Description

Technical Field

[0001] This utility model relates to the field of optical cable manufacturing technology, and specifically to an optical cable opening device. Background Technology

[0002] Optical fiber cables are communication cable assemblies that use one or more optical fibers encased in a sheath as the transmission medium and can be used individually or in groups. Before leaving the factory, connectors are usually installed at the ends of the optical fiber cables to enable quick and reliable connections with equipment or other optical fiber cables. During this processing, it is usually required to strip the outer sheath or other outer layers of the optical fiber along the longitudinal direction of the cable end to expose the internal optical fibers, thereby fixing them inside the connector. In existing automated equipment, the openings in the optical fiber cables are prone to leave residues at the ends, resulting in irregular openings. These irregular openings can easily lead to misalignment of the internal fiber cores when connecting to the connector, resulting in insufficient connection reliability. Utility Model Content

[0022] The optical cable opening device of this utility model embodiment is described in detail below with reference to the accompanying drawings.

[0023] Reference Figure 1 As shown, the optical cable 50 opening device provided in this embodiment of the present invention includes: a base 10, a clamping component 20, a slit assembly 30, and a cutting component 40. The clamping component 20 is disposed on one side of the base 10 and is used to clamp and fix the optical cable 50 in the axial direction. The cutting component 40 is disposed on both sides of the optical cable 50 in the radial direction and moves toward the optical cable 50 when driven to cut the optical cable 50 in the circumferential direction. The slit assembly 30 is disposed on the other side of the base 10 and is movable in the axial direction of the optical cable 50 to cut at least two slits 51 opposite each other on both sides of the optical cable 50 in the axial direction and force the outer skin between the at least two slits 51 to be peeled off.

[0024] Reference Figure 2 As shown, the clamping assembly 20 includes: a first pneumatic gripper 21 and two clamping blocks 22. The first pneumatic gripper 21 is fixed on the base 10. The two clamping blocks 22 are respectively disposed on the two gripping fingers of the first pneumatic gripper 21, and move closer or further apart as driven by the first pneumatic gripper 21. Each clamping block 22 has a clamping groove 221, which is located on the side of the clamping blocks 22 that are close to each other. When the optical cable 50 is transported between the clamping grooves 221 of the two clamping blocks 22, the first pneumatic gripper 21 drives the two clamping blocks 22 to move closer to each other, so that the optical cable 50 is clamped and fixed in the initial position by the clamping grooves 221, thereby improving the stability when cutting and stripping the outer sheath of the optical cable 50.

[0025] Reference Figure 4 and Figure 5 As shown, the cutting assembly 40 includes: a third cylinder 41, an insertion block 42, a first stripping blade 44, and a second stripping blade 45. The third cylinder 41 is fixed on the base 10. The insertion block 42 is connected to the third cylinder 41 and is slidably connected to the slide rail on the base 10 via a slider 43. The first stripping blade 44 is located on one side of the insertion block 42 and is inserted between the two cutting seams 51 when driven by the third cylinder 41 to remove the outer sheath between the two cutting seams 51. The second stripping blade 45 is located on the other side of the insertion block 42 and is driven by the third cylinder 41 to remove the outer sheath of the optical cable 50.

[0026] In this embodiment, when the optical cable 50 is opened, the insertion block 42 is driven by the third cylinder 41 to slide towards the optical cable 50, so that the first stripping blade 44 and the second stripping blade 45 enter the insertion port 222 along with the insertion block 42. Since the first stripping blade 44 has a protruding cutting portion 441, the width of the cutting portion 441 is equal to the width between the two cutting blades, and the width of the insertion port 222 is approximately the same as the width of the cutting portion 441, so that the cutting portion 441 can enter the insertion port 222 and be inserted into the sheath of the optical cable 50 in the radial direction, so that the first stripping blade 44 cuts a circumferential strip on the sheath of the optical cable 50. The second stripping blade 45 has a slit in the direction of the optical cable 50, and the slit is spaced at the same distance from at least two cutting slits 51. The second stripping blade 45 may have an arc-shaped blade tip 451, the arc of which is the same as the arc of the optical cable 50. Thus, the arc-shaped blade tip can cut an annular slit at the end of the optical cable 50. Optionally, the clamping block 22 is provided with an insertion slot 224, which is perpendicular to the insertion port 222. The second stripping blade 45 approaches the optical cable 50 through the insertion slot 224, so that the second stripping blade 45 is inserted through the insertion slot 224, thereby cutting an annular slit in the optical cable 50.

[0027] Reference Figure 2 , Figure 3 and Figure 5As shown, the slit cutting assembly 30 includes: a first cylinder 31, a connecting plate 32, a second cylinder 33, a sliding plate 34, a support plate 35, a second pneumatic gripper 36, a connecting block 37, and two slit cutting blades 38. The first cylinder 31 is fixed to the base 10. The connecting plate 32 is connected to the cylinder rod of the first cylinder 31 and extends to the bottom of the base 10, so that the first cylinder 31 can drive the connecting plate 32 to move. By placing the second cylinder 33 at the bottom of the base 10, and placing the sliding plate 34 between the second cylinder 33 and the connecting plate 32 and connecting it to the second cylinder 33, and slidably connecting the connecting plate 32 and the second cylinder 33, the first cylinder 31 can drive the connecting plate 36 to move. 2. During movement, the second cylinder 33 can synchronously drive the sliding plate 34 and the connecting plate 32 to slide in the same direction. One end of the support plate 35 is fixed to the sliding plate 34, so that the support plate 35 can slide with the sliding plate 34. The second pneumatic gripper 36 is fixed to the other end of the support plate 35 and can move with the support plate 35. The connecting block 37 is provided on the gripping fingers of the second pneumatic gripper 36, and both gripping fingers of the second pneumatic gripper 36 are provided with connecting blocks 37, so that the connecting blocks 37 can be driven to move closer or separate by the second pneumatic gripper 36. Two cutting blades 38 are provided on the connecting blocks 37 and are parallel to the axial direction of the optical cable 50 along their own length direction.

[0028] In this embodiment, when slitting the optical cable 50, the second pneumatic gripper 36 drives two slitting blades 38 to cut radially into the sheath of the optical cable 50. Simultaneously driven by the first cylinder 31 and the second cylinder 33, the support plate 35 moves axially along the optical cable 50, causing the slitting blades 38 to cut along the axial direction of the optical cable 50. This results in the slitting blades 38 cutting corresponding slits 51 into the sheath of the optical cable 50. By moving the two slitting blades 38 towards the annular slit, the slitting blades 38 push the outer edge of the annular slit... The outer sheath detaches, and by moving the two slit cutters 38 toward the slit cut by the first stripper 44, the outer sheath between the two slits 51 detaches when the two slit cutters 38 cut to connect with the slit cut by the first stripper 44, thus completing the opening operation of the optical cable 50. It can be understood that each connecting block 37 is provided with two slit cutters 38, and when the two connecting blocks 37 drive their respective two slit cutters 38 to complete the slit operation of the optical cable 50, the outer sheath of the optical cable 50 forms four opposite slits 51, ensuring that the opening of the optical cable 50 is more regular.

[0029] Optionally, the clamping block 22 has an inlet 222 and a clearance opening 223 facing the cutting blade 38. When the cutting blade 38 performs a cutting operation on the optical cable 50, since the inlet 222 connects the cutting assembly 30 and the optical cable 50, the cutting blade 38 can be driven to enter the inlet 222 from the clearance opening 223, so that the two cutting blades 38 can move within the inlet 222 and cut the optical cable 50, ensuring that the movement distance of the cutting blade 38 is limited to the inlet 222, and avoiding the cutting distance of the cutting blade 38 being too long.

[0030] The optical cable 50 opening device provided by this utility model clamps and fixes the optical cable 50 by clamping component 20, and cuts a slit in the optical cable 50 in the circumferential direction by cutting component 40. Then, cutting component 30 cuts at least two cutting slits 51 on both sides of the optical cable 50 in the axial direction and connects them to the above-mentioned slits, so that the outer sheath of the optical cable 50 can be peeled off. This avoids the optical cable 50 end from leaving residue during the opening process, making the opening of the optical cable 50 more regular and ensuring that the internal fiber core is more easily aligned when the optical cable 50 is connected to the connector, thus making the connection more reliable.
