Description

Technical Field

[0001] This utility model relates to the field of guide rail technology, specifically to a guide rail type two-dimensional linear platform. Background Technology

[0002] Two-dimensional linear platforms are core components of mechanical equipment, used to support, fix, and guide moving devices or equipment. Due to their high acceleration performance, two-dimensional linear platforms are widely used in equipment for electronics manufacturing, laser processing, and other industries.

[0003] Application publication number CN112060031A discloses a novel mechanical guide rail type two-dimensional linear motion platform, including an X-axis motion module and a Y-axis motion module; the Y-axis motion module is disposed on the X-axis motion module and moves along the X-axis direction under the drive of the X-axis motion module; a motion platform is disposed on the Y-axis motion module, and the motion platform moves along the Y-axis direction under the drive of the Y-axis motion module; both the X-axis and Y-axis motion modules include: a guide rail assembly, a base assembly, a drive assembly, and a detection assembly; the guide rail assembly is mounted on the base assembly, the drive assembly is used to provide driving force, and the detection assembly is used to detect displacement and velocity; the guide rail assembly includes... The system comprises a slider, a guide rail, and a tapered bolt. The guide rail is fixed to a base, and the slider is slidably mounted on the guide rail. The guide rail includes: a first surface facing the slider; second and third surfaces adjacent to the first surface, each having a protrusion at a position away from the base for mounting a rolling component in the slider; and a fourth surface opposite to the first surface and facing the base. The guide rail has countersunk holes penetrating the first and fourth surfaces, with the countersunk portion corresponding to the countersunk bolt being tapered. The guide rail is fixed to the base by the tapered bolt.

[0004] However, there is still room for improvement in the aforementioned novel mechanical guide rail type two-dimensional linear motion platform. For example, since the guide rail of the Y-axis motion module is generally directly fixed to the base, and the slider of the Y-axis motion module is slidably mounted on the guide rail, in this structure, after the motion platform is mounted on the slider of the Y-axis motion module, the combined height (thickness) of the guide rail and the slider results in a relatively high height of the motion platform from the base. In other words, the installation height of the motion platform is relatively high, making it difficult to use in some locations with limited space.

[0005] Therefore, improvements to existing technologies are necessary. Utility Model Content

[0006] To address the problems existing in the prior art, the purpose of this utility model is to provide a guide rail type two-dimensional linear platform. By installing two Y-axis sliders on both sides of the motion plate and ensuring that the top surface of the Y-axis sliders is not higher than the top surface of the motion plate, the overall height of the platform can be reduced, allowing it to be installed in locations with relatively narrow spaces.

[0007] To achieve the above objectives, the technical solution of this utility model is as follows:

[0013] Furthermore, the Y-axis drive mechanism also includes a Y-axis mounting base; the Y-axis motor is mounted on the Y-axis mounting base; an outwardly extending extension plate is provided on one side of the Y-axis mounting base; the top surface of the extension plate abuts against the bottom surface of the motion plate and the extension plate is fixed to the motion plate.

[0014] Furthermore, the X-axis motion module includes a base, two X-axis sliders, two X-axis slide rails, and an X-axis drive mechanism; the two X-axis slide rails are respectively disposed on both sides of the top surface of the base; the two X-axis sliders are slidably connected to the two X-axis slide rails along the X-axis; each X-axis slide rail is correspondingly embedded in an X-axis limiting groove on the top surface of one X-axis slider; the two ends of the motion plate are correspondingly connected to the sides of the two X-axis sliders; the X-axis drive mechanism is mounted on the base; one of the X-axis sliders is connected to the output end of the X-axis drive mechanism.

[0015] Furthermore, the X-axis drive mechanism includes an X-axis motor, an X-axis lead screw, and an X-axis slider; the X-axis motor is mounted on the base; the X-axis lead screw is mounted on the output shaft of the X-axis motor; the X-axis slider is movably mounted on the X-axis lead screw and one side is connected to one of the X-axis sliders.

[0016] Furthermore, the Y-axis mounting base and the Y-axis motor are located between the two X-axis slide rails, while the Y-axis lead screw and the Y-axis sliding block are located outside the two Y-axis slide rails.

[0017] The beneficial effects of this utility model are as follows:

[0018] This invention reduces the installation height of the Y-axis slider and Y-axis slide rail by installing two Y-axis sliders on both sides of the motion plate, ensuring that the top surface of the Y-axis sliders is not higher than the top surface of the motion plate, and embedding the Y-axis slide rail in the Y-axis limiting groove of the Y-axis slider.

[0026] The utility model will be further described below with reference to the accompanying drawings and specific embodiments. The following description is merely exemplary and does not limit the scope of protection of the utility model.

[0027] like Figures 1-3 As shown, a guide rail type two-dimensional linear platform includes an X-axis motion module 2, a Y-axis motion module 1 mounted on the X-axis motion module 2, and a motion platform 3 mounted on the Y-axis motion module 1.

[0028] The Y-axis motion module 1 includes a motion plate 11, two Y-axis sliders 12, two Y-axis slide rails 13, and a Y-axis drive mechanism.

[0029] Specifically, the motion plate 11 is movably connected to the output end of the X-axis motion module 2 along the X-axis; two Y-axis sliders 12 are respectively installed on both sides of the motion plate 11, and the top surface of each Y-axis slider 12 is not higher than the top surface of the motion plate 11, that is, the top surface of the Y-axis slider 12 is lower than the top surface of the motion plate 11 or the top surface of the Y-axis slider 12 is flush with the top surface of the motion plate 11; two Y-axis slide rails 13 are respectively movably connected to the two Y-axis sliders 12 along the Y-axis, so the two Y-axis sliders 12 are actually equivalent to the two side wings of the motion plate 11; each Y-axis slide rail 13 is correspondingly embedded in the Y-axis limiting groove 121 on the top surface of a Y-axis slider 12; the Y-axis drive mechanism is installed on the motion plate 11; the two sides of the bottom surface of the motion platform 3 are correspondingly connected to the top surfaces of the two Y-axis slide rails 13, and one side of the motion platform 3 is connected to the output end of the Y-axis drive mechanism.

[0030] In this embodiment, the X-axis motion module 2 can be used to drive the motion platform 3 to move along the X-axis, while the Y-axis drive mechanism can be used to drive the motion platform 3 to move along the Y-axis.

[0031] This invention reduces the installation height of the Y-axis sliders 12 and Y-axis slide rails 13 by installing two Y-axis sliders 12 on the two sides of the motion plate 11, ensuring that the top surface of the Y-axis sliders 12 is not higher than the top surface of the motion plate 11, and embedding the Y-axis slide rail 13 in the Y-axis limiting groove 121 of the Y-axis sliders 12. This reduces the installation height of the motion platform 3, and thus reduces the overall height of the guide rail type two-dimensional linear platform of this invention. In this way, the guide rail type two-dimensional linear platform of this invention can be installed in some spaces with relatively narrow heights, making it highly practical.

[0032] In this embodiment, a connecting side plate 14 is fixed on one side of each Y-axis slider 12; a connecting groove 15 corresponding to the connecting side plate 14 is respectively provided on the top surface of both sides of the motion plate 11; each connecting side plate 14 is fitted into a connecting groove 15 and connected to the motion plate 11. Therefore, by installing the connecting side plate 14 in the connecting groove 15, the motion plate 11 and the Y-axis slider 12 can be conveniently and stably connected.

[0033] Of course, in order to avoid the connecting side plate 14 protruding from the motion plate 11 and affecting the overall height of the guide rail type two-dimensional linear platform, the top surface of each connecting side plate 14 is not higher than the top surface of the motion plate 11.

[0034] To facilitate the assembly and disassembly of the Y-axis slider 12, the connecting side plate 14 and the motion plate 11 are detachably connected by screws.

[0035] In this embodiment, the Y-axis drive mechanism includes a Y-axis motor 16, a Y-axis lead screw 17, and a Y-axis slider 18. The Y-axis motor 16 is mounted on the motion plate 11; the Y-axis lead screw 17 is mounted on the output shaft of the Y-axis motor 16; the Y-axis slider 18 is movably mounted on the Y-axis lead screw 17 and connected to the motion platform 3 on one side. Therefore, with the above configuration, the Y-axis motor 16 can drive the Y-axis slider 18 to move along the Y-axis by rotating the Y-axis lead screw 17, thereby driving the motion platform 3 and the two Y-axis slide rails 13 to move along the Y-axis. Therefore, during the movement of the motion platform 3 along the Y-axis, the Y-axis slider 12 is in a stopped state, while the Y-axis slide rails 13 are in a moving state.

[0036] In this embodiment, the Y-axis drive mechanism further includes a Y-axis mounting base 19; the Y-axis motor 16 is mounted on the Y-axis mounting base 19; an outwardly extending extension plate 191 is provided on one side of the Y-axis mounting base 19; the top surface of the extension plate 191 abuts against the bottom surface of the motion plate 11 and the extension plate 191 is fixed to the motion plate 11. This arrangement allows for convenient installation of the Y-axis motor 16. Furthermore, since the extension plate 191 is connected to the bottom surface of the motion plate 11, this design also reduces the installation height of the Y-axis mounting base 19 and the Y-axis motor 16 to a certain extent.

[0037] In this embodiment, the X-axis motion module 2 includes a base 21, two X-axis sliders 22, two X-axis slide rails 23, and an X-axis drive mechanism.

[0038] Two X-axis slide rails 23 are respectively disposed on both sides of the top surface of the base 21; two X-axis sliders 22 are slidably connected to the two X-axis slide rails 23 along the X-axis; each X-axis slide rail 23 is correspondingly embedded in the X-axis limiting groove (not shown in the figure) on the top surface of one X-axis slider 22; the two ends of the motion plate 11 are correspondingly connected to the sides of the two X-axis sliders 22; the X-axis drive mechanism is mounted on the base 21; one of the X-axis sliders 22 is connected to the output end of the X-axis drive mechanism. With the above arrangement, the X-axis drive mechanism can drive one X-axis slider 22 to move along the X-axis, and during the movement of this X-axis slider 22, it can drive the motion plate 11 to move along the X-axis, and then the motion plate 11 can drive the other X-axis slider 22 to move. In this design, the X-axis slide rails 23 are stationary, while the X-axis sliders 22 can be used to move synchronously with the motion plate 11.

[0039] Specifically, the X-axis drive mechanism includes an X-axis motor 24, an X-axis lead screw 25, and an X-axis slider 26. The X-axis motor 24 is mounted on the base 21. The X-axis lead screw 25 is mounted on the output shaft of the X-axis motor 24. The X-axis slider 26 is movably mounted on the X-axis lead screw 25 and is connected to one of the X-axis sliders 22 on one side. Therefore, with the above arrangement, when the X-axis motor 24 drives the X-axis lead screw 25 to rotate, it simultaneously drives the X-axis slider 26 and one X-axis slider 22 to move along the X-axis, and the X-axis slider 22 then drives the motion plate 11 to move. In addition, the X-axis motor 24 can also be positioned on the base 21 by a mounting bracket (not shown in the figure).

[0040] In this embodiment, the Y-axis mounting base 19 and the Y-axis motor 16 are located between the two X-axis slide rails 23, while the Y-axis lead screw 17 and the Y-axis sliding block 18 are located outside the two Y-axis slide rails 13. Specifically, since the two X-axis slide rails 23 are spaced apart, there is a certain space between them for installing other components. Therefore, by mounting the Y-axis mounting base 19 and the Y-axis motor 16 between the two X-axis slide rails 23, it is beneficial to reduce the installation height of the Y-axis mounting base 19 and the Y-axis motor 16, thereby ensuring that the installation height of the Y-axis mounting base 19 and the Y-axis motor 16 is not too high and affects the overall height of the guide rail type two-dimensional linear platform.

[0041] The following describes the specific working principle of this utility model in order to help you understand it:

[0042] First, after all the components are installed, when the X-axis motor 24 drives an X-axis slider 22 and a motion plate 11 through the X-axis lead screw 25 and the X-axis sliding block 26, it will synchronously drive the Y-axis motion module 1 and the motion platform 3 to move along the X-axis. Then, when the Y-axis motor 16 drives the motion platform 3 to move along the Y-axis through the Y-axis lead screw 17 and the Y-axis motion block 18, it will synchronously drive the Y-axis slide rail 13 to move on the Y-axis slider 12.

[0043] This utility model is not limited to the above-described embodiments. If any modifications or variations to this utility model do not depart from the spirit and scope of this utility model, and if such modifications and variations fall within the scope of the claims and equivalent technologies of this utility model, then this utility model also intends to include such modifications and variations.
