Description

Technical Field

[0001] This invention belongs to the field of 3D printing technology, and in particular relates to a dual-beam synchronously driven gantry structure 3D printer. Background Technology

[0002] 3D printing, also known as additive manufacturing, is a new type of digital forming technology that differs from traditional subtractive manufacturing and equal-material manufacturing. Based on digital model files, it is a process that uses a layer-by-layer printing and stacking method to build three-dimensional solid objects from various printing materials such as plastics, metals, resins, and ceramics. The core is to decompose complex three-dimensional structures into a series of two-dimensional layers, and then complete the forming by depositing materials point by point, line by line, and layer by layer.

[0003] Current 3D printing equipment suffers from technical defects in the base fixing process, which restricts printing accuracy and work efficiency. Most traditional equipment can only fix the base from one or two directions, making it difficult to simultaneously limit positioning from all directions. The base is prone to horizontal displacement, leading to problems such as misalignment of printed layers and deviations in finished product dimensions. Although some equipment attempts to fix in multiple directions, the multi-power source driven positioning structure is prone to asynchronous power output, making it impossible to accurately align the center and causing uneven force on the base clamping and slight deformation. At the same time, traditional vertical base fixing often uses manual tightening of pressure blocks or separate control of cylinders for clamping, which is cumbersome, inefficient, and prone to uneven clamping force, causing the base to move up and down. In addition, traditional fixing structures have poor adaptability. For bases of different sizes and specifications, it is necessary to change the positioning fixture or adjust the position of positioning components, which is complicated and reduces the overall efficiency of 3D printing and increases the workload of operators.

[0004] To address these issues, we provide a dual-beam synchronously driven gantry structure 3D printer. Summary of the Invention

[0016] The present invention has the following beneficial effects: 1. The present invention uses a single power source to drive the L-shaped support plate of the receiving component to achieve synchronous radial sliding of the four I-shaped plates, which can synchronously abut and position the printing base from four horizontal directions. With the secondary guiding and limiting of the guide tube and the moving rod, the horizontal displacement of the base is effectively prevented. The clamping component uses the base's own squeezing to realize the automatic pressing of the pressure plate, and completes the vertical clamping and fixing, forming a multi-directional fixing effect of horizontal + vertical. The limiting cooperation of the clamping rod and the clamping hole further ensures that the base does not loosen during the printing process. The design of the I-shaped plate in the circumferential array can realize the center alignment of the base. At the same time, the fixing structure can adapt to printing bases of different specifications without the need for additional adjustment of complex structures, which improves the operating efficiency of base fixing and the compatibility range of the equipment.

[0017] 2. This invention employs a dual-head motor synchronously driven bevel gear transmission in the moving component, ensuring that the threaded rods on both sides rotate at the same speed and in the same direction. Combined with the limiting and guiding of the sliding groove, this allows for horizontal adjustment of the receiving component without deviation or jamming, improving the accuracy of alignment between the base and the print head. The printing component relies on the double limiting of the double crossbeam rods and the high-precision transmission of the lead screw to achieve smooth horizontal sliding of the printing equipment. The precise cooperation between the electric push rod and the guide rail ensures smooth vertical movement. At the same time, the moving seat can flexibly adjust its vertical height. Combined with multi-dimensional precise displacement control, this effectively avoids positional deviations during the printing process and significantly improves the accuracy of the 3D printed product.

[0018] 3. This invention utilizes a PLC controller to uniformly regulate various components such as motors, electric push rods, and electromagnets, achieving fully automated operation of the entire process, including component position adjustment, multi-dimensional displacement of the printing equipment, and base fixing and unlocking, without requiring excessive manual intervention. The base is automatically clamped using its own compression, eliminating the need for an additional clamping power source. After printing, the electromagnet-controlled unlocking method responds quickly, and the actions of each linkage structure are smoothly connected. At the same time, the integrated power drive structure of the moving components reduces the complexity of multi-motor control and reduces the cumulative error caused by the asynchrony of multiple motors, making the overall transmission of the equipment more efficient. This not only improves the work efficiency of 3D printing but also reduces the probability of equipment failure. Attached Figure Description

[0022] 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.

[0023] Example 1, please refer to Figure 1-17 The present invention provides the following technical solution: a dual-beam synchronously driven gantry structure 3D printer, including a moving component 1, a printing component 2 fixedly fitted on the top of the moving component 1, and a receiving component 3 fixedly fitted on the top of the moving component 1 below the printing component 2; the moving component 1 provides power for adjusting the position of the receiving component 3 in the horizontal direction; the printing component 2 achieves 3D printing by controlling its movement in the direction perpendicular to the moving component 1 and in the vertical direction; the receiving component 3 is used to simultaneously fix the printing base in four horizontal directions and in the vertical direction, improving the stability of the base and the convenience of use.

[0024] The movable component 1 includes a base 101, a first upright plate 102 symmetrically fixedly connected to the top of the base 101, a threaded rod 103 rotatably connected to one side of the first upright plate 102, a first movable plate 104 symmetrically threadedly connected to the outer wall of the threaded rod 103 and slidingly engaged with the base 101, a first sliding groove 105 symmetrically opened on the top of the base 101 and slidingly engaged with the first movable plate 104, a first bevel gear 106 fixedly connected to one end of the threaded rod 103, a double-headed motor 107 fixedly connected to the top of the base 101, a transmission rod 108 fixedly connected to the output end of each double-headed motor 107, a second bevel gear 109 fixedly connected to the end of the transmission rod 108 and meshing with the corresponding first bevel gear 106, and a control box 110 fixedly connected to the top of the base 101.

[0025] The operation process of this embodiment is as follows: The PLC controller installed inside the control box 110 starts the dual-head motor 107 according to the preset program. The output shafts at both ends of the motor rotate synchronously, driving the transmission rods 108 on the left and right sides to rotate in the same direction and at the same speed. The second bevel gear 109 fixedly installed at the end of the transmission rod 108 rotates accordingly, and transmits power through the first bevel gear 106 meshing with it, thereby driving the threaded rod 103 vertically installed on the first upright plate 102 to rotate. During the rotation of the threaded rod 103, its outer wall is subjected to the helical transmission through the threaded first moving plate 104, and moves horizontally to the left or right along the first sliding groove 105 precisely machined at the top of the base 101, thereby realizing the position adjustment of the receiving component 3 in the horizontal plane. The transmission mechanism adopts a bevel gear meshing method, combined with the synchronous output characteristics of the dual-head motor 107, to effectively ensure that the rotation speed and direction of the threaded rods 103 on both sides are completely consistent. This makes the first moving plate 104 move more smoothly and steadily, avoiding positional deviation or jamming of the receiving component 3 during horizontal adjustment. At the same time, the first slide groove 105 plays a strict limiting and guiding role on the sliding path of the first moving plate 104, further enhancing the stability and rigidity of the overall movement. This integrated power drive structure eliminates the complexity of controlling multiple motors separately, reduces the cumulative error caused by the asynchrony of multiple motors, and significantly improves the accuracy and repeatability of the position control of the receiving component 3. This provides a reliable horizontal adjustment guarantee for the precise alignment of the print head and the substrate in the subsequent 3D printing process.

[0026] Example 2, please refer to Figure 1-17 This second embodiment improves upon the first embodiment as follows: the printing component 2 includes two support plates 201 fixedly connected to the top of the base 101. A horizontal plate 202 is fixedly connected to the top of the support plate 201. A horizontal beam plate 203 is fixedly connected between the two horizontal plates 202. A guide rod 204 is fixedly connected between the bottom of the horizontal beam plate 203 and the base 101. Movable seats 205 are slidably connected to the outer walls of the guide rods 204. A horizontal beam rod 206 is symmetrically fixedly connected between the two movable seats 205. A lead screw 207 located between the two horizontal beam rods 206 is rotatably connected through the two movable seats 205. A first motor 208 is fixedly connected to one side of one movable seat 205. The output end of the first motor 208 is fixedly connected to one end of the lead screw 207. A first rectangular groove 209 is formed through one side of the support plate 201. A first U-shaped plate 210 is fixedly connected between the two movable seats 205 and slides with the two first rectangular slots 209. The first U-shaped plate 210 and the two first rectangular slots 209 are fixedly connected by bolts. A number of screw holes 211 that are connected to the first rectangular slots 209 and are adapted to the bolts are evenly opened on one side of the support plate 201. A slide block 212 is threadedly connected to the outer wall of the lead screw 207. The slide block 212 slides with the two crossbeams 206. A guide rail 213 is fixedly connected to one side of the slide block 212. An L-shaped plate 214 is fixedly connected to the top of the slide block 212. An electric push rod 215 is fixedly connected to the top of the L-shaped plate 214. A slider 216 that slides with the guide rail 213 is fixedly connected to the output end of the electric push rod 215. A 3D printing device 217 is fixedly connected to one side of the slider 216.

[0027] The operation process of this embodiment is as follows: First, according to the actual printing parameter requirements, the vertical height position of the moving seat 205 is pre-adjusted. The first U-shaped plate 210 slides up and down along the first rectangular groove 209 on the support plate 201 until the appropriate working height is reached. Then, it is fastened to the corresponding screw hole 211 with bolts, thereby realizing the reliable fixation of the moving seat 205 in the vertical direction. Next, the PLC controller automatically starts the first motor 208. The first motor 208 outputs torque to drive the lead screw 207 to rotate. The rotation of the lead screw 207 further drives the slide 212 to slide smoothly in the horizontal direction along the two crossbeams 206, thereby completing the precise positioning adjustment of the 3D printing equipment 217 in the direction of the vertical moving component 1. At the same time, the electric push rod 215 installed on the L-shaped plate 214 starts to work, pushing the slider 216 to move up and down in the vertical direction along the guide rail 213, thereby driving the 3D printing equipment 217 to realize the vertical position adjustment. Through the coordinated cooperation of horizontal and vertical movement, high-precision 3D printing processing is finally achieved. In this mechanical structure, the design of the double crossbeam rod 206 provides dual limiting and guiding functions for the horizontal sliding of the slide block 212. Combined with the high-precision transmission mechanism of the lead screw 207, it significantly enhances the stability and positioning accuracy of the 3D printing equipment 217 during horizontal movement. In addition, the vertical height of the moving base 205 can be flexibly adjusted. This design can adapt to the needs of printing bases of different thicknesses and sizes, greatly expanding the application range of the printing equipment. The precise cooperation between the electric push rod 215 and the guide rail 213 ensures the smoothness of the 3D printing equipment 217 when moving in the vertical direction, effectively preventing jamming or deviation, and further ensuring the accuracy of the overall printing operation. The entire transmission system has a simple and compact structure, is convenient and quick to operate, and can significantly improve the work efficiency and product quality of 3D printing.

[0028] Example 3, please refer to Figure 1-17This third embodiment improves upon the first embodiment as follows: the receiving component 3 includes a load-bearing plate 301 fixedly connected to four first movable plates 104. A second upright plate 302 is symmetrically fixedly connected to the top of the load-bearing plate 301. A guide tube 303 is fixedly connected through one side of the second upright plate 302. Moving rods 304 are symmetrically slidably inserted into the inner wall of the guide tube 303. A connecting rod 305 is fixedly connected between adjacent moving rods 304. An extension plate 306 is fixedly connected to the outer wall of the connecting rod 305. A plurality of top rods 307 are symmetrically fixedly connected to the top of the load-bearing plate 301. A circular plate 308 is fixedly connected between the plurality of top rods 307. A circumferentially shaped plate is slidably connected to the top of the circular plate 308. Four I-shaped plates 309 are arranged in an array. Each I-shaped plate 309 is fixedly connected to a first connecting post 310 at its bottom. A second sliding groove 311 is opened through the top of a circular plate 308 to slide with the I-shaped plate 309. Two I-shaped plates 309 arranged opposite each other are fixedly connected to corresponding extension plates 306. A second motor 312 is fixedly connected to the top of a load-bearing plate 301. A rectangular plate 313 is fixedly connected to the output end of the second motor 312. Four second connecting posts 314 are evenly fixedly connected to the bottom of the rectangular plate 313. An L-shaped support plate 315 is rotatably engaged between adjacent first connecting posts 310 and second connecting posts 314. A clamping member 4 is fixedly engaged on the top of the I-shaped plate 309.

[0029] The operation process of this embodiment is as follows: The PLC controller starts the second motor 312, which drives the rectangular plate 313 to rotate. The second connecting column 314 at the bottom of the rectangular plate 313 then performs a circular motion. Through the L-shaped support plate 315 that rotates with the adjacent first connecting column 310, a support-pull transmission is formed, which pulls or pushes the four I-shaped plates 309 to slide synchronously radially along the second sliding groove 311 on the circular plate 308. When the I-shaped plates 309 move, they drive the extension plate 306 to move synchronously. The extension plate 306 pulls the moving rod 304 to slide along the guide tube 303 on the second vertical plate 302 through the connecting rod 305, realizing the synchronous opening and closing of the four I-shaped plates 309 in the horizontal direction, thereby driving the top of the I-shaped plates 309. The clamping component 4 of the part synchronously abuts and positions the printing base from four horizontal directions. In this structure, the single power source of the second motor 312, together with the linkage structure of the L-shaped support plate 315, can ensure the synchronous and accurate movement of the four I-shaped plates 309, effectively avoiding positioning deviation. The cooperation between the guide tube 303 and the moving rod 304 provides secondary guidance and limit for the movement of the I-shaped plates 309, further improving the stability of horizontal positioning. The support of the top rod 307 on the circular plate 308 makes the load-bearing capacity of the supporting structure stronger and can be adapted to printing bases of different specifications. The I-shaped plates 309 distributed in a circumferential array can achieve center alignment and positioning of the printing base, greatly improving the accuracy and convenience of base fixing, and laying the foundation for the stability of subsequent printing operations.

A PLC controller is installed inside the control box 110. The PLC controller is electrically connected to the dual-head motor 107, the first motor 208, the electric push rod 215, the second motor 312, and the electromagnet 422 through wires.

[0031] The operation process of this embodiment is as follows: When the L-shaped side plate 401 moves horizontally towards the printing base and completes contact with the printing base, the printing base squeezes the wedge block 412, pushing the wedge block 412 upward along the second rectangular groove 411. The wedge block 412 simultaneously drives the abutment rod 413 upward and pushes the L-shaped rotating plate 410, causing the L-shaped rotating plate 410 to rotate around the second round rod 409. During the rotation of the L-shaped rotating plate 410, the first round rod 407 is pulled to drive the first vertical plate 406 to slide along the second guide groove 405, thereby pulling the slide plate 403 along the first guide groove 405. The guide groove 402 slides downwards, and the slide plate 403 drives the pressure plate 404 to move downwards synchronously until the pressure plate 404 is tightly pressed against the top of the printing base. At this time, the locking rod 416 is inserted into the locking hole 418 under the elastic force of the second spring 417, completing the position limit of the wedge block 412, realizing the vertical stable fixation of the printing base, and forming a multi-directional fixation effect with the horizontal abutment. After the printing operation is completed, the PLC controller controls the electromagnet 422 to be energized to generate a suction force, attracting the second baffle 421 to drive the pressure rod 420 to slide along the second U-shaped plate 419 and compress the first baffle 420. The three springs 423 and the end of the pressure rod 420 push the locking rod 416 to compress the second spring 417 and disengage it from the locking hole 418, releasing the limit on the wedge block 412. After the wedge block 412 is released from its limit, it resets, simultaneously driving the abutment rod 413 to release the push on the L-shaped rotating plate 410. The L-shaped rotating plate 410 rotates in the opposite direction and resets under the torsion of its own torsion spring, thereby pulling the first round rod 407, the first vertical plate 406, and the sliding plate 403 in a coordinated manner, driving the pressure plate 404 to move upward along the first guide groove 402, releasing the vertical pressing of the workpiece, and completing the overall reset operation. This structure utilizes The base itself compresses to automatically press and fix the pressure plate 404, eliminating the need for additional power to drive the pressing action. The structure is more ingenious. The limiting cooperation between the locking rod 416 and the locking hole 418 ensures the positional stability of the pressure plate 404 after it is pressed, preventing loosening during printing. The electromagnetically controlled unlocking method responds quickly and can achieve automatic reset. Combined with the limiting effect of multiple guide grooves, the up and down movement of the pressure plate 404 is more stable, effectively preventing displacement during pressing and releasing, further improving the fixing stability of the printing base and reducing printing errors caused by base displacement.

[0032] The working principle of this invention is as follows: This dual-beam synchronous drive gantry structure 3D printer is uniformly controlled by the PLC controller inside the control box 110. It achieves integrated 3D printing operations with the moving component 1, printing component 2, and receiving component 3 as the core. Its working principle is as follows: The moving component 1 is driven by a dual-head motor 107, which drives the second bevel gear 109 to mesh with the first bevel gear 106, causing the threaded rod 103 to rotate. This causes the first moving plate 104 to slide horizontally along the first slide groove 105, providing precise horizontal position adjustment power for the receiving component 3. The printing component 2 can first adjust the vertical height of the moving seat 205 according to printing requirements and fix it with bolts and screw holes 211. Then, the first motor 208 drives the lead screw 207, causing the slide 212 to move horizontally along the beam 206. Simultaneously, the electric push rod 215 pushes the slider 216 to move vertically along the guide rail 213, achieving coordinated and precise positioning of the 3D printing equipment 217 in both horizontal and vertical directions. The position adjustment of the print head is completed by the movement of the receiving component 3, which is driven by the second motor 312 to rotate the rectangular plate 313. Through the support and pull transmission of the L-shaped support plate 315, the four I-shaped plates 309 are driven to slide synchronously radially along the second slide groove 311, realizing synchronous contact and positioning of the printing base in four horizontal directions. Under the squeezing action of the horizontal contact of the base, the clamping parts 4 on the I-shaped plates 309 will drive the pressure plate 404 to move automatically downward through the linkage structure such as the wedge block 412 and the L-shaped rotating plate 410, pressing the base from the vertical direction. The cooperation between the clamping rod 416 and the clamping hole 418 realizes the vertical fixation limit. After printing is completed, the PLC controller controls the electromagnet 422 to be energized, and the clamping rod 420 pushes the clamping rod 416 to release the limit. The clamping parts 4 reset and release the workpiece. The entire equipment realizes the multi-directional stable fixation of the printing base and the high-precision displacement of the printing equipment through the linkage of each component, ensuring the stability and accuracy of the 3D printing operation.
