[0002] A character printer is a printer that integrates inkjet printing and curing of PCB characters. Character printers can print various graphics such as PCB characters, QR codes, ink blocks, and circuit diagrams.

[0003] Existing character printers include a stationary stage, an X-axis moving module, a Y-axis moving module, a printing module, and a platform. The X-axis moving module and the platform are both mounted on the stationary stage, where a PCB board is placed. The printing module is mounted on either the X-axis or Y-axis moving module and can move above the platform to print graphics onto the PCB. To secure the PCB, existing character printers typically install multiple positioning components on the stationary stage corresponding to the four sides of the platform. These positioning components are used to position the PCB. However, because these positioning components occupy a significant amount of space on the stationary stage, the platform space is not utilized efficiently, resulting in a relatively large size for existing character printers.

[0049] The existing character printer 100 includes a fixed stage 10, an X-axis moving module, a Y-axis moving module, a printing module, and a platform 40. Both the X-axis moving module and the platform 40 are mounted on the fixed stage 10. A PCB board 70 is placed on the platform 40. The printing module is mounted on either the X-axis or Y-axis moving module and can move above the platform 40 to print graphics on the PCB. To fix the PCB board 70, the existing character printer 100 typically mounts multiple positioning components on the fixed stage 10 corresponding to the four sides of the platform 40. These positioning components are used to position the PCB. However, because the positioning components occupy a significant amount of space on the fixed stage 10, the space on the platform 40 is not utilized efficiently, resulting in a relatively large size for the existing character printer 100.

[0050] This utility model discloses a character printer 100. Please refer to [link / reference]. Figure 1 , Figure 4 , Figure 6 and Figure 7 The character printer 100 proposed in this utility model includes a fixed stage 10, a platform 40, a moving mechanism 20, and a printing module. The moving mechanism 20 is movably mounted on the fixed stage 10 and includes a first X-axis moving module 21 and a first Y-axis moving module 22. The first X-axis moving module 21 is mounted on the fixed stage 10 and part of its structure can move along the length direction of the fixed stage 10. The first Y-axis moving module 22 is mounted on the fixed stage 10 and part of its structure can move along the width direction of the fixed stage 10. The printing module is mounted on the first X-axis moving module 21, and the platform 40 is movably mounted on the first Y-axis moving module 22.

[0051] The platform 40 is equipped with a second X-axis moving module 41, a second Y-axis moving module 42, multiple first adsorption heads 43, multiple second adsorption heads 44 and multiple third adsorption heads 45. The second X-axis moving module 41 is arranged along the length direction of the platform 40, and the second Y-axis moving module 42 is arranged along the width direction of the platform 40.

[0052] Multiple first adsorption heads 43 are disposed on the second X-axis moving module 41 and externally displayed on the platform 40, and multiple second adsorption heads 44 are disposed on the second Y-axis moving module 42 and externally displayed on the platform 40. The second X-axis moving module 41 is used to drive the multiple first adsorption heads 43 to move along the length direction of the platform 40, and the second Y-axis moving module 42 is used to drive the multiple second adsorption heads 44 to move along the width direction of the platform 40.

[0053] Multiple third adsorption heads 45 are located on the edge of the platform 40 and are visible on the platform 40. Multiple first adsorption heads 43, multiple second adsorption heads 44 and multiple third adsorption heads 45 are all connected to a negative pressure source.

[0054] In one embodiment, the negative pressure source can be a fan, which can be located outside the fixed platform 10. The fan is used to communicate with a plurality of first adsorption heads 43, a plurality of second adsorption heads 44, and a plurality of third adsorption heads 45, so that the plurality of first adsorption heads 43, a plurality of second adsorption heads 44, and a plurality of third adsorption heads 45 can adsorb and fix the PCB board 70 on the platform 40.

[0055] The printing module is mounted on the first X-axis moving module 21, allowing it to move left and right relative to the platform 40. In one embodiment, the platform 40 is mounted on the first Y-axis moving module 22, allowing it to move back and forth on the fixed stage 10. Both the first X-axis moving module 21 and the first Y-axis moving module 22 on the moving mechanism 20 of this invention can operate independently, thereby increasing the moving speed of the moving mechanism 20.

[0056] Please see Figure 4 , Figure 6 and Figure 7The second X-axis moving module 41 drives multiple first suction heads 43 to move along the length direction of the platform 40, and the second Y-axis moving module 42 drives multiple second suction heads 44 to move along the width direction of the platform 40. This allows the second X-axis moving module 41 and the second Y-axis moving module 42 to adjust the positions of the multiple first suction heads 43 and multiple second suction heads 44 according to the size of PCB boards 70 of different sizes, thereby adsorbing and fixing PCB boards 70 of different sizes and improving the applicability of the character printer 100. Moreover, the second X-axis moving module 41, the second Y-axis moving module 42, the multiple first suction heads 43, the multiple second suction heads 44, and the multiple third suction heads 45 are all located inside the platform 40, making reasonable use of the space inside the platform 40 and reducing the space occupied by the fixing table 10, thus facilitating the miniaturization of the character printer 100.

[0057] Please see Figure 3 The second X-axis moving module 41 drives multiple first adsorption heads 43 to move to the left, and the second Y-axis moving module 42 drives multiple second adsorption heads 44 to move backward, so that multiple first adsorption heads 43, multiple second adsorption heads 44 and multiple third adsorption heads 45 together adsorb and fix the smaller PCB board 70.

[0058] The second X-axis moving module 41 drives multiple first adsorption heads 43 to move to the right, and the second Y-axis moving module 42 drives multiple second adsorption heads 44 to move forward, so that multiple first adsorption heads 43, multiple second adsorption heads 44 and multiple third adsorption heads 45 together adsorb and fix the larger PCB board 70.

[0059] Optionally, the number of the first adsorption head 43, the number of the second adsorption head 44, and the number of the third adsorption head 45 can be three, four, five, etc. This invention does not limit the number of the first adsorption head 43, the number of the second adsorption head 44, and the number of the third adsorption head 45.

[0060] Specifically, please refer to Figure 6 and Figure 7 The second X-axis moving module 41 includes a first driving assembly 411, a first lead screw, and a first moving seat 413. The first driving assembly 411 is connected to the first lead screw, and the first lead screw is driven to the first moving seat 413. A plurality of first adsorption heads 43 are disposed on the side of the first moving seat 413 away from the fixed platform 10. The first driving assembly 411 is used to drive the first lead screw to rotate, thereby driving the first moving seat 413 and the plurality of first adsorption heads 43 to move along the length direction of the platform 40.

[0061] In one embodiment, the first drive component 411 is a motor. The first lead screw and the first movable seat 413 are connected by a threaded transmission, so that when the first lead screw rotates, it drives the first movable seat 413 to move along the length direction of the platform 40. Multiple first adsorption heads 43 are mounted on the first movable seat 413, so that when the first movable seat 413 moves, it drives the multiple first adsorption heads 43 to move, thereby adjusting the position of the multiple first adsorption heads 43 to adsorb PCB boards 70 of different sizes.

[0062] Please see Figure 6 and Figure 7 The second Y-axis moving module 42 includes a second drive assembly 421, a second lead screw 422, and a second moving seat 423. The second drive assembly 421 is connected to the second lead screw 422, and the second lead screw 422 is connected to the second moving seat 423 in a transmission manner. A plurality of second adsorption heads 44 are disposed on the side of the second moving seat 423 away from the fixed platform 10. The second drive assembly 421 is used to drive the second lead screw 422 to rotate, thereby driving the second moving seat 423 and the plurality of second adsorption heads 44 to move along the width direction of the platform 40.

[0063] In one embodiment, the second drive assembly 421 is a motor. The second lead screw 422 and the second movable seat 423 are connected by a threaded transmission, so that when the second lead screw 422 rotates, it drives the second movable seat 423 to move along the width direction of the platform 40. Multiple second adsorption heads 44 are mounted on the first movable seat 413, so that when the second movable seat 423 moves, it drives the multiple second adsorption heads 44 to move, thereby adjusting the position of the multiple second adsorption heads 44 to adsorb PCB boards 70 of different sizes.

[0064] Further, please refer to Figure 6 and Figure 7 There are two second Y-axis moving modules 42. The platform 40 is also equipped with a synchronous belt assembly 46. The synchronous belt assembly 46 connects two adjacent second lead screws 422. The synchronous belt assembly 46 includes a driving pulley 460, a driven pulley 461 and a synchronous belt body 462. The driving pulley 460 is connected to one of the second lead screws 422, and the driven pulley 461 is connected to the other second lead screw 422. The synchronous belt body 462 is sleeved on the driving pulley 460 and the driven pulley 461 so that the two adjacent second lead screws 422 rotate synchronously.

[0065] In this invention, two second Y-axis moving modules 42 move synchronously, allowing multiple second adsorption heads 44 on the two second Y-axis moving modules 42 to adjust their positions synchronously, thereby adsorbing PCB boards 70 of different sizes. This invention uses a synchronous belt assembly 46 to link the two second Y-axis moving modules 42, improving the efficiency of adjusting the positions of the multiple second adsorption heads 44.

[0066] To make the first adsorption head 43, the second adsorption head 44, and the third adsorption head 45 visible on the platform 40, please refer to [link to relevant documentation]. Figure 4 , Figure 6 and Figure 7 A limiting plate 47 is installed on the upper surface of the platform 40. The limiting plate 47 is provided with a plurality of first limiting holes 471 and a plurality of second limiting holes 472. The plurality of first limiting holes 471 extend along the length direction of the platform 40, and a plurality of first suction heads 43 are correspondingly provided in the plurality of first limiting holes 471 to move in the plurality of first limiting holes 471. The plurality of second limiting holes 472 extend along the width direction of the platform 40, and a plurality of second suction heads 44 are correspondingly provided in the plurality of second limiting holes 472 to move in the plurality of second limiting holes 472. The edge of the limiting plate 47 is provided with a plurality of third limiting holes 473, and a plurality of third suction heads 45 are provided in the third limiting holes 473.

[0067] The first adsorption head 43 protrudes from the platform 40 through the first limiting hole 471, thereby adsorbing the PCB board 70; similarly, the second adsorption head 44 protrudes from the platform 40 through the second limiting hole 472, and the third adsorption head 45 protrudes from the platform 40 through the third limiting hole 473. Further, the first limiting hole 471 can be used to limit the moving direction and range of the first adsorption head 43; the second can be used to limit the moving direction and range of the third adsorption head 45. The shapes of the first limiting hole 471 and the second limiting hole 472 can be elongated, square, or elliptical.

[0068] To ensure the smooth movement of the first movable seat 413 and the second movable seat 423, thereby driving the multiple first suction heads 43 and the multiple second suction heads 44 to move smoothly, please refer to [link to relevant documentation]. Figure 6 and Figure 7 The platform 40 is also equipped with at least two first guide rails 48, which are slidably connected to the first movable seat 413; the platform 40 is also equipped with multiple second guide rails 49, which are slidably connected to the second movable seat 423.

[0069] The number of first lead screws and first movable seats 413 is set to one each, with the first movable seats 413 moving on the first lead screw. There can be two first guide rails 48, which are set on both sides of the first lead screw. The first movable seats 413 are slidably connected to the two first guide rails 48, so that they can move smoothly on the two first guide rails 48, thereby driving the multiple first suction heads 43 to move smoothly, reducing the shaking of the multiple first suction heads 43, which would cause PCB shaking and reduced printing effect.

[0070] Please see Figure 6The number of second lead screws 422 can be multiple, and the second movable seat 423 spans the multiple second lead screws 422 and is connected to the multiple second lead screws 422 in a transmission manner; the number of second guide rails 49 is set according to the number of second lead screws 422, so that the second movable seat 423 can move smoothly on the multiple second guide rails 49, and it is convenient to install multiple second suction heads 44 onto the second movable seat 423.

The platform 40 is connected to the second movable body 221 so that the movement of the second movable body 221 drives the platform 40 to move. The first Y-axis moving module 22 drives the platform 40 to move back and forth to adjust the position of the PCB board 70.

[0074] Please see Figure 1 , Figure 2 , Figure 3 and Figure 8 The character printer 100 also includes an ink suction assembly 50, which is disposed on the fixed platform 10 and located on one side of the platform 40.

[0076] Specifically, please refer to Figure 2 , Figure 8 and Figure 9 The ink-absorbing body 51 includes multiple suction nozzles 53, an ink-absorbing cartridge 54, and multiple guide fluids 55. The opening of the ink-absorbing cartridge 54 faces the first X-axis moving module 21. The multiple suction nozzles 53 and multiple guide fluids 55 are arranged alternately in the ink-absorbing cartridge 54. The suction nozzles 53 of the ink-absorbing body 51 can draw ink from the print head of the printing module, thereby preventing excessive ink residue on the print head of the printing module. This ensures that the image quality and accuracy printed on the PCB board 70 are improved when the printing module runs again.

[0077] To store the temporarily extracted waste ink, please refer to [link / reference]. Figure 9 The ink cartridge 54 is provided with a flow channel 56. The guide fluid 55 includes multiple partitions 551, and there are guide grooves 552 between the multiple partitions 551. The guide grooves 552 are connected to the flow channel 56. The ink droplets from the print head of the printing module fall into the guide fluid 55 and can flow through the guide grooves 552 and enter the flow channel 56, where they can be temporarily stored.

[0078] The ink suction nozzle 53 of the ink suction body 51 draws ink from the print head of the printing module, and the ink directly enters the flow channel 56, where it can be temporarily stored.

[0079] In order to guide the sucked waste ink to the ink recovery assembly 60, a connecting port 57 is installed at the bottom of the ink suction box 54. One end of the connecting port 57 is connected to the flow channel 56, and the other end of the connecting port 57 is used to connect to the ink collection box 61. The waste ink in the flow channel 56 can flow into the ink collection box 61 through the connecting port 57, and the ink collection box 61 collects the waste ink.

[0080] To drive the ink-absorbing body 51 to move, specifically, please refer to... Figure 2 and Figure 8 The drive module 52 includes a third drive component 520, a third guide rail 521, a third moving seat 522 and a positioning seat 523. The ink-absorbing body 51 is mounted on the third moving seat 522, the third moving seat 522 is movably mounted on the third guide rail 521, the third guide rail 521 and the third drive component 520 are mounted on the positioning seat 523, and the positioning seat 523 is mounted on the fixed platform 10.

[0081] The third drive assembly 520 is used to drive the third moving base 522 to move on the third guide rail 521, thereby driving the ink-absorbing body 51 to move along the width direction of the platform 40 on the third guide rail 521.

[0082] The ink-absorbing body 51 is mounted on the third movable seat 522 of the drive module 52. The drive module 52 drives the third movable seat 522 to move on the third guide rail 521, thereby driving the ink-absorbing body 51 to move along the width direction of the platform 40 at the side of the platform 40. When the printing module moves to the side of the platform 40, the ink-absorbing assembly 50 can clean the print head of the printing module.

[0083] Please see Figure 3 and Figure 4 The character printer 100 also includes a recycle ink assembly 60, which is located on the fixed platform 10 and below the ink suction assembly 50. The recycle ink assembly 60 includes an ink collection box 61, a vacuum generator 62, and an ink supply system 63. The ink collection box 61 is installed on the fixed platform 10 and located below the ink suction assembly 50. The ink collection box 61 is connected to the connecting pipe port 57. The vacuum generator 62 is located below the ink collection box 61 and is connected to the ink collection box 61. The ink supply system 63 is located below the ink collection box 61, is connected to the ink collection box 61, and is connected to the printhead assembly of the printing module.

[0084] A support frame is installed under the fixed platform 10. The ink supply system 63 is mounted on the support frame and is connected to the ink collection box 61 and the ink suction assembly 50. The ink supply system 63 can adopt the structure of an existing ink supply system 63, which will not be described in detail here. The ink supply system 63 is used to connect to the printhead assembly of the printing module to supply ink to the printhead assembly; at the same time, the ink supply system 63 is also connected to the ink suction assembly 50 and the ink collection box 61 to clean the suction nozzle 53 of the ink suction assembly 50 and recover waste ink.

[0085] Since the ink absorption assembly 50, the ink collection box 61, and the ink supply system 63 are arranged sequentially from top to bottom along the height direction of the fixed platform 10, it not only facilitates the smooth flow of waste ink from the ink absorption assembly 50 into the ink supply system 63, but also effectively utilizes the space of the fixed platform 10, avoiding clutter and disorder.

[0086] The above are merely exemplary embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the technical concept of this utility model and the contents of the specification and drawings of this utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
