Description

Technical Field

[0001] The invention belongs to the technical field of optical cables, and in particular relates to a device and a method for separating an optical fiber and a sleeve. Background Art

[0002] Optical fiber is the abbreviation of optical fiber, which can be used to transmit signals. Due to its advantages such as high bandwidth, low loss and strong anti-interference ability, optical fiber is widely used in optical fiber image transmission, optical fiber lighting and energy transmission, optical signal control, optical fiber sensing, optical fiber communication, in the fields of mobile, telecommunications, Unicom, radio and television, transportation, etc.

[0033] The present invention is described in detail below so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0034] A brief summary of one or more aspects is given below to provide a basic understanding of these aspects. This summary is not an exhaustive overview of all conceived aspects, and is neither intended to identify the key or critical elements of all aspects nor to define the scope of any or all aspects. Its only purpose is to give some concepts of one or more aspects in a simplified form as a prelude to a more detailed description that will be given later.

[0035] like Figure 1-4 As shown, the present invention discloses a device for separating optical fiber and sleeve, comprising an optical cable pay-off frame 1, an optical cable guide wheel 2, an optical cable 3, an auxiliary traction machine 4, a traction guide wheel 5, a sleeve optical fiber separation mold 6, a waste sleeve take-up frame 7, an optical fiber branching guide wheel I8, an optical fiber scraping sponge 9, an optical fiber degreasing device 10, a collecting bucket 11, a heating device 12, an optical fiber branching guide wheel II 13, an optical fiber take-up frame 14 and a separated optical fiber 15, wherein the optical fiber scraping sponge 9, the optical fiber degreasing device 10, the collecting bucket 11, the heating device 12 The optical fiber post-processing device is constituted, and the optical cable pay-off frame 1 can fix the reel of 800-1200mm specification size to ensure that the optical cable 3 on the reel can be paid out. The optical cable 3 includes a sleeve and a plurality of optical fibers arranged therein. The sleeve and the optical fiber can be separated by the sleeve optical fiber separation mold 6. The waste sleeve cut from the optical fiber is recovered by the waste sleeve take-up frame 7. The separated optical fiber 15 is cleaned by the optical fiber post-processing device and then recovered by the optical fiber take-up frame 14, so as to achieve the purpose of environmental pollution-free and green environmental protection. The present invention can quickly separate the sleeve from the optical fiber with good communication. After the sleeve is stripped, the optical fiber can communicate well and can be connected and tested normally. The stripped optical fiber is collected to prevent excessive attenuation caused by optical fiber winding. The stripped waste sleeve is collected for scrapping, which does not pollute the air and soil, and realizes green environmental protection construction.

[0036] In the present invention, a plurality of cable guide wheels 2 are arranged on the optical cable pay-off frame 1, an auxiliary traction machine 4 is arranged between the optical cable pay-off frame 1 and the downstream sleeve optical fiber separation mold 6, and a plurality of pulling guide wheels 5 are arranged on the auxiliary traction machine 4. The optical cable 3 is pulled onto the sleeve optical fiber separation mold 6 through the optical cable guide wheel 2 and the pulling guide wheel 5. The optical cable 3 is pulled by the auxiliary traction machine 4 to prevent the optical fiber take-up frame 14 and the waste sleeve take-up frame 7 from having too little tension to cut the sleeve.

[0037] The sleeve fiber separation mold 6 is a cylindrical structure with openings at both ends. A center hole 61 is set at the central position inside the sleeve fiber separation mold 6. Several blades 62 are evenly embedded inside the sleeve fiber separation mold 6 and around the center hole 61 for cutting the sleeve from the optical fiber. The separated optical fiber 15 passes through the center hole 61 to ensure that the waste sleeve will not affect the normal communication and use of the optical fiber, thereby playing the role of separating the sleeve and protecting the optical fiber.

[0038] The present invention preferably embeds four blades 62 for dividing the sleeve into four equal parts longitudinally to avoid the friction between the sleeve and the optical fiber causing the optical fiber to break and affect the optical fiber quality. The sleeve cut from the optical fiber is separated from the four sides, and the optical fiber separated from the sleeve passes through the center hole 61, thereby achieving the separation of the sleeve and the optical fiber.

[0039] An optical fiber pay-off rack is arranged upstream of the optical fiber scraping sponge 9, and a plurality of optical fiber branching guide wheels Ⅰ8 are arranged on the optical fiber pay-off rack to separate each optical fiber individually.

[0040] The optical fiber scraping sponge 9 is used to scrape off the oil stains on the surface of the separated optical fiber 15 .

[0041] The optical fiber degreasing device 10 is a cylindrical structure, and is provided with a plurality of through holes 101. A spray column 102 with openings at both ends is longitudinally provided on the optical fiber degreasing device 10, and the through hole 101 runs through the spray column 102. The optical fiber degreasing device 10 is externally connected to an alcohol sprayer, and the low-concentration alcohol sprayed by the alcohol sprayer is sprayed into the spray column 102 through the opening above the spray column 102, and is sprayed onto the surface of the separated optical fiber 15, so as to remove the fiber paste on the surface of the optical fiber, thereby avoiding the contamination of the optical fiber and causing the failure of normal laying out.

[0042] A collecting bucket 11 is provided below the optical fiber degreasing device 10 for collecting the alcohol used to clean the optical fiber to prevent contamination of the ground.

[0043] The heating device 12 is preferably a heating hair dryer, which is used to dry and heat the cleaned optical fiber to facilitate later detection or welding of the optical fiber.

[0044] A plurality of optical fiber distribution guide wheels II 13 are arranged between the heating device 12 and the optical fiber take-up frame 14 to separate each optical fiber individually, thereby preventing the optical fibers from being entangled with each other and affecting the optical fiber take-up.

[0045] The optical fiber take-up frame 14 should be able to take up at least 12 colors of optical fibers or 12 types of optical fiber ribbons to avoid the inability to take up all optical fibers / optical fiber ribbons due to too many cores in the casing.

[0046] The speed and take-up tension of the waste sleeve take-up frame 7 should be consistent with those of the optical fiber take-up frame 14, otherwise the optical fiber and the sleeve will be blocked and the recovered sleeve waste will be scrapped.

[0047] The present invention also discloses a method for separating an optical fiber from a sleeve, wherein the method uses the above-mentioned device for separating an optical fiber from a sleeve to separate the optical fiber from the sleeve, and comprises the following steps:

[0048] The reel with the wound optical cable 3 is fixed on the optical cable pay-off frame 1, the optical cable 3 is paid out, and the optical cable 3 is pulled to the sleeve optical fiber separation mold 6 by the optical cable guide wheel 2 and the pulling guide wheel 5. When the optical cable 3 passes through the sleeve optical fiber separation mold 6, the sleeve is cut off from the optical fiber by the blade 62 on the sleeve optical fiber separation mold 6, and the cut waste sleeve passes through the inside of the sleeve optical fiber separation mold 6 and is taken up on the reel of the waste sleeve take-up frame 7, and the separated optical fiber 15 passes through the central hole 61 on the sleeve optical fiber separation mold 6 and is taken up on the optical fiber reel;

[0049] The optical fiber reel is fixed on the optical fiber pay-off frame, and the optical fiber is split through the optical fiber splitting guide wheel Ⅰ8 and pulled to the optical fiber post-processing device. Each optical fiber passes through the optical fiber oil scraping sponge 9 to scrape the oil on the surface of the optical fiber, and then passes through the optical fiber degreasing device 10. Each optical fiber passes through the through hole 101 on the optical fiber degreasing device 10. The low-concentration alcohol sprayed by the alcohol sprayer is sprayed into the spray column 102 through the opening above the spray column 102, and sprayed onto the surface of the separated optical fiber 15, which plays a role in removing the fiber paste on the surface of the optical fiber to avoid the optical fiber contamination causing the failure of normal pay-off. The alcohol that has been cleaned by the optical fiber is collected by the collecting barrel 11 to prevent contamination of the ground. The optical fiber is dried by the heating device 12, and each optical fiber is separated individually by the optical fiber splitting guide wheel Ⅱ13, and is taken up on the reel of the optical fiber take-up frame 14.
