Description

Technical Field

[0001] The present invention relates to the technical field of seals, in particular to an ink cartridge and a seal machine. Background Art

[0002] As society progresses, traditional seals are no longer able to meet modern needs, leading to the emergence of a variety of new seal machines. These machines can be broadly divided into two categories: those that rely on physical seals, such as seal cylinders that hold physical seals and implement traditional stamping methods; and those that do not, such as rotary printers that use inkjet printing and contain ink cartridges.

[0003] The method of using a seal machine in the prior art is generally as follows: before using the seal machine, the person using the seal first takes a photo of the document to be stamped with a mobile phone, and then uploads it to the system for approval. After the approval of the approval personnel corresponding to the person using the seal, the user can start stamping. When stamping, first place the seal machine on the target stamping area of the document to be stamped, then start the seal machine, and verify the fingerprint. After the fingerprint verification is passed, the seal machine will stamp the target stamping area.

[0004] However, if the document to be stamped is removed from the stamp machine after the fingerprint verification is passed, and another unapproved document is placed under the stamp machine, the stamp will be stamped on the unapproved document. In other words, the stamp machine of the prior art cannot monitor the document being stamped. Summary of the Invention

[0031] Implementation Method 1

[0032] like Figures 1 to 4 As shown, an ink cartridge is used in a stamp machine, which includes a housing and a controller, and is characterized in that it includes: an ink supply mechanism 1, a print head 2 and an image acquisition unit 3; the print head 2 is arranged on the ink supply mechanism 1; the image acquisition unit 3 is located at the lower end of the ink supply mechanism 1, and when the ink cartridge is arranged in the housing, the print head 2 and the image acquisition unit 3 are electrically connected to the controller, and the image acquisition unit 3 is used to acquire a seal image on the inkjet carrier when the print head 2 is jetting ink.

[0033] During specific implementation, the ink supply mechanism 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 seal image, and the image acquisition unit 3 is used to collect the seal 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, prevent users from replacing unapproved documents for illegal stamping, and solve the technical problem that the seal machine in the existing technology cannot monitor the documents in use.

[0034] In this embodiment, the stamp machine can be a rotary printer. The ink supply mechanism 1, print head 2, and image acquisition unit 3 can be conventional technology. The inkjet carrier can be a document to be stamped. While the print head 2 is spraying ink, the image acquisition unit 3 faces the surface of the inkjet carrier in the target stamping area.

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

[0036] In specific implementation, through the above-mentioned structural setting, it is possible to achieve real-time acquisition of the seal image on the inkjet carrier during the inkjet process of the print nozzle 2 while the seal machine housing structure remains unchanged, achieving the effect of stamping and acquiring at the same time. The specific reasons are as follows: First, object distance adaptability. Traditional cameras require a certain object distance (usually several centimeters) to achieve focus, while the distance between the print nozzle 2 and the inkjet carrier is only about one millimeter. If the traditional camera is installed on the ink supply mechanism 1, it will cause the traditional camera to be unable to image clearly, while the contact image sensor can adapt to extremely short object distances (for example, about one millimeter). Second, structural compactness. The contact image sensor has a high degree of integration. It integrates a light source (LED array), a microlens array, multiple photoelectric sensors (CMOS) and a signal processing circuit. It can be directly set near the print nozzle 2 at the bottom of the ink supply mechanism 1, taking up very little space. As a result, it can not only be installed at the bottom of the ink cartridge, but also will not interfere with the seal machine housing and other structures, achieving the effect of stamping and acquiring at the same time. In contrast, the traditional camera module is large in size due to the presence of optical lenses, etc., making it difficult to arrange in the limited space inside the housing. It is understandable that although an endoscopic camera can be used, which is relatively small and can be installed near the print head 2 at the bottom of the ink supply mechanism 1, the endoscopic camera requires a large object distance, which requires the user to hold the stamp machine to increase the object distance to ensure clarity. Therefore, the effect of stamping and capturing at the same time is still not achieved. In other words, the contact image sensor actually obtains the stamp image and the target stamping area through scanning, which is equivalent to taking a photo of the target stamping area with the stamp.

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

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

[0039] In specific implementation, since the printed seal is generally circular, and the rotary printer prints while rotating, after rotating one or more circles, a seal will be formed on the inkjet carrier. Based on this, the image acquisition unit 3 is set to extend from the center of the ink supply mechanism 1 to the edge of the ink supply mechanism 1 to adapt to the radius of the seal. When the ink supply mechanism 1 drives the print head 2 and the image acquisition unit 3 to rotate one or more circles, the printing and acquisition of the seal 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 seal, the image acquisition unit 3 is shorter, and several microlenses, several light-emitting diodes and several photoelectric sensors can be omitted, thereby saving costs.

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

[0041] During specific implementation, during the rotation of the ink supply mechanism 1, the print head 2 first ejects ink to form a part of the seal, and then the image acquisition unit 3 collects the formed part of the seal in real time, achieving the effect of stamping and acquiring at the same time, that is, as soon as a part of the seal is formed, this part will be acquired immediately.

[0042] According to one embodiment of the present invention, the interior of the ink supply mechanism 1 has an ink storage cavity, 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 hole 103; the receiving port 102 is connected to the receiving cavity 101; the image acquisition unit 3 is accommodated in the receiving cavity 101; the ink outlet hole 103 is connected to the ink storage cavity; the print head 2 cover is arranged at the ink outlet hole 103, and the ink inlet hole of the print head 2 is connected to the ink outlet hole 103.

[0043] In specific implementation, the above-mentioned structural arrangement enables the print head 2 and the image acquisition unit 3 to be located in the installation area 100 .

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

[0045] According to one embodiment of the present invention, the installation area 100 has a wiring hole 104, which is connected to the interior of the accommodating cavity 101; the first section 221 covers the wiring hole 104 and is electrically connected to the image acquisition unit 3 at the wiring hole 104; the first section 221 has a first avoidance hole 2211 and a second avoidance hole 2212; the first avoidance hole 2211 is connected to the accommodating port 102, and is used to avoid the accommodating cavity 101; the second avoidance hole 2212 is arranged around the periphery of the nozzle body 21, and is used to avoid the nozzle body 21, and the periphery of the second avoidance hole 2212 is electrically connected to the print nozzle 2.

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

[0047] According to one embodiment of the present invention, a first limiting protrusion is provided on the side wall of the ink supply mechanism 1 , a first limiting hole 2221 is provided on the second section 222 , and the first limiting protrusion is inserted into the first limiting hole 2221 .

[0048] During specific implementation, the position limitation of the flexible circuit board 22 on the side wall of the ink supply mechanism 1 can be achieved through the above-mentioned structural setting.

[0049] According to one embodiment of the present invention, a second limiting protrusion is provided on the side wall of the ink supply mechanism 1, a second limiting hole 2222 is provided on the second section 222, and the second limiting protrusion is passed 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] During specific implementation, the above-mentioned structural setting can further achieve position limitation 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 further included, and the sealing transparent plate 4 is provided to cover the receiving opening 102 .

[0052] In a specific implementation, by covering the receiving opening 102 with the sealing transparent plate 4 , external impurities (such as dust, 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 section 221 covers the installation area 100 and fits therewith.

[0054] In specific implementation, the above-mentioned structural setting not only ensures the connection reliability between the first section 221 and the installation area 100 of the ink supply mechanism 1, but also utilizes the first section 221 to cover the wiring hole 104 to prevent external impurities (such as dust, ink droplets) from entering the receiving cavity 101 through the wiring hole 104.
