Description

[Detailed Description of the Invention] The present invention relates to an insulating sheet mounting device for a capacitor that can automatically supply and mount an insulating sheet to the bottom surface of an electrolytic capacitor, etc.

Conventionally, for example, in an electrolytic capacitor using a metal case, as shown in FIG. The installation is carried out by supplying the insulating sheet 3 into the already installed external sleeve 2 at the insulating sheet installing section of the capacitor assembly machine, and immediately shrinking the external sleeve 2 with hot air. It was fixed inside sleeve 2.
However, as machines become faster, supplying the insulating sheet 3 into the above-mentioned outer sleeve 2 and shrinking the outer sleeve 2 with hot air at the same position is causing instability in the supply of the insulating sheet 3. In addition, there are problems such as shrinkage of the outer sleeve 2 when the insulating sheet 3 is not completely supplied into the outer sleeve 2, which makes it impossible to keep up with the increasing speed of machines. Ta.

The present invention was developed in view of the above points, and is an insulating sheet mounting device for capacitors whose purpose is to stably and reliably supply an insulating sheet to the bottom of a metal case of a capacitor, and to shrink and fix the outer sleeve. It provides: This will be explained below with reference to the drawings. The insulating sheet mounting device for capacitors according to the present invention has two parts: an insulating sheet supply part and an insulating sheet fixing part on a rotary table.
Two consecutive positions are provided. FIG. 2 shows the insulating sheet supply section. In the previous position, the outer periphery of the capacitor 11 is covered with an exterior sleeve 12, and the capacitor 11 is covered with an outer sleeve 12.
A fixed chuck 13 and a movable chuck 14 that hold the
The insulating sheet is then held in the insulating sheet supply section.
At this time, since the outer sleeve 12 only covers the outer surface of the capacitor 11, there is a gap between the outer diameter of the capacitor 11 and the inner diameter of the outer sleeve 12. The insulating sheet 16 is transferred by the sheet supply plate 15 to the bottom surface of the capacitor 11 stopped at the insulating sheet supply section, so that the insulating sheet 16 and the capacitor 11 are substantially concentric. In this state, the lower surface side of the insulating sheet 16 is pushed up by a sheet push-up cylinder 17, and further pressed against the bottom surface of the capacitor 11 by a sheet presser lever 19 attached to a rotary table 18. The work in the position of the insulating sheet supply section is performed by pressing the sheet presser lever 19.
This is until the insulating sheet 16 is pressed onto the bottom surface of the capacitor 11. When this operation is completed, the rotary table 18 rotates and moves to the position of the insulating sheet fixing part. Figure 3 shows the insulating sheet fixing part, and as mentioned above, the capacitor 11
The outer sleeve 12 covered with the fixed chuck 13
While the insulating sheet 16 is held by the movable chuck 14 and pressed by the sheet presser lever 19, the outer sleeve is contracted by the hot air blown from the hot air generator 20. Therefore, the outer sleeve 12 shrinks to cover the top and bottom surfaces of the capacitor 11 shown in FIG.
2. The present invention is as described above.
Since it is composed of two positions, each of which feeds and fixes the insulating sheet 16 separately, it is possible to reliably feed the insulating sheet 16 to the bottom of the capacitor 11, and it is also fully compatible with high-speed machines. This has the effect of completely eliminating the case where the insulating sheet is not reliably supplied into the outer sleeve and is not inserted into the outer sleeve half-heartedly as in the conventional case.

In the embodiment shown in FIG.
Once pressed, remove the sheet push-up cylinder 17,

9 described the configuration for holding down. Although it is possible to use only one of the sheet push-up cylinders 17 and the sheet presser lever 19 without using both, the sheet push-up cylinder 17 is attached to the rotary table 18 and the sheet presser lever 19 is not used. In this case, the cylinder 17 is exposed to the hot air from the hot air generator 20 at the insulating sheet fixing portion shown in FIG. 3, which poses a problem in that the movement of the cylinder 17 is inhibited. Also,
When using only the sheet presser lever 19,
Since the lever 19 moves in a circular motion, when the sheet supply plate 15 presses down the insulating sheet 16 that has moved to the bottom of the capacitor 11, the bottom of the capacitor 11 may be slightly dislodged, resulting in incomplete installation. There are some drawbacks. For these reasons, the present invention uses a sheet push-up cylinder 17.
The insulating sheet 16 can be reliably attached by using both the holder and the sheet presser lever 19. In the embodiment described above, the hot air generator 20 is used to shrink the outer sleeve 12.
A similar effect can be obtained by using a heater or the like instead.
