Abstract
Description
Technical Field

[0002] Optical fiber consists of a core layer and a cladding layer. The optical fiber whose core layer and cladding are both made of glass materials can be called glass optical fiber. The optical fiber drawn from glass optical fiber for image transmission needs to be split into several short optical fibers during the arrangement process.

The long optical fiber is placed on the workbench, and the cutter cuts the long optical fiber into short optical fibers by longitudinal movement. However, the optical fiber is very brittle. When the sharp cutter contacts the surface of the optical fiber, it is difficult to ensure that the optical fiber only undergoes brittle fracture at the contact position. That is, the location where the brittle fracture occurs may appear near the contact position, resulting in poor length accuracy of the short optical fiber after breaking. Utility Model Content

In the description of the present application, unless otherwise specified, "multiple" means two or more.
[0029] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0030] like Figure 1 As shown, the embodiment of the present application provides an optical fiber breaking mechanism, which includes a cutting assembly 101, a breaking assembly 201 and a conveying structure 301. The conveying structure 301 is used to convey the optical fiber 100 to the cutting assembly 101, and the cutting assembly 101 cuts a cutting mark, i.e., a fracture 105, on the optical fiber 100. It can be understood that the position where the fracture 105 on the optical fiber 100 exists is relatively weak. When a squeezing force is applied to the optical fiber 100, the optical fiber 100 can accurately undergo a brittle fracture at the position of the fracture 105, thereby ensuring the length accuracy of the optical fiber 100 after cutting.
[0031] The conveying structure 301 continues to convey the optical fiber 100 , so that the position of the break 105 of the optical fiber 100 corresponds to the breaking component 201 , and the breaking component 201 applies a squeezing force to the optical fiber 100 , so that the optical fiber 100 is broken at the break 105 .
[0032] like Figure 2 As shown, in some examples, the dicing assembly 101 includes a cutter 102 and an adjustment part, and the cutter 102 is arranged on the adjustment part as a structure for contacting and cutting the optical fiber 100. The cutter 102 adopts a circular blade, and the circular blade is rotatably connected to the adjustment part at the center position. The cutter 102 cuts the optical fiber 100 during the rotation on the adjustment part, thereby forming a fracture 105. The part where the cutter 102 contacts the optical fiber 100 is the position of the minimum thickness of the cutter 102, and the minimum thickness of the cutter 102 is less than 1 mm.
[0033] Furthermore, the adjustment part applies elastic force to the cutter 102, and under the action of the elastic force, the contact area between the cutter 102 and the optical fiber 100 can be controlled. Thus, it is easier to ensure the width and depth of the fracture 105. When the size of the fracture 105 is determined, the shape of the optical fiber 100 after being broken along the fracture 105 is basically determined, and the length accuracy of the optical fiber 100 after cutting can be guaranteed.
[0034] In some examples, the adjustment portion includes a support structure 103 , and when the tool 102 is configured as a circular blade, the center position of the circular blade is rotatably connected to the support structure 103 .
[0035] Furthermore, the elastic force applied by the adjustment part to the tool 102 is realized by the compression spring on the support structure 103, and the tension of the compression spring can be adjusted. By adjusting the tension of the compression spring, the contact area between the tool 102 and the optical fiber 100 can be preliminarily controlled, and it can be preliminarily ensured that the width of the fracture 105 is no more than 50 microns and the depth is no more than 50 microns.
[0036] In some examples, the adjustment part further includes a propulsion structure 104, which is connected to the support structure 103. Driven by the propulsion structure 104, the support structure 103 can approach or move away from the optical fiber 100, so that the cutter 102 on the support structure 103 also approaches or moves away from the optical fiber 100. At the same time, before the cutter 102 cuts the optical fiber 100, the propulsion structure 104 adjusts the initial gap between the cutter 102 and the optical fiber 100 by adjusting the position of the support structure 103.
[0037] Wherein, under the premise of adjusting the tension of the compression spring, the contact area between the cutter 102 and the optical fiber 100 can be further controlled through the pushing action of the pushing structure 104, so as to ensure that the width and depth of the fracture 105 meet the requirements.
[0038] Specifically, when the optical fiber 100 is arranged horizontally, that is, the optical fiber 100 is arranged along the X-axis direction, the propulsion structure 104 can drive the tool 102 to move along the vertical direction, that is, the propulsion structure 104 drives the tool 102 to move along the Z-axis direction.
[0039] In some examples, the dicing assemblies 101 are provided in several groups, specifically, two groups are provided. The two groups of dicing assemblies 101 are respectively located at the top and bottom of the optical fiber 100, and the dicing assemblies 101 can cut the fractures 105 at the top and bottom of the optical fiber 100 respectively.
[0040] Furthermore, the horizontal positions of the two groups of cleaving assemblies 101 are approximately the same, so that the break 105 at the top of the optical fiber 100 corresponds to the break 105 at the bottom of the optical fiber 100. When the optical fiber 100 is broken, the shape of the cross section of the optical fiber 100 is easily controlled.
[0041] The optical fiber cutting mechanism can cut a plurality of optical fibers 100 at the same time, so that the plurality of optical fibers 100 are arranged in parallel, and the optical fibers 100 reach the position of the cutting assembly 101 together.
[0042] Specifically, to ensure that the dicing assembly 101 can cut the fractures 105 on the multiple optical fibers 100 arranged in parallel, the dicing assembly 101 also includes a second power unit, which can drive the cutter 102 to move in the horizontal direction so that the cutter 102 corresponds to different optical fibers 100. It can be understood that, driven by the second power unit, the cutter 102 moves in a direction perpendicular to the extension direction of the optical fiber 100, that is, the second power unit drives the cutter 102 to move along the Y-axis direction.
[0043] like Figure 3 , Figure 4 As shown in the partial enlarged figure 1, the splitting assembly 201 includes a first squeezing part and a second squeezing part, and the first squeezing part and the second squeezing part squeeze or release the optical fiber 100 therebetween in an opening and closing motion, so that the optical fiber 100 is split into short optical fibers of target length. Since a plurality of optical fibers 100 are arranged in parallel, in order to ensure that the first squeezing part and the second squeezing part can squeeze all the optical fibers 100 at the same time, the first squeezing part and the second squeezing part are respectively located at the top and bottom of each optical fiber 100.
[0044] It is understandable that the break 105 already exists at the position where the first extrusion part and the second extrusion part squeeze the optical fiber 100, and the optical fiber 100 will be broken along the break 105, so as to ensure the length accuracy of the short optical fiber.
[0045] Specifically, the breaking assembly 201 further includes a third power unit, which drives the first extrusion part and the second extrusion part to open and close. When the optical fiber 100 is arranged horizontally, the first extrusion part and the second extrusion part move in a vertical direction, that is, the third power unit drives the first extrusion part and the second extrusion part to move along the Z-axis direction.
[0046] In some examples, the first pressing portion includes a first contact structure 202 and the second pressing portion includes a second contact structure 203 . The first contact structure 202 and the second contact structure 203 contact the optical fiber 100 at the top and bottom of the optical fiber 100 , thereby transmitting the pressing force.
[0047] Furthermore, when the squeezing force transmitted to the optical fiber 100 by the first contact portion and the second contact portion is perpendicular to the extension direction of the optical fiber 100, the optical fiber 100 will not have a tendency to brittle fracture. Therefore, the squeezing force transmitted to the optical fiber 100 by the first contact portion and the second contact portion needs to cause the optical fiber 100 to bend to a certain extent, driving the optical fiber 100 to brittle fracture.
[0048] The surfaces of the first contact structure 202 and the second contact structure 203 that contact the optical fiber 100 are working surfaces. When the working surfaces of the first contact structure 202 and the second contact structure 203 are both set as planes, the optical fiber 100 is unlikely to break at the position of the fracture 105 under the extrusion of the two. If the working surfaces of the first contact structure 202 and the second contact structure 203 are both set as non-planar structures, the extrusion of the two provides a bending force in an inclined direction for the optical fiber 100.
[0049] In some examples, the first contact structure 202 is located at the top of the optical fiber 100, and the second contact structure 203 is located at the bottom of the optical fiber 100. Further, the working surface of the first contact structure 202 is concave, and the working surface of the second contact structure 203 is convex, or the working surface of the first contact structure 202 is convex, and the working surface of the second contact structure 203 is concave. It can be understood that the concave structure and the convex structure are interlocked, and under the extrusion of the concave structure and the convex structure, the optical fiber 100 can be broken along the fracture 105 in a bent form.
[0050] In some examples, the first extrusion portion further includes a first base 204, and the second extrusion portion further includes a second base 205. The first contact structure 202 is disposed on the first base 204, and the second contact structure 203 is disposed on the second base 205. The third power unit drives the first base 204 and the second base 205 to perform an opening and closing movement, so that the first contact structure 202 and the second contact structure 203 are moved closer to or farther from each other.
[0051] It is understandable that the first contact structure 202 is disposed on a side of the first base 204 close to the second base 205 , and similarly, the second contact structure 203 is disposed on a side of the second base 205 close to the first base 204 .
[0052] In some examples, the first contact structure 202 and the second contact structure 203 are both made of flexible materials, including but not limited to plastic materials and silicone materials, to prevent the first contact structure 202 and the second contact structure 203 from damaging the optical fiber 100 when contacting the optical fiber 100. The working surfaces of the first contact structure 202 and the second contact structure 203 are set to arc surfaces, inclined surfaces or other non-planar shapes.
[0053] In some examples, the optical fiber 100 breaking mechanism further includes a conveying structure 301, and the conveying structure 301 is located on a side of the cleaving assembly 101 away from the breaking assembly 201, that is, the cleaving assembly 101 is located between the conveying structure 301 and the breaking assembly 201. Then the conveying structure 301 first conveys the optical fiber 100 to the cleaving assembly 101 to cut the fracture 105, and the optical fiber 100 after the fracture 105 is cut is further conveyed by the conveying structure 301 to the breaking assembly 201, so that the optical fiber 100 after the fracture 105 is cut is broken.
[0054] In some examples, a first power unit is disposed on the conveying structure 301 , and the first power unit drives the optical fiber 100 to move in a horizontal direction, thereby pushing the optical fiber 100 to the slicing assembly 101 and the breaking assembly 201 in sequence.
[0055] When a plurality of optical fibers 100 are arranged in parallel, the first power unit drives each optical fiber 100 to move simultaneously. It can be understood that the first power unit drives each optical fiber 100 to move along the X-axis direction.
[0056] In some examples, for a specific image transmission component product, a long optical fiber needs to be split into four short optical fibers, the long optical fiber length is 350 mm, and the target short optical fiber length is 80 mm.
[0057] Step 1: Place 50 long optical fibers in the delivery structure 301 , with the optical fibers 100 arranged in parallel, the head ends aligned, and gaps between adjacent optical fibers 100 .
[0058] Step 2: The conveying structure 301 fixes the head end of the long optical fiber and conveys the long optical fiber. The optical fiber 100 moves along the X-axis so that the first fracture 105 15 mm away from the tail end of the optical fiber 100 is on the plane where the axial center of the tool 102 is located;
[0059] Step 3: Adjust the propulsion structure 104 and the compression spring so that the gap between the cutters 102 is smaller than the thickness of the optical fiber 100, and the cutter 102 moves along the Y axis, i.e., cuts the surface of the optical fiber 100. At this time, the first fracture 105 is formed on the surface of the optical fiber 100, and when the fracture 105 is cut, the cutter 102 is separated from the optical fiber 100;
[0060] Step 4: The conveying structure 301 continues to push the optical fiber 100, so that the break 105 reaches the plane of the breaking component 201 parallel to the X-axis direction, and the moving direction of the optical fiber 100 is perpendicular to the plane. At this time, the breaking component 201 has no contact with the optical fiber 100;
[0061] Step 5: The first base 204 and the second base 205 of the breaking component 201 move toward the direction of the optical fiber 100 at the same time, and finally the first contact structure 202, the second contact structure 203 and the optical fiber 100 contact each other, so that the optical fiber 100 breaks at the position of the first break 105. At this time, the first short optical fiber can be obtained. Since the first short optical fiber is close to 15mm, its length deviation is large due to the length accuracy of the long optical fiber, and it can be used as waste fiber.
[0062] Step 6: Repeat steps 2 to 5, splitting 5 times, and obtain the second to fifth short optical fibers with a length of 80±0.2mm, and a tail of about 15mm. The long optical fiber is evenly split into 4 short optical fibers with a length of 80mm, a total of 200 short optical fiber products, and 2 waste fibers with a length of 15mm.

Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present application.
