Problems solved by technology

If the UV needle tube is exposed to such light for a long time, the UV glue inside will be denatured, resulting in a change in the adhesive strength, which will easily cause OLED (English name is Organic Light Emitting Diode, Chinese name is organic electroluminescent display) Poor packaging
In addition, if the UV needle tube is made of materials such as fully shading metal, it is difficult to visually check the amount of glue in the needle tube
It can be seen that the existing UV needle tube dispensing fixture has certain disadvantages

Abstract

The invention relates to the field of display technology, in particular to a glue dispensing jig. The dispensing fixture includes a fixing device and a needle tube installed on the fixing device, the needle tube is connected with a dispensing needle, and the dispensing tool also includes a shading cover for blocking ultraviolet rays, and the shading cover is located on the needle tube. around, and at least one observation surface for checking the amount of glue in the needle tube is provided on the shading cover. The glue dispensing fixture is used in the UV glue coating process, which can effectively block the ultraviolet light in the white light lamp from directly irradiating the needle tube, thereby avoiding the change of the adhesion strength of the UV glue due to long-term exposure to ultraviolet light. The yield rate of OLED packaging is improved; at the same time, the dispensing fixture can also check the use of the amount of glue in the needle tube at any time, especially the use of the liquid crystal panel to absorb ultraviolet light, so that the dispensing fixture can have a collection barrier The dual functions of external ultraviolet light and intuitive visual inspection of UV glue quantity are integrated.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a glue dispensing jig. Background technique [0002] AMOLED (English name is Active Matrix Organic Light Emitting Diode, Chinese name is Active Matrix Organic Light Emitting Diode) has the characteristics of faster response, higher contrast, wider viewing angle and low temperature resistance. Since 2010, AMOLED panels have been showing steady growth. However, due to the impact of the life of the backlight device, the mass production of AMOLED TV and other large-size products is very slow. Therefore, the backlight packaging technology has become one of the cores of the current research. [0003] At present, the packaging technologies used in large-size AMOLEDs mainly include dam-fill packaging, reverse packaging, and thin-film packaging. Among them, the dam-fill packaging technology belongs to the surface packaging method. Because the underfill glue in this method has high tran...
