See also Fig. 1, Fig. 1 is the stereographic map according to optical fiber fusion tool of the present utility model, wherein, on worktable 1, be installed with a guide rail 2, and two slide blocks 3,3 ' slidably are installed on guide rail 2, on slide block 3,3 ' side, adhere to and be fixed with ceramic wafer (Main Ingredients and Appearance is an alundum (Al) 32,32 '.A pair of piezoelectric ceramics power output element 4,4 ' is fixed on the worktable 1, this is to piezoelectric ceramics power output element 4,4 ' output shaft 41,41 ' is connected to ceramic wafer 32 respectively, on 32 ', be used to drive slide block 3,3 ' moves on guide rail 2, for describing its type of drive in detail, please consult Fig. 2 simultaneously, Fig. 2 shows piezoelectric ceramics power output element 4,4 ' output shaft 41,41 ' movement locus is an ellipse, (the piezoelectric ceramics power output element can be buied by the market in the mode of original place rotation a great difference to be arranged with the output shaft of conventional motor, be existing commodity, therefore its structure will not be narrated), because the output shaft 41 of piezoelectric ceramics power output element, 41 ' is connected to ceramic wafer 32,32 ', therefore when output shaft 41,41 ' when making elliptical motion, to utilize friction force to push ceramic wafer 32 simultaneously, 32 ', through ceramic wafer 32,32 ' drives slide block 3,3 ' moves as linear reciprocation on guide rail 2.Optical fiber fusion tool of the present utility model more comprises a pair of suction base 5,5 ', this is provided with screw hole 51,51 ' to suction base 5,5 ' in two bottom sides, be used to cooperate the screw hole 31,31 ' on the slide block 3,3 ', can supply screw (not shown) with suction base 5,5 ' locking on slide block 3,3 ', so piezoelectric ceramics power output element 4,4 ' just can be through slide block 3,3 ' and drive suction base 5,5 ' and move along guide rail 2.
The detailed construction of suction base now is described.Because two suction bases 5,5 ' be complete symmetry, so be the masterpiece explanation only with a suction base 5 wherein.See also Fig. 3, suction base 5 is provided with on end face and is formed with a v-depression 52, be provided with two round holes 53,54 in v-depression 52 two bottom sides, this hole 53,54 is connected to air compressor machine (not shown) through air- pressure tube 61,62 respectively, can produce pull of vacuum in v-depression 52 bottoms.Must notice that hole 53,54 is connected in different air- pressure tube 61,62, therefore can control the generation pull of vacuum respectively, when for example hole 53 produced pull of vacuum, hole 54 can have pull of vacuum, also can not have pull of vacuum, is controlled by the user fully.
The operational scenario of optical fiber fusion tool of the present utility model now is described.See also Fig. 4, Fig. 4 is the combination top view according to optical fiber fusion tool of the present utility model, utilize optical fiber fusion tool of the present utility model, two optical fiber can be fixed, and between two suction bases 5,5 ', produce the point of crossing, and then make two optical fiber fusions with this point of crossing of flame heat, operation steps is as follows:
(step 1) is opened air compressor machine, and making hole 53,53 ' produce pull of vacuum hole 54,54 ' does not then have suction, then article one optical fiber is put into v-depression 52,52 ', and this optical fiber is held by hole 53,53 ' immediately.
(step 2) makes hole 54,54 ' begin to produce pull of vacuum, put into second optical fiber then, note to keep second optical fiber parallel therebetween with article one optical fiber, treat that second optical fiber is held by hole 54,54 ' after, the user strains first and second optical fiber simultaneously.
(step 3) is turned off the pull of vacuum of hole 54 ', so the right-hand part of second optical fiber is free relaxed state, the user is grabbing the right-hand part of second optical fiber, makes it intersect at article one optical fiber, and the point of crossing is between two suction bases 5,5 '.
(step 4) is opened the pull of vacuum of hole 54 ', and the user strains first and second optical fiber simultaneously then, makes the point of crossing be aligned in two suction bases 5,5 ' middle, and the result as shown in Figure 5.Wherein label 63,64 is represented above-mentioned first and second optical fiber respectively.
When first and second optical fiber 63,64 after producing the point of crossing between two suction bases 5,5 ', just can make two optical fiber fusions with this point of crossing of flame heat, detailed as following:
See also Fig. 6, an end of article one optical fiber 63 connects a light source 68, and the other end connects a device for testing light 66, and an end of second optical fiber 64 connects a device for testing light 65.Light source 68 is sent light signal, transmission in article one optical fiber 63, and before the incomplete fusion, device for testing light 66 is received 100% luminous energy.When fusion, the operator is with flame 67 heating point of crossing, have part optical signals just to enter second optical fiber 64, and can measure in device for testing light 65, to carry out fusion area more and more big along with heating, to there be more luminous energies to enter second optical fiber 64 and measure by device for testing light 65, the degree of fusion decides according to the specification demand fully, for example, and when being 50%-50% as if specification, the luminous energy of measuring when device for testing light 65,66 is all 50%, just should stop heating and fusing immediately.
Should notice that optical fiber 63,64 can be elongated sagging in when heating,, will cause the energy loss of transmission signals excessive, so in the process of whole heating and fusing, first and second optical fiber 63,64 all should remain on tension state if the optical fiber shape is crossed when curved because of sagging.Tool of the present utility model is to drive suction base 5,5 ' with piezoelectric ceramics power output element 4,4 ' to separate in the opposite direction in the process of optical fiber fusion, makes first and second optical fiber 63,64 remain at tension state, to eliminate the optical fiber sagging.
Above-described mode of operation can be changed, for example in the process of heating and fusing, 4 ' the action of piezoelectric ceramics power output element is only arranged, another piezoelectric ceramics power output element 4 then is failure to actuate, in other words suction base 5 ' moves, and that suction base 5 is maintained fixed is motionless, so also can make first and second optical fiber 63,64 remain on tension state, to eliminate the optical fiber sagging.
The utility model adopts the one reason of piezoelectric ceramics power output element to be optical fiber severe is very little at present fusing, the output displacement accuracy of existing step motor is not sufficient to accurately and effectively with its elimination, and that the output displacement accuracy of piezoelectric ceramics power output element exceeds step motor is many, be enough to accurately eliminate optical fiber sag when fusion, and then improve the qualification rate of product.
It is the output quite stable of piezoelectric ceramics power output element that the utility model adopts another reason of piezoelectric ceramics power output element, can effectively improve the shortcoming of existing step motor and shaft coupling chatter (resonance), further improves the qualification rate of product.Another advantage of the present utility model is that the whole existing tool of construction cost is low.
Though the utility model is own with preferred embodiment openly as above; right its is not in order to limit the utility model; anyly have the knack of this skill person; in not breaking away from spirit and scope of the present utility model; still can do some change and retouching, therefore protection domain of the present utility model is when being as the criterion with the claim protection domain.
