Full-automatic LCD glue dispenser

Abstract

The invention discloses a full-automatic LCD glue dispenser. The full-automatic LCD glue dispenser comprises a feeding and cleaning mechanism, a feeding and carrying arm, a glue dispensing mechanism,a waste material belt, a curing and blanking mechanism and a blanking and carrying arm, wherein the feeding and cleaning mechanism is arranged on a machine table; the glue dispensing mechanism and thecuring and blanking mechanism are respectively arranged behind the feeding and cleaning mechanism at intervals in sequence; the waste material belt is arranged between the glue dispensing mechanism and the curing and blanking mechanism; the feeding and carrying arm is arranged on one side of the glue dispensing mechanism and the curing and blanking mechanism; and the blanking and carrying arm armis arranged above the curing and blanking mechanism in a spanning mode. The full-automatic LCD glue dispenser has the functions of feeding, correcting and cleaning, effectively improves the accuracyof glue dispensing positions and the glue dispensing quality, adopts a multi-station design, can simultaneously complete automatic glue dispensing of a plurality of LCDs, effectively improves the gluedispensing capacity, adopts a material plate with a rectangular path for transferring and blanking, and effectively utilizes the time consumed by transferring and blanking to realize glue layer curing while realizing the centralized high-speed blanking of the LCDs, and the position for blanking can be directly used for subsequent laminating assembly.

Description

technical field [0001] The invention relates to the field of automatic manufacturing, in particular to a fully automatic LCD dispenser. 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, and basically can...

Problems solved by technology

[0003] In the post-assembly process, it is necessary to attach and assemble the OLED panel or LCD and the CG cover. The LCD and the CG cover are rigid structures, so a light-transmitting adhesive needs to be coated between them before the lamination process. Layer, through the adhesive layer to achieve the adhesion of the two; therefore, it is necessary to design an LCD dispenser for coating the adhesive layer on the LCD surface, so that the subsequent cover can be adhered and fixed when the cover is attached; at the LCD point There are the following technical difficulties in the design process of the glue machine: 1. In order to ensure the consistency of the coating position of the glue layer and improve the dispensing quality, it is necessary to correct the position and clean the surface of the LCD before dispensing; 2. The LCD dispensing machine needs to be connected Therefore, the dispensing efficiency and the LCD transportation and cutting after dispensing must meet the high production capacity requirements of the automated line; 3. The glue layer after dispensing on the LCD surface cannot be put into the lower part immediately For assembly in one process, it needs to be placed naturally for 10-20 minutes, and the adhesive layer can be flowed into the next station after the initial curing; therefore, it is necessary to design an LCD flow blanking that not only ensures the production efficiency but also ensures the curing time of the adhesive layer device
