JPS59189082A - Method for instructing assembly of parts - Google Patents

Abstract

PURPOSE:To instruct directly the assembling position of parts and to reduce assembling errors by irradiating selectively spot-like light according to models and specifications to the position on a working table or base material where the parts are to be assembled. CONSTITUTION:Many seats 1a for assembling parts are projected atop an assembling jig 1 of a working table. Spot lights 2 of the same number as the number of the seats 1a are installed above the jig 1. The lights 2 are so formed that each thereof can irradiate each of the seats 1 by spot-like light 2a. The lights 2 are connected to a selective control device which selects the lights 2 to irradiate and instruct the seats 1a to be disposed with parts 3. Phototubes or laser light may be used for the lights 2 and means consisting of convex lenses fitted to punched holes are also usable in obtaining the spot-like light.

Description

Detailed Description of the Invention (Industrial Application Field) The present invention provides a method for assembling parts to indicate the assembling position when assembling parts at a desired position depending on the model of an article to be assembled. It concerns the method of instruction.

(Conventional technology) Generally, it is a model on an automobile welding assembly line.

Various items with different specifications are mixed together and assembled, so depending on the item to be assembled, such as the model of the floor panel and the specifications, the parts to be assembled to it, such as two Nando's, may be assembled in different positions. It is.

However, since this kind of assembly uses a common assembly jig, the worker must judge the number and assembly position of the parts to be assembled depending on the model of the product, etc.
This work was extremely complicated.

Conventionally, as a method of instructing the operator on the number and assembly position of the parts to be assembled, the fact that different parts have different parts shelves has been used to indicate the number and position of the parts to be assembled by lighting up the parts shelf. Some devices are equipped with a display panel that mimics the shape of an article to be assembled, and a lamp at a required assembly position is lit on the panel. However, all of these methods are indirect instruction methods, and the operator has to work while looking at the display panel, etc., which poses the problem of making assembly errors.

It is also conceivable to place NANDs at all assembly positions on the floor panel, regardless of the model, and then operate only the welding machine at the necessary assembly position, but if you do this, A problem arises in that the welding current is shunted to an adjacent NAND that does not require assembly and is welded.

(Object of the Invention) The present invention is notable for providing a method for instructing parts assembly that can greatly reduce parts assembly errors.

(Structure of the Invention) The present invention illuminates the position on the workbench or base material where the parts are to be placed with spot light, switching the light according to the model and specifications of the article to be assembled, thereby assembling the parts. This allows you to directly indicate the location.

(Example) Embodiments of the present invention will be described below with reference to the drawings.

1 and 2 are for explaining one embodiment of the present invention. In the figures, 1 is an assembly jig which is a workbench, and this is used to assemble an article to be assembled, for example a floor panel. It is used to weld and secure parts to be attached, such as nuts. A large number of component assembly seats 1a are protruded from the upper surface of the assembly jig 1, and nuts 3 are inserted onto the component assembly seats la by the worker as appropriate according to the model and specifications of the floor panel. Placed.

Further, the same number of spotlights 2 as the component assembly seats 1a are installed above the assembly jig 1, and each of the spotlights 2 illuminates each of the component assembly seats 1a with a spot-shaped light 2a. It can be irradiated.

Each of the spotlights 2 is connected to a spotlight switching control device. This spotlight switching control device is for switching and irradiating the spotlight 2 to instruct the component assembly seat 1a where the nut 3 should be placed, and is composed of a vehicle type switching control section 4 and a spotlight switching device 5. has been done.

The vehicle type switching control section 4 provides vehicle type information 6, that is, the model.

Upon receiving information according to the specifications, it outputs a switching signal 4a for turning on the spotlight 2 facing the position where the nut 3 is to be assembled. Further, the spotlight switch 5 has an opening/closing switch for each of the spotlights 2, and is configured to open/close the opening/closing switch in response to a switching signal 4a from the vehicle type switching control section 4.

In the method of this embodiment, when the vehicle type information 6 is input to the vehicle type switching control section 4, the control section 4 selects the current model.

A switching signal 4a according to the specifications is output, and the spot-no-dorite switch 5 receives the switching signal 4a and turns on a predetermined opening/closing switch, thereby setting the position where the nut 3 of the assembly jig 1 is to be placed. The component assembly seat 1a will be irradiated. - As a result, the worker can place the nuts 3 only on the parts assembly seats 1a at the required positions, then place the floor panel covering these nuts and operate the welding machine to assemble the required part of the floor panel. position ・Grot 3 can be welded.

FIG. 3 is a diagram for explaining another embodiment of the present invention. In the figure, the same reference numerals as in FIG. 1 indicate the same or equivalent parts, and 7 is various pattern plates, which can swing between the front position and the side position of the spotlight 2. . Further, punch holes are formed in each pattern plate 7 to correspond to nut assembly positions according to the model and specifications of the floor panel. Furthermore, this pattern plate 7 is connected to a pattern switching controller 8, which uses an output signal 4a of the vehicle type switching control section 4 to move the pattern plate 7 according to the vehicle type to a position in front of the spotlight 2. It is designed so that it can be rotated.

In the method of this embodiment, the pattern switching controller 8 receives the output signal 4a from the vehicle type switching control section 4 and rotates the pattern plate 7 to a position in front of the spotlight 2 in accordance with the current vehicle type information. Then, the light from the spotlight 2 passes through the punched holes in the pattern plate 7 and illuminates only the necessary component assembly seats 1a of the assembly jig 1.

In both of the above embodiments, the case where the spotlight 2 is used has been explained, but it may also be possible to use a phototube or a laser beam, and a convex lens may be fitted into a punched hole as a means for obtaining spot light. You can also use a different one.

Further, in both of the above embodiments, the case where the NAND is welded to the lower surface of the floor panel has been described, but it goes without saying that the present invention can also be applied to the case where the NAND is welded to the upper surface of the floor panel.

(Effects of the Invention) As described above, according to the instruction method for assembling parts according to the present invention, the position where the parts should be placed on the workbench or base material is determined according to the model and specifications of the article to be assembled. Since the switch was switched to irradiate with a spot-like light, mistakes in assembling parts can be easily detected (
There are effects that can be reduced.

Claims (1)

[Claims] (1) When assembling single or multiple parts to the base material at different positions on the workbench depending on the model and specifications of the article to be assembled, a spot-shaped light is emitted onto the workbench or the base material. Parts assembly is an instruction method that is characterized by changing the projection position and illuminating the position to be assembled according to the model and specifications.
