Description
[ technical field ]
The invention belongs to optical fiber ring curing pretreatment equipment in the field of optical fiber sensing, and particularly relates to equipment for improving the yield and efficiency of optical fiber ring curing.
[ background art ]
The optical fiber ring is a core device of the optical fiber gyroscope, and the quality of the manufactured optical fiber ring plays a decisive role in the performance of the optical fiber gyroscope. The optical fiber ring is manufactured by regularly winding sensitive optical fibers by adopting sensitive optical fibers, a ring winding adhesive and a specific ring winding process. The winding process of the optical fiber ring generally adopts methods such as tape winding or later-stage glue filling, so that the ring-winding glue permeates into the optical fiber ring, and the sensitive optical fiber is fully bonded, so as to ensure the structural strength of the optical fiber ring.
However, in any method, it is difficult to ensure the uniform distribution of the ring-surrounding glue in the optical fiber ring, and therefore, a homogenizing operation of the optical fiber ring-surrounding glue is required to be added just before the optical fiber ring is wound and uncured, that is, the optical fiber ring is rotated in a specific manner in an uncured state, so that the ring-surrounding glue is continuously flowed in the ring by rotation, and the uniformity of the ring-surrounding glue in the ring is improved.
The optical fiber ring glue surrounding homogenizing operation is realized by optical fiber ring curing pretreatment equipment at present. The basic principle is that a rotating shaft is driven to rotate by a rotating motor, and the optical fiber ring winding clamp is fixed on the rotating shaft, so that synchronous rotation can be realized. The existing optical fiber ring curing pretreatment equipment has two problems: firstly, the motor is directly connected with one end of the rotating shaft through the coupler, and the optical fiber ring is arranged at the other end. The connection mode has higher requirement on the coaxiality of the motor shaft and the rotating shaft. In the use process of the equipment, the phenomenon of radial runout of the rotating shaft in the process of driving the rotating shaft to rotate by the motor due to too low coaxiality of the motor shaft and the rotating shaft often occurs, so that the optical fiber rings are not stably rotated, the glue homogenizing effect is poor, and only one optical fiber ring can be generally placed at a time; secondly, most of the fiber ring rotation modes of the existing fiber ring curing pretreatment equipment are constant rotation speed modes, the rotation speed and the time are not adjustable, and the viscosity of the surrounding adhesive in the fiber ring changes nonlinearly along with the time in the actual situation, so that if the rotation modes of the fiber ring can be set according to the change rule of the viscosity of the surrounding adhesive along with the time, the homogenization effect of the fiber ring can be more favorably realized, for example, the rotation speed of the fiber ring is gradually reduced along with the increase of the viscosity of the surrounding adhesive.
[ summary of the invention ]
The invention aims to perform glue homogenizing operation on an optical fiber ring which is just wound and is not subjected to curing operation, and solves the problem that the ring yield is influenced because the ring internal surrounding glue is not uniformly distributed after the optical fiber ring is wound.
The implementation mode of the invention is as follows:
the equipment comprises a touch screen, a control module, a motor driver, a motor, a synchronizing wheel, a synchronous belt, a rack, a tooling fixture, a rotating shaft, an optical fiber ring, a bearing seat, a shell and a power supply module. The touch screen is used for inputting a motor rotation mode and operation parameters, the control module generates an actual rotation curve according to the rotation mode and the operation parameters and controls the motor to move according to the curve, the rotation mode comprises but is not limited to static, constant speed, variable speed and a combination of static, constant speed and variable speed, and the operation parameters comprise but is not limited to rotation speed, rotation angle and rotation duration.
The control module is respectively connected with the power supply module and the motor power mechanism, and the synchronous belt transmission mechanism is respectively connected with the motor power mechanism and the optical fiber ring rotating shaft.
Synchronous belt drive mechanism rotates the motor and transmits the middle part of optic fibre ring axis of rotation for the both sides of optic fibre ring axis of rotation all can be used for placing the optic fibre ring.
The rotation mode at least comprises one of the following rotation modes: presetting t1，t2，t 33 time values and v1，v 22 rotation speed values, the relationship between the operation time t and the rotation speed v of the rotation shaft of the optical fiber ring can be determined by the following formula:
when t is more than or equal to 0 and less than t1When the temperature of the water is higher than the set temperature,
when t is1≤t＜t2When v is equal to v1；

when t is3When t is less than or equal to v2；
Wherein A is more than or equal to 10, the time unit is minutes, and the rotating speed unit is revolutions per minute.
The invention has four beneficial effects: firstly, through increasing hold-in range slewing mechanism, eliminated through shaft coupling motor and pivot because of assembly error lead to the pivot to do the problem of radial runout when rotatory, improved the stationarity of optic fibre ring when rotatory. And the rotating shaft is installed and drives the two optical fiber rings to rotate simultaneously in a mode that the two sides of the rotating shaft extend out, so that the instability of rotation of the optical fiber rings generated by bearing the two optical fiber rings in a single-side extending mode is reduced. And thirdly, a programmable control function of an optical fiber ring rotation mode is added, the rotation mode of the optical fiber ring can be preset according to the adhesive property change characteristic of the winding ring, the problem that the rotation speed and the rotation time cannot be adjusted in the conventional optical fiber ring curing pretreatment is solved, and the adhesive uniformity in the optical fiber ring curing pretreatment is improved. Fourthly, a nonlinear empirical formula of the rotating speed and the rotating time is given according to the general characteristic of the adhesive property change of the existing winding ring.
