Description

Technical Field

[0001] The present application relates to the technical field of inkjet printing, and particularly relates to an adapter connection structure of a nozzle module and an inkjet printing system. Background Art

[0002] Inkjet printing technology has broad application prospects in many manufacturing fields such as information, energy, medical, and national defense, and is increasingly applied to flexible device fields such as OLED, RFID, thin-film solar cells, wearable flexible devices, PCB, and intelligent skins.

[0003] In order to ensure that the nozzle is in an accurate installation position when performing inkjet printing work, usually, multiple nozzles are first installed in a mounting base that is easier to position on the inkjet printing device to form a mounting module, and then the entire mounting module is installed on the inkjet printing device while completing the docking of each nozzle with the relevant structures on the inkjet printing device. For example, a male adapter and a female adapter are respectively provided on the nozzle and the inkjet printing device, and both belong to a double-row elastic clamping interface type adapter. Since the actual positioning and installation are finally based on the entire mounting module during the installation process, that is, the outermost mounting base, it is necessary to first ensure that each nozzle is installed relatively accurately on the mounting base. At present, in the related art, the position of the nozzle in the mounting base mainly focuses on the following aspects. One is the relative position of the nozzle on the two-dimensional plane in the mounting base, and the other is the degree of parallelism between the length direction of the nozzle and the pre-determined standard arrangement direction in the mounting base. Therefore, a mounting groove with a size larger than the nozzle mounting surface is provided in the mounting base, and there are gaps between each side of the nozzle and the mounting groove. At the same time, an adjustment component capable of adjusting the position of the nozzle in all directions is provided in the mounting plate to meet the position adjustment requirements in the above two aspects. Among them, since the degree of relative parallelism is more difficult to adjust and the adjustment amount is relatively smaller, the adjustment of the relative parallelism is usually performed after the relative position of the nozzle on the two-dimensional plane is adjusted.

[0004] However, during the adjustment of the relative parallelism of each nozzle, there is a high possibility that the entire nozzle will undergo a slight translation in the width direction, resulting in a certain error in the position of the nozzle in the width direction when the parallelism adjustment is finally completed. Especially when the errors of two adjacent nozzles in the width direction are on different sides, the distance error between the two nozzles will be further increased. Although the position error amount in the width direction is very small, it can still ensure that the inner joint of the male adapter contacts the elastic contact piece in the female adapter during the installation and docking process of the nozzle module, as shown in Figure 1, but when the position error exceeds the error compensation ability of the elastic tabs inside the female adapter head, that is, when one side of the elastic tab has rotated to the maximum allowable deflection angle Θ but the male adapter head still cannot be inserted further, if the docking is continued automatically at this time, it will cause damage to the adapter structure, as shown in Figure 1 . Based on this problem, in related technologies, the female adapter head is often freely connected to the inkjet printing device, and after the nozzle is installed, the female adapter head and the male adapter head are plugged together manually to achieve the smooth installation of the nozzle. As a result, the installation process of the nozzle module is inefficient, and at the same time, it also affects the development of the overall automation technology of the inkjet printing system. Summary of the Invention

[0038] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present application.

[0039] An adapter connection structure of a nozzle module provided by the present application, the invention point thereof lies in that the female adapter is movably installed in the docking direction and the position error direction of the male adapter, and a first elastic member is provided in the docking direction to resist the female adapter, so that during the insertion process of the female adapter and the male adapter, the male adapter with a position error contacts the elastic contact piece on one side inside the female adapter through its internal docking joint, and can first drive the female adapter to deflect as a whole. After the docking joint moves to form contacts with the elastic contact pieces on both sides inside the female adapter, the elastic contact pieces on both sides can be driven to expand and elastically clamp them during the subsequent movement process, ensuring that the male adapter can successfully complete the insertion fit with the female adapter under the condition of a large position error, effectively increasing the error compensation amount of the female adapter, and the entire insertion fit process does not require personnel participation, effectively solving the problems of low efficiency caused by manual docking of the adapter during the installation of the nozzle module in the related art and affecting the overall automation of the nozzle printing technology.

[0040] To make the purpose, technical solution and advantages of the present application clearer, the embodiments of the present application will be further described in detail below in conjunction with the drawings.

[0041] In the first aspect, refer to Figure 2, an embodiment of the present application provides an adapter connection structure for a nozzle module, which includes a mounting plate 1, a female adapter 2, and a resisting portion 3.

[0042] Among them, the mounting plate 1 is fixedly installed on the inkjet printing device, and is provided with a mounting station for installing the female adapter 2. The mounting station is provided with two spaced-apart first limiting walls 110, and the two first limiting walls 110 are arranged along the first direction.

[0043] The female adapter 2 is installed and arranged between the two first limiting walls 110, its width direction is the same as the first direction, and there are gaps between it and the two first limiting walls 110, so that it can move in its width direction. At the same time, the female adapter 2 is also movably arranged as a whole in the docking direction. Specifically, the docking direction is specifically the direction when the male adapter 5 and the female adapter 2 of the nozzle module are inserted and matched during the actual installation process. In different embodiments, it can be correspondingly changed according to different settings in the installation process of the nozzle module. The present application does not limit this here. For the convenience of understanding the technical solution provided by the present application, the present application further describes an embodiment in which the male adapter 5 and the female adapter 2 of the nozzle module are docked in the vertical direction. In such embodiments, the docking direction of the male adapter 5 and the female adapter 2 is in the vertical direction, corresponding to the Z direction in the figure; at this time, the mounting plate 1 is horizontally arranged, and the female adapter 2 is vertically installed on the mounting plate 1. The width direction of the female adapter and the first direction correspond to the X direction in the figure, and the length direction of the female adapter corresponds to the Y direction in the figure.

[0044] The resisting portion 3 is fixedly installed on the mounting plate 1 and is upstream of the female adapter 2 in the docking direction. A first elastic member 4 is arranged between the mounting plate 1 and the resisting portion 3, and the upper and lower ends of the first elastic member 4 are respectively in contact with the resisting portion 3 and the female adapter 2, so as to provide an upward elastic resistance to the female adapter 2, that is, to elastically resist and limit the female adapter 2 in the docking direction.

[0045] It should be noted that the elastic modulus of the first elastic member 4 needs to be less than the elastic modulus of the elastic contact piece 21 in the female adapter 2. Furthermore, referring to Figure 5 , when the female adapter 2 and the male adapter 5 are inserted and matched based on a certain error, the docking joint 50 in the male adapter 5 can first drive the female adapter 2 to deflect as a whole after contacting one side of the elastic contact piece 21 in the female adapter 2 due to a position deviation, until both sides of the elastic contact piece 21 in the female adapter are in contact with the docking joint 50 in the male adapter 5. With the further insertion of the male adapter 5, at this time, the two elastic contact pieces 21 will expand and elastically clamp the male adapter 5, and finally complete the docking with the female adapter 2.

[0046] Optionally, referring to Figure 3 , in some embodiments, the installation stations provided on the mounting plate 1 include mounting notches 11 formed on the mounting plate 1. The mounting notches 11 are rectangular notches matching the female adapter 2, including two groups of inner walls perpendicular to each other, namely two first limiting walls 110 in the first direction and two second limiting walls 111 in the second direction. Among them, the first direction is specifically the direction in which the nozzle has a position error during the docking process of the nozzle module, that is, the width direction of the male adapter 5 on the nozzle. At the same time, during the subsequent installation of the female adapter 2, the width direction of the female adapter 2 will also be consistent with the first direction. The second direction corresponds to the length direction of the female adapter 2 and the male adapter 5. At the same time, the distance between the two first limiting walls 110 is greater than the width of the subsequent female adapter 2, and when the female adapter 2 is installed therein, an activity gap is formed between the two groups of first limiting walls 110 and the female adapter 2. In addition, the distance between the two second limiting walls 111 is at least sufficient to allow the female adapter 2 to be installed therein in the length direction, that is, not less than the length of the female adapter 2.

[0047] Optionally, referring to Figure 3 and Figure 4 , in some embodiments, to achieve the movable installation of the female adapter 2 on the mounting plate 1 in the width direction and the docking direction, hanging ears 20 are fixedly connected to both ends of the top of the female adapter 2 in the length direction. During the installation process of the female adapter 2, it will first be placed on the mounting plate 1 through the bottom surfaces of the two hanging ears 20, so that the female adapter 2 is placed on the mounting plate 1, and the female adapter 2 can move in both the width direction and the vertical direction. Since the female adapter 2 is placed on the mounting plate 1 through the hanging ears 20 at both ends, when it is inserted and matched with the male adapter 5 with a certain error and causes an overall deflection, it can be integrally flipped based on the contact surface between the hanging ears 20 and the mounting plate 1.

[0048] Further, in some embodiments, the contact surface between the hanging ears 20 and the mounting plate 1 is provided with a curved surface such as a round roller surface or a spherical surface (not shown in the figure), and the center of the round roller surface or the spherical surface is on the symmetry axis of the elastic tabs 21 on both sides of the female adapter 2. In some other embodiments, the contact surface between the hanging ears 20 and the mounting plate 1 is provided as a plane, referring to Figure 4 , and the symmetry axis corresponding to this plane in the first direction is coaxial with the symmetry axis of the elastic tabs 21 on both sides inside the female adapter 2.

[0049] With such a setting, it is ensured that when the female adapter head 2 is integrally flipped based on the contact surface between the lugs 20 and the mounting plate 1, it has symmetry for error compensation. That is, regardless of which side of the symmetry axis of the female adapter head 2 the position deviation between the male adapter head 5 and the female adapter head 2 is located, when the position deviation amount is the same, the final overall deflection angle amount required for the female adapter head 2 is the same, only the deflection directions are different. Furthermore, it is ensured that the female adapter head 2 can perform consistent compensation for the possible position deviation of the male adapter head 5 within the limited movement gaps on both sides.

[0050] In this embodiment, the contact surface between the lugs 20 and the mounting plate 1 is preferably the planar contact surface in the above solution. And the distance of the bottom surface of the lugs 20 in the first direction is greater than the distance between the two elastic tabs 21 on both sides inside the adapter nozzle in the first direction. Furthermore, when the female adapter head 2 is integrally deflected relative to the mounting plate 1 by using the lugs 20, it can be deflected with one side edge of its bottom surface as the rotation axis, and the two elastic tabs 21 inside it will be on the same side of the rotation axis.

[0051] With such a setting, referring to Figure 6 the docking process between the male adapter head 5 and the female adapter head 2 when the rotation axis of the lugs 20 is in different solutions, it can be seen that in this embodiment, when the female adapter head 2 is integrally deflected until the docking joints 50 on both sides of the male adapter head 5 are in contact with the two elastic tabs 21 on both sides of the female adapter head 2 at the same time, the distance that the male adapter head 5 needs to move in the docking direction (see the schematic diagram of state 5c in Figure 5 ) is relatively larger than the solution where the rotation axis is on the symmetry axis line of the two elastic tabs 21 on both sides (see the schematic diagram of state 5b in Figure 5 ). Furthermore, it further guarantees the movement control of the male adapter head 5 during docking, avoiding the situation that it is difficult for the driving component of the male adapter head 5 to accurately control the position of the male adapter head 5 within a small scale when the movement distance is too small, especially in the existing situation where the movement control of the nozzle module often relies on driving structures such as actuating cylinders during the automated installation process of the nozzle module.

[0052] Furthermore, referring to Figure 4, a limiting shaft hole vertically axially provided is arranged inside the ear hook 20, and a docking hole 12 coaxial with the limiting shaft hole is arranged on the mounting plate 1; in addition, the mounting station further includes a connecting bolt 13 whose one end passes through the limiting shaft hole from above the ear hook 20 and extends to be in threaded cooperation with the docking hole 12, and the connecting bolt 13 has a bolt head 130 above the ear hook 20, and a resisting portion 3 for resisting the first elastic member 4 is formed by the bolt head 130. It should be noted that the diameter of the limiting shaft hole is larger than the rod diameter of the connecting bolt 13, so that an activity gap is left between the connecting bolt 13 and the circumferential side wall of the limiting shaft hole when the connecting bolt 13 passes through the limiting shaft hole, ensuring that the adapter female head 2 can deflect as a whole.

[0053] In addition, due to the arrangement of the connecting bolt 13, when the adapter female head 2 is installed on the mounting plate 1, its installation position will be limited within a certain range, that is, the adapter female head 2 can always be installed within the set range. Furthermore, in this embodiment, by making the opening position of the docking hole 12 correspond to the midpoint of the mounting slot 11 in the first direction, it can be ensured that the adapter female head 2 is in a relatively centered position within the mounting slot 11, so that the adapter female head 2 has a suitable activity space in the first direction while having a high installation accuracy, waiting to be docked with the adapter male head 5.

[0054] Optionally, in some embodiments, a plurality of mounting stations are arranged on the mounting plate 1, and a plurality of adapter female heads 2 are also provided corresponding to the plurality of mounting stations. Specifically, by arranging a plurality of mounting stations and a plurality of adapter female heads 2 on the mounting plate 1, when there are multiple nozzles in the nozzle module to be installed, the adapter male heads 5 corresponding to each nozzle can be docked with the adapter female heads 2 first installed on the mounting plate 1. It should be noted that the number of mounting stations on the mounting plate 1 is not limited to one-to-one correspondence with the number of adapter female heads 2 required by the installed nozzle module. The number of mounting stations on the mounting plate 1 can be more, and then the adapter female heads 2 can be installed on the corresponding multiple mounting stations according to the number of adapter female heads 2 required by different nozzle modules.

[0055] Furthermore, in some embodiments, a plurality of resisting portions 3 corresponding to the adapter female head 2 are provided, and the mounting positions of the resisting portions 3 in the docking direction are adjustable. Specifically, the connecting bolt 13 and the docking hole 12 can be adjusted in height in the vertical direction to achieve the adjustable position of the bolt head 130 in the vertical direction, that is, the mounting position of the resisting portion 3 in the docking direction is adjustable.

[0056] With such a setting, each resisting portion 3 can be independently adjusted in height, so as to ensure that each resisting portion 3 can be at the same height, and the adapter female heads 2 and the first elastic members 4 have more accurate mounting positions and mounting states.

[0057] Optionally, in some embodiments, the first elastic member 4 includes a flexible pad 40 that can be deformed and compressed in any direction. The two sides of the flexible pad 40 are respectively abutted against the resisting portion 3 and the female adapter head 2. Specifically, in this embodiment, the bottom surface of the flexible pad 40 covers the top surface of the female adapter head 2, and its top surface abuts against the bottom surface of the bolt head 130. A through hole 401 for the connecting bolt 13 to pass through is provided in the flexible pad 40. At the same time, based on its deformation characteristics, a zero clearance or interference fit can be formed between the through hole 401 and the connecting bolt 13. While wrapping the connecting bolt 13 therein, the contact surface with the connecting bolt 13 is also isolated from the outside, having good sealing performance. Among them, different elastic materials can be selected for the first elastic member 4 in different embodiments, such as polyurethane, nitrile rubber, silicone rubber, etc. In this embodiment, the first elastic member 4 is preferably fluororubber. Based on its good anti-corrosion effect, it can effectively reduce the occurrence of corrosion problems when ink splashes on it during the subsequent work of the nozzle module.

[0058] With such a setting, it is realized that the flexible pad 40 can be compressed and deformed in all directions in space. When the female adapter head 2 is docked with the male adapter head 5, the first elastic member 4 can be deformed and matched more smoothly. At the same time, the flexible pad 40 follows the overall deflection of the female adapter head 2, and the movement process is basically compression deformation, and there is basically no relative sliding friction. Therefore, its wear is lower, effectively reducing the occurrence of magazine particles due to material wear, and avoiding the influence on the work of the nozzle module when the magazine particles diffuse outward. Especially when the nozzle module is working on high-precision products, such as OLED, RFID and other products, fine impurities will affect the final quality of the products. The flexible pad 40 can bring better effects based on this requirement.

[0059] Furthermore, in some other embodiments, the first elastic member 4 includes a spring. The telescopic axis of the spring is in the docking direction, and both ends are respectively abutted against the resisting portion 3 and the female adapter head 2. And in order to reduce the bending degree of the spring when the female adapter head 2 is deflected as a whole, thereby improving the service life of the spring, the spring is sleeved outside the rod body of the connecting bolt 13, and the connecting bolt 13 is relied on to provide compression guidance for the spring. At the same time, the bottom end of the spring is arranged to be relatively slidable with respect to the female adapter head 2 to ensure that the spring can be compressed integrally in the vertical direction when the female adapter head 2 is flipped.

[0060] Optionally, in some embodiments, there is also a movable gap between the two second limiting walls 111 on the two sides in the second direction in the installation notch 11 and the female adapter head 2. With such a setting, there are gaps between the female adapter head 2 and the mounting plate 1 on all sides, which facilitates the installation of the female adapter head 2, and at the same time avoids friction between the two sides of the female adapter head 2 and the mounting plate 1 when the female adapter head 2 is flipped, thereby reducing the resistance when the female adapter head 2 moves, and being more conducive to accurately controlling the docking of the female adapter head 2 and the male adapter head 5.

[0061] Optionally, in some embodiments, the adapter connection structure of the nozzle module further includes at least two second elastic members 6. The two second elastic members 6 are respectively and fixedly disposed on the mounting plates 1 on both sides of the adapter female head 2 in the first direction. Specifically, they are elastic flappers 60 with one end fixedly connected to the mounting plate 1 and the other end extending along the docking direction. A contact end 600 is provided on the side of the elastic flapper 60 close to the adapter female head 2 in the first direction, and the contact end 600 extends in the first direction to contact the side wall of the adapter female head 2. After the second elastic member 6 is pushed, it can elastically deflect in the first direction. Then, through the second elastic member 6, after the adapter female head 2 deflects to one side in the first direction, the second elastic member 6 will synchronously deflect and deform, thereby providing an elastic force to the adapter female head 2, and after the adapter male head 5 is separated from the adapter female head 2, it can drive the adapter female head 2 to reset to the initial position.

[0062] Specifically, in some embodiments, although the adapter female head 2 can be driven by the elasticity of the first elastic member 4 to reset to the initial position after being separated from the adapter male head 5, since the first elastic member 4 acts on the top of the adapter female head 2, which is relatively closer to the rotation axis where the adapter female head 2 deflects, therefore, its acting moment is relatively smaller. As a result, if the first elastic member 4 is required to drive the reset, the first elastic member 4 needs to provide a relatively large elastic force, that is, the first elastic member 4 needs to have a relatively large elastic modulus. However, since the elastic modulus of the first elastic member 4 in this case needs to be less than the elastic modulus of the elastic contact piece 21 in the adapter female head 2, the setting of the first elastic member 4 is difficult to achieve in practice, especially when the overall mass of the adapter female head 2 is relatively large, the two are contradictory and cannot be achieved.

[0063] Therefore, in the present application, the second elastic members 6 are further provided on both sides of the adapter female head 2 to drive the side wall of the adapter female head 2 far from the rotation axis, so that the second elastic member 6 has a larger acting moment when driving the adapter female head 2 to reset, thereby reducing the elastic force that the second elastic member 6 needs to provide when resetting the adapter female head 2, and finally reducing the thrust that the adapter male head 5 needs to exert during plugging, so as to ensure that the adapter female head 2 and the adapter male head 5 can be stably docked.

[0064] Further, referring to Figure 2, in some embodiments, the simultaneous contact end 600 is specifically a contact protrusion integrally formed on the elastic flap 60, and the contact protrusion is provided with a curved surface, so that the elastic flap 60 can be tangent to the side wall of the adapter female head 2 as much as possible during the process of driving the adapter female head 2, and thus the provided elastic force can more effectively drive the adapter female head 2 to reset, further reducing the elastic modulus required for the second elastic member 6. In addition, in other embodiments, the contact end 600 can also be a contact roller rotatably arranged on the elastic flap 60, realizing the conversion of the sliding friction between the contact end 600 and the elastic flap 60 into rolling friction, and further reducing the elastic force required for the second elastic member 6 to drive and reset the adapter female head 2.

[0065] In addition, for the embodiments in which there is a clearance between the two second limiting walls 111 in the second direction and the adapter female head 2, in order to ensure that the adapter female head 2 can also be accurately installed in the second direction, elastic flaps 60 are also provided on both sides of the adapter female head in the second direction, that is, the front and back in the length direction of the adapter female head 2, so as to assist the adapter female head 2 to be arranged and installed at the required position in the installation slot 11 in the length direction.

[0066] In a second aspect, the present application provides an inkjet printing system, adopting the following technical solution:

[0067] An inkjet printing system includes at least one adapter connection structure of the nozzle module as described above. Among them, the structural features and functional effects of the adapter connection structure of the nozzle module have been analyzed in detail above and will not be elaborated here.
