Referring to fig. 2 and 4, an embodiment of the present application provides a cup adding device, which includes a chute assembly 100, a bin assembly 200, and a cup pushing assembly 300.

When the cup adding device is used, the cup pushing piece 320 pushes the reaction cup 400 in the accommodating groove 210 to the slideway 110 when moving along the first direction, and the slideway 110 conveys the reaction cup 400 to a subsequent station; while the cup pushing member 320 moves along the first direction, the blocking member 330 also moves along the first direction, and the blocking member 330 is partially accommodated in the slide way 110 during the movement process and can block the reaction cup 400 sliding on the slide way 110, and the blocked reaction cup 400 pauses sliding and is aligned in a vertical state; after the cup pushing member 320 pushes the reaction cup 400 from the receiving slot 210 into the slide 110, the cup pushing member 320 and the blocking member 330 move in a direction opposite to the first direction for the next time the cup is pushed in preparation, during which the blocking member 330 moves away from the slide 110, and the reaction cup 400 on the slide 110 continues to slide in a vertical posture and enters a subsequent station. By arranging the blocking piece 330 to be capable of righting the gesture of the reaction cup 400 sliding on the slideway 110, the reaction cup 400 can enter the subsequent station in a vertical gesture, so that the cup clamping failure rate of the cup adding device is reduced, and the cup adding efficiency is improved.

It should be noted that, the type of the sensor 810 may be determined according to actual needs, for example, an infrared correlation sensor 810 may be adopted, which is installed on the bin assembly 200 in pairs, one of which is a signal transmitting end, and the other of which forms a signal receiving end, when the signal transmission between the two ends is cut off, it may be determined that more reaction cups 400 remain in the accommodating groove 210, and when the signal transmission between the two ends is cut off, it may be determined that the residual quantity of the reaction cups 400 in the accommodating groove 210 is less, and at this time, relevant personnel may be reminded to add the reaction cups 400.

Referring to fig. 2 and 3, taking a synchronous belt transmission system as an example, the driving mechanism 310 includes a driving member 311, a driving wheel 312, a driven wheel 313 and a synchronous belt 315.

Optionally, the driving mechanism 310 further includes an axle 314, the axle 314 is disposed on the bracket 500, and the driven wheel 313 is rotatably sleeved on an outer peripheral side of the axle 314.

Alternatively, the driving member 311 may be a stepping motor.

Further, in a specific embodiment, a guide rail 600 may be further disposed on a side of the support 500 near the timing belt 315, and a slider 700 capable of sliding along the guide rail 600 may be disposed on the guide rail 600, and then the cup pushing member 320 may be fixedly connected to the slider 700, so that the shaking phenomenon of the cup pushing member 320 and the blocking member 330 during the lifting process may be minimized.

Referring to fig. 5 and fig. 6, in some embodiments, one end of the cup pushing member 320 is provided with a plurality of transition portions 322 and at least two supporting portions 321, the at least two supporting portions 321 are used for pushing the reaction cup 400 together, the transition portions 322 and the supporting portions 321 are staggered, and in the first direction, the transition portions 322 are concavely arranged on the supporting portions 321; the bin assembly 200 is provided with a limiting piece 230 and a discharging opening 221, the limiting piece 230 is arranged on one side of the discharging opening 221 facing the first direction, and the cup pushing piece 320 can push the reaction cup 400 into the slideway 110 through the space between the discharging opening 221 and the limiting piece 230.

It can be understood that the cuvette 400 having a length direction perpendicular to the first direction (i.e., the cuvette 400 in the horizontal state in fig. 5) can be supported by the at least two support portions 321 while being moved in the first direction along with the cuvette pushing member 320, and can be pushed into the slide way 110 by the at least two support portions 321; for the reaction cup 400 with an included angle between the length direction and the first direction being smaller than 90 degrees (i.e. the reaction cup 400 in the inclined state in fig. 6), one end of the reaction cup 400 is supported on the supporting portion 321, or slides off the supporting portion 321 and is supported on the transition portion 322, and the other end of the reaction cup 400 is located at the side of the discharge opening 221 facing the first direction, and the limiting member 230 can prevent the reaction cup from moving towards the slideway assembly 100 when the reaction cup follows the cup pushing member 320 to move along the first direction.

By adopting the technical scheme, the reaction cup 400 can maintain a consistent posture when entering the slideway 110 from the accommodating groove 210, so as to provide for maintaining the consistent posture when the reaction cup 400 slides in the slideway 110.

Further, in a specific embodiment, referring to fig. 7, the transition portion 322 is disposed obliquely, and in the first direction, an end of the transition portion 322 near the ramp assembly 100 is higher than an end of the transition portion 322 remote from the ramp assembly 100.

Through the above technical scheme, the included angle between the length direction and the first direction is smaller than 90 degrees, and the reaction cup 400 with one end sliding from the supporting portion 321 and supported on the transition portion 322 can smoothly slide into the accommodating groove 210 along the inclined surface of the transition portion 322.

In some embodiments, referring to fig. 7, the upper surface of the support portion 321 is a curved surface protruding toward the first direction.

By adopting the above technical scheme, for the reaction cup 400 with the included angle between the length direction and the first direction being smaller than 90 degrees, one end of the reaction cup slides from the supporting portion 321 and is supported on the transition portion 322.

In some embodiments, the upper surface of the supporting portion 321 is a curved surface inclined toward the feed opening 221.

By adopting the above technical solution, the reaction cup 400 having the length direction perpendicular to the first direction can move more smoothly into the slide way 110 when moving to the discharge opening 221 along the first direction along with the cup pushing member 320.

In a specific embodiment, referring to fig. 7, when the cup pushing member 320 draws materials, a rectangular flat plate may be selected, two notches are formed at one end of the rectangular flat plate by removing materials, the upper surfaces of the materials at two sides of the notches are cut into curved surfaces to form the supporting portion 321, and part of the materials of the rectangular flat plate at the notches are removed to form inclined surfaces at the notches, so as to form the transition portion 322. Of course, the cup pushing member 320 may be integrally formed by casting or the like.

Further, in a specific embodiment, referring to fig. 5 and 6, in the first direction, the height of the space between the feed opening 221 and the stopper 230 is greater than the maximum width of the reaction cup 400 in the radial direction and less than the height of the reaction cup 400 in the inclined state; and in a projection to a plane perpendicular to the first direction, the cup pushing member 320 has an overlapping portion with the stopper 230.

So arranged, the reaction cup 400 in a horizontal state can smoothly pass through the first space; and in the process that the reaction cup 400 in the inclined state moves along the first direction along with the cup pushing member 320, the reaction cup 400 may strike the limiting member 230, so that the reaction cup 400 in the inclined state may drop into the receiving groove 210 from the cup pushing member 320 under the force provided by the limiting member 230.

In some embodiments, the bin assembly 200 includes a plurality of sidewall plates 220, the plurality of sidewall plates 220 are surrounded to form the receiving slot 210, the feed opening 221 is formed on one of the sidewall plates 220, and the limiting member 230 is connected to the sidewall plate 220. Referring to fig. 4, sidewall plate 220 is a sidewall of receiving groove 210. The blanking opening 221 is a notch formed on the side wall plate 220 between the cup pushing member 320 and the slideway assembly 100, and the limiting member 230 is connected to the side wall of the accommodating groove 210 and is disposed above the side wall plate 220, and cooperates with the blanking opening 221 to form a first space.

Further, in a specific embodiment, the limiting member 230 is an elastic member. By adopting the above technical scheme, when the limiting member 230 prevents the reaction cup 400 from moving towards the slideway assembly 100, the acting force of the limiting member 230 on the reaction cup 400 can be reduced, so that the damage to the reaction cup 400 is reduced.

Alternatively, the stopper 230 may be a sleeve spring, or a plate made of a material having a certain elasticity such as rubber, silicone, or the like.

In some embodiments, the bin assembly 200 further includes a partition 240 connected to a sidewall of the receiving slot 210, the partition 240 dividing the receiving slot 210 into a cup adding area and a cup pushing area with bottoms in communication with each other, and the cup pushing member 320 may push the reaction cup 400 in the cup pushing area into the slide 110.

Specifically, when adding the reaction cup 400 into the accommodating cavity, the reaction cup 400 can be added into the cup adding area, the baffle plate 240 can block and slow down the reaction cup 400 entering the cup pushing area, so that the reaction cup 400 in the cup adding area can slowly and orderly enter the cup pushing area, and less reaction cups 400 enter the cup pushing area, the collision impact between the reaction cups 400 is relieved, the damage rate of the reaction cups 400 is greatly reduced, and in addition, the cup adding area can also serve as a replenishing bin of the cup pushing area, and the reaction cups 400 are replenished to the cup pushing area along with the gradual consumption of the reaction cups 400 in the cup pushing area.

To prevent scratching of the reaction cup 400, the partition 240 may be entirely made of a material having a low hardness, alternatively, it may be made of a material having a certain elasticity such as rubber, silica gel, or the like.

In some embodiments, the partition 240 includes a partition 241 and a perspective portion 242 connected to each other, the partition 241 being provided in the receiving groove 210 for partitioning the cup adding region and the cup pushing region, and the perspective portion 242 being provided above the cup pushing region in the first direction and closing the cup pushing region.

By adopting the technical scheme, on one hand, the reaction cup 400 can be prevented from falling from the opening of the cup pushing area under the pushing of the cup pushing piece 320; on the other hand, the allowance of the reaction cup 400 in the cup pushing area is convenient to observe the movement state of the reaction cup 400 in the cup pushing process.
