In the description of the present invention, unless explicitly defined otherwise, terms such as arrangement, installation, connection, etc. should be construed broadly and the specific meaning of the terms in the present invention can be reasonably determined by a person skilled in the art in combination with the specific contents of the technical scheme.

In the description of the present invention, the descriptions of the terms "one embodiment," "some embodiments," "illustrative embodiments," "examples," "specific examples," or "some examples," etc., mean that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the present invention. In this specification, schematic representations of the above terms do not necessarily refer to the same embodiments or examples. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

Referring to fig. 1, a sample is generally placed in a sample container 200 for dispensing, and the sample container 200 is closed by a container cover 300 in order to prevent the sample in the sample container 200 from overflowing during dispensing to cause contamination. The connection between the container lid 300 and the sample container 200 is typically made by threads, i.e. the container lid 300 can be separated from the sample container 200 by rotating and axially moving relative to the sample container 200. On the other hand, in order to facilitate stable placement of the sample containers 200, the sample containers 200 are generally placed in the sample rack 400, and in particular, the sample rack 400 is provided with one or more insertion holes 410 for placing one or more sample containers 200, and when a plurality of insertion holes 410 are provided, the plurality of insertion holes 410 may be arranged side by side along a straight line.

The separated container cover 300 may carry samples with it, with the potential for contamination, and thus the container cover 300 may need to be placed in a designated location, such as a dedicated collection container. In a common layout situation, the clamping mechanism (e.g. a manipulator) for clamping the container cover 300 on the cover removing device is disposed along a vertical direction with the collection container, specifically, the clamping mechanism is disposed above, and the collection container is disposed below, so that when the container cover 300 is separated from the sample container 200, the container cover 300 can fall into the collection container under the action of gravity. Because the clamping mechanism and the collecting container are placed up and down, the clamping mechanism and the collecting container occupy a certain height space, and in certain practical application situations, such as a limited-height situation, or on the premise that the overall size of the sample pretreatment apparatus is not changed, when the cap removing device is integrated in the sample pretreatment apparatus, the height of the collecting container needs to be reduced, however, when the height of the collecting container is reduced, the internal space of the collecting container is reduced, the corresponding storage capacity is reduced, and the cleaning frequency of a user is increased.

Referring to fig. 2 and 3, the sample pretreatment apparatus according to the embodiment of the present invention mainly includes a cap removing device 100, a collecting container 500, and a sample loading device, wherein the cap removing device 100 is used for removing caps from capped sample containers 200, the collecting container 500 is used for collecting separated container caps 300, and the sample loading device is used for dispatching capped sample containers 200 to the cap removing device 100 for removing caps, which will be described in detail below with reference to the accompanying drawings.

The cap removing device 100 includes a first clamping mechanism 110, where the first clamping mechanism 110 is used to clamp the container cap 300 and can cooperate with other mechanisms to perform separation of the container cap 300, for example, the sample container 200 is inserted into and fixed in the sample rack 400, and the first clamping mechanism 110 rotates around a vertical axis after clamping the container cap 300 and drives the container cap 300 to synchronously move upwards, so that separation of the container cap 300 can be achieved. Still alternatively, referring to fig. 3 and 4, the cap removing apparatus 100 may further include a second clamping mechanism 120, where the second clamping mechanism 120 is used to clamp the sample container 200, and the first clamping mechanism 110 and the second clamping mechanism 120 are cooperatively used to separate the container cap 300, specifically, the first clamping mechanism 110 and the second clamping mechanism 120 each include clamping members for clamping, which are named as a first clamping member 111 and a second clamping member 121 for convenience of description, and the clamping members of the corresponding clamping mechanisms are adjusted according to different clamping positions, for example, the clamping members may include clamping jaws, and the first clamping mechanism 110 includes at least two first clamping jaws, and since there is no other member above the container cap 300, the first clamping jaws are disposed along a vertical direction, so that the first clamping jaws can move downward from above the container cap 300 to clamp the container cap 300. The second clamping mechanism 120 comprises at least two second clamping jaws, which are arranged in a horizontal direction, so that the second clamping jaws can move in the horizontal direction to clamp the sample container 200, avoiding interference with the container cover 300 and the first clamping mechanism 110. With the above configuration, the first clamping mechanism 110 and the second clamping mechanism 120 are arranged in parallel in the substantially horizontal direction as a whole. Of course, the number of clamping jaws is not limited to two, but may be three or another number to more stably clamp the container cover 300 or the sample container 200. The clamping driving mechanism for driving the clamping jaw to open and close can comprise a motor, an electric push rod, an air cylinder and other power elements.

The relative movement between the first clamping member 111 and the second clamping member 121 to achieve separation of the container cap 300 from the sample container 200 includes various situations, for example, when the container cap 300 is directly inserted into the sample container 200, the first clamping member 111 and the second clamping member 121 can achieve separation of the container cap 300 from the sample container 200 directly through relative movement in the vertical direction, and when the container cap 300 is screw-coupled with the sample container 200, the first clamping member 111 and the second clamping member 121 can achieve separation of the container cap 300 from the sample container 200 through relative rotation and relative movement in the vertical direction. Further, the first clamping member 111 and the second clamping member 121 may move either one or both, while the other is kept from being used. For example, when the container cover 300 is directly plugged into the sample container 200, the first clamping member 111 may drive the container cover 300 to move upwards, the second clamping member 121 may drive the sample container 200 to move downwards, or the first clamping member 111 may drive the container cover 300 to move upwards, and the second clamping member 121 may drive the sample container 200 to move downwards. For example, when the container cover 300 is screwed to the sample container 200, the first clamping member 111 may drive the container cover 300 to move upwards and rotate, the second clamping member 121 may drive the sample container 200 to rotate and move downwards, the first clamping member 111 may drive the container cover 300 to rotate, and the second clamping member 121 may drive the sample container 200 to move downwards.

Referring to fig. 2 and 3, the collection container 500 may be a collection box which is vertically disposed with a cavity for storing the container cover 300 therein, and the collection container 500 has an opening 510 for the container cover 300 to enter, and the opening 510 is located at the top end of the collection container 500, for example, at the upper surface of the collection container 500 so that the container cover 300 falls under the force of gravity. In this embodiment, the collection container 500 is located on one side of the cap removing device 100 along the horizontal direction, compared with the manner of placing the collection container 500 up and down, the collection container 500 does not need to be lowered due to avoiding the cap removing device 100, so that the collection container 500 can maintain a larger storage space, specifically, when the container cap 300 is in a state of just being separated from the sample container 200 and being clamped by the first clamping mechanism 110, the lowest position (for example, the lower edge of the container cap 300) of the container cap 300 is defined as the reference position at this time, and the height of the opening 510 is higher than the reference position, that is, the collection container 500 is not limited by the cap removing device 100, and can be lifted under the allowable condition, so as to increase the storage capacity and reduce the cleaning frequency of the user.

The sample loading device is capable of deploying capped sample containers 200 to the uncapping device 100 for uncapping processing, and in some embodiments, the sample loading device includes a front track portion and a sample introduction (SDM) portion, the SDM portion including a vertically and/or horizontally movable deployment mechanism, such as a deployment cart, for carrying sample containers 200 or sample racks 400 carrying sample containers 200, by which the sample containers 200 or carrying sample containers 200 can be moved from a loading area to the uncapping device 100.

Based on the above structure, since the opening 510 of the collection container 500 is higher than the lowest position of the container cover 300 after separation, the storage amount of the collection container 500 can be increased, and the frequency of cleaning the collection container 500 by the user can be reduced.

In order to achieve the transfer of the container cover 300 to the collection container 500, the present invention proposes various transfer schemes, and in some embodiments, the sample pretreatment apparatus further includes a transfer device, and the transfer device 600 is capable of driving at least the separated container cover 300 to move upward, thereby allowing the container cover 300 to reach a cover throwing position, where the container cover 300 can enter the collection container 500 through the opening 510, that is, the present embodiment is provided with a separate transfer device, and since the transfer of the container cover 300 and the separation of the container cover 300 are implemented by different mechanisms, the cover removing device 100 can perform the separation of the next container cover 300 when the transfer mechanism transfers the container cover 300, thereby enabling the reduction of waiting time and the improvement of efficiency. In addition to the upward movement, the transfer device 600 may be capable of driving the container cover 300 to perform various movements such as horizontal movement or rotation.

For example, the transfer device can previously drive the container cover 300 to move in the horizontal direction and then drive the container cover 300 to move upward to reach the above-described cap throwing position. When the first clamping mechanism 110 releases the container cover 300, the container cover 300 will descend under the action of gravity, so the transfer device needs to receive the container cover 300 under the first clamping mechanism 110, and based on this, the transfer device drives the container cover 300 to move in the horizontal direction, so that the container cover 300 deviates from the lower side of the first clamping mechanism 110, and interference with the first clamping mechanism during the upward movement of the container cover 300 is avoided. Of course, the first clamping mechanism 110 may also be moved or rotated along the horizontal direction to avoid the container cover 300, and the transferring device drives the container cover 300 to move upwards to reach the cover throwing position.

Based on the above-described concept, referring to fig. 6 in combination with fig. 2 and 3, the arrows in fig. 6 indicate the movement directions of the first transfer member 610 and the second transfer member 710 when performing the transfer operation, respectively, the sample pretreatment apparatus further includes a first transfer device 600 and a second transfer device 700, the first transfer device 600 includes the first transfer member 610, and the first transfer member 610 can move in the horizontal direction, and can receive the container cover 300 released by the first clamping mechanism 110 and can drive the container cover 300 to move in the horizontal direction when moving below the first clamping mechanism 110, for example, when moving to the position shown in fig. 6. The second transfer device 700 includes a second transfer member 710, where the second transfer member 710 is capable of moving in a vertical direction, and when the second transfer member 710 moves downward to a start point of the travel, the first transfer member 610 can transfer the container cover 300 thereon to the second transfer member 710, and then the second transfer member 710 drives the container cover 300 to move upward to an end point of the travel, so as to reach a cover throwing position. In this embodiment, two transfer devices are provided, which can move independently, for example, when the second transfer member 710 moves up one container cover 300, the first transfer member 610 can be reset in advance to receive the next container cover 300, so that waiting time can be reduced and efficiency can be improved.

The first transfer element 610 and the second transfer element 710 may be containers having sides that define a cavity, or may be flat panel load bearing structures, such as receiving plates, strips, etc.

As a specific implementation of the first transfer device 600, referring to fig. 7 and 8, the first transfer device 600 mainly further includes a first driving mechanism 620 and a base 630, where the first driving mechanism 620 and the first transfer member 610 are connected to the base 630, and the first driving mechanism 620 drives the first transfer member 610 to move in a horizontal direction and flip around a horizontal axis.

The base 630 serves as a main bearing mechanism and may be, for example, a metal bracket as shown in the drawing, so that the base 630 has sufficient strength. The first driving mechanism 620 is connected to the base 630, the first transferring member 610 is connected to the first driving mechanism 620 and the base 630, and the first transferring member 610 can move between a start point and an end point of the stroke and can turn around a horizontal axis to switch between a first posture and a second posture under the driving of the same first driving mechanism 620, wherein the start point of the stroke (such as the position shown in fig. 7) is a cap receiving position, which is generally located below the cap removing device, and the end point of the stroke is a dumping position, which is deviated from the start point of the stroke in a horizontal direction. The first transfer member 610 in the first posture (for example, the posture shown in fig. 6) is disposed horizontally, and the first transfer member 610 in the second posture is inclined with respect to the horizontal plane. When the first transfer member 610 is at the stroke start point and in the first posture, the container cover 300 separated from the sample container 200 can be received and the container cover 300 can be held in the first transfer member 610; when the first transfer member 610 is at the end of the travel and in the second posture, the container cover 300 can slide out of the first transfer member 610 and fall into the second transfer member 710 under the action of gravity, thereby realizing the transfer of the container cover 300 between the first transfer member 610 and the second transfer member 710.

Based on the above, the first transfer member 610 is driven to move between different positions and turn around the horizontal axis by the first driving mechanism 620 in this embodiment, which can simplify the structure of the cover receiving device and help to reduce the cost. On the other hand, after the first transfer member 610 receives the container cover from the lower side of the first clamping mechanism 110, if the first transfer member 610 is directly turned over to topple over, the first transfer member 610 may touch the first clamping mechanism 110, so that a corresponding lifting mechanism needs to be provided to avoid, but this also increases the complexity of the apparatus, and affects the working efficiency, and the first transfer member 610 of the present embodiment receives the container cover at the start point of the travel and topples over the container cover at the end point of the travel, so that the topple over position avoids the cap removing device, and no additional lifting mechanism needs to be provided.

Note that, the terms "vertically disposed", "horizontally disposed", "vertical disposed" and "horizontally disposed" in this embodiment are used to describe the general posture of a single member, or the general positional relationship between a plurality of members, and are not strictly limited to an absolute horizontal or absolute arrangement, and may be referred to as a horizontal arrangement even if the first transfer member 610 has a certain inclination angle with respect to the horizontal plane.

To enable a driving mechanism to synchronously drive the first transfer member 610 to move in the horizontal direction and to turn over, in some embodiments, referring to fig. 7 and 8, the first driving mechanism 620 includes a first output portion 622, where the first output portion 622 is configured to output power, and may be a separate component or part of a device. In the present embodiment, the first output portion 622 is movable in the vertical direction. The first driving mechanism 620 further includes a first link 623, and the first link 623 is inclined with respect to the horizontal plane, and has one end (e.g., an upper end) rotatably connected to the first output portion 622 and the other end (e.g., a lower end) rotatably connected to the first transfer member 610. When the container cover 300 falls into the first transfer member 610 by gravity, the first output portion 622 moves upward, and the upper end of the first link 623 moves upward, and the lower end pulls the first transfer member 610, so that the first transfer member 610 moves in a direction approaching the first output portion 622 (e.g., a direction toward the right in the drawing), on the one hand, and the first transfer member 610 turns over toward the first output portion 622, on the other hand. When turned right to the limit state, the container cover 300 slides down by gravity.

In the above process, the movement and the turning of the first transfer member 610 are performed synchronously, that is, when the first transfer member 610 moves to the end of the stroke, the first transfer member 610 is just in the second posture capable of tilting the container cover 300, and when the first transfer member 610 moves to the start of the stroke, the first transfer member 610 is just in the first posture capable of receiving the container cover 300, so that when the first transfer member 610 receives the container cover 300 and starts to move to the right, although the first transfer member 610 is still under the first clamping mechanism 110, the turning angle of the first transfer member 610 is smaller, and the highest position thereof is still lower than the lowest position of the first clamping mechanism 110, without interference; when the first transfer member 610 continues to move rightward, the turning angle of the first transfer member 610 becomes larger, and the highest position of the first transfer member 610 rises so as to be possibly higher than the lowest position of the first clamping mechanism 110, but at this time, the first transfer member 610 and the first clamping mechanism 110 have been staggered in the horizontal direction, so that interference is not caused yet. The distance between the first transferring member 610 and the first clamping mechanism 110 may be set according to the above effect, so that interference between the first transferring member 610 and the first clamping mechanism 110 can be avoided, and the distance between the first transferring member 610 and the first clamping mechanism 110 along the vertical direction can be reduced, so that the structure is more compact. In addition, since the first transfer member 610 does not interfere with the first clamping mechanism 110, other operations can be performed immediately after the first clamping mechanism 110 releases the container cover 300, and thus work efficiency can be improved.

Of course, the first driving mechanism 620 may be an electric cylinder or an electric push rod.

It should be noted that, in the above first transfer device 600, the first transfer member 610 is driven to move and turn by one power source, and it should be noted that a plurality of driving force sources may be provided in the first transfer device 600, one driving the first transfer member 610 to move in the horizontal direction, and the other driving the first transfer member 610 to turn.

The embodiment of the present invention also proposes a first transfer device 600 for transferring the container cover 300 based on another concept, the first transfer device 600 also includes a first transfer member 610 and a first driving mechanism 620, the first driving mechanism 620 can drive the container cover 300 to move in a horizontal direction through the first transfer member 610, and when the container cover 300 is positioned at the end of a stroke, it can drop from the second transfer member 710.

Based on the above-mentioned concept, in some embodiments, the first transferring member 610 can both carry the container cover 300 and drive the container cover 300 to move in the horizontal direction, and as shown in fig. 10, the first transferring member 610 may be a conveyor belt, which is wound around a conveyor wheel, and the conveyor belt may continuously move along with the rotation of the conveyor wheel. One end of the conveyor belt is located below the first clamping mechanism 110, and the other end extends toward the second transfer member 710 to a position close to the second transfer member 710. After the first clamping mechanism 110 releases the container cover 300, the container cover 300 falls onto the conveyor belt under the action of gravity, is then driven by the conveyor belt to move rightward, and when it moves to the end of the stroke, i.e., the right end of the conveyor belt, it continues to move rightward and separate from the conveyor belt under the action of inertia, and finally falls into the second transfer member 710.

When the second transfer member 710 is a flat plate-shaped bearing structure, the bearing surface of the second transfer member may be lower than or flush with the bottommost end of the container cover 300, so that the container cover 300 can smoothly fall onto the second transfer member 710.

In other embodiments, the first transferring member 610 is only used to drive the container cover 300 to move horizontally, the container cover 300 is supported by other structures, and as shown in fig. 12, the first transferring device includes a supporting member 640, the supporting member 640 has a bearing surface with a low friction coefficient, the supporting member 640 is located below the first clamping mechanism 110, the first transferring member 610 may be a push rod or a push block capable of moving horizontally, and the height of the first transferring member 610 from the bearing surface should be smaller than the height of the container cover 300. After the first clamping mechanism 110 releases the container lid 300, the container lid 300 falls onto the support 640 under the force of gravity, and then the first transfer member 610 pushes the container lid 300 to move rightward until the end of the stroke falls into the second transfer member 710.

In the following description of the second transfer device 700 with reference to the drawings, for the purpose of saving power, in some embodiments, referring to fig. 2, the second transfer device 700 includes a second driving mechanism 720, where the second driving mechanism 720 is connected to the second transfer member 710, and is capable of driving the second transfer member 710 to move in a vertical direction to transport the container cover 300 to the cover throwing position, and driving the second transfer member 710 to turn around a horizontal axis to pour the container cover 300 into the collection container 500.

In this embodiment, the first transfer member 610 and the second transfer member 710 are driven by a single driving source, so that the number of driving sources can be reduced, the structure can be simplified, and the cost can be reduced. Meanwhile, the first transfer member 610 and the second transfer member 710 both transfer the container cover 300 in a turnover manner, and occupy less space in a vertical direction than in a transfer manner in which the container cover 300 naturally falls from the blanking port. In addition, the first output part 622 of the first driving mechanism 620 and the second output part 722 of the second driving mechanism 720 both move along the vertical direction, so that the first driving mechanism 620 and the second driving mechanism 720 can both be arranged along the vertical direction, and the space occupied in the horizontal direction is less, and the structure is compact.

In addition, by adjusting the orientation of the outlet 820, the installation position of the second transfer device 700 may be adjusted, as shown in fig. 7, the first transfer member 610 is moved in the left-right direction, and the first transfer device 600 and the second transfer device 700 are placed in the front-rear direction, and the sliding-out direction of the container cover 300 may be changed by the adapter 800.

In a specific embodiment, the first clamping mechanism 110 includes a vertical driving mechanism and a horizontal driving mechanism, where the vertical driving mechanism drives the horizontal driving mechanism and the first clamping member 111 to move in a vertical direction, and the horizontal driving mechanism drives the first clamping member 111 to move in a horizontal direction, or the horizontal driving mechanism drives the vertical driving mechanism and the first clamping member 111 to move in a horizontal direction, and the vertical driving mechanism drives the first clamping member 111 to move in a vertical direction.

Based on the above structure, the first clamping mechanism 110 may drive the container cover 300 to move upwards and horizontally to reach the cover throwing position, where the container cover 300 may enter the collection container 500 through the opening 510, for example, after the container cover 300 is separated from the sample container 200, the vertical driving mechanism drives the first clamping member 111 and the container cover 300 to move upwards until the bottommost end of the container cover 300 is higher than the opening 510 of the collection container 500, then the horizontal driving mechanism drives the first clamping member 111 and the container cover 300 to move horizontally to above the opening 510, finally the first clamping member 111 releases the container cover 300, and the container cover 300 falls into the collection container 500 under the action of gravity.

In another implementation, the first clamping mechanism 110 includes a vertical driving mechanism and a rotary driving mechanism, where the vertical driving mechanism can drive the rotary driving mechanism and the first clamping member 111 to move along a vertical direction, and the rotary driving mechanism drives the first clamping member 111 to rotate around a vertical axis, where the vertical axis is parallel to a rotation axis in a separation process of the container cover 300, and is arranged at intervals, in other words, the first clamping member 111 and the container cover 300 can both rotate around the rotation axis to separate the container cover 300 from the sample container 200 and revolve around the vertical axis, and a rotation track at this time is an arc with the vertical axis as a center, and a distance between the vertical axis and the rotation axis is a radius.

In the embodiment of the present invention, the sample pretreatment apparatus is integrated with the cap removing device 100, and compared with the cap removing device 100 which is separately arranged, a user does not need to separately configure the cap removing device 100, and the sample container 200 can be dispatched between the cap removing device 100 and the loading area through the sample loading device of the sample pretreatment apparatus, so that the step of transferring the sample container by the user is omitted. Specifically, the sample pretreatment apparatus is provided with a housing, and the decapping device 100 is installed inside the housing.

The sample preprocessing apparatus may be divided into an upper layer provided with a loading area in which a user can place the sample container 200 to be processed, and a lower layer including a plate for placing the sample container 200 therein. In some embodiments, the capping device 100 and the collection container 500 are both located at the lower layer of the sample pretreatment apparatus, i.e. below the loading area, and the structure of the upper layer is not increased, meanwhile, since the collection container 500 is placed at one side, and the opening of the collection container 500 is higher than the lowest position of the container cap 300 after separation, the storage amount of the collection container 500 can be ensured, and the height of the lower layer is not increased, so that the integration of the capping device 100 can be realized without changing the volume of the original apparatus.

It should be noted that, the decapping device 100 is located under the loading area, and only the height relationship between the two is shown, and should not be construed as being located directly under the loading area.

Since the decapping device 100 is lower than the loading area, the sample loading device of the present embodiment can drive the sample container 200 or the sample rack 400 to move up and down, thereby achieving the scheduling of the sample container 200 or the sample rack 400 between the loading area and the decapping device 100. In some embodiments, the loading area may also be used to place the post-processing sample container 200, with the loading area having a corresponding plurality of areas, with a partial area for placing the pre-processing sample container 200 and a partial area for placing the post-processing sample container 200.
