The second driving portion 22 is formed by disposing the driving member 222 and the fitting member 221 separately. If the pushing portion 23 is directly driven by the driving mechanism, the driving mechanism under high speed operation cannot be stopped immediately after receiving a start or stop command, which easily causes the pushing portion 23 to move too much or stop when it does not reach a set position. Therefore, by arranging the driving component 222 and the matching component 221 which are matched, the matching component 221 is used as a buffer, so that the positioning precision of the pushing part 23 can be controlled more accurately and stably, and the problem that the positioning precision of the driving mechanism is not high is solved.

The accommodating position 61 is directly set in a groove structure formed by opening at the edge of the dispensing disc 6, so that the reaction container 5 can be directly extruded into the groove from the cup inlet 112 of the cup inlet station 1a in the rotating process of the dispensing disc 6, and the reaction container 5 is connected to the dispensing disc 6 through the matching of the container shoulder 52 and the dispensing disc 6, the structure is simple, and the cup inlet efficiency is improved.

The second driving part 22 is connected to the mounting bracket 21, the pushing part 23 is connected to the second driving part 22, and the second driving part 22 is used for driving the pushing part 23 to move, so that the matching component 221 can drive the pushing part 23 to separate the reaction vessel 5 from the dispensing disk 6 and move to a preset position along the first channel 213. Taking one of the reaction containers 5 as an example, when the dispensing disk 6 rotates to the cup discarding station 1d after driving the dispensing disk through the cup entering station 1a, the sample adding and mixing station 1b, and the detecting station 1c, the opening 611 of the accommodating station 61 provided with the reaction container 5 is opposite to the cup outlet 113, so that the extending directions of the reaction container 5 and the first channel 213 are in a straight line, and as long as the pushing part 23 abuts against at least part of the reaction container 5 and applies a force in a direction away from the axis of the body 1, the reaction container 5 can be smoothly taken out from the position of the opening 611 of the dispensing disk 6 along the radial direction of the body 1 and directly enters the first channel 213 along with the pushing of the pushing part 23. The matching structure is simple, the reaction container 5 is convenient to push, and the work of abandoning the reaction container 5 from the first channel 213 to the collecting device can be well completed.

In one embodiment, the matching assembly 221 includes a guiding rail 221a and a sliding block 221b, the guiding rail 221a extends along the radial direction of the body 1, the pushing portion 23 is connected to the sliding block 221b, and the sliding block 221b can move along the guiding rail 221a to drive the pushing portion 23 to move along the extending direction of the first channel 213. By arranging the guide rail 221a and the sliding block 221b which are matched with each other, the power provided by the driving assembly 222 is converted into the sliding of the sliding block 221b relative to the guide rail 221a, so that the movement precision of the sliding block 221b relative to the guide rail 221a can be better controlled, the displacement precision of the pushing part 23 can be further improved, the pushing part 23 can be favorable for accurately separating the reaction container 5 from the dispensing disc 6 and pushing the reaction container 5 to the first channel 213, the abandoning work of the reaction container 5 can be smoothly realized, and the reaction container 5 is prevented from being accumulated in the first channel 213.

The driving assembly 222 includes a driving motor 222a and a synchronous pulley set, the synchronous pulley set includes a first synchronous pulley 222b, a second synchronous pulley 222c and a second synchronous belt connecting the two, the first synchronous pulley 222b is connected to the output shaft of the driving motor 222a, the second synchronous pulley 222c is connected to the mounting bracket 211, the sliding block 221b is connected to the second synchronous belt, the plane formed by the connecting line between the axis of the first synchronous pulley 222b and the axis of the second synchronous pulley 222c is parallel to the extending direction of the guide rail 221a, and the driving motor 222a can drive the first synchronous pulley 222b to rotate, so that the second synchronous belt is matched to drive the sliding block 221b to slide along the guide rail 221 a. Through the synchronous belt group connected with the output shaft of the driving motor 222a, the rotation of the driving motor 222a is converted into the motion of the synchronous belt, the motion speed of the synchronous belt is far lower than the rotation speed of the driving motor 222a, and compared with the situation that the motion of the sliding block 221b is controlled by directly controlling the driving motor 222a to start or stop rotating, the motion precision of the sliding block 221b is controlled to be higher by controlling the motion of the synchronous belt, so that the higher motion precision of the pushing part 23 is ensured, and the situations of under-motion or over-motion and the like of the pushing part 23 are avoided.

Optionally, the second driving portion 22 further includes a limiting component, the limiting component is used for limiting the movement of the sliding block 221b, the limiting component includes a stroke block 221c and a stroke controller, the stroke block 221c is connected to the sliding block 221b, and the stroke controller is respectively located at two sides of the stroke block 221c along the extending direction of the guide rail 221 a. When the sliding block 221c moves along the guide rail 221a, through the matching of the set stroke control and the stroke block 221c, the sliding block 221b can be prevented from driving the pushing part 23 to move excessively when the driving component 222 fails, the movement of the pushing part 23 is limited to a limited range to reciprocate, and the stability and the precision of the movement of the pushing part 23 are improved. The set stroke control may be a butting block for limiting the movement of the sliding block 221c by butting the stroke block 221c and the butting block, or may be a photosensitive automatic control structure such as an optical coupler for limiting the sliding block 221 c. Or other stroke control capable of realizing limit may also be set, and is not limited specifically herein.

Specifically, the mounting bracket 21 includes a mounting seat 212 and a mounting plate 211 disposed thereon, the mounting seat 212 is connected to one side of the body 1, the mounting plate 211 extends along a radial direction of the body 1 and partially protrudes out of the mounting seat 212 to above the body 1, the second driving portion 22 is disposed on the mounting plate 211, the first channel 213 is disposed on the mounting seat 212, the mounting plate 211 is provided with a moving channel 211a, the moving channel 211a is communicated with the first channel 213, and the pushing portion 23 at least partially penetrates through the moving channel 211 a. By arranging the mounting plate 211 and the mounting seat 212 which are matched with each other, the second driving part 22 can drive the pushing part 23 to push the reaction vessel 5 out of the dispensing disc 6 in the reciprocating motion process, drive the pushed reaction vessel 5 to enter the first channel 213 and push the reaction vessel 5 to a fixed collecting position along the first channel 213 to complete the cup abandoning work, and avoid the reaction vessel 5 from being accumulated in the first channel 213 or not being separated from the dispensing disc 6.

It is understood that the fitting plate 211 and the fitting seat 212 are engaged with each other in order to achieve good engagement between the second driving unit 22, the pushing unit 23, the dispensing disk 6, the reaction vessels 5 thereon, and the first channel 213, and to stably push the reaction vessels 5 to the collection position without accumulating in the first channel 213. Therefore, for the cup disposal mechanism 2, the specific structural cooperation between the parts can be, for example: the mounting seat 212 is arranged at the side part of the body 1 corresponding to the cup discarding station 1d, one side of the mounting seat 212 facing the body 1 is provided with a first channel 213 extending along the radial direction of the body 1, the first channel 213 extends into the accommodating cavity 111 through the cup outlet 113 to be in clearance fit with the internal injection disk 6, and when the reaction vessel 5 rotates to the cup discarding station 1d along with the injection disk 61, the opening 611 of the accommodating position 61 provided with the reaction vessel 5 is opposite to the first channel 213. The portion of the mounting plate 211 above the mounting seat 212 extends at least above the dispensing disc 6 corresponding to the reaction vessel 5 along the radial direction of the body 1, so that when the slide block 221c drives the pushing portion 23 to move, the pushing portion 23 can move at least above the receiving position 61, and push the reaction vessel 5 to be ejected and enter the first channel 213 after the pushing portion 23 abuts against the side of the reaction vessel 5 away from the opening 611. The pushing portion 23 is disposed above the reaction container 5, so that the stability and strength of the force applied to the reaction container 5 can be improved, and the extending length of the corresponding guide rail 221a, the specific positions of the limiting component relatively disposed on the two sides of the sliding block 221c, the specific arrangement positions of the two synchronous pulleys in the driving component 222, the extending length and position of the moving channel 211a along the radial direction of the body 1, and the like can be adaptively adjusted according to the setting of the pushing portion 23, which is not specifically limited herein.

When the reaction container 5 is rotated to be located at the cup discarding position 1d, since the reaction container 5 is a cup body structure having the container shoulder 52 therein, in order to enable the pushing portion 23 to have a good cup pushing effect on the reaction container 5, the reaction container 5 can be rapidly and stably released from the opening 611 to the first channel 213 along the radial direction of the body 1. The pushing portion 23 includes a dial 232 and a base 231 connecting the dial 232 to the sliding block 221b, the dial 232 passes through the moving channel 211a, the dial 232 has an abutment surface 232a, and the abutment surface 232a is used for abutting against the sidewall of the container shoulder 52 to push the reaction container 5 to move. Before the reaction container 5 reaches the cup discarding station 1d, the shifting block 232 can move to a position above the cup discarding station 1d corresponding to the accommodating position 61 in advance, and at least part of the shifting block 232 is located on one side of the accommodating position 61 far away from the second driving part 22, so that when the reaction container 5 reaches the cup discarding station 1d, one side of the reaction container 5 far away from the opening 611 can be abutted against the abutting surface 232a, and the reaction container 5 can be driven to be separated from the dispensing disc 6 by the movement of the shifting block 232 towards the side close to the opening 611.

Optionally, when the shifting block 232 is engaged with the reaction vessel 5 having the vessel shoulder 52 to push the reaction vessel to be disengaged from the dispensing disc 61, a surface of the shifting block 232 facing a side of the first channel 213 is provided with a recess 232b, so that the shifting block 232 forms two opposite convex structures along a radial direction of the body 1, and the abutting surface 232a is provided on at least one opposite side wall of the convex structure. When the cup discarding mechanism 2 is operated, at least a part of the container shoulder 52 of the reaction container 5 is located in the recess 232b, and the abutment surface 232a corresponds to the reaction container 5 in the radial direction of the body 1. When the drive paddle 232 moves to separate the reaction vessel 5 from the dispensing tray 6, at least the abutment surface 232a on the side away from the opening 611 abuts the reaction vessel 5 and pushes the reaction vessel 5 to move in the radial direction to enter the first path 213.

With the paddle 232 provided, the surface thereof on the side facing the first channel 213 may be flush with or clearance-fitted to the lower surface of the cell shoulder 52 when the reaction cell 5 is placed on the dispensing disk 6. When the two are in clearance fit, the surface of the side of the dial 232 facing the first channel 213 is above the lower surface of the container shoulder 52 as seen in the height direction of the incubation unit, and the clearance between the two surfaces is no more than half the height of the container shoulder 52.

In an alternative embodiment, the pushing portion 23 may also be configured as two clamping blocks capable of approaching or separating from each other along the radial direction of the body 1, the movement of the two clamping blocks approaching or separating from each other may be controlled by the driving member, before the reaction vessel 5 enters the cup discarding station 1d, the pushing portion 23 is located above the dispensing disc 6, and the two clamping blocks are respectively located at two sides of the reaction vessel 5 to be entered, until the reaction vessel 5 enters the cup discarding station 1d, the two clamping blocks may be controlled to clamp the reaction vessel 5, and then the reaction vessel 5 may be conveniently and rapidly separated from the dispensing disc 61 into the first channel 213 by the control of the second driving portion 222, the structural matching stability of the pushing portion 23 is good, and the reaction vessel 5 may be accurately put into the collecting position from the first channel 213. Other configurations of the pushing portion 23 may be provided to ensure that the reaction vessels 5 are pushed to the collection position, so as to avoid accumulation in the channel, not to mention here.

In one embodiment, the first channel 213 includes a first sub-channel 213a and a second sub-channel 213c connected to each other along the extending direction of the first channel 213, the first sub-channel 213a is located above the second sub-channel 213c, and the width of the first sub-channel 213a is greater than the width of the second sub-channel 213c, so that a stepped surface 213b is formed therebetween, and the stepped surface 213b is flush with or clearance-fitted to the surface of the paddle 232 close to the first channel 213 along the height direction of the incubation unit. With respect to the first sub-passage 213a and the second sub-passage 213c provided, the shape of the cross section thereof in the extending direction of the first passage 213 is the shape of the cross section of the reaction vessel 5 having the vessel shoulder 52, and the width of the second sub-passage 213c is not less than the diameter of the vessel body 51 and not more than the width of the vessel shoulder, and not more than 5mm of the diameter of the vessel body 51 at most. The width of the first sub-passage 213a is greater than the diameter of the container shoulder 52. The design of the first sub-channel 213a and the second sub-channel 213c enables the reaction vessel 5 to be limited in the channel with limited space when the pushing part 23 pushes the reaction vessel 5 into the first channel 213, and the lower surface of the vessel shoulder 52 in the reaction vessel 5 contacts with the stepped surface 213b, so that when the pushing part 23 pushes the reaction vessel 5 out into the first channel 213, the reaction vessel 5 can directly enter the first channel 213 along the radial direction, and the phenomenon of skewness caused by uneven force when pushing the reaction vessel 5 is avoided by means of shape matching, which results in the accumulation of the reaction vessel 5 in the first channel 213 and the inability of being pushed to a fixed collection position by the pushing part 23.

Optionally, the mounting seat 212 further includes a second channel 214 communicating with the first channel 213, the second channel 214 intersects the first channel 213, and the pushing part 23 can push the reaction vessel 5 from the first channel 213 into the second channel 214. With the second passage 214 provided for communicating with the collecting means for collecting the used reaction vessels 5, the diameter of the second passage 214 is at least larger than the height of the reaction vessels 5 so that the reaction vessels 5 can smoothly enter the collecting means from the second passage 214. The extending direction of the second channel 214 may be perpendicular to the extending direction of the first channel 213 or inclined downward at a certain angle with respect to the extending direction, as long as the reaction vessels 5 are not stacked or stuck in the second channel 214, and is not particularly limited.

It will be appreciated that the predetermined positions referred to above may be defined differently depending on the configuration of the first channel 213, the second channel 214, etc. disposed in the mounting seat 212. For example, when the first passage 213 and the second passage 214 intersecting as described above are provided, the preset position thereof is the intersection position where the two passages intersect. The reaction container 5 is not particularly limited as long as the reaction container 5 can be pushed to a predetermined position and the reaction container 5 can directly or indirectly enter the collecting device.

Optionally, a position detecting assembly 3 may be further included, and the position detecting assembly 3 is disposed in the cup discarding mechanism 2 and is used for detecting a position reached by the reaction container 5 during the cup pushing process and a situation whether the reaction container is in place or not, so as to avoid stacking of the reaction container 5, and a specific structure of the detecting assembly 3 and a cooperation with the cup discarding mechanism 2 are not described in detail herein.

In an optional embodiment, the device further comprises a control unit, the control unit is electrically connected with at least the second driving part 22 and the third driving part 11a, and the control unit can be arranged in combination with a time sequence to ensure that the cup discarding work of the reaction containers 5 in the cup discarding station 1d can be completed efficiently and accurately, so as to avoid the accumulation of the reaction containers 5.

It can be understood that, in the process of rotating the dispensing disc 6, an in-place detection device such as an optical coupler is arranged at a position corresponding to each station, and the control unit can complete sample analysis according to the arranged in-place detection device and the combination of components in each station according to time sequence. Taking a reaction vessel 5 as an example, when the dispensing disc 6 rotates to an empty accommodating position 61 opposite to the cup inlet 112, the in-place detection device sends a signal to the control unit, and the control unit controls the third driving unit 11a to stop the operation of driving the dispensing disc 6 to rotate, and continues to rotate after the cup inlet operation is completed. The sample mixing station 1b and the detection station 1c are sequentially passed through in time sequence according to the same principle, and a detailed description is omitted.
