Description

Technical Field

[0001] This utility model relates to the field of inkjet printing equipment technology, and in particular to an automatic loading and unloading double-sided inkjet printing machine. Background Technology

[0002] Double-sided inkjet printing is an advanced manufacturing technology primarily used for high-precision patterned printing on both sides of a substrate simultaneously or sequentially. This technology has wide applications in electronics manufacturing, packaging, and decoration, especially in printed circuit board (PCB) manufacturing, where it can efficiently print double-sided circuits, solder mask layers, and characters. Among existing patents, Chinese patent application number 202020595105.7 discloses an automatic transfer and flipping mechanism and inkjet printing system. The automatic transfer and flipping mechanism includes an unloading mechanism, a flipping mechanism, and a loading mechanism. The unloading mechanism interfaces with one inkjet printing device to unload the printed front side of the board and transfer it to the flipping mechanism. The flipping mechanism is located between the unloading mechanism and the loading mechanism to flip the board delivered by the unloading mechanism. The loading mechanism interfaces with another inkjet printing device to transfer the flipped, reverse-side-up board to the next inkjet printing device for reverse-side printing. This patent document describes an automatic transfer and flipping mechanism in the middle of the inkjet printing system to automate the printing of both sides of the PCB board. However, it requires two inkjet printers to print on both sides of the board separately, increasing production costs and failing to automate the loading and unloading of boards carried by the L-shaped rack. Therefore, the shortcomings are obvious, and a solution is urgently needed. Utility Model Content

A limit cap is installed at the top of the slide rod, which is located in the receiving hole and abuts against the bottom wall of the receiving hole. The side wall of the slide rod is slidably connected to the inner wall of the sliding hole. The trigger rod is installed at the top of the slide rod, and the contact block is installed at the bottom of the slide rod. The sensor is mounted on the base and located above the receiving hole. The trigger rod is used to trigger the sensor. The spring is sleeved on the outside of the slide rod. One end of the spring is inserted into the mounting hole and abuts against the top wall of the mounting hole, and the other end of the spring abuts against the top surface of the contact block. When the spring is in the extended state, the limit cap abuts against the bottom wall of the receiving hole, and the trigger rod is located in the receiving hole.

[0027] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0028] like Figures 1 to 9As shown, this utility model provides an automatic loading and unloading double-sided inkjet printing machine, which includes a printer 1, a loading machine 2, an unloading machine 3, an output mechanism 4, a flipping mechanism 5, and an input mechanism 6. The loading machine 2 and the unloading machine 3 are arranged side by side on one side of the printer 1, and the output mechanism 4 and the input mechanism 6 are arranged side by side on the other side of the printer 1. The flipping mechanism 5 is located between the input mechanisms 6 and 6. The loading machine 2 is used to transport materials to the transfer table of the printer 1, and the printer 1 is used to control the transfer table. The material being printed is transported by the inkjet printer 1. The transfer platform of the inkjet printer 1 conveys the material to the output mechanism 4. The flipping mechanism 5 flips the material from the output mechanism 4 and transfers it to the input mechanism 6. The input mechanism 6 then conveys the material to the transfer platform of the inkjet printer 1. The transfer platform of the inkjet printer 1 conveys the double-sided printed material to the unloading machine 3, which collects and unloads the double-sided printed material. Specifically, the loading machine 2 is correspondingly positioned to the output mechanism 4, and the unloading machine 3 is correspondingly positioned to the input mechanism 6. Preferably, the material is a board, such as a circuit board.

[0029] In practical applications, the feeding machine 2 feeds the board onto the transfer table of the inkjet printer 1. The inkjet printer 1 prints on one side of the board carried on its transfer table. Then, the transfer table of the inkjet printer 1 transfers the board after single-sided printing to the output mechanism 4. The output mechanism 4 transports the board to a preset position. Then, the flipping mechanism 5 flips the board carried on the output mechanism 4 and transfers it to the input mechanism 6. The input mechanism 6 inputs the flipped board into the inkjet printer 1. The transfer table of the inkjet printer 1 receives the flipped board, and the inkjet printer 1 prints on the other side of the board carried on its transfer table to achieve double-sided printing of the board. Then, the transfer table of the inkjet printer 1 transfers the double-sided printed board to the unloading machine 3. The unloading machine 3 unloads and collects the double-sided printed board. This invention enables double-sided printing on boards and automated loading and unloading of boards. The boards are flipped outside the printing machine 1, which greatly improves the efficiency of printing on the boards. Furthermore, by conveying the boards back and forth, the conveying time is extended, which is beneficial for the curing of ink on the printed boards and ensures the quality of the printed boards.

[0030] In this embodiment, both the loading machine 2 and the unloading machine 3 include a frame 7, a rack receiving and positioning device 8 mounted on the frame 7 for receiving and positioning the L-shaped rack 45, a translation drive mechanism 9 disposed in the middle of the rack receiving and positioning device 8, a first lifting drive mechanism 10 for driving the translation drive mechanism 9 to rise and fall, a pick-up and flipping device 11 mounted on the translation end of the translation drive mechanism 9, a feeding mechanism 12 disposed on the side of the rack receiving and positioning device 8 near the inkjet printer 1, and a second lifting drive mechanism 13 for driving the feeding mechanism 12 to rise and fall; the pick-up and flipping device 11 is used to flip and transfer the material between the rack receiving and positioning device 8 and the feeding mechanism 12; the feeding mechanism 12 has a flipping space 14 in the middle, which provides space for the pick-up and flipping end of the pick-up and flipping device 11.

[0031] In practical applications, the feeding machine 2 vertically stacks the boards to be printed on the L-shaped material rack 45. The L-shaped material rack 45, filled with boards, is then placed on the material rack receiving and positioning device 8. The material rack receiving and positioning device 8 supports and positions the L-shaped material rack 45, ensuring its positional accuracy and stability. Next, the translation drive mechanism 9 drives the picking and flipping device 11 to move closer to the boards on the L-shaped material rack 45 until the picking and flipping device 11 picks up the boards. Then, the first lifting drive mechanism 10 drives the translation drive mechanism 9, along with the picking and flipping device 11 and the boards, to rise, causing the bottom edge of the boards to separate from the L-shaped material rack 45. Finally, the translation drive mechanism 9 drives the picking and flipping device 11, along with the boards, to move closer to the feeding mechanism 12 and onto the flipping plate. The 17 pieces are positioned, and then the picking and flipping device 11 flips the picked-up pieces above the feeding mechanism 12, so that the pieces are flipped from an upright state to a horizontal state. Then, the first lifting drive mechanism 10 drives the translation drive mechanism 9 to lower the picking and flipping device 11 and the flipped pieces until the pieces are placed on the feeding mechanism 12. The picking and flipping end of the picking and flipping device 11 is in the flipping space 14. The feeding mechanism 12 transports the pieces to the top of the transfer table of the inkjet printer 1. The second lifting drive mechanism 13 drives the feeding mechanism 12 to lower the pieces until the feeding mechanism 12 places the pieces on the transfer table of the inkjet printer 1. The inkjet printer 1 prints on the pieces. The loading machine 2 transports the pieces stacked on the L-shaped material rack 45 one by one to the transfer table of the inkjet printer 1. The feeding mechanism 2 of this structure can not only lift the plate first and then move it horizontally to avoid friction between the plate and the L-shaped material rack 45, but also place the plate horizontally on the feeding mechanism 12 to ensure the stability of the plate and prevent damage to the plate.

[0032] In practical applications, the unloaded L-shaped material rack 45 is placed on the material rack receiving and positioning device 8. The material rack receiving and positioning device 8 supports and positions the L-shaped material rack 45, ensuring the positional accuracy and stability of the L-shaped material rack 45. At this time, the picking and turning end of the picking and turning device 11 is located within the turning space 14. After the inkjet printer 1 completes double-sided printing on the board, the double-sided printed board carried by the transfer table of the inkjet printer 1 is transferred to the feeding mechanism 12 of the loading machine 2. The feeding mechanism 12 transports the board to above the picking and turning end of the picking and turning device 11. Then, the first lifting drive mechanism 10 drives the picking and turning device 11 to rise, so that the picking and turning end of the picking and turning device 11 picks up the feeding machine. The second lifting drive mechanism 13 drives the feeding mechanism 12 to descend, causing the feeding mechanism 12 to separate from the board. Then, the picking and flipping end of the picking and flipping device 11 flips the board from a horizontal state to an upright state. Then, the translation drive mechanism 9 drives the picking and flipping device 11 and the board to move closer to the L-shaped material rack 45 until the board moves to the actual position of the L-shaped material rack 45. Then, the first lifting drive mechanism 10 drives the translation drive mechanism 9 and the picking and flipping device 11 and the board to descend until the board is placed upright on the L-shaped material rack 45. The unloading machine 3 places the double-sided printed boards one by one on the L-shaped material rack 45, and stacks multiple boards upright on the L-shaped material rack 45. The unloading mechanism 3 of this structure can not only horizontally pick up the plates from the feeding mechanism 12, ensuring the stability of the plate picking and preventing damage to the plates, but also first move the plates into position before placing them on the L-shaped material rack 45, avoiding friction between the plates and the L-shaped material rack 45.

[0033] In this embodiment, the picking and flipping device 11 includes a U-shaped base 15 mounted on the translation end of the translation drive mechanism 9, a rotating shaft 16 rotatably connected to the U-shaped base 15, a flipping plate 17 mounted on the rotating shaft 16, a rotation driver 18 mounted on the U-shaped base 15 and used to drive the rotating shaft 16 to rotate, and a plurality of suction cups 19 mounted on the flipping plate 17. The suction cups 19 are used to clamp the plate. The flipping plate 17 can be flipped into the flipping space 14. The rotating shaft 16 is located in the U-shaped base 15. Specifically, the rotation driver 18 can be a motor.

[0034] In practical applications, the rotary driver 18 drives the rotating shaft 16 to reciprocate within a preset angle range. The rotating shaft 16, together with the flipping plate 17 and multiple suction cups 19, rotates synchronously, enabling the flipping plate 17 and multiple suction cups 19 to reciprocate between the upright state and the horizontal state, thereby realizing the conversion of the plate picked up by the picking and flipping device 11 between the upright state and the horizontal state.

[0035] In this embodiment, the picking and flipping device 11 also includes a positioning controller 20 installed on the flipping plate 17; the translation drive mechanism 9 and the first lifting drive mechanism 10 are both electrically connected to the positioning controller 20. In the feeding machine 2, the translation drive mechanism 9 drives the picking and flipping device 11 to move closer to the L-shaped material rack 45 until the plate triggers the positioning controller 20, indicating that the picking and flipping device 11 has moved into position. At this time, the picking and flipping end (multiple suction cups 19) of the picking and flipping device 11 picks up the plate. The positioning controller 20 sends feedback signals to the translation drive mechanism 9 and the first lifting drive mechanism 10 respectively, so that the translation drive mechanism 9 first stops driving the picking and flipping device 11 to move. After the first lifting drive mechanism 10 drives the translation drive mechanism 9, along with the picking and flipping device 11 and the plate, to rise, and the plate separates from the L-shaped material rack 45, the translation drive mechanism 9 then drives the picking and flipping device 11, along with the plate, to move closer to the feeding mechanism 12.

[0036] In this embodiment, the positioning controller 20 includes a slide rod 21, a sensor 22, a base 23, a contact block 24, a trigger rod 25, and a spring 26. The base 23 is mounted on the flip plate 17 and has a receiving hole 27, a sliding hole 28, and a mounting hole 29 coaxially arranged on the base 23. The slide rod 21 slides through the receiving hole 27, the sliding hole 28, and the mounting hole 29. A limit cap 30 is installed at the top of the slide rod 21. The limit cap 30 is located in the receiving hole 27 and is used to abut against the bottom wall of the receiving hole 27. The side wall of the slide rod 21 is slidably connected to the inner wall of the sliding hole 28. The trigger rod 25 is installed on the top of the slide rod 21. At the end of the slide bar 21, the contact block 24 is installed at the bottom end of the slide bar 21, the sensor 22 is installed on the base 23 and located above the receiving hole 27, the trigger rod 25 is used to trigger the sensor 22, the spring 26 is sleeved on the slide bar 21, one end of the spring 26 is inserted into the mounting hole 29 and abuts against the top wall of the mounting hole 29, and the other end of the spring 26 abuts against the top surface of the contact block 24; when the spring 26 is in the extended state, the limit cap 30 abuts against the bottom wall of the receiving hole 27, the trigger rod 25 is located in the receiving hole 27, and the translation drive mechanism 9 and the first lifting drive mechanism 10 are both electrically connected to the sensor 22.

[0037] In practical applications, the translation drive mechanism 9 of the feeder 2 drives the pick-up and flip device 11 to move closer to the L-shaped material rack 45. As the pick-up and flip device 11 moves, the contact block 24 of the positioning controller 20 will first contact the plate, and the plate will apply a squeezing force to the contact block 24, causing the contact block 24 and the slide rod 21 to slide along the slide hole 28. The contact block 24 compresses the spring 26 until the trigger rod 25 moves out of the receiving hole 27 and triggers the sensor 22. When the sensor 22 is triggered, it indicates that the pick-up and flip device has been successfully flipped. When device 11 is moved into position, multiple suction cups 19 are just right to grip the board. Sensor 22 sends signals to translation drive mechanism 9 and first lifting drive mechanism 10 respectively, causing translation drive mechanism 9 to stop driving the picking and flipping device 11 to move. Then, the first lifting drive mechanism 10 drives translation drive mechanism 9, along with the picking and flipping device 11 and the board it picks up, to rise until the board is separated from the L-shaped material rack 45. Then, translation drive mechanism 9 drives the picking and flipping device 11 to move closer to the feeding mechanism 12.

[0038] In this embodiment, the output mechanism 4 includes an output module 31 for conveying materials and an output lifting drive mechanism 32 for driving the output module 31 to rise and fall. Guide plates or clapping mechanisms are provided on both sides of the output module 31. In practical applications, the transfer table of the inkjet printer 1 easily tears the single-sided printed board to the top of the output module 31. Then, the output lifting drive mechanism 32 drives the output module 31 to rise until the output module 31 lifts the board. The output module 31 outputs the single-sided printed board out of the inkjet printer 1. During the output process of the output module 31, the guide plate guides the board, or the clapping mechanism claps the board to center it, ensuring the positional accuracy and stability of the output module 31 in conveying the board and preventing the board from deviating during the process of the output module 31 conveying the board.

[0039] In this embodiment, the input mechanism 6 includes an input module 33 for conveying materials and an input lifting drive mechanism 34 for driving the input module 33 to rise and fall. Guide plates or clapping mechanisms are provided on both sides of the input mechanism 6. In practical applications, the input module 33 conveys the flipped board to the top of the transfer table of the inkjet printer 1. Then, the input lifting drive mechanism 34 drives the input module 33, along with the board, to descend until the transfer table of the inkjet printer 1 carries the board, after which the inkjet printer 1 prints on the board. During the process of the input module 33 inputting the board into the inkjet printer 1, the guide plate guides the board, or the clapping mechanism centers the board, ensuring the positional accuracy and stability of the board conveyed by the input module 33 and preventing the board from deviating during the conveying process.

[0040] Specifically, the output module 31, the input module 33, and the feeding mechanism 12 can all be two parallel conveyor belt modules.

[0041] In this embodiment, guide plates or clapping mechanisms are provided on both sides of the feeding mechanism 12. During the process of the feeding mechanism 12 conveying the plate, the guide plates guide the plate, or the clapping mechanisms clap and center the plate, ensuring the positional accuracy and stability of the plate conveyed by the feeding mechanism 12 and preventing the plate from deviating during the conveying process.

[0042] In this embodiment, the flipping mechanism 5 includes a U-shaped base 35, a rotating shaft 36 rotatably connected to the U-shaped base 35, a rotation driver 37 mounted on the U-shaped base 35 and used to drive the rotating shaft 36 to rotate, a flipping frame 38 mounted on the rotating shaft 36, a plurality of suction cups 39 mounted on the flipping frame 38, and a flipping lifting drive mechanism 40 for driving the U-shaped base 35 to rise and fall. The input module 33 is recessed with a receiving groove 41 for accommodating the flipping frame 38 and enabling the flipping frame 38 to rise and fall. Specifically, the rotation driver 37 can be a motor, and the rotating shaft 36 is located inside the U-shaped base 35.

[0043] In practical applications, the rotary driver 37 drives the rotating shaft 36 to rotate. The rotating shaft 36 drives the flipping frame 38 and multiple suction cups 39 to rotate synchronously. The flipping frame 38 and multiple suction cups 39 reciprocate between the output mechanism 4 and the input mechanism 6. When the flipping frame and multiple suction cups 39 flip to the top of the output mechanism 4, and the suction surface formed by the multiple suction cups 39 is parallel to the conveying surface of the output mechanism 4, the flipping lifting drive mechanism 40 drives the U-shaped seat 35 to move down synchronously along with the rotating shaft 36, the flipping frame 38, and the multiple suction cups 39 until the multiple suction cups 39 firmly adhere to the output mechanism 4. The plate is lifted, and then the flipping and lifting drive mechanism 40 drives the U-shaped seat 35, along with the rotating shaft 36, the flipping frame 38, multiple suction cups 39, and the plate to rise. Then, the rotating drive 37 drives the flipping frame 38 and multiple suction cups 39 to flip over to above the input mechanism 6, and the plate held by the multiple suction cups 39 is parallel to the conveying surface of the input mechanism 6. Then, the flipping and lifting drive mechanism 40 drives the U-shaped seat 35, along with the rotating shaft 36, the flipping frame 38, and multiple suction cups 39 to move down synchronously, so that the flipping frame 38 can descend into the receiving groove 41 until the plate is placed on the conveying surface of the input mechanism 6.

[0044] In this embodiment, the material rack receiving and positioning device 8 includes two roller guide rails 42 mounted parallel to the frame 7, two front stops 43 respectively disposed at one end of the two roller guide rails 42 near the feeding mechanism 12, and a rear stop mechanism 44 disposed at one end of the two roller guide rails 42 away from the feeding mechanism 12. The translation drive mechanism 9 is located between the two roller guide rails 42.

[0045] In practical applications, the L-shaped material rack 45 is placed on two roller guide rails 42, and then the L-shaped material rack 45 is pushed so that it slides along the roller guide rails 42 until the front end of the L-shaped material rack 45 abuts against the front stop block 43. Then the rear stop mechanism 44 works to block the rear end of the L-shaped material rack 45. The front stop block 43 and the rear stop mechanism 44 cooperate to limit the L-shaped material rack 45 on the two roller guide rails, which improves the positional accuracy and stability of the L-shaped material rack 45. In addition, the setting of the roller guide rollers facilitates the loading and unloading of the L-shaped material rack 45, making the loading and unloading of the L-shaped material rack 45 easier.

[0046] Specifically, the back gauge mechanism 44 includes a fixed seat, a cylinder, and a back stop. The middle part of the back stop is rotatably connected to the fixed seat. The cylinder body is hinged to the frame 7. The piston rod of the cylinder is hinged to one end of the back stop. The piston rod of the cylinder extends and retracts to drive the back stop to rotate. The other end of the back stop is used to block the rear end of the L-shaped material rack 45 carried by the two roller guide rails 42.

[0047] In practical applications, when the front end of the L-shaped material rack 45 on the roller guide rail 42 abuts against the front stop block 43, the piston rod of the cylinder extends and drives the rear stop block to rotate, so that the rear stop block can abut against the rear end of the L-shaped material rack 45, thereby limiting the L-shaped material rack 45 on the roller guide rail 42. When it is necessary to remove the L-shaped material rack 45 from the roller guide rail 42, the piston rod of the cylinder retracts and drives the rear stop block to rotate in the opposite direction, so that the rear stop block releases its obstruction of the L-shaped material rack 45, at which point the L-shaped material rack 45 can be pushed outward onto the material cart 47.

[0048] In this embodiment, the frame 7 is equipped with two docking and locking mechanisms 46. The docking and locking mechanisms 46 are used to dock and lock the material cart 47 that conveys the L-shaped material rack 45. The two docking and locking mechanisms 46 are respectively set one-to-one with the loading machine 2 and the unloading machine 3. In practical applications, the material cart 47 is pushed to the two docking and locking mechanisms 46 of the frame 7, and the two docking and locking mechanisms 46 lock the material cart 47, so that the material cart 47 docks with the two roller guide rails 42. At this time, the L-shaped material rack 45 on the material cart 47 can be easily pushed onto the two roller guide rails 42, or the L-shaped material rack 45 on the two roller guide rails 42 can be easily pushed onto the material cart 47.

[0049] In this embodiment, the feeding mechanism 12, the output module 31, and the input module 33 all extend cantilevered into the inkjet printer 1. This structural design facilitates the feeding mechanism 12 to transport the workpiece to the transfer table of the inkjet printer 1, the transfer table of the inkjet printer 1 to transfer the workpiece to the output module 31, and the input module 33 to transport the workpiece to the transfer table of the inkjet printer 1.

[0050] All technical features in this embodiment can be freely combined according to actual needs.

[0051] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
