Metering device for coating paint

Abstract

The invention discloses a metering device for coating paint. The metering device comprises a paint inlet, a gear metering panel, a paint flow metering valve, a servo motor and a paint outlet. The paint inlet and the paint outlet are connected with the paint flow metering valve through pipelines correspondingly. The gear metering panel is arranged between the paint inlet and the paint flow metering valve, used for controlling paint flow output and driven to rotate through the servo motor. The servo motor is connected with a robot main system. The robot main system is connected with the paint flow metering valve. According to the metering device for coating the paint, the rotating speed of the servo motor is adjusted through the robot main system according to the output value of the paint flow metering valve and the preset paint output quantity, and the number of rotating circles of the gear metering panel is changed; and accordingly, the paint output quantity is precisely controlled, the product appearance quality is ensured, and meanwhile the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of automobile painting, in particular to a metering device for painting paint. Background technique [0002] With the continuous improvement of production technology in the automobile industry, customers' demand for product quality continues to increase, and the requirements for painted appearance parts are becoming increasingly stringent. The existing production technology and equipment can no longer meet customer product quality requirements 100%, and the company's production costs continue to increase. up, profits keep falling. [0003] At present, the metering equipment of the painting production robot relies on air pressure to control the metering valve. This simple control method has obvious defects, and the poor accuracy is mainly reflected in the following aspects: (1) The metering valve is controlled by air pressure. Under different conditions, the sensing of the metering valve is different, so...

Problems solved by technology

[0003] At present, the metering equipment of the painting production robot relies on air pressure to control the metering valve. This simple control method has obvious defects, and the poor accuracy is mainly reflected in the following aspects: (1) The metering valve is controlled by air pressure. Under different conditions, the sensing of the metering valve is different, so that the actual amount of paint given will change, and the appearance of the product will be defective. The defect rate is very high and cannot be controlled.

(2) Due to the inaccurate measurement of paint, the amount of paint used cannot be accurately controlled, resulting in an increase in the actual amount of paint used in production and an increase in production costs
