Description

Technical Field

[0001] This application relates to the field of printing technology, and in particular to a printer and printhead assembly. Background Technology

[0002] With the development of printing technology, various types of printing devices have emerged, including but not limited to UV printers and inkjet printers. UV printers, in particular, are large and expensive. The UV printhead is the core functional component of a UV printer, accounting for more than half of the total cost, and is typically fixed to the crossbeam movement mechanism and cannot be disassembled. However, most printing malfunctions are concentrated in the UV printhead. When the UV printhead malfunctions, it is necessary to disassemble numerous related parts such as the ink lines, printing movement components, and belts, making disassembly and repair cumbersome and inefficient.

[0015] In one embodiment, the quick-release assembly further includes an elastic clamping component mounted on the bracket, the elastic clamping component being used to clamp the first adapter circuit board onto the bracket.

[0016] In one embodiment, the elastic clamping assembly includes a spring and a clamping member; a third movable hole is formed on the first adapter circuit board, which extends horizontally along a direction perpendicular to the insertion direction S, and the extension direction of the third movable hole is parallel to the extension direction of the first movable hole; the clamping member passes through the third movable hole and is connected to the bracket; the spring is sleeved on the clamping member, and the opposite ends of the spring are disposed between the clamping member and the first adapter circuit board.

[0017] In one embodiment, the ink inlet of the ink cartridge is provided with a first docking connector, and the printing moving assembly is provided with a second docking connector for connecting to the ink cartridge assembly. The first docking connector and the second docking connector are detachably connected. When the first docking connector and the second docking connector are separated from each other, both the first docking connector and the second docking connector are in a closed state. When the first docking connector and the second docking connector are connected to each other, the first docking connector and the second docking connector are interconnected.

[0018] In one embodiment, the first docking joint includes a first insertion tube and a first elastic element, a push rod, and a first piston head disposed inside the first insertion tube; the first piston head is connected to the first insertion tube through the first elastic element, and the first piston head is also connected to a first end of the push rod; the working position of the first piston head includes a first sealing position for sealing the first insertion tube and a first unsealing position for opening the first insertion tube.

Detailed Implementation

[0044] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0045] It should be noted that, in this embodiment, a UV printhead refers to a printer printhead that uses ultraviolet (UV) curing ink, which can print on various materials. A UV printer refers to a printer that uses ultraviolet (UV) curing ink, which can print on various materials.

[0046] It should be noted that the detachable connection in this embodiment can refer to a direct detachable connection between two components, that is, there is no intermediate element between the two components; or it can refer to an indirect detachable connection between two components, that is, at least one intermediate element is allowed between the two components to realize the detachable connection between the two components.

[0047] See Figures 1 to 7This application provides a printhead device according to one embodiment, which includes a quick-release assembly 10 and a printing moving assembly 20. The quick-release assembly 10 is detachably mounted on the printing moving assembly 20. The printing moving assembly includes a moving base 21 and a first electrical connection connector 22 disposed on the moving base 21. The moving base is movably mounted on the crossbeam movement mechanism of the printer, and the first electrical connection connector 22 is electrically connected to a controller. Optionally, the controller includes an electrical connector 30. The electrical connector includes, but is not limited to, a transmission line for transmitting electrical signals, such as a flexible flat cable. Furthermore, the electrical connector 30 is electrically connected to the first electrical connection connector 22. The connection method between the first electrical connection connector 22 and the electrical connector 30 includes, but is not limited to, welding, snap-fit, connection and fixation using various conductive fasteners such as pins, rivets, and screws, connection and fixation using conductive tape, or connection and fixation using conductive adhesive, etc., which can be flexibly adjusted and set according to actual needs.

[0048] Specifically, the quick-release assembly 10 includes: a bracket 11, a UV printhead 12, an ink cartridge 13, and a second electrical connector 14. The bracket 11 is detachably mounted on the printing moving assembly 20. The UV printhead 12 is mounted on the bracket 11. When the bracket 11 is mounted on the printing moving assembly 20, the printing moving assembly 20 can drive the bracket 11 to move, thereby driving the UV printhead 12 mounted on the bracket 11 to complete the printing work of the UV printhead 12.

[0049] Furthermore, the ink sac 13 is mounted on the bracket 11, and the ink inlet of the ink sac 13 is detachably connected to the ink cartridge assembly, while the ink outlet of the ink sac 13 is connected to the UV printhead 12. Specifically, when the ink inlet is connected to the ink cartridge assembly, the ink sac 13 can receive the ink output by the ink cartridge assembly.

[0050] Furthermore, the second electrical connector 14 is electrically connected to the UV printhead 12, and is also detachably connected to the first electrical connector 22. Specifically, when the second electrical connector 14 is connected to the first electrical connector 22, the second electrical connector 14 is electrically connected to the controller through the first electrical connector 22, thereby enabling the UV printhead 12 to be electrically connected to the controller and operate under the control of the controller, such as performing printing operations. Conversely, when the second electrical connector 14 and the first electrical connector 22 are separated, the electrical connection between the second electrical connector 14 and the first electrical connector 22 is disconnected, as is the mechanical connection, allowing the quick-release assembly to be detached from the printing moving assembly.

[0051] The aforementioned quick-release assembly 10 includes a printing moving assembly 20, which has a moving base 21 and a first electrical connection connector 22 electrically connected to the controller. The UV printhead 12, ink cartridge 13, and second electrical connection connector 14 are mounted on a bracket 11, and the bracket 11 is detachably mounted on the printing moving assembly 20, so that the quick-release assembly 10 is detachably connected to the printing moving assembly 20. In addition, the ink inlet of the ink cartridge 13 is detachably connected to the ink cartridge assembly, and the second electrical connection connector 14 is detachably connected to the first electrical connection connector 22. In this way, when the UV printhead 12 malfunctions and needs maintenance, the ink inlet and ink cartridge assembly are disconnected, and the second electrical connection connector 14 and the first electrical connection connector 22 are disconnected, and then the quick-release assembly 10 is removed from the printing moving assembly 20, so that the malfunctioning UV printhead 12 can be maintained. Compared with the prior art, the disassembly workload is smaller, maintenance is easier, and maintenance efficiency is higher.

[0052] Please see Figures 1 to 3 In one embodiment, the printing moving assembly 20 includes a movable base 21 with a receiving groove 211. A bracket 11 is slidably inserted into the receiving groove 211. Once the bracket 11 is inserted into the receiving groove 211, it is fixedly connected to the printing moving assembly 20, specifically to the movable base 21. Thus, because the bracket 11 is inserted into the receiving groove 211 in a sliding manner, it facilitates the installation and removal of the quick-release assembly 10 on the printing assembly. Furthermore, after the quick-release assembly 10 is installed, it is located inside the receiving groove 211, and the bracket 11 is fixedly connected to the printing moving assembly 20, thereby achieving stable mounting on the printing moving assembly 20.

[0053] Please see Figures 1 to 3 In one embodiment, the bracket 11 is provided with a first snap-fit ​​portion 111, which is used to engage with a second snap-fit ​​portion 212 on the printing moving assembly 20. Specifically, the second snap-fit ​​portion 212 is disposed on the movable base 21. When the bracket 11 is inserted into the receiving groove 211, the first snap-fit ​​portion 111 and the second snap-fit ​​portion 212 engage with each other to connect and fix the bracket 11 to the printing moving assembly 20. In this way, by sliding the quick-release assembly 10 into the receiving groove 211 of the printing moving assembly 20, and after it is inserted into place, the first snap-fit ​​portion 111 and the second snap-fit ​​portion 212 engage with each other to achieve the connection and fixation of the bracket 11 and the printing moving assembly 20. Compared with the screw connection method, this eliminates the tedious steps of removing and installing screws, which can greatly improve the disassembly and assembly efficiency and user experience of the quick-release assembly 10.

[0054] Specifically, the first latching portion 111 includes a first pressing member 1111 connected to the outer periphery of the bracket 11 and pressable, and a first holding block 1112 connected to the first pressing member 1111. The first latching portion 111 may be located on the top wall, bottom wall, or left and right side walls of the bracket 11, etc., and is not specifically limited here. The second latching portion 212 is specifically provided, for example, on the wall of the insertion port of the receiving groove 211 for insertion of the bracket 11. Optionally, the insertion port is formed on one side of the receiving groove 211, so that the quick-release assembly 10 is inserted into the receiving groove 211 from one side of the receiving groove 211 in a horizontal direction, and after being inserted into the receiving groove 211, it is stably supported by the printing moving assembly 20. Furthermore, the first pressing member 1111 includes, but is not limited to, a pressing plate, pressing strip, or pressing block arranged at an angle to the outer wall of the bracket 11, with one end of the first pressing member 1111 connected to the bracket 11 and the other end being a free end. When the free end is pressed, the first pressing member 1111 can drive the first holding block 1112 to move and separate from the second locking part 212, thereby allowing the quick-release assembly 10 to be pulled out of the printing moving assembly 20, achieving quick release. Thus, it is evident that not only can the quick-release assembly 10 be stably and quickly assembled onto the printing moving assembly 20, but it can also be easily and quickly removed from the printing moving assembly 20, thereby improving the maintenance efficiency of the UV printhead 12.

[0055] Optionally, the number of the first latching part 111 and the second latching part 212 may be one, two or other, for example, without limitation, and can be flexibly adjusted and set according to actual needs.

[0056] Of course, in some alternative solutions, the bracket 11 is not limited to having a first snap-fit ​​part 111, and the printing moving component 20 does not need to have a second snap-fit ​​part 212. Instead, after the bracket 11 is inserted into the receiving groove 211, various fasteners such as positioning pins, screws, straps, and ropes are used to connect and fix the quick-release component 10 and the printing moving component 20. The specific selection and setting can be flexibly selected according to actual needs, and are not limited here.

[0057] Please see Figure 1 , Figure 3 , Figure 5 , Figure 6 , Figure 8 and Figure 9In one embodiment, the first electrical connector 22 includes a first insertion portion 221. The second electrical connector 14 includes a second insertion portion 141. The second insertion portion 141 is inserted into the first insertion portion 221. The insertion direction of the second insertion portion 141 is the same as the insertion direction S of the bracket 11 into the receiving groove 211. When the bracket 11 is inserted into the receiving groove 211, the second insertion portion 141 is simultaneously inserted into the first insertion portion 221. Thus, when the quick-release assembly 10 is pulled out from inside the receiving groove 211, the second plug-in part 141 will simultaneously separate from the first plug-in part 221, thereby disconnecting the second electrical connector 14 from the first electrical connector 22, and thus disconnecting the second electrical connector 14 from the controller, enabling rapid electrical disconnection. Conversely, when the quick-release assembly 10 is inserted into the receiving groove 211 through the insertion port, the second plug-in part 141 will simultaneously insert into the first plug-in part 221, thereby electrically connecting the second electrical connector 14 to the first electrical connector 22, and thus connecting the second electrical connector 14 to the controller, demonstrating rapid electrical connection.

[0058] It should be noted that the specific configuration of the second connector 141 and the first connector 221 can vary, including but not limited to the mating configuration of the gold finger 1411 and the slot 2211, the mating configuration of the USB connector and the USB interface, the mating configuration of the electrical pin and the electrical socket, etc. These can be flexibly adjusted and configured according to actual needs, and will not be simplified here. In one example, one of the second connector 141 and the first connector 221 may have a gold finger 1411, and the other may have a corresponding slot 2211 for mating with the gold finger 1411. Inserting the gold finger 1411 into the slot 2211 enables the second connector 141 and the first connector 221 to connect and communicate. Conversely, when the gold finger 1411 is pulled out of the slot 2211, the second connector 141 and the first connector 221 are separated. In another example, one of the second connector 141 and the first connector 221 may be provided with a USB connector, and the other may be provided with a USB interface that mates with the USB connector. Inserting the USB connector into the USB interface enables the second connector 141 and the first connector 221 to connect and communicate. Conversely, pulling the USB connector out of the USB interface separates the second connector 141 from the first connector 221.

[0059] In this embodiment, to save space and cost, the second plug-in portion 141 and the first plug-in portion 221 are respectively provided with gold fingers 1411 and slots 2211, and are mutually plugged in. Furthermore, the mutual plugging of the gold fingers 1411 and slots 2211 achieves the electrical connection between the second electrical connector 14 and the first electrical connector 22, avoiding the cumbersome and inconvenient process of plugging and unplugging the wiring harness when replacing the UV nozzle 12 in related technologies.

[0060] Please see Figure 1 , Figure 5 and Figure 7 In one embodiment, the bracket 11 has sliding grooves 112 extending along the insertion direction S of the quick-release assembly 10 on opposite sides. The two sliding grooves 112 are used to slide and engage with protrusions 2111 extending along the insertion direction S on opposite inner walls of the receiving groove 211. Thus, during the assembly and disassembly of the quick-release assembly 10, the sliding grooves 112 on opposite sides of the bracket 11 slide and engage with the protrusions 2111 on opposite inner walls of the receiving groove 211. The protrusions 2111 provide support and guidance for the sliding movement of the bracket 11 within the receiving groove 211, enabling not only stable insertion of the quick-release assembly 10 but also ensuring that the second insertion part 141 can normally and stably engage with the first insertion part 221 during the insertion of the quick-release assembly 10 into the receiving groove 211.

[0061] Based on the aforementioned embodiments, in order to improve the operational stability and operational direction accuracy of the quick-release assembly 10, the outer peripheral wall of the bracket 11, specifically the bottom wall, side wall and top wall of the bracket 11, is adapted to the shape of the inner peripheral wall of the receiving groove 211, so that the bracket 11 can slide and cooperate with the inner peripheral wall of the receiving groove 211 during operation inside the receiving groove 211.

[0062] Based on the aforementioned embodiment, a clearance opening is formed on the bottom wall of the receiving groove 211, which corresponds to the position of the UV printhead 12. The UV printhead 12 is exposed through the clearance opening, so that the UV printhead 12 can carry out printing work normally and can prevent the printing moving component 20 from blocking the UV printhead 12 and affecting the normal working performance of the UV printhead 12.

[0063] Please see Figure 1 , Figure 3 , Figure 5 , Figure 6 and Figure 9In some specific embodiments, this embodiment specifically uses the example of the second insertion part 141 having a gold finger 1411 and the first insertion part 221 having a corresponding slot 2211 for insertion and mating with the gold finger 1411, but it is not limited to this. During the docking process between the second insertion part 141 and the first insertion part 221, there may be a misalignment to the left, right, up, or down, including but not limited to 0.1mm to 3mm, which may easily lead to docking failure, such as failure to insert smoothly, jamming during the insertion process, or failure to achieve a reliable electrical connection after insertion, etc.

[0064] Please see Figure 6 and Figure 9 Optionally, the opening wall of the slot 2211 is configured as a flared opening with a diameter that gradually decreases along the insertion direction of the gold finger 1411. In other words, the opening wall of the slot 2211 is provided with a first guide slope 2212 at an angle to the insertion direction of the gold finger 1411. Specifically, the left and right opposing opening walls and the top and bottom opposing opening walls of the slot 2211 are each provided with a first guide slope 2212. In this way, during the process of inserting the gold finger 1411 into the slot 2211 along the insertion direction, each first guide slope 2212 can play a guiding role. Regardless of whether there is a leftward, rightward, upward, or downward alignment deviation of the gold finger 1411, the gold finger 1411 can be accurately inserted and assembled into the slot 2211, ensuring normal and stable operation after docking and preventing defects such as unreliable electrical connection stability or even failure to dock due to misalignment.

[0065] Please see Figure 6 and Figure 9 In some embodiments, the edges of the end of the second insertion portion 141 are chamfered, specifically, all four edges of the end of the second insertion portion 141 are chamfered so that the outer diameter of the end of the second insertion portion 141 gradually decreases along the insertion direction. Specifically, each chamfer of the end of the second insertion portion 141 forms a second guide slope 1412, which is set at an angle to the insertion direction. In this way, during the process of inserting the gold finger 1411 into the slot 2211 along the insertion direction, the second guide slope 1412 plays a guiding role. Regardless of whether the gold finger 1411 has a leftward, rightward, upward, or downward alignment deviation, it can achieve accurate docking and insertion into the slot 2211, ensuring normal and stable operation after docking and preventing defects such as unreliable electrical connection stability or even failure to dock due to misalignment.

[0066] Please see Figure 6 and Figure 9Based on the aforementioned embodiments, the printing moving assembly 20 includes a moving base 21 with a receiving groove 211. A first electrical connector 22 is mounted on the outer wall of the moving base 21 using various fasteners such as pins, rivets, and bolts. A first through hole 213 corresponding to the position of the first insertion portion 221 is formed on the moving base 21, and the first insertion portion 221 is inserted into the first through hole 213, for example. Furthermore, a second insertion portion 141 can pass through the first through hole 213 and be inserted into the first insertion portion 221. Optionally, the end of the first through hole 213 facing the second insertion portion 141 is provided with a tapered hole whose diameter gradually decreases along the insertion direction. Specifically, the end of the first through hole 213 facing the second insertion portion 141 is, for example, provided with a third guide slope 2131 formed at an angle to the insertion direction of the gold finger 1411. Specifically, the first through hole 213 is, for example, a rectangular hole with a rectangular axial cross-section. The left and right opposite holes and the top and bottom opposite holes of the first through hole 213 are each provided with a third guide slope 2131. Thus, as the gold finger 1411 is inserted into the slot 2211 through the first through hole 213 along the insertion direction, each third guide slope 2131 first acts as a guide, providing initial calibration. Then, each first guide slope 2212 further acts as a guide, providing further calibration. This ensures that regardless of left, right, up, or down alignment deviations of the gold finger 1411, it can be accurately inserted and assembled into the slot 2211, guaranteeing normal and stable operation after alignment. This prevents defects such as unreliable electrical connection stability or even failure to align due to misalignment.

[0067] Please see Figure 1 , Figure 6 and Figure 9In one embodiment, the second electrical connector 14 further includes a first adapter circuit board 142 connected to the second insertion portion 141. The first adapter circuit board 142 is electrically connected to the UV nozzle 12. The first adapter circuit board 142 is horizontally floating on the bracket 11 perpendicular to the insertion direction S, and vertically floating on the bracket 11 perpendicular to the insertion direction S. Thus, regardless of whether the gold finger 1411 has a leftward, rightward, upward, or downward alignment deviation, since the first adapter circuit board 142 is horizontally floating along the insertion direction S and vertically floating along the insertion direction S on the bracket 11, during the mutual insertion of the second insertion part 141 and the first insertion part 221, the first adapter circuit board 142 can adjust its position horizontally floating along the insertion direction S and vertically floating along the insertion direction S. Ultimately, this ensures that the gold finger 1411 is accurately inserted and assembled into the slot 2211, guaranteeing normal and stable operation after docking and preventing defects such as unreliable electrical connection stability or even failure to dock due to misalignment.

[0068] In some embodiments, similar to the second electrical connector 14, the first electrical connector 22 further includes a second adapter circuit board 222 connected to the first plug portion 221, and the second adapter circuit board 222 is electrically connected to the electrical connector 30.

[0069] In one embodiment, a first movable hole 1421 is formed on the first adapter circuit board 142, extending horizontally along the insertion direction S. A first movable post 113 is movably disposed in the first movable hole 1421 on the bracket 11. Alternatively, a second movable hole can be formed on the bracket 11, extending horizontally along the insertion direction S, and a second movable post can be movably disposed in the second movable hole on the first adapter circuit board 142. Thus, the first movable post 113 passing through the first movable hole 1421, and / or the second movable post passing through the second movable hole, not only serves a positioning function, improving the installation and positioning accuracy of the first adapter circuit board 142 on the bracket 11, but also allows the first adapter circuit board 142 to float and adjust its position horizontally along the insertion direction S, achieving a good connection between the second insertion part 141 and the first insertion part 221.

[0070] Specifically, the first adapter circuit board 142 floats horizontally along a distance perpendicular to the insertion direction S, including but not limited to 0.1 mm to 3 mm.

[0071] In some embodiments, the first movable hole 1421 may include, but is not limited to, one or more, depending on actual needs. The first movable hole 1421 may include, but is not limited to, a slotted hole or a strip-shaped hole, etc. In addition, the first movable column 113 is provided corresponding to the first movable hole 1421. Furthermore, the first movable column 113 may include, but is not limited to, a column with a regular shape such as a circle, ellipse, or polygon in axial cross-section, or other irregular shapes, which may be adjusted and set according to actual needs.

[0072] It should be noted that the arrangement of the second movable hole and the second movable column is similar to that of the first movable hole 1421 and the first movable column 113, and will not be described again here.

[0073] Please see Figure 6 and Figure 9 In one embodiment, the quick-release assembly 10 further includes an elastic clamping assembly 15 mounted on the bracket 11. The elastic clamping assembly 15 is used to press the first adapter circuit board 142 onto the bracket 11. Thus, the elastic clamping assembly 15 presses the first adapter circuit board 142 onto the bracket 11, preventing the first adapter circuit board 142 from shaking up and down, and supporting the first adapter circuit board 142 and the second plug-in part 141 to float up and down under the pressure of the spring 151, satisfying the requirement that the first adapter circuit board 142 floats up and down along a direction perpendicular to the insertion direction S to adjust its position, thereby achieving good docking between the second plug-in part 141 and the first plug-in part 221.

[0074] In one embodiment, the elastic clamping assembly 15 includes a spring 151 and a clamping member 152. A third movable hole 1422 is formed on the first adapter circuit board 142, extending horizontally perpendicular to the insertion direction S. The extension direction of the third movable hole 1422 is parallel to the extension direction of the first movable hole 1421. The clamping member 152 passes through the third movable hole 1422 and is connected to the bracket 11. The spring 151 is sleeved on the clamping member 152, and the opposite ends of the spring 151 are located between the clamping member 152 and the first adapter circuit board 142. Thus, the clamping member 152 presses the spring 151 against the first adapter circuit board 142, resulting in good stability of the first adapter circuit board 142 and the ability to float and adjust its position in the vertical direction.

[0075] In some embodiments, the clamping member 152 includes, but is not limited to, a screw, bolt, or other similar device. Similar to the first movable hole 1421, the third movable hole 1422 includes, but is not limited to, a slotted hole or a strip-shaped hole. In this example, the clamping member 152 is specifically, for example, a screw, the diameter of which is larger than the diameter of the first movable post 113, thereby providing better positioning.

[0076] In some embodiments, the elastic clamping assembly 15 further includes a pad. One end of the spring 151 abuts against the first adapter circuit board 142, and the other end abuts against the head of the clamping member 152 via the pad. The pad enhances the support stability of the clamping member 152.

[0077] Please see Figures 11 to 14 as well as Figures 15 to 18 In one embodiment, the ink inlet of the ink cartridge 13 is provided with a first connector 16, and the printing moving assembly 20 is provided with a second connector 23 for connection with the ink cartridge assembly. The first connector 16 and the second connector 23 are detachably connected; when the first connector 16 and the second connector 23 are separated, both are in a closed state; when the first connector 16 and the second connector 23 are connected, they are interconnected. Thus, on the one hand, the detachable connection of the first connector 16 and the second connector 23 facilitates the disassembly and assembly of the quick-release assembly 10; on the other hand, when the first connector 16 and the second connector 23 are separated, both are in a closed state, thereby preventing the ink inside the quick-release assembly 10 from leaking out through the first connector 16, and preventing the ink inside the second connector 23 and the ink cartridge assembly from leaking out through the second connector 23.

[0078] In one embodiment, the first mating connector 16 includes a first insertion tube 161 and a first elastic element 162, a push rod 163, and a first piston head 164 disposed inside the first insertion tube 161. The first piston head 164 is connected to the first insertion tube 161 through the first elastic element 162, and the first piston head 164 is also connected to the first end of the push rod 163. The working positions of the first piston head 164 include a first sealing position for sealing the first insertion tube 161 and a first unsealing position for opening the first insertion tube 161.

[0079] Furthermore, the second mating connector 23 includes a second insertion tube 231 for insertion and mating with the first insertion tube 161, a second elastic element 232 disposed inside the second insertion tube 231, and a second piston head 233. The second piston head 233 is connected to the second insertion tube 231 through the second elastic element 232, and the working positions of the second piston head 233 include a second sealing position for sealing the second insertion tube 231 and a second unsealing position for opening the second insertion tube 231.

[0080] Please see Figure 17 and Figure 18When the first mating joint 16 and the second mating joint 23 are separated, the first piston head 164 seals the first insertion tube 161 under the elastic force of the first elastic element 162, and the second piston head 233 seals the second insertion tube 231 under the elastic force of the second elastic element 232.

[0081] Please see Figures 13 to 16 When the first mating joint 16 and the second mating joint 23 are connected to each other, the first insertion tube 161 and the second insertion tube 231 are inserted into each other, and the second end of the push rod 163 extends into the interior of the second insertion tube 231 and presses against the second piston head 233, so that the second piston head 233 moves to the second unsealing position and the first piston head 164 moves to the first unsealing position.

[0082] In one embodiment, a rubber stopper 234 is installed at the end of the second insertion tube 231 near the first insertion tube 161. When the second piston head 233 is in the second sealing position, the second piston head 233 abuts against the rubber stopper 234. When the first mating joint 16 and the second mating joint 23 are connected, the first insertion tube 161 is inserted into the second through hole of the rubber stopper 234 and is press-fitted into the second through hole. Thus, when the first mating joint 16 and the second mating joint 23 are connected, the first insertion tube 161 is inserted into the second through hole of the rubber stopper 234, resulting in good sealing at the joint between the first insertion tube 161 and the second insertion tube 231. When the first mating joint 16 and the second mating joint 23 are separated, the second piston head 233 abuts against the rubber stopper 234, which also ensures a tight seal.

[0083] In some embodiments, to improve sealing, at least one first sealing flange 2341 is formed on the inner wall of the second through hole, and the first sealing flange 2341 has good sealing performance when it abuts against the outer wall of the first insertion tube 161. Furthermore, at least one second sealing flange 2342 is formed on the outer wall of the rubber stopper 234, and the second sealing flange 2342 has good sealing performance when it abuts against the inner wall of the second insertion tube 231.

[0084] In some embodiments, the second mating connector 23 further includes a pressure ring 235 disposed inside the second insertion tube 231 and abutting against the end of the rubber plug 234 opposite to the second piston head 233. Optionally, the pressure ring 235 is, but not limited to, fixed to the inner wall of the second insertion tube 231 by ultrasonic welding or bonding, mainly providing reverse pressure to the rubber plug 234, so that the rubber plug 234 abuts tightly against the second piston head 233, ensuring sealing and preventing the rubber plug 234 from detaching from the second insertion tube 231.

[0085] Of course, in some alternative solutions, a rubber plug 234 may be installed at one end of the first insertion tube 161 near the second insertion tube 231, and the second insertion tube 231 may be inserted into the through hole of the rubber plug 234 of the first insertion tube 161.

[0086] Generally, neither the ink cartridge assembly nor the ink sac 13 is limited to one. As an example, there may be multiple ink cartridge assemblies and multiple ink sacs 13, the same number as the ink cartridge assemblies. Correspondingly, there may be multiple first connectors 16 and multiple second connectors 23. Each first connector 16 corresponds to each ink sac 13, and each second connector 23 corresponds to each ink cartridge assembly. Furthermore, each first connector 16 corresponds to each second connector 23.

[0087] Based on the foregoing embodiments, to facilitate the assembly and disassembly of the multiple first mating joints 16 and the multiple second mating joints 23, optionally, the printing moving assembly 20 is provided with a height-adjustable mounting base 24. All second mating joints 23 are mounted on the mounting base 24. The working positions of the mounting base 24 include a first height position and a second height position arranged sequentially along the lifting direction, with the second height position located above the first height position. Please refer to... Figure 15 and Figure 16 When the mounting base 24 is in the first height position, each of the second mating joints 23 is connected to each of the first mating joints 16 accordingly; please refer to Figure 17 and Figure 18 When the mounting base 24 is in the second height position, each of the second mating joints 23 and each of the first mating joints 16 are separated.

[0088] Specifically, the mounting base 24 is provided with a first slot 241 and a second slot 242 arranged sequentially along the lifting direction, and the printing moving component 20 is provided with a buckle 25 that can engage with the first slot 241 or the second slot 242. When the mounting base 24 moves to the first height position, the buckle 25 engages and is fixed in the first slot 241; when the mounting base 24 moves to the second height position, the buckle 25 engages and is fixed in the second slot 242.

[0089] Please see Figure 10 In some embodiments, the printing moving assembly 20 further includes a plurality of ink tubes 26 for connecting each of the second docking connectors 23 to the ink cartridge assembly. The plurality of ink tubes 26 are arranged in a row and secured together by a tube slot 27. In addition, the electrical connectors 30 include, but are not limited to, flexible flat cables, which facilitate the connection of the second adapter circuit board 222 to the controller. Furthermore, the printing moving assembly 20 also includes a fan 28, an air guide 291, and a UV lamp assembly 292 mounted on the moving base 21.

[0090] Please see Figures 1 to 3 In some embodiments, a printer includes the printhead assembly of any of the above embodiments, a controller, and an ink cartridge assembly. The controller is electrically connected to the UV printhead 12, and the ink cartridge assembly is detachably connected to the ink inlet of the ink sac 13.

[0091] The printer described above includes a printing moving assembly 20, which has a moving base 21 and a first electrical connection connector 22 electrically connected to the controller. The UV printhead 12, ink cartridge 13, and second electrical connection connector 14 are mounted on a bracket 11, and the bracket 11 is detachably mounted on the printing moving assembly 20. Thus, the quick-release assembly 10 is detachably connected to the printing moving assembly 20. Furthermore, the ink inlet of the ink cartridge 13 is detachably connected to the ink cartridge assembly, and the second electrical connection connector 14 is detachably connected to the first electrical connection connector 22. Therefore, when the UV printhead 12 malfunctions and requires maintenance, the ink inlet and ink cartridge assembly are disassembled, and the second electrical connection connector 14 is disassembled from the first electrical connection connector 22. Then, the quick-release assembly 10 is removed from the printing moving assembly 20, allowing maintenance of the malfunctioning UV printhead 12. Compared to existing technologies, this method involves less disassembly work, facilitates maintenance, and increases maintenance efficiency.
