Abstract
Description
- This invention relates to a method for manufacturing reflector lamps comprising a reflector and a light-source lamp. More particularly, the present invention relates to a machine for effectively manufacturing reflector lamps through automatic and efficient assembling of reflectors with lamps.
- In the conventional method for manufacturing the above reflector lamp, a reflector and lamp are set to a positioning device and the lamp is set to a specified position of the reflector by the device, and the lamp is positioned by turning on the lamp to detect the luminous intensity distribution of the light projected forward from the reflector by several illuminance meters and moving the lamp up to to the position where the specified luminous intensity distribution is obtained while an operator monitors values detected by these illuminance meters.
- For this method, however, the operator requires dexterity and it takes time to position the lamp. Therefore, the operation is inefficient.
- The lamp is normally secured to the reflector with adhesive or cement. However, it takes time for cement to cure. Therefore, the lamp should be held at the above specified position of the reflector until the cement cures.
- Thus, the positioned reflector and lamp must be set to the positioning device until the cement cures. Fore this reason, manufacturing of reflector lamps becomes further inefficient. The present invention improves the above disadvantage and provides a machine for efficiently manufacturing reflector lamps.
- The machine of the present invention has the following features for achieving the above object.
- The machine of the present invention has several holding heads. These holding heads are installed, for example, on a turntable so that they will be moved by rotation of the turntable. These holding heads have a reflector and light-source lamp and three-axis moving means for moving the lamp around the reflector in directions of three axes X, Y, and Z which are orthogonal each other.
- Also, the machine of the present invention has lamp positioning means for turning on said lamp, detecting luminous intensity distribution of the light projected forward from the reflector, automatically operating said three-axis moving means according to the luminous intensity distribution, and moving said lamp to the specified position.
- Moreover, the machine of the present invention has temporary securing means for temporarily securing said lamp for the reflector.
- The temporary securing means includes, for example, cement feeding means for feeding a small amount of cement to the lamp-mounting portion of the reflector and heating means for heating and curing the cement after the lamp is positioned.
- According to another embodiment, said temporary securing means includes means for feeding quick-curing adhesive between the positioned lamp and the reflector.
- In the machine of the present invention, said holding heads are moved, for example, by rotation of the turntable and the reflector is mounted before a small amount of cement is fed by said cement feeding means and then the lamp is mounted, turned on, and moved to the specified position by said lamp positioning means according to the luminous intensity distribution of the emitted light.
- Then the cement is cured by said heating means and the lamp is temporarily secured at the specified position before the assembly of the reflector and lamp is finally secured by the cement newly fed in another process.
- According to an embodiment of the present invention, the three-axis moving means of said holding head has only a slider to separately move in the X, Y, and Z directions and its moving system and motors for driving them are not installed on said turntable but are installed at the securing side. Therefore, these driving motors are connected with the three-axis moving means only when the holding head moves to the place for positioning said lamp.
- This invention can be more fully understood from the following detailed description when taken in conjunction with the accompanying drawings, in which:

- Embodiments of the present invention are described below according to drawings.
- Fig. 1 shows a schematic top view of the machine of the present invention.
- This machine has the
common base 1. The assemblingturntable 2 and the bonding/testing turntable 3 are installed on thebase 1. Several (e.g. eight) holdingheads 4 are arranged on the periphery of said assemblingturntable 2. Theturntable 2 intermittently stops every 1/8 turns and each stop position is shown by any one of P1 through P8. On these positions P1 through P8, operations to be mentioned later are executed. - The three-axis moving system to be mentioned later is installed on each of said holding heads to move the installed lamp around the reflector in three directions of X, Y, and Z which are orthogonal each other for optical positioning.
- A reflector mounting system 5 is arranged closely to the position P1 of the
turntable 2. - A reflector R (e.g. dichroic mirror) is mounted on each
holding head 4 by the reflector mounting system 5. - A
lamp mounting system 6 is arranged at the position P3 and the light-source lamp L (e.g. halogen lamp) is mounted on eachholding head 4 at the above position. - As mentioned later, the reflector R and lamp L are assembled on the assembling
turntable 2 with the specified positional relation and temporarily secured by cement. - A moving system 7 is arranged at the position P8 of the assembling
turntable 2 and the temporarily-assembled reflector lamp is moved toseveral heads 9 installed on said bonding/testing turntable 3 by the moving system 7. Saidheads 9 are moved according to rotation of said bonding/testing turntable 3, cement is fed and dried, and test is executed. Reflector lamps passing the test are moved to the ejecting conveyer 8 by the movingsystem 10 and then to the nest process. - Reflector lamps failing the test are ejected by the
disposing system 11. - A
cement feeding system 101 shown in Fig. 2 is arranged closely to the position P2 of said assemblingturntable 2. Thecement feeding system 101 has thecylinder system 102 and thenozzle 103. - The
nozzle 103 is vertically moved by thecylinder system 102 and cement is fed from thenozzle 103. - When the reflector R mounted on said holding
head 4 is moved to the position P2, saidnozzle 103 lowers to feed a small amount of cement to several portions (e.g. three portions) inside the lamp installing portion of the reflector R. - Then, the reflector R is moved up to the position P3 and the lamp L is mounted by said
lamp mounting system 6. - Said cement is applied between the mounted lamp L and reflector R. Then, the reflector R and lamp L are moved to the position P4 where the lamp L is optically positioned to the reflector R. The configuration of the
positioning system 201 is described below according to Figs. 3 through 5. - Said reflector R is held by a securing table at the securing said of the
holding head 4. Said lamp L is held by the chuck 204 of the moving table 203 at the moving said of the three-axis movingsystem 500 of theholding head 4. - Several (e.g. five) photodetectors 205a through 205e are arranged in front of the held reflector R or at the light projection side. The photodetector 205a is arranged on the several axis of the reflector R or the optical axis O. Two the
photodetectors 205c and 205e are arranged on the surface along the X direction including the optical axis O. - The
photodetectors 205c and 205e are arranged symmetrically to the optical axis O. The remainingphotodetectors photodetectors - The illuminance of the light reflected and forward-projected by the reflector R is detected by these photodetectors and the illuminance distribution is measured.
- The photodetectors 205a through 205e are connected to the
arithmetic unit 207 through thesignal line 206, which calculate optical displacement of said lamp L from the reflector R according to the signals sent from these photodetectors, move said three-axis moving system 500, and move the lamp L to the specified position on the reflector R so that optical positioning will be made. - The following is the description of the optical positioning. Fig. 4 is a flow chart of the above operation. The lamp L is turned on in the step S1 and illuminance is measured by each of said photodetectors in the step S2. The measured value is input to the
arithmetic unit 207 and computed in the step S3. This operation is executed, for example, as shown below. - The normal illuminance distribution characteristic when the lamp L is at the correct optical position as shown in Figs. 5A and 5B is previously input to the
arithmetic unit 207. Also, illuminance values at positions of photodetectors (e.g. illuminance values C0 and E0 in the X direction shown in Fig. 5A and illuminance value B0 and D0 in the Y direction shown in Fig. 5B} are stored in the arithmetic unit. - In this embodiment, the luminous intensity distribution characteristic of the reflector lamp shows the line-symmetric luminous intensity distribution characteristics centering around the optical axis 0.
- As shown by a broken line in Fig. 5A, if the lamp L is displaced from the reflector L and the luminous intensity distribution characteristic is displaced, the measured values C1 and E1 of said
photodetectors 205c and 205e are changed. Thus, the luminous intensity distribution characteristic or the displacement Xd of the lamp L in the X-axis direction is calculated according to the change of C1 and E1 in the step S4 and optical positioning of the lamp L in the X-axis direction is executed by moving the said three-axis moving system 500 in the step 5. - Though the above description is made for the X-axis direction, the same is true for the Y-axis direction.
- As shown in Fig. 5B, the measured values B1 and D1 of the
photodetectors - Optical positioning in the Z-axis direction is made by the measured value of the photodetector 205a arranged at the center of the above mentioned. That is, after said positionings in the X- and Y-axis directions are completed, the measured value A1 of the photodetector 205a on the optical axis O is compared with the reference value A0 to calculate the displacement Zd in the Z-axis direction as shown in Fig. 5A or 5B and the three-
axis moving system 500 is operated corresponding to the calculated displacement for optical positioning of the lamp L in the Z-axis direction. - It is confirmed in the step S6 that positioning of them is completed before the lamp L is temporarily secured at the specified position in the step S7.
- In this embodiment, the lamp L is temporarily secured by said heating system for heating the fed cement.
- Fig. 6 shows a schematic configuration of the
heating system 301. - The
heating system 301 is arranged closely to said position P5 or closely to the position P6 or P7 according to necessity. Theheating system 301 has several hot-air nozzles 302 which are vertically moved by a known mechanism. - When the lamp L and reflector R positioned in said process are moved to these positions, the hot-
air nozzles 302 lower to approach the joint between the lamp L and reflector R and hot air is jetted from the hor-air nozzles 302 to heat and cure the previously-fed cement and temporarily secure the lamp L at the specified position. In this case, it is permitted to turn on the lamp L in order to heat the cement. - Fig. 7 shows another embodiment to temporarily secure the lamp L.
- The
adhesive feeding system 401 is also shown in Fig. 7. Theadhesive feeding system 401 hasseveral nozzles 404 which are horizontally and vertically moved by the horizontally-movingcylinder system 402 and vertically-movingcylinder system 403. Theadhesive feeding system 401 is arranged, for example, closely to the position P6. - As mentioned above, when the assembly of positioned lamp L and reflector R is moved to the position, said
nozzles 404 move horizontally and vertically to approach the joint between the lamp L and reflector R and feed quick-curing adhesive such as instantaneous adhesive to the joint in order to temporarily secure the lamp L at the specified position. - When the instantaneous adhesive is used to temporarily secure the lamp as shown in Fig. 7, the cement feeding system in Fig. 2 and the heating system in Fig. 6 are necessary.
- The assembly in which the lamp L is positioned and temporarily secured is moved to the
head 9 of the bonding/testing turntable 3 by said moving system 7, where the lamp L is secured by cement and tested. - In said embodiment of the present invention, said three-
axis moving system 501 uses a special structure. That is, conventional popular three-axis moving system of this type mounts, for example, a Y-axis slider freely moving in the Y-axis direction, a motor for driving the Y-axis slider, and a driving system such as a decelerator on an X-axis slider freely moving in the X-axis direction, and also mounts a Z-axis slider freely moving in the Z-axis direction and its driving system on the Y-axis slider. - For the above structure, the X-axis slider must move by mounting very heavy units because the Y-axis slider and its driving system and the Z-axis slider and its driving system are mounted on the x-axis slider.
- Thus, the responsibility of the X-axis slider decreases. Therefore, when the conventional three-axis moving system is used, the lamp positioning speed decreases and the operation speed also decreases.
- The three-
axis moving system 501 used for the machine of the present invention does not mount any driving system for motors or the like on sliders so that movable parts will be lightweight and responsibility will be improved by eliminating the above disadvantage. - Figs. 8 through 13 show the configuration of the three-
axis moving system 500. Thenumber 501 represents a frame and theframe 501 is installed on said assembling table 2. - Axis-direction moving systems or feed
screws frame 501, which are rotatably supported by thebearing 505. - The feed screws 502
trough 504 are orthogonal each other and arranged in the X-, Y-, and Z-axis directions respectively. TheX feed screw 502 arranged in the X-axis direction connects with theX slider 507 through thenut 506. - The
X slider 507 is slidable guided in the X-axis direction by theX guide 508 installed on saidframe 501 in the X-axis direction. Therefore, theX slider 507 is moved in the X-axis direction according to rotation of theX feed screw 502. - The Y-axis-directional
Y feed screw 503 and the Z-axis-directionalZ feed screw 504 connect with the Y-axis-directional Y slider 510 and Z-axis-directional Z slider 512 through thenuts - Said
Y slider 510 is slidably guided in the Y-axis direction by the Y-axis-directional Y guide 513 installed on saidframe 510 through theroller guide 514. - Therefore, the
Y slider 512 is moved in the Y-axis direction according to rotation of theY feed screw 503. - Said
Z slider 512 is slidably guided by theZ guide 515 installed on theframe 501 in the Z direction and moved in the Z-axis direction according to rotation of theZ feed screw 4. - The
guide groove 516 or the Y-axis-directional slide guide is formed on saidX slider 507. - The
first slide 517 slidably fits theguide groove 516 and move in the Y-axis direction. - The
roller guide 518 or the X-axis-directional guide is installed on saidY slider 510. The movable part of theroller guide 518 connects with saidfirst slide 517 through the connectingmember 519. - The
cross roller guide 520 or the X- and Y-axis directional guide is installed on saidX slider 512. - The
cross roller guide 520 comprises tworoller guides - The movable part of the
roller guide 520b connects with thesecond slide 521. Themovable part 523 is supported on thesecond slide 521 through thesupport axis 522. - Said
support axis 522 is slidably inserted into the hole 24 formed on saidfirst slide 517. - The member at the securing side or the mounting
plate 528 is arranged under the assemblingturntable 2 on which saidframe 501 is installed. - The
motors plate 528. Theelectromagnetic clutches frame 501. - Therefore, when the electromagnetic clutch is separated, said
frame 501 and the member installed on the frame can be moved together with the assemblingturntable 2. - Only one set of these motors is installed on said position P4 and these motors are connected to the transfer axis at the side of the
frame 501 through said electromagnetic clutches only when the three-axis moving system 500 of each holdinghead 4 moves to the position P4. - The
motor 525 is an X motor to drive the three-axis moving system in the X-axis direction. TheX motor 525 is connected to thetransfer axis 532 through theelectromagnetic clutch 529. Thetransfer axis 532 is connected to saidX feed screw 502 through thebevel gear 533. - Therefore, said
X feed screw 502 is driven by theX motor 525. Themotor 526 is a Y motor to drive the three-axis moving system in the Y-axis direction. TheY motor 525 is removably connected to the transfer axis 535 through theelectromagnetic clutch 530. The transfer axis 535 is connected to theY feed screw 503 through thebevel gears - Therefore, the
Y feed screw 503 is driven by theY motor 526. - The
motor 527 is a Z motor to drive the three-axis moving system in the Z-axis direction. - The
Z motor 527 is connected to saidZ feed screw 504 through theelectromagnetic clutch 531. Therefore, theZ feed screw 527 is driven by theZ motor 527. - The three-
axis moving system 500 operates as mentioned below. When the holdinghead 4 reaches the position P4, each of said motors is connected to each axis through the electromagnetic clutch. - Then the
X feed screw 502 is rotated by theX motor 525 and theX slider 507 moves in the X-axis direction. Thus, thefirst slider 517 moves in the X-axis direction. Consequently, thesupport axis 522,second slide 521, and connectingmember 519 move in the X direction, and the movable part 23 holding the lamp L moves in the X direction. - The
Y feed screw 503 is rotated by theY motor 526 and theY slider 510 moves in the Y direction. Therefore, thefirst slider 517 moves in the Y direction. Consequently, thesupport axis 522,second slide 521, and connectingmember 519 move in the Y direction and said movable part moves in the Y direction. - Also , the
Z feed screw 504 is rotated by saidZ motor 527 and theZ slider 512 moves in the Z-axis direction. Therefore, thesecond slider 521 andsupport axis 522 moves in the Z direction and themovable part 523 moves in the Z direction. - Thus, the
movable part 523 holding the lamp L is moved in the X-, Y-, and Z-directions and positioned. - For the three-axis moving system having the above configuration, neither driving motor nor parts are mounted on each slider and the movable part is lightweight. Therefore, the lamp L is quickly positioned with a high responsibility.
- Also, the structure is simple because only one set of driving motors is installed on the position P4 as mentioned above. The present invention can be applied not only to said embodiment but to various embodiments unless they are out of the gist of the present invention.
