It has become.

  As shown in FIG. 2, a component reversing unit 40 (component reversing unit) is provided at a position adjacent to the front / back discrimination unit 30 in the X direction and adjacent to the finished product pallet 22 in the Y direction. The component reversing unit 40 has a chuck 41 capable of gripping the outer periphery of the optical component 3 with an openable / closable chuck claw, and the rotation axis of the chuck 41 is connected to the motor 42 while being rotatably supported around the X axis. ing.

Next, the operation of the optical component assembling apparatus 10 configured as described above will be described.
First, the lens frame 2 is supplied to the accommodating portion 20a of the component pallet 20, and the three types of lenses 3a, 3b, and 3c are respectively supplied to the remaining three accommodating portions 20b, 20c, and 20d.
In assembling, the conveyance means 11 is driven, and the adsorption cylinder 15 is moved to the accommodating portion 20a. After the lens barrel 2 is sucked and held by the suction cylinder 15, it is transferred to the assembly station 21, and the lens frame 2 is held by the chuck 21a. Thereafter, after the suction is released, the process returns to the parts pallet 20 to suck and hold the lens 3 a of the housing portion 20 b and transfer it to the cleaning unit 23.

  The cleaning unit 23 rotates the chuck 24 together with the lens 3 a after holding the outer periphery of the lens 3 a delivered from the suction cylinder 15 with the chuck 24. In this state, the pedestal 25 moves the chuck 24 upward, and presses the lens 3a against the wiping tape 27 stretched between the two pulleys 26a and 26b with a constant tension with a predetermined contact pressure. At this time, an appropriate cleaning liquid or solvent may be dropped on the lens 3a depending on the material of the lens 3a to be cleaned. In this way, when the chuck 24 rotates while pressing the lens 3a against the wiping tape 27, dust and the like on the surface of the lens 3a are wiped off and cleaned. When wiping with the wiping tape 27 is completed, after the pedestal 25 lowers the chuck 24, it is moved in the X direction to the other end of the guide slit 25a, and the lens 3 is moved directly below the air nozzle 28. Then, air is blown from the air nozzle 28 onto the surface of the lens 3a. Thereby, even if dust or the like remains on the surface of the lens 3a, it is blown off, so that the surface of the lens 3 is further cleaned.

  Thereafter, the chuck 24 is returned to the retracted position on the left side, the cleaned lens 3a is adsorbed to the adsorption cylinder 15, and then the chuck 24 is released. When the suction cylinder 15 receives the lens 3 a, the suction cylinder 15 slides in the X direction and transfers the lens 3 a to the component reversing unit 40. When the chuck 41 of the component reversing unit 40 grips the outer periphery of the lens 3a, the suction cylinder 15 releases the suction and retracts. The component reversing unit 40 rotates the chuck 41 180 degrees around the X axis to reverse the front and back of the lens 3a. The lens 3a is delivered to the suction cylinder 15 in this posture, and the transport unit 11 transfers the lens 3a to the cleaning unit 23 again. The cleaning unit 23 cleans the back surface of the lens 3a in the same manner as described above. When the cleaning of the back surface of the lens 3 a is completed, the lens 3 a is transferred to the front / back discrimination unit 30 by the suction cylinder 15.

  In the front / back discrimination unit 30, the LEDs 33a to 33l are turned on simultaneously, and the camera 31 images the lower surface of the lens 3a. The image obtained at this time is input to the computing device 35, and the computing device 35 performs front / back discrimination using a known image analysis method such as pattern matching. Here, when there is no significant difference between the shape of the front surface of the lens 3a and the shape of the back surface and only the optical coating is different, the LEDs 33a to 33l of the LED array 33 are sequentially turned on, and light of different wavelengths is emitted. The reflected light is sequentially imaged by the camera 31, and the arithmetic unit 35 determines the coating on the observation surface of the lens 3a from the irradiation wavelength and the image at that time. As a result of analysis by the arithmetic unit 35, when it is determined that the direction of the lens 3a is opposite to the preset direction, the lens 3a is transferred to the component reversing unit 40 based on a control signal from the arithmetic unit 35. The lens 3a is inverted in the same procedure as described above.

  Here, it is possible to perform an appearance inspection of the lens 3a together with the determination of the front and back of the lens 3a. That is, the front / back discrimination unit 30 also functions as an appearance inspection unit, and sequentially irradiates the LEDs 33a to 33l having different wavelengths, takes an image with the camera 31, and stores data between the defect-free lens 3a stored in the arithmetic unit 35. If pattern matching or the like is performed, dust or scratches on the lens 3a can be found. Such an appearance inspection can be performed not only when the shape of the lens 3a is significantly different between the front surface and the back surface, but also when only the optical coating is different.

  After the cleaning process using the cleaning unit 23, the reversing process by the component reversing unit 40, and the front / back discrimination process by the front / back discrimination unit 30, the lens 3a is transferred to the assembly station 21 and is correctly placed in the lens frame 2. Inserted in the direction. For insertion, an adhesive for fixing the lens 3a is applied to the outer periphery of the lens 3a via a dispenser (not shown) disposed between the assembly station 21 and the front / back discrimination unit 30. Thereafter, the lens 3b and the lens 3c are sequentially inserted into the lens frame 2 through the same process, and the optical system 1 is assembled.

According to this embodiment, since the cleaning unit 23 is provided, the surfaces of the lenses 3a, 3b, 3c can be automatically cleaned in order immediately before the lenses 3a, 3b, 3c are incorporated into the lens frame 2. . Furthermore, since the component reversing unit 40 is provided, not only the front surfaces of the lenses 3a, 3b, 3c but also the back surface can be automatically cleaned immediately before assembly. Therefore, man-hours can be reduced and productivity can be improved.
Furthermore, since the front / back discrimination of the lenses 3a, 3b, 3c can be automatically performed by the front / back discrimination unit 30, it is not necessary to arrange the front and back of the parts in advance, the preparation man-hours can be reduced, and the productivity can be reduced. Can be improved.
In this way, manual work can be eliminated from the assembly process, so that dust and the like can be prevented from entering the optical system 1. Further, by using image analysis, it is possible to prevent erroneous determination of the front and back of the lenses 3a, 3b, 3c, so that the optical system 1 is not erroneously assembled.

  In addition, the optical system assembled in this way is not limited to the optical system 1 as shown in FIG. For example, as shown in FIG. 7, a plurality of optical components 51, 52, and 53 are bonded using an adhesive applied to the bonding surfaces of the optical components 51, 52, and 53 via a dispenser (not shown) at the assembly station 21. However, even when the optical system 54 is manufactured by stacking, the front and back surfaces of the optical components 51, 52, and 53 can be automatically cleaned, and the front and back can be automatically identified.

When the lens 3 a is assembled to the lens frame 2, the lens 3 a is sucked and held and transferred from the component pallet 20 to the cleaning unit 60. Specifically, after the suction cylinder 15 moves to the cleaning tray 63 that is waiting above the cleaning liquid tank 62 a, the suction holding is canceled and the lens 3 a is placed on the cleaning tray 63.
The cleaning unit 60 lowers the arm 64b and lowers the cleaning tray 63, so that the lens 3a is immersed in the detergent in the cleaning liquid layer 62a. When the lens 3a is cleaned with the detergent, the arm 64b is raised and the cleaning tray 63 is lifted from the cleaning water tank 62a, and then the movable portion 64 is slid and moved to above the water tank 62b. Thereafter, similarly, the lens 3a is immersed in the water tank 62b, the pure water tank 62c, and the drying liquid tank 62d in order. During this time, the detergent attached to the outer surface of the lens 3a is dropped with water in the water tank 62b, the lens 3a is rinsed with pure water in the pure water tank 62c, and the pure water on the surface of the lens 3a is dropped in the drying liquid tank 62d to facilitate natural drying. Become.
Here, the cleaning unit 60 may arrange the air nozzle 28 above or on the side of the drying liquid tank 62d as shown in FIG. 4 in order to dry the lens 3a more quickly.

  In this embodiment, since the cleaning unit 60 is a wet cleaning method, not only dust but also cleaning liquid remaining on the outer surface of the optical component after cleaning, and dirt such as operator fingerprints attached in the previous process, It can be automatically and reliably removed. Other effects are the same as those of the first embodiment.

The present invention can be widely applied without being limited to the above-described embodiments.
For example, the cleaning unit 23 shown in FIG. 4 may include only the air nozzle 28 and only blow air onto the surfaces of the lenses 3a, 3b, and 3c. Alternatively, only the wiping with the pulleys 26a and 26b and the wiping tape 27 may be performed.
