[0051] The utility model discloses a sampling device, which includes a frame 40, a transmission component 30, a clamping jaw component 20, a cup supply component 60, a sampler 50 and a sealing mechanism 10 sequentially arranged above the transmission component 30; the transmission component is arranged at the bottom of the frame 40; the clamping jaw component 20 is arranged on the transmission component 30, and the transmission component 30 is used to drive the clamping jaw component 20 to move back and forth between the cup supply component 60, the sampler 50 and the sealing mechanism 10; the cup supply component 60 is used to place a sampling cup 80 on the clamping jaw component 20, the sampler 50 is used to place a sample in the sampling cup 80, and the sealing mechanism 10 is used to seal the cup mouth of the sampling cup 80.

[0052] In one embodiment, the frame 40 is made of a metal material with high strength as a load-bearing component. Figure 1 In this embodiment, the frame 40 can be a rectangular parallelepiped structure. The frame 40 is divided into two layers, each layer having a shelf for mounting support. The conveying assembly 30 and the gripper assembly 20 are mounted on the bottom shelf of the frame 40 to facilitate conveying the sampling cup 80 at the bottom of the frame 40. The cup supply assembly 60, the sampler 50, and the sealing mechanism 10 are mounted on the upper shelf of the frame 40, thereby facilitating top-down access to the sampling cup 80 and improving ease of use.

[0053] The cup supply assembly 60, the sampler 50 and the sealing mechanism 10 are all spaced apart on the top of the frame 40; the conveying direction of the conveying assembly 30 is consistent with the arrangement direction of the cup supply assembly 60, the sampler 50 and the sealing mechanism 10. Figure 1 When the cup assembly 60, the sampler 50 and the sealing mechanism 10 are arranged in a straight line, the conveying assembly 30 is conveyed along a straight line. When they are arranged in an L shape, the conveying assembly 30 is conveyed along the L shape accordingly.

[0054] During sampling, the conveyor assembly 30 first moves the gripper assembly 20 to the bottom of the cup supply assembly 60. The cup supply assembly 60 includes a long, cylindrical storage box 61 for storing sampling cups 80. The bottom of the storage box 61 has a cup outlet 62, and the top shelf of the frame 40 has a through-hole 41. During installation, the cup outlet 62 is aligned with the through-hole 41. The cup supply assembly 60 then deposits a clean, empty cup from the outlet 62 onto the gripper assembly 20 at the bottom, where the clean sampling cup 80 is placed with its mouth facing upward.

[0055] The conveyor assembly 30 transports the gripper assembly 20, containing the empty cup, to the bottom of the sampler 50. The sampler 50 is a tubular structure with a sampling port 42 disposed on the top shelf of the frame 40. One end of the sampler 50 is connected to the sampling port 42, and the other end is connected to an external feeding device. The feeding device feeds the sample material from the sampling port 42 into the empty cup at the bottom.

[0056] The conveying component 30 continues to convey the sampling cup 80 containing the sample to the bottom of the sealing mechanism 10. The sealing mechanism 10 can seal the cup mouth of the sampling cup 80 by heat sealing, gluing, etc.

[0057] In addition, in one embodiment, the sampling device may further include a collection chamber 70, which is disposed at the downstream end of the transmission component 30. Figure 1 and Figure 3 When the conveying assembly 30 conveys the sampling cup 80 from left to right, the right side of the conveying assembly 30 is its downstream. The collecting chamber 70 is installed on the right side of the conveying assembly 30.

[0058] The collection chamber 70 has a collection window 71 that faces upward. The conveying assembly 30 conveys the clamping assembly 20 to above the collection window 71 . The clamping assembly 20 releases the sampling cup 80 , thereby placing the sealed sampling cup 80 into the collection chamber 70 .

[0059] The collection chamber 70 is detachably connected. When the collection chamber 70 is full of the sampling cups 80 , the sampling cups 80 in the collection chamber 70 can be transferred by an on-site operator.

[0060] The conveyor assembly 30 of this utility model is used to transport the sampling cup 80 back and forth between the cup supply assembly 60, the sampler 50, and the sealing mechanism 10. The cup supply mechanism automatically supplies the sampling cup 80, the sampler 50 automatically adds the sample to the sampling cup 80, and the sealing mechanism 10 seals the cup. This automatically seals the sampling cup 80 during the sampling process, preventing the sample from being disturbed by the external environment after sampling. This improves stability and product quality.

[0061] In one embodiment, please refer to Figure 2and Figure 4 The sealing mechanism 10 includes a storage tank 11, a material taking component 12, and a heat sealing component 13. The storage tank 11 is arranged above the conveying component 30, and the storage tank 11 is used to store the sealing film; the material taking component 12 is movably arranged at the bottom of the storage tank 11; the heat sealing component 13 is arranged on one side of the material taking component 12, and the material taking component 12 is used to grab the sealing film and place the sealing film on the bottom of the heat sealing component 13, and the heat sealing component 13 is used to seal the sealing film on the cup mouth of the sampling cup 80.

[0062] In this embodiment, heat sealing is used as an example to illustrate that a sealing film having the same size as the sampling cup 80 is stored in the storage tank 11. The top of the storage tank 11 can be open to facilitate the operator to add sealing film therein.

[0063] Please refer to Figure 6 The bottom of the storage tank 11 has a film outlet 111, and the sealing film falls to the film outlet 111 under the action of gravity. The size of the film outlet 111 is slightly smaller than the sealing film to limit the sealing film in the storage tank 11.

[0064] When sealing the film, the material taking component 12 moves to the bottom of the storage tank 11 and absorbs the sealing film at the bottom through the film outlet 111. The sealing film is made of flexible material, so the material taking component 12 can take the sealing film out from the film outlet 111.

[0065] The material taking component 12 moves the sealing film to the bottom of the heat sealing component 13 , and the heat sealing component 13 heats and welds the sealing film to the cup opening of the sampling cup 80 .

[0066] For details, please refer to Figure 6 A limit opening 43 is also provided on the top layer plate of the frame 40. The heat sealing assembly 13 includes a heat sealing plate 132 and a second driving member 131. The second driving member 131 can be a driving cylinder.

[0067] The second driving member 131 can be installed on one side of the stop opening 43. The shape and size of the heat sealing plate 132 are consistent with the shape and size of the sealing film and the cup opening of the sampling cup 80. The driving end of the second driving member 131 extends to the top of the stop opening 43 and is connected to the heat sealing plate 132.

[0068] The material collection component 12 places the sealing film in the limiting opening 43. After the heat sealing plate 132 is heated, it descends through the second driving member 131. The heat sealing plate 132 passes through the limiting opening 43 and abuts against the sealing film until the sealing film is pressed tightly against the cup mouth of the sampling cup 80 at the bottom. The sealing film and the cup mouth of the sampling cup 80 are melted together by heating to achieve sealing of the sampling cup 80.

[0069] The limiting opening 43 is used to position the heat sealing plate 132 , thereby improving the accuracy of the heat sealing plate 132 and avoiding potential safety hazards caused by position deviation and failure to accurately land on the sampling cup 80 .

[0070] It should be noted that the size of the limiting opening 43 can be slightly smaller than the sealing film, so that when the material removal component 12 places the sealing film in the limiting opening 43, the limiting opening 43 can limit the sealing film and prevent it from falling out of the limiting opening 43.

[0071] In another embodiment, please refer to Figure 2 and Figure 4 The material picking component 12 includes a first rotating member 121, a second rotating member 122 and a suction cup 123, wherein the first rotating member 121 is arranged below the storage tank 11; the second rotating member 122 is connected to the first rotating member 121 through a connecting rod 125; the suction cup 123 is arranged on the second rotating member 122, wherein the rotating axes of the first rotating member 121 and the second rotating member 122 are arranged perpendicularly, the second rotating member 122 is used to adjust the adsorption direction of the suction cup 123, and the first rotating member 121 is used to adjust the adsorption position of the suction cup 123.

[0072] The suction cup 123 is connected to an external blower device through a pipeline, and negative pressure is formed on the suction cup 123 to produce an adsorption effect to absorb the sealing film.

[0073] The first rotating member 121 can be a rotating cylinder or a motor, etc. The rotating axis of the first rotating member 121 is perpendicular to the top layer of the frame 40, thereby driving the second rotating member 122 and the suction cup 123 to rotate left and right to adjust the suction cup 123 to swing back and forth between the storage tank 11 and the heat sealing plate 132.

[0074] The rotation axis of the second rotating member 122 remains parallel to the top shelf of the frame 40, thereby driving the suction cup 123 to rotate up and down to adjust the suction direction of the suction cup 123. When it rotates to the bottom of the storage tank 11, the suction direction of the suction cup 123 is driven upward, aligned with the film outlet 111 at the bottom of the storage tank 11, and sucking the sealing film therein. When it rotates to the bottom of the heat sealing assembly 13, the suction cup 123 is driven downward to place the sealing film on the stop opening 43.

[0075] In another embodiment, the material picking assembly 12 further includes a first driving member 124 , the first driving member 124 is disposed on the second rotating member 122 , the suction cup 123 is disposed on the first driving member 124 , and the first driving member 124 is used to drive the suction cup 123 to extend and retract.

[0076] The first driving member 124 can be a cylinder installed between the suction cup 123 and the second rotating member 122. When the second rotating member 122 rotates, it drives the first driving member 124 and the suction cup 123 to rotate synchronously.

[0077] The suction cup 123 is mounted on the driving end of the first driving member 124 . When the cylinder of the first driving member 124 moves in a telescopic manner, the suction cup 123 is driven to move in a synchronous telescopic manner, thereby completing the contact with the sealing film in the storage tank 11 for adsorption.

[0078] In another embodiment, please refer to Figure 1 、 Figure 3 and Figure 5 The clamping jaw assembly 20 includes a third driving member 21, a first clamping plate 22 and a second clamping plate 23. The third driving member 21 is arranged on the transmission assembly; the first clamping plate 22 and the second clamping plate 23 are arranged opposite to each other, and the third driving member 21 is connected to the first clamping plate 22 and the second clamping plate 23 respectively. The third driving member 21 is used to drive the first clamping plate 22 and the second clamping plate 23 to move toward or away from each other; wherein, the first clamping plate 22 has a first limiting groove, and the second clamping plate 23 has a second limiting groove. When the first clamping plate 22 and the second clamping plate 23 move toward each other until they abut, the first limiting groove and the second limiting groove are docked to form a notch for supporting the sampling cup 80.

[0079] The third driving member 21 can be a bidirectional driving cylinder, with both ends connected to the first clamping plate 22 and the second clamping plate 23 respectively, to drive the first clamping plate 22 and the second clamping plate 23 to move toward or away from each other.

[0080] Both the first and second limiting grooves are semicircular groove-shaped structures, have the same diameter, and are positioned in corresponding positions. Therefore, when the first and second clamping plates 22 and 23 move toward each other until they abut, the first and second limiting grooves join to form a circular notch. The diameter of this notch is smaller than the maximum diameter of the sampling cup 80, allowing the sampling cup 80 to be locked into the notch when it is dropped from the cup supply assembly 60.

[0081] When the sampling cup 80 needs to be put down, the third driving member 21 drives the first clamping plate 22 and the second clamping plate 23 to move away from each other, thereby releasing the sampling cup 80 .

[0082] In another embodiment, in order to improve the sampling efficiency, multiple groups of clamping jaw assemblies 20 are installed on the transmission assembly 30. In this embodiment, three groups of clamping jaw assemblies 20 are provided as an example for explanation. Figure 1 , from left to right are the first clamping jaw assembly 20 , the second clamping jaw assembly 20 and the third clamping jaw assembly 20 .

[0083] During sampling, the initial position of the first jaw assembly 20 is located at the bottom of the supply cup assembly 60 , the second jaw assembly 20 is correspondingly located at the bottom of the sampler 50 , and the third jaw assembly 20 is correspondingly located at the bottom of the sealing assembly.

[0084] While the first gripper assembly 20 grasps the empty cup, the second gripper assembly 20 grasps the sampled cup 80, and the third gripper assembly 20 grasps the sealed sample cup 80. The conveyor assembly 30 simultaneously moves the first, second, and third gripper assemblies 20 to the right. The third gripper assembly 20 drops the sealed sample cup 80 into the collection chamber 70. The second gripper assembly 20 moves the sampled sample cup 80 to the bottom of the sealing assembly. The first gripper assembly 20 moves the empty cup to the bottom of the sampler 50 to await sampling. Subsequently, the first, second, and third gripper assemblies 20 open and are driven by the conveyor assembly 30 back to their initial positions for the next round of grasping.

[0085] By providing three gripping assemblies, a single round trip is all that is needed to complete a sampling operation, significantly improving the overall production cycle and sampling efficiency of the sampling device. Furthermore, if additional functional components are required on the frame 40, such as a filter assembly, a corresponding set of gripping assemblies can be added, and so on.

[0086] In another embodiment, the conveying assembly 30 includes a placement table 31, a slide 32, a fourth driving member 34, and a lifting platform 33. The slide 32 is movably arranged at the bottom of the placement table 31; the fourth driving member 34 is arranged on the slide 32; the lifting platform 33 is arranged on the fourth driving member 34, the clamping claw assembly 20 is arranged on the lifting platform 33, and the fourth driving member 34 is used to drive the lifting platform 33 to move up and down.

[0087] The top of the slide 32 has a flat surface for mounting the fourth drive member 34 and the lifting platform 33. The bottom has a track on which the platform moves via a linear module. The lifting platform 33 is used to provide a support platform for the clamping jaw assembly 20 and the third drive member 21.

[0088] The placement table 31 is positioned to correspond to the positions of the cup outlet 62 , the sampling port 42 , and the limiting hole, and is used to temporarily store the sampling cup 80 .

[0089] The fourth drive member 34 can be a pneumatic cylinder. After the gripper assembly 20 grabs the sampling cup 80, it drives the lifting platform 33 upward to lift the sampling cup 80 from the placement platform 31 for rightward transfer, preventing friction between the sampling cup 80 and the placement platform 31 during transfer. After transfer, the fourth drive member 34 drives the lifting platform 33 downward, temporarily placing the sampling cup 80 on the placement platform 31. The gripper assembly 20 releases the sampling cup 80 and returns to grab the next sampling cup 80.

[0090] In another embodiment, the cup supply assembly 60 further includes a fifth driving member 63 , which is disposed on one side of the storage box 61 , and is configured to drive the storage box 61 to move so that the position of the cup outlet 62 corresponds to the through hole 41 .

[0091] There is a mounting base 64 at the bottom of the storage box 61. The fifth driving member 63 can be a cylinder. The fifth driving member 63 can be extended and retracted to fine-tune the position of the storage box 61 so that the cup outlet 62 and the through hole 41 on the frame 40 correspond to each other, avoiding unsmooth cup discharge.

[0092] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
