Description

Technical Field

[0001] This utility model relates to the field of metal structure processing and manufacturing, and in particular to an automatic spraying production line. Background Technology

[0002] Spray coating is a processing technique that uses tools such as spray guns and disc atomizers to atomize paint and apply it to the surface of an object. It can be used for purposes such as protection, decoration, and camouflage, and can impart properties such as corrosion resistance, wear resistance, and aesthetic appeal to objects. Various methods exist, such as air spraying and electrostatic spraying, and it is widely used in the automotive, furniture, and construction industries.

[0003] Current spraying technologies largely rely on manual operation, requiring workers to manually transport workpieces and perform spraying. This is not only inefficient but also time-consuming. Manual spraying makes it difficult to accurately control the spraying position and thickness, easily leading to uneven spraying and errors, resulting in inconsistent product quality. Furthermore, prolonged exposure to harmful substances such as paint poses safety hazards to workers.

[0004] To address the above problems, an automated spraying production line is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an automatic spraying production line, which aims to improve the current situation where spraying technology relies mostly on manual labor. Workers need to manually transfer workpieces and spray them, which is inefficient, time-consuming, and makes it difficult to accurately control the position and thickness of the spraying, which can easily lead to uneven spraying, errors and omissions, resulting in inconsistent product quality. In addition, workers are exposed to harmful substances such as paint for a long time, which poses a safety hazard.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an automatic spraying production line, comprising two supports, a crane rail fixedly connected between the two supports, a spraying support frame fixedly connected to the outer side of the crane rail, two monorail cranes installed at the bottom of the crane rail, workpieces placed at the bottom of the monorail cranes, two spraying rails one arranged at the lower part of the spraying support frame, a spraying robot one arranged outside the spraying rail one, a spraying rail two arranged outside the spraying support frame, a spraying robot two arranged outside the spraying rail two, a drying component arranged on the right side of the spraying support frame, and a conveying component arranged below the supports.

[0007] As a further description of the above technical solution:

[0008] The drying assembly includes a drying rack, the left side of which is fixedly connected to the right side of the spraying support frame.

[0009] As a further description of the above technical solution:

[0010] The conveying assembly includes a conveying system one and a conveying system two. The conveying system one is located below the support on the left side, and the conveying system two is located below the support on the right side.

[0011] As a further description of the above technical solution:

[0012] The drying rack is fixedly connected to the outside of the crane slide rail.

[0013] As a further description of the above technical solution:

[0014] The conveying system is located below the crane slide rail.

[0015] This utility model has the following beneficial effects:

[0016] In this invention, the workpiece is transported to the bottom of the crane rail via a conveyor system 1. The monorail crane lifts the workpiece and moves it to the spraying area. A spraying robot 1 on the spraying support frame sprays the sides and top of the workpiece, while a second spraying robot sprays the bottom. After spraying is complete, the monorail crane lifts the workpiece to the drying rack on the right side for drying. Finally, the workpiece is output by a conveyor system 2 under the right support. This achieves an automated production line, reducing manual intervention and transfer time, significantly improving production efficiency, reducing workers' exposure to harmful substances such as paint, ensuring operational safety, and allowing for precise control of the spraying position and thickness. This ensures uniform spraying on all surfaces of the workpiece, avoids errors and omissions in manual spraying, and improves product quality consistency. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figure 1 - Figure 3 An embodiment of this utility model provides an automatic spraying production line, comprising two supports 12, with a crane slide rail 9 fixedly connected between the two supports 12. A spraying support frame 8 is fixedly connected to the outside of the crane slide rail 9. Two monorail cranes 2 are installed at the bottom of the crane slide rail 9, with workpieces 5 placed at the bottom of the monorail cranes 2. Two spraying slide rails 10 are arranged at the lower part of the spraying support frame 8. A spraying robot 3 is arranged on the outside of the spraying slide rails 10. A second spraying slide rail 11 is arranged on the outside of the spraying support frame 8. A second spraying robot 4 is arranged on the outside of the second spraying slide rail 11. A drying component is arranged on the right side of the spraying support frame 8, and a conveying component is arranged below the supports 12.

[0024] Specifically, bracket 12 supports the overall structure and provides a base for the installation of other components; crane rail 9 provides a moving track for monorail crane 2, enabling it to lift workpiece 5 and move it in different areas of the production line; spraying support frame 8 is used to install spraying rail 10, spraying rail 2 11 and spraying robot, providing support for spraying operations; monorail crane 2 is responsible for lifting and transporting workpiece 5, allowing it to flow through conveying, spraying, drying and other stages; spraying rail 10 and spraying rail 2 11 provide moving tracks for spraying robot 3 and spraying robot 4 respectively, facilitating the robots to adjust their positions to complete the spraying of different surfaces of workpiece 5; spraying robot 3 and spraying robot 4 work together to spray the sides, top and bottom of workpiece 5; drying component is used to dry the sprayed workpiece 5 to dry the paint film; conveying component is responsible for the input and output of workpiece 5, realizing the transfer of workpiece 5 at the beginning and end of the production line.

[0025] Reference Figure 1 - Figure 3 The drying assembly includes a drying rack 6, which is fixedly connected to the right side of the spraying support frame 8 on the left side. The conveying assembly includes a conveying system 1 and a conveying system 2 7. The conveying system 1 is located below the left support 12, and the conveying system 2 7 is located below the right support 12. The drying rack 6 is fixedly connected to the outside of the crane slide rail 9 on the outside, and the conveying system 1 is located below the crane slide rail 9.

[0026] Specifically, conveyor system 1 is used to transport workpiece 5 to below crane rail 9, serving as the initial input of workpiece 5 into the automatic spraying production line. Conveyor system 1 and conveyor system 2 consist of rollers (including drive and driven rollers and idlers), drive devices (motor, reducer, coupling), frame, tensioning devices (screw type, counterweight type, etc.), and control systems (controller, sensor, operator interface), etc. These components work together to achieve the function of conveying materials. Crane rail 9 provides a moving track for monorail crane 2, facilitating the transfer of workpiece 5 between different areas of the production line. Monorail crane 2 is responsible for lifting and transporting workpiece 5, allowing it to move between different processes such as conveying, spraying, and drying. The spraying support frame 8 is used to install the spraying slide rails and spraying robots, providing a support structure for the spraying operation. Spraying slide rail 10 and spraying slide rail 2 11 provide moving tracks for spraying robots 3 and 4, respectively, facilitating the robots to adjust their positions to complete the spraying of each side of the workpiece 5. Spraying robots 3 and 4 work separately to spray the sides, top, and bottom of the workpiece 5. The drying rack 6 is connected to the right side of the spraying support frame 8 and to the outside of the crane slide rail 9 on the left side. It is used to receive the sprayed workpiece 5 and dry it through the internal drying components to cure the paint film. The conveying system 2 7 is located below the right support 12 and is used to output the dried workpiece 5 from the production line, completing the entire spraying process.

[0027] Working principle: First, the workpiece 5 is transported by the conveyor system 1 located below the left support 12. When the workpiece 5 enters the area below the crane slide rail 9 between the two supports 12, that is, the working range of the monorail crane 2, the two monorail cranes 2 installed at the bottom of the crane slide rail 9 will lift the workpiece 5.

[0028] Next, the monorail crane 2 lifts the workpiece 5 and moves it to the spraying area formed by the spraying support frame 8. At this time, the spraying robot 3 on the outside of the two spraying slide rails 10 at the bottom of the spraying support frame 8 and the spraying robot 4 on the outside of the spraying slide rail 11 on the outside of the spraying support frame 8 start to work. The two spraying robots 3 spray the sides and top of the workpiece 5. At the same time, the spraying robot 4, which is specifically responsible for bottom spraying, sprays the bottom of the workpiece 5.

[0029] After all surfaces of workpiece 5 have been coated, monorail crane 2 lifts workpiece 5 to drying rack 6 located on the right side of coating support frame 8. Drying rack 6 forms a drying assembly to dry workpiece 5 and promote paint film drying.

[0030] Finally, after the workpiece 5 is dried and the paint film is dry, the conveyor system 2 7 located below the right support 12 will output the workpiece 5, thus completing the entire automatic spraying production process.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
