Description

Technical Field

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

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

[0003] When using a seal, its security is of paramount importance. Therefore, in the existing technology, a camera is installed on the side wall of the top of the seal machine housing. This camera is used to photograph the document being stamped in order to monitor and record the stamping behavior.

[0004] However, because the camera is located on the side wall of the top of the stamp machine's casing, while stamping is done at the bottom of the stamp machine, the camera cannot capture the stamped stamp unless the stamp machine is rotated 90 degrees to a horizontal position so that the camera can be aimed at the stamped stamp. As a result, the stamp machine has to be rotated every time a stamp is captured, leading to low shooting efficiency. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] It should be noted that in the description of this utility model, the terms "first," "second," etc., are used only for descriptive purposes and to distinguish similar objects; there is no sequential order between them, nor should they be construed as indicating or implying relative importance. Furthermore, in the description of this utility model, unless otherwise stated, "at least one" means one or more, and "multiple" means two or more. The use of the term "may" is intended to indicate that any attribute described that is included in "may" is optional.

[0029] In this embodiment, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," "link," and "fix" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this embodiment based on the specific circumstances.

[0030] Implementation Method 1

[0031] like Figures 1 to 4 As shown, this utility model provides a stamp forming unit 1, including: a stamp forming mechanism 11 and a camera 12; the stamp forming mechanism 11 is disposed inside the housing 2 of the stamp machine; the camera 12 is located at the lower end of the stamp forming mechanism 11 and is electrically connected to the controller of the stamp machine, for capturing the document to be stamped to form a stamp image; wherein, when stamping, the camera 12 is located above the target stamping area of ​​the document to be stamped.

[0032] In practice, because the camera is positioned above the target stamping area of ​​the document during the stamping process, it can capture the stamped area. Compared to existing technologies, this eliminates the need to rotate the stamping machine before taking the picture, making the operation more efficient. This solves the technical problem of low efficiency in capturing stamps on documents using existing stamping machines.

[0033] In this embodiment, the image of the stamp may include all the information on the stamped document, such as the text on the stamped document, the stamp, the signature, and the texture of the paper.

[0034] According to one embodiment of the present invention, when the stamping machine completes the stamping and is lifted, the camera 12 is used to capture the document to be stamped to form a stamped image; during stamping, the optical axis direction O of the camera 12 is set at an angle to the surface of the document to be stamped; the angle is configured to reduce perspective distortion of the captured image.

[0035] In practice, since the object distance is relatively large when the stamp is applied by the stamper and then lifted by the user, the problem of small shooting range of camera 12 due to small object distance and blurry shooting due to close object distance can be avoided. In addition, the included angle is configured to reduce perspective distortion of the captured image. The image captured by the camera has less perspective distortion, which is convenient for subsequent optical character recognition (OCR) and can improve the recognition rate of subsequent optical character recognition.

[0036] According to one embodiment of the present invention, the stamping machine is a rotary printer; the stamp forming mechanism 11 includes an ink cartridge 111; the camera 12 is located at the lower end of the ink cartridge 111, and when stamping, the camera 12 has a gap with the surface of the document to be stamped.

[0037] In practice, since the ink cartridge 111 of the rotary printer rotates when stamping, if the camera 12 comes into contact with the surface of the document being stamped, it will not only easily rub and damage the camera 12, but also easily cause ink to stick to the surface of the camera 12, affecting the clarity of subsequent images.

[0038] According to one embodiment of the present invention, the stamp forming mechanism 11 further includes an ink cartridge support 112, which includes a support body 1121 and a positioning tube 1122. The support body 1121 is disposed inside the housing 2 for fixing the ink cartridge 111. The upper end of the support body 1121 has a wiring hole 1210, and the lower end of the support body 1121 has a setting opening 1220. The positioning tube 1122 is disposed inside the support body 1121 and communicates with the wiring hole 1210. The ink cartridge 111 is disposed inside the support body 1121 through the setting opening 1220, and the ink cartridge 111 has a positioning hole. The positioning hole passes through both ends of the ink cartridge 111 along the height direction H of the support body 1121 and surrounds the positioning tube 1122. The camera 12 is disposed in the positioning tube 1122, and the wiring harness of the camera 12 extends from inside the positioning tube 1122 through the wiring hole 1210 to the top of the support body 1121 and is electrically connected to the controller.

[0039] In practice, the positioning tube 1122 not only serves to position the ink cartridge 111, but also provides space for the camera 12 to be installed inside, freeing up space for the camera 12. Furthermore, the internal wiring of the camera 12 is convenient, thus not increasing the overall size of the ink cartridge 111.

[0040] According to one embodiment of the present invention, the ink cartridge 111 includes an ink supply mechanism 1101, the ink supply mechanism 1101 has a positioning hole, and the lower end of the ink supply mechanism 1101 is provided with a protective platform 1011 for protecting the camera 12; the protective platform 1011 has receiving holes 1111 through both ends of the protective platform 1011 along the height direction H of the bracket body 1121; the camera 12 is located in the receiving holes 1111.

[0041] In practice, the protective stand 1011 can prevent the camera 12 from being damaged by accidental contact, thus improving the stability of the product.

[0042] According to one embodiment of the present invention, the lower end face of the ink supply mechanism 1101 includes a first region and a second region; the first region is located at the center of the lower end face of the ink supply mechanism 1101; the second region surrounds the first region; the protective platform 1011 protrudes from the first region; the ink cartridge 111 also includes a print head 1102, the print head 1102 extends radially along the support body 1121, and the print head 1102 includes a first segment and a second segment, the first segment being located in the first region and the second segment being located in the second region.

[0043] In practice, the ink supply mechanism 1101 is used to supply ink to the print head 1102, which is used to print the stamp. The protective platform 1011 protrudes from the first area, so that when the camera 12 takes a picture, it can be aligned with the center of the stamp as much as possible. When the user views the captured image, he / she can find the stamp by directly observing the center of the image, which is convenient for identifying the authenticity of the stamp later.

[0044] In this embodiment, the first region can be circular in shape, and the second region can be annular in shape. The print head 1102 can be of the prior art, with the first and second segments connected together.

[0045] According to one embodiment of the present invention, the camera 12 includes an endoscope camera 12; the included angle is ninety degrees.

[0046] In practical implementation, because the endoscope camera 12 is small in size, it is suitable for structures with limited installation space. Therefore, the camera 12 can be accommodated without changing the main structure of the stamp machine, ensuring the realization of the shooting function. In addition, the 90-degree angle ensures that the camera 12 is facing directly at the camera.

[0047] In this embodiment, the endoscope camera 12 may be a prior art device.

[0048] Implementation Method 2

[0049] This utility model also provides a stamping machine, including: a housing 2, a controller, and a stamp forming unit 1 as described in the above embodiment; the lower end of the housing 2 has an opening 20, the edge of which is used to contact the surface of the document to be stamped; the stamp forming unit 1 is disposed inside the housing 2, and the stamp forming unit 1 includes a camera 12, which is disposed inside the housing 2 and protrudes from the opening 20; when stamping, the camera 12 has a gap with the surface of the document to be stamped. The specific structure, working principle, and beneficial effects of the stamp forming unit 1 are the same as in embodiment one, and will not be repeated here.

[0050] According to one embodiment of the present invention, it further includes: a contact detection unit 3, disposed on the housing 2, for detecting whether the edge of the opening 20 contacts the surface of the document to be printed.

[0051] In practice, since the distance between the camera 12 and the document is small when the edge of the opening 20 is in contact with the surface of the document to be stamped, if a picture is taken at this time, the range of the camera 12 will be small, and the picture will be blurry due to the close object distance. Therefore, a contact detection unit 3 is set to detect whether the stamp machine is lifted, so as to facilitate the subsequent control logic. For example, when it is determined that the stamp machine is lifted, a picture is taken to ensure the clarity of the picture.

[0052] According to one embodiment of the present invention, when the contact detection unit 3 detects that the edge of the opening 20 is in contact with the surface of the document to be printed, the controller controls the camera 12 to turn off; when the contact detection unit 3 detects that there is a gap between the edge of the opening 20 and the surface of the document to be printed, the controller controls the camera 12 to take a picture.

[0053] In practice, the controller is mounted on the housing 2 and interacts with the contact detection unit 3 and the camera 12 via electrical connections. When the contact detection unit 3 detects that the edge of the opening 20 is in contact with the surface of the document to be stamped, the controller receives this signal and controls the camera 12 to turn off to avoid insufficient shooting range or degraded image quality due to close proximity, while also saving energy. When the contact detection unit 3 detects a gap between the edge of the opening 20 and the document to be stamped, the controller controls the camera 12 to take a picture. In this case, the camera 12 can effectively capture the target area, ensuring the integrity and clarity of the image. Therefore, the controller's role is to ensure that the camera 12 automatically turns on or off at the correct time, improving the automation level and working efficiency of the stamp machine.

[0054] According to one embodiment of the present invention, the contact detection unit 3 includes a tactile switch disposed at the edge of the opening 20. The tactile switch can switch between an extended position and a compressed position. When the contact detection unit 3 detects that the edge of the opening 20 is in contact with the surface of the document to be printed, the tactile switch is in the compressed position. When the contact detection unit 3 detects that there is a gap between the edge of the opening 20 and the surface of the document to be printed, the tactile switch is in the extended position.

[0055] In practice, when the edge of the opening 20 of the stamp machine contacts the surface of the printing substrate, the tactile switch is compressed to the compressed position, thereby sending a contact signal to the controller; when there is a gap between the stamp machine and the printing substrate, the tactile switch returns to the extended position, indicating a non-contact state. In summary, the contact status of the stamp machine is detected by the tactile switch.

[0056] In some embodiments, when the contact detection unit 3 detects a gap between the edge of the opening 20 and the surface of the printed document, the controller controls the camera 12 to turn on, and the controller controls the camera 12 to take a picture after a predetermined delay.

[0057] In this embodiment, the predetermined time can be 3 seconds. That is, the camera 12 takes an image 3 seconds after the user lifts the stamp machine, so as to ensure that the user lifts the stamp machine to a certain height before automatically taking a picture, so as to ensure that the shooting range meets the requirements.

[0058] The above are only a few embodiments of this utility model. Those skilled in the art can make various modifications or variations to the embodiments of this utility model based on the content disclosed in the application documents without departing from the spirit and scope of this utility model.
