Description

Technical Field

[0001] The utility model relates to the technical field of automobile sheet metal spraying, in particular to a spray gun for a painting robot. Background Technique

[0002] Automobile painting refers to applying a layer of paint to the surface of an automobile to achieve the effect of protecting the automobile. Automobile painting generally uses baking paint. In an automobile manufacturing factory, after the frame and car body are welded, the next process is painting. The forms include ordinary paint, metallic paint, and pearlescent paint. The automobile painting process: applying putty, sanding, painting, etc. Generally speaking, 90% of automobiles are made of steel. Without the protection of a paint coating, the lifespan of the automobile will be greatly reduced. The paint film can protect the beloved car from corrosion. With the advent of new materials, the role of paint film protection is becoming more and more important, such as high scratch resistance, elasticity, stain resistance, etc. At present, most of the automobile painting work in the market is carried out through a baking paint spray gun.

[0003] However, there are still certain deficiencies in the common baking paint spray guns on the market. Since the automobile has an arc-shaped structure, the spray gun needs to be adjusted at multiple angles. However, the spray gun and the kettle body on the existing market are generally in a corresponding vertical state. Therefore, when adjusting the angle, it is easy to cause the kettle body to contact the paint surface, affecting the paint surface effect. Based on this, there is an urgent need for an automatic spray gun for a painting robot in this field. Summary of the Utility Model

[0015] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0016] Embodiment:

[0017] Please refer to Figures 1-5, A spray gun for a painting robot, comprising a spray pot 1. One end of the spray pot 1 is communicated with a spray gun 4. One end of the spray gun 4 is fixedly connected with a rotating shaft 5. A cam follower 9 is installed on the outer surface of the rotating shaft 5. One side of the cam follower 9 is fixedly connected to the output end of a telescopic cylinder 3 through a rod body. The telescopic cylinder 3 is fixedly connected with a plate body 6 on one side of the spray pot 1. A cam guide groove 7 is opened on one side of the plate body 6. A follower roller bracket 8 is embedded in the cam guide groove 7. One side of the follower roller bracket 8 is connected with a driven rod. One side of the driven rod is installed on the rotating shaft 5 far away from the spray pot 1. A robot sub-quick change 2 is installed at the top of the telescopic cylinder 3. A connecting plate 12 is installed on one side of the robot sub-quick change 2. A second moving guide rail 11 is installed on one side of the connecting plate 12. A first moving guide rail 10 is installed on one side of the second moving guide rail 11. Through the cylinder and its auxiliary mechanism, the spray gun can adjust its posture at different angles during movement to achieve the best presentation of the paint surface. By placing an additional spray pot on the robot sub-quick change, the easy replacement effect of the spray pot can be achieved through setting. And through the inclined installation method between the spray pot and the spray gun, the contact between the spray pot and the paint surface is reduced.

[0018] A conical insert is fixedly connected to the bottom end of the robot sub-quick change 2. A groove body that fits the conical insert is provided at one end of the connecting plate 12. Based on this, the overall quick change effect is achieved.

[0019] In this embodiment, a resilient block 14 is fixedly connected to the outer surface of the rotating shaft 5. A spring 13 is fixedly connected to one side of the resilient block 14. One side of the spring 13 is fixed inside the cam follower 9. Through the resilience of this spring 13, it is convenient to realize the reset of the spray pot 1.

[0020] Working principle: During use, the connecting plate 12 is fixedly installed on the second moving guide rail 11. Through Figure 1 and Figure 5It can be seen that a conical insert is fixed at the bottom of the robot sub - quick change 2. One end of its connecting plate 12 is provided with a groove body that fits the conical insert, and the groove body is of an inclined surface structure, which is convenient for placing the conical insert. And one side of the groove body is open - ended. Therefore, after the conical insert is placed and sinks, it is automatically positioned, and the shape of the opening can prevent it from rotating left and right, achieving its stability. Based on this, the overall quick - change effect is realized. Among them, the spray bottle 1 and the spray gun 4 are rotationally locked through a quick - connection to realize the connected use of the spray bottle 1 and the spray gun 4, and the connection between the spray bottle 1 and the spray gun 4 is an inclined connection method. Then, by controlling the working of the telescopic cylinder 3, the working of the telescopic cylinder 3 is common general knowledge in the art, so it will not be elaborated here. Then, the telescopic cylinder 3 controls the cam follower 9 to move downward. During the downward movement of the cam follower 9, the rotating shaft 5 is driven to move downward. However, one end of the rotating shaft 5 is fixedly connected with a follower roller bracket 8, and the follower roller bracket 8 can only move inside the cam guide groove 7. Therefore, during the downward movement, the rotation of the rotating shaft 5 is realized to control the angle rotation of the spray gun 4. When the telescopic cylinder 3 pauses working, because the spring - back block 14 on the outer surface of the rotating shaft 5 is connected with the spring 13, the elasticity of the spring 13 forces the rotating shaft 5 to rotate, thereby controlling the telescopic cylinder 3 to reset, and at the same time controlling the spray gun 4 to reset.
