[0030] This invention provides an optical fiber winding device, comprising a first optical fiber winding disc 101 and a second optical fiber winding disc 102 symmetrically arranged.

A toggle disc 113 is rotatably mounted on the shielding rod support plate 107. The toggle disc 113 is coaxially arranged with the shielding rod support plate 107.

A drive shaft 115 is fixedly mounted on the toggle disc 113 via a toggle bracket 114. The drive shaft 115 is coaxially arranged with the toggle disc 113.

The magnetic friction rotating plate 116 and the magnetic friction swing plate 117 are magnetically engaged. The hollow rotating shaft 305 is magnetically engaged with the magnetic friction swing plate 117.

[0031] The drive assembly includes a rotating disk 301, a sliding rod bracket 103 fixedly mounted on the rotating disk 301, the rotating disk 301 rotatably mounted on a limiting barrel 303, and a limiting frame 302 rotatably mounted inside the limiting barrel 303. The limiting frame 302 has symmetrically arranged limiting inclined surfaces 3021 and limiting vertical surfaces 3022. Limiting posts 307 are overlapped on both limiting inclined surfaces 3021. A leaf spring 308 is provided between the limiting posts 307 and the limiting vertical surfaces 3022. An unlocking pin 306 is overlapped between the two limiting posts 307.

[0033] The working principle of the optical fiber winding device disclosed in this invention is as follows: One end of the optical fiber is inserted into the gap between the first optical fiber winding disk 101 and the second optical fiber winding disk 102. Then, the drive motor 311 is started. The output shaft of the drive motor 311 drives the spline pulley 309 to rotate through the transmission belt 310. The rotation of the spline pulley 309 drives the hollow rotating shaft 305 to rotate. The rotation of the hollow rotating shaft 305 drives the unlocking pin support disk 304 to rotate (at this time, the first optical fiber winding disk 101 and the second optical fiber winding disk 102 are not at their highest points, also...). The lower surface of the magnetic friction rotating plate 116 and the magnetic friction oscillating plate 117 are not completely magnetically attracted and adhered. There is a gap between the magnetic friction rotating plate 116 and the magnetic friction oscillating plate 117, and the magnetic attraction force is also reduced. Since they are in point contact at this time, the friction force is very small. Therefore, the magnetic friction oscillating plate 117 does not restrict the rotation of the magnetic friction rotating plate 116. The rotation of the hollow rotating shaft 305 will drive the transmission shaft 115 to rotate together. At this time, all the blocking rods 112 are in the extended state, and the position of the magnetic friction oscillating plate 117 is as follows: Figure 11 As shown), the rotation of the unlocking pin support plate 304 will cause the unlocking pin 306 to rotate. The rotation of the unlocking pin 306 will cause one of the limiting posts 307 to move along the limiting inclined plane 3021 towards the limiting vertical plane 3022. This will cause the squeezing force of the inner wall of the limiting barrel 303 on the limiting post 307 to disappear, and the friction will also disappear. The other limiting post 307 will be subject to the friction of the limiting barrel 303 and will also make the same movement. At this time, the unlocking pin 306 squeezes one of the limiting posts 307, and then drives the limiting frame 302 to rotate. The rotation of the limiting frame 302 will drive the rotating plate 301 to rotate. The rotation of the rotating plate 301 will drive the sliding rod bracket 103 to rotate. The rotation of the sliding rod bracket 103 will drive the first optical fiber winding plate 101 and the second optical fiber winding plate 104 through the sliding rod 104. 02. When the rotating disk 301 rotates, the optical fiber can be coiled on the first optical fiber coiling disk 101 and the second optical fiber coiling disk 102. The traction stress of the optical fiber will be applied to the first optical fiber coiling disk 101 and the second optical fiber coiling disk 102 as a reaction force. Therefore, when the rotating disk 301 rotates, the limiting frame 302 cannot rotate. This is because the limiting barrel 303 is a fixed part. When the limiting frame 302 rotates, one of the limiting posts 307 will be moved towards the unlocking pin 306 by the friction force of the limiting barrel 303. This causes the limiting inclined surface 3021 and the limiting barrel 303 to squeeze the limiting post 307, which increases the friction between the three and thus jams the limiting frame 302. The limiting frame 302 cannot rotate, preventing the optical fiber from becoming loose during the coiling process.

[0034] After winding is completed, the wound optical fibers are bound together by a binding machine through openings (e.g., V-shaped, semi-circular, or rectangular) on the first optical fiber winding disc 101 and the second optical fiber winding disc 102 (two binding machines can be set up and arranged symmetrically; two openings are also required on the first optical fiber winding disc 101 and the second optical fiber winding disc 102). The extension rod of the electric cylinder 204 is controlled; when the extension rod retracts, it drives the first connecting rod 205 to move. The first connecting rod 205 pulls the angle between the second connecting rod 206 and the third connecting rod 207, making the rotating disc support 208 move downwards; conversely, the rotating disc support 208 moves upwards. The movement of the rotating disk support 208 causes the first fiber winding disk 101 and the second fiber winding disk 102 to move up and down. At this time, the first fiber winding disk 101 and the second fiber winding disk 102 move downwards, so the wound fiber is blocked by the unloading table 202 and separates from the surfaces of the first fiber winding disk 101 and the second fiber winding disk 102. It should be noted that at this time, the hollow rotating shaft 305 moves upwards, causing the end face of the magnetic friction oscillating plate 117 to come into contact with the end face of the magnetic friction rotating plate 116. At this time, the magnetic friction oscillating plate 117 and the magnetic friction rotating plate 116 are magnetically attracted, thus generating friction. When the hollow rotating shaft 305 rotates, the transmission shaft 115 cannot rotate. Since the hollow rotating shaft 305 drives the first fiber winding disk 101 and the second fiber winding disk 102 to rotate (including the blocking rod support disk 107), the transmission shaft 115 will have relative movement with them. Since the transmission shaft 115 is fixed to the actuating disk 113... Therefore, the actuating disk 113 will move relative to the blocking rod support disk 107. At this time, the sliding pin 109 will slide in the actuating groove 1131, and then drive the driving slider 108 to slide on the slide rail 1071. At this time, the driving slider 108 drives the blocking swing arm 111 to swing through the driving rod 110. The swing of the blocking swing arm 111 will drive the blocking rod 112 to swing, so that the blocking rod 112 retracts below the blocking rod support disk 107, that is, the blocking rod 112 does not block the optical fiber. At this time, the optical fiber will smoothly detach from the surface of the first optical fiber winding disk 101 and the second optical fiber winding disk 102. When winding again, the blocking rod 112 can be reset.
