Description

Technical Field

[0001] This utility model belongs to the field of spraying technology, and specifically relates to a spraying mechanism. Background Technology

[0002] In the manufacturing of automotive parts and precision structural components, uniform and efficient spraying of product surfaces is a crucial process to ensure their appearance quality, corrosion resistance, and subsequent assembly reliability. Traditional spraying processes often employ handheld spray guns or single-point fixed nozzles to spray the workpiece area by area, resulting in problems such as low spraying efficiency, uneven coating thickness, excessive manual intervention, and poor consistency. This is especially true for complex structural components such as brackets with multiple holes or irregular curved surfaces, where achieving full coverage spraying in a single operation is extremely difficult.

[0003] Furthermore, after spraying, excessive paint mist or tiny droplets often remain on the workpiece surface. If not removed in time, these can easily form runs, particles, or stains during the curing process, affecting product yield. Although some existing technologies incorporate an air-blowing cleaning step after spraying, these typically use a separate air-blowing device, requiring additional positioning and step-by-step operation. This not only extends cycle time but may also lead to poor cleaning results due to mismatch between the air-blowing position and the spraying area, or even cause paint surface disturbance or secondary contamination. Utility Model Content

[0004] The purpose of this utility model is to solve the above-mentioned technical problems existing in the prior art and provide a spraying mechanism with a clever and reasonable structural design. By surrounding the main nozzle assembly with the air blowing component and forming an integrated fixed connection with the fixed bracket and the main nozzle assembly, a high degree of integration of spraying and blowing functions is achieved. After spraying is completed, the air blowing component can be started immediately, which greatly improves production efficiency and process continuity. The fixed bracket provides a stable installation foundation for the nozzle and air blowing component. Connecting the fixed bracket to the end effector of the robot is suitable for high-speed operation of automated production lines, which significantly improves spraying efficiency, process consistency and maintenance convenience.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A spraying mechanism includes a fixed bracket, a main nozzle assembly, and an air blowing assembly. The fixed bracket is connected to the end effector of a robot. The main nozzle assembly is fixedly mounted on the fixed bracket. The air blowing assembly is arranged around the main nozzle assembly and is fixedly connected to the fixed bracket and the nozzle assembly.

[0006] Furthermore, auxiliary nozzle assemblies are provided on both sides of the main nozzle assembly. The auxiliary nozzle assembly includes an auxiliary spraying strip and an auxiliary spray nozzle. The auxiliary spray nozzle is installed on the auxiliary spraying strip. The design of the auxiliary nozzle assembly expands the spraying coverage, reduces spraying dead corners, improves spraying effect and spraying quality, and makes the spraying operation more uniform and comprehensive, meeting the spraying needs of large areas or complex surfaces.

[0007] Furthermore, the auxiliary spraying strip is fixedly connected to the air blowing assembly via a connecting plate. The connecting plate is fixed to the auxiliary spraying strip and the air blowing assembly with screws to ensure a firm and stable connection. The screw fixing also facilitates actual disassembly and maintenance, improving the overall structural reliability.

[0008] Furthermore, the main nozzle assembly includes a main spray frame, main spray strips, and main spray nozzles. Main spray nozzles are installed on both the main spray frame and the main spray strips. Both the main spray frame and the main spray strips are fixedly connected to a fixed bracket. External inlets are provided on both the main spray frame and the main spray strips. Multiple main spray strips are installed on the main spray frame, and their corresponding ends are fixedly connected to form a main spray frame. In addition to the main spray frame, multiple independent main spray strips are also installed below it. Several main spray nozzles are installed on both the main spray frame and the main spray strips, forming a multi-angle, multi-point spray array. This allows for efficient and uniform spraying of the workpiece from multiple directions simultaneously. The external inlet design facilitates paint supply and connection to external pipelines.

[0009] Furthermore, both ends of the main spraying frame are fixedly connected to the air blowing assembly via connecting bracket one. Connecting bracket one securely connects the main spraying frame and the air blowing assembly, ensuring the overall structural stability and robustness, which is beneficial to improving the consistency of spraying accuracy and air blowing effect. Connecting bracket one is fixed to the main spraying frame and the air blowing assembly with screws to ensure connection strength and facilitate actual disassembly and maintenance.

[0010] Furthermore, a tooling fixing plate is provided on the top of the fixed bracket. The tooling fixing plate is provided with fixing holes and positioning slots. The tooling fixing plate can realize the connection between the entire mechanism and the robot end effector or other equipment. The design of fixing holes and positioning slots facilitates the installation and positioning process, and improves installation efficiency and accuracy.

[0011] Furthermore, the fixed bracket is equipped with a connecting rod, and both ends of the connecting rod are provided with connecting holes. The design of the connecting rod and the connecting holes at both ends provides good expandability for the mechanism, allowing the spraying mechanism to be easily connected to other components or equipment. The setting of the connecting holes provides a standardized connection method, simplifies the installation process, and also facilitates adjustment and expansion according to actual needs.

[0012] Furthermore, the air blowing assembly is formed by connecting several air blowing modules. Each air blowing module includes an air blowing mounting base and an air blowing pipe. The air blowing mounting base is provided with an air blowing pipe mounting port and an air blowing inlet. The air blowing pipe is installed on the air blowing pipe mounting port, and an air blowing connector is installed on the air blowing inlet. The air blowing connector is connected to an air source. The modular air blowing assembly can be assembled and adjusted according to actual needs, improving the adaptability and flexibility of the spraying mechanism. At the same time, it facilitates the maintenance and replacement of individual modules, greatly reducing maintenance costs and improving operational flexibility. The standardized design of the air blowing pipe and air blowing connector ensures the convenience and sealing of the air source connection, thereby guaranteeing the stability and reliability of the air blowing effect and helping to improve the spraying quality.

[0013] Furthermore, the corresponding ends of the air-blowing mounting seats on two adjacent air-blowing modules are fixedly connected by a second connecting bracket. The second connecting bracket securely connects the adjacent air-blowing modules, enhancing the overall structural strength and stability of the air-blowing assembly. This ensures the relative position stability between the modules during the air-blowing process, preventing deformation or displacement during long-term use. It also helps improve the uniformity and consistency of the air-blowing effect, thereby improving the coating quality and efficiency. The second connecting bracket is fixed to the air-blowing mounting seat with screws, ensuring a firm connection and facilitating disassembly and maintenance.

[0014] This utility model, by adopting the above-mentioned technical solution, has the following beneficial effects: This utility model features an ingenious and reasonable structural design.
