[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to an automatic assembling apparatus for a lamp which supplies a lamp having mounting bolts to a lamp mounting portion of a vehicle body which conveys an outfitting line of an automobile and mounts the lamp to the lamp mounting portion. It relates to a lamp supply pallet.

[0002]

2. Description of the Related Art In an outfitting line of an automobile, a work of assembling a headlamp to a headlamp mounting portion of a vehicle body includes:
Conventionally, it is all done manually. In other words, a pallet containing a large number of headlamps is prepared at the headlamp assembling position. Take it out and position the headlamp in the headlamp mounting part of the vehicle body.

Then, a mounting bolt provided on the headlamp is inserted into a mounting hole of a bracket provided on a headlamp mounting portion, and a nut is fastened to the mounting bolt by an impact wrench to mount the headlamp on the vehicle body. .

[0004]

As described above, assembling of headlamps has conventionally been performed manually, and assembling is performed in an unnatural posture, the efficiency is low. Assembling the left and right headlamps requires at least two workers.

[0005] Further, since the entire surface of the headlamp is made of a glass lens, care must be taken in handling it, and since the vehicle body is already painted, the headlamp should be prevented from interfering with the painted surface and being damaged during assembly. You need to be careful.

The present invention has been made in view of the above circumstances, and has as its object to accurately position a lamp on a lamp supply pallet when mounting the lamp on a lamp mounting portion of a vehicle body. Another object of the present invention is to provide a lamp supply pallet in an automatic lamp assembling apparatus, which can automatically support an assembling operation on a vehicle body and can improve productivity.

[0007]

According to the present invention, in order to achieve the above-mentioned object, a base which is positioned and mounted on a positioning jig and a lens surface of a lamp which is erected on the base and has mounting bolts are provided. A pair of support bases that support both ends in an upward direction, and are provided on one inner surface of the support base corresponding to the mounting bolts of the lamp, and the upper part has a depth dimension of front.
Length of the mounting bolt protruding from the lamp body
Gradually increased as going down the width and shallower than the dimension
It is formed in a wide angle taper shape, and the lower part is
Gradually decreases as the depth becomes deeper than the length and goes down the width
A two-stage V-shaped groove formed in a tapered shape having a narrow angle and guiding and supporting the mounting bolt, and a positioning pin provided on a support surface of the other support base and inserted into a mounting hole of the lamp. It is characterized by having.

[0008]

When a lamp is inserted from above into a space between a pair of supports of a lamp supply pallet, the mounting bolts of the lamps have a wide angle tapered portion of a V-shaped groove formed on one inner surface of the support, and a narrow angle. The mounting bolts are guided in the order of the tapered portions and supported by the V-shaped grooves, and the mounting holes of the lamp are inserted into and supported by the positioning pins protruding from the support surface of the other support base.

Next, as shown in FIG. 10B, the pusher plate 21 is retracted, and the V-shaped groove 23 is
When the robot arm 10 is moved away from the flange 15b of the
Raise from 6.

When the shutter plate 28 advances by the air cylinder 30 at the same time as this operation, the exclusion hole 29 faces the nut transfer position 26. Therefore, when the nut 15 is left due to a holding error caused by the socket 16, the nut 15 falls directly below the removal hole 29.

In the lamp positioning mechanism 14, the lamp supply pallet 31 is transferred to the positioning jig 32 by the drop lifter 48. The headlamp 5 is supported on the lamp supply pallet 31 by a first support base 34 and a second support base 35.

That is, the headlamp 5 is provided with two stud bolts 37, 37 and two mounting holes 38, 38, and is provided on the inner surface of the first support base 34. Is provided with an inclined surface 39, and the inclined surface 39 is provided with V-shaped grooves 40, 40 at two locations corresponding to the two stud bolts 37, 37,
When setting the headlamp 5 on the lamp supply pallet 31, the stud bolts 37, 37
It is guided from 1 to the lower tapered portion 42 at a narrow angle.

The edge of the main body 5a of the headlamp 5 is provided with a positioning projection 44 on the support surface 43 of the second support base 35.
The headlamp 5 has one mounting hole 38 inserted into the positioning pin 45, the other mounting hole 38 faces the notch 46, and the headlamp 5 has a lens surface 5b on the lamp supply pallet 31. Is set at a predetermined position with the face up.

When the lamp supply pallet 31 on which the head lamp 5 is set is transferred onto the positioning jig 32, the rollers 55, 55, 60, 60 of the first and second clamp mechanisms 51, 52 and the pressing mechanism 53 and 66 is retracted outside the base 50.

When the lamp supply pallet 31 is transferred,
The first clamp mechanism 51 and the second clamp mechanism 52 advance, and the base 33 of the lamp supply pallet 31 is pressed diagonally by the rollers 55, 55, 60, and 60. The base 33 is pressed by 66. Therefore, the lamp supply pallet 3
One base 33 is positioned with its peripheral surface supported at five points.

The two sockets 1 of the nut runner 12
After sucking the nut 15 one by one on each of the nuts 6, 16,
The handle 11 is turned around the rotation shaft 70 so that the grip 11 faces downward. Then, the robot arm 10 of the assembly robot 7
Is further turned, and the gripper 11 faces the lamp supply pallet 31 of the lamp positioning mechanism 14, the robot arm 10 rotates downward.

Then, the headlamp 5 set on the lamp supply pallet 31 is gripped by the gripper 11. That is, since a plurality of suction cups 76 are provided on the holding head 72 of the holding section 11, the lens surface 5b of the headlamp 5 is vacuum-sucked by the suction cups 76.
