Embodiment Construction

[0021] The present invention will be further described in detail below with reference to specific embodiments, but it is not intended to limit the present invention.

[0022] The following is a specific implementation method of the present invention. In actual production, it is necessary to formulate process parameters and tooling dimensions to achieve process parameters according to the specific requirements of specific finished products.

[0023] (1) Monofilament drawing

[0024] First, select the core material rod and leather glass tube that meet the requirements for careful cleaning and drying. Such as figure 1 As shown, the core material rod 2 is put into the leather material tube 1, and then the rod and tube assembly 3 is clamped on the coarse wire drawing machine to be drawn. The rod and tube assembly is softened in the heating furnace and automatically sags into filaments, and then is drawn by the drawing wheel of the drawing part. The drawn fiber is monofilament 4 with mis...

Abstract

The invention discloses a method for manufacturing a square-filament optical fiber panel. The method comprises the following steps: 1, sleeving a cladding pipe into a core material bar to form a bar and pipe combination, and drawing the bar and pipe combination into monofilaments with unfilled corners; 2, arranging the monofilaments in a primary multi-filament die with a square cross section, aligning the unfilled corners of every four monofilaments together to form a cavity for accommodating light absorbing filaments during arrangement, inserting the light absorbing filaments in the cavity to form a primary multi-filament bar; drawing the primary multi-filament bar to form primary multi-filaments; 3, arranging the primary multi-filaments in a secondary multi-filament die with a square cross section to form a secondary multi-filament bar; drawing the secondary multi-filament bar to form secondary multi-filaments; 4, cutting the secondary multi-filaments short and arranging the short secondary multi-filaments into an optical fiber panel blank; making the optical fiber panel blank into the square-filament optical fiber panel through subsequent processing. The optical fiber panel product is formed through the arrangement of the filaments in square units, the square unit filaments are arranged in the most tightly piled mode, and no clearances exist in the square unit filaments at all. The air tightness can be greatly improved, so that the service life of a low light lever imager is prolonged.

Description

Technical field [0001] The invention relates to the technical field of optical fiber panel production and manufacture, in particular to a method for manufacturing a square-filament optical fiber panel. Background technique [0002] The optical fiber panel is a kind of rigid optical fiber component that is formed by many regular and tightly arranged optical fibers through arranging, fusion pressing, rounding, cutting, finishing and other processes. It has good light collection performance and high resolution. It has the characteristics of zero thickness and can transmit high-definition images without distortion. It is widely used in the input and output screens of various electronic optical devices. [0003] At present, most of the optical fiber panel products are optical fiber panels arranged by circular element filaments, and the circular element filaments are arranged in the most densely packed manner, and there are still gaps. As the input and output screens on the vacuum tube, ...
