Problems solved by technology

[0005] However, if the dust removal work of the intake fan and the intake duct is performed before assembling the intake fan and the intake duct to the exterior case, even if the dust removal is performed cleanly, after assembling the intake fan and the intake duct to the outside When the shell is attached, dust will also occur and enter, so dust removal is required after assembly
Therefore, there is a disadvantage in that the dust removal work before the assembly of the outer case is meaningless, and the work becomes complicated and the manufacturing time is prolonged.

Embodiment Construction

[0026] Hereinafter, an embodiment of the manufacturing method of the projector of the present invention will be described with reference to the drawings. Moreover, the projector manufactured by this manufacturing method is a device for projecting an image on a screen, and is constructed by assembling a plurality of units and components.

[0027] FIG. 1 is a perspective view of the inside of a projector manufactured by the manufacturing method of the present invention. Furthermore, in order to make it easier to see the units and components assembled inside the projector, this perspective view shows the inside in a state where the control device and the upper casing are removed.

[0028] That is, the projector 1 is configured to roughly have: a lower housing 15 as an external housing; a cooling device 20 mounted on the lower housing 15; a power supply device 40 mounted on the lower housing 15; and a light source that emits light. The device 50; the optical unit 60, which optically p...

Abstract

The invention provides a manufacturing method of a projector. The method can reduce the working procedure quantity of dustproof operation, eliminates the complexity of operation and improves the technical performance. A cooling device forming working procedure is used for assembling a Xiluoke fan (21) and an air inlet side pipeline (30) (an air inlet pipeline (31) and a blast pipeline (35) to form a cooling device (20). A cooling device assembling working procedure is used for assembling the cooling device (20) at a lower casing (15). A power supply device connecting working procedure is used for connecting a power supply device (40) with the Xiluoke fan (21). A dust removing working procedure is used for forcing the Xiluoke fan (21) to rotate and produce attracting wind, which ensures that the sundries of batting, dust etc. inside the air inlet pipeline (31), the Xiluoke fan (21) and the blast pipeline (35) are carried in the attracting wind and are removed to the outside through blowing openings (37 and 39).

Description

Technical field [0001] The invention relates to a manufacturing method of a projector. Background technique [0002] Conventionally, there are known projectors equipped with the following parts: a light source device that emits light; an optical unit that optically processes the light beam emitted from the light source device to form a color image corresponding to the image information; and a projection lens that will come from The image light of the optical unit is projected onto the screen. This projector is constructed by assembling multiple units and multiple components. In addition, the unit is constructed by assembling various components. One of such a plurality of units includes a unit configured by assembling an intake fan and an intake duct to an outer casing (for example, refer to Patent Document 1). In the manufacture of a projector, a process of forming a unit is provided. [0003] On the other hand, in the process of forming a unit, foreign materials such as lint, du...
