[0050] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0051] Combine the following Figure 1-Figure 9 , the total solids detection station for dairy products provided by the utility model embodiment is described in detail through specific embodiments and their application scenarios.

[0052] like Figure 1 and Figure 2 As shown, the embodiment of the utility model provides a total solids detection station for dairy products, comprising: a vessel buffer unit 1, a sample pretreatment unit 2, a transfer unit 3, a drying unit 4, a weighing unit 5 and a data processing unit;

[0053] The vessel buffer unit 1 is used to buffer the vessel 100, which may be a flat bottomed dish equipped with a lid; the sample pretreatment unit 2 is used to shake and uncap the centrifuge tube 200 containing the dairy product;

[0054] The transfer unit 3 is used to pick up the vessel 100 from the vessel buffer unit 1, take samples from the centrifuge tube 200 of the sample pretreatment unit 2, transfer the sampled dairy product to the vessel 100, and control the vessel 100 to move between the drying unit 4 and the weighing unit 5;

[0055] The drying unit 4 is used to dry the dairy product in the container 100; the weighing unit 5 may be an electronic level, and the weighing unit 5 is used to weigh the weight of the container 100 before and after adding the dairy product, and to weigh the weight of the container 100 after the dairy product is dried;

[0056] The data processing unit is used to obtain the total solid content in the dairy product according to the weighing data fed back by the weighing unit 5 .

[0057] In the actual detection operation, the vessel cache unit 1 can cache the vessel 100 containing the heating medium, the transfer unit 3 is used to transfer the cached vessel 100 to the drying unit 4, the drying unit 4 is used to dry the vessel 100, the transfer unit 3 is used to transfer the dried vessel 100 to the weighing unit 5, the weighing unit 5 is used to weigh the vessel 100 and obtain the first weighing data; at the same time, the sample pretreatment unit 2 is used to shake and open the centrifuge tube 200 containing the dairy product, the transfer unit 3 is used to sample the dairy product from the centrifuge tube 200, and transfer the sampled dairy product to be tested. The sample is transferred to the vessel 100 on the weighing unit 5; the weighing unit 5 is used to perform a second weighing on the vessel 100 to obtain second weighing data; the transfer unit 3 is also used to transfer the vessel 100 that has completed the second weighing to the drying unit 4, the drying unit 4 is used to perform a second drying process on the vessel 100, the transfer unit 3 is used to transfer the vessel 100 after the second drying to the weighing unit 5, the weighing unit 5 is used to perform a third weighing on the vessel 100 to obtain third weighing data; the data processing unit obtains the total solid content in the dairy product according to the first weighing data, the second weighing data and the third weighing data fed back by the weighing unit 5.

[0058] From the above, it can be seen that the total solids detection station for dairy products shown in the utility model can automatically complete the detection of the total solids content in dairy products. The entire detection process does not require human participation, which reduces the detection cost, improves the detection efficiency, ensures the accuracy of the total solids content detection results, and can meet large-scale detection needs.

[0059] It should be noted that, in the process of total solids detection of dairy products, by placing a heating medium in the vessel 100, the dairy products can be prevented from agglomerating during the drying process, while increasing the heating and evaporation area of ​​the dairy products, accelerating the evaporation of water, and shortening the detection time. The heating medium can be sea sand or quartz sand.

[0060] At the same time, the sample pretreatment unit 2 can ensure that the dairy products in the centrifuge tube 200 are evenly dispersed by shaking the centrifuge tube 200 to ensure the accuracy of the test results. By opening the cover of the centrifuge tube 200, it is convenient for the transfer unit 3 to perform sampling operations of dairy products from the centrifuge tube 200.

[0061] Among them, the total solids detection station for dairy products is equipped with a pipette rack 6, on which a plurality of pipette tips are placed; the transfer unit 3 is equipped with a pipette 323, which can be connected to the pipette tip. Under the drive of the transfer unit 3, the pipette 323 controls the pipette tip to absorb dairy products from the centrifuge tube 200 to realize the sampling operation of dairy products.

[0062] In addition, the data processing unit can adopt a single chip microcomputer or a PLC controller, and the data processing unit is respectively connected with the sample pretreatment unit 2, the transfer unit 3, the drying unit 4 and the weighing unit 5 to realize the automatic control of the whole detection process.

[0063] In practical applications, the data processing unit can obtain the total solid content in the dairy product according to the following calculation formula known in the art:

[0064] ;

[0065] In the above formula, X represents the total solid content in the dairy product, m1 represents the first weighing data obtained by the weighing unit 5 weighing the container 100 once, and the unit is g; m2 represents the second weighing data obtained by the weighing unit 5 weighing the container 100 twice, and the unit is g; m3 represents the third weighing data obtained by the weighing unit 5 weighing the container 100 three times, and the unit is g.

[0066] In some embodiments, Figure 1 and Figure 2 As shown, the drying unit 4 includes a heat drying mechanism 42 and a dryer 43; the heat drying mechanism 42 is used to use hot air to heat-dry the vessel 100, and the transfer unit 3 is used to transfer the vessel 100 that has completed the heat drying treatment to the dryer 43; the dryer 43 is used to dry the vessel 100, and the transfer unit 3 is also used to transfer the vessel 100 that has completed the drying treatment to the weighing unit 5.

[0067] It is understandable that before adding dairy products into the container 100, the container 100 can be dried by the drying unit 4 so that the weighing unit 5 can accurately weigh the net weight of the container 100 (or the container 100 containing the heating medium), and thus accurately obtain the first weighing data m1.

[0068] After the dairy product is added to the container 100, the drying unit 4 is used to dry the container 100 again, so that the weighing unit 5 can weigh the total weight of the container 100 and the dried dairy product, and thus accurately obtain the third weighing data m3.

[0069] For the above two weighing situations, in practical applications, the following operations can be used to further ensure the accuracy of the weighing results:

[0070] The heat drying mechanism 42 is first used to heat-dry the vessel 100, and then the vessel 100 that has completed the heat drying treatment is transferred to the dryer 43 for drying through the transfer unit 3. The drying time is set by the system. After the drying time is reached, the transfer unit 3 transfers the vessel 100 to the weighing unit 5, and the weighing unit 5 weighs the first data.

[0071] Next, the transfer unit 3 transfers the weighed vessel 100 to the heat drying mechanism 42, and the heat drying mechanism 42 performs heat drying treatment on the vessel 100 again. The heat-dried vessel 100 is then transferred to the dryer 43 for drying through the transfer unit 3. After the drying time is reached, the transfer unit 3 transfers the vessel 100 to the weighing unit 5, and the weighing unit 5 weighs the second data.

[0072] When the difference between the first data and the second data is less than the set value, it can be considered that the drying process of the vessel 100 meets the process requirements, otherwise the drying is repeated until the vessel 100 meets the constant weight requirement.

[0073] In some embodiments, Figure 1 and Figure 2 As shown, the drying unit 4 further includes a constant temperature water tank 41 ; the constant temperature water tank 41 is used to evaporate and dry the container 100 containing the dairy product, and the transfer unit 3 is used to transfer the evaporated container 100 to the heat drying mechanism 42 .

[0074] It is understandable that after adding dairy products to the container 100 and using the weighing unit 5 to weigh the total weight of the container 100 and the dairy products, it is necessary to use a constant temperature water tank 41, a heat drying mechanism 42 and a dryer 43 in sequence to dry the dairy products added to the container 100.

[0075] like Figure 5 As shown, the thermostatic water tank 41 includes a tank body 411 and a cover body 412. The cover body 412 is rotatably covered at the slot end of the tank body 411. The cover body 412 can be a transparent cover. The tank body 411 contains hot water of a preset temperature and is configured with a plurality of holes, each of which is used to store a vessel 100.

[0076] After placing the container 100 containing dairy products in the hole of the groove body 411, the cover body 412 can be placed on the groove end of the groove body 411, and then, the constant temperature water tank 41 is started to evaporate the container 100; after the evaporation time is reached, the transfer unit 3 transfers the container 100 that has completed the evaporation to the heat drying mechanism 42 and the dryer 43 in turn; at this time, the container 100 can be dried and weighed twice in succession according to the above operation. If the two weighing results are not within the allowable range, the drying and weighing operations of the container 100 are repeated until the weighing result reaches a constant weight.

[0077] In some embodiments, the total solids detection station for dairy products is also provided with a wiping unit; the wiping unit is arranged between the constant temperature water tank 41 and the heat drying mechanism 42; the transfer unit 3 is used to transfer the vessel 100 that has completed the evaporation treatment to the wiping unit, and the wiping unit is used to wipe the vessel 100, and the transfer unit 3 is also used to transfer the vessel 100 that has completed the wiping treatment to the heat drying mechanism 42.

[0078] It is understandable that after the vessel 100 is evaporated and dried by the constant temperature water tank 41 , water droplets are usually attached to the surface of the vessel 100 , and the water droplets attached to the surface of the vessel 100 can be wiped by the wiping unit.

[0079] The wiping unit can be a water-absorbing accessory such as a towel or a sponge. The wiping unit can be configured as a fixed setting. The transfer unit 3 drives the vessel 100 to move relative to the wiping unit, so that the wiping unit can be used to complete the wiping process of the vessel 100.

[0080] In some embodiments, Figure 1 and Figure 4 As shown, the heat drying mechanism 42 includes an electric blast oven 421 and a loading assembly 422; the loading assembly 422 is provided with a tray 300 for placing the vessel 100, and is used to transfer the tray 300 into the electric blast oven 421 or take it out from the electric blast oven 421; the electric blast oven 421 is used to perform heat drying treatment on the vessel 100 using hot air.

[0081] It is understandable that the electric hot air oven 421 can move along the first direction to reach a position corresponding to the loading assembly 422; the loading assembly 422 can drive the tray 300 to move along the second direction to transfer the tray 300 into the electric hot air oven 421 or take it out of the electric hot air oven 421.

[0082] In some examples, the electric hot air drying oven 421 includes a box body, a box door and a fan. The box body has a chamber and an air inlet and an air outlet connected to the chamber. An electric heating element is provided in the chamber, the fan is provided at the air inlet or the air outlet, and the box door is rotatably provided at an open end of one side of the box body.

[0083] There are a plurality of supporting parts arranged from top to bottom in the chamber, each supporting part is used to support a tray 300 , so that the electric hot air drying oven 421 can perform heat drying treatment on the vessels 100 supported by a plurality of trays 300 at one time.

[0084] In some examples, the loading component 422 is arranged opposite to the open end of the box body along the second direction, and the loading component 422 includes a lifting drive member and a horizontal drive member. The horizontal drive member is arranged on the lifting drive member. The horizontal drive member is used to support the tray 300 and drive the tray 300 to move along the second direction, thereby conveniently moving the tray 300 into the electric hot air oven 421 or taking it out of the electric hot air oven 421.

[0085] In some embodiments, Figure 1 and Figure 3As shown, the vessel cache unit 1 includes a first vessel cache rack 11 and a second vessel cache rack 12 ; the transfer unit 3 is used to pick up the vessel 100 from the first vessel cache rack 11 , and transfer the vessel 100 after the total solids detection to the second vessel cache rack 12 .

[0086] Specifically, the first vessel cache rack 11 and the second vessel cache rack 12 are arranged side by side and can adopt the same structure. Taking the first vessel cache rack 11 as an example, the first vessel cache rack 11 includes a frame body 111, and the frame body 111 is provided with a plurality of grooves 112. The plurality of grooves 112 are arranged in an array on a horizontal plane, and each groove 112 is used to place a vessel 100.

[0087] In some embodiments, Figure 1 and Figure 2 As shown, the sample pretreatment unit 2 includes an oscillator 23 and a capping machine 24; the transfer unit 3 is used to pick up the centrifuge tube 200 containing the dairy product and transfer the centrifuge tube 200 to the oscillator 23; the oscillator 23 is used to oscillate the centrifuge tube 200 so that the dairy product in the centrifuge tube 200 is evenly distributed; the transfer unit 3 is also used to transfer the centrifuge tube 200 after the oscillation treatment to the capping machine 24; the capping machine 24 is used to open the cap of the centrifuge tube 200 so that the transfer unit 3 can perform a sampling operation of the dairy product from the centrifuge tube 200.

[0088] Specifically, Figure 6 As shown, the oscillator 23 includes a vibration body 231, a test tube rack 232 and a limiting assembly 233. The test tube rack 232 is arranged on the vibration body 231. The test tube rack 232 is used to hold the centrifuge tube 200. The limiting assembly 233 has a first state connected to the vibration body 231 and a second state separated from the vibration body 231.

[0089] When the limit assembly 233 is in the first state, the vibration body 231 stops vibrating. The limit assembly 233 is used to limit the position of the vibration body 231 so that the transfer unit 3 picks up the centrifuge tube 200 from the test tube rack 232. When the limit assembly 233 is in the second state, the vibration body 231 starts vibrating.

[0090] The limiting assembly 233 includes at least two limiting units, which are arranged around the vibration body 231. Each limiting unit includes a lifting drive and a pressure plate. The lifting drive is connected to the pressure plate to drive the pressure plate to lift and lower, thereby contacting or separating from the top of the vibration body 231.

[0091] like Figure 7As shown, the capping machine 24 includes a lifting frame 241, a rotating driving member 242 and a clamping seat 243. The clamping seat 243 is used to clamp the centrifuge tube 200 and is arranged on one side of the lifting frame 241. The rotating driving member 242 is arranged on the lifting frame 241. The rotating driving member 242 is used to move downward under the drive of the lifting frame 241, and after being connected with the cap on the centrifuge tube 200, the cap can be separated from the centrifuge tube 200 by driving the cap to rotate.

[0092] Furthermore, the clamping seat 243 is movably disposed on one side of the lifting frame 241 to achieve proximity to or distance from the lifting frame 241; a movable chute 244 is provided on the lifting frame 241 so that one end of the chute 244 can move between a first position close to the execution end of the rotating drive member 242 and a second position away from the execution end of the rotating drive member 242.

[0093] When the rotary drive member 242 opens the cover of the centrifuge tube 200, the clamping seat 243 is close to the lifting frame 241 so that the centrifuge tube 200 is directly below the execution end of the rotary drive member 242. At this time, one end of the chute 244 is in the second position away from the execution end of the rotary drive member 242.

[0094] When the rotary drive member 242 completes the opening operation of the centrifuge tube 200, the clamping seat 243 moves away from the lifting frame 241. At this time, one end of the chute 244 is in the first position close to the execution end of the rotary drive member 242. The execution end of the rotary drive member 242 can release the cap into the chute 244, and the chute 244 transports the cap to the recovery station.

[0095] In some embodiments, Figure 1 and Figure 2 As shown, the sample pretreatment unit 2 also includes a loading cache rack 21 and a unloading cache rack 22 ; the transfer unit 3 is used to pick up the centrifuge tube 200 from the loading cache rack 21 , and transfer the centrifuge tube 200 after sampling to the unloading cache rack 22 .

[0096] Therein, a plurality of insertion holes are provided on the loading buffer rack 21 and the unloading buffer rack 22 , and each insertion hole is used for inserting a centrifuge tube 200 .

[0097] In some embodiments, Figure 1 and Figure 8 As shown, the transfer unit 3 includes a first transfer robot 31 and a second transfer robot 32; the first transfer robot 31 is used to pick up the centrifuge tube 200, and transfer the centrifuge tube 200 to the oscillator 23 and the capping machine 24 in sequence; the second transfer robot 32 is used to pick up the container 100, take samples from the centrifuge tube 200, transfer the sampled dairy product to the container 100, and control the container 100 to move between the drying unit 4 and the weighing unit 5.

[0098] Specifically, the first transfer robot 31 includes a first robotic arm 311 and a first clamp 312. The first robotic arm 311 can be a six-axis robotic arm. The first clamp 312 is arranged at the execution end of the first robotic arm 311. The first robotic arm 311 is used to control the posture of the first clamp 312 so that the first clamp 312 clamps the centrifuge tube 200, and then transfers the centrifuge tube 200 to the oscillator 23 and the capping machine 24 in sequence.

[0099] The first transfer robot 31 and the vessel cache unit 1 are arranged side by side, and the first transfer robot 31 is configured to perform material picking operations according to the incoming material information sent by the scheduling system.
