Film-coated precise ink-jet structure

Abstract

The invention discloses a film-coated precise ink-jet structure which comprises a film supply mechanism, a film drawing mechanism, a film stretching mechanism, a film locking mechanism and an ink jet mechanism which are sequentially arranged. The film supply mechanism is used for storing and outputting a coating film. The film drawing mechanism is used for drawing the coating film out of the film supply mechanism to the film stretching mechanism. The film stretching mechanism is used for stretching and straightening the coating film drawn out by the film drawing mechanism. The film locking mechanism is used for pressing the coating film onto a product. The ink jet mechanism is used for spraying ink onto the film-coated product. Through cooperation of the film supply mechanism, the film drawing mechanism and the film stretching mechanism, a lens is covered with the coating film, the center area, namely a non-spraying area, of the lens is blocked, the coating film is reinforced and locked on the lens through the film locking device, and the printing ink is evenly sprayed to the lens through the ink jet device. In the spraying process, the non-spraying area is protected against being covered by the printing ink by the coating film. After spraying is finished, only the coating film needs to be torn, so that the trouble of cleaning the lens is avoided, and the lens production and processing efficiency is improved.

Description

technical field [0001] The invention relates to the field of inkjet devices, and more specifically, to a film-coated precision inkjet structure. Background technique [0002] When producing 3D glass and VR glasses lenses, it is necessary to spray ink around the lens or glass to prevent light leakage and achieve a light-shielding effect. When spraying ink, it is usually sprayed manually, or using equipment for large-scale spraying. However, manual spraying cannot accurately control the spraying position and the amount of spraying, and it is prone to uneven spraying, resulting in uneven thickness, ink shortage and ink overflow. Large-scale inkjet equipment will waste ink and pollute the environment. At the same time, in such a spraying method, the non-spraying area needs to be cleaned and wiped after spraying, which will reduce the efficiency of production and processing. Contents of the invention [0003] In order to overcome the defect that the lens spraying effect in th...
