[0002] In the field of criminal investigation, biological fluids such as saliva, semen, and blood contain human DNA information, which can be used as evidence to solve a case. After the biological fluid is extracted at the crime scene, it will be placed in a test tube for storage. The biological fluid in the test tube cannot be directly tested and used, and needs to be further purified. Generally, a portion of the biological fluid is taken from the test tube manually, dripped into a blank test tube, and a special reagent is dripped into the test tube. Then the reagent and the biological fluid are fully mixed and evenly mixed. After the mixing is completed, it is placed in a centrifuge for the first centrifugal treatment. After the treatment is completed, the liquid in the test tube will be stratified, and then the supernatant is manually extracted and placed in a new blank test tube. The supernatant is then centrifuged for a second time. After the treatment is completed, the upper layer of liquid can be sucked and dripped into a glass bottle for storage. This is the purified liquid we finally get.

[0019] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] like Figure 1-Figure 2 As shown, a preferred embodiment of the present invention proposes a fully automatic intelligent physical and chemical testing workstation, which mainly includes modules such as a test tube rotating module 1, a reagent rotating module 2, a lifting mechanism 3, a reagent bottle cap screwing mechanism 5, a coding mechanism 6, a capping mechanism 7 and a test tube cap screwing mechanism 8.

[0021] The reagent bottle cap screwing mechanism 5, the coding mechanism 6, the capping mechanism 7 and the test tube cap screwing mechanism 8 are respectively located in the circumferential direction of the test tube rotating module 1. The reagent bottle cap screwing mechanism 5 is used to unscrew the bottle cap of the corresponding reagent bottle located on the reagent rotating module 2, the coding mechanism 6 is used to spray the code on the glass bottle containing the purified liquid, the capping mechanism 7 is used to press the metal seal onto the glass bottle, and the test tube cap screwing mechanism 8 is used to unscrew the tube cap of the test tube located on the test tube rotating module 1.

[0022] Specifically, refer to Figure 1 The test tube rotating module 1 is used to transfer the test tube to the positions of the test tube cover screwing mechanism 8, the capping mechanism 7, the coding mechanism 6, and the reagent bottle cover screwing mechanism 5. The test tube rotating module 1 is used to connect the various workstations to improve the work efficiency.

[0023] like Figure 4-Figure 6As shown, the test tube rotating module 1 is mainly composed of a motor 15, a rotating table 11, a clamping mechanism 12, a pushing mechanism 16 and a loosening mechanism 17, wherein the rotating table 11 is circular, which is installed on a base 13 and can rotate relative to the base 13, and the motor 15 is installed at the bottom of the rotating table 11 for driving the rotating table 11 to rotate.

[0024] There are a plurality of grooves in the circumferential direction of the rotating table 11, each groove corresponding to a clamping position. The number of clamping mechanisms 12 is the same as the number of clamping positions, and the clamping mechanisms 12 are installed in the grooves. The pushing mechanism 16 is located above the rotating table 11 and corresponds to one of the clamping mechanisms 12, and is used to control the clamping mechanism 12 to clamp the test tube so that the test tube cover can be screwed off the test tube.

[0025] The plurality of grooves are evenly distributed along the circumferential direction of the rotating table 11. The clamping mechanism 12 has a plurality of different specifications, respectively used to clamp test tubes of different diameters. Each diameter of the test tube corresponds to two clamping mechanisms 12, and the two clamping mechanisms 12 are symmetrically distributed, and the rotation angle between them is 180°. In this embodiment, there are three types of clamping mechanisms 12, corresponding to three diameters of test tubes.

[0026] like Figure 6 As shown, Figure 6 The protective cover 14 and a second clamping block 122 are removed. The clamping mechanism 12 is mainly composed of a first clamping block 121, a second clamping block 122, a fixed block 123 and a connecting rod 124, wherein the first clamping block 121 and the fixed block 123 are fixedly installed in the installation groove, the first clamping block 121 is located at the edge of the rotating table 11, and the first clamping block 121 and the fixed block 123 are connected by a connecting rod 124. The second clamping block 122 is located above the fixed block 123, and the connecting rod 124 is connected to the second clamping block 122 through an interlaced connection. Two connecting rods 124 are provided, corresponding to the two ends of the first clamping block 121 and the fixed block 123 respectively. A spring is provided between the second clamping block 122 and the fixed block 123, and the spring is sleeved on the connecting rod 124. The spring will apply a pre-tightening force to the second clamping block 122, so that the first clamping block 121 and the second clamping block 122 are closed.

[0027] Semicircular positioning grooves are formed on the opposite sides of the first clamping block 121 and the second clamping block 122 for positioning the test tube. Under the action of the spring, the first clamping block 121 and the second clamping block 122 clamp the test tube.

[0028] The diameter of the positioning groove is matched to the diameter of the test tube, and the diameter of the positioning groove in the clamping mechanism 12 corresponding to different test tubes is also different.

[0029] like Figure 6As shown, the release mechanism 17 is located below the rotating table 11, and is composed of a release plate 171 and a release cylinder (not shown in the figure). The release cylinder is horizontally fixed to the bottom of the base 13, and the release plate 171 is connected to the output end of the release cylinder. The release plate 171 is controlled to move horizontally by the release cylinder.

[0030] The second clamping block 122 can move horizontally relative to the rotating table 11. A portion of the bottom of the second clamping block 122 protrudes downward and passes through the rotating table 11 to extend to the moving path of the release plate 171. There is a partial notch on the rotating table 11 so that the protrusion at the bottom of the second clamping block 122 can move horizontally.

[0031] In the initial state, the second clamp 122 will close with the first clamp 121 under the action of the spring. When the test tube needs to be loaded, the release cylinder will control the release plate 171 to move toward the center of the rotating table 11. The release plate 171 has two blocking parts 1711 corresponding to the protrusions at the bottom of the second clamp 122. During the movement of the release plate 171, the blocking parts 1711 will approach the protrusions at the bottom of the second clamp 122 and pull the second clamp 122 to move, overcoming the preload force of the spring, so that the second clamp 122 and the first clamp 121 release the test tube, so that the test tube can be taken and placed. On the contrary, the release cylinder controls the release plate 171 to move in the opposite direction, and the blocking parts 1711 gradually move away from the protrusions at the bottom of the second clamp 122, so that the second clamp 122 returns to its original position under the action of the spring and cooperates with the first clamp 121 to clamp the test tube.

[0032] Then the rotating platform 11 will rotate 180°. During the rotation of the rotating platform 11 , the clamping mechanism 12 will rotate together with the rotating platform 11 , while other structures will not rotate.

[0033] like Figure 6 As shown, the pushing mechanism 16 is located above the rotating table 11 and is fixedly connected to the base 13. The pushing mechanism 16 is mainly composed of a cylinder fixing seat 161, a pushing cylinder 162, a guide rod 165, a sliding block 163 and a pushing block 164, wherein the cylinder fixing seat 161 is connected to the base 13 through a connecting piece, the pushing cylinder 162 is horizontally fixedly installed on the cylinder fixing seat 161, the output end of the pushing cylinder 162 is connected to the sliding block 163, and a guide rod 165 is respectively provided at both ends of the sliding block 163, and the guide rod 165 is interlaced with the sliding block 163, one end of the guide rod 165 is fixedly connected to the pushing block 164, and the other end is interlaced with the cylinder fixing seat 161. A spring is provided between the sliding block 163 and the pushing block 164, and the spring is sleeved on the guide rod 165. The spring plays a buffering role, and the guide rod 165 can play a guiding role for the spring.

[0034] In other technical solutions, the spring may also be arranged on the guide rod 165 , directly between the sliding block 163 and the pushing block 164 .

[0035] When the clamping mechanism 12 holding the test tube rotates to the position of the pushing mechanism 16, the pushing cylinder 162 controls the sliding block 163 to move relative to the guide rod 165, and the thrust of the sliding block 163 is applied to the spring, and the spring transmits the thrust to the pushing block 164, pushing the pushing block 164 to move. The pushing block 164 gradually approaches the second clamping block 122 and tightly abuts against the second clamping block 122, so that the second clamping block 122 cooperates with the first clamping block 121 to clamp the test tube, so as to prevent the test tube from rotating during the process of screwing the test tube cover. When the pushing block 164 abuts against the second clamping block 122, the spring will be compressed by force, playing a buffering role, preventing the second clamping block 122 from being damaged due to excessive force.

[0036] In order to protect the pushing mechanism 16, a protective cover 14 is provided above the pushing mechanism 16 to play a protective role. The protective cover 14 has an outlet to facilitate the movement of the push block 164 in and out.

[0037] refer to Figure 2 , Figure 4 , Figure 8 The reagent rotating module 2 is located directly below the test tube rotating module 1. The reagent rotating module 2 mainly includes a rotating disk 22, a stand 21 and a driving mechanism, wherein the rotating disk 22 is rotatably mounted on the stand 21, and the driving mechanism adopts a rotating motor 15, which is mounted on the stand 21 and is drivingly connected to the bottom of the rotating disk 22, and is used to drive the rotating disk 22 to rotate.

[0038] The rotating disk 22 is concentric with the rotating platform 11 , but the diameter of the rotating disk 22 is larger than the diameter of the rotating platform 11 , so that the reagent bottle can avoid the rotating platform 11 during the upward lifting process.

[0039] A plurality of grooves are provided on the rotating disk 22 to form a placement position for placing reagent bottles. The grooves have a certain depth, and the reagent bottles can be limited to prevent them from tipping over. There are many types of reagents, so a plurality of different reagents can be placed on a rotating disk 22. According to the demand, the motor 15 will control the corresponding reagent bottle to rotate to the corresponding position, waiting for the reagent to be taken.

[0040] like Figure 2 As shown, a lifting mechanism 3 is provided at the position where the reagent is to be taken (i.e., next to the reagent bottle cap screwing mechanism 5), which is used to lift the reagent bottle upwards so as to take the reagent. Two lifting mechanisms 3 can also be provided, which can be adjusted according to needs.

[0041] The lifting mechanism 3 is composed of a lifting linear module 31, a lifting plate 32, and a bracket 33, wherein the lifting linear module 31 is vertically arranged to control the lifting of the bracket 33. The lifting plate 32 is fixedly mounted on the slide of the lifting linear module 31, and the bracket 33 is fixedly mounted on the lifting plate 32, and the lifting linear module 31 is used to control the bracket 33 to move up and down.

[0042] The center of the bracket 33 is circular and used to support the reagent bottle. The circumference of the circular part has a plurality of limiters 331 that are bent and extended vertically upwards, which are used to surround the reagent bottle to prevent the reagent bottle from tipping over when lifted.

[0043] refer to Figure 8 At the bottom of each groove of the rotating table 11, there is an avoidance hole 221 whose shape is adapted to the shape of the bracket 33. At the same time, on the outer circumferential surface of the rotating disk 22, there is a notch at the position corresponding to each groove so that the bracket 33 can avoid it when it moves up and down.

[0044] When the corresponding reagent bottle on the rotating disk 22 rotates to the position of the lifting mechanism 3, the lifting linear module 31 will control the bracket 33 to move upward, the bracket 33 will pass through the avoidance hole 221 upward, and lift the reagent bottle upward to the height of the test tube rotating module 1, waiting for the reagent to be absorbed.

[0045] In this embodiment, the rotating table 11 rotates in a counterclockwise direction. When the test tube is placed on the rotating table 11 and clamped, the rotating table 11 rotates the test tube to the position of the test tube cover screwing mechanism 8, and the test tube cover screwing mechanism 8 screws the cover on the test tube open.

[0046] like Figure 1 As shown, two clamping mechanisms 4 are arranged above the reagent bottle rotating module, and the two clamping mechanisms 4 are arranged opposite to each other.

[0047] like Fig. 9 As shown, the clamping mechanism 4 is composed of a clamping cylinder 41 and a clamping block 42. The clamping block 42 is connected to the output end of the clamping cylinder 41. There are V-shaped limiting grooves on the opposite sides of the two clamping blocks 42 so that reagent bottles with different diameters can be clamped.

[0048] like Fig.10 As shown, a protective cover 14 is provided on the outer sides of the two clamping mechanisms 4 , and a through hole is provided in the middle of the protective cover 14 , which can limit the position of the reagent bottle and protect the clamping cylinder 41 .

[0049] When reagent needs to be added, the rotating table 11 will rotate the test tube to the position of the reagent bottle cap screwing mechanism 5. Before adding the reagent, the corresponding reagent will be selected first, and the rotating disk 22 will rotate the corresponding reagent to the position of the reagent bottle cap screwing mechanism 5. The lifting mechanism 3 is located on one side of the reagent bottle cap screwing mechanism 5, and the lifting mechanism 3 will lift the reagent bottle upward. The reagent bottle arrives between the two clamping mechanisms 4, and then the two clamping mechanisms 4 will clamp the body of the reagent bottle to prevent the bottle body from rotating when the bottle cap is screwed. The reagent bottle cap screwing mechanism 5 will control the clamping of the reagent bottle cap, and then rotate to screw the bottle cap off, wait for the reagent to be taken, and then absorb the reagent and add it dropwise into the test tube. After the addition is completed, the test tube cover and the reagent bottle cap will be screwed on again.

[0050] like Figure 1 , Figure 3 As shown, the coding mechanism 6 and the capping mechanism 7 are sequentially arranged between the reagent bottle cap screwing mechanism 5 and the test tube cap screwing mechanism 8, and the coding mechanism 6 is used to spray a two-dimensional code or a barcode containing the extract information onto the glass bottle. The glass bottle can be a wide-mouth bottle or a narrow-mouth bottle, and the bottle contains the extract after physical and chemical treatment. The capping mechanism 7 is used to press the bottle cap onto the glass bottle.

[0051] The structure of the reagent bottle cap screwing mechanism 5 is similar to that of the test tube cap screwing mechanism 8, except that the structure of the cap screwing assembly is slightly different. The clamping claws in the cap screwing assembly are larger to match the size of the bottle cap on the reagent bottle.

[0052] After completing the above operations, the test tube rotating module 1 will transfer the glass bottle to the bottom of the capping mechanism 7, and the capping mechanism 7 will press the sealing metal part onto the bottle cap. Then the glass bottle will be transferred to the location of the coding mechanism 6, and the coding mechanism 6 will spray a QR code or barcode on the bottle. Finally, the glass bottle is removed and placed in the corresponding carrier, and all the processes are completed.

[0053] The above technical solutions only reflect the preferred technical solutions of the technical solutions of the present invention. Some changes that may be made to certain parts thereof by technicians in this technical field all reflect the principles of the present invention and fall within the protection scope of the present invention.
