Description

Technical Field

[0001] The invention relates to the technical field of automation equipment, in particular to a fully automatic loose-piece threading device for optical fiber jumpers and a fully automatic loose-piece threading method for optical fiber jumpers. Background Art

[0002] As we all know, optical fiber is the abbreviation of optical fiber, which is a fiber made of glass or plastic that can be used as a light transmission tool. The transmission principle is "total reflection of light". Optical fiber communication has the advantages of wide bandwidth, strong anti-interference ability, high fidelity, reliable working performance and low cost, so optical fiber communication is now widely popular.

[0003] Among them, the fiber optic patch cord is used to make a jumper from the equipment to the fiber optic wiring link. The fiber optic patch cord is a common connecting line between the optical terminal and the terminal box, so the demand is very large. There are multiple loose parts installed in series on the fiber optic patch cord, and these loose parts include tail sleeves, retaining rings and springs. The loose parts on the existing fiber optic patch cord are mostly threaded on a manual assembly line. These individual loose parts are manually threaded into the optical fiber one by one. Due to long-term manual operation, it is easy to get the arrangement order of the loose parts wrong, and it is easy to miss loose parts. In addition, the loose parts on the fiber optic patch cord are very small, and the optical fiber of the fiber optic patch cord itself must be long and thin. Therefore, the manually produced fiber optic patch cord not only has a high defective rate, but also it is very difficult to manually thread the loose parts, resulting in low production efficiency and high labor costs. Therefore, it is necessary to design a device for fully automatic threading of loose parts of fiber optic patch cords. Summary of the invention

[0014] Preferably, the method for fully automatic threading of loose parts of optical fiber jumpers comprises the following steps:

[0015] S1. Fiber optic patch cord loading, the front end of a bundle of fiber optic patch cords horizontally placed on the support sheet metal;

[0016] S2. The material suction alignment is performed by inserting the "V"-shaped groove at the bottom of the material taking block into a bundle of fiber optic jumpers at the material support sheet metal, and then the suction nozzle at the bottom of the "V"-shaped groove sucks one of the fiber optic jumpers in a bundle, and the first pneumatic finger and the suction nozzle synchronously clamp the fiber optic jumper, and finally move it to the wire pressing groove between the upper rubber-coated roller and the lower rubber-coated roller and press it, and at the same time, the front end of the fiber optic jumper is aligned and inserted into the first semicircular wire groove and the second semicircular wire groove;

[0017] S3.

[0018] S4. The optical fiber jumper is threaded through the loose parts, and the suction nozzle and the first pneumatic finger are used to loosen the grip of the optical fiber jumper. Then, the upper rubber-coated roller and the lower rubber-coated roller rotate synchronously and drive the front end of the optical fiber jumper to pass through the inner cavity of the tail sleeve, the stop ring and the spring in sequence.

Finally, when the front end of the optical fiber jumper moves forward, it touches the second guide surface and then deflects and extends out.

Therefore, the optical fiber jumper is automatically threaded with loose parts through the steps of optical fiber jumper loading, material suction alignment, loose parts alignment, optical fiber jumper threading loose parts, and optical fiber jumper unloading in sequence. The process only requires the operator to put a bunch of fiber optic patch cords without loose parts into the feeding end, and then the device repeats the cycle to complete the fully automatic loose parts threading, and the operator can harvest a bundle of fiber optic patch cords with loose parts threaded at the unloading end, without the operator having to perform complex and delicate loose parts threading operations. The device can quickly, cleverly and accurately set the tail sleeve, stop ring and spring with a smaller volume on the fiber optic patch cord with an extremely fine diameter, and complete the neat stacking of the finished fiber optic patch cords. The entire loose parts threading process does not require manual intervention and is completed fully automatically by the device. It only takes a few seconds to complete the loose parts threading of a fiber optic patch cord, and the error rate of each mechanism is low, and there will be no missing parts. Therefore, the finished product rate of the loose parts threading of the fiber optic patch cord is effectively improved, and the efficiency of the loose parts threading of the fiber optic patch cord is greatly improved, the cost of the fiber optic patch cord is reduced, and the large demand for fiber optic patch cords on the market is met, which is conducive to the rapid popularization of China's optical fiber communication; at the same time, the entire loose parts threading process only requires one operator to complete both the material placement and the material collection, saving labor costs, and its structure is simple, the manual operation is convenient, and it has strong practicality.

[0037] Furthermore, the direct vibration mechanism 12 of this embodiment includes a linear feeder 61 fixed on the workbench 1 and a feed plate 62 installed on the vibration end of the linear feeder 61, and the upper end surface of the feed plate 62 is provided with a first feed groove 63 and a second feed groove 64, and the notches at one end of the first feed groove 63 and the second feed groove 64 are connected with the first positioning groove 45 and the second positioning groove 46 in turn, and the other end is connected with the discharge ports of the first vibration disk 6 and the second vibration disk 7 in turn, and the linear feeder 61 is installed with a pushing block 66 through the pushing head of the seventh cylinder 65, and one end of the pushing block 66 is movably inserted in the sliding groove 48, and the side of the sliding groove 48 is provided with a connecting hole 67 connected with the discharge port of the third vibration disk 8.

[0038] Furthermore, the unloading mechanism 5 of the present embodiment includes a third fixed bracket 68 fixed on the workbench 1, and the third fixed bracket 68 is installed with a third movable bracket 70 through the rotating head of the rotary cylinder 69, and a second pneumatic finger 71 is installed at the lower end of the third movable bracket 70 and located at the second guide surface 60, and an eighth cylinder 72 and a second linear slide rail module 73 are horizontally installed on the workbench 1 and located at the third fixed bracket 68, and a unloading box 74 is installed on the upper end of the slider of the second linear slide rail module 73, and the pushing head of the eighth cylinder 72 is connected to the unloading box 74, and a second notch portion 75 is provided at one end of the unloading box 74 and located at the second pneumatic finger 71.

[0039] Furthermore, the vertical height of one side of the side wall of the "V"-shaped groove 26 of this embodiment is higher than that of the other side (such as Figure 4 As shown in the figure, the width of the suction nozzle 27 is 0.1 mm to 1 mm. Therefore, by setting the vertical height of one side of the side wall of the "V"-shaped groove 26 higher than the other side, when the "V"-shaped groove 26 is inserted into a bundle of optical fiber jumpers 76, a part of the optical fiber jumpers 76 will be discharged from the side with a lower side wall of the "V"-shaped groove 26, and will not be sucked by the suction nozzle 27, so that the number of optical fiber jumpers 76 in the "V"-shaped groove 26 is relatively small at this time, and the number of optical fiber jumpers 76 near the suction nozzle 27 is effectively reduced. When the suction nozzle 27 absorbs the optical fiber jumpers 76 in the "V"-shaped groove 26, only a single optical fiber jumper 76 is absorbed by the suction nozzle 27 at the bottom of the "V"-shaped groove 26; at the same time, the width of the suction nozzle 27 is designed to be narrow, so that the suction nozzle 27 can only absorb one optical fiber jumper 76 at a time, preventing the suction nozzle 27 with a larger width from sucking multiple optical fiber jumpers 76 at a time, effectively solving the problem of the suction nozzle 27 sucking multiple fiber jumpers at a time, and improving production efficiency.

[0040] Furthermore, one end of the support sheet metal 18 of this embodiment is in a "U" shape. By using the "U"-shaped support sheet metal 18, the front end of a bundle of optical fiber jumpers 76 can be stably and horizontally placed on the support sheet metal 18, which is convenient for storing and loading a bundle of optical fiber jumpers 76, and can also increase the number of optical fiber jumpers 76 released, effectively improving production efficiency.

[0041] Further, the detailed method for fully automatic threading of the optical fiber jumper 76 of this embodiment includes the following steps:

[0042] S1. The fiber optic patch cord 76 is loaded, and a metal part (not shown) is installed at the rear end of the fiber optic patch cord 76. The rear end of a bundle of fiber optic patch cords 76 is placed in the loading box 16, and the front end of the fiber optic patch cord 76 is horizontally placed on the support sheet metal 18;

[0043] S2. Suction alignment: the dragging head of the first cylinder lifts the front end of the optical fiber jumper 76 upward through the supporting sheet metal 18 and aligns it horizontally with the lower rubber-coated roller 31. The material taking block 25 is located at the initial position. The pushing head of the third cylinder 23 pushes the material taking block 25 at one end of the buffer suction rod 24 to the optical fiber jumper 76 at the supporting sheet metal 18. At this time, the side wall of the "V"-shaped groove 26 of the material taking block 25 is inserted at the front end of a bundle of optical fiber jumpers 76, and the suction nozzle 27 at the bottom of the "V"-shaped groove 26 is inserted at the front end of the bundle of optical fiber jumpers 76. After the fiber optic patch cord 76 is sucked from a bundle of fiber optic patch cords 76, the pushing head of the third cylinder 23 drives the fiber optic patch cord 76 to move upward through the material taking block 25. At the same time, the first pneumatic finger 28 clamps the fiber optic patch cord 76 at the suction nozzle 27. The use of the first pneumatic finger 28 to clamp the fiber optic patch cord 76 can effectively prevent the suction nozzle 27 from falling off when driving the fiber optic patch cord 76 to move. The fourth cylinder 32 pushes the upper rubber-coated roller 33, the first guide block 34 and the upper guide block 43 to move downward. The upper guide block 43 and the lower guide block 39 are aligned with each other. The first semicircular wire groove 42 and the second semicircular wire groove 44 form a complete funnel-shaped inner cavity. The first notch 36 is horizontally aligned with the first semicircular wire groove 42 and the second semicircular wire groove 44. At this time, the third cylinder 23 pushes the fiber optic patch cord 76 sucked from the suction nozzle 27 forward to the wire pressing groove 38 between the upper rubber-coated roller 33 and the lower rubber-coated roller 31 through the first moving frame 22. Under the thrust of the third cylinder 23, the suction The front end of the optical fiber jumper 76 sucked by the nozzle 27 is inserted into the first notch 36 through the guiding effect of a group of first guide surfaces 35. At the same time, the front end of the optical fiber jumper 76 sucked by the nozzle 27 is inserted into the first semicircular wire groove 42 and the second semicircular wire groove 44. Under the thrust of the fourth cylinder 32, the upper rubber-coated roller 33 presses down the lower rubber-coated roller 31, and the front end of the optical fiber jumper 76 is clamped in the wire pressing groove 38 between the upper rubber-coated roller 33 and the lower rubber-coated roller 31.

[0044] S3. Alignment of parts. The first vibration plate 6, the second vibration plate 7 and the third vibration plate 8 respectively transport the tail sleeve 9, the stop ring 10 and the spring 11 to the first feed trough 63, the second feed trough 64 and the slide trough 48. The linear feeder 61 transports the tail sleeve 9 and the stop ring 10 in the first feed trough 63 and the second feed trough 64 to the first positioning groove 45 and the second positioning groove 46. At the same time, the seventh cylinder 65 pushes the push block 66 and pushes the spring 11 in the slide trough 48 to the third positioning groove 47. The fifth cylinder 49 pushes the limit plate 50 downward and presses the tail sleeve 9, the stop ring 10 and the spring 11 downward to the first positioning groove 45, the second positioning groove 46 and the third positioning groove respectively. In the positioning groove 47, the sixth cylinder 54 pushes the first limiting head 56 and the second limiting head 57 through the moving block 55 and touches the sides of the tail sleeve 9 and the stop ring 10 in the first positioning groove 45 and the second positioning groove 46, so that the tail sleeve 9, the stop ring 10 and the spring 11 are respectively limited in the first positioning groove 45, the second positioning groove 46 and the third positioning groove 47. At the same time, the tail sleeve 9, the stop ring 10 and the spring 11 are coaxially aligned in series in sequence, and the tail sleeve 9, the stop ring 10 and the spring 11 are coaxially aligned with the front end of the optical fiber jumper 76 in the first semicircular wire groove 42 and the second semicircular wire groove 44. The first sensor 58 can detect whether the spring 11 in the third feed trough is pushed in place.

[0045] S4. The optical fiber jumper 76 is threaded through the loose parts. The host 13 controls the suction nozzle 27 and the first pneumatic finger 28 to release the clamping of the optical fiber jumper 76. At the same time, the rotating shaft of the motor 30 drives the lower rubber-coated roller 31 to rotate, and the upper rubber-coated roller 33 is driven to rotate synchronously under the action of friction force, and the pressing groove 38 between the upper rubber-coated roller 33 and the lower rubber-coated roller 31 is driven to drive the front end of the optical fiber jumper 76 to move forward, and the front end of the optical fiber jumper 76 is inserted into the inner cavity of the tail sleeve 9, the stop ring 10 and the spring 11 in the first positioning groove 45, the second positioning groove 46 and the third positioning groove 47 in sequence, and after the front end of the optical fiber jumper 76 passes through the tail sleeve 9, the stop ring 10 and the spring 11 in sequence, The front end of the optical fiber jumper 76 continues to move forward and deflects after contacting the second guide surface 60, and extends out of the second guide surface 60. The second sensor 59 senses the front end of the optical fiber jumper 76 and sends a signal to the host 13. The host 13 controls the motor 30 to stop rotating, and controls the second cylinder 21, the third cylinder 23, the fourth cylinder 32, the fifth cylinder 49, the sixth cylinder 54, and the seventh cylinder 65 to retreat and reset. At this time, the front end of the optical fiber jumper 76 completes the threading operation of the tail sleeve 9, the stop ring 10, and the spring 11, and the optical fiber jumper 76, the tail sleeve 9, the stop ring 10, and the spring 11 are released from the limit, and the front end of the optical fiber jumper 76 is located at the second pneumatic finger 71;

[0046] S5. The optical fiber jumper 76 is unloaded. The main machine 13 controls the claws of the second pneumatic finger 71 to clamp the front end of the optical fiber jumper 76 at the second guide surface 60. The rotating head of the rotary cylinder 69 rotates and swings the optical fiber jumper 76 clamped on the second pneumatic finger 71 through the third moving frame 70 to rotate and drag it forward. The metal part at the rear end of the optical fiber jumper 76 drives the tail sleeve 9, the stop ring 10 and the spring 11 inserted in the optical fiber jumper 76 to move together. The second pneumatic finger 71 drives the optical fiber jumper 76 to pass through the second notch 75 and be dragged into the unloading box 74. The claws of the second pneumatic finger 71 open and the front end of the optical fiber jumper 76 is placed on the side of one end of the unloading box 74. The tail sleeve 9, the stop ring 10 and the spring 11 inserted in the optical fiber jumper 76 are pushed to the metal part at the rear end of the optical fiber jumper 76 by the gravity acceleration of the rotation of the rotary cylinder 69. The eighth cylinder 72 drives the unloading box 74 to move synchronously with the second pneumatic finger 71.

[0047] When the present embodiment is actually working, first, the suction nozzle 27 sucks up one of the optical fiber jumpers 76 and moves it to the wire pressing groove 38 between the upper rubber-coated roller 33 and the lower rubber-coated roller 31, and then the tail sleeve 9, the stop ring 10 and the spring 11 are sequentially conveyed to the first positioning groove 45, the second positioning groove 46 and the third positioning groove 47 by the first vibration plate 6, the second vibration plate 7, the third vibration plate 8 and the linear feeder 61, and are pressed down by the limit plate 50 to be positioned, and the tail sleeve 9, the stop ring 10 and the spring 11 are coaxially aligned with the first semicircular wire groove 42, and then the motor 30 drives the upper rubber-coated roller 33 and the lower rubber-coated roller 31 to move the tail sleeve 9, the stop ring 10 and the spring 1 ... The rubber roller 31 rotates and pushes the front end of the optical fiber jumper 76 clamped in the wire pressing groove 38 forward, and the front end of the optical fiber jumper 76 passes through the first semicircular wire groove 42 and the second semicircular wire groove 44 and is inserted into the aligned tail sleeve 9, the stop ring 10 and the spring 11 cavity in sequence. Finally, when the front end of the optical fiber jumper 76 moves forward, it touches the second guide surface 60 and then deflects and extends out. The clamping claw of the second pneumatic finger 71 drags the optical fiber jumper 76 that has been threaded with loose parts into the unloading box 74. Therefore, the optical fiber jumper 76 is sequentially threaded through the fiber jumper, suction alignment, loose parts alignment, fiber jumper threading, and optical fiber. The jumper unloading step completes the fully automatic threading of the optical fiber jumper 76. The entire process only requires the operator to put a bundle of optical fiber jumpers 76 without threading into the loading end, and then the device repeats the cycle to complete the fully automatic threading. The operator can harvest a bundle of optical fiber jumpers 76 with threading completed at the unloading end. The operator does not need to perform complex and delicate threading operations. The device can quickly and accurately set the small tail sleeve 9, the stop ring 10 and the spring 11 on the optical fiber jumper 76 with an extremely fine diameter, and complete the stacking of the finished optical fiber jumpers 76. The entire threading process does not require manual intervention. The device is fully automatic, and it only takes a few seconds to thread a fiber optic patch cord 76. In addition, the error rate of each mechanism is low, and there will be no missed parts. Therefore, the yield rate of fiber optic patch cords 76 threading loose parts is effectively improved, and the efficiency of fiber optic patch cords 76 threading loose parts is greatly improved, and the cost of fiber optic patch cords 76 is reduced, which meets the large demand for fiber optic patch cords 76 in the market and contributes to the rapid popularization of fiber optic communications in China. At the same time, the entire process of threading loose parts only requires one operator to complete both material placement and material collection, saving labor costs. It has a simple structure, convenient manual operation, and is very practical.
