Figure 2 This is a front view of an inkjet printing device according to an embodiment of this application. Figure 3 This is a top view of an inkjet printing device according to an embodiment of this application.

[0042] Combination Figures 1 to 3 An embodiment of this application provides an inkjet printing device, including a printing device and a flip-plate device 400.

[0043] The printing device includes a printing mechanism 100 and a transfer mechanism 200. The transfer mechanism 200 includes a first transfer rail 220 and a printing platform 210 connected to the first transfer rail 220. The printing platform 210 is used to place the workpiece 800 to be processed, and the first transfer rail 220 is used to transport the printing platform 210. The printing mechanism 100 includes a print head 110, which is used to spray ink onto the workpiece 800.

[0044] The flipping device 400 includes a rotating mechanism 410 and a conveying mechanism 420. The rotating mechanism 410 includes a first gripping component 411 and a first rotating drive module 412. The conveying mechanism 420 includes a second gripping component 421 and a second transmission track 422. The second gripping component 421 is used to grip the workpiece 800 to be processed, and the second transmission track 422 is used to transfer the workpiece 800 to be processed to the rotating mechanism 410. When the second transmission track 422 transfers the workpiece 800 to the rotating mechanism 410, the second gripping component 421 is used to grip the workpiece 800 to be processed, and the first rotating drive module 412 is used to rotate the workpiece 800 to be processed.

[0045] Specifically, both the first gripping assembly 411 and the second gripping assembly 421 are configured to switch between a first state of being fixed to the workpiece 800 and a second state of being released from the workpiece 800. A first rotation drive module 412 is connected to the first gripping assembly 411 and is used to drive the first gripping assembly 411 to rotate vertically. A second transfer track 422 is connected to the second gripping assembly 421 and is used to drive the second gripping assembly 421 to move between a first position above the printing platform 210 and a second position above the first gripping assembly 411.

[0046] The second gripping component 421 is moved to the first position by the second transmission rail 422. When the second gripping component 421 is switched to the first state, it is fixed to the workpiece 800 on the printing platform 210. At this time, the second gripping component 421 is moved to the second position by the second transmission rail 422, which moves the workpiece 800 to the position corresponding to the first gripping component 411. At this time, the first gripping component 411 is switched to the first state and fixed to the workpiece 800. The second gripping component 421 is switched to the second state and releases the workpiece 800, thus realizing the function of moving the workpiece 800 on the printing platform 210 to the rotating mechanism 410. It can be understood that the process of moving the workpiece 800 on the rotating mechanism 410 to the printing platform 210 is the reverse of the above process, and will not be described in detail here.

[0047] When a workpiece 800 is present on the rotating mechanism 410, the first rotating drive module 412 drives the first gripping assembly 411 to rotate vertically, thereby rotating the workpiece 800 on the first gripping assembly 411. This continues until the first rotating drive module 412 drives the first gripping assembly 411 to rotate vertically 180°, at which point the workpiece 800 on the first gripping assembly 411 is flipped. At this point, the workpiece 800 can be moved to the printing platform 210 via the conveying mechanism 420 for inkjet printing on the back side of the workpiece 800.

[0048] In this embodiment, neither the first position nor the second position is limited to a fixed position. For example, the first position may include the position above the two printing platforms 210. When the flipping device 400 includes two rotating mechanisms 410, the second position may include the position above the two first gripping components 411 corresponding to the two rotating mechanisms 410.

[0049] In addition, after the workpiece 800 has completed double-sided inkjet printing, the workpiece 800 on the printing platform 210 can be moved to other workstations by the conveying mechanism 420.

[0050] The inkjet printing equipment of this embodiment can meet the double-sided printing requirements of, for example, PCB parts 800 awaiting processing, through the cooperation of the printing device and the flip-plate device 400.

[0051] In some embodiments, the transplanting mechanism 200 is arranged along a horizontal first direction Y, and at least two transplanting mechanisms 200 are spaced apart along a second direction X. The printing mechanism 100 further includes a third transmission rail 120, which is arranged along the second direction X and connected to the print head 110. The third transmission rail 120 is used to drive the print head 110 to move along the second direction X. The second direction X is angled relative to the first direction Y. For ease of description, the following description uses two transplanting mechanisms 200 spaced apart along the second direction X as an example.

[0052] Both transfer mechanisms 200 have their first transfer tracks 220 set along a horizontal first direction Y. Therefore, driven by the two first transfer tracks 220, the printing platforms 210 of both transfer mechanisms 200 move along the first direction Y. The third transfer track 120 is set along a second direction X. The third transfer track 120 can drive the print head 110 to move along the second direction X. Since the first direction Y and the second direction X are set at an angle, the print head 110 can move to positions corresponding to the two printing platforms 210 to perform inkjet printing on the workpieces 800 (e.g., PCBs) on the two printing platforms 210.

[0053] Combination Figure 4Optionally, the printing mechanism 100 is located above the two transfer mechanisms 200, and the two first transfer rails 220 pass under the third transfer rail 120. Correspondingly, the two printing platforms 210 can also pass under the third transfer rail 120 under the drive of the two first transfer rails 220. When the two printing platforms 210 move under the third transfer rail 120 under the drive of the two first transfer rails 220, the third transfer rail 120 can drive the print head 110 to move above any printing platform 210 to perform inkjet printing on the workpiece 800 on that printing platform 210. Thus, the printing needs of the workpiece 800 on the two transfer mechanisms 200 can be met by the same printing mechanism 100, which is beneficial to improve inkjet printing efficiency while ensuring it.

[0054] Optionally, the first direction Y is perpendicular to the second direction X, which makes it easier to achieve vertical alignment between the printing platform 210 and the print head 110, easier to adjust and control the position, and more efficient when adjusting the position.

[0055] Optionally, the first transmission track 220 includes a first linear module, which is arranged along a first direction Y, and the third transmission track 120 includes a second linear module, which is arranged along a second direction X and is located above the first linear module.

[0056] Of course, the first transfer track 220 and the third transfer track 120 may also include a first lifting drive structure (such as a ball screw lifting structure, a telescopic motor, etc.) to meet the lifting requirements of the printing platform 210 or the print head 110. In addition, the first transfer track 220 and the third transfer track 120 may also adopt a robotic arm or other structural form, which will not be described in detail here.

[0057] In some embodiments, the inkjet printing apparatus further includes a support platform 240 and a crossbeam 250. A transplanting mechanism 200 is mounted on the support platform 240. The crossbeam 250 is located above the transplanting mechanism 200 and extends along a second direction X. The crossbeam 250 is fixedly connected to the support platform 240. The print head 110 is slidably connected to the crossbeam 250. A third transfer track 120 is mounted on the crossbeam 250.

[0058] Specifically, such as Figure 4As shown, the support platform 240 includes a support frame 241 and a bed 242 located above the support frame 241. The support frame 241 supports and fixes the bed 242, keeping the bed 242 stably in a horizontal state. Two moving mechanisms are installed above the bed 242. A crossbeam 250 extends along the second direction X, and its two ends are fixedly connected to the platform through two columns located above the platform and on both sides of the two transplanting mechanisms 200. The crossbeam 250 spans above the two transplanting mechanisms 200. The print head 110 slides with the crossbeam 250 through a slide rail located on one side of the crossbeam 250. A third transmission rail 120 is installed on the upper side of the crossbeam 250, and the execution end of the third transmission rail 120 is fixedly connected to the print head 110. When the execution end of the third transmission rail 120 moves along the crossbeam 250, it can drive the print head 110 to slide along the crossbeam 250.

[0059] Combination Figure 4 In some embodiments, as shown in the figure, the printing platform 210 is horizontally rotatably connected to the first transfer track 220, and the transfer mechanism 200 further includes a second rotation drive module 230. The second rotation drive module 230 is connected to the printing platform 210 and the first transfer track 220, and is configured to move under the drive of the first transfer track 220 and drive the printing platform 210 to rotate horizontally.

[0060] Specifically, the printing platform 210 is rotatably connected to the first transmission track 220 via a vertical rotating shaft located at the execution end of the first transmission track 220. The second rotary drive module 230 includes a rotary drive motor, which can be a DD motor. The output end of the rotary drive motor is connected to the printing platform 210 for transmission. When the rotary drive motor is running, it can drive the printing platform 210 to rotate horizontally. This allows adjustment of the angle of the workpiece 800 on the printing platform 210, ensuring accurate positioning of the workpiece 800.

[0061] Combination Figure 5 Optionally, the printing platform 210 includes a table 211 and at least one first vacuum suction head 212 disposed on the table 211. The first vacuum suction head 212 is connected to a negative pressure device, which uses the negative pressure provided by the negative pressure device to adsorb the workpiece 800, thereby preventing relative displacement between the workpiece 800 and the printing platform 210 when the printing platform 210 moves or rotates, and further ensuring accurate positioning of the workpiece 800. When it is necessary to remove the workpiece 800 from the printing platform 210, the first vacuum suction head 212 stops vacuuming, allowing the workpiece 800 to be easily removed from the printing platform 210.

[0062] Optionally, multiple first vacuum suction heads 212 are provided, and the multiple first vacuum suction heads 212 are arranged circumferentially on the upper side of the table 211, so as to better adsorb the workpiece 800 to be processed.

[0063] In some embodiments, the inkjet printing device further includes a positioning device 300, which is signal-connected to the second rotary drive module 230. The positioning device 300 is used to detect the position information of the workpiece 800 on the printing platform 210. The second rotary drive module 230 is configured to drive the printing platform 210 to rotate horizontally based on the position information of the workpiece 800.

[0064] The positioning device 300 can be a CCD camera or other image-taking positioning device 300. By acquiring images of the workpiece 800, the current position information of the workpiece 800 is determined. The control system of the second rotary drive module 230 controls the operation of the actuators in the second rotary drive module 230 based on the position information acquired by the positioning device 300, so that the workpiece 800 is rotated to the required angle.

[0065] Optionally, the positioning device 300 is signal-connected to the third transmission track 120, which is configured to drive the print head 110 to move based on the position information of the workpiece 800. Thus, the third transmission track 120 can accurately move the print head 110 to the printing position, ensuring the accuracy of inkjet printing.

[0066] Optionally, the positioning device 300 is also signal-connected to the first transmission track 220, and the third transmission track 120 is configured to drive the printing platform 210 to move based on the position information of the workpiece 800.

[0067] Optionally, the positioning device 300 is mounted on the crossbeam 250, for example, on the side of the crossbeam 250 opposite to the print head 110.

[0068] Optionally, the positioning device 300 is slidably connected to the crossbeam 250 along the second direction X, and the position of the print head 110 can be adjusted as needed to meet the usage requirements of different positions, or to avoid other components.

[0069] Optionally, the inkjet printing setup also includes a fourth motion drive module connected to the positioning device 300 to drive the positioning device 300 to slide along the crossbeam 250; or, the positioning device 300 is connected to a third transfer track 120, which drives the positioning device 300 to slide along the crossbeam 250.

[0070] In some embodiments, the inkjet printing apparatus further includes a cleaning device 500 for cleaning the printhead 110.

[0071] The cleaning device 500 of this embodiment can take many forms, and no specific limitation is made here. For example, the cleaning device 500 includes a collection box and a cleaning structure. The cleaning structure includes a scraping structure such as a protrusion, or includes a printhead and a vacuum suction head. The cleaning structure is installed in the collection box. When the third transmission track 120 drives the printhead 110 to move above the collection box, the cleaning structure can clean the printhead. The ink and other materials generated during cleaning can fall into the collection box for collection.

[0072] Combination Figure 4 Optionally, the cleaning device 500 is located at one end of the crossbeam 250. The inkjet printing equipment also includes a third rotary drive module 510, which is mounted at one end of the crossbeam 250 and connected to the cleaning device 500 for driving the cleaning device 500 to rotate horizontally. For example, the cleaning device 500 is rotatably connected to one end of the crossbeam 250 via a vertically arranged rotating shaft. The third rotary drive module 510 includes a first rotary motor and a transmission assembly. The first rotary motor is mounted on the crossbeam 250 and connected to the cleaning device 500 or the rotating shaft of the cleaning device 500 via the transmission assembly. The transmission assembly can be a gear set or a synchronous belt, etc. When the first rotary motor is running, it can drive the cleaning device 500 to rotate horizontally.

[0073] Optionally, the third rotary drive module 510 is configured to drive the cleaning device 500 to rotate between a first angle parallel to the crossbeam 250 and a second angle perpendicular to the crossbeam 250. When the cleaning device 500 is at the first angle, the print head 110 can be moved to the position of the cleaning device 500 via the third transfer track 120 to perform the cleaning operation. When the cleaning device 500 is at the second angle, the cleaning device 500 can be prevented from affecting the movement of other components such as the print head 110.

[0074] In some embodiments, the inkjet printing apparatus further includes an electrostatic eliminator 600, which may be an ionizer bar, and the moving path of the printing platform 210 passes beneath the electrostatic eliminator 600. Optionally, the electrostatic eliminator 600 is mounted on the crossbeam 250. The electrostatic eliminator 600 can remove static electricity, preventing static electricity from adversely affecting the inkjet printing quality.

[0075] In some embodiments, the inkjet printing apparatus further includes a height measuring device 700, which is signal-connected to the first transmission rail 220. The height measuring device 700 is used to measure the height information of the workpiece 800 on the printing platform 210. The first transmission rail 220 is configured to perform start-stop control based on the height information of the workpiece 800 and the pre-stored height information of the bottom of the crossbeam 250.

[0076] For example, the height measuring device 700 includes a laser rangefinder or a contact height measuring switch, which measures the height of the workpiece 800 on the printing platform 210 in a non-contact or contact manner.

[0077] For example, the first transfer track 220 is configured to drive the printing platform 210 to move when the height of the workpiece 800 is less than the height of the bottom of the crossbeam 250, and to stop driving the printing platform 210 to move when the height of the workpiece 800 is greater than or equal to the height of the bottom of the crossbeam 250. This can prevent the workpiece 800 from being scratched and damaged by the bottom of the crossbeam 250.

[0078] Optionally, there are multiple height measuring devices 700. Some of the height measuring devices 700 are used to measure the height information of the workpiece 800 to be processed on one of the printing platforms 210 and are signal-connected to one of the first transmission rails 220. Other height measuring devices 700 are used to measure the height information of the workpiece 800 to be processed on another printing platform 210 and are signal-connected to another first transmission rail 220.

[0079] Combination Figure 7 In some embodiments, the number of rotating mechanisms 410 and conveying mechanisms 420 in the flipping device 400 is the same as the number of transfer mechanisms 200. The number of rotating mechanisms 410 corresponds one-to-one with the number of transfer mechanisms 200, and the number of conveying mechanisms 420 also corresponds one-to-one with the number of transfer mechanisms 200. Each conveying mechanism 420 is configured to transfer the workpiece 800 to be processed on its corresponding transfer mechanism 200 to its corresponding rotating mechanism 410. Exemplarily, the number of rotating mechanisms 410 and conveying mechanisms 420 in the flipping device 400 is equal to the number of transfer mechanisms 200 in the printing device. Each transfer mechanism 200 is provided with one conveying mechanism 420 and one rotating mechanism 410. Therefore, the workpieces 800 on at least two transfer mechanisms 200 can be independently conveyed and flipped by their corresponding conveying mechanisms 420 and rotating mechanisms 410, effectively improving the efficiency of inkjet printing.

[0080] Optionally, the flipping device 400 also includes a frame, which is formed by combining sheet metal and rods. The frame is provided with at least two slide rail assemblies along the first direction Y. At least two conveying mechanisms 420 are respectively disposed on the at least two slide rail assemblies, and the second transmission rail 422 of the conveying mechanism 420 is installed on the lower side of the corresponding slide rail assembly. At least two rotating mechanisms 410 are correspondingly disposed below the at least two slide rail assemblies. When the second transmission rail 422 can move the workpiece 800 to the position of the corresponding rotating mechanism 410 along the corresponding slide rail assembly, it can facilitate rotation operation.

[0081] Combination Figure 8Optionally, the second transmission track 422 includes a third linear module and a second lifting drive structure. The third linear module is arranged along the slide rail assembly and located on the lower side of the slide rail assembly. The execution end of the third linear module is connected to the second lifting drive structure. The second lifting drive structure can be a ball screw lifting structure, a telescopic motor, etc. The execution end of the second lifting drive structure is connected to the second gripping component 421. The third linear module and the second lifting drive structure cooperate to drive the second gripping component 421 to translate or lift.

[0082] Optionally, the first rotary drive module 412 is fixedly mounted on the frame. The first rotary drive module 412 includes a second rotary motor. The first gripping component 411 is mounted on the motor shaft of the second rotary motor. When the second rotary motor is running, it can drive the first gripping component 411 to rotate horizontally.

[0083] Optionally, the first rotary drive module 412 includes two second rotary motors arranged opposite to each other. Each second rotary motor is equipped with a corresponding first gripping component 411. The two second rotary motors are configured to operate synchronously, and the two first gripping components 411 located on the two rotary motors are also configured to operate synchronously. When the workpiece 800 is rotated, it can be moved between the two first gripping components 411, and the two gripping components fix the two sides of the workpiece 800 respectively. At this time, the two second rotary motors operate synchronously to achieve the vertical rotation of the workpiece 800. This symmetrical arrangement makes the rotation of the workpiece 800 more stable, avoids damage caused by unilateral force on the workpiece 800, and also prevents the first gripping components 411 from contaminating the workpiece 800.

[0084] Combination Figure 9 Optionally, the first gripping assembly 411 includes a mounting plate 411a and a plurality of first clamping members 411b. The middle part of the mounting plate 411a is fixedly connected to the motor shaft of the second rotary motor. The plurality of first clamping members 411b are mounted on the mounting plate 411a and are respectively placed on both sides of the motor shaft of the second rotary motor. The first clamping members 411b can be gripper cylinders, capable of clamping the side of the workpiece 800 to be processed. When the second rotary motor is running, it can drive the mounting plate 411a and the plurality of first clamping members 411b to rotate vertically.

[0085] Combination Figure 10 Optionally, the second gripping component 421 includes a second vacuum suction head 421a, which is disposed downward and used to adsorb the workpiece 800 to be processed. Specifically, the second vacuum suction head 421a is installed on the lower side of the second lifting drive structure. The second vacuum suction head 421a can adsorb the workpiece 800 to be processed and can be lifted and lowered under the drive of the second lifting drive structure.

[0086] Optionally, the second gripping assembly 421 further includes a second clamping member 421b, which is mounted on the lower end of the second lifting drive structure and can be lifted and lowered under the drive of the second lifting drive structure. The second clamping member 421b can be a gripper cylinder, which can fix the workpiece 800 to be processed at the lower end of the second lifting drive structure.

[0087] Combination Figure 7 and Figure 9 In some embodiments, the frame includes a bottom frame 430, and a rotating mechanism 410 is disposed on the bottom frame 430, or the rotating mechanism 410 is disposed near the bottom frame 430.

[0088] For example, the bottom frame 430 includes at least two first rods 431, which extend along a first direction Y and are spaced apart along a second direction X. The rotating mechanism 410 is fixedly disposed on the upper side of the at least two first rods 431.

[0089] Optionally, the bottom frame 430 further includes a second rod 432 extending along a second direction X, with both ends of the second rod 432 connected to adjacent first rods 431. Preferably, two or more second rods 432 are spaced apart along a first direction Y.

[0090] Furthermore, when there are two or more rotating mechanisms 410, the two or more rotating mechanisms 410 are arranged along the second direction.

[0091] In some embodiments, the frame further includes a top frame 440, and a conveying mechanism 420 is disposed on the top frame 440. Exemplarily, the top frame 440 includes a third rod 441 located above the first rod 431, the third rod 441 extending along a second direction X, and a second transmission track 422 of the conveying mechanism 420 mounted on the third rod 441 and disposed along the second direction X.

[0092] Optionally, at least two third rods 441 are provided, and the at least two third rods 441 are arranged at intervals along the second direction X, and the second transmission track 422 is connected to the at least two third rods 441. Further, when at least two conveying mechanisms 420 are provided along the second direction X, each conveying mechanism 420 is provided with at least two third rods 441.

[0093] Optionally, the top frame 440 also includes two fourth rods 442 extending along a first direction. The two fourth rods 442 are respectively placed at both ends of the third rod 441, and the fourth rods 442 are perpendicularly fixed to the plurality of third rods 441.

[0094] Optionally, the top frame 440 also includes a plurality of diagonal braces 443, which are inclined and have their downward inclined end fixedly connected to the vertical column in the frame, and their upward inclined end fixedly connected to the third rod 441 and / or the fourth rod 442, thereby providing support for the third rod 441 and / or the fourth rod 442.

[0095] Optionally, multiple third rods 441 and multiple fourth rods 442 are combined to form a rectangular frame structure. Four diagonal braces 443 are placed at the four corners of the rectangular frame structure and fixedly connected to their respective corners. This makes the top frame 440 more stable.

[0096] The number of printing devices in this embodiment can be one or two.

[0097] When the number of printing devices is one (reference) Figure 1 When the printing device simultaneously meets the double-sided printing requirements of the workpiece 800, the printing device and the flipping device 400 are arranged along the first direction Y. The conveying mechanism 420 is used to transfer the workpiece 800 on the printing device to the rotating mechanism 410, and to transfer the workpiece 800 on the rotating mechanism 410 to the printing device. That is, after the conveying mechanism 420 removes the workpiece 800 in the printing device and flips it, it sends the workpiece 800 back to the printing device for reverse printing.

[0098] When there are two printing devices, the two printing devices are arranged along the first direction Y, and the flipping device 400 is located between the two printing devices. One printing device is used to print one side of the workpiece 800, and the other printing device is used to print the other side of the workpiece 800. The conveying mechanism 420 is used to transfer the workpiece 800 on one of the printing devices to the rotating mechanism 410, and to transfer the workpiece 800 on the rotating mechanism 410 to the other printing device. That is, after the conveying mechanism 420 removes the workpiece 800 from one of the printing devices and reverses it, it sends the workpiece 800 to the other printing device for reverse printing.
