Description

Technical Field

[0001] The utility model relates to the technical field of automation equipment, in particular to a full-automatic fiber stripping and threading machine. Background Art

[0002] As we all know, fiber optic patch cords are jumpers used in fiber optic communication systems, fiber optic access networks, fiber optic data transmission, local area networks and other fields. They include optical fiber lines and connectors. Before assembling the optical fiber lines and connectors, the coating at the fiber tails on the optical fiber lines needs to be stripped and cut. This process is called fiber stripping.

[0003] Large-scale fiber stripping is generally performed using a fiber stripping machine. Existing fiber stripping machines, for example, China Invention CN201010258795.8, discloses an automatic fiber stripping machine, whose main structure is: the motor is controlled to rotate by a control circuit, first the fiber drawing device clamps the optical fiber and moves to a set working position for cutting the outer skin, controls the outer skin cutting device to cut the outer skin, then the fiber drawing device clamps the optical fiber and moves to a set working position for cutting the Kevlar wire, controls the Kevlar wire cutting device to cut the Kevlar wire, and finally the fiber drawing device clamps the optical fiber and moves to a set working position for cutting the inner skin, controls the inner skin cutting device to cut the inner skin to expose the fiber core. Although the above-mentioned fiber stripping machine can strip the coating of the optical fiber, the subsequent operations of cutting the optical fiber to a certain length and inserting the ceramic ferrule are all manually operated, which not only has low production efficiency and high labor cost, but also does not perform inspection, resulting in a low yield rate. Therefore, the above-mentioned defects are very obvious. For this reason, we propose a fully automatic fiber stripping and inserting machine to solve the above-mentioned problems.

[0031] like Figures 1 to 8 As shown, the present embodiment provides a fully automatic fiber stripping and threading machine, comprising a workbench 1, on which are provided a loading mechanism 2 for supplying raw materials of an optical fiber line 81, a tensioning control mechanism 3 for tensioning the optical fiber line 81, a wire feeding mechanism 4 for discharging the optical fiber line 81, a fiber threading mechanism 5 for clamping the optical fiber line 81 and moving and rotating it, a fiber stripping mechanism 6 for stripping the coating of the end of the optical fiber line 81, a moving holding mechanism 7 for placing and moving the external ceramic ferrule 80, a ferrule mechanism 8 for inserting the lower end of the optical fiber line 81 into the inner hole of the ceramic ferrule 80, an upper fiber cutting mechanism 9 for determining the length of the optical fiber line 81 and cutting it, and a lower fiber cutting mechanism 10 for cutting and discarding defective optical fiber lines 81. The workbench 1 is provided with a host 11 for controlling the orderly operation of the system.

[0032] When the present embodiment is actually working, the material is supplied by the feeding mechanism 2, the tensioning control mechanism 3 tensions the optical fiber 81, the feeding mechanism 4 arranges and feeds the optical fiber 81, the fiber insertion mechanism 5 clamps the optical fiber 81 and moves and rotates, the fiber stripping mechanism 6 strips the end of the optical fiber 81, the mobile holding mechanism 7 places and moves the ceramic ferrule 80, the ferrule mechanism 8 inserts the optical fiber 81 into the ceramic ferrule 80, the upper fiber cutting mechanism 9 cuts the optical fiber 81 to a set length, and the lower fiber cutting mechanism 10 cuts and discards the defective optical fiber 81, thereby realizing the fully automatic operation of stripping the optical fiber, cutting to a fixed length, and inserting the ceramic ferrule 80, effectively improving the production efficiency of the optical fiber jumper, and only a small amount of manual loading and taking of materials is required, which liberates labor and saves labor costs. In addition, in the above operations, sensors are also used to detect the waste optical fiber 81, which effectively improves the yield rate and improves the product quality, thereby greatly meeting the actual use needs of users.

[0033] Furthermore, the loading mechanism 2 of the present embodiment includes a right-angle seat 12 and a cantilever shaft 13 installed inside the workbench 1. The cantilever shaft 13 is connected to the right-angle seat 12 by a through-shaft. A fiber optic winding drum 14 is mounted on one end of the cantilever shaft 13. Both ends of the fiber optic winding drum 14 are clamped on the cantilever shaft 13 by nuts 15. A light source is provided in the fiber optic winding drum 14 to provide bright light to the starting end of the optical fiber line 81 on the fiber optic winding drum 14. A first cylinder 16 is installed on the right-angle seat 12. A brake block 17 adapted to touch the circumferential side surface of the other end of the cantilever shaft 13 is provided on the push rod of the first cylinder 16. Therefore, the optical fiber winding reel 14 can provide the optical fiber line 81 for the whole machine. Since the optical fiber line 81 has excellent light guiding characteristics, a light source is placed at the starting end of the optical fiber line 81, and the light emitted by the reflective light source can be received at the end of the optical fiber line 81. The light source can provide bright light for the subsequent photosensor 73 to detect the good condition of the optical fiber line 81. At the same time, when the optical fiber line 81 in the optical fiber winding reel 14 is used up, the user can remove the nut 15 and replace it with a new optical fiber winding reel 14, which is convenient for the user to load the material; the push rod of the first cylinder 16 drives the brake block 17 to control the rotation of the cantilever shaft 13, and then controls the feeding length of the optical fiber winding reel 14, which is convenient for the tensioning control mechanism 3 to control the tensioning of the optical fiber line 81.

[0034] Furthermore, the tensioning control mechanism 3 of the present embodiment includes a fixed frame 18 installed on the surface of the workbench 1, and the front and rear ends of the fixed frame 18 are respectively provided with a first fixed pulley 19 and a second fixed pulley 20. A feeding port 21 is provided on the surface of the workbench 1 and located at the lower end of the first fixed pulley 19. The optical fiber winding drum 14 is located at the lower end of the feeding port 21. The optical fiber line 81 on the optical fiber winding drum 14 passes through the feeding port 21 and is sequentially wound around the first fixed pulley 19 and the second fixed pulley 20. A movable pulley 22 is hung on the optical fiber line 81 between the first fixed pulley 19 and the second fixed pulley 20, and a weight 23 is hung on the ear seat of the movable pulley 22. The first light curtain sensor 24 and the second light curtain sensor 25 are installed on the two opposite side walls of the inner cavity of the fixed frame 18, and the movable pulley 22 and the weight 23 are suspended between the sensing areas of the first light curtain sensor 24 and the second light curtain sensor 25. Therefore, when the wire feeding mechanism 4 pulls the optical fiber line 81 on the optical fiber winding drum 14 and is pulled too tight by the wire feeding mechanism 4, under the pulling force of the optical fiber line 81, the movable pulley 22 and the weight 23 will move upward and touch the sensing area of ​​the first light curtain sensor 24, and the first light curtain sensor 24 sends a signal to the host 11, and the host 11 controls the push rod of the first cylinder 16 to drive the brake block 17 to move downward, releasing the top contact and braking of the cantilever shaft 13. At this time, the optical fiber winding drum 14 is pulled by the pulling force of the light, so that the movable pulley 22 and the weight 23 are suspended between the sensing areas of the first light curtain sensor 24 and the second light curtain sensor 25; when the wire feeding mechanism 4 pulls the optical fiber line 81 on the optical fiber winding drum 14 1, and is pulled too loose by the wire feeding mechanism 4, under the action of gravity, the movable pulley 22 and the weight 23 will move downward and touch the sensing area of ​​the second light curtain sensor 25, and the second light curtain sensor 25 will send a signal to the host 11, and the host 11 controls the push rod of the first cylinder 16 to drive the brake block 17 to move upward, and the brake block 17 touches the cantilever shaft 13 and brakes. At this time, the wire feeding mechanism 4 pulls the optical fiber line 81 on the optical fiber winding drum 14, so that the movable pulley 22 and the weight 23 are suspended between the sensing areas of the first light curtain sensor 24 and the second light curtain sensor 25, thereby effectively adjusting the tension of the optical fiber line 81 between the optical fiber winding drum 14 and the wire feeding mechanism 4, and realizing automatic tension control.

[0035] Further, the wire feeding mechanism 4 of the present embodiment includes a gantry 26 and a first motor 27 and a second motor 28 installed on the surface of the workbench 1.

The optical fiber line on the second fixed pulley 20 is connected to the first motor 27 and the second motor 28 is connected to the second rubber-coated rollers 31 by transmission. 81 is wound around the third fixed pulley 29, turns downward and passes through the two first rubber-coated rollers 30 and the two second rubber-coated rollers 31 and the inner hole of the guide tube 32 in sequence to be discharged. At the same time, the two first rubber-coated rollers 30 and the second rubber-coated rollers 31 can clamp the optical fiber line 81; during the wire feeding operation, firstly, when the first motor 27 drives one of the first rubber-coated rollers 30 to rotate and the second motor 28 drives one of the second rubber-coated rollers 31 to rotate, the optical fiber line 81 is clamped in the two first rubber-coated rollers 30 and the two second rubber-coated rollers 31, and is conveyed and discharged through the inner hole of the guide tube 32, thereby realizing the pulling and feeding of the optical fiber line 81 on the optical fiber winding drum 14, and the first sensor 33 can detect whether the optical fiber line 81 is discharged from the outlet of the guide tube 32.

At the bottom of the inner hole of the porcelain ferrule 80, since a light source is placed at the starting end of the optical fiber 81, the front end of the optical fiber 81 can receive the light emitted by the reflective light source. When the light exposed at the front end of the optical fiber 81 is detected by the photosensor 73, it is a good product. If the light exposed at the front end of the optical fiber 81 is not detected, it is a defective product. Then the host 11 controls the slide of the fifth linear module 70 to drive the clamp of the third finger cylinder 75 and the clamp of the fourth finger cylinder 77 to move and clamp the front end of the optical fiber 81. The second pneumatic scissors 76 cuts the optical fiber 81 between the clamp of the third finger cylinder 75 and the clamp of the fourth finger cylinder 77.
