Description

Technical Field

[0001] This invention relates to the field of dispensing equipment, specifically to an adhesive processing device and method. Background Technology

[0002] With the emergence of new material combinations and the realization of more demanding designs, adhesive bonding has become a key manufacturing process in many industries, including aerospace, lighting, electrical, electronics, and automotive. In recent years, mature bonding methods such as bolting, welding, and riveting have increasingly become complementary to efficient adhesive bonding processes; in some cases, they have even been completely replaced. Adhesive bonding can connect parts without negatively impacting or damaging them like riveting or welding. For this reason, adhesive bonding is often called the "bonding technology of the new century." To achieve the unique electrical and physical properties of adhesives, special fillers are usually added to the resin, such as alumina, silver, or boron nitride. These fillers improve heat transfer between the two materials, thus preventing performance degradation and malfunctions. These fillers may be in the form of irregular fragments, spheres, or blocks, typically with very high hardness and sharp edges. Due to their density differences, they are very prone to settling and stratification within the adhesive cartridge. Once the adhesive settles and stratifies, it can lead to inaccurate dispensing, curing failure, and product scrap.

[0003] Therefore, it is necessary to provide an adhesive treatment device and a treatment method. Summary of the Invention

[0004] The present invention provides an adhesive processing device and method that effectively solves the problem of easy delamination and separation of existing adhesives.

[0005] The technical solution adopted in this invention is: an adhesive processing device, including an adhesive cylinder, a stirring mechanism disposed on the adhesive cylinder, the stirring mechanism being used to stir the adhesive in the adhesive cylinder, and further comprising, A feed pump, the inlet of which is connected to the bottom of the glue cylinder, is used to draw glue from the glue cylinder; A metering pump, the inlet of which is connected to the outlet of the feed pump via a feed pipeline, is used to dispense glue in a metered manner; A material valve, wherein the inlet of the material valve is connected to the outlet of the metering pump, the material valve has a reflux port, and its outlet is connected to the rubber cartridge; A reflux valve, integrated within the material valve, is used to control the opening and closing of the reflux port; A first pressure sensor is installed at the outlet of the feed pump to detect the outlet pressure of the feed pump. The second pressure sensor is installed at the inlet of the metering pump to detect the inlet pressure of the metering pump; The controller is electrically connected to the stirring mechanism inside the barrel, the feeding pump, the metering pump, the reflux valve, the first pressure sensor, and the second pressure sensor, respectively. The controller is configured such that, in the working state, it controls the reflux valve to close and the in-bucket stirring mechanism to start, so that the glue passes through the feed pump and the metering pump in sequence and is directly discharged to the outside from the outlet of the metering pump. At the same time, the in-bucket stirring mechanism performs internal circulation stirring of the glue in the glue cylinder. In the non-working state, it controls the reflux valve to open and controls the in-bucket stirring mechanism to start, so that the glue returns to the glue cylinder from the bottom of the glue cylinder through the reflux port of the feed pump, the metering pump, and the material valve, forming an external circulation. At the same time, the in-bucket stirring mechanism performs internal circulation stirring of the glue in the glue cylinder.

[0006] Furthermore, the rubber cylinder includes a bottom wall, a circumferential side wall, and a top wall. The stirring mechanism includes a drive motor mounted on the top wall, a spiral blade fixedly connected to the shaft of the drive motor, and an umbrella-shaped guide plate mounted on the upper end of the spiral blade. A fluid channel is provided between the umbrella-shaped guide plate and the spiral blade. The outer edge of the umbrella-shaped guide plate protrudes beyond the outer edge of the spiral blade. The umbrella surface of the umbrella-shaped guide plate slopes downward from the center to the edge, and its outer edge diameter is smaller than the inner diameter of the rubber cylinder, so that an annular channel is formed between the outer edge of the umbrella-shaped guide plate and the inner wall of the rubber cylinder.

[0007] Furthermore, it also includes a first hose and a second hose, wherein the outlet of the feed pump is connected to the inlet of the metering pump via the first hose; and the outlet of the metering pump is connected to the inlet of the material valve via the second hose.

[0008] Furthermore, the material valve integrates a manual valve for manually discharging glue, depressurizing the system, or urgently cutting off the glue passage. The material valve is also equipped with a first air inlet, a second air inlet, a third air inlet, and a fourth air inlet. The first and second air inlets are used to control the opening and closing of the return valve inside the material valve, and the third and fourth air inlets are used to control the opening and closing of the feed valve inside the material valve.

[0009] Furthermore, when the pressure value detected by the second pressure sensor is lower than a preset threshold, the feeding pump is started to feed material to the metering pump; when the pressure value detected by the second pressure sensor reaches or exceeds the preset threshold, the feeding pump stops feeding material, thereby realizing PID constant pressure closed-loop control.

[0010] Furthermore, in the aforementioned working state, the stirring mechanism inside the barrel continues to operate, the reflux valve remains closed, and the glue is only discharged from the outlet of the metering pump.

[0011] Furthermore, in the non-working state, both the stirring mechanism inside the barrel and the reflux valve remain open, and the glue continuously circulates between the glue cylinder, the feed pump, the metering pump, the material valve, and the glue cylinder until the working state is switched.

[0012] Furthermore, it also includes a buzzer. The first pressure sensor is used to monitor the working status of the feed pump and send the monitoring signal to the controller. The buzzer is controlled by the controller for feed pump fault diagnosis or alarm.

[0013] Furthermore, a spare material cylinder is also provided on one side of the material cylinder, and the spare material cylinder is connected to the glue cylinder pipeline.

[0014] A glue treatment method, based on the glue treatment equipment, includes an operating mode and a non-operating mode. In operation mode: close the reflux valve, start the stirring mechanism inside the barrel, so that the glue flows out from the bottom of the glue cylinder through the feed pump and metering pump, but keep the material valve inlet closed, so that the glue does not flow into the glue cylinder; at the same time, the stirring mechanism inside the barrel makes the glue circulate and stir internally. The stirring path is as follows: the glue rises from the bottom of the glue cylinder along the surface of the spiral blades to the top of the spiral blades, reaches the central area below the umbrella-shaped guide plate, and spreads outward under the guidance of the guide plate. It then flows down the inner wall of the barrel from the annular channel between the outer edge of the guide plate and the inner wall of the glue cylinder, and finally returns to the bottom of the glue cylinder below the glue surface. This cycle is repeated. In non-operating mode: Open the reflux valve and the in-bucket agitation mechanism to allow the glue to return from the bottom of the glue cylinder through the reflux port of the feed pump, metering pump, and material valve, forming an external circulation; at the same time, the glue is internally circulated and agitated in the glue cylinder by the in-bucket agitation mechanism, and its agitation path is the same as the in-bucket agitation path in operating mode.

[0015] Beneficial effects of the invention: This application uses a controller to intelligently switch between working and non-working states: in working state, the adhesive is directly dispensed without backflow; in non-working state, the backflow valve is opened, and the adhesive continuously circulates between the glue container, the feed pump, the metering pump, and the material valve. Combined with the in-bucket stirring mechanism, the adhesive remains in a flowing state whether during dispensing operations or standby, effectively preventing the sedimentation and stratification of high-density fillers, and avoiding inaccurate metering and curing failure.

[0016] The internal mixing mechanism uses spiral blades to lift the glue from the bottom upwards, where it spreads outwards after reaching the top umbrella-shaped guide plate. It then flows back to the bottom along the inner wall through the annular channel between the outer edge of the guide plate and the cylinder wall, forming a complete internal circulation path. This structure eliminates dead zones in the mixing process, forces the glue to mix repeatedly, and significantly improves the uniformity of the glue, making it particularly suitable for glues containing irregular, high-hardness fillers.

[0017] A second pressure sensor is installed at the inlet of the metering pump. The controller adjusts the operating state of the feed pump based on the pressure signal using a PID algorithm, keeping the inlet pressure of the metering pump constant. This closed-loop control eliminates pressure pulsations caused by changes in adhesive viscosity or fluctuations in material supply, ensuring the accuracy of the metering pump's dispensing, improving dispensing repeatability, and reducing product scrap rates.

[0018] The material valve integrates a return valve, a manual valve, and multiple air inlets, enabling both automatic pneumatic switching and manual valve operation for discharging adhesive, depressurizing, or emergency shut-off. Simultaneously, a primary pressure sensor at the feed pump outlet monitors the feeding status in real time, facilitating fault diagnosis and alarms. The overall design balances automated control with on-site emergency operation, enhancing system safety, ease of use, and maintenance convenience. Attached Figure Description

[0024] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0025] like Figure 1 , Figure 2 and Figure 3 As shown, the first embodiment provided in this application is an adhesive processing device, including an adhesive cylinder 1 and a stirring mechanism 2 disposed on the adhesive cylinder 1. The stirring mechanism 2 is used to stir the adhesive in the adhesive cylinder 1, and also includes... The feed pump 3 has its inlet connected to the bottom of the glue cylinder 1 and is used to draw glue from the glue cylinder 1. Metering pump 4, the inlet of which is connected to the outlet of feeding pump 3 through a feeding pipeline, is used to dispense glue in a quantitative manner; The material valve has an inlet that is connected to the outlet of the metering pump 4, and a reflux port. Its outlet is connected to the rubber cylinder 1. The reflux valve 6, integrated within the material valve, is used to control the opening and closing of the reflux port; The first pressure sensor 11 is located at the outlet of the feed pump 3 and is used to detect the outlet pressure of the feed pump 3. The second pressure sensor 12 is installed at the inlet of the metering pump 4 and is used to detect the inlet pressure of the metering pump 4. The controller is electrically connected to the stirring mechanism 2 inside the barrel, the feeding pump 3, the metering pump 4, the reflux valve 6, the first pressure sensor 11, and the second pressure sensor 12, respectively. The controller is configured such that, in the working state, the controller controls the reflux valve 6 to close and controls the in-bucket stirring mechanism 2 to start, so that the glue passes through the feed pump 3 and the metering pump 4 in sequence and is directly discharged to the outside from the outlet of the metering pump 4. At the same time, the in-bucket stirring mechanism 2 performs internal circulation stirring of the glue in the glue cylinder 1. In the non-working state, the controller controls the reflux valve 6 to open and controls the in-bucket stirring mechanism 2 to start, so that the glue returns to the glue cylinder 1 from the bottom of the glue cylinder 1 through the reflux port of the feed pump 3, the metering pump 4, and the material valve, forming an external circulation. At the same time, the in-bucket stirring mechanism 2 performs internal circulation stirring of the glue in the glue cylinder 1.

[0026] In the above design, the controller intelligently switches between working and non-working states. When working, it ensures that the glue is directly discharged without backflow. When in standby mode, it starts external circulation to prevent the glue from settling and separating. Combined with internal stirring, the glue is kept in a flowing state at all times, avoiding inaccurate metering and curing failure caused by filler settling, and improving the uniformity and metering stability of the glue.

[0027] Specifically: such as Figure 1 , Figure 2 and Figure 3 As shown, the glue cylinder 1 includes a bottom wall, a circumferential side wall, and a top wall. The stirring mechanism 2 includes a drive motor 21 mounted on the top wall, a spiral blade 22 fixedly connected to the shaft of the drive motor 21, and an umbrella-shaped guide plate 23 mounted on the upper end of the spiral blade 22. A fluid channel is provided between the umbrella-shaped guide plate 23 and the spiral blade 22. The outer edge of the umbrella-shaped guide plate protrudes beyond the outer edge of the spiral blade 22. The umbrella surface of the umbrella-shaped guide plate 23 slopes downward from the center to the edge, and its outer edge diameter is smaller than the inner diameter of the glue cylinder 1, so that an annular channel is formed between the outer edge of the umbrella-shaped guide plate 23 and the inner wall of the glue cylinder 1.

[0028] In actual use, the drive motor 21 drives the spiral blades 22 to rotate, lifting the glue at the bottom of the glue cylinder 1 upward along the spiral blades 22 and then flowing through the fluid channel to the top umbrella-shaped guide plate 23. Under the guidance of the guide plate, the glue spreads to all sides and flows down the cylinder wall back to the bottom through the annular channel between the outer edge of the guide plate and the inner wall of the glue cylinder 1, forming a complete upper and lower internal circulation.

[0029] In the above design, the spiral blades 22 of the stirring mechanism 2 cooperate with the umbrella-shaped guide plate 23 to make the glue produce orderly axial and radial mixing in the glue cylinder 1, without any dead corners in the stirring; the annular channel on the outer edge of the guide plate ensures that the glue is in uniform contact with the entire liquid surface, effectively inhibiting the rapid sedimentation of high-hardness fillers and significantly improving the uniformity of the glue during long-term storage and use.

[0030] Specifically: such as Figure 1 , Figure 2 and Figure 3 As shown, it also includes a first hose 7 and a second hose 8. The outlet of the feed pump 3 is connected to the inlet of the metering pump 4 via the first hose 7; the outlet of the metering pump 4 is connected to the inlet of the material valve via the second hose 8.

[0031] In the above design, the hose connection can absorb pump body vibration and installation errors, reduce pipeline stress, and facilitate equipment layout and maintenance; at the same time, it reduces pressure pulsation in glue flow, ensures stable material supply, and improves the stability of the inlet pressure of metering pump 4.

[0032] Specifically: such as Figure 1 and Figure 2 As shown, the material valve integrates a manual valve 9, which is used for manual glue discharge, system pressure relief, or emergency cut-off of glue passage; the material valve is also provided with a first air source inlet, a second air source inlet, a third air source inlet, and a fourth air source inlet; wherein, the first air source inlet and the second air source inlet are used to control the opening and closing of the return valve 6 inside the material valve, and the third air source inlet and the fourth air source inlet are used to control the opening and closing of the feed valve (built into the material valve) inside the material valve.

[0033] In the above design, manual valve 9 provides on-site emergency operation capability and enhances system safety; pneumatic control has fast response and high reliability, and can realize remote automatic switching, ensuring seamless transition between working and non-working states, and improving equipment usability and maintenance convenience.

[0034] Specifically: when the pressure value detected by the second pressure sensor 12 is lower than the preset threshold, the feeding pump 3 is started to feed the metering pump 4; when the pressure value detected by the second pressure sensor 12 reaches or exceeds the preset threshold, the feeding pump 3 stops feeding, thereby realizing PID constant pressure closed-loop control.

[0035] In the above design, PID constant pressure control ensures that the inlet pressure of metering pump 4 remains constant, eliminating metering errors caused by changes in glue viscosity or fluctuations in material supply; it improves the repeatability of the dispensing volume and reduces the risk of curing failure, making it particularly suitable for the precise metering of high-filler glues.

[0036] Specifically: In the working state, the stirring mechanism 2 inside the barrel runs continuously, the reflux valve 6 remains closed, and the glue is only discharged from the outlet of the metering pump 4.

[0037] In the above design, the return path is cut off during operation to ensure that all glue is used for dispensing, avoiding glue waste and pressure loss; at the same time, the stirring is not stopped to ensure that the glue in the glue container 1 is always uniform and does not affect the dispensing accuracy.

[0038] Specifically: In the non-working state, both the stirring mechanism 2 inside the barrel and the reflux valve 6 remain open, and the glue continues to circulate among the glue cylinder 1, the feed pump 3, the metering pump 4, the material valve and the glue cylinder 1 until the working state is switched.

[0039] In the above design, the glue flows through the return pipeline formed between the glue cylinder 1, the feed pump 3, the metering pump 4, the material valve, and the glue cylinder 1, enabling continuous circulation of the glue during standby. This effectively prevents the glue from settling in the pipeline and pump chamber. At the same time, the mixing inside the barrel remains uniform, allowing the equipment to quickly enter the working state at any time without additional pre-mixing or discharge, thus improving production efficiency and equipment utilization.

[0040] Specifically, it also includes a buzzer. The first pressure sensor 11 is used to monitor the working status of the feed pump 3 and send the monitoring signal to the controller. The buzzer is controlled by the controller for fault diagnosis or alarm of the feed pump 3.

[0041] In the above design, when the feed pump 3 fails, the first pressure sensor 11 senses the pressure inside the feed pump 3 to perform a diagnosis. Combined with a conventional buzzer, it can achieve automatic alarm and improve the early warning effect.

[0042] Specifically: a material preparation cylinder 10 is also provided on one side of the material cylinder, and the material preparation cylinder 10 is connected to the rubber cylinder 1 via a pipeline.

[0043] In actual use, the material is stored in the material preparation cylinder 10 and pumped to the rubber cylinder 1.

[0044] In the above design, the material preparation cylinder 10 is placed on one side of the glue cylinder 1 to facilitate the replenishment of glue to the glue cylinder 1.

[0045] like Figure 3 and Figure 4As shown, the second embodiment provided in this application is an adhesive treatment method, based on the adhesive treatment equipment, including an operating mode and a non-operating mode. In operation mode: close the reflux valve 6, start the stirring mechanism 2 inside the barrel, so that the glue flows out from the bottom of the glue cylinder 1 through the feed pump 3 and the metering pump 4 and then out of the outlet of the metering pump 4, but keep the material valve inlet closed so that the glue does not flow into the glue cylinder 1; at the same time, the stirring mechanism 2 inside the barrel makes the glue circulate and stir inside the glue cylinder 1. The stirring path is as follows: the glue rises from the bottom of the glue cylinder 1 along the surface of the spiral blade 22 to the top of the spiral blade 22, reaches the central area below the umbrella-shaped guide plate 23, and spreads to the surroundings under the guidance of the guide plate. It flows down the inner wall of the barrel from the annular channel between the outer edge of the guide plate and the inner wall of the glue cylinder 1, and finally returns to the bottom of the glue cylinder 1 below the glue surface. This cycle is repeated. In non-operating mode: Open the reflux valve 6 and the in-bucket stirring mechanism 2 to allow the glue to return from the bottom of the glue cylinder 1 through the feed pump 3, metering pump 4, and material valve reflux port to the glue cylinder 1, forming an external circulation; at the same time, the glue is internally circulated and stirred in the glue cylinder 1 by the in-bucket stirring mechanism 2, and its stirring path is the same as the in-bucket stirring path in the operating mode.

[0046] In the above design, the working mode and non-working mode are clearly divided. During the working mode, the glue is directly dispensed without affecting the mixing. During the non-working mode, the internal and external double circulation ensures that the glue does not settle. The specific mixing path inside the bucket makes the glue repeatedly experience the flow of "bottom → top → edge → bottom", which completely eliminates the stratification phenomenon of high-density filler and significantly improves the metering stability and dispensing quality.

[0047] In further detail, it should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
