[0039] The utility model provides a glue feeding mechanism.

[0040] Please refer to Figs. 1-3 In an embodiment of the utility model, the glue feeding mechanism includes a glue feeding syringe 10, a glue feeding driving member 20 and a glue supplementing assembly 30, the glue feeding syringe 10 is used to load glue for dispensing, the glue feeding driving member 20 is in transmission connection with the glue feeding syringe 10 and is used to drive the glue feeding syringe 10 to discharge glue, and the glue supplementing assembly 30 is in communication with the glue feeding syringe 10 and is used to supplement glue for the glue feeding syringe 10.

[0041] The glue feeding syringe 10 is the core component of the glue feeding mechanism, and its main function is to load glue for dispensing. The syringe is usually made of materials resistant to chemical corrosion to accommodate different types of glue, including but not limited to epoxy resin, silicone, UV glue, etc. The design of the syringe needs to consider the viscosity, curing speed and usage of the glue to ensure stable and continuous glue flow during dispensing. The glue feeding driving member 20 is in transmission connection with the glue feeding syringe 10, and its main function is to drive the glue in the syringe to discharge outward. The driving member can be pneumatic, electric or mechanical, and the specific choice depends on the required dispensing accuracy, speed and properties of the glue. For example, a pneumatic driving member pushes the glue by the pressure of compressed air, while an electric driving member may use a stepper motor or a servo motor to accurately control the flow and speed of the glue. The glue supplementing assembly 30 is in communication with the glue feeding syringe 10, and its function is to supplement the syringe when the glue is used up without disassembling the syringe.

[0042] In the dispensing process, the glue supply driving member 20 drives the glue in the glue needle cylinder 10 to be discharged outward according to the preset program or the instruction of the operator. In this process, the glue supply driving member 20 needs to accurately control the flow and flow rate of the glue to ensure that the glue can be uniformly and continuously coated on the target surface.

[0043] When the glue in the glue needle cylinder 10 is about to run out, the glue supplement assembly 30 starts to work. The glue supplement assembly 30 is connected with an external glue supply source, and the glue supplement assembly 30 transports the glue from the supply source into the glue needle cylinder 10, so that the glue needle cylinder 10 always maintains a sufficient amount of glue, thereby avoiding dispensing interruption caused by insufficient glue.

[0044] The glue supplement assembly 30 is communicated with the glue needle cylinder 10, and the glue supplement assembly 30, the glue supply driving member 20 and the glue supplement assembly 30 are cooperated with each other. Since the glue supplement assembly 30 can supplement the glue without disassembling the needle cylinder, the glue supplement assembly 30 can supplement the glue of the glue supply cylinder without replacing the glue supply cylinder, so that the time required for replacing the glue is greatly reduced, and the glue supplement efficiency of the glue supply mechanism is improved. This is particularly important on a continuous production line, because it reduces the downtime caused by replacing the glue cylinder.

[0045] In an embodiment, referring to Figs. 1-3 The glue supply mechanism further comprises a communication pipe 40 communicated with the glue supplement assembly 30 and the glue needle cylinder 10.

[0046] The communication pipe 40 is a key component connecting the glue supplement assembly 30 and the glue needle cylinder 10, which ensures the smooth flow of the glue in the glue supplement process. The design of the communication pipe 40 needs to consider the viscosity and flowability of the glue to reduce the flow resistance and prevent the glue from solidifying in the pipe. The material selection of the communication pipe 40 also needs to be compatible with the chemical properties of the glue to avoid the reaction between the glue and the pipe material.

[0047] In the dispensing process, the glue supply driving member 20 drives the glue in the glue needle cylinder 10 to be discharged outward according to the preset program or the instruction of the operator. When the glue in the needle cylinder is about to run out, the glue supplement assembly 30 starts to work, obtains the glue from the external glue supply source, and transports the glue into the glue needle cylinder 10 through the communication pipe 40.

[0048] The communication pipe 40 plays a crucial role in the glue supplement assembly 30, which not only ensures the continuity and stability of the glue supplement process, but also significantly improves the glue supplement efficiency and accuracy. Through the communication pipe 40, the glue supplement assembly 30 can be seamlessly connected with the glue needle cylinder 10 to realize the rapid supplement of the glue, thereby reducing the production downtime caused by replacing the glue cylinder.

[0049] In an embodiment, referring to Figs. 1-3The glue supply mechanism further includes a three-way switch valve 50 installed in the communication pipe 40 for controlling the glue in the communication pipe 40.

[0050] The three-way switch valve 50 is a fluid control device installed in the communication pipe 40 for controlling the flow direction and flow rate of the glue. This valve has three ports: one inlet and two outlets, or two inlets and one outlet. By changing the passage inside the valve, the switching of the glue flow direction can be achieved, thereby controlling whether the glue flows to the glue dispensing needle cylinder 10 or flows back to the glue storage container. The design of the three-way switch valve 50 allows quick and precise switching of the glue flow direction without the need for physical movement or replacement of pipes, which greatly improves the response speed of the system and the convenience of operation.

[0051] During the dispensing process, the glue dispensing drive 20 drives the glue in the glue dispensing needle cylinder 10 to be discharged outward according to the preset program or the operator's instruction. When it is necessary to replenish the glue, the glue replenishing assembly 30 is started to obtain glue from the external glue supply source. At this time, the three-way switch valve 50 plays a key role, which accurately controls whether the glue continues to flow to the glue dispensing head for dispensing work or is diverted to the glue replenishing assembly 30 for glue replenishment according to the demand of the system.

[0052] During the glue replenishing process, the three-way switch valve 50 guides the glue in the communication pipe 40 to the glue dispensing needle cylinder 10, ensuring that there is always enough amount of glue in the needle cylinder. Once the glue replenishing is completed, the three-way switch valve 50 quickly switches to guide the glue back to the glue dispensing head to continue the dispensing work. This quick switching capability ensures the continuity of the dispensing process and the stability of the glue supply.

[0053] The three-way switch valve 50 is set in the glue supply mechanism, which greatly improves the response speed and control accuracy of the dispensing system. The quick switching capability of the three-way switch valve 50 enables the system to seamlessly switch between dispensing and glue replenishing, reducing downtime caused by replacing glue cylinders or adjusting pipes. The three-way switch valve 50 enhances the flexibility and adaptability of the system. By precisely controlling the flow direction and flow rate of the glue, the system can adapt to different dispensing requirements and types of glue, thereby improving the versatility and application range of the equipment.

[0054] In an embodiment, referring to Figs. 1-3 The communication pipe 40 is provided with a glue outlet; the glue supply mechanism further includes an outlet switch valve 60 installed in the glue outlet for controlling the glue outlet amount of the communication pipe 40.

[0055] The outlet on-off valve 60 is a precision fluid control device installed at the glue outlet of the communication pipe 40, used to control the amount of glue flowing from the glue supply syringe 10 to the glue dispensing head. This valve can accurately adjust the opening degree according to the needs of the glue dispensing process, thereby controlling the flow of glue. The design of the outlet on-off valve 60 usually includes an adjustable valve core and a driving mechanism, the movement of the valve core can change the size of the fluid passage, and the driving mechanism can be manual, pneumatic or electric to adapt to different operation requirements and automation levels.

[0056] When glue needs to be replenished, the glue replenishing assembly 30 is activated to obtain glue from an external glue supply source. At this time, the three-way on-off valve 50 directs the glue to the glue supply syringe 10, and the outlet on-off valve 60 is temporarily closed or adjusted to the minimum flow to prevent glue from flowing out of the glue outlet during glue replenishment. After the glue replenishment is completed, the three-way on-off valve 50 switches back to the glue dispensing mode, and the outlet on-off valve 60 adjusts the opening degree according to the glue dispensing requirements to continue to control the outflow of glue. The outlet on-off valve 60 is provided in the glue supply mechanism to accurately control the glue flow at the glue outlet, and the outlet on-off valve 60 ensures uniform glue distribution, thereby improving the glue dispensing quality.

[0057] In an embodiment, referring to Figs. 1-3 , the glue replenishing assembly 30 includes a glue replenishing syringe 31 and a syringe adapter 32, one end of the glue replenishing syringe 31 is in communication with the glue supply syringe 10; the syringe adapter 32 is connected with the other end of the glue replenishing syringe 31, used to connect with the driving member to control the movement of glue in the glue replenishing syringe 31.

[0058] The glue replenishing syringe 31 is the core part of the glue replenishing assembly 30, one end of which is in communication with the glue supply syringe 10 for storing and transmitting glue. The design of the glue replenishing syringe 31 needs to consider the flowability of the glue and the efficiency of the glue replenishment, so it is usually made of materials resistant to chemical corrosion and with smooth inner wall to reduce the resistance of the glue during transmission. The capacity and shape of the glue replenishing syringe 31 are optimized according to the requirements of the glue dispensing operation to ensure that the glue can be replenished quickly and accurately.

[0059] The syringe adapter 32 is connected with the other end of the glue replenishing syringe 31, its main function is to connect with the driving member to control the movement of glue in the glue replenishing syringe 31. The design of the adapter needs to ensure the close fit with the glue replenishing syringe 31 and provide stable connection with the driving member. The syringe adapter 32 may contain a mechanical interface, a seal and possibly fluid control elements such as valves to accurately control the flow of glue.

[0060] During the replenishment process, the replenishment syringe 31 first receives glue through its end connected to the glue supply syringe 10. The syringe adapter 32 is connected to a drive, which pushes or pulls the glue within the replenishment syringe 31 according to the requirements of the dispensing system. During this process, the control elements (such as valves) within the syringe adapter 32 precisely regulate the flow of glue, ensuring that it flows from the replenishment syringe 31 to the glue supply syringe 10 at the predetermined flow rate and speed.

[0061] When the amount of glue within the glue supply syringe 10 reaches the predetermined level, the control elements within the syringe adapter 32 automatically adjust to reduce or stop the flow of glue, thereby avoiding over-replenishment. This process can be automatically completed by sensors and control systems or manually controlled by operators.

[0062] The direct connection between the replenishment syringe 31 and the glue supply syringe 10 ensures the rapidity and continuity of glue replenishment, reducing production interruptions caused by replacing glue cartridges. The close cooperation between the syringe adapter 32 and the drive provides precise control over the flow of glue, ensuring the stability and consistency of the replenishment process.

[0063] In an embodiment, referring to Figs. 1-3 , the syringe adapter 32 is also provided with a replenishment port that is in communication with the replenishment syringe 31; the glue replenishment assembly 30 further includes a replenishment tube that is detachably inserted into the replenishment port for replenishing glue within the replenishment syringe 31.

[0064] The replenishment tube is a key part of the glue replenishment assembly 30, which is a detachable tube designed to connect an external glue supply source to the interior of the replenishment syringe 31. One end of the replenishment tube is inserted into the replenishment port on the syringe adapter 32, and the other end is connected to the glue supply source. The replenishment tube is usually made of chemically resistant materials to accommodate different types of glue and ensure durability and reliability during the replenishment process. The design of the replenishment tube allows for quick insertion and removal, making it easy for operators to perform glue replenishment operations, while also facilitating maintenance and replacement.

[0065] During the replenishment process, the operator first connects one end of the replenishment tube to the external glue supply source and then inserts the other end into the replenishment port on the syringe adapter 32. During this process, the connection between the replenishment tube and the replenishment port needs to ensure airtightness to prevent glue leakage during transmission. Once the connection is complete, the external glue supply source begins to deliver glue into the replenishment syringe 31, and the replenishment tube plays a role in transporting the glue during this process.

[0066] When the amount of glue within the replenishment syringe 31 reaches the predetermined level, the operator can easily remove the replenishment tube from the replenishment port, completing the replenishment operation. The detachable design of the replenishment tube makes this process quick and does not require complex tools, greatly improving the efficiency and convenience of glue replenishment.

[0067] In an embodiment, referring to Figs. 1-3 , the glue filling assembly 30 also includes a sealing ring installed at the glue filling port and in elastic abutment with the outer wall of the glue filling tube.

[0068] The sealing ring is an annular elastic element installed at the glue filling port. Its main function is to form a tight elastic abutment with the outer wall of the glue filling tube when the glue filling tube is inserted, thereby preventing glue leakage during the glue filling process. The sealing ring is usually made of materials resistant to chemical corrosion, with good elasticity and wear resistance, such as rubber, silicone or polytetrafluoroethylene. This design not only ensures the sealing of the glue filling interface, but also allows the quick insertion and removal of the glue filling tube without affecting the sealing effect.

[0069] The sealing ring provides excellent sealing performance, ensuring that glue does not leak from the glue filling port during the glue filling process, which not only improves the efficiency of glue use, but also avoids environmental pollution and potential safety risks caused by leakage.

[0070] In an embodiment, referring to Figs. 1-3 , the glue supply driving member 20 includes a housing, a servo motor, a lead screw, and a sliding rod. The housing has an inner cavity; the servo motor is installed in the inner cavity; the lead screw is connected to the output shaft of the servo motor; and the sliding rod is slidingly connected to the lead screw and connected to the air plug of the glue syringe 10.

[0071] The housing is the main structure of the glue supply driving member 20, with an inner cavity for accommodating and protecting the internal servo motor and other components. The servo motor is installed in the inner cavity of the housing and is the power source of the glue supply driving member 20. It can accurately adjust the speed and angle according to the control signal, thereby achieving precise control of the glue flow. The lead screw is connected to the output shaft of the servo motor, converting the rotary motion of the servo motor into linear motion. The design of the lead screw needs to ensure high precision and low wear to achieve smooth and precise motion control. The sliding rod is slidingly connected to the lead screw and connected to the air plug of the glue syringe 10. The movement of the sliding rod directly controls the position of the air plug, thereby adjusting the pressure in the glue syringe 10 and the outflow of glue.

[0072] During the glue dispensing process, the servo motor rotates according to the instructions of the control system, driving the lead screw to rotate through the output shaft. The rotation of the lead screw makes the sliding rod slide along the axis of the lead screw, thereby pushing or pulling the air plug connected to it. The movement of the air plug changes the pressure in the glue syringe 10, thereby controlling the amount and speed of glue outflow. During this process, the precise control ability of the servo motor ensures the precise adjustment of the glue flow, and the precise cooperation of the lead screw and the sliding rod ensures the smoothness and repeatability of the movement.

[0073] The high precision control capability of the servo motor ensures precise regulation of the glue flow, meeting the needs of precise dispensing process. The precise cooperation of the lead screw and the slide rod provides smooth and highly repeatable motion control, reducing fluctuations and errors in the dispensing process. In addition, the compact design and durability of the entire glue supply drive 20 ensure long-term stable operation performance, reducing maintenance costs and failure rates.

[0074] In an embodiment, referring to Figs. 1-3 Figs. 1-3 , the glue supply mechanism further includes a liquid level sensor installed in the glue syringe 10 for detecting the glue level in the glue syringe 10.

[0075] The liquid level sensor is a sensor used to detect and measure the height of the liquid, which can monitor the glue level in the glue syringe 10 in real time. The liquid level sensor usually uses non-contact measurement technology, such as ultrasonic, capacitive or photoelectric sensing technology, to avoid direct contact with the glue, reducing pollution and maintenance requirements. This sensor can accurately detect changes in the glue level and convert this information into an electrical signal, which is transmitted to the control system.

[0076] The liquid level sensor can monitor the glue level in real time, ensuring timely alarm or automatic glue replenishment when the glue is insufficient, thereby avoiding production interruption due to glue depletion. The precise measurement capability of the liquid level sensor improves the accuracy and consistency of the dispensing operation, ensuring product quality. In addition, the non-contact measurement technology of the liquid level sensor reduces maintenance requirements and potential failure points, improving the reliability and durability of the system.

[0078] The dispensing equipment of the utility model realizes high efficiency and high precision of dispensing operation through its carefully designed structure and components. Stable rack structure ensures accurate positioning of dispensing head during operation, thereby improving the accuracy and repeatability of dispensing. The precise control capability of the glue supply mechanism ensures the continuity and stability of glue supply, reducing production interruption and quality problems caused by insufficient or excessive glue supply. In addition, the close cooperation between the dispensing head and the glue supply mechanism enables the dispensing equipment to adapt to different types of glue and variable dispensing requirements, enhancing the versatility and flexibility of the equipment.
