Abstract

The invention discloses a method for attaching a film material of a light guide plate, comprising: placing the light guide plate on a supporting mechanism, moving the film material attaching mechanism to the film material attaching surface corresponding to one side of the light guide plate, and pressing the upper part of the moving member The pressing part and the lower pressing part press the light guide plate in the thickness direction of the light guide plate, the separation member separates the film material on the supply path of the film material from the profile, and the attachment member passes along the path of the light guide plate with a narrow surface or a The film that has been separated from the profile is moved and pressed flat on the film attachment surface of the light guide plate in the way of positive contact of the narrow line, and then the film that has not been separated from the profile is cut by the cutting member And it will not cut off the profile. Adopting the technical scheme of the invention can simplify the inventory management of membrane materials and solve various disadvantages caused by manual pasting.

Description

technical field [0001] The invention relates to the design of a method for attaching a film material, in particular to a method for attaching a film material to a light guide plate. Background technique [0002] In the technical field of backlight modules, the function of the light guide plate is to convert a point light source (light emitting diode LED) or a line light source (cold cathode tube CCFL) into a surface light source for use in a liquid crystal display panel. In the application of the light guide plate in the backlight module, in order to prevent the light from leaking from the side of the light guide plate, usually in the assembly production line, the light guide plate is first placed on the light guide plate holder by manual handling, and then manually. The light-shielding (or light-reflecting) film is attached to two or three sides (sides) of the light guide plate, so as to complete the action of the light guide plate to prevent light leakage. [0003] In the...
