection station. The cleaning mechanism 7 cleans the densimeter 51 and the thermometer 52 to remove the residual sample or contaminants. After the cleaning is completed, the turntable 31 moves the detection cylinder 32 back to the injection station for the next detection. The density detection station further optimizes the work flow, improves the detection efficiency and automation level by introducing the ejection mechanism.

[0083] In some embodiments, the sample placement device 1 comprises a carrying table 11. The carrying table 11 serves as the basic structure of the sample placement device 1, which provides a stable and flat support surface for placing the canister 6. The carrying table 11 can be made of metal, plastic or other solid and durable materials to ensure its load-bearing capacity and durability. A plurality of accommodation grooves for placing the canister 6 are provided on the carrying table 11. The shape, size and depth of these accommodation grooves can be customized according to the shape and size of the canister 6 to ensure that the canister 6 can be stably placed in the accommodation grooves and is not easy to slip or tilt. The number of accommodation grooves can be set according to actual needs to accommodate multiple canisters 6, thereby improving the detection efficiency.
