Description

Technical Field

[0001] This utility model relates to the field of PCB printing equipment, and in particular to a character printing machine for PCBs. Background Technology

[0002] In the PCB manufacturing process, inkjet printing technology is a key step. It is generally used to spray characters, numbers, etc. on PCBs to meet product traceability and process requirements.

[0003] In traditional PCB printing technology, the ink on the PCB surface cannot dry quickly after printing. Typically, gripping devices use suction cups for handling; however, due to the large contact area, this allows the ink to easily come into contact with undried ink, causing smudged text. Waiting for the ink to dry naturally wastes a significant amount of time, reducing worker efficiency. Furthermore, in PCB printing, a single print run is often insufficient, requiring repeated jig movements to ensure complete printing. However, gaps exist between the jig and the PCB, and the PCB's inertia during jig movement can cause misalignment, resulting in misaligned printing positions and affecting print quality.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0017] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features or the order of the technical features.

[0018] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0019] Reference Figures 1 to 8 This utility model discloses a character inkjet printer for PCB boards, including: a base plate 100, a fixture 200, a character inkjet printing device 300, and a curing device 400. The base plate 100 is provided with a guide rail 110 along the left and right directions of the base plate 100. The guide rail 110 is used to guide the movement of the fixture 200. The guide rail 110 is a conventional setting.

[0020] The fixture 200 includes a sliding base 210 and several limiting members 220. The sliding base 210 is slidably disposed on the guide rail 110 in a left-right direction. The several limiting members 220 are all disposed on the sliding base 210, defining a loading space 230. The loading space 230 is used to accommodate a PCB board and define its position. The sliding base 210 is disposed on the guide rail 110 and moves along the extending direction of the guide rail 110. The sliding base 210 is used to mount the several limiting members 220 and defines the loading space 230. The loading space 230 is used to load the PCB board. The limiting component 220 is used to limit the position of the PCB board, ensuring that the PCB board remains relatively stationary with respect to the fixture 200 as the sliding seat 210 slides along the guide rail 110. This prevents printing errors caused by relative displacement between the PCB board and the fixture 200 when the subsequent character printing device 300 prints on the PCB board, thus avoiding affecting product quality. The loading space 230 is used to load the PCB board. The shape and depth of the loading space 230 can be adjusted according to the shape and thickness of the PCB board. The adjustment of the shape and depth of the loading space 230 is specifically achieved by adjusting the installation position and installation height of the limiting component 220.

[0021] The character printing device 300 is disposed above the fixture 200. The character printing device 300 is used to print characters on the PCB board loaded on the loading space 230. The character printing device 300 is a conventional device and will not be described in detail.

[0022] The curing device 400 is disposed above the fixture 200 and behind the character printing device 300. The curing device 400 is used to cure the ink on the PCB board loaded in the loading space 230. The curing device 400 is used to accelerate the curing of the ink on the PCB board. After the character printing device 300 prints ink onto the PCB board, the curing device 400 is installed behind the character printing device 300. Printing and curing are performed simultaneously to prevent the ink from curing in time after printing. This also prevents the ink from shifting due to inertia when the fixture 200 moves back and forth rapidly, which could affect the printing quality.

[0023] In some embodiments, refer to Figures 1 to 8 The curing device 400 is a UV irradiation lamp, which is used to cure the ink on the PCB board. The UV irradiation lamp can also be set as a hot air drying device, an electron beam curing device, or other devices that can quickly cure the ink on the PCB board after inkjet printing. The UV irradiation lamp is a conventional setting and will not be described in detail.

[0024] In some embodiments, refer to Figures 1 to 8The character inkjet printer for this PCB board also includes a transfer device 500, which is used to transfer the PCB board to be printed into the loading space 230. The transfer device 500 is also used to remove the printed PCB board from the loading space 230. The transfer device 500 is used for loading and unloading, saving manpower and improving production efficiency.

[0025] In some embodiments, refer to Figures 1 to 8 The transfer device 500 includes a first stacking frame 510, a second stacking frame 520, and a transfer frame 530. The first stacking frame 510, the second stacking frame 520, and the transfer frame 530 are all mounted on the base plate 100. The first stacking frame 510 is used to load PCB boards to be printed, the second stacking frame 520 is used to load already printed PCB boards, and the transfer frame 530 is used to transfer the PCB boards to be printed loaded in the first stacking frame 510 to the loading space 230. The transfer frame 530 also serves to... The printed PCB boards loaded in the loading space 230 are transferred to the second stacking frame 520. The first stacking frame 510 and the second stacking frame 520 are conventional stacking frames with the same shape and size. The first stacking frame 510 and the second stacking frame 520 can load multiple PCB boards at the same time. It is only necessary to replenish the PCB boards to be printed in the first stacking frame 510 periodically and remove the printed PCB boards loaded in the second stacking frame 520. The transfer frame 530 transfers one PCB board at a time.

[0026] In some embodiments, refer to Figures 1 to 8 The transfer frame 530 includes a lifting module 531, a rotating component 532, and a suction component 533. The rotating component 532 is disposed on the base plate 100. The lifting module 531 is rotatably disposed on the rotating component 532. The suction component 533 is disposed on the lifting module 531 and slides up and down with the lifting module 531. The suction component 533 is used to suction the PCB board and is equipped with suction claws or clamps that can directly grip the PC. The components of the B-board include a gripping component 533 for picking up the PCB board and, in conjunction with the lifting module 531 and the rotating component 532, transferring the PCB board from the first stack frame 510 to the loading space 230. The fully printed PCB board in the loading space 230 is then transferred to the second stack frame 520. The lifting module 531 is an electric lifting module, driven by a servo motor. The gears and racks work together to raise and lower the lifting module 531. The lifting module 531 can also be configured as a belt-driven or screw-driven mechanism. Understandable, refer to Figures 1 to 8The rotating component 532 consists of a base and a bearing. The rotating component 532 is mounted on the rotating component 532 and connected to each other by bearings. The rotational driving force is provided by a servo motor. With the cooperation of the lifting module 531 and the rotating component 532, the suction component 533 moves in the up and down direction and rotates around the bearing on the rotating component 532. The suction component 533 picks up and puts down the PCB board, realizing the movement of the PCB board position.

[0027] It should be noted that, referring to Figures 1 to 8 The suction component 533 is initially positioned above the first stack frame 510. Driven by the lifting module 531, the suction component 533 descends, reaching the PCB board to be printed. It then picks up the PCB board and rises via the lifting module 531. Driven by the rotating component 532, the suction component 533 and the lifting module 531 rotate at a certain angle. The suction component 533, holding the PCB board, is positioned above the loading space 230. Driven by the lifting module 531, the suction component 533 slides closer to the loading space 230, placing the PCB board into the loading space 230. The suction component 533 then rises again under the drive of the lifting module 531. After printing... After completion, the suction component 533 descends under the drive of the lifting module 531, and the suction component 533 abuts against the printed PCB board in the loading space 230. The suction component 533, holding the printed PCB board, rises under the drive of the lifting module 531. The suction component 533 and the lifting module 531 rotate at a certain angle under the drive of the rotating component 532. After rotation, the suction component 533 is located above the second stack frame 520. The suction component 533, holding the printed PCB board, descends under the drive of the lifting module 531. The suction component 533 puts down the printed PCB board. The above process is repeated periodically. It is only necessary to periodically place the PCB board to be printed in the first stack frame 510 and remove the printed PCB board stored in the second stack frame 520.

[0028] In some embodiments, refer to Figures 1 to 8The limiting component 220 includes a driving cylinder 221 and a limiting block 222. The driving cylinder 221 is disposed on the sliding seat 210 and is evenly distributed along the four periphery of the loading space 230. The limiting block 222 is disposed on the push rod of the driving cylinder 221. The driving cylinder 221 is used to drive the limiting block 222 to abut against the PCB board to limit the position of the PCB board. The push rod of the driving cylinder 221 is set towards the loading space 230. The driving cylinder 221 drives the limiting block 222 to move closer to or away from the PCB board in the loading space 230 to clamp or release the PCB board in the loading space 230. It can be understood that the limiting block 222 is provided with a cushioning material such as rubber on the side close to the PCB board to avoid wear on the PCB board.

[0029] In some embodiments, refer to Figures 1 to 8 The character inkjet printer for this PCB board also includes a gantry 600, which is mounted on the base plate 100. The character inkjet printing device 300 and the curing device 400 are both mounted on the gantry 600. The gantry 600 suspends the character inkjet printing device 300 and the curing device 400 above the fixture 200. The gantry 600 is only used to mount the character inkjet printing device 300 and the curing device 400. The installation position of the gantry 600 can be adjusted according to actual working needs. The gantry 600 is a conventional setting and will not be described in detail here.

[0030] In some embodiments, refer to Figures 1 to 8 The gantry frame 600 is equipped with two booms 610, each with a slot 611 at its lower end. Both the character printing device 300 and the curing device 400 are equipped with retaining strips 310, which are inserted into the slots 611. Each retaining strip 310 has a positioning clip 311 that abuts against the boom 610 to restrict the installation position of the corresponding character printing device 300 and the corresponding curing device 400. The two booms 610 are arranged side-by-side in the front-back direction. The retaining strips 310 are inserted into the slots 611 to install the character printing device 300 and the curing device 400 onto the gantry frame 600. Two positioning clips 311 are provided to restrict the installation position of the corresponding character printing device 300 and the corresponding curing device 400.
