They are generally formed by pressing, and their surface defects and dimensional accuracy affect the reliability of mechanical equipment. For example, the compression lines on the inner and outer sides of flexible graphite sealing rings are important objects that need to be detected. Traditional manual detection is inefficient, error-prone, time-consuming and labor-intensive, and the detection accuracy cannot be guaranteed. With the advancement of industrial technology, machine vision detection technology has the characteristics of high detection accuracy, high speed, and non-contact detection. Therefore, the method of combining machine vision technology with digital image processing technology is necessary and feasible.

The arc-shaped conductive rail 23 extends from the inner surface detection position 4 to the loading position 2, and the cylinder shaft 27 is equipped with a power connection component 26 electrically connected to the corresponding spring 34 and the corresponding first conductive head 22. When the barrel 8 rotates to the loading position 2 and the outer surface detection position 3, the corresponding first conductive head 22 rotates away from the arc-shaped conductive rail 23, the circuit is disconnected, and a pair of springs 34 are reset, and a pair of arc-shaped abutment plates 13 are driven by the abutment rod to abut against the inner walls on both sides of the flexible graphite sealing ring 14, thereby supporting the flexible graphite sealing ring 14 and maintaining the support state, so as to complete synchronous rotation with the barrel 8.

[0033] Side visual inspection cameras 9 are installed on both sides of the outer surface inspection position 3. A pair of side visual inspection cameras 9 are used to inspect the two side ring surfaces of the flexible graphite sealing ring 14. An outer visual inspection camera 12 for inspecting the outer side wall of the flexible graphite sealing ring 14 is installed on the top of the outer surface inspection position 3. A light blocking plate 15 extending from the outer surface inspection position 3 to the inner surface inspection position 4 is fixedly installed in the circular inspection box 1. The circumferential side walls of the inspection disk 6 are provided with inspection holes 25 corresponding to the four barrels 8 one by one. Inspection holes 25 are also provided on the light blocking plate 15 corresponding to the outer surface inspection position 3 and the inner surface inspection position 4. The light irradiated by a pair of side visual inspection cameras 9 passes through the corresponding inspection holes 25. A pair of side visual inspection cameras 9 photograph the two side ring surfaces of the flexible graphite sealing ring 14 through the corresponding inspection holes 25. The outer visual inspection camera 12 completes the inspection process of the circumferential outer side wall (compression lines and other defects).

[0034] Clamping assemblies for clamping the flexible graphite sealing ring 14 are installed on both sides of the inner surface detection position 4. The clamping assemblies include clamping cylinders 11 fixedly installed on both sides of the inner surface detection position 4. The telescopic ends of the clamping cylinders 11 pass through the detection holes 25 at the corresponding positions and clamp the flexible graphite sealing ring 14. After the flexible graphite sealing ring 14 is transferred to the inner surface detection position 4, a pair of clamping cylinders 11 are started, pass through the corresponding detection holes 25 and clamp the flexible graphite sealing ring 14, so that the flexible graphite sealing ring 14 does not rotate synchronously with the barrel 8.

[0035] A mounting block 31 is fixedly installed in the middle of the barrel 8, and an L-shaped detection channel 28 is arranged in the mounting block 31. The radial end of the L-shaped detection channel 28 is connected to the barrel wall of the barrel 8, and a docking channel 32 is docked at the axial end of the L-shaped detection channel 28.

The docking ring 39 is adapted to the channel opening of the docking channel 32. The side wall of the light shielding plate 15 is provided with a docking port for the detection tube 37 to pass through. The docking cylinder 10 is started to drive the detection tube 37 to pass through the docking port, and the docking ring 39 abuts against the docking channel 32. The inner visual inspection camera can capture the inner wall through the reflector 30. With the rotation of the barrel 8, the entire inner wall (compression marks and other defects) inspection process can be completed.

[0036] Furthermore, a plurality of fill lights 29 are embedded in the barrel wall on both sides of the L-shaped detection channel 28 of the barrel 8, and four second conductive heads 36 corresponding to the barrel 8 are fixed on the circumferential side walls of the detection disk 6. The power connection component 26 electrically connects the corresponding second conductive heads 36 and the fill lights 29. A conductive seat 35 matching the second conductive head 36 is installed on the inner surface detection position 4. The second conductive head 36 contacts the conductive seat 35, and power is supplied to the plurality of fill lights 29 through the power connection component 26. The light emitted by the fill lights 29 evenly irradiates the inner wall of the flexible graphite sealing ring 14, thereby improving the quality of photographs taken and improving the detection effect.

[0037] The above-mentioned power connection component 26 includes a conductive ring and a brush. The conductive ring is sleeved on the cylindrical shaft 27. The brush is installed on the rear side of the detection disk 6 and contacts the corresponding conductive ring. The conductive ring is electrically connected to the fill light 29 and the spring 34. The brush is electrically connected to the first conductive head 22 and the second conductive head 36 to maintain the power-on state during the rotation process.

[0038] A unloading cylinder 17 is fixedly installed on the rear side of the unloading position 5. The circumferential side wall of the detection disk 6 is provided with unloading ports 24 corresponding to the four barrels 8 one by one. The unloading ports 24 are for the telescopic end of the unloading cylinder 17 to pass through. The clamping assembly releases the flexible graphite sealing ring 14 and continues to rotate to the unloading position 5. The unloading cylinder 17 is started and the flexible graphite sealing ring 14 after detection is pushed out through the unloading port 24 for automatic unloading.

[0039] A self-rotation mechanism that can synchronously drive multiple barrels 8 to rotate synchronously is also installed on the rear side of the circular detection box 1. The self-rotation mechanism includes a barrel shaft 27 fixedly connected to the rear end of the barrel 8, and a driven gear 19 is fixedly connected to the barrel shaft 27. The rear side of the detection disk 6 is rotatably connected to an outer gear ring 20 that meshes with multiple driven gears 19, and an inner gear ring is fixed to the inner wall of the outer gear ring 20. A motor 18 is installed on the rear side of the circular detection box 1, and the output shaft of the motor 18 is fixedly connected to a driving gear 21 that meshes with the inner gear ring. The motor 18 is started, and the inner gear ring is driven to rotate through the driving gear 21, and then the driven gear 19 is driven to rotate through the outer gear ring 20, and the barrel 8 is driven to rotate through the barrel shaft 27, and then the flexible graphite sealing ring 14 in the supporting state is driven to rotate, and the outer and inner surface detection processes can be carried out synchronously, and the detection efficiency is high.

[0040] The flexible graphite sealing ring 14 is clamped by a robot and loaded on the barrel 8 at the loading position 2. The detection disk 6 can be driven to rotate by the driving shaft 16, and then turn to the outer surface detection position 3 and the inner surface detection position 4 in turn. The comprehensive detection process of the surface quality of the flexible graphite sealing ring 14 can be completed in two times. The first time, the detection process of the ring surface on both sides and the circumferential outer wall is completed synchronously, and the second time, the detection process of the circumferential inner wall is completed, and the detection is comprehensive.

[0041] After the flexible graphite sealing ring 14 is fed into the barrel 8 in front of the loading position 2 by the manipulator, the detection disk 6 drives the corresponding barrel 8 to rotate. When the corresponding first conductive head 22 turns away from the arc-shaped conductive rail 23, the circuit is disconnected, and a pair of springs 34 are reset. The arc-shaped plates 13 are driven by the abutment rod to abut against the inner walls on both sides of the flexible graphite sealing ring 14, supporting the flexible graphite sealing ring 14, and rotating to the outer surface detection position 3 in a supported state. A pair of side visual detection cameras 9 shoot the ring surfaces on both sides of the flexible graphite sealing ring 14 through the corresponding detection holes 25. At the same time, the motor 18 is started, and the driving gear 21 drives the inner gear ring to rotate, and then drives the driven gear 19 to rotate through the outer gear ring 20, drives the barrel 8 to rotate through the barrel shaft 27, and then drives the flexible graphite sealing ring 14 in the supported state to rotate, completing the inspection process of the entire ring surface on both sides. At the same time, the outer visual inspection camera 12 completes the inspection process of the circumferential outer wall. Since the side visual inspection camera 9 and the outer visual inspection camera 12 take multiple photos of the surface of the flexible graphite sealing ring 14, each photo corresponds to a part of the flexible graphite sealing ring 14, compared with the overall shooting inspection, the image analysis burden is reduced and the inspection accuracy is improved.

[0042] After the flexible graphite sealing ring 14 rotates to the inner surface detection position 4, a pair of clamping cylinders 11 are started, and the flexible graphite sealing ring 14 is clamped after passing through the corresponding detection hole 25. At this time, the first conductive head 22 contacts the arc-shaped conductive rail 23, and a pair of springs 34 are energized through the power connection component 26. The spring 34 is energized and contracts to retract the arc-shaped support plate 13, releasing the supporting state, and then the docking cylinder 10 is started to drive the detection cylinder 37 to pass through the docking port, and the docking ring 39 abuts against the docking channel 32. At the same time, the second conductive head 36 contacts the conductive seat 35, and multiple fill lights 29 are powered through the power connection component 26. The light emitted by the fill lights 29 is evenly irradiated to the inner wall of the flexible graphite sealing ring 14. The inner visual inspection camera can capture the inner wall through the reflector 30, and the rotation of the barrel 8 can complete the entire inner wall inspection process.

[0043] After detection, the clamping assembly releases the flexible graphite sealing ring 14, continues to rotate to the unloading position 5, starts the unloading cylinder 17, and passes through the unloading port 24 to push out the tested flexible graphite sealing ring 14 for automatic unloading.
