Description

Technical Field

[0001] The present invention relates to the technical field of in vitro diagnostic devices, and specifically to a high-speed automatic loading mechanism for reaction containers used in in vitro diagnosis. Background Art

[0002] In in vitro diagnostic devices, such as coagulation and chemiluminescence immunoassay analyzers, due to their high repeatability requirements, in order to avoid residue and carry-over contamination, disposable reaction cups are not allowed to be reused. To achieve fully automated operation of chemiluminescence detection tests, a large number of disordered disposable reaction cups in the input bin need to be made orderly. It is necessary to develop an automatic loading mechanism for reaction cups to realize actions such as automatic cup sorting, cup feeding, and cup entering.

[0003] The "Analysis Device" disclosed in Patent Publication No. "CN104076161A" has: a storage component for storing a plurality of reaction cups placed therein, a taking-out component for taking out the reaction cups in the storage component from the storage component, and a vibrating component for moving the reaction cups in the storage component by vibrating the storage component. In the above patent, for the push-plate type cup feeding, when there is too much material in the bin, it is easy to produce accumulation and unable to hang and discharge the material. The push plate is easily stuck at the position of the bin outlet, resulting in material blockage and requiring manual intervention. For the turntable type cup feeding, the structure is complex, the cost is high, and it is easy to get stuck at the cup inlet, resulting in material blockage and requiring manual intervention. The cup feeding speed is slow and cannot meet the requirements of high-speed automation. For the caterpillar type cup feeding, the cup feeding speed is slow, and there are disadvantages such as carrying the cup across the track. The structure is complex, the cost is high, and the cup box pre-arrangement cup feeding method is not flexible and the efficiency is low, and it cannot meet the requirements of full automation.

[0004] Therefore, the present invention provides a high-speed automatic loading mechanism for reaction containers used in in vitro diagnosis to solve the above problems. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention provides a high-speed automatic loading mechanism for reaction containers used in in vitro diagnosis, which solves the above problems.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: A high-speed automatic loading mechanism for reaction containers used in in vitro diagnosis, including a support module, a rotation module, a swing module, a sliding track module, and a feeding bin: The support module is used to support other modules, including a main support plate, a fine-tuning bracket, a secondary support plate, a positioning support plate, positioning columns, a frame bracket, and a feeding bin bracket. The main support plate is fixed to the frame bracket. The main support plate is provided with a frame bracket positioning pin and a downward sliding track positioning pin. The frame bracket is provided with positioning waist holes. Both the upper and lower surfaces of the positioning support plate are provided with positioning pins. The secondary support plate is assembled through the positioning pins of the positioning support plate. Two positioning pins are provided at the docking position between the secondary support plate and the rotating module. The feeding bin bracket is installed on both sides of the main support plate and the secondary support plate to fix the feeding bin. The rotating module drives the swinging module to perform reciprocating motion through the rotation action of the motor, and includes a rotating motor, a motor bracket, an eccentric wheel module, a position sensor, a sensor baffle, and a sensor bracket. The eccentric wheel module is fixed to the rotating motor. The rotating motor and the position sensor are fixed to the motor bracket. The eccentric bearing of the eccentric wheel module extends into the waist-shaped groove of the swinging block of the swinging module. The eccentric wheel module has an overload protection function. The swinging module makes the disordered reaction cups in the feeding bin enter the downward sliding track orderly through up-and-down swinging, and includes a swinging block, a swinging block bracket, a return spring, a current-limiting block, a connecting rod, a current-limiting block bracket, a current-limiting baffle, a stirring block, and a guiding plate. The swinging block is driven by the rotating module to perform reciprocating up-and-down motion. The current-limiting block, the swinging block, and the current-limiting baffle form a channel to limit the number of reaction cups entering. The stirring block stirs the reaction cups in the feeding bin. The guiding plate makes the sliding direction of the reaction cups parallel to the track direction. The return spring makes the swinging module return to the initial position after power-off.

[0007] Further, the downward sliding track module is connected to the swinging module, so that the reaction cups enter the track groove orderly by gravity and slide to the specified position, and includes a downward sliding track, a track cover plate, a track positioning shaft, a full cup sensor, and a cup depletion sensor. The functional areas of the downward sliding track include a docking area, a positioning area, a buffer area, a full cup sensing area, a cup depletion sensing area, and a conveying area. The feeding bin is used to store reaction cups and includes a storage area, a gathering area, a swinging block activity area, an anti-interference guiding angle, a protective edge, and fixing columns.

[0008] Further, the eccentric wheel module includes a rotating main shaft, an eccentric wheel, an overload protection spring, a ball, a cover plate, and an eccentric bearing. The rotating main shaft is provided with three card slots evenly distributed at 120° for placing springs and balls. The inside of the eccentric wheel is provided with a wavy round hole that cooperates with the balls. The cover plate is fixed to the rotating main shaft to limit the moving positions of the overload protection spring and the balls.

[0009] Further, the swinging block is connected to the current-limiting block through a connecting rod to ensure that the channel size formed by the current-limiting block, the swinging block, and the current-limiting baffle remains unchanged during the reciprocating motion.

[0010] Furthermore, the top shape of the stirring block fits the shape inside the feeding bin. The arc curve is centered on the rotating shaft. The distance between the front slot part and the feeding bin is a space of 1-2 cup lengths. The angles of the baffle plates on both sides of the stirring block are perpendicular to the horizontal plane or greater than 90°.

[0011] Furthermore, the guide plate is fixed to the tail of the flow-limiting block and reciprocates synchronously with the flow-limiting block. The shape of the guide plate is a straight plate, a Z-shaped two-fold structure or other extended structures. Gaps are reserved on both sides of the guide plate.

[0012] Furthermore, the docking area of the downward sliding track is set at a certain inclination angle, and the connection with the swinging block is smoothly transitioned. The maximum gap does not exceed 1 mm.

[0013] Furthermore, the height of the track cover plate and the track groove of the downward sliding track is slightly higher than the reaction cup cap, and the height difference is 0.5-1.0 mm.

[0014] Furthermore, the converging area of the feeding bin is conical or conical-round. The ratio of the conical-round diameter to the conical height in the converging area is within the range of 1.5-2. The center of the conical-round diameter in the converging area is set at the tangent position where the swinging block in the swinging module swings.

[0015] Furthermore, the anti-interference guiding angle of the feeding bin is a chamfering structure at the connection between the converging area and the swinging block in the swinging module.

[0016] The present invention provides a high-speed automatic loading mechanism for reaction containers used in in vitro diagnosis. Compared with the prior art, it has the following beneficial effects: 1. For the high-speed automatic loading mechanism for reaction containers used in in vitro diagnosis, through the coordinated operation of the rotating module, swinging module, downward sliding track module and feeding bin, high-speed full-automatic loading of reaction cups can be achieved. The swinging block reciprocates rapidly under the drive of the rotating module, enabling the reaction cups to enter the downward sliding track orderly. With the efficient conveying design of the downward sliding track, the loading time of the reaction cups is greatly shortened, the detection efficiency of in vitro diagnostic equipment is significantly improved, and the demand for rapid result output in modern medical detection can be met.

[0017] 2. For the high-speed automatic loading mechanism for reaction containers used in in vitro diagnosis, multiple anti-cup jamming structures are designed. The flow-limiting block, flow-limiting baffle plate and stirring block in the swinging module cooperate with each other to prevent too many reaction cups from entering the diversion groove at the same time and also prevent the reaction cups from piling up and getting stuck. The design of the docking area of the downward sliding track, the control of the height of the track cover plate, and the guiding of the direction of the reaction cups by the guide plate all effectively avoid the situation of the reaction cups getting stuck during movement, greatly improving the stability and reliability of the equipment operation and reducing equipment failures and downtime caused by cup jamming.

[0018] 3. The high-speed automatic loading mechanism for the reaction vessel used in in vitro diagnosis. The eccentric wheel module of the rotation module is equipped with an overload protection function. When a cup jamming occurs, the eccentric wheel module can make the motor rotate idly, control the torque through the cooperation of the spring and the ball, protect the motor and various components from being damaged. This design reduces the frequency of component damage due to equipment failures, reduces the maintenance cost, extends the service life of the equipment, and improves the overall cost performance of the equipment.

[0030] Meanwhile, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0031] Working principle: The support module lays the foundation: The support module serves as the architectural 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 support 1-6. Through the positioning waist holes of the frame support 1-6 and the fine-tuning support 1-2, the height of the mechanism can be finely adjusted, while ensuring that the relative positions of each module remain precisely unchanged; the positioning support plate 1-4, with positioning pins on its upper and lower surfaces, accurately guides the installation of the secondary support plate 1-3 and the swing module; the positioning pins at the docking position of the secondary support plate 1-3 and the rotation module further ensure the accuracy of the rotation module installation; the feeding bin support 1-7 is installed on both sides of the main and secondary support plates, firmly fixing the feeding bin 5, providing a stable physical support structure for the entire loading process; The rotation module provides power drive: The rotation module is the power source of the entire loading mechanism; after the rotation motor 2-1 starts, it drives the eccentric wheel module 2-3 fixedly connected 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 perform reciprocating up and down motion; Overload protection mechanism: The eccentric wheel module 2-3 has an important overload protection function; its rotating main shaft 2-3-1 is provided with three evenly distributed slots at 120°. Overload protection springs 2-3-3 and balls 2-3-4 are placed in the slots. The eccentric wheel 2-3-2 is internally designed with a wavy round hole that cooperates with the ball 2-3-4; when abnormal situations such as cup jamming occur, the eccentric wheel 2-3-2 cannot rotate normally. At this time, the rotating main shaft 2-3-1 drives the compressed spring and the ball 2-3-4 to rotate along the wavy round hole; by reasonably setting the compression distance and quantity of the spring, the torque can be effectively controlled, avoiding damage to the motor and other components due to excessive resistance, and ensuring the safe and stable operation of the equipment; Position monitoring and control: The position sensor 2-4 and the sensor baffle 2-5 cooperate with each other to monitor the motion state of the swing module in real time; according to the length of the on-off time between the position sensor 2-4 and the sensor baffle 2-5, it can be judged whether a cup jamming phenomenon occurs; at the same time, using the on-off signal of the position sensor 2-4, the motion range of the swing module can be accurately controlled to ensure the accuracy and stability of its motion; The swing module realizes the orderly arrangement 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 diversion trough and prevent carding caused by too many reaction cups pouring in; 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 stably and smoothly enter the diversion trough; Stirring to prevent accumulation: The stirring block 3-8 fixed on the upper part of the flow-limiting block 3-4 plays a key role during the reciprocating swing of the swing module; the top shape of the stirring block 3-8 matches the shape inside the feeding bin 5, its arc curve is set with the rotating shaft as the center, the front groove part keeps a space of 1-2 cup lengths from the feeding bin 5, and the angles of the two side retaining plates are perpendicular to the horizontal plane or greater than 90°; such a design enables the stirring block 3-8 to fully stir the reaction cups in the feeding bin 5 during swinging, preventing the reaction cups from accumulating and jamming, and ensuring that the reaction cups smoothly enter the diversion trough; Guiding and positioning: The guiding plate 3-9 is fixed at the tail of the flow-limiting block 3-4 and reciprocates synchronously with the flow-limiting block 3-4; when the reaction cup slides down to the docking area with the downward sliding track, the guiding plate 3-9 can guide the reaction cup to make its direction parallel to the direction of the downward sliding track, effectively preventing the reaction cup cap from jamming with the cover plate 4-2 of the downward sliding track; the shape of the guiding plate 3-9 can be selected as a straight plate, a Z-shaped double-fold structure or other extended structures according to actual needs, and the gaps reserved on both sides facilitate manual handling in case of cup jamming; the return spring 3-3 plays a role after the swing module is powered off, enabling the swing module to quickly return to the initial position and preparing for the initialization operation of the next loading process; The downward sliding track module completes the transportation and monitoring of reaction cups: The downward sliding track module is closely connected with the swing module, and uses the self-gravity of the reaction cups to achieve their orderly downward sliding; the docking area of the downward sliding track 4-1 is set at a certain inclination angle, and the connection with the swing block 3-1 adopts a smooth transition design, with the gap controlled to be no more than 1 mm at most, while avoiding interference between the swing block 3-1 and the downward sliding track 4-1, ensuring that the reaction cups can smoothly enter the downward sliding track 4-1 from the swing module; Track positioning and caching: The positioning area of the downward sliding track 4-1 is accurately guaranteed to be in the correct connection position with the swing block 3-1 through 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; the caching 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 caching area can maintain the normal operation of the machine for a period of time, and the caching quantity can be set according to actual usage requirements; Cup Quantity Monitoring and Control: The full cup sensor 4-4 set in the full cup sensing area and the cup depletion sensor 4-5 set in the cup depletion 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 operation of 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 will continue to operate to replenish the reaction cups. When the cup depletion 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 or other abnormal conditions of the equipment. The conveying area can be designed into various shapes such as linear, circular, S-shaped, etc. according to different functional requirements to convey the reaction cups to the designated detection or use positions. The track cover plate 4-2 is installed on the upper part of the sliding track 4-1, and its height is preferably slightly higher than the reaction cup cap by 0.5-1.0 mm, which can ensure that the reaction cups are arranged side by side in an orderly manner, effectively limit the stacking of reaction cup caps with each other, and prevent affecting the sliding of the reaction cups or causing cup jamming phenomena. Feeding Bin Storage and Supply of Reaction Cups: The feeding bin 5 is mainly used for storing reaction cups. The storage area can be designed into various shapes such as rectangular, square, circular, trapezoidal, etc. according to actual needs to meet the storage requirements of reaction cups with different quantities and specifications. The converging area is designed in a conical or conical circular shape, and the ratio of the conical circular diameter to the conical height is controlled within the range of 1.5-2, and the center of the conical circular diameter is set at the tangent position of the swing of the swing block 3-1 in the swing module. Such a design can effectively reduce the number of residual cups in the bin, and even achieve no residual cups. The anti-interference guiding angle is a chamfering treatment structure at the junction of the converging area and the swing block 3-1, which can avoid the phenomenon of the reaction cups being stuck with the feeding bin 5 during the swing of the swing block 3-1. This structure is an optional design, and even without it, it does not affect the basic function of the feeding bin. The edge guards are located on both sides of the bin to prevent the reaction cups from falling, and the fixing columns are used to firmly fix the feeding bin on the support module to ensure its stability during the entire loading process.
