[0025] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0026] The following combination Figure 1 The utility model describes the automatic opening and closing mechanism of a test paper can.

[0027] The utility model provides an automatic opening and closing mechanism for a test paper can. Figure 1 and Figure 4As shown, the apparatus comprises a support base 111, a test strip storage tank 40, a lid opening jaw 93, and a first linear module 91. The first linear module 91 is located on one side of the support base 111, and the lid opening jaw 93 is slidably mounted on the first linear module 91 to move closer to or further away from the test strip storage tank 40. The test strip storage tank 40 comprises a tank body 41, a lid 42, and a flexible block disposed within the tank body 41. The lid 42 covers the opening of the tank body 41. The flexible block is provided with multiple slots 43, each of which contains a test strip. The lid opening jaw 93 can grip the lid 42 to open the test strip storage tank 40 or close the lid 42 over the opening of the tank body 41.

[0028] The first linear module 91 is a mechanical structure capable of providing linear motion. Under the action of the first linear module 91, the lid opening clamp 93 approaches the test paper storage tank 40, clamps the cover 42, and as the first linear module 91 moves in the opposite direction, the cover 42 is removed from the tank body 41. After the test paper is taken out of the tank body 41, the first linear module 91 drives the lid opening clamp 93 to approach the test paper storage tank 40 again, and puts the cover 42 back on the tank body 41 to prevent dust and other impurities from entering and contaminating the test paper. It should be noted that the first linear module 91 can open or close the tank body 41 every time a test paper is taken out, or it can be opened and kept open after the rheological station automated detection device receives the sample, and the cover 42 is then put back on the tank body 41 when the rheological station automated detection device is closed that day. The specific setting is determined according to needs.

[0029] The first linear module 91 can be fixed to the support base 111 or be separated from the support base 111 ; as long as the first linear module 91 can drive the cover opening jaws 93 to move closer to or away from the test paper storage jar 40 on the support base 111 , it will be sufficient.

[0030] Optionally, the flexible block is a sponge or silicone member. The flexible block is provided with multiple through holes or blind holes serving as slots 43. A test strip is inserted into each slot 43, utilizing the flexibility of the flexible block to prevent damage to the test strip. Specifically, the depth of slots 43 is greater than half the length of the test strip, ensuring that the test strip remains upright when inserted.

[0031] The cover 42 is placed over the open end of the tank 41 to prevent external dust from contaminating the test paper. When the test paper is not in use, the cover 42 is placed on the tank 41. When the test paper is needed, the cover 42 is opened. Specifically, the first linear module 91 drives the cover-opening jaws 93 to open the cover 42 in advance and place the cover 42 on the side of the tank 41, or to hold the cover 42 until the test paper in the tank 41 is removed, at which time the cover 42 is replaced on the tank 41.

[0032] In an alternative embodiment, the can body 41 is cylindrical, and a connector protrudes from the cover 42. The cover-opening jaws 93 directly grip the connector when gripping the cover 42, thereby removing the cover 42 from the can body 41 or replacing the cover 42 in the can body 41. In another alternative embodiment, the cover 42 has a certain thickness, and when it is placed on the can body 41, its outer edge protrudes beyond the outer wall of the can body 41. The cover-opening jaws 93 directly grip both sides of the cover 42, thereby removing the cover 42 from the can body 41 or replacing the cover 42 in the can body 41.

[0033] The automatic opening and closing mechanism of the test paper jar provided in the embodiment of the present invention has a cover opening claw 93 that can open the test paper storage jar 40 before the robot 20 picks up the test paper, so that the robot 20 can directly take the test paper after moving over without the need to open and close the cover, thereby improving the detection efficiency of the rheology station automatic detection device.

[0034] like Figure 1 As shown, the automatic opening and closing mechanism for the test strip jar further includes a second linear module 92. Multiple test strip storage jars 40 are provided, arranged side by side along the length of the second linear module 92. The opening jaws 93 are mounted to the first linear module 91 via the second linear module 92, with the sliding directions of the first and second linear modules 91 and 92 being perpendicular.

[0035] The second linear module 92 and the first linear module 91 work together to enable the lid-opening jaw 93 to move freely within the horizontal plane. The first linear module 91 drives the lid-opening jaw 93 toward or away from the can 41, while the second linear module 92 drives the lid-opening jaw 93 between different cans 41. When the test strips in one can 41 are completely removed, the second linear module 92 drives the lid-opening jaw 93 to move to the next can 41. The first linear module 91 then drives the lid-opening jaw 93 toward or away from the can 41, opening and closing the corresponding test strip storage can 40.

[0036] In a specific embodiment, the support base 111 has a first groove and a second groove. The can body 41 is clamped in the first groove, and the second groove is used to place the cover body 42.

[0037] The first groove and the second groove have different groove depths. In one embodiment, the bottom of the second groove is provided with a depression. When the cover body 42 is placed in the second groove, the bottom surface of the cover body 42 does not contact the bottom of the second groove, thereby avoiding contamination of the cover body 42. It should be noted that if the robot 20 directly clamps the outer side of the cover body 42, then when the cover body 42 is placed in the second groove, most of the position protrudes outside the second groove, making it convenient for the cover opening jaws 93 to clamp the cover body 42. If the cover opening jaws 93 clamp the protruding connector on the cover body 42, most of the cover body 42 can be accommodated in the second groove. In the case where there are multiple test paper storage cans 40, multiple support bases 111 are arranged in parallel, and each support base 111 is provided with a first groove; or, multiple first grooves are arranged in parallel on a single support base 111.

[0038] During use, the lid-opening jaw 93 moves the lid body 42 from the tank body 41 to the second groove under the action of the second linear module, and then the lid-opening jaw 93 is released, and the lid body 42 falls into the second groove. In one embodiment, the lid-opening jaw 93 is rotatably mounted on the slider of the second linear module, and the clamping end of the lid-opening jaw 93 is rotated up and down by rotation to achieve a small upward movement after clamping the lid body 42 to separate the lid body 42 from the tank body 41, and then after moving to the target position, it is slightly moved downward to cover the lid body 42 back to the tank body 41 or put it into the second groove. In another embodiment, the lid-opening jaw 93 is fixedly mounted on the slider of the second linear module. The height of the lid-opening jaw 93 is adapted to the height of the lid body 42, and the lid body 42 is clamped and released by opening and closing the lid-opening jaw 93.

[0039] The test paper area 11 is provided with a plurality of test paper storage tanks 40 to increase the amount of test paper stored in the test paper area 11. Figure 4 As shown, the test strip area 11 is equipped with three test strip storage tanks 40, each arranged in parallel. Correspondingly, there are three first grooves, each containing a test strip storage tank 40. The robot 20 picks a test strip from one of the test strip storage tanks 40 and, after the first tank 40 has been cleared, picks up a test strip from the next tank 40.

[0040] To reduce collision, a flexible pad is provided at the bottom of the second groove. For example, a flexible pad such as a rubber pad or a sponge layer is provided at the groove wall of the second groove.

[0041] Specifically, the cover opening jaw 93 includes a mounting base 94 , a first jaw 95 and a second jaw 96 . The mounting base 94 is mounted on the slider of the first linear module 91 , and at least one of the first jaw 95 and the second jaw 96 is movably mounted on the mounting base 94 .

[0042] The mounting base 94 can be rotatably mounted on the slider of the first linear module 91 or fixedly mounted on the slider of the first linear module 91. In the case where the mounting base 94 is rotatably mounted on the slider of the first linear module 91, after the lid opening jaw 93 moves to the position of the lid body 42, the mounting base 94 rotates to drive the first jaw 95 and the second jaw 96 to move slightly downward, so that the first jaw 95 and the second jaw 96 are respectively arranged on opposite sides of the lid body 42. Then, the first jaw 95 and the second jaw 96 move together to clamp the lid body 42 and move away from the can body 41 as the mounting base 94 rotates in the opposite direction, separating the can body 41 and the lid body 42. Then, the first linear module 91 drives the lid body 42 away from the can body 41. When closing the can 41, the first linear module 91 moves the lid 42 above the can 41. The mounting base 94 then rotates, causing the lid 42, held by the first and second clamping jaws 95 and 96, to move downward, reducing the distance between the lid 42 and the can 41. The first and second clamping jaws 95 and 96 then release, allowing the lid 42 to drop into the opening of the can 41. With the mounting base 94 secured to the slider of the first linear module 91, the heights of the first and second clamping jaws 95 and 96 match those of the lid 42. The outer edge of the lid 42 protrudes beyond the can 41. When gripping the lid 42, the first and second clamping jaws 95 and 96 either remain free of contact with the can 41 or engage with a raised portion of the lid 42. The reciprocating motion of the first linear module 91 allows the can 41 to open and close.

[0043] The utility model also provides a rheological station automatic detection device including the above test paper tank automatic opening and closing mechanism, Figure 2-Figure 4 The utility model describes an automatic detection device for a rheological station.

[0044] The utility model provides an automatic detection device for a rheological station, such as Figures 2 to 4 As shown, it includes an operating table 10, a robot 20, a rheometer 30, a visual inspection unit 50 and the automatic opening and closing mechanism of the test paper can as described above. Figure 4 As shown, the operating table 10 has a test paper area 11, a sample area 12 and a test area 13. The support base 111 and the first linear module 91 are placed in the test paper area 11. The sample area 12 is used to place the sample bottles to be tested. The robot 20 is fixed to the operating table 10. The robot 20 can transfer the sample bottles to be tested from the sample area 12 to the test area 13, and can pick up the test paper from the test paper storage tank 40 after the opening jaws 93 open the test paper storage tank 40 to detect the sample to be tested located in the test area 13. The shooting field of the visual inspection unit 50 is toward the test area 13, and is used to shoot the test paper after the sample is tested. Figure 2 and Figure 4 As shown, the rheometer 30 is fixed to the operating table 10, and the robot 20 can transfer the sample bottle to be tested from the sample area 12 to the rheometer 30 for viscosity testing.

[0045] The operating table 10 is a table or a cabinet. Figure 2 As shown, a universal wheel 16 is installed under the operating table 10. When the position of the operating table 10 needs to be adjusted, it is moved with the help of the universal wheel 16. After moving into place, the universal wheel 16 is locked and fixed at the target position. The robot 20, the rheometer 30, the automatic opening and closing mechanism of the test paper tank and the visual inspection unit 50 are all fixed on the operating table 10. Among them, the operating table 10 has a sample area 12 for placing the sample bottle to be tested and a test area 13 for performing test paper testing. The robot 20 is used to move between the sample area 12, the test area 13, the rheometer 30 and the test paper storage tank 40. The sample area 12 is provided with a sample holder 121, and the sample holder 121 is provided with a plurality of slots, each of which can hold a sample bottle to be tested, and the sample bottle to be tested is positioned with the help of the slot. The test area 13 is provided with a limit seat, and the limit seat is provided with a limit groove. The sample bottle to be tested is taken out of the slot by the robot 20 and placed in the limit groove for positioning.

[0046] Specifically, when the sample needs to be tested with the help of test paper for related items, the robot 20 transfers the sample bottle to be tested from the sample area 12 to the test area 13 and places the sample bottle to be tested in the test area 13. Then the robot 20 takes the test paper from the test paper storage tank 40 opened by the test paper tank automatic opening and closing mechanism, inserts the test paper into the sample liquid in the sample bottle to be tested, and after the test paper test is completed, the robot 20 removes the test paper from the sample bottle to be tested. The visual inspection unit 50 photographs the test paper after testing the sample to be tested, and determines the test result of the sample to be tested through image analysis. Optionally, the robot 20 starts timing after inserting the test paper into the sample to be tested, and simulates human hand movements after a preset period of time to knock off excess sample liquid at the mouth of the sample bottle to be tested.

[0047] When the viscosity of the sample needs to be tested with the help of the rheometer 30, the robot 20 transfers the sample bottle to be tested from the sample area 12 to the test area 13 and then to the rheometer 30, and places it at the operating position of the rheometer 30. Then, the rheometer 30 is started, and the sample bottle to be tested is moved up to contact the rotor of the rheometer 30. The rotor stirs the sample bottle to be tested to obtain viscosity information of the sample to be tested.

[0048] The rheology station automated detection device provided by the embodiment of the present invention replaces manual labor by a robot 20 fixedly mounted on an operating table 10, and reduces the operating steps of the robot 20 with the help of an automatic opening and closing mechanism of a test paper can, thereby improving the degree of automation, further improving the detection efficiency and consistency of the detection results, and reducing the dependence of the detection items on manual labor, thereby reducing labor costs.

[0049] The rheological station automated detection device also includes a test paper auxiliary bracket 61, a first clamping plate 62 and a second clamping plate 63. The test paper auxiliary bracket 61 is fixed to the operating table 10, and at least one of the first clamping plate 62 and the second clamping plate 63 can be slidably installed on the test paper auxiliary bracket 61 so that the first clamping plate 62 and the second clamping plate 63 can be close to or away from each other to clamp the test paper after the sample is tested.

[0050] In one embodiment, the first clamping plate 62 is fixed on the test paper auxiliary bracket 61, and the second clamping plate 63 can be slidably mounted on the test paper auxiliary bracket 61. After the robot 20 takes the test paper out of the sample bottle to be tested, the second clamping plate 63 moves toward the first clamping plate 62 to clamp the test paper between the two. The visual inspection unit 50 takes an image of the test paper after dipping the sample from the side. In another embodiment, the first clamping plate 62 and the second clamping plate 63 can both be slidably mounted on the test paper auxiliary bracket 61. The first clamping plate 62 and the second clamping plate 63 are close to each other to clamp the area of the test paper that is not dipped in the sample. This allows the robot 20 to perform other operations during the waiting time, thereby improving detection efficiency. Of course, the robot 20 can also directly hold the test paper and wait for the visual inspection unit 50 to take pictures for detection.

[0051] In a specific embodiment, if Figure 3 As shown, the robot 20 includes a base 21, a first robotic arm 22, a second robotic arm 23, a third robotic arm 24, and a gripper 25. The base 21 is fixed to the operating table 10. The first robotic arm 22 is rotatably mounted on the base 21 about a first direction. The first end of the second robotic arm 23 is rotatably mounted on one end of the first robotic arm 22 about a second direction. The third robotic arm 24 is rotatably mounted on the second end of the second robotic arm 23 about the second direction. The first and third robotic arms 22, 24 are arranged in parallel. The gripper 25 is rotatably mounted on the third robotic arm 24. The first direction is perpendicular to the second direction.

[0052] The base 21 is fixed to the operating table 10 by bolts, and the first mechanical arm 22 is rotatably connected to the base 21. Figure 3 As shown, the base 21 is provided with a mounting slot, and a connecting protrusion is provided in the middle of the first robotic arm 22. The connecting protrusion is accommodated in the mounting slot. A shaft extends through the connecting protrusion and connects to the opposite side wall of the mounting slot, thereby rotationally connecting the first robotic arm 22 and the base 21. A first rotary drive member is mounted on the base 21 and is in transmission connection with the first robotic arm 22 to drive the first robotic arm 22 to rotate about the shaft. The first rotary drive member is a pneumatic drive mechanism or a rotary motor. Optionally, the first direction is vertical, and the first robotic arm 22 can rotate left and right around the base 21.

[0053] The first end of the second robotic arm 23 is rotationally connected to the end of the first robotic arm 22, and the second end of the second robotic arm 23 is rotationally connected to the end of the third robotic arm 24. For example, the end of the first robotic arm 22 is provided with two lugs, and the second robotic arm 23 is accommodated between the two lugs. A rotating shaft passes through the two lugs and the second robotic arm 23, rotationally connecting the first robotic arm 22 and the second robotic arm 23 together. A second rotary drive member is mounted within the first robotic arm 22 and connected to the second robotic arm 23 for driving the second robotic arm 23 to rotate about the rotating shaft. Similarly, the second rotary drive member is a pneumatic drive mechanism or a rotary motor. The connection between the third robotic arm 24 and the second robotic arm 23 is similar to the connection between the first robotic arm 22 and the second robotic arm 23, and will not be further described. The second direction is a horizontal direction. The height and fore-and-aft position of the gripper 25 can be adjusted by rotating the second robotic arm 23 relative to the first robotic arm 22 and the third robotic arm 24 relative to the second robotic arm 23.

[0054] like Figure 3 As shown, the third mechanical arm 24 is T-shaped, one end of which is rotatably connected to the second mechanical arm 23, and the middle support rod is connected to the clamping claw 25. With the help of the rotation connection between the clamping claw 25 and the third mechanical arm 24, the clamping claw 25 can be made to pitch or move left and right.

[0055] The utility model provides an automated detection device for a rheological station, in which the first robotic arm 22 rotates relative to the base 21, the second robotic arm 23 rotates relative to the first robotic arm 22, the third robotic arm 24 can rotate relative to the second robotic arm 23, and the clamp 25 rotates relative to the third robotic arm 24. Thus, the clamp 25 can move freely in three-dimensional space, and all detection actions can be completed on the operating table 10 with the help of a robot 20, simplifying the device structure.

[0056] The clamping jaw 25 includes a clamping jaw seat, a main clamping jaw and an auxiliary clamping jaw. The clamping jaw seat can be rotatably mounted on the third mechanical arm 24, and the main clamping jaw and the auxiliary clamping jaw can be movably mounted on the clamping jaw seat to move closer to or farther away from each other.

[0057] The gripper seat is rotatably connected to the third robotic arm 24. The third robotic arm 24 is T-shaped, with one lateral end rotatably connected to the top end of the second robotic arm 23, and the gripper seat is installed on the vertical end. Specifically, a third rotary drive member is installed in the third robotic arm 24, and the third rotary drive member is a rotary motor or a pneumatic drive member. The third rotary drive member is transmission-connected to the gripper seat to drive the gripper seat to rotate. The main gripper and the auxiliary gripper are slidable along the gripper seat. When the main gripper and the auxiliary gripper are close to each other, they can clamp the object. When the main gripper and the auxiliary gripper are away from each other, they can release the object.

[0058] To avoid damaging the sample bottle during the clamping process, the main clamping jaw and the auxiliary clamping jaw are both made of silicone, or the clamping surfaces of the main clamping jaw and the auxiliary clamping jaw are respectively provided with a silicone layer.

[0059] The rheology station automated detection device also includes an industrial computer 70. The visual detection unit 50 includes a bracket 51 and a camera 52 arranged on the bracket 51. The bracket 51 is fixed to the operating table 10. The camera 52 is adjustably installed on the bracket 51. The test area 13 is located next to the bracket 51. The industrial computer 70 is communicatively connected to the camera 52.

[0060] The bracket 51 includes a horizontal beam and a vertical beam, the horizontal beam and the vertical beam are vertically fixedly connected, and the bottom end of the vertical beam is fixedly connected to the table top of the operating table 10. The camera 52 is mounted on the horizontal beam, thereby being suspended above the operating table 10. Optionally, the bracket 51 is a sheet metal part. In one embodiment, the height of the bracket 51 is adjustable. For example, the vertical beam includes a first beam body and a second beam body, the second beam body is inserted into the first beam body, the first beam body is fixedly connected to the operating table 10, and the second beam body is connected to the horizontal beam. The distance between the horizontal beam and the table top of the operating table 10 is adjusted by adjusting the depth of the second beam body inserted into the first beam body to adapt to the requirements of different installation heights of the camera 52.

[0061] The camera 52 is mounted on the bracket 51 in an adjustable position. For example, the camera 52 can be rotatably mounted on the bracket 51, allowing for quick adjustments during commissioning. Alternatively, the camera 52 can slide along the beam. During commissioning, the camera 52 is moved along the beam to a desired position and then secured to the beam using locking bolts.

[0062] The image information captured by the camera 52 is transmitted to the industrial computer 70, which performs analysis and processing and displays the final results. Optionally, the industrial computer 70 is a computer.

[0063] The test area 13 is provided with a waste paper chute 14, into which the robot 20 can deposit the test paper after the camera 52 completes its capture. Optionally, the waste paper chute 14 is in the shape of a square box. Alternatively, the robot 20 can directly deposit the discarded test paper into the chute 14 after the test paper is tested. The waste paper in the chute 14 is collected by the mobile robot 20 within the laboratory, or handled by a human operator.

[0064] Specifically, the waste paper trough 14 is located below the test paper auxiliary bracket 61 . When the first clamping plate 62 and the second clamping plate 63 move away from each other to release the test paper, the test paper falls directly into the waste paper trough 14 under the action of gravity.

[0065] Below the operating table 10 are a waste bucket and a cleaning bucket. A waste box 15 is located on the operating table 10, the bottom of which is connected to the waste bucket via a pipe. The cleaning bucket contains cleaning fluid for rinsing sample bottles, and a peristaltic pump 80 is connected to the cleaning bucket. The rheometer 30 has a rotor and a blow dryer is fixedly mounted on the rheometer 30, facing the rotor.

[0066] The waste box 15 is fixed on the operating table 10. The sample bottles to be tested used in the test paper test project can be the original packaging boxes. In this case, after the test paper test, the waste samples can be recovered through the waste box 15 or directly placed back in the sample area 12 to wait for recycling. The sample bottles used in the viscosity test project are standard bottles, and the waste samples need to be poured out and cleaned after the test. Therefore, after the viscosity test is completed, the waste samples in the sample bottles to be tested are poured into the waste box 15 by the robot 20 and transported to the waste bucket via a pipeline. The cleaning bucket contains clean water or other types of cleaning fluid. After the robot 20 pours the waste samples into the waste box 15, the peristaltic pump 80 injects the cleaning fluid into the sample bottle. To clean the rotor synchronously, the robot 20 places the sample bottle containing the cleaning fluid in the rheometer 30, moves the sample bottle upward to insert the rotor into the cleaning fluid, and the sample bottle and the rotor are cleaned synchronously by the rotation of the rotor. After cleaning, the robot 20 pours the waste water into the waste box 15. To ensure the cleaning effect, the above cleaning process can be repeated two or three times. The cleaned sample bottle is placed back into the sample area 12 by the robot 20 .

[0067] like Figure 2 and Figure 3 As shown, the peristaltic pump 80 is mounted on the first bracket 51, which is fixed to the operating table 10. After the rheometer 30 completes the test, the robot 20 pours the waste sample into the waste box 15 and moves the empty sample bottle under the peristaltic pump 80 to receive the cleaning solution. The peristaltic pump 80 is raised and fixed by the first bracket 51.

[0068] It should be noted that the test paper test project can also be tested using standard sample bottles. In this case, similar to the viscosity test project, after the test is completed, the robot 20 and the peristaltic pump 80 cooperate to wash the sample bottle with water multiple times.

[0069] A dryer is fixedly mounted on the rheometer 30 and is used to dry the rotor. In one embodiment, the dryer is a fan that promotes air flow and accelerates the drying of the rotor. In another embodiment, the dryer is a hair dryer that provides hot air to further accelerate the drying of the rotor.

[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
