Problems solved by technology

In the existing photochemical reaction device, the working power of the light source remains unchanged, and the conveying speed of the conveying equipment is not always in a constant state during the production process. When the conveying speed is slow, the product receives too much radiation, and when the conveying speed is fast, the product Received too little radiation, resulting in increased product defect rates

Abstract

The invention discloses a method and device enabling an object to receive constant irradiation. The device comprises a control unit, a height regulating unit, a light source regulating unit and a detecting unit. The height regulating unit comprises a driving mechanism and a light source frame, wherein the driving mechanism drives the light source frame to move up and down, the driving mechanism is further provided with a position sensor, and the driving mechanism and the position sensor are respectively and electrically connected with the control unit. The light source regulating unit comprises a power supply and a light source which is fixedly arranged on the light source frame, and the control unit, the power supply and the light source are electrically connected in sequence. The detecting unit comprises a velocity sensor and an opto-sensor which are respectively arranged below the light source and are electrically connected with the control unit. By means of the method and device enabling the object to receive the constant irradiation, the irradiation which is received by the object which passes through the position below the light source at any velocity is the same, and the percent of pass of products is improved.

Description

technical field [0001] The present invention relates to equipment for carrying out photochemical reactions, in particular to a method and device for subjecting objects to constant radiation. Background technique [0002] In the photochemical reaction operation, there are certain requirements for the radiation energy of the light source, and according to different photochemical materials and reaction requirements, the light source system is required to provide constant light energy for the photochemical materials. At present, the commonly used light sources are arc discharge lamps and uv-led arrays. The products to be irradiated pass through the "light-receiving surface" under the light source. In order to achieve the expected irradiation effect, the products must receive a certain amount of irradiation. In the existing photochemical reaction device, the working power of the light source remains unchanged, and the conveying speed of the conveying equipment is not always in a ...
