Embodiment Construction

[0041] In order to make the present invention easier to understand, the present invention will be described in detail below in conjunction with the embodiments and the accompanying drawings, and these embodiments are for illustrative purposes only, and do not limit the scope of application of the present invention.

[0042] As mentioned above, when OLED is packaged, in order to achieve the cumulative light value required for UV glue curing, a long UV irradiation time is required. At this time, the temperature of the glass substrate will also rise significantly, which may affect the OLED organic material. . However, by controlling the UV irradiation time and intermittent irradiation, and then controlling the temperature rise of the glass substrate, the UV light source needs to be switched on and off frequently, which greatly consumes the service life of the light source, and the lighting is staged, and the process takes a long time. The inventors of the present invention found ...

Abstract

The invention relates to a UV glue curing device which comprises a UV light source, a filter, a first substrate, UV glue, a second substrate, a temperature sensor, a UV glue curing machine platform, a temperature control platform and an extract opening, the UV light source, the filter, the first substrate, the UV glue, the second substrate, the temperature sensor, the UV glue curing machine platform and the temperature control platform are arranged in a cavity, and the extract opening is formed in the side wall of the cavity. The invention further provides a UV glue curing method, the method is easy to operate, heat in the cavity can be effectively diffused by the aid of the matched actions of the temperature control platform, the temperature sensor and the extract opening, and the purpose for controlling the surface temperature of the second substrate is realized. The UV glue curing device and curing method are applied to OLED packaging, the problem that the service life of a light source is shortened due to the fact that the power supply is switched on and off frequently can be solved, and the processing time is greatly reduced simultaneously.

Description

technical field [0001] The invention belongs to the technical field of UV glue curing, and in particular relates to a UV glue curing device and a curing method thereof. Background technique [0002] UV glue, also known as shadowless glue, photosensitive glue, and ultraviolet light curing glue, refers to a type of adhesive that must be cured by ultraviolet light and can be used as an adhesive. UV glue has many advantages, such as fast curing at room temperature, energy saving, long service life, high bonding strength, etc., and can be widely used in medical and health, aviation, electronic assembly, printing, optical instruments, packaging, national defense and military industries. [0003] Organic light emitting diode or organic light emitting display (Organic Light Emitting Diode Display, OLED), also known as organic electroluminescent diode, is a new type of display technology developed since the middle of the 20th century. Compared with liquid crystal displays, organic e...
