DETAILED DESCRIPTION

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] A welding assembly 3 is provided on the welding area, and the welding assembly 3 includes:

[0046] An optical fiber holder 31, the optical fiber holder 31 is used to place the cut optical fiber;

[0047] Electrode needles 32, a pair of electrode needles 32 are provided for fusing two optical fibers placed on the optical fiber holder 31 together;

[0048] A stripping assembly 4 for removing the outer layer of the optical fiber surface is also fixed on the fusion splicing area. The stripping assembly 4 includes an outer cylinder 41, an outer skin cutter 42 and an inner skin cutter 43. The outer skin cutter 42 is connected to an elastic member 44 and the elastic member 44 is arranged in a groove 6 in the outer cylinder 41. The elastic member 44 moves in the groove 6. The groove 6 is composed of grooves of different depths. The elastic member 44 drives the outer skin cutters 42 on both sides to move toward each other through the deep groove to cut off the outer skin layer of the optical fiber. The elastic member 44 drives the outer skin cutters 42 on both sides to move in the opposite direction through the shallow groove to detach from the optical fiber.

[0049] The endothelial cutter 43 is connected to the second elastic member 45, and the second elastic member 45 is movably connected to the first elastic member 44. The second elastic member 45 and the endothelial cutter 43 are located outside the outer tube 41. The endothelial cutter 43 is separated from the optical fiber, and the second elastic member 45 moves to the inside of the outer tube 41, and the endothelial cutter 43 moves toward each other to cut off the core layer of the optical fiber.

[0050] The optical fiber is inserted into the outer tube 41, and the outer sheath cutter 42 and the inner sheath cutter 43 move in the groove 6 and then move toward each other to cut off the outer sheath layer and the core sheath layer of the optical fiber, and cooperate with the movement of the outer sheath cutter 42 and the inner sheath cutter 43 to peel off the two surface layers of the optical fiber. The stripping component 4 is assembled on the wiring device, and the outer sheath cutter 42 can rotate to completely cut off the harder outer sheath layer of the optical fiber, and cooperate with the inner sheath cutter 43 to remove the core sheath layer of the optical fiber with the peeled outer sheath layer, thereby achieving direct double-layer stripping and simplifying the stripping steps. At the same time, it also avoids the problem that the staff does not bring stripping pliers, resulting in the inability to strip the optical fiber, and the subsequent wiring cannot be carried out.

[0051] A power assembly 5 connected to the peeling assembly 4 is also fixed on the welding area. The power assembly 5 includes a transmission shaft 52, a spiral groove 53 and a return groove 51. The transmission shaft 52 is supported by a bracket on the welding area. A 180° spiral groove 53 is provided on the transmission shaft 52, and both ends of the spiral groove 53 are connected to the return groove 51.

[0052] The transmission shaft 52 is connected to the motor in the fuselage 1 through the intermittent structure 7. The intermittent structure 7 includes an incomplete gear 1 71 and an incomplete gear 2 72. The incomplete gear 1 71 is connected to the transmission shaft 52, and the incomplete gear 2 72 is connected to the shaft of the motor in the fuselage 1. The motor drives the incomplete gear 2 72 to rotate one circle, and the incomplete gear 1 71 rotates 180°.

[0053] The motor in the body 1 is the power. When the motor drives the incomplete gear 2 72 to rotate one circle, the incomplete gear 1 71 rotates 180° only 180°. During the process of the transmission shaft 52 rotating 180°, the spiral groove 53 pushes the transmission rod 54 to move, thereby moving from the groove head to the groove tail of the spiral groove 53.

[0054] The transmission rod 54 sliding in the spiral groove 53 and the return groove 51 penetrates into the strip groove 411 opened on the outer tube 41, and the transmission rod 54 is also connected to the rebound rod 8 between the transmission shaft 52 and the outer tube 41. One end of the rebound rod 8 penetrates into the rebound box 81 on the welding area and connects with the slider 82. The slider 82 is penetrated by the guide rod 83 in the rebound box 81, and one side of the slider 82 is fixed to the inner wall of the rebound box 81 by a damper.

[0055] When the transmission rod 54 moves from the slot head to the slot tail, the slider 82 slides along the guide rod 83, and the spring in the damper is stretched. This process is the driving process.

[0056] When the transmission rod 54 moves to the end of the slot, under the action of the damper spring, the transmission rod 54 will rebound along the return slot 51 to the slot head. This process is a recovery process. At the same time, the action of the damper makes the movement speed of the transmission rod 54 tend to be stable.

[0057] The outer cylinder 41 is also fixed on the fusion area by a bracket. A rotatable drum 9 connected to the transmission rod 54 is arranged inside the outer cylinder 41. A quarter arc groove 91 is provided on the outer wall of the drum 9, wherein one end of the transmission rod 54 is inserted into the arc groove 91. A fiber hole for the optical fiber to pass through is provided inside the drum 9. One end of the drum 9 is connected to the elastic member 44, and the other end of the drum 9 is connected to the optical fiber limiting plate 92. The optical fiber limiting plate 92 is used to limit the stripping length of the optical fiber.

[0058] During the movement, the transmission rod 54 can drive the rotating drum 9 to rotate 90° in the outer drum 41 first, and then rotate along the inner side of the outer drum 41 .

[0059] When the optical fiber is inserted into the drum 9, the end of the optical fiber rests on the optical fiber limiting plate 92, which indicates the required stripping length of the optical fiber, thereby avoiding the existing stripping by feel. If the stripping is too long, it will cause waste, and if the stripping is too short, it will need to be stripped again, resulting in repeated steps.

[0060] The elastic member 44 includes a ring body 441 and an elastic block 442. The ring body 441 is fixed to the port of the drum 9 by bolts. Two symmetrical through holes are opened on the side surface of the ring body 441. The elastic block 442 passes through the through holes. The elastic block 442 is fixed to the partition in the through hole by a spring.

[0061] The outer skin cutter 42 includes a baffle 421, an outer cutter 1 422 and an outer cutter 2 423. The baffle 421 is provided with two pieces, one of which is fixed in the through hole of the ring body 1 441, and the other baffle 421 is connected to the baffle 421 through bolts. The outer cutter 1 422 and the outer cutter 2 423 are arranged between the two baffles 421. The outer cutter 1 422 and the outer cutter 2 423 are respectively connected to the spring block 442 through a rod body passing through the partition. The knife hole formed by the outer cutter 1 422 and the outer cutter 2 423 moving toward each other is used to cut off the outer skin layer of the optical fiber.

[0062] The second elastic member 45 includes a second ring body 451 and an inclined block 452. The second ring body 451 rotates around the first ring body 441. The two through holes on the side surface of the second ring body 451 are used for the inclined block 452 to pass through, and the inclined block 452 is also supported by the spring.

[0063] The inner skin cutting knife 43 has the same structure as the outer skin cutting knife 42 . The knife hole formed by the inner skin cutting knife 43 moving toward each other is smaller than the knife hole of the outer skin cutting knife 42 .

[0064] The outer skin cutter 42 and the inner skin cutter 43 rely on the movement of the spring block 442 and the inclined block 452 to achieve the opposite movement of the cutters to achieve the purpose of cutting the optical fiber skin, and then use the spring to make the cutters move in the opposite direction to detach from the optical fiber.

[0065] The groove 6 includes a front upper arc groove 61, a front lower arc groove 62, a straight groove 1 63, a straight groove 2 64, a rear upper arc groove 65, a rear lower arc groove 66, a limiting groove 67, a straight groove 3 68 and a straight groove 4 69. The front upper arc groove 61 and the front lower arc groove 62 are symmetrically arranged in one end of the rotating drum 9, and the rear upper arc groove 65 and the rear lower arc groove 66 are symmetrically arranged in the other end of the rotating drum 9.

[0066] The two ends of the straight groove 1 63 are respectively connected to one end of the front upper arc groove 61 and the rear upper arc groove 65, and the two ends of the straight groove 3 68 are respectively connected to the other end of the front upper arc groove 61 and the rear upper arc groove 65, and form a groove A;

[0067] The two ends of the straight groove 2 64 are respectively connected to one end of the front lower arc groove 62 and the rear lower arc groove 66, and the two ends of the straight groove 4 69 are respectively connected to the other end of the front lower arc groove 62 and the rear lower arc groove 66, forming a groove B. The two spring blocks 442 slide in the groove A and the groove B respectively.

[0068] There are two limiting grooves 67 symmetrically arranged, and the limiting grooves 67 are used to limit the sliding direction of the inclined block 452.

[0069] The connection between the front upper arc groove 61 and the straight groove 1 63 is flush, the connection between the front lower arc groove 62 and the straight groove 2 64 is flush, the groove depth of the front upper arc groove 61 is greater than the depth of the straight groove 3 68, and the groove depth of the front lower arc groove 62 is greater than the depth of the straight groove 4 69;

[0070] The groove depth of the rear upper arc groove 65 is flush with the connection of the straight groove three 68, and the groove depth of the rear upper arc groove 65 is greater than the depth of the straight groove one 63. The groove depth of the rear lower arc groove 66 is flush with the connection of the straight groove four 69, and the groove depth of the rear lower arc groove 66 is greater than the depth of the straight groove four 69.

[0071] The depths of the front upper arc groove 61 and the front lower arc groove 62 change slowly. The connection between the front upper arc groove 61 and the straight groove three 68 is the deepest, and the connection between the front upper arc groove 61 and the straight groove one 63 is the shallowest. Similarly, the connection between the front lower arc groove 62 and the straight groove four 69 is the deepest, and the connection between the front lower arc groove 62 and the straight groove two 64 is the shallowest.

[0072] The grooves 6 of different depths are used to move the spring block 442 to cut the outer skin layer while the outer skin cutter 42 rotates 90°, and then the outer skin layer is peeled off from the optical fiber as the outer skin cutter 42 moves. As the outer skin cutter 42 moves, the inclined block 452 of the inner skin cutter 43 moves to the limiting groove 67 for moving toward each other to cut the core skin layer of the optical fiber.

[0073] Working principle:

[0074] In the initial state, one end of the transmission rod 54 is located at the groove head of the spiral groove 53, and the other end of the transmission rod 54 is located at the groove head of the arc groove 91. The two spring blocks 442 of the outer skin cutter 42 are located at the deepest part of the front upper arc groove 61 and the front lower arc groove 62. At this time, the cutting distance between the outer skin cutter 42 and the inner skin cutter 43 is the farthest. The optical fiber can pass through the circular hole of the baffle 421, and the optical fiber passes into the rotating drum 9 and connects with the optical fiber limiting plate 92, completing the preparation for optical fiber stripping.

[0075] During peeling, the motor drives the incomplete gear 2 72 to rotate. When the incomplete gear 2 72 rotates to mesh with the incomplete gear 1 71, the incomplete gear 1 71 drives the transmission shaft 52 to rotate 180 degrees. During the rotation of the transmission shaft 52, the spiral groove 53 pushes the transmission rod 54 to slowly move toward the end of the groove. During the movement of the slider, the spring of the damper is slowly stretched. During the movement of the transmission rod 54, since the spring block 442 is at the deepest part of the front upper arc groove 61 and the front lower arc groove 62, the spring block 442 cannot move synchronously with the transmission rod 54 directly. During the movement of the transmission rod 54, the arc groove 91 is pushed to rotate 90 degrees. At this time, the spring block 442 pushes The spring piece 1 44 rotates 90 degrees, so that the outer cutter 1 422 and the outer cutter 2 423 also rotate synchronously, and when the depth of the front upper arc groove 61 and the front lower arc groove 62 gradually becomes shallower, when the spring block 442 slowly moves to the shallow position of the front upper arc groove 61 and the front lower arc groove 62, the spring block 442 drives the outer cutter 1 422 and the outer cutter 2 423 to move toward each other, so as to realize the movement toward each other while rotating, so as to cut the outer skin layer of the optical fiber by rotation. During the rotation of the outer cutter 1 422 and the outer cutter 2 423, since the narrow end of the inclined block 452 is stuck in the limiting groove 67, the inclined block 452 will not rotate with the outer cutter 1 422 and the outer cutter 2 423.

[0076] After the transmission rod 54 drives the arc groove 91 to rotate 90°, the spring blocks 442 on both sides rotate to the straight groove 1 63 and the straight groove 2 64 respectively. At this time, the transmission rod 54 pulls the rotating drum 9 to move synchronously. After the knife holes formed by the outer cutter 1 422 and the outer cutter 2 423 cut the outer skin layer, they follow the synchronous movement of the rotating drum 9 to peel off the cut outer skin layer from the optical fiber. As the rotating drum 9 moves, the wide end of the inclined block 452 moves into the limiting groove 67. At this time, the two inclined blocks 452 will move toward each other, and the inner skin cutter 43 forms a knife hole to cut the core skin layer. The inner skin cutter 43 also peels off the core skin layer during the movement process until the transmission rod 54 moves to the end of the groove and stops;

[0077] The spring block 442 moves to the rear upper arc groove 65 and the rear lower arc groove 66 respectively. Since the grooves of the upper arc groove 65 and the rear lower arc groove 66 are deeper than the straight groove 1 63 and the straight groove 2 64, the spring block 442 will rebound under the push of the spring. At this time, the outer cutter 1 422 and the outer cutter 2 423 move in opposite directions, and the optical fiber can be pulled out from the stripping assembly 4.

[0078] The transmission rod 54 moves toward the groove head along the return groove 51 under the rebound effect of the spring, and due to the depth of the rear upper arc groove 65 and the rear upper arc groove 65, the return movement of the transmission rod 54 drives the rotary drum 9 to rotate in the opposite direction, and the reverse rotation of the rotary drum 9 provides sufficient time for the optical fiber to be extracted;

[0079] When the transmission rod 54 drives the rotating drum 9 to rotate 90° in the opposite direction, the spring block 442 moves to the straight groove three 68 and the straight groove four 69 respectively. As the rotating drum 9 moves, the spring block 442 moves along the straight groove three 68 and the straight groove four 69 back to the front upper arc groove 61 and the front lower arc groove 62. At this time, the knife holes of the outer skin cutter 42 and the inner skin cutter 43 are the largest, which is convenient for inserting the next optical fiber for stripping.

[0080] When the transmission rod 54 moves to the end of the slot, under the action of the damper spring, the transmission rod 54 will rebound along the return slot 51 to the slot head.
