During specific work, the cylindrical magnetic rod is randomly placed on the feeding inclined plate 2, the feeding inclined plate 2 is inclined and is designed to automatically feed the rod materials, the vibrator 4 is installed, and the cylindrical magnetic rod is arranged on the inclined surface of the feeding inclined plate 2 and moves towards the push plate mechanism under the action of the vibrator 4. Under the action of the material distributing rod 3, the cylindrical magnetic rods are randomly arranged on the primary movable plate 6 of the push plate mechanism and move upwards along with the primary movable plate. The thicknesses of the primary movable plate 6, the secondary movable plate 7 and the tertiary movable plate 8 are the same and equal to the diameter of the cylindrical bar 32. Similarly, the thicknesses of the first-stage fixed plate 9, the second-stage fixed plate 10 and the third-stage fixed plate 11 are the same and are equal to the diameter of the cylindrical bar 32. Only one bar can be transversely arranged at a certain position on the primary movable plate 6, and the arrangement of the bar on the primary movable plate is determined by the position of the distributing rod.
Because the push plate mechanism is in an inclined arrangement state, in the process of one-time upward movement of the three layers of movable plates, namely the first-stage movable plate 6, the second-stage movable plate 7 and the third-stage movable plate 8 reach the highest point, the cylindrical magnetic rod on the first-stage movable plate 6 can automatically roll to the top surface of the first-stage fixed plate 9 (blocked by the second-stage movable plate 7) under the action of gravity, the cylindrical magnetic rod on the second-stage movable plate 7 can automatically roll to the top surface of the second-stage fixed plate 10 (blocked by the third-stage movable plate 8) under the action of gravity, and the cylindrical magnetic rod on the third-stage movable plate 8 can automatically roll to the inclined surface of the third-stage fixed plate 11 under the action of gravity. By analogy, after each movement of the three layers of movable plates, the rods are increased by one step. Namely, lifting is completed once after three movements, namely, the bar moves from the top surface of the first-stage movable plate to the top surface of the first-stage fixed plate after the first movement, then the bar is continuously lifted by the first-stage movable plate after the first-stage movable plate returns to the original position, and at the moment, the bar positioned on the top surface of the first-stage fixed plate automatically rolls to the second-stage movable plate; after the second movement, the bar positioned on the second-stage movable plate is lifted to the top surface of the second-stage fixed plate, and then the bar positioned on the top surface of the second-stage fixed plate automatically rolls to the third-stage movable plate after the bar is restored to the original position; after the third movement, the bar positioned on the third-stage movable plate is lifted to the top surface of the third-stage fixed plate; so far, the bar is lifted to the highest position by the feeding inclined plate 2 for detection, and the process is circulated, so that the lifting motion is completed.
The magnetic rod rolls on the inclined surface of the third-stage fixed plate 11 and is stopped by the rotating roller 16. The cylindrical magnetic bar is now in the photographing position by means of a CCD camera 29 fixed above. The motor 19 drives the roller 16 to be in a rotating state, the cylindrical magnetic rod rolls between the inclined plane and the roller under the driving of the roller 16, and meanwhile, a CCD camera right above the cylindrical magnetic rod continuously shoots the magnetic column, so that the image acquisition of the whole cylindrical surface is completed, the image is transmitted to a visual detection system, and the defect analysis and judgment are carried out on the picture. After the surface of the cylindrical magnetic rod is detected, the roller moving cylinder moves to drive the moving plate 14 to move backwards along the guide rail 13, and meanwhile, the roller bracket 15 drives the roller 16 to move backwards and separate from the three-stage fixed plate, so that the detected magnetic column is dropped on the qualified product guide plate 21. According to the detection data of the vision system, the material-dividing turning plate cylinder at the corresponding position is controlled to act to control the opening and closing of the material-dividing turning plate, so that unqualified products fall to the unqualified product material guide plate 22 through the corresponding material leakage opening 25, and the classified cylindrical magnetic rods enter the qualified product material box 23 and the unqualified product material box 24 respectively under the action of gravity, thereby completing the classification of the qualified products and the unqualified products. And then, the roller moving cylinder drives the roller to return to the detection position again, and the next detection work cycle is carried out. In specific implementation, the material leakage opening 25 is located below the roller 16 and is as close as possible to the material feeding connection end of the qualified product guide plate 21, so that unqualified products can smoothly pass through the material leakage opening.
Finally, it should be noted that the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, and although the detailed description is made with reference to the embodiments of the present invention, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, which shall be covered by the claims of the present invention.
