If the forward and backward movement attempt is the third or less in the seventh transmission coupling step (S370), the optical coupling attempt number variable in the eighth transmission coupling step (S380) is changed to 0 (Zero), and the transmission module support unit 290 The process of automatically reversing backwards and forwards again to complete the optical coupling retries is completed, and the number of forward and backward movement attempts is increased by one time and is moved to the second transmission coupling step (S320).

In the seventh transmission coupling step (S370), if the forward and backward movement attempt is not less than the third or less, the worker action process of the ninth transmission coupling step (S390) is performed, and the worker automatically moves back and forth up to three times. If it is, the defect is processed and regular work is performed with the next sample.

If the optical output value of the optical fiber core portion of the receiver in the fifth transmission coupling step (S350) does not match the quality level, the process of increasing the number of optical coupling attempts variable in the tenth transmission coupling step (S391) once After this progresses to the third transmission coupling step (S330).

On the other hand, in the fourth step (S400) of the receiver optical coupling process, the receiving optical fiber end 601 of the optical cable 600 is the receiving light quantity detection sensor for the optical coupling of the transmitter of the receiving optical quantity measuring device 380 for the optical coupling of the transmitter After detaching from contact with 384, an epoxy adhesive 801 is applied to the receiving optical fiber end 601, and the receiving portion of the optical cable 600 is seated on the receiving optical cable tip seat 250.

And the receiving optical fiber end 601 of the optical cable 600 is introduced into the inner space of the transmitter lens block 272 located on the upper surface of the receiving transmitter optical module plate 270.

The control unit 400 transmits an electrical signal through the transmitting unit optical module plate 270, and the electrical signal is transmitted to the core portion of the receiving optical fiber end 601 by light through the transmitting optical cable 600, and receives the receiving optical fiber. Light transmitted to the core portion of the end 601 is transmitted as an electrical signal to the receiving transmitter optical module plate 270 through the receiving transmitter lens block 272.

While maintaining the electrical signal transmission state as described above, the control unit 400 moves the receiving optical cable tip seating part 250 to the left and right, and the electric power transmitted to the receiving transmitter optical module plate 270 while moving the receiving module support part 290 back and forth. Judge the signal.

The control unit 400 determines the electric signal transmitted to the receiving transmitter optical module plate 270, and when it is determined to be an appropriate electric signal output value, the control unit 400 moves left and right of the receiving optical cable tip seating unit 250 and moves forward and backward of the receiving module support unit 290. Stop.

The control unit 400 utilizes the receiving current measuring device 360 for receiving optical coupling and the current sensing sensor for receiving optical coupling of the receiving unit 362 of the receiving current optical coupling. It can be measured indirectly.

The receiver current coupling device 360 for receiving optical coupling includes a receiver current coupling sensor 362 for receiving optical coupling and receiving current measurement sensors 362 for receiving optical coupling. And a sensor cylinder part 366 formed to raise and lower the measurement sensor seat part 364 and the reception current measurement sensor seat part 364 for the receiver optical coupling. In the present embodiment, two current measuring sensors are used, but the present invention is not limited thereto, and the number may be variously changed according to a circuit.

The receiver current coupling sensor 362 for the receiver optical coupling includes a transmitter optical module after the optical fiber end 602 of the optical cable 600 is inserted into the receiver lens block 372 of the receiver optical module device 310. An optical signal arrives from the optical element of the receiver optical module device 310 and flows to the optical fiber end 602 by selecting and contacting an appropriate pin on the substrate among currents flowing through the optical switching unit and the optical receiver plate 370 to the receiver optical module plate 370. Indirectly measures the amount of light.

In this state, the controller 400 moves the UV lamp unit 279 so that the UV lamp 379a is moved above the transmitter lens block 272, and then the UV lamp 379a causes the light to be irradiated to transmit the lens. The epoxy adhesive 801 is cured at the core portion of the receiving optical fiber end 602 of the optical cable 600 located inside the block 272.

For more information on the coupling process between the optical cable 600 and the optical module that is carried out by the receiver through the control unit 400, see the first receiving coupling step (S410) to the tenth receiving coupling step (S491). ) Process.

The first receiving coupling step S410 is a process of initializing the number of optical coupling attempts and the number of front and rear movements to zero, and a second receiving couple that proceeds after the first receiving coupling step S410. The ring step (S420) is a process of determining whether the receiver current output value matches the quality level, and the third receiving coupling proceeds when the receiver current output value does not match the quality level in the second receiving coupling step (S420). Step S430 is a process of determining whether the optical coupling attempt is 10th or less, and when the optical coupling attempt is 10th or less in the third receiving coupling step S430, S440 is a process of repeating movement to the left and right by applying a binary search algorithm and repeating about 10 times until the receiver current output value matches the quality level, and the fourth receiving coupling step (S440). ) The fifth receiving coupling step (S450) is a process of determining whether the receiver current output value matches the quality level, and proceeds when the receiver current output value matches the quality level in the fifth receiving coupling step (S450). In the sixth receiving coupling step (S460), after the optical fiber movement stops, the UV module 279a is irradiated to the optical module transmitter lens block 272 to cure the epoxy part of the transmitter lens block 272 and the optical cable 600. This is a process of fixing the lens structure of the overall optical module transmission device.

When the receiver current output value matches the quality level in the second receive coupling step S420, the flow moves to the sixth receive coupling step S460.

In addition, when the optical coupling attempt is not the tenth or less in the third receiving coupling step (S430), the process of determining whether the forward and backward movement attempt in the seventh receiving coupling step (S470) is the third or less is performed.

When the forward and backward movement attempt is the third or less in the seventh reception coupling step (S470), the optical coupling attempt number variable in the eighth reception coupling step (S480) is changed to 0 (Zero), and the receiving module support unit 290 is changed. The process of automatically moving backward and then moving forward again to complete the optical coupling retry preparation is performed, and the number of forward and backward movement attempts is increased by one time and moved to the second step S200.

When the forward and backward movement attempt is not the third or less in the seventh reception coupling step (S470), the worker action process of the ninth reception coupling step (S490) is performed, and the worker automatically moves back and forth up to three times. If it is, the defect is processed and regular work is performed with the next sample.

If the receiver current output value does not match the quality level in the fifth receiving coupling step (S450), a process of increasing the optical coupling attempt number variable, which is the tenth receiving coupling step (S491), is performed once and then again performed. Proceeds to three receiving coupling step (S430).

Through the above-described operation of the present invention, the coupling process between the optical cable 600 and the optical module, which has been conventionally performed manually, can be performed accurately and quickly, thereby improving productivity and reducing costs.

In the present invention, a structure for moving the module support part 290 forward and backward as a modification of the forward and backward movement structure is omitted, and a recess 231 is formed in the lower portion of the optical cable holder 230, and the recess 231 is seated. The holder rail portion 233 is formed in the longitudinal direction of the optical cable 600, it is also possible to move back and forth along the holder rail portion 233 in a state in which the optical cable 600 is fixed to the optical cable holder 230.

In the modified example of the front and rear movement structure, the holder rail portion 233 is also fixed when the tip of the holder rail portion 233 is fixed to the optical cable tip seating portion 250 so that the optical cable tip seating portion 250 is slightly moved from side to side. Finely moved as described above, in this state, the holder portion of the optical cable 600 is moved back and forth along the holder rail portion 233.

On the other hand, Figure 15 is a schematic perspective view showing that the robot arm for applying the adhesive of the present invention is further formed.

The present invention does not apply the epoxy adhesive 801 to the periphery of the transmitter lens block 272 or the core portion of the optical cable 600 by hand, the robot arm 1000 having a link structure 1100 to control the control unit ( It is formed to be controlled at 400, and the epoxy adhesive 801 can be automatically applied to the robot arm 1000 by forming the epoxy adhesive 801, the outflow tube 1200 and the sensor unit 1300.
