Detailed Implementation

[0027] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0028] A specific embodiment of this utility model is as follows: Figure 1 As shown, an automatic glue application and edge sealing system for honeycomb panels is disclosed, including a motion unit 2, a glue supply unit 3, a glue mixing and edge sealing unit 4, and a control unit.

[0029] The glue mixing and edge sealing unit 4 is mounted on the motion unit 2, and the glue supply unit 3 is connected to the glue mixing and edge sealing unit 4; the control unit is electrically connected to the motion unit 2, the fixing unit 1, the glue supply unit 3, and the glue mixing and edge sealing unit 4.

[0030] Compared with the prior art, this embodiment includes a motion unit 2, an adhesive supply unit 3, an adhesive mixing and edge sealing unit 4, and a control unit. The control unit controls the motion unit 2, the adhesive supply unit 3, the adhesive mixing and edge sealing unit 4 to realize intelligent edge sealing of the composite sandwich panel 5, saving manpower and material resources, reducing labor intensity, improving production efficiency, and ensuring good product consistency.

[0031] Motion unit 2 drives edge-sealing structure 42 to fill materials of different shapes. Motion unit 2 is a three-axis gantry structure with X, Y, and Z axes, including a servo motor, linear guide rails, and ball screws. During operation, the control unit drives the servo motor to move the linear guide rails and ball screws, and the edge-sealing structure 42 moves to the edge-sealing position through the three-axis motion of X, Y, and Z axes. The linear guide rail and ball screw structure in this embodiment is prior art and will not be described in detail here.

[0032] Furthermore, it also includes a fixing unit 1. The fixing unit 1 includes a fixing platform 11, which is used to fix the composite sandwich panel 5. The fixing platform 11 is provided with multiple through holes 111, and a vacuum adsorption mechanism is provided below the fixing platform 11. The vacuum adsorption mechanism can adsorb and fix the composite sandwich panel 5 through the through holes 111.

[0033] In this embodiment, the fixing unit 1 includes a fixing platform 11, such as... Figure 2 As shown, a through hole 111 is provided on the fixed platform 11, and a vacuum adsorption mechanism is provided below it. The vacuum adsorption mechanism adsorbs and fixes the composite sandwich panel 5 on the fixed platform 11 through the through hole 111. The fixation is stable and uniform, protects the surface of the workpiece, and can adapt to various shapes and materials. It is highly adaptable and easy to operate.

[0034] The glue supply unit 3 is used for the storage and delivery of the glue, including a glue tank, a dispensing metering pump, a mold temperature controller, and a control valve. The glue tank is a cylinder piston tank used to hold and store the glue, and has functions such as pressure regulation, glue degassing, and uniform glue dispensing. The dispensing metering pump is a gear-type metering pump, which can control and adjust the single dispensing volume according to working conditions. The mold temperature controller is used to control the temperature at the glue inlet and the AB glue mixing position. The glue is connected to the dispensing metering pump and the mold temperature controller through pipes, and the control valve is located on the side of the mold temperature controller.

[0035] The adhesive mixing and edge sealing unit 4 is mounted on the motion unit 2 and connected to the adhesive supply unit 3 via a pipeline. The adhesive from the adhesive supply unit 3 is delivered to the adhesive mixing and edge sealing unit 4 for mixing and edge sealing. Figure 3 As shown, the glue mixing and sealing unit 4 includes a glue mixing structure 41, a sealing structure 42, a detection structure 43, and a temperature control mechanism 44.

[0036] The mixing structure 41 includes a mixing screw and a servo motor. The mixing screw is connected to the output shaft of the servo motor, and the servo motor drives the mixing screw to mix and stir the incoming adhesive. The control unit controls the stirring speed of the mixing screw by controlling the rotation speed of the servo motor, enabling continuous and efficient mixing. The mixing structure 41 also includes an inlet valve 46 for opening or closing the pipeline for conveying the adhesive.

[0037] The edge banding structure 42 includes an adhesive applicator, which is used to apply adhesive to the edges of the composite sandwich panel 5. The adhesive applicator has a hook-shaped structure, corresponding to the shape of the adhesive outlet. Under the control of a servo motor, it can work through gear transmission using an adhesive applicator rod, which can evenly and accurately apply adhesive to the edges of the composite sandwich panel 5, ensuring a good adhesion between the edge banding material and the sandwich panel and improving the edge banding quality.

[0038] The detection structure 43 includes an inlet pressure sensor 431 and an outlet pressure sensor 432, which respectively detect the pressure of the inlet and outlet adhesive layers to stabilize the adhesive thickness. The inlet pressure directly affects the amount of adhesive supplied, while the outlet pressure determines the actual amount of adhesive ultimately applied to the edge of the workpiece. By detecting the pressure values ​​of both sensors, it is possible to determine in real time whether the amount of adhesive meets the process requirements. By adjusting the pressure, the amount of adhesive can be kept stable, ensuring reliable bonding between the edge sealing material and the sandwich panel. Furthermore, it allows for timely detection of system anomalies, reducing the risk of failure.

[0039] The temperature control mechanism 44 is used to control the temperature of the colloid within the cavity of the mixing structure. The temperature is controlled by a constant-temperature water circuit from the mold temperature controller, which circulates water through the colloid supply cavity. Since the colloid is a temperature-sensitive substance, the temperature control mechanism 44 heats it to the optimal reaction temperature, ensuring that the colloid's flowability, viscosity, or cured strength meets the standards. If the temperature is too low, the colloid may not cure completely or have poor flowability, resulting in weak adhesion; if the temperature is too high, it may cause the colloid to age, decompose, lose its viscosity, or generate bubbles, affecting the sealing performance. Temperature fluctuations may cause dimensional deviations in the workpiece or adhesive layer due to thermal expansion and contraction. The temperature control mechanism 44 stabilizes the temperature, reducing the impact of thermal deformation on the product's dimensional accuracy and ensuring that the sealing fit and flatness meet the standards.

[0040] The visual recognition structure can identify and calibrate the position of the composite sandwich panel 5. For example, in this embodiment, the visual recognition structure is a vision camera. The edge-sealing structure 42 tightly fills the gaps between the sandwich panel skins with a paste-like adhesive. After curing, the visual recognition system detects the adhesive, and the algorithm software determines the detection result, realizing intelligent production and inspection of the entire system. Simultaneously, the visual recognition structure can also detect the fixed position of the composite sandwich panel 5 on the fixed platform 11.

[0041] Furthermore, it also includes a glue dispensing structure 45, which in this embodiment is a normal glue dispensing rotation mechanism. According to the board trajectory, the servo motor drives the glue applicator to maintain the normal glue dispensing state.

[0042] The control unit automates the fixing, glue supply, glue mixing, edge sealing, and movement processes. All board specifications are pre-stored in the control unit to provide data for automated control.

[0043] The adhesive mixing and sealing unit 4 in this embodiment includes an adhesive mixing structure 41, a sealing structure 42, a detection structure 43, and a temperature control mechanism 44. The adhesive mixing structure 41 uses an adhesive mixing screw. The detection structure 43 detects the glue inlet and outlet pressures to ensure accurate glue application and improve the sealing bonding quality. Through real-time monitoring and feedback adjustment, the stability and consistency of the sealing quality are guaranteed, while also improving the reliability and efficiency of the equipment operation. Since the adhesive is a temperature-sensitive substance, the temperature control mechanism 44 ensures stable adhesive quality and improves product quality.

[0044] The workflow of this embodiment is as follows:

[0045] The composite sandwich panel 5 is fixed to the fixed platform 11 by vacuum adsorption, and the position of the composite sandwich panel 5 is identified by a visual recognition structure. The glue supply unit 3 is started, and the glue inlet valve 46 is opened. The glue enters the glue mixing and edge sealing unit 4 through the pipeline. The control unit drives the motion unit 2 to transport the glue mixing and edge sealing unit 4 to the edge sealing position; the glue inlet detection sensor detects the glue inlet pressure, and the temperature control mechanism 44 controls the temperature of the glue in the cavity. After the required temperature is reached, the glue mixing screw stirs the glue under the drive of the servo motor; after the stirring reaches the required level, the glue is discharged through the normal glue discharge rotation mechanism, and the glue discharge pressure detection sensor 432 detects the glue discharge pressure; the glue enters the coating head and is coated and sealed under the drive of the motion unit 2.

[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
