Description

Technical Field

[0001] The invention relates to the technical field of in vitro diagnostic testing instruments, in particular to a reaction cup continuous feeding device. Background Art

[0002] In the traditional technology in the field of chemiluminescence automation instruments, the reaction cup supply device has a complex structure, which is usually a cup-pushing mechanism, which lifts the reaction cup from the silo to the top and then drops it into the corresponding slide for transportation. In order to have a larger storage volume, the depth of the silo is deeper, and in order to make the reaction cups in the silo be pushed out as much as possible, the stroke of the cup-pushing mechanism should be from the bottom to the top of the silo, resulting in a larger space occupied by the cup-pushing mechanism and a larger volume, which is not conducive to the miniaturization of the overall structure. The large stroke also leads to a slower cup discharge speed; the cup-pushing mechanism is prone to cup jamming during the up and down movement, resulting in a higher rate of residual cups in the silo.

The beneficial effects of the present invention are as follows: The present invention provides a reaction cup continuous feeding device. Compared with the prior art, the present invention has at least the following technical effects: 1. By changing the way of discharging cups from the top of the magazine to setting a discharge port at the bottom of the magazine for discharging from the bottom, the reaction cups will automatically concentrate towards the discharge port at the bottom under the action of their own gravity, which can avoid the problem of high cup retention rate. And the control of discharging is set as a circulating swing discharging outside the magazine, and its stroke is smaller than that of the lifting and abutting discharging method, and the occupied space is smaller, which is beneficial to the miniaturization of the structure and the improvement of the cup discharging efficiency; and it does not occupy the space inside the magazine, and can increase the storage volume of the magazine. 2. The control of discharging adopts a driving member and a connecting rod group to drive the upper swing plate and the lower swing plate to swing back and forth to realize the switching of the discharging channel between the material receiving state and the discharging state. The swinging method makes the switching stroke shorter and the speed faster, which can improve the feeding efficiency of the reaction cups. Its structure is more compact and the occupied space is small, which can save costs. 3. By driving the back-and-forth swing through the connecting rod method, the driving member only needs to rotate to realize the back-and-forth swing of the upper swing plate or the lower swing plate. The control method is simple, which helps to reduce the failure rate and further improve the production efficiency. 4. An ear plate clamp block is provided with a deceleration block at the outlet of the discharging channel. Since the discharging channel is relatively smooth, the falling speed of the reaction cup is very fast at this time, and phenomena such as flipping and lying flat are likely to occur. The setting of the deceleration block blocks a part of the cup edge of the reaction cup to provide deceleration for the reaction cup to avoid flipping and lying flat phenomena. 5. The setting of the first chute is convenient for guiding the discharged reaction cups into the transfer mechanism. A first full cup photoelectric coupler is provided in the first chute. When the cups stacked on the chute reach the specified position, the first full cup photoelectric coupler will be triggered by induction, and at this time, the driving member stops rotating to prevent excessive stacking of reaction cups. 6. The guiding and pushing assembly includes a guiding seat, and a guiding rotating shaft provided with a guiding groove is arranged in the guiding seat. The setting of the guiding groove allows one reaction cup to enter each time, provides pauses and turns for the supply of reaction cups, and sequentially sends the reaction cups into the cup supply mechanism one by one. 7. The setting of the cup rotating baffle can make the continuously incoming reaction cups rotate clockwise around its axis driven by the guiding rotating shaft and be blocked by the cup rotating baffle fixed in the guiding seat. Then, they will be squeezed by the subsequently transported reaction cups, pushed out of the guiding groove outlet and pushed into the second chute to realize the individual discharging of reaction cups. 8. A cup supply rotating shaft is rotatably arranged in the cup supply base, and a plurality of cups to be taken slots are arrayed on the circumferential surface of the cup supply rotating shaft. The cooperation between the cup supply base and the cups to be taken slots on the cup supply rotating shaft sequentially transports the reaction cups to the specified positions for the external equipment to accurately grab.

The control of discharging is realized by driving the upper swing plate and the lower swing plate to swing back and forth by the drive member and the link group, so as to switch the discharge channel back and forth between the material receiving and discharging states.

The ear plate clamping block 17 is provided with a deceleration blocking block at the outlet of the discharge channel. Since the discharge channel is relatively smooth, the falling speed of the reaction cup 23 is very fast at this time, and phenomena such as flipping and lying flat are likely to occur.

[0037] Please refer to Figure 1 , Figures 8 to 10 , preferably, the guiding and pushing component includes a guiding seat 28 and a guiding rotating shaft 29 rotatably installed in the guiding seat 28.

The guiding and pushing component includes a guiding seat 28. A guiding rotating shaft 29 provided with guiding grooves is arranged in the guiding seat 28. The setting of the guiding grooves allows one reaction cup 23 to enter at a time, provides pauses and turns for the supply of the reaction cups 23, and sends the reaction cups 23 into the cup supply mechanism one by one. Preferably, the pushing driving part 25 is a transfer motor.

[0038] Please refer to Figure 1 , Figures 8 to 10 , preferably, a cup rotating baffle 30 is further installed in the guiding seat 28. The cup rotating baffle 30 is arranged at the guiding groove outlet and extends into the rotation path of the guiding groove, and is located on the side where the guiding groove sweeps away from the guiding groove outlet, and is used to push the reaction cup 23 out of the guiding groove to the guiding groove outlet. The setting of the cup rotating baffle 30 can block the continuously moving reaction cups 23 driven by the guiding rotating shaft 29 to rotate clockwise around its axis. The cup rotating baffle 30 fixed in the guiding seat 28 will be blocked, and then will be squeezed by the subsequently transported reaction cups 23, pushed out to the guiding groove outlet and then pushed into the second slideway, realizing the individual discharging of the reaction cups 23.

[0039] See also Figure 1 , Figures 11 to 13 Preferably, a cup supply shaft 41 is rotatably provided in the cup supply base 36, and a plurality of slots to be taken are arranged in an array on the circumference of the cup supply shaft 41. A seat entrance to be taken is provided on the side wall of the cup supply base 36, and the slots to be taken can be connected with the seat entrance to be taken in sequence. The cup supply shaft 41 is driven to rotate by the cup supply motor 35, and a second slide is connected between the seat entrance to be taken and the guide groove outlet. A cup supply shaft 41 is rotatably provided in the cup supply base 36, and a plurality of slots to be taken are arranged in an array on the circumference of the cup supply shaft 41.

[0040] See also Figure 1 , Figures 11 to 13 Preferably, the cup supply base 36 is fixed on the cup supply base body 37, and the cup supply motor 35 is fixed on the lower end of the cup supply base body 37.

After the reaction cup 23 enters the waiting slot, as the cup supply shaft 41 rotates through the sensing area of the reaction cup in-position optical coupling 39, it means that the next reaction cup 23 can be grabbed. At this time, the cup supply shaft 41 rotates again to reach the grabbing point, and the grabbing device in the external device grabs the reaction cup 23. The cup supply transfer optical coupling shield 40 and the cup supply transfer optical coupling 38 are used to determine the rotation angle of the cup supply shaft 41, that is, the position of the guide slot, so as to accurately deliver the reaction cup 23 to the cup supply position.

[0041] The working principle of the present invention is as follows: The swing driving member 2 drives the first connecting rod 11, driving the first connecting rod 11 and the second connecting rod 12 to rotate. Due to the fixation of the feeding left support block 4, the feeding right support block 19 and the feeding fixing frame 20, the lower ear plate 13 dragged by the connecting rod will rotate within a certain angle. The ear plate clamping block 17 is restricted by the upper swing plate left limit 16 and the upper swing plate right limit 18 and cannot move left and right.

[0042] At the same time, due to the restriction of the long connecting rod 14 and the fixation of the ear plate clamping block 17, it is determined that the lower ear plate 13 and the upper ear plate 15 are parallel to each other, and a discharge channel for the reaction cup 23 to pass through is formed. The height of the discharge channel changes with the angle, as shown in Figure 6 , Figure 7 .

[0043] When the length formed by the first connecting rod 11 and the second connecting rod 12 is the longest, the reaction cup 23 falls from the inlet of the discharge channel. Since the slideway is relatively smooth, the falling speed of the reaction cup 23 is very fast at this time, and phenomena such as flipping and lying flat are likely to occur. Therefore, a deceleration baffle 24 is provided. As the first connecting rod 11 rotates, the deceleration baffle 24 will be raised and just block a part of the cup edge of the reaction cup 23 to provide deceleration for the reaction cup 23 (see Figure 6 ); when the first connecting rod 11 continues to rotate to the position where the length formed by the first connecting rod 11 and the second connecting rod 12 is the shortest, the reaction cup 23 has entered the first slideway. At this time, a new cup will enter the inlet of the discharge channel (see Figure 7 ), and as the first connecting rod 11 rotates and rises to the Figure 6 position, the just-entered reaction cup 23 enters the first slideway and repeats the above actions. That is, the feeding mechanism drives the first connecting rod 11 and the second connecting rod 12 through the motor (swing driving member 2), and continuously sends the reaction cup 23 from the discharge channel to the first slideway (the first slideway is composed of the first left slideway 21 and the first right slideway 22, and the distance between the two is a certain width, and the cup edge of the reaction cup 23 can hang on the first slideway. A first full cup optical coupler is provided on the slideway. When the cups stacked on the first slideway reach the specified position, the first full cup optical coupler will be triggered by induction, and at this time, the swing driving member 2 stops rotating to prevent the reaction cup 23 from accumulating excessively.).

[0044] After that, the reaction cup 23 slides down from the first slideway and enters the guiding groove of the guiding seat 28 through the guiding groove entrance of the guiding seat 28. At this time, in the guiding groove opposite to the guiding groove entrance, the function of the transfer mechanism is to provide pauses and turns for the supply of the reaction cup 23. The guiding rotating shaft 29 is driven by the transfer motor to rotate, and the reaction cups 23 are sent into the second slideway one by one. Specifically, the continuous reaction cups 23 rotate clockwise in the guiding seat 28 driven by the guiding rotating shaft 29 and are blocked by the rotating cup baffle 30 fixed on the base body of the transfer mechanism. Then, they are pushed into the second slideway by the subsequent transferred reaction cups 23 and then enter the cup supply base 36 along the second slideway (when the reaction cups 23 on the second slideway accumulate to the induction area, the transfer mechanism will stop working and no longer transport the reaction cups 23).

[0045] The function of the cup supply base 36 is to transfer the reaction cup 23 to the designated position and wait to be grabbed by the grasping component in the external device. The reaction cup 23 in the second slideway enters the cup supply rotating shaft 41 through the entrance of the waiting-to-be-grabbed seat and into the waiting-to-be-grabbed groove opposite at this time. Then, the cup supply motor 35 works to drive the cup supply rotating shaft 41 to start rotating clockwise by 60°. When the reaction cup in-place optocoupler 39 senses the reaction cup 23 in the induction area, it means that the next reaction cup 23 can be grabbed. At this time, the cup supply rotating shaft 41 rotates another 120° to reach the grasping position, and the grasping device in the external device can grab the reaction cup 23.
