Description

Technical Field

[0001] The present invention belongs to the technical field of optical fiber tapering, and particularly relates to a vertical graphite tapering machine. Background Art

[0002] Currently, all the optical fiber tapering machines used in the core process links of the optical device manufacturing industry adopt a horizontal layout, that is, the tapering parts (optical fibers / optical fiber bundles) are placed horizontally. When the horizontal-layout optical fiber tapering machine is working, the tapering parts move horizontally in the graphite burner head. However, under the high-temperature fire field of the graphite burner head, the horizontal tapering area will be affected by gravity. Especially when drawing a long tapering area, due to gravity, the molten tapering area will sag radially, resulting in a radial offset of the outer periphery of the tapering area, affecting the beam output quality after tapering of the tapering parts. Especially for some laser energy device products with high power (above 2KW) and long tapering area requirements, the existing tapering machines are difficult to meet the quality requirements. Summary of the Invention

[0025] (1) A vertical graphite taper machine of the present invention has a vertical movement layout for tapering. After vertically clamping and fixing the taper part, the tapering process is carried out. During tapering, since the taper part is in a vertical state, the direction of the gravity action is consistent with the axis of the taper area, effectively avoiding the radial offset of the taper area caused by gravity, enabling the core and cladding in the taper area to maintain better concentricity, and thus improving the beam transmission efficiency of the taper part.

Detailed implementation manners

[0042] The following will describe the embodiments of the present invention in detail with reference to the accompanying drawings, so as to more clearly understand the purpose, features and advantages of the present invention. It should be understood that the embodiments shown in the drawings are not a limitation on the scope of the present invention, but only to illustrate the essential spirit of the technical solution of the present invention.

[0043] A vertical graphite taper drawing machine of the present invention includes a taper drawing main machine electronic controller, a taper drawing main machine, and a computer operation terminal. The computer operation terminal is communicatively connected to the taper drawing main machine electronic controller, and the taper drawing main machine electronic controller is electrically connected to the taper drawing main machine. The taper drawing main machine electronic controller is controlled by the computer operation terminal program, and the taper drawing main machine electronic controller executes the program to control the taper drawing main machine to perform actions. The taper drawing main machine electronic controller includes an industrial control computer, a burner controller, and a drive power control box. The industrial control computer controls the taper drawing main machine to execute corresponding action instructions, and at the same time performs data acquisition and image monitoring and processing. The burner controller controls the fire field temperature of the middle section heating and moving component of the taper drawing main machine, and the drive power control box provides power for the entire machine.

[0044] As Figures 1-3 shown. The taper drawing main machine includes an upper clamping and moving component 1, a middle section heating and moving component 2, a lower clamping and moving component 3, an image acquisition component 4, a Z-axis power support component 5, and a main machine base 6. The Z-axis power support component 5 is vertically arranged on the upper surface of the main machine base 6. The upper clamping and moving component 1 is slidably connected to the upper part of the front side surface of the Z-axis power support component 5. The upper clamping and moving component 1 is used to vertically fix the upper end of the taper drawing part and at the same time adjust the position of the upper end of the taper drawing part. The lower clamping and moving component 3 is slidably connected to the lower part of the front side surface of the Z-axis power support component 5. The lower clamping and moving component 3 is used to vertically fix the lower end of the taper drawing part and at the same time adjust the position of the lower end of the taper drawing part. The middle section heating and moving component 2 is slidably connected to the middle part of the front side surface of the Z-axis power support component 5 and is located between the upper clamping and moving component 1 and the lower clamping and moving component 3. The middle section heating and moving component 2 has a graphite burner 25 that can generate a fire field. The fire field is used for the melting and tapering of the taper drawing part. The middle section heating and moving component 2 is also used to adjust the position of the graphite burner 25 so that the center of the fire field and the taper drawing part are coaxial. The image acquisition component 4 is arranged on the main machine base 6 and is spaced opposite to the taper drawing part on the outer peripheral side of the Z-axis power support component 5. The image acquisition component 4 is used to acquire the taper drawing area image of the taper drawing part. During tapering, the Z-axis power support component 5 is used to drive the upper clamping and moving component 1, the middle section heating and moving component 2, and the lower clamping and moving component 3 to move axially respectively, so that the tapering area of the taper drawing part moves vertically up and down at the center in the fire field for tapering.

[0045] Specifically, the Z-axis power support component 5 first drives the middle section heating and moving component 2 to move axially to a suitable position and then fixes it. Then, it simultaneously drives the upper clamping and moving component 1 and the lower clamping and moving component 3 to move axially in the same direction at different speeds so that the tapering area of the taper drawing part is melted and elongated at the center of the fire field. After the elongation is completed, after adjusting the fire field temperature of the graphite burner 25 through the burner controller, the Z-axis power support component 5 drives the middle section heating and moving component 2 to move again so that the graphite burner 25 reciprocates axially along the tapering area for scanning annealing to expand the core diameter of the tapering area.
