[0002] Disclosing the information of this background art section is only intended to enhance the understanding of the overall background of the present disclosure, and is not necessarily regarded as an admission or any form of implication that this information constitutes related art that is already known to those of ordinary skill in the art.

[0003] In printing equipment, printing components all need to cooperate with a vision system to achieve precise printing. In related technologies, large printing equipment adopts separate settings for printing components and vision systems, which are two separate devices. During the printing process, the vision system needs to scan the entire working surface, confirm the printing area, and then form printing data. The printing components then print according to the printing data. Therefore, during the printing process, the sequential working order increases the working time, and there is a time difference between the two components, and they are not synchronized. For various irregular or customized printing requirements, it is necessary to adjust the control of the time difference and operation mode, that is, set different invisible speeds, operation time differences, and the programs for their cooperation through industrial control software. And the writing of the program needs to be completed in advance, with high processing difficulty, high cost, and low work efficiency. Summary of the Invention

Specific Embodiments

[0027] The following specific embodiments illustrate the implementation manners of the present disclosure. Those skilled in the art can easily understand other advantages and effects of the present disclosure from the content disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope protected by the present disclosure.

[0028] Terms such as "upper", "lower", "left", "right", "middle", etc. cited in this specification are only for the convenience of clear narration, rather than to limit the scope of implementation of the present disclosure. The change or adjustment of their relative relationships, without substantial change in the technical content, should also be regarded as the scope of implementation of the present disclosure.

[0029] As Figures 1-3 shown, it shows a visual printing mechanism provided by an embodiment of the present invention. It includes a light-shielding housing 1, and the bottom of the light-shielding housing 1 has an opening 2; a control board 8 is provided inside the light-shielding housing 1, and the control board 8 is respectively connected to control a printing component and a visual component. The printing component is located at the opening 2 of the light-shielding back plate, and it includes a plurality of precision nozzles 3 with the inkjet ports facing downwards. The precision nozzles 3 are connected to an ink cartridge 4 arranged on the back plate through an ink supply pipeline, and the ink cartridge 4 is connected to an ink supply system; the visual component includes a visual bracket 5, and a camera 6 with the visual sensor facing downwards is provided on the visual bracket 5. The visual orthographic projection of the camera 6 is located on the side of the inkjet orthographic projection of the precision nozzle 3;

[0030] This visual printing mechanism integrates the printing component and the visual component, enabling them to run simultaneously during the printing process, improving work efficiency. More importantly, the set distance between the two forms a fixed structure with an unchanged positional relationship. Therefore, when the content of the printed product is determined, only the running speed needs to be set in the control software, which is convenient to operate, reduces the control difficulty, and improves work efficiency.

[0031] In one embodiment, in order to ensure that the camera 6 can accurately perform positioning, a calibration bracket 7 is provided at the bottom of the visual component. The middle of the calibration bracket 7 is a visual window, and the visual window is perpendicularly corresponding to the visual sensor of the camera 6. And referring to Figure 3 shown, the working area of the camera 6 forms a projection range on the surface of the product to be printed through the visual window in the working state.

[0032] In one embodiment, as Figures 4-6As shown in the figure, the ink cartridge 4 includes a main body 401. Inside the main body 401, there is a first chamber 402. At the bottom of the first chamber 402, there is a stirring roller 404. On the front side of the main body 401, there is a transmission gear 405 connected to the stirring roller 404. The transmission gear 405 is driven by a motor arranged outside the main body 401. At the top and bottom of the main body 401, there are respectively an ink injection port 406 and an ink outlet 407 communicating with the first chamber 402. The ink outlet 407 is connected to a precision nozzle 3. On both sides of the main body 401, there are respectively 413 and end plates 414. The end plates 414 have windows corresponding to the first chamber 402 and the second chamber 403 respectively.

[0033] By arranging a stirring device inside the ink cartridge 4, in the case of ink retention, the internal ink is stirred by the stirring device, effectively avoiding the problem of ink deposition, ensuring the printing effect, and at the same time saving the maintenance cost due to ink clogging the pipeline.

[0034] In one embodiment, there is also a second chamber 403 inside the main body 401. On the second chamber 403, there are a reflux port 408 and a circulating ink outlet 409. At the top of the first chamber 402, there is also a circulating ink return port 410. The reflux port 408 is connected to the precision nozzle 3. The circulating ink outlet 409 communicates with the circulating ink return port 410, enabling the ink in the second chamber 403 to be circulated into the first chamber 402. The ink stored when the precision nozzle 3 has not finished printing can also flow back into the second chamber 403 to avoid waste.

[0035] In one embodiment, there is a transmission protection cover 411 outside the main body 401. The protection cover is tightly fixed to the end plate 414. The transmission protection cover 411 includes two splicing blocks. There is a cavity inside between the splicing blocks. The transmission gear 405 is arranged in the cavity. There are grooves on the periphery of the cavity, and sealing rings 412 are arranged in the grooves.

[0036] Among them, the transmission protection cover 411 includes a left half structure and a right half structure. The cavity is located inside the left half structure. There is a shaft in the left half structure for supporting the transmission gear 405. The transmission gear 405 includes a driving gear driven by a driving motor and two driven gears. The two driven gears are respectively fixedly connected to the two stirring rollers 404.

[0037] In one embodiment, there is a fan 9 outside the control board 8. The fan 9 can cool the control board 8. The control board 8 and the ink cartridge 4 are arranged in an overlapping manner and are located above the precision nozzle 3. The overlapping arrangement improves the precision of the components and optimizes the utilization of space.

[0038] In the second aspect of the embodiments of the present disclosure, a printing machine is provided, which is characterized by including the visual printing mechanism according to any one of the above.
