Description

Technical Field

[0001] The present invention relates to the technical field of 3D printers, in particular to a negative pressure adsorption type rapid demoulding printing platform. Background Art

[0002] Driven by the dual advancements of 3D printing technology towards industrial applications and consumer adoption, printing efficiency and model quality have become core optimization priorities. Negative pressure adsorption printing platforms, with their active and uniform adsorption force, address the warping and displacement issues of traditional heating platforms when printing large parts and complex structures. These platforms have become a key technology for high-precision printing. However, with the growing demand for large-scale printing, such as in small-batch production and educational training, the limitations of traditional platforms, such as the time-consuming manual demolding process and the risk of damage to the model, have become increasingly apparent. Therefore, we propose a negative pressure adsorption rapid demolding printing platform.

[0003] The prior art also has the following defects during use: In the prior art, negative pressure adsorption rapid demoulding printing platforms require a number of micropores to achieve negative pressure adsorption. However, these micropores can easily allow incompletely solidified printed substrate to penetrate, thereby clogging the pores and affecting the negative pressure adsorption effect. The negative pressure adsorption rapid demoulding printing platform in the existing technology adopts the ejection method for rapid demoulding. However, since the ejection method requires space for the movement of the lifting mechanism, it will affect the negative pressure adsorption effect of the printing platform and increase the probability of leakage of the printed substrate. The ejection demoulding method will also cause uneven force on the printed structure, resulting in damage during the demoulding process.

[0004] In view of this, we propose a negative pressure adsorption rapid demoulding printing platform to solve the existing problems. Summary of the Invention

[0018] The technical solution of the present invention is further described below with reference to the accompanying drawings and specific embodiments.

[0019] like Figure 1 - Figure 9 As shown, the present invention proposes a negative pressure adsorption type rapid demoulding printing platform, including a mounting frame 1, a printing plate 4, a crossbar assembly 6 and a sliding seat 7. A bottom plate 105 is fixedly installed at the bottom of the mounting frame 1, and two groups of threaded seats 102 are fixedly installed on both sides of the bottom of the bottom plate 105, and a threaded hole and a round hole are opened inside the threaded seat 102. The mounting frame 1 can provide a mounting position for the surrounding components, and the bottom plate 105 can provide a mounting position for the surrounding components, and is combined with the mounting frame 1 to form a closed structure, thereby facilitating the internal exhaust of the mounting frame 1, thereby realizing the negative pressure adsorption function, the threaded seat 102 can be connected to the threaded rod 303 and the limiting rod 302 at the same time, and then when the threaded rod 303 rotates, it can be limited by the limiting rod 302, so that the threaded seat 102 drives the bottom plate 105 and the components on its top to move horizontally; A printing plate 4 is mounted on the inner side of the mounting frame 1. A plurality of ventilation holes 402 are formed inside the printing plate 4, and an isolation cover 401 is fixedly mounted on the top of the printing plate 4. The printing plate 4 provides a printing position for the printing substrate, thereby printing the printing substrate into a three-dimensional shape according to a set program. The ventilation holes 402 allow air above the printing plate 4 to pass through the printing plate 4 and enter the mounting frame 1, thereby facilitating negative pressure adsorption of the printing substrate on top of the printing plate 4. The isolation cover 401 divides the space on top of the printing plate 4, thereby limiting the printing range of the printing substrate, preventing the printing substrate from being printed at the edge of the printing plate 4, and avoiding affecting the negative pressure adsorption effect of the device on the printing substrate. A driving assembly 5 is installed on the inner wall of the mounting frame 1 in the front-back direction. The driving assembly 5 can drive the sliding seat 7 and the crossbar assembly 6, so that the sliding seat 7 drives the crossbar assembly 6 to move horizontally; A sliding seat 7 is slidably mounted inside the driving assembly 5. The sliding seat 7 can reciprocate horizontally inside the driving assembly 5, thereby driving the crossbar assembly 6 to move horizontally, and can adjust the longitudinal position of the crossbar assembly 6 so as to realize different functions under different working conditions. A crossbar assembly 6 is mounted on one side of the sliding seat 7. The crossbar assembly 6 is adapted to fit against the bottom surface of the printing plate 4 and to move horizontally along the bottom of the printing plate 4, thereby clearing the ventilation holes 402 inside the printing plate 4 and ensuring the negative pressure adsorption effect of the device on the printed substrate. Furthermore, under the action of the sliding seat 7, the crossbar assembly 6 applies a vertical upward thrust to the printing plate 4, thereby assisting in rapid and non-destructive demolding of the printing plate 4. A fixing plate 2 is installed below the mounting frame 1, an air pump 202 is fixedly installed on the top of the fixing plate 2, and an air extraction pipe 201 is fixedly installed on the front side of the air extraction pump 202. The fixing plate 2 can be fixedly installed in a specified position by bolts to limit the bottom of the device and ensure the structural stability of the device as a whole. The air extraction pump 202 adopts AD5DB24 / 12D type. After the air extraction pump 202 is powered on, it can use the air extraction pipe 201 to extract air from the connecting pipe 103 and the suction cup 104, and then extract the air inside the mounting frame 1, so that a negative pressure environment is formed inside the mounting frame 1, and a negative pressure adsorption effect can be formed on the printing substrate on the top of the printing plate 4, thereby preventing the printing substrate from warping and shifting on the top of the printing plate 4. A U-shaped seat 3 is fixedly installed on both sides of the top of the fixed plate 2, and a threaded rod 303 and a limiting rod 302 are installed through the interior of the U-shaped seat 3. The U-shaped seat 3 can provide an installation position for the threaded rod 303 and the limiting rod 302. The threaded rod 303 can rotate and then cooperate with the threaded hole inside the threaded seat 102 to push the threaded seat 102 and the components on its top to move horizontally. The limiting rod 302 can limit the threaded seat 102, so that the threaded seat 102 can move stably horizontally along the limiting rod 302, thereby preventing the threaded seat 102 from flipping during movement.

[0020] Furthermore, the crossbar assembly 6 includes a sliding rod 601, with a card joint 604 provided at both ends of the sliding rod 601, a rubber ring 603 fixedly installed on the top of the sliding rod 601, the sliding rod 601 is a hollow rod, and the top of the sliding rod 601 is in contact with the bottom surface of the printing plate 4, a plurality of guide grooves 602 are provided on the top of the sliding rod 601, and the guide grooves 602 are long square grooves inclined at 45 degrees, a filter screen 605 is fixedly installed at the bottom position of the sliding rod 601, and the sliding rod 601 can be driven by the sliding seat 7 The sliding rod 601 can be moved horizontally, thereby driving the surrounding components to move horizontally. The card connector 604 can be connected with the card slot 701, thereby facilitating the installation and removal of the sliding rod 601. Under the pushing action of the paddle 704, the longitudinal position of the sliding rod 601 can be adjusted under the premise of ensuring the installation stability of the sliding rod 601. During the horizontal movement, the sliding rod 601 can continuously contact the bottom surface of the printing plate 4, thereby clearing the ventilation holes 402 inside the printing plate 4 to avoid clogging of the ventilation holes 402, thereby ensuring that the device is stable for printing. The negative pressure adsorption effect of the printing substrate is achieved. When the paddle 704 pushes the sliding rod 601 to move longitudinally, the sliding rod 601 can push the printing plate 4 to deform. At the same time, the sliding plate moves horizontally at the bottom of the printing plate 4, which can separate the bottom surface of the printing substrate from the printing plate 4, so as to facilitate the rapid demoulding of the printing substrate and ensure the integrity of the printing substrate during demoulding, thereby preventing damage to the printing substrate. The rubber ring 603 can improve the contact effect between the top of the sliding rod 601 and the printing plate 4 and reduce the wear rate of the top surface of the sliding rod 601. The guide groove 603 is provided with a plurality of guide grooves. 02 can guide the waste material sucked out of the ventilation hole 402 so that the waste material enters the interior of the sliding rod 601, and can achieve a cutting effect on the printing substrate extending out of the bottom surface of the printing plate 4, and then suck out the printing substrate blocked in the ventilation hole 402 to clear the ventilation hole 402. The filter screen 605 can make the printing substrate fall into the interior of the sliding rod 601 for centralized storage without affecting the air circulation, which is convenient for centralized cleaning after the equipment is used, and prevents waste material from entering the interior of the vacuum pump 202 and causing damage to the vacuum pump 202.

[0021] Furthermore, a card slot 701 is provided on the side of the sliding seat 7 facing the crossbar assembly 6, and the card slot 701 is a U-shaped slot composed of three protrusions. A number of ball bearings 702 are mounted on the top and bottom of the sliding seat 7. Motors 703 are fixedly mounted on both sides of the interior of the sliding seat 7, and the output shaft of the motor 703 extends to one side of the sliding seat 7 and a paddle 704 is mounted. The card slot 701 can cooperate with the card joint 604 to quickly install and remove the sliding rod 601. The ball bearings 702 can reduce the friction between the sliding seat 7 and the guide rail groove 501 to facilitate the movement of the sliding seat 7. The motor 703 adopts the DT42BL50-230 model. The motor 703 can rotate after being energized. The paddle 704 is driven to rotate. After the rotation, the paddle 704 can contact the side of the card joint 604 and apply a thrust to the card joint 604, so that the card joint 604 drives the sliding rod 601 to move longitudinally, and then the longitudinal position of the sliding rod 601 is adjusted, so that the sliding rod 601 applies a thrust to the printing plate 4 to cause a small deformation, and then when the sliding rod 601 moves back and forth horizontally, the printing plate 4 can be deformed in a wave shape, and the printing substrate on the top of the printing plate 4 can be quickly demolded. When the motor 703 rotates in the opposite direction, the paddle 704 can be separated from the card joint 604, so that under the action of gravity and the reverse force applied by the printing plate 4, the sliding rod 601 is restored to its original position.

[0022] Furthermore, the driving component 5 includes a guide rail groove 501, and a plurality of slide grooves 502 are opened on the inner walls of the upper and lower sides of the guide rail groove 501. A mounting bracket 506 is fixedly installed at the bottom of the guide rail groove 501, and a servo motor 505 is fixedly installed on one side of the mounting bracket 506. A screw rod 504 is fixedly installed on the output shaft of the servo motor 505. The screw rod 504 is connected to the mounting bracket 506 through a bearing. A connecting seat 503 is installed on the outer side of the screw rod 504 through a threaded structure, and the connecting seat 503 is connected to the sliding seat 7. The guide rail groove 501 can limit the sliding seat 7 so that the sliding seat 7 is fixed in the guide rail groove. The interior of 501 moves stably horizontally, and the slide groove 502 can engage with the ball 702, thereby further limiting the sliding seat 7 and improving the stability of the sliding seat 7 during horizontal movement. The mounting bracket 506 can provide an installation position for the screw rod 504 and the servo motor 505. The servo motor 505 adopts the HS5776 type. After the servo motor 505 is powered on, it can drive the screw rod 504 to rotate. The screw rod 504 can cooperate with the internal thread of the connecting seat 503 during rotation to move the connecting seat 503 horizontally, thereby making the connecting seat 503 drive the sliding seat 7 to move horizontally synchronously.

[0023] Furthermore, two fixing buckles 101 are rotatably installed on both sides of the top of the mounting frame 1, and ventilation slots 106 are opened on the left and right sides of the mounting frame 1. Suction cups 104 are fixedly installed on the left and right sides of the mounting frame 1. The fixing buckles 101 can limit the top of the printing plate 4, thereby ensuring the installation stability of the printing plate 4. The ventilation slots 106 can connect the suction cup 104 with the interior of the mounting frame 1 to facilitate the suction of the air inside the mounting frame 1. The suction cup 104 can be connected through the connecting pipe 103, thereby facilitating the exhaust pipe 201 to suck the air inside the suction cup 104 and the mounting frame 1.

[0024] Furthermore, a screw motor 301 is fixedly installed on the front side of the U-shaped seat 3, and the output shaft of the screw motor 301 is fixedly connected to one end of the threaded rod 303. The threaded rod 303 and the limit rod 302 respectively pass through the interior of the threaded seat 102. The screw motor 301 adopts the YE4-100KW type. After the screw motor 301 is energized, it can drive the threaded rod 303 to rotate, so that the threaded rod 303 drives the threaded seat 102 to move horizontally.

[0025] Furthermore, support rods are fixedly installed on both sides of the bottom of the printing plate 4, and the support rods are connected to the top of the base plate 105. The support rods can support the bottom of the printing plate 4 and maintain a certain distance between the printing plate 4 and the base plate 105 to facilitate air circulation between the printing plate 4 and the base plate 105.

[0026] Furthermore, a connecting tube 103 is fixedly installed between the suction cups 104, and the connecting tube 103 is fixedly connected to the exhaust pipe 201. The connecting tube 103 can be connected to the exhaust pipe 201 and the suction cups 104, thereby facilitating the exhaust pump 202 to suck the air inside the suction cups 104, thereby exhausting the air inside the mounting frame 1, and causing the device to form a negative pressure adsorption effect on the printing substrate on the top of the printing plate 4.

[0027] Working principle: After the device is assembled, put the printing plate 4 into the installation frame 1, and rotate the fixing buckle 101 to fix the printing plate 4. The screw motor 301 drives the threaded rod 303 to rotate, so that the threaded seat 102 drives the assembly on its top to move to the specified position, and the printing substrate gradually falls on the top of the printing plate 4 for 3D printing. At the same time, the air pump 202 sucks the air inside the installation frame 1, so that the printing substrate is stably adsorbed on the printing plate 4 by the negative pressure adsorption force and gradually cools and takes shape. The driving assembly 5 drives the sliding seat 7 to move back and forth horizontally, thereby driving the crossbar assembly 6 to move horizontally. Component 6 contacts the bottom surface of the printing plate 4 and continuously cleans the printing substrate inside the ventilation hole 402, so that the ventilation hole 402 inside the printing plate 4 remains unobstructed, ensuring the device's adsorption effect on the printing substrate. After printing is completed, the motor 703 drives the paddle 704 to rotate, and the paddle 704 pushes the card joint 604 and the sliding rod 601 to move longitudinally, so that the sliding rod 601 pushes the printing plate 4 to deform. At the same time, the driving component 5 drives the cross bar component 6 to move back and forth horizontally again, so that the printing plate 4 is deformed in a wave shape under the push of the cross bar component 6, so that the printing substrate is separated from the printing plate 4 and the demolding is completed.
