Description

Technical Field

[0001] This utility model relates to the field of analytical testing technology, and in particular to a sample tube recovery device. Background Technology

[0002] In physical adsorption testing, samples are often housed in a long, thin test tube. Since this tube cannot stand stably and vertically on a plane, it must be placed on a test tube holder. For large-scale testing, especially automated testing, this not only requires multi-site positioning, resulting in a huge workload, but also occupies a significant amount of space. After testing, the sample tubes often need to be returned to the test tube holder or turntable, occupying testing stations, limiting the number of testing stations, and consequently, the efficiency of the testing.

[0003] To address the aforementioned problems, this invention proposes a sample tube recovery device. Utility Model Content

[0004] To solve the aforementioned technical problems, this utility model proposes a sample tube recovery device. This utility model adds a bearing assembly below the twisting mold, so that the original layered twisting molds are all mounted on the bearing assembly, making the twisting mold a single unit. When changing molds, the twisting mold and the bearing assembly can be replaced together. The technical solution of this utility model is implemented as follows:

[0005] A sample tube recovery device includes at least one storage chamber and at least one actuator assembly;

[0006] The storage chamber includes at least one one-way baffle and at least one one-way spring;

[0007] The storage chamber is provided with a recessed groove, which is used to support the spherical or cylindrical area of ​​the sample tube;

[0008] The one-way baffle is rotatably fixed to the upper edge of the storage chamber. One end of the one-way spring is fixed to the side of the storage chamber, and the other end is connected to one end of the one-way baffle through an arc-shaped component. A support column is provided below the arc-shaped component.

[0009] The minimum distance between the one-way baffle and the storage chamber is at least greater than the standard diameter of the spherical or cylindrical region of a sample tube;

[0010] The actuator assembly includes a first actuator and a fixed structure;

[0011] The fixing structure is located on the outside of the storage chamber;

[0012] The first actuator includes an execution part and a power part;

[0013] The first actuator is fixed to the outside of the fixed structure, and the actuator is retractably connected to the power part and driven by the power part.

[0014] Preferably, the storage chamber includes two recesses.

[0015] Preferably, in the actuator assembly, the number of the first actuators is at least two.

[0016] Preferably, the groove is inclined.

[0017] Preferably, it further includes a second actuator;

[0018] The number of storage rooms is at least two floors;

[0019] The second actuator is positioned below the fixed structure.

[0020] Preferably, at least three first actuators are provided on the side of the storage chamber; wherein at least one actuator is located at the center of the side of the storage chamber.

[0021] The advantages of this utility model are as follows:

[0022] An external robotic arm places the completed sample tube between the actuator and the one-way baffle. The actuator extends under the control of the power unit, pushing the sample tube to open the one-way baffle and enter the storage chamber. The spherical area of ​​the sample tube falls into the groove, which can reduce the thickness of the storage chamber as much as possible and facilitate the sample tube to roll along the predetermined position. After the sample tube is placed, the actuator retracts, and the one-way baffle returns to its original state under the action of the one-way spring and the arc-shaped component, that is, the state of closing the storage chamber. This effectively prevents the sample tube from sliding out of the storage chamber.

[0023] In this utility model, both the actuator and the second actuator are commercially known power components. They can be lead screw structures with motors, or cylinders, electric cylinders, etc. This utility model does not impose any restrictions on them. Attached Figure Description

[0046] The embodiments of the present invention will be described in more detail below through examples. It should be noted that the embodiments of the present invention are not limited to these examples.

[0047] In a specific embodiment 1, such as Figure 1 As shown, a sample tube recovery device includes a storage chamber 1 and an actuator assembly.

[0048] The actuator assembly includes two actuators and a fixed structure.

[0049] Storage chamber 1 includes a one-way baffle 3 and a one-way spring 4;

[0050] The storage chamber 1 is provided with a recessed groove 5, which is used to support the spherical area of ​​the sample tube.

[0051] One-way baffle 3 is rotatably fixed to the upper edge of storage chamber 1. One end of one-way spring 4 is fixed to the side of storage chamber 1, and the other end is connected to one end of one-way baffle 3 through arc-shaped piece 6. A bearing column 7 is provided below arc-shaped piece 6.

[0052] The minimum distance between the one-way baffle 3 and the storage chamber 1 is at least greater than the standard diameter of the spherical region of a sample tube;

[0053] The first actuator 2 includes an actuation part 2-1 and a power part 2-2;

[0054] The first actuator 2 is fixed to the outside of the fixed structure 9, which is located on the outside of the storage chamber 1. The actuator 2-1 is retractably connected to the power unit 2-2 and driven by the power unit 2-2.

[0055] In this embodiment, the bearing column 7 serves as the rotation fulcrum of the arc-shaped component 6, and the arc-shaped component 6 provides the torque for the one-way baffle 3 to return to its original shape under the action of the one-way spring 4.

[0056] The specific usage process of this embodiment is as follows:

[0057] The completed sample tube is placed between the execution part 2-1 of the first actuator 2 and the one-way baffle 3 by an external robotic arm or manual operation.

[0058] Subsequently, the power part 2-2 of the first actuator 2 controls the execution part 2-1 to extend, and the execution part 2-1 pushes the sample tube to open the one-way baffle 3 and enter the storage chamber 1, and the spherical area of ​​the sample tube falls into the groove 5.

[0059] After the sample tube is pushed between the one-way baffle 3 and the storage chamber 1, the power part 2-2 of the first actuator 2 controls the actuator part 2-1 to retract, and the one-way baffle 3 will also return to its original state, that is, the state of sealing the storage chamber 1. This can effectively prevent the sample tube from sliding out of the storage chamber 1. The specific process is as follows: when the one-way baffle 3 is lifted by the actuator part 2-1, it will stretch or compress the one-way spring 4 along with the arc-shaped part 6. When the actuator part 2-1 retracts, the tendency of the one-way spring 4 to return to its original state will drive the one-way baffle 3 to return to its original state.

[0060] In this embodiment, when the one-way baffle 3 is opened, the end point in contact with the one-way spring 4 will rotate, causing the arc-shaped part 6 to rotate, thereby stretching the one-way spring 4.

[0061] In other embodiments, it can also be configured to compress a one-way spring 4. This invention does not impose any limitations on this; it is simply an application of spring compression spring.

[0062] Once storage chamber 1 is full of sample tubes, it can be moved away by manual or machine handling, thus completing the use of this embodiment.

[0063] In some preferred embodiments, the storage chamber 1 includes two recesses 5.

[0064] The purpose of the two grooves 5 is to increase the density of sample tubes placed in a single storage chamber 1. Because the diameter of the spherical region of the sample tube is larger than the diameter of the tube body, the two grooves 5 are staggered to place the sample tubes, thus making better use of space.

[0065] In some preferred embodiments, the number of first actuators 2 is at least two.

[0066] Compared to a single first actuator 2, two first actuators 2 push the sample tube, so that the sample tube is less likely to tilt when sliding.

[0067] In some preferred embodiments, the groove 5 is inclined.

[0068] The slightly inclined groove 5 allows the sample tube to roll automatically to the bottom after entering the storage chamber 1, thus preventing the sample tube from sliding out of the storage chamber 1 automatically.

[0069] Of course, to avoid the sample tube sliding too fast, the tilt angle should not exceed 30 degrees, so that the sample tube can slide smoothly to the bottom.

[0070] In a specific embodiment 3, such as Figure 3 As shown, a sample tube recovery device includes two storage chambers 1 and an execution component.

[0071] The execution components include three first actuators 2, two second actuators 8, and a fixed structure 9.

[0072] The first actuator 2 is fixed on the outside of the fixed structure 9, located at the front end, rear end and middle of the fixed structure 9 respectively.

[0073] The second actuator 8 is fixed below the fixed structure 9, which is located on the outside of the storage chamber 1.

[0074] In this embodiment, each storage chamber 1 includes a one-way baffle 3 and a one-way spring 4.

[0075] In this embodiment, the storage chamber 1, the first actuator 2, the second actuator 8, the one-way baffle 3, and the one-way spring 4 are completely identical in structure and function to those in embodiment 2. The only difference is that in this embodiment, a first actuator 8 is also provided in the center of the side of the fixed structure. The advantage of this design is that when the sample tube is placed, the tube body first contacts the execution part of the first actuator 8 in the middle, and then the first actuator in the middle retracts, allowing the sample tube to fall between the fixed structure 9 and the storage chamber. This effectively prevents the sample tube from breaking due to excessive tilting speed.

[0076] It should be noted that the execution part of the first actuator 8 in the middle is slightly extended in the initial stage, such as... Figure 3 The state shown is different from the retracted state of the other two first actuators 8.

[0077] It should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
