Definitions

  • a prior art assembly fixture for manufacturing reflector lamps having a reflector and a light source lamp is referred to in GB-A-2 071 410.
  • reflector and lamp are held by a suitable means while the lamp is adjusted with respect to its position in the X-, Y- and Z-axes relative to the reflector. Control of the adjustment is performed in accordance with the light pattern emitted from the reflector lamp. The positioned lamp is then secured in place in the reflector by an adhesive.
  • said temporary securing means includes means for feeding quick-curing adhesive between the positioned lamp and the reflector.
  • 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.
  • 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.
  • Fig. 1 shows a schematic top view of the machine of the present invention.
  • a reflector mounting system 5 is arranged closely to the position P1 of the turntable 2.
  • 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 to several heads 9 installed on said bonding/testing turntable 3 by the moving system 7. Said heads 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 moving system 10 and then to the next process.
  • a cement feeding system 101 shown in Fig. 2 is arranged closely to the position P2 of said assembling turntable 2.
  • the cement feeding system 101 has the cylinder system 102 and the nozzle 103.
  • the nozzle 103 is vertically moved by the cylinder system 102 and cement is fed from the nozzle 103.
  • the reflector R is moved up to the position P3 and the lamp L is mounted by said lamp mounting system 6.
  • Said reflector R is held by a securing table at the securing side of the holding head 4.
  • Said lamp L is held by a chuck 204 of a moving table 203 at the moving side of the three-axis moving system 500 of the holding head 4.
  • the photodetectors 205c and 205e are arranged symmetrically to the optical axis O.
  • the remaining photodetectors 205b and 205d are arranged on the plane along the Y direction including said optical axis O.
  • the photodetectors 205b and 205d are arranged symmetrically to the optical axis O.
  • the photodetectors 205a through 205e are connected to the arithmetic unit 207 through the signal line 206, which calculates optical displacement of said lamp L from the reflector R according to the signals sent from these photodetectors, moves said three-axis moving system 500, and moves the lamp L to the specified position on the reflector R so that optical positioning will be made.
  • 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.
  • 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.
  • the luminous intensity distribution characteristic of the reflector lamp shows the line-symmetric luminous intensity distribution characteristics centering around the optical axis 0.
  • 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.
  • the measured values B1 and D1 of the photodetectors 205b and 205d are compared with the reference values B0 and D0 to calculate the displacement Yd in the Y direction for optical positioning of the lamp L in the Y direction.
  • 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 Al 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.
  • step S6 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.
  • 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.
  • the heating system 301 has several hot-air nozzles 302 which are vertically moved by a known mechanism.
  • the hot-air nozzles 302 lower to approach the joint between the lamp L and reflector R and hot air is jetted from the hot-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.
  • the adhesive feeding system 401 has several nozzles 404 which are horizontally and vertically moved by the horizontally-moving cylinder system 402 and vertically-moving cylinder system 403.
  • the adhesive feeding system 401 is arranged, for example, closely to the position P6.
  • said nozzles 404 move horizontally and vertically to approach the joint between the lamp L and reflector R and feed guick-curing adhesive such as instantaneous adhesive to the joint in order to temporarily secure the lamp L at the specified position.
  • 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.
  • said three-axis moving system 500 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.
  • the X-axis slider must move carrying 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.
  • the responsiveness 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 500 used for the machine of the present invention does not carry any driving system for motors or the like on sliders so that movable parts will be lightweight and responsiveness will be improved by eliminating the above disadvantage.
