In one embodiment, referring to fig. 1 to 5, the sample transfer mechanism includes a supporting member 10, a carrying member 20, a transmission member 30 and a driving member 40, which are described below.

Referring to fig. 1 to 5, the supporting member 10 is mainly used as a structural assembly carrier of the entire conveying mechanism, such as to implement the assembly of the entire conveying mechanism on the machine body assembly, so as to facilitate the disassembly and assembly maintenance of the entire conveying mechanism; the driving member 40 is fixed to the supporting member 10, and the transmission member 30 is rotatably mounted to the supporting member 10 relative to the supporting member 10.

The support member 10 is provided with a first guiding portion a at a lower side of the transmission member 30, the first guiding portion a is a notch structure distributed through the support member 10 along a first direction (of course, it may be a structure similar to a blind hole or a blind groove, that is, it is arranged through a side surface of the support member 10), the notch structure extends along a preset arc path, the axial line of the preset arc path and the rotation axis of the transmission member 30 are located at the same side of the notch structure, so that one end of the notch structure is arranged close to (or adjacent to) the rotation axis of the transmission member 30, and the other end is arranged away from the rotation axis of the transmission member 30, and the groove surface facing the transmission member 30 by using the notch structure can be used as a guiding surface of the first guiding portion a (that is, the guiding surface extends along the preset arc path).

In other embodiments, the supporting member 10 may be omitted, and the structure of the body assembly is optimized such that a partial structure thereof can function as the supporting member 10, or the driving member 30, the driving member 40, the supporting member 40, and the like are directly assembled to the body assembly in a predetermined combination connection relationship.

Referring to fig. 1 to 5, the carrier 20 is mainly used as a carrier and a transfer carrier for the sample container a, and the movement or stop effect of the carrier 20 between the sampling position and the lofting position is realized by adjusting and controlling the movement position of the carrier 20, so that the sample container a can be transferred into and out of the accommodating space. In general, in order to perform the sampling operation smoothly, the carrier 20 should be able to keep the sample container a in an upright posture (i.e., the sample container a is perpendicular to the horizontal plane in the second direction or the up-down direction) when moving to the sampling position, so the structural form of the carrier 20 will be described below with the carrier 20 in the sampling position.

The carrier 20 includes a bearing portion 21 and a coupling portion 22 sequentially arranged in the second direction or the up-down direction; the connecting part 22 has two ends which are distributed oppositely up and down along the length direction, the bearing part 21 is fixedly arranged at the top end of the connecting part 22, the bottom end of the connecting part 22 is provided with a second guide part b which is matched with the first guide part a, the second guide part b comprises a guide wheel and other components (such as a shaft rod, a bearing and the like) which are used for introducing and needing, the guide wheel is arranged at the bottom end of the bearing part 20 in a manner of rotating relative to the bearing part 20, the rotating axes of the guide wheel are distributed along the first direction, so that the guide wheel can be embedded in the notch structure in an inserting manner, and the outer peripheral surface of the guide wheel can be abutted and contacted with the guide surface of the first guide part a; during the process of the driven movement of the carrier 20, the guide wheel can be rotationally moved along a preset arc path by the abutting contact relationship between the guide wheel and the guide surface, so that the movement stroke or movement track of the carrier 20 and the associated components is changed.

Referring to fig. 1, fig. 2 and fig. 4, the driving member 30 is mainly used for establishing a driving connection relationship between the driving member 40 and the supporting member 20, so as to drive the supporting member 20 to drive the sample container a carried by the supporting member to move correspondingly; the driving member 30 is generally constructed similar to a linear module, and the driving member 20 will be described below with reference to the carrier 20 in the sampling position.

The transmission member 30 comprises a positioning part 31 and a moving part 32 which are oppositely distributed in the front and back direction along the first direction; the positioning portion 31 extends vertically along the second direction, and the lower end portion of the positioning portion 31 can be rotatably installed on the supporting member 30 through auxiliary accessories such as a shaft rod, a bearing and the like distributed along the first direction, so that the rotation axis of the positioning portion 31 or the entire transmission member 30 is distributed along the first direction or the front-back direction, and the power end of the driving member 40 is coupled to the positioning portion 31, so as to drive the positioning portion 31 to rotate around the first direction or the rotation axis thereof within a preset angle range, and in terms of the structural distribution of the transmission member 30 on the entire transmission mechanism, the positioning portion 31 can also be understood as being rotationally swung along the left-right direction within the preset angle range; and the predetermined angular range may be set according to the moving stroke of the carrier 20, such as 45-90 °. Meanwhile, one of the positioning portion 31 and the moving portion 32 is provided with a protruding structure (which may be understood as a guiding sliding rail), and the other is provided with a groove structure (which may be understood as a guiding sliding groove) for the protruding structure to be aligned and embedded, so that the moving portion 32 can be installed on the positioning portion 31 in a manner of being linearly movable relative to the positioning portion 31 under the matching of the protruding structure and the groove structure, thereby combining and forming the transmission member 30; the supporting member 20 (specifically, the connecting portion 22) can be fixed to the moving portion 32 by means of locking, clipping, etc.

In another embodiment, the transmission member 30 may be constructed in other structures, such as a linear bearing or other mechanical components capable of realizing linear motion transmission.

Based on this, when the driving member 40 drives the positioning portion 31 to perform reciprocating rotational swing within the preset angle range, the moving portion 32 and the carrier 20 (or the sample container a) are synchronously driven to perform synchronous swing around the rotation axis of the positioning portion 31; meanwhile, under the constraint of the first guiding portion a, the second guiding portion b is enabled to move along a preset arc path, so that a pushing and pulling acting force is generated on the bearing piece 20 and the moving portion 32, and under the structural cooperation of the moving portion 32 and the positioning portion 31, the moving portion 32 and the bearing piece 20 (or the sample container a) are enabled to do linear reciprocating motion, so that the combination of rotary swing motion and linear moving motion is realized.

In particular implementations, the sample transport mechanism may generally follow a mechanism to effect movement of the carrier 20 between the sampling position and the loft position; the method specifically comprises the following steps: referring to fig. 3 and 4, when the carrier 20 is at the sampling position, the second guiding portion b (specifically, the guiding wheel) is located at the lowest portion of the first guiding portion a away from the transmission member 30; when the driving member 40 drives the carrier 40 to rotate through the transmission member 30, the second guiding portion b gradually moves along a preset arc track toward the upper portion of the first guiding portion a adjacent to the transmission member 30, so that while the carrier 20 rotates, the moving portion 32 can cause the carrier 20 to linearly extend along the length direction of the positioning portion 31, so as to finally enable the carrier 20 to reach the lofting position, at which time an operator can place the sample container a containing the sample to be tested on the carrier 20 or take the sample container a out of the carrier 20. Conversely, the carrier 20 may be rotated and linearly retracted along the length direction of the positioning portion 31 in the opposite direction, so that the carrier 20 finally reaches the sampling position.

In summary, in the first aspect, under the cooperation of the transmission member 30, the first guide portion a and the second guide portion b, the combination of the rotary swing motion and the linear movement motion of the bearing member 20 is achieved, so that the movement stroke of the bearing member 20 can be effectively increased, and the bearing member 20 can move to the outside of the accommodating space in a limited structural space; secondly, the driving effect of the composite motion of the bearing part 20 is realized by using the single driving part 40, the number of driving elements can be effectively reduced, the structure of the conveying mechanism can be simplified, and favorable conditions are created for enhancing the structural compactness of the conveying mechanism and even the whole diagnostic device, reducing the control difficulty and the like; thirdly, the problems of large device size caused by the adoption of a single linear driving structure can be avoided when the sample container A is taken out of the warehouse or put into the warehouse of the existing similar device, and the problems of insufficient movement stroke, complex structure, complex control and the like caused by the adoption of a swing driving structure when the sample container A is taken out of the warehouse or put into the warehouse of the existing similar device can be avoided.

In one embodiment, referring to fig. 3 and 4, the guide surface of the first guide portion a includes a guide section a1 and a position-limiting section a 2; wherein, the guide section a1 is arranged along a preset arc path, namely: one end of the guide section a1 is disposed adjacent to the rotation axis of the transmission member 30, and the other end is disposed away from the rotation axis of the transmission member 30, and the axial line of the guide section a1 and the rotation axis of the transmission member 20 are on the same side of the guide wheel a1, so that during the rotation and swing of the carrier member 20 driven by the transmission member 30, the second guide portion a (specifically, the guide wheel) can abut against and contact the guide section a1, so as to move along a preset arc path, thereby changing the movement track of the carrier member 20, so that the carrier member can swing and stretch; the spacing section a2 is disposed at one end of the guiding section a1 away from the rotation axis of the driving member 20, and is connected with the guiding section a1 in a smooth transition manner, and the spacing section a2 is arranged to extend up and down along the second direction, so that when the supporting member 30 stays at the sampling position, under the influence of the gravity of the supporting member 30 (with the sample container a supported by the supporting member), the moving portion 32 is caused to move down relative to the positioning portion 31, and at this time, the second guiding portion b can be moved to the spacing section a2, so that by utilizing the structural feature that the spacing section a2 extends up and down, the second guiding portion b can be restrained, so that the supporting member 20 or with the sample container a is kept at the sampling position (i.e. in an upright state).

In another embodiment, the first guiding portion a may also adopt other structural forms; for example, a cam structure is installed on the supporting member 10, and a partial outer peripheral surface of the cam structure is arranged to be distributed along a preset arc path, so as to construct a functional surface similar to the guide surface on the cam structure; as another example, a baffle structure may be provided on a side of the support member 10 facing the second guide portion b, and a side surface (such as a lower surface) of the baffle may be provided as a guide surface distributed along a predetermined arc path. Of course, the first guide portion a and the second guide portion b may also adopt other structural forms, such as a link mechanism, and the main points are that: the support can be provided for the composite motion of the carrier 20 by the cooperation of the two. All of these are not described in detail.

In one embodiment, referring to fig. 1 and 2, the sample transfer mechanism further includes a total of 2 first sensing members 50 (of course, the number of the first sensing members 50 may be 3 or more according to actual requirements), and two first sensing members 50 are distributed at intervals around the rotation axis of the positioning portion 31 on the end side periphery of the positioning portion 31 and are mounted on the support member 10; suitably, a trigger 33 capable of triggering the first sensing element 50 to operate may be disposed on the positioning portion 31; the arrangement positions of the two first sensing members 50 are associated with the sampling position and the lofting position of the carrier 20, and the driving member 40 is in communication connection with the first sensing members 50 (for example, a signal association mechanism is established between the two through a control system or the like), so that the driving member 40 can drive the positioning portion 31 to rotate and stay at a preset position within a preset angle range according to the sensing information of the first sensing members 50, thereby providing support for the carrier 20 to move between the sampling position and the lofting position; for example, when the carrier 20 moves to the sampling position, the triggering element 33 moves to one of the first sensing elements 50, so as to trigger the first sensing element 50 to output sensing information (such as an on signal or an off signal), and the driving element 40 can be activated or stopped according to the sensing information of the first sensing element 50, so that the carrier 20 stays at the sampling position or moves from the sampling position to the lofting position; conversely, the other first sensing member 50 can be triggered by the triggering member 33 so as to stop the carrier 20 at the loft position or move from the loft position toward the sampling position.

In specific implementation, the type of the first sensing element 50 may be selected according to actual conditions, for example, an optical coupler sensor is adopted, and when the triggering element 33 moves to the position of the optical coupler sensor, the optical path of the optical coupler sensor may be blocked, so that the optical coupler sensor generates a corresponding sensing signal; the first sensing member 50 may also be a piezoelectric sensor, which is pressed when the triggering member 33 moves to the position of the piezoelectric sensor, so as to trigger the piezoelectric sensor to generate a corresponding signal; all of these are not described in detail.

In one embodiment, referring to fig. 2 and 5, the sample transfer mechanism further includes a buffer 60, which is mainly used for buffering when the carrier 20 contacts with the adjacent positioning portion 31 and/or the support 10, so as to prevent the components from being damaged due to hard contact collision between the related components; referring to fig. 1, the cushion member 60 may be a pad-shaped structure made of a flexible material such as rubber, or may be an elastic pin, and the cushion member 60 is installed on the top end of the positioning portion 31 and disposed facing the supporting member 20, when the supporting member 20 moves from the lofting position to the sampling position and is in an upright state, due to the influence of gravity or inertia factors and the linear movement relationship between the moving portion 32 and the positioning portion 31, the supporting member 20 may move downward by a distance in the second direction, and at this time, the positioning portion 31 may contact the supporting member 20 through the cushion member 60, so as to prevent the supporting member 20 from colliding with the positioning portion 31. In other embodiments, the buffering member 60 may also be mounted on the supporting member 20 and located at a position where the supporting member 20 is in moving contact with the supporting member 10 or the transmission member 30.

In one embodiment, referring to fig. 1 to 4, the driving member 40 includes a power source 41 and a transmission assembly, the transmission assembly is mainly used for changing the power form, the torque, the direction, and the like of the power source 41, so that the power output by the power source 41 can stably drive the transmission member 30 to move together with the carrier 20; the power source 41 is a driving motor, and the transmission assembly comprises a first synchronous pulley 42, a second synchronous pulley 43 and a synchronous belt 44; the body of the power source 41 is fixedly arranged on the support member 10, the first synchronous pulley 42 is coaxially arranged at the power end of the power source 41 to serve as the power input end of the transmission assembly, the second synchronous pulley 43 is coaxially fixed with the positioning portion 31 to serve as the power output end of the transmission assembly, and the synchronous belt 44 connects the first synchronous pulley 42 and the second synchronous pulley 43 into a whole, so that the driving motor can drive the positioning portion 31 to rotate relative to the support member 10 sequentially through the first synchronous pulley 42, the synchronous belt 44 and the second synchronous pulley 43; the transmission assembly adopts a synchronous belt transmission structure, which not only creates favorable conditions for simplifying the structure of the driving part 40 and even the whole transmission mechanism, but also can realize the stable driving control of the transmission part 30.

In other embodiments, the power source 41 may also adopt other power devices, such as a linear power output device, such as an air cylinder, a hydraulic cylinder, an electric cylinder, and the like, and the transmission assembly may also adopt a gear transmission structure, a rack transmission structure, a link mechanism, a screw rod mechanism, and the like, and the power source 41 and the transmission assembly are combined in a matching manner, so as to realize driving control of the transmission member 30 and ensure precision and stability of the motion of the transmission member 30.

In one embodiment, referring to fig. 2, the supporting member 10 includes a first supporting portion 11 and a second supporting portion 12 arranged in parallel and at an interval along a first direction, and a third supporting portion 13 extending along a second direction, the first supporting portion 11 and the second supporting portion 12 are fixedly disposed at an end side of the third supporting portion 13, so that a projection shape of the supporting frame 10 on a vertical plane substantially presents an "L" shaped configuration; by using the first support part 11 and the second support part 12 and the structural gap therebetween, a structural space can be provided for the structural arrangement and movement of the carrier 20, the transmission member 30 and the driving member 40, if the driving member 40 is arranged on the side of the first support part 11 away from the second support part 12, the transmission member 30 is arranged between the first support part 11 and the second support part 12, and the positioning part 31 is rotatably connected to the first support part 11; the first guide portion a is disposed on the second support portion 12; with the third support portion 13, it is possible to provide a positioning for example for a sampling mechanism, so that the sampling mechanism can be brought in opposition to the sample container a in the second direction when the carrier 20 is moved to rest in the sampling position, in order to complete the sampling operation. Therefore, the assembly positions and the movement paths of other components can be reasonably distributed based on the structural configuration of the support 10, so that the whole structure of the conveying mechanism is more compact.

In one embodiment, referring to fig. 1 and 2, the supporting member 30 further includes a storage portion 23 arranged in parallel with the supporting portion 21 and selectively installed on the upper end side of the supporting portion 21 or the coupling portion 22 as required; the storage part 23 is provided with a storage bin 23a, auxiliary tools such as an adapter B of a sample container a can be stored in the storage bin 23a, the storage bin 23a can adopt a cavity structure matched with the outer contour characteristics of the adapter B, the storage bin 23a can be in a plurality, and the storage bins 13a can be arranged on the storage part 23 at intervals according to a regular sequence (such as a rectangular array), so that unified management and storage of a plurality of auxiliary tools of the same or different types can be realized, and an operator can conveniently take and place corresponding tools according to needs. Generally, an emergency treatment chamber 21a is provided on the carrier 21, and the emergency treatment chamber 21a is mainly used for positioning and fixing a sample container a containing a sample to be tested on the carrier 21, so that the carrier 20 can smoothly transfer the sample container a; since the sample containers a used vary in size and the like according to differences in the items to be tested and the like, the sample containers a are generally placed on the adapter B or the like so that the emergency room 21a can accommodate sample containers a of different sizes in cooperation with the adapter B.

When the sample conveying mechanism is applied specifically, when the bearing part 20 is driven to swing and extend the bearing part 21 from the accommodating space and stay at the lofting position, the storage part 23 moves to the lofting position synchronously along with the bearing part 21; at this time, an operator can select an adapter B adapted to the sample container a from the storage part 23 according to the specification and size of the sample container a containing the sample to be tested, after the adapter B is installed on the sample container a, the sample container a can be placed in the emergency treatment bin 23a, and the sample container a is positioned and fixed on the bearing part 21 by using the structural matching relationship between the emergency treatment bin 23a and the adapter B; the sampling operation may then be performed by the sampling mechanism as the carrier 20 moves the sample container a to the sampling location.

In one embodiment, referring to fig. 1 to 4, the sample transfer mechanism further includes a second sensing element 70, which can adopt a reflective photoelectric sensor, a piezoelectric sensor, etc. according to actual situations, and is mainly used for sensing whether the sample container a (or the adapter B) is accommodated in the emergency cabin 21a, so as to provide information support for the driving element 40, the sampling mechanism, etc. to execute corresponding functional actions; the second sensing member 70 is mounted on the carrying portion 21 (e.g. a portion near the emergency cabin 21 a) or on the supporting member 10 (e.g. the third supporting portion 13 of the aforementioned embodiment), and the driving member 40 (or together with the sampling mechanism) is in communication with the second sensing member 70 (e.g. a signal correlation mechanism is established between the two by a control system). Taking the second sensing member 70 installed on the supporting member 10 and communicatively connected to the sampling mechanism, when the supporting member 20 (specifically, the supporting portion 21) stays at the sampling position, the second sensing member 70 can be used to sense whether the sample container a or the sample container a equipped with the adapter B exists in the emergency cabin 21a, and if so, the sampling mechanism can perform the sampling operation according to the sensing information of the second sensing member 70; taking the second sensing member 70 installed on the carrying portion 21 and communicatively connected to the driving member 40 as an example, when the carrying member 20 (specifically, the carrying portion 21) stays at the lofting position, if the second sensing member 70 senses that the sample container a or the sample container a equipped with the adapter B has been placed in the emergency cabin 21a, the driving member 40 can drive the carrying member 20 to drive the sample container a to move from the lofting position to the sampling position according to the sensing signal. Accordingly, the presence of the second sensing member 70 can effectively prevent the transmission mechanism and thus the entire device from being erroneously started or idling.
