[0006] However, even though the cold pressing line and assembly line have been divided and cooperated according to the designer's instructions, due to the fine division of labor in the actual mass production, a little carelessness may cause a large amount of scrapping at the rear end due to the negligence of the front end work point

Embodiment Construction
[0065] The present invention is further illustrated below by means of examples, but the present invention is not limited to the scope of the examples.
[0066] In view of the fact that the size of the light guide plate tends to become thinner gradually, it will be unfavorable for injection mold release during fabrication. However, the thinner light guide plate facilitates extrusion and cutting of cold material. However, it is considered that when extruding and cutting, the knife die will squeeze the edge of the die-cut object, thereby causing extrusion with an uneven surface. Therefore, the manufacturing method of the present invention integrates the light guide plate, the location of the light source, the light guide pattern, and the cutting mold to facilitate the communication between the work stations.
[0067] Based on many years of practical experience and long-term efforts, the inventor analyzed the processing details of each work station in the production process of th...

Abstract
The invention discloses a method for manufacturing a lateral entrance light guide plate with a light incidence structure. The method comprises the following steps: at the light guide pattern design stage, providing a light guide plate layout, wherein the light guide plate layout comprises the external dimension data and the light guide patterns of the light guide plate, wherein when a defined light source is assembled to the side surface of the light guide plate, the light source is close to the front side or rear surface of the light guide plate; at the cutting die manufacturing stage, defining a cutting die layout according to the external dimension data and materials, and manufacturing a cutting die plate; at the light guide pattern processing stage, manufacturing a pattern die according to the light guide patterns, and transferring multiple copies of the light guide patterns onto the material by virtue of the pattern die; and at the cutting die cutting stage, connecting the materials with the light guide patterns by virtue of the cutting die plate, and cutting to form the light guide plate. According to the method for manufacturing the light guide plate disclosed by the invention, the manufacturing mode of each stage of the light guide plate is perfected and integrated, so that communication among various different working sites is promoted, and the yield of terminal products is further wholly improved.
Description
technical field [0001] The invention relates to a method for manufacturing a light guide plate, in particular to a method for manufacturing a side-entry type light guide plate with a light incident structure. Background technique [0002] With the technical development of portable electronic products, the thickness of related products is also moving towards lighter and thinner. The display mode of most electronic products is still through the liquid crystal display screen, wherein the light source of the liquid crystal display screen needs to rely on the backlight module to provide. A common backlight module generally consists of a light guide plate and a light source array. [0003] Such as Figure 1A as shown, Figure 1A It is a processing schematic diagram of the cold material extrusion molding technology of the light guide plate in the prior art. From Figure 1A It can be seen from the figure that in the existing light guide plate cold material extrusion molding techno...
