Description

Technical Field

[0001] This invention relates to the field of medical rapid diagnosis product packaging technology, and in particular to a laser-coded packaging production line for irregularly shaped plates and its process. Background Technology

[0002] Medical rapid diagnostic products are used to quickly diagnose whether a sample contains the analyte. They are widely used in hospitals or at home. These medical rapid diagnostic products include reagent strips, pipettes, desiccants, and packaging bags. To prevent impurities from entering, the reagent strips and pipettes need to be packaged in bags after production to ensure the accuracy of subsequent test results.

[0003] Before being packaged, reagent plates need to be laser-coded. Different characters correspond to different positions on the reagent plate so that the tester can understand the test items and results later. Ordinary coding machines require manual loading and unloading, have low coding efficiency, and may contaminate the reagent plates in the process. They are mostly designed for one type of reagent plate and have poor applicability.

[0004] To improve packaging efficiency, multiple workstations often package together. The size of the packaging bag is different from that of the reagent plate. In the actual packaging process, how to adjust the product discharge distance inside the packaging bag is also a technical problem that needs to be solved. How to make the feeding distance of the products (reagent plate, pipette, desiccant) inside the packaging bag consistent with the inlet distance of the packaging bag.

[0005] The desiccant involves both a long side and a short side. Only when the short side of the desiccant is aligned with the inlet of the packaging bag can the desiccant be smoothly pushed into the packaging bag. Otherwise, the long side may be too long and affect the insertion into the bag. After the bag is filled, the packaging bag needs to be sealed. If the product is not filled into the bag properly and is located at the sealing point of the packaging bag, directly heat-sealing the packaging bag will cause air leakage. If the seal is not in place, the imperfect seal will allow impurities to easily enter the packaging bag.

[0006] Based on the above defects and shortcomings, it is necessary to improve the existing technology and design a laser marking packaging production line for irregularly shaped plates and its process. Summary of the Invention

[0007] The main technical problem solved by this invention is to provide a laser-marked packaging production line for irregularly shaped plates and its process, which integrates laser marking, reagent plates, pipettes, desiccants, packaging bag feeding, bag opening, bag filling, heat sealing and sorting unloading into one integrated system.

[0017] A process for laser marking and packaging production line for irregularly shaped plates includes the following steps: S1. Reagent plate coding, including the following steps: S1.1 Reagent boards are loaded. The reagent boards are conveyed by a fixed-distance conveyor line. The loading robot picks up and transports the reagent boards on the fixed-distance conveyor line to the quick-change fixture on the turntable. S1.2 Laser marking: The turntable is driven to rotate by the cam divider. The quick-change tooling is rotated to the laser marking station. The laser marking device marks the reagent plate. The dust extraction pipe is used to extract dust through the negative pressure equipment to remove the smoke and dust generated during the laser marking process. S1.3 Inspection: Quick change tooling to inspection station, visual inspection device CCD camera visual inspection and coding; S1.4. Classify and unload materials. Quick change tooling to unload station. Unload robot grabs the defective products and places them on receiving chute. Defective products slide to defective product flow channel for output. Unload robot grabs the qualified products and places them on reagent plate conveyor. S2. Reagent plates are fed at a fixed distance. After being coded, the reagent plates are conveyed along the reagent plate conveyor line. The spacing of the guide plates of the limiting component is pre-adjusted to be consistent with the length of the reagent plate. The reagent plates enter the limiting component of the reagent plate conveyor line. The pushing component pushes one or more reagent plates to the receiving platform in sequence. The pressing component elastically presses down on the reagent plates. The conveying linear module of the fixed distance transport component drives the suction nozzle to lift and adsorb the reagent plates in sequence. During this process, the limiting component limits the reagent plates in the front and back directions to prevent them from tilting forward and backward. The pressing component elastically pre-presses the reagent plates to prevent them from tilting left and right, ensuring the picking posture and realizing the fixed distance transport of two reagent plates for subsequent unified picking and feeding. S3. Straw feeding: The straws in the vibratory feeder are hung and output along the straight vibratory feeder. The two straw flat clamp cylinders of the flipping and conveying component clamp the straw heads. The piston rod of the flipping cylinder extends and drives the rotating rod to a horizontal state, placing the straws horizontally on the straw carrier. The straw conveying line outputs the straws at equal distances. The dual-station straw handling robot grabs the two straws and places them at the straw flat clamp cylinder. The transfer linear module drives the transfer plate to extend, and the two straws move to the side of the reagent plate in the step. S4. Packaging bag feeding: The switching cylinder of the packaging bag feeding mechanism drives the packaging bag hopper to switch to the top of the lifting module. The lifting module lifts the packaging bags in the packaging bag hopper to the top in sequence. The upper and lower cylinders of the bag pressing and positioning mechanism drive the upper and lower plates to move down. When the sensor senses the lifted packaging bag, the bag handling and opening mechanism drives the handling component to absorb the upper packaging bag and place it on the packaging bag positioning carrier. The bag handling and opening mechanism drives the bag opening and handling component to absorb the packaging bag positioning carrier onto the main conveyor. S5. When the packaging bag is opened, the suction cups at the bottom opening module and the bag opening and conveying component simultaneously adhere to the top and bottom sides of the packaging bag. The bag opening and conveying component moves upward, and the packaging bag opening is opened. S6. Desiccant feeding: The desiccant feeder tape on the desiccant feeding tray is conveyed along the conveying and cutting mechanism. The feeding component drives the tape to convey the desiccant. During the conveying process, the anti-retraction brush can be lifted elastically. When the desiccant is being cut, the anti-retraction brush is pressed down by the spring force to prevent the desiccant from being pushed back. The front desiccant is conveyed to the desiccant carrier. The cutting component cuts the desiccant off the tape. The rotating component of the rotating feeding mechanism picks up the desiccant. The feeding linear module and the rotating module work together to move the desiccant to the bag inlet mechanism of the intermediate bagging docking device. S7. Bag entry: The gripper conveying mechanism simultaneously adsorbs and transports the reagent plate and the pipette at step S to the bag entry mechanism. At this time, the desiccant, reagent plate and pipette are all located on the collection plate. The first linear module drives the front end of the collection plate to insert into the opening of the packaging bag, and the second linear module drives the feeding push plate to move, pushing the product on the collection plate into the packaging bag. S8. Heat sealing: The packaging bag containing the product is conveyed along the main conveyor line. The anti-jump belt on the anti-jump bag assembly is placed above the packaging bag to prevent the packaging bag from jumping out of the conveyor line during the conveying process. The elastic pressure plate of the bag pressing and exhaust assembly pre-presses the packaging bag to expel excess gas in the packaging bag before heat sealing, so as to avoid the packaging bag from bulging during heat sealing. The packaging bag is moved to the heat sealing mechanism. The elastic pre-pressing assembly is driven by a bidirectional cylinder to pre-press the sealing point of the packaging bag. When the pre-pressing plate pre-presses the product inside the packaging bag, the bidirectional cylinder cannot press it in place. The cylinder alarms through the sensor to identify the defective product. When the pre-pressing plate is in place, the heat sealing module is driven by a bidirectional cylinder to move relative to the product. The heat sealing module heats and heat seals the packaging bag by thermocouples to seal the packaging bag. The two heat sealing mechanisms are a group, and the heat sealing packaging has a two-stage heat sealing effect. S9. Unloading: The unloading robot grabs qualified heat-sealed products and places them on the finished product conveyor line for output. It grabs unqualified heat-sealed products and places them in the defective product box.

[0018] Compared with the prior art, the beneficial effects of the present invention are: The quick-change tooling has pre-reserved grooves for various types of reagent plates, allowing for the selection of the first or second tooling plate according to actual application needs, enabling quick positioning and installation, and has wide applicability. The laser marking device can mark reagent plates, the visual inspection device can quickly detect the marking effect, and the unloading device can automatically classify them. The reagent plate conveying device outputs two reagent plates at a fixed distance, ensuring that the distance between them is consistent with the subsequent packaging bags, and preventing them from tilting forward, backward, left, or right during the output process, thus guaranteeing their output posture. The straw feeding and handling device uses a flipping and handling component to horizontally and at a fixed distance transport vertically hung straws to a fixed-distance horizontal conveyor line. The straws are then finally transported to the side of the reagent plate by a dual-station straw handling robot and a straw transfer mechanism to ensure their relative position and prepare for subsequent handling and bagging. The packaging bag feeding device automatically absorbs and transports the packaging bags in the hopper to the main conveyor, which can open the bags and prevents them from jumping out during the conveying process. The desiccant cutting and feeding device automatically conveys and cuts the desiccant. The material picking and rotating component is adjusted according to the actual direction of the desiccant and rotates to transport the desiccant so that its short side is aligned with the opening of the packaging bag for easy bag insertion. The bag feeding mechanism is opposite to the opening of the packaging bag on the main conveyor, which can push the reagent plate, pipette and desiccant into the packaging bag in one go to complete the bagging action. The heat sealing device is equipped with a bag-pressing and degassing component that can pre-press out excess gas inside the packaging bag. The heat sealing mechanism is arranged in pairs to ensure the heat sealing effect at the entrance of the packaging bag. The elastic pre-pressing component can detect whether there is a product at the entrance in time and detect unqualified products, so as to prepare for the subsequent rejection of defective products.

[0047] A process for laser marking and packaging production line for irregularly shaped plates includes the following steps: S1. Reagent plate coding, including the following steps: S1.1 Reagent boards are loaded. The reagent boards are conveyed by the fixed-distance conveyor line 131. The loading robot 132 picks up and transports the reagent boards on the fixed-distance conveyor line 131 to the quick-change tooling 12 on the turntable 11. S1.2 Laser marking: Turntable 11 is driven to rotate by cam divider, quick change fixture 12 rotates to laser marking station, laser marking machine 142 marks the reagent plate, dust extraction pipe 144 extracts dust through negative pressure equipment to remove the smoke and dust generated during laser marking. S1.3 Inspection: Quick change tool 12 is transferred to the inspection station, and the CCD camera inspection module of the vision inspection device 15 performs visual inspection and coding. S1.4. Classify and unload materials. Quick change tooling 12 is transferred to the unloading station. Unloading robot 161 grabs the unqualified products and places them on the receiving chute 162. The unqualified products slide to the defective product flow channel conveyor line 163 for output. Unloading robot 161 grabs the qualified products and places them on the reagent plate conveyor device 2. S2. Reagent plates are fed at a fixed distance. After being coded, the reagent plates are conveyed along the reagent plate conveyor line 21. The spacing of the guide plates 232 of the limiting component 23 is pre-adjusted to be consistent with the length of the reagent plate. The reagent plates enter the limiting component 23 along the reagent plate conveyor line 21. The pushing component 24 pushes one or more reagent plates to the receiving platform 22 in sequence. The pressing component 25 elastically presses down on the reagent plates. The conveying linear module 261 of the fixed distance conveying component 26 drives the suction nozzle 263 to lift and adsorb the reagent plates in sequence. During this process, the limiting component 23 limits the reagent plates in the front and back directions to prevent them from tilting forward and backward. The pressing component 25 elastically pre-presses the reagent plates to prevent them from tilting left and right, ensuring the picking posture and realizing the fixed distance conveying of two reagent plates for subsequent unified picking and feeding. S3. Straw feeding: The straws in the vibratory feeder 31 are hung and output along the linear vibratory feeder 32. The two straw flat clamp cylinders 335 of the flipping and conveying assembly 33 clamp the straw heads. The piston rod of the flipping cylinder 333 extends and drives the rotating rod 332 to a horizontal state, placing the straws horizontally on the straw carrier 342. The straw conveying line 341 outputs the straws at equal distances. The dual-station straw handling robot 35 grabs the two straws and places them at the straw flat clamp cylinder 363. The transfer linear module 361 drives the transfer plate 362 to extend, and the two straws move to the side of the reagent plate in step 2. S4. Packaging bag feeding: The switching cylinder 413 of the packaging bag feeding mechanism 41 drives the packaging bag hopper 412 to switch to the top of the lifting module 42. The lifting module 42 lifts the packaging bags in the packaging bag hopper 412 to the top in sequence. The upper and lower cylinders 432 of the bag pressing and positioning mechanism 43 drive the upper and lower plates 433 to move down. When the sensor senses the lifted packaging bag, the bag handling and opening mechanism 44 drives the handling component 444 to absorb the upper packaging bag and place it on the packaging bag positioning carrier 434. The bag handling and opening mechanism 44 drives the bag opening and handling component 445 to absorb the packaging bag positioning carrier 434 onto the main line conveyor 5. S5. When the packaging bag is opened, the suction cups at the lower opening module 52 and the opening and conveying component 445 simultaneously adhere to the upper and lower sides of the packaging bag. The opening and conveying component 445 moves upward and the opening of the packaging bag is opened. S6. Desiccant feeding: The desiccant material belt on the desiccant feeding tray 61 is conveyed along the conveying and cutting mechanism 62. The feeding component 622 drives the material belt to convey. During the conveying process, the anti-retraction brush 6233 can be elastically lifted. When the desiccant is being cut, the anti-retraction brush 6233 presses down on the desiccant under the action of the spring force to prevent material retraction. The front desiccant is conveyed to the desiccant carrier 6241. The cutting component 624 cuts the desiccant off the material belt. The picking and rotating component 637 of the rotating feeding mechanism 63 adsorbs the desiccant. The feeding linear module 632 and the rotating module 634 work together to move the desiccant to the bag inlet mechanism 71 of the intermediate bag docking device 7. S7. Bag entry: The gripper conveying mechanism 72 simultaneously adsorbs and transports the reagent plate from step S2 and the pipette from step S3 to the bag entry mechanism 71. At this time, the desiccant, reagent plate and pipette are all located on the collection plate 713. The first linear module 712 drives the front end of the collection plate 713 to insert into the opening of the packaging bag. The second linear module 714 drives the feeding push plate 715 to move and push the product on the collection plate 713 into the packaging bag. S8. Heat sealing: The packaging bag containing the product is conveyed along the main conveyor line 51. The anti-jump belt 534 on the anti-jump bag assembly 53 is placed above the packaging bag to prevent the packaging bag from jumping out of the conveyor line during the conveying process. The elastic pressure plate 844 of the bag pressing and exhaust assembly 84 pre-presses the packaging bag to expel excess gas in the packaging bag before heat sealing, so as to avoid the packaging bag from bulging during heat sealing. The packaging bag is moved to the heat sealing mechanism 82. The elastic pre-pressing assembly 83 is driven by the bidirectional cylinder 822 to pre-press the sealing point of the packaging bag. When the pre-pressing plate 832 pre-presses the product inside the packaging bag, the bidirectional cylinder 822 cannot press it in place. The cylinder alarms through the sensor and identifies the defective product. When the pre-pressing plate 832 pre-presses in place, the heat sealing module 824 is driven by the bidirectional cylinder 822 to move relative to it. The heat sealing module 824 heats and heat seals the packaging bag by thermocouples to seal the packaging bag. The two heat sealing mechanisms 82 are a group, and the heat sealing effect of the packaging is achieved by two heat sealing processes. S9. Unloading: The unloading robot 91 picks up qualified heat-sealed products and places them on the finished product conveyor line 93 for output. It picks up unqualified heat-sealed products and places them in the defective product box 92.

The reagent plates are fed at a fixed distance. After being coded, the reagent plates are conveyed along the reagent plate conveyor line (21). The spacing of the guide plates (232) of the limiting component (23) is pre-adjusted to be consistent with the length of the reagent plate. The reagent plates enter the limiting component (23) of the reagent plate conveyor line (21). The pushing component (24) pushes one or more reagent plates to the receiving platform (22) in sequence. The pressing component (25) elastically presses down on the reagent plates. The conveying linear module (261) of the fixed distance conveying component (26) drives the suction nozzle (263) to lift and adsorb the reagent plates in sequence. During this process, the limiting component (23) limits the reagent plates in the front and back directions to prevent them from tilting forward and backward. The pressing component (25) elastically pre-presses the reagent plates to prevent them from tilting left and right, ensuring the picking posture and realizing the fixed distance conveying of the two reagent plates so that they can be picked up and fed in a unified manner later. S3. The straws are fed into the vibratory feeder (31) and the straws are hung and output along the straight vibratory feeder (32). The two straw flat clamp cylinders (335) of the flipping and handling assembly (33) clamp the straw heads. The piston rod of the flipping cylinder (333) extends and drives the rotating rod (332) to rotate to a horizontal state, and the straws are placed horizontally on the straw carrier (342). The straw conveyor line (341) outputs the straws at equal distances. The dual-station straw handling robot (35) grabs the two straws and places them at the straw flat clamp cylinder (363). The transfer linear module (361) drives the transfer plate (362) to extend, and the two straws are moved to the side of the reagent plate in step 2. S4. Packaging bag feeding: The switching cylinder (413) of the packaging bag feeding mechanism (41) drives the packaging bag hopper (412) to switch to the top of the lifting module (42). The lifting module (42) lifts the packaging bags in the packaging bag hopper (412) to the top in sequence. The upper and lower cylinders (432) of the bag pressing and positioning mechanism (43) drive the upper and lower plates (433) to move down. When the sensor senses the lifted packaging bag, the bag handling and opening mechanism (44) drives the handling component (444) to adsorb the upper packaging bag and place it on the packaging bag positioning carrier (434). The bag handling and opening mechanism (44) drives the bag opening and handling component (445) to adsorb the packaging bag positioning carrier (434) onto the main line conveyor (5). S5. When the packaging bag is opened, the suction cups at the lower opening module (52) and the bag opening and conveying component (445) simultaneously adsorb the upper and lower sides of the packaging bag. The bag opening and conveying component (445) moves upward and the packaging bag opening is opened. S6. Desiccant feeding: The desiccant material belt on the desiccant feeding tray (61) is conveyed along the conveying and cutting mechanism (62). The feeding component (622) drives the material belt to be conveyed. During the conveying process, the anti-retraction brush (6233) can be elastically lifted. When the desiccant is being cut, the anti-retraction brush (6233) presses down on the desiccant under the action of the spring force to prevent material retraction. The front desiccant is conveyed to the desiccant carrier (6241). The cutting component (624) cuts the desiccant off the material belt. The material picking and rotating component (637) of the rotating feeding mechanism (63) adsorbs the desiccant. The feeding linear module (632) and the rotating module (634) work together to move the desiccant to the bag feeding mechanism (71) of the intermediate bag docking device (7). S7. Bag entry: The gripper transport mechanism (72) simultaneously adsorbs and transports the reagent plate at step S2 and the pipette at step S3 to the bag entry mechanism (71). At this time, the desiccant, reagent plate and pipette are all located on the collection plate (713). The first linear module (712) drives the front end of the collection plate (713) to insert into the opening of the packaging bag. The second linear module (714) drives the feeding push plate (715) to move, pushing the product on the collection plate (713) into the packaging bag. S8. Heat sealing: The packaging bag containing the product is conveyed along the main conveyor line (51). The anti-jump belt (534) on the anti-jump bag assembly (53) is placed above the packaging bag to prevent the packaging bag from jumping out of the conveyor line during the conveying process. The elastic pressure plate (844) of the bag pressing and venting assembly (84) pre-presses the packaging bag to expel excess gas in the packaging bag before heat sealing, so as to avoid the packaging bag from bulging during heat sealing. The packaging bag is moved to the heat sealing mechanism (82). The elastic pre-pressing assembly (83) is driven by the bidirectional cylinder (822). At the pre-pressed packaging bag sealing point, when the pre-press plate (832) presses the product inside the packaging bag, the bidirectional cylinder (822) cannot press it into place. The cylinder alarms through the sensor and identifies the defective product. When the pre-press plate (832) presses it into place, the heat sealing module (824) is driven by the bidirectional cylinder (822) to move relative to the product. The heat sealing module (824) heats and heat seals the packaging bag by thermocouples to seal the packaging bag. The two heat sealing mechanisms (82) are a group, and the heat sealing packaging heat pressing effect is achieved twice. S9. Unloading: The unloading robot (91) picks up qualified heat-sealed products and places them on the finished product conveyor line (93) for output. It picks up unqualified heat-sealed products and places them in the defective product box (92).
