Due to its high cost-effectiveness, wide applicability, ease of operation, and stable yield, it is widely recognized by the market and has great application prospects in the future.

[0003] Typically, glue cartridges are installed on the dispensing mechanism of high-speed dispensing equipment. During the dispensing process, the glue cartridges need to be replaced periodically to ensure sufficient glue. However, existing high-speed dispensing equipment usually uses manual glue replacement. To improve the replacement efficiency of glue cartridges, the inventor has designed an automatic glue cartridge replacement device that uses a gripping method to load and unload the glue cartridges to achieve automated replacement.

[0004] However, in the existing technology, there are still significant obstacles to the replacement of glue cartridges. For example, most glue cartridges still require tools or specific manual operations to disassemble and assemble during the replacement process. This makes it impossible to directly pick up and put down the glue cartridges on the dispensing mechanism, thus hindering the automated replacement of glue cartridges. Therefore, there is a need to provide a solution that facilitates efficient and convenient replacement of glue cartridges to overcome the above problems.

[0055] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0056] In the description of this utility model, it should be understood 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 that is centrally positioned therein. When a component is considered to be "set" on another component, it can be directly set on the other component or there may be a component that is centrally positioned therein.

[0057] Furthermore, terms such as "long," "short," "inner," and "outer" indicate orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings. They are used only for the convenience of describing this utility model and do not indicate or imply that the device or component referred to must have this specific orientation or operate in a specific orientational configuration. Therefore, they should not be construed as limitations of this utility model.

[0058] The following is in conjunction with the appendix Figure 1-6 The technical solution of this utility model will be further illustrated through specific implementation methods.

[0059] Example 1:

[0060] Please refer to Figure 1 This utility model provides a glue cartridge replacement mechanism, including a base 1, a dispensing valve 2, and a glue pressure assembly 3. The base 1 is typically mounted on the dispensing mechanism of a dispensing device. The dispensing mechanism can move the base 1. Simultaneously, the base 1 provides mounting positions for the dispensing valve 2 and the glue pressure assembly 3. During the displacement of the base 1, it can move components such as the dispensing valve 2, the glue pressure assembly 3, and the glue cartridge 7, thereby changing the dispensing position. In this embodiment, the base 1 is similar to a cuboid structure and is vertically arranged. The cuboid shape of the base 1 provides a larger and longer space, facilitating the assembly of various components.

[0061] At the same time, combined Figure 2 The dispensing valve 2 is fixedly connected to the base 1. The dispensing valve 2 has a plug-in module 21 with a dispensing channel. The plug-in module 21 is used to plug into the bottom end of the glue tube 7. When the glue tube 7 is plugged into the plug-in module 21, the dispensing channel is connected to the glue outlet at the bottom end of the glue tube 7. At this time, the glue in the glue tube 7 can enter the dispensing valve 2 through the dispensing channel. The dispensing valve 2 then drives the glue to spray out from the glue outlet to realize the dispensing action. Correspondingly, when the dispensing valve 2 is pulled out from the plug-in module 21, the bottom end of the dispensing valve 2 can be loosened, making it easy to disassemble and assemble the glue tube 7.

[0062] It is understood that the dispensing valve 2 provided in this embodiment is a piezoelectric dispensing valve 2, and the working principle of the dispensing valve 2 is prior art, which will not be described in detail here. In addition, the dispensing valve 2 can also adopt other general structures, and all dispensing valve 2 structures adopted should be included in the same scope of interpretation of this application.

[0063] In addition, to facilitate automated replacement of the glue cartridge 7, the glue pressure assembly 3 can be raised and lowered on the base 1, and the glue pressure assembly 3 is located above the dispensing valve 2. The glue pressure assembly 3 has an air inlet channel, which can be connected to an air pump. The air pump is used to pump air pressure into the glue cartridge 7 to cause the glue to flow out. In addition, the glue pressure assembly 3 is used to be movably connected to the top of the glue cartridge 7 so that the air inlet channel and the air inlet of the glue cartridge 7 can be connected or disconnected. When the two are connected, gas can be pressed into the glue cartridge 7 to provide glue supply pressure. When the two are disconnected, the top of the glue cartridge 7 can be loosened, making it easy to disassemble and assemble the glue cartridge 7.

[0064] The disassembly and assembly of the rubber sleeve 7 mainly includes the following two processes:

[0065] During the process of loading the glue cartridge 7 into the replacement mechanism, the glue pressure assembly 3 is first driven to rise, so as to obtain a larger loading space between the dispensing valve 2 and the glue pressure assembly 3. At this time, the external robot arm grabs the glue cartridge 7 and inserts the bottom end of the glue cartridge 7 into the plug-in module 21 of the dispensing valve 2. At this time, the bottom of the glue cartridge 7 is connected to the glue outlet channel on the dispensing valve 2, and the bottom end of the glue cartridge 7 is fixedly assembled. Subsequently, the glue pressure assembly 3 moves down and connects to the top end of the glue cartridge 7. On the one hand, the top end of the glue cartridge 7 is connected to the air pump to obtain glue supply pressure. On the other hand, the top end of the glue cartridge 7 is fixed, and the glue cartridge 7 realizes the automated assembly function.

[0066] Correspondingly, during the process of removing the glue tube 7 from the replacement mechanism, the external robotic arm first clamps the glue tube 7, and then the glue pressing assembly 3 loosens the top of the glue tube 7 and rises, providing more space for the glue tube 7 to move. At this time, the external robotic arm only needs to pull the bottom of the glue tube 7 out of the plug-in module 21 to remove the glue tube 7.

[0067] In summary, the technical solution provided in this application enables quick assembly and disassembly of the glue tube 7 by setting the bottom of the glue tube 7 to a plug-in connection and the top of the glue tube 7 to a lifting and pressing assembly. During this process, there is no need to manually disassemble the glue tube 7. It can be used with an automated robotic arm to meet the needs of automated assembly and disassembly, and the problem of inefficient and inconvenient replacement of the glue tube 7 is solved.

[0068] Reference Figure 3 To achieve positioning of the top of the glue cylinder 7, the glue pressing assembly 3 provided in this application embodiment includes a lifting component 31, a glue pressing quick-change valve 32, and an opening and closing component 33.

[0069] The lifting component 31 is mounted on the base 1 and is used to output vertical reciprocating motion. In addition, the quick-change rubber valve 32 and the opening and closing component 33 are respectively mounted on the lifting component 31. Under the action of the lifting component 31, the quick-change rubber valve 32 and the opening and closing component 33 can move up and down.

[0070] Furthermore, the quick-change valve 32 is mainly used for detachable connection with the top of the glue cylinder 7, and also for connection with an external air pump to achieve gas conduction. The opening and closing component 33 is used to open and close the quick-change valve 32, so that the quick-change valve 32 is fixed or loosened from the glue cylinder 7, thereby meeting the functional requirements of quick disassembly and assembly of the glue cylinder 7.

[0071] With the above configuration, the quick-change valve 32 can achieve quick connection between the glue cylinder 7 and the air pump. At the same time, with the cooperation of the quick-change valve 32 and the opening and closing component 33, it can also meet the requirement of quick disassembly and assembly of the top of the glue cylinder 7. The structure is reasonably designed and the components work together efficiently.

[0072] Furthermore, to achieve the lifting and displacement function, the lifting component 31 includes a lifting cylinder 311 and a sliding seat 312. The lifting cylinder 311 is fixedly mounted on the base 1, and its output shaft is vertically oriented. The sliding seat 312 is slidably mounted on the base 1. Typically, a slide rail and a slider can be configured between the sliding seat 312 and the base 1. The sliding engagement between the slider and the slide rail is achieved. No specific installation method for the sliding seat 312 is limited here; any method that enables sliding installation should be included within the scope of this application.

[0073] Meanwhile, the sliding seat 312 is connected to the output shaft of the lifting cylinder 311. Normally, the sliding seat 312 and the output shaft are fixedly connected to each other. Under the drive of the lifting cylinder 311, the sliding seat 312 can move up and down. In addition, the rubber quick-change valve 32 and the opening and closing component 33 are disposed on the sliding seat 312. During the sliding process of the sliding seat 312, the rubber quick-change valve 32 and the opening and closing component 33 can be driven to move up and down.

[0074] Furthermore, referring to Figure 4 To achieve communication between the air pump and the top of the rubber cartridge 7, the quick-change valve 32 in this embodiment includes a pressure valve body 321, a pressure buckle 322, and a pressure spring 323. The pressure valve body 321 is fixedly mounted on the sliding seat 312, and the air inlet channel is located on the pressure valve body 321. Specifically, interfaces are provided on the upper and lower sides of the pressure valve body 321, and the air inlet pipe passes through the valve body and the two interfaces sequentially. The lower interface is used to insert and cooperate with the top opening of the rubber cartridge 7, and the upper interface is used to connect to a flexible hose. The other end of the flexible hose is connected to the air outlet of the air pump, thus connecting the air inlet pipe to the air pump.

[0075] Meanwhile, two pressure buckles 322 are provided, which are rotatably mounted on the pressure valve body 321 and distributed on opposite sides of the pressure valve body 321. Specifically, in this embodiment, the pressure buckles 322 have a barbed structure, and a latching position is provided at the top of the glue cylinder 7 to engage with the pressure buckles 322. At this time, the pressure springs 323 are connected to the pressure valve body 321 and the pressure buckles 322 respectively. The pressure springs 323 are used to push the pressure buckles 322 to engage with the glue cylinder 7. It can be understood that there are also two pressure springs 323, and the two pressure springs 323 are respectively arranged in the two pressure buckles 322. The pressure buckles 322 cooperate with the opening and closing component 33, which is used to control the two pressure buckles 322 to move closer or further apart.

[0076] The specific working states of the opening and closing component 33 are as follows:

[0077] When the opening and closing component 33 is not working, the rubber spring 323 is in a naturally extended state, pushing the two rubber clips 322 to move closer to each other. At this time, the rubber clips 322 and the rubber cylinder 7 are in a snap-fit ​​state.

[0078] When the opening and closing component 33 is working, it drives the two rubber clips 322 to move away from each other. At this time, the spring is compressed and the rubber clips 322 are disengaged from the top of the rubber tube 7.

[0079] Furthermore, looking back Figure 3 To quickly and efficiently control the rubber clip 322 to move closer or further away, the opening and closing component 33 includes a finger cylinder 331 and opening and closing grippers 332. The finger cylinder 331 is fixedly installed in the lifting component 31. Specifically, the finger cylinder 331 is fixedly installed in the sliding seat 312 and has two output ends. Based on this, there are also two opening and closing grippers 332, which are respectively installed at the two output ends of the finger cylinder 331. The finger cylinder 331 is used to drive the opening and closing grippers 332 to move closer or further away. The opening and closing grippers 332 are used to press the rubber clip 322 to release the rubber clip 322 from the rubber cylinder 7. The action is quick, efficient, and easy to control.

[0080] Furthermore, looking back Figure 2 To enable quick assembly between the bottom of the glue cartridge 7 and the plug-in module 21, the plug-in module 21 is provided with a plug-in port 211 that communicates with the glue dispensing channel, and the outer periphery of the plug-in module 21 is provided with a snap-fit ​​boss 212.

[0081] Based on the above configuration, the insertion port 211 can be inserted and removed from the bottom of the glue tube 7 to achieve the effect of insertion and removal positioning. In addition, the snap-fit ​​boss 212 is used to snap into the bottom of the glue tube 7 to improve the connection stability and sealing between the dispensing valve 2 and the glue tube 7.

[0082] Optionally, to achieve the above-mentioned fastening effect, a structure similar to the aforementioned adhesive snap-fit ​​322 and adhesive spring 323 can be provided at the bottom of the glue tube 7. By engaging the snap-fit ​​with the fastening boss 212, the connection stability of the bottom end of the glue tube 7 can be improved. When it is necessary to loosen the bottom end of the glue tube 7, a clamping structure similar to the opening and closing component 33 can be provided on the external robotic arm. The specific fastening method of the glue tube 7 is not limited here. As long as a fastening method is adopted, it should be included in the scope of interpretation of this solution.

[0083] Furthermore, referring to Figure 3 The rubber sleeve replacement mechanism provided in this application also includes a Z-axis module 4, which can be a linear motor module, is vertically arranged, and the base 1 is set on the slide of the Z-axis module 4.

[0084] Using the above configuration, the Z-axis module 4 can drive the base 1, dispensing valve 2 and dispensing pressure assembly 3 to move up and down as a whole, thus achieving high-speed dispensing function.

[0085] Furthermore, the dispensing valve 2 is detachably connected to the base 1. In one embodiment provided in this example, the dispensing valve 2 is provided with a first quick-change disc 5, and the base 1 is provided with a second quick-change disc 6, the first quick-change disc 5 and the second quick-change disc 6 being detachably connected.

[0086] Based on the above settings, on the one hand, by making the dispensing valve 2 detachable, it is beneficial to replace and maintain the dispensing valve 2 regularly to maintain dispensing accuracy and precise dispensing volume; on the other hand, with the cooperation of the first quick-change disc 5 and the second quick-change disc 6, the dispensing valve 2 can be quickly replaced, with efficient and quick disassembly and assembly, and easy control, which can meet the automation requirements of the equipment.

[0087] Example 2:

[0088] Based on Embodiment 1, features not explained in this embodiment are explained using the methods described in Embodiment 1, and will not be repeated here. This embodiment provides a substitution kit, combined with... Figure 5 and Figure 6 The system includes the glue cartridge replacement mechanism of Embodiment 1, and also includes a glue cartridge 7, which includes a cartridge body 71 and a leak-proof valve 72. The leak-proof valve 72 is provided with an elastic buckle, which is movably engaged with the dispensing valve 2.

[0089] The cylinder 71 has a cylindrical structure, is hollow inside, and has openings at both ends for storing glue.

[0090] The leak-proof valve 72 is located at the bottom of the cylinder 71. The leak-proof valve 72 is used to control the flow of glue. The specific structure of the leak-proof valve 72 is similar to that of the quick-change glue pressure valve 32. It also has components such as valve body, buckle and spring. The valve body is also provided with an interface. For easy distinction, the above component features are defined as leak-proof valve body, leak-proof buckle and leak-proof spring respectively. The specific arrangement of the above components will not be described in detail here.

[0091] At this time, the leak-proof buckle and the leak-proof spring constitute the elastic buckle mentioned above. The elastic buckle is movably engaged with the fastening boss 212. During the assembly of the rubber tube 7, first press the elastic buckle to move it away from the leak-proof valve body, then insert the port of the leak-proof valve 72 into the insertion port 211, and then release the elastic buckle. The elastic buckle is then engaged with the fastening boss 212, thus achieving a fixed connection at the bottom of the rubber tube 7. The process is convenient, quick, and efficient.

[0092] In addition, the difference between the leak-stop valve 72 and the quick-change adhesive valve 32 also includes: the valve body is provided with an elastic valve core 721, and the adhesive outlet is located at the leak-stop valve body; the elastic valve core 721 is used to block the adhesive outlet, and the elastic valve core 721 will only be pushed open to achieve adhesive dispensing when the adhesive is subjected to adhesive supply pressure.

[0093] Therefore, the function of the elastic valve core 721 is to eliminate the glue supply pressure when the glue cartridge 7 is in the disassembled state, so that the residual glue in the glue cartridge 7 is not easy to flow out from the glue outlet, thus achieving the effect of preventing glue leakage.

[0094] In summary, a replacement kit for the 7-cell rubber tube, which is highly efficient and convenient, has been obtained.

[0095] Therefore, the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model 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 this utility model.
