Description

Casing eccentricity measuring device

technical field

The present invention relates to a sleeve eccentricity measurement device for measuring the eccentricity of an optical fiber insertion hole formed in the sleeve and the eccentricity of an optical fiber core mounted on the sleeve.

Background technique

The ferrule is installed on the front end of the optical fiber as a component of the connector of the optical fiber to protect and center the end. It has a tubular shape with an insertion hole for the optical fiber in the center or a flanged type with a flange in the center or on one side of the tube. wait.

For example, a ferrule for a single-mode optical fiber with a cladding diameter of 125 μm has an outer diameter of about 1.5 to 2.5 mm, and an optical fiber insertion hole with an inner diameter of about 126 μm.

When using this ferrule for optical connection, after polishing the end face of the ferrule installed at the front end of the fiber for each optical fiber, insert the ferrule from both sides of the ferrule corresponding to the outer diameter of the ferrule, and align the end faces of the optical fibers with each other in the middle. Just right.

In this case, even if the outer diameter and the inner diameter of the fiber insertion hole are formed with high precision, if the center of the insertion hole and the outer diameter of the ferrule is formed eccentrically, the optical loss at the connecting portion will increase.

For example, in the case of a single-mode optical fiber with a core diameter of 10 μm, when two butted ferrules are eccentric to each other by 1 μm, the light transmission efficiency will drop to about 50%.

For this reason, the manufacturer inspects all the ferrules manufactured, and classifies them according to the measured eccentricity, from single-mode optical fibers that require high precision, to multi-mode optical fibers that require less precision, to unsuitable as ferrules. Classify the non-conforming products.

FIG. 4 is an explanatory diagram showing such a conventional bushing eccentricity measuring device.

The casing eccentricity measurement device 51 forms a V-shaped groove 4 for placing the casing W along the substantially horizontal photographic optical axis Z from the light source 2 to the camera 3, and makes the rotating roller 55 contact the casing W placed in the V-shaped groove 4. And make it rotate, at the same time, the end face is photographed by the above-mentioned camera 3, and the eccentricity of the optical fiber core installed in the insertion hole 6 and the eccentricity of the optical fiber core installed in the ferrule can be measured.

The rotating roller 55 is installed on the front end of the rotating arm 57 driven by the cylinder 56. When the sleeve W is placed in the V-shaped groove 4, the piston rod 58 of the cylinder 56 is extended, and the arm 57 rotates downward. The rotating roller 55 contacts the Casing W.

Here, if the light source 2 is turned on to display only the fiber insertion hole 6 and the end surface is enlarged and photographed, the light from the light source 2 makes the part of the fiber insertion hole 6 appear white and the other parts appear black. Therefore, by performing Image analysis detected the center coordinates C (c, y) of the white optical fiber insertion hole 6 .

In this state, start the rotating roller 55 to rotate the casing W at a predetermined speed, and when the center coordinate C (x, y) is detected at a predetermined time interval, if the center coordinate C (x, y) does not change, then It can be judged that the fiber insertion hole 6 is not eccentric. If the center coordinate C (x, y) changes, it can be judged that the fiber insertion hole 6 is eccentric. At this time, the center coordinate C (x, y) changes by 1 /2 is equivalent to the amount of eccentricity.

In addition, the circularity of the optical fiber insertion hole 6 can also be measured by measuring the diameter in the horizontal direction or the vertical direction of the optical fiber insertion hole 6 while rotating the ferrule W.

However, such a bushing eccentricity measurement device 51 takes a long time to inspect each bushing and has a problem of low processing efficiency.

The reason for this is that after placing the cannula W in the V-shaped groove 4, it is automated until the measurement is completed, but the action of placing the cannula W in the V-shaped groove 4 and taking it out after the measurement is completed is performed manually by the operator. , cannot be automated.

If a manipulator or the like can be used to automate the placement or recovery of the sleeve W from directly above the V-shaped groove 4, not only can the single measurement time be shortened, but also a 24-hour full operation can be performed, so the daily processing efficiency can be further improved.

However, since the rotating arm 57 supporting the rotating roller 55 is provided immediately above the V-groove 4, this becomes an obstacle and the manipulator cannot be installed.

In addition, since the sleeve W is placed or retrieved into the V-shaped groove 4 by manual work, it is necessary to ensure a large space above the V-shaped groove 4 to allow the hands to freely enter and exit during the period when the rotating roller 55 is not in contact. Here, the swivel angle of the swivel arm 57 supporting the swivel roller 55 is set to be large, and retracted to a position away from the V-shaped groove 4 .

Therefore, the moving distance from the retracted position of the rotating roller 55 to the working position contacting the sheath W is long, and it takes a long time to move the rotating arm 57 forward and backward, resulting in a problem that a single measurement time becomes longer.

Contents of the invention

The technical subject of the present invention is to shorten the advance and retreat time of the rotating roller by completely retracting the rotating roller from the upper position of the V-shaped groove with a shorter moving distance. The casing recovery operation can be carried out quickly and reliably, improving the processing efficiency.

In order to solve this problem, the tube eccentricity measurement device according to the first aspect of the present invention sets the tube in a V-shaped groove formed along the substantially horizontal imaging optical axis, and makes the rotating roller touch the tube to rotate it. Take a photo at the end to measure the eccentricity of the optical fiber insertion hole or the eccentricity of the optical fiber core installed in the sleeve; it is characterized in that: the sleeve rotation mechanism that rotates the sleeve placed in the above-mentioned V-shaped groove has a 2-axis slide table and a table driving mechanism; the 2-axis slide table is provided with the above-mentioned rotating rollers on the front end side, and is arranged to be able to advance and retreat in the front-rear direction and the up-down direction of the above-mentioned photographing optical axis; the table driving mechanism retracts the above-mentioned rotating rollers from the rear of the photographing optical axis The position advances to just above the V-shaped groove, and descends from the entry and exit position to the working position in contact with the casing.

According to the first aspect of the present invention, since the rotating rollers are provided on the two-axis slide table that moves in the front-rear direction and the vertical direction, the rotating rollers can be moved upward from the working position where the bushing is in contact, and the rotating rollers can be retracted away from the bushing. To the rear, the rotating roller can be retracted completely from directly above the V-shaped groove with a small moving distance of about 1 to 2 cm in the vertical direction and the front-rear direction.

Therefore, the rotation of the rollers does not become an obstacle in the case of placing the casing by manual work or in the case of automatically placing the casing by using a manipulator or the like, and full automation can be realized.

In addition, since the moving distance in the up-down direction and the front-back direction can be shortened, the time for advancing and retreating the rotating roller can be shortened, and the time required for measurement can be shortened in both manual work and automation to place the cannula, and the processing efficiency can be improved.

In this case, if the cam mechanism according to the fourth aspect of the present invention is used as the table driving mechanism, the rotating rollers can be sequentially moved in two directions of front-down or up-back by a single operation.

In addition, in the second aspect of the present invention, the cannula conveying mechanism for recovering the measured cannula from the V-shaped groove and placing other cannula has the function of making the suction picker for absorbing the cannula along with the photographing side through the above-mentioned V-shaped groove. A manipulator that reciprocates in a horizontal direction that is approximately perpendicular to the optical axis, a setter that houses the tubes that will measure the eccentricity in advance, and two or more tube recycling boxes that collect the measured tubes that have fallen from the picker in order along the above The trajectory configuration of the picker.

According to the second aspect of the present invention, the bushing placed on the installer is vacuum-adsorbed to the pick-up, transported by the manipulator to the top of the V-shaped groove, and released from the pick-up on the V-shaped groove, thereby ending the V-shaped groove. placed.

When the measurement is completed, the sleeve placed in the V-shaped groove is vacuum-adsorbed to the picker, transported to a predetermined recovery box corresponding to the measurement result, and released from the picker on the recovery box, thereby recovering by grade.

As in the fifth aspect of the present invention, the installer moves the trays arranged in a matrix with the sleeves on the pallet table so that the sleeves are located directly under the picker, and the picker can always be vacuum-adsorbed at a certain place. Therefore, Even if the movement of the robot arm is simple, the bushings can be placed in the V-shaped grooves one by one.

In addition, as in the sixth aspect of the present invention, if the manipulator is provided with a pick-up for placing the bushing to be measured for the amount of eccentricity from the above-mentioned mounter to the V-shaped groove, and from the above-mentioned V-shaped groove, the bushing after the measurement is completed The measurement time can be shortened by using two pickers for collecting tubes that are transported to the tube recycling box.

In this case, the bushing of the mounter is vacuum-adsorbed to the picker for placement, and the manipulator is moved to the V-shaped groove.

Then, the sleeve tube set in the V-shaped groove after the measurement is completed is vacuum-adsorbed to the recovery picker, and the sleeve tube of the set picker is set in the V-shaped groove.

On the way back to the mounter, the manipulator may also release vacuum adsorption to the bushing of the picker for recovery on a predetermined recovery box corresponding to the measurement result.

In this way, by making the manipulator perform one reciprocation, the casing can be placed in the V-shaped groove and the casing can be recovered from the V-shaped groove simultaneously.

Detailed ways

Embodiments of the present invention will be specifically described below with reference to the drawings.

FIG. 1 is a schematic configuration diagram showing the main parts of a bushing eccentricity measuring device according to the present invention, and FIG. 2 is a diagram showing its overall configuration.

Fig. 1 and Fig. 2 show the bushing eccentricity measurement device 1 of the present invention, form the V-shaped groove 4 that places bushing W along the substantially horizontal photographing optical axis Z from light source 2 to video camera 3, make rotating roller 5 contact The ferrule W placed there is rotated, and at the same time, the camera 3 can take pictures of its end face to measure the eccentricity of the optical fiber insertion hole 6 and the eccentricity of the optical fiber core installed in the ferrule.

The casing eccentricity measurement device 1 has a casing rotation mechanism 7 and a casing delivery mechanism 8. The casing rotation mechanism 7 rotates the casing W placed in the V-shaped groove 4, and the casing transportation mechanism 8 moves from the V-shaped groove 4. The casing W that has been measured is recovered, and other casings W to be measured later are placed.

The casing turning mechanism 7 has a biaxial sliding table 9, a table driving mechanism 10, and a motor 11. The sliding table 9 is provided with a rotating roller 5 on the front end side, and is arranged so as to advance and retreat in the front-back direction and the up-down direction of the above-mentioned imaging optical axis Z. ; The table drive mechanism 10 drives the sliding table 9 up and down forward and backward; the motor 11 makes the rotating roller 5 rotate.

The slide table 9 has a Z stage 9Z that slides back and forth on the fixed base 12 along the imaging optical axis Z direction, and a Y stage 9Y that is mounted on the Z stage 9Z so that it can be raised and lowered. The Y stage 9Y supports the rotating roller 5 and its driving motor 11 .

The Z table 9Z is elastically applied forward by the spring 13Z, and at the same time, it is stopped at the front end by a stopper (not shown) formed on the fixed base 12. The Y table 9Y is elastically applied upward by the spring 13Y, and at the same time , is stopped at an upper end position and a lower end position by a stopper (not shown) provided on the Z stage 9Z.

In addition, the stage driving mechanism 10 is equipped with a Z-direction moving cam (first cam) 15Z that moves the Z stage 9Z forward and backward along the photographing optical axis Z and a Y stage that moves the Y stage relative to the photographing optical axis Z on the rotary shaft 17 of one motor 16 . 9Y is a Y-direction moving cam (second cam) 15Y that moves up and down.

The first cam 15Z engages with the cam groove 18Z formed on the Z table 9Z, and when the motor 16 is rotated to 0-180° in the positive direction, for example, the rotating roller 5 is advanced to the V-shaped groove in the first half of the rotation of 0-120°. 4, when the Z table 9Z contacts a stopper (not shown) formed on the fixed base 12 (120°), the first cam 15Z is suspended.

The second cam 15Y comes into contact with the driven plate 18Y formed on the Y table 9Y. In the first half of the rotation of 0 to 120°, the Y table 9Y sets the cam displacement to 0 without moving up and down. In the second half of the rotation of 120 to 180°, The Y stage 9Y is lowered, and stops when the Y stage 9Y comes into contact with a lower limit stopper (not shown) formed on the Z stage 9Z.

In this way, the Z table 9Z is located at the rear end position, and at the same time, the Y table 9Y is located at the upper end. In this state, when the cams 15Z and 15Y are rotated synchronously in the positive direction by the motor 16, the above-mentioned rotating rollers will rotate in the first half of their rotation. 5 Advance about 2 cm from the back retreat position P ₀ of the photographing optical axis Z to P ₁ directly above the V-shaped groove 4, and in the second half of its rotation, the above-mentioned rotating roller 5 descends about 1 cm until it touches the working position P ₂ of the sleeve W , the rotating roller moves from the retracted position P ₀ to the working position P ₂ by a single action.

In addition, when turning in the opposite direction synchronously, it moves from the working position P ₂ to the retracted position P ₀ by a single operation.

The rotating shaft of the rotating roller 5 is arranged at a slight inclination relative to the V-shaped groove 4. When the rotating roller 5 rotates the sleeve W, the friction of the rotating roller 5 exerts an elastic force on the sleeve W toward the camera 3 side.

In this way, the front end surface of the sleeve W always touches the sleeve stopper 19 provided between the V-groove 4 and the camera 3, and the camera 3 focuses on the end surface of the sleeve W in this state.

A through hole 19 a is formed coaxially with the imaging optical axis Z in the stopper member 19 . The ferrule-side opening of the through hole 19 a is formed to be thicker than the outer diameter of the optical fiber insertion hole 6 , while the camera-side opening is formed to have an enlarged diameter.

In this way, the disturbing light passing through the outside of the ferrule W can be reliably blocked, and at the same time, the light diffused from the end surface of the ferrule W through the fiber insertion hole 6 is not blocked to enter the camera 3 .

At the lower end of the manipulator 20, the sleeve conveying mechanism 8 is provided with a picker 21A for placing the sleeve W in the V-shaped groove 4 and a picker 21A for placing the sleeve W in the V-shaped groove 4 and recovering the sleeve W after the measurement is completed from the above-mentioned V-shaped groove 4. Use pick-up 21B.

The manipulator 20 is arranged so as to be able to walk along the guide rail 22 so that the pickers 21A and 21B pass right above the V-shaped groove 4 and reciprocate in the horizontal left-right direction substantially perpendicular to the imaging optical axis Z.

An air circuit (not shown) for independently performing air suction and stop is formed in each of the pickups 21A and 21B.

In addition, installer 23 and eight bushing recovery boxes 24A to 24H are set along pickers 21A and 21B, and this installer 23 pre-places the bushing W to be measured for eccentricity; these eight bushing recovery boxes 24A to 24H will be The measured bushings W dropped by the recovery picker 21B are collected in six grades, for example, from high-quality products to defective products.

The installer 23 is provided with a stocker 26A for supply, a stocker 26B for recovery, and a pallet transfer device 27; the stocker 26A for supply stacks the trays 25 that arrange the bushings W... in a matrix; the stacker for recovery The tray 25 that has become empty is stacked by the device 26B; the tray transfer device 27 moves the uppermost tray 25 of the supply stacker 26A, and positions each sleeve W directly below the suction position of the picker 21A for placement, and at the same time, The empty tray 25 is sent out to the collection stocker 26B.

Each of the supply stockers 26A and 26B is provided with a height adjusting device (not shown) that always keeps the height of the uppermost tray 25 constant regardless of the number of stacked trays 25 .

In addition, a concave portion (not shown) for placing the sleeves W in the same direction is formed on the tray 25, and its depth is formed deeper than the outer diameter of the sleeve W. The sleeve W is formed protrudingly.

In addition, in this example, the light source 29 and the camera 30 of the photographing optical system for outer diameter measurement that photograph the horizontal upper end surface of the sleeve W placed in the V-shaped groove 4 are arranged along the horizontal direction perpendicular to the photographing optical axis Z. .

The above is an example of the configuration of the present invention, and its operation will be described below.

When the measurement is started, first, the rotating roller 5 of the casing turning mechanism 7 is made to wait at the retracted position _P0 , and one or more trays 25 on which the casing tubes W... are placed are stacked on the supply stocker 26A.

When the switch (not shown in the figure) is turned on, the uppermost pallet 25 of the supply stocker 26A is moved by the pallet transfer device 27, and the initial sleeve W is positioned at the suction position _Q1 of the placement picker 21A. Directly below.

Next, the picker 21A for placement is positioned directly above the suction position by the manipulator 20 and extended, and its front end is lowered to a position in contact with the sleeve W, and vacuum suction is performed on the sleeve W, and then the picker for placement is moved 21A contracts to move the manipulator 20 .

After positioning the picker 21A for placement directly above the V-shaped groove 4, the picker 21A for placement is extended again, and the sleeve W is lowered to a position in contact with the V-shaped groove 4. The atmosphere is released, and the sleeve W is released on the V-groove 4 .

Then, when the rotary shaft 17 is rotated by the motor 16 by a predetermined angle in the positive direction, the Z table 9Z is moved by the cam 15Z in the first half of its rotation, and the rotating roller 5 advances from the retracted position _P0 to just above the V-shaped groove 4. P ₁ , and then, in the second half of its rotation, the cam 15Y pushes the Y table 9Y downward, and descends to the working position P ₂ where the rotating roller 5 contacts the casing W.

At this time, the advance amount from the retracted position _P0 to the directly above _P1 of the V-shaped groove 4 is only 2 cm, and the descending amount to the working position _P2 contacting the sleeve pipe W is only 1 cm. The two cams 15Z, 15Y are synchronously rotated by a single operation of a predetermined angle to move the rotating roller 5 in two directions, so the moving time is extremely short.

Here, when the motor 11 of the casing rotating mechanism 7 is started to rotate the rotating roller 5, the casing W in contact with it rotates in the V-shaped groove 4, and at the same time, the rotating shaft of the rotating roller 5 is slightly opposite to the V-shaped groove 4. It is installed obliquely, so the front end surface of the sleeve W is pushed against the sleeve stopper member 19 by the friction of the rotating roller 5 .

At this time, since the camera 3 focuses on the front end surface of the ferrule W, the light passing through the fiber insertion hole 6 makes this part appear white and the other parts appear black, so the fiber insertion hole can be measured by performing image analysis. 6, the camera 30 measures the deviation of the external dimensions.

When the cannula W is rotated once to complete the measurement, the rotating roller 5 is retracted to the retracted position P ₀ .

In this case, since the moving distance of the rotating roller 5 is short, the moving time can be extremely short, the measurement time per measurement can be shortened, and the processing efficiency can be improved.

When recovering the cannula after the measurement is completed, in the same manner as above, the cannula W placed subsequently is adsorbed to the picker 21A for placement, and the picker 21B for recovery is positioned directly above the V-shaped groove and stretched. Vacuum adsorption is performed at the moment of contact with the sleeve W.

After the ferrule W adsorbed by the picker 21A for setting is placed in the V-shaped groove 4, the vacuum adsorbed by the picker 21B for recovery is released immediately above the ferrule recovery boxes 24A to 24H of the level corresponding to the measurement results. The casing W can be automatically graded and recycled.

In this way, according to this example, if the tray 25 on which the bushing W to be measured is placed is stacked on the supply stocker 26A of the installer 23, then each bushing W is transported from the tray 25 to the V-shaped groove 4, and After measuring the amount of eccentricity of the optical fiber insertion hole 6, it can be carried out fully automatically until classification according to the measurement result is performed.

Furthermore, since the moving distance of the rotating roller 5 is short, the rotating roller 5 can be moved in two directions by a single operation of rotating the motor 16 by a predetermined angle, so the moving time can be extremely short.

Therefore, when the sleeve pipe W is automatically placed in the V-shaped groove 4 to measure the eccentricity by the sleeve conveying mechanism 8, and when the sleeve W is manually placed in the V-shaped groove 4 to measure the eccentricity, both Since the moving time of the rotating roller 5 is shortened, the processing efficiency is improved.

In the above description, as the bushing eccentricity measurement device 1, the case where the bushing W is automatically placed in the V-shaped groove 4 by the bushing conveying mechanism 8 is described, but the bushing turning mechanism 7 is also suitable for use without the bushing conveying mechanism. 8 casing eccentricity measuring device.

In addition, not only the eccentricity of the fiber insertion hole 6 is measured, but also the fiber core can be measured by manually installing the sleeve W attached to the front end of the fiber into the V-groove 4 and connecting the other end side of the fiber to the light source. The eccentricity of the part.

As explained above, according to the present invention, the rotating roller can be completely retracted from the upper position of the V-shaped groove by a short moving distance, so the sleeve tube is automatically placed in the V-shaped groove by the manipulator and placed in the V-shaped groove by manual work. In the case of grooves, the advance and retreat time can be shortened, and the measurement time of each casing can be shortened, the processing efficiency can be improved, and a very good effect can be produced.

In addition, if a tube delivery mechanism using a robot is installed, the tube placed on the mounter can be automatically transported to the V-shaped groove. When the measurement of the eccentricity is completed, it can be placed in the V-shaped groove according to the measurement result. The bushings are collected into the collection bins separated by ranks, so the setting/recovery of the bushings can be carried out quickly and reliably, and the processing efficiency is also improved for this purpose.
