Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, specifically to a fully automatic sample bottle cleaner. Background Technology

[0002] In the operation of various analytical instruments in the laboratory, precision analytical instruments such as liquid chromatographs, gas chromatographs, and ion chromatographs all require sample vials (e.g., 2ml). Considering factors such as cost, sample vials often need to be cleaned and reused after use. Currently, used sample vials are usually manually placed into a cleaning tank for cleaning. However, due to the small opening of the vials, it is difficult for the cleaning agent to naturally enter and completely clean them. Furthermore, for vials with caps, the caps must be opened one by one. In addition, some toxic chemicals inside the vials may pose a health hazard during the cleaning process. Therefore, given the characteristics of sample vials—small openings, large quantity, complex cleaning procedures, and high cleanliness requirements—the cleaning of sample vials has always been a challenge for all analytical testing personnel.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0044] like Figure 1 , 2 The fully automated sample vial cleaner shown includes a housing 1, a moving assembly 2, a gripping assembly 3, a capping assembly 4, a capping and discarding assembly 5, a liquid extraction assembly 6, a cleaning assembly 7, a waste liquid collection assembly 8, and a control box. The moving assembly 2, gripping assembly 3, capping assembly 4, capping and discarding assembly 5, liquid extraction assembly 6, cleaning assembly 7, and waste liquid collection assembly 8 are all located inside the housing 1. The control box can be located inside or outside the housing 1, but it is preferred to locate it inside the housing 1. A detailed description of each component follows.

[0045] like Figure 1As shown: The box body 1 includes a frame 10, which is a rectangular structure composed of multiple profiles assembled by screws and buckles. A protective plate 11 is provided on the outside of the frame 10. The protective plate 11 is composed of multiple rectangular plates connected to the frame 10 by screws to form a box-shaped structure. The protective plate 11 is used to isolate the inside and outside of the box body 1 and can protect the components inside the box body 1. One side of the box body 1 is open for placing or removing sample bottles from the box body 1. A door 12 is provided on one side of the opening of the box body 1. The door 12 is slidably connected to the frame 10 and has a handle 120 connected to it for easy opening and closing.

[0046] like Figure 2 As shown: The inside of the housing 1 is provided with a sample bottle placement area. In this embodiment, the sample bottle placement area is provided with a tray support 13. The tray containing the sample bottles is placed on the tray support 13. The moving component 2, the cap opening component 4, the cap throwing component 5, the cleaning component 7, and the waste liquid collection component 8 are distributed around the tray support 13.

[0047] The moving component 2 is used to drive the gripping component 3 and the liquid-collecting component 6 to move. The gripping component 3 and the liquid-collecting component 6 are connected to the moving component 2. It should be noted that the moving component 2 does not involve the inventive point of this utility model; it is sufficient to realize movement along the X-axis, Y-axis, and Z-axis. However, in this embodiment, an alternative implementation of the moving component 2 is provided:

[0048] like Figure 3As shown: The moving component 2 includes an X-axis drive mechanism 20, a Y-axis drive mechanism 21, a first Z-axis drive mechanism 220, and a second Z-axis drive mechanism 221. Specifically: the X-axis drive mechanism 20 and the Y-axis drive mechanism 21 are both horizontal moving axes, and are perpendicular to each other. Both ends of the X-axis drive mechanism 20 are connected to the frame 10 by screws. One end of the Y-axis drive mechanism 21 is slidably connected to the X-axis drive mechanism 20. The first Z-axis drive mechanism 220 and the second Z-axis drive mechanism 221 are vertical moving axes, that is, the first Z-axis drive mechanism 220 and the second Z-axis drive mechanism 221 are perpendicular to the X-axis drive mechanism 20 and the Y-axis drive mechanism 21, and are slidably connected to the Y-axis drive mechanism 21. The X-axis drive mechanism 20 is used to drive the Y-axis drive mechanism 21 to move back and forth along the direction of the X-axis drive mechanism 20. The Y-axis drive mechanism 21 is used to drive the first Z-axis drive mechanism 220 and the second Z-axis drive mechanism 221 to move back and forth along the direction of the Y-axis drive mechanism 21. The first Z-axis drive mechanism 220 and the second Z-axis drive mechanism 221 are respectively used to drive the components connected to the first Z-axis drive mechanism 220 and the second Z-axis drive mechanism 221 to move up and down. In this embodiment, the gripping component 3 is connected to the first Z-axis drive mechanism 220, and the liquid taking component 6 is connected to the second Z-axis drive mechanism 221.

[0049] It should be noted that the specific mechanisms and driving methods of the X-axis drive mechanism 20, Y-axis drive mechanism 21, first Z-axis drive mechanism 220 and second Z-axis drive mechanism 221 are existing technologies. For details, please refer to the moving axis mechanisms of existing CNC milling machines or CNC engraving machines.

[0050] An auxiliary axis mechanism is provided at the other end of the Y-axis drive mechanism 21. The auxiliary axis mechanism includes an auxiliary guide rail 222, which is arranged parallel to the X-axis drive mechanism 20. Both ends of the auxiliary guide rail 222 are connected to the frame 10. An auxiliary slider 223 is slidably connected to the auxiliary guide rail 222. The auxiliary slider 223 is connected to the other end of the Y-axis drive mechanism 21 through a connecting rod 224. When the X-axis drive mechanism 20 drives the Y-axis drive mechanism 21 to move, the auxiliary slider 223 will move along the auxiliary guide rail 222. The auxiliary axis mechanism is used to assist the movement of the Y-axis drive mechanism 21 and at the same time, bear part of the weight of the Y-axis drive mechanism 21, making the structure of this component more stable.

[0051] The gripping component 3 is used to transport the sample vial. It should be noted that the gripping component 3 does not involve the inventive point of this utility model; it is sufficient to achieve the gripping of the sample vial. However, in this embodiment, an alternative implementation of the gripping component 3 is provided:

[0052] like Figure 4As shown: The gripping assembly 3 includes a gripper body 30. The upper end 30 of the gripper body is connected to the first Z-axis drive mechanism 220 by screws. Two first grippers 31 are slidably arranged at the lower end of the gripper body 30. Two cylindrical gripping rods 32 are respectively arranged on the ends of the two first grippers 31 away from the gripper body 30. All four gripping rods 32 are vertically arranged, and the upper ends of the gripping rods 32 are respectively connected to the corresponding first grippers 31. The sides of the gripping rods 32 are provided with anti-slip textures to increase the friction between them and the sample vial. A drive component 33, such as a motor, is arranged at the end of the gripper body 30 away from the two first grippers 31. The gripper body 30 has a transmission structure (existing technology) inside. The transmission mechanism is connected to the drive component 33 and the two first grippers 31 respectively, so that the drive component 33 can drive the two first grippers 31 to move closer or further apart through the transmission structure, thereby driving the gripping rods 21 to move closer or further apart, that is, to grasp the sample vial. A position sensor 34 is provided on the side of the gripper body 30, which can sense the position of the first gripper 31 in real time, thereby facilitating precise control of the movement of the first gripper 31.

[0053] The cap-opening assembly 4 is used to open the cap of the sample injection bottle. It should be noted that the cap-opening assembly 4 does not involve the inventive point of this utility model; it is sufficient to enable the opening of the sample injection bottle. However, in this embodiment, one alternative implementation of the cap-opening assembly 4 is provided:

[0054] like Figure 5 As shown: The cap opening assembly 4 includes a transmission 40, a rotating component 41 rotatably connected to the transmission 40, and two grippers 42 movably connected to the rotating component 41. The two grippers 42 can move closer or apart, and the opposing surfaces of the two grippers 42 are both set with a V-shaped structure. A V-shaped flexible block is connected to each of the V-shaped structures to prevent the grippers 42 from damaging the sample vial and to increase the friction between the grippers and the sample vial. A position sensor 43 is provided on the rotating component 41 to sense the position of the grippers 42 in real time, thereby facilitating precise control of the movement of the grippers 42. A drive component 44, such as a motor, is connected to one side of the rotating component 41 on the transmission 40. The drive component 44 can drive the rotating component 41 to rotate through the transmission 40.

[0055] The cap-throwing assembly 5 is used to collect the caps opened by the cap-opening assembly 4. It should be noted that the cap-throwing assembly 5 does not involve the inventive point of this utility model; it is sufficient to achieve the collection of caps. However, in this embodiment, an alternative implementation of the cap-throwing assembly 5 is provided:

[0056] like Figure 6As shown: The cap-throwing assembly 5 includes a horizontally arranged support plate 50. A vertical support rod 51 is arranged between the support plate 50 and the housing 1. The lower end of the support rod 51 is connected to the housing 1 by screws, and the upper end of the support rod 51 is connected to the support plate 50 by screws. A horizontally arranged stop pin 52 is connected to the support plate 50. An optical sensor 53 is also arranged on the support plate 50 near the stop pin 52. The optical sensor 53 is used to detect the position of the cap. A barrel-shaped container 54 is arranged near the support rod 51. The container 54 is located below the stop pin 52. When the gripping assembly 3 grabs the cap and moves it above the container 54, the cap moves to below the stop pin 52. Then, the gripping rod 32 is spread apart to both sides, that is, the cap is released. At the same time, the gripping assembly 3 moves upward. At this time, the cap will fall into the container 54 under the action of gravity or under the push of the stop pin 52, which can prevent the cap from sticking to the gripping rod 32 due to static electricity or other reasons.

[0057] The liquid extraction component 6 is used to extract or discharge liquid from the sample vial. It should be noted that the liquid extraction component 6 does not relate to the inventive point of this utility model and can adopt a commonly used laboratory pipetting mechanism. However, in this embodiment, an alternative implementation of the liquid extraction component 6 is provided:

[0058] like Figure 7 As shown: The liquid extraction assembly 6 includes a plunger pump 60, which includes a plunger pump body 600. The plunger pump body 600 has multiple plunger chambers (four are shown as an example). Each plunger chamber has a plunger 601 that is sealed and slidably disposed therein. A drive component 61, such as a motor, is disposed at the upper end of the plunger 601. A mounting plate 62 is disposed between the drive component 61 and the plunger pump body 600. The upper and lower ends of the mounting plate 62 are respectively connected to the drive component 61 and the plunger pump body 600 by screws. The mounting plate 62 is connected to the second Z-axis drive mechanism 221 by screws. A drive block 63 is slidably disposed on the mounting plate 62. The upper ends of the multiple plungers 601 are all connected to the drive block 63. The drive block 63 is connected to the output shaft of the drive component 61. The drive component 61 drives the drive block 63 to move the plungers 601 in the plunger chamber.

[0059] A buffer mechanism is provided at the lower part of the plunger pump body 600. The buffer mechanism includes a buffer block 64, on which a buffer cavity is opened. A liquid storage cavity 640 is slidably arranged in each buffer cavity. A needle tube 65 is connected to the lower end of the liquid storage cavity 640. A spring 66 is arranged between the bottom surface of the buffer cavity and the liquid storage cavity 640. The two ends of the spring 66 abut against the bottom surface of the buffer cavity and the liquid storage cavity 610, respectively. When the needle tube 65 is subjected to force, the liquid storage cavity 640 can compress the spring 66 and slide into the buffer cavity, thereby protecting the needle tube 65. The side of the buffer block 64 is provided with a long strip-shaped through groove 641 corresponding to the buffer cavity. The through grooves 641 are distributed along the axial direction of the liquid storage cavity 640. A flexible tube 67 is installed through the through groove 641. One end of the flexible tube 67 is connected to the liquid storage cavity 640, and the other end of the flexible tube 67 is connected to the inside of the corresponding plunger cavity. When the plunger 601 moves, it can generate positive or negative pressure inside the liquid storage cavity 640 through the flexible tube 67, so that the liquid storage cavity 640 can draw or discharge liquid through the needle tube 65. The through groove 641 is provided so that when the liquid storage cavity 640 slides in the buffer cavity, the flexible tube 67 can slide in the through groove 641 and avoid interference between the flexible tube 67 and the through groove 641.

[0060] like Figure 2 As shown: The cleaning assembly 7 includes a cleaning tank 700 and a spraying mechanism. The spraying mechanism is positioned above the cleaning tank 700 and is used to spray cleaning agent or water onto the sample vials within the cleaning tank 700. Specifically:

[0061] like Figure 8 As shown: The cleaning tank 700 is equipped with a drain port 7000 and an overflow port 7001. The drain port 7000 is located at the bottom of the cleaning tank 700 and is used to drain the liquid in the cleaning tank 700. The drain port 7000 is connected to a pipe 7002. A pump body 7003 and a control valve 7004 are installed on the pipe 7002. In the figure, the pipe 7002 connects two lines, allowing for selective discharge. The pipe 7002 can be led out of the tank 1 to the outside for discharge. The overflow port 7001 is located at the top of the cleaning tank 700 and is used to maintain the liquid level in the cleaning tank 7000 to prevent liquid from overflowing from the cleaning tank 700.

[0062] The cleaning tank 700 is equipped with a cleaning tray 701 for placing sample vials. The cleaning tank 700 is an ultrasonic cleaning tank, and an ultrasonic transducer 702 is installed inside the cleaning tank 700. Ultrasonic waves emitted by the ultrasonic transducer 702 can clean the exterior of the sample vials, meeting the external cleanliness requirements of the sample vials.

[0063] The spraying mechanism includes a spray pipe 710, a pump body 711, and a pipeline 712. The spray pipe 710 is equipped with multiple nozzles 713, distributed along its length. Each nozzle 713 corresponds to a sample bottle on the cleaning tray 701, facilitating accurate spraying of cleaning agent or water into the sample bottle. Each nozzle 713 can spray cleaning agent or water into one sample bottle, and multiple nozzles 713 can spray multiple sample bottles simultaneously, improving cleaning efficiency. One end of the pipeline 712 is connected to the spray pipe 710, the pump body 711 is mounted on the pipeline 710, and the other end of the pipeline 712 can extend out of the housing 1.

[0064] In this embodiment, the spraying mechanism includes a first spraying mechanism 71a and a second spraying mechanism 71b. The other end of the pipe 712 in the first spraying mechanism 71a is used to connect to a cleaning agent source. When there are multiple cleaning agent sources (two are shown in the figure), a control valve 714 is also provided on the pipe 712 of the first spraying mechanism 71a to control the injection of different cleaning agents, such as... Figure 9 As shown. The other end of pipe 712 in the second spraying mechanism 71b is used to connect to a water source, as shown... Figure 10 As shown, two spraying mechanisms spray cleaning agent and water onto the sample vials respectively, meeting the internal cleanliness requirements of the vials.

[0065] In a preferred embodiment of this example: the cleaning assembly 7 further includes a moving mechanism, and the spray pipe 710 is connected to the moving mechanism. The moving mechanism is used to drive the spray pipe 710 to move above the cleaning tank 700. Through the moving mechanism, the spray pipe 710 can sequentially spray liquid to clean the sample bottles in the cleaning tank 700.

[0066] The following is a specific implementation method of the moving mechanism:

[0067] like Figure 11 , 12 As shown, the moving mechanism includes a movable base 720, a drive component 721, a pair of transmission wheels 722, and a synchronous belt 723. The movable base 720 is connected inside the housing 1. The drive component 721 (e.g., a motor), the pair of transmission wheels 722, and the synchronous belt 723 are connected to the movable base 720. The drive component 721 is connected to one of the transmission wheels 722. The synchronous belt 723 is fitted onto the pair of transmission wheels 722. The spray pipe 710 is connected to the synchronous belt 723. The drive component 721 drives the transmission wheels 722 to rotate, which in turn drives the synchronous belt 723 to move, thereby moving the spray pipe 710.

[0068] In this embodiment, the moving mechanism further includes a guide rail 724 and a slider 725. The guide rail 724 is connected to the moving base 720, and the slider is slidably connected to the guide rail 724. The spray pipe 710 is connected to the slider 725. When the spray pipe 710 moves, the guide rail 724 and the slider 725 provide stable guidance for the movement of the spray pipe 710.

[0069] In another preferred embodiment of this example: the cleaning assembly 7 further includes a floating mechanism, which is used to assist in observing and controlling the liquid level in the cleaning tank 700.

[0070] The following is a specific implementation method for a floating mechanism:

[0071] like Figure 8 As shown: The floating mechanism includes a liquid detection tank 730, a guide rod 731, a float 732, and a position sensor 733. The liquid detection tank 730 is connected to the cleaning tank 700, and the bottom height of the liquid detection tank 730 is not higher than the bottom height of the cleaning tank 700. In the illustration, the bottom height of the liquid detection tank 730 is slightly lower than the bottom height of the cleaning tank 700. The guide rod 731, float 732, and position sensor 733 are all located within the liquid detection tank 730. The float 732 is vertically movable and connected to the guide rod 731, allowing it to float and rise with the liquid level in the liquid detection tank 730. The position sensor 733 is located at the upper and lower parts of the guide rod 731, respectively, to sense the liquid level in the cleaning tank 700. Once cleaning begins in the cleaning tank 700, the liquid in the cleaning tank 700 will also flow into the liquid detection tank 730, and the liquid levels in both tanks will remain consistent. The liquid level is observed by the float 732 in the floating mechanism. If the position sensor 733 detects that the liquid level is too high, the control valve 7004 of the cleaning tank 700 can be opened to discharge a portion of the liquid.

[0072] like Figure 2 As shown, the waste liquid collection assembly 8 is used to collect the liquid extracted from the sample vial by the liquid collection assembly 6. The waste liquid collection assembly 8 mainly includes one or more waste liquid boxes 80.

[0073] A control box (not shown in the figure) is used to control the operation of each component. The control box can be located inside or outside the housing 1, but it is preferred to locate it inside the housing 1. The control box contains control circuits and components. The aforementioned moving component 2, gripping component 3, lid opening component 4, lid throwing component 5, liquid dispensing component 6, and cleaning component 7 are all electrically connected to the control box, which controls the operation of each of these components. A human-machine interface device 9 is located on the outside of the housing 1 and is connected to the housing 1. The user can issue control instructions to the control box through the human-machine interface device 9.

[0074] When cleaning is required: connect the tubing 7002 and 712 of the cleaning assembly 7; open the door 12 of the housing 1, place the tray containing the sample vials on the tray support 13, close the door 12, and start cleaning through the human-machine interface device 9.

[0075] The moving component 2, via the X-axis drive mechanism 20 and the Y-axis drive mechanism 21, moves the gripping component 3 to above a sample vial on the tray support 13. The first Z-axis drive mechanism 220 moves the gripping component 3 downward toward the sample vial, so that the gripping component 3 clamps the cap of the sample vial via the gripping rod 32. The moving component 3 moves the gripped sample vial to the cap opening component 4. The cap opening component 4 clamps the body of the sample vial via the gripper 42. The drive component 44 drives the rotating component 41 to rotate, so that the body of the vial and the cap rotate relative to each other, thereby completing the opening of the sample vial. The moving component 3 moves the gripping component 3 holding the cap to the cap discarding component 4 and puts the cap into the container 53. The moving component 3 returns to the cap opening component 4 and moves the gripping component 3 to grab the body of the opened sample vial, placing the body of the sample vial into the cleaning tray 701 of the cleaning pool 700. When the cleaning tray 701 is full of sample vials, cleaning begins.

[0076] The moving component 2 drives the liquid-taking component 6 to move above the sample bottle in the cleaning tank 700 via the X-axis drive mechanism 20 and the Y-axis drive mechanism 21. The second Z-axis drive mechanism 221 drives the liquid-taking component 6 to move downwards and inserts the needle 65 into the corresponding sample bottle. Under the action of the plunger pump 60, the test liquid / residual liquid in the sample bottle is drawn into the storage chamber 640. After the liquid is drawn, the moving component 2 drives the liquid-taking component 6 to move above the waste liquid box 80. The liquid-taking component 6 discharges the residual liquid in the storage chamber 640 into the waste liquid box 80. This step can be omitted when there is no test liquid / residual liquid in the sample bottle. The moving mechanism moves the spray pipe 710 of the first spraying mechanism 71a above the sample inlet tube, spraying cleaning agent into the inside and outside of the sample bottle through the nozzle 713. The ultrasonic transducer 702 is activated to clean the sample bottle with cleaning agent. After cleaning, the cleaning agent in the sample bottle is transferred to the waste liquid box 80 through the liquid taking component 6. The waste liquid in the cleaning tank 700 is discharged through the pipeline 7002. The cleaning agent cleaning can be performed several times. The moving mechanism then moves the spray pipe 710 of the second spraying mechanism 71b above the sample inlet tube, spraying water into the inside and outside of the sample bottle through the nozzle 713. The ultrasonic transducer 702 is activated to clean the sample bottle with water. After cleaning, the water in the sample bottle is transferred to the waste liquid box 80 through the liquid taking component 6. The water in the cleaning tank 700 is discharged through the pipeline 7002. The water cleaning can be performed several times until the bottle is clean.

[0077] After cleaning is complete, the moving component 2 drives the gripping component 3 to place the liquid inlet bottle on the cleaning tray 701 back into the tray on the tray support 13. Once all cleaning is complete, the door 12 is opened, the tray is removed, the waste liquid box 80 is emptied, and the entire cleaning process is completed automatically.
