Description

Technical Field

[0001] This invention relates to the field of medical assembly technology, and more particularly to a dual-channel reagent kit combination packaging device and method. Background Technology

[0002] In the production of medical and biotechnology products such as in vitro diagnostic reagents and biochips, finished reagent kits typically need to be sealed in aluminum foil bags along with desiccants to ensure their stability and effectiveness during transportation and storage. With increasing production capacity demands, the use of dual-channel fully automated bagging machines for high-speed, parallel packaging has become industry mainstream. This type of equipment can process two lines of material simultaneously, significantly improving packaging efficiency, but it also places more stringent demands on the continuity and reliability of equipment operation.

[0003] Currently, common dual-channel automatic bagging machines in the aluminum foil bag supply and opening stages mostly use vacuum suction cups to directly pick up the topmost bag in the bag magazine, and use the opposing suction cups to complete the bag opening through mechanical actions of adsorption and separation. However, due to their thin and smooth surface, aluminum foil bags are prone to sticking together tightly when stacked due to electrostatic adsorption and surface vacuum adsorption effects. Existing technical solutions often focus on fault detection and alarms when dealing with this problem, such as using vacuum sensors to determine whether a single bag has been successfully picked up, or using delay detection to determine whether the bag opening is fully open. Once a bag picking failure or incomplete opening is detected, the equipment will stop and alarm or activate the rejection mechanism. This passive approach, in the high-speed continuous operation of the dual-channel mode, will severely restrict the overall production efficiency and output capacity due to frequent unexpected interruptions, becoming a major technical bottleneck for achieving efficient and stable automated packaging.

[0004] Therefore, it is necessary to improve the existing technology to solve the technical problems of bag removal failure and incomplete bag opening caused by physical adhesion and electrostatic adsorption of aluminum foil bags. Summary of the Invention

[0005] The purpose of this invention is to provide a dual-channel reagent kit combination packaging device and method to solve the above-mentioned technical problems.

[0006] To achieve this objective, the present invention adopts the following technical solution: A dual-channel reagent kit combination packaging method includes the following steps: S1, perform anti-adhesion pretreatment on the stacked aluminum foil bags. The anti-adhesion pretreatment includes micro-vibration, static elimination and layered air blowing, so that the aluminum foil bags at the top of the stack are in a pre-separated state. S2, a bag-taking mechanism with a vibrating adsorption head and a splitting air nozzle is used to extract the pre-separated aluminum foil bag, and the bag opening is pre-opened by spraying airflow into the bag opening through the splitting air nozzle during the extraction process; S3, the bag opening in the pre-opened state is opened a second time by the coordinated bag opening mechanism. In this process, the air nozzle inside the bag is opened to inject airflow into the aluminum foil bag to make the bag expand. The upper and lower suction cups work together to pull open the bag opening and keep the bag opening open to form a feeding channel. In the left and right bag filling channels, the reagent kit and desiccant are loaded into the corresponding aluminum foil bags through the corresponding feeding channels.

[0007] Optionally, the method further includes the following steps before step S3: S201, the reagent kits output from the upstream single channel are sequentially intercepted and separated, and distributed to the left and right conveying channels, so that the left and right conveying channels supply materials at the same pace; During the interception and separation process, single-piece release control is implemented for continuously arriving reagent kits, ensuring that only one reagent kit is allowed to enter the corresponding conveying channel in each cycle. When the reagent kit at the end of the corresponding conveying channel is detected to be in place, a pressing-in action is performed to allow the reagent kit to enter the material trough corresponding to the aluminum foil bag.

[0008] Optionally, before step S3 and after step S201, the method further includes: S202 uses a vibratory feeder to orient and convey the desiccant into individual particles, and buffers and blocks the desiccant during the conveying process to form a continuous feeding queue. S203, after the desiccant that has reached the desiccant pushing position is pushed to a preset height higher than or level with the material trough, a direct pushing operation is performed to allow the desiccant to enter the corresponding material trough; Specifically, after direct push, the desiccant is detected to be in place. If no in place signal is detected, at least one abnormal handling action is triggered, such as shutdown alarm, removal of the mark, or re-push.

[0009] Optionally, step S1 includes: S11, perform micro-vibration treatment on the stacked aluminum foil bags to cause relative slippage of the upper layer of bags in the bag stack, so as to break the surface vacuum adsorption effect between adjacent bags. S12, while or after micro-vibration, perform electrostatic elimination treatment to reduce the electrostatic adsorption effect between the upper bags of the bag stack to below a preset threshold. S13, After static electricity is eliminated, layered air blowing is performed. The layered air blowing is applied to the upper layer of the bag stack in a pulse manner, so that a pre-separation gap is formed between the uppermost aluminum foil bag and the lower aluminum foil bag, which can be stably separated by the bag picking mechanism. The micro-vibration, static elimination, and stratified air blowing are performed in a preset sequence, and the completion of the step is determined by the pre-separation gap reaching a preset gap threshold.

[0010] Optionally, step S3 further includes: S31, after completing the secondary bag opening and forming the feeding channel, perform bag opening status detection on the bag opening area to determine whether there is material obstruction or foreign object interference at the bag opening. S32, during the process of pushing the reagent kit and desiccant into the aluminum foil bag through the feed channel, pressure is applied to the desiccant to limit it so that the desiccant is confined within the preset push path during the push process, and a guide channel is formed on the preset push path to prevent the desiccant from flying up or deviating.

[0011] Optionally, after step S3, the method further includes: S4. After bagging, perform online testing on the materials inside the bag and mark the non-conforming products based on the test results; S5 heat-seals the aluminum foil bags after packaging, automatically rejects unqualified products based on the marking results, and transports qualified products to the palletizing station to complete the packaging.

[0012] Optionally, step S5 includes: S51, Before heat sealing, perform positioning and shaping treatment on the packaged aluminum foil bag to correct the wrinkles or posture deviations of the aluminum foil bag so that the bag opening is in a flat and aligned state; S52 sets the heat sealing temperature control parameters according to the material and size of the aluminum foil bag, and performs closed-loop control of the heating temperature during the heat sealing process, so that the bag opening is softened by heat and the fusion seal is completed under the action of pressure. S53, during the heat sealing and pressing process, simultaneously completes the heat transfer of production date or batch number information.

[0013] The present invention also provides a dual-channel reagent kit combination packaging device, employing the dual-channel reagent kit combination packaging method described above, wherein the reagent kit combination packaging device comprises: frame; An aluminum foil bag storage unit is installed on the frame, and the aluminum foil bag storage unit has a carrying space for carrying multiple stacked aluminum foil bags in the vertical direction; An anti-adhesion processing component is disposed on one side of the aluminum foil bag storage and is arranged correspondingly to the upper layer of aluminum foil bags in the aluminum foil bag storage. A bag-picking assembly is disposed between the aluminum foil bag storage and the bagging station. The bag-picking assembly includes a vibrating suction head and a dispensing air nozzle. A collaborative bag opening assembly is provided at the bagging station. The collaborative bag opening assembly includes an in-bag opening nozzle and suction cups located on the upper and lower sides of the aluminum foil bag opening, respectively. A dual-channel alignment component is disposed on one side of the bagging station. The dual-channel alignment component includes a first material channel and a second material channel arranged side by side. The first material channel and the second material channel are respectively aligned with the opening of the corresponding aluminum foil bag.

[0014] Optionally, in the bag-retrieving assembly: The vibration adsorption head is disposed at the bag-taking end of the bag-taking assembly and is positioned toward the upper layer of aluminum foil bags in the aluminum foil bag storage. The separating air nozzle is located on one side or below the vibrating adsorption head, and the airflow jet direction of the separating air nozzle is towards the opening area of ​​the aluminum foil bag. The adsorption position of the vibrating adsorption head and the air jet landing point of the separating air nozzle are both located on the same side of the aluminum foil bag opening, so as to adsorb and extract the aluminum foil bag opening and separate it by air blowing during the bag removal process.

[0015] Optionally, in the collaborative bag-opening component: The inner opening nozzle is arranged along the opening direction of the aluminum foil bag, and the inner opening nozzle has an air outlet that can extend into the inside of the aluminum foil bag opening. The suction cup includes an upper suction cup and a lower suction cup. The upper suction cup is located on the upper side of the opening of the aluminum foil bag, and the lower suction cup is located on the lower side of the opening of the aluminum foil bag. The bag is equipped with an internal air nozzle, an upper suction cup, and a lower suction cup, which are distributed around the opening of the aluminum foil bag to form a feeding channel for the aluminum foil bag through air blowing inside the bag and suction pulling from the top and bottom.

[0016] Compared with the prior art, the present invention has the following beneficial effects: During operation, the aluminum foil bags stacked in the bag storage are first subjected to micro-vibration, static elimination, and layered air blowing to prevent sticking, creating a pre-separation state between the aluminum foil bags at the top of the stack and those below, reducing the risk of bag sticking due to surface adhesion, electrostatic adsorption, or vacuum adsorption. Subsequently, the bag-retrieving mechanism uses a vibrating adsorption head to adsorb and extract the pre-separated aluminum foil bags, while simultaneously spraying airflow into the bag opening area from a separating air nozzle, causing the bag opening to form a preliminary pre-opened state during the bag-retrieving process. After the aluminum foil bags are transferred to the bagging position, a coordinating bag-opening mechanism performs a secondary opening, where an internal air-expanding nozzle injects airflow into the aluminum foil bag to inflate the bag, and upper and lower suction cups act on the upper and lower sides of the bag opening respectively. The bag opening is opened collaboratively, maintaining a stable opening and forming an infeed channel for material entry. Finally, in the two bagging channels on the left and right, the reagent kit and desiccant are respectively loaded into the corresponding aluminum foil bags through their respective infeed channels, thus completing the dual-channel parallel bagging process for reagent kits and desiccant. This solution achieves pre-opening of the bag opening through the split-opening nozzle during the bag-removal stage, and then completes the secondary opening of the bag through the cooperation of the internal opening nozzle and the upper and lower suction cups. This ensures a continuous connection between the separation, extraction, pre-opening and stable opening of the aluminum foil bag, avoiding the problem of unstable bag opening caused by relying solely on single adsorption or single blowing. Moreover, the two bagging channels on the left and right can complete the loading of the reagent kit and desiccant respectively after the bag opening is stably opened, thus achieving stable opening of the aluminum foil bag and efficient and reliable loading of the reagent kit and desiccant.

Detailed Implementation

[0021] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component positioned centrally in the connection.

[0023] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] Example 1: Combination Figure 1 As shown, where, Figure 1 This is a schematic diagram of the system layout of a dual-channel reagent kit combination packaging device. The present invention provides a dual-channel reagent kit combination packaging method. It should be noted that this dual-channel reagent kit combination packaging method is applied to the combined bagging of reagent kits and desiccants. The reagent kit can be a test reagent cartridge, a test strip cartridge, or other box-shaped material that needs to be packaged together with the desiccant. The method uses an aluminum foil bag as the outer packaging bag and performs bag removal, bag opening, and bag insertion actions through two bagging channels on the left and right sides, respectively, so that the reagent kit and desiccant can be delivered into the corresponding aluminum foil bags within the same packaging cycle.

[0025] Specifically, during the packaging process, the reagent kit can be provided by the front-end feeding mechanism, the desiccant can be provided by the desiccant feeding mechanism, and the aluminum foil bags to be packaged can be provided by the aluminum foil bag feeding mechanism, so that the aluminum foil bags, reagent kits and desiccants are in a corresponding relationship at the packaging position.

[0026] The packaging method for this reagent kit includes the following steps: S1, perform anti-adhesion pretreatment on the stacked aluminum foil bags. The anti-adhesion pretreatment includes micro-vibration, static elimination and layered air blowing, so that the aluminum foil bags at the top of the stack are in a pre-separated state.

[0027] Aluminum foil bags are typically stored in storage bins or warehouses in multiple stacks. Because aluminum foil bags are thin and have a flat surface, adjacent bags can easily stick together due to surface adhesion, electrostatic adsorption, or localized negative pressure. Directly sucking up these bags can easily result in multiple bags being sucked up at once, failure to remove bags, or bags not opening properly. Therefore, before removing the bags, the stacked aluminum foil bags must undergo an anti-sticking pre-treatment to ensure that the top layer of aluminum foil bags is initially separated from the layers below.

[0028] In practice, slight vibration can cause a slight relative displacement of the aluminum foil bags on the top of the bag stack, static electricity elimination can weaken the electrostatic adsorption on the bag surface, and layered air blowing can guide the airflow to the bonding interface between the upper and lower bags, so that the top aluminum foil bags form a pre-separated state suitable for single-sheet extraction.

[0029] S2, the pre-separated aluminum foil bag is extracted by a bag-taking mechanism with a vibrating adsorption head 41 and a splitting nozzle 42, and the bag opening is pre-opened by spraying airflow into the bag opening through the splitting nozzle 42 during the extraction process.

[0030] The bag-retrieving mechanism is used to remove aluminum foil bags that have already been pre-separated from the bag magazine and transfer them to the subsequent bagging position. During bag retrieval, the vibrating adsorption head 41 contacts the upper surface of the aluminum foil bag and forms a negative pressure adsorption, extracting the top aluminum foil bag through adsorption force; at the same time, the vibrating adsorption head 41 generates a small vibration in the early stage of bag retrieval, further separating the adsorbed top aluminum foil bag from the bag body below which may still have slight adhesion, thereby reducing the probability of retrieving the bag together.

[0031] Furthermore, the split-opening nozzle 42 sprays air towards the bag opening area during the bag retrieval process, creating a partial opening gap at the bag opening, thus pre-opening the bag opening. This "retrieve bag, pre-open bag" method does not wait until the aluminum foil bag is completely transferred before opening; instead, airflow pre-treatment is performed on the bag opening during the retrieval process, causing the bag opening area to break away from a tightly sealed state in advance. In this way, when the aluminum foil bag enters the subsequent opening position, the collaborative opening mechanism can more easily act on the upper and lower sides of the bag opening, reducing problems such as insufficient suction cup adsorption, opening failure, or prolonged opening time caused by a completely sealed bag opening.

[0032] S3, the bag opening in the pre-opened state is opened a second time by the coordinated bag opening mechanism. In this process, the air opening nozzle 51 inside the bag injects airflow into the aluminum foil bag to make the bag expand. The upper and lower suction cups 522 work together to open the bag opening and keep the bag opening open to form a feeding channel. In the two bag filling channels on the left and right, the reagent kit and desiccant are loaded into the corresponding aluminum foil bags through the corresponding feeding channels.

[0033] After the aluminum foil bag undergoes pre-opening at the bag-receiving stage, it is delivered to the bagging position. At this point, the bag-opening mechanism performs a secondary opening, transforming the bag opening from a partially pre-opened state to a fully open state capable of stably receiving materials. Specifically, the internal air-spreading nozzle 51 injects airflow into the aluminum foil bag, creating a supporting airflow inside the bag and causing it to expand. Simultaneously, the upper and lower suction cups 522 respectively adhere to the upper and lower sides of the bag opening and pull the bag opening apart in mutually distancing directions, keeping the bag opening open during the bagging process.

[0034] After the inlet channel is formed at the bag opening, the reagent kits and desiccants in the left and right bagging channels are respectively loaded into the corresponding aluminum foil bags through their respective inlet channels. The term "corresponding" here means that each bagging channel has a corresponding aluminum foil bag opening, inlet path, and material pushing position, so that the left and right channels can complete the bagging action in parallel, rather than forcibly feeding the materials from both channels into the same bag opening.

[0035] The working principle of this invention is as follows: During operation, the aluminum foil bags stacked in the bag storage are first subjected to micro-vibration, static elimination, and layered air blowing to prevent sticking. This creates a pre-separation state between the aluminum foil bags at the top of the stack and those below, reducing the risk of bag sticking due to surface adhesion, electrostatic adsorption, or vacuum adsorption. Subsequently, the bag-retrieving mechanism uses the vibrating adsorption head 41 to adsorb and extract the pre-separated aluminum foil bags. At the same time, the opening nozzle 42 sprays airflow into the bag opening area, causing the bag opening to form a preliminary pre-opened state during the bag-retrieving process. After the aluminum foil bags are transferred to the bagging position, the bag-opening mechanism performs a secondary opening of the pre-opened bag opening. The bag-opening nozzle 51 injects airflow into the aluminum foil bag to inflate the bag, and the upper and lower suction cups 522 act on the upper and lower sides of the bag opening respectively and work together to pull it open. The bag opening is kept stably open, forming an infeed channel for materials to enter. Finally, in the two bagging channels on the left and right, the reagent kit and desiccant are respectively loaded into the corresponding aluminum foil bags through the corresponding infeed channels, thus completing the dual-channel parallel bagging process of reagent kit and desiccant. This solution achieves pre-opening of the bag opening through the splitting nozzle 42 in the bag-removing stage, and then completes the secondary opening of the bag through the cooperation of the bag-opening nozzle 51 and the upper and lower suction cups 522. This makes the aluminum foil bag form a continuous connection from separation, extraction, pre-opening to stable opening, avoiding the problem of unstable bag opening caused by relying on single adsorption or single blowing. Moreover, the two bagging channels on the left and right can complete the loading of reagent kit and desiccant respectively after the bag opening is stably opened, thus achieving stable opening of aluminum foil bags and efficient and reliable loading of reagent kit and desiccant.

[0036] In this embodiment, it is further explained that the following steps are included before step S3: S201, the reagent kits output from the upstream single channel are sequentially intercepted and separated, and distributed to the left and right conveying channels, so that the left and right conveying channels supply materials at the same pace; During the interception and separation process, single-piece release control is implemented for continuously arriving reagent kits, ensuring that only one reagent kit is allowed to enter the corresponding conveying channel in each cycle. When the reagent kit at the end of the corresponding conveying channel is detected to be in place, a pressing-in action is performed to allow the reagent kit to enter the material trough corresponding to the aluminum foil bag.

[0037] Specifically, after the reagent kits are sequentially input from the upstream equipment in a single-channel manner, they first undergo a flow interception and separation process to separate the continuously arranged reagent kits into individual units, avoiding posture interference or rhythm disorder caused by multiple reagent kits entering the sorting position at the same time. Subsequently, the individual reagent kits are alternately or distributed to the left and right conveying channels according to preset rules through a sorting action, so that the two conveying channels can deliver the reagent kits to the subsequent bagging position with the same or matching feeding rhythm.

[0038] Furthermore, in each cycle, only one reagent kit is allowed to enter the corresponding conveyor channel, and a positioning detection system confirms that the reagent kit has reached the end of the corresponding conveyor channel. Once the reagent kit is detected to be in position, a pressing-in action is performed, changing the reagent kit from the conveying state to the pre-bagging positioning and carrying state, and placing it into the material trough that matches the position of the corresponding aluminum foil bag opening. This ensures that the reagent kit has completed single-piece processing, dual-channel allocation, and trough positioning before entering the bagging station, reducing the risk of misalignment, omissions, or jamming during subsequent material pushing and bagging.

[0039] In this embodiment, it is further explained that the steps before step S3 and after step S201 include: S202 uses a vibratory feeder to orient and convey the desiccant into individual particles, and buffers and blocks the desiccant during the conveying process to form a continuous feeding queue. Since desiccants are usually in the form of bags, flakes, or small packages, they are lightweight and their posture is not easily stable. If they are directly fed into the conveying station, problems such as overlapping, clumping, skewing, or inconsistent spacing can easily occur. Therefore, a vibratory feeder is used to orient the desiccant, gradually adjusting the randomly piled desiccant into an arrangement suitable for conveying, and then outputting it piece by piece along the conveying path.

[0040] Furthermore, a buffer material preparation barrier is set up during the conveying process so that the desiccant that has been oriented forms a continuous feeding queue before entering the pushing position. This feeding queue can not only ensure a stable material source for subsequent pushing actions, but also prevent the desiccant from rushing directly into the pushing position due to the inertia of continuous conveying.

[0041] S203: After the desiccant that has reached the desiccant pushing position is pushed to a preset height that is higher than or level with the material trough, a direct pushing operation is performed to allow the desiccant to enter the corresponding material trough. Specifically, after direct push, the desiccant is detected to be in place. If no in place signal is detected, at least one abnormal handling action is triggered, such as shutdown alarm, removal of the rejection mark, or re-push.

[0042] Once the desiccant is delivered to the desiccant delivery position, an upward lifting action first raises the desiccant to a preset height above or level with the material trough. This ensures that the bottom of the desiccant or the delivery reference surface is aligned with the inlet position of the material trough, preventing the desiccant from being obstructed by the edge of the material trough during the direct push process, thus avoiding overturning, jamming, or displacement. Subsequently, a direct push action is executed to deliver the desiccant along the preset delivery direction into the corresponding material trough, establishing a predetermined relative position between the desiccant and the already positioned reagent kit.

[0043] Furthermore, after the direct push is completed, a desiccant positioning detection is performed to determine whether the desiccant has entered the target position of the material trough. If no positioning signal is detected, it indicates that there may be a situation such as the desiccant not being pushed out, being lost during push, being stuck, or having an abnormal posture. At this time, at least one abnormal handling action is triggered, such as a shutdown alarm, removal of the rejection mark, or re-push.

[0044] In this embodiment, step S1 specifically includes: S11, perform micro-vibration treatment on the stacked aluminum foil bags to cause relative slippage of the upper layer of bags in the bag stack, so as to break the surface vacuum adsorption effect between adjacent bags. Because aluminum foil bags are relatively thin and their surfaces easily adhere to each other over a large area, when bags are stacked for a long time, a surface adhesion effect similar to vacuum adsorption may occur between adjacent bags. This can cause the bag-picking mechanism to pick up the top layer of aluminum foil bags, easily pulling up the lower layers as well. Therefore, by performing micro-vibration on the bag stack, slight disturbances are created in the horizontal or vertical directions of the upper layer of bags, causing a slight relative slippage between the top layer of aluminum foil bags and the lower layers, thus disrupting the continuous adhesion between the bag surfaces.

[0045] As an optional implementation, the micro-vibration can be performed intermittently, for example, each vibration lasting 0.1s to 1s, with a short pause between adjacent vibrations to prevent the bag stack from becoming scattered or shifting position. This reduces the separation resistance when the top aluminum foil bag is picked up individually, while maintaining the stability of the stacking reference of the aluminum foil bags within the bag storage.

[0046] S12, while or after micro-vibration, perform electrostatic elimination treatment to reduce the electrostatic adsorption effect between the upper bags of the bag stack to below a preset threshold. Aluminum foil bags easily accumulate static electricity during stacking, handling, or friction, especially in dry environments. Static electricity can cause adhesion between adjacent bags, and even after slight vibration, the bags may still re-adhere due to electrostatic attraction. Therefore, during or after slight vibration, a neutralizing airflow can be released into the upper layer of the bag stack using ionizers, ionizer nozzles, or other static elimination components. This neutralizes the static charge on the surface of the aluminum foil bags and reduces the electrostatic adsorption effect between the bags in the upper layer of the stack to below a preset threshold.

[0047] As an optional implementation, the surface potential of the upper layer of the bag stack can be detected by an electrostatic detection sensor. When the surface potential drops to a set range, it is determined that the electrostatic elimination process meets the requirements for subsequent layered bag removal.

[0048] S13, after static electricity is eliminated, layered air blowing is performed. The layered air blowing is applied to the upper layer of the bag stack in a pulse manner, so that a pre-separation gap is formed between the uppermost aluminum foil bag and the lower aluminum foil bag, which can be stably separated by the bag picking mechanism. Among them, micro-vibration, static elimination and stratified air blowing are performed in a preset order, and the completion of the step is determined by the pre-separation gap reaching the preset gap threshold.

[0049] Specifically, layered air blowing involves spraying pulsed airflow from a nozzle towards the upper edge of the bag stack or the side of the bag opening. The airflow enters along the interface between adjacent bags, thus slightly lifting or blowing open the top layer of aluminum foil bags. The purpose of using a pulsed method is to create a momentary separation effect, rather than continuously blowing the entire bag stack, avoiding large-scale warping, scattering, or misalignment of the aluminum foil bags. As an optional implementation, the pre-separation gap can be indirectly determined through photoelectric detection, distance detection, or negative pressure adsorption stability at the bag-removing end; once a gap meeting the bag-removing requirements is formed between the top layer of aluminum foil bags and the layers below them, the subsequent bag-removing steps can proceed.

[0050] In this embodiment, step S3 further includes: S31. After completing the secondary bag opening and forming the feeding channel, the bag opening area is checked for bag opening status to determine whether there is material obstruction or foreign object interference at the bag opening. Specifically, after the air nozzle 51 and upper and lower suction cups 522 are opened inside the bag to complete the secondary bag opening, although the aluminum foil bag opening has been opened and a material inlet channel has been formed, the bag opening may still be obstructed due to bag wrinkles, local rebound of the bag opening, premature proximity of the reagent kit corners to the bag opening, or desiccant displacement. Therefore, by performing bag opening status detection on the bag opening area, it is possible to determine whether there is material obstruction, foreign object interference, or insufficient bag opening at the bag opening before the material pushing action begins.

[0051] As an optional implementation, the bag opening status detection can be achieved by at least one of photoelectric detection, vacuum status feedback, displacement detection, or visual detection; when the detection result meets the preset smooth conditions, the subsequent pushing action is allowed to be executed; when the detection result does not meet the preset smooth conditions, the bag insertion action of the corresponding channel is suspended or an abnormality is triggered.

[0052] S32, during the process of pushing the reagent kit and desiccant into the aluminum foil bag through the feed channel, pressure is applied to the desiccant to limit it, so that the desiccant is confined within the preset push path during the push process, and a guide channel is formed on the preset push path to prevent the desiccant from flying up or deviating.

[0053] Because desiccants are typically small and lightweight, and are easily affected by the pusher, airflow disturbances, or the edges of the reagent kit during the feeding process, they may tilt, fly up, deflect, or flip. If the desiccant deviates from the preset feeding path, it may get stuck at the bag opening, fall onto the edge of the bag opening, or fail to enter the bag along with the reagent kit. Therefore, pressure is applied to the desiccant during the feeding process to constrain it in both the vertical and lateral directions, ensuring it enters the aluminum foil bag along the preset feeding path. In practice, a guide channel can be formed using a pressure cover, a limiting pressure plate, a guide cover, or a follower pressure component, confining the desiccant within the controlled space between the pusher and the guide channel.

[0054] In this embodiment, specifically, after step S3, the following is also included: S4. After bagging, perform online testing on the materials inside the bag and mark the non-conforming products based on the test results; Specifically, after the reagent kit and desiccant are pushed into the aluminum foil bag through the feeding channel, the state of the material inside the bag can be detected online by the bag detection mechanism. The detection content can include whether the reagent kit is present, whether the desiccant is present, whether the material has completely entered the bag, whether the material is staying in the bag opening area, and whether the material posture is obviously abnormal.

[0055] Online inspection can be performed using at least one of photoelectric detection, proximity detection, pressure feedback detection, or image detection. If the inspection results show that the material inside the bag meets the preset requirements, the aluminum foil bag will proceed to the subsequent heat-sealing process. If the inspection results show that there is leakage, incomplete filling, material clamping at the bag opening, or abnormal material position, a non-conforming mark will be generated for the product, enabling the subsequent packaging, conveying, or rejection mechanisms to perform differentiated processing based on this mark.

[0056] S5 heat-seals the aluminum foil bags after packaging, automatically rejects unqualified products based on the marking results, and transports qualified products to the palletizing station to complete the packaging.

[0057] Specifically, for qualified aluminum foil bags, heat sealing is performed, where the bag opening is heated and compressed to form a closed structure, thus stably sealing the reagent kit and desiccant inside the aluminum foil bag. For products marked as unqualified, they can be removed from the qualified product transport path via rejection, diversion, or handling mechanisms in subsequent transport routes. Furthermore, qualified products, after heat sealing, are transported to the palletizing station for further processing, forming a continuous automated packaging output process.

[0058] In this embodiment, step S5 specifically includes: S51, Before heat sealing, perform positioning and shaping treatment on the packaged aluminum foil bag to correct the wrinkles or posture deviations of the aluminum foil bag so that the bag opening is in a flat and aligned state; Because aluminum foil bags may develop wrinkles, lateral deviations in the bag opening, misalignment of the upper and lower bag surfaces, or localized warping during the bag removal, opening, and filling processes, direct heat sealing can easily lead to crooked seals, uneven seal widths, material jamming, or partial incomplete seals. Therefore, before heat sealing, the filled aluminum foil bags undergo positioning and shaping treatment to ensure a stable posture at the heat-sealing position. Specifically, this can be achieved through at least one of the following methods: lateral pushing, clamping and positioning, flattening and shaping, or guiding and limiting, to align the two edges of the bag opening and ensure that the upper and lower bag surfaces are flat and adhered.

[0059] S52 sets the heat sealing temperature control parameters according to the material and size of the aluminum foil bag, and performs closed-loop control of the heating temperature during the heat sealing process, so that the bag opening is softened by heat and the fusion seal is completed under the action of pressure. Different aluminum foil bags may have different composite layer structures, thicknesses, hot-melt layer materials, and bag opening widths, resulting in differences in the required heat-sealing temperature, pressing time, and pressing force. If the temperature is too low, the hot-melt layer at the bag opening will not soften sufficiently, easily leading to a loose seal. If the temperature is too high, it may cause the bag to be scalded, deformed, or the heat-sealed edges to melt excessively. Therefore, heat-sealing temperature control parameters can be set according to the material and size of the aluminum foil bag, and the heating temperature can be controlled in a closed loop through temperature detection components during the heat-sealing process to keep the heating temperature within the preset range. Furthermore, after the bag opening is softened by heat, pressing force is applied to the bag opening through the upper and lower pressing components, causing the hot-melt layers on the inside of the bag opening to fuse together and form a continuous seal.

[0060] S53, during the heat sealing process, simultaneously performs heat transfer printing of production date or batch number information. Specifically, during heat sealing, the production date, batch number, or other traceability information can be heat-transferred to a pre-defined marking area on the aluminum foil bag, allowing the product to acquire identifiable production information while it is being sealed. This method eliminates the need for separate inkjet printing or labeling cycles after heat sealing, reducing secondary positioning errors of the bag and decreasing the number of workstations in the packaging process.

[0061] Example 2: Combination Figures 1 to 5 As shown, the present invention also provides a dual-channel reagent kit combination packaging device, employing the dual-channel reagent kit combination packaging method described above. The reagent kit combination packaging device includes: Rack 10; The aluminum foil bag storage 20 is mounted on the frame 10 and has a carrying space for carrying multiple stacked aluminum foil bags in the vertical direction. An anti-adhesion treatment component 30 is disposed on one side of the aluminum foil bag storage 20 and is arranged correspondingly to the upper aluminum foil bag in the aluminum foil bag storage 20. A bag-taking assembly 40 is located between the aluminum foil bag storage 20 and the bagging station. The bag-taking assembly 40 includes a vibrating suction head 41 and a dispensing air nozzle 42. The collaborative bag opening component 50 is set at the bag filling station 11. The collaborative bag opening component 50 includes an in-bag opening nozzle 51 and suction cups 52 located on the upper and lower sides of the aluminum foil bag opening, respectively. The dual-channel alignment component 60 is located on one side of the bagging station. The dual-channel alignment component 60 includes a first material channel and a second material channel arranged side by side. The first material channel and the second material channel are respectively aligned with the opening of the corresponding aluminum foil bag.

[0062] During operation, the aluminum foil bag storage unit 20 first vertically carries and supplies multiple layers of stacked aluminum foil bags. The anti-adhesion treatment component 30 acts on the upper layer of aluminum foil bags in the storage unit, using vibration, static elimination, or air blowing to pre-separate the uppermost layer of aluminum foil bags from the lower layers. Subsequently, the bag-retrieving component 40, located between the aluminum foil bag storage unit 20 and the bagging station, activates. The vibrating suction head 41 adsorbs and extracts the pre-separated aluminum foil bags, while the opening nozzle 42 sprays airflow towards the bag opening, pre-opening the bag opening during the transfer process. After the aluminum foil bags are transferred to the bagging station, the bag-opening component 50 adjusts the bags. The bag is opened a second time. Inside the bag, an air nozzle 51 blows air into the bag to inflate it. Suction cups located on the upper and lower sides of the bag opening attract and pull the bag opening open, keeping it stably open and forming a feeding channel. At the same time, the first and second material channels in the dual-channel alignment component 60 transport the reagent kit and desiccant to the corresponding bagging positions and align their outlets with the corresponding aluminum foil bag openings. Then, the reagent kit and desiccant are pushed into the corresponding aluminum foil bags through the corresponding feeding channels, thereby realizing continuous automated operation of aluminum foil bag supply, bag retrieval, pre-opening, secondary opening, and left and right dual-channel alignment bagging.

[0063] In this embodiment, it is further explained that the bag-retrieving component 40 includes: The vibration adsorption head 41 is set at the bag picking end of the bag picking assembly 40 and is positioned toward the upper aluminum foil bag in the aluminum foil bag storage 20. The separating air nozzle 42 is located on one side or below the vibrating adsorption head 41, and the airflow jet direction of the separating air nozzle 42 is towards the opening area of ​​the aluminum foil bag. The adsorption position of the vibrating adsorption head 41 and the air jet landing point of the separating air nozzle 42 are both located on the same side of the aluminum foil bag opening, so as to adsorb and extract the aluminum foil bag opening and separate it by air blowing during the bag removal process.

[0064] It should be noted that the bag-picking assembly 40 is used to extract individual aluminum foil bags and perform initial separation of the bag openings between the aluminum foil bag storage 20 and the bagging station. Specifically, the vibrating adsorption head 41 is located at the bag-picking end of the bag-picking assembly 40 and is positioned towards the upper layer of aluminum foil bags in the bag storage, so that it can directly act on the surface of the uppermost aluminum foil bag when the bag-picking action begins, forming a stable grip through negative pressure adsorption; at the same time, the vibrating adsorption head 41 generates a small vibration during the adsorption process, further loosening the adsorbed aluminum foil bag from the adjacent lower bag body, reducing the risk of taking out bags together.

[0065] The separating nozzle 42 is positioned on one side or below the vibrating adsorption head 41, with its airflow directed towards the aluminum foil bag opening area. This allows the airflow to enter the edge of the bag opening during the bag removal process, creating an initial gap between the upper and lower bag surfaces at the opening. Since the adsorption position of the vibrating adsorption head 41 and the airflow landing point of the separating nozzle 42 are both located on the same side of the aluminum foil bag opening, the bag removal assembly 40 can simultaneously complete adsorption extraction and air-blowing separation within the same local area. This allows the bag opening to be pre-opened before being transferred to the bagging station, providing a stable foundation for the subsequent secondary opening by the collaborative bag opening assembly 50.

[0066] In this embodiment, it is further explained that in the collaborative bag opening component 50: The inner opening nozzle 51 is arranged along the opening direction of the aluminum foil bag opening, and the inner opening nozzle 51 has an air outlet end that can extend into the inside of the aluminum foil bag opening. The suction cup 52 includes an upper suction cup 521 and a lower suction cup 522. The upper suction cup 521 is located on the upper side of the opening of the aluminum foil bag, and the lower suction cup 522 is located on the lower side of the opening of the aluminum foil bag. The bag opening nozzle 51, upper suction cup 521 and lower suction cup 522 are distributed around the opening of the aluminum foil bag, so as to form the feeding channel of the aluminum foil bag by blowing air into the bag and pulling it open with suction from the top and bottom.

[0067] It should be noted that the inner opening nozzle 51 is set along the opening direction of the aluminum foil bag mouth, and its air outlet can extend into the inner side of the aluminum foil bag mouth, so that the airflow is sent from the bag mouth to the inside of the bag body, thereby forming an opening effect on the inside of the bag body, and preventing the bag body from being affected by the formation of the material inlet channel due to flexible collapse; at the same time, the upper suction cup 521 and the lower suction cup 522 are located on the upper and lower sides of the bag mouth, respectively, and respectively adsorb the bag surface on the upper and lower sides of the bag mouth. With the help of the air blowing from the inner opening nozzle 51, the bag mouth is pulled open in a direction away from each other.

[0068] Because the air nozzle 51, upper suction cup 521 and lower suction cup 522 inside the bag form a multi-directional cooperation relationship around the opening of the aluminum foil bag, the air blowing inside the bag can provide internal expansion support, and the upper and lower suction cups 522 can provide external pulling and holding function. Together, they can change the bag opening from a partially pre-open state to a stable open feeding channel.

[0069] The above-described embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
