Description

Technical Field

[0001] This application relates to the field of glue dispensing machine technology, and in particular to a vacuum glue dispensing machine for precise metering and dispensing. Background Technology

[0002] In many industrial production fields, such as electronic component manufacturing, automotive parts packaging, and aerospace equipment production, the potting process plays a crucial role. As a key piece of equipment for achieving high-quality potting, the performance of the vacuum potting machine, which accurately measures and dispenses potting, directly affects the quality of products and production efficiency.

[0003] Some existing dispensing machines typically only allow dispensing at a fixed angle. When dealing with workpieces with complex shapes, it is difficult to achieve uniform coverage of the adhesive and adapt to diverse product needs. Furthermore, existing dispensing machines lack anti-drip designs. After dispensing stops, the adhesive inside the dispensing head cannot completely stop flowing due to gravity and the adhesive's own viscosity, causing the adhesive to slowly drip down from the dispensing nozzle. This dripping phenomenon not only contaminates the work platform and the surrounding environment but may also drip onto already dispensed workpieces, affecting product quality. Utility Model Content

The output end of the cylinder 7 passes through a through hole on the movable support frame 6 and is connected to a fixed frame 8. Two symmetrical guide rods are provided on the top of the fixed frame 8. One end of the two guide rods slides in a guide hole opened on the movable support frame 6. A drive shaft 9 is rotatably mounted in a shaft hole provided on the front side of the fixed frame 8. One end of the drive shaft 9 is located on the front side of the fixed frame 8 and is connected to a mounting frame 10. A dispensing head body 11 is mounted on the mounting frame 10. A rotating assembly for driving the dispensing head body 11 to adjust its angle is also provided on the fixed frame 8. The rotating assembly includes a drive motor 12 installed on one side wall of the fixed frame 8. The output end of the drive motor 12 passes through a through hole on the movable support frame 6 and is connected to a fixed frame 8. A through hole is opened on the side wall of the fixed frame 8, and a worm gear 13 is connected thereto. The other end of the worm gear 13 is connected to a bearing seat set on the other side wall of the fixed frame 8. The worm gear 13 also meshes with a turbine 14 installed on the other end of the drive shaft 9. More specifically, the fixed frame 8 is driven to move downward by the drive cylinder 7, so that the fixed frame 8 drives the dispensing head body 11 on the mounting frame 10 to move downward to the surface of the workpiece for dispensing. When dispensing a workpiece with a complex shape, the worm gear 13 connected to the output end is driven by the drive motor 12 to rotate, so that the worm gear 13 meshes with the turbine 14 installed on one end of the drive shaft 9 and rotates. This causes the drive shaft 9 to rotate and drive the dispensing head body 11 on the mounting frame 10 to rotate and adjust the angle, thereby enabling dispensing of workpieces with complex shapes and improving the quality and efficiency of dispensing.

[0015] refer to Figure 3 The heating assembly includes two symmetrical support rods 15 installed on both sides of the movable support frame 6 near the bottom. One end of each support rod 15 is connected to a heating cover 16, which covers the outside of the dispensing head body 11. A heating wire is installed inside the heating cover 16. More specifically, by providing symmetrical heating covers 16 on the outside of the dispensing head body 11, the heating wire inside the heating cover 16 can heat the dispensing head body 11 when it is not in use or when it has been in use for a long time, so that the dispensing liquid inside the dispensing head body 11 can be kept flowing, thus preventing the dispensing liquid from solidifying and causing blockage inside the dispensing head body 11.

The T-shaped slider 21 slides in a corresponding T-shaped groove 22 opened on one side of the mounting block 19. More specifically, by driving the electric push rod 18, the glue collection box 20 provided on one side of the mounting block 19 is moved to the bottom of the glue dispensing head body 11, so that the glue collection box 20 can collect the glue leaking in the gap of the glue dispensing nozzle of the glue dispensing head body 11, and prevent the glue from dripping and contaminating the workpiece or work platform.

[0017] The implementation principle of a vacuum dispensing machine for precise metering and dispensing according to an embodiment of this application is as follows: During use, the workpiece to be dispensed is placed on the moving table 5, which moves to the bottom of the dispensing head body 11 via the second slide rail 4. The electric push rod 18 drives the glue collection box 20 located on one side of the mounting block 19 to move to one side. Then, the cylinder 7 drives the fixed frame 8 downwards, causing the fixed frame 8 to move the dispensing head body 11 on the mounting frame 10 to the surface of the workpiece for dispensing. When dispensing workpieces with complex shapes, the drive motor 12 drives the worm gear 13 and the worm wheel 14 to mesh and rotate, causing the transmission... The rotating shaft 9 drives the dispensing head body 11 on the mounting bracket 10 to rotate and adjust the angle, thereby enabling dispensing of workpieces with complex shapes, improving the quality and efficiency of dispensing. When the dispensing head body 11 is not in use or has been idle for a long time, the heating wire inside the heating cover 16 keeps the glue inside the dispensing head body 11 flowing, preventing the glue from solidifying and causing blockage inside the dispensing head body 11. After the dispensing work is completed, the driving electric push rod 18 moves the glue collection box 20 to the bottom of the dispensing head body 11, thus preventing the glue inside the dispensing head body 11 from leaking and dripping, causing contamination to the workpiece or work platform.
