Description

Technical Field

[0001] The utility model relates to the technical field of magnetic powder clutch detection devices, in particular to a magnetic powder clutch detection device based on machine vision. Background Art

[0002] Magnetic powder clutch, also known as electromagnetic powder clutch or magnetic powder clutch, is based on the electromagnetic principle and uses magnetic powder to transmit torque. The excitation current and transmission torque are basically in a linear relationship. During the production process of magnetic powder clutch, multiple tests are required to ensure the quality of magnetic powder clutch production.

[0003] For example, the authorization announcement number "CN113607450B" is titled "A Machine Vision-Based Magnetic Powder Clutch Inspection Device." Although it collects information about the magnetic powder clutch through a camera and a distance sensor, and processes the information through a computer, it can detect the size of the magnetic powder clutch. A rotating rod is connected to the magnetic powder clutch, and when the motor is running, it can drive the rotating rod to rotate, which in turn drives the magnetic powder clutch to operate, thereby detecting the life of the magnetic powder clutch. By opening the cylinder, the cylinder drives the detection block to move up and down, allowing the detection block to perform pressure detection on the magnetic powder clutch, thereby enabling the magnetic powder clutch inspection device to perform other tests on the magnetic powder clutch, making it easier for staff to use. However, after the carrier plate carrying the magnetic powder clutch completes a comprehensive inspection, the carrier plate needs to be replaced, which greatly increases the workload and is not conducive to automated production. No sensing device is provided for size detection, life detection, and pressure detection of the magnetic powder clutch, requiring manual observation, which is very inconvenient.

[0020] The drive device includes a motor 12, which is mounted on the upper surface of the center disk 1. The output end of the motor 12 passes through the center disk 1 and is connected to a first connecting rod 13. A second connecting rod 14 is mounted on the upper end of the first connecting rod 13. The upper end of the second connecting rod 14 passes through the working through hole 4 and is connected to the lower surface of the material loading box 11.
