Although describe in the above embodiments the end face of the multifiber be pierced by completely multi-fiber ferrule it is rear to
The case where applying adhesive in multi-fiber ferrule, still, the present disclosure is not limited thereto.Adhesive applicator can also be applied at other moment
Add adhesive, such as is inserted into multi-fiber ferrule and its front end face when multifiber is not inserted into multi-fiber ferrule, in multifiber
When having passed through window and/or when detecting the overhang is predetermined value.In this way, can make multifiber more fully by
Apply adhesive.
Although describing in above embodiment is pierced by the end face of the multifiber completely in described wear
The case where multi-fiber ferrule, but it may occur to persons skilled in the art that, it is worn in fine step described, in the model for not departing from the disclosure
In the case where enclosing, the end face of the multifiber can not also be made to be pierced by multi-fiber ferrule completely, and only be inserted partially into it
Multi-fiber ferrule.In the case, in the overhang rate-determining steps, when determine detected overhang be less than predetermined value or
When the end face of the multifiber is not prominent, so that multifiber is moved along direction of insertion.
Preferably, in the optical fiber fixing step, make described adhesive quickly solid when the overhang is predetermined value
Change.As previously described, rapid curing can be using at least one of ultraviolet curing, infrared ray cured heat cure etc.
Rapid curing mode.By rapid curing, once the overhang detected is equal to predetermined value, just rapidly multifiber is fixed
In multi-fiber ferrule, ensure that the overhang is accurately met the requirements.
Preferably, in the overhang detecting step, vision sensing equipment sensing includes the described of the multifiber
The sensing image of end face.Preferably, the benchmark image stored in the sensing image and memory is compared by processor, root
The overhang is obtained according to comparison result.Preferably, processor can also be by calling the image procossing journey stored in memory
Sensing image described in ordered pair is handled, to obtain the overhang.
The multi-fiber connector that present disclosure also relates to be fabricated by the above-mentioned manufacture method.
Although the disclosure is described using multi-fiber connector as example, it may occur to persons skilled in the art that,
The manufacturing method and system of the disclosure can also be equally applicable to the manufacture of single fiber-optic connector.
Although it have been described that the example embodiment of the disclosure, it will be understood by those skilled in the art that at this
A variety of variations can be carried out in the case where not departing from spirit and scope of the present disclosure in matter to the example embodiment of the disclosure and are changed
Become.Therefore, all changes and change are all contained in the protection scope of the disclosure defined by claim.The disclosure is by adding
Claim limit, and the equivalent of these claims is also included.
