Description

Technical Field

[0001] This utility model relates to the field of adhesive application technology, and more specifically to an adhesive application system. Background Technology

[0002] In the automotive assembly process, adhesive application is a crucial step in ensuring the secure connection and proper sealing of automotive components. To guarantee the continuity of the production line and prevent shutdowns due to sudden malfunctions of the adhesive application equipment, an adhesive application system with main and backup equipment is typically installed. The backup equipment is primarily used to temporarily operate and maintain adhesive application operations when the main equipment fails.

[0003] However, the current glue application system has significant drawbacks. Due to the relatively low failure rate of the main glue application equipment, the backup equipment remains idle for extended periods during normal production. This results in most of the glue in the backup equipment's buckets expiring and becoming unusable, forcing it into disposal and causing severe resource waste. This not only increases production costs but also imposes an unnecessary burden on the environment.

[0004] To address this issue, the industry has made numerous attempts. For example, optimizing adhesive storage methods and extending the adhesive's shelf life have not fundamentally solved the problem of expired adhesive being wasted in the glue tanks of spare glue application equipment. Other attempts have focused on periodically replacing the adhesive in the spare glue application equipment's tanks to ensure its availability, but this approach not only increases labor costs and operational complexity but also results in the waste of the replaced adhesive.

[0028] Figure 1 A schematic block diagram of an adhesive application system 100 according to some embodiments of the present invention is shown. Figure 1 As shown, the adhesive application system 100—for example, as a complete set of equipment for achieving continuous and stable adhesive application operations—may include a main adhesive application device 10, a standby adhesive application device 20, a first adhesive supply line 30 bridging the main adhesive application device 10 and the standby adhesive application device 20, and a control device 40. The control device 40 may be configured to control the main adhesive application device 10 and the standby adhesive application device 20 to achieve an adhesive supply operation mode from the standby adhesive application device 20 to the main adhesive application device 10 via the first adhesive supply line 30. It should be understood that the control device 40 may include, for example, a plurality of control devices 41, 42, such as a programmable logic controller, at least some of which may interact with each other to collaboratively control the operation of the adhesive application system 100 in different operating modes. In some embodiments, the main adhesive application device 10 may be assigned at least one control device 41, and the standby adhesive application device 20 may be assigned at least one control device 42. Additionally or alternatively, the control device 40 may also have at least one higher-level control device for interacting with control devices 41, 42 assigned to the main adhesive applicator 10 and the backup adhesive applicator 20.

[0029] In some embodiments, the adhesive application system 100 may include a human-machine interface 50. In some embodiments, the human-machine interface 50 may be communicatively connected to the control device 40. In some embodiments, the human-machine interface 50 may be integrated with the control device 40. The human-machine interface 50 may have an operating mode input module 52, in which a specific operating mode of the adhesive application system 100 can be set.

[0030] Reference Figure 2 and 3 Further detailed description Figure 1 The adhesive application system 100 shown. Figure 2 A perspective view of an adhesive application system 100 according to some embodiments of the present invention is shown, and Figure 3 It shows Figure 2A partial 3D view.

[0031] like Figure 2 and Figure 3 As shown, the main glue application equipment 10 may include at least one main glue tank 11 (exemplarily configured as two main glue tanks 11), a first distributor 12, a first glue supply assembly 13, and a first glue gun hose 14 (exemplarily configured as an automatic glue gun hose). The first glue supply assembly 13 is connected between the main glue tank 11 and the first distributor 12, and is used to deliver glue from the main glue tank 11 to the first distributor 12. The first glue gun hose 14 is connected to the output end of the first distributor 12, and is used to deliver the glue dispensed by the first distributor 12 to the glue application end. It should be understood that the first glue supply assembly 13 may be configured in various ways to realize the glue supply connection between the main glue tank 11 and the first distributor 12, and is not limited to a specific embodiment.

[0032] The standby glue application equipment 20 may include at least one standby glue tank 21 (exemplarily two standby glue tanks 21), a multi-way valve device 22, a second glue supply assembly 23, and a second glue gun hose 24 (exemplarily a manual glue gun hose). The second glue supply assembly 23 is connected between the standby glue tank 21 and the multi-way valve device 22, and is used to deliver glue from the standby glue tank 21 to the multi-way valve device 22. The second glue gun hose 24 is connected to the output end of the multi-way valve device 22, and is used to deliver the glue dispensed by the multi-way valve device 22 to the glue application end. It should be understood that the second glue supply assembly 23 may be configured in various ways to realize the glue supply connection between the standby glue tank 21 and the multi-way valve device 22, and is not limited to a specific embodiment.

[0033] Advantageously, by configuring redundant main glue tank 11 and spare glue tank 21 for the glue coating system 100, when an abnormal situation such as glue depletion, blockage or seal failure occurs in a single glue tank, glue can be supplied by switching to other redundant glue tanks to continue supplying glue, thereby ensuring the continuity, reliability and stability of glue supply of the glue coating system 100 and avoiding production interruption due to single glue tank failure.

[0034] In some embodiments, the control device 40 can be configured to control the main glue applicator 10 and the standby glue applicator 20 in a first operating mode of the glue applicator system 100, such that the standby glue applicator 20 can supply glue to the first distributor 12 of the main glue applicator 10 and then to the first glue gun hose 14 via the standby glue tank 21, the second glue supply assembly 23, and the multi-way valve device 22, while stopping the supply of glue to the first distributor 12 and then to the first glue gun hose 14 via the main glue tank 11 and the first glue supply assembly 13. It should be noted that the above-mentioned control of the main glue applicator 10 and the standby glue applicator 20 by the control device 40 can be achieved by conventional operating means in the art, specifically by manipulating the corresponding actuators (such as pumps, various valves, and other different types of actuators) to make the glue applicator system 100 reach the preset first operating mode.

[0035] This invention optimizes the adhesive supply path planning and backup adhesive consumption strategy by actively setting the first operating mode of the adhesive coating system 100. Even when the main adhesive coating equipment 10 is in a fault-free normal operating state, the adhesive in the backup adhesive coating equipment 20 can still be consumed quantitatively and orderly based on the first operating mode (e.g., according to preset time cycles, preset adhesive inventory thresholds, preset production batch intervals, and other triggering conditions). Therefore, it can both ensure the emergency adhesive supply needs of the backup adhesive supply channel can be quickly activated in case of a sudden failure in the main adhesive supply channel during production, and effectively avoid the problems of chemical performance degradation, expiration, and resource waste caused by long-term idleness of backup adhesive, significantly improving adhesive utilization efficiency and production economy.

[0036] In some embodiments, the control device 40 can be configured to control the main adhesive applicator 10 and the standby adhesive applicator 20 in a second operating mode of the adhesive application system 100, such that the main adhesive applicator 10 can supply adhesive to the first distributor 12 and then to the first glue gun hose 14 via the main glue tank 11 and the first glue supply assembly 13, while the standby adhesive applicator 20 is disabled. It should be noted that the second operating mode is the normal default operating mode of the adhesive application system 100. In this mode, the main adhesive applicator 10 maintains a continuous and stable normal operating state, and all adhesive application operations of the adhesive application system 100 are performed independently only by the main adhesive applicator 10; the standby adhesive applicator 20 is in a disabled or standby state.

[0037] In some embodiments, the human-machine interface 50 (HMI) integrates an operation mode input module 52, which has operation mode selection, parameter configuration, and / or rule storage functions. Operators can use this module to set the current operation mode (i.e., the first operation mode or the second operation mode) of the coating system 100, and can also preset the regular operation rules of the coating system 100. For example, the operation rules include, but are not limited to: setting the second operation mode to be enabled from 8:00 to 18:00 every Monday to Thursday, and the first operation mode to be enabled from 9:00 to 12:00 every Friday; and the above operation rules can be modified and stored in real time according to actual production volume, adhesive shelf life, equipment maintenance plans, and other needs, improving the operational flexibility of the coating system 100.

[0038] In some embodiments, the control device 40 may be configured to control the main glue applicator 10 and the standby glue applicator 20 in a third operating mode of the glue applicator system 100 such that the standby glue applicator 20 can supply glue to the second glue gun tube 24 of the standby glue applicator 20 via the standby glue tank 21, the second glue supply assembly 23 and the multi-way valve device 22, while the main glue applicator 10 is deactivated.

[0039] To trigger the third operating mode, the adhesive application system 100 may further include a fault detection device. In some embodiments, the fault detection device may be communicatively connected to the control device 40. In some embodiments, the fault detection device may be integrated with the control device 40. In some embodiments, the fault detection device may be configured to monitor the operating status of the main adhesive application device 10 in real time. When a fault operating state such as adhesive supply interruption, abnormal pressure, or excessive flow is detected in the main adhesive application device 10, a fault signal is automatically generated and transmitted to the control device 40. After receiving the fault signal, the control device 40 determines that the adhesive application system 100 needs to switch to the third operating mode and executes the control logic for the main and backup adhesive application devices 20 described above, so as to achieve seamless connection of adhesive application operations under fault conditions.

[0040] Continue to refer to Figure 2 and 3 The first glue supply assembly 13 is connected between the corresponding main glue tank 11 (e.g., the first main glue tank 11 and the second main glue tank 11) and the first distributor 12, and is used to deliver glue from the main glue tank 11 to the first distributor 12. Specifically, the first glue supply assembly 13 may include: a first glue pump for drawing glue from the first main glue tank 11, a second glue pump for drawing glue from the second main glue tank 11, a second distributor 15, and multiple glue supply pipelines (a second glue supply pipeline, a third glue supply pipeline, and a fourth glue supply pipeline 16).

[0041] The second glue supply line is connected between the first input end of the second distributor 15 and the output end of the first glue pump, and is used to transport the glue material from the first main glue tank 11 drawn by the first glue pump to the second distributor 15. The third glue supply line is connected between the second input end of the second distributor 15 and the output end of the second glue pump, and is used to transport the glue material from the second main glue tank 11 drawn by the second glue pump to the second distributor 15. The fourth glue supply line 16 is connected between the first output end of the second distributor 15 and the first input end of the first distributor 12, and is used to transport the glue material from the main glue tank 11 after switching or distributing by the second distributor 15 to the first distributor 12.

[0042] Furthermore, the second input end of the first distributor 12 is connected to the first glue supply line 30 (for receiving the glue material delivered by the standby glue application equipment 20), and the first output end of the first distributor 12 is connected to the first glue gun hose 14. Through the above connection relationship, the first distributor 12 can selectively receive the glue material from the main glue supply path (delivered via the second distributor 15) or the standby glue supply path (delivered via the first glue supply line 30), and distribute it to the first glue gun hose 14, and finally deliver it to the glue application end, providing a pathway basis for the glue application system 100 to switch between different operating modes.

[0043] The second glue supply assembly 23 is connected between the corresponding spare glue tank 21 (e.g., the first spare glue tank 21 and the second spare glue tank 21) and the multi-way valve device 22, and is used to achieve a stable glue delivery from the spare glue tank 21 to the multi-way valve device 22. Specifically, the second glue supply assembly 23 may include: a third glue pump for drawing glue from the first spare glue tank 21, a fourth glue pump for drawing glue from the second spare glue tank 21, a third distributor 25, and multiple glue supply pipelines (a fifth glue supply pipeline, a sixth glue supply pipeline, and a seventh glue supply pipeline 26).

[0044] The fifth glue supply line is connected between the first input terminal of the third distributor 25 and the output terminal of the third glue pump, and is used to transport the glue material from the first spare glue tank 21 drawn by the third glue pump to the third distributor 25. The sixth glue supply line is connected between the second input terminal of the third distributor 25 and the output terminal of the fourth glue pump, and is used to transport the glue material from the second spare glue tank 21 drawn by the fourth glue pump to the third distributor 25. The seventh glue supply line 26 is connected between the first output terminal of the third distributor 25 and the first input terminal of the multi-way valve device 22, and is used to transport the glue material from the spare glue tank 21 after switching or distributing by the third distributor 25 to the multi-way valve device 22.

[0045] Furthermore, the first output of the multi-way valve device 22 is connected to the second glue gun hose 24, and the second output is connected to the first glue supply line 30 (which in turn connects to the second input of the first distributor 12). In addition, the second output of the third distributor 25 can also be additionally connected to the third glue gun hose 27 (e.g., a redundant manual glue gun hose).

[0046] Through the modular component structure and pathway design described above, the glue application system 100 only requires simple additions to the existing glue application system 100 (such as adding a multi-way valve device 22, a first distributor 12, and corresponding pipelines) to achieve flexible distribution of glue between the main / backup equipment and different glue guns and hoses. This supports the first operating mode (backup glue supplies glue to the first glue gun hose 14), the second operating mode (main glue supplies glue to the first glue gun hose 14), and the third operating mode (backup glue supplies glue to the second glue gun hose 24) mentioned above. No disruptive modifications to the existing glue application system 100 are required, which significantly reduces the implementation cost and modification difficulty of multiple operating modes.

[0047] In some embodiments of the present invention, in order to ensure that the adhesive material is kept at a temperature that meets the requirements of the adhesive coating process during the conveying and dispensing process, and to avoid the adhesive material viscosity from increasing and fluidity from decreasing due to excessively low temperature, or the adhesive material from deteriorating due to excessively high temperature, the adhesive coating system 100 may also include a temperature control component for dispensing the corresponding dispenser, the corresponding valve device and the corresponding adhesive supply pipeline.

[0048] In some embodiments, the adhesive application system 100 may include at least one first heating element and at least one first temperature sensing element disposed on the first dispenser 12. The first heating element may be, for example, a heating resistor, a wound heating tape, or an embedded heating rod, and is uniformly arranged around the outer side of the housing and / or the internal cavity of the first dispenser 12 to provide stable heat to the adhesive within the first dispenser 12. The first temperature sensing element may be, for example, a thermocouple or a platinum resistance sensor, and is connected to the adhesive contact area or key parts of the housing of the first dispenser 12 to collect the actual temperature of the adhesive within the first dispenser 12 in real time. The first heating element and the first temperature sensing element may be communicatively connected to a control device 40. The control device 40 may automatically adjust the heating power of the first heating element based on the temperature signal fed back by the first temperature sensing element, maintaining the temperature of the adhesive within the first dispenser 12 within a preset process range, thus ensuring the accuracy of adhesive dispensing and the quality of adhesive application.

[0049] In some embodiments, the adhesive application system 100 may include at least one second heating element and at least one second temperature sensing element disposed on the multi-way valve device 22. The second heating element may be, for example, a heating resistor, an arc-shaped heating element, or a sleeve-type heater adapted to the valve body of the multi-way valve device 22, and is fitted and installed on the outside of the valve body of the multi-way valve device 22 to heat and maintain the temperature of the adhesive flowing inside the valve body. The second temperature sensing element is installed at the adhesive inlet end, outlet end, or middle of the valve body of the multi-way valve device 22 to monitor the temperature of the adhesive inside the valve body in real time. The second heating element and the second temperature sensing element can also be communicatively connected to the control device 40. Based on the detection data from the second temperature sensing element, the control device 40 dynamically adjusts the operating state of the second heating element to prevent blockage or performance changes of the adhesive within the multi-way valve device 22 due to temperature fluctuations, ensuring smooth adhesive delivery when the multi-way valve device 22 switches between different operating modes.

[0050] In some embodiments, the adhesive application system 100 may include a plurality of third heating elements and a plurality of third temperature sensing elements spaced apart from each other along the length of the first adhesive supply pipeline 30. Considering that the first adhesive supply pipeline 30 may have a long transport path, such as 5-10 meters, a single heating element may not be able to achieve uniform heating. Therefore, multiple third heating elements (such as heating resistors, wound heating tapes, or segmented heating sleeves) are evenly arranged along the length of the pipeline to ensure that the adhesive is heated uniformly throughout the pipeline. Correspondingly, the multiple third temperature sensing elements are arranged one-to-one with or spaced apart from the third heating elements to collect temperature data of the adhesive in different sections of the pipeline, preventing localized temperature runaway from affecting the adhesive's condition. The third heating element and the third temperature detection element can be connected to the control device 40. The control device 40 can independently adjust the third heating element of the corresponding section according to the feedback signal of the third temperature detection element of each section, so as to achieve precise control of the temperature of the adhesive material throughout the first glue supply pipeline 30. Especially when the spare adhesive material is transported to the first distributor 12 through the first glue supply pipeline 30 in the first operating mode, it can effectively ensure the temperature stability of the adhesive material from the multi-way valve device 22 to the first distributor 12, and further improve the consistency of the glue application process in multiple operating modes.

[0051] While specific embodiments of the present invention have been described in detail by way of example, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. The various embodiments disclosed herein can be combined in any way without departing from the spirit and scope of the present invention. Those skilled in the art should also understand that various modifications can be made to the embodiments without departing from the scope and spirit of the present invention.
