Description

Technical Field

[0001] The utility model relates to the technical field of automobile spray painting, in particular to a 2K varnish system controlled jointly by the inside and outside of a robot. Background Art

[0002] The paint surface of a car is divided into four layers in the traditional painting process, which together play a role in protecting and beautifying the car body. The outermost layer is varnish. The main function of varnish is to improve the gloss of the paint surface, enhance the texture, protect against UV rays, and prevent minor scratches, so there are relatively strict requirements on its hardness.

[0003] In the existing technology, an automated paint spraying system is often required to spray the varnish of automobile panels by robots. The paint spraying system can be divided into 1K, i.e., single component, and 2K, i.e., two-component. The 1K paint spraying system is simple to operate and has a single raw material structure. Even though the paint quality is not as good as the 2K paint spraying system, it has been widely used. However, with the market's increasing requirements for product paint quality in recent years, 1K varnish has been difficult to meet market demand. A large number of 1K paint spraying systems need to be converted to 2K paint spraying systems. The industry mainly adopts the following two solutions:

[0004] (1) Replace the 1K robot with a 2K robot;

[0005] (2) The 1K robot arm was replaced with a 2K robot arm, and the robot process control cabinet was updated simultaneously to add a curing agent corresponding valve assembly control; in addition, the robot control cabinet added a curing agent servo amplifier assembly and updated the 2K control software accordingly;

[0006] However, no matter which of the above solutions is adopted, it is necessary to re-purchase the entire 2K painting system and disassemble and assemble the robot, or even re-purchase the corresponding robot. The transformation period is very long and the transformation investment is huge. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Reference Figure 1 to Figure 2 The utility model provides a 2K varnish system controlled by the inside and outside of a robot, comprising: a main agent pipeline, a curing agent pipeline, a robot, a mixing module 10, a mixing tube and a pipeline fixing bracket, the main agent pipeline comprising a main agent color-changing valve 1, a main agent servo motor 3, and a main agent gear pump 4, one end of the main agent color-changing valve 1 is connected to a main agent raw material supply end, and the other end is connected to a main agent pressure regulator 2; the other end of the main agent pressure regulator 2 is connected to a main agent gear pump 4 driven by a main agent servo motor 3, the main agent gear pump 4 and the curing agent pipeline are connected in parallel to the mixing module 10, the other end of the mixing module 10 is connected to an atomizer 5 through a mixing tube, the atomizer 5 is located on the robot, and the mixing module 10 and the mixing tube are fixedly connected to the robot through a pipeline fixing bracket.

[0020] The curing agent pipeline includes a curing agent color-changing valve 6, a curing agent servo motor 8 and a curing agent gear pump 9. One end of the curing agent color-changing valve 6 is connected to the curing agent raw material supply end, and the other end is connected to the curing agent pressure regulator 7; the other end of the curing agent pressure regulator 7 is connected to the curing agent gear pump 9 driven by the curing agent servo motor 8, and the curing agent gear pump 9 and the main agent gear pump 4 are connected in parallel to the mixing module 10.

[0021] The curing agent gear pump 9 and the curing agent color-changing valve 6 are installed outside the paint spraying room and are controlled by an external PLC.

[0022] The robot is also equipped with a solvent cleaning pipeline and an air cleaning pipeline for cleaning the mixing module 10 and the mixing tube.

[0023] The PLC of the robot is equipped with both the 1K system and the 2K system, and the curing agent servo motor 8 on the curing agent gear pump 9 is controlled by the PLC of the robot to continue to maintain the 1K painting function.

[0024] The robot system can precisely adjust the flow rate and spraying position of the paint main agent by controlling the paint main agent, thus improving the uniformity and quality of the coating. At the same time, the PLC controls the curing agent so that the curing agent is mixed in proportion, ensuring the curing effect of the coating and enhancing its durability and corrosion resistance.

[0025] The biggest advantage of this improvement is that the robot controls the main agent and the PLC controls the curing agent, and only minimal system changes are required to achieve the transition from 1K to 2K. This means that there is no need to re-purchase and disassemble robots on a large scale, saving time and cost.

[0026] The robot controls the main agent and the PLC controls the curing agent, making the system operation more simplified and intuitive, reducing the technical requirements of the operator. At the same time, this division of labor makes the system more stable and reliable, reducing the risks that may be caused by operational errors.

[0027] This new control method makes it easier to upgrade technology. When the robot system needs to be upgraded or improved, only the PLC needs to be adjusted without having to readjust the robot's operating procedures.

[0028] Due to the separate control of the main agent and the curing agent, the system operation is more efficient and stable. This not only improves production efficiency, but also ensures the consistency and reliability of product quality.
