Description

Technical Field

[0001] This utility model belongs to the field of visual material picking technology and relates to a magnetic vibration material picking disc. Background Technology

[0002] For small components, such as the raster disc in a DVD drive, a vision-based robotic arm is often used to grasp the component facing upwards. A vibrating disc then rotates the component within the disc, causing components facing the opposite direction to flip and be grasped (vision determines orientation, grasping the correctly oriented component; vibration flips the incorrectly oriented component). Current flipping methods are quite violent, primarily involving the entire vibrating disc shaking. This method not only easily causes violent collisions between components but also makes it easy for components to be thrown out of the vibrating disc. Utility Model Content

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by providing a magnetic vibration sorting disc. The technical problem this invention aims to solve is how to generate small-amplitude, uniform vibrations to turn the material.

[0004] The objective of this utility model can be achieved through the following technical solution: A magnetic vibration sorting disc, characterized in that it includes a drum, a material tray, an elastic drum skin located below the material tray, and a magnetic control structure located below the elastic drum skin. The magnetic control structure includes a limiting disc fixed on the drum and located below the elastic drum skin. The limiting disc has a plurality of guide holes arranged longitudinally. A slider is slidably connected longitudinally below the limiting disc. A permanent magnet column corresponding to each guide hole is fixedly arranged on the slider. A lifting component capable of driving the slider to reciprocate longitudinally is arranged between the slider and the drum. A plurality of iron balls are arranged between the elastic drum skin and the material tray.

[0005] Furthermore, the lifting component is an electromagnetic structure or a cylinder.

[0006] In this design, when the permanent magnet moves upwards and approaches the elastic drumhead, the magnetic force attracts the iron balls. Subsequently, as the permanent magnet moves downwards, the iron balls continue to move slightly downwards under the magnetic force, causing localized elastic deformation of the drumhead. This continues until the elastic restoring force exceeds the attraction force of the permanent magnet on the iron balls. At this point, the iron balls lose their attraction and are rebounded by the restoring force of the drumhead. The rebounding iron balls strike the material tray, causing the small workpieces on the tray to vibrate, which in turn probabilistically causes the workpieces above the tray to flip. This method results in a wide and uniform vibration range for the material tray. Attached Figure Description

[0007] Figure 1 This is a schematic diagram of the structure of the vibrating sorting disc.

[0008] Figure 2This is a cross-sectional view of the vibrating sorting disc.

[0009] In the diagram, 1 is the drum; 2 is the feed tray; 3 is the limiting plate; 4 is the guide hole; 5 is the slider; 6 is the permanent magnet column; 7 is the lifting component; 8 is the iron ball bearing; and 9 is the elastic drum skin. Detailed Implementation

[0010] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0011] like Figure 1 and Figure 2 As shown, the device includes a drum 1, a feed tray 2, an elastic drum skin 9 located below the feed tray 2, and a magnetic control structure located below the elastic drum skin 9. The magnetic control structure includes a limiting plate 3 fixed on the drum 1 and located below the elastic drum skin 9. The limiting plate 3 has several guide holes 4 arranged longitudinally. A slider 5 is longitudinally slidably connected below the limiting plate 3. A permanent magnet column 6 corresponding to each guide hole 4 is fixedly arranged on the slider 5. A lifting component 7 that can drive the slider 5 to reciprocate longitudinally is arranged between the slider 5 and the drum 1. Several iron balls 8 are arranged between the elastic drum skin 9 and the feed tray 2. The lifting component 7 is an electromagnetic structure or a cylinder.

[0012] In this design, when the permanent magnet column 6 moves upwards and approaches the elastic drum skin 9, the magnetic force attracts the iron ball 8. Subsequently, as the permanent magnet column 6 moves downwards, the iron ball 8 continues to move slightly downwards under the magnetic force, causing local elastic deformation of the elastic drum skin 9. This continues until the elastic restoring force exceeds the attraction force of the permanent magnet column 6 on the iron ball 8. At this point, the iron ball 8 loses its attraction and is rebounded by the restoring force of the elastic drum skin 9. The rebounded iron ball 8 strikes the material tray 2, causing the small workpieces on the tray 2 to vibrate, which in turn probabilistically causes the workpieces above the tray 2 to flip. In this method, the vibration range of the material tray 2 is wide and the vibration is uniform.

[0013] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
