Abstract

The invention discloses optical projection equipment. The optical projection equipment comprises an optical machine shell and a cover plate, a containing cavity is formed in the optical machine shell, and the cover plate is used for covering the containing cavity; the lens group comprises a plurality of lenses, and the lenses are positioned in the accommodating cavity; the lens group is provided with a containing cavity, the cover plate covers the containing cavity, the connecting piece is arranged between the lens group and the cover plate, and under the condition that the cover plate covers the containing cavity, the surface, away from the cover plate, of the connecting piece abuts against the upper end face of each lens in the lens group or adheres to the upper end face of each lens in the lens group.

Description

technical field [0001] The present application relates to the technical field of optical devices, and more particularly, to an optical projection device. Background technique [0002] Digital Light Processing (DLP) projector display mode has the characteristics of high brightness, high contrast and high resolution. Combined with LED light source, it can realize miniaturized portable micro-projection, which is welcomed by more and more users. . [0003] In the prior art, glue is dispensed between the lens and the side wall of the optical cabinet, so that the lens is fixed in the optical cabinet. In order to realize the fixation of the lens, at least two dispensing positions are formed between the lens and the side wall of the optical housing, and the dispensing equipment is used to dispense glue at the corresponding dispensing positions one by one. [0004] It can be seen that the current method of dispensing glue between the lens and the side wall of the optical housing wi...
