Description

Technical Field

[0001] This application belongs to the field of resin tank mounting structure, and specifically relates to a resin tank mounting structure for a 3D printer. Background Technology

[0002] With the rapid development of 3D printing technology, photopolymer 3D printing has been widely used in industrial manufacturing, medical modeling, jewelry design and other fields due to its advantages of high precision and high surface quality. Among them, the resin tank, as the core component of the photopolymer printer, is responsible for carrying the photosensitive resin and achieving layer-by-layer curing with the help of ultraviolet light. Its installation stability directly affects the printing accuracy and efficiency. In recent years, with the increasing demand for multi-material printing and large-size model making, higher requirements have been placed on the rapid replacement, adaptability and clamping stability of the resin tank, which has promoted the technological upgrading of the resin tank installation structure.

[0003] In photopolymer 3D printers, the resin tank needs to maintain a strict relative position with the printing platform and withstand the shaking of the resin and the repeated lifting and lowering impacts of the platform during the printing process. Traditional resin tank installation structures mostly use fixing clips, screw locks, or magnetic attraction. Their core design focuses on the "fixing" function and does not fully consider adaptability in multiple scenarios. As users' demands for printing efficiency (such as quick material change) and equipment versatility (such as compatibility with resin tanks of different specifications) increase, the existing structure is gradually revealing its functional limitations and urgently needs to be optimized in terms of automated clamping, adaptability, and stability.

[0004] The shortcomings of existing technology.

[0005] 1) Insufficient clamping stability affects printing accuracy: Traditional structures rely on manual tightening of screws or locking clips, which can easily cause slight tilting of the resin tank due to uneven force; and lack self-locking function. During the printing process, the resin may shake or the equipment may vibrate, causing loosening and displacement, resulting in layer thickness deviation and model edge misalignment, which is more obvious in large-size resin tank (heavy load) scenarios.

[0006] 2) Poor adaptability and cumbersome operation: The fixing clips or screw holes are mostly specially designed and can only be used with resin tanks of specific sizes. When changing to different sizes of tanks, the entire mounting base needs to be disassembled, which is time-consuming and laborious. Moreover, the disassembly and assembly process relies on tools, which has a high operating threshold and is not convenient for quick switching in multi-material printing scenarios, thus reducing the efficiency of equipment use. Utility Model Content

[0007] The purpose of this invention is to provide an installation structure for the resin tank of a 3D printer, so as to solve the problems of insufficient clamping stability, poor adaptability and cumbersome operation of existing equipment.

[0008] The first aspect of this application provides an installation structure for a resin tank of a 3D printer, comprising: a set of mounting bases, a work plate fixedly mounted on the top of each set of mounting bases, a first sliding plate fixedly mounted on the top of the work plate, a set of sliding slots opened on the top of the first sliding plate, a set of second sliding plates slidably disposed inside each of the sliding slots, a clamping seat fixedly mounted on the top of the set of second sliding plates by screws, and a fixing component fixedly mounted on both outer surfaces of each clamping seat by screws.

[0009] Preferably, each of the fixed components has a threaded portion with a fastening nut, and each fastening nut is used to fix the fixed component and the outer edge of the working plate.

[0010] Preferably, a set of first sliding components is slidably disposed on the top of the work plate, and each of the first sliding components is screwed to a mounting post.

[0011] Preferably, a connecting plate is screwed onto the outer surface of each mounting post, and a spring is fixedly connected to the outer surface of each connecting plate.

[0012] Preferably, a clamping plate is fixedly connected to one end of each spring, and a motor mounting part is fixedly connected to the bottom of the working plate.

[0013] Preferably, the output end of the motor is fixedly connected to a rotating arm, and the top of the rotating arm is fixedly connected to a set of rotating shafts, and the rotating part of each rotating shaft is rotatably connected to a transmission arm.

[0014] Preferably, the rotating part of each of the transmission arms is rotatably connected to a rotating shaft seat, and the bottom of the rotating shaft seat is fixedly connected to the top of the first sliding assembly by screws.

[0015] Preferably, each of the clamping seats has a placement component movably disposed inside, and a resin tank body is fixedly installed on the top of a set of placement components by screws.

[0016] Preferably, each of the clamping plates corresponds to and cooperates with the interior of the clamping seat to fix the corresponding placement component.

[0017] Preferably, the motor has a braking function to solve the problem of the lack of a self-locking structure in the device, and a set of connecting brackets is fixedly connected to the outer surface of each mounting base, the connecting brackets being used for fixed connection with the inside of the printer.

[0018] In some possible embodiments, the resin tank mounting structure for a 3D printer provided in this application has all the beneficial effects of the fastener, which will not be described in detail here.

[0019] Compared with the prior art, the technical solution provided in this application includes at least the following technical effects: 1. This utility model utilizes a transmission mechanism composed of a motor-driven rotating arm and a transmission arm to move the first sliding component and the clamping plate. Combined with the elastic buffering effect of the spring, it can provide a stable and uniform clamping force for the placed component, avoiding damage to the resin tank that may be caused by rigid clamping. At the same time, the motor's braking function effectively solves the problem of the lack of a self-locking structure in the equipment, ensuring a stable clamping state during the printing process and reducing displacement of the resin tank caused by vibration or external force. This is the core of ensuring printing accuracy. Compared with the traditional structure that relies on manual fixing or simple buckles, it has a fundamental improvement in stability.

[0020] 2. This utility model, through the cooperation of the sliding groove of the first sliding plate and the second sliding plate, combined with the locking function of the fixing component and the fastening nut, realizes the flexible adjustment of the position of the clamping seat, which can be adapted to different sizes of placement components and resin tank bodies, improving the versatility of the installation structure. Moreover, the movable cooperation design of the placement component and the clamping seat, combined with the elastic clamping of the clamping plate, makes the disassembly and assembly of the resin tank without complicated tools, improving the convenience of operation. It solves the problems of poor adaptability and cumbersome replacement of traditional fixing methods, and has significantly optimized the degree of automation and ease of use.

[0024] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0026] In some embodiments, please refer to the appendix. Figure 1 To be continued Figure 5 As shown: An installation structure for a resin tank of a 3D printer includes: a set of mounting bases 1, a work plate 2 fixedly mounted on the top of each set of mounting bases 1, a first sliding plate 21 fixedly mounted on the top of the work plate 2, a set of sliding slots 22 opened on the top of the first sliding plate 21, a set of second sliding plates 3 slidably arranged inside each sliding slot 22, a clamping seat 31 fixedly mounted on the top of the set of second sliding plates 3 with screws, and a fixing component 32 fixedly mounted on both outer surfaces of each clamping seat 31 with screws.

[0027] In this embodiment, the mounting base 1 serves as a basic support, providing a stable mounting foundation for the entire mounting structure. The working plate 2 is fixed on the top of the mounting base 1 and serves as a bearing platform for the installation of various components. The sliding groove 22 on the first sliding plate 21 provides a sliding track for the second sliding plate 3, enabling the second sliding plate 3 to drive the clamping base 31 to adjust its position, thereby adapting to different sizes of placement components 6 and resin tank bodies 61. The fixing component 32 is used to fix the second sliding plate 3 in place with the fastening nut 33 after it has been adjusted to a suitable position, ensuring the stability of the clamping base 31.

[0028] In some embodiments, please refer to the appendix. Figure 1 To be continued Figure 5 As shown: Each fixing component 32 has a threaded connection to a fastening nut 33, and each fastening nut 33 is used to fix the fixing component 32 and the outer edge of the working plate 2.

[0029] In this embodiment, the fastening nut 33 engages with the threaded portion of the fixing component 32. By tightening the fastening nut 33, the fixing component 32 can be pressed tightly against the outer edge of the working plate 2, thereby locking the second sliding plate 3. This prevents the second sliding plate 3 from shifting position due to vibration or other reasons during equipment operation, ensuring the stability of the clamping seat 31 and providing a guarantee for the stable placement of the resin tank body 61.

[0030] In some embodiments, please refer to the appendix. Figure 1 To be continued Figure 5 As shown: A set of first sliding components 4 are slidably arranged on the top of the working plate 2, and each first sliding component 4 is screwed to the top of the mounting post 41.

[0031] In this embodiment, the first sliding component 4 can slide on the top of the working plate 2. Its sliding provides a basis for the movement of the mounting post 41. The mounting post 41 is fixed to the first sliding component 4 by screws and moves with the sliding of the first sliding component 4. It is an important carrier for connecting subsequent components, providing installation positions for components such as the connecting plate 42, spring 43 and clamping plate 44, and transmitting the sliding of the first sliding component 4 to these components.

[0032] In some embodiments, please refer to the appendix. Figure 1 To be continued Figure 5 As shown: Each mounting post 41 has a connecting plate 42 fixedly mounted on its outer surface with screws, and each connecting plate 42 has a spring 43 fixedly connected to its outer surface.

[0033] In this embodiment, the connecting plate 42 serves as a connector, connecting the mounting post 41 and the spring 43 together, so that the movement of the mounting post 41 can be transmitted to the spring 43. The spring 43 is elastic and can play a buffering role during the clamping process, avoiding excessive rigid impact force from the clamping plate 44 on the placement component 6, preventing damage to the placement component 6 and the resin tank body 61 due to excessive force, and also ensuring the uniformity of the clamping force.

[0034] In some embodiments, please refer to the appendix. Figure 1 To be continued Figure 5 As shown: One end of each spring 43 is fixedly connected to a clamping plate 44, and the bottom of the working plate 2 is fixedly connected to the mounting part of the motor 5.

[0035] In this embodiment, the clamping plate 44 is a component that directly contacts the placement component 6 and performs the clamping action. Under the action of the spring 43, it can fit tightly against the placement component 6 and fix it in the clamping seat 31. The motor 5 is fixed to the bottom of the working plate 2 through the mounting part, providing power for the movement of the entire mechanism and serving as the power source for clamping and transmission.

[0036] In some embodiments, please refer to the appendix. Figure 1 To be continued Figure 5 As shown: The output end of the motor 5 is fixedly connected to a rotating arm 51, and the top of the rotating arm 51 is fixedly connected to a set of rotating shafts 52. The rotating part of each rotating shaft 52 is rotatably connected to a transmission arm 53.

[0037] In this embodiment, when the motor 5 is working, its output end drives the rotating arm 51 to rotate. The rotation of the rotating arm 51 drives the rotating shaft 52 fixed on its top to rotate together. The rotating shaft 52 is rotatably connected to the rotating part of the transmission arm 53, so that the rotation of the rotating shaft 52 can be converted into the swing of the transmission arm 53, thereby transmitting the power of the motor 5 to the subsequent components, realizing the transmission of power and the conversion of motion form.

[0038] In some embodiments, please refer to the appendix. Figure 1 To be continued Figure 5 As shown: The rotating part of each transmission arm 53 is rotatably connected to a rotating shaft seat 54, and the bottom of the rotating shaft seat 54 is fixedly connected to the top of the first sliding assembly 4 by screws.

[0039] In this embodiment, the transmission arm 53 is rotatably connected to the rotating shaft seat 54 via a rotating part. When the transmission arm 53 swings, it will drive the rotating shaft seat 54 to move. Since the rotating shaft seat 54 is fixed to the top of the first sliding assembly 4 by screws, the movement of the rotating shaft seat 54 will drive the first sliding assembly 4 to slide on the top of the working plate 2, thereby realizing the conversion of the swing of the transmission arm 53 into the sliding of the first sliding assembly 4, providing power for the movement of the clamping plate 44.

[0040] In some embodiments, please refer to the appendix. Figure 1 To be continued Figure 5 As shown: Each clamping seat 31 has a placement component 6 movably installed inside, and a resin tank body 61 is fixedly installed on the top of a set of placement components 6 by screws.

[0041] In this embodiment, the clamping seat 31 provides a placement space and positioning for the placement component 6. The placement component 6 can move within the clamping seat 31, making it easy to install and remove. The resin tank body 61 is fixed to the top of the placement component 6 with screws. The placement component 6 plays a role in bearing and fixing the resin tank body 61, ensuring the stability of the resin tank body 61 during operation, and also facilitating the replacement and maintenance of the resin tank body 61.

[0042] In some embodiments, please refer to the appendix. Figure 1 To be continued Figure 5 As shown: Each clamping plate 44 corresponds to and cooperates with the interior of the clamping base 31 to fix the corresponding placement component 6.

[0043] In this embodiment, the clamping plate 44 and the interior of the clamping seat 31 cooperate with each other to form a clamping structure for the placement component 6. When the clamping plate 44 moves into the clamping seat 31 under the action of power, it works together with the inner wall of the clamping seat 31 to firmly fix the placement component 6 in the clamping seat 31, preventing the placement component 6 from shaking or shifting during operation, thereby ensuring the stability of the resin tank body 61. In some embodiments, please refer to the attached diagram. Figure 1 To be continued Figure 5 As shown: Motor 5 has a braking function to solve the problem of the lack of a self-locking structure in the device. Each mounting base 1 has a set of connecting brackets 11 fixedly connected to its outer surface. The connecting brackets 11 are used to fix the connection to the inside of the printer.

[0044] In some embodiments, please refer to the appendix. ​ To be continued ​ As shown: Motor 5 has a braking function to solve the problem of the lack of a self-locking structure in the device. Each mounting base 1 has a set of connecting brackets 11 fixedly connected to its outer surface. The connecting brackets 11 are used to fix the connection to the inside of the printer.

[0045] In this embodiment, the braking function of the motor 5 can lock its output shaft when the motor 5 stops working, preventing the components from moving under gravity or external force due to the lack of a self-locking structure of the equipment, thus ensuring the stability of the clamping state. The connecting frame 11 fixes the mounting base 1 to the inside of the printer, thereby fixing the entire resin tank mounting structure inside the printer and ensuring the overall stability of the structure during the operation of the printer.

[0046] Working principle: First, the entire mounting structure is fixed inside the printer by the connecting bracket 11. Based on the dimensions of the resin tank body 61, the second sliding plate 3 is slid to adjust the position of the clamping seat 31. Then, the second sliding plate 3 is fixed by the fixing component 32 and the fastening nut 33. The placement component 6, along with the resin tank body 61, is placed into the clamping seat 31. The motor 5 is started, and the output end of the motor 5 drives the rotating arm 51 to rotate. The rotating arm 51 drives the transmission arm 53 to swing through the rotating shaft 52. The transmission arm 53 drives the transmission arm 53 to swing through the rotating shaft seat 54. The first sliding component 4 slides on the working plate 2. The first sliding component 4 drives the mounting column 41, the connecting plate 42 and the spring 43 to move, so that the clamping plate 44 moves into the clamping seat 31. Under the elastic action of the spring 43, the clamping plate 44 cooperates with the clamping seat 31 to fix the placement component 6. The braking function of the motor 5 ensures the stability of the clamping state during the operation. When it is necessary to replace or remove the resin tank body 61, the motor 5 reverses, drives each component to reset, the clamping plate 44 is released, and the placement component 6 and the resin tank body 61 can be taken out.
