Description

Technical Field

[0001] This invention relates to the field of adhesive preparation and production technology, specifically to packaging equipment for the preparation and production of two-component automotive adhesives. Background Technology

[0002] The automotive manufacturing industry has stringent requirements for the performance and batch stability of two-component structural adhesives and sealing adhesives. The filling and packaging process of finished adhesive products is the core link between preparation and production and end application, which directly determines the storage stability, mixing accuracy and final performance of adhesive products.

[0003] Existing automotive two-component adhesive filling and packaging equipment typically uses an independently set external scraping mechanism to clean residual adhesive from the nozzle, while a fixed positioning groove radially limits the two-cavity packaging container. However, the movement of this external scraping mechanism cannot be synchronized with the lifting and filling action of the packaging container. This easily leads to residual adhesive dripping from the nozzle or incomplete cleaning of adhesive splatter on the inner wall of the container. Residual adhesive can easily cause cross-contamination between the two components, resulting in premature curing of the adhesive during storage. Furthermore, the fixed positioning groove only achieves single-point container limiting and cannot guarantee the coaxiality of the container and nozzle throughout the entire filling process. During filling, the nozzle may become eccentric, scraping the wall and causing deviations in the filling volume of the single component, compromising the intended mixing ratio accuracy of the two-component adhesive and affecting the stability of the finished product's bonding performance. Therefore, this paper proposes a packaging equipment for the preparation and production of automotive two-component adhesives. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a packaging equipment for the preparation and production of two-component automotive adhesives, thereby solving the technical problems of premature curing of the adhesive during storage due to cross-contamination between the two components and deviations in the filling volume of a single component caused by eccentric scraping of the discharge nozzle.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a packaging equipment for the preparation and production of automotive two-component adhesives, comprising: The workbench and two sets of storage tanks symmetrically arranged on the back of the workbench are provided. The discharge end of the storage tank is connected to a metering pump, and the discharge end of the metering pump is connected to a conduit. A fixed base, a first sealing assembly and a second sealing assembly are respectively installed on the front of the workbench. A main control circuit board is installed in the inner cavity of the workbench. The first sealing assembly includes a first hydraulic component, a first sealing column and a first sealing seat. The second sealing assembly includes a second hydraulic component, a second sealing column, a second sealing seat and a third hydraulic component. A dual-channel filling head is mounted on a fixed base. The inlet end of the dual-channel filling head is connected to the outlet end of the conduit. Annular scraper sleeves are coaxially nested on the outer wall of the outlet of the dual-channel filling head. A linkage bracket is installed between the annular scraper sleeves. Guide rods are installed on both sides of the linkage bracket. Linear bearings that slide and adapt to the guide rods are installed on both sides of the fixed base. Compression reset components are provided between the bottom of the fixed base and the top of both sides of the linkage bracket. A trigger rod is installed at the center of the linkage bracket. A limit buffer pad is installed at the bottom of the fixed base corresponding to the trigger rod. A sliding cavity is opened on the front of the workbench, and a sliding seat is slidably connected to the inner cavity of the sliding cavity. A lifting electric rod connected to the sliding seat is installed at the top of the inner cavity of the sliding cavity. The sliding seat is connected to a filling card holder through the sliding cavity, and a double-cavity packaging container is clamped in the center of the filling card holder. The double-cavity packaging container is located directly below the discharge nozzle of the double-channel filling head.

[0006] The prepared automotive two-component adhesive is conveyed into the storage tank to complete material preparation. The equipment operating parameters are set via the main control circuit board, confirming that all actuators are in initial standby mode. The dual-cavity packaging container is clamped and fixed into the filling card holder, completing the positioning and clamping of the container to be filled. The lifting electric rod is activated, causing the sliding seat to slide upwards along the sliding cavity groove, simultaneously moving the filling card holder and the dual-cavity packaging container towards the dual-path filling head.

[0007] After the top of the dual-cavity packaging container contacts the trigger rod, it pushes the linkage bracket to move upward along the guide direction of the guide rod and the linear bearing, and simultaneously drives the annular scraper sleeve to slide upward along the outer wall of the discharge nozzle of the dual-path filling head until the trigger rod contacts the limit buffer pad. At this time, the discharge nozzle of the dual-path filling head extends into the corresponding cavity of the dual-cavity packaging container, completing the alignment preparation before filling.

[0008] The metering pumps are started, and the adhesive in the tanks is metered and dispensed according to a preset ratio through the corresponding metering pumps. This is then conveyed through conduits to the dual-channel filling head, and simultaneously poured into the corresponding chambers of the dual-cavity packaging container through the nozzles of the dual-channel filling head, completing the adhesive filling operation. After filling, the lifting electric rod drives the sliding seat to slide downwards along the sliding cavity groove, simultaneously moving the filling clamping seat and the dual-cavity packaging container away from the dual-channel filling head.

[0009] The compression reset component includes a compression reset spring, etc. The compression reset component pushes the linkage bracket to reset downward along the guide direction of the guide rod and the linear bearing, and simultaneously drives the annular scraper sleeve to slide downward along the outer wall of the discharge nozzle of the dual-channel filling head. During the separation of the dual-cavity packaging container and the dual-channel filling head, the annular scraper sleeve simultaneously completes the scraping of residual adhesive on the outer wall of the discharge nozzle, and at the same time completes the cleaning of adhesive splashed on the inner wall of the cavity of the dual-cavity packaging container, until all components are reset to the initial standby state.

[0010] Remove the filled double-cavity packaging container and place the matching piston at the cavity opening. Depending on the model of the double-cavity packaging container, place it in the first sealing slot of the first sealing assembly or the second sealing slot of the second sealing assembly. When operating with the first sealing assembly, the first hydraulic component moves the first sealing column towards the double-cavity packaging container, pressing the piston into the cavity opening to complete the sealing operation. The first hydraulic component includes: a first servo hydraulic cylinder, etc.

[0011] When the second sealing assembly is used, the third hydraulic component first lifts the second sealing seat and the double-cavity packaging container to the corresponding position in the direction of the second sealing column. The second hydraulic component drives the second sealing column to move in the direction of the double-cavity packaging container, pressing the piston into the cavity of the double-cavity packaging container to complete the sealing operation, and finally completes the complete packaging process of the automotive two-component adhesive. The second hydraulic component includes: the second servo hydraulic cylinder, etc., and the third hydraulic component includes: the third servo hydraulic cylinder, etc.

[0012] Preferably, grooves are provided between the bottom of the fixed base and the top two sides of the linkage bracket, and both ends of the compression reset member extend into the inner cavity of the groove and fit against the inner wall.

[0013] During equipment assembly, both ends of the compression reset component are embedded into the corresponding grooves in the fixed base and the linkage bracket, ensuring a tight fit between the ends of the compression reset component and the inner wall of the groove. During equipment operation, when the linkage bracket is pushed upwards by the trigger rod, the compression reset component undergoes elastic deformation under pressure within the groove. During the downward reset process of the linkage bracket, the compression reset component releases elastic potential energy within the groove, propelling the linkage bracket to a smooth reset.

[0014] Preferably, the lifting end of the first hydraulic component is connected to the first sealing post, and the first sealing bracket is located directly below the first sealing post.

[0015] When the first sealing assembly is in operation, the double-cavity packaging container to be sealed is positioned in the first sealing holder. The first hydraulic component is activated, and the lifting end of the first hydraulic component drives the first sealing column to move towards the first sealing holder, performing a pressing and sealing operation on the piston on the double-cavity packaging container. After the operation is completed, the first hydraulic component drives the first sealing column to return to the initial position.

[0016] Preferably, the second hydraulic component is located directly above the third hydraulic component, and the telescopic end of the second hydraulic component is connected to the second sealing post.

[0017] When the second sealing assembly is in operation, the second hydraulic component is activated. The telescopic end of the second hydraulic component drives the second sealing column to move towards the third hydraulic component. In conjunction with the lifting action of the third hydraulic component, the piston on the double-cavity packaging container is pressed and sealed. After the operation is completed, the second hydraulic component drives the second sealing column to return to its initial position.

[0018] Preferably, the second sealing bracket is located between the second hydraulic component and the third hydraulic component, and the telescopic end of the third hydraulic component is connected to the second sealing bracket.

[0019] When the second sealing component is in operation, the double-cavity packaging container to be sealed is positioned in the second sealing holder. The third hydraulic component is activated, and the telescopic end of the third hydraulic component moves the second sealing holder and the double-cavity packaging container toward the second sealing column to the corresponding position. The sealing operation is completed by cooperating with the second hydraulic component to drive the second sealing column to press. After the operation is completed, the third hydraulic component drives the second sealing holder to return to the initial position.

[0020] Preferably, the bottom of the inner cavity of the injection card holder is provided with a storage groove around the perimeter, and the inner side of the storage groove is rotatably connected to a rotating shaft, and a transmission shaft is connected between adjacent rotating shafts.

[0021] Before clamping the dual-cavity packaging container, the inclined clamping plate is housed within the inner cavity of the receiving slot. After the dual-cavity packaging container is placed within the inner cavity of the filling clamping seat, the rotating shaft is driven to rotate, synchronously driving the adjacent rotating shaft to rotate synchronously via the transmission shaft. This causes the inclined clamping plate to rotate out of the receiving slot, performing a positioning and clamping operation on the dual-cavity packaging container. After the filling operation is completed, the rotating shaft rotates in the reverse direction, causing the inclined clamping plate to retract into the receiving slot, releasing the clamping limit on the dual-cavity packaging container.

[0022] Preferably, the surface of the rotating shaft is fitted with a sloping plate that is compatible with the storage groove, and the sloping surface of the sloping plate fits against the perimeter of the double-cavity packaging container.

[0023] When the shaft rotates, it drives the inclined clamping plate to rotate synchronously, so that the inclined surface of the clamping plate fits tightly against the outer wall of the double-cavity packaging container, completing the positioning and clamping of the double-cavity packaging container. During the filling operation, the inclined clamping plate continuously forms a fitting limit on the double-cavity packaging container. After the operation is completed, the shaft rotates in the opposite direction, causing the inclined clamping plate to disengage from the double-cavity packaging container and retract into the storage tank.

[0024] Preferably, the lower two sides of the surface of the injection card holder are rotatably connected to rotating wheels, and a transmission wheel meshes between adjacent sets of rotating wheels.

[0025] When the drive motor starts, it drives the transmission wheel to rotate. The transmission wheel, through meshing, drives the rotating wheels on both sides to rotate synchronously in opposite directions, providing synchronous transmission power for the rotation of the shaft. After the clamping operation is completed, the drive motor drives the transmission wheel to rotate in the opposite direction, synchronously driving the rotating wheels on both sides to rotate in the opposite direction, realizing the reset action of the clamping structure.

[0026] Preferably, a pulley is installed between the rotating end of the transmission wheel and the outer end of the shaft, and a transmission belt is added between adjacent pulleys.

[0027] When the drive wheel rotates, it drives the corresponding pulley to rotate synchronously. This, in turn, drives the pulley at the outer end of the shaft to rotate synchronously via the drive belt, thus causing the shaft to rotate and achieving the drive transmission for the clamping structure. During the reset process, the drive wheel rotates in the opposite direction, and through the transmission between the pulley and the drive belt, it drives the shaft to rotate in the opposite direction, completing the reset of the clamping structure.

[0028] Preferably, a drive motor is coaxially connected to the rotating end of the pulley on the transmission wheel, and the drive motor is connected to the injection card holder through a motor base.

[0029] When performing the clamping operation of the double-cavity packaging container, the drive motor is started. The output end of the drive motor drives the coaxially connected pulley and transmission wheel to rotate synchronously. Through the transmission structure, the rotating shaft and the inclined plate perform the clamping action. After the operation is completed, the drive motor rotates in the reverse direction, driving the transmission structure to run synchronously in the reverse direction, completing the reset of the clamping structure and releasing the limit on the double-cavity packaging container.

[0030] Compared with the prior art, the present invention provides a packaging equipment for the preparation and production of automotive two-component adhesives, which has the following beneficial effects: This packaging equipment for the preparation and production of two-component automotive adhesives uses an annular scraper sleeve coaxially nested with the discharge nozzle of the dual-channel filling head. In conjunction with the linkage structure of the linkage bracket, trigger rod, and compression reset component, it can perform scraping operations synchronously with the lifting and lowering movements of the dual-cavity packaging container, avoiding the risk of cross-contamination between the two components and premature curing caused by residues of the two-component adhesive.

[0031] The sliding fit structure of the guide rod and linear bearing ensures the coaxiality of the annular scraper sleeve and the discharge nozzle of the dual-path filling head throughout the entire process. Combined with the precise lifting structure of the filling clamp and the lifting electric rod, the coaxial limit is achieved throughout the filling process, avoiding the problem of filling volume and proportion accuracy deviation caused by the eccentric scraping of the discharge nozzle.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] This invention provides a technical solution: a packaging equipment for the preparation and production of automotive two-component adhesives, comprising: (See attached image) Figures 1-6 The workbench 1 and two sets of storage tanks 2 symmetrically arranged on the back of the workbench 1 are provided. The discharge end of the storage tank 2 is connected to a metering pump 3 and a conduit 4 is connected to the discharge end of the metering pump 3. The front of the workbench 1 is respectively equipped with a fixed base 5, a first sealing assembly 24 and a second sealing assembly 25. The main control circuit board is installed in the inner cavity of the workbench 1. The first sealing assembly 24 includes a first hydraulic component 26, a first sealing column 27 and a first sealing bracket 28. The second sealing assembly 25 includes a second hydraulic component 29, a second sealing column 30, a second sealing bracket 31 and a third hydraulic component 32. A dual-channel filling head 6 is mounted on a fixed base 5. The inlet end of the dual-channel filling head 6 is connected to the outlet end of the conduit 4. Annular scraper sleeves 7 are coaxially nested on the outer wall of the outlet of the dual-channel filling head 6. A linkage bracket 8 is installed between the annular scraper sleeves 7. Guide rods 9 are installed on both sides of the linkage bracket 8. Linear bearings that slide and adapt to the guide rods 9 are installed on both sides of the fixed base 5. Compression reset components 10 are provided between the bottom of the fixed base 5 and the top of the linkage bracket 8 on both sides. A trigger rod 11 is installed at the center of the linkage bracket 8. A limit buffer pad is installed at the bottom of the fixed base 5 corresponding to the trigger rod 11. A sliding cavity 12 is opened on the front of the workbench 1, and a sliding seat 13 is slidably connected to the inner cavity of the sliding cavity 12. A lifting electric rod 14 connected to the sliding seat 13 is installed on the top of the inner cavity of the sliding cavity 12. A filling card holder 15 is connected to the sliding cavity 12, and a double-cavity packaging container 16 is clamped in the center of the filling card holder 15. The double-cavity packaging container 16 is located directly below the discharge nozzle of the double-channel filling head 6.

[0036] By combining the independently set storage tank 2, metering pump 3 and dual-channel filling head 6, the two components of the adhesive are independently transported and synchronously filled, eliminating the risk of premature contact and curing of the two components during the packaging process, ensuring the storage stability and performance of the adhesive product, and meeting the stringent quality requirements of the automotive industry for two-component adhesives.

[0037] Through the coordinated operation of the annular scraper sleeve 7, the linkage bracket 8, the compression reset component 10, and the trigger rod 11, during the separation of the dual-cavity packaging container 16 and the dual-channel filling head 6 after filling, the residual adhesive on the outer wall of the discharge nozzle of the dual-channel filling head 6 is scraped off, and the adhesive splashed on the inner wall of the cavity of the dual-cavity packaging container 16 is cleaned. This avoids the discharge nozzle from dripping adhesive and contaminating the equipment and the container sealing surface, and eliminates the problems of subsequent sealing failure and adhesive deterioration caused by residual adhesive at the cavity opening, thus greatly improving the sealing performance of the product packaging and the finished product qualification rate.

[0038] The sliding guide mechanism of the guide rod 9 and the linear bearing ensures the coaxiality and stability of the lifting and lowering movements of the linkage bracket 8 and the annular scraper sleeve 7, preventing eccentricity and jamming during scraping. The cooperation of the sliding cavity groove 12, the sliding seat 13, and the lifting electric rod 14 enables the smooth lifting and lowering alignment of the filling clamp seat 15 and the dual-cavity packaging container 16, ensuring precise alignment between the outlet of the dual-path filling head 6 and the corresponding chamber of the dual-cavity packaging container 16. This prevents flow deviation or splashing during filling, improving the consistency of filling metering and the stability of continuous equipment operation.

[0039] Please see Figure 2Grooves are provided between the bottom of the fixed base 5 and the top two sides of the linkage bracket 8, and both ends of the compression reset member 10 extend into the inner cavity of the groove and fit against the inner wall.

[0040] By creating suitable grooves on the fixed base 5 and the linkage bracket 8, a stable installation and limiting space is provided for the compression reset component 10, preventing radial displacement or slippage of the compression reset component 10 during compression and reset, and ensuring the stable output of the elastic force of the compression reset component 10. At the same time, the inner wall of the groove forms a close-fitting support for the end of the compression reset component 10, dispersing stress concentration, extending the service life of the compression reset component 10, and further ensuring the smoothness and reliability of the lifting and lowering action of the linkage bracket 8 and the annular scraper sleeve 7.

[0041] Please see Figure 5 The lifting end of the first hydraulic component 26 is connected to the first sealing post 27, and the first sealing bracket 28 is located directly below the first sealing post 27.

[0042] The direct connection between the first hydraulic component 26 and the first sealing post 27 ensures stable transmission of pressing power, avoiding insufficient pressing force due to power transmission loss. By positioning the first sealing holder 28 directly below the first sealing post 27, the pressing direction of the first sealing post 27 during the pressing process is ensured to be coaxially aligned with the opening of the double-cavity packaging container 16, preventing deviation or jamming during piston pressing, ensuring sealing accuracy and sealing performance, and improving the pass rate of sealing operations.

[0043] Please see Figure 6 The second hydraulic component 29 is located directly above the third hydraulic component 32, and the telescopic end of the second hydraulic component 29 is connected to the second sealing post 30.

[0044] By positioning the second hydraulic component 29 directly above the third hydraulic component 32, the pressing action of the second sealing column 30 and the lifting action of the third hydraulic component 32 are ensured to be coaxially aligned, avoiding pressing deviations caused by misalignment. The direct connection between the second hydraulic component 29 and the second sealing column 30 ensures precise transmission of pressing power, flexibly adapting to the pressing stroke requirements of different models of dual-cavity packaging containers 16, and improving the operational adaptability and pressing stability of the second sealing assembly 25.

[0045] The second sealing bracket 31 is located between the second hydraulic component 29 and the third hydraulic component 32, and the telescopic end of the third hydraulic component 32 is connected to the second sealing bracket 31.

[0046] By positioning the second sealing bracket 31 between the second hydraulic component 29 and the third hydraulic component 32, a two-way coordination between the lifting and positioning of the double-cavity packaging container 16 and the piston pressing is achieved. This allows for flexible adjustment of the relative stroke of the pressing operation, adapting to the sealing requirements of double-cavity packaging containers 16 with different height specifications. The direct connection between the third hydraulic component 32 and the second sealing bracket 31 ensures the stability and positioning accuracy of the lifting action, preventing displacement and shaking of the double-cavity packaging container 16 during the pressing process, and further improving the stability and pressing accuracy of the sealing operation.

[0047] Please see Figure 3 and Figure 4 The bottom of the inner cavity of the injection card holder 15 is provided with a storage groove 17, and the inner side of the storage groove 17 is rotatably connected to a rotating shaft 18, and a drive shaft is connected between adjacent rotating shafts 18.

[0048] By creating a storage slot 17 within the cavity of the filling card holder 15, a concealed storage space is provided for the rotating shaft 18 and the inclined clamping plate 19, preventing structural components from interfering with the handling of the dual-cavity packaging container 16 and improving the convenience of container handling. A drive shaft is installed between adjacent rotating shafts 18 to achieve synchronous rotation of multiple sets of rotating shafts 18, ensuring the consistency of the actions of multiple clamping structures, avoiding the misalignment of the dual-cavity packaging container 16 caused by unilateral clamping, and improving the positioning accuracy and coaxiality of the container clamping.

[0049] The surface of the rotating shaft 18 is fitted with a sloping plate 19 that is compatible with the storage slot 17, and the sloping surface of the sloping plate 19 fits against the perimeter of the double-cavity packaging container 16.

[0050] The inclined surfaces of the sloping clamping plates 19 fit snugly against the perimeter of the double-cavity packaging container 16, forming a surface-contact clamping and limiting mechanism. Compared to point-contact clamping, this disperses clamping stress and prevents extrusion deformation damage to the outer wall of the double-cavity packaging container 16. Simultaneously, the sloping structure can accommodate the clamping requirements of double-cavity packaging containers 16 with different outer diameters, increasing the adaptability of the filling clamping seat 15. Furthermore, the synchronous fitting and limiting of multiple sets of sloping clamping plates 19 ensures that the double-cavity packaging container 16 remains coaxially centered, further improving the accuracy of filling alignment.

[0051] The lower two sides of the surface of the injection card holder 15 are rotatably connected to rotating wheels 20, and a transmission wheel 201 meshes between two adjacent sets of rotating wheels 20.

[0052] The meshing transmission between the transmission wheel 201 and the two rotating wheels 20 on both sides enables the synchronous and opposite rotation of the two sets of rotating wheels 20, ensuring the synchronicity of the action of the transmission structure on both sides and avoiding the misalignment problem of the double-cavity packaging container 16 caused by asynchronous clamping actions on both sides. The meshing transmission structure has high transmission accuracy and stable power transmission, with no risk of slippage, and can precisely control the rotation angle and clamping force of the clamping structure, further improving the stability and reliability of the clamping operation.

[0053] A pulley 22 is installed between the rotating end of the transmission wheel 201 and the outer end of the rotating shaft 18, and a transmission belt 23 is added between adjacent pulleys 22.

[0054] The pulley 22 and the drive belt 23 work together to achieve stable long-distance transmission from the drive wheel 201 to the rotating shaft 18. This allows for flexible adaptation to the structural layout of the filling clamp 15, preventing interference between the transmission structure and the container clamping space. The belt drive provides cushioning and shock absorption, reducing impact vibration during transmission and preventing vibration from being transmitted to the double-cavity packaging container 16, which could lead to filling splashing. Furthermore, the transmission structure operates with low noise and is easy to maintain, ensuring the stability of the equipment during long-term continuous operation.

[0055] The drive motor 21 is coaxially connected to the rotating end of the pulley 22 on the transmission wheel 201, and the drive motor 21 is connected to the injection card holder 15 through the motor base.

[0056] The coaxial connection between the drive motor 21 and the pulley 22 ensures direct and precise transmission of driving power, avoiding losses and deviations during power transmission, and allowing for precise control of the start, stop, and rotation angle of the clamping action. The drive motor 21 is stably connected to the injection clamping bracket 15 via a motor mount, ensuring the stability of the drive motor 21 during operation and reducing vibration transmission. Simultaneously, the drive motor 21 provides an independent power source for the clamping structure, enabling automated control of the clamping action without manual intervention, thus improving the automation level and ease of operation of the equipment.

[0057] This solution includes a main control circuit board with a logic control module, a metering pump control module, a hydraulic and electric actuator control module, an abnormal alarm and emergency stop control module, a production data storage and traceability module, and a human-machine interface module. The logic control module receives feedback signals from various actuators, outputs corresponding control commands, coordinates the coordinated operation of each process, and ensures stable execution of actions according to a preset sequence. The metering pump control module precisely controls the start / stop and delivery status of the two sets of metering pumps, ensuring the accuracy of the two-component adhesive mixing ratio and filling volume. The hydraulic and electric actuator control module controls the start / stop and operation status of the lifting electric rod 14, the first hydraulic component 26, the second hydraulic component 29, the third hydraulic component 32, and the drive motor 21, ensuring the synchronization and accuracy of the actions of each actuator. The abnormal alarm and emergency stop control module monitors the operating status of each component in real time, identifies abnormal operating conditions during equipment operation, triggers alarm signals, and executes emergency stop protection actions to ensure the safety of the equipment and operators. The production data storage and traceability module records production parameters, batch information, and operating status data during equipment operation, meeting the automotive industry's requirement for traceability throughout the entire production process. The human-machine interface module enables communication between the main control circuit board and external human-machine interface devices, supporting operators in setting operating parameters, viewing equipment operating status, and inputting operating commands.

[0058] This equipment also includes a constant temperature control component, a vacuum degassing component, an inert gas protection component, a visual inspection component, and an explosion-proof protection component. The constant temperature control component is installed on the outer wall of the storage tank 2 to maintain a constant temperature for the adhesive within the tank, stabilizing its flowability and preventing viscosity fluctuations caused by temperature changes from affecting filling accuracy and conveying stability. The vacuum degassing component is connected to the inner cavity of the storage tank 2 to perform vacuum degassing on the adhesive, removing air bubbles mixed in with the adhesive, ensuring the quality of the filled product, and preventing air bubbles from affecting the adhesive's performance. The inert gas protection component is connected to the inner cavity of the dual-channel filling head 6 and the inner cavity of the storage tank 2, used to fill the chambers of the dual-cavity packaging container 16 with inert gas during the filling process, isolating it from air, preventing the adhesive components from absorbing moisture and oxidizing, and extending the product's shelf life. The vision inspection component is installed on the front of the workbench 1, located between the filling card connector 15 and the sealing component. It is used to visually inspect the filling status and cavity cleanliness of the double-cavity packaging container 16 after filling, identify unqualified products, and issue a warning signal. The explosion-proof protection component covers the electrical actuators and pipeline joints of the equipment, providing explosion-proof protection for the electrical components and delivery pipelines. It is suitable for production scenarios involving solvent-based automotive two-component adhesives and meets the explosion-proof requirements for safe production in the workshop.

[0059] The prepared two-component automotive adhesive is conveyed into two sets of storage tanks 2. The vacuum degassing component is activated to perform vacuum degassing on the adhesive in storage tank 2, and the temperature control component is activated to maintain a constant temperature for the adhesive in storage tank 2, completing the material preparation. The operator sets the equipment operating parameters through the human-machine interface module of the main control circuit board via an external human-machine interface device. The logic control module of the main control circuit board comprehensively verifies the status of each execution component, confirming that all components are in the initial standby state.

[0060] The double-cavity packaging container 16 is placed in the center of the inner cavity of the filling card holder 15. The main control circuit board starts the drive motor 21 through the hydraulic and electric actuator control module. The drive motor 21 drives the coaxially connected pulley 22 and transmission wheel 201 to rotate synchronously. The transmission wheel 201 drives the rotating wheels 20 on both sides to rotate synchronously through meshing transmission. The pulley 22 and transmission belt 23 drive the rotating shaft 18 to rotate synchronously. The adjacent rotating shafts 18 achieve synchronous linkage through the transmission shaft. The rotating shaft 18 drives the inclined plate 19 to rotate out of the storage slot 17, so that the inclined surface of the inclined plate 19 fits tightly with the periphery of the double-cavity packaging container 16, completing the positioning, clamping and coaxial limiting of the double-cavity packaging container 16.

[0061] The main control circuit board activates the lifting electric rod 14 via the hydraulic and electric actuator control module. The lifting electric rod 14 drives the sliding seat 13 to slide upward along the sliding cavity groove 12, simultaneously moving the filling clamping seat 15 and the clamped double-cavity packaging container 16 towards the double-channel filling head 6. After the top of the double-cavity packaging container 16 contacts the trigger rod 11, it pushes the linkage bracket 8 to move upward along the guide direction of the guide rod 9 and the linear bearing, simultaneously driving the annular scraper sleeve 7 to slide upward along the outer wall of the discharge nozzle of the double-channel filling head 6. The compression reset component 10 between the fixed base 5 and the linkage bracket 8 is squeezed and undergoes elastic deformation in the corresponding groove cavity until the trigger rod 11 contacts the limiting buffer pad. At this time, the discharge nozzle of the double-channel filling head 6 extends into the corresponding cavity of the double-cavity packaging container 16, completing the alignment preparation before filling.

[0062] The main control circuit board synchronously starts the inert gas protection component and the metering pump control module through the logic control module. The inert gas protection component fills the corresponding chamber of the dual-chamber packaging container 16 with inert gas to isolate the air in the chamber. The metering pump 3 starts under the regulation of the metering pump control module. The two sets of adhesives in the storage tank 2 are quantitatively delivered by the corresponding metering pump 3, and delivered to the dual-channel filling head 6 through the conduit 4. Then, they are synchronously filled into the corresponding chamber of the dual-chamber packaging container 16 through the outlet of the dual-channel filling head 6, completing the adhesive filling operation.

[0063] After the filling operation is completed, the main control circuit board controls the lifting electric rod 14 to run in reverse through the hydraulic and electric actuator control module. The lifting electric rod 14 drives the sliding seat 13 to slide downward along the sliding cavity groove 12, and simultaneously drives the filling card seat 15 and the dual-cavity packaging container 16 to move away from the dual-path filling head 6. The compression reset component 10 releases elastic potential energy in the inner cavity of the groove, pushing the linkage bracket 8 to reset downward along the guide direction of the guide rod 9 and the linear bearing, and simultaneously drives the annular scraper sleeve 7 to slide downward along the outer wall of the discharge nozzle of the dual-path filling head 6. During the separation of the dual-cavity packaging container 16 from the dual-path filling head 6, the annular scraper sleeve 7 simultaneously completes the scraping of residual adhesive on the outer wall of the discharge nozzle, and at the same time completes the cleaning of adhesive splashed on the inner wall of the cavity of the dual-cavity packaging container 16, until all components are reset to the initial standby state.

[0064] The main control circuit board controls the drive motor 21 to run in reverse via the hydraulic and electric actuator control module. The drive motor 21 drives the transmission structure to run synchronously in reverse, and through the rotating shaft 18, it drives the inclined clamping plate 19 to disengage from the double-cavity packaging container 16 and retract it into the storage slot 17, releasing the clamping limit on the double-cavity packaging container 16. The filled double-cavity packaging container 16 is then removed from the filling clamping seat 15 and transported to the inspection station of the vision inspection component. The vision inspection component detects the filling status and cavity cleanliness of the double-cavity packaging container 16, identifies and indicates unqualified products, and transports the qualified double-cavity packaging container 16 to the sealing operation station.

[0065] Place the matching piston at the opening of the qualified double-cavity packaging container 16, and move it to the first sealing seat 28 of the first sealing assembly 24 or the second sealing seat 31 of the second sealing assembly 25 according to the model of the double-cavity packaging container 16, to complete the positioning before sealing.

[0066] When the first sealing component 24 is selected to perform the sealing operation, the main control circuit board starts the first hydraulic component 26 through the hydraulic and electric actuator control module. The lifting end of the first hydraulic component 26 drives the first sealing column 27 to move towards the double-cavity packaging container 16, pressing the piston into the cavity of the double-cavity packaging container 16 to complete the sealing operation. After the operation is completed, the main control circuit board controls the first hydraulic component 26 to drive the first sealing column 27 to reset to the initial position.

[0067] When the second sealing component 25 is selected to perform the sealing operation, the main control circuit board starts the third hydraulic component 32 through the hydraulic and electric actuator control module. The telescopic end of the third hydraulic component 32 drives the second sealing card seat 31 and the double-cavity packaging container 16 to move to the corresponding position in the direction of the second sealing post 30. The main control circuit board simultaneously starts the second hydraulic component 29. The telescopic end of the second hydraulic component 29 drives the second sealing post 30 to move in the direction of the double-cavity packaging container 16, pressing the piston into the cavity of the double-cavity packaging container 16 to complete the sealing operation. After the operation is completed, the main control circuit board controls the second hydraulic component 29 and the third hydraulic component 32 to drive the corresponding components to reset to the initial position.

[0068] The sealed double-cavity packaging container 16 is moved to the finished product unloading station, completing the entire packaging process for the automotive two-component adhesive. During equipment operation, the production data storage and traceability module on the main control circuit board records the production parameters and operating data of the entire process in real time, while the abnormal alarm and emergency stop control module monitors the equipment's operating status in real time. In the event of an abnormal condition, an alarm is triggered in a timely manner, and an emergency stop protection action is executed.
