Referring to fig. 1 to 3, the present invention provides a multi-layer stepped lifting plate feeding mechanism for feeding materials stored in a bin 200 into a sorting flow channel 300, wherein the bin 200 is disposed on a rack 100, and the multi-layer stepped lifting plate feeding mechanism includes:
a first step lifting assembly 400 liftably disposed in the bin 200, and including a plurality of first step plates 401 disposed in parallel; the height of each first step plate 401 gradually decreases along the direction away from the sequencing channel 300, and the top of each first step plate 401 is provided with an inclined first guide surface 401 a;
the second step lifting assembly 500 is arranged in the storage bin 200 in a lifting manner, and comprises a plurality of second step plates 501 arranged in parallel, and the second step plates 501 and the first step plates 401 are arranged in a staggered manner; the height of each second step plate 501 gradually decreases along the direction away from the sequencing channel 300, and the top of each second step plate 501 is provided with an inclined second guide surface 501 a;
the driving assembly 600 is used for driving the first step lifting assembly 400 and the second step lifting assembly 500 to do lifting movement;
through the matching motion of the first ladder lifting assembly 400 and the second ladder lifting assembly 500, the materials can be jacked up one by one and enter the sequencing runner 300.
Specifically, the material in this embodiment is a reaction cup, and the reaction cup is a container for providing a sample, adding a reagent, reacting, mixing, and detecting to an instrument. The storage bin 200 is used for storing reaction cups and realizing the uniform-speed outflow of the reaction cups, and a window is arranged on the side surface of the storage bin 200 and can be used for observing the allowance and the state of the reaction cups in the storage bin 200. The sequencing runner 300 is positioned at the discharge end of the bin 200, the reaction cup slides in from the side surface of the sequencing runner 300 after being jacked up, the reaction cup is provided with a flanging arranged along the circumferential direction of the outer edge, the flanging is clamped on the upper edges of the side walls at two sides of the sequencing runner 300, and the reaction cup is changed into a vertical state by self weight; the sequencing channel 300 is of sufficient length to accommodate a row of reaction cups simultaneously for use in subsequent modules.
By arranging the two stepped lifting assemblies, the structure of the feeding mechanism can be simplified, the manufacturing and assembling cost is reduced, and the failure rate is further reduced; the original bin bottom disturbance connecting rod mechanism is eliminated, and two stepped lifting assemblies are changed, so that the number of parts is reduced, and the assembly complexity is reduced.
Through the matching alternate lifting motion of the first ladder lifting assembly 400 and the second ladder lifting assembly 500, the materials can be jacked up one by one and enter the sequencing runner 300. And, the first step lift assembly 400 and the second step lift assembly 500 perform alternate lifting motions in opposite directions at the same time.
Specifically, in this embodiment, the working principle of the multilayer stepped lifting plate feeding mechanism is as follows: referring to fig. 4, when the second step lift assembly 500 is in the lower position, the reaction cup is positioned on the top edge thereof, and simultaneously, the first step lift assembly 400 is in the upper position; referring to fig. 5, when the second step lift assembly 500 moves upwards, the first step lift assembly 400 moves downwards, the reaction cup is jacked up by the second step lift assembly 500, then is higher than the first step lift assembly 400, and slides downwards along the second guide surface 501a at the top of the reaction cup to the top edge of the first step lift assembly 400, and the reaction cup spans a plate thickness; referring to fig. 4, conversely, when the second step lift assembly 500 moves downwards, the first step lift assembly 400 moves upwards to jack up the reaction cup and slide the reaction cup along the first guide surface 401a onto the second step lift assembly 500, and the reaction cup again crosses a plate thickness; thus, the reaction cups at the bottom of the storage bin 200 can be gradually jacked up into the sequencing runner 300 through the alternate up-and-down staggered movement of the first ladder lifting assembly 400 and the second ladder lifting assembly 500; because the stroke of the lifting staggered movement of the two is shorter, the circulation times of completing the alternate movement and ejecting the reaction cups are more in the same time, and the number of the reaction cups ejected in unit time of the feeding mechanism is greatly increased.
In some embodiments, in order to ensure that the reaction cups are smoothly conveyed toward the sequencing batch flow path 300 during the staggered ascending and descending motion of the first and second step-lifting assemblies 400 and 500, the first guide surface 401a and the second guide surface 501a are inclined toward the sequencing batch flow path 300. In this way, after the reaction cups are jacked up, the reaction cups can slide across a plate thickness by using the height difference between the adjacent reaction cups and the inclination of the first guide surface 401a and the second guide surface 501a, and thus can move in a direction of approaching the sequencing batch channel 300.
And, in order to ensure the orderliness in the transportation process, the distance between the adjacent first step boards 401 or the adjacent second step boards 501 only contains one material. In this embodiment, the distance between the adjacent first step plates 401 or the distance between the adjacent second step plates 501 is greater than the diameter of a single cuvette and less than the length of a single cuvette.
In some embodiments, referring to fig. 4 to 6, the first step plates 401 and the second step plates 501 are both L-shaped, a plurality of the first step plates 401 are connected by a first connecting plate 402, a plurality of the second step plates 501 are connected by a second connecting plate 502, and the first step plates 401 and the second step plates 501 are arranged in a staggered manner. Specifically, the distance between adjacent first step plates 401 is suitable for accommodating one plate thickness of the second step plate 501, and a certain gap is provided, so that the second step plate 501 can smoothly rise or fall without interference; the distance between the adjacent second step plates 501 is suitable for accommodating a plate thickness of the first step plate 401, and has a certain gap, so that the first step plate 401 can smoothly ascend or descend without interference. For ease of manufacture, the first step plate 401 and the second step plate 501 may be provided with the same thickness.
In some embodiments, the long L-shaped edge of the first step 401 may be overlapped on the second connecting plate 502, and the long L-shaped edge of the second step 501 may be overlapped on the first connecting plate 402. Specifically, a plurality of first step plates 401 and second step plates 501 are arranged oppositely, the L-shaped short edges of the first step plates 401 are connected to the first connecting plate 402, and the first connecting plate 402 between adjacent first step plates 401 is used for overlapping the corresponding second step plates 501, so that the L-shaped long edges of the second step plates 501 are conveniently overlapped; the L-shaped short side of the second step plate 501 is connected to the second connecting plate 502, and the second connecting plate 502 between the adjacent second step plates 501 is used for overlapping the corresponding first step plate 401, so that the L-shaped long side of the first step plate 401 is overlapped.

Thus, when the driving motor 601 drives the driving belt 604 to move, the first step-lift assembly 400 and the second step-lift assembly 500 connected to both sides of the driving belt 604 move in opposite directions, respectively. That is, when the driving motor 601 rotates in the first direction, the first step lift assembly 400 ascends and the second step lift assembly 500 descends; when the driving motor 601 rotates in the reverse direction to the first direction, the first step lift assembly 400 descends, and the second step lift assembly 500 ascends; so that the alternate elevating motion of driving the first and second step elevating assemblies 400 and 500 can be achieved.
In order to connect and fix the first step lifting assembly 400 and the second step lifting assembly 500 with the transmission belt 604, a first clamping block 403 is arranged on one side of the first step lifting assembly 400, a second clamping block 503 is arranged on one side of the second step lifting assembly 500, the first step lifting assembly 400 is clamped with the transmission belt 604 through the first clamping block 403, and the second step lifting assembly 500 is clamped with the transmission belt 604 through the second clamping block 503.

Because the first step lifting assembly 400 and the second step lifting assembly 500 are respectively fixed on the guide rail 700 through the first sliding block 404 and the second sliding block 504, the problem that chips fall off due to dry friction of parts is avoided, and the problem that chips fall off due to abrasion of a bin bottom disturbing mechanism in the prior art is solved.
In addition, a material blocking rod 506 is arranged on one side, close to the sequencing flow channel 300, of the first step lifting assembly 400 or the second step lifting assembly 500, and the material blocking rod 506 is used for adjusting the posture of the material to be in a vertical state. In some embodiments, the material blocking rod 506 is located on the second step lifting assembly 500 and reciprocates up and down along with the second step lifting assembly 500, so that each reaction cup is blocked by the material blocking rod 506 after entering the sequencing flow channel 300, and the lifting motion of the material blocking rod 506 acts on the reaction cup, so that the postures of the reaction cups are uniformly adjusted to be vertical, and then the reaction cups slide down continuously, and the reaction cups are prevented from being turned over, rolled and clamped in the sequencing flow channel 300 to cause faults.
