Multi-component proportional paint supply system and painting robot

Abstract

The invention discloses a multi-component proportional paint supply system and a painting robot. The multi-component proportional paint supply system comprises a control unit and also comprises at least two gear pumps corresponding to different coating components and a mixing device; every gear pump is communicated with the mixing device and is connected with a driving device for flow control; allthe driving devices are connected with the control unit; the control unit controls the different driving devices according to paint component ratios to drive the corresponding gear pumps so that painting components determined according to the ratios are injected into the mixing device; the mixing device mixes well the different paint components injected. The gear pumps of the multi-component proportional paint supply system are used to actively pump the paint components so that the ratio precision is high and stable, and are also sued for controlling painting flow so that system cost is reduced.

Description

technical field [0001] The invention relates to the field of automatic spraying, in particular to a multi-component distribution ratio paint supply system and a painting robot. Background technique [0002] In recent years, in the industrial production of spraying, two-component paints are often used. The two-component paints are often mixed in the following two ways in production. One is to manually use electronic scales according to the proportion of paint before spraying. Proportioning and mixing the paint, and then adding it to the spray gun for spraying work, this method increases the workload of the operation, and the proportioning paint is harmful to the human body. [0003] The other adopts a two-component proportioning system to solve the proportioning problem of two-component paint in the painting industry. For example, the paint is composed of the original paint of the first coating component and the curing agent of the second coating component. Before spraying, ...

Problems solved by technology

[0005] However, the gear flowmeter in the prior art is passively driven by the liquid pressure to achieve measurement, which is prone to jamming, resulting in inaccurate or impossible proportioning. When using it, the gear flowmeter needs to be disassembled and cleaned frequently, which is laborious

[0006] In addition, the mass flowmeter in the prior art is bulky and difficult to install on the robot arm, and the mass flowmeter makes the delivery pipeline longer after the components are mixed, which wastes paint during color change and cleaning, and the pipeline in the metering section will appear Deposits that are difficult to clean, causing metering errors

[0007] At the same time, when the spray flow of the two-component proportioning system is passively controlled, it is necessary to increase the cost of the flow control device on the spray device
