Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a method for assembling a roof lining of a vehicle body.

[0002]

2. Description of the Related Art A roof lining to be mounted on a roof panel of a vehicle body is generally mounted by using equipment (for example, a mounting bracket or a support hook of a sun visor) attached to the roof panel. Conventionally, in such a method of assembling the roof lining, the roof lining is mounted on an arm of an assembling robot, carried into the vehicle, and the equipment is carried into the vehicle one by one by an operator. The operator locked the roof lining to the roof panel together with the roof lining from the lower side of the roof lining, thereby assembling the roof lining to the roof panel. However, in this assembling method, since the worker carries the equipment one by one, the assembling time becomes longer, and the worker is forced to work very hard.

For this reason, there has been proposed a method in which equipment is pre-attached to the roof lining, and then the roof lining is carried into a vehicle and assembled to a roof panel. Such an assembling method is disclosed in, for example, JP-A-11-78521. However, even in the assembling method described in the above publication, the roof lining was assembled to the roof panel by locking the equipment to the roof panel by screwing work or the like. For this reason, the assembly of the roof lining is still troublesome, and an upward screw tightening operation or the like in a narrow car places a great burden on the operator.

[0004]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a method for easily installing a roof lining on a roof panel of a vehicle body.

[0005]

According to the present invention, there is provided a method of assembling a roof lining of a vehicle body having the structure as set forth in the claims. According to the first aspect of the present invention, since the configuration according to the first aspect is provided, the roof lining is interposed between the equipment by engaging the misalignment prevention part of the equipment with the engagement part of the hand part of the assembling robot. Is held by the assembly robot. Since the positional deviation preventing portion and the engaging portion are engaged, the positional deviation preventing portion is less likely to be displaced with respect to the engaging portion, and the roof lining and the equipment are stably held with respect to the assembling robot. As a result, the roof lining can be stably inserted into the vehicle body by the assembling robot, and the roof lining can be easily assembled to the roof panel.

[0006] The roof lining is assembled to the roof panel through the accessory by locking the engaging portion of the accessory to the roof panel. As a result, the roof lining can be locked by the locking portion formed on the previously assembled equipment, and can be easily mounted on the roof panel without the intervention of screws or the like as other components.

[0007] Here, the equipment is an in-vehicle equipment attached to the roof lining, for example, a mounting bracket and a support hook of a sun visor, a cover of an in-vehicle light, a hanger hook, and an assist grip. In addition,
It is preferable that the “position shift prevention part” of the equipment is shaped such that the engagement part formed on the hand part is exactly engaged from the viewpoint of stable engagement. For example, when the engaging portion is convex, the positional deviation preventing portion is concave, and the concave shape is formed in the same shape as the convex shape of the engaging portion. Further, the number of misalignment preventing portions formed on the equipment is not limited to one, and it is preferable that there are a plurality of misalignment preventing portions from the viewpoint of stable holding. For example, when the misalignment preventing portions are formed one by one on both side surfaces of the equipment, the equipment is sandwiched and held by the hand by engaging each with the engagement portion of the hand. . As a result, the roof lining is more stably held, and the roof lining is easily assembled to the roof panel.

The roof lining is assembled by an assembling robot. The assembly may be performed completely automatically without the aid of the operator, or may be performed with the aid of the operator. No problem. In the case where the operator's force is used, for example, the operator remotely controls the hand unit to move the roof lining to just below the mounting location, and moves the hand unit upward at that location, and the This is a form in which the roof lining is moved to a position immediately below the mounting location together with the hand portion while using force, and further moved upward.
