The color recognition end 3 is close to the coating being detected, while the end with the end cap 2 is away from the coating being detected. A coaxial optical lens 4 is provided on the handheld component 1. The coaxial optical lens 4 consists of a sensing surface 41, a fiber optic connector 42, and a cable 43.

[0062] The handheld component 1 is a cylindrical structure open at both ends, with one end being a large end. This large end is a ring-shaped structure protruding from the handheld component 1 and serves as the color recognition end 3. During detection, it adheres to the coating being inspected, forming a dark chamber with the coating to isolate ambient light and improve detection accuracy. The end of the handheld component 1 furthest from the coating being inspected is provided with an end cap 2, which has a switch 6 that activates the color recognition sensor 5.

[0063] The coaxial optical lens 4 includes a sensing surface 41 and an optical fiber connector 42 connected by a cable 43.

The switch 6 is pressed to activate the color recognition sensor 5. Light is transmitted to the excitation sensing surface 411 through the exciter interface 51, the first fiber optic connector 421, and the cable 43. The light shines on the coating to be detected through the excitation sensing surface 411. When the light shines on the surface of the coating to be detected, the coating to be detected will be reflected. The reflected light enters the receiving sensing surface 412 through the color recognition end 3, and then passes through the cable 43, the second fiber optic connector 422, and the receiver interface 52 to finally reach the color recognition sensor 5. The detected light signal is converted into an electrical signal. Then, the internal circuit of the color recognition sensor 5 converts the electrical signal into a digital signal to obtain a color signal. The industrial Ethernet network module in the communication control unit then receives and transmits the color signal.
