[0025] Working process:

[0026] First, input the distribution position of the detection head 1a of the flatness detector 1 into the control module of the CCD visual detection assembly. After the hydraulic processing of the belt pulley 9, the mechanical arm clamps the belt pulley 9 and sends it to the camera below for shooting, and then the mechanical arm transports the belt pulley 9 to the piece supporting table 7b.

[0027] In this process, the data transmission module transmits the photographed photo information of the belt pulley 9 to the control module of the CCD visual detection assembly, the control module compares the position information of the six ribs a on the belt pulley 9 in the photo with the distribution position information of the detection head 1a, and then transmits the comparison result to the mechanical arm. According to the comparison data, the control module controls the mechanical arm to place the belt pulley 9 on the piece supporting table 7b at the appropriate angle, so as to ensure that the positions of the six ribs a correspond to the distribution positions of the detection head of the flatness detector 1.

[0028] After the belt pulley 9 is placed on the piece supporting table 7b, the movable clamping jaw 7c clamps the belt pulley 9, and then the rotating cylinder is started to drive the rotating plate 7g to rotate, thereby driving the belt pulley 9 to the detection object placing table 1b side, and then releasing the belt pulley 9 to place it on the detection object placing table. Finally, the lower cylinder output drives the detection object placing table to rise, so that the belt pulley 9 contacts the detection head of the flatness detector 1, thereby performing the height detection work of the belt pulley friction plate.

[0029] If the detection head of the detector 1 can detect the signal, the flatness detector 1 sends a light signal to inform the worker that the belt pulley 9 is a qualified product. At the same time, the cylinder below the detection object placing table is retracted, and the worker places the qualified product on the qualified product conveying belt.

[0030] If the first measurement is not qualified, the output end of the telescopic cylinder 8 is extended to make the friction roller 8b contact with the outer circular surface of the belt pulley 9 on the detection object placing table, and then the rotary cylinder 8a is started to make the friction roller 8b rotate, thereby driving the belt pulley 9 to rotate horizontally by 60°, and then the output end of the telescopic cylinder 8 is withdrawn, and the detection object placing table is lifted for secondary detection. If the results of the two detections are still not qualified, the product is determined as unqualified,

[0031] The feeding assembly control module controls the movable clamping jaw and the rotary cylinder to work cooperatively to put the product back to the feeding station, and after the product is in place, the lifting cylinder lowers the clamping jaw to release the product, and sends a signal to the control module of the mechanical arm.

[0032] If the product is qualified, the mechanical arm clamps the product and puts it to the next detection process, and if the product is not qualified, the mechanical arm clamps the product and puts it into the NG conveying belt to flow out of the production line.
