Description

Technical Field

[0001] This utility model relates to the field of automated manufacturing, and specifically discloses a reagent bag dispensing mechanism. Background Technology

[0002] The reagent bag dispensing mechanism is a key automated piece of equipment in modern medical testing and biopharmaceutical production, primarily used for continuous operations in scenarios such as in vitro diagnostic reagents and drug packaging. This mechanism typically includes a bag storage unit, a conveying module, a testing station, and sorting execution components. The testing module identifies the sealing status of the reagent bags, accurately distinguishing between qualified and defective products (primarily based on whether they are unsealed). The sorting system directs qualified products to the finished product collection area, while defective products are transferred to a dedicated collection device for temporary storage. Existing technologies have achieved automated sorting and classification collection during the dispensing process, meeting the core requirement of efficient reagent bag dispensing for basic production lines. With the increasingly stringent requirements for aseptic operation in the biopharmaceutical industry, improving the protection and continuity of defective product storage has become an important direction for technological evolution.

[0003] Existing devices only address the issues of manual bag opening during the manual packaging of antigen test kits and desiccants, which is labor-intensive and inefficient. While they optimize the bagging process, they do not cover defective product protection. In practical applications of the reagent bag discharging mechanism, although the detection module can identify the packaging status of the reagent bags and the sorting system can transport qualified and defective products to different collection areas, unsealed reagent bags still require manual removal after the collection frame is full. During this process, hand contact with the bag opening poses a potential risk of contaminating the contents. Furthermore, traditional collection frames are mostly open structures, making it easy for external dust or microorganisms to enter the reagent bags through the unsealed openings, further exacerbating the contamination risk. In addition, manual intervention limits the processing speed of defective products, making it difficult to synchronize with the pace of high-speed automated production lines, potentially leading to production line congestion or defective product backlog. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a reagent bag dispensing mechanism to solve the technical problem that the reagent bag dispensing mechanism cannot automatically replace the defective product collection box.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a reagent bag discharging mechanism, including a base plate, on which a conveying device for conveying pre-sealed reagent bags is provided; a sorting device for sorting defective and qualified products is provided on the conveying device; a defective product conveying frame located within the travel trajectory of the sorting device is fixedly connected to the conveying device; a qualified product collection mechanism is provided on the base plate, located below the travel trajectory of the sorting device; and a defective product collection and transfer mechanism is provided on the base plate for uniformly collecting defective reagent bags.

[0006] In this solution, the defective product collection and transportation mechanism can automatically collect defective reagent bags, reducing manual intervention, lowering the risk of contamination, and improving production efficiency.

[0007] Furthermore, the defective product collection and transfer mechanism includes a fixed frame, which is fixedly connected to the base plate. The fixed frame has an inlet and an outlet. A collection frame is slidably arranged inside the fixed frame. The collection frame has an installation port. A movable frame is fixedly connected to the installation port. Two springs are arranged inside the movable frame. One end of each spring is fixedly connected to the inside of the movable frame. The other end of each spring is fixedly connected to a movable plate. The movable plate is slidably connected to the movable frame. A first limiting block is fixedly connected to the movable plate. The collection frame has a discharge port that penetrates the inner and outer walls. A detachable cover plate is installed at the discharge port. A first hydraulic rod is arranged on the base plate. The telescopic end of the first hydraulic rod contacts and cooperates with the collection frame. A limiting device for limiting the first limiting block is arranged on the defective product conveying frame. A temporary storage device for temporarily storing defective reagents is arranged on the defective product conveying frame. A positioning structure for preventing displacement of the collection frame is arranged on the collection frame.

[0008] In this solution, as the first hydraulic rod pushes the collection frame to move below the defective product conveying frame, the second limiting block contacts and engages with the first limiting block, forcing the moving plate to compress the spring and slide into the moving frame, automatically opening the installation port. After filling is completed, the spring automatically resets and pushes the moving plate to close the installation port. The entire process requires no manual intervention, effectively reducing the risk of secondary reagent contamination that may be caused by manual operation. This not only improves the efficiency of defective product collection but also significantly enhances the hygiene and safety of the collection process.

[0009] Furthermore, the collection frame also includes an observation plate, an observation port is opened on the collection frame, and an observation plate is installed at the observation port.

[0010] In this solution, operators can monitor the stacking height, leakage status, and signs of contamination of defective reagent bags in real time, intuitively grasp the collection of defective products, and reduce the risk of microbial intrusion caused by opening the caps for testing.

[0011] Furthermore, the limiting device includes a second hydraulic rod, which is installed on the defective product conveying frame, and the telescopic end of the second hydraulic rod is fixedly connected to a second limiting block that can contact and cooperate with the first limiting block.

[0012] In this solution, when the second hydraulic rod drives the second limiting block to disengage from the first limiting block, the compressed spring automatically releases its potential energy to push the moving plate to reset and close the installation port. After filling is completed, the channel is quickly closed, completely blocking the risk of environmental pollution during subsequent transportation.

[0013] Furthermore, the temporary storage device includes a motor, which is mounted on the defective product conveying frame. A first rotating shaft is rotatably connected to the defective product conveying frame. One end of the first rotating shaft is rotatably connected to the defective product conveying frame, and the other end of the first rotating shaft is fixedly connected to the power output shaft of the motor. A baffle is installed on the first rotating shaft.

[0014] In this solution, the temporary storage device uses a motor-driven baffle to flip, which can temporarily store defective products that fall into the defective product conveying frame. When replacing the collection frame, there is no need to stop the operation of the discharge mechanism, which effectively avoids production interruption caused by replacing the collection frame and improves production efficiency.

[0015] Furthermore, the positioning structure includes a second rotating shaft, an installation groove is provided below the collection frame, the second rotating shaft is fixedly connected in the installation groove, a ratchet mechanism is fixedly connected on the second rotating shaft, a gear is sleeved on the ratchet mechanism, and the gear meshes with multiple racks provided on the fixed frame for transmission.

[0016] In this solution, the problem of accidental closure of the installation port caused by the elastic restoring force of the spring is solved by the positioning structure. When the collection frame moves towards the inlet under the spring's restoring force, the rack and pinion drive gear rotates clockwise, and the ratchet mechanism locks the second rotating shaft to form a rigid lock, completely blocking the displacement. When moving in the forward direction, the gear rotates freely counterclockwise, realizing unidirectional motion control.

[0017] The working principle and beneficial effects of this solution are as follows:

[0018] The conveying device delivers reagent bags to the testing device for sorting. Qualified products enter the qualified product collection mechanism, while defective products fall into the defective product conveying frame. The motor drives the baffle to rotate 90 degrees to temporarily store defective products. During this process, the collection frame is manually pushed into the fixed frame. When the first hydraulic rod pushes the collection frame to move, the second hydraulic rod drives the second limit block to limit the first limit block, causing the moving plate to compress the spring and open the mounting port. At the same time, the gear and rack mesh and rotate counterclockwise. After the collection frame aligns with the defective product conveying frame, the baffle is released, and the defective products fall into the collection frame. After the first hydraulic rod resets, it pushes a new collection frame in. The ratchet mechanism locks to prevent displacement. After the observation plate monitors the full load, the baffle closes the conveying frame. The second hydraulic rod drives the second limit block to release the limit on the first limit block. The spring pushes the moving plate to close the mounting port. The first hydraulic rod pushes the new collection frame to replace the full-load frame and move it out of the outlet. This achieves the technical problem of automatically replacing the defective product collection frame and eliminates the risk of manual contamination.

[0036] like Figure 2 As shown, the defective product collection and transfer mechanism also includes a first inclined platform 27 and a second inclined platform 28. An inlet 29 is provided on the fixed frame 2, and the inlet 29 extends into the fixed frame 2. The inlet 29 is located on the side close to the first hydraulic rod 10. The first inclined platform 27 is provided at the inlet 29 and is fixedly connected to the fixed frame 2. An outlet 30 is provided on the fixed frame 2, and the outlet 30 extends into the fixed frame 2. The outlet 30 is located on the side away from the inlet 29. The second inclined platform 28 is provided at the outlet 30 and is fixedly connected to the fixed frame 2.

[0037] In practice

[0038] The conveying device on the base plate 31 transports the sealed reagent bags to the testing device for testing. The testing device tests the reagent bags and then sorts the defective reagent bags from the qualified reagent bags through the sorting device. The qualified reagent bags are sorted into the qualified product collection mechanism for unified collection, while the defective reagent bags are sorted into the defective product conveying frame 1 and transported into the defective product conveying frame 1. At this time, the motor 19 on the third fixed frame 18 drives the first rotating shaft 20 to rotate. The first rotating shaft 20 drives the baffle 21 to rotate 90 degrees in the defective product conveying frame 1, temporarily sealing the defective product conveying frame 1. At this time, the defective reagent bags will be temporarily stored in the defective product conveying frame 1. During this period, the collection frame 3 is manually pushed to slide along the first inclined platform 27, so that it enters the interior of the fixed frame 2 through the inlet 29 of the fixed frame 2.

[0039] After the collecting frame 3 enters the fixed frame 2, the first hydraulic rod 10 on the first fixed frame 9 is activated. The telescopic end of the first hydraulic rod 10 pushes the collecting frame 3 to move closer to the outlet 30 within the fixed frame 2. During the movement of the collecting frame 3, the first limiting block 7 on the moving plate 6 contacts the second limiting block 17 on the second hydraulic rod 16. The second limiting block 17 limits and fixes the first limiting block 7. At this time, the collecting frame 3 is in a moving state. The collecting frame 3 continues to move closer to the outlet 30. The first limiting block 7 is limited by the second limiting block 17 and is relatively stationary. At this time, the first limiting block 7 will drive the moving plate 6 to gradually move into the moving frame 4. During the movement, the moving plate 6 will gradually compress the spring 5 inside the moving frame 4 to store elastic potential energy for the subsequent reset of the moving plate 6.

[0040] As the moving plate 6 gradually enters the moving frame 4, the gear 25 in the mounting groove 26 below the collection frame 3 will gradually mesh with the rack 24 on the fixed frame 2. When the collection frame 3 moves towards the outlet 30, the gear 25 drives the ratchet mechanism 23 to rotate counterclockwise. At this time, the gear 25 can rotate normally through the ratchet mechanism 23. When the extension stroke of the first hydraulic rod 10 reaches its maximum, the collection frame 3 is completely aligned with the bottom of the defective product conveying frame 1. Since the moving plate 6 is pushed into the moving frame 4, the mounting port 11, which was previously blocked by the moving plate 6, will connect with the defective product conveying frame 1. At this time, the motor 19 can be driven to rotate the shaft again by ninety degrees. The defective reagent bag temporarily stored in the defective product conveying frame 1 will fall into the collection frame 3 through the mounting port 11 for collection. The extension end of the first hydraulic rod 10 moves back to the initial position.

[0041] After the first hydraulic rod 10 moves back to its initial position, the next collection box 3 can be directly pushed into the fixed box 2, so that it can continuously collect and process defective reagent bags. At this time, the collection box 3 located below the defective product conveying box 1 is always in the process of collecting defective products. When the installation port 11 is opened, it is achieved by pushing the moving plate 6 into the moving box 4. At this time, the spring 5 stores elastic potential energy to provide power for subsequent reset. At this time, the collection box 3 will be pushed towards the side closer to the inlet 29 by the spring 5 storing elastic potential energy, which will cause the installation port 11 to be closed. When the collection box 3 is pushed towards the side closer to the inlet 29 by external force, the rack 24 drives the gear 25 to rotate clockwise. Since the second rotating shaft 22 on the ratchet mechanism 23 is fixedly connected to the collection box 3, when the gear 25 rotates clockwise, it drives the ratchet mechanism 23 to rotate clockwise as a whole. This second rotating shaft 22 is in a fixed state. At this time, the gear 25 is restricted from rotating clockwise and also restricts the collection box 3 from moving towards the side closer to the inlet 29.

[0042] The filling status inside the collection frame 3 is observed through the observation plate 13. When the collection frame 3 is full of defective products, the motor 19 is first started to rotate, driving the baffle 21 to rotate 90 degrees to block the defective product conveying frame 1. Then, the second hydraulic rod 16 on the second fixed frame 15 drives the second limiting block 17 to move away from the first limiting block 7. At this time, the first limiting block 7 is stopped, and the compressed spring 5 pushes the moving plate 6 out of the moving frame 4. The moving plate 6 blocks the installation port 11. The first hydraulic rod 10 is started. Since the next collection frame 3 to be filled has been pushed into the fixed frame 2, the extension end of the first hydraulic rod 10 pushes the second collection frame 3 to be filled. When filling the collection box 3, the second collection box 3 pushes the already filled collection box 3. When the second hydraulic rod 16 drives the second limit block 17 to rise to the preset end point of the stroke, the second hydraulic rod 16 drives the second limit block 17 to fall and reset to the initial position. When the installation port 11 of the second collection box 3 is connected to the defective product conveying box 1, the previously filled collection box 3 is pushed to the outlet 30. At this time, the collection box 3 can be pulled out from the outlet 30 directly through the second inclined platform 28. After the cover plate 8 on the collection box 3 is removed, the defective products in the collection box 3 can be poured out from the discharge port 12, and then the defective products can be recycled and processed again.

[0043] The above description is merely an embodiment of this utility model, and common knowledge such as specific structures and characteristics in the solution is not described in detail here. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of this utility model, and these should also be considered within the protection scope of this utility model. These modifications and improvements will not affect the effectiveness of the implementation of this utility model or its practicality.
