Description

Vibration simulation device and its control method {VIBRATION SIMULATOR AND CONTROL METHOD THEREOF}

The present invention relates to a vibration simulating device and a control method thereof, and more particularly, to a vibration simulating device and a control method for preventing failure by continuously monitoring an operating facility by collecting, analyzing, and defining vibration data.

The biggest boundary factor for factory operation is downtime (time that cannot be operated due to machine or system failure), and if the factory stops even for a moment, it leads to huge losses.

A representative example is a semiconductor factory. If a semiconductor factory stops even for a moment due to a power outage or equipment failure, a huge amount of damage occurs in the billions to trillions depending on the scale. This is because if the factory stops, all wafers produced must be discarded.

Republic of Korea Patent Registration No. 10-0549964 discloses an exciter for simulating a vibration environment.

The prior art is an exciter capable of simulating a vibration environment, and can simulate the actual environment of an operating facility.

However, in the prior art, stability can only be confirmed when the operating facility is operated in a real environment by simulating the vibration environment of a specific state of the operating facility, and failure prevention for the operating facility is impossible.

In addition, Korean Patent Publication No. 10-2022-0011884 discloses a vision inspection-based predictive maintenance device.

The prior art is a technology for predictive maintenance or safety control for predicting possible accidents in advance by comparing pictures taken at different times based on vision inspection.

However, in the prior art, although predictive maintenance is performed using image information, there is a problem in that the failure prevention effect is not effective when the location of the operating equipment is not changed through the image information. For example, when a motor operating inside an operating facility fails, there is a problem that cannot be predicted.

Recently, with the advancement of smart factories by data integration, related facility management technologies are also rapidly developing. Accordingly, it is possible to prevent the occurrence of failures of operating facilities in advance, and a more effective failure prevention technology is required.

Referring to FIG. 4 together with FIGS. 1 to 3, the operation relationship and control method of the vibration simulation device according to an embodiment of the present invention will be described. First, the first vibration generator 111 and the second vibration generator 112 are spaced apart from each other.

The first vibration generator 111 and the second vibration generator 112 are positioned on the upper surfaces of the first turntable 191 and the second turntable 192 so as to be coupled to the first turntable 191 and the second turntable 192, respectively. do.

Both ends of the frame member 120 are coupled to upper portions of the first vibration generator 111 and the second vibration generator 112 using bolts and nuts, respectively.

Then, the sensor 132 of the sensor 130 is brought into close contact with the upper surface of the frame member 120 by magnetic force.

In this state, the vibration is sensed while changing the vibration intensity of the first vibration generator 111 and the second vibration generator 112, respectively (S110). That is, the vibration intensity of the first vibration generator 111 and the second vibration generator 112 is changed, respectively, and the vibration generated in the frame member 120 is sensed through the sensor 132 of the sensor 130.

Do (S120). That is, the frame member 120 coupled to the upper portions of the first vibration generator 111 and the second vibration generator 112 is separated, and the second vibration generator 112 is rotated 90 degrees. While the second vibration generator 112 is rotated, both ends of the frame member 120 are coupled to the upper portions of the first vibration generator 111 and the second vibration generator 112 using bolts and nuts, respectively. In addition, the first turntable 191 and the second turntable 192 are fixed to the base member 150 by using fixing members 191-1 and 192-1 with bolts and nuts.

Both ends of the frame member 120 may be coupled to the centers C1 and C2 of the first turntable 191 and the second turntable 192, respectively. That is, the coupling parts of both ends of the frame member 120 and the plurality of vibration generators 111 and 112 are located at the centers C1 and C2 of the first turntable 191 and the second turntable 192, respectively. In this state, the plurality of vibration generators 111 and 112 each generate vibration.

Accordingly, each rotation direction of the first turntable 191 and the second turntable 192 can be finely adjusted. Vibration directions of the first vibration generator 111 and the second vibration generator 112 can also be finely adjusted, so that various vibration data information according to each vibration direction can be obtained.

In this way, the vibration directions of the first vibration generator 111 and the second vibration generator 112 vibrate differently from each other, and the vibration generated through the frame member 120 coupled thereto is transmitted to the sensor of the sensor 130 ( 132). The direction of the second vibration generator 112 is continuously changed to 180 degrees and 270 degrees, and the vibration generated through the frame member 120 is sensed.

In this way, in a state where the distance between the first vibration generator 111 and the second vibration generator 112 is adjusted, the vibration generated by closely contacting the sensor 132 of the sensor 130 with the upper surface of the frame member 120 detect

When the distance between the first vibration generator 111 and the second vibration generator 112 is narrowed, the vibration can be sensed by replacing the frame member 122 with a small length, and the frame member 120 is a rail relative to the plane. It is located above the member 140.

The first vibration generator 111 and the second vibration generator 112 have a first turntable 191 and a second turntable 192 coupled to the rail member 140 to prevent their own vibration, and the fixing member 191 -1, 192-1) may be fixed to the base member 150.

After changing the distance between the first turntable 191 and the second turntable 192, changing the intensity and direction of vibration, and sensing the vibration, the controller 170 controls the vibration transmitted through the frame member 120. Vibration data is received from the sensor 130 that detects vibration data, collected, analyzed, and stored in the storage device 180. Further, the controller 170 may determine whether specific abnormal vibration data is failure vibration data that causes a failure from the vibration data stored in the storage device 180 and form a database. Here, the regulation refers to defining specific abnormal vibration data as failure vibration data that causes a failure.

Since specific abnormal vibration data is defined as fault vibration data that causes a failure, and when the specific fault vibration data is detected in an operating facility, it can be determined that a failure of the operating facility has occurred. there is. Here, foreknowledge refers to the controller providing a signal or information warning of the occurrence of a failure of an operating facility.

A number of sensors are installed on the operating facility and vibration data is collected to continuously grasp the operating facility status.

The controller analyzes the performance and operating characteristics of the operating equipment and can be controlled to calculate the remaining life of key parts. The controller can capture abnormal signs of the operating equipment in advance by comparing and analyzing the databased data and the vibration data generated in the normal state of the existing operating equipment and the vibration data generated when a failure occurs. The controller can prevent the failure of the operating equipment by foreseeing the occurrence of a failure when abnormal vibration data different from the vibration data generated in the operating equipment operating normally is detected.
