As shown in FIG. 4, the ink ink sealing device 50 proposed by the present invention is mainly composed of a hermetic isolation device 100, a pressure reducing device 200, and a pressure sealing device 300. The hermetically sealed container includes an upper sealing mask η0, a lower sealing mask 120, an ink cartridge positioning seat 30, and a sealing elastic body 140 (for example, 0-ring). The pressure reducing device 200 includes an exhaust pump 21, an air valve 220, and an exhaust line 2 30. The exhaust line 23o is connected to the exhaust pump 2 1 0 and the air valve 2 2 0, And a sealing cover 110 connected to the air valve 2 2 0 and the hermetic isolation device 100. The thermocompression sealing device 300 includes a thermocompression head 310 and a pressurized cylinder 320.

Referring to FIG. 5a and FIG. 5b, an ink cartridge 900 to be sealed is placed in the ink cartridge positioning base 130 with the upper cover 910 of the ink cartridge 900 facing upward and directly below the thermal head 310. At the same time, a sealing film 700 is placed between the upper cover 910 of the ink cartridge 900 and the thermal head 310, and at a position to be sealed at one of the upper cover 9110 of the ink cartridge. This sealing position needs to cover the ink supply hole 911, the air hole 912, and the air channel 913 of the ink tank cover 910. Next, referring to FIG. 6a and FIG. 6b, cover the upper seal cover 110 and close contact with the lower seal cover 120, and use the upper seal cover 110 and the lower

0338-7123TWF; 900052; HAWDONG.ptd Page 8 495445 V. Description of the invention (6) The sealing elastic body 140 (for example, 0-ring) between the sealing masks 120 isolates the outside air. Open the pumping pump 210 and the valve 220, and perform the process of pumping and reducing the pressure ', so that the air pressure in the male and hermetic masks is about 6 40 ± 20 m m-H g, and then the valve 2 2 0 is closed. Then, using a pressurized cylinder 3 2 0, the thermal head 310 which has been preheated to about 18 0 ± 10 is pressed down, and as shown in Fig. 7a and 7b, the sealing film 700 is heated to communicate with the ink cartridge. The 900 upper cover 910 is welded to completely seal the ink supply hole 911, the air hole 912, and the air channel 913 of the upper cover 91 of the ink cartridge. Finally, the ink cartridge completed through this heat-pressing sealing process is shown in Figure 8. Because it undergoes a process of decompression in advance, it can significantly reduce the effect of heat and expansion of the air in the ink cartridge. , There will be no ^ residual phenomenon of small bubbles remaining within the sealing film 7 00, and provide one; uniform and firm adhesion. And because the pressure inside the ink cartridge is less than one atmosphere after sealing, due to the effect of the pressure difference, it is beneficial to improve the sealing effect of the seal cover. It can also reduce the heat pressure. The sealing device 300 has a thermal head 3m. It is between θ and θ to prolong its service life. At the same time, the present invention can be applied to multi-tank ^ ink or ^ water 11 No .: To achieve coffee yield ... to achieve product yield and reduce production ρρ-本 t The present invention has been disclosed above in a preferred embodiment, but it is not intended to be used within the scope of God. The essence of the present invention is only as defined by the scope of the attached patent application.
