Description

Technical Field

[0001] The utility model belongs to the technical field of optical equipment, and more specifically relates to an optical fiber ribbon cutting knife. Background Art

[0002] In order to facilitate construction and deployment, miniaturization and lightweight of optical cables have become a trend. Optical fiber ribbon cables have many advantages such as high density and small size, and are being used in large quantities. Optical fiber ribbons are thin flat ribbons obtained by curing multiple optical fibers arranged in parallel. Pretreatment may be required before relevant tests or applications. For example, in the sample preparation stage of the optical fiber ribbon geometric dimension test, a cutting knife is required to cut the optical fiber ribbon. However, the existing optical fiber ribbon cutting mainly relies on manual experience, and it is difficult to control the size of the cutting force and maintain the stability of the cutting pressure. During the cutting process, the optical fiber end face is prone to breakage due to uneven force. The poor cutting effect of the optical fiber ribbon will affect the results of subsequent related tests or applications. For example, the poor cutting effect of the optical fiber ribbon will affect the efficiency and accuracy of the optical fiber ribbon geometric dimension test. Utility Model Content

[0020] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0021] Embodiment 1:

[0022] Embodiment 1 provides a fiber ribbon cutting knife, see Figures 1 to 3 , including: a tool holder base 7, a cutting table and a tool holder assembly 6 installed on the tool holder base 7, a force sensor 5 is installed on the working surface of the cutting table and a sample slot 4 is provided, and the sample slot 4 is used to place the optical fiber ribbon; at least one driving assembly is installed on the tool holder assembly 6, and the driving assembly is used to drive the cutting blade 1 connected thereto to move in a direction perpendicular to the working surface of the cutting table, and the force sensor 5 is used to sense and display the pressure value when the cutting blade 1 cuts the optical fiber ribbon.

[0023] The cutting blade 1 includes a blade edge 11 and a support point structure 12, and the blade edge 11 and the support point structure 12 are on the same horizontal line. The driving assembly includes a pressing handle 3 and a telescopic spring 2; one end of the cutting blade 1 is connected to the pressing handle 3, the pressing handle 3 is connected to the telescopic spring 2, and the telescopic spring 2 is connected to the blade holder assembly 6; the pressing handle 3 is used to drive the cutting blade 1 to move to cut the optical fiber ribbon, and the telescopic spring 2 is used to drive the pressing handle 3 back to the initial position when the pressing handle 3 is not pressed (that is, after the pressing handle 3 drives the cutting blade 1 to cut the optical fiber ribbon).

[0024] When fixing the optical fiber ribbon, a corresponding sample clamp can be used. The length of the sample clamp is consistent with the size of the sample slot 4. After fixing, the optical fiber ribbon extending from both ends is flush with the working surface of the cutting table and is located below the cutting blade 1.

[0025] Since the blade 11 and the support point structure 12 are on the same horizontal line, the blade 11 of the cutting blade 1 is in contact with the surface of the optical fiber ribbon while the support point structure 12 of the cutting blade 1 is in contact with the force sensor 5. When the support point structure 12 is in contact with the force sensor 5, the force sensor 5 displays the pressure value when the blade 11 cuts the optical fiber ribbon. In application, after the pressure value displayed by the force sensor 5 reaches the cutting force value (the empirical value for optical fiber ribbons with different core numbers is different and can be obtained in advance as a reference), release the pressing handle 3.

[0026] The tool holder assembly 6 in Example 1 includes a first bracket, which is a T-shaped structure, the lower end of which is fixedly mounted on the tool holder base 7, and the upper end of which is mounted with a driving assembly. A tool groove is mounted on the lateral end of the first bracket, and the cutting blade 1 passes through the tool groove in a direction perpendicular to the working surface of the cutting table, and the tool groove is used to limit or protect the cutting blade 1.

[0027] The working surface of the cutting table is provided with a receiving groove, and the receiving groove is used for installing the force sensor 5, and the receiving groove is also used for providing a moving space for the cutting blade 1 connected to the first bracket.

[0028] The device provided in Example 1 can be used to cut the optical fiber ribbon, and the cutting force can be displayed and observed in real time through the force sensor, which helps to control the size of the cutting force and achieve uniform force on the optical fiber ribbon. It can avoid the breakage of the optical fiber end face due to uneven force, cut a flat optical fiber ribbon end face, and is also conducive to subsequent optical fiber ribbon geometric dimension testing.

[0029] Embodiment 2:

[0030] See also Figures 1 to 3 The difference between Example 2 and Example 1 is that the tool holder assembly in Example 2 further includes a second bracket, which is a T-shaped structure, the lower end of which is slidably mounted on the tool holder base 7, and the upper end of which is mounted with a driving assembly. A tool groove is also mounted on the lateral end of the second bracket, and a cutting blade 1 passes through the tool groove in a direction perpendicular to the working surface of the cutting table, and the tool groove is used to limit or protect the cutting blade 1.

[0031] That is, the tool holder assembly 6 in Example 2 includes a first bracket fixedly mounted on the tool holder base 7 and a second bracket slidably mounted on the tool holder base 7, forming an adjustable tool holder. This adjustable tool holder can adjust the distance within a certain range. The device structure of Example 2 is convenient for efficiently cutting optical fiber ribbons of different lengths as needed.

[0032] Specifically, a slide rail is installed on the tool holder base 7, a slider is installed on the slide rail, and the lower end of the second bracket is connected to the slider. A moving groove is provided on the working surface of the cutting table, and the moving groove is used to install the force sensor 5, and the moving groove is also used to provide a moving space for the cutting blade 1 connected to the second bracket.

[0033] In general, a driving assembly is installed on each of the two brackets in Example 2, and each driving assembly is connected to a cutting blade. The above device structure can be used to cut the two ends of the optical fiber ribbon synchronously or step by step.

[0034] On the basis of the above device structure, by adding a linkage rod to connect the driving components on the two brackets (i.e., the first bracket and the second bracket), the cutting efficiency can be further improved or the cutting operation can be more convenient. That is, a linkage rod is connected between the two driving components respectively installed on the first bracket and the second bracket, and the length of the linkage rod is adjustable. When any of the pressing handles 3 is pressed, the two ends of the optical fiber ribbon can be synchronously cut.

[0035] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to examples, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
