Description

Technical Field

[0001] The invention relates to the field of optical fiber jumper processing, in particular to an automatic crimping device for optical fiber jumper connectors and a crimping method thereof. Background Art

[0002] Fiber optic patch cables are used to connect devices to fiber optic cabling links. They have a thick protective layer and are generally used to connect optical terminals and terminal boxes. They are used in fiber optic communication systems, fiber optic access networks, fiber optic data transmission, and local area networks. A fiber optic patch cable is a fiber optic cable with connector plugs installed at both ends to achieve active connection of the optical path. The end with a plug is called a pigtail. Fiber optic patch cables are similar to coaxial cables, but without the mesh shield. At the center is a glass core for light propagation. In multimode fiber, the core diameter is 50μm to 65μm, roughly the thickness of a human hair, while the core diameter of single-mode fiber is 8μm to 10μm. The core is surrounded by a glass envelope with a lower refractive index than the core to keep the fiber contained. A thin plastic jacket protects the envelope.

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention. Example 1

[0036] See also Figure 1-5 An automatic crimping device for optical fiber jumper connectors and a crimping method thereof include a connecting frame 1 and a base 4 installed at the lower end of the connecting frame 1. One end of the connecting frame 1 is slidably connected to a squeezing rod 2. The interior of the base 4 is rotatably connected to two ironing devices 5. The ironing devices 5 are used to iron and fuse the optical fiber jumper and the optical fiber connector.

[0037] The ironing device 5 includes a connecting ring 56 rotatably connected to the inside of the extrusion rod 2. One end of the connecting ring 56 is slidably connected to the first fusing block 52. One side of the first fusing block 52 is slidably connected to the second fusing block 59. The first fusing block 52 and the second fusing block 59 are used to fuse the optical fiber jumper and the optical fiber connector.

[0038] The interior of the connecting ring 56 is slidably connected to a connecting sleeve 12, and a plurality of folding plates 13 are provided at both ends of the connecting sleeve 12;

[0039] An inclined surface 57 is provided on one side of the first fusing block 52. The inclined surface 57 is used to spray colloid onto the outer surfaces of the optical fiber jumper and the optical fiber connector.

[0040] according to Figure 1 As shown, the optical fiber jumper 10 and the optical fiber head 11 pass through the two ironing devices 5, so that one end of the optical fiber head 11 is inside the card seat 14. At this time, the connection between the optical fiber jumper 10 and the optical fiber head 11 is located between the two ironing devices 5. Figure 3 As shown, the rack plate 3 is driven downward by the extrusion rod 2 to slide, and the rack plate 3 is engaged with the gear ring 55, so that the gear ring 55 rotates, and the rotating gear ring 55 drives the connecting ring 56 to rotate. When the connecting ring 56 rotates, the connecting ring 56 drives the first melting block 52 to rotate, and the first melting block 52 is electrically heated, so that the first melting block 52 heat-melts the outer surfaces of the optical solder jumper 10 and the optical solder head 11. The outer surfaces of the optical solder jumper 10 and the optical solder head 11 are melted by the first melting block 52, thereby forming an annular groove on the outer surfaces of the optical solder jumper 10 and the optical solder head 11, and then the second melting block 59 is slid inside the first melting block 52, and one side of the annular groove is melted by the second melting block 59, so that the cross section of the annular groove becomes a right angle. The specific hot-melt shape can be referred to. Figure 4 , glue is sprayed toward the connection between the optical fiber jumper 10 and the optical fiber head 11 through the inclined surface 57, and then the connecting sleeve 12 is slid between the optical fiber jumper 10 and the optical fiber head 11, and the gear ring 55 and the first hot melting block 52 are rotated again, and the folding plate 13 is squeezed by the first hot melting block 52, so that the folding plate 13 is inserted into the annular groove, and then the second hot melting block 59 inside the first hot melting block 52 is extended again, and one end of the folding plate 13 is bent by the second hot melting block 59, so that the bent folding plate 13 is inserted into the annular groove, thus completing the fixed crimping between the optical fiber jumper 10 and the optical fiber head 11. After crimping in the above manner, the folding plate 13 will be firmly buckled on the outer surface of the optical fiber jumper 10 and the optical fiber head 11, and further fixed by the glue, so that the optical fiber jumper can be used for a long time without falling off;

[0041] It should be noted that when the first melting block 52 and the second melting block 59 heat-melt the outer surfaces of the optical fiber jumper 10 and the optical fiber head 11, semi-solidified plastic liquid will be generated on the outer surfaces of the optical fiber jumper 10 and the optical fiber head 11. Therefore, when the folding plate 13 is bent and snapped onto the outer surfaces of the optical fiber jumper 10 and the optical fiber head 11, the solidified plastic liquid further adheres to the folding plate 13, thereby enhancing the connection strength. Example 2

[0042] This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-5 A pushing device 6 is also provided inside the extrusion rod 2. The pushing device 6 includes a first piston cylinder 62 installed inside the extrusion rod 2. The first piston cylinder 62 is slidably connected to the inside of the first piston cylinder 61. The first piston rod 61 is used to push the connecting sleeve 12 between the fiber optic jumper and the optical fiber connector. The first piston rod 61 and the first piston cylinder 62 are connected by a second spring 63.

[0043] according to Figure 2As shown, when the connecting ring 56 rotates to drive the first melting block 52 to form an annular pit on the outer surface of the optical fiber jumper 10 and the optical fiber head 11, the first piston rod 61 slides to the right, and the first piston rod 61 pushes the folding plate 13 to slide to the right, so that the folding plate 13 and the connecting sleeve 12 move between the two ironing devices 5;

[0044] An inflatable device 8 is installed inside the extrusion rod 2. The inflatable device 8 includes air bag rings 81 arranged at both ends of the connecting ring 56. The air bag rings 81 are used to clamp the fiber jumper and the optical fiber connector.

[0045] according to Figure 3 As shown, since the inner diameter of the connecting ring 56 is large, the optical fiber jumper 10 and the optical fiber head 11 cannot be located at the axis of the connecting ring 56. Therefore, an air bag ring 81 is installed at one end of the connecting ring 56. When the optical fiber jumper 10 and the optical fiber head 11 are located inside the connecting ring 56, air is transmitted to the air bag ring 81 to expand the air bag ring 81. The expanded air bag ring 81 is used to support the optical fiber jumper 10 and the optical fiber head 11, so that the optical fiber jumper 10 and the optical fiber head 11 are located at the axis of the connecting ring 56, so that the first hot melting block 52 can be evenly hot-melted into the annular groove on the outer surface of the optical fiber jumper 10 and the optical fiber head 11, and the folding plate 13 can also be better snapped into the annular groove. Example 3

[0046] This embodiment is an improvement made on the basis of embodiment 2. For details, please refer to Figure 1-6 The inflation device 8 further includes a second piston cylinder 82 mounted inside the extrusion rod 2. A sealing disk 84 is slidably connected to the interior of the second piston cylinder 82. A sliding rod 83 is mounted on the lower end of the sealing disk 84. The sliding rod 83 is connected to the second piston cylinder 82 via a fourth spring 85. The sliding rod 83 passes through the lower end of the second piston cylinder 82.

[0047] A convex plate 15 is installed at one end of the connecting ring 56, and the convex plate 15 is used to abut against the slide rod 83. A second air pipe 86 is installed on one side of the second piston cylinder 82, and the lower end of the second air pipe 86 is connected to the interior of the airbag ring 81.

[0048] according to Figure 6 As shown, when the ring gear 55 drives the connecting ring 56 to rotate, the connecting ring 56 also drives the cam plate 15 to rotate, and the cam plate 15 is used to squeeze the slide rod 83 inside the second piston cylinder 82 upward, so that the cam plate 15 is used to squeeze the slide rod 83 to slide upward, and the slide rod 83 is used to push the sealing plate 84 upward to slide, and the sealing plate 84 is used to squeeze the air inside the second piston cylinder 82 to the airbag ring 81, so that the airbag ring 81 expands. Example 4

[0049] This embodiment is an improvement made on the basis of embodiment 3. For details, please refer to Figure 1-6 , rack plates 3 are also installed on both sides of the extrusion rod 2, and a gear ring 55 is installed on the other end of the connecting ring 56, and the rack plate 3 is meshed with the gear ring 55;

[0050] The ironing device 5 further includes a square sleeve 51 provided at one end of a connecting ring 56. The square sleeve 51 is connected to the connecting ring 56 via a first spring 54. An inclined surface 57 is provided inside the base 4, and the square sleeve 51 is used to abut against the inclined surface 57.

[0051] A push plate 53 is slidably connected to the inside of the square sleeve 51, and a first spring piece 58 is installed inside the first melting block 52. One end of the first spring piece 58 is connected to the inner wall of the first melting block 52, and the other end of the first spring piece 58 is connected to one end of the second melting block 59. The push plate 53 is used to squeeze the first spring piece 58 to deform.

[0052] Drive: According to Figure 5 As shown, when the gear ring 55 drives the connecting ring 56 to rotate, the connecting ring 56 drives the square sleeve 51 to rotate. The upper end of the square sleeve 51 is provided with an inclined surface. Therefore, when the square sleeve 51 contacts the inner wall of the base 4, the base 4 squeezes the square sleeve 51 to slide to the left, and the square sleeve 51 drives the first fusing block 52 to insert into the optical fiber jumper 10 or the optical fiber head 11. Then, the connecting ring 56 continues to rotate, so that the first fusing block 52 rotates and heat-seals the outer surface of the optical fiber jumper 10 or the connecting sleeve 12 to form an annular groove.

[0053] When the first hot melting block 52 is inserted into the optical fiber jumper 10 and the optical fiber head 11, the push plate 53 at the other end of the square sleeve 51 will also abut against the inner wall of the base 4. Then, when the connecting ring 56 drives the square sleeve 51 to rotate, the push plate 53 is squeezed by the base 4 to slide to one end. Figure 5 As shown, the push plate 53 is used to squeeze the first spring piece 58. Since one side of the first spring piece 58 is connected to the inner wall of the first fusing block 52, and the other side of the first spring piece 58 is connected to one side of the second fusing block 59, the push plate 53 will squeeze the first spring piece 58 to deform, so that the deformed first spring piece 58 pushes the second fusing block 59 to slide out of the interior of the first fusing block 52, so that the second fusing block 59 heat-melts the interior of the annular groove. Example 5

[0054] This embodiment is an improvement made on the basis of embodiment 4. For details, please refer to Figure 1-7 A transmission device 7 is further provided inside the base 4. The transmission device 7 is used to drive the ring gear 55 to rotate. The transmission device 7 includes a rotating shaft 71 installed inside the base 4. A protruding block 74 is installed on one side of the rotating shaft 71, and a third spring 72 is installed on the other side of the rotating shaft 71. A gear 73 is installed on the outer surface of the third spring 72, and the gear 73 is engaged with the ring gear 55.

[0055] A second spring piece 75 is also installed inside the base 4, and the protruding block 74 is used to squeeze the second spring piece 75 to deform. An airbag ball 77 is installed inside the base 4, and one end of the airbag ball 77 is connected to the first air pipe 76, and one end of the first air pipe 76 is connected to the interior of the first piston cylinder 62.

[0056] according to Figure 7 As shown, when the ring gear 55 rotates, the ring gear 55 also drives the gear 73 to rotate, and the gear 73 drives the third spring 72 and the rotating shaft 71 to rotate. The rotating shaft 71 drives the extension block 74 to rotate, and the extension block 74 squeezes 77, so that the air inside 77 flows into the inside of the first piston cylinder 62, so that the air inside the first piston cylinder 62 squeezes the first piston rod 61 to slide to the right, and the first piston rod 61 pushes the folding plate 13 and the connecting sleeve 12 to slide between the optical fiber jumper 10 and the optical fiber head 11;

[0057] It should be noted that in order to allow the ring gear 55 to drive the ring gear 55 to rotate one circle first, so that the first melting block 52 can heat-melt an annular groove on the outer surface of the optical fiber jumper 10 or the optical fiber head 11, a second elastic piece 75 is installed inside the base 4. When the gear 73 drives the third spring 72 to rotate, the gear 73 drives the rotating shaft 71 to rotate, and the rotating shaft 71 drives the extending block 74 to rotate. The extending block 74 first contacts the second elastic piece 75, and is stretched and stored by the third spring 72, so that the ring gear 55 first drives the connecting ring 56 to rotate. The connecting ring 56 drives the first hot melting block 52 to hot-melt the outer surface of the optical fiber jumper 10 or the optical fiber head 11. When the gear ring 55 rotates one circle, its rotational force is greater than the spring force of the second spring piece 75, and the second spring piece 75 will be squeezed and deformed, so that the protruding block 74 can pass over the second spring piece 75, so that the protruding block 74 can hit the airbag ball 77. The air is transmitted to the first piston cylinder 62 through the first air pipe 76 through the airbag ball 77, so that the hot melting is achieved first and then the connecting sleeve 12 is pushed to slide between the optical fiber jumper 10 and the optical fiber head 11. Example 6

[0058] The present invention also provides a crimping method of an automatic crimping device for optical fiber jumper connectors.

[0059] S1. Pass the optical fiber jumper 10 and the optical fiber head 11 through the two ironing devices 5 so that one end of the optical fiber head 11 is inside the holder 14. At this time, the connection between the optical fiber jumper 10 and the optical fiber head 11 is located between the two ironing devices 5. The rack plate 3 is driven downward by the squeezing rod 2.

[0060] S2. Drive the gear ring 55 and the connecting ring 56 to rotate through the rack plate 3. The gear ring 55 drives the first fusing block 52 to rotate. The first fusing block 52 fuses the outer surfaces of the optical fiber jumper 10 and the optical fiber head 11, forming an annular groove on the outer surfaces of the optical fiber jumper 10 and the optical fiber head 11. Then, slide the second fusing block 59 inside the first fusing block 52 and fuse one side of the annular groove through the second fusing block 59, so that the cross section of the annular groove becomes a right angle.

[0061] S3, spraying glue to the connection between the optical fiber jumper 10 and the optical fiber head 11 through the inclined surface 57;

[0062] S4. After executing S3, slide the connecting sleeve 12 so that the two ends of the connecting sleeve 12 are located at the two annular grooves. By rotating the gear ring 55 and the first fusing block 52 again, the folding plate 13 is squeezed by the first fusing block 52 to allow the folding plate 13 to be inserted into the annular groove. Then, the second fusing block 59 inside the first fusing block 52 is extended again, and one end of the folding plate 13 is bent by the second fusing block 59 to allow the bent folding plate 13 to be inserted into the annular groove, thereby completing the fixed crimping.

[0064] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention.
