The capping process, which is one of the key processes for capacitor production and manufacturing, plays a decisive role in the production efficiency, product performance and quality of the capacitor, and is usually accomplished by a capping machine.

In the prior art, the end capping process generally comprises the following steps:

(1) Preparing a loading tray, a fixed sticker and an unblocked patch capacitor, then pasting the fixed sticker on any one surface of the loading tray, and spreading the unblocked patch capacitor on the other surface of the loading tray in a manual mode so that the patch capacitor is implanted in a material hole of the loading tray, and pasting any end part of the patch capacitor and the fixed sticker with each other;

(2) Placing the material carrying disc in the step (1) into a capping machine for silver printing so as to achieve capping of the end part of the patch capacitor, which is not mutually adhered with the fixed sticker;

(3) Unloading the loading tray in the step (2) from the end capping machine, drying, adhering another piece of fixed sticker on the other surface of the loading tray, adhering the fixed sticker to the end part of the patch capacitor, which has completed the end capping operation, and tearing off the fixed sticker adhered to the end part of the patch capacitor, which has not undergone the end capping operation, so as to expose the end part of the patch capacitor, which has not undergone the end capping operation;

(4) Placing the material carrying disc in the step (3) into a capping machine for silver printing so as to achieve capping of the end part of the patch capacitor, which is not subjected to capping operation;

(5) And (3) unloading the material carrying disc in the step (4) from the end capping machine, drying, and tearing off the fixed sticker to obtain the paster capacitor with both end parts subjected to end capping operation.
