Multi-component proportional paint supply system and painting robot

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. 本发明公开了种多组分配比供漆系统以及喷漆机
