Description

Light guide plate rubberizing tool Technical Field The utility model belongs to the technical field of manufacturing of liquid crystal display devices, and particularly relates to a light guide plate rubberizing jig. Background The light guide plate is a core optical component in a liquid crystal display device (LCD), and has the main function of converting a line light source or a point light source (such as an LED backlight source) which is shot into a side surface into a uniform surface light source through optical design, so as to provide illumination for a liquid crystal panel, thereby realizing clear and bright picture display, and the light guide plate rubberizing jig is a special tool for assisting in completing the work of rubberizing adhesive tapes or adhesive layers of the light guide plate in the related fields of manufacturing the liquid crystal display device and the like. However, the following problems are found in the implementation related art: the existing light guide plate rubberizing jig is positioned by adopting a simple clamping groove or a fixing support, cannot be accurately matched with light guide plates of different shapes and sizes, is extremely easy to deviate in the rubberizing process, is difficult to ensure the stability of positioning even if a positioning part is arranged due to unreasonable structural design, causes deviation of adhesive tape pasting positions, influences the optical performance and the subsequent display effect of the light guide plate, and is weak in connection between parts because most of the existing rubberizing jigs are not fully considered in the structural design. The connection mode of the positioning column and the jig main body is not stable enough, and is easy to loosen in the repeated use process, so that the positioning is invalid. Disclosure of utility model In order to solve the problems in the background technology, the utility model provides the light guide plate rubberizing jig which has the advantages of accurate positioning, stability, durability, flexibility and universality. The utility model solves the problem of insufficient positioning precision by matching the positioning column with the positioning inserting column, solves the problem of poor structural strength by strengthening connection through the reinforcing block, and solves the problem of poor universality by detachable connection of the plate body. In order to achieve the above purpose, the light guide plate rubberizing jig comprises two plate bodies, wherein the two plate bodies are detachably connected, positioning columns are arranged on the upper surfaces of the two plate bodies, five positioning columns are arranged on one plate body, the five positioning columns are distributed at the same interval, the lower ends of the positioning columns penetrate through the plate body and are provided with mounting blocks, the lower surfaces of the mounting blocks are provided with threaded holes, the lower surfaces of the plate bodies are symmetrically provided with sliding block grooves, one side of one plate body is fixedly provided with a splicing frame, one side of the other plate body is fixedly provided with an inserting plate, and the upper surface of the splicing frame is provided with mounting grooves.
