1. A protective paint spraying equipment for a wheel hub, comprising:
a centering device, wherein the centering device is configured to center the wheel hub on the protective paint spraying equipment;
a paint spraying device, wherein the paint spraying device is configured to identify a horizontal position of a two-dimensional code on the wheel hub and spray the area of the two-dimensional code; and
a review device, wherein the review device is configured to identify the horizontal position of the two-dimensional code and a spraying position, and compare the horizontal position of the two-dimensional code with the spraying position,
wherein the paint spraying device comprises a first optical camera, and the first optical camera is configured to read the two-dimensional code and determine depth information of the two-dimensional code;
wherein the centering device comprises a fixing plate, an air cylinder on the fixing plate, a guide rail mounted on the fixing plate, a first centering slider and a second centering slider arranged in parallel on the guide rail, a symmetric connecting rod between the first centering slider and the second centering slider, a first synchronous connecting rod and a second synchronous connecting rod;
wherein a center of the symmetric connecting rod is hinged to the fixing plate, two ends of the symmetric connecting rod are hinged to a first end of the first synchronous connecting rod and a first end of the second synchronous connecting rod respectively, a second end of the first synchronous connecting rod is hinged to the first centering slider, a second end of the second synchronous connecting rod is hinged to the second centering slider, and an output end of the air cylinder is connected with the first centering slider or the second centering slider.
