Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a parts supply device for assembling products in a clean room.

[0002] In recent years, parts have been automatically supplied when assembling products due to increased efficiency and automation of production. On the other hand, some products are affected by dust, so they are assembled in an environment that prevents dust, such as a clean room. Therefore, it is required to be able to automatically supply parts even in a clean room.

0003

BACKGROUND OF THE INVENTION Conventionally, air feeders have been used as a method for automatically feeding parts to assembly positions. Taking the supply of screws as an example, the screws stored in the parts feeder are aligned, and the screws are supplied one by one through a pipe hose extending to the tip of the tightening jig using air pressure. Then, the fed screws are chucked and held at the tip of the tightening jig at the assembly position, and screw tightening operations are performed continuously.

[Problem to be solved by the invention] However, in environments where it is necessary to prevent dust generation, such as in clean rooms, dust is removed by circulating air and using ultra-high performance air filters, resulting in a large amount of dust generation. There is a problem in that the above-mentioned air feeder cannot be used and automatic supply of parts is difficult. Furthermore, there is a problem in that the size of the product increases when a plurality of screws are supplied to the product.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a parts supply device which is small in size and can automatically supply parts while preventing the influence of dust.

[0006]

[Means for Solving the Problems] The above object is to provide a parts supply device that supplies predetermined parts to assembly members and assembles them in a clean room, in which a predetermined number of said predetermined parts are supplied from a parts reservoir and supported With the support part and the part,
an assembly section for assembling the assembly members that are positioned and moved; a holding means for sucking a predetermined number of the parts supported by the support part and supplying the parts onto the assembly members; and the holding means. This problem is solved by having a configuration that includes a moving means for moving the component to the support section and to the assembly section.

[0007]

[Operation] As described above, the holding means is moved by the moving means between the support part that supports the component and the assembly part. This holding means attracts a predetermined number of parts on the support part and supplies them onto the assembly member. This makes it possible to automatically supply parts without using air in a clean room while preventing the influence of dust. Moreover, by making it possible for the holding means to hold a plurality of parts, an increase in size can be avoided and a small-sized parts supply apparatus can be achieved.
