Description
Technical Field
The invention relates to a melting and pressing device with sectional heating and a using method thereof in the field of manufacturing of optical fiber panels.
Background
The optical fiber panel, i.e. high-performance optical fiber panel, is an optical fiber element formed by processing thousands of optical fibers which are regularly and closely arranged through the procedures of plate arrangement, hot melt pressing, annealing, rough machining, finish machining and the like, and has the characteristics of high light transmission efficiency, small interstage coupling loss, clear and real image transmission, zero thickness and the like in optics. Fiber optic panels are widely used in various cathode ray tubes, camera tubes, CCD couplings, and other instruments and devices that require the transmission of images. The most typical application is as the optical input and output window of a low-light level image intensifier, which plays an important role in improving the quality of an imaging device.
Currently, fiber optic faceplate blanks are melt-pressed through a forming die. The process can be summarized as follows: 1. drawing and cutting the optical fiber composite wire; 2. orderly arranging the fixed-length optical fiber composite wires into a melt-pressing die; 3. assembling the mold after finishing the arrangement; 4. placing the assembled mould into a melting and pressing furnace, extracting air according to a program, heating, preserving heat and pressurizing; 5. and releasing the pressure, taking the die out of the furnace, cooling and disassembling to obtain the optical fiber panel blank.
In the pressing process, after the end of the optical fiber composite wire is contacted with the surface of the mould, sliding friction is generated between the end of the optical fiber composite wire and the surface of the mould. Since the optical fiber composite filament is in a softened state, the friction force can cause the end of the composite filament to bend. The larger the blank size is, the larger the high-temperature compression amount is, the longer the relative sliding distance between the composite wire end and the surface of the die is, and the more obvious the bending phenomenon is. The problem of bending the end of the optical fiber composite wire is solved, and the utilization rate of effective materials of the blank is limited. The smaller the thickness dimension of the blank (dimension along the light guiding direction of the optical fiber composite filament), the greater the impact of the problem.
At present, in the traditional improvement method, high-temperature lubricant and the like are added between the surface of the die and the end of the optical fiber composite wire to reduce the surface roughness of the die. However, these measures have limitations in view of oxidation of the die surface, extrusion loss of the lubricant, and high temperature contamination of the workpiece.

The traditional melt-extrusion equipment is divided into two types of one-way extrusion and two-way simultaneous extrusion, the optical fiber composite wire 1 ' is heated while being extruded, so that the optical fiber composite wire 1 ' is softened at high temperature to facilitate shaping, and the optical fiber composite wire 1 ' is tightly combined with each other after being cooled to obtain an optical fiber panel blank.
