Description

Small gear assembly

The present invention relates to a small gear assembling apparatus, and more particularly, to allow the first reduction gear and the second reduction gear installed in the CD-ROM to be automatically assembled to prevent damage and wear.

In general, the reduction gear which acts as a deceleration gear among the CD-ROM gears has a reduction ratio equal to the number of teeth of the first reduction gear and the number of teeth of the second reduction gear by a combination of the first reduction gear and the second reduction gear. Due to the nature of the product, it is not an integral gear, so the first and second reduction gears must be assembled and put into the CD-ROM assembly line.

That is, when assembling the first and second reduction gears installed in the conventional CD-ROM, first, the first reduction gear 1 as shown in FIG. 1A is mounted on a work jig (not shown) of a fixed block type. After assembling the second reduction gear 2 as shown in FIG. 1B to the first reduction gear 1 and inserting the buffer plate 22 as shown in FIG. 1C into the upper surface of the second reduction gear 2, By assembling the spring for the second reduction gear 2 and the shock absorbing plate 22 into a unit, the first and second reduction gears 1 and 2 that are assembled as shown in FIG. 2 are separated from the work jig. To the CD-ROM assembly line.

However, the first and second reduction gears (1) and (2) for reducing the speed between the gear part and the driving gear of the conventional dongjeol should be put into the assembly line of the CD-ROM as a one-piece gear. Since it is complicated and needs to be put in after the assembly by hand in the sub-line, it takes a lot of assembly time, and work efficiency is reduced, and productivity is reduced. In particular, the first and second reduction gears (1) and (2) are assembled correctly. Since it is impossible to check whether or not the first and second deceleration gears (1) and (2), which are poor in assembly, have been introduced into the assembly line, there have been many problems such as lowering the reliability of the product.

The present invention is to solve the above problems, it is possible to automatically assemble the first reduction gear and the second reduction gear installed in the CD-ROM to prevent damage and wear to shorten the assembly time and improve work efficiency It is an object of the present invention to provide a small gear assembling apparatus capable of increasing the productivity by means of the above, as well as checking whether the first and second reduction gears are assembled correctly.
