Description

Technical Field

[0001] This utility model relates to the technical field of inkjet printers, and in particular to a handheld inkjet printer. Background Technology

[0002] Currently, handheld inkjet printers are increasingly used in small and medium-sized production activities. They are small in size and easy to move. The printing method of handheld inkjet printers is that the machine body does not move, but the internal print carriage moves along the guide rail to perform the printing operation. Therefore, it is impossible to locate the internal printing area by the markings on the outside of the machine.

[0003] In the existing technology, an open observation window is set on the machine casing of the handheld inkjet printer to determine the printing area of ​​the inkjet printer. However, due to the small size of the observation window, it is impossible to accurately determine the printing area of ​​the inkjet printer. Furthermore, since the observation window is open, there may be some safety hazards. For example, when the inkjet printer is running, the observation window may be approached by other equipment, tools, or personnel, affecting the stability of the equipment or even causing damage to the equipment. The open observation window may also cause more serious physical impacts, affecting the safety of the staff. Utility Model Content

The camera component 310 is used to acquire image information of the printing area with the marking component, and the edge positioning component 330 is used to confirm the boundary position of the printing area.

[0029] The observation window 210 is located on one side of the housing 100 perpendicular to the inkjet opening 110, and the observation window 210 is transparent; the marking component 320 is located on the bottom wall inside the housing 100, the camera component 310 is located on the top wall inside the housing 100, and the edge positioning component 330 is located on one side of the inkjet opening 110 to confirm the boundary position of the printing area.

[0030] In this embodiment, a transparent observation window 210 located on one side of the housing 100 allows for the preliminary determination of the printing area's extent without compromising equipment stability or worker safety. This includes determining whether patterns and / or text exist within the printing area, and whether the printing area falls within a pre-defined frame. Furthermore, by incorporating a camera component, a marker component, and an edge positioning component within the housing, the boundaries of the printing area can be further determined, thereby accurately pinpointing its location.

[0031] In one optional embodiment, the positioning module includes a first edge positioning component and a second edge positioning component; the first edge positioning component is disposed on one side of the inkjet opening and is used to determine a horizontal boundary position of the printing area; the second edge positioning component is disposed on the side of the inkjet opening perpendicular to the first edge positioning component and is used to determine a vertical boundary position of the printing area.

[0032] In the embodiments of this application, such as Figure 2 and Figure 3 As shown, the edge positioning component is used to determine the boundary of the printing area, which includes the upper boundary, lower boundary, left boundary and right boundary of the printing area. The first edge positioning component is used to determine the upper or lower boundary of the printing area, and the second edge positioning component is used to determine the left or right boundary of the printing area. The two boundary positions of the printing area, namely the two boundary positions in the horizontal direction and the vertical direction, can be determined by the first edge positioning component and the second edge positioning component.

[0033] Furthermore, the coding opening includes a first side, a second side, a third side, and a fourth side, wherein the first side and the third side are arranged opposite to each other, the second side and the fourth side are arranged opposite to each other, and the first side is arranged perpendicular to the second side. A first edge positioning component is disposed on the first side or the third side and is located close to the second side or the fourth side.

[0034] In an optional embodiment, the positioning module further includes a third edge positioning component and a fourth edge positioning component; the third edge positioning component is disposed on one side of the inkjet opening relative to the first edge positioning component and is diagonally disposed with respect to the first edge positioning component, for determining the other boundary position of the horizontal aspect of the printing area; the fourth edge positioning component is disposed on one side of the inkjet opening relative to the second edge positioning component and is diagonally disposed with respect to the second edge positioning component, for determining the other boundary position of the vertical aspect of the printing area.

[0035] Furthermore, the third edge positioning component is used to determine the upper or lower boundary of the printing area, and the fourth edge positioning component is used to determine the left or right boundary of the printing area. The first and third edge positioning components can determine the two horizontal boundary positions of the printing area, and the second and fourth edge positioning components can determine the two vertical boundary positions of the printing area.

[0036] Furthermore, the third edge positioning component is disposed on the first or third side and located near the second or fourth side, and the fourth edge positioning component is disposed on the second or fourth side and located near the first or third side.

[0037] Furthermore, the first edge positioning component is located on the first side and close to the second side, the second edge positioning component is located on the second side and close to the third side, the third edge positioning component is located on the third side and close to the fourth side, and the fourth edge positioning component is located on the fourth side and close to the first side.

[0038] Furthermore, the edge positioning component 330 is a light emitter, which can emit light including but not limited to red light, blue light, or green light.

[0039] In this embodiment, the range of the printing area is accurately confirmed by combining the camera component and the edge positioning component. Specifically, the camera acquires the range of the printing area and the marking scale of the marking component 320, and uploads the range of the printing area and the marking scale to the controller. The controller determines the position of the boundary line of the printing area based on the range of the printing area and the marking scale; and determines the position of the boundary line of the printing area through the edge positioning component.

[0040] In one alternative embodiment, the marking component includes two marking elements, one of which is located on one side of the inkjet opening and the other marking element is located on the other side of the inkjet opening.

[0041] In this application, as Figure 4 As shown, the camera component 310 located above the inner wall of the housing 100 acquires an image of the area with the marking component, and uses the area image to identify the range of the printing area.

[0042] The camera assembly 310 includes a camera and a fill light. The lens of the camera faces the coding opening 110. The fill light can be automatically adjusted according to the brightness inside the housing 100 so that the brightness inside the housing 100 reaches a preset value, so that the camera can acquire image information.

[0043] Marking components 320 are respectively set on both sides of the marking opening 110. The interval between adjacent marking scales on one side of the marking component 320 is 20, and the interval between adjacent marking scales on the other side of the marking component 320 is 10. The marking scales of the marking component 320 can be set according to actual needs.

[0044] Furthermore, the lens light of the camera in the camera assembly 310 is focused and mapped onto the image sensor's photosensitive chip. After receiving the image signal, the photosensitive chip converts the image signal into an electrical signal using CMOS (Complementary Metal-Oxide-Semiconductor) technology. The charge is then transferred to the output terminal through a charge-coupled device. After A / D (Analog-to-Digital) conversion, it becomes a digital image signal, which is then sent to a digital signal processor (DSP) or image signal processor (ISP) to process the received data and convert it into a standard image format for transmission.

[0045] In an optional embodiment, the positioning module further includes a follower positioning unit located at the bottom of the inner wall of the housing 100. The follower positioning unit includes a drive member and a follower member. The drive member drives the follower member to move along the horizontal and / or vertical direction of the inkjet opening 110 to determine the position of the inkjet head.

[0046] Furthermore, the follower is a light emitter, which can emit light including but not limited to red light, blue light, or green light.

[0047] To facilitate determining the printing trajectory of the inkjet printer in the printing area, the real-time position of the inkjet head during printing can be determined by a following positioning unit.

[0048] Specifically, the following positioning unit includes a horizontal following component and a vertical following component. The horizontal following component is used to determine the position of the inkjet header in the horizontal direction, and the vertical following component is used to determine the position of the inkjet header in the vertical direction. The horizontal following component and the vertical following component have the same structure, both including a driving component and a following component. The driving component is connected to the following component to drive the following component to move along the horizontal and / or vertical direction of the inkjet opening 110, thereby determining the position of the inkjet header.

[0049] In an alternative embodiment, the device further includes a display screen 400 electrically connected to the controller for displaying the printing range.

[0050] In an alternative embodiment, the display screen is also used to display the real-time position of the inkjet head.

[0051] Specifically, the positioning unit is electrically connected to the controller, and an image acquisition unit is set below the inkjet printer to acquire the working status information of the inkjet printer and the real-time position information of the inkjet printer in the printing area. The image acquisition unit sends the working status information and real-time position information to the display screen 400 through the controller so that the staff can directly observe the working status of the inkjet printer and the real-time position of the inkjet printer in the printing area.

[0052] In one alternative embodiment, the observation window 210 is snap-fitted to the housing 100, or the observation window 210 is magnetically connected to the housing 100.

[0053] In this embodiment, one end of the observation window 210 is rotatably connected to the housing 100, and the other end is detachably connected to the housing 100 via a connector, wherein the connector includes, but is not limited to, a magnetic connector, a snap-fit ​​connector, or a plug-in connector.

[0054] In one alternative embodiment, a detection element is provided between the housing 100 and the observation window, and the detection element is connected to the controller.

[0055] The device also includes an alarm connected to a controller, which is configured to control the alarm to send an alarm signal after receiving information from the detector that the observation window 210 is open.

[0056] In this embodiment, the detection element is located on the end face of the housing 100 that abuts against the observation window 210. When the observation window 210 is in a closed state, the end of the detection element away from the housing 100 abuts against the end of the observation window 210 that is close to the housing 100. The detection element sends information that the observation window 210 is closed to the controller. When the observation window 210 is in an open state, the detection element box controller sends information that the observation window 210 is open. The controller generates a command to stop the inkjet printer based on the information that the observation window 210 is open and controls the inkjet printer to stop working.

[0057] This application uses a transparent observation window 210 to initially determine the printing area of ​​the inkjet printer, and then uses a camera component and an edge positioning component to further determine the specific range of the printing area; the real-time position of the inkjet printer can be observed intuitively through the following positioning unit and the display screen 400; the closed state of the observation window 210 is detected by the detection component, thereby effectively preventing safety hazards during the printing process.
