The control system 5 adopts PLC and can be used with a human-machine interface for parameter adjustment.

[0030] The principle of the bridge support component detection of the utility model is:

[0031] Bridge support components such as upper support plates, spherical crowns, lower support plates, U-shaped steels, etc. are placed on the conveyor roller 1. The conveyor roller 1 is driven by a variable frequency motor or has its own power to move the component 6 to be inspected and transport it to the code reading system 2. The code reading system 2 identifies the QR code, barcode or engraving on the surface of the component, and feeds back the component name and coding information to the visual inspection system through the PLC for one-to-one inspection. Then the conveyor roller 1 transports the component to the area covered by the visual system 3 for online inspection.

[0032] The three-axis motion mechanism 3.2 of the visual system 3 drives the high-pixel camera and light source to move at a uniform speed along the surface of the component; a scanning surface is formed on the surface of the component, and whether the component is qualified is determined based on the scanning results. For components of different sizes, the camera detection distance can be adjusted through the three-axis motion mechanism. At the same time, the camera also has a zoom function to achieve accurate detection.

[0033] The qualified components are transported to the next process through the conveyor roller 1. At the same time, the control system will store and upload the information of the qualified components, and finally form an inspection report. The unqualified components can be prompted by the buzzer set on the control system 5, and the unqualified parts can be lifted to a certain height by the lifting mechanism 4 and manually removed through the side roller.

[0034] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited to this. Any changes or substitutions that can be easily thought of by technicians familiar with the field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in the field.
