Abstract

The invention discloses an optical processing turntable, a wavelength conversion module and a projection device. The optical processing turntable comprises a substrate and a driving assembly. The substrate has a holding hole, and a first side and a second side which are opposite to each other. The driving assembly passes through the holding hole and is arranged on the substrate so as to drive the substrate to rotate. The driving assembly is provided with two locking surfaces, wherein the two locking surfaces are respectively positioned on the first side and the second side of the substrate. By adopting the projection device of the optical processing turntable, noise generated by structural vibration can be effectively reduced, and the service life can be prolonged.

Description

technical field [0001] The present invention relates to a turntable, an optical module and a projection device, and in particular to an optical processing turntable, a wavelength conversion module, a projector with the optical processing turntable, and a projector with the wavelength conversion module. Background technique [0002] At present, common wavelength conversion modules, such as fluorescent wheels, are fixed in the optical machine with a locking surface, and the locking surface is located on one side of the stator of the driver. Since the locking surface is not designed at the center of the fluorescent wheel, vibration and noise will be generated due to the unbalanced structure of the fluorescent wheel during operation. Furthermore, the fluorescent layer of the fluorescent wheel is disposed on the other side relative to the locking surface, thus causing the locking surface of the fluorescent wheel to bear a considerable distance of force arm, thereby affecting the ...
