Description

Technical Field

[0001] The present invention relates to the technical field of in vitro diagnostic equipment, in particular to a high-speed automatic loading mechanism for a reaction container for in vitro diagnosis. Background Art

[0002] In in vitro diagnostic equipment, such as coagulation and chemiluminescence immunoassay analyzers, due to their high repeatability requirements, in order to avoid residual and carryover contamination, reaction cups are not allowed to be reused, and disposable reaction cups must be used. In order to achieve fully automated operation of chemiluminescence detection tests, a large number of disordered disposable reaction cups put into the hopper must be made orderly. It is necessary to develop an automatic reaction cup loading mechanism to realize automatic reaction cup sorting, loading, and feeding.

[0003] Patent publication number "CN104076161A" discloses "an analysis device capable of stably supplying cuvettes even when a user arbitrarily inserts a plurality of cuvettes into a storage unit. The analysis device comprises: a storage unit for storing the plurality of inserted cuvettes; a removal unit for removing the cuvettes from the storage unit; and a vibrating unit for vibrating the storage unit to move the cuvettes within the storage unit."

[0004] In the above patents, the push plate type cup feeding is prone to accumulation when there is too much material in the hopper and the material cannot be hung or discharged. The push plate and the hopper outlet are easily stuck, resulting in material blockage, which requires manual intervention. The turntable type cup feeding has a complex structure and high cost, and is prone to cup jamming at the rail entry, resulting in material blockage, which requires manual intervention. The cup loading speed is slow and cannot meet the requirements of high-speed automation. The crawler type cup feeding has a slow cup loading speed and has the disadvantages of carrying the cup across the rail. It has a complex structure and high cost. The cup box pre-arrangement cup feeding method is inflexible and inefficient, which cannot meet the requirements of full automation.

[0005] To this end, the present invention provides a high-speed automatic loading mechanism for in vitro diagnostic reaction containers to solve the above-mentioned problems. Summary of the Invention

It includes a swing block, a swing block bracket, a reset spring, a current limiting block, a connecting rod, a current limiting block bracket, a current limiting baffle, a stirring block and a guide plate. The swing block is driven by the rotating module to reciprocate up and down.

The stirring block stirs the reaction cups in the feeding bin. The guide plate makes the downward direction of the reaction cups parallel to the direction of the track. The reset spring makes the swing module return to the initial position after power is cut off.

[0011] Furthermore, the descending track module is connected with the swing module, so that the reaction cup uses gravity to enter the track groove in an orderly manner and slide down to the designated position, including a descending track, a track cover, a track positioning axis, a full cup sensor and a cup exhaustion sensor; the functional areas of the descending track include a docking area, a positioning area, a buffer area, a full cup sensing area, a cup exhaustion sensing area and a conveying area; the feeding bin is used to store the reaction cup, including a storage area, a collection area, a swing block activity area, an anti-interference guide angle, an edge guard and a fixed column.

[0020] The present invention provides a high-speed automatic loading mechanism for in vitro diagnostic reaction vessels. Compared with the prior art, it has the following advantages:

[0021] 1. This high-speed automatic loading mechanism for in vitro diagnostic reaction vessels can achieve high-speed, fully automatic loading of reaction cups through the coordinated operation of a rotating module, a swing module, a downward track module, and a feeding bin. The swing block, driven by the rotating module, rapidly reciprocates, allowing the reaction cups to enter the downward track in an orderly manner. Combined with the efficient conveying design of the downward track, this greatly shortens the loading time of the reaction cups, significantly improves the detection efficiency of in vitro diagnostic equipment, and can meet the demand for rapid results in modern medical testing.

[0022] 2. The high-speed automatic loading mechanism for in vitro diagnostic reaction vessels is designed with multiple anti-cup jamming structures. The flow-limiting block, flow-limiting baffle, and stirring block in the swing module work together to prevent too many reaction cups from entering the guide channel at the same time, and also prevent the reaction cups from accumulating and getting stuck. The docking area design of the descending track, the height control of the track cover, and the guidance of the reaction cup direction by the guide plate all effectively prevent the reaction cup from getting stuck during movement, greatly improving the stability and reliability of the equipment operation and reducing equipment failures and downtime caused by cup jams.

[0023] 3. The in vitro diagnostic reaction vessel has a high-speed automatic loading mechanism, and the eccentric wheel module of the rotation module is equipped with an overload protection function. When the cup is stuck, the eccentric wheel module can cause the motor to idle, and the torque is controlled by the cooperation of springs and balls to protect the motor and various components from damage. This design reduces the frequency of equipment component damage due to malfunctions, reduces maintenance costs, extends the service life of the equipment, and improves the overall cost-effectiveness of the equipment.

[0044] The top shape of the stirring block 3-8 is consistent with the shape of the feeding bin 5, the arc curve is set with the rotating shaft as the center, the distance between the front end groove and the feeding bin 5 is 1-2 cup lengths, and the angles of the baffles on both sides of the stirring block 3-8 are perpendicular to the horizontal plane or greater than 90°.

The anti-interference guide angle of the feeding hopper 5 is a chamfered structure at the junction of the collection area and the swing block 3-1 in the swing module 3.

[0047] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0048] Working principle: The support module lays the foundation: The support module serves as the structural foundation of the entire mechanism and plays a key role in stably supporting other modules; the main support plate 1-1 is fixed on the frame bracket 1-6, and the height of the mechanism can be fine-tuned through the positioning waist hole of the frame bracket 1-6 and the fine-tuning bracket 1-2, while ensuring that the relative positions of the modules are accurate and unchanged; the positioning support plate 1-4 accurately guides the installation of the auxiliary support plate 1-3 and the swing module with the positioning pins on the upper and lower surfaces; the positioning pins at the joint of the auxiliary support plate 1-3 and the rotation module further ensure the accuracy of the installation of the rotation module; the feeding bin bracket 1-7 is installed on both sides of the main and auxiliary support plates to firmly fix the feeding bin 5, providing a stable physical support structure for the entire loading process;

[0049] The rotating module provides power drive: The rotating module is the power source of the entire loading mechanism; after the rotating motor 2-1 is started, it drives the eccentric wheel module 2-3 fixed to it to rotate at high speed; the eccentric bearing 2-3-6 of the eccentric wheel module 2-3 extends into the waist-shaped groove of the swing block 3-1 in the swing module. As the eccentric wheel module 2-3 rotates, the eccentric bearing 2-3-6 moves in the waist-shaped groove, thereby driving the swing block 3-1 to reciprocate up and down;

[0050] Overload protection mechanism: The eccentric wheel module 2-3 has an important overload protection function. Its rotating spindle 2-3-1 is equipped with three slots evenly spaced at 120 degrees. The slots contain the overload protection spring 2-3-3 and the ball 2-3-4. The eccentric wheel 2-3-2 is designed with a wavy circular hole inside to match the ball 2-3-4. When an abnormality such as a stuck cup occurs, the eccentric wheel 2-3-2 cannot rotate normally. At this time, the rotating spindle 2-3-1 drives the compressed spring and ball 2-3-4 to rotate along the wavy circular hole. By properly setting the compression distance and number of springs, the torque can be effectively controlled, preventing damage to the motor and other components due to excessive resistance, and ensuring the safe and stable operation of the equipment.

[0051] Position monitoring and control: The position sensor 2-4 and the sensor baffle 2-5 work together to monitor the motion state of the swing module in real time. The on-off time between the position sensor 2-4 and the sensor baffle 2-5 can be used to determine whether a cup jam has occurred. At the same time, the on-off signal from the position sensor 2-4 can be used to precisely control the motion range of the swing module, ensuring its accuracy and stability.

[0052] The swing module enables orderly organization and transportation of reaction cups: the swing block 3-1 reciprocates up and down under the drive of the rotation module. When the swing block 3-1 moves upward, the reaction cups in the feeding bin 5 enter the channel composed of the flow-limiting block 3-4, the swing block 3-1, and the flow-limiting baffle 3-7 under the action of gravity and the stirring block 3-8. This channel can effectively limit the number of reaction cups entering the guide groove, preventing excessive influx of reaction cups and causing cup jams. The swing block 3-1 and the flow-limiting block 3-4 are connected by a connecting rod 3-5 to ensure that the channel size remains consistent during the reciprocating motion, ensuring that the reaction cups can enter the guide groove stably and smoothly.

[0053] Stirring and preventing accumulation: The stirring block 3-8 fixed on the upper part of the flow limiting block 3-4 plays a key role in the reciprocating swing process of the swing module; the top shape of the stirring block 3-8 is consistent with the shape of the feeding bin 5, and its arc curve is set with the rotating shaft as the center. The front groove maintains a space of 1-2 cup lengths with the feeding bin 5, and the angles of the baffles on both sides are perpendicular to the horizontal plane or greater than 90°. This design enables the stirring block 3-8 to fully stir the reaction cups in the feeding bin 5 when swinging, preventing the reaction cups from accumulating and getting stuck, and ensuring that the reaction cups enter the guide groove smoothly;

[0054] Guide positioning: The guide plate 3-9 is fixed to the tail end of the current limiting block 3-4 and reciprocates synchronously with the current limiting block 3-4. When the reaction cup slides down to the docking point with the sliding track, the guide plate 3-9 can guide the reaction cup so that its direction is parallel to the direction of the sliding track, effectively preventing the reaction cup cap from getting stuck with the sliding track cover 4-2. The shape of the guide plate 3-9 can be selected as a straight plate or a Z-shaped two-fold structure according to actual needs. The gaps reserved on both sides facilitate manual handling when the cup is stuck. The reset spring 3-3 takes effect after the swing module is powered off, allowing the swing module to quickly return to its initial position to prepare for the initialization operation of the next loading process.

[0055] The descending track module completes the transport and monitoring of the cuvettes: the descending track module is tightly connected to the swing module, using the cuvettes' own gravity to achieve their orderly descent. The docking area of the descending track 4-1 is set at a certain angle, and the connection with the swing block 3-1 adopts a smooth transition design with a maximum gap of no more than 1mm. This prevents interference between the swing block 3-1 and the descending track 4-1 while ensuring that the cuvettes can smoothly enter the descending track 4-1 from the swing module.

[0056] Track positioning and buffering: The positioning area of the descending track 4-1 cooperates with the positioning pins of the main support plate 1-1 and the auxiliary support plate 1-3 in the support module and the track positioning shaft 4-3 to accurately ensure the connection position between the track docking area and the swing block 3-1; the buffer area can store a certain number of reaction cups. When the reaction cups in the feeding bin 5 are exhausted, the reaction cups in the buffer area can maintain the normal operation of the machine for a period of time. The number of buffered cups can be set according to actual usage needs;

[0057] Cup quantity monitoring and control: The full cup sensor 4-4 set in the full cup sensing area and the cup exhaustion sensor 4-5 set in the cup exhaustion sensing area respectively monitor the number of reaction cups in the buffer area in real time; when the full cup sensor 4-4 detects that the buffer area is full of cups, it will send a signal to stop the swing module to prevent the reaction cups from continuing to enter and causing congestion; when the full cup sensor 4-4 detects that there are no cups in the buffer area, the swing module continues to run and replenishes the reaction cups; when the cup exhaustion sensor 4-5 is activated, it indicates that there are no available reaction cups in the feeding bin 5 and the buffer area. At this time, the machine will stop running to avoid idling of the equipment or other abnormal situations; the conveying area can be designed into various shapes such as straight line, circle, S shape, etc. according to different functional requirements to transport the reaction cups to the designated detection or use position; the track cover 4-2 is installed on the downward track 4-1, and its height is slightly higher than the reaction cup cap by 0.5-1.0mm, which can ensure that the reaction cups are arranged side by side in an orderly manner, effectively limit the stacking of reaction cup caps, and prevent the reaction cups from sliding down or getting stuck;

[0058] The feeding hopper stores and supplies reaction cups: the feeding hopper 5 is mainly used to store reaction cups; the storage area can be designed into various shapes such as rectangle, square, circle, trapezoid, etc. according to actual needs to meet the storage needs of reaction cups of different quantities and specifications; the collection area adopts a conical or conical circular design, and the ratio of the cone diameter to the cone height is controlled within the range of 1.5-2, and the center of the cone diameter is set at the tangent position of the swing block 3-1 in the swing module. Such a design can effectively reduce the number of residual cups in the hopper, or even achieve no residual cups; the anti-interference guide angle is a chamfer treatment structure at the junction of the collection area and the swing block 3-1, which can avoid the reaction cup and the feeding hopper 5 from getting stuck during the swinging process of the swing block 3-1. This structure is an optional design, and even if it is not there, it will not affect the basic function of the feeding hopper; the edge guards are located on both sides of the hopper to prevent the reaction cups from falling, and the fixed column is used to firmly fix the feeding hopper on the support module to ensure its stability during the entire loading process.
