Description

Technical Field

[0001] This invention relates to the field of visual inspection and delivery technology, specifically to a reagent kit delivery device capable of visual inspection. Background Technology

[0002] In fields such as biomedicine, clinical testing, and food safety, reagent kits serve as the core carriers of reagents, samples, and detection components, and their quality directly affects the accuracy and reliability of test results. As the industry's requirements for testing efficiency and precision continue to increase, the production scale of reagent kits is constantly expanding, making the inspection of their appearance and the integrity of internal components a critical step in the production process.

[0003] Traditional reagent kit testing primarily relies on manual operation. Testers visually inspect the kit for defects such as scratches, deformation, and stains, and manually open the lid to check the cleanliness of the internal cavity and the presence of missing components. However, manual testing has several limitations: First, it is highly subjective, with results easily influenced by the tester's experience, fatigue, and visual state. Inconsistent testing standards between different personnel or even the same person at different times lead to poor defect identification and a high rate of false positives and false negatives. Second, testing efficiency is low. The manual process of opening, observing, and closing the lid is cumbersome, and testing a single kit is time-consuming, failing to meet the needs of large-scale production. Third, improper control of opening force during manual operation can easily cause deformation or surface damage to the kit or lid, and prolonged repetitive work can lead to personnel fatigue, further exacerbating the instability of testing quality.

[0004] To address the drawbacks of manual inspection, some companies have attempted to automate the process by using simple conveying equipment combined with a single vision inspection device. However, existing equipment still has significant shortcomings: Firstly, most equipment can only perform visual inspection and cannot automatically open and close the lid. Internal component inspection still requires manual assistance, failing to achieve full automation. Secondly, the few devices with lid-opening functions often use rigid clamping mechanisms, which can easily damage the reagent kits and have insufficient positioning accuracy, resulting in the internal cavity not being fully exposed to the inspection field after opening, creating blind spots. Furthermore, the existing equipment lacks coordinated linkage between conveying positioning and inspection, as well as opening and closing actions, requiring multiple independent drive components and complex control logic. This not only increases the complexity of the equipment structure and the risk of failure but also raises manufacturing costs and maintenance difficulties. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides a visually inspectable reagent delivery device to solve the problems mentioned in the background art.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the present invention provides the following technical solution: a visually inspectable reagent delivery device, comprising: a main support and a visual inspection module, a sorting module and a film encapsulation module mounted on the main support;

[0009] The main support frame is equipped with a conveyor belt driven by a speed-regulating motor for transporting the reagent kits to be packaged.

[0010] The visual inspection module is used to perform visual inspection on the reagent kits during the transport process, and includes a positioning unit, an opening and closing unit, and an industrial camera. The industrial camera is used to visually inspect the appearance defects of the reagent kits transported by the conveyor belt. The positioning unit includes two positioning clamps for positioning the sides of the reagent kits. The opening and closing unit is used to open or close the lid of the reagent kit. When the lid is opened, the interior of the reagent kit is inspected by the industrial camera. When the lid is closed, the inspected reagent kit is transported to the next process by the conveyor belt.

[0011] Preferably, a stop cylinder is fixedly connected to the main support via a bracket, and a stop plate is fixedly connected to the telescopic end of the stop cylinder, which is used to stop the transported reagent kit by driving the stop plate through the stop cylinder, thereby forming an equidistant transport of several reagent kits.

[0012] Both sides of the conveyor belt are equipped with adjustable anti-deviation baffles, and the distance between the two anti-deviation baffles is adapted to the width of the reagent kit.

[0013] Preferably, the opening and closing unit includes two sets of support frames mounted on the main support and a rotary motor fixed on one of the support frames. The industrial camera is mounted between the two support frames via a mounting bracket. A material-picking component for connecting the lid of the reagent kit is provided between the two support frames. The rotary motor is used to drive the lid to rotate in a ring shape through the material-picking component, so that the interior of the reagent kit is completely exposed to the field of view of the industrial camera.

[0014] Preferably, the material handling component includes a multi-shaped rod rotatably connected between two support frames. The multi-shaped rod is equipped with a plurality of negative pressure suction nozzles for adsorbing the lid by negative pressure. The rotary motor is used to rotate the multi-shaped rod to cause the lid fixed by the negative pressure suction nozzles to flip.

[0015] Preferably, the rods include a U-shaped rod and two L-shaped rods;

[0016] Two L-shaped rods are rotatably connected to two support frames, and the output shaft of the rotary motor is fixedly connected to one of the L-shaped rods through a coupling; the two ends of the U-shaped rod are connected to the inside of the two L-shaped rods in a sealed sliding manner, and each of the two L-shaped rods is equipped with a pneumatic connection nozzle for connecting to an external air pump to drive the extension and retraction of the U-shaped rod, forming the fitting or separation of the cover and the box.

[0017] The U-shaped rod has a negative pressure chamber inside, and several negative pressure suction nozzles are connected to the inside of the negative pressure chamber. The U-shaped rod is also connected to a negative pressure connection nozzle for connecting to an external negative pressure pump, forming a negative pressure suction and fixation of the lid by the negative pressure suction nozzles.

[0018] Preferably, the positioning unit further includes two transmission frames, which are slidably connected to two anti-displacement baffle frames in a vertical sliding manner. Both transmission frames are inclined and are used to drive the two positioning clamping frames to move relative to each other or move apart by their own vertical movement. When the two positioning clamping frames move relative to each other, they are used to position and clamp the sides of the reagent kit box. When the two positioning clamping frames move apart, they are used to lose the positioning and clamping of the reagent kit box and hide under the anti-displacement baffle frames.

[0019] Preferably, the two positioning clamps are slidably connected to the two anti-deviation baffles via two guide rods, and the two guide rods are equipped with spring groups for elastically squeezing the positioning clamps, so that when the positioning clamps lose the downward pressing force of the transmission frame, the positioning clamps automatically retract and hide under the anti-deviation baffles.

[0020] Both positioning clamps are U-shaped, and the U-shaped openings of the positioning clamps are inclined, which is used for centering and calibrating the reagent kit to be clamped.

[0021] Preferably, both ends of the rod are fixedly connected to eccentric wheels, and both support frames are slidably connected to transmission rods in a vertical sliding manner. The bottom ends of the two transmission rods are respectively in contact with the tops of the two transmission frames, which are used to drive the transmission rods to move downward through the rotation of the eccentric wheels, thereby forming a horizontal drive of the transmission frame to the positioning clamping frame.

[0022] Preferably, the eccentric ends of the two eccentric wheels are on the same reference plane as the rod.

[0023] When the multi-type rod is in a vertically downward state, for opening or closing the lid, the two eccentric wheels drive the two positioning clamps to move in opposite directions, forming a real-time positioning clamp for the reagent kit; and when the multi-type rod is in a horizontal state, for overall defect detection or internal defect detection of the reagent kit, the two eccentric wheels lose their relative movement to the two positioning clamps, and cooperate with two sets of springs to cause the positioning clamps to retract.

[0024] (III) Beneficial Effects

[0025] Compared with the prior art, the present invention provides a visually inspectable reagent delivery device, which has the following advantages:

[0026] Comprehensive and accurate inspection with no omissions in defect identification: The equipment integrates a vision inspection module, which uses an industrial camera and professional machine vision algorithms to not only complete the appearance defect inspection during the reagent kit delivery process, but also realize the automatic flipping of the lid through the opening and closing unit to carry out all-round inspection of the internal cavity and components. It can accurately identify various defects such as scratches, deformation, stains, and missing internal components, effectively avoiding the subjective errors and omissions of traditional manual inspection, and greatly improving the reliability and consistency of inspection results.

[0027] High degree of automation and significantly improved operational efficiency: The equipment achieves fully automated operation from reagent kit delivery, equidistant positioning, automatic cap opening, internal and external testing, to sorting, rejection, and qualified packaging. Through the coordinated control of stop cylinders and photoelectric sensors, precise equidistant delivery of reagent kits is achieved; the opening and closing unit adopts a negative pressure adsorption and rotational flipping structure, ensuring smooth and efficient cap opening and closing actions; the positioning unit and opening and closing unit are linked by an eccentric wheel mechanism, achieving coordinated action without additional drive components, resulting in a continuous overall operational rhythm and significantly reducing manual intervention. Compared with traditional manual testing and processing methods, operational efficiency is effectively improved, meeting the testing and packaging needs of large-volume reagent kits.

[0028] Non-destructive design ensures product quality: The positioning clamp adopts a U-shaped inclined opening design, combined with an elastic compression spring assembly and anti-slip cushioning material, to achieve precise positioning and clamping while avoiding rigid collisions and surface damage to the reagent kit; The opening and closing unit uses a negative pressure nozzle to adsorb the lid, with controllable and uniform adsorption force and a smooth flipping process, ensuring that the lid and body fit precisely without indentations, deformation, or other damage, maximizing the preservation of the original quality of the reagent kit and reducing product loss rate.

[0029] Simplified and reliable structure, reduced operation and maintenance costs: Through the mechanical linkage design of eccentric wheel, transmission rod and transmission frame, the positioning unit and opening and closing unit are coordinated, eliminating the need for additional drive components and complex control logic, simplifying the equipment structure and control system, and reducing the probability of failure; the core components of the equipment are made of wear-resistant and corrosion-resistant materials, and are equipped with standardized components, resulting in a long service life and convenient maintenance, significantly reducing the cost of subsequent spare parts replacement and daily maintenance, saving production costs for enterprises.

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Example 1:

[0045] See attached document Figures 1 to 6 A visually inspectable reagent delivery device, comprising:

[0046] The main support 10 includes a vision inspection module, a sorting module 20, and a film encapsulation module 30 mounted on the main support 10. The sorting module 20 is used to remove unqualified reagent kits 40 after inspection by the vision inspection module. The film encapsulation module 30 is used to encapsulate qualified reagent kits 40 after inspection by the vision inspection module.

[0047] The sorting module 20 adopts the existing pneumatic sorting mechanism, equipped with a double-acting cylinder, and realizes the rapid rejection of defective products through the signal feedback of the vision detection module; the film packaging module 30 adopts heat shrink film packaging technology, with a heating temperature range of 80-150℃, temperature control accuracy of ±2℃, and the packaging speed is adjustable synchronously with the conveyor belt 11.

[0048] The main support 10 is equipped with a conveyor belt 11 driven by a speed-regulating motor (the speed-regulating motor is a three-phase asynchronous frequency conversion speed-regulating motor), which is used to transport the reagent kit 40 to be packaged. The reagent kit 40 is made of plastic and includes a box body and a box lid, which are interlocked.

[0049] The visual inspection module is used to perform visual inspection on the reagent kit 40 during the transport process. It includes a positioning unit 60, an opening and closing unit 70, and an industrial camera 50. The industrial camera 50 is used to visually inspect the appearance defects of the reagent kit 40 transported by the conveyor belt 11. The positioning unit 60 includes two positioning clamps 61 for positioning the sides of the reagent kit 40. The opening and closing unit 70 is used to open or close the lid of the reagent kit 40. When the lid is opened, the industrial camera 50 inspects the interior of the reagent kit 40. When the lid is closed, the inspected reagent kit 40 is transported to the next process by the conveyor belt 11.

[0050] The vision inspection module, as the core inspection unit, integrates the positioning unit 60, the opening and closing unit 70, and the industrial camera 50 to achieve comprehensive inspection of the appearance and internal structure of the reagent kit 40. The industrial camera 50 uses a 5-megapixel CMOS industrial camera with a frame rate ≥30fps, a lens focal length of 16mm, and a field of view of 45°. Combined with an LED ring light source (illuminance ≥2000 lux, color temperature 5500K), the optical signal is converted into a digital image signal via an image acquisition card and transmitted to the embedded processing unit (using an ARM Cortex-A9 processor with a main frequency of 1.2GHz). Based on machine vision algorithms (including sub-algorithms such as edge detection, grayscale contrast, and template matching), defect identification is achieved with a detection accuracy of up to 0.01mm. Identifiable defect types include scratches (≥0.1mm), deformations (≥0.2mm), stains (area ≥0.5mm²), and missing internal components.

[0051] The core actuators of the positioning unit 60 are two positioning clamps 61, which are made of anodized aluminum alloy and have lightweight and corrosion-resistant properties. The opening and closing unit 70 is used to realize the automatic opening and closing of the lid of the reagent kit 40. Its movement trajectory is realized through the coordinated control of the rotary motor 71 and the picking component, ensuring that the internal area is fully exposed within the effective field of view of the industrial camera 50 after the lid is opened, with no blind spots in detection.

[0052] See attached document Figures 1 to 3 A stop cylinder 12 is fixedly connected to the main support 10 via a bracket. A stop plate is fixedly connected to the telescopic end of the stop cylinder 12. The stop cylinder 12 drives the stop plate to stop the transported reagent kit 40, forming a equidistant transport of several reagent kits 40. Adjustable anti-deviation baffle frames 13 are provided on both sides of the conveyor belt 11. The distance between the two anti-deviation baffle frames 13 is adapted to the width of the reagent kit 40.

[0053] A stop cylinder 12, model SC25×50, with a working pressure of 0.4-0.8MPa, is fixedly mounted on the main support 10 via a carbon steel bracket. Its telescopic end is connected to a stop plate made of nylon with a 5mm thick cushioning rubber pad adhered to its surface to prevent rigid collisions with the reagent kit 40. The motion coordination between the stop cylinder 12 and the conveyor belt 11 is achieved through closed-loop control using a photoelectric sensor. The photoelectric sensor (diffuse reflection type, detection distance 5-30mm) is mounted above the conveyor belt 11. When the reagent kit 40 reaches the preset testing position, the sensor triggers a signal, causing the stop cylinder 12 to extend and stop the reagent kit 40. After testing is completed, the cylinder retracts, and the reagent kit 40 continues to be conveyed. This control logic ensures equidistant conveying of adjacent reagent kits 40, with a spacing error ≤ ±5mm.

[0054] The anti-deviation baffles 13 configured on both sides of the conveyor belt 11 are made of stainless steel and are slidably connected to the main support 10 through a sliding groove. The adjustment range is 50-200mm. Wear-resistant nylon strips (friction coefficient ≤0.15) are installed on the inner side and fixed by bolts. The tolerance between the two baffles and the width of the reagent kit 40 is ±1mm, which effectively limits the lateral deviation of the reagent kit 40 during the transportation process and ensures that the deviation is ≤±0.5mm.

[0055] See attached document Figures 4 to 6The opening and closing unit 70 includes two sets of support frames mounted on the main support 10 and a rotary motor 71 fixed on one of the support frames. The industrial camera 50 is mounted between the two support frames via a mounting bracket. A material-grabbing component for connecting the lid of the reagent kit 40 is provided between the two support frames. The rotary motor 71 is used to drive the lid to rotate in a ring shape through the material-grabbing component, so that the interior of the reagent kit 40 is fully exposed to the field of view of the industrial camera 50. The material-grabbing component includes a multi-shaped rod 72 rotatably connected between the two support frames. Several negative pressure suction nozzles 73 are mounted on the multi-shaped rod 72 for adsorbing the lid by negative pressure. The rotary motor 71 is used to drive the multi-shaped rod 72 to rotate, thereby driving the lid fixed by the negative pressure suction nozzles 73 to rotate.

[0056] The core component of the material handling unit is a multi-shaped rod 72, which is equipped with several negative pressure suction nozzles 73 (the number is configured according to the size of the lid). The negative pressure suction nozzles 73 are made of silicone, with an adsorption diameter of 8mm and a working negative pressure range of -0.06 to -0.08MPa. The lid is fixed non-destructively through negative pressure adsorption. A rotary motor 71 drives the multi-shaped rod 72 to rotate the lid in a ring. The rotation angle range is 0-180°, and the rotation speed can be adjusted by the servo drive parameters (0-60° / s). This ensures that after the lid is opened, the central axis of the internal cavity of the reagent kit 40 coincides with the optical axis of the industrial camera 50, with an overlap error of ≤±0.2mm. This enables clear imaging and detection of internal defects. Moreover, after rotation, the multi-shaped rod 72 is completely removed from the field of view of the industrial camera 50, improving the visual inspection effect.

[0057] See attached document Figure 5 The rod 72 includes a U-shaped rod 721 and two L-shaped rods 722. The two L-shaped rods 722 are rotatably connected to two support frames, and the output shaft of the rotary motor 71 is fixedly connected to one of the L-shaped rods 722 through a coupling. The two ends of the U-shaped rod 721 are connected to the interior of the two L-shaped rods 722 in a sealed sliding manner, and each of the two L-shaped rods 722 is provided with a pneumatic connection nozzle for connecting to an external air pump to drive the extension and retraction of the U-shaped rod 721, forming the fitting or separation of the cover and the box. The U-shaped rod 721 has a negative pressure chamber inside, and several negative pressure suction nozzles 73 are connected to the inside of the negative pressure chamber. The U-shaped rod 721 is connected with a negative pressure connection nozzle for connecting to an external negative pressure pump, forming a negative pressure adsorption fixation of the box cover by the negative pressure suction nozzles 73.

[0058] The two ends of the U-shaped rod 721 are connected to the L-shaped rod 722 internally using a sealed sliding pair structure. The sliding pair adopts a clearance fit (fit tolerance H7 / g6) and is equipped with O-rings (made of nitrile rubber) to achieve a seal and prevent air pressure leakage. The air pressure connection nozzle (interface specification G1 / 4) on the L-shaped rod 722 is connected to an external air pump (working pressure 0.6-0.8MPa). The air circuit is controlled by an electromagnetic reversing valve (model 4V210-08) to realize the extension and retraction movement of the U-shaped rod 721, and complete the fitting or separation action of the lid and the box body.

[0059] The U-shaped rod 721 has a negative pressure chamber (volume ≥ 50 cm³) machined inside. The negative pressure nozzle 73 is connected to the negative pressure chamber through an internal air passage. The negative pressure connector (interface specification G1 / 4) on the U-shaped rod 721 is connected to an external negative pressure pump. The pumping speed of the negative pressure pump is ≥ 20 L / min. The negative pressure is controlled by a negative pressure switch valve to ensure the stability of the negative pressure during adsorption. The adsorption force is ≥ 5 N, which satisfies the requirement of reliable fixation of the lid. During the adsorption process, there are no indentations, deformations or other damage to the surface of the lid.

[0060] See attached document Figure 4 and Figure 6 The positioning unit 60 also includes two transmission frames 62, which are slidably connected to two anti-displacement baffle frames 13 in a vertical sliding manner. Both transmission frames 62 are inclined and are used to drive the two positioning clamping frames 61 to move relative to each other or move apart by their own vertical movement. When the two positioning clamping frames 61 move relative to each other, they are used to position and clamp the two sides of the reagent kit 40 box. When the two positioning clamping frames 61 move apart, they lose their positioning and clamping of the reagent kit 40 box and are hidden under the anti-displacement baffle frame 13.

[0061] The two transmission frames 62 of the positioning unit 60 adopt an inclined structure design with an inclination angle of 30°. They are connected to the anti-deviation baffle frame 13 through a linear guide pair (model MGN15) to achieve vertical sliding connection. The sliding friction force is ≤5N, ensuring the smooth movement of the transmission frame 62. The vertical movement of the transmission frame 62 is driven by an external drive mechanism. Its inclined structure design transforms the vertical movement into the horizontal movement of the positioning clamping frame 61: when the transmission frame 62 moves downward, the two positioning clamping frames 61 are driven to move relative to each other through inclined surface contact, realizing the positioning clamping of both sides of the reagent kit 40 box; when the transmission frame 62 moves upward, the positioning clamping frames 61 lose driving force, move apart and hide under the anti-deviation baffle frame 13, avoiding interference with the delivery of the reagent kit 40.

[0062] The clamping force of the positioning clamp 61 on the box is controlled within the range of 5-10N through structural design, which ensures clamping stability and avoids deformation of the box due to excessive clamping force. The positioning accuracy of the box during clamping is ≤±0.1mm, ensuring the accuracy of subsequent opening and closing actions and inspection operations.

[0063] Example 2: The difference from Example 1 is that;

[0064] See attached document Figure 4 and Figure 6 Two positioning clamps 61 are slidably connected to two anti-displacement baffle frames 13 via two guide rods, and the two guide rods are equipped with spring groups 63 for elastically compressing the positioning clamps 61. When the positioning clamps 61 lose the downward pressing pressure of the transmission frame 62, the positioning clamps 61 automatically retract and hide under the anti-displacement baffle frames 13. Both positioning clamps 61 are U-shaped, and the U-shaped opening of the positioning clamps 61 is inclined, which is used for centering and calibrating the reagent kit 40 to be clamped.

[0065] Based on Example 1, this embodiment optimizes the connection structure and clamping performance of the positioning clamp 61 to further improve positioning accuracy and operational reliability.

[0066] Two positioning clamps 61 are slidably connected to the anti-deviation baffle frame 13 via guide rods, allowing the positioning clamps 61 to slide horizontally on the guide rods. A spring assembly 63 is fitted onto the guide rod; one end of the spring assembly 63 abuts against the anti-deviation baffle frame 13, and the other end abuts against the positioning clamps 61. Figure 6 The spring assembly 63 shown is in the released state, used to elastically compress the positioning clamp 61, so that the positioning clamp 61 resets and retracts when the driving force is lost. The specific principle is as follows:

[0067] When the positioning clamp 61 loses the downward pressing force of the transmission frame 62, the elastic restoring force of the spring assembly 63 drives the positioning clamp 61 to move away from the reagent kit 40 along the guide rod, automatically retracting and hiding under the anti-displacement baffle frame 13. After retraction, the top of the positioning clamp 61 is flush with the upper surface of the anti-displacement baffle frame 13, avoiding interference with the delivery of the reagent kit 40.

[0068] The positioning clamp 61 is designed with a U-shaped structure. Its U-shaped opening is angled (45°), and the inner side of the opening is rounded (2mm radius) to guide the reagent kit 40 into the clamping center, achieving centering calibration and ensuring the stability of the box when opened. A 3mm thick polyurethane anti-slip pad is attached to the clamping surface to increase friction with the box and prevent scratches or damage to the box surface during clamping. Through this structural design, the positioning clamp 61 achieves a centering calibration accuracy of ≤±0.1mm for the reagent kit 40, and a clamping repeatability accuracy of ≤±0.05mm.

[0069] Example 3: The difference from Example 2 is that;

[0070] See attached document Figures 4 to 6Both ends of the rod 72 are fixedly connected to eccentric wheels 64, and both support frames are slidably connected to transmission rods 65 in a vertical sliding manner. The bottom ends of the two transmission rods 65 are in contact with the tops of the two transmission frames 62 respectively, and are used to drive the transmission rods 65 downward by rotating the eccentric wheels 64, so as to form the transmission frame 62 to drive the positioning clamping frame 61 horizontally. Based on embodiment 2, this embodiment adds an eccentric wheel 64 linkage mechanism to realize the coordinated action of the positioning unit 60 and the opening and closing unit 70, and improve the integrated control level and operation continuity of the equipment.

[0071] The eccentric ends of the two eccentric wheels 64 are on the same reference plane as the spool rod 72; when the spool rod 72 is in a vertical downward state, for opening or closing the lid, the two eccentric wheels 64 drive the two positioning clamps 61 to move in opposite directions, forming a real-time positioning clamp for the reagent kit 40; and when the spool rod 72 is in a horizontal state, for overall defect detection or internal defect detection of the reagent kit 40, the two eccentric wheels 64 lose their relative movement to the two positioning clamps 61, and cooperate with the two sets of spring groups 63 to cause the positioning clamps 61 to retract.

[0072] The eccentric wheel 64 is fixed by connecting the two ends of the multi-shaped rod 72 with a flat key, and its eccentric end is on the same reference plane as the multi-shaped rod 72 to ensure the synchronization of the linkage action. The transmission rod 65 is vertically slidably connected to the two support frames by linear bearings, and its bottom end is in spherical contact with the top of the transmission frame 62 to avoid jamming during the movement.

[0073] When the rod 72 is in a vertically downward state (initial state or closed state), the eccentric end of the eccentric wheel 64 contacts the top of the transmission rod 65 and applies downward pressure, driving the transmission rod 65 to move vertically downward along the linear bearing. The bottom end of the transmission rod 65 presses against the transmission frame 62, causing the transmission frame 62 to slide downward, thereby driving the two positioning clamping frames 61 to move relative to each other, realizing the real-time positioning and clamping of the reagent kit 40. At this time, the clamping force is stable at about 8N, ensuring that the position of the reagent kit 40 is fixed during the opening or closing process and avoiding displacement.

[0074] When the rotary motor 71 drives the spool 72 to rotate to a horizontal position, the eccentric end of the eccentric wheel 64 rotates with the spool 72 and disengages from the transmission rod 65. The transmission rod 65 loses its downward pressure, and the transmission frame 62 loses the squeezing force of the transmission rod 65. The positioning clamping frame 61 retracts under the elastic restoring force of the spring assembly 63 and hides under the anti-deviation baffle frame 13 (ensuring the normal transport of the reagent kit 40). At this time, the industrial camera 50 can perform defect detection on the overall appearance of the reagent kit 40 (when the spool 72 is horizontal and facing upward) or the internal cavity. During the detection process, the reagent kit 40 is only limited by the anti-slip surface of the conveyor belt 11 and the anti-deviation baffle frame 13, ensuring that the detection field of view is unobstructed.

[0075] The eccentric wheel 64 linkage mechanism realizes the mechanical linkage between the positioning unit 60 and the opening and closing unit 70 without the need for additional drive components and control logic, which simplifies the equipment structure and control system, reduces energy consumption and failure risk, and at the same time ensures the precise coordination of positioning, clamping and detection actions, thereby improving the operating efficiency of the equipment.

[0076] The working principle of the visually inspectable reagent delivery device of the present invention is as follows:

[0077] Feeding stage: The test kit 40 to be tested is placed on the conveyor belt 11 manually or by an automated feeding mechanism. The test kit 40 is conveyed along the central axis of the conveyor belt 11 under the limiting action of the anti-deviation baffle frame 13. The speed-regulating motor controls the conveying speed according to preset parameters. Visual inspection of the appearance defects of the conveyed test kit 40 can be performed directly by the industrial camera 50.

[0078] Equidistant Stop: When the reagent kit 40 moves to the preset station of the visual inspection module, the photoelectric sensor detects the reagent kit 40 and sends a signal to the controller. The controller triggers the stop cylinder 12 to extend, and the stop plate blocks the reagent kit 40 to stop, ensuring that the reagent kit 40 is in the center of the detection position.

[0079] Positioning and clamping: After stopping, the rotary motor 71 drives the rod 72 to rotate to a vertically downward state. The eccentric wheel 64, in conjunction with the transmission rod 65 and the transmission frame 62, drives the positioning and clamping frame 61 to move relative to each other, thereby achieving the positioning, clamping and centering calibration of the reagent kit 40.

[0080] Opening detection: After positioning, the external air pump introduces compressed air into the L-shaped rod 722 through the air pressure connector, driving the U-shaped rod 721 to extend and make the negative pressure nozzle 73 contact the lid of the reagent kit 40; then the external negative pressure pump starts, and the negative pressure nozzle 73 generates negative pressure to adsorb and fix the lid; the rotary motor 71 drives the U-shaped rod 72 to rotate to a horizontal downward position, causing the lid to flip 180°, and the interior of the reagent kit 40 is fully exposed; the industrial camera 50 starts image acquisition to detect the internal cavity, and the detection data is transmitted to the controller for analysis in real time.

[0081] Closing and Appearance Inspection: After the internal inspection is completed, the rotary motor 71 drives the U-shaped rod 72 to rotate 180° in the opposite direction, and the lid is reset to the top of the box body; the air pump reverses the air supply, the U-shaped rod 721 retracts, and the lid fits into the box body; the negative pressure pump stops working, and the negative pressure nozzle 73 releases the lid; the U-shaped rod 72 continues to rotate to the horizontal upward position, and the positioning clamp 61 retracts and hides; the industrial camera 50 performs defect inspection on the overall appearance of the reagent kit 40.

[0082] Sorting and Packaging: After the test is completed, the controller issues an instruction based on the test result. If it is a defective product, the sorting module 20 will remove the defective reagent kit 40 to the waste collection box; if it is a qualified product, the reagent kit 40 will be directly transported to the film packaging module 30 by the conveyor belt 11 to complete the heat shrink film packaging. The packaged qualified product will be output to the unloading station by the conveyor belt 11.
