Description

[0046] Example 2:

[0047] A fiber collecting and arranging mechanism comprises an equipment frame assembly, a touch screen assembly, a fiber pressing and cutting cylinder assembly, a fiber arranging and switching disk assembly, a fiber collecting assembly, and a dancing wheel panel assembly.

[0048] The equipment frame is mainly used for the appearance of the entire equipment and the platform supporting the entire internal structure.

[0049] The touch screen component is mainly used for various online operations of the equipment, and displays various parameters and equipment operating status in real time. Important data can be recorded;

[0050] The fiber pressing + cutting cylinder assembly is mainly used for pressing and cutting optical fibers. The fiber pressing mechanism is installed between the two take-up reels and consists of two sets of pneumatic mechanisms. One set moves up and down to press the optical fiber to the specified position, and the other set moves forward and backward to push the optical fiber to the fiber cutting position.

[0051] The fiber arrangement + switching disk assembly is mainly used for arranging the optical fiber disk, and its main function is to provide optical fiber arrangement transmission and the switching and fiber taking-up functions of A and B optical fiber disks; the mechanism adopts two sets of high-precision modules and fiber guide wheels. The disk changing mechanism is installed above the take-up disk. When the disk needs to be changed, the motor drives the disk changing guide wheel assembly installed on the module slide to move left and right through the lead screw, thereby dragging the optical fiber to the specified position, and cooperating with the fiber pressing mechanism and the cutting mechanism to realize the replacement of the optical fiber disk. It is set to the pitch requirement of the optical fiber diameter range, and the guide wheel assembly is wound back and forth on the fiber arrangement module to the optical fiber disk for fiber taking-up.

It consists of a pair of three-wheel groups and a two-wheel group, as well as tension control (using dancing wheels, non-damping cylinders and distance sensors for tension control, and the tension control assembly is integrated on a vertical panel).

[0054] The working principle is: first, the optical fiber at the end of the drawing tower is manually wound on the left optical fiber clamp of the optical fiber reel, and the winding fiber length of coil A is set on the HIM. The fiber arrangement + switching disk assembly starts to be wound on the 300km optical fiber reel A according to the stroke set by the program. The fiber collection motor starts to drive the 300km optical fiber reel A to rotate and complete the winding. Then, the switching disk assembly is moved to the limit stop set at the B reel through the transverse module transmission. The fiber pressing + cutting cylinder assembly starts to move, presses the optical fiber into the right clamp and cuts it off through the right blade. The fiber arrangement + switching disk assembly starts to be wound on the 300km optical fiber reel B according to the stroke set by the program. At the same time, the wound 300km optical fiber reel A is removed and the empty optical fiber reel is installed. In this way, the two optical fiber reels are switched back and forth to collect the fiber.
