Description

Technical Field

[0001] This utility model relates to the field of 3D printing technology, and in particular to a 3D printer for independent multi-station continuous printing. Background Technology

[0002] Currently, 3D printing farms have high requirements for printer efficiency and ease of operation. For traditional 3D printers, after printing one model, it is necessary to manually remove it before printing the next model. In 3D printing farms, due to the large number of machines, it is difficult for operators to handle the printed models in a timely manner, which leads to machine downtime, wastes the effective working time of the printer, and reduces printing production efficiency.

[0003] Chinese utility model patent CN220464768U discloses a mobile 3D printer. It evolves from the traditional Prusai3 main gantry responsible for printing the Z and Y axes, while the relative movement of the gantry and printing platform handles the X-axis printing. By extending the X-axis movement range of the printing platform and setting up two printing platforms, the gantry can drive the print head to switch between the two platforms, thereby improving work efficiency. However, this existing technology has three drawbacks: First, the relative movement of the two printing platforms and the gantry for switching printing positions actually shares the original X-axis motion mechanism required for printing. However, the two mechanisms differ in control precision and movement speed. Sharing not only affects switching efficiency but also increases the cost of structure, control, and maintenance due to precision requirements. More importantly, moving the printing platform increases the risk of model damage. Second, the inability to lock and limit the position after switching poses a risk of accidental movement, leading to printing failure. Third, because the existing technology uses a coaxial double-threaded screw and nut pair to move both printing platforms together, it increases the difficulty of expanding to use more printing platforms in parallel. Utility Model Content

[0004] In order to overcome the shortcomings of the background technology and solve the existing technical problems, this utility model discloses an independent multi-station continuous printing 3D printer that ensures stable switching and locking, does not interfere with printing, and is conducive to expanding applications.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A 3D printer for independent multi-station continuous printing includes a printing body and a base frame. At least two printing platforms are longitudinally spaced in the middle of the base frame. The printing body is mounted and supported on both sides of the base frame and can move longitudinally along the base frame. A locking and positioning mechanism is provided between the printing body and the base frame to lock the printing body at any of the printing platforms.

[0007] Furthermore, the base frame includes a base frame, and multiple legs are symmetrically arranged on both sides of the lower surface of the base frame. Two support rods are connected between the two end frames of the base frame, and the printing platform fixing frame is supported above the two support rods.

[0008] Furthermore, the locking and positioning mechanism includes several locking elements corresponding to each printing platform and fixed to the base frame, a locking element is installed on the lower part of the printing body, and a driving element that drives the locking element to move and resist the locking elements to limit the locking.

[0009] Furthermore, the locking element is configured as a locking groove, the locking element is configured as a locking tongue plate that is rotatably mounted on the printing body at one end via a fixed rotating shaft, and the driving element is configured to drive the rotating shaft to rotate, so that the other end of the locking tongue plate is correspondingly inserted into the locking groove by a locking motor.

[0010] Furthermore, the locking element is configured as a lock sleeve, the locking element is configured as a locking pin that corresponds to and fits the inner hole of the lock sleeve, and the driving element is configured as a telescopic pole with the locking pin coaxially fixed at the pole end.

[0011] Furthermore, the printing body includes two side frames and a top frame connected between the tops of the two side frames. Two lead screw nut pairs and two slider guide rail pairs are symmetrically installed on both sides of the base frame. The bottom end of the side frame is fixedly connected to the outer wall of the nut of the corresponding lead screw nut pair and the slider of the corresponding slider guide rail pair, respectively. The lead screw of the lead screw nut pair is connected to a drive motor.

[0012] Furthermore, the printing body also includes a printing frame, which is mounted on two side frames via a Z-axis moving mechanism. An X-axis moving mechanism and a Y-axis moving mechanism are also mounted on the printing frame.

[0013] By adopting the technical solution described above, this utility model has the following beneficial effects:

[0014] This utility model discloses an independent multi-station continuous printing 3D printer that switches printing platforms by actively moving the printing body, thereby reducing printer downtime and improving printing and mold-taking efficiency. Compared with the prior art, this utility model separates and controls printing and switching, ensuring that they do not interfere with each other. This improves switching efficiency and ensures printing quality. After switching, the printing body and printing platform can be locked together by a locking and positioning mechanism to prevent accidental movement, thus improving printing stability and safety. Furthermore, since the printing platform does not need to move, multiple printing platforms can be extended and set up side by side according to printing needs, which is beneficial for expanding applications and market promotion.

[0018] The technical solution of this utility model will now be described with reference to the accompanying drawings of the embodiments of this utility model. In the description, it should be understood that the terms "upper," "lower," "front," "rear," "left," and "right," etc., indicating directions or positional relationships, are only used to correspond to the accompanying drawings of this utility model for ease of description, and do not indicate or imply that the device or element referred to must have a specific orientation.

[0019] Combined with appendix Figure 1-2 The independent multi-station continuous printing 3D printer includes a printing body and a base frame. At least two printing platforms 2 are longitudinally spaced in the middle of the base frame. Setting two printing platforms 2 facilitates switching between printing bodies and avoids printing stoppages caused by mold removal. The specific number of printing platforms 2 can be set according to the mold removal and cleaning time and the printing time. If the printing time is short and the mold removal and cleaning is cumbersome, and there is not enough time to switch between the two printing platforms 2, more printing platforms 2 can be set. As needed, the base frame includes a bottom frame 1. Multiple legs are symmetrically arranged on both sides of the lower surface of the bottom frame 1 to ensure stable support. Two support longitudinal rods are connected between the two ends of the bottom frame 1. The printing platform 2 is fixed above the two support longitudinal rods. To prevent the support longitudinal rods from being too long and affecting the structural strength, support crossbars can also be set between two adjacent printing platforms 2 to provide segmented support for the support longitudinal rods.

[0020] The main printing unit is supported on both sides of the base frame and can move longitudinally along the base frame. The printing platform 2 is switched by actively moving the main printing unit, thereby reducing printer downtime. Depending on the needs, the main printing unit includes two side frames 3 and a top frame 4 connected between the tops of the two side frames 3. Two lead screw nut pairs and two slider guide rail pairs are symmetrically installed on both sides of the base frame. The bottom ends of the side frames 3 are fixedly connected to the outer walls of the nuts 6 of the corresponding lead screw nut pairs and the sliders 5 of the corresponding slider guide rail pairs, respectively. The lead screw 7 of the lead screw nut pairs and the guide rails 9 of the slider guide rail pairs are installed side-by-side on the corresponding sides of the bottom frame 1. The lead screw 7 of the lead screw nut pairs is driven by a drive motor 8, which controls the two... Each drive motor 8 synchronously drives the corresponding lead screw 7 to rotate, thereby causing the nut 6 to move the printing body along the guide rail 9, realizing the relative switching of the printing platform; in addition, the printing body also includes a printing frame, which is parallel to the printing platform 2. The printing frame is mounted on two side frames 3 through a Z-axis moving mechanism. The printing frame is equipped with an X-axis moving mechanism and a Y-axis moving mechanism. Generally, the Y-axis moving mechanism drives the X-axis moving mechanism to move along the Y-axis, and the X-axis moving mechanism drives the nozzle to move along the X-axis. That is, the entire 3D printing operation mechanism is on the printing body and moves with the printing body. It does not interfere with the platform switching movement, resulting in higher printing accuracy and faster switching efficiency.

[0021] A locking and positioning mechanism is provided between the printing body and the base frame to lock the printing body at any printing platform 2. This mechanism typically includes several locking elements 10 corresponding to each printing platform 2 and fixed to the base frame. A locking element 11 is installed at the bottom of the printing body, along with a driving element 12 that moves the locking element 11 to engage with the locking element 10 for locking. When the printing body is in position, the driving element 12 drives the locking element 11 to move towards the locking element 10, creating a locking engagement in the direction of the printing body's movement. This achieves the locking function between the printing body and the base frame, preventing accidental movement. Unlocking is achieved by reversing the movement of the locking element 11. Each Two locking elements 10 can be symmetrically arranged on both sides of the printing platform 2. Corresponding locking elements 11 and driving elements 12 are also set to two, so as to ensure that both sides of the printing body can be stably locked to both sides of the base frame when locked. Specifically, the locking element 10 can be set as a locking groove, the locking element 11 can be set as a locking tongue plate that is rotatably installed on the printing body through a fixed rotating shaft at one end, and the driving element 12 can be set as a locking motor that can drive the rotating shaft to rotate, so that the other end of the locking tongue plate is inserted into the locking groove; or the locking element 10 can be set as a locking sleeve, the locking element 11 can be set as a locking pin that is adapted to the inner hole of the locking sleeve, and the driving element 12 can be set as a telescopic rod that fixes the locking pin coaxially at the rod end.

[0022] The 3D printer with independent multi-station continuous printing described in this utility model can unlock and move longitudinally along the base frame after printing a model on the first printing platform, automatically switch to the second printing platform and lock it, and then print the second model. During the printing of the second model, the model on the first printing platform can be operated independently to retrieve the model. After printing the second model, it can automatically unlock and switch back to the first platform to print the third model, achieving seamless printing and improving printing production efficiency.
