Description

Technical Field

[0001] The utility model relates to the technical field of processing equipment, in particular to a gantry dual-drive platform. Background Art

[0002] With the increasing automation in modern industry, the demand for high-precision, high-speed processing equipment is growing. As an important processing equipment, gantry dual-drive platforms are widely used in precision machining fields such as semiconductor manufacturing, laser cutting, and precision assembly. Traditional gantry-style machining platforms typically use mechanical transmission to position moving parts. While this method can meet basic machining requirements, it has certain limitations in terms of machining accuracy, operating speed, and stability.

[0003] In recent years, with the advancement of linear motor technology and its expanding application, an increasing number of gantry platforms have begun adopting linear motors as their drive source. Linear motors can directly convert electrical energy into linear motion without the need for an intermediate transmission link, significantly improving the system's response speed and positioning accuracy. However, existing linear motor-driven gantry platforms still face challenges, such as how to further improve system stability and reliability while maintaining high precision, and how to achieve a more compact and efficient layout within limited space. Utility Model Content

[0004] The present invention aims to at least solve the technical problems existing in the prior art. To this end, the present invention proposes a gantry dual-drive platform that achieves higher machining accuracy and stability while optimizing the structural design to adapt to a wider range of industrial application requirements.

[0028] The present invention avoids the cumulative errors caused by traditional gear rack or screw transmission by utilizing direct drive of linear motors, thereby greatly improving the positioning accuracy of the system. The sliding connection between the first linear motor stator 3 and the first linear motor mover 8 ensures the smooth movement of the beam 9 in the X-axis direction, while the second linear motor stator 10 and the second linear motor mover 14 ensure precise control in the Y-axis direction. Since linear motors have the characteristics of fast response speed and strong acceleration and deceleration capabilities, they can still maintain good dynamic performance when the direction of movement is frequently changed, which helps to improve processing efficiency and shorten the production cycle. At the same time, the present invention adopts a compact structural layout. The side plates 2 on both sides of the base 1 not only provide support, but also integrate the stator part of the first linear motor. The design of the first connecting plate 6 and the second connecting plate 7 makes the entire system more stable and reduces errors caused by structural deformation. The design of the connecting seat 13 facilitates the installation of various processing tools or measuring devices, enhancing the functionality and applicability of the equipment.

[0029] It is understandable that the connection base 13 is provided with a plurality of connection holes 15 for connecting external devices.

At the same time, the structure is compact, effectively reducing installation space.

[0031] In the gantry dual-drive platform described in this embodiment, a second grating scale 18 is provided at the bottom of the crossbeam 9, and a second reading head 19 is provided at the inner bottom of the connecting seat 13. The second reading head 19 is provided corresponding to the second grating scale 18. Specifically, the cooperation between the second grating scale 18 and the second reading head 19 is also used for position detection, ensuring the motion accuracy in the Y-axis direction, which is particularly important for applications requiring high-precision processing or measurement.

The first sensing sheet 22 is disposed correspondingly to the first photoelectric switch 20. Specifically, the arrangement of the first photoelectric switch 20 and the first sensing sheet 22 can be used to detect position and implement a limit protection function, preventing the connecting base 13 from exceeding a predetermined travel range, protecting the equipment from damage, and also improving operational safety.

[0033] In the gantry dual-drive platform described in this embodiment, a plurality of second photoelectric switches 23 are provided on the inner side of the side panels 2, and a second sensing plate 24 is provided on the bottom of the second connecting plate 7. The second sensing plate 24 is provided corresponding to the second photoelectric switches 23.

Each second rail 11 is provided with a second slider 12, which is disposed at the upper and lower ends of the inner side of the connecting seat 13. Specifically, the provision of two second rails 11 and the configuration of a second slider 12 on each of the upper and lower sides of the second linear motor stator 10 improve the motion stability and parallelism of the crossbeam 9 in the Y-axis direction, thereby enhancing the overall rigidity of the system.

[0035] In the gantry dual-drive platform described in this embodiment, first end plates 25 are provided at both the front and rear ends of the side panels 2. First anti-collision blocks 26 are provided on the inner sides of the first end plates 25. The two first anti-collision blocks 26 are located at the front and rear ends of the first slide rail 4, respectively. Specifically, the first end plates 25 and the first anti-collision blocks 26 therein act as buffers when the first slide 5 reaches its extreme position, reducing the impact force caused by a collision, thereby extending the life of the equipment and reducing maintenance costs.

[0036] In the gantry dual-drive platform described in this embodiment, second end plates 27 are provided at both the left and right ends of the crossbeam 9. Second anti-collision blocks 28 are provided on the inner sides of the second end plates 27.
