Description

Ink cartridge sealing equipment {Ink cartridge sealing equipmentge}

The present invention relates to an ink cartridge and a sealing device for fusion-sealing a film to a lid thereof, and more particularly to a lid such that the ink reservoir of the ink cartridge as well as the ink injection hole on the upper surface of the lid and the air induction path formed around the lid are kept in vacuum. The present invention relates to an ink cartridge and a sealing apparatus in which a film is not peeled off even when an external air pressure condition is changed during transportation or storage by vacuum welding a film on an upper surface.

The ink cartridge 500 mounted and used in the inkjet printer has a lid 520 fused to an upper portion of the body 510 having an ink storage chamber, and an ink injection hole 530 for injecting ink into the lid 520 and the ink cartridge 500. An air induction route 540 is provided around.

The ink cartridge 500 having the above configuration injects ink into the ink storage chamber therein and prevents the ink injected into the ink storage chamber inside the ink cartridge 500 from contacting the air in the air. In order to facilitate long-term storage or transportation, the film P was attached and sealed on the upper surface of the lid 520 on which the ink injection hole 530 and the air induction path 540 were formed.

As described above, in the conventional method of sealing the lid 520 of the ink cartridge 500 using the film P, the operator puts the ink cartridge 500 in which the ink is injected on the workbench of the factory work line, as shown in FIG. The film P having the adhesive layer formed on the back surface was directly adhered to the upper surface of the lid 520 provided with the ink injection hole 530 and the air induction path 540.

However, in the method of sealing the ink cartridge as described above, the ink injection hole 530 and the air induction path 540 of the ink storage chamber and the lid 520 inside the ink cartridge 500 are in a state in which air flows (that is, air Since the film is simply attached to the film (P), air is applied a predetermined pressure between the film (P) attached to the lid (520), the ink injection hole (530), and the air induction path (540). And exist.

As such, when the external temperature increases during transportation or storage while the air is filled in the ink storage chamber of the ink cartridge 500, the ink and air inside the ink cartridge 500 react and evaporate to increase the volume, thereby increasing the pressure. Because of this, even if the film (p) is peeled off, the ink is easy to leak, especially when transporting by aircraft, etc. because the aircraft is flying in the air of several hundred meters below the atmospheric pressure is distributed to the inside of the ink cartridge 500 Since the air pressure (atmospheric pressure) maintained between the ink injection hole 530 and the air induction path 540 is pushed out to a low pressure outside (inside the aircraft), the film P on the upper surface of the lid 520 is easily peeled off. There was a problem.

As the film P is peeled off as described above, the ink injection hole 530 of the ink cartridge 500 is opened, so that the ink leaks, and thus the ink cartridge 500 has a huge economical effect due to the poor treatment of the ink cartridge 500. There was a problem such as loss of phosphorus.

In addition to the above problems, since the operation of sealing the film on the top surface of the lid 520 of the ink cartridge 500 is made by hand, the accuracy and robustness is lowered and productivity is lowered, thereby causing a waste of manpower and cost.

An object of the present invention has been researched and developed in order to solve the above problems, to provide a sealing device of the ink cartridge to enable a safe and robust vacuum welding by welding a portion of the film to the upper surface of the lid of the ink cartridge and vacuum fusion. It is.

Another object of the present invention is to attach the film to the inside of the ink cartridge to the upper surface of the lid to maintain the vacuum, the ink cartridge is not peeled even if the external air pressure conditions change during transportation or storage, thereby improving the reliability of the ink cartridge To provide.
