Abstract

The invention relates to a projection device and an assembly method. The assembly method of the projection device comprises the following steps that: a base and a lens mounting fixture are provided, the base is provided with a part mounting benchmark, the lens mounting fixture is provided with a fixture mounting benchmark, the lens mounting fixture is mounted on the base according to the fixture mounting benchmark; the lens mounting fixture is provided with a lens mounting benchmark, the lens mounting benchmark and the fixture mounting benchmark are coplanar, and a lens is mounted according to the lens mounting benchmark, and the lens is fixed, and the lens mounting fixture is removed; a fluorescence color wheel and a color wheel bracket are provided, the color wheel bracket is provided with a color wheel mounting benchmark, the color wheel is mounted on the color wheel bracket according to the color wheel mounting benchmark; and the color wheel bracket is also provided with a bracket mounting benchmark, the bracket mounting benchmark and the color wheel mounting benchmark are coplanar, and the color wheel bracket is mounted on the base according to the bracket mounting benchmark. With the assembly method of the invention adopted, the lens mounting benchmark and the color wheel mounting benchmark can be located at the same plane, and therefore, tolerance influence can be eliminated, and the quality of the assembled projection device can be ensured.

Description

technical field [0001] The invention relates to a projection device and an assembly method thereof, in particular to a projection device and an assembly method thereof which can make the distance tolerance of two optical elements zero. Background technique [0002] In recent years, large screens have become the most popular keywords in the display field, and the leading product of large screens is projection devices. With the decline in the price of projection devices and the enrichment of functions, the projection device market has gained unprecedented development opportunities , which are widely used in homes, offices, schools and entertainment venues. [0003] When assembling a projection device, when the distance between two optical parts needs to be accurate, but they have to be located on the two components separately, generally the tolerance can only be sacrificed, and the result is that the distance between the two optical parts is not satisfactory for use. need.
