Description

Technical Field

[0001] This utility model relates to the field of industrial automation technology, and in particular to a buffer rotary table. Background Technology

[0002] In modern industrial manufacturing and precision equipment, buffer rotary stages, as core components for supporting and transferring workpieces, are widely used in semiconductor processing, optical instruments, automated production lines, and other scenarios. This device needs to achieve high-precision rotational positioning while effectively buffering external impacts to ensure the stability and integrity of the workpiece during processing and transfer. With the continuous improvement of product precision requirements, higher standards are being placed on the performance of buffer rotary stages.

[0003] Currently, traditional rotating platforms with buffers mostly employ a single structural design, such as using simple rubber pads for impact cushioning or relying on mechanical clips to connect and fix the platform to the equipment. Their working principle is primarily based on rigid contact and static adsorption; that is, the product is fixed to the surface of the aluminum platform through negative pressure adsorption, and rotation is achieved using gear transmission or belt drive. This design relies on a negative pressure system to maintain contact between the product and the platform, restricts relative displacement through rigid friction, and relies on fixed limiting structures for positioning during rotation.

[0004] However, existing technologies have significant drawbacks: because the product is in direct contact with the aluminum stage and is fixed solely by negative pressure adsorption, it is difficult to completely eliminate minute misalignments between the product and the stage when the stage rotates, accelerates, decelerates, or is subjected to minor external impacts. This misalignment can cause relative sliding between the product surface and the stage, resulting in soft scratches that affect the product's surface quality and processing accuracy. Especially in production scenarios where surface integrity is extremely critical, such as those involving semiconductor chips and precision optical components, even minor scratches can directly lead to product scrap, increasing production costs and reducing production efficiency. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a buffered rotating platform, which aims to improve the problem that when the product is in direct contact with the aluminum platform of a traditional platform, the product and the platform are adsorbed by negative pressure, resulting in slight displacement and soft scratches during rotation.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a buffer rotating platform, including a platform body, wherein an installation hole is provided on the outer wall of the platform body, an installation component is provided on the inner wall of the installation hole, and a buffer protection component is provided on the inner wall;

[0007] The buffer protection assembly includes a damper, which is fixedly connected to the inner wall of the platform body. A spring is sleeved on the outer wall of the damper piston rod. A sliding table is fixedly connected to one end of the damper piston rod. A buffer pad is fixedly connected to the outer wall of the sliding table. A friction hemisphere is provided on the outer wall of the buffer pad. Negative pressure adsorption holes are provided on the inner walls of the platform body, the buffer pad, and the sliding table.

[0008] Furthermore, the installation includes an installation cylinder, the outer wall of which is fixedly connected to the inside of the installation hole. A push-button switch is slidably connected to the inner wall of the installation cylinder. A moving platform is fixedly connected to the lower surface of the push-button switch. A U-shaped groove is formed on the outer wall of the installation cylinder. A sliding column is fixedly connected to the outer wall of the moving platform. A connecting rod is fixedly connected to the lower surface of the moving platform. A pressing block is fixedly connected to one end of the connecting rod. Two pressure blocks are slidably connected to the outer wall of the pressing block. A spring is fixedly connected between the two pressure blocks. A fixing spike is fixedly connected to the outer wall of each of the two pressure blocks.

[0009] Furthermore, the outer wall of the fixing spike is slidably connected to the inner wall of the mounting cylinder, and the fixing spike is used to assemble the platform body with the equipment.

[0010] Furthermore, the outer wall of the sliding column is slidably connected to the inside of the U-shaped sliding groove, which consists of two vertical sliding grooves and one horizontal sliding groove.

[0011] Furthermore, the outer wall of the extrusion block is disposed on the inner wall of the mounting cylinder, and the extrusion block is used to extrude two pressure blocks to move relative to each other.

[0012] Furthermore, the outer wall of the sliding stage is slidably connected to the inner wall of the platform body, and the sliding stage is used to drive the buffer pad to move.

[0013] Furthermore, the outer wall of the sliding stage is slidably connected to the inner wall of the platform body, and the sliding stage is used to drive the buffer pad to move.

[0014] Furthermore, the outer wall of the moving platform is slidably connected to the inner wall of the mounting cylinder, and the moving platform is used to press the connecting rod.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, when the platform is impacted, the hemispherical structure on the surface of the buffer pad increases the resistance and reduces the impact. The impact force is transmitted through the buffer pad, which pushes the sliding table to compress the damper and the spring, realizing multi-stage buffering and shock absorption. This solves the problem that in traditional platforms, the product is in direct contact with the aluminum platform, and the product and platform are adsorbed by negative pressure. During rotation, a slight deviation will occur, resulting in soft scratches. This invention achieves the purpose of ensuring stable contact between the product and the platform, eliminating rotational deviation, avoiding soft scratches, and improving the surface quality and processing accuracy of the product.

[0017] 2. In this utility model, after inserting the mounting cylinder into the equipment mounting hole, pressing the switch causes the fixing spike to extend and embed into the equipment. After rotating the switch, releasing it completes the locking, realizing the rapid and stable installation of the platform. This achieves the goal of rapid and accurate installation and secure locking of the platform, ensuring that the platform installation position is accurate, enhancing the adsorption stability between the product and the platform, and effectively avoiding rotational displacement and soft scratches caused by installation problems.

[0026] 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.

[0027] Reference Figures 1-3An embodiment of this utility model is provided: a buffer rotating platform, including a platform body 1, an installation hole 2 is provided on the outer wall of the platform body 1, an installation component is provided on the inner wall of the installation hole 2, and a buffer protection component is provided on the inner wall.

[0028] The buffer protection assembly includes a damper 8, which is fixedly connected to the inner wall of the platform body 1. A spring 9 is sleeved on the outer wall of the piston rod of the damper 8. A sliding table 7 is fixedly connected to one end of the piston rod of the damper 8. A buffer pad 3 is fixedly connected to the outer wall of the sliding table 7, directly contacting the external impact. Through its own material and surface structure, it initially reduces the impact force and transmits the impact force to the sliding table 7, playing a buffering and transition role. A friction hemisphere 4 is provided on the outer wall of the buffer pad 3, which increases the contact friction with the impacting object, reduces the force of the external impact on the platform, and improves the buffering effect. Negative pressure adsorption holes 5 are opened on the inner walls of the platform body 1, the buffer pad 3, and the sliding table 7.

[0029] Specifically, when the platform body 1 is subjected to external impact, the friction hemisphere 4 on the surface of the buffer pad 3 first contacts the impacting object, and initially reduces the impact force by increasing the friction. Subsequently, the impact force is transmitted to the sliding table 7 through the buffer pad 3. The sliding table 7 slides inside the platform body 1, compressing the damper 8 and spring 9. The damper 8 uses hydraulic pressure to generate viscous resistance, and the spring 9 provides elastic reaction force to achieve multi-stage buffering.

[0030] Reference Figures 1-6The installation includes an installation cylinder 6, whose outer wall is fixedly connected to the inside of the installation hole 2. A push-button switch 10 is slidably connected to the inner wall of the installation cylinder 6. A moving platform 13 is fixedly connected to the lower surface of the push-button switch 10. A U-shaped groove 11 is provided on the outer wall of the installation cylinder 6. A sliding column 12 is fixedly connected to the outer wall of the moving platform 13. A connecting rod 14 is fixedly connected to the lower surface of the moving platform 13. A pressing block 16 is fixedly connected to one end of the connecting rod 14. Two pressure blocks 17 are slidably connected to the outer wall of the pressing block 16. After being pressed by the pressing block 16, the pressure blocks 17 slide to both sides, causing the fixing spikes 15 to extend or retract. A spring 18 is fixedly connected between the two pressure blocks 17. Fixing spikes 15 are fixedly connected to the outer walls of both pressure blocks 17. Under the action of the pressure blocks 17, the spring 18 extends or retracts. The mounting cylinder 6 is embedded inside the equipment to achieve a firm connection between the platform body 1 and the equipment, preventing the platform from loosening during use. The outer wall of the fixing spike 15 is slidably connected to the inner wall of the mounting cylinder 6. The fixing spike 15 is used to assemble the platform body 1 and the equipment. The outer wall of the sliding column 12 is slidably connected to the inside of the U-shaped sliding groove 11. The U-shaped sliding groove 11 consists of two vertical sliding grooves and one horizontal sliding groove. The outer wall of the extrusion block 16 is set on the inner wall of the mounting cylinder 6. The extrusion block 16 is used to extrude two pressure blocks 17 to move relative to each other. The outer wall of the sliding table 7 is slidably connected to the inner wall of the platform body 1. The sliding table 7 is used to drive the buffer pad 3 to move. The buffer pad 3 is made of silicone rubber. The outer wall of the moving table 13 is slidably connected to the inner wall of the mounting cylinder 6. The moving table 13 is used to extrude the connecting rod 14.

[0031] Specifically, after inserting the mounting cylinder 6 into the corresponding mounting hole 2 of the equipment, press the push switch 10. The moving platform 13 moves down, causing the sliding column 12 to slide in the vertical slide groove on the right side of the U-shaped slide groove 11. The moving platform 13 pushes the pressing block 16 to press the pressure block 17 through the connecting rod 14. The pressure block 17 overcomes the tension of the second spring 18 and slides to both sides, causing the fixing spike 15 to extend and embed into the equipment. Rotate the push switch 10 45 degrees, and the sliding column 12 enters the left vertical slide groove through the horizontal slide groove. Release the push switch 10, and the second spring 18 retracts and locks the connecting rod 14, completing the assembly of the platform body 1 and the equipment.

[0032] Working principle: When the buffer rotating platform is used, the platform body 1 is subjected to external impact. The buffer pad 3 first contacts and increases the friction through the friction hemisphere 4 to reduce the impact force. The impact force is transmitted to the sliding table 7 through the buffer pad 3. The sliding table 7 slides along the inside of the platform body 1 and compresses the damper 8 and spring 9. The damper 8 generates viscous resistance through hydraulic pressure, and the spring 9 provides elastic reaction force to achieve multi-stage buffering and reduce the impact on the platform.

[0033] Furthermore, after inserting the mounting cylinder 6 into the corresponding mounting hole 2 of the equipment, press the push switch 10. The moving platform 13 moves down along the inside of the mounting cylinder 6, causing the sliding column 12 to slide in the right vertical slide groove of the U-shaped slide groove 11. At this time, the moving platform 13 pushes the pressing block 16 to press the two pressure blocks 17 through the connecting rod 14. The pressure blocks 17 overcome the tension of the second spring 18 and slide to both sides, causing the fixing spike 15 to extend out of the mounting cylinder 6 and embed into the inside of the equipment. Then, by rotating the push switch 10, the sliding column 12 enters the left vertical slide groove when passing through the horizontal slide groove at a 45-degree angle. At this time, when the push switch 10 is released, the connecting rod 14 is locked when the second spring 18 retracts, realizing the rapid assembly of the platform body 1 and the equipment.

[0034] 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.
