At the same time, the temperature of the plasma beam is not high, belonging to low-temperature treatment, which will not cause other additional hazards and will not cause overburning resulting in carbonization of the product surface.

[0031] Specifically, when the plastic tailgate 11 needs to be primer-coated on the surface, first place the plastic tailgate 11 to be primer-coated on the primer coating assembly 1. Then, set the front-end mechanism 33 of the robot on the welding base 22. At this time, the primer brush head 334 in the front-end mechanism 33 of the robot is inserted into the wetting box 24 to soak the coating. Then, start the robot arm 32. The front end of the robot arm 32 holds and lifts the front-end mechanism 33 of the robot. The robot arm 32 drives the front-end mechanism 33 of the robot to move back and forth, left and right, up and down to primer-coat the plastic tailgate 11 on the primer coating assembly 1. At the same time, during the primer coating process, the plasma gun head 333 ionizes compressed air to produce a plasma beam that impacts the surface of the substrate at high speed, increasing the surface activity of the substrate to meet the requirement of a qualified dyne value, facilitating the primer coating. When the coating on the primer brush head 334 is insufficient, it is necessary to use the robot arm 32 to drive the primer brush head 334 into the wetting box 24 to soak the brush head.

[0032] Further, please refer to Figure 3 , the primer coating wetting placement table assembly 2 includes a column 21. A welding base 22 is provided on the top surface of the column 21.

[0037] Further, the plasma gun head 333 ionizes compressed air to produce a plasma beam that impacts the surface of the plastic tailgate 11 at high speed, increasing the surface activity to meet the requirement of a qualified dyne value.

[0038] In this embodiment, the plasma gun head 333 produces a plasma beam by ionizing compressed air, and the high-speed impact on the surface of the plastic tailgate 11 increases the surface activity to meet the qualified dyne value. At the same time, the temperature of the plasma beam is not high, which belongs to low-temperature treatment and will not cause other additional hazards, nor will it cause overburning and carbonization of the product surface.

[0039] Further, please refer to Figure 1 , the robot assembly 3 further includes a plasma transformer 34, and the plasma transformer 34 is used to isolate high-voltage and low-voltage circuits, reducing electromagnetic interference and noise.

[0041] The working principle and usage process of the present utility model: When it is necessary to apply a primer to the surface of the plastic tailgate 11, first place the plastic tailgate 11 to be primed on the primer general assembly 1, and then set the front-end mechanism 33 of the robot on the welding base 22. At this time, the primer brush head 334 in the front-end mechanism 33 of the robot is inserted into the wetting box 24 to wet the coating material. Then start the robot arm 32. The front end of the robot arm 32 holds and lifts the front-end mechanism 33 of the robot. The robot arm 32 drives the front-end mechanism 33 of the robot to move back and forth, left and right, up and down to apply primer to the plastic tailgate 11 on the primer general assembly 1. At the same time, during the primer application process, the plasma gun head 333 produces a plasma beam by ionizing compressed air, and the high-speed impact on the substrate surface increases the surface activity of the substrate to meet the qualified dyne value, facilitating the primer application. When the coating material on the primer brush head 334 is insufficient, it is necessary to use the robot arm 32 to drive the primer brush head 334 into the wetting box 24 to wet the brush head; use plasma for the surface treatment of the plastic tailgate 11. The plasma ionizes compressed air to produce a plasma beam that high-speed impacts the substrate surface to increase the surface activity of the substrate to meet the qualified dyne value; at the same time, the temperature of the plasma beam is not high, which belongs to low-temperature treatment and will not cause other additional hazards, nor will it cause overburning and carbonization of the product surface.
