Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic assembly device for lighting equipment, and in particular, it is an object of the present invention to provide an assembly equipment most suitable for automatically assembling a lighting equipment for two annular fluorescent lamps. .

Lighting equipment, typically a ring-shaped fluorescent lamp lighting equipment, usually has a ballast, a glow lamp socket,
It has a structure in which a safety bulb socket, a switch, etc. are attached, these are electrically connected to the power line, a reflector is covered and attached to the main body, and a lamp holder is attached to an appropriate location on the periphery. It is used by attaching a glow lamp and safety bulb, and a ring-shaped fluorescent lamp to the lamp holder. Further, an appropriate number of the ballasts and glow lamps are provided depending on the number of fluorescent lamps to be attached.

For example, such lighting equipment is assembled as follows. That is, first, a worker places a bottomed cylindrical main body on a work bench with the opening facing upward, and also places a stabilizer in a predetermined position inside the main body, with the terminal facing upward (opening side). Store it so that Then, fix the stabilizer to the main body using screws, rivets, etc. Next, screw the sockets and switches into predetermined positions inside the main body. Next, wiring is made between each component, and a socket for the annular fluorescent lamp is derived. Next, the reflector is placed over the opening of the main body, the lamp holder is positioned, and the three are integrated with screws. After that, there were beans in the sockets,
The assembly is completed by attaching the glow lamp, mounting the annular fluorescent lamp on the lamp holder, and attaching the socket.

All such assembly is performed manually by workers, which results in poor workability and requires a large number of workers, resulting in inefficiency and high cost.

Therefore, in order to improve the productivity of lighting equipment and reduce manufacturing costs, automatic assembly through mechanization is preferable, but automation requires the supply of each part, the setting of the assembly order, and the positioning of each part during supply. Furthermore, wiring between parts is difficult,
It was difficult to automate. In particular, in the case of lighting equipment for ring-shaped fluorescent lamps, the main body and the reflector are formed in a substantially cylindrical shape with a bottom, and have no directionality, making positioning difficult and automation difficult.

This invention has been made in view of the above-mentioned problems of conventional lighting equipment, and is an improvement on the above-mentioned problems. A ballast supply means that supplies the ballast so that it is on the jig side, and a lighting equipment body that supplies the bottomed cylindrical body onto the ballast set in the assembly jig so that the opening is on the ballast side. a supply means, an assembling means for assembling the ballast and the main body together, and an inverting means for inverting the main body so that the opening is on the non-jig side and setting it on the assembly jig again;
A switch block supplying means for supplying a switch block in which a switch, a socket, etc. are integrated with the wiring into the inverted main body, and assembling the switch block to the main body, and a reflecting plate on the main body, with the opening facing the main body, , a reflector supply means that supplies the flange so that it overlaps with a flange of the main body, and a lamp holder that is supplied onto the reflector is assembled to the reflector and the lighting equipment main body, and the reflector and the lighting equipment main body are also assembled. The lamp holder mounting means constitutes an assembly device.

Then, this invention first supplies the stabilizer onto the assembly jig transferred by a suitable conveyor, then supplies the main body, positions both parts with the assembly jig, and positions both parts. After doing this and joining them together, turn the main body over on the assembly jig and place it again on the assembly jig. Next, supply the switch block with the switch, socket, etc. integrated with the wiring inside the main body. After assembly, the reflector, lamp holder, etc. are sequentially positioned and supplied onto the main body, and then assembled into one body.
