It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0028] In the circuit board manufacturing process, text and characters need to be printed on the surface of the circuit board. Currently, text and characters printed on circuit boards are all black and white patterns. Therefore, current circuit board printers are only capable of printing black and white patterns. When it is necessary to print color patterns on the circuit board, current circuit board printers do not have the corresponding printing capability.

[0029] Therefore, this utility model provides a color printer that can print color patterns on circuit boards by setting multiple printheads and multiple ink cartridges; the printing platform is driven to move in a first direction by a first driving device, and the printing device is driven to move in a second direction by a second driving device, so that the printing device can print on the circuit board line by line, thereby improving printing efficiency and printing effect; by setting a UV irradiation device, the circuit board can be cured while printing, avoiding ink from spreading to other areas and affecting the printing effect.

[0030] The color printer of this utility model embodiment is described in detail below with reference to the accompanying drawings.

[0031] like Figure 1 and Figure 2 As shown in the figure, this utility model embodiment proposes a color printer, which includes a printer table 100, multiple ink cartridges 800, a second drive device 400, and a printing device 500. The surface of the printer table 100 is provided with a printing platform 110 and a first drive device 300 for driving the printing platform 110 to move along a first direction. The printing platform 110 is used to place a circuit board 200 to be printed with a color pattern. The second drive device 400 and the printing device 500 are disposed above the printing platform 110. The second drive device 400 is used to drive the printing device 500 to move along a second direction, where the first and second directions are perpendicular to each other on a horizontal plane. The printing device 500 is provided with a UV irradiation device, and multiple printheads are disposed inside the printing device 500. Each printhead is connected to a corresponding ink cartridge 800 via a pipe, and each pipe is equipped with a peristaltic pump.

[0032] Specifically, in this example, such as Figure 2 As shown, the first direction refers to Figure 2 The front and back directions shown, the second direction refers to Figure 2The left and right directions are shown, meaning the first driving device 300 drives the printing platform 110 to move forward and backward, and the second driving device 400 drives the printing device 500 to move left and right. When printing on the circuit board 200, the circuit board 200 is first placed on the printing platform 110. Then, the first driving device 300 drives the printing platform 110 to move to the initial printing position. Subsequently, the second driving device 400 drives the printing device 500 to move to the circuit board 200 and print on it. It should be noted that when color printing on the circuit board 200, it is printed line by line. That is, after the second driving device 400 drives the printing device 500 to print one line of the circuit board 200 from left to right, the first driving device 300 drives the printing platform 110 to move, so that the next line of the circuit board 200 is moved to the printing position of the printing device 500, and the printing device 500 prints the next line of the circuit board 200. This process is repeated until printing is complete. Meanwhile, the printing device 500 is also equipped with a UV irradiation device. After the second drive device 400 drives the printing device 500 to print a line on the circuit board 200 from left to right, the second drive device 400 will drive the printing device 500 to move from right to left, so that the UV irradiation device can irradiate and cure the just-printed line. This can prevent the ink printed by the printing device 500 from spreading and contaminating other unprinted areas, ensuring the accuracy of the printed pattern. In this application, the color printer has multiple ink cartridges 800, each of which is used to store ink of different colors. At the same time, the printing device 500 has multiple printheads, each of which is connected to a corresponding ink cartridge 800. In this way, when the color printer prints on the circuit board 200, each printhead can spray ink of a different color to meet the printing requirements of color patterns. During printing, a peristaltic pump drives the ink in the ink cartridge 800 into the printhead, enabling the printhead to spray ink.

[0033] It should be noted that the first drive device 300 can use a linear guide rail, a lead screw drive, or a rack and pinion drive to drive the printing platform 110 to move; similarly, the second drive device 400 can use a similar structure to drive the printing device 500 to move.

[0034] Furthermore, such as Figure 1As shown in some embodiments of this application, the printing platform 110 is provided with a plurality of liftable fixing members 600 on its periphery. Before the circuit board 200 is placed on the printing platform 110, the fixing members 600 are in a raised state. After the circuit board 200 is placed on the printing platform 110, the fixing members 600 are lowered to press the circuit board 200 firmly, preventing the circuit board 200 from shifting during the printing process and preventing the circuit board 200 from warping, thus ensuring the normal operation of the printing process. The fixing members 600 serve to position and fix the circuit board 200.

[0035] Furthermore, such as Figure 3 As shown, in some embodiments of this application, the color printer is further equipped with an image recognition device. The circuit board 200 has anti-misalignment target points 210. These anti-misalignment target points 210 enable the image recognition device to align the circuit board 200 before printing, thereby determining the printing position and ensuring printing accuracy. In this example, anti-misalignment target points 210 are provided at all four corners of the circuit board 200, and one of these target points 210 is misaligned along the long side of the circuit board 200, further improving alignment accuracy. Furthermore, the image recognition device can identify the pattern printed on the circuit board 200 by the printing device 500. When the image recognition device detects that the pattern printed on the circuit board 200 by the printing device 500 does not match the required pattern, it can issue an alarm and stop printing.

[0036] Furthermore, in some embodiments of this application, the surface of the circuit board 200 is provided with a white coating, which is made of white ink. The white coating can protect the circuits on the surface of the circuit board 200 on the one hand, and make the colored patterns printed on the circuit board 200 more clearly visible on the other hand.

[0037] Furthermore, in some embodiments of this application, the printing platform 110 is also provided with a temperature control device, which is used to regulate the temperature of the printing platform 110. Specifically, in this example, the temperature control device is used to heat and maintain the temperature of the printing platform 110, so that the circuit board 200 on the printing platform 110 is kept at a certain temperature, which is just enough to allow the ink ejected from the printhead to be quickly pre-cured, preventing the ink from spreading to other places and avoiding contamination of other locations.

[0038] Furthermore, such as Figure 1 As shown, in some embodiments of this application, the color printer further includes a printhead cleaning device 700, which is disposed on one side of the printing platform 110 and is used to clean the printhead. Before or after printing, the printhead needs to be cleaned to prevent clogging, ensure normal printing, and guarantee accurate printing results.

[0039] like Figure 1 As shown, in this example, the printhead cleaning device 700 includes multiple cleaning tanks 710 and ink guide tanks 720 arranged sequentially at intervals. The cleaning tanks 710 contain cleaning fluid and multiple suction nozzles 730. During printhead cleaning, the printing device 500 is first moved above the ink guide tank 720 by the second drive device 400. Simultaneously, the peristaltic pump is turned off, causing the printhead to spray residual ink into the ink guide tank 720. Then, the printhead is moved to the suction nozzles 730, and negative pressure suction is applied to ensure complete removal of residual ink. Finally, the printhead is cleaned by immersing it in cleaning fluid, keeping it clean. Additionally, air vents can be provided around the cleaning tanks 710 for drying the cleaned printhead.

[0040] In some embodiments of this application, the printing device 500 is provided with a lifting assembly for driving the printhead to move up and down. When the printhead is to be immersed in cleaning fluid, the lifting assembly drives the printhead to descend and enter the cleaning fluid for cleaning; after cleaning is completed, the air vent dries the printhead, and the lifting assembly drives the printhead to return to its original position. Alternatively, the printhead can be manually disassembled for cleaning.

[0041] Furthermore, in some embodiments of this application, a print detection area is provided on the periphery of the circuit board. Before printing on the circuit board 200, the printing device 500 needs to perform pre-printing in the print detection area of ​​the circuit board 200. Pre-printing refers to designing a preset pattern. The printing device 500 performs pre-printing in the print detection area according to the preset pattern and a print reference table. Then, the pre-printed pattern is acquired by an image recognition device, and the pre-printed pattern is compared with the preset pattern. If the pre-printed pattern is basically consistent with the preset pattern after comparison, it indicates that all printheads are in normal condition. If the pre-printed pattern differs significantly from the preset pattern, it is necessary to check which printheads are faulty and replace or correct the faulty printheads.

[0042] According to the embodiments of this application, the color printer, by setting multiple printheads and multiple ink cartridges 800, can print color patterns on circuit boards; the printing platform 110 is driven to move along a first direction by a first driving device 300, and the printing device 500 is driven to move along a second direction by a second driving device 400, so that the printing device 500 can print on the circuit board line by line, thereby improving printing efficiency and printing effect; by setting a UV irradiation device, the circuit board can be cured while printing, avoiding ink from spreading to other areas and affecting the printing effect.

[0043] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
