In the module, by adjusting the reversing plectrum 207 of the rotation locking adjusting unit 200, the adjustable clamping unit 100 can realize forward rotation locking (allowing reverse tension to slide in an overload manner), reverse rotation locking (allowing forward tension to slide in an overload manner) or bidirectional locking (not allowing tension to slide in an overload manner), support various winding process requirements and have good compatibility.
Specifically, as shown in fig. 6, the tension adjusting unit 400 includes a rotary cylinder 401, a push rod 402, a shaft end tapered thrust sleeve 403, a damping adjuster 404, and a sleeve 405, wherein the push rod 402 is installed in the rotary cylinder 401, the rotary cylinder 401 is installed inside and fixed to the sleeve 405, an opening is formed at one end of the sleeve 405, the push rod 402 can move telescopically along the opening, and the push rod 402 is fixedly connected to the tapered thrust sleeve; one end of the damping adjuster 404 is embedded into a cylindrical hole on the top surface of the shaft end conical thrust sleeve 403, the shaft end conical thrust sleeve 403 is embedded into a cylindrical hole on the shaft end of the friction device mounting shaft 315, the two can slide relatively, and the relative position is passively assisted and adjusted through the damping adjuster 404.
In specific implementation, the push rod 402 is fixed with the conical thrust sleeve through thread fit, the rotary cylinder 401 supplies air under the control of the upper computer, and the push rod 402 is pushed out/pulled back to drive the conical thrust sleeve to be jacked up/pulled out, so that friction torque is adjusted, and the mandrel 201 is driven to rotate and slide.
The upper computer can accurately control the output pressure of the tension adjusting unit 400 in real time, so that the shaft end conical thrust sleeve 403 pushes the thrust sheet 313 outwards along the radial direction of the torque adjusting unit 300, the torque adjusting unit 300 generates the required friction torque, the friction torque value and the optical fiber winding tension set value are in a linear relation, when the optical fiber winding tension on the sensitization body is overloaded, if the rotary motion in the direction is not locked, the adjustable clamping unit 100 and the mandrel 201 will rotate and slide relative to the torque adjusting unit 300 until the tension value is smaller than the corresponding friction torque value again.
Specifically, the rotary cylinder 401 supplies air through a pneumatic slip ring or other methods, and controls air pressure and flow through a high-precision proportional valve to achieve precise pressure control. When the sliding tension control device is actually used, a corresponding control algorithm is realized in control software through a calculation formula among a maximum tension value, friction torque and cylinder thrust, so that the accurate control of the maximum sliding tension value is realized. In some embodiments, the tension adjusting unit 400 may use a cylinder and proportional valve assembly, a torque motor plus a small lead screw, etc. to provide the required pressure to the first friction plate 309.
In the module, the tension adjusting unit 400 and the torque adjusting unit 300 are designed to be coupled, and the torque is adjusted by using the sliding friction effect, so that the optical fiber winding tension on the sensitization body is adjusted. Particularly, when the tension of the optical fiber is overloaded, the optical fiber pulls the clamped sensitization body to slide relatively along with the adjustable clamping unit 100 and the torque adjusting unit 300, the damping is increased by using the action of friction, the winding tension can be quickly adjusted to return to a set value, the optical fiber is effectively prevented from being broken, and the winding quality and reliability of the optical fiber are improved.
As shown in fig. 7, the using process of the optical fiber winding module includes: determining an optical fiber winding scheme, judging the shape of the sensitization body, replacing a clamping piece suite corresponding to the shape of the sensitization body, clamping and fixing the sensitization body or an optical fiber disc (wherein a hollow tubular sensitization body corresponds to a tubular sensitization body clamping piece assembly 130, and a solid cylindrical sensitization body corresponds to a cylindrical sensitization body clamping piece suite), setting the locking direction of a rotary locking adjusting unit 200 through a rotary locking piece 206 and a reversing shifting piece 207, locking, setting the winding tension of the optical fiber through an upper computer, and controlling the tension adjusting unit 400 to output corresponding pressure and maintain the force through the upper computer, namely realizing the constant-tension winding of the optical fiber; when the optical fiber tension is overloaded, the adjustable clamping unit 100 drives the sensitization body or the optical fiber disk to slide rapidly, so that the overloaded tension on the optical fiber is reduced rapidly, the overload protection of the optical fiber tension is realized, and then the optical fiber tension enters a constant tension winding mode again, and finally the high-quality winding work of the sensitization unit is completed.
