The invention discloses a backlight and LCD automatic assembling machine. The backlight and LCD automatic assembling machine comprises an LCD pre-alignment feeding and transferring mechanism, a rotarytable mechanism, an LCD film tearing mechanism, a backlight feeding mechanism, a backlight alignment and film tearing mechanism, a backlight transferring platform, assembling platforms and duplex carrying arms, and the rotary table mechanism is arranged on a machine table; the LCD pre-alignment feeding and transferring mechanism is arranged on the side portion of a feeding station; the LCD film tearing mechanism is arranged at the side portion of an LCD film tearing station; the backlight feeding mechanism is arranged at the side portion of a laminating and assembling station; the backlight alignment and film tearing mechanism is arranged on the side portion of the backlight feeding mechanism; the assembling platforms are arranged on the side portion of the backlight transferring platformat intervals, and the duplex carrying arms are arranged between the backlight transferring platform and the assembling platforms. According to the invention, LCD automatic feeding and synchronous pre-alignment, LCD film tearing multi-mode integration, roller bonding film tearing rapid detachable installation and fixation, backlight automatic high-precision conveying and transferring, backlight moving automatic alignment and film tearing, film tearing waste automatic blowing-out, and backlight automatic transferring feeding and discharging cooperative linkage are achieved.

Description

technical field [0001] The invention relates to the field of automatic manufacturing, in particular to a backlight and LCD automatic assembly machine. Background technique [0002] The flat panel display device is a human-computer interaction carrier that realizes text and image display. It is mainly composed of a display module, a backlight module and a touch module. The display module is composed of a display panel, a polarizer, a driver chip IC, and a circuit board PCB. And FPC and other components. The production of flat panel display devices is divided into front-end array, box-forming process and back-end module assembly process. The front-end process is used to produce display panels, and the back-end process is used to assemble display panels, polarizers, backlight modules, touch modules and other components into flat panel display devices. The production equipment for the front-end process is currently mainly provided by Japanese, Korean and American companies, an...
