[0057] In one specific embodiment, the milk tablet adding assembly 222 further comprises a pipe, the outer diameter of the pipe is adapted to the inner diameter of the milk tablet hole, and the pipe is clamped in the milk tablet hole. In one embodiment, the middle part of the pipe in the height direction is provided with a clamping table, which abuts against the top surface of the support table 223, for limiting the position of the pipe. The side wall of the pipe close to the milk tablet storage cylinder 2221 is provided with a milk tablet inlet, which corresponds to the opening on the milk tablet storage cylinder 2221, i.e. the center line of the milk tablet inlet is collinear with the center line of the opening. The first control member controls the fourth driving mechanism 2222 to drive the milk tablets to leave the milk tablet storage cylinder 2221 through the opening and enter the pipe through the milk tablet inlet, and then fall into the digestive tube under the guidance of the pipe, preventing the milk tablets from deviating during falling.

[0058] In one embodiment, the milk tablet storage cylinder 2221 and the fourth driving mechanism 2222 are both multiple, such as 2, 3, 5, etc. The fourth driving mechanism 2222 drives the milk tablets in the corresponding milk tablet storage cylinder 2221 to fall into the digestive tube through the milk tablet hole, which can continuously add milk tablets into the digestive tube arranged in the digestive tube clamping hole, avoiding long-term interruption.

[0059] In the case that the pipeline is clamped in the milk tablet through hole, a plurality of milk tablet inlets are arranged on the pipeline, the number of the milk tablet inlets is greater than or equal to the number of the milk tablet storage barrels 2221, each milk tablet inlet corresponds to the opening on the milk tablet storage barrel 2221, and the milk tablets in different milk tablet storage barrels 2221 can enter the pipeline through the corresponding milk tablet inlets and fall into the digestive tube arranged in the digestive tube clamping hole under the guidance of the pipeline.

[0060] The milk tablet storage barrel 2221 comprises a fixed barrel, a sealing barrel and an inner barrel. The fixed barrel is installed on the support table 223, the sealing barrel is inserted into the fixed barrel, and the inner barrel is inserted into the sealing barrel. The lower parts of the fixed barrel, the sealing barrel and the inner barrel are all provided with openings, and the third driving end can drive the milk tablets to leave the milk tablet storage barrel 2221 through the openings in sequence. Specifically, the sealing barrel and the inner barrel are fixed on the support table 223 through the fixed barrel, and the sealing barrel is arranged between the inner barrel and the fixed barrel, so as to prevent the debris of the milk tablets from entering the fixed barrel. In the case that the milk tablets need to be cleaned and stored, the sealing barrel and the inner barrel can be taken out alone or simultaneously, so as to facilitate repeated use and maintenance.

[0061] The embodiment of the utility model not only can detect the protein in the tablet milk tablet, but also can detect the liquid milk product, so as to meet different categories of protein detection.

[0062] In another embodiment, the protein detection solution can also include a liquid milk product and a digestive agent. The protein pretreatment device 20 can include a liquid milk product adder, a digestive tube support frame and a digestive agent adder arranged on the workbench 10. The liquid milk product adder and the digestive agent adder are respectively located on both sides of the digestive tube support frame. In a specific embodiment, the digestive agent adder is arranged above the digestive tube support frame, and the liquid milk product is arranged on one side of the digestive tube support frame. The digestive agent adder is used to add a digestive agent to the digestive tube located in the digestive tube support frame. The liquid milk product adder is used to add a liquid milk product to the digestive tube located in the digestive tube support frame.

[0063] It should be noted that the digestive tube support frame in the embodiment is equivalent to the first digestive frame in the above-mentioned embodiment, and the digestive agent adder is equivalent to the reagent adding assembly 221 in the above-mentioned embodiment.

[0064] In the actual operation process, the manipulator can transfer the digestive tube from the digestive tube placing frame 11 to the digestive tube support frame, and the manipulator 50 can also transfer the milk product in the liquid milk product adder to the digestive tube located in the digestive tube support frame.

[0065] In one embodiment, the liquid milk product adding device comprises a first pipette. The workbench 10 is provided with a pipette placing mechanism 140, which is provided with a tip box and a pipette fixing member. The first pipette is hung on the pipette fixing member, and a plurality of tips are placed in the tip box to adapt to different needs. The first pipette is used to suck the liquid milk product in the centrifugal tube and add it into the digestion tube on the digestion tube support frame. In actual operation, the robot moves the digestion tube from the digestion tube placing frame 11 to the digestion tube support frame. The robot 50 clamps the first pipette on the pipette placing mechanism 140 and controls the first pipette to suck the liquid milk product and add the liquid milk product in the first pipette into the digestion tube on the digestion tube support frame.

[0066] The liquid milk product adding device can also comprise a centrifugal tube placing frame 13 and a shaking mechanism 70 arranged on the workbench 10. The centrifugal tube placing frame 13 and the shaking mechanism 70 are arranged on opposite sides of the robot 50 to shorten the distance between them and the moving stroke of the robot 50, thereby improving efficiency. The centrifugal tube placing frame 13 and the shaking mechanism 70 can be arranged on opposite sides of the robot 50 or adjacent sides of the robot 50. The centrifugal tube placing frame 13 is used to place the centrifugal tube, which is used to hold the liquid milk product, such as milk. Specifically, the centrifugal tube placing frame 13 is provided with a centrifugal tube clamping hole. The centrifugal tube is inserted through the centrifugal tube clamping hole and clamped to the centrifugal tube placing frame 13. The shaking mechanism 70 is used to shake the liquid milk product in the centrifugal tube after the robot 50 transports the centrifugal tube from the centrifugal tube placing frame 13 to prevent stratification and affect subsequent detection.

[0067] In one embodiment, the shaking mechanism 70 comprises a gripper, a second control member, and a rotating member. The gripper is connected to the rotating member. The gripper is used to clamp the centrifugal tube, and the rotating member and the gripper are electrically connected to the second control member. When the robot 50 transports the centrifugal tube from the centrifugal tube placing frame 13, the second control member controls the gripper to clamp the centrifugal tube. The second control member controls the rotating member to rotate the gripper and the centrifugal tube, thereby shaking the liquid milk product in the centrifugal tube.

[0068] The liquid milk product adding device also comprises a cap screwing mechanism 80 arranged on the workbench 10. The cap screwing mechanism 80 is arranged adjacent to the shaking mechanism 70. The cap screwing mechanism 80 is used to unscrew the bottle plug of the centrifugal tube transported by the robot 50 from the shaking mechanism 70. By arranging the cap screwing mechanism adjacent to the shaking mechanism, the robot can move more conveniently. The distance between them is short, which improves the moving efficiency. At the same time, it can also prevent the milk product from precipitating or stratifying again after shaking.

[0069] After the shaking mechanism 70 shakes, the mechanical arm 50 clamps the centrifugal tube after shaking and places it in the cap screwing mechanism 80. The centrifugal tube includes a main body and a bottle plug. The cap screwing mechanism 80 includes a first clamping piece for clamping the main body and a second clamping piece for clamping the bottle plug. The first clamping piece or the second clamping piece is driven to rotate, or the first clamping piece and the second clamping piece are driven to rotate in opposite directions around the same axis, so that the main body and the bottle plug of the centrifugal tube are separated, thereby unscrewing the bottle plug of the centrifugal tube, and facilitating the first pipette to suck the liquid dairy product in the centrifugal tube. In the case where the bottle plug and the main body are cooperated by plugging and unplugging, the first clamping piece is driven to move away from the bottle plug, or the second clamping piece is driven to move away from the main body, so that the main body and the bottle plug of the centrifugal tube are separated.

[0070] The liquid dairy product adder further includes a first weighing mechanism 90 adjacent to the cap screwing mechanism 80 and located on the opposite side of the cap screwing mechanism 80. The first weighing mechanism 90 is used to obtain the weight of the liquid dairy product transferred from the centrifugal tube to the digestion tube located in the digestion tube support frame.

[0071] The workbench 10 is provided with a container placing rack 14 adjacent to the first weighing mechanism 90. The container placing rack 14 is used to place a container for containing the liquid dairy product, facilitating the weighing of the first weighing mechanism 90. The first weighing mechanism 90 is used to weigh the empty container and the container containing the liquid dairy product. The container placing rack 14 can also place the centrifugal tube. The centrifugal tube opened by the mechanical arm through the cap screwing mechanism 80 is transferred to the container placing rack 14, shortening the distance between the centrifugal tube and the digestion tube support frame and improving the adding efficiency. Further, the mechanical arm 50 clamps the digestion tube added with the liquid dairy product and moves it to the container, and the mechanical arm 50 clamps the container in which the digestion tube is placed and moves it to the first weighing mechanism 90 for weighing, obtaining the weight of the liquid dairy product in the digestion tube. It should be noted that the weight of the empty container and the empty digestion tube is measured in advance, and can also be measured before the experiment starts. The weight of the liquid dairy product in the digestion tube is obtained by calculation. It can be understood that the addition of the first weighing mechanism 90 and the first pipette can be alternately performed until the target requirement is reached. After the liquid dairy product addition measurement is completed, it can be moved to the container placing rack 14 by the mechanical arm 50 for storage, or it can be directly moved to the digestion tube support frame and the digestion agent is added to the digestion tube by the digestion agent adder.

[0072] In one embodiment, the container includes a beaker, which is placed on the container rack 14. The mechanical arm 50 holds the beaker and places it on the first weighing mechanism 90 to obtain the weight of the empty beaker; the mechanical arm 50 holds the centrifuge tube and pours the liquid milk product in the centrifuge tube into the beaker to obtain the total weight of the beaker and the liquid milk product contained therein. The mechanical arm 50 holds the first pipette, sucks the liquid milk product in the beaker, adds it to the digestion tube of the digestion tube support rack, and determines the added amount by weight loss, i.e., the difference between the weights of two adjacent times is the added amount. After completion, the beaker can be stored on the container rack 14 by the mechanical arm 50. After the liquid milk product addition measurement is completed, the digestion agent is added to the digestion tube by the digestion agent adder, and the same as above, which will not be repeated here.

[0073] The first weighing mechanism 90 can be a first balance, and a balance platform is provided on the workbench 10, and the first balance is placed on the balance platform to avoid inaccurate weighing due to vibration. At the same time, the outer periphery of the first balance is provided with a balance door to isolate the influence of the outside on the first balance. The first balance can be zeroed before weighing to improve accuracy.

[0074] In order to identify the type of liquid milk product, the liquid milk product adder further includes a code scanning mechanism 60 provided on the workbench 10, which is used to scan and identify the centrifuge tube when the centrifuge tube is transported by the mechanical arm 50 to obtain the information of the liquid milk product in the centrifuge tube. Specifically, each centrifuge tube is provided with a label, and the label includes the information of the liquid milk product in the centrifuge tube. The code scanning mechanism 60 scans and identifies the label of the centrifuge tube to obtain the information of the liquid milk in the centrifuge tube, which is convenient for subsequent operation and avoids operation errors.
