Abstract

The invention relates to the technical field of spin-coating film preparation, and discloses a spin-coating film preparation device for an optical element by employing a gel method. A first motor is connected with the lower end of a box body in a penetrating manner, and a second motor is connected with the lower end of the box body at the left side of the first motor in a penetrating manner; an output shaft of the second motor extends into the box body and is fixedly connected with a spin-coating table; a feeding hole is formed in each of side walls of the left end and the right end of the boxbody; a first spring is fixedly connected to the outer side of the left side wall of the box body; a limiting block is fixedly connected to the left side of the first spring; and a limiting rod is fixedly connected to the right side of the limiting block. Through cooperative arrangement of motors, a rotating column, sleeves, conducting plates and electromagnets, the effect of keeping constant liquid dropping amount is achieved, and the problem that a large number of spots are generated on the surface of the optical element is solved; and meanwhile, through cooperative arrangement of a threaded rod, a threaded sleeve, the springs and conductive sliding blocks, the problem that a layer of mist film is generated on the surface of the optical element at present is solved.

Description

technical field [0001] The invention relates to the technical field of spin-coating and film-making, in particular to a spin-coating and film-making device for optical elements using a gel method. Background technique [0002] Preparation of thin film by gel spin coating refers to the process of dropping the prepared colloidal solution onto the surface of the optical element, and preparing the corresponding thin film on the surface of the optical element by spin coating. The process flow is: sol configuration, sol aging, heating, Condensation and coating, this preparation process does not require high-cost vacuum equipment, and it is easy to produce uniform films. At present, sol-gel technology has gradually matured, and its application range has continued to expand. It has formed an independent science and technology, which is widely used in polymer chemistry and physics. Chemistry, colloid chemistry and other fields. [0003] The existing device for preparing thin films b...
