Fluid excess material collecting device and spraying robot

The invention provides a fluid excess material collecting device and a spraying robot. The fluid excess material collecting device is assembled on an actuator, the actuator is provided with a discharge port, the fluid excess material collecting device comprises a material bearing box and a transmission guide mechanism, the material bearing box is arranged on the actuator, the material bearing box is provided with an opening, the transmission guide mechanism is used for being assembled on the actuator in a sliding mode and being in transmission fit with the material bearing box, and the transmission guide mechanism is used for driving the material bearing box to be away from the opening under the action of external force or driving the material bearing box to extend to the opening to bear a fluid excess material flowing out of the discharging port when the external force disappears. According to the fluid excess material collecting device, when the coating operation is finished, the external force acting on th
