Description

Technical Field

[0001] This invention relates to the field of circuit board printing, and more specifically to an automatic printer for flexible circuits. Background Technology

[0002] With the rapid development of technology, the demand for thinner, lighter, more flexible, and customized electronic products is increasing, which places higher demands on the manufacturing technology of electronic circuits. Traditional rigid circuit boards can no longer meet these emerging demands, while flexible circuit boards (FPCs), with their advantages of flexibility, thinness, and adaptability, are gradually becoming an important development direction for the electronics manufacturing industry.

[0003] Chinese patent document CN114173481A discloses a process including a worktable, Y-shaped moving beams slidably connected to both ends of the top of the worktable, X-shaped moving beams on top of the Y-shaped moving beams, a support plate slidably connected to one end of the X-shaped moving beams, a moving plate slidably connected to one end of the support plate, and a Z-axis motion mechanism and other components between the support plate and the moving plate. While this process can print circuit boards, FPCs are generally not vacuum-packed at the factory, making them prone to absorbing moisture from the air during transportation and storage. Without preheating, this moisture will quickly vaporize into water vapor under the high temperature impact of reflow soldering, potentially causing defects such as FPC delamination and blistering. The document lacks corresponding pretreatment measures for FPCs, and the disclosed document does not allow for real-time station switching during FPC printing; disassembly and reloading are required after processing, which is time-consuming, labor-intensive, and inefficient. Furthermore, it lacks corresponding post-processing curing or drying measures, failing to meet practical application requirements.

[0004] Therefore, there is a need for an automatic printer with flexible circuitry designed to address the aforementioned problems. Summary of the Invention

A printing drive mechanism is mounted on a support platform, the printing drive mechanism including a print head for printing, the print head being movably mounted above the support platform.

[0007] As a further embodiment of the present invention, the workstation switching mechanism further includes a third support plate for guiding the first tooling table to descend. A plurality of guide cylinders are fixedly connected to the third support plate, and a plurality of guide columns are fixedly connected to the first support plate. The guide columns are adapted to slide on the guide cylinders and the third support plate, and a limit plate is fixedly connected to one end of the guide column.

[0008] As a further embodiment of the present invention, the workstation switching mechanism further includes a pulley for guiding the movement of the first tooling table and the second tooling table. The pulley is rotatably mounted on the worktable and is connected to the pulley by a synchronous belt drive. One side of the third support plate is fixedly connected to the synchronous belt through a second synchronous belt connecting block. The second tooling table is fixedly connected to the second support plate, and the second support plate is fixedly connected to the synchronous belt through a first synchronous belt connecting block.

[0009] As a further embodiment of the present invention, the workstation switching mechanism further includes a linear slider and a linear lead screw for driving the first workbench and the second workbench to switch positions. The second support plate is fixedly connected to the linear slider by an L-shaped fixing plate. The linear slider is limited and slidably connected to a fixed seat. The fixed seat is fixedly installed on the outside of the workbench. The linear lead screw is rotatably connected to the fixed seat, and the linear slider is threadedly connected to the linear lead screw. The linear lead screw is fixedly connected to the output shaft of a motor, and the motor is fixedly installed on the outside of the fixed seat.

[0010] As a further embodiment of the present invention, the workstation switching mechanism further includes a fourth dovetail slider and a second dovetail slider for guiding sliding connection. The second dovetail slider is fixedly connected to the third support plate. The slide table mounting base is provided with a first dovetail slider that is adapted to and slidably connected to the second dovetail slider. The fourth dovetail slider is fixedly connected to the second support plate. The worktable is provided with a third dovetail slider that is adapted to and slidably connected to the fourth dovetail slider.

[0011] As a further embodiment of the present invention, the preheating and curing mechanism further includes a first heating plate and a second heating plate for preheating or curing and drying treatment, wherein the second heating plate is fixedly installed inside the workbench and the first heating plate is fixedly installed on the workbench by a support frame.

Furthermore, the set station switching mechanism enables corresponding switching between the first and second tooling tables. This automated switching mode reduces reliance on manual operators and lowers labor costs. This parallel processing capability significantly reduces waiting time and improves the overall efficiency of printing production.

[0015] The preheating and curing mechanism, driven by the station switching mechanism, preheats the flexible circuit board to be processed. Preheating helps to slowly expel moisture from the flexible circuit board, preventing delamination, blistering, and other defects caused by rapid moisture vaporization during subsequent printing. Preheating also allows the flexible circuit board material to reach a certain thermal equilibrium, reducing thermal stress during subsequent processing and improving product stability and reliability. Simultaneously, it allows for drying and curing of the processed flexible circuit board. This drying and curing process enhances the bonding between the conductive material and the substrate, preventing detachment or peeling during use. This improves the durability and reliability of the flexible circuit board and allows it to better resist the erosion of environmental factors such as moisture and dust, maintaining long-term stable performance.

[0030] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0031] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0032] Example 1 See Figures 1-3 An automatic printer for flexible circuits includes a support platform 1, on which a worktable 7 for mounting flexible circuit boards is movably mounted. The worktable 7 is fixedly mounted on a movable plate 2 via a mounting plate 8, and the movable plate 2 is movably mounted on the support platform 1. The worktable 7 is provided with a first fixture 9 and a second fixture 10 for placing and mounting the circuit boards. The printer also includes: A printing drive mechanism is mounted on a support platform 1. The printing drive mechanism includes a print head 3 for printing, which is movably mounted above the support platform 1.

[0033] Furthermore, the printing drive mechanism also includes an X-moving module 4, a Z-moving module 5, and a Y-moving module 6 for linear drive. The printhead 3 is mounted on the X-moving module 4, the X-moving module 4 is mounted on the Z-moving module 5, and the movable plate 2 is mounted on the Y-moving module 6.

[0034] Preferably, when printing flexible circuit boards, the flexible circuit board is placed on the first fixture 9 and the second fixture 10 fixed on the worktable 7. The X-moving module 4 drives the print head 3 to perform printing in the X-axis direction, the Z-moving module 5 drives the print head 3 to perform printing in the Z-axis direction, and the Y-moving module 6 can drive the worktable 7 to adjust the printing position.

[0035] It should be noted that the drivers for X mobile module 4, Z mobile module 5 and Y mobile module 6 are common knowledge known to those skilled in the art, and will not be elaborated upon further in this article.

[0036] Example 2 like Figures 1-12 As shown, this embodiment, based on embodiment 1, also includes a workstation switching mechanism, which is installed on the workbench 7 and is used to drive the first tooling table 9 and the second tooling table 10 to switch workstations. The workstation switching mechanism includes a drive rod 22 and a vertical plate 24 for driving the first tooling table 9 and the second tooling table 10 to switch workstations, and a synchronous belt 41 for synchronously pulling the first tooling table 9 and the second tooling table 10 to move. The drive rod 22 is fixedly installed on one side of the first tooling table 9 through the first support plate 17. One end of the drive rod 22 is rotatably connected to a drive pulley 23. The vertical plate 24 is provided with a drive groove 25 adapted to connect the drive pulley 23.

[0037] Furthermore, the workstation switching mechanism also includes a third support plate 21 for guiding the first tooling table 9 to descend. Several guide cylinders 19 are fixedly connected to the third support plate 21, and several guide columns 18 are fixedly connected to the first support plate 17. The guide columns 18 are adapted to slide on the guide cylinders 19 and the third support plate 21, and a limit plate 20 is fixedly connected to one end of the guide column 18.

[0038] Furthermore, the workstation switching mechanism also includes a pulley 35 for guiding the movement of the first tooling table 9 and the second tooling table 10. The pulley 35 is rotatably mounted on the worktable 7, and the synchronous belt 41 is connected to the pulley 35. One side of the third support plate 21 is fixedly connected to the synchronous belt 41 through the second synchronous belt connecting block 34. The second tooling table 10 is fixedly connected to the second support plate 11, and the second support plate 11 is fixedly connected to the synchronous belt 41 through the first synchronous belt connecting block 33.

[0039] Furthermore, the workstation switching mechanism also includes a linear slider 13 and a linear lead screw 14 for driving the first workbench 9 and the second workbench 10 to switch workstations. The second support plate 11 is fixedly connected to the linear slider 13 by an L-shaped fixing plate 12. The linear slider 13 is limited and slidably connected to the fixed seat 15. The fixed seat 15 is fixedly installed on the outside of the workbench 7. The linear lead screw 14 is rotatably connected to the fixed seat 15, and the linear slider 13 is threadedly connected to the linear lead screw 14. The linear lead screw 14 is fixedly connected to the output shaft of the motor 16. The motor 16 is fixedly installed on the outside of the fixed seat 15.

[0040] Furthermore, the workstation switching mechanism also includes a fourth dovetail slider 37 and a second dovetail slider 28 for guiding sliding connection. The second dovetail slider 28 is fixedly connected to the third support plate 21. The slide table mounting base 26 is provided with a first dovetail slider 27 that is adapted to slide and connected to the second dovetail slider 28. The fourth dovetail slider 37 is fixedly connected to the second support plate 11. The worktable 7 is provided with a third dovetail slider 36 that is adapted to slide and connected to the fourth dovetail slider 37.

[0041] Preferably, in this embodiment, when the flexible circuit board at the second tooling table 10 has been printed and the flexible circuit board to be printed at the first tooling table 9 has been fixed on the worktable 7, and it is necessary to replace the flexible circuit board for printing, the output shaft of the motor 16 drives the linear lead screw 14 to rotate. With the linear slider 13 and the linear lead screw 14 threadedly connected, the second support plate 11 can drive the flexible circuit board on the second tooling table 10 to move closer to the motor 16. The second support plate 11 is limited to move on the worktable 7 by the fourth dovetail slider 37 and the third dovetail slider 36. At this time, since the synchronous belt 41 is connected to the pulley 35, and the second support plate 11 is fixedly connected to the synchronous belt 41 through the first synchronous belt connecting block 33, and the third support plate 21 is fixedly connected to the synchronous belt 41 through the second synchronous belt connecting block 34, the first tooling table 9 can be driven to move away from the motor 16 under the transmission and guidance of the synchronous belt 41, thus completing the opposite movement of the first tooling table 9 and the second tooling table 10. Correspondingly, since the drive rod 22 fixedly connected to one side of the first support plate 17 is transmitted to the drive groove 25 on the vertical plate 24 by the drive pulley 23, under the limiting drive of the drive groove 25 and the guiding action of the guide column 18 and guide cylinder 19, when the first tooling table 9 and the second tooling table 10 have both moved to the middle position of the worktable 7, due to the vertical driving limit of the drive groove 25, the first tooling table 9 drives the guide column 18 to move downward. At this time, the second tooling table 10 is in the position above the first tooling table 9, and the first tooling table 9 is in the position below the second tooling table 10. This realizes the avoidance treatment for the switching of the first tooling table 9 and the second tooling table 10, so that the first tooling table 9 can move to the processing position, while the second tooling table 10 moves to the initial position. Specifically, see Figure 8 As shown, this automated switching mode reduces reliance on human operators and lowers labor costs. This parallel processing capability significantly reduces waiting time and improves the overall efficiency of printing production.

[0042] It should be noted that the output shaft of motor 16 can be driven in both forward and reverse directions.

[0043] Example 3 like Figures 1 to 11 As shown, this embodiment, based on the above embodiment, also includes a preheating and curing mechanism, which is installed on the workbench 7 and driven by the workstation switching mechanism. It is used to preheat and dry the flexible circuit boards on the first tooling table 9 and the second tooling table 10. The preheating and curing mechanism includes a switch mounting base 30 for triggering preheating or drying and curing. The switch mounting base 30 is fixedly connected to the upright plate 24 through the slide mounting base 26. A first proximity switch 31 and a second proximity switch 32 are provided on the switch mounting base 30.

[0044] Furthermore, the preheating and curing mechanism also includes a first heating plate 39 and a second heating plate 40 for preheating or curing and drying. The second heating plate 40 is fixedly installed inside the workbench 7, and the first heating plate 39 is fixedly installed on the workbench 7 via a support frame 38.

[0045] Furthermore, the preheating and curing mechanism also includes a proximity plate 29 for triggering preheating and curing during workstation switching. The proximity plate 29 is fixedly connected to the second dovetail slider 28 and is movably connected to the outside of the first proximity switch 31 and the second proximity switch 32.

[0046] Preferably, in this embodiment, based on the workstation switching, since the third support plate 21 is slidably connected to the first dovetail slider 27 via the second dovetail slider 28, whenever the third support plate 21 switches workstations, it correspondingly drives the proximity plate 29 to move. Whenever the first fixture table 9 and the second fixture table 10 are at the overlapping position of the workstation switching, since the proximity plate 29 first passes the first proximity switch 31 and then reaches the second proximity switch 32, the first fixture table 9 is located below the second fixture table 10. The first fixture table 9 contains the flexible circuit board to be printed, while the second fixture table 10 contains the flexible circuit board to be printed. The flexible circuit board on table 10 has already been printed. At this time, the second heating plate 40 is located above the first tooling table 9. The second heating plate 40 preheats the flexible circuit board on the first tooling table 9. This is mainly because the flexible circuit board is prone to absorbing moisture from the air during transportation and storage. Preheating can help to slowly remove this moisture, avoiding delamination, blistering and other defects caused by rapid vaporization of moisture during subsequent printing. At the same time, preheating can bring the flexible circuit board material to a certain thermal equilibrium state, reducing thermal stress during subsequent processing, thereby improving the stability and reliability of the product. A first heating plate 39 is provided above the corresponding second tooling table 10 to perform heat-induced drying and curing treatment on the flexible circuit board on the second tooling table 10. The drying and curing treatment helps to enhance the bonding force between the conductive material and the substrate, and prevents detachment or peeling during use. This improves the durability and reliability of the flexible circuit board. At the same time, through the drying and curing treatment, the flexible circuit board can better resist the erosion of environmental factors such as moisture and dust, and maintain long-term stable performance.

[0047] Conversely, when the flexible circuit board on the first fixture 9 is finished and the flexible circuit board to be processed on the second fixture 10 is fixed, when the first fixture 9 moves back to the initial position for station switching, it first passes the second proximity switch 32 and then reaches the first proximity switch 31. At this time, the second heating plate 40 can perform heat drying and curing treatment on the flexible circuit board that has been finished on the first fixture 9, while the first heating plate 39 preheats the flexible circuit board to be processed on the second fixture 10, thus forming a cycle and significantly improving the printing and processing efficiency of flexible circuit boards.

[0048] It should be noted that the preheating or drying and curing processes of the first heating plate 39 and the second heating plate 40 are controlled by the movement of the approach plate 29.

[0049] It should also be noted that the preheating stage is usually to bring the flexible circuit board to an initial temperature suitable for further processing. The power of this stage may be relatively low to avoid thermal stress or damage to the circuit board due to sudden heating. Meanwhile, the heating and drying stage is to remove moisture or solvents from the circuit board to achieve the required degree of dryness. The power of this stage may be relatively high to ensure sufficient heat input to achieve the drying effect.

[0050] It should be noted that the components in this application are all general standard parts or parts known to those skilled in the art, which effectively solve the technical problems raised in the background art.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
