Description

Technical Field

[0001] This utility model relates to the field of seal technology, specifically to an ink cartridge and a seal machine. Background Technology

[0002] With the continuous progress of society, traditional seals can no longer meet modern needs, thus giving rise to various new types of seal machines. Seal machines can be broadly divided into two categories: one relies on physical seals, such as seal cylinders, which can contain physical seals and achieve stamping through traditional stamping methods; the other does not rely on physical seals, such as rotary printers, which can contain ink cartridges and achieve stamping through inkjet printing.

[0003] The general method of using existing stamp machines is as follows: Before using the stamp machine, the user first takes a picture of the document to be stamped with their mobile phone, and then uploads it to the system for approval. After the approver corresponding to the user approves it, the user can start stamping. When stamping, first place the stamp machine on the target stamping area of ​​the document to be stamped, then start the stamp machine and verify the fingerprint. After the fingerprint verification is successful, the stamp machine will stamp the target stamping area.

[0004] However, if the fingerprint verification is successful, and then the document to be stamped is removed from under the stamp machine, and another unapproved document is placed underneath it, the stamp will be affixed to the unapproved document. In other words, existing stamp machines cannot monitor documents in use. Utility Model Content

[0031] Implementation Method 1

[0032] like Figures 1 to 4As shown, an ink cartridge is used in a stamp machine. The stamp machine includes a housing and a controller. The cartridge is characterized by comprising: an ink supply mechanism 1, a print head 2, and an image acquisition unit 3. The print head 2 is disposed on the ink supply mechanism 1. The image acquisition unit 3 is located at the lower end of the ink supply mechanism 1. When the ink cartridge is disposed within the housing, the print head 2 and the image acquisition unit 3 are electrically connected to the controller. The image acquisition unit 3 is used to acquire a stamp image on the inkjet carrier when the print head 2 is ejecting ink.

[0033] In practice, the ink supply unit 1 is used to store and supply ink to the print head 2. The print head 2 is used to spray ink onto the surface of the inkjet carrier to form a stamp image. The image acquisition unit 3 is used to acquire the stamp image on the inkjet carrier in real time during the inkjet process of the print head 2, so as to achieve the effect of stamping and acquiring at the same time, preventing users from replacing unapproved documents for illegal stamping, and solving the technical problem that existing stamp machines cannot monitor documents in use.

[0034] In this embodiment, the stamping machine can be a rotary printer. The ink supply mechanism 1, the print head 2, and the image acquisition unit 3 can be existing technologies. The inkjet carrier can be the document to be stamped. When the print head 2 is ejecting ink, the image acquisition unit 3 faces the surface of the target stamping area of ​​the inkjet carrier.

[0035] According to one embodiment of the present invention, the image acquisition unit 3 includes a contact image sensor.

[0036] In practical implementation, the above structural setup allows for real-time acquisition of the stamp image on the inkjet carrier during inkjet printing from the printhead 2, while maintaining the original structure of the stamp machine casing. This achieves the effect of simultaneously stamping and acquiring the image. The specific reasons are as follows: 1. Object distance adaptability: Traditional cameras require a certain object distance (usually several centimeters) to focus, while the distance between the printhead 2 and the inkjet carrier is only about one millimeter. If a traditional camera is mounted on the ink supply mechanism 1, it will result in unclear imaging. The contact image sensor, however, can adapt to extremely short object distances (e.g., about one millimeter). 2. Compact structure: The contact image sensor has a high degree of integration, integrating a light source (LED array), microlens array, multiple photoelectric sensors (CMOS), and signal processing circuitry. It can be directly placed near the printhead 2 at the bottom of the ink supply mechanism 1, occupying minimal space. Therefore, it can be installed at the bottom of the ink cartridge without interfering with the stamp machine casing or other structures, achieving the effect of simultaneously stamping and acquiring the image. In contrast, traditional camera modules, due to the inclusion of optical lenses, are larger and difficult to arrange within the limited space inside the casing. Understandably, while an endoscope camera could be used, its smaller size allowing it to be positioned near the printhead 2 at the bottom of the ink supply mechanism 1, the need for a larger object distance necessitates the user lifting the stamp machine to increase this distance for clarity. Therefore, it still cannot achieve the effect of simultaneously stamping and acquiring the image. In other words, the contact image sensor actually acquires the stamp image and the target stamping area through scanning, essentially taking a picture of the stamped area.

[0037] In this embodiment, a contact image sensor (CIS) is a highly integrated optical imaging device that acquires images by directly contacting the surface of the object being scanned. It is understood that the "contact" in a contact image sensor does not strictly refer to physical pressure contact, but can be an extremely short object distance (e.g., about one millimeter) between the sensor and the object.

[0038] According to one embodiment of the present invention, the image acquisition unit 3 extends from the center of the ink supply mechanism 1 to the edge of the ink supply mechanism 1 along the radial direction of the ink supply mechanism 1.

[0039] In practical implementation, since the printed stamp is generally circular, and since the rotary printer prints while rotating, after one or more rotations, a stamp will be formed on the inkjet carrier. Based on this, by setting the image acquisition unit 3 to extend from the center of the ink supply mechanism 1 to the edge of the ink supply mechanism 1 to match the radius of the stamp, when the ink supply mechanism 1 drives the print head 2 and the image acquisition unit 3 to rotate one or more times, both the printing and acquisition of the stamp are completed. At the same time, since the length of the image acquisition unit 3 is not set to be the same as the diameter of the stamp, the image acquisition unit 3 is shorter, which can omit several microlenses, several light-emitting diodes and several photoelectric sensors, thereby saving costs.

[0040] According to one embodiment of the present invention, the print head 2 and the image acquisition unit 3 are arranged sequentially along the rotation direction R of the ink supply mechanism 1 during ink injection.

[0041] In practice, during the rotation of the ink supply mechanism 1, the print head 2 first sprays ink to form a part of the stamp, and then the image acquisition unit 3 captures the formed part of the stamp in real time, achieving the effect of stamping and acquiring at the same time. That is, as soon as a part of the stamp is formed, that part is immediately acquired.

[0042] According to one embodiment of the present invention, the ink supply mechanism 1 has an ink storage cavity inside, and the lower end of the ink supply mechanism 1 has an installation area 100 and a receiving cavity 101. The installation area 100 has a receiving port 102 and an ink outlet 103. The receiving port 102 is connected to the receiving cavity 101. The image acquisition unit 3 is housed in the receiving cavity 101. The ink outlet 103 is connected to the ink storage cavity. The print head 2 is covered at the ink outlet 103, and the ink inlet of the print head 2 is connected to the ink outlet 103.

[0043] In practice, the above-mentioned structural arrangement ensures that the print head 2 and the image acquisition unit 3 are both located in the installation area 100.

[0044] According to one embodiment of the present invention, it further includes a flexible circuit board 22; the print head 2 includes a print head body 21 and a flexible circuit board 22; the print head body 21 is covered at the ink outlet 103 for spraying ink onto the inkjet carrier; the flexible circuit board 22 includes a first segment 221, a second segment 222 and a third segment 223 connected in sequence; the first segment 221 is disposed at the lower end of the ink supply mechanism 1 and is electrically connected to the print head body 21 and the image acquisition unit 3; the second segment 222 is disposed on the side wall of the ink supply mechanism 1; the third segment 223 is disposed at the upper end of the ink supply mechanism 1 and is electrically connected to the controller.

[0045] According to one embodiment of the present invention, the mounting area 100 has a wiring hole 104, which is connected to the interior of the receiving cavity 101; the first segment 221 covers the wiring hole 104 and is electrically connected to the image acquisition unit 3 at the wiring hole 104; the first segment 221 has a first clearance hole 2211 and a second clearance hole 2212; the first clearance hole 2211 is connected to the receiving opening 102 and is used to avoid the receiving cavity 101; the second clearance hole 2212 is arranged around the periphery of the printhead body 21 and is used to avoid the printhead body 21, and the periphery of the second clearance hole 2212 is electrically connected to the printing printhead 2.

[0046] In practice, the image acquisition unit 3 and the nozzle body 21 are connected by a flexible circuit board 22. That is, the image acquisition unit 3 and the nozzle body 21 share a single cable, requiring only one flexible circuit board 22. This not only saves the cost of setting up an additional flexible circuit board, but also improves integration, reduces the number of parts, and increases assembly efficiency.

[0047] According to one embodiment of the present invention, the side wall of the ink supply mechanism 1 has a first limiting protrusion, and the second section 222 has a first limiting hole 2221, with the first limiting protrusion passing through the first limiting hole 2221.

[0048] In practice, the above-mentioned structural design can be used to limit the position of the flexible circuit board 22 on the side wall of the ink supply mechanism 1.

[0049] According to one embodiment of the present invention, the side wall of the ink supply mechanism 1 has a second limiting protrusion, and the second segment 222 has a second limiting hole 2222. The second limiting protrusion passes through the second limiting hole 2222. Along the height direction H of the ink supply mechanism 1, the first limiting protrusion and the second limiting protrusion are staggered.

[0050] In practice, the above-mentioned structural design can further limit the position of the flexible circuit board 22 on the side wall of the ink supply mechanism 1.

[0051] According to one embodiment of the present invention, a sealing transparent plate 4 is also included, which covers the receiving opening 102.

[0052] In practice, by covering the receiving opening 102 with a sealing transparent plate 4, external impurities (such as dust and ink droplets) can be blocked from entering the receiving cavity 101 and interfering with the optical path of the image acquisition unit 3 without affecting image acquisition.

[0053] According to one embodiment of the present invention, the first segment 221 covers and fits the installation area 100.

[0054] In practice, the above-mentioned structural arrangement not only ensures the reliability of the connection between the first segment 221 and the installation area 100 of the ink supply mechanism 1, but also uses the first segment 221 to block the wiring hole 104, preventing external impurities (such as dust and ink droplets) from entering the receiving cavity 101 through the wiring hole 104.
