Abstract

The invention discloses a meniscus gelatinizing device for the single-sided gelatinizing of steel band tapes, which belongs to the field of steel band tape gelatinizing devices for grating ruler manufacturing. The device comprises a driven steel band plate, two steel band plate brackets, a steel band tape horizontal positioning device, a slit plating rod, a glue conveying pipe, a delivery pump, a glue container, a glue solution solidifying device, a driving steel band plate, a vacuumizing system and a driving device, wherein the slit plating rod is located between the driven steel band plate and the driving steel band plate and arranged below the motion plane of a steel band; and the two ends of the delivery pump are connected with the glue conveying pipe, and the glue container is connected with the slit plating rod through the glue conveying pipe and the delivery pump. By using the device disclosed by the invention, a meniscus gelatinizing method can be applied to a one-time gelatinizing process of steel band tapes belonging to a wide and large-surface flexible material, the utilization rate and recovery rate of a glue solution for film coating are both relatively high, and the thickness of a coated film formed by the glue solution can be precisely controlled, and uniform; and in addition, the glue solution for film coating required by the gelatinizing device is easy to prepare, and therefore, the gelatinizing device can well satisfy the gelatinizing requirements of the coated films of the steel band tapes.

Description

technical field [0001] The invention belongs to the field of a steel tape ruler gluing device used for making a grating ruler, and in particular relates to a meniscus gluing device used for gluing one side of a steel tape ruler. Background technique [0002] The grating ruler is a commonly used precision optical detection element. Its manufacturing process is usually based on the steel tape ruler, and a layer of optical glue film is coated on the surface of the steel tape ruler by chemical glue coating method. After the liquid film layer is cured, the photolithography method is used to etch the optical glue film layer to form the photoetching structure required by the grating scale. Therefore, the process of using the chemical glue coating method to coat the steel tape is also called gluing the steel tape. [0003] However, the steel tape ruler is a flexible material, and the existing conventional chemical coating method generally has the disadvantages of low utilization ra...

Problems solved by technology

[0005] In order to solve the deficiencies such as the low utilization rate or recovery rate of the coating glue, the difficulty in controlling the thickness of the glue film, and the poor uniformity of the film thickness, etc. The surface tension, viscosity coefficient, and solvent volatility of the liquid have many requirements, the technical conditions are harsh, and it is difficult to implement, and the existing meniscus coating method can only meet the coating of flexible materials with a relatively narrow width, but cannot meet the requirements of steel tape rulers. The technical problem of the one-time gluing requirement for such a wide width and large surface, the invention provides a meniscus gluing device for one-sided gluing of a steel tape ruler
