Regeneration method for ink box

Abstract

The invention relates to a regeneration method for an ink box for an ink-jet printer. The ink box comprises an outer shell formed by buckling an upper shell and a lower shell and at least two independent ink cavities formed in the outer shell, wherein an ink injecting opening of each ink cavity is covered by the upper shell, and an ink spray opening of each ink cavity passes through the upper shell and exposes; a groove is formed on the outer side, which is covered by the lower shell, of the upper shell; an ink box chip is fixed in the groove; and the ink box chip is electrically connected with a plurality of chip contacts which are arranged on the outer surface of the upper shell and correspond to the ink cavities. The regeneration method comprises the following steps of: disassembling the box, welding the chip, punching, cleaning, drying, assembling, injecting ink and sealing the ink injecting openings. By the regeneration method, residual liquid in the regeneration process of the ink box can be eliminated, the ink in the ink box is prevented from being leaked due to the residual liquid, and the chip in which integral print information in the full state is welded, so that the chip has high compatibility with a printer.

Description

technical field [0001] The invention relates to a method for recycling printing consumables, in particular to a method for regenerating ink cartridges used in inkjet printers. Background technique [0002] The ink cartridge is mainly a container that stores a certain amount of ink. Usually, the ink cartridge is detachably installed in the inkjet printer. When printing, the ink stored in it can be continuously supplied to the print head for printing. When the ink is exhausted, replace it with a new ink cartridge, and the printer can continue to print. At present, with the rapid development of electronic office, the printing volume of printers has increased significantly, and the replacement frequency of ink cartridges is relatively high. Moreover, the specifications of ink cartridges used by different types of inkjet printers are not the same, resulting in a large number of discarded ink cartridges. In fact, the service life of ink cartridges is far longer than the life of u...

AI Technical Summary

Problems solved by technology

[0006] However, there are two major defects in the ink cartridge regeneration method disclosed above: one is that the used chip cannot be completely restored to a usable state through rewriting, and after the chip is rewritten, some program information cannot be written. , resulting in the incompatibility between the rewritten chip and the printer, so the regenerated ink cartridge cannot be used on the printer; second, after the ink cartridge is cleaned, there are some gaps in the structure of the ink cartridge, and the liquid in the gap (including residual cleaning Liquid or water) is not easy to be removed, for example, there is easy liquid accumulation between the two ink chambers, or liquid accumulation in the small hole on the circuit board of the ink ejection port, many bad effects brought by the remaining liquid in the ink cartridge will be It will appear in the finished product of the ink cartridge. For example, the hot pressing process in the final packaging process of the ink cartridge is operated under high temperature conditions. The high temperature will evaporate the remaining water in the ink cartridge, and some water will evaporate to the packaging bag, making The inside of the packaging bag is full of water vapor and cannot be delivered normally. The moisture on the circuit board at the ink jet port will evaporate and seep into the sticker pasted on the ink jet port. As a result, when the finished ink cartridge reaches the user's hands, ink leakage is found in the newly purchased ink cartridge
