Description

Optical fiber splicer automatic heating furnace
Technical field
The present invention relates to a kind of optical fiber splicer automatic heating furnaces, for protecting after the completion of fused fiber splice to optical fiber pyrocondensation Casing is heated automatically, belongs to field of photoelectric technology.
Background technique
With the continuous development of mechanics of communication, optical-fibre communications has carried more and more missions, the type of optical fiber splicer Also just it is more and more, to it is intelligentized require be also it is higher and higher, optical fiber can be realized three-dimensional automatically to the basis of core welding On, after the completion of fused fiber splice for optical fiber pyrocondensation protection sleeve pipe efficiency be also it is higher and higher, both required heating time will be as far as possible It is short, while heating operation also being required to realize intelligence as far as possible, realize automatic heating.
And optical fiber splicer, as construction equipment, most cases are to work outdoors by the energy of cells, are led to The efficiency that the mode heated automatically improves pyrocondensation protection sleeve pipe is crossed, and welding speed can be improved, and each welding energy consumption can be reduced, The welding quantity once to charge is improved, also has having very great significance for promoting product competitiveness.
There are still some shortcomings in use for existing automatic heating furnace, and the success rate heated automatically after placing such as optical fiber is not Be it is special it is high, for the clamping of different-diameter optical fiber, there is also certain compatibility issue, (bare fibre is not clamping, covered wire cable lid It is not tight etc.), for these technical problems, applicant is designed optical fiber splicer of the invention and is heated automatically by research of technique Furnace.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the present invention provides a kind of the automatic of optical fiber splicer Heating furnace.
Technical solution: in order to solve the above technical problems, optical fiber splicer automatic heating furnace provided by the invention, including heating Furnace, signalling means, control system and shell, the shell are used for grip optical fiber, it is characterised in that: the signalling means includes the first letter Number device and second signal device, for first signalling means for obtaining enclosure closed signal, the second signal device is outer for obtaining Shell grip optical fiber signal, starting heating when the control system obtains enclosure closed signal and shell grip optical fiber signal at the same time Furnace.
Specifically, the shell includes cover board and pedestal, and the cover board is respectively equipped with the end of pedestal with hinge , there are three hinge holes of perforation, the pin runs through hinge hole, and the pin is located at three hinge holes on the hinge seat Interior three sections have different diameters.
Specifically, first signalling means includes trough type photoelectric sensor and the first movable block being mounted in sliding seat, First movable block has the top of ejection, the bottom of connecting spring and side tab;When closing cover board, cover board is connect Top is touched and depressed, lug is enabled to enter in the groove of trough type photoelectric sensor.
Specifically, the second signal device includes trough type photoelectric sensor and the second movable block being mounted in sliding seat, Second movable block is mounted in sliding seat, has the top of ejection, the bottom of connecting spring and side tab;When putting When entering optical fiber, cover board contacts and depresses top, and lug is enabled to enter in the groove of trough type photoelectric sensor.
Specifically, there is the through slot for placing optical fiber in the shell, be equipped with flexible clamping device close to through slot both ends, The middle part of the through slot is equipped with heating tank;The flexible clamping device includes spring bearer plate, cover spring and rubber pad.
