[0002] Welding is a common process in automobile body production, and after completion, a large amount of iron powder adheres to the interior of the vehicle body. To prevent contamination of the paint wash tank by this large amount of iron powder, vacuuming is required within the welding assembly line before the paint is electrophoretically coated. Traditional manual vacuuming involves two employees using handheld industrial vacuum cleaners to perform extensive vacuuming, primarily relying on manual cleaning of various locations within the vehicle.
[0003] Industrial robots are now used for automated vacuuming. When vacuuming the rear of a car, a suspended, inverted arrangement is often used to avoid interfering with the vehicle's transportation. When the vehicle is tall, the gantry and the corresponding robot need to be suspended higher. However, the robot's arm reach limits its ability to reach the underside of the car for vacuuming. Furthermore, due to the varying rear openings of different vehicles, a suspended, inverted arrangement can hinder the robot's ability to reach the vacuuming space. Utility Model Content

The two driving cylinders 804 are relatively arranged on the clamping frame 801, and the first driving cylinder 802 is located at the rear end of the second driving cylinder 804, that is, it passes through the second driving cylinder 804 and then the first driving cylinder 802 along the assembly line 1.

When the transport component 2 moves to the dust collection station 102, the transport component 2 touches the limit stop 835. After sensing that the transport component 2 is in place, the controller starts the second driving cylinder 804 to drive the clamping component 805 to rotate and clamp the transport component 2; when the dust collection is completed, the first driving cylinder 802 is retracted, and the first driving cylinder 802 drives the transmission plate 832 to rotate.

When the transport component 2 moves, the second driving cylinder 804 is retracted to allow the clamping block 852 to be located in the height-limited space, and to rotate around the clamping rotating seat 851 under the restriction of the height-limiting frame 854, thereby avoiding the movement of the transport component 2; when clamping, the second driving cylinder 804 is extended to allow the clamping block 852 to leave the height-limited space, and the clamping block 852 rotates around the clamping rotating seat 851 under the action of the gravity of the counterweight block 853, so that the clamping block 852 can abut against the transport component 2, and cooperate with the limiting component 803 to clamp the transport component 2.
