[0002] The present application relates to a fiber connector production equipment, in particular to a fiber coil transportation device based on chain link plate variable distance. As a key component in the optical fiber communication system, the fiber connector needs to precisely butt joint the fiber end face to realize efficient optical coupling. In the existing production process, the fiber cable with fixed length cutting needs to be wound into an elliptical coil and fixed by adhesive tape, and after 24 hours of standing, it enters the assembly process, including multiple links such as pre-sequencing, baking, post-sequencing, grinding and post-testing.

[0003] At present, the coil transfer between processes mainly relies on manual operation, which has the following technical defects: 1) low efficiency of manual handling, which restricts the overall production efficiency; 2) high labor cost; 3) different requirements for coil transportation distance in each process. In view of these problems, the present application uses chain link plate variable distance to realize the automatic conversion of fiber coil from dense arrangement to equal interval arrangement, which has more obvious advantages than manual operation or other transportation methods: first, the chain transmission system has simple structure, convenient maintenance and long service life; together with the three-jaw wire clamping disc, it can effectively prevent the winding and damage of the fiber coil. Second, by adjusting the installation distance of the link plate, it can flexibly adapt to the transportation distance requirements of different processes; finally, the device can effectively reduce the labor cost, improve the production efficiency and ensure the transportation precision. Therefore, we propose a fiber coil transportation device based on chain link plate variable distance to solve the above problems. SUMMARY

[0004] In order to solve the above problems, the purpose of the present application is to provide a fiber coil transportation device based on chain link plate variable distance, which solves the problems of low efficiency, slow speed and high cost, greatly improves the cable transportation efficiency and reduces the production and transportation cost.

The two sides of the main body are symmetrical, and the bottom is fixedly connected with the connecting base (302). The top of the connecting base (302) is provided with symmetrical L-shaped clamping block structures, which limit the rotation of the hanging wheel (301) in the vertical direction and maintain the spacing of adjacent hanging wheels (301) in the horizontal direction. The bottom of the connecting base (302) is provided with a rectangular parallelepiped structure with a countersunk hole and a hinge seat, which is fastened with the hanging wheel (301) through a screw. The left side is provided with a single hinge seat for fixing one end of the tension spring (305), and the right side is provided with a double hinge seat which is connected with the bearing at the bottom of the waist-shaped pushing lever (304) through the rotating shaft (303). The waist-shaped pushing lever (304) is provided with a through hole in the middle for fixing the other end of the spring (305). During the intensive arrangement of the feeding and transporting process, the L-shaped pushing piece (10) on the chain pushes the waist-shaped pushing lever (304) to rotate around the hinge seat and stretch the spring (305).

When the rectangular blocks pass through the through slot, they need to be rotated counterclockwise by a corresponding angle. The three-way linkage driving disc (403) is lifted by the compression spring (405) and clamped in the driving disc limiting shell (404), so as to realize the fixation and limiting of the three-way linkage driving disc (403). The compression spring (405) is installed between the wire clamping disc base (401) and the three-way linkage driving disc (403); during feeding, the down coil makes the clamp claw linkage rotate, the driving disc moves downward to drive the remaining clamp claws to rotate synchronously, so that the optical fiber coil is sleeved at the non-slip groove of the short side of the clamp claw.

When the piston rod of the pen-shaped cylinder (801) pushes the second stop block (807) to extend and block, the first stop block (806) is reversely retracted through gear and rack transmission, and the hanging assembly (3) closest to the gate is pushed to the middle position between the two stop blocks.

[0031] The working process of the optical fiber coil conveying device based on the chain shifting piece variable pitch will be described below in combination with the accompanying drawings.

[0032] As shown in Figure 3 , 4 , 5, 6: The three-jaw wire clamping disc (4) is installed below the hanging assembly (3).

Subsequently, the assembled assembly enters the dense arrangement feeding conveying power module (1), the L-shaped shifting piece (10) on the chain pushes the waist-shaped shifting lever (304) to rotate around the hinge seat and stretch the spring (305). When the force balance is reached, the L-shaped shifting piece (10) drives the hanging assembly (3), the three-jaw wire clamping disc (4), and the optical fiber coil to move synchronously until the hanging assembly (3) is blocked by the double-bar gate (8) or the adjacent assembly.

First, the hanging component (3) is densely arranged on the left side of the first block (806) of the double-pole gate (8), and when the piston rod of the pen-shaped cylinder (801) is pushed out to drive the second block (807) to move, the first block (806) is retracted through the gear and rack transmission. Because the densely arranged hanging components (3) are always pushed forward by the L-shaped tab (10) on the chain, the first hanging component (3) will be pushed into the left side of the second block (807). Then, the second block (807) is retracted, and the first block (806) is extended in reverse. The remaining hanging components (3) will be blocked by the first block (806). Then the pen-shaped cylinder (905) of the power connection module (9) pushes the piston rod to drive the polyurethane push rod (909) to move, and pushes the single hanging component (3) to the equal-interval arrangement production and transportation power module. Repeating this process will separate the densely arranged hanging components (3) one by one into equal-interval transport. When the equal-interval production and transportation are carried out, the L-shaped tab (10) directly acts on the left side of the connecting base (302) plane to realize the equal-interval continuous transportation of the hanging component (3); during the whole process, the elastic properties of the polyurethane push rod (909) ensure that it can bend and deform and automatically reset when encountering obstacles, ensuring the continuity and stability of the transportation process.
