Description
Technical Field
The present invention relates to the field of laser imaging technologies, and in particular, to a laser imaging power control method, a cascade control system, and related devices.
Background
Laser direct imaging refers to controlling points on a photosensitive coating on an exposure surface to be exposed by laser irradiation, and generating a preset image after development. Compared with the traditional process, the laser direct imaging technology does not need to manufacture a mask, reduces the process complexity, saves the production cost, and can be applied to the fields of screen printing plate making, PCB manufacturing and the like.
The existing laser direct imaging device (for example, application number is 201310084860.3, and the laser direct plate making device for plane screen printing screen) can comprise a laser array composed of a plurality of lasers distributed along a straight line equidistantly, and a plurality of lasers are used for exposing a plurality of rows of pixels on an exposure surface at the same time. In the scanning exposure process, after the type of the photosensitive coating and the thickness of the photosensitive coating are determined, the power for completely exposing the photosensitive coating can be calculated, then the input power of the laser driving circuit is calculated, and finally the input power of a plurality of laser driving circuits is controlled to be a fixed value.
The applicant has noted that during operation of a laser direct imaging device, the power loss of the laser increases with increasing temperature of the laser (so that at the same driving power the output power of the laser decreases), the driving circuit output current of the laser increases with increasing temperature. If the input power of the laser driving circuit is kept unchanged, the output power of the laser driving circuit and the power loss of the laser dynamically change along with the change of the working environment temperature. In view of the above, the output power of a plurality of lasers in the imaging process of the laser direct imaging device is often difficult to be consistent, even the output power of the same laser is unstable, and the consistency of the output power directly influences the consistency of exposure of the laser to the photosensitive coating, so that the consistency of developed images after the photosensitive coating is developed is poor. Therefore, how to ensure the consistency of laser imaging becomes a problem to be solved.
