[0027] The adjusting seat 201 and sliding seat 204 are both made of aluminum alloy. The adjusting seat 201 has an I-shaped structure design. The servo motor 211 and the drive screw 202, as well as the adjusting seat 201 and the slide table 5, are all fixedly connected. The guide pipe 206 and the air inlet pipe 210 are both made of polyethylene plastic hose. Multiple sets of protective nozzles 209 are provided.

At the same time, the controller 8 opens the solenoid valve 212, and the high-pressure gas in the air inlet pipe 210 flows into the guide tube 208 and is sprayed out along the protective nozzle 209. The sprayed airflow forms an air curtain to prevent the paint droplets sprayed by the automatic spray gun 205 from drifting towards the laser range sensor 207. After the spraying is completed, the controller 8 starts the air pump 6, which extracts the air from the spray box 1 and sends the extracted air into the waste liquid tank along the exhaust pipe 7. The controller 8 closes the solenoid valve 212, and the protective nozzle 209 no longer sprays high-pressure gas. The spray box 1 is opened and the plastic parts are taken out.
