Description

Technical Field

[0001] This invention relates to the field of circuit board manufacturing technology, and in particular to a flexible board solder resist processing system and processing method. Background Technology

[0002] Solder resist for flexible printed circuit boards (FPCs) refers to the application of specialized flexible liquid photosensitive solder resist ink, sprayed onto the surface of the FPC to form a protective layer distinct from traditional cover films. Its functions include: insulation to prevent short circuits caused by solder bridges; protection of copper traces against oxidation, moisture, and chemicals; precise exposure of SMT (Surface Mount Technology) pads and gold fingers; and surface insulation to prevent leakage current from adjacent traces.

[0003] In traditional technology, flexible circuit board solder resist processing typically employs a single-sided independent operation mode. This involves screen printing on one side of the flexible circuit board in a cleanroom, followed by pre-baking, exposure, and development. The developed board then undergoes pre-curing and pretreatment (such as acid pickling) before exiting the cleanroom. The process is repeated on the second side, involving screen printing, pre-baking, exposure, and development, before final curing. This traditional solder resist processing method is lengthy, consumes significant manpower and materials, has a long turnaround time, and results in low production efficiency. Summary of the Invention

[0004] This invention provides a flexible plate resist welding processing system and method, which can solve the problems of long execution process, large consumption of manpower and materials, long final output time and low production efficiency in traditional resist welding processing mode.

[0005] To achieve the above objectives, the present invention provides a flexible plate solder resist processing system, comprising: The first printing and baking line includes a first printing machine, a first robotic arm, a first settling machine, a first baking oven, a first buffer machine, and a film peeling machine arranged sequentially in the transverse direction; The second printing and baking line includes a second printing machine, a transfer table, a second settling machine, a second robotic arm, a second baking oven, a third robotic arm, and a second buffer machine arranged sequentially in the transverse direction; The second return conveyor line includes a return conveyor belt arranged laterally between the first printing baking line and the second printing baking line, and a corner conveyor connecting the starting end of the return conveyor belt and the second buffer machine; An exposure device includes a double-sided exposure machine with a flexible plate flipping function, a fourth robotic arm and a fifth robotic arm respectively arranged on both sides of the double-sided exposure machine, a first clapping device connected to the film-tearing machine, and a second clapping device connected to the end of the return conveyor belt. The fourth robotic arm is arranged corresponding to the first clapping device, and the fifth robotic arm is arranged corresponding to the second clapping device. The unloading equipment includes a first storage bin and a second storage bin respectively located on both sides of the double-sided exposure machine, a rotating material frame corresponding to and cooperating with the second storage bin and the fifth robotic arm, and a sixth robotic arm corresponding to and cooperating with the rotating material frame, the second printing machine, and the transfer table. The first storage bin corresponds to and cooperates with the fourth robotic arm.

[0006] Furthermore, this invention also proposes a flexible plate solder resist processing method, applied to the flexible plate solder resist processing system described above; the processing method includes: The first side of the flexible board is printed by the first printing press, and the printed flexible board is transferred to the first settling machine by the first robotic arm for settling. Then the settling flexible board is sent to the first baking oven for pre-baking. The pre-baked flexible board is then sent to the first buffer machine for buffering. The first buffer machine sends the flexible board to the film peeling machine to remove the protective film on the second side of the flexible board. The film-peeling machine transports the flexographic board after film peeling to the first plate-pressing device for sorting and arranging. Then, the fourth robot arm moves the arranged flexographic board to one side of the exposure table of the double-sided exposure machine for exposure of the first side of the flexographic board. If the first side of the flexographic board fails the exposure test, the fourth robot arm moves the flexographic board that fails the exposure test to the first storage bin for storage and unloading. When the first side of the flexographic board passes the exposure test, the double-sided exposure machine flips the flexographic board so that the second side of the flexographic board faces upward, and the fifth robot arm moves the flexographic board to the rotating material frame. The first exposed flexographic plate is rotated by a rotating material frame to adjust its orientation. Then, the rotated flexographic plate is transferred to the second printing press by the sixth robot arm to print the second side of the flexographic plate. The printed flexographic plate is then transferred to the transfer table by the sixth robot arm to the second settling machine for settling. The settling flexographic plate is then transferred to the second baking oven by the second robot arm for baking. The baked flexographic plate is then transferred to the second buffer machine for buffering by the third robot arm. The second buffer machine then transports the flexographic plate to the corner conveyor to the return conveyor belt. The flexographic boards, which have undergone two baking processes, are conveyed to the second plate-setting device via a return conveyor belt for sorting and arranging. Then, the fifth robotic arm moves the arranged flexographic boards to the other side of the exposure table of the double-sided exposure machine for exposure of the second side of the flexographic boards. If the second side of the flexographic board fails the exposure test, the fifth robotic arm moves the defective flexographic board to the defective product bin of the second storage silo for storage and unloading. If the second side of the flexographic board passes the exposure test, the fifth robotic arm moves the passable flexographic board to the good product bin of the second storage silo for storage and unloading.

[0007] The beneficial effects of the technical solution provided by this invention include: By setting up a double-sided exposure machine with a flexible plate flipping function, the fourth robotic arm and the first clapping device are connected to the film-peeling machine of the first printing and baking line, and the fifth robotic arm and the second clapping device are connected to the return conveyor belt of the second return conveyor line. The fifth robotic arm, the rotating material frame, and the sixth robotic arm are connected to the second printing machine of the second printing and baking line. This allows for printing, baking, and exposure of the first side of the flexible plate, followed immediately by printing, baking, and exposure of the second side. The flexible plate can be exposed on both sides before being shipped out, and then developed and cured. Compared to the traditional single-sided independent operation mode used in flexible plate solder resist processing, this invention simplifies one shipping process and eliminates one developing process, one curing process, and one pickling process, reducing manpower and material consumption in these three processes, improving production efficiency, shortening product cycle time, and reducing production costs.

Detailed Implementation

[0011] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0012] like Figure 1 As shown, the present invention provides a flexible plate solder resist processing system 10, including a first printing and baking line 12, a second printing and baking line 14 arranged side by side with the first printing and baking line 12, a second reflow conveyor line 16 arranged side by side with the first printing and baking line 12 and the second printing and baking line 14, and an exposure device 18 and a feeding device 19 connected to the first printing and baking line 12 and the second reflow conveyor line 16.

[0013] The first printing and baking line 12 can print and bake the first side (e.g., side A) of the flexible plate, and the second printing and baking line 14 can print and bake the second side (e.g., side B) of the flexible plate. The second return conveyor line 16 can return the flexible plate with the second side printed and baked. The exposure equipment 18 can expose the first side of the flexible plate printed and baked by the first printing and baking line 12 and expose the second side of the flexible plate printed and baked by the second printing and baking line 14. The unloading equipment 19 can unload the flexible plate with both sides exposed to prepare it for developing and curing.

[0014] Furthermore, by arranging the first printing and baking line 12, the second printing and baking line 14, and the second reflow conveyor line 16 side by side in the transverse direction, and by placing the exposure equipment 18 and the unloading equipment 19 at the same end of the first printing and baking line 12, the second printing and baking line 14, and the second reflow conveyor line 16, not only can the entire production line be made compact, but also space can be saved and product turnover efficiency can be improved. Moreover, the flexible board solder resist processing system 10 is set up in a cleanroom. After the flexible board has undergone pretreatment (including line etching, surface treatment, etc.), the flexible board can be transferred to the flexible board solder resist processing system 10 in the cleanroom for double-sided printing and double-sided exposure processing. Then, the flexible board is transferred outside the cleanroom for developing and curing processing.

[0015] Specifically, the first printing and baking line 12 may include a first printing machine 100, a first robotic arm 200, a first settling machine 300, a first baking oven 400, a first buffer machine 500, and a film peeling machine 600 arranged sequentially in the transverse direction. The first printing machine 100 can print ink on the first side (e.g., side A) of the flexible board. Then, the first robotic arm 200 can transfer the printed flexible board to the first settling machine 300 for settling. Then, the first settling machine 300 can convey it to the first baking oven 400 for pre-baking. Then, the first baking oven 400 can convey the baked flexible board to the first buffer machine 500 for buffering to avoid material stacking. Then, the first buffer machine 500 can convey the flexible board to the film peeling machine 600 to peel off the protective film on the second side of the flexible board (if the second side of the flexible board has a protective film), or directly convey it to the exposure equipment 18 to prepare for exposure of side A of the flexible board.

[0016] Furthermore, the second printing and baking line 14 may include a second printing machine 700, a transfer table 800, a second settling machine 900, a second robot arm 1000, a second baking oven 1100, a third robot arm 1200, and a second buffer machine 1300 arranged sequentially in the horizontal direction. The second printing press 700 can print ink on the second side (e.g., side B) of the flexographic plate. The printed flexographic plate can then be transferred to the transfer table 800. The transfer table 800 can then transport the flexographic plate printed on side B to the second settling machine 900 for settling. The second robot 1000 can then transfer the flexographic plate set in the second settling machine 900 to the second baking oven 1100 for pre-baking. The third robot 1200 can then transfer the flexographic plate baked in the second baking oven 1100 to the second buffer machine 1300 for buffering to avoid stacking. The flexographic plate can then be transported to the second return conveyor line 16 via the second buffer machine 1300, and then to the exposure equipment 18 via the second return conveyor line 16 for exposure of side B.

[0017] Furthermore, the second return conveyor line 16 may include a return conveyor belt 1400 arranged laterally between the first printing baking line 12 and the second printing baking line 14, and a corner conveyor 1500 connecting the starting end of the return conveyor belt 1400 and the second buffer machine 1300. The corner conveyor 1500 allows for a rotary connection between the parallel second printing baking line 14 and the return conveyor belt 1400, enabling the return conveying of the flexographic plate after secondary printing when sharing the exposure equipment 18. Moreover, to achieve the return conveying of the flexographic plate after secondary printing, the second printing machine 700 can be docked with the exposure equipment 18, facilitating the transfer of the flexographic plate exposed on side A to the second printing machine 700 for side B printing. Furthermore, the end of the return conveyor belt 1400 can be docked with the exposure equipment 18, facilitating side B exposure of the returned flexographic plate after side B printing and baking.

[0018] Furthermore, the exposure equipment 18 may include a double-sided exposure machine 1600 with a flexible plate flipping function, a fourth robotic arm 1700 and a fifth robotic arm 1800 respectively arranged on both sides of the double-sided exposure machine 1600, a first clapping device 1900 connected to the film tearing machine 600, and a second clapping device 2000 connected to the end of the return conveyor belt 1400. The fourth robotic arm 1700 is arranged in correspondence with the first clapping device 1900, and the fifth robotic arm 1800 is arranged in correspondence with the second clapping device 2000. The first plate-tapping device 1900 receives the flexographic board with A-side printing and baking from the film-tearing machine 600, and arranges and lays out the flexographic board (e.g., arranging two flexographic boards together). The fourth robot arm 1700 can transfer the arranged flexographic board to the first exposure position 1622 of the double-sided exposure machine 1600 for A-side exposure. Then, the double-sided exposure machine 1600 can flip the flexographic board exposed on A-side so that its B-side is facing up. The fifth robot arm 1800 can then transfer the B-side-facing flexographic board to the second printing and baking line 14 for B-side printing and baking. The second return conveyor line 16 can then transport the B-side-printed and baked flexographic board to the second plate-tapping device 2000 for arranging and laying out the flexographic board (e.g., arranging two flexographic boards together). The fifth robot arm 1800 can then transfer the arranged flexographic board to the second exposure position 1624 of the double-sided exposure machine 1600 for B-side exposure.

[0019] Furthermore, the unloading device 19 may include a first storage bin 2100 and a second storage bin 2200 respectively located on both sides of the double-sided exposure machine 1600, a rotating material frame 2300 corresponding to and cooperating with the second storage bin 2200 and the fifth robot arm 1800, and a sixth robot arm 2400 corresponding to and cooperating with the rotating material frame 2300, the second printing machine 700, and the transfer table. The first storage bin 2100 is corresponding to and cooperating with the fourth robot arm 1700. After the A side of the flexographic plate is exposed at the first exposure position 1622 of the double-sided exposure machine 1600, if the exposure is unqualified, the unqualified flexographic plate can be transferred to the first storage bin 2100 for storage by the fourth robot arm 1700; otherwise, the flexographic plate that has passed the exposure can be flipped by the double-sided exposure machine 1600 so that the B side is facing up, and then the flipped flexographic plate can be transferred to the rotating material frame 2300 by the fifth robot arm 1800. The flexographic plate is rotated by the rotating material frame 2300 to make the flexographic plate in the required position, and then the flexographic plate can be transferred from the rotating material frame 2300 to the second printing machine 700 for printing by the sixth robot arm 2400.

[0020] By setting up a double-sided exposure machine 1600 with a flexible plate flipping function, and connecting it to the film-peeling machine 600 of the first printing and baking line 12 via a fourth robot 1700 and a first tapping device 1900, and connecting it to the return conveyor belt 1400 of the second return conveyor line 16 via a fifth robot 1800 and a second tapping device 2000, and connecting it to the second printing machine 700 of the second printing and baking line 14 via a fifth robot 1800, a rotating material frame 2300, and a sixth robot 2400, the second side of the flexible plate can be printed, baked, and exposed immediately after the first side is exposed. The flexible plate can be exposed on both sides before being shipped out, and then developed and cured. Compared to the traditional single-sided independent operation mode used in flexible plate solder resist processing, this invention simplifies one shipping process and eliminates one developing process, one curing process, and one acid washing process, reducing the manpower and material consumption of these three processes, improving production efficiency, shortening the product cycle, and reducing production costs.

[0021] Furthermore, the first printing press 100 is used to print ink on side A of the flexible plate, and the second printing press 700 is used to print ink on side B of the flexible plate. For example... Figure 2 As shown, both the first settling machine 300 and the second settling machine 900 can enter and exit the interior of the settling machine through L-shaped shelves. Each shelf is individually timed, allowing for first-in, first-out (FIFO) operation of the flexible board. Figure 3 As shown, both the first buffer machine 500 and the second buffer machine 1300 use rollers to feed the flexible boards into and out of the buffer machines, and they enter and exit the buffer machines through L-shaped shelves to prevent subsequent stacking of materials and boards. The film-peeling machine 600 can automatically peel off the protective film on the reverse side (e.g., side B) of the flexible board, and can also be set to a straight-through mode to allow flexible boards without film to pass directly through. In addition, the first printing machine 100, the second printing machine 700, the first settling machine 300, the second settling machine 900, the first buffer machine 500, the second buffer machine 1300, and the film-peeling machine 600 are all existing equipment and will not be described in detail here.

[0022] Furthermore, the first baking oven 400 is a single-layer horizontal baking oven, and the second baking oven 1100 is a vertically suspended tunnel oven. Since the first baking oven 400 only bakes the flexographic board printed on side A, the flexographic board printed on side A can be horizontally laid on a conveyor belt (with side A facing upwards) for transport and baking. However, when baking the flexographic board in the second baking oven 1100, since both sides A and B are printed, to avoid affecting the printed surfaces, the flexographic board can be vertically suspended for double-sided baking. Moreover, the single-layer horizontal baking oven can be a standard single-layer horizontal IR (Infrared) baking oven.

[0023] Moreover, such as Figure 4As shown, the vertically suspended tunnel oven may include a main oven body 1110, a baking clamp assembly disposed within the main oven body 1110, and a switching clamp device 1130 disposed on the main oven body 1110 and correspondingly cooperating with the baking clamp assembly. The baking clamp assembly can move the suspended clamp 1120, causing the suspended clamp 1120 to move to the switching clamp device 1130; and the switching clamp device 1130 can automatically open the suspended clamp 1120, facilitating the movement of the flexible board to be baked to the opened suspended clamp 1120, so that the suspended clamp 1120 automatically clamps the flexible board conveyed by the second robot arm 1000, and the baking clamp assembly can move the suspended clamp 1120 holding the flexible board into the main oven body 1110 for baking.

[0024] Furthermore, such as Figures 4 to 6 As shown, the main furnace body 1110 is provided with a baking chamber 1112, through which the flexible board can be baked. Furthermore, the baking fixture assembly may include a fixture circulation conveying mechanism located at the top of the baking chamber 1112, and multiple suspended fixtures 1120 located on the fixture circulation conveying mechanism. A switching clamp device 1130 may be located on the top wall of the inlet / outlet 1916 of the baking chamber 1112, corresponding to and cooperating with the suspended fixtures 1120, for opening the suspended fixtures 1120. Multiple suspended clamps 1120 can be circulated and transported by the clamp circulation conveying mechanism, so that the suspended clamps 1120 are moved sequentially to the inlet / outlet 1916 of the baking chamber 1112. After the suspended clamps 1120 moved to the inlet / outlet 1916 are opened by the switch clamping device 1130, the flexible board can be moved to the suspended clamps 1120 to clamp the flexible board. Then, the suspended clamps 1120 and the clamped flexible board can be transported back to the baking chamber 1112 by the clamp circulation conveying mechanism to facilitate the baking of the flexible board.

[0025] Furthermore, the fixture circulating conveyor mechanism can be configured as a chain conveyor mechanism. For example... Figures 4 to 5As shown, the suspension clamp 1120 may include a lifting rod 1122 suspended on the conveyor chain of the chain conveyor mechanism, and an elastic clamp 1124 disposed on one side of the bottom of the lifting rod 1122. Moreover, the elastic clamp 1124 may include a chuck 11242 elastically hinged to one side of the bottom of the lifting rod 1122 by a spring 11246, and a hook 11244 extending below the bottom of the chuck 11242. Under normal conditions, the hook 11244 of the elastic clamp 1124 is closed between the hook 11244 and the side of the lifting rod 1122 under the elastic force of the spring 11246. When the switching clamp device 1130 squeezes the clamp 11242 of the elastic clamp 1124, the hook 11244 of the elastic clamp 1124 overcomes the elastic force of the spring 11246 and moves the hook 11244 away from the side of the lifting rod 1122, so that the hook 11244 opens, making it easier to clamp the flexible plate between the hook 11244 and the side of the lifting rod 1122.

[0026] like Figures 5 to 6 As shown, the switching clamping device 1130 may include a mounting base 1132 for installation on the top wall of the inlet / outlet 1916 of the baking chamber 1112, and a positioning clamp 1134 and a pushing clamp 1136 disposed opposite to the bottom of the mounting base 1132. A clamping gap is formed between the positioning clamp 1134 and the pushing clamp 1136, which can clamp and squeeze the suspension clamp 1120 for clamping the flexible board, so that the suspension clamp 1120 automatically opens to automatically clamp the flexible board to be baked transferred by the second robot arm 1000.

[0027] Furthermore, the positioning clamp 1134 may include a first telescopic drive member 11342 suspended on one side of the bottom of the mounting base 1132, and a positioning plate 11344 connected to the drive end of the first telescopic drive member 11342. Moreover, the pushing clamp 1136 may include a second telescopic drive member 11362 suspended on the other side of the bottom of the mounting base 1132, a drive connecting plate 11364 disposed at the drive end of the second telescopic drive member 11362, a rotating linkage structure 11366 hinged to the drive connecting plate 11364 and the bottom of the mounting base 1132, and a pushing plate structure 11368 disposed at the end of the rotating linkage structure 11366. Furthermore, the pushing plate structure 11368 and the positioning plate 11344 are arranged opposite to each other, forming a clamping gap between them for clamping the suspension clamp 1120 from both sides; the positioning plate 11344 is used to correspond to one side of the lifting rod 1122 of the suspension clamp 1120, and the pushing plate structure 11368 is used to correspond to the clamp 11242 of the elastic clamp 1124 installed on the other side of the suspension clamp 1120.

[0028] The switch clamp device 1130 can be suspended and installed on the top wall of the inlet / outlet 1916 of the baking chamber 1112 via the mounting base 1132. When the suspension clamp 1120 in the baking chamber 1112 moves to the clamping gap between the positioning clamp 1134 and the pushing clamp 1136 of the switch clamp device 1130, the first telescopic drive member 11342 of the positioning clamp 1134 can drive the positioning plate 11344 to move closer to the lifting rod 1122 on one side of the suspension clamp 1120 and press the lifting rod 1122 against it, thus allowing the suspension clamp 1120 to be lifted from one side. The side positioning prevents wobbling. Simultaneously, the second telescopic drive member 11362 of the pushing clamp 1136 drives the drive connecting plate 11364 to move closer to the suspension clamp 1120. This causes the drive connecting plate 11364 to rotate the rotating linkage structure 11366, which in turn drives the pushing plate structure 11368 closer to the elastic clamp 1124 on the other side of the suspension clamp 1120. The clamping head 11242 of the elastic clamp 1124 gradually tightens, causing the clamping hook 11244 of the elastic clamp 1124 to open. At this point, a robotic arm or other conveying equipment can be used to move the flexible plate to be clamped to the clamping hook 11244.

[0029] Then, the second telescopic drive member 11362 of the pushing clamp 1136 can drive the drive connecting plate 11364 to move away from the suspension clamp 1120, causing the drive connecting plate 11364 to drive the rotating linkage structure 11366 to rotate in the opposite direction. This allows the rotating linkage structure 11366 to drive the push plate structure 11368 away from the elastic clamp 1124 on the other side of the suspension clamp 1120, gradually loosening the clamp 11242 of the elastic clamp 1124, causing the clamp hook 11244 of the elastic clamp 1124 to close again to hold the flexible plate located at the clamp hook 11244. At this time, the first telescopic drive member 11342 of the positioning clamp 1134 can drive the positioning plate 11344 to move away from the lifting rod 1122 on the side away from the suspension clamp 1120, gradually separating it from the lifting rod 1122. This causes the positioning fixture 1134 and the pushing fixture 1136 to release their clamping and positioning of the suspension fixture 1120 and the flexible plate it holds, so that the suspension fixture 1120 moves into the baking chamber 1112 under the drive of the fixture circulation conveying mechanism in the baking chamber 1112.

[0030] In this way, the switching clamping device 1130 can automatically open and close the suspension clamp 1120 in the baking chamber 1112, automatically clamping and releasing the flexible board to be baked. Compared with the traditional technology of manually opening the suspension clamp 1120, the switching clamping device 1130 provided by this invention can greatly improve the efficiency of clamping the flexible board, improve the efficiency of baking the flexible board, and reduce the workload of workers.

[0031] Specifically, the mounting base 1132 may include a mounting top plate for mounting on the top wall of the inlet / outlet 1916 of the baking chamber 1112, and a mounting hanging plate on each side protruding from the bottom of the mounting top plate. The positioning clamp 1134 and the pushing clamp 1136 may be respectively mounted on the two mounting hanging plates. The two mounting hanging plates may be arranged vertically side by side, so that the two positioning clamps 1134 and the pushing clamp 1136 are horizontally corresponding and engaged. Moreover, the first telescopic drive member 11342 of the positioning clamp 1134 may be mounted on one of the mounting hanging plates, and the second telescopic drive member 11362 and the rotating linkage structure 11366 of the pushing clamp 1136 may be connected to the other mounting hanging plate. In this way, the positioning plate 11344 of the positioning clamp 1134 and the pushing plate structure 11368 of the pushing clamp 1136 may be arranged horizontally opposite each other, which facilitates positioning and squeezing opening from both sides of the suspension clamp 1120.

[0032] In addition, the mounting base 1132 may also include a limiting bracket on each side of the bottom of the mounting top plate, with the two limiting brackets located on the outer sides of the two mounting plates. The height of the limiting brackets is greater than the height of the mounting plates, thus limiting the positioning clamp 1134 and the pushing clamp 1136.

[0033] Furthermore, both the first telescopic drive member 11342 of the positioning clamp 1134 and the second telescopic drive member 11362 of the pushing clamp 1136 can include a telescopic drive cylinder arranged laterally on the mounting plate, with the drive end of the telescopic drive cylinder connected to the positioning plate 11344 or the drive connecting plate 11364. This allows the telescopic drive cylinder to directly drive the positioning plate 11344 or the drive connecting plate 11364 to extend and retract, causing the positioning plate 11344 and the drive connecting plate 11364 to approach the suspension clamp 1120 from both sides, thus achieving the positioning and opening of the suspension clamp 1120. Alternatively, the telescopic drive cylinder can be replaced with a linear motor drive module or a hydraulic drive cylinder.

[0034] Furthermore, both the first telescopic drive member 11342 and the second telescopic drive member 11362 can include a telescopic guide structure disposed laterally on the mounting plate. The telescopic guide structure is arranged side by side with the telescopic drive cylinder and is connected to the positioning plate 11344 or the drive connecting plate 11364. The telescopic guide structure can guide the positioning plate 11344 or the drive connecting plate 11364 to telescopically move, making the telescopic movement of the positioning plate 11344 or the drive connecting plate 11364 stable and reliable, and less prone to deviation.

[0035] Furthermore, the telescopic guide structure may include two telescopic guide rods that are movably mounted side-by-side on the mounting plate. The two telescopic guide rods are located on both sides of the telescopic drive cylinder, and their ends are connected to the positioning plate 11344 or the drive connecting plate 11364. By providing one telescopic guide rod on each side of the telescopic drive cylinder, the positioning plate 11344 or the drive connecting plate 11364 can be telescopically supported from both sides, ensuring stability and reliability. Moreover, to ensure smooth movement of the telescopic guide rods, two telescopic sleeves can be provided on the mounting plate, and the two telescopic guide rods can be movably fitted into the two telescopic sleeves respectively. The ends of the two telescopic guide rods can be connected to the two ends of one side of the positioning plate 11344 or the drive connecting plate 11364, respectively, while the drive end of the telescopic drive cylinder can be connected to the middle of one side of the positioning plate 11344 or the drive connecting plate 11364. Furthermore, the other side of the positioning plate 11344 corresponds to the lifting rod 1122 of the suspension clamp 1120, while the other side of the drive connecting plate 11364 is provided with a rotating linkage structure 11366. Additionally, the positioning plate 11344 may include a main body connected to the telescopic drive cylinder and the telescopic guide rod, and a flexible plate pad disposed on the abutment surface of the main body. The flexible plate pad is used to abut against the lifting rod 1122 of the suspension clamp 1120, thereby reducing the impact force on it.

[0036] Furthermore, the rotating linkage structure 11366 may include a first straight connecting rod hinged to the mounting plate, and a second curved connecting rod hinged to the end of the first straight connecting rod. The middle curved portion of the second curved connecting rod is hinged to the drive connecting plate 11364, and the end of the second curved connecting rod is connected to the push plate structure 11368. By connecting the drive connecting plate 11364 and the push plate structure 11368 through the rotating linkage structure 11366, the telescopic movement of the drive connecting plate 11364 can be converted into the rotational movement of the push plate structure 11368. This allows the push plate structure 11368 to gradually approach or move away from the clamp 11242 of the suspension clamp 1120 through rotation. This allows the clamp hook 11244 of the suspension clamp 1120 to be opened by rotational compression, enabling the push plate structure 11368 to adapt to the rotational changes of the clamp 11242 when the clamp hook 11244 is opened.

[0037] Specifically, a first hinge seat can be provided on the side of the mounting plate, one end of the first straight connecting rod can be hinged to the first hinge seat, and the other end can be hinged to one end of the second curved connecting rod; a second hinge seat can be provided on the drive connecting plate 11364, the middle curved part of the second curved connecting rod can be hinged to the second hinge seat, and its other end is fixedly connected to the side of the push plate structure 11368. By setting the second curved connecting rod to a curved shape, it is convenient to change the position of the push plate structure 11368 connected to the second curved connecting rod, so that the push plate structure 11368 can more appropriately correspond and cooperate with the suspension clamp 1120. In this embodiment, the second curved connecting rod can be set as an L-shaped connecting rod.

[0038] Furthermore, not only can one rotating linkage structure 11366 be provided on the mounting plate and drive connection plate 11364, but at least two rotating linkage structures 11366 can also be provided side by side on the mounting plate and drive connection plate 11364, with at least two rotating linkage structures 11366 connected to multiple positions of the pushing plate structure 11368. By simultaneously providing multiple rotating linkage structures 11366, they can be connected to and pushed from multiple positions to the pushing plate structure 11368, making the movement of the pushing plate structure 11368 more precise and stable.

[0039] Furthermore, the extrusion plate structure 11368 may include an extrusion plate body disposed at the end of the second curved connecting rod of the rotating connecting rod structure 11366, and an extrusion roller structure rotatably disposed on one side of the extrusion plate body. The extrusion roller structure is used to correspondingly compress the chuck 11242 of the elastic clamp 1124 mounted on the other side of the suspension clamp 1120. By rotatably disposing the extrusion roller structure on one side of the extrusion plate body, the extrusion roller structure can roll into contact with the chuck 11242 of the suspension clamp 1120, facilitating rolling compression of the chuck 11242, resulting in uniform force on the chuck 11242 and reducing the likelihood of damage.

[0040] Furthermore, the extrusion roller structure may include a rotating seat protruding from one side of the extrusion plate, a roller shaft rotatably mounted on the rotating seat, and a flexible sleeve fitted over the roller shaft. When the extrusion roller structure rolls into contact with the chuck 11242 of the suspension clamp 1120, the flexible sleeve fitted over the roller shaft contacts and presses against the chuck 11242, which can provide cushioning during the extrusion process and prevent damage to the chuck 11242.

[0041] Furthermore, the extrusion roller structure may include multiple rotating seats protruding from one side of the extrusion plate, with the roller shaft rotatably mounted on the multiple rotating seats. Each section of the roller shaft corresponding to the multiple rotating seats is fitted with a flexible sleeve. By arranging multiple rotating seats side by side on the extrusion plate to provide rotational support for the roller shaft, the entire roller shaft is subjected to balanced force and is not prone to deformation, allowing any part to squeeze and push the chuck 11242 of the suspension clamp 1120. Moreover, when multiple rotating seats are provided to provide rotational support for the roller shaft, the roller shaft can be divided into multiple shaft segments, with a flexible sleeve fitted on each shaft segment, and each flexible sleeve protruding beyond the rotating seat, allowing any flexible sleeve to squeeze and push the chuck 11242 of the suspension clamp 1120.

[0042] Furthermore, both the positioning plate 11344 and the pushing roller structure can be designed as elongated strips, allowing sufficient clamping time to hold the suspension clamp 1120 and preventing the suspension clamp 1120 from moving outside the clamping gap of the switch clamping device 1130 before the suspension clamp 1120 has been fully opened. Specifically, the positioning plate 11344 can be designed as an elongated strip; the pushing plate of the pushing roller structure can also be designed as an elongated pushing plate, and the roller shaft can also be designed as a long shaft.

[0043] In addition, such as Figures 7 to 9 As shown, the double-sided exposure machine 1600 may include an exposure machine body 1610 located at the same end of the first printing baking line 12, the second printing baking line 14, and the second return conveyor line 16, and a flipping assembly 1630 located on the exposure machine body 1610. Specifically, the exposure machine body 1610 may include a main unit and an exposure table 1620 protruding from one end of the main unit. Moreover, a first exposure position 1622 and a second exposure position 1624 are arranged side by side on the exposure table 1620. A first storage bin 2100 is correspondingly arranged with the first exposure position 1622, and a second storage bin 2200 is correspondingly arranged with the second exposure position 1624. A fourth robotic arm 1700 is correspondingly arranged with both the first storage bin 2100 and the first exposure position 1622, and a fifth robotic arm 1800 is correspondingly arranged with the second storage bin 2200, the second exposure position 1624, and the flipping assembly 1630 frame.

[0044] Moreover, such as Figure 10 As shown, the flipping assembly 1630 may include a flipping bracket 1632 disposed on the exposure stage 1620 and spanning between the first exposure position 1622 and the second exposure position 1624, a movable flipping drive mechanism 1634 disposed on the flipping bracket 1632, and a flipping suction frame 1636 disposed on the movable flipping drive mechanism 1634. The fifth robot arm 1800 is correspondingly engaged with the flipping suction frame 1636.

[0045] In some embodiments, when performing continuous exposure processing on a flexographic plate that has been printed on both sides (side A and side B), the fourth robot arm 1700 can grab the flexographic plate to be exposed from the first plate-pressing device 1900 or the first storage bin 2100 and place it at the first exposure position 1622 on the exposure table 1620 at one end of the main body of the exposure machine 1610. Then, the exposure table 1620 can be used to expose one side (such as side A) of the flexographic plate. After the exposure of side A of the flexographic plate is completed, if the exposure of side A is not qualified, the fourth robot arm 1700 can transfer the flexographic plate with unqualified exposure of side A to the first storage bin 2100.

[0046] If the A-side of the flexible plate is exposed successfully, the flipping suction frame 1636 can be moved to the first exposure position 1622 by the moving flipping drive mechanism 1634 of the flipping assembly 1630. The flexible plate with exposed A-side is then grasped and moved to the second exposure position 1624, and the flexible plate is flipped so that the unexposed side (such as the B-side) faces upward and the exposed side (A-side) faces downward. The fifth robot arm 1800 then grasps the flexible plate and places it at the second exposure position 1624 with the B-side facing upward. The B-side of the flexible plate is then exposed by the exposure table 1620. If the B-side exposure is successful, the fifth robot arm 1800 can grasp and transfer the flexible plate to the second storage bin 2200 for storage or to other workstations. If the B-side exposure is unsuccessful, the fifth robot arm 1800 can grasp and transfer the flexible plate to the second storage bin 2200 for storage.

[0047] In addition, in some other embodiments, when exposing a flexographic plate that has only one side (such as side A) printed by the printing equipment, the fourth robot arm 1700 can pick up the flexographic plate to be exposed with side A already printed from the first plate-pressing device 1900 or the first storage bin 2100, and place the flexographic plate with side A facing up on the first exposure position 1622 on the exposure table 1620 at one end of the main body of the exposure machine 1610. Then, the exposure table 1620 can be used to expose side A of the flexographic plate. After the exposure of side A of the flexographic plate is completed, if the exposure of side A is not qualified, the fourth robot arm 1700 can transfer the flexographic plate with unqualified exposure of side A to the first storage bin 2100.

[0048] If the A-side of the flexographic plate is exposed successfully, the flipping suction frame 1636 can be moved to the first exposure position 1622 by the moving flipping drive mechanism 1634 of the flipping assembly 1630. The flexographic plate with the A-side exposed can be grasped and moved to the second exposure position 1624 (or other positions close to the fifth robot 1800), and the flexographic plate can be flipped so that the unexposed side (such as the B-side) faces up and the exposed side (the A-side) faces down. The fifth robot 1800 then grasps the flexographic plate and transfers it to the rotating material frame 2300. The flexographic plate is then conveyed to the second printing and baking line 14 by the conveying device, where the B-side of the flexographic plate is printed by the printing equipment. The flexographic plate printed on side B can then be re-transported via the second return conveyor line 16 to the second plate-pressing device 2000 near the fifth robot arm 1800. The fifth robot arm 1800 then picks up the flexographic plate and places it at the second exposure position 1624 with side B facing up. The exposure table 1620 then exposes side B of the flexographic plate. If the exposure of side B is qualified, the fifth robot arm 1800 can pick up and transfer the flexographic plate to the second storage bin 2200 for storage or to other workstations. If the exposure of side B is unqualified, the fifth robot arm 1800 can pick up and transfer the flexographic plate to the second storage bin 2200 for storage.

[0049] During the double-sided exposure of the flexible plate, the fourth robotic arm 1700 or the fifth robotic arm 1800 of the loading and unloading assembly can automatically load or unload the plate. The exposure table 1620 of the exposure machine body 1610 can automatically expose the printed flexible plate. The first storage bin 2100 or the second storage bin 2200 can automatically store the flexible plate before and after exposure. Furthermore, the moving and flipping drive mechanism 1634 of the flipping assembly 1630 can drive the flipping suction frame 1636 to move between the two exposure positions of the exposure table 1620, grabbing and flipping the flexible plate at the exposure position so that the side of the flexible plate to be exposed faces upwards, facilitating exposure of both sides. This eliminates the need for manual loading and unloading, and manual flipping of the flexible plate. The double-sided exposure machine 1600 can automatically load and unload the flexible plate, and automatically move and flip it, greatly improving the efficiency of the exposure operation and thus improving the efficiency of solder resist processing.

[0050] Furthermore, such as Figure 10As shown, the moving flipping drive mechanism 1634 of the flipping assembly 1630 may include a first linear drive member 16342 disposed on the flipping bracket 1632, a first lifting drive member 16344 disposed on the first linear drive member 16342, and a rotary drive structure 16346 disposed on the first lifting drive member 16344. The flipping suction frame 1636 is disposed on the rotary drive structure 16346 and is correspondingly disposed with the fifth robot arm 1800. The first linear drive 16342 drives the flipping suction frame 1636 to reciprocate between the first exposure position 1622 and the second exposure position 1624, facilitating the transfer of the flexible plate between the two exposure positions. The first lifting drive 16344 can lift and move the flipping suction frame 1636, allowing it to move closer to or further away from the exposure position, facilitating the gripping of the flexible plate at the exposure position. The rotation drive structure 16346 can rotate the flipping suction frame 1636 and the gripped flexible plate by 180°, causing the bottom surface (e.g., side B) of the flexible plate to flip upwards and its top surface (e.g., side A) to flip downwards, allowing the fifth robot arm 1800 to grip the flipped flexible plate.

[0051] Furthermore, the first linear drive unit 16342 may include a translation base plate disposed on the front side of the flipping bracket 1632, and a first motor linear drive module and a translation guide rail disposed side by side on the translation base plate in the horizontal direction, extending between the first exposure position 1622 and the second exposure position 1624. Moreover, the first lifting drive unit 16344 may include a lifting base plate connected to the first motor linear drive module and slidably disposed on the translation guide rail, and a second motor linear drive module disposed on the lifting base plate in the vertical direction. Furthermore, the rotary drive structure 16346 may include a rotary base connected to the second motor linear drive module, a rotary drive motor disposed beside the rotary base, and a rotary transmission structure disposed on the front side of the rotary base. The rotary drive motor is connected to the rotary transmission structure, and the output shaft of the rotary transmission structure is connected to the flipping suction frame 1636.

[0052] A horizontally positioned first motor linear drive module can drive the flipping suction frame 1636 to reciprocate along a horizontally positioned translation guide rail between the first exposure position 1622 and the second exposure position 1624, allowing the flexible plate gripped by the flipping suction frame 1636 to move between the first exposure position 1622 and the second exposure position 1624. A vertically positioned second motor linear drive module can drive the flipping suction frame 1636 to move up and down in the vertical direction, allowing the flipping suction frame 1636 to move closer to or away from the first exposure position 1622 or the second exposure position 1624, facilitating the gripping of the flexible plate at the exposure position or placing the flexible plate at the exposure position. A rotary drive motor can drive the rotary transmission structure to rotate, causing the rotary transmission structure to rotate the flipping suction frame 1636, thus rotating the flexible plate gripped by the flipping suction frame 1636 by 180° to flip it over.

[0053] Furthermore, by placing the rotary drive motor on the side of the rotating base and the rotary transmission structure on the front of the rotating base, the space occupied by the rotary drive motor can be reduced, making the rotary drive structure 16346 compact and facilitating the rotary drive motor to drive the rotary transmission structure. Moreover, the rotary transmission structure may include a gear transmission structure located on the front of the rotating base, with the flipping suction frame 1636 connected to the output shaft of the gear transmission structure. The rotary drive motor can drive the gear transmission structure to rotate, causing the output shaft of the gear transmission structure to rotate, thereby driving the flipping suction frame 1636 to rotate.

[0054] Furthermore, the flipping suction frame 1636 may include a suction bracket 16362 connected to the output shaft of the rotary transmission structure of the rotary drive structure 16346, and a flipping suction plate structure 16364 protruding below the bottom of the suction bracket 16362. The rotary drive structure 16346 can drive the suction bracket 16362 to rotate, causing the suction bracket 16362 to drive the flipping suction plate structure 16364 to rotate; and the suction bracket 16362 can fix the flipping suction plate structure 16364, which can be used to suction, grasp, or release the flexible board.

[0055] Furthermore, the flip-over suction plate structure 16364 may include a suction plate connecting rod assembly protruding from the bottom of the suction bracket 16362, a suction plate connecting plate connected to the suction plate connecting rod assembly, at least two suction nozzle mounting rods located at the bottom of the suction plate connecting plate, and multiple vacuum nozzles located on each suction nozzle mounting rod. The suction plate connecting rod assembly allows the suction plate connecting plate to be suspended below the bottom of the suction bracket 16362, while the suction nozzle mounting rods at the bottom of the suction plate connecting plate allow for the installation and fixation of multiple vacuum nozzles, enabling vacuum adsorption of the flexible plate. In this embodiment, two suction nozzle mounting rods may be arranged side-by-side at the bottom of the suction plate connecting plate, each suction nozzle mounting rod having multiple vacuum nozzles evenly distributed on it, and each vacuum nozzle extending outwards from the suction nozzle mounting rod. Moreover, the suction plate connecting plate may extend laterally, while the two suction nozzle mounting rods may extend longitudinally.

[0056] Furthermore, in this embodiment, the flipping adsorption rack 1636 may include two flipping suction plate structures 16364 arranged side-by-side below the bottom of the adsorption support 16362. By arranging two flipping suction plate structures 16364 side-by-side below the bottom of the adsorption support 16362, two flexible plates can be gripped and placed simultaneously, resulting in high efficiency. Additionally, the flipping adsorption rack 1636 may also include one or more flipping suction plate structures 16364 located below the bottom of the adsorption support 16362.

[0057] In addition, such as Figures 7 to 8 ,as well as Figures 11 to 12 As shown, both the first storage bin 2100 and the second storage bin 2200 may include a storage base 2110 located outside the side of the exposure table 1620, a storage side frame 2120 protruding from the storage base 2110, a storage bin structure 2130 located on the storage base 2110, and a gripping and releasing mechanism 2140 located on the storage side frame 2120 and corresponding vertically to the storage bin structure 2130. The storage bin structure 2130 corresponds to and cooperates with the fourth robot arm 1700 or the fifth robot arm 1800. The storage bin structure 2130 can be used to store flexible boards to be tested, as well as flexible boards after exposure (i.e., flexible boards that have passed exposure can be stored, and flexible boards that have failed exposure can also be stored). In this embodiment, the storage bin structure 2130 can be used to store flexible boards that have failed exposure. Furthermore, the gripping and releasing mechanism 2140 located on the storage side frame 2120 can grip and move the flexible board in the storage compartment structure 2130, and the storage position of the flexible board can be adjusted.

[0058] Furthermore, the storage base 2110 can be equipped with multiple storage compartment structures 2130, which are staggered. The gripping and unloading mechanism 2140 is vertically aligned with each of the storage compartment structures 2130. Multiple flexible boards, and various types of flexible boards, can be stored within the multiple storage compartment structures 2130. The vertical alignment of the gripping and unloading mechanism 2140 with the multiple storage compartment structures 2130 allows the gripping and unloading mechanism 2140 to grip, unload, and transfer the flexible boards at each of the storage compartment structures 2130. Additionally, a fourth robotic arm 1700 or a fifth robotic arm 1800 is also vertically aligned with each of the multiple storage compartment structures 2130, allowing the robotic arm to pick up and place flexible boards from any of the storage compartment structures 2130.

[0059] In this embodiment, three storage compartment structures 2130 are vertically staggered on the storage base 2110. The middle storage compartment structure 2130 is slidably mounted on the storage base 2110, while the other two storage compartment structures 2130 are arranged side-by-side on either side of the storage base 2110. This allows for the sequential arrangement of three storage compartment structures 2130 along the height direction on the storage base 2110, and the staggered arrangement facilitates flexible plate loading and unloading operations on the three storage compartment structures 2130. Furthermore, by arranging the two storage compartment structures 2130 located at the low position and the two storage compartment structures 2130 located at the high position side by side on both sides of the storage base 2110, and sliding the middle storage compartment structure 2130 located on the storage base 2110, when it is necessary to remove or place the two storage compartment structures 2130 located at the low position and the two storage compartment structures 2130 located at the high position, the middle storage compartment structure 2130 can be slid to the bottom of the storage compartment structure 2130 located at the high position; and when it is necessary to remove or place the middle storage compartment structure 2130 located at the low position, it can be slid to the top of the storage compartment structure 2130 located at the low position.

[0060] Furthermore, the storage base 2110 can be equipped with two storage guide rails side by side, and a storage compartment linear drive unit arranged side by side with the storage guide rails. Of the three storage compartment structures 2130, the middle storage compartment structure 2130 is slidably mounted on the two storage guide rails and connected to the storage compartment linear drive unit. The storage compartment linear drive unit can drive the middle storage compartment structure 2130 to reciprocate between the two storage compartment structures 2130 located at the lower and higher positions. Moreover, the storage compartment linear drive unit can be configured as a motor linear drive module.

[0061] Furthermore, the material handling mechanism 2140 may include a second linear drive unit mounted on the storage side frame 2120, a second lifting drive unit mounted on the second linear drive unit, and an adsorption frame structure mounted on the second lifting drive unit. The second linear drive unit can drive the adsorption frame structure to reciprocate between multiple storage compartment structures 2130, and the second lifting drive unit can drive the adsorption frame structure to move up and down, bringing it closer to or away from the storage compartment structure 2130. The adsorption frame structure can adsorb or release the flexible plate. In addition, the structure of the second linear drive unit is similar to that of the first linear drive unit 16342, the structure of the second lifting drive unit is similar to that of the first lifting drive unit 16344, and the structure of the adsorption frame structure is also similar to that of the flipping suction plate structure 16364, which will not be described further here.

[0062] In addition, such as Figures 13 to 15 As shown, the rotating material frame 2300 may include a material frame 2310 arranged side-by-side on the side of the device frame 1910 of the second platen device 2000, and a rotating positioning table 2320 disposed on the material frame 2310. The rotating positioning table 2320 corresponds to and cooperates with the fifth robot 1800 and the sixth robot 2400. The fifth robot 1800 can pick up the flexible plate exposed on side A from the flipping suction frame 1636 and transfer it to the rotating positioning table 2320 on the material frame 2310. The rotating positioning table 2320 positions and rotates the flexible plate, adjusting its orientation so that the adjusted flexible plate can be transferred to the second printing press 700 by the sixth robot 2400, and the second printing press 700 can print ink on side B of the flexible plate.

[0063] In addition, such as Figures 13 to 15 As shown, both the first clapping device 1900 and the second clapping device 2000 may include a device frame 1910, a flexible plate conveying mechanism 1920 disposed on the device frame 1910, and a clapping mechanism 1930 disposed on the device frame 1910 and the flexible plate conveying mechanism 1920. The flexible plate conveying mechanism 1920 can receive the flexible plate conveyed by the film tearing machine 600 or the return conveyor belt 1400 in preparation for exposure. Moreover, the clapping mechanism 1930 can inspect and arrange the flexible plate on the flexible plate conveying mechanism 1920 to keep the flexible plate neat before and after exposure.

[0064] Specifically, the device frame 1910 may include a device base 1912 and a device top frame 1914 disposed on the device base 1912. The bottom of the device top frame 1914 is provided with an inlet / outlet 1916 (which is also located above the top surface of the device base 1912). Moreover, the flexible plate conveying mechanism 1920 may include a conveying frame structure 1922 disposed on the top surface of the device base 1912 and a conveying roller structure 1924 disposed on the conveying frame structure 1922. One end of the conveying roller structure 1924 corresponds to the inlet / outlet 1916 and is connected to the conveying mechanism of the film tearing machine 600 or the return conveyor belt 1400, and the other end is correspondingly engaged with the fourth robot 1700 or the fifth robot 1800.

[0065] Furthermore, the clapping mechanism 1930 may include a vision inspection mechanism 1932 located on the top of the device top frame 1914, a flexible plate height adjustment mechanism 1934 located on the side of the device top frame 1914, and a flexible plate side adjustment mechanism 1936 located on the conveyor frame structure 1922. The vision inspection mechanism 1932 and the flexible plate height adjustment mechanism 1934 are both located above the conveyor roller structure 1924, and the flexible plate side adjustment mechanism 1936 is located on both sides of the conveyor roller structure 1924. Among them, the vision inspection mechanism 1932 may be a camera vision inspection module.

[0066] The conveying roller structure 1924 of the flexible board conveying mechanism 1920, which is mounted on the device base 1912 of the device frame 1910, can connect with the film tearing machine 600 or the return conveyor belt 1400 through the inlet / outlet 1916 at the bottom of the device top frame 1914 to receive the flexible board conveyed by the film tearing machine 600 or the return conveyor belt 1400. Furthermore, the flexible board received or to be output from the conveying roller structure 1924 located on the conveying frame structure 1922 can be inspected for neatness by the visual inspection mechanism 1932 at the top of the device top frame 1914.

[0067] If the flexographic plate is detected to be misaligned, the flexographic plate height adjustment mechanism 1934 of the flexographic plate mechanism 1930 can be used to press and straighten the flexographic plate from a height position, or the flexographic plate can be grasped and moved to adjust its position. Alternatively, the flexographic plate side adjustment mechanism 1936 of the flexographic plate mechanism 1930 can be used to push and straighten the flexographic plate from the side. In this way, the received or output flexographic plates can be automatically detected, and flexographic plates that are found to be misaligned can be adjusted to keep the flexographic plates aligned. This ensures the exposure quality of the flexographic plates and the quality of subsequent exposure processing, thereby improving the quality of the flexographic plate products.

[0068] Furthermore, such as Figure 16As shown, the conveyor frame structure 1922 of the flexible plate conveying mechanism 1920 may include a conveyor frame bracket protruding from the top surface of the device base 1912, and a conveyor frame top plate disposed on top of the conveyor frame bracket. The conveyor roller structure 1924 is disposed on the conveyor frame bracket and the conveyor frame top plate. The conveyor frame bracket supports the conveyor frame top plate, and the conveyor frame top plate and the conveyor frame bracket support the conveyor roller mechanism, so that the conveyor roller structure 1924 can convey the flexible plate.

[0069] Furthermore, the conveyor frame support may include two conveyor side frames arranged side-by-side on the top surface of the device base 1912, and a baffle frame located on the front side of the two conveyor side frames. A top plate of the conveyor frame may be located between the two conveyor side frames, with its front side corresponding to the baffle frame and its rear side corresponding to the inlet / outlet 1916. Additionally, a conveyor roller structure 1924 may be located between the two conveyor side frames and corresponding to the top plate of the conveyor frame.

[0070] Furthermore, the conveyor frame structure 1922 may include a top plate lifting adjustment component disposed on the top surface of the device base 1912, and multiple lifting adjustment rods surrounding the top plate lifting adjustment component. The top drive end of the top plate lifting adjustment component is connected to the bottom of the conveyor frame top plate, and the tops of the multiple lifting adjustment rods are all connected to the bottom of the conveyor frame top plate. This allows the conveyor frame top plate to be lifted and lowered between the two conveyor side frames and the baffle frame, and the height position of the conveyor frame top plate can be adjusted to cooperate with the conveyor roller structure 1924. Specifically, the top plate lifting adjustment component allows for lifting and adjusting of the conveyor frame top plate, while the multiple lifting adjustment rods provide telescopic support for the conveyor frame top plate from multiple positions, ensuring stable and reliable lifting and adjusting of the conveyor frame top plate.

[0071] Furthermore, the top plate lifting adjustment component may include a lifting base located at the center of the top surface of the device base 1912, and a lifting drive cylinder mounted on the lifting base, with the top drive end of the lifting drive cylinder connected to the bottom of the conveyor frame top plate. This allows for simple and convenient lifting and adjustment of the conveyor frame top plate via the lifting drive cylinder. Moreover, by connecting the lifting drive cylinder to the center of the bottom of the conveyor frame top plate, the force on the conveyor frame top plate is balanced. Additionally, multiple top plate lifting adjustment components can be installed at the bottom of the conveyor frame top plate as needed, allowing for simultaneous lifting and adjustment from multiple positions.

[0072] Furthermore, a lifting adjustment rod is installed around each of the four sides of the bottom of the conveyor frame top plate. These lifting adjustment rods can be either pneumatic or hydraulic telescopic rods. This allows for four lifting adjustment rods to support the conveyor frame top plate from all four sides of the bottom. Combined with the top plate lifting adjustment component located at the center of the bottom of the conveyor frame top plate, this ensures stable and reliable lifting and support of the conveyor frame top plate. Moreover, using pneumatic or hydraulic telescopic rods provides even more stable support for the conveyor frame top plate. Additionally, a greater number of lifting adjustment rods can be installed as needed.

[0073] Furthermore, the conveyor roller structure 1924 may include a conveyor roller drive unit mounted on a conveyor side frame on one side of the conveyor frame support, and multiple conveyor rollers rotatably mounted side-by-side on the conveyor frame support in a transverse direction, with the multiple conveyor rollers mounted on a top conveyor plate. The conveyor roller drive unit can drive the multiple conveyor rollers to rotate, thereby receiving or feeding the flexible board. Moreover, the top conveyor plate may be provided with multiple limiting grooves, and the multiple conveyor rollers can be correspondingly positioned in the multiple limiting grooves. By providing multiple limiting grooves on the top conveyor plate, the multiple conveyor rollers can be limited and the gaps between the conveyor rollers can be filled, further preventing the flexible board from skewing during conveying.

[0074] Furthermore, the conveyor roller drive unit may include a roller drive motor mounted on one side of the conveyor frame support, a transmission belt structure connected to the roller drive motor, a roller drive shaft rotatably mounted on one side of the conveyor frame support along the longitudinal direction, multiple drive gears mounted on the roller drive shaft, and driven gears mounted at the ends of the roller shafts of multiple conveyor rollers, with each driven gear meshing one-to-one with the multiple drive gears. The roller drive motor drives the transmission belt structure, causing it to rotate the roller drive shaft, which in turn rotates the multiple drive gears on the roller drive shaft, which in turn rotates the multiple driven gears meshing one-to-one with the drive gears, thereby rotating the multiple conveyor rollers connected to the multiple driven gears. Thus, multiple conveyor rollers can be driven to rotate by a single roller drive motor. Moreover, the drive gears and driven gears may be bevel gear pairs (such as two orthogonal bevel gears), allowing the roller drive shaft and the roller shafts of the conveyor rollers to be perpendicular to each other.

[0075] In addition, such as Figure 16As shown, the flexible plate height adjustment mechanism 1934 may include a height adjustment frame 19342 arranged transversely on the device base 1912 along the conveying roller structure 1924, a third linear drive member 19344 arranged along the extension direction of the height adjustment frame 19342, a third lifting drive member 19346 connected to the third linear drive member 19344, and a height adjustment suction frame 19348 connected to the third lifting drive member 19346. The height adjustment frame 19342 is located on the side of the inlet / outlet 1916 and spans above the flexible plate conveying mechanism 1920. The height adjustment suction frame 19348 is arranged vertically and vertically corresponding to the conveying roller body and the top plate of the conveying frame of the conveying roller structure 1924. The third linear drive 19344 can drive the height-adjustable suction frame 19348 to move laterally back and forth along the conveyor roller and the top plate of the conveyor frame, while the third lifting drive 19346 can drive the height-adjustable suction frame 19348 to move closer to or further away from the conveyor roller and the top plate of the conveyor frame, so as to facilitate the suction and gripping or releasing of the flexible plate on the conveyor roller, thereby facilitating the movement of the flexible plate to adjust its position and make it easier to place the flexible plate neatly.

[0076] Furthermore, the third linear drive 19344 may include a third motor linear drive module and a third guide rail disposed side-by-side on the height adjustment frame 19342 in the transverse direction. The third lifting drive 19346 may include a lifting frame connected to the third motor linear drive module and slidably disposed on the third guide rail, and a lifting drive cylinder and a lifting guide rail disposed side-by-side on the lifting frame in the vertical direction. The height-adjustable adsorption frame 19348 may include an adsorption connecting frame connected to the drive end of the lifting drive cylinder and slidably disposed on the lifting guide rail, and a plurality of adsorption mounting plates disposed side-by-side at the bottom of the adsorption connecting frame in the longitudinal direction, each adsorption mounting plate being provided with a plurality of vacuum nozzles.

[0077] In addition, such as Figure 16 As shown, the flexible plate side adjustment mechanism 1936 may include a fourth linear drive 19362 disposed between two conveyor side frames of the conveyor frame structure 1922 and above multiple conveyor rollers of the conveyor roller structure 1924 in a transverse direction, and two flexible plate side sorting frames 19364 connected to the fourth linear drive 19362. The two flexible plate side sorting frames 19364 are respectively located on both sides of the conveyor roller structure 1924. The fourth linear drive 19362 can drive the flexible plate side sorting frames 19364 to move laterally back and forth along the top surface of the multiple conveyor rollers of the conveyor roller structure 1924, so as to push and sort the flexible plate located on the multiple conveyor rollers from the side, and sort the flexible plate from both sides, so as to make the flexible plate neat.

[0078] Furthermore, the conveyor frame structure 1922 has a longitudinally spaced conveyor frame partition in the middle of its top plate. This partition separates the top plate and the conveyor roller structure 1924 into two parts, with two flexible plate side-arranging frames 19364 located on either side of the partition. The partition, positioned in the middle of the top plate, divides the top plate into left and right sections, and also separates the multiple conveyor rollers on the top plate, creating two parallel conveying stations that can simultaneously convey two flexible plates. The two flexible plate side-arranging frames 19364 can push and arrange the flexible plates at the two conveying stations from the outside towards the center. Additionally, the partition in the middle of the top plate can be used to block and limit the movement of the flexible plates from the center.

[0079] Furthermore, the fourth linear drive unit 19362 may include a drive mounting bracket disposed on the conveyor frame structure 1922, an adjustment drive motor and a pulley transmission structure disposed on the drive mounting bracket and interconnected thereto, and a side adjustment guide rail extending laterally on the drive mounting bracket. Both flexible plate side sorting frames 19364 are connected to the transmission belt of the pulley transmission structure and slidably disposed on the side adjustment guide rail. The adjustment drive motor can drive the pulley transmission structure to work, causing the transmission belt of the pulley transmission structure to drive the two flexible plate side sorting frames 19364 to move laterally reciprocally along the side adjustment guide rail, so that the two flexible plate side sorting frames 19364 move laterally reciprocally above the top plate of the conveyor frame and the multiple conveyor rollers.

[0080] Furthermore, the flexible board side sorting frame 19364 may include a sorting frame seat connected to a drive belt of the pulley drive structure and slidably mounted on a side adjustment guide rail, a sorting frame rod protruding longitudinally from the sorting frame seat, and a plurality of sorting protrusions protruding below the sorting frame rod along its extension direction, the sorting protrusions being located above the conveyor roller structure 1924. The sorting frame rod of each flexible board side sorting frame 19364 extends from the inlet / outlet side 1916 of the top plate of the conveyor frame to its retainer side, so that the plurality of sorting protrusions protruding below the sorting frame rod can push the flexible board on the plurality of conveyor rollers laterally from the side, making it less prone to deviation.

[0081] In addition, such as Figures 17 to 18As shown, the first robot 200, the second robot 1000, the third robot 1200, the fourth robot 1700, the fifth robot 1800, and the sixth robot 2400 may each include a robot base 210, a robot arm 220 mounted on the robot base 210, a robot gripper 230 mounted at the end effector of the robot arm 220, and at least one robot suction plate structure 240 mounted on the robot gripper 230. The robot arm 220 can drive the robot gripper 230 and its robot suction plate structure 240 to move between different equipment stations, allowing the robot suction plate structure 240 to grasp and move flexible boards at different positions. Furthermore, the robot gripper 230 may have one robot suction plate structure 240 mounted on it, or one robot suction plate structure 240 may be mounted on each side of the robot gripper 230.

[0082] Furthermore, by setting a robotic suction plate structure 240 on each side of the robotic arm picking rack 230, both robotic suction plate structures 240 on both sides can adsorb and grasp the flexible board, resulting in high operating efficiency. Moreover, the robotic arm 220 can rotate the robotic suction plate structures 240 on both sides, which not only facilitates flipping the flexible board but also allows both robotic suction plate structures 240 to rotate to the lower position for grasping and releasing the flexible board. In addition, the structure of the robotic suction plate structure 240 is similar to that of the flipping suction plate structure 16364, and will not be described in detail here.

[0083] In addition, such as Figure 19 As shown, the present invention also proposes a flexible plate solder resist processing method, applied to the flexible plate solder resist processing system 10 described above. Specifically, the flexible plate solder resist processing method includes: S100: The first side of the flexible board is printed by the first printing press 100, and the printed flexible board is transferred to the first settling machine 300 for settling by the first robot arm 200. Then, the settling flexible board is transported to the first baking oven 400 for pre-baking. The pre-baked flexible board is then transported to the first buffer machine 500 for buffering. The flexible board is then transported to the film peeling machine 600 through the first buffer machine 500 to peel off the protective film on the second side of the flexible board. S200: The film-torn flexible board is conveyed to the first plate-setting device 1900 by the film-tearing machine 600 for sorting and arranging. Then, the fourth robot arm 1700 moves the arranged flexible board to one side of the exposure table 1620 of the double-sided exposure machine 1600 for exposure of the first side of the flexible board. If the first side of the flexible board fails the exposure test, the fourth robot arm 1700 moves the unexposed flexible board to the first storage bin 2100 for storage and unloading. When the first side of the flexible board passes the exposure test, the double-sided exposure machine 1600 flips the flexible board so that the second side of the flexible board faces upward, and the fifth robot arm 1800 moves the flexible board to the rotating material frame 2300. S300: The flexographic plate exposed on the first side is rotated by the rotating material frame 2300 to adjust its orientation. Then, the rotated flexographic plate is transferred to the second printing press 700 by the sixth robot arm 2400 to print on the second side of the flexographic plate. The printed flexographic plate is then transferred to the transfer table by the sixth robot arm 2400 to the second settling machine 900 for settling. The settling flexographic plate is then transferred to the second baking oven 1100 for baking by the second robot arm 1200. The baked flexographic plate is then transferred to the second buffer machine 1300 for buffering. The flexographic plate is then conveyed to the corner conveyor 1500 to the return conveyor belt 1400 by the second buffer machine 1300. S400: The flexographic board, which has undergone two baking processes, is conveyed to the second plate-setting device 2000 via the return conveyor belt 1400 for sorting and arranging. Then, the fifth robot arm 1800 transfers the arranged flexographic board to the other side of the exposure table 1620 of the double-sided exposure machine 1600 for exposure of the second side of the flexographic board. If the exposure of the second side of the flexographic board is unqualified, the fifth robot arm 1800 transfers the unqualified flexographic board to the defective product bin of the second storage bin 2200 for storage and unloading. If the exposure of the second side of the flexographic board is qualified, the fifth robot arm 1800 transfers the qualified flexographic board to the good product bin of the second storage bin 2200 for storage and unloading.

[0084] By connecting the double-sided exposure machine 1600 with flexographic flipping function to the film peeling machine 600 of the first printing and baking line 12 via the fourth robot 1700 and the first clapping device 1900, and connecting it to the return conveyor belt 1400 of the second return conveyor line 16 via the fifth robot 1800 and the second clapping device 2000, and connecting it to the second printing machine 700 of the second printing and baking line 14 via the fifth robot 1800, the rotating material frame 2300, and the sixth robot 2400, the flexographic film peeling machine can be connected to the film peeling machine 600 of the first printing and baking line 12 via the fifth robot 1800, the rotating material frame 2300, and the sixth robot 2400. After the first side (e.g., side A) of the flexible board is printed and baked, side A is exposed using a double-sided exposure machine 1600. The exposed flexible board is then flipped over by the double-sided exposure machine 1600 so that the second side (e.g., side B) faces upwards. The second printing and baking line 14 then begins printing and baking the second side of the flexible board. The second return conveyor line 16 then returns the flexible board to the double-sided exposure machine 1600 for another exposure of side B. After both sides of the flexible board have been exposed, it is shipped out for further development and curing. This simplifies one shipping process and eliminates one developing, one curing, and one acid washing process, reducing manpower and material consumption in these three processes, improving production efficiency, shortening product cycle time, and lowering production costs.

Then the settling flexible board is sent to the first baking oven for pre-baking. The pre-baked flexible board is then sent to the first buffer machine for buffering. The first buffer machine sends the flexible board to the film peeling machine to remove the protective film on the second side of the flexible board.

Then, the fifth robotic arm moves the arranged flexographic boards to the other side of the exposure table of the double-sided exposure machine for exposure of the second side of the flexographic boards. If the second side of the flexographic board fails the exposure test, the fifth robotic arm moves the defective flexographic board to the defective product bin of the second storage silo for storage and unloading. If the second side of the flexographic board passes the exposure test, the fifth robotic arm moves the passable flexographic board to the good product bin of the second storage silo for storage and unloading.
