[0050] Specific working principle:

[0051] After the injection molding production of the electric vehicle plastic part is completed, the edge of the electric vehicle plastic part needs to be polished. The worker adjusts the position of the adsorption positioning assembly 7 according to the size of the plastic part, so that the plastic part can be stably placed on the adsorption positioning assembly 7. The worker puts the cooled electric vehicle plastic part on the conveyor, and then the electric vehicle plastic part is conveyed to the side of the industrial robot 1 in sequence. The industrial robot 1 drives the rotating adsorption frame 4 to move to a position directly above the plastic part. The self-adaptive pressing adjusting device 3 pushes the rotating adsorption frame 4 to abut against the plastic part. The rotating adsorption frame 4 adsorbs and fixes the plastic part. The industrial robot 1 cooperates with the industrial camera to accurately drive the fixed plastic part to move to the adsorption positioning assembly 7. The adsorption positioning assembly 7 positions and fixes the placed plastic part. After the plastic part is placed in the specified position, the rotating adsorption frame 4 adjusts the position so that the rotating adaptive frame 5 and the flexible adsorption polishing device 6 are adjusted to the working position. The industrial robot 1 drives the flexible adsorption polishing device 6 to move to the edge of the plastic part. The self-adaptive pressing adjusting device 3 pushes the flexible adsorption polishing device 6 to descend. The self-adaptive pressing adjusting device 3 can effectively control the low pressure of the pushing pressure, so that the flexible adsorption polishing device 6 abuts against the edge of the plastic part. The polishing end of the flexible adsorption polishing device 6 uniformly polishes the burrs on the edge of the plastic part. The industrial robot 1 simultaneously drives the flexible adsorption polishing device 6 to move along the edge of the plastic part. The flexible adsorption polishing device 6 will encounter irregular edges when moving along the edge of the plastic part. The rotating adaptive frame 5 can be self-adaptively adjusted in angle to effectively improve the adaptability of movement, so as to ensure that the flexible adsorption polishing device 6 always maintains the center position of the edge of the plastic part and effectively improves the polishing effect. The flexible adsorption polishing device 6 cooperates with the adsorption positioning assembly 7 to effectively adsorb and polish the dust, thereby effectively ensuring the working environment.
