Technical Field

[0001] This utility model relates to the field of 3D printing equipment technology, specifically a multi-nozzle collaborative calibration and positioning device. Background Technology

[0002] In the field of 3D printing, to improve printing quality and enrich the diversity of printed products, multi-nozzle 3D printers, as printing devices equipped with multiple nozzle assemblies, not only enable multi-material and multi-color printing of the same product, thus improving printing efficiency, but also enhance the device's customization capabilities. The nozzles of 3D printers require high-precision positioning and calibration to ensure that the 3D printing materials ejected from each nozzle group fit together during multi-nozzle operation, thereby guaranteeing a good bonding effect between materials of different colors and textures. Therefore, we propose a multi-nozzle collaborative calibration and positioning device.

[0003] The existing technology still has the following drawbacks in its use: Existing multi-nozzle collaborative calibration and positioning devices use software positioning and calibration. They initialize and zero the calibration position, and then use algorithms to calibrate deviations that occur during the printing process. This results in the nozzles being recalibrated after problems occur, which can lead to defects in the actual printing process and affect the final printing effect and quality of the 3D printing equipment.

[0004] In view of this, we propose a multi-nozzle collaborative calibration and positioning device to solve the existing problems. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention employs several calibration rings and fastening rings that contact the nozzle assembly. After contact with the calibration rings and fastening rings, the nozzle assembly, driven by the three-dimensional drive mechanism, calibrates along the X, Y, and Z axes respectively.

[0016] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] like Figures 1-5 As shown, the present invention proposes a multi-nozzle collaborative calibration and positioning device, including a mounting frame 2 and a calibration ring 6. Several support frames 3 are bolted to the bottom of the mounting frame 2. The mounting frame 2 can provide mounting positions for surrounding components. The support frames 3 can be connected to 3D printing equipment to support and fix the mounting frame 2, so as to ensure the calibration effect of the mounting frame 2 and its surrounding components for multiple sets of nozzle components. A connector rod 5 is installed through the interior of the mounting frame 2. One end of the connector rod 5 passes through the mounting frame 2, and the other end of the connector rod 5 is connected to the inner wall of the mounting frame 2. The connector rod 5 can provide a position for the calibration ring 6 to be installed, so that several sets of calibration rings 6 can be stably installed on the inner side of the mounting frame 2 through the connector rod 5 and the reinforcing plate 4. Several calibration rings 6 are evenly spaced on the inner side of the mounting bracket 2. Each calibration ring 6 has two insertion holes inside, which are connected to the insertion rod 5. T-shaped slots are provided on both sides of the top of the calibration ring 6. The calibration ring 6 can contact multiple sets of nozzle assemblies, so that the nozzle assemblies can be calibrated on the X, Y and Z axes. This ensures that multiple sets of nozzle assemblies are in the same position on the X, Y and Z axes, thereby ensuring that multiple sets of nozzles can have good printing effect in the actual 3D printing process. The calibration ring 6 is fitted with reinforcing plates 4 on both sides. The reinforcing plates 4 can support and fix the two adjacent sets of calibration rings 6, thereby ensuring the installation stability between the calibration rings 6 and preventing irregular shaking during the calibration process from affecting the calibration effect of multiple nozzle assemblies.

[0018] Furthermore, the mounting bracket 2 is a U-shaped groove, and the bottom of the mounting bracket 2 is designed with a slope. The height of the back part of the mounting bracket 2 is greater than the height of the front part. The side of the mounting bracket 2 is a trapezoidal structure. The mounting bracket 2 can provide installation positions for surrounding components. The trapezoidal structure of the side can ensure the structural stability of the mounting bracket 2, reduce the shaking of the mounting bracket 2 during use, and thus improve the calibration effect of the device on multi-nozzle components.

[0019] Furthermore, a fastening ring 1 is fixedly installed on the inner side of the calibration ring 6. The fastening ring 1 has beveled surfaces on both sides of its front side. The fastening ring 1 is made of an elastic material, such as silicone or rubber. The inner diameter of the fastening ring 1 is designed to be 3 to 5 mm larger than the diameter of the nozzle assembly, so that the nozzle assembly can be locked inside the fastening ring 1. During calibration, the nozzle assembly has a certain amount of movement play, which facilitates the calibration of the nozzle assembly along the X, Y, and Z axes.

[0020] Furthermore, the calibration ring 6 has a U-shaped structure, and the fastening ring 1 inside the calibration ring 6 also has a U-shaped structure. The fastening ring 1 fits into the inner wall of the calibration ring 6, and the calibration ring 6 can cooperate with the fastening ring 1 to improve the calibration effect of the device on the nozzle assembly.

[0021] Furthermore, triangular reinforcing ribs are provided on both the front and back sides of the support frame 3, and two bolts are fixedly installed on both sides of the bottom of the support frame 3. The triangular reinforcing ribs on both sides of the support frame 3 can improve the overall support stability of the support frame 3, thereby preventing the support frame 3 from shaking and affecting the installation stability of the mounting frame 2, and improving the calibration accuracy of the device for the entire nozzle assembly.

[0022] Furthermore, the reinforcing plate 4 is an I-shaped plate, and both ends of the reinforcing plate 4 are respectively engaged and connected to the T-shaped slots on the top of the two adjacent sets of calibration rings 6. The reinforcing plate 4 can support and fix the two adjacent sets of calibration rings 6 on the one hand, and make the device convenient to install and disassemble on the other hand.

[0023] Working principle: After the support frame 3 is fixedly installed in the designated position on the 3D printer, the mounting frame 2 is fixedly installed on the top of the support frame 3. Several calibration rings 6 are installed on the inner side of the mounting frame 2 through the plug rod 5, and the two adjacent calibration rings 6 are reinforced by the reinforcing plate 4 to complete the overall installation of the device. During calibration and positioning, the three-axis moving mechanism in the 3D printer drives several nozzle assemblies to move towards the calibration rings 6, so that the nozzle assemblies are all in contact with the fastening rings 1 on the inner side of the calibration rings 6. At the same time, the nozzle assemblies are moved along the X-axis, Y-axis and Z-axis respectively, so that all nozzle assemblies are in contact with the calibration rings 6 and the fastening rings 1, thereby adjusting all nozzle assemblies to the same position to complete the positioning and calibration.

[0024] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
