Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber ring production, in particular to a glue dispensing fixture for optical fiber ring pigtails and loose sleeves. Background Art

[0002] In order to protect the pigtail of the optical fiber ring during transportation or testing, it is usually necessary to put a loose tube of about 1m on the pigtail. In order to prevent the loose tube from sliding on the pigtail and to prevent the bonded optical fiber from being peeled off by the sliding loose tube mouth, the loose tube needs to be bonded and fixed to the optical fiber ring body. During bonding, it is necessary to ensure that the head of the loose tube fits the circumference of the ring body and keep it for about two hours until the glue solidifies. Since the loose tube has a certain toughness, it is not easy to maintain the correct bonding posture with the optical fiber ring body. The adjusted bonding posture is also easy to change when the glue is not completely dry, resulting in bonding failure. As a result, when bonding the optical fiber ring body to the loose tube, the positioning of the optical fiber ring body is unstable and the glue is inconvenient.

[0003] In order to solve the problem of difficulty in maintaining positioning when the sleeve and the optical fiber ring body are bonded, a positioning fixture is needed to achieve the auxiliary positioning function of the optical fiber ring body and the loose sleeve during bonding.
