Description

Technical Field

[0001] The present invention relates to the technical field of balance detection, and in particular to a self-test device for a flexible electronic 3D printing device. Background Art

[0002] A slight deviation in the movement trajectory of the nozzle in a flexible electronic 3D printing device can lead to misalignment between layers or uneven material accumulation, which directly affects the dimensional tolerance of the printed part, and the nozzle movement speed and extrusion rate need to be dynamically matched. If the movement is unstable, it will cause the molten material to be cut off or over-extruded, resulting in cavities or tumor-like defects. When printing overhanging structures or hollow grids (such as biomedical stents), nozzle jitter will cause the support point to shift, resulting in a 3-4 times increase in the risk of cross-layer collapse. Therefore, it is necessary to use the built-in self-test equipment to regularly detect and process the movement stability of the nozzle part.

[0003] In the existing technology, the process of detecting the movement balance of the nozzle part in the flexible electronic 3D printing device is to directly mount a vibration sensor component on the nozzle. However, since the nozzle part is always in a high-speed moving state, the vibration sensor will be disturbed by its moving state, resulting in low detection accuracy and prone to errors. On the other hand, when the nozzle produces high-frequency shaking during movement, the conventional detection scheme cannot obtain its vibration offset direction, so the detection result is not accurate enough. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a self-inspection device for a flexible electronic 3D printing device to solve the problems raised in the above background technology. The present invention controls the balance detection module to move along the guide track by moving the nozzle, and detects the movement stability of the nozzle through the detection box at the rear end during the movement. This structure can eliminate the interference of the nozzle on the detection result when it moves along a straight line, thereby improving the accuracy and reliability of the detection. At the same time, it can also detect the uniformity of the nozzle's spraying and realize efficient repeated detection.

DETAILED DESCRIPTION

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0028] See also Figures 1 to 7The present invention provides the following technical solution: a self-test device for a flexible electronic 3D printing device, comprising a self-test device body and a print head 32, the self-test device body comprising a printing platform 1, a guide rail 2, a balance detection module 3, and a drive mechanism 4. The surface of the printing platform 1 is provided with an arcuate groove 16, the guide rail 2 is welded to the top of the printing platform 1, and a self-test interlayer 8 is provided in the middle of the guide rail 2, the self-test interlayer 8 is provided above the arcuate groove 16, the balance detection module 3 is mounted on the surface of the guide rail 2, the rear end of the balance detection module 3 is integrally formed with a detection box 19, and a detection cavity 31 is defined within the detection box 19, the bottom of the printing platform 1 is provided with a drive mechanism 4, the drive mechanism 4 passes through the interior of the arcuate groove 16, the print head 32 is mounted above the printing platform 1, and the print head 32 is controlled and driven by the printer's own axis shift system to dock with the top of the balance detection module 3, and the bottom of the print head 32 is aligned with the middle position of the arcuate groove 16. The self-test device is built on the printing platform 1 in the 3D printer to test the stability of the printing nozzle 32 during translation.

[0029] When the present invention is used, the guide rail 2 is installed on the surface of the printing platform 1. During the printing process, when the print head 32 needs to be self-tested, the printer's built-in shift system controls the print head 32 to move to the top of the guide rail 2 and moves the print head 32 downward until it docks with the balance detection module 3. At this time, the print head 32 can be controlled to move along the guide rail 2. During the movement, the photosensitive module 28 inside the rear detection box 19 is used to detect whether the print head 32 has any longitudinal swing during its movement. At the same time, while controlling the movement of the print head 32, the printing material is ejected downward from the bottom of the print head 32, forming a dotted straight line on the receiving column 15. The distribution of the ejected material is identified and detected by the industrial camera 21, further obtaining the stability of the print head 32 during its movement and the consistency of the material spraying.

[0030] In this embodiment, the guide rail 2 includes a front baffle 5, a rear end plate 6 and a support plate 7. The outer side of the front baffle 5 is integrally formed with an extension plate 11, and the surface of the extension plate 11 is embedded with a first magnetic plate 13. The surface of the front baffle 5 is provided with a strip hole 12, and the surface of the support plate 7 is embedded with a light source 9 and a fixed partition 10. There are two light sources 9, each of which is a strip-shaped structure. The two light sources 9 are respectively installed on both sides of the fixed partition 10, and the support plate 7 is integrally formed at the top of the rear end plate 6. The front baffle 5 and the rear end plate 6 are both welded to the surface of the printing platform 1, and the self-test interlayer 8 is opened between the front baffle 5 and the rear end plate 6. The surface of the support plate 7 is flush with the top of the front baffle 5, and the first magnetic plate 13 is set at one end of the extension plate 11. By controlling the nozzle to move linearly within the guide track 2, the nozzle is made to spray material at a uniform speed. In conjunction with the rear-end visual system, the continuity and uniformity of the material sprayed on the bottom can be collected. With the help of this solution, more intuitive stability test results can be obtained, thereby achieving the purpose of detecting the uniformity of the nozzle's spraying.

[0031] Specifically, after the print head 32 is moved downward, it will first be embedded in the interior of the balance detection module 3, and the balance detection module 3 will be driven to move synchronously through the movement of the print head 32. During this process, the bottom of the print head 32 is always aligned with the receiving column 15 below, so that the print head 32 can be controlled to continuously spray the coating material onto the surface of the receiving column 15, and with the help of the industrial camera 21, whether the distribution of the material sprayed from the bottom is uniform is collected to achieve the purpose of whether the movement process and the spraying process of the print head 32 are stable.

[0032] In this embodiment, the balance detection module 3 includes a detection box 19, a transmission frame 20, and a limit plate 25. The detection box 19 is integrally formed at the rear end of the transmission frame 20. A positioning plate 22 is welded to the top of the transmission frame 20. A positioning hole 23 is provided in the middle of the positioning plate 22. Third magnetic plates 24 are attached to both sides of the positioning plate 22. A movable partition 29 is embedded in the interior of the detection box 19. Enclosures 30 are integrally formed at both ends of the movable partition 29. A photosensitive module 28 is embedded at the top of the inner wall of the detection box 19. A pressing plate 33 is screwed to the top of the print head 32. A fourth magnetic plate 34 is attached to the side of the pressing plate 33. The print head 32 is used to pass through the interior of the positioning hole 23. The pressing plate 33 is used to fit the surface of the positioning plate 22. The fourth magnetic plate 34 is used to attract and fit the third magnetic plate 24. A limit plate 25 is welded to the bottom front end of the transmission frame 20. A second magnetic plate 27 is attached to the bottom of the limit plate 25, which is designed to engage with the first magnetic plate 13. A telescopic sleeve 26 is threaded onto the surface of the limit plate 25, and a spring rod 35 is inserted into the interior of the telescopic sleeve 26. A roller 36 is mounted on the end of the spring rod 35. The bottom of the transmission frame 20 passes through the interior of the strip hole 12. An industrial camera 21 is threaded onto the bottom end of the transmission frame 20. The limit plate 25 is pressed against the surface of the extension plate 11 via the second magnetic plate 27 at the bottom, and the roller 36 is pressed against the surface of the front baffle 5 via the spring rod 35. The balance detection module 3 is controlled by the mobile nozzle to move along the guide rail 2. During this movement, the nozzle's movement stability is detected by the detection box 19 at the rear end. This structure eliminates interference with the detection results caused by the nozzle's linear motion, thereby improving the accuracy and reliability of the detection.

[0033] Specifically, in the initial state, the balance detection module 3 is at the end of the extension plate 11, and with the help of the second magnetic plate 27 and the first magnetic plate 13 at the bottom for adsorption and adhesion, the initial position of the entire balance detection module 3 can be positioned. After the print head 32 is moved downward, the print head 32 will be embedded in the interior of the positioning hole 23, and when the print head 32 is controlled to move horizontally, the print head 32 can be used to push the positioning plate 22 to move the entire balance detection module 3 along the guide rail 2. During this process, if the print head 32 always keeps moving smoothly, the movable partition 29 inside the transmission compartment is always aligned with the fixed partition 10 at the bottom, so that the two light sources 9 will always directly illuminate the interior of the detection cavity 31. , and detected by the photosensitive module 28 at the bottom. When the print head 32 is not balanced enough and shakes, the detection chamber at the rear end of the transmission frame 20 can be driven to move horizontally. At this time, the movable partition 29 is offset to one side, blocking one of the light sources 9. The signal of the light source 9 received by the photosensitive module 28 can be changed, so as to judge that the current movement process of the print head 32 is shaking, and according to the frequency and degree of signal changes of the two photosensitive modules 28, the direction in which the print head 32 is offset can be judged. During the movement, the roller 36 is always pressed against the front baffle 5 by the spring rod 35, and the adsorption effect between the third magnetic plate 24 and the fourth magnetic plate 34 is combined to ensure that the entire balance detection module 3 does not rotate.

[0034] In this embodiment, the drive mechanism 4 includes a motor 14 and a receiving column 15. The motor 14 is screwed to the end of the printing platform 1. The receiving column 15 is connected to the output shaft of the motor 14 via a coupling. A notch 17 is provided at the bottom of the arcuate groove 16. A scraper bar 18 is mounted on the inner wall of the arcuate groove 16. The bottom of the scraper bar 18 is aligned with the edge of the notch 17. The top of the scraper bar 18 rests on the surface of the receiving column 15. The print head 32 sprays the printing material onto the surface of the receiving column 15. The receiving column 15, whose bottom receives the sprayed material, is controlled to rotate by the drive mechanism 4. Therefore, after each movement and detection, the sprayed material can be quickly rotated and scraped off, thereby achieving an efficient and repeated detection process.

[0035] Specifically, the material sprayed out of the print head 32 is received by the inner receiving column 15, and the print head 32 moves from one end to the other along the self-test interlayer 8 to complete a single test. After completing a single test, the motor 14 is started, and the receiving column 15 is driven to rotate by the motor 14, and then the material sprayed on the receiving column 15 is scraped off by the scraper 18 at the bottom, and the movement of the print head 32 can be controlled again, and the above-mentioned spraying detection process is repeated again.
