The invention discloses a UV LED line light source curing machine comprising a shell, a heat dissipating device, a plurality of UV LED light source boards and a plurality of convex lens, wherein the heat dissipating device, the UV LED light source boards and the convex lens are fixedly installed in the shell. The front end of the heat dissipating device forms an inwards recessed face. The UV LED light source boards are fixedly installed on the inwards recessed face of the heat dissipating device side by side, and the light emitting axes of the UV LED light source boards are converged to a convergent point. Each convex lens is correspondingly and fixedly installed at the front end of the corresponding UV LED light source board. The light emitting axis of each UV LED light source board coincides with the main optical axis of the corresponding convex lens, and each UV LED light source board is located at the focus of the corresponding convex lens. The multiple UV LED light source boards and the multiple convex lens are arranged inside the UV LED line light source curing machine, the light emitting axes of the UV LED light source boards and the main optical axes of the convex lens are converged to one point, light sources of the UV light source boards are refracted into parallel light through the convex lens and converged, the illumination intensity at the convergent portion is high, and user demands are met.

Description

technical field [0001] The invention relates to the technical field of ultraviolet curing, in particular to a UV LED line light source curing machine. Background technique [0002] After the UV LED point light source in the IT electronics manufacturing industry, the linear UV LED ultraviolet curing light source has emerged. Unlike the scattered light emitted by the mercury lamp, the ultraviolet light emitted by the UV LED line light source is a narrow linear light that is close to parallel light. It is favored by users for its advantages of energy concentration, high irradiation intensity and high curing efficiency. [0003] However, the current users have higher and higher requirements for the irradiation intensity of the line light source, and hope that the UV LED line light source can provide as high irradiation intensity as possible. At present, some users use the method of increasing the power to enhance the irradiation intensity of UV-LED line light source, but due to...

AI Technical Summary

Problems solved by technology

At present, some users use the method of increasing the power to enhance the irradiation intensity of UV-LED line light source, but due to hardware limitations such as UV LED light source board, it is often not possible to increase its power too much, and the effect of achieving high irradiation intensity is not obvious; In addition, some users increase the arrangement density of UV LEDs in the linear direction to meet the demand for high irradiation intensity. This method improves the irradiation intensity to a certain extent, but the effect is not as good as the user intended.
