[0055] Working principle: When in use, the stamping part is placed on the suction cup 25, and the moving column 22 will automatically drop due to the gravity of the stamping part, and under the elastic force of the spring 26, the descending position of each moving column 22 is different, so that the suction cup 25 can better contact with the bottom surface of the stamping part. When the moving columns 22 are no longer descending, the vacuum generator 27 is started to form a negative pressure inside the suction cup 25, so that the stamping part is adsorbed and positioned. By starting the first motor 52, the first motor 52 drives the first threaded rod 51 to rotate, thereby driving the mounting frame 53 to move, and finally the detector 11 can move left and right. By starting the second motor 63, the second motor 63 drives the second threaded rod 62 to rotate, thereby driving the threaded block 64 to move, and finally the detector 11 can move forward and backward, and the up and down movement of the detector 11 is achieved by the telescopic member 7. , by starting the micro motor 83, the micro motor 83 drives the rotating shaft 82 to rotate, thereby driving the fixed plate 20 to rotate, thereby driving the detector 11 to rotate, realizing the angular deflection movement of the detector 11, and at the same time, it can drive the nozzle 93 to deflect at an angle, and by starting the air pump 91, the air pump 91 blows air to the cavity 94 through the second hose 92, and then sprays it from the nozzle 93 to blow air to the surface of the stamping part, and blow away the dust or foreign matter on the surface of the stamping part, so as to achieve the purpose of cleaning the stamping part, avoid dust from affecting the detection, and improve the quality of the finished product. The surface of the stamping part is scanned and detected by the detector 11, and the controller 18 transmits the data to the display, and compares it with the digital model of the stamping part in the display, so as to judge whether the stamping part has wrinkles and cracks, and judge whether its angle meets the requirements;
