A frame glue coating pre-curing device and method

Abstract

The invention discloses a frame glue coating and procuring device and method. The method comprises the following steps: firstly, providing the frame glue coating and procuring device, which comprises an X-direction ultraviolet source, a Y-direction ultraviolet source, a cylinder, a dispensing valve and a light shield plate, wherein the cylinder can drive the light shield plate to move, and a light hole is formed in the light shield plate; secondly, selecting a proper condensation radius r for an ultraviolet lamp according to the width t of the frame glue coating to ensure that r is more than or equal to t, and setting a related position parameter; finally, setting the relationship between a cylinder stroke s and the related parameter. According to the invention, coating and curing are completed in the same station, so that the working efficiency is improved, and the yield of product is increased. The profile parameter of the light shield plate and the position of the light hole are arranged reasonably, and the cylinder is moved forwards and backwards to control the opening and closing of the shading edges of the light shield plate in X and Y directions so as to control the interlocking of the ultraviolet lamps in the X and Y directions; moreover, the operation is simple and convenient, the cost is reduced greatly and the space is saved.

Description

technical field [0001] The invention belongs to the field of liquid crystal panel lamination production, and particularly relates to a sealant coating pre-curing device and method. Background technique [0002] Liquid crystal display devices have the advantages of being light, thin, short, low power consumption and low heat, which make liquid crystal display devices stand out among different types of display devices and are widely used, such as modern information equipment such as televisions, computers, tablet computers and mobile phones. With the increasing demand for G+G glass (cover plate + functional glass) and TP+Module (touch screen + module) structure in the touch screen industry, and the low bonding efficiency and finished product yield of solid-state optical adhesives, water Glue is bound to become the mainstream trend in the touch screen industry, and the water-adhesive bonding process will be widely used in the back-end bonding of touch screen capacitive screens....

AI Technical Summary

Problems solved by technology

Since the frame glue is coated around, it is necessary to ensure the pre-curing in X and Y directions, but the two UV lamps must be interlocked, because the frame glue cannot be cured repeatedly, and the inner area of ​​​​the functional glass cannot be irradiated to prevent Excessive ultraviolet light decomposes the liquid crystal material in the functional area, increasing the power consumption current of the device
