Description

Technical Field

[0001] The invention belongs to the technical field of optical fiber jumper polishing, and in particular relates to an automatic polishing wire set for polishing optical fiber MPO jumper. Background Art

[0002] The grinding of optical fiber MPO patch cords is generally divided into the steps of degumming, rough grinding, fine grinding, fiber drawing and polishing. Each step requires the assembly of a grinding fixture and the grinding or polishing on a separate optical fiber grinder. However, since the pigtail cable of the optical fiber MPO patch cord is relatively long, the weight of the entire plate can generally reach 50-100KG. Therefore, when a separate optical fiber grinder is used for grinding or polishing, each grinding step requires the removal of the grinding fixture to clean the end face of the optical fiber MPO patch cord and then assemble it to the grinder of the next step for further grinding. Since the pigtail cable is heavy, the turnover of the optical fiber MPO patch cord is inconvenient during grinding, resulting in low grinding efficiency. Summary of the invention

It should be understood that the embodiments shown in the accompanying drawings are not intended to limit the scope of the present invention, but are only intended to illustrate the essential spirit of the technical solution of the present invention.

[0032] like Figure 1-Figure 8 , Figure 11-Figure 12 The present invention provides an automatic polishing line group for polishing an optical fiber MPO jumper, comprising a plurality of polishing machine groups 1 arranged side by side, a polishing machine 102 for placing a polishing fixture 103 and a cleaning machine 101 for cleaning the polishing fixture 103 are arranged on the table of the polishing machine group 1, a polishing bracket 107 is also arranged on the table of the polishing machine group 1, a linear sliding assembly 105 located above the polishing machine 102 and the cleaning machine 101 is arranged on the polishing bracket 107, a pair of clamp holding assemblies 106 for clamping the polishing fixture 103 are slidably connected to the linear sliding assembly 105, and the linear sliding assembly 105 drives a pair of clamp holding assemblies 106 to synchronously linearly reciprocate to clamp the polishing fixture 103 and move synchronously.

[0033] Specifically, in the present invention, five groups of grinding machine groups 1 are arranged side by side to form an automatic grinding line group, which are degumming grinding, rough grinding, fine grinding, fiber drawing grinding and polishing grinding. Of course, different numbers of grinding machine groups 1 can be arranged to form an automatic grinding line group according to different grinding processes.

[0034] The grinding machine group 1 includes a grinding cabinet 104, and universal wheels 1041 and support seats 1042 are arranged around the bottom of the grinding cabinet 104 for easy movement and support. A grinder 102 and a cleaning machine 101 are arranged horizontally and spaced in the middle of the table top of the grinding cabinet 104. A grinding bracket 107 is arranged at the rear end of the table top of the grinding cabinet 104. The grinding bracket 107 is a door-type bracket, and the two side columns of the door-type bracket are fixed on the table top. The upper end of the grinding bracket 107 extends toward the front side of the grinding cabinet 104, and a linear sliding component 105 is arranged at the end of the extended end. The linear sliding component 105 is located at the upper end of the grinder 102 and the cleaning machine 101.

[0035] The grinder 102 of each grinding machine group 1 is used for grinding the optical fiber MPO jumper connector clamped on the grinding fixture 103, and the cleaning machine 101 is used for cleaning the optical fiber MPO jumper connector on the corresponding grinding fixture 103 after grinding.

[0036] The grinder 101 is preferably an automatic grinder for optical fiber connectors disclosed in publication number CN221583210U, and the cleaning machine 101 is preferably an ultrasonic cleaner.

[0037] When the grinding machine group 1 is working, the linear sliding assembly 105 on each group of grinding machine groups 1 synchronously drives a pair of grinding fixtures 103 connected thereto to move synchronously toward one side of the outer end of the grinder 102 of the grinding machine group 1 to grab the unground grinding fixture 103 on the adjacent side or the grinding fixture 103 that has been ground, and then moves to the other side to place the grabbed grinding fixture 103 on the corresponding cleaning machine 101 or grinding machine 102 for synchronous cleaning or grinding, and then reciprocates in sequence to realize the side-by-side transmission of the grinding fixture 103 on the adjacent grinding machine groups 1 until the cleaning is completed from the last group of grinding machine groups 1 and the entire grinding process is completed.

[0038] A protective cover 4 is provided at the front side of the extended end of the grinding bracket 107 of the grinding machine unit 1 , and the protective cover 4 protects the cleaning machine 101 and the grinding machine 102 on the grinding machine unit 1 to prevent the grinding liquid or the cleaning liquid from splashing when grinding or cleaning the grinding fixture 103 .

[0039] At the same time, a protective door is provided at the rear side of the grinding bracket 107 of each grinding machine group 1, through which the grinding machine 102 or the cleaning machine 101 can be easily installed and debugged.

[0040] Furthermore, a conveyor belt 3 is provided on the table of the grinding unit 1 , and the conveyor belt 3 extends from both ends of the grinding unit 1 .

[0041] Specifically, a conveyor belt 3 is arranged on the front side of the upper end of the table of the grinding cabinet 104, and the conveyor belt 3 is used to transmit the pigtail cable of the optical fiber MPO jumper. When the optical fiber connector on the optical fiber MPO jumper is fixed on the grinding fixture 103 and transported in sequence through the linear sliding assembly 105, the pigtail cable of the optical fiber MPO jumper is placed on the conveyor belt 3 for synchronous transmission.

[0042] Of course, in order to facilitate the transmission of the pigtail cables, a cable box 401 is placed on the transmission belt 3, and the corresponding pigtail cables on each grinding fixture 103 can be placed in the corresponding cable box 401 for synchronous transmission.

[0058] Specifically, one side of the pressurizing cylinder 1091 is fixed to the end of the clamp cylinder 1063 between a pair of clamping plates 1064. When the grinding fixture 103 needs to be pressurized, the pressurizing column on the grinding fixture 103 is first clamped by a pair of clamping plates 1064 on the clamp cylinder 1063 to move the grinding fixture 103 to the grinder 102, and then the pressurizing push rod 1092 is driven downward by the pressurizing cylinder 1091 to pressurize the pressurizing column.
