Abstract
Description
Technical Field
[0001] This invention relates to the field of scientific and educational experimental instruments, and in particular to a sampling robot for scientific and educational laboratories. Background Technology
[0002] In science education experiments, it is often necessary to collect samples of different properties, such as plant tissues, cell clumps, culture medium suspensions, or mixtures, for subsequent microscopic observation, component analysis, or biochemical testing. Currently, laboratories commonly use simple tools such as handheld tweezers, droppers, and scissors for sampling, which presents the following common problems:
[0003] Handheld tools rely entirely on the experience of the experimenter; shaking or uneven force can easily cause samples to splash, drip, or break, especially unfriendly to small, viscous, or easily oxidized samples. The traditional multi-step process of "clamping-transferring-receiving" exposes samples to air for extended periods, causing moisture evaporation, degradation of active ingredients, or cross-contamination with other instruments, affecting experimental accuracy. Droppers or tweezers cannot precisely control the volume of samples taken or clamped, resulting in poor experimental repeatability; students need to perform repeated operations to obtain sufficient and representative samples. Existing sampling tools are mostly single-channel operations; if parallel comparison or sample backup is required, multiple samplings must be performed, which is time-consuming, labor-intensive, and prone to human error. Traditional sampling instruments have fixed structures and cannot be quickly replaced or upgraded with functional modules when facing different experimental objects (such as materials with large differences in hardness, such as peels, gels, and culture media), resulting in poor adaptability. Therefore, a sampling robot for science and education laboratories is proposed. Summary of the Invention
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a sampling robot for scientific and educational laboratories.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A sampling robot for a science and education laboratory includes a collection unit, a connecting crossbar, and a handheld unit. The handheld unit comprises a mounting component and a positioning component mounted on the lower end face of the mounting component. A transverse through-hole is mounted on the upper end face of the mounting component. One end of the transverse through-hole is connected in series with a protective cylinder via a vertical positioning component. A handheld strip is mounted on the other end face of the mounting component. A finger pressing plate is provided in the middle of the handheld strip. The collection unit and the connecting crossbar are installed inside the protective cylinder.
[0007] The operator uses the outer hand to hold the long strip and the finger-pressing plate as a handle for easy operation. The core sampling function of the device is achieved by the components inside the protective cylinder, which can reach into the target object for sampling. The installation components, positioning components, horizontal insertion plugs, and vertical positioning components improve the overall stability of the device, while the positioning components and horizontal insertion plugs act as connectors, firmly fixing the various parts of the device together.
[0008] Preferably, the collection unit includes an installation mechanism and a squeezing cylinder horizontally installed in the inner cavity of the installation mechanism. The two ends of the squeezing cylinder are connected to the two end faces of the inner cavity wall of the installation mechanism. An outer mounting ring is provided around the outer ring of the squeezing cylinder. The outer end face of the outer mounting ring is attached to the inner cavity wall of the pushing mechanism. A collection box is inserted into the other end of the pushing mechanism.
[0009] Preferably, the mounting mechanism includes a mounting shell and a connecting mechanism installed in the middle of the inner cavity of the mounting shell. A surrounding band is provided around both end walls of the mounting shell, and a hollow cavity is opened on the side end face of the surrounding band. A receiving head is provided at the intersection of the two sets of surrounding bands. The interval between the two sets of receiving heads allows for the collection of the fiber and cell mixture after plant tissue homogenization, improving the comprehensiveness and representativeness of the collected material. This facilitates more comprehensive and complete analysis and testing of the sample, resulting in a collection with more information and components, providing richer data for subsequent analysis and testing. It also helps to gain a deeper understanding of the basic condition of the fiber and cell mixture after plant tissue homogenization, allowing staff to observe the composition and structure of the sample more meticulously, providing more detailed information for subsequent testing and analysis.
[0010] Preferably, the two sets of opposite receiving heads are in contact with each other. Both the receiving heads and the sampling clamping rings are made of a synthetic rubber material. The operator holds the outer ring of the hand-held collar with both hands, which allows the operator to transport the entire device in parallel. When the operator lifts the two hand-held collars with both hands, the intersection of the two sets of sampling clamping rings and the two sets of receiving heads is placed vertically downward, which makes it convenient for the operator to collect cell clumps and suspended matter in the culture medium.
[0011] Preferably, the gap between the two sets of sampling clamping rings is freely and vertically downward in contact with the cell clumps and the suspended matter in the culture medium. The gap between the two sets of sampling clamping rings will clamp the cell clumps and the suspended matter in the culture medium in the area to be collected. The filamentous suspended matter clamped at the ends of the two sets of sampling clamping rings is quickly moved out of the collection area by the operator. The operator places the entire device in a balanced position with the outer end faces of the two sets of handheld collars as the bottom. The gap between the two sets of sampling clamping rings in the collection state is facing directly upward. The two sets of handheld collars bend outward under the pressure of the overall device's gravity, so that the outer end face of the mounting shell fits against the worktable. At this point, the filamentous suspended matter, held by two sets of sampling clamping rings, will fall freely to the gap between the two sets of receiving heads. At this time, the staff can push the pushing mechanism and the outer end face of the collection box from both sides inward. The pushing mechanism and the collection box are adjusted with the mounting mechanism as the fulcrum under the pushing force, thereby shortening the gap between the two sets of receiving heads. The filamentous suspended matter falling freely will be caught by the two sets of receiving heads. With the protruding outer contour structure of the receiving heads, the staff can more carefully observe and examine the collected cell clumps and the suspended matter in the culture medium, which helps to detect abnormalities in a timely manner.
[0012] Preferably, the mounting housing includes a housing shell and through cavities formed on both sides of the outer end face edge of the housing shell. Edge connection holes are formed at the bottom of both ends of the housing shell, and one end of a circumferential strip is inserted into the inner cavity of the edge connection hole.
[0013] Preferably, the connecting mechanism includes a connecting disc and a ring array of surrounding circular shafts arranged on the surface of the connecting disc. A contact groove is formed at the middle position of the side end face of the connecting disc. During the rotational adjustment of the entire pushing mechanism, one end of the pushing rod can gradually move around the outer ring of the outer mounting ring. When the overall position of the pushing mechanism is rotated and adjusted to the point where the two sets of pushing rods contact one side of the outer end face of the outer mounting ring, the outer mounting ring applies a pressing impact force to the extrusion cylinder inward. The end of the extrusion cylinder near the connecting mechanism extends outward to touch the contact groove and the surrounding circular shaft. The middle position of the rear end face of the connecting mechanism is attached to the middle position of the inner cavity wall of the outer shell. The connecting disc can rotate and swing around its center position within the inner cavity of the outer shell. One end of the extrusion cylinder expands intermittently and orderly. After contact, the extrusion cylinder contacts the outer end wall of the circular shaft and the contact groove. When one end of the extrusion cylinder expands and contacts the connecting mechanism in an orderly rotating and swinging state, the outer end wall of the circular shaft will intermittently squeeze the outer end face of the extrusion cylinder inward. Under the mechanical transmission of the components, when the filamentous suspension received by the receiving head vibrates and shakes, the mixed liquid sample in the inspection state falls to the outer end face of the mounting shell. Because the outer end face of the mounting shell is an arc structure, the mixed liquid sample will slide downward along the outer end face of the mounting shell at an angle. During the sliding process, the filamentous suspension will be received by two sets of side end faces of the circular belt, which will orderly and conveniently separate the water and solids in the filamentous suspension, making it convenient for staff to observe cell clumps and suspensions in the culture medium.
[0014] Preferably, the pushing mechanism includes a pushing rod and a pushing frame installed at one end of the pushing rod, with mounting plugs arranged on the inner end face of the pushing frame, and one end of the pushing rod inserted into the inner cavity of the through cavity;
[0015] Preferably, the collection box includes a box body and collection slots arranged on the upper and lower end faces of the box body. A through hole is provided at the edge of the upper end face of the box body, and mounting plugs arranged vertically are inserted into the inner cavity of the collection slots, so that the pushing mechanism and the collection box become a whole.
[0016] Preferably, the collection unit further includes a sampling clamping ring that passes through the inner cavity of the through hole. The other ends of the two sets of sampling clamping rings are connected in series by a hand-held collar. One end of the box body is inserted into the inner cavity of the hollow cavity. The inner wall of the push rod is attached to both sides of the outer end wall of the surrounding belt, so that the outer mounting ring, the push mechanism and the collection box become a whole. After the staff completes a series of checks and analyses, the box body is removed from the inner cavity of the push frame, the solid part of the mixture is placed into the inner cavity of the collection tank, and the two ends of the collection tank are filled with the set mounting plugs to keep the collected filamentous suspension in a relatively sealed and isolated state, so as to avoid the outside air from corroding the filamentous suspension. The above steps are repeated to continue to collect other cell clumps and suspensions in the culture medium.
[0017] Preferably, the acquisition unit further includes a direct acquisition mechanism installed at the middle position of the side end face of the mounting housing. The direct acquisition mechanism includes a sleeve cover and a push motor installed in the inner cavity of the sleeve cover. A sampling element is installed at the top end of the push motor, and the outer end wall of the sampling element is attached to the inner cavity wall of the sleeve cover.
[0018] Preferably, the tip of the sampling element can directly adhere to the sampled object, eliminating the three steps of "transfer chamber - dripping - receiving" and avoiding sample volatilization, oxidation, and cross-contamination. The extension length is controlled by a built-in micro linear motor in the drive motor, which can automatically adjust the extension length for fruit peels, gels, or culture media of different thicknesses / hardnesses, reducing human judgment errors. After sampling, the sampling element immediately retracts into the sleeve cover, and the silicone sealing piston instantly seals the tube opening, forming an integrated action of "single-point sampling and sample sealing". Traditional embodiments require an additional collection box to complete the sealing. The through channel, telescopic mechanism, and dynamic components are all integrated into the newly added module of the direct collection mechanism, which has no movement interference with the original extrusion cylinder and receiving head. It can be directly attached to existing equipment to achieve a "plug-and-play" upgrade.
[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0020] 1. The two sets of sampling clamping rings freely and vertically contact the cell clumps and culture medium suspension at the interval between them. The interval between the two sets of sampling clamping rings will clamp the cell clumps and culture medium suspension in the area to be collected. The cell clumps and culture medium suspension held by the two sets of sampling clamping rings will fall freely to the interval between the two sets of receiving heads. At this time, the staff can push the pushing mechanism and the outer end face of the collection box from both sides inward. The pushing mechanism and the collection box are adjusted with the mounting mechanism as the fulcrum under the pushing force, thereby shortening the distance between the two sets of receiving heads. The cell clumps and culture medium suspension falling freely will be caught by the two sets of receiving heads. The staff can observe and inspect the collected cell clumps and culture medium suspension more carefully by using the protruding outer contour structure of the receiving heads, which helps to detect abnormalities in a timely manner.
[0021] 2. During the rotational adjustment of the entire pushing mechanism, one end of the pushing rod can gradually move around the outer ring of the outer mounting ring. When the overall position of the pushing mechanism is rotated and adjusted until the two sets of pushing rods contact one side of the outer end face of the outer mounting ring, the outer mounting ring applies a pressing impact force to the extrusion cylinder. The end of the extrusion cylinder near the connecting mechanism extends outward to touch the contact groove and the surrounding circular shaft. The middle position of the rear end face of the connecting mechanism is attached to the middle position of the inner cavity wall of the outer shell. The connecting disc can rotate and swing around its center position in the inner cavity of the outer shell. One end of the extrusion cylinder intermittently and orderly expands and contacts the outer end wall of the surrounding circular shaft and the contact groove. When the end expands and contacts the connecting mechanism in an orderly rotating and oscillating state, the outer end wall surrounding the circular shaft will intermittently squeeze the outer end face of the extrusion cylinder inward. Under the mechanical transmission of the components, when the mixed liquid collected by the receiving head vibrates and shakes, the mixed liquid collected in the inspection state falls to the outer end face of the mounting shell. Because the outer end face of the mounting shell is an arc structure, the mixed liquid collected will slide downward along the outer end face of the mounting shell at an angle. During the sliding process, the mixed liquid collected will be received by two sets of side end faces of the surrounding belt, which will orderly and conveniently separate the water and solids in the mixed liquid, making it convenient for staff to observe cell clumps and suspended matter in the culture medium.
[0022] 3. The two sets of receiving probes can catch suspended matter that falls off from the mixed liquid sample, improving the comprehensiveness and representativeness of the sample. This helps to analyze and test the sample more comprehensively and completely. The obtained sample contains more information and composition, which can provide richer data for subsequent analysis and testing. It helps to understand the health status and digestion of animals more deeply. Staff can observe the composition and structure of the sample more carefully, providing more detailed information for subsequent testing and analysis.
[0023] 4. After the staff completes a series of checks and analyses, remove the box from the inner cavity of the pusher, place the solid part of the mixture into the inner cavity of the collection tank, and fill the two ends of the collection tank with the set installation plugs to keep the collected mixture in a relatively sealed and isolated state, so as to prevent the outside air from corroding the collected mixture. Repeat the above steps to continue collecting other cell clumps and suspended matter in the culture medium.
[0024] 5. The tip of the sampling piece can directly contact the sampled object, eliminating the three steps of "transfer chamber - dripping - receiving", avoiding sample volatilization, oxidation and cross-contamination; the extension length is controlled by a built-in micro linear motor of the drive motor, which can automatically adjust the extension length for fruit peels, gels or culture media of different thicknesses / hardness, reducing human judgment errors; after sampling, the sampling piece immediately retracts into the sleeve cover, and the silicone sealing piston instantly seals the tube opening, forming an integrated action of "single-point sampling and sample sealing", which requires an additional collection box to complete the sealing in traditional embodiments; the through channel, telescopic mechanism and dynamic components are all integrated into the newly added module of direct collection mechanism, which has no movement interference with the original extrusion cylinder and receiving head, and can be directly attached to the existing equipment to achieve "plug-and-play" upgrade.

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0038] Reference Figures 1-11 Example 1: A sampling robot for a science and education laboratory includes a collection unit 1, a connecting crossbar 2, and a handheld unit 3. The handheld unit 3 includes a mounting component 31 and a positioning component 32 mounted on the lower end face of the mounting component 31. A transverse insert 33 is mounted on the upper end face of the mounting component 31. One end of the transverse insert 33 is connected in series with a protective cylinder 35 via a vertical positioning component 34. A handheld strip 36 is mounted on the other end face of the mounting component 31. A finger pressing plate 37 is provided in the middle of the handheld strip 36. The collection unit 1 and the connecting crossbar 2 are installed inside the protective cylinder 35.
[0039] The operator uses the outer hand to hold the long strip 36 and the finger pressing plate 37 as a handle for easy operation. The core sampling function of the device is achieved by 1 and 2 in the inner cavity of the protective cylinder 35, which can extend into the target object for sampling. The installation of mounting parts 31, positioning parts 32, horizontal insertion parts 33 and vertical positioning parts 34 improves the overall stability of the device, while positioning parts 32 and horizontal insertion parts 33 act as connectors, firmly fixing the various parts of the device together.
[0040] The collection unit 1 includes an installation mechanism 11 and a squeezing cylinder 12 that is horizontally installed in the inner cavity of the installation mechanism 11. The two ends of the squeezing cylinder 12 are connected to the two end faces of the inner cavity wall of the installation mechanism 11. An outer mounting ring 13 is provided around the outer ring of the squeezing cylinder 12. The outer end face of the outer mounting ring 13 is attached to the inner cavity wall of the pushing mechanism 14. A collection box 15 is inserted through the other end of the pushing mechanism 14.
[0041] The mounting mechanism 11 includes a mounting housing 111 and a connecting mechanism 112 installed in the middle of the inner cavity of the mounting housing 111. The mounting housing 111 has a surrounding band 113 around its two end walls. The side end face of the surrounding band 113 has a hollow cavity 114. The receiving head 115 is set at the intersection of the two sets of surrounding bands 113. The interval between the two sets of receiving heads 115 can receive the fiber and cell mixture after plant tissue homogenization, which improves the comprehensiveness and representativeness of the collected material. It helps to analyze and detect the sample more comprehensively and completely. The collected material has more information and composition, which can provide richer data for subsequent analysis and detection. It helps to understand the basic condition of the fiber and cell mixture after plant tissue homogenization more deeply. The staff can observe the composition and structure of the sample more carefully, which provides more detailed information for subsequent detection and analysis.
[0042] In Example 2, the two sets of opposing receiving heads 115 are in contact with each other. Both the receiving heads 115 and the sampling clamping rings 16 are made of synthetic rubber. When the staff removes the 35, the staff can hold the outer ring of the hand-held collar 17 with their other hand and move the whole device in parallel with both hands. When the staff lifts the two hand-held collars 17 with both hands, the intersection of the two sets of sampling clamping rings 16 and the two sets of receiving heads 115 is placed vertically downward, which makes it convenient for the staff to collect cell clumps and suspended matter in the culture medium.
[0043] The space between the two sets of sampling clamping rings 16 is freely and vertically downward in contact with the cell clumps and culture medium suspension. The space between the two sets of sampling clamping rings 16 will clamp the cell clumps and culture medium suspension in the area to be collected. The filamentous suspension held at the ends of the two sets of sampling clamping rings 16 is quickly moved out of the collection area by the operator. The operator places the entire device in a balanced position with the outer end faces of the two sets of handheld collars 17 as the base. The space between the two sets of sampling clamping rings 16 in the collection state is facing directly upward. The two sets of handheld collars 17 bend outward under the pressure of the overall device, so that the outer end face of the mounting shell 111 fits against the workbench surface. At this time, the two sets of sampling clamping rings 16 are in contact with the cell clumps and culture medium suspension in the area to be collected. The filamentous suspended matter held by the sample clamping ring 16 will fall freely to the gap between the two sets of receiving heads 115. At this time, the staff can push the outer end face of the pushing mechanism 14 and the collection box 15 from both sides. The pushing mechanism 14 and the collection box 15 are adjusted with the mounting mechanism 11 as the fulcrum under the pushing force, thereby shortening the gap between the two sets of receiving heads 115. The filamentous suspended matter falling freely will be received by the two sets of receiving heads 115. With the protruding outer contour structure of the receiving head 115, the staff can more carefully observe and inspect the collected cell clumps and the suspended matter in the culture medium, which helps to detect abnormalities in a timely manner.
[0044] Example 3: The mounting housing 111 includes a housing 1111 and a through cavity 1112 opened on both sides of the outer end face edge of the housing 1111. Edge connection holes 1113 are opened at the bottom of both ends of the housing 1111. One end of the circumferential band 113 is inserted into the inner cavity of the edge connection hole 1113.
[0045] The linkage mechanism 112 includes a linkage disk 1121 and a ring array of surrounding circular shafts 1122 arranged on the surface of the linkage disk 1121. A contact groove 1123 is formed at the middle position of the side end face of the linkage disk 1121. During the rotation adjustment of the entire pushing mechanism 14, one end of the pushing rod 141 can move gradually around the outer ring of the outer mounting ring 13. When the overall position of the pushing mechanism 14 is rotated and adjusted to the point where the two sets of pushing rods 141 contact one side of the outer end face of the outer mounting ring 13, the outer mounting ring 13 applies a pressing impact force to the extrusion cylinder 12 inward. The end of the extrusion cylinder 12 near the linkage mechanism 112 extends outward to touch the contact groove 1123 and the surrounding circular shaft 1122. The middle position of the rear end face of the linkage mechanism 112 is attached to the middle position of the inner cavity wall of the outer shell 1111. The linkage disk 1121 can rotate and swing around its center position within the inner cavity of the outer shell 1111. After one end of the extrusion cylinder 12 expands intermittently and orderly, it contacts the outer end wall of the circular shaft 1122 and the contact groove 1123. When one end of the extrusion cylinder 12 contacts the connecting mechanism 112 in an orderly rotating and swinging state after expansion, the outer end wall of the circular shaft 1122 will intermittently squeeze the outer end face of the extrusion cylinder 12 inward. Under the mechanical transmission of the components, when the filamentous suspension received by the receiving head 115 is vibrated and shaken, the mixed liquid collected in the inspection state falls to the outer end face of the mounting shell 111. Since the outer end face of the mounting shell 111 is an arc structure, the mixed liquid collected will slide downward along the outer end face of the mounting shell 111. During the sliding process, the filamentous suspension will be received by the side end faces of the two sets of surrounding belts 113, which will separate the water and solid in the filamentous suspension in an orderly and convenient manner, making it convenient for staff to observe cell clumps and suspensions in the culture medium.
[0046] Example 4: The pushing mechanism 14 includes a pushing rod 141 and a pushing frame 142 installed at one end of the pushing rod 141. The inner end face of the pushing frame 142 is provided with mounting plugs 143. One end of the pushing rod 141 is inserted into the inner cavity of the through cavity 1112.
[0047] The collection box 15 includes a box body 151 and collection grooves 152 arranged on the upper and lower end faces of the box body 151. A through hole 153 is provided at the edge of the upper end face of the box body 151. The mounting plugs 143 arranged vertically are inserted into the inner cavity of the collection grooves 152, so that the pushing mechanism 14 and the collection box 15 become a whole.
[0048] The collection unit 1 also includes a sampling clamping ring 16 that passes through the inner cavity of the through hole 153. The other ends of the two sets of sampling clamping rings 16 are connected in series by a hand-held collar 17. One end of the box body 151 is inserted into the inner cavity of the hollow cavity 114. The inner wall of the push rod 141 is attached to both sides of the outer end wall of the surrounding belt 113, so that the outer mounting ring 13, the push mechanism 14 and the collection box 15 become a whole. After the staff completes a series of inspections and analyses, the box body 151 is removed from the inner cavity of the push frame 142. The solid part of the mixture is placed into the inner cavity of the collection tank 152, and the two ends of the collection tank 152 are filled with the installation plugs 143 to keep the collected filamentous suspension in a relatively sealed and isolated state, so as to prevent the outside air from eroding the filamentous suspension. The above steps are repeated to continue collecting other cell clumps and suspensions in the culture medium.
[0049] Example 5 proposes a different embodiment, in which the acquisition unit 1 further includes a direct acquisition mechanism 18 installed at the middle position of the side end face of the mounting housing 111. The direct acquisition mechanism 18 includes a sleeve cover 181 and a push motor 182 installed in the inner cavity of the sleeve cover 181. A sampling element 183 is installed at the top end of the push motor 182, and the outer end wall of the sampling element 183 is attached to the inner cavity wall of the sleeve cover 181.
[0050] The tip of the sampling element 183 can directly adhere to the sampled object, eliminating the three steps of "transfer chamber - dripping - receiving" and avoiding sample volatilization, oxidation, and cross-contamination. The extension length is controlled by a built-in micro linear motor in the drive motor 182, which can automatically adjust the extension length for fruit peels, gels, or culture media of different thicknesses / hardnesses, reducing human judgment errors. After sampling, the sampling element 183 immediately retracts into the sleeve cover 181, and the silicone sealing piston instantly seals the tube opening, forming an integrated action of "single-point sampling and sample sealing". In traditional embodiments, an additional collection box 15 is required to complete the sealing. The through channel, telescopic mechanism, and dynamic components are all integrated into the newly added module of the direct collection mechanism 18, which has no movement interference with the original extrusion cylinder 12 and receiving head 115. It can be directly attached to existing equipment to achieve a "plug-and-play" upgrade.
[0051] In summary: the operator uses the outer hand to hold the long strip 36 and the finger pressing plate 37 as a handle for easy operation. The core sampling function of the device is achieved by 1 and 2 inside the protective cylinder 35, which can extend into the target object for sampling. The installation of mounting parts 31, positioning parts 32, horizontal insertion parts 33, and vertical positioning parts 34 improves the overall stability of the device, while positioning parts 32 and horizontal insertion parts 33 act as connectors, firmly fixing the various parts of the device together.
[0052] The two sets of receiving probes 115 spaced apart can receive the fiber and cell mixture after plant tissue homogenization, improving the comprehensiveness and representativeness of the collected samples. This facilitates more comprehensive and complete analysis and testing of the samples, and the collected samples contain more information and components, providing richer data for subsequent analysis and testing. It also helps to gain a deeper understanding of the basic condition of the fiber and cell mixture after plant tissue homogenization. Staff can observe the composition and structure of the samples more closely, providing more detailed information for subsequent testing and analysis.
[0053] The staff removes 35, and at this time the staff holds the outer ring of the handheld collar 17 with their other hand, and can move the whole device in parallel with both hands.
[0054] When the staff member lifts the two hand rings 17 with both hands clasped inward, the intersection of the two sets of sampling clamping rings 16 and the two sets of receiving bullets 115 is placed vertically downward, which makes it convenient for the staff member to collect cell clumps and suspended matter in the culture medium.
[0055] The space between the two sets of sampling clamping rings 16 is freely and vertically downward to contact the cell clumps and the suspended matter in the culture medium. The space between the two sets of sampling clamping rings 16 will clamp the cell clumps and the suspended matter in the culture medium in the area to be collected. The filamentous suspended matter clamped at the ends of the two sets of sampling clamping rings 16 is quickly moved out of the collection area by the staff. The staff places the whole device in a balanced position with the outer end face of the two sets of hand-held collars 17 as the bottom. The space between the two sets of sampling clamping rings 16 in the collection state is facing directly upward. The two sets of hand-held collars 17 bend outward under the pressure of the weight of the whole device, so that the outer end face of the mounting shell 111 fits against the workbench surface.
[0056] At this time, the filamentous suspended matter held by the two sets of sampling clamping rings 16 will fall freely to the gap between the two sets of receiving heads 115. At this time, the staff can push the outer end face of the pushing mechanism 14 and the collection box 15 inward from both sides. The pushing mechanism 14 and the collection box 15 are adjusted with the mounting mechanism 11 as the fulcrum under the pushing force, thereby shortening the gap between the two sets of receiving heads 115. The filamentous suspended matter falling freely will be received by the two sets of receiving heads 115. With the protruding outer contour structure of the receiving head 115, the staff can more carefully observe and inspect the collected cell clumps and the suspended matter in the culture medium, which helps to detect abnormalities in a timely manner.
[0057] During the rotational adjustment of the entire pushing mechanism 14, one end of the pushing rod 141 can gradually move around the outer ring of the outer mounting ring 13. When the overall position of the pushing mechanism 14 is rotated and adjusted to the point where the two sets of pushing rods 141 contact one side of the outer end face of the outer mounting ring 13, the outer mounting ring 13 applies a pressing impact force to the extrusion cylinder 12. The end of the extrusion cylinder 12 near the connecting mechanism 112 extends outward to touch the contact groove 1123 and the surrounding circular shaft 1122. The middle position of the rear end face of the connecting mechanism 112 is attached to the middle position of the inner cavity wall of the outer shell 1111. The connecting disc 1121 can rotate and swing around its center position in the inner cavity of the outer shell 1111. One end of the extrusion cylinder 12 expands intermittently and orderly, then contacts the surrounding circular shaft 1122 and the contact groove. When one end of the extrusion cylinder 12 contacts the connecting mechanism 112, which is in an orderly rotating and swinging state, after expansion, the outer end wall of the circular shaft 1122 will intermittently extrude the outer end face of the extrusion cylinder 12. Under the mechanical transmission of the components, when the filamentous suspension received by the receiving head 115 is vibrating and shaking, the mixed liquid collected in the inspection state falls to the outer end face of the mounting shell 111. Since the outer end face of the mounting shell 111 is an arc-shaped structure, the mixed liquid collected will slide downward along the outer end face of the mounting shell 111. During the sliding process, the filamentous suspension will be received by the side end faces of the two sets of surrounding belts 113, which will orderly and conveniently separate the water and solids in the filamentous suspension, making it convenient for staff to observe cell clumps and suspensions in the culture medium.
[0058] After the staff completes a series of checks and analyses, the box 151 is removed from the inner cavity of the pusher 142, the solid part of the mixture is placed into the inner cavity of the collection tank 152, and the two ends of the collection tank 152 are filled with the installation plugs 143 to keep the collected filamentous suspension in a relatively sealed and isolated state, so as to prevent the outside air from corroding the filamentous suspension. The above steps are repeated to continue collecting other cell clumps and suspensions in the culture medium.
[0059] The tip of the sampling element 183 can directly adhere to the sampled object, eliminating the three steps of "transfer chamber - dripping - receiving" and avoiding sample volatilization, oxidation, and cross-contamination. The extension length is controlled by a built-in micro linear motor in the drive motor 182, which can automatically adjust the extension length for fruit peels, gels, or culture media of different thicknesses / hardnesses, reducing human judgment errors. After sampling, the sampling element 183 immediately retracts into the sleeve cover 181, and the silicone sealing piston instantly seals the tube opening, forming an integrated action of "single-point sampling and sample sealing". In traditional embodiments, an additional collection box 15 is required to complete the sealing. The through channel, telescopic mechanism, and dynamic components are all integrated into the newly added module of the direct collection mechanism 18, which has no movement interference with the original extrusion cylinder 12 and receiving head 115. It can be directly attached to existing equipment to achieve a "plug-and-play" upgrade.
