In addition, if the surface of the door components is covered with dust, it can cause inaccurate 3D scanning. Furthermore, the 3D scanner is prone to overheating during long-term scanning, which can shorten its lifespan. Summary of the Invention

[0015] A method for detecting surface defects in new material components for new energy vehicles includes the following steps: S1.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) The present invention uses a base plate, clamping assembly, frame foot, housing, shaped part, gear shaft, rack, concave wide plate, servo motor, vertical frame and horizontal plate in conjunction with a three-dimensional scanner. The gear shaft drives the shaped part to move back and forth left and right. The shaped part slides back and forth left and right in two sliding grooves of the housing. The shaped part drives the vertical frame to move back and forth left and right. The vertical frame drives the horizontal plate to move back and forth left and right. The horizontal plate drives the three-dimensional scanner to move back and forth left and right. During the back and forth movement, the three-dimensional scanner scans the surface of the car door parts, so that it can reconstruct the three-dimensional model of the car door parts in the computer, and promptly detect the surface defects of the car door parts. This prevents the surface defect detection device from being incomplete in detecting long car door parts, which would cause the surface defect detection device to be ineffective.

[0017] (2) The present invention uses a dust blowing device to make the round tube, the U-shaped frame and the square shell cooperate with the partition. The square shell drives the partition to move back and forth. The air pump inputs gas into the square shell. The multiple grooves of the partition separate the gas and blow away the floating dust on the surface of the car door accessories, preventing the surface of the car door accessories from being covered with dust and causing inaccurate three-dimensional scanning.

[0018] (3) By setting up a dust blowing device, the present invention enables the horizontal plate and the U-shaped plate to work together with the spring. The U-shaped plate drives the spring to move back and forth. Under the compression force of the spring, the shaking of the horizontal plate when it moves left and right is reduced, and the 3D scanner on the horizontal plate is prevented from shaking violently, resulting in poor scanning effect of the 3D scanner.

[0019] (4) The present invention uses a cooling device to make the L-shaped vertical plate, the long box and the ring frame work together with the heat pipe. The long box drives the ring frame to move back and forth, and the ring frame drives the heat pipe to move back and forth. The heat pipe cools the surface of the three-dimensional scanner and prevents the three-dimensional scanner from overheating and shortening its service life.

[0020] (5) The present invention uses a cooling device to make the double arc plate and the L-shaped connecting plate work together with the tube plate. The L-shaped connecting plate drives the tube plate to move back and forth, and the tube plate supports the reciprocating frame to move back and forth, preventing the reciprocating frame from loosening during the movement and causing poor dust blowing effect of the device.
