Detailed Implementation

[0015] To better understand the improvements made by this utility model compared to the prior art, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0016] like Figure 1As shown, a camshaft visual inspection device mainly consists of a movable support 1, a feeding stepping channel 2, a feeding stepping channel 3, an inspection cylinder group, and a camera group. The inspection cylinder group mainly consists of a rear clamping cylinder 5 and a front clamping cylinder 6. The camera group consists of a rear end face camera 8, a front end face camera 9, and a movable camera 10. The feeding stepping channel 2 and the feeding stepping channel 3 are both equipped with a push cylinder and a lifting cylinder. The lifting cylinder is used to lift the camshaft up and down and, in conjunction with the push cylinder, completes the forward movement of the camshaft.

[0017] The movable support 1 is mounted on the left and right sides of the unloading stepping channel 2 and the loading stepping channel 3. The movable support 1 has X-axis, Y-axis and Z-axis tracks. The main frame of the movable support 1 is the X-axis track, the Z-axis track is movably mounted on the X-axis track, and the Y-axis track is mounted at the bottom of the Z-axis track. The movable camera 10 is set on the end of the Y-axis track and can move arbitrarily in any of the three directions according to the detection requirements. A code reader 4 is provided at the movable camera 10 to read the camshaft serial number.

[0018] The rear end camera 8 and the front end camera 9 are positioned on the left and right sides of the detection point at the junction of the unloading stepping channel 2 and the loading stepping channel 3, corresponding to the two ends of the camshaft. The rear end camera 8, the front end camera 9, and the moving camera 10 are all equipped with light sources for supplementary lighting during shooting. Rear center 12 and front center 13 are correspondingly positioned at the front and rear ends of the camshaft at the detection point, and together with the detection cylinder assembly, the camshaft at the detection point can rotate under the action of the rotary motor 14. The rotary motor 14 is located on the front clamping cylinder 6, and the rear clamping cylinder 5 has a claw-shaped auxiliary cylinder 7 on the side facing the camshaft, used to clamp the camshaft before the rotary motor 14 and the camshaft are positioned. The rotary motor 14 has an elastic pin 11 connected to the camshaft. The elastic pin 11 is mounted on a spring. When a limit connection is made, the camshaft is clamped and fixed by the auxiliary cylinder 7. The rotary motor 14 rotates until the elastic pin 11 is engaged in the pin hole on the camshaft, at which point the auxiliary cylinder 7 is released, and the rotary motor 14 drives the camshaft to rotate.

[0019] The camshaft to be inspected is placed at the feeding stepper channel 3. The lifting cylinder rises, the pushing cylinder advances, the lifting cylinder falls, and the pushing cylinder retracts, thus completing the forward movement of the camshaft. When the camshaft moves to the inspection point, the rear end camera 8 and the front end camera 9 take pictures and record them. When it moves to the position of the moving camera 10, the rear center 12 and the front center 13 advance and press against both ends of the camshaft under the action of the rear clamping cylinder 5 and the front clamping cylinder 6, respectively. The auxiliary cylinder 7 grips the camshaft with its jaws, and the rotary motor 14 rotates to find the pin hole. When the elastic pin 11 is placed at the pin hole, the elastic pin 11 pops out through the spring at its bottom and inserts into the pin hole, completing the connection between the rotary motor 14 and the camshaft. At this time, the auxiliary cylinder 7 is released, and the rotary motor 14 drives the camshaft to rotate. The rotary motor 14 rotates to the scanning angle, and the moving camera 10 moves through the XYZ axes to make the barcode reader 4 scan the QR code for reading and recording. Then, the moving camera 10 is activated to take pictures. Figure 2 As shown, images 1, 3, 5, 7, 9, and 10 are taken in a circular direction. The moving camera 10 is fixed, and the rotary motor 14 rotates more than one revolution to complete the image capture. Images 2, 4, 6, and 8 are taken of the camshaft contour. The moving bracket 1 and the rotary motor 14 work together to complete the image capture. The detection system determines 0K or NG by comprehensively analyzing the front and rear images, the moving camera images, and the QR code.
