Description

Technical Field

[0001] The utility model relates to the technical field of marble seismic isolation monitoring, in particular to a marble seismic isolation monitoring feedback structure. Background Art

[0002] For high-precision measuring instruments, the parallelism between the platform and the ground and its own stability are crucial factors for the performance of the equipment installed on the platform. Usually, equipment manufacturers need to ask users to hollow out the ground to install a seismic isolation platform. The disadvantage of this is that the modification is large, the cycle is long, and the equipment is inconvenient to move later; therefore, a flexible and simple seismic isolation structure is necessary. In addition, for the manufacture of semiconductor measurement equipment, a simple marble platform alone cannot meet the stability and accuracy requirements of the equipment. Therefore, in order to solve the high stability and high parallelism requirements of the equipment, a marble shock absorption and monitoring feedback automatic adjustment structure is proposed.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1 , 2 The utility model provides a technical solution: a marble seismic isolation monitoring feedback structure, comprising: a support platform 11 is a metal plate with a through hole in the middle; a support assembly is placed at the bottom of the support platform 11; a plurality of seismic isolation airbags 2 are provided, and the function of the seismic isolation airbags is to suspend the entire marble platform 1 through the airbags to play a seismic isolation role, and the seismic isolation airbags 2 are fixedly installed at the four corners of the top of the support platform 11; the marble platform 1 is fixedly installed on the top of the seismic isolation airbag 2; the distance sensor 7 is placed below the marble platform 1, and the distance sensor 7 is placed at the four corners of the bottom of the marble platform 1, which is used to monitor the numerical change of the bottom height of the marble platform 1, and the sensor numerical change is calculated by the controller algorithm and converted into the corresponding air intake volume of the seismic isolation airbag 2.

[0023] It should be noted that the utility model is provided with a controller, and the use of this platform requires external positive pressure gas. When the gas enters the seismic isolation airbag 2 through the pressure regulating valve 3, the four seismic isolation airbags 2 swell and work together to lift the marble platform 1 and the table equipment; at this time, the marble table needs to be horizontally adjusted by observing the bubble position on the spirit level, and the initial air intake of the seismic isolation airbag 2 is controlled by controlling the value of the pressure regulating valve 3; at this time, one of the seismic isolation airbags 2 needs to be selected as the basic height, and the remaining three seismic isolation airbags 2 are adjusted separately until the bubble on the spirit level is stably centered; after the level adjustment of the marble platform 1 is completed, the four distance measuring sensors 7 can be turned on to read the height value of the bottom surface of the marble platform 1 from the sensor. This value can be used as a calibration value to determine the parallel requirements of the marble platform 1. When the motion mechanism above the marble platform 1 undergoes acceleration and deceleration or the center of gravity position of the equipment above changes later, the marble platform 1 will tilt accordingly, which will cause the value of at least one distance sensor 7 to change. The sensor measures environmental parameters, converts them into signals and sends them to the controller. The controller receives and processes the signals and generates corresponding control signals according to the preset control algorithm. The algorithm can calculate the value change of the sensor to the corresponding air intake volume of the seismic isolation airbag 2. The structure has an automatic feedback adjustment function to ensure the parallelism and stability of the platform and improve the detection accuracy and stability of the equipment on the loading platform. At the same time, the structure can monitor horizontal failures and output alarm information when necessary to feedback problems and faults.

[0024] See also Figure 2 The supporting assembly includes a base frame 4, which is fixedly connected to the four corners of the bottom of the supporting platform 11, and a connecting side plate 12 is fixedly connected between two adjacent base frames 4. The bottom of the base frame 4 is threadedly connected to a load-bearing foot cup 5, and the bottom of the base frame 4 is fixedly connected to a caster 6.

[0025] It should be noted that the base frame 4 of the utility model is the main body of the support assembly, which is fixedly connected to the four corners of the bottom of the support platform 11 to provide stability and strength of the overall structure. Two adjacent base frames 4 are fixedly connected by connecting side panels 12, which help increase the firmness and stability of the overall structure. Four load-bearing foot cups 5 are installed at the bottom of the base frame 4, which are fixed under the base frame. The main function of the load-bearing foot cups is to bear the weight of the entire platform and ensure that the platform is stably supported on the ground. The casters 6 are installed near the load-bearing foot cups 5. These casters facilitate the handling and movement of the machine, making the entire structure have a certain degree of mobility.

[0026] See also Figure 1 , 2 A fixed mounting plate 9 is fixedly connected to the top of the seismic isolation airbag 2, a support plate 10 is fixedly connected to the bottom of the fixed mounting plate 9, pressure regulating valves 3 are fixedly connected to the four corners of the top of the support platform 11, the pressure regulating valve 3 is connected to the seismic isolation airbag 2, a sensor bracket 8 is fixedly connected to the top of the support platform 11 and at the position corresponding to the seismic isolation airbag 2, and the ranging sensor 7 is fixedly connected to the sensor bracket 8.

[0027] It should be noted that in the present invention, when the height of a marble at a certain place is lowered, the value of the distance sensor 7 at this nearby place will become shorter accordingly. The software can convert this value change value into the difference in the air intake of the seismic isolation airbag 2 here through an algorithm formula. The seismic isolation airbag 2 slowly swells with the intake of air, which will push the marble platform 1 to slowly rise. At this time, the value of the distance sensor 7 will increase accordingly. At this time, the software will compare the values ​​of the four distance sensors 7 with the initial basic value ratio (A:B:C:D). In theory, the closer to this ratio, the more parallel they are. This process is only a single-segment description of the adjustment process. The actual adjustment should be that the four marble platforms 1 oscillate and converge until the marble platforms 1 are parallel and stable.

[0028] See also Figure 2 Both sides of the top of the support platform 11 are fixedly connected with mounting frames 13.

[0029] It should be noted that the mounting frame 13 of the present invention is fixedly connected to both sides of the top of the support platform 11, and the mounting frame provides a supporting structure for installing and supporting other components, such as sensors, operating components, etc.
