Automatic and precise control structure of cutting knife depth of foil cutting machine for aluminum electrolytic capacitor

Abstract

The invention relates to the field of aluminum electrolytic capacitors, and particularly relates to an automatic and accurate control structure for the cutter depth of a foil cutter for an aluminum electrolytic capacitor. The automatic and accurate control structure for the cutter depth of the foil cutter can rapidly, automatically and accurately control the required cutter depth, and the time required by manual adjustment is saved; and in the aluminum foil cutting process, necessary grinding times are carried out on a cutter due to abrasion, a newly-designed limiting block gauge is accuratelycorrected, and the accuracy of the cutter depth is guaranteed. Meanwhile, a whole cutter shaft device of the foil cutter is stable in work, cutter jumping is avoided, cut burrs are controlled to be below 0.03mm, the phenomenon that the capacitor is short-circuited and loses efficacy due to the fact that the cut aluminum foil burrs are too large is completely avoided, and the product quality of the aluminum electrolytic capacitor is greatly improved. In addition, the possibility that the cutter of the foil cutter is damaged is reduced, and the service life of the cutter is prolonged.

Description

technical field [0001] The invention relates to the field of aluminum electrolytic capacitors, in particular to an automatic and precise control structure for cutting knife depth of a foil cutting machine for aluminum electrolytic capacitors. Background technique [0002] Foil cutting machine is an essential equipment in the production process of aluminum electrolytic capacitors. Cut the metal aluminum foil electrode sheet and electrolytic paper according to the design size of the capacitor, and use it to nail the capacitor core of the aluminum electrolytic capacitor. [0003] At present, in the aluminum electrolytic capacitor manufacturing industry, most of the cutting machines used for cutting aluminum foil and electrolytic paper use the XTF-500 series. With the rapid development of modern electronic information technology, the high requirements for the quality of electronic and electrical equipment and components force electronic components - such as aluminum electrolyti...

AI Technical Summary

Problems solved by technology

[0004] 1. The depth control of the cutter is inaccurate, because it is mainly adjusted by the operator's visual inspection

[0005] 2. The design of the cutter depth adjustment seat is unreasonable. Only one single-side limit seat (left) is used to adjust the cutter depth manually.

Since the upper knife shaft is supported by the left support of the upper knife and the right support of the upper knife for overall movement, it is difficult to precisely control the depth of the cutting knife because only the single adjustment on the left side is used.

At the same time, due to the insufficient manufacturing precision of the structure, the cumulative error is relatively large

In addition, the balance of the left and right supports relative to the lower cutter shaft is also completely adjusted by manual feeling, and there is also a certain error

[0006] 3. During the aluminum foil cutting process, the cantilever structure locking device is used to prevent the upper knife shaft from jumping. Its working state is extremely unstable and must be operated manually by experienced operators.

[0007] Therefore, due to the unreasonable design of the cutter depth control structure of this foil cutter, the cutter depth control is not accurate, and eventually the edge burrs of the cut aluminum foil strips exceed the standard, which directly affects the quality of aluminum electrolytic capacitor products.
