Description

Technical Field

[0001] This invention relates to the field of printing technology, and more specifically, to an inkjet printing robot. Background Technology

[0002] Inkjet printing robots are automated equipment that combines the mobility of industrial robots with inkjet printing technology. Their core function is to break through the limitations of traditional planar printing in terms of scenarios and shapes, enabling flexible printing operations on non-planar, irregularly shaped, large-size, customized, and high-precision parts. At the same time, they adapt to the automation and continuous production needs of industrial production lines, replacing the shortcomings of manual printing and traditional special-purpose printing equipment.

[0003] According to announcement number CN118478594A, a light-curing inkjet printing device and inkjet printing method are disclosed, including a printer head and a robotic arm. The printer head is connected to the robotic arm and can move under the drive of the robotic arm to print at the target position. The air extraction device is connected to the inner cavity of the sealing cover through a gas channel to draw the gas in the sealing cover into the gas channel.

[0004] According to the aforementioned patent, although the gas generated by inkjet printing can be adsorbed by the air extraction device, there is still a significant problem: the curing lamp is fixed on both sides during the curing process, so the curing effect is better when printing on vertical surfaces, but worse when printing on other inclined surfaces. When the curing lamp is installed at an angle, the curing effect is better when printing on inclined surfaces, but worse when printing on vertical surfaces. Therefore, the ideal design should allow the lamp to swing back and forth during the curing process to achieve curing on different surfaces, so that it can cure not only vertical surfaces but also inclined surfaces.

[0005] Based on this, the present invention discloses an inkjet printing robot. Summary of the Invention

[0006] To address the problem mentioned in the background art that it is not easy to perform curing operations on inkjet-printed workpieces with different surfaces, the present invention provides an inkjet printing robot, which includes an inkjet printing robot body, an inkjet head disposed at the output end of the inkjet printing robot body, and a workpiece conveyor belt disposed on one side of the inkjet printing robot body. In this technical solution, in order to enable the robot to cure different surfaces of the inkjet-printed workpiece, the curing equipment needs to be able to deflect up and down, so a deflectable structure is needed as a basis. As a further improvement to this technical solution, an auxiliary drying component is provided on the side of the inkjet printing robot body near the inkjet head of the workpiece. A rotating rod connected by a bearing is provided on the surface of the fixed frame. An adjustment auxiliary frame is fixedly connected on the surface of the rotating rod. A matching movable groove is opened on the side of the movable ring near the adjustment auxiliary frame. A UV curing unit is provided on the side of the adjustment auxiliary frame away from the fixed frame. A movable rotating gear is fixedly connected at the end of the fixed frame. The movable rotating gear and the adjustment auxiliary frame are arranged parallel to each other on the surface of the fixed frame.

[0007] Based on this, a driving base is needed to facilitate the deflection and solidification operation; The auxiliary drying assembly includes a fixed plate disposed at one end of the inkjet head, and the fixed plate is fixedly connected to one end of the inkjet head. A movable ring is provided at one end of the fixed plate and is sleeved on the outside of the inkjet head. An electric push rod is installed at the top of the fixed plate and the electric push rods are symmetrically distributed at the top of the fixed plate. The output end of the electric push rod is slidably connected to the end of the movable ring.

[0008] In another technical solution, in order to prevent ink from dripping after inkjet printing, a processing structure is needed to clean the ink.

[0009] The anti-drip cleaning assembly includes a fixed protective frame disposed on one side of the inkjet head, and the fixed protective frame is fixedly connected to one side of the inkjet head. One end of the fixed protective frame is provided with a through-connected vertical toothed plate, and the end of the vertical toothed plate is fixedly connected to a movable ring. The interior of the fixed protective frame is provided with a rotating shaft connected by a bearing. The surface of the rotating shaft is provided with a meshing rotating gear. The end of the fixed protective frame away from the vertical toothed plate is provided with a through-connected rotating shaft. A bevel gear set is meshed between the rotating shaft and the rotating shaft. The bottom end of the rotating shaft is provided with a fixedly connected rotating plate, and one end of the rotating plate is provided with an adsorption element.

[0010] In the third solution, in order to achieve multiple cleanings of ink to prevent dripping, a collection structure needs to be set at one end of the anti-drip cleaning component to process the cleaned ink and prevent excessive adsorption from affecting subsequent cleaning.

[0011] One end of the anti-drip cleaning component is provided with a scraping and collecting mechanism. The scraping and collecting mechanism includes a collection groove at the bottom of the rotating plate, and the collection groove is fixedly connected to the rotating plate. The bottom of the collection groove is provided with a drain outlet for draining liquid. The top of the rotating plate is provided with a cleaning scraper, and the top of the cleaning scraper is provided with a fixedly connected vertical rod. The end of the vertical rod away from the cleaning scraper is provided with a rotating roller. The bottom end of the fixed protective frame near the rotating shaft is provided with a fixedly connected auxiliary guide plate. Sliding grooves are provided on both sides of the rotating plate. An auxiliary slider is slidably connected inside the sliding groove, and one end of the auxiliary slider is fixedly connected to the cleaning scraper. A limiting spring connected to the sliding groove is provided on one side of the auxiliary slider.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this inkjet printing robot, curing operations at different angles are achieved. By activating an electric push rod, the movable ring moves up and down, connecting the movable rotating gear with the arc-shaped toothed plate during movement. This allows the UV curing unit to deflect back and forth, enabling curing operations at different angles. Furthermore, with the addition of an adjusting rod and an inclined auxiliary groove, the rotation of the movable ring is effectively achieved. As the movable ring rotates, the UV curing unit can rotate back and forth, increasing the curing area and solving the problem of inkjet printed patterns easily becoming chaotic when the curing angle of the UV curing unit is fixed.

[0013] 2. In this inkjet printing robot, the vertical toothed plate moves back and forth as the movable ring moves up and down, thereby enabling the meshing rotating gear connected on one side to rotate back and forth. The rotating shaft connected to the robot enables the rotation of the bevel gear set. Furthermore, the rotating shaft connects the rotating plate and the adsorption component to rotate at the bottom of the inkjet head, achieving rapid ink adsorption and preventing dripping that could affect the processing environment.

[0014] 3. In this inkjet printing robot, the cleaning scraper, which rotates synchronously during the rotation of the rotating plate, can be guided by the vertical rod connected to the top, the rotating roller, and the auxiliary guide plate. This enables the cleaning scraper to move and scrape, effectively treating the adsorbed ink and preventing excessive adsorption inside the adsorption component, which would result in excessive residue during subsequent cleaning. Therefore, the inkjet head will not be contaminated by ink dripping during multiple inkjet printing processes. Attached Figure Description

[0018] 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, and 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.

[0019] Existing inkjet printing robots require a solution that enables curing at different angles during the curing process after inkjet printing.

[0020] Therefore, the present invention provides an inkjet printing robot, see [link to relevant documentation]. Figure 1 As shown, it includes an inkjet printing robot body 1, an inkjet head 2 disposed at the output end of the inkjet printing robot body 1, and a workpiece conveyor belt 3 disposed on one side of the inkjet printing robot body 1.

[0021] In order to enable the inkjet printing robot to process workpieces in an assembly line manner, an assembly line conveyor method is required. Specifically, a drive motor is installed on one side of the workpiece conveyor belt 3, and the main body 1 of the inkjet printing robot is installed at one end of the workpiece conveyor belt 3.

[0022] Reference Figures 2-5 As shown, in order to achieve curing operations that do not fix the same direction and achieve curing at different angles, a deflectable structure is needed as a basis. Therefore, an auxiliary drying component 4 is provided on the side of the inkjet printing robot body 1 near the inkjet head 2. The rotating rod 46 is provided with an adjustment auxiliary frame 47 fixedly connected to it, and the movable ring 42 is provided with a matching movable groove on the side of the adjustment auxiliary frame 47. A UV curing unit 48 is provided on the side of the adjustment auxiliary frame 47 away from the fixed frame 45. The end of the fixed frame 45 is provided with a movable rotating gear 49 fixedly connected to it, and the movable rotating gear 49 and the adjustment auxiliary frame 47 are respectively arranged parallel to each other on the surface of the fixed frame 45.

[0023] During operation, the movable ring 42 moves on the surface of the inkjet head 2, and synchronously moves the movable rotating gear 49. As the movable rotating gear 49 moves, it rotates through the meshing arc-shaped toothed plate 44. The rotation of the movable rotating gear 49 synchronously rotates the connected rotating rod 46, which in turn rotates the connected adjustment auxiliary frame 47. This adjustment auxiliary frame 47 deflects the UV curing unit 48 at one end, allowing adjustment of the curing angle. This enables the curing of UV curing units at different angles. The inkjet-printed pattern is cured, enabling the inkjet printing robot to perform inkjet printing operations at different angles to achieve uniform curing. Compared to the fixed UV curing unit 48, it can cure workpieces printed at different angles. Conversely, when the movable ring 42 moves upward, the movable rotating gear 49 rotates in the opposite direction through the arc-shaped toothed plate 44, which in turn rotates the rotating rod 46 in the opposite direction. It can also realize the opposite rotation of the adjustment auxiliary frame 47 and the UV curing unit 48, thereby enabling reciprocating curing at different angles and completing the rapid curing of the workpiece after inkjet printing.

[0024] The bottom end of the arc-shaped toothed plate 44 is inclined, so that when the movable ring 42 rotates through the inclined auxiliary groove 402, the internal fixed frame 45, rotating rod 46 and adjusting auxiliary frame 47 can avoid interference with the arc-shaped toothed plate 44.

[0025] Furthermore, refer to Figure 2 and Figure 3 As shown, in order to realize the up and down movement of the movable ring 42, a control basis is required. Therefore, an electric push rod 43 is installed at the top of the fixed plate 41. By activating the electric push rod 43, the output end of the electric push rod 43 can push the movable ring 42 downward. Since the output end of the electric push rod 43 and the movable ring 42 are slidably connected, the electric push rod 43 can avoid interference when the movable ring 42 rotates during the up and down movement. It can also synchronously move the connected adjustment auxiliary frame 47, UV curing unit 48 and movable rotating gear 49, and realize the above-mentioned continuous oscillating curing operation. Therefore, the electric push rod 43 can serve as the control basis for the movable ring 42 and realize the up and down movement of the movable ring 42.

[0026] Among them, reference Figure 4 and Figure 5 As shown, a synchronous rotation assembly 40 is provided at one end of the movable ring 42 near the arc-shaped toothed plate 44. The synchronous rotation assembly 40 includes an adjusting rod 401 disposed on one side of the arc-shaped toothed plate 44, and the adjusting rod 401 is fixedly connected to the arc-shaped toothed plate 44. An inclined auxiliary groove 402 matching the adjusting rod 401 is provided inside the movable ring 42. A stabilizing rod 403 is provided at one end of the arc-shaped toothed plate 44 away from the adjusting rod 401, and the stabilizing rod 403 is fixedly connected to the arc-shaped toothed plate 44 and to the inkjet head 2.

[0027] During operation, the arc-shaped toothed plate 44 is fixedly connected to the inkjet head 2 through the stabilizing rod 403. Therefore, when the movable ring 42 moves up and down, the arc-shaped toothed plate 44 is fixedly set and will not move. At the same time, the end of the arc-shaped toothed plate 44 away from the stabilizing rod 403 is provided with an adjusting rod 401 that is fixedly connected. An inclined auxiliary groove 402 is provided inside the movable ring 42, and the adjusting rod 401 and the inclined auxiliary groove 402 are movably connected. Simultaneously, when the movable ring 42 is not moving downwards, the adjusting rod 401 is at the lowest end of the inclined auxiliary groove 402. As the movable ring 42 moves downwards, the inclined auxiliary groove 402 moves synchronously. Since the inclined auxiliary groove 402 is inclined, and the adjusting rod 401 and the arc-shaped toothed plate 44 are fixed, the movable ring 42 can rotate at the output end of the electric push rod 43 by being guided by the inclined auxiliary groove 402 when it moves downwards. Therefore, during the oscillating curing process, the UV curer 48 can also achieve the rotation of the movable ring 42, so that during the curing process, it can not only achieve oscillating deflection curing, but also rotation curing, increasing the curing area. Therefore, the UV curer 48 can achieve the curing of inkjet printed patterns at different angles.

[0028] In order to prevent ink from dripping after inkjet printing, a process structure is needed to clean up the ink.

[0029] Reference Figure 6 , Figure 7 and Figure 8 Specifically, after inkjet printing, ink drips from the bottom of the inkjet head 2. Therefore, an anti-drip structure is needed, which means a cleaning device is added to the bottom of the inkjet head 2. Thus, an anti-drip cleaning component 5 is provided at the bottom of the auxiliary drying component 4. The anti-drip cleaning component 5 includes a fixed protective frame 51 on one side of the inkjet head 2, and the fixed protective frame 51 is fixedly connected to one side of the inkjet head 2. A vertical toothed plate 52 is provided through one end of the fixed protective frame 51, and the end of the vertical toothed plate 52 is fixedly connected to the movable ring 42. The interior of the fixed protective frame 51 is provided with a bearing-connected... The rotating shaft 53 is connected to the fixed protective frame 51, which is away from the vertical toothed plate 52. A rotating shaft 55 is connected through the rotating shaft 53. A bevel gear set 56 is meshed between the rotating shaft 55 and the rotating shaft 53. A rotating plate 57 is fixedly connected to the bottom of the rotating shaft 55. An adsorption element 58 is provided at one end of the rotating plate 57. It can be seen that when the movable ring 42 moves up and down synchronously, it can move the vertical toothed plate 52 on one side synchronously. Thus, the vertical toothed plate 52 moves while the meshing rotating gear 54 on one side rotates.

[0030] As the meshing gear 54 rotates, it synchronously rotates the rotating shaft 53. The rotating shaft 53, in turn, rotates the bevel gear set 56 connected to one side. Simultaneously, the rotation of the bevel gear set 56 rotates the rotating shaft 55 connected to the other end. The rotation of the rotating shaft 55, in turn, synchronously rotates the rotating plate 57 connected to the bottom end. The adsorption element 58, located at one end of the rotating plate 57, rotates synchronously and adsorbs any dripping ink during rotation, thus completely preventing dripping. The adsorption element 58 is made of nylon fiber felt and is compatible with water-based, solvent-based, and UV inks. The ink is suitable for scenarios where the robot end effector moves frequently. It is fixed to the end of the rotating plate 57 by a high-temperature resistant clip. It can be cleaned by rinsing with a high-temperature solvent. It can also prevent the ink from falling off due to friction after installation. The movable ring 42 can move up and down by an electric push rod 43. While moving up and down, it can also move up and down the vertical toothed plate 52, thereby rotating the meshing rotating gear 54 on one side in both directions. The distance that the vertical toothed plate 52 moves down can make the meshing rotating gear 54 rotate 360°. After rotation, the rotating shaft 53 rotates in both directions simultaneously, realizing the rotation cleaning of the rotating plate 57. This allows for the rapid adsorption of ink at the bottom of the inkjet head 2, thus achieving rapid ink removal.

[0031] Furthermore, refer to Figure 8 , Figure 9 , Figure 10 and Figure 11 To achieve multiple ink cleaning cycles and prevent dripping, a collection structure needs to be installed at one end of the anti-drip cleaning component 5 to process the cleaned ink and prevent excessive adsorption from affecting subsequent cleaning. Therefore, a scraping and collecting mechanism 6 is provided at one end of the anti-drip cleaning component 5. The scraping and collecting mechanism 6 includes a collection groove 61 located at the bottom of the rotating plate 57, and the collection groove 61 is fixedly connected to the rotating plate 57. A drain outlet 62 for draining liquid is provided at the bottom of the collection groove 61, and a cleaning scraper 6 is provided at the top of the rotating plate 57. 3. A vertical rod 64 is fixedly connected to the top of the cleaning scraper 63. A rotating roller 65 is provided at the end of the vertical rod 64 away from the cleaning scraper 63. An auxiliary guide plate 66 is fixedly connected to the bottom of the fixed protective frame 51 near the rotating shaft 55. Sliding grooves 67 are provided on both sides of the rotating plate 57. An auxiliary slider 68 is slidably connected inside the sliding groove 67. One end of the auxiliary slider 68 is fixedly connected to the cleaning scraper 63. A limiting spring 69 connected to the sliding groove 67 is provided on one side of the auxiliary slider 68.

[0032] The cleaning scraper 63 is shaped like a "U".

[0033] During operation, as the rotating plate 57 rotates and absorbs ink through the suction member 58 at its top, the connected cleaning scraper 63 rotates simultaneously. The rotating plate 57 can rotate 360° via the bevel gear set 56 to completely clean the inkjet head 2. After rotating 180°, the rotating plate 57 separates from the inkjet head 2 after cleaning. At this point, the absorbed ink adheres to the surface of the suction member 58. Upon continued rotation, the ink contacts the auxiliary guide plate 66 via the rotating roller 65 at the top of the vertical rod 64. The auxiliary guide plate 66 is inclined at the bottom of the fixed protective frame 51, allowing it to guide the rotating roller 65. The vertical rod 64 and the cleaning scraper 63 can move synchronously along the auxiliary guide plate 66. At this time, the cleaning scraper 63 can slide inside the sliding groove 67 through the auxiliary slider 68. During the sliding process, it will squeeze the limiting spring 69 set inside. As the cleaning scraper 63 moves, it can scrape the surface of the adsorption element 58, so that the adsorbed ink can overflow through the squeeze and drip along both sides of the rotating plate 57. It can then be collected through the collection groove 61 set at the bottom of the rotating plate 57, which can avoid the need for manual processing of the adsorption element 58 multiple times. The ink inside the collection groove 61 can be discharged through the discharge port 62. Furthermore, as the rotating shaft 55 rotates, the rotating roller 65 can separate from the auxiliary guide plate 66, so that the limiting spring 69 inside the rotating plate 57 can be restricted, and thus a reset can occur. After the reset, the cleaning scraper 63 can be reset to the initial position, which will not affect the ink adsorption process during rotation. Therefore, the inkjet head 2 will not be contaminated by ink dripping during multiple inkjet printing processes.

[0034] Meanwhile, an extraction port connected to a vacuum pump, as described in the comparative patent, is also provided at one end of the inkjet head 2. This port is not shown in the figure and can extract odors during inkjet printing, thereby improving the processing environment.

[0035] In summary, this solution enables multi-angle curing of inkjet-printed patterns through the swinging rotation and deflection curing of the auxiliary drying component 4, and the rotational cleaning of the anti-drip cleaning component 5 to remove ink from the bottom, preventing dripping. It not only achieves the back-and-forth deflection and swinging rotation of the UV curer 48, enabling rapid curing of inkjet-printed patterns at different angles, but also achieves rapid cleaning of the inkjet head 2 and prevention of ink accumulation after inkjet printing through the coordinated cooperation of the anti-drip cleaning component 5 and the scraping and collecting mechanism 6, solving the problem of poor working environment caused by ink dripping, and can also achieve multiple cycles of autonomous cleaning.
