Description

[0001] The present invention relates to an automatic riveting device,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a riveting apparatus, and more particularly, to a new type of automatic riveting apparatus capable of simultaneously riveting a plurality of small rivets to a plurality of products, thereby shortening a working time.

Generally, the term " riveting " refers to an operation of combining two products by rivets. After a rivet is coupled to a through hole formed in the two products, a pressing force is applied to the rivet by a rivet, So that the two products are connected by the rivet.

The riveter for performing such a riveting operation is constituted by a press device that provides a pressing force. The operator places the rivet on the rivet in a state in which the rivet is installed in the through hole of the product to be riveted, So that the corresponding riveting operation is performed.

That is, conventionally, when the operator places the riveting product on the jig and supplies the rivet to each riveting portion of the product, when the jig is provided to the riveter, the rivet is moved up and down, The rivet supplied to the region is riveted. This is as described in Patent Registration No. 10-0188895.

However, since such a conventional conventional rivet is configured to perform only a riveting operation for a specific position among a single product and a corresponding product, only a simple riveting operation can be performed, and only the rivet for a product having a plurality of riveting positions And the whole operation time is long.

Recently, as disclosed in Japanese Patent No. 10-1182738, a plurality of rivets are provided, and then each of the rivets is repeatedly provided to each of the rivets so that the riveting operation for the products placed on the corresponding seating jig is performed collectively In addition, each of the seating jigs can be horizontally moved so that each individual riveting operation can be performed in each of the rivets.

However, the above-described conventional technique is merely a single unit of a plurality of rivets in a single apparatus, and is not a practical automation apparatus since it is practically a continuous arrangement of a plurality of rivets.

Furthermore, the above-described conventional technique has been accompanied by a cost increase for additional provision for each driving element as the configuration for horizontal movement of the seating jig to seat the product is provided separately, and the maintenance cost is also proportional thereto There is a drawback in that it is inevitably increased. Further, in the case of a rivet used in a small product such as a mobile phone, since a very small rivet having a very small size is provided, a riveting operation of the rivet requires a very precise transfer structure. There is a disadvantage in that the cost is increased.

In addition, in the above-described conventional technique, the worker has installed the seating jig on which the product is placed in a work area performed by each of the rivets, and then, the riveting operation for each product proceeds by collectively operating the respective rivets Therefore, the riveting operation can not be performed during the replacement operation of installing the seating jig for mounting the new product after the worker takes out the seating jig of the completed work product, However, there is a problem in that the number of working people can not be increased.

In addition, since each of the seating jigs is configured to move independently of each other, the above-described related art has a disadvantage in that the size of the whole apparatus can not be increased because each of the rivets must be disposed in consideration of the moving region of each seating jig.

SUMMARY OF THE INVENTION The present invention has been made in order to solve various problems of the prior art described above, and it is an object of the present invention to provide a method of manufacturing a small rivet which can simplify the overall structure while simultaneously riveting a plurality of small rivets, And to provide an automatic riveting apparatus according to a new type which can shorten the working time and minimize the number of the working personnel by allowing the work to proceed.
