Description

Technical Field

[0001] This utility model relates to the field of industrial automation, and in particular to a UVW alignment platform. Background Technology

[0002] As the size of products such as flat panel displays increases, the demand for miniaturized and high-precision products is also intensifying. Major manufacturers have put forward higher requirements for the range, efficiency and accuracy of the moving platform in the vision alignment process. The traditional XYθ platform has a relatively simple structure and cannot rotate the center according to any coordinate point. It is insufficient in terms of positioning accuracy and cannot meet the requirements of high-speed and high-precision vision alignment. Therefore, a UVW alignment platform has emerged.

[0003] The UVW platform consists of a parallel structure of three linear motion axes. Each axis is driven by a ball screw or linear guide via a servo motor. The three axes are distributed at geometric angles of 120 degrees to form a stable support. The displacement of the three axes is synchronously controlled by a servo system. By utilizing the kinematic characteristics of the parallel mechanism, the linear motion is transformed into a planar composite motion, which can realize translation (X, Y) and rotation (θ) centered on any point in the plane. Based on forward and inverse kinematics algorithms, the three-axis displacement and planar coordinate mapping are solved, enabling sub-micron level positioning and angle adjustment in semiconductor, display panel and other scenarios.

[0004] While current UVW alignment platforms drive industry development in fields such as semiconductors and display panels through high-precision angle adjustments, they suffer from insufficient material adaptability. Existing platforms mostly employ fixed clamping, making adjustments difficult when faced with materials of different specifications. For example, semiconductor wafers and flexible OLED panels have significant size differences, and traditional structures require manual replacement of the stage. This not only affects the efficiency of production line changeovers but also increases the cost of multi-variety, small-batch production. Therefore, a UVW alignment platform is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a UVW alignment platform, which aims to improve the problem of insufficient material adaptability and difficulty in adjustment when facing materials of different specifications in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A UVW alignment platform includes an operating platform. A base plate is fixedly connected to the top of the operating platform. Four support blocks are fixedly connected to the top of the base plate. A top plate is slidably connected to the top of the four support blocks. A base is fixedly connected to the top of the top plate. A stud is threadedly connected to the inner wall of the base. A rotating disk is fixedly connected to one side of the stud. A clamping block is rotatably connected to the other side of the stud. Slider blocks are fixedly connected to both sides of the clamping block. Two limiting grooves are formed in the inner wall of the base. A buffer assembly is fixedly connected to the bottom of the top plate.

[0008] As a further description of the above technical solution:

[0009] The buffer assembly includes four fixed posts, the tops of which are fixedly connected to the bottom of the top plate. The inner walls of the fixed posts are slidably connected to sliding posts, and the inner walls of the fixed posts are fixedly connected to limit posts. The outer walls of the limit posts are fitted with springs.

[0010] As a further description of the above technical solution:

[0011] The outer walls of the two sliders are slidably connected to the inner walls of the two limiting grooves, and the cross-sectional shape of the rotating disk is hexagonal.

[0012] As a further description of the above technical solution:

[0013] The outer wall of the limiting post is slidably connected to the inner wall of the sliding post, and the bottom of the sliding post is slidably connected to the top of the operating platform.

[0014] As a further description of the above technical solution:

[0015] The top of the spring is fixedly connected to the inner wall of the fixed column, and the bottom of the spring is fixedly connected to the top of the sliding column.

[0016] As a further description of the above technical solution:

[0017] The clamping block has an anti-slip groove on one side, and the base has a square cross-section.

[0018] As a further description of the above technical solution:

[0019] The bottom of the clamping block is slidably connected to the top of the top plate, and the cross-sectional shape of the fixing column is U-shaped;

[0020] As a further description of the above technical solution:

[0021] The anti-slip groove is serrated, and the clamping block has an arc-shaped cross-section.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the rotating disk drives the stud to rotate on the inner wall of the base, which in turn drives the clamping block to adjust its position at the through hole. This makes the space range formed by the clamping block and the base variable, which can adapt to materials of different specifications. This improves the material adaptability and work efficiency of the UVW alignment platform. The anti-slip groove design makes the clamping block hold the material more firmly. The slider and the limiting groove work together to ensure that the position adjustment of the clamping block is stable when it moves, avoiding shaking and jamming. The structure ensures the flexibility and stability of the clamping system and solves the problem of adapting to multiple specifications of materials in traditional platforms.

[0024] 2. In this utility model, thanks to the cooperation of the limiting column and the spring, when the top plate bears a large load, the fixed column compresses the spring to make it elastically deformed, and the resulting elastic force can offset part of the gravity. At the same time, the sliding column moves with the top plate on the top of the operating platform, and the impact on the precision transmission components in the support block is reduced through the buffer mechanism, avoiding wear and damage to the components due to overload under heavy load. This design can continuously protect the accuracy and stability of the transmission system when aligning heavy materials such as semiconductor wafers and display panels, solve the problem of easy wear and tear under heavy load of traditional platforms, and greatly extend the service life of the UVW alignment platform.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1 to 3 This utility model provides an embodiment of a UVW alignment platform, including an operating platform 1. The operating platform 1 serves as the platform for the entire UVW alignment platform to operate, ensuring the platform remains stable during operation. A base plate 2 is fixedly connected to the top of the operating platform 1, forming the bottom of the UVW alignment platform. Four support blocks 3 are fixedly connected to the top of the base plate 2, and a top plate 4 is slidably connected to the top of the four support blocks 3. The top plate 4 serves as the bearing surface of the working platform, used to place materials to be processed or inspected. The support blocks 3 support the top plate 4 and provide sliding tracks for it, ensuring the stability of the top plate. 4. It can move smoothly and achieve precise positioning. The top plate 4 is fixedly connected to the base 5, which is the key structure for material clamping. The inner wall of the base 5 is threaded with a stud 6. The stud 6 converts rotational motion into linear motion by rotation. A rotating disk 7 is fixedly connected to one side of the stud 6. The rotating disk 7 allows the operator to manually rotate the stud 6, providing a convenient operation method and improving work efficiency. A clamping block 8 is rotatably connected to the other side of the stud 6. The clamping block 8 is in direct contact with the material. By moving, it can clamp and release the material, ensuring that the material remains stable during processing or testing.

[0033] Both sides of the clamping block 8 are fixedly connected to sliders 10. The inner wall of the base 5 has two limiting grooves 11. The limiting grooves 11 provide a sliding track for the sliders 10 to prevent the clamping block 8 from shifting during movement and to ensure the stability of the clamping action. The sliders 10 cooperate with the limiting grooves 11 to limit the movement trajectory of the clamping block 8, ensuring that it moves smoothly along a straight line and improving the clamping accuracy. The bottom of the top plate 4 is fixedly connected to a buffer assembly. The buffer assembly is used to reduce the impact force on the top plate 4, protect the precision transmission components inside the support block 3, and extend the service life of the device. The buffer assembly includes four fixed posts 12. The tops of the four fixed posts 12 are fixedly connected to the bottom of the top plate 4. The inner wall of the fixed posts 12 is slidably connected to a sliding post 13. The inner wall of the fixed posts 12 is fixedly connected to a limiting post 14. The outer wall of the limiting post 14 is fitted with a spring 15. The spring 15 absorbs and disperses the impact force on the top plate 4 through elastic deformation, playing a buffering role and protecting the internal components of the UVW alignment platform.

[0034] Reference Figures 2 to 4The outer walls of the two sliders 10 are slidably connected to the inner walls of the two limiting grooves 11. This cooperation ensures that the clamping block 8 remains stable during movement, avoiding shaking and deviation, thereby improving the accuracy and reliability of material clamping. The cross-sectional shape of the rotating disk 7 is hexagonal. The hexagonal design facilitates rotation, increases operating torque, makes rotation more effortless, and improves work efficiency. The outer wall of the limiting column 14 is slidably connected to the inner wall of the sliding column 13. This structure ensures that the sliding column 13 slides smoothly under the guidance of the limiting column 14, preventing the sliding column 13 from tilting or getting stuck in the fixed column 12, ensuring the normal operation of the buffer assembly. The bottom of the sliding column 13 is slidably connected to the top of the operating platform 1, allowing the sliding column 13 to move to other positions on the top of the operating platform 1. The top of the spring 15 is fixedly connected to the inner wall of the fixed column 12, and the bottom of the spring 15 is fixedly connected to the top of the sliding column 13. This connection method allows the spring 15 to effectively absorb and disperse the impact force on the top plate 4, converting energy into elastic potential energy through elastic deformation, thus playing a buffering and protective role.

[0035] One side of the clamping block 8 is provided with an anti-slip groove 9. The anti-slip groove 9 increases the friction between the clamping block 8 and the material, preventing the material from sliding or falling off during clamping, thus improving the stability and reliability of clamping. The base 5 has a U-shaped cross-section, which provides a larger internal space for easy installation of components such as studs 6 and clamping blocks 8. It also enhances the structural strength of the base 5, ensuring that it will not deform during clamping. The bottom of the clamping block 8 is slidably connected to the top of the top plate 4. This design makes the clamping block 8 move more smoothly, reducing frictional resistance with the top plate 4 and improving stability. The fixed column 12 has a U-shaped cross-section, which provides ample sliding space for the sliding column 13 and spring 15, while also enhancing the structural strength of the fixed column 12 to ensure that it will not deform under pressure. The anti-slip groove 9 is serrated, which can more effectively increase friction and provide a stronger anti-slip effect, ensuring that the material remains stable during clamping. The clamping block 8 has an arc-shaped cross-section, which allows the clamping block 8 to better fit the material surface, increase the contact area, and improve the stability and reliability of clamping.

[0036] Working principle: Rotating the rotating disk 7 causes the stud 6 to rotate on the inner wall of the base 5. This allows the stud 6 to adjust the position of the clamping block 8 at the through hole in the inner wall of the base 5. This adjustment allows for flexibility in handling materials of different specifications, significantly improving the material adaptability and operational efficiency of the entire UVW alignment platform. Thanks to the anti-slip groove 9, the clamping block 8 is more stable when clamping materials. Furthermore, the sliding block 10 and the limiting groove 11... The mutual cooperation allows the stud 6 to stably adjust its position when moving the clamping block 8. Thanks to the cooperation between the limiting post 14 and the spring 15, when the top plate 4 bears a large load, the fixing post 12 compresses the spring 15, causing the spring 15 to undergo elastic deformation and generate elastic force. This elastic force can partially offset the gravity generated by the large load. The sliding post 13 moves on the top of the operating platform 1 as the top plate 4 moves, thus effectively protecting the tightly connected transmission components located inside the support block 3. This significantly extends the service life of the entire UVW alignment platform.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
