Description

Technical Field

[0001] This utility model relates to the field of 3D printing equipment technology, specifically to a 3D printing time-lapse photography triggering device. Background Technology

[0002] With the rapid development of 3D printing technology, FDM (Fused Deposition Modeling) 3D printers have become a widely used printing device. Their technical characteristic lies in constructing three-dimensional objects by layering molten thermoplastic material. FDM 3D printers, often referred to as gantry 3D printers, are popular due to their stable structure and ease of operation. While pursuing efficient and high-quality printing, users' demand for visualization of the printing process is also increasing. Time-lapse photography during the printing process has emerged as a result, recording and displaying the entire 3D printing process, providing users with a unique visual experience.

[0003] Currently, some FDM 3D printers on the market are equipped with built-in time-lapse photography functionality, but a large number of existing devices still lack this feature. For these 3D printers without time-lapse photography, users typically need to modify them to achieve this function. The existing modification methods are roughly as follows: First, a mobile phone is fixedly installed in front of the 3D printer as a camera; second, a trigger switch is set at the X-axis origin of the printer, connected to the mobile phone, to trigger the phone to take a picture at a specific moment. To implement the photo-taking function, the user also needs to add a specific code segment to the existing printing G-code. This code segment instructs the print head to return to the origin after each layer is printed, thus triggering the switch to take a picture. Throughout the printing process, the mobile phone will capture the printing status of each layer until printing is complete. The user then exports all the captured photos and combines them into a complete video.

[0004] However, while this modification method satisfies users' needs for time-lapse photography during the printing process to some extent, it also exposes some obvious drawbacks. Because a printhead return-to-origin instruction needs to be added to the existing G-code, the printhead needs to move back to the origin after each layer of printing to initiate the photographing process. This not only increases the printhead's travel distance but also prolongs the entire printing cycle. More seriously, although filament extrusion stops before the printhead returns to the origin, due to the characteristics of thermoplastic materials, especially when using poor-quality or damp filaments, noticeable stringing may still occur. This not only affects printing efficiency but may also adversely impact the quality of the final printed product.

[0005] Therefore, how to add time-lapse photography functionality while avoiding additional printhead movement and potential stringing has become an urgent problem to be solved in the current FDM 3D printer time-lapse photography modification technology. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a 3D printing time-lapse photography trigger device to overcome the shortcomings of the prior art.

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A 3D printing time-lapse photography trigger device includes a housing, a displacement sensor and a telescopic mechanism. A placement slot for accommodating the control button of a wired earphone with a photo-taking function is provided on one side of the housing. The telescopic mechanism is located above the placement slot for touching the control button. A clamp for fixing the housing on the X-axis of the 3D printer is provided on the housing. The displacement sensor is located on the housing and faces the Y-axis of the 3D printer. Both the displacement sensor and the telescopic mechanism are electrically connected to the controller.

[0008] The beneficial effects of this invention are as follows: Before printing, the 3D printer needs to slice the drawing. During the slicing process, the layer height is set. After each layer is printed, the Y-axis motor starts once, driving the X-axis and the print head to move upward along the Y-axis. By detecting the rise of the X-axis of the 3D printer in the Y-axis direction through the displacement sensor, it can be indicated that one layer has been printed. At this time, a signal is sent to the telescopic mechanism. The telescopic end of the telescopic mechanism extends and touches the control button, thereby triggering the mobile phone to take a picture. This device does not require modification of G-code and does not require the print head to return to the origin, which not only ensures the original printing speed and efficiency, but also does not reduce the printing quality due to stringing. In addition, the use of existing mobile phones and wired headphones with camera function realizes the taking of pictures during the 3D printing process, reducing the research and development and production costs.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, the displacement sensor is a grating sensor.

[0011] Furthermore, it also includes an extension rod and a mounting block. The displacement sensor is mounted on the mounting block. One end of the extension rod is rotatably connected to one side of the housing via a damping shaft, and the mounting block is rotatably connected to the other end of the extension rod via a damping shaft.

[0012] Furthermore, a storage groove for accommodating the extension rod and mounting block is provided on one side of the housing.

[0013] Furthermore, a U-shaped spring is installed inside the slot.

[0014] Furthermore, a storage battery is installed inside the housing, and a charging interface electrically connected to the storage battery is provided on the housing. Both the storage battery and the charging interface are electrically connected to the controller.

[0015] Furthermore, the telescopic mechanism is a miniature linear cylinder. Attached Figure Description

[0022] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0023] like Figures 1-4 As shown in Embodiment 1, a 3D printing time-lapse photography trigger device includes a housing 1, a displacement sensor 2, and a telescopic mechanism 3. One side of the housing 1 is provided with a placement slot 11 for accommodating the control button 4 of a wired earphone with a photo-taking function. The telescopic mechanism 3 is located above the placement slot 11 for touching the control button 4. The housing 1 is provided with a clamp 5 for fixing the housing 1 on the X-axis 8 of the 3D printer. The displacement sensor 2 is located on the housing 1 and faces the Y-axis 9 of the 3D printer. Both the displacement sensor 2 and the telescopic mechanism 3 are electrically connected to the controller.

[0024] Before printing, the 3D printer needs to slice the drawing. During the slicing process, the layer height is set. After each layer is printed, the Y-axis motor starts once, driving the X-axis 8 and the print head to move upward along the Y-axis 9. The displacement sensor 2 detects the rise of the 3D printer's X-axis 8 in the Y-axis 9 gantry direction, which indicates that one layer has been printed. At this time, a signal is sent to the telescopic mechanism 3. The telescopic end of the telescopic mechanism 3 extends and touches the control button 4, thereby triggering the mobile phone to take a picture. This device does not require modification of G-code and does not require the print head to return to the origin, which ensures the original printing speed and efficiency, while also preventing the reduction of print quality due to stringing. In addition, the use of existing mobile phones and wired headphones with camera function realizes the taking of pictures during the 3D printing process, reducing research and development and production costs.

[0025] In practice, the clamp 5 uses a clamp plate with conventional bolt adjustment, which can be adapted to profiles of different thicknesses. In addition, the controller uses a conventional STM32 or ESP8266 control board.

[0026] Example 2 is a further improvement based on Example 1, and its details are as follows:

[0027] Displacement sensor 2 is a grating sensor. In practice, the existing built-in grating sensor of the mouse is used, which makes displacement detection more accurate. In addition, in order to avoid detection errors caused by the excessive smoothness of the surface of Y-axis 9 (gantry), masking tape can be applied to the surface of the gantry during actual use.

[0028] Example 3 is a further improvement based on Example 2, and its details are as follows:

[0029] It also includes an extension rod 6 and a mounting block 7. The displacement sensor 2 is mounted on the mounting block 7. One end of the extension rod 6 is rotatably connected to one side of the housing 1 via a damping shaft, and the mounting block 7 is rotatably connected to the other end of the extension rod 6 via a damping shaft. By adjusting the extension rod 6 and the mounting block 7, the grating sensor can be made to fit more closely to the Y-axis 9 (gantry) of the 3D printer, resulting in more accurate displacement detection.

[0030] Example 4 is a further improvement on Example 3, and its details are as follows:

[0031] A storage slot 12 is provided on one side of the housing 1 to accommodate the extension rod 6 and the mounting block 7. When not in use, the extension rod 6 and the mounting block 7 can be rotated into the storage slot 12, which can protect the extension rod 6 and the grating sensor, reduce the space occupied, and facilitate storage.

[0032] Example 5 is a further improvement based on Example 1, and its details are as follows:

[0033] A U-shaped spring 13 is provided in the placement slot 11. Because the U-shaped spring 13 is elastic, it can clamp the control button 4 of wired headphones of different thicknesses, thus making it more compatible.

[0034] Example 6 is a further improvement based on Example 1, and its details are as follows:

[0035] A battery is installed inside the housing 1, and a charging interface electrically connected to the battery is provided on the housing 1. Both the battery and the charging interface are electrically connected to the controller. No external power supply line is required, making it more convenient to use.

[0036] Example 7 is a further improvement based on Example 1, and its details are as follows:

[0037] The telescopic mechanism 3 is a miniature linear cylinder. This greatly reduces the overall size of the device. In practice, a spring pin is connected to the telescopic end of the miniature linear cylinder, which can play a buffering role and thus effectively protect the control buttons 4 of the wired headphones.

[0038] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
