The invention relates to a hot air circulation heating device and belongs to the technical field of display panel production. The hot air circulation heating device comprises a heat insulating cover, fans, air heaters and a mixed temperature box, the heat insulating cover is arranged on one side of the mixed temperature box, a heat insulating layer is arranged on the inner wall of the heat insulating cover, a plurality of air heaters and fans are arranged at a position where the mixed temperature box is connected with the heat insulating cover, the fans are positioned at the lower ends of the air heaters, and a positioning jig and an UV lamp are arranged in the mixed temperature box. Heat insulation of the mixed temperature box is realized by simply processing an existing mixed temperature box and heating and circulating air, so that ultraviolet irradiation hardening efficiency can be improved greatly, and ultraviolet irradiation hardening defect rate is reduced.
Description
technical field [0001] The invention relates to a hot air circulation heating device, in particular to a device capable of performing auxiliary heating when ultraviolet rays are irradiated, and belongs to the technical field of display panel production. Background technique [0002] An important direction for the development of displays is the thinning and lightening of the external dimensions. With the emergence of diversified applications, the demand for portability is becoming more and more intense, and the emergence of flat panel display technology has well filled this demand. The development of display devices has gone from CRT to PDP to LCD and OLED. While the display quality can be maintained or even further improved, the size of the display becomes thinner and thinner. The applications on portable devices are becoming more and more abundant, such as mobile phones, notebook computers, tablet computers, e-books and so on. In the process of thinning and lightening, th...
