Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is directed to small floppy disks of 5 inches or less, which have recently been widely used as recording media for personal computers, and whose market has been growing significantly. The present invention relates to an automatic assembly device for disk cartridges, particularly 6.5-inch disk microfloppy disk cartridges, whose exteriors are made of a hard plastic material.

[Prior art]

The 6- and 5-inch size micro-floppy disks, which are currently attracting the most attention among micro-floppy disk cartridges, differ from the conventional 5.25-inch floppy disks (mini-floppy disks) and 8-inch floppy disks in that they have an outer casing. Made of a sturdy plastic case, it is small, lightweight, and handy.
Is it possible to protect the magnetic disk surface when carrying it? This is its biggest feature.

Therefore, unlike conventional floppy disks, 6.5-inch micro-floppy disks have an upper shell (1
) Various parts are attached to the inside of a plastic case called "-F Lua" (2).

The upper shell (1) is made of ultra-high molecular weight polyethylene or Teflon and has a diameter of 9.
A part called the center core pad (3) for lowering the frictional resistance of the rotating shaft, which is a little less than 1111T1, and a part called the lifter (4), which is made of a polyester piece of 20+w+ angle and placed in a predetermined position of the lower shell [2]. The upper shell 11) and lower shell (2) have a diameter of 87 m and are made of a non-woven fabric such as a blend of rayon and polypropylene that is cut into a predetermined shape and is used to protect the magnetic disk.The liner (5) is made of polyacetal, etc. After installing the accidental erasure prevention claw (6), a magnetic disk (7) with a diameter of 3.5 inches that has passed the prescribed inspection is installed on the metal center hub (8).

Place it inside the above shell, and connect the upper shell (1) and lower shell (2) with @sonic waves? Fuse and unite. After that, there is a metal shutter (8) in the window (magnetic head insertion part) where the recording head is taken in and out from the magnetic disk (7). Driving torsion spring (9)? Installing.

A 3.5-inch microfloppy disk cartridge is completed only after the above steps are completed.

[Problem that the invention seeks to solve]

This kind of small micro floppy disk cartridge, which is a molded product made of hard plastic, is smaller and lighter and stronger than 8-inch or 5-inch floppy disks, but the assembly process is complicated, so it is inevitably expensive. Moreover, the stability of quality is also affected.

Also, unlike plastic film or paper, the nonwoven fabric used as liner material is flexible, has a large amount of expansion and contraction, and is difficult to cut. Also, the fact that it is difficult to transfer due to ventilation can also be automated. making it difficult. Conventionally, the process of fusing liners to microfloppy disk cartridges involves cutting each liner into a predetermined shape with a punching blade because the liner has great flexibility and elasticity. ll-difficult,
A common method is to stack approximately several dozen sheets and punch them out using a punching blade.

The reason is that each piece is flexible and not rigid, so the 10th
Liner t32 by cutting die (30) as shown in the figure
The method using one punching device (31) is not stable, including the durability of the punching blade, in order to continuously and stably punch out.

Therefore, if one layer is cut out, it will be thin due to the characteristics of nonwoven fabric.
Because it is flexible and breathable, it can be taken out one by one using a mechanical mechanism.
It is difficult to transfer the liners to the shell, so a method of transferring by vacuum suction is used, but in this case, it is difficult to reliably transfer the liners one by one when the liners are stacked and pulled out.

〔problem? Means for Solving] Does the present invention solve the problems of the above-mentioned prior art? This was devised to solve the problem, and the supply shell transfer device (old A1゜ center core pad sticking device) and lifter sticking device # (old conveyor) were installed in sequence in the flow direction of the 0.

(Figure 7).

The second step 1 is the most characteristic step of the present invention. In this process, the liner is transferred and fused to the upper shell and lower shell at the sixth step in FIG. 1 using a device as shown in FIG.

Here, as a method for continuously pulling out one sheet at a time, the tension and feed pitch accuracy of the nonwoven fabric wound on the supply roll is maintained and controlled, and a roll die cutter (a blade with a predetermined liner shape in a cylindrical roll is The cut liner is vacuum-adsorbed and transferred to an anvil/roll. After being pulled out, the nonwoven fabric is rolled up using a take-up roll. Anobil roll liner supply device? A transfer robot picks up the shell and transfers it to a predetermined position # on the jig pallet. The position at this time is controlled by the position setting of the Anobil roll and the position accuracy control of the transfer robot.

Liner on upper shell and lower shell? After being transferred, spot welding is performed to temporarily secure the liner so that it does not shift when the jig pallet is moved from that position.

Next, after transferring the liner onto the upper shell and lower shell, in the first surface process shown in Figure 1, an ultrasonic sealing material or an R/R heat sealing machine is used to strengthen the adhesion of the liner to the shell. The outer periphery and inner periphery of the liner are heat-sealed. Figure 10 shows the liner m-lid device using ultrasonic sealing. Indicated.

After completion of this process h'-, in the fifth process shown in Figure 1, the upper and lower shells that have been assembled in the above process are transferred one by one from the jig pallet to the case stocker by the Kaoru transfer robot. The shell and lower shell are loaded separately.

This stocker is similar to that shown in FIG. 4 b' - used.

The upper shell and mouth shell transferred to the jig pallet are transferred to a cardboard box, etc., and the empty jig pallet 11
Then, it is automatically sent to the first process again.
