Embodiment 1

[0067] refer to figure 1 and figure 2 , an automatic coupling device for a coupling dispensing system provided in this embodiment, the automatic coupling device is used to couple the device to be coupled 1 and the optical fiber 2, the automatic coupling device includes: a clamping mechanism 3 and an adjusting mechanism 4, the The clamping mechanism 3 is arranged on the adjusting mechanism 4 .

[0068] In this embodiment, the clamping mechanism 3 includes a sliding platform 31 and an elastic member 32 , one end of the elastic member 32 is connected to the sliding platform 31 . Wherein, the elastic member 32 can be a spring, and the elastic force of the spring should not be too large, otherwise it will cause edge collapse of the device 1 to be coupled. In an optional embodiment, the maximum load of the spring is 4N, and the spring constant is greater than 1.0N / mm. In the actual design process, the friction force and other factors when the slide table 31 slides can be consider...

Embodiment 2

[0109] Different from Embodiment 1, the automatic coupling device coupled with the dispensing system provided in this embodiment has another optional solution, which detects the compression state of the elastic member 32 so that the adjustment mechanism 4 can adjust the posture of the clamping mechanism 3 . Such as Figure 15 As shown, the clamping mechanism 3 also includes a pressure sensor 342, the pressure sensor 342 is arranged on the base 33, and the other end of the elastic member 32 is connected to the pressure sensor 342; the pressure sensor 342 It is used to detect changes in the elastic force of the elastic member 32 to trigger the adjustment mechanism 4 to adjust the posture of the clamping mechanism 3 .

[0110] In this embodiment, the pressure sensor 342 is used to detect the change of the elastic force of the elastic member 32 to determine the compression state of the elastic member 32 and determine the sliding table 31 (such as Figure 15 Shown, the distance be...

Embodiment 3

[0116] An embodiment of the present invention provides a coupling dispensing method, which is applicable to the coupling dispensing system in the above-mentioned embodiment 1 or embodiment 2.

[0117] Such as Figure 17 As shown, the coupling dispensing method of the present embodiment includes the following steps:

[0118] Step S10: Clamp the optical fiber on the clamping mechanism, and fix the device to be coupled on the fixed platform.

[0119] Step S20: adjusting the posture of the clamping mechanism through an adjusting mechanism, and detecting the compression state of the elastic member, so that the end face of the optical fiber is parallel to the end face of the device to be coupled.

[0120] Step S30: Dispensing glue in the side direction on the coupling surface between the optical fiber and the device to be coupled.

[0121] In a specific application scenario, the sensor acquires the change of the compression state of the elastic member to monitor the contact state ...

Abstract

The invention discloses a coupling dispensing system and a coupling dispensing method. An automatic coupling device of the coupling dispensing system is used for coupling a device to be coupled and anoptical fiber and comprises an adjusting mechanism and a clamping mechanism, wherein the clamping mechanism is arranged on the adjusting mechanism and comprises a sliding table and an elastic piece,one end of the elastic piece is connected with the sliding table, and the clamping mechanism is used for clamping the optical fiber; and the adjusting mechanism is used for adjusting the posture of the clamping mechanism so that the end face of the optical fiber is parallel to the end face of the device to be coupled. The automatic coupling device can enable the end face of the optical fiber to beparallel to the end face of a device to be coupled, and the consistency is good. The dispensing device of the coupling dispensing system is used for dispensing in the lateral direction on the end faces of the optical fiber and the device to be coupled, so that no glue is arranged on the light passing surfaces of the optical fiber and the device to be coupled, heat energy generated when light passes through the coupling glue is reduced, and the bearing power of the device can be improved.

Description

technical field [0001] The invention belongs to the technical field of optical device manufacturing, and more specifically relates to a coupling dispensing system and a coupling dispensing method. Background technique [0002] In the field of optical communication, planar lightwave circuit (PLC for short) technology is a technology based on a PLC chip for splitting optical power or splitting wavelength. [0003] On the one hand, it is more difficult to couple the PLC chip and the fiber array FA (FiberArray, abbreviated as FA). , return loss) has a decisive influence. At the same time, in order to reduce the light reflected by the PLC chip coupling end face and increase the return loss, the PLC chip coupling end face is generally ground to a certain inclination angle, and the FA coupling end face also needs to be ground to a corresponding inclination angle. Therefore, it is very difficult to form two parallel planes between the coupling end surface of the PLC chip and the c...
