5results about How to "Achieve reverse rotation" patented technology

The present invention discloses an optical wrench, comprising a combined optical fiber; a spiral long-period fiber grating, used for mode coupling a resonant wavelength light beam transmitted in the combined optical fiber to form a first vortex light beam; a spiral zone plate, used for topological charge conversion of the first vortex light beam and focusing to form a first focused vortex light beam, and spiral phase modulation of a non-resonant wavelength light beam emitted from the combined optical fiber and focusing to form a second focused vortex light beam. The all-fiber optical wrench can output a first focused vortex light beam and a second focused vortex light beam with opposite topological charges, and then use the first focused vortex light beam and the second focused vortex light beam to drive the particles to achieve forward rotation, reverse rotation and stop rotation. The present invention also provides and a method of using the same, which are applied to the above-mentioned all-fiber optical wrench.

This invention provides a photosensitive adhesive raw material grinding device, including a grinding device body, an inclined guide plate, and a raw material guide plate. The grinding device body has an outward-opening working chamber. The raw material guide plate is fixedly disposed between the two lower walls of the working chamber, guiding the ground photosensitive adhesive raw material for output. Two inclined guide plates are fixedly disposed at the top of the working chamber, with the inclined guide plates on both sides symmetrically positioned. This design uses an infrared temperature monitor to monitor the temperature of the grinding contact point in real time. When the temperature exceeds the limit, it triggers cooling nozzles to spray coolant in a directional manner, preventing the photosensitive adhesive raw material from overheating and denaturing, while also preventing thermal damage to the equipment. The array-style layout of the cooling nozzles ensures uniform cooling, reduces the risk of localized overheating, and extends the service life of the grinding roller.
