[0019] A control panel 7 is provided at the front side of the visual inspection mechanism 6, and the internal signal of the control panel 7 is connected to a processor to ensure the effective execution of the rod conveying, cleaning and inspection processes.

[0020] The support mechanism 1 is provided with an inkjet mechanism 8 on one side close to the visual inspection mechanism 6, which is used for inkjet processing of the defective area on the rod. The inkjet mechanism 8 includes an inkjet bracket 801, a display host 802, and a nozzle 803. Fig.11 The display host 802 and the nozzle 803 are both installed on the inkjet bracket 801. The display host 802 is used to set the spray dosage, which is a common device and will not be described here. The nozzle 803 is set above the rod and can be used to perform inkjet treatment on the defects on the surface of the rod to facilitate users to identify the defect points.

[0021] In this embodiment, the chrome-plated rod to be tested is placed on the corresponding moving mechanism 3. In this description, the chrome-plated part is referred to as a rod. Usually, the size of the rod is in the range of 100 mm to 4000 mm. First, the rods placed on the moving mechanism 3 are sequentially conveyed toward the wind knife mechanism 4. During the conveying process, the first driving part 313 and the synchronous conveying member 309 are started. The output end rotation speed of the first driving part 313 determines the travel speed of the moving mechanism 3, and the output rotation speed of the synchronous conveying member 309 determines the rotation speed of the rods. Both can be adaptively adjusted through the settings at the control panel 7, and the applicability is high. When one of the moving mechanisms 3 drives the rod to move and passes under the wind knife mechanism 4, the second driving part 402 drives the dust removal tube body 411 that has been debugged in advance to move to a certain distance on the upper surface of the rod, and this distance can effectively perform a blow flow and impurity removal process on the surface of the rod. In addition, on the one hand, the air flow pressure blowing to the surface of the rod can be controlled by the operating power of the external first pump body or the fan, and on the other hand, the inner wall distance between the air flow grooves 412 can be adjusted by the fastener 413 to adjust the air flow pressure outflowing from the air flow port. For example, when it is known that the degree of dirt on the surface of the rod is high, the air flow pressure outflowing from the air flow port is increased by means of the external first pump body or the inner wall distance between the air flow grooves 412 is adjusted to ensure that the surface of the rod is effectively impurity-removed; When the primary impurity removal process is carried out at the wind knife mechanism 4, the rod maintains the original rotation state, and by setting up multiple dust removal tubes 411, the surface of the rod is subjected to a more comprehensive impurity removal treatment, and at the same time, the contact surface between the rod and the drum is also subjected to a corresponding degree of impurity removal treatment under the action of the airflow.

[0022] Afterwards, after the rod has completed the primary impurity removal treatment, the treated surface of the rod moves to the bottom of the cloth polishing mechanism 5, and the output end of the third drive unit 502 pre-adjusts the position of the cloth polishing disc 509 according to the diameter of the rod, so that the cloth polishing disc 509 can contact the surface of the rod and further remove impurities and clean the surface of the rod. In addition, the cloth polishing disc 509 rotates toward the air exhaust port 507, which is convenient for the air exhaust port 507 to collect the impurities cleaned by the cloth polishing disc 509, thereby improving the surface cleanliness of the rod and improving the accuracy of subsequent defect detection. Multiple cloth polishing discs 509 are arranged in the direction of the axial centerline of the rod, which also performs a more comprehensive impurity removal and cleaning treatment on the surface of the rod.

[0023] After completing the impurity removal process at the cloth polishing mechanism 5, the lens 610 first focuses on the shooting position. During the transmission and rotation of the rod, the side surface of the rod is photographed and recorded, and transmitted to the processor. The processor collects defects on the photographed side surface, and with the help of the pre-input recognition algorithm, the pits, scratches, cracks, abrasions and other defects on the surface of the rod are marked with different graphic blocks and colors. The recognition algorithm can also be continuously learned and updated based on the artificial intelligence algorithm to improve the accuracy of defect judgment.

[0024] The control panel 7 can retrieve the side surface mark image detected by the corresponding rod to obtain the defect data of the corresponding rod. In addition, the missed detection rate of the equipment can be fed back according to the measured defect data.

[0025] Finally, the inkjet mechanism 8 will perform inkjet processing on the corresponding position according to the defects marked on the above side circumferential surface, so as to inform the user of the defect position of the rod in a more intuitive way.

[0026] Through the setting of this online detection equipment, continuous conveying detection of multiple rods can be completed. In addition, multi-level cleaning treatment is carried out before detection to effectively improve the cleanliness of the surface of the rod to be tested, further improve the accuracy of defect detection, realize the integrated setting of cleaning and detection, improve the detection efficiency, and perform inkjet marking on the corresponding position after the defect position is obtained, so that users can intuitively and quickly obtain the position and number of defects on the rod surface and know the chrome plating condition of the corresponding rod.
