[0021] The utility model provides the following description of reference drawings to help comprehensively understand various embodiments of the utility model as defined by the claims and its equivalents. The description includes various specific details to help understanding, but these details should be regarded as just exemplary. Therefore, those skilled in the art will realize that various changes and modifications can be made to various embodiments described herein without departing from the scope and spirit of the utility model.
[0022] In the description of the utility model, the orientation description, such as the orientation or positional relation of up, down, front, back, left, right and the like, is based on the orientation or positional relation shown in the drawings, and is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model.
[0023] It should be understood that when an element (e.g., a first element) is "connected" with another element (e.g., a second element), the element can be directly connected with the other element, or there can be intervening elements (e.g., a third element) between the element and the other element.
[0024] The embodiment of the utility model provides a kind of high stability 3D printer Z axis module, as shown in Figures 1-4 It is shown that including Z axis guide rail 101, slider structure 102 is slidably connected on Z axis guide rail 101 and the driving structure 103 for driving slider structure 102 moves up and down, and the anti-offset structure 200 is arranged between slider structure 102 and driving structure 103, and the anti-offset structure 200 is used to reduce the lateral offset jitter of slider structure 102 when moving up and down.
[0025] Specifically, Z axis guide rail 101 has good straightness and parallelism, closely adheres with slider structure 102, to ensure that the slider can smoothly slide along the predetermined track;Slider structure 102 can be connected with external connector, or can be directly integrated with driving structure 103, slider structure 102 is connected with components such as print head, and can be adapted and installed according to the interface of different print heads.Driving structure 103 can be motor and screw structure, which converts rotary motion into up-down linear motion of slider structure 102, with high stability;It can also be a driving structure such as air pressure rod.Because there is still a certain gap between slider structure 102 and driving structure 103 after connection, anti-offset structure 200 is arranged between slider structure 102 and driving structure 103, which effectively eliminates the left-right offset jitter generated when driving structure 103 drives slider structure 102 to move up and down, improves the stability and precision of printing process, reduces the generation of product corrugation, and the anti-offset structure 200 of the Z axis module improves the stability and precision of 3D printing process.
[0026] In some embodiments, as shown in Figures 2-3 Driving structure 103 includes driving seat 106 connected with slider structure 102 and driving part 107 for driving driving seat 106, and anti-offset structure 200 includes elastic structure 201 abutting with the bottom end of driving seat 106 and abutting with the top end of slider structure 102.
[0027] The driving seat 106 is connected with the sliding block structure 102 by a fixing mode such as a bolt, the driving member 107 drives the driving seat 106 to drive the sliding block structure 102 to move up and down under the guidance of the Z-axis guide rail 101, and meanwhile the concentricity difference between the driving seat 106 and the supporting arm 105 can be eliminated through the elastic structure 201. When the sliding block structure 102 is subjected to external forces such as vibration or transverse force of a printing head during the up-and-down movement and generates a transverse deviation, the elastic structure 201 such as a spring or elastic sheet will be elastically deformed to generate a correction force to pull the sliding block structure 102 back to the predetermined up-and-down movement track, so as to conveniently correct the transverse deviation of the sliding block structure 102 during the movement in real time, ensure the up-and-down movement of the sliding block structure 102 along the Z-axis guide rail 101, and thus improve the printing precision and reduce the product wave problem caused by the deviation.
[0028] Further, as shown in Figure 3 , the sliding block structure 102 is provided with a first groove 202 matched with the elastic structure 201 at the bottom.
[0029] In practice, the bottom end of the elastic structure 201 abuts against the top surface of the driving seat 106, the top end abuts against the bottom surface of the sliding block structure 102, the elastic structure 201 is fixed and compressed in the first groove 202 between the driving seat 106 and the sliding block structure 102, and the displacement of the elastic structure 201 during the work is ensured.

The bottom of the bracket 105 is connected with the driving seat 106 by means of screwing, welding or other connection methods. Compared with the integral sliding block structure 102, the structure of the externally connected bracket 105 can reduce the required assembly precision and reduce the cost. The elastic structure 201 is in abutment between the bottom of the bracket 105 and the driving seat 106, which facilitates the elimination of the offset with the up and down movement of the driving seat 106.

[0037] Specifically, the driving seat 106 is inserted into the bottom of the bracket 105 and connected with the bracket 105 through the boss 108, so that the center of gravity is moved upward, improving the stability of driving. The arrangement of the boss 108 also facilitates assembly and fixation with the elastic structure 201.
