Abstract

The invention discloses a UV-LED curing machine with a light measurement device. The light measurement device comprises a sensor, an irradiatometer and a controller. The sensor is used for sensing ultraviolet light sent by an ultraviolet lamp; the irradiatometer is used for receiving a detection signal of the sensor and calculating the illuminance of ultraviolet rays currently sent out by the ultraviolet lamp and the light accumulation amount increased along with irradiation time and is electrically connected with the sensor; and the controller is used for sending switching control signals of the irradiatometer and the ultraviolet lamp and is electrically connected with the irradiatometer and the ultraviolet lamp. A minimum single chip microcomputer structure is used in the controller, and the irradiatometer which is used for receiving the detection signal of the sensor and calculating the illuminance of the ultraviolet rays currently sent out by the ultraviolet lamp and the light accumulation amount increased along with irradiation time is electrically connected with the sensor through an amplifying circuit; and the inner surface and the outer surface of a shell of a bearing platform are each provided with light absorption paper. According to the curing machine, the control process is more convenient, rapid and precise; the curing quality is ensured; and meanwhile, an operator can be protected against ultraviolet ray radiation, and safety is achieved.

Description

technical field [0001] The invention relates to a light curing device, in particular to a UV-LED curing machine with a light measuring device, belonging to the technical field of curing equipment. Background technique [0002] The working principle of UV curing machine is to irradiate special glue with ultraviolet rays to make the glue polymerize and then cure. But it is especially important to choose a suitable spectrum and curing time. Commonly used UV ultraviolet bands are divided into UVA, UVB, UVC, UVV and other bands, among which the UVA band is more commonly used. Selecting the UV curing machine light source of the corresponding band for the corresponding glue is an important process to improve the curing efficiency. In addition, to improve the curing efficiency, it is necessary to consider factors such as the light source intensity, temperature, power, and irradiation time of the UV UV curing machine. Choosing the right parameters is a prerequisite for curing, whic...
