本發明係關於一種光纖之切斷方法及切斷套組。The invention relates to an optical fiber cutting method and a cutting set.
已知以圓盤狀之切斷刃將複數條光纖依次切斷之方法(例如,參照下述專利文獻1)。於專利文獻1記載之方法中,使切斷刃在左右方向上滑動而逐次一條地切斷在左右方向上排列之複數條光纖。切斷後之光纖之切斷面,與其他光構件光學連接。 [先前技術文獻] [專利文獻] A method of sequentially cutting a plurality of optical fibers with a disc-shaped cutting blade is known (see, for example, Patent Document 1 below). In the method described in Patent Document 1, a plurality of optical fibers arranged in the left-right direction are cut one by one by sliding the cutting blade in the left-right direction.

[發明所欲解決之課題][Problem to be Solved by the Invention]
為了確保光纖之切斷面與其他光構件之光學連接信賴性,而對於光纖之切斷面要求平坦性。然而,於專利文獻1記載之方法中,在快要結束第1條光纖之切斷時,施加於光纖之壓力急劇降低。於是,在刃之移動時易於晃動,因此,於第1條光纖之切斷面形成凹凸。其結果為,有光纖之切斷面之光學連接信賴性低之不良狀況。In order to ensure the reliability of the optical connection between the cut surface of the optical fiber and other optical components, flatness is required for the cut surface of the optical fiber. However, in the method described in Patent Document 1, the pressure applied to the optical fiber drops rapidly when the cutting of the first optical fiber is about to be completed. As a result, it tends to vibrate when the blade moves, and thus irregularities are formed on the cut surface of the first optical fiber. As a result, there is a problem that the reliability of the optical connection at the cut surface of the optical fiber is low.
本發明提供一種可形成平坦之切斷面的光纖之切斷方法及切斷套組。 [解決課題之技術手段] The invention provides an optical fiber cutting method capable of forming a flat cutting surface and a cutting set. [Technical means to solve the problem]
本發明(1)包含光纖之切斷方法,該光纖之切斷方法包含:第1步驟,其準備包含芯及被覆前述芯之包層的光纖即第1線、及與前述第1線平行地排列之第2線;以及第2步驟,其使共通之刃相對於前述第1線與前述第2線相對移動,而切斷前述第1線與前述第2線;且於前述第2步驟中,在前述第1線之切斷結束之前,前述刃切入前述第2線。The present invention (1) includes a method for cutting an optical fiber. The method for cutting an optical fiber includes: a first step of preparing an optical fiber including a core and a cladding covering the core, that is, a first wire; The second line of arrangement; and the second step, which moves the common blade relative to the first line and the second line, and cuts the first line and the second line; and in the second step , before the cutting of the aforementioned first line ends, the aforementioned blade cuts into the aforementioned second line.
根據該方法,於第2步驟中,刃在結束第1線之切斷之前,切入第2線。即,刃在切入第2線後,結束第1線之切斷。因此,抑制在快要結束第1條光纖之切斷時,刃施加於光纖之壓力急劇降低。因此,可抑制刃之晃動。因此,可穩定地切斷第1線。其結果為,可將第1線之切斷面平坦化。因此,該第1線在光學連接信賴性上優異。According to this method, in the second step, the blade cuts into the second line before finishing cutting the first line. That is, after the blade cuts into the second line, it finishes cutting the first line. Therefore, when the cutting of the first optical fiber is about to be completed, the pressure applied to the optical fiber by the blade is suppressed from decreasing rapidly. Therefore, shaking of the blade can be suppressed. Therefore, the first wire can be stably cut. As a result, the cut surface of the first wire can be flattened. Therefore, this first wire is excellent in optical connection reliability.
本發明(2)包含(1)之光纖之切斷方法,其中在前述刃切入前述第1線之重心時、或在此之前,前述刃切入前述第2線。The present invention (2) includes the optical fiber cutting method of (1), wherein the blade cuts into the second wire when the blade cuts into the center of gravity of the first wire or before that.
根據該方法,在刃切入第1線之重心時、或在此之前,刃切入第2線,因此可抑制刃之振動,而可進一步穩定地切斷第1線。According to this method, when the blade cuts into the center of gravity of the first wire or before, the blade cuts into the second wire, so vibration of the blade can be suppressed, and the first wire can be cut more stably.
本發明(3)包含(1)或(2)之光纖之切斷方法,其中在前述刃切入前述第1線之前述芯時、或在此之前,前述刃切入前述第2線。The present invention (3) includes the optical fiber cutting method of (1) or (2), wherein the blade cuts into the second wire when the blade cuts into the core of the first wire or before that.
根據該方法,在刃切入第1線之芯時、或在此之前,刃切入第2線,因此可抑制刃之振動,而可進一步穩定地切斷第1線。According to this method, when the blade cuts into the core of the first wire or before, the blade cuts into the second wire, so vibration of the blade can be suppressed, and the first wire can be cut more stably.
本發明(4)包含(1)至(3)中任一項之光纖之切斷方法,其中前述刃具有直線形狀之刃尖,沿著前述刃尖之方向與前述刃之移動方向為正交。The present invention (4) includes the optical fiber cutting method of any one of (1) to (3), wherein the blade has a straight blade tip, and the direction along the blade tip is perpendicular to the moving direction of the blade. .
根據該方法,因沿著刃尖之方向、與刃之移動方向為正交,故通過光纖斷面的刃之面積變小,而可減少光纖之損傷。According to this method, since the direction along the edge of the blade is perpendicular to the moving direction of the blade, the area of the blade passing through the cross section of the optical fiber becomes smaller, thereby reducing damage to the optical fiber.
本發明(5)包含(1)至(4)中任一項之光纖之切斷方法,其中前述第2線為光纖。The present invention (5) includes the method of cutting an optical fiber according to any one of (1) to (4), wherein the second thread is an optical fiber.
根據該方法,可一次切斷複數條光纖。According to this method, a plurality of optical fibers can be cut at one time.
本發明(6)包含(1)至(4)中任一項之光纖之切斷方法,其中前述第2線為虛設光纖。The present invention (6) includes the cutting method of an optical fiber according to any one of (1) to (4), wherein the second line is a dummy optical fiber.
根據該方法,因第2線為不傳送光信號之虛設光纖,故即便在第2線之切斷面形成凹凸、而非為平坦時,亦可容許該情形。又,藉由將第2線設為虛設光纖而取代光纖,而可提高製造時之光纖之成品率。According to this method, since the second wire is a dummy optical fiber that does not transmit an optical signal, even if the cut surface of the second wire is uneven instead of flat, it can be tolerated. Also, by making the second line a dummy optical fiber instead of an optical fiber, the yield of the optical fiber at the time of manufacture can be improved.
本發明(7)包含一種切斷套組,其係用於實施(1)~(6)中任一項之切斷方法者,且包含:保持構件,其將前述第1線與前述第2線可貫通且可保持;及刃,其具有直線形狀之刃尖,可在向與保持於前述保持構件之前述第1線與前述第2線排列之方向傾斜之方向上移動,且可在與沿著前述刃尖之方向正交之方向上移動。The present invention (7) includes a cutting set, which is used to implement the cutting method of any one of (1) to (6), and includes: a holding member, which connects the aforementioned first wire and the aforementioned second The wire can pass through and can be held; and the blade has a straight edge, which can move in a direction inclined to the direction in which the first wire and the second wire held by the holding member are aligned, and can be aligned with the second wire. Move in the direction perpendicular to the direction of the aforementioned blade tip.
根據該切斷套組,於第2步驟中,刃可在結束第1線之切斷之前,切入第2線。即,刃可在切入第2線後,結束第1線之切斷。因此,可穩定地切斷第1線。可將第1線之切斷面平坦化。其結果為,可以在光學連接信賴性上優異之方式切斷第1線。According to this cutting set, in the second step, the blade can cut into the second thread before ending the cutting of the first thread. That is, the blade can end the cutting of the first line after cutting into the second line. Therefore, the first wire can be stably cut. The cut surface of the first line can be flattened. As a result, the first wire can be cut so as to be excellent in optical connection reliability.
又,根據該切斷套組,因沿著刃尖之方向與刃之移動方向可正交,故通過光纖斷面的刃之面積變小,而可減少光纖之損傷。 [發明之效果] Also, according to the cutting set, since the direction along the edge of the blade can be perpendicular to the moving direction of the blade, the area of the blade passing through the cross section of the optical fiber becomes smaller, thereby reducing damage to the optical fiber. [Effect of Invention]

In addition, the modified example can exhibit the same operation and effect as that of the first embodiment except for the special notes. Furthermore, one embodiment and its modifications can be combined appropriately.
於一實施形態中,使刃4相對於第1光纖線21與第2光纖線22移動。於變化例中,使第1光纖線21與第2光纖線22相對於刃4移動。於變化例中,刃4不可移動,第1光纖線21與第2光纖線22可移動。切斷套組2可與第1光纖線21與第2光纖線22一起移動。In one embodiment, the

刃4之移動方向為上下方向之變化例,相對於刃4之移動方向為左右方向之變化例而言為較佳。其理由在於:通過第1光纖線21與第2光纖線22各者之斷面的刃4之面積變小,而減少第1光纖線21與第2光纖線22之損傷。The moving direction of the
對此,根據一實施形態之方法,如圖1A至圖1C所示般,因沿著刃尖41之方向、與刃4之移動方向為正交,故通過第1光纖線21與第2光纖線22各者之斷面的刃4之面積變小,而可減少1光纖線21與第2光纖線22之損傷。因此,相對於上述之變化例,一實施形態為較佳。In this regard, according to the method of one embodiment, as shown in FIGS. 1A to 1C, because the direction along the
於一實施形態中,作為第2線之一例而舉出第2光纖線22,但第2線亦可為未圖示之虛設光纖。虛設光纖構成為不可進行光學傳送。具體而言,虛設光纖可具有與第1光纖線21相同之第1芯23及第1包層24。虛設光纖之延伸方向之端部被封閉。或者,虛設光纖可不具有第1芯23及第1包層24。因第2線為不傳送光信號之虛設光纖,故即便在虛設光纖之切斷面形成凹凸、而非為平坦時,亦可容許該情形。又,藉由將第2線設為虛設光纖而取代第2光纖線22,而可提高製造時之第1光纖線21之成品率。In one embodiment, the second
如圖5所示般,可利用共通之刃4切斷第1光纖線21與第2光纖線22及虛設光纖27。虛設光纖27配置於第1光纖線21相對於第2光纖線22之相反側。虛設光纖27相對於第2光纖線22之配置,與第2光纖線22相對於第1光纖線21之配置相同。於該變化例中,第2光纖線22為第2線之一例,亦為第1線之一例。於第2步驟中,刃4在結束第2光纖線22之切斷之前,切入虛設光纖27。藉此,除了第1光纖線21外,亦可將第2光纖線22之切斷面平坦化。As shown in FIG. 5 , the
光纖之數目可為3以上之複數。即,相鄰之任意光纖為第1線及第2線。進而,可於複數條光纖之最左側之光纖之左側配置虛設光纖。該情形下,虛設光纖之重心相對於最左側之光纖之重心向下側偏移而配置。The number of optical fibers may be a plural number of 3 or more. That is, adjacent arbitrary optical fibers are the first line and the second line. Furthermore, a dummy optical fiber may be arranged on the left side of the leftmost optical fiber among the plurality of optical fibers. In this case, the center of gravity of the dummy fiber is shifted downward from the center of gravity of the leftmost fiber.
於變化例中,刃為旋轉刃。刃尖具有圓弧形狀。In a variation, the blade is a rotating blade. The blade tip has a circular arc shape.
於變化例中,第1光纖線21及/或第2光纖線22可為剖面矩形形狀。In a variation, the first
