Description

M261711 4. Creation Instructions (l) —— —__ [Technical Field to which the New Type belongs] This creation is about a clamping mechanism for U, sex substrates in the display of the back projection display display, especially the clamping screen In the case of parts with a middle curtain σ 卩, the holding mechanism of the acrylic plate required by the testing equipment for the testing equipment. It is used in the hall. [Previous technology] The flat-screen TV pontoon 1B ^ ^ rear projection display has the advantages of flat 3, low price, power saving, and large screen. The rear projection shows the optical engine of 般, 隹, and 隹 (^ ^ ^ 2 concentrated in a standard desktop computer in the size of ^ sheep I or light machine), the image signal place ^ * Γ / plus The screen, the power management system, is a △ = k audio system, and then it is assembled in the cabinet, and the rear projection display is neat. Although China ’s technology focus is on the optical machine, the screen (SC Γ een) has about one-tenth of the cost. If the surface of the acrylic part of the screen component has a flaw, such as Scratches or stains will form bright spots or black spots at the corresponding positions in the subsequent display of the display, and may appear as subtle spots in the entire daytime surface, so the acrylic board The quality is not to be overlooked. In the past, the world ’s and Japan ’s printing companies produced acrylic sheets with a key technology. The key technology lies in the chemical treatment of the rear surface of the acrylic sheet. As shown in Figure 1, Figure 1 is the surface pattern of the conventional technology acrylic sheet 2. 4 of the

Page 5 M261711 Fourth, creation instructions (2) Figure. The material for making acrylic plate 2 is made of optical grade Acrylic (acrylic acid) resin. In order to form a screen part, it is necessary to form a black matrix pattern 4 on the surface of acrylic plate 2. The function of the black matrix arrangement pattern 4 is to absorb a part of the ambient light to maintain the high contrast of the picture, and the distribution of the surface pattern 4 on the acrylic plate 2 will also image the quality of the daylight surface. If a rear projection display worth tens of thousands of Taiwan dollars shows slight noise or other visual defects in the daytime surface, it will definitely make consumers hesitate when buying, so the inspection before the acrylic board 2 is shipped In the conventional technology, only a person holds a flexible acrylic plate 2 and visually inspects the distribution of the surface pattern 4 and whether there are other defects under the light. However, in addition to easily contaminating the acrylic plate 2, the inspection environment is extremely unstable. For example, the flexible acrylic plate 2 is dangling, which will affect the quality of the inspection. Therefore, the main purpose of this creation is to provide a clamping mechanism for clamping a flexible substrate to solve the above problems. [New content] The purpose of this creation is to use a clamping mechanism to clamp a flexible substrate such as an acrylic plate to clamp the acrylic plate when detecting the acrylic plate of the screen part in a rear projection display. Acrylic board to stabilize the condition of the acrylic board during inspection.

The middle section of the clamp arm 4804 is connected to the fulcrum 4 8 0 2 differently from the other end of the fixed connection cross bar 46, so that the entire clamp arm 48 04 uses the fulcrum 48 02 to perform lever movement. The end of the clamp arm 48 04 and the surface of the cross bar 46 can be used to clamp the edge of the flexible substrate 34 as a force point for lever movement. The end of the pneumatic rod 48 06 is connected to the other end of the clamping arm 4804 which is different from the end of the flexible substrate 34, and serves as a force application point for the lever movement. !! Further, the aforementioned clamping arms 4 8 0 4 sandwich the ends of the flexible substrate 34 and extend along the edge direction D 2 of the flexible substrate 34 to form a long clamping member 4807 ′ to both sides. The component 4807 can sandwich the flexible substrate 34 more securely. its
