Abstract

The invention discloses an ultraviolet drying machine having a cooling function. The ultraviolet drying machine comprises a stand, wherein a UV curing channel arranged in the stand in the longitudinal direction; multiple UV lamp sets are spaced in the UV curing channel; each UV lamp set comprises a lamp cover fixed on the top wall of the UV curing channel and a UV lamp tube arranged in the lamp cover; fixed frames capable of absorbing infrared rays, curved quartz glass capable of penetrating through the infrared rays and reflecting ultraviolet rays and plane quartz glass capable of penetrating through the ultraviolet rays and reflecting the infrared rays are arranged in the lamp covers; the curved surface quartz glass and the fixed frames are positioned at the upper sides of the UV lamp tubes in sequence; the curved quartz glass is fixed on the fixed frames; and the plane quartz glass is positioned at the lower sides of the UV lamp tubes. The invention further discloses a cooling control method. The ultraviolet drying machine having the cooling function and the cooling control method can effectively reduce the temperature in the glue UV curing process, and guarantee the product quality.

Description

technical field [0001] The present invention relates to an ultraviolet drying machine with cooling function, in particular to an ultraviolet drying machine with cooling function applied in the water glue UV curing process of a touch screen, and also relates to a cooling control method. Background technique [0002] In the manufacturing process of touch screen (ie: touch screen), a key process is the water glue process, that is, using liquid optically transparent glue to bond transparent optical components, and using ultraviolet light with a wavelength of 250-400nm to irradiate the liquid optically transparent The glue is cured, and the capacitive screen is bonded. The core of this process is the curing effect of the liquid optical transparent adhesive by ultraviolet irradiation. The ultraviolet energy and heat generated during the ultraviolet irradiation process are a decisive factor for the curing effect of the water glue. Too low ultraviolet energy will cause the water glu...
