Abstract

The invention discloses backlight module shading adhesive tape automatic attaching equipment which comprises a rack, a feeding device, a first clamping device, a correcting device, an attaching device, a second clamping device, an edge covering mechanism and a third clamping device. The edge covering mechanism is used for attaching the exposed part of the shading adhesive tape to the lower wall face of the backlight module. In the actual attaching process, three side edges generally need to be wrapped, and the process generally comprises first long edge rubberizing, first long edge wrapping, first short edge rubberizing, first short edge wrapping, second short edge rubberizing and second short edge wrapping. After multi-edge detection of the second detection device, qualified products are screened out, wherein the second detection device can detect whether the covered edges are completely covered or not, whether the shading adhesive tape is wrinkled or not or whether the shading adhesive tape reaches the preset length or not; the wrapping of the side frame is realized, one-time attachment is realized, and the automatic production precision and the production efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display processing equipment, in particular to an automatic attachment equipment for a backlight module light-shielding tape. Background technique [0002] The backlight module is one of the key components of the LCD panel. The function is to supply sufficient brightness and evenly distributed light source so that it can display images normally. The backlight is the light source that provides the LCD panel. It is mainly composed of light source, light guide plate, optical film, plastic frame and so on. The backlight has the characteristics of high brightness, long life and uniform light emission. Light-shielding tape, that is, the tape used to achieve light blocking, is mainly suitable for fixing LCD panels and backlight modules in electronic equipment and various light-shielding applications. Minimize the impact of light in applications that require controlled brightness. [0003] In ...
