[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, 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.

[0025] Currently, many 3D printers require inserting the 3D printing filament into the extruder when used for the first time or when changing to different types or brands of filament. The filament is then manually adjusted using the extruder screws to control the tightness of the filament clamped by the extrusion gears, aiming for smooth, unobstructed filament extrusion. For many novice or inexperienced 3D printer users, it's difficult to determine if the clamping force of the extrusion gears is just right. Furthermore, different brands have different tolerance requirements for filament diameter, resulting in uneven filament diameters, which further complicates adjusting the extruder clamping force. If the gear engagement force with the filament is too weak, the filament will get stuck between the extruder teeth. Slippage within the gear prevents smooth material extrusion. If the meshing force of the gears on the filament is too great, the filament will deform due to excessive clamping force, potentially becoming segmented wavy shapes. This increases the resistance within the Teflon conduit during the transmission of the filament to the hot end. All these factors affect the smoothness of the filament extrusion from the nozzle after heating at the hot end, resulting in a significant decrease in the surface quality of the printed model, leading to discontinuous, rough, and void-filled surfaces. Therefore, the automatic detection and control method for filament filling provided in this invention reduces the difficulty of adjusting the filament during the filling process and significantly improves adjustment accuracy.

[0026] See Figure 1 The diagram shows an automatic detection and control method for filament filling. This method is applied to a 3D printer, which is equipped with a feeding end and a guide tube. The method mainly includes the following steps S102 to S106:

[0027] Step S102: When the consumable filament is detected to be transferred to the feeding end, the transfer gear is controlled to rotate to transfer the consumable filament to the guide tube. One end of the consumable filament is fixed to the transfer gear. The feeding end is equipped with a transfer gear, an adjusting screw, a spring, and a micro motor. The adjusting screw is connected to the spring and the micro motor respectively. In one embodiment, the rotation direction of the adjusting screw is adjusted by the micro motor. When the micro motor rotates counterclockwise, the spring pressure decreases, the adjusting screw is loosened, and the biting force of the transfer gear decreases. When the micro motor rotates clockwise, the spring pressure increases, the adjusting screw is tightened, and the biting force of the transfer gear increases. In another embodiment, the transfer gear is used to fix the consumable filament with a suitable biting force so that the consumable filament will not deform due to excessive biting force of the transfer gear, nor will it slip due to insufficient biting force of the transfer gear. After the consumable filament is fixed, the transfer gear is rotated to move the consumable filament to the guide tube.

[0028] Step S104: During the rotation of the transmission gear, the transmission gear and the guide tube are monitored to obtain monitoring information. The monitoring information includes the meshing force of the transmission gear and the diameter of the consumable wire in the guide tube. In one embodiment, the monitoring information can be obtained by a pressure sensor and a vision sensor. The monitoring information can be sent to a server, processed by a preset algorithm to generate a control signal, and the control signal is fed back to the micro motor so that the micro motor controls the adjusting screw to adjust the meshing state of the transmission gear.

[0029] Step S106: Adjust the meshing state of the transmission gear according to the monitoring information to determine the target meshing state, and control the transmission gear to continue to transmit the filament to the guide tube in the target meshing state so as to perform 3D printing based on the filament in the guide tube. In one embodiment, the transmission gear can be coarsely adjusted using the pressure value obtained by the pressure sensor and finely adjusted using the filament diameter obtained by the vision sensor. The fine adjustment process can be repeated multiple times.

[0030] The automatic detection and control method for filling consumable filaments provided in this embodiment of the invention can reduce the difficulty of adjusting consumable filaments during the filling process and significantly improve the adjustment accuracy.

[0031] This invention also provides an implementation method for detecting and controlling the working state of the transmission gear. The 3D printer is also equipped with a detection and control module, which includes a pressure sensor and a vision sensor, as detailed in (1) to (3) below:

[0032] (1) The pressure value of the spring is detected by a pressure sensor. When the pressure value is greater than the preset pressure threshold, it is determined that the meshing force of the transmission gear on the consumable wire is too tight. When the pressure value is less than the preset pressure threshold, it is determined that the meshing force of the transmission gear on the consumable wire is too loose. When the pressure value is within the preset pressure threshold range, it is determined that the meshing force of the transmission gear on the consumable wire is normal and the first-level test is passed. In one embodiment, the first-level test is to coarsely adjust the transmission gear. The pressure threshold is a preset threshold that can be set according to the different tolerance requirements of different brands for the diameter of the consumable wire.

[0033] (2) The diameter of the consumable filament in the feed tube is detected by a vision sensor. When the diameter of the consumable filament in the feed tube is less than the preset diameter threshold, it is determined that the biting force of the transmission gear on the consumable filament is too tight. When the diameter of the consumable filament in the feed tube is greater than the preset diameter threshold, it is determined that the biting force of the transmission gear on the consumable filament is too loose. When the diameter of the consumable filament in the feed tube is within the preset diameter threshold range, it is determined that the biting force of the transmission gear on the consumable filament is normal, and the secondary detection is passed. In one embodiment, after the consumable filament is extruded by the gear, it will be guided to the hot end through the feed tube. By opening a window in the feed tube for vision detection, the biting force of the extruder gear can be further fine-tuned: the vision detection camera will record the consumable filament passing through in real time and calculate the diameter of this section of consumable filament through the algorithm, thereby fine-tuning the biting force of the transmission gear and completing the secondary detection.

[0034] (3) Using a preset control calculation model, based on monitoring information, determine the adjustment strategy of the transmission gear, adjust the meshing state of the transmission gear according to the adjustment strategy, and determine the target meshing state. The adjustment strategy includes the rotation direction and number of rotations of the micro motor. In one embodiment, when the meshing force of the transmission gear on the consumable wire is too tight, control the micro motor to rotate counterclockwise by the corresponding number of rotations to reduce the meshing force of the transmission gear. When the meshing force of the transmission gear on the consumable wire is too loose, control the micro motor to rotate clockwise by the corresponding number of rotations to increase the meshing force of the transmission gear. In one embodiment, the monitoring information can be sent to the server, processed by the preset control calculation model in the server to generate a control signal, and the control signal is fed back to the micro motor in the form of an electrical signal, so that the micro motor controls the adjustment screw to adjust the meshing state of the transmission gear, thereby achieving fast and accurate automatic adjustment.

[0035] In one embodiment, the detection control module further includes a material breakage detection sensor. When the material breakage detection sensor enters the trigger state, it is determined that the filament filament is successfully loaded. After the 3D printer is started, the material breakage detection sensor is first used to detect whether the filament filament is successfully loaded. When the filament filament is successfully loaded, the nozzle and heated bed are preheated at a specified temperature. After the specified temperature is reached, the extruder starts working and drives the filament filament by engaging the transmission gear.

[0036] To facilitate understanding of the automatic detection and control method for consumable filament filling provided in the above embodiments, this invention provides an application example of the automatic detection and control method for consumable filament filling, see [link to example]. Figure 2 The diagram shows another automatic detection and control method for filament filling, which mainly includes the following steps S202 to S206:

[0037] Step S202: When the filament filling is successfully detected, the filament is sent to the feeding end. In one embodiment, after the 3D printer is started, the system loads the sliced ​​STL format 3D printing file. First, the material breakage detection sensor detects whether the filament is successfully filled. If the filament is successfully filled, the printer will preheat the nozzle and heated bed at the specified temperature. After the specified temperature is reached, the extruder starts to work, and its gears will mesh with the filament to rotate, sending the filament to the heated end.

[0038] Step S204: Using feedback information from the pressure sensor, the operating state of the transmission gear is coarsely adjusted. In one embodiment, see [link to implementation details]. Figure 3 The diagram shows an overall flow chart of an automatic detection and control method for refilling consumable filaments. The engagement of the gears is controlled by adjusting the tightness of a screw with a spring. If the pressure sensor detects that the spring pressure is greater than the threshold, it is determined that the gears are engaging the consumable filaments too tightly. The micro motor then starts to rotate counterclockwise to loosen the adjusting screw and release the gear engagement force. If the pressure sensor detects that the spring pressure is less than the threshold, it is determined that the gears are engaging the consumable filaments too loosely. The micro motor then starts to rotate clockwise to tighten the adjusting screw and increase the gear engagement force.

[0039] Step S206: Using feedback information from the vision sensor, the working state of the transmission gear is fine-tuned, and 3D printing is performed after the debugging is completed. In one embodiment, after the filament is extruded by the gear, it is guided to the hot end through the guide tube. By opening a window in the guide tube for vision inspection, the biting force of the extruder gear can be further fine-tuned: The vision inspection camera records the filament passing through in real time and calculates the diameter of this section of filament through the algorithm. If the extrusion diameter is less than the threshold, it is determined that the gear is biting the filament too tightly, and the micro motor starts to rotate counterclockwise to loosen the adjusting screw and release the gear biting force. If the extrusion diameter is greater than the threshold, it is determined that the gear is biting the filament too loosely, and the micro motor starts to rotate clockwise to tighten the adjusting screw and increase the gear biting force. In another embodiment, after repeating the fine-tuning process, when the detected diameter is within the threshold range, the extruder adjustment is completed, and the extruder continues to feed the filament into the hot end to start normal printing of the 3D model.

[0040] In summary, the present invention can reduce the difficulty of adjusting the consumable filament during the filling process and significantly improve the adjustment accuracy.

[0041] Regarding the automatic detection and control method for filament filling provided in the foregoing embodiments, this invention provides an automatic detection and control device for filament filling. This device is applied to a 3D printer. The 3D printer is equipped with a feeding end and a guide tube. The feeding end is provided with a transmission gear. See [link to relevant documentation]. Figure 4The diagram shows an automatic detection and control device for the filling of consumable filaments. The device includes the following parts:

[0042] The consumable filling module 402 controls the transmission gear to rotate when it detects that the consumable filament is being passed to the feeding end, so as to pass the consumable filament to the guide tube; wherein, one end of the consumable filament is fixed to the transmission gear;

[0043] The detection module 404 monitors the transmission gear and the guide tube during the rotation of the transmission gear to obtain monitoring information; the monitoring information includes: the meshing force of the transmission gear and the diameter of the consumable wire in the guide tube;

[0044] The control module 406 adjusts the meshing state of the transmission gear according to the monitoring information to determine the target meshing state, and controls the transmission gear to continue to transmit the filament to the guide tube in the target meshing state, so as to perform 3D printing based on the filament in the guide tube.

[0045] The data processing device provided in this application embodiment can save users trial and error costs and time by quickly adjusting the meshing of the extruder gears, thereby improving the 3D printer experience. By optimizing the smoothness of filament extrusion, the extruded filament has a uniform diameter and appropriate thickness. The stability of the molten filament flow through the hot end and nozzle is better, and the surface of the molded and stacked model will be neat. This solves the problems of surface texture, pores, bumps and other phenomena caused by unstable flow, thereby improving the printing quality.

[0046] In addition, this device can adjust the extruder to the optimal extrusion gripping force in a short time, solving the problem that existing methods for adjusting the extrusion gear gripping force in 3D printers are difficult to achieve the best output state in one go and require multiple attempts. It also addresses the issue that after a period of use, the screws of various components will loosen due to vibrations during the printer's operation (the adjusting screws of the extruder often need to be manually adjusted after a period of use because thread-locking adhesive cannot be applied to them), thus significantly reducing the frequency of repetitive work.

[0047] In one embodiment, the feeding end further includes an adjusting screw, a spring, and a micro motor. The adjusting screw is connected to the spring and the micro motor respectively. The control module 406 is also used to: adjust the rotation direction of the adjusting screw through the micro motor; when the micro motor rotates counterclockwise, the spring pressure decreases, the adjusting screw is loosened, and the meshing force of the transmission gear decreases; when the micro motor rotates clockwise, the spring pressure increases, the adjusting screw is tightened, and the meshing force of the transmission gear increases.

[0048] In one embodiment, the 3D printer is further equipped with a detection control module, which includes a pressure sensor. During the step of monitoring the transmission gear and the feed tube to obtain monitoring information during the rotation of the transmission gear, the detection module 404 is also used to: perform a first-level detection on the pressure value of the spring using the pressure sensor; when the pressure value is greater than a preset pressure threshold, it is determined that the biting force of the transmission gear on the filament is too tight; when the pressure value is less than the preset pressure threshold, it is determined that the biting force of the transmission gear on the filament is too loose; when the pressure value is within the preset pressure threshold range, it is determined that the biting force of the transmission gear on the filament is normal, and the first-level detection is passed.

[0049] In one embodiment, the detection control module further includes a vision sensor. The detection module 404 is also used to: perform secondary detection on the diameter of the consumable filament in the feed tube using the vision sensor; when the diameter of the consumable filament in the feed tube is less than a preset diameter threshold, determine that the biting force of the transmission gear on the consumable filament is too tight; when the diameter of the consumable filament in the feed tube is greater than the preset diameter threshold, determine that the biting force of the transmission gear on the consumable filament is too loose; when the diameter of the consumable filament in the feed tube is within the preset diameter threshold range, determine that the biting force of the transmission gear on the consumable filament is normal, and the secondary detection passes.

[0050] In one embodiment, when performing the step of adjusting the meshing state of the transmission gear according to the monitoring information to determine the target meshing state, the detection module 404 is further configured to: use a preset control calculation model to determine the adjustment strategy of the transmission gear based on the monitoring information, wherein the adjustment strategy includes: the rotation direction and number of rotations of the micro motor; adjust the meshing state of the transmission gear according to the adjustment strategy to determine the target meshing state.

[0051] In one embodiment, the detection module 404 is further configured to: when the meshing force of the transmission gear on the consumable filament is too tight, control the micro motor to rotate counterclockwise by the corresponding number of rotations to reduce the meshing force of the transmission gear; when the meshing force of the transmission gear on the consumable filament is too loose, control the micro motor to rotate clockwise by the corresponding number of rotations to increase the meshing force of the transmission gear.

[0052] In one embodiment, the detection control module further includes a material breakage detection sensor, and the detection module 404 is also used to determine that the consumable filament is successfully filled when the material breakage detection sensor enters the trigger state.
