Embodiment Construction

[0021] Such as Figure 4 Shown is a best embodiment of the present invention, the flow process of making the aluminum profile surface frame is: first carry out the aluminum profile cross-section design, and then extrude the heated molten aluminum from the die cross-section by extrusion, according to the Cut off the required length, and then process some required holes for locking screws to fix other parts on it, and then process the splicing end faces so that four matching aluminum profiles can form a quadrilateral frame, such as figure 2 , 3 shown. Because it is impossible to directly form columns on aluminum profiles, they can only be installed after processing, or a certain shape of section is designed, and then holes are drilled on the surface specially designed for screw holes. If the cross-sections of two adjacent aluminum profiles are different, the method of processing the splicing end faces is as follows: process the end faces of two adjacent aluminum profiles into...

Abstract

This invention relates to a digital light display back projector and its frame manufactured method including a frame containing four edge frames made of A1 sections in light of the design requirement, each end of the edge frame is processed with a spliced end face matched with the end of an adjacent edge frame connected to form a square frame, some needed holes are processed on the Al sections for locking screws to fix the screen, back cover and other parts on it. When assembling, the screen 2 is placed on frame 1, then screen batten 3 is locked tightly by screws and a sponge strip between 3 and 2, a back cover of the projector is also locked on frame 1 directly.

Description

【Technical field】 [0001] The invention relates to a digital light display rear projection, in particular to a face frame of a digital light display rear projection such as LCD, DLP, LCoS and a manufacturing method thereof. 【Background technique】 [0002] Due to the large size of LCD, DLP, LCoS and other digital light display rear projections, the screen frame is also large. The known rear projection frames are all made of injection molds. Such a large mold costs more than one million yuan to open the mold. Above, the initial investment in product development is too large, but the sales volume of rear projection is small, and the output is also small. This relationship between input and output is extremely unbalanced, which increases the cost of digital light display rear projection and seriously affects the pace of new product development. . 【Content of invention】 [0003] The purpose of the present invention is to solve the high cost problem of the digital light display ...
