Embodiment 1

[0025] see figure 1 , the automotive exterior trim primer rotary cup spraying method comprises the following steps:

[0026] Ground the sled equipped with automotive exterior parts, and then fix the rotary cup atomizer 2 on the robot 1, and the robot 1 drives the rotary cup atomizer 2 to spray the primer to the surface of the automotive exterior parts; each robot 1 Control is performed through one control cabinet 3 , and each control cabinet 3 is controlled by a main PLC 4 .

[0027] The robot 1 used in this embodiment is an ABB spraying robot, and of course other robots can also be used. The robot 1 performs the spraying operation in the primer spray booth, and the main PLC 4 controls the walking track of the robot 1 in the spraying operation. The rotary cup atomizer 2 is fixed on the robot 1, and the automotive exterior parts are grounded, and the robot 1 drives the rotary cup atomizer 2 to spray the primer onto the surface of the automotive exterior parts.

Embodiment 2

[0032] see figure 2 In this embodiment, a high-voltage generator 6 is provided in the rotary cup atomizer 2, the electrostatic high voltage of the rotary cup atomizer 2 is 0-90kV, an intelligent voltage controller is installed in the robot 1, and the high voltage generation is controlled by the intelligent voltage controller Device 6. Using electrostatic adsorption, the atomized paint is charged and adsorbed to the surface of the product. In the rotary cup atomizer 2, there is also an integral air cap 5, the rotating cup head is arranged inside the integral air cap 5, and several compressed air channels are arranged around the rotating cup head on the shaping air cap, and the spraying width is installed in the robot 1. The air control system controls the size of the shaping airflow in the shaping air cap 5 through the spraying width air control system to spray the size of the width.

Abstract

The invention discloses a rotary cup spraying method for primer of an automobile exterior trimming part, and relates to the technical field of paint spraying. The rotary cup spraying method for the primer of the automobile exterior trimming part comprises the following steps that a skid provided with the automobile exterior trimming part is grounded, then a rotary cup atomizer is fixed to a robot, the robot drives the rotary cup atomizer, the rotary cup atomizer generates large centrifugal force through a cup head rotating at a high speed, high-viscosity paint is atomized, and then under the action of forming air, the atomized paint is pushed to the surface of the product; or, the electrostatic adsorption effect is added, so that the paint particles with charges are better adsorbed to the surface of the product after being atomized. Through the scheme, the thickness of a primer film of the product is greatly increased, the requirements of customers are met, the painting rate is increased to 50-70%, the paint mist amount of a spraying room is reduced, the appearance quality of the product is improved, meanwhile, consumption of the primer is reduced, and economic benefits are improved.

Description

technical field [0001] The invention relates to the technical field of paint spraying, in particular to a rotary cup spraying method for primers of automotive exterior trims. Background technique [0002] With the continuous increase of production demand and continuous improvement of product requirements, the traditional spray gun spray primer method for automotive exterior parts cannot meet the customer's requirements for perfect quality. [0003] In the spraying process, the paint rate of the spray gun spray primer method is far lower than that of the rotary cup spray primer method. Under normal circumstances, the paint rate of the spray gun is generally 20-30%. Therefore, when spraying with a spray gun, the thickness of the primer film of the product can only reach 5-10 μm, which is far below the 10-20 μm or 10-20 μm required by the customer. Other higher film thickness will have many adverse effects on the quality of future products. [0004] Since the spray gun adopts...
