Description

The present invention relates to a tilt correction device for correcting the tilt of an electronic device placed on a gel damper.

Many electronic devices use precision parts that are vulnerable to vibration. Therefore, when an electronic device is installed in a place where vibration is a concern, such as a control plant or a ship, it may be necessary to take anti-vibration measures to protect the electronic device (see Patent Document 1, for example). Representatives of such electronic devices include power supplies and industrial personal computers. These electronic devices weigh about 5 to 20 kg and are generally housed in dedicated cabinets or enclosures. When the parts used in these electronic devices are exposed to long-term vibration, friction or cracking occurs, causing deterioration and failure. For example, when a power supply device is exposed to vibration for a long period of time, the power supply winding, which is a heavy-duty component, may move slightly, causing fine scratches on the insulating coating, which may lead to ignition.

In addition, recent electronic components have become smaller and thinner, and are vulnerable to mechanical stress, which may lead to cracks or short-circuit failures. In some cases, the electronic device manufacturer indicates the vibration limit value, but it is difficult to accurately grasp the vibration state at the installation site of the electronic device. Countermeasures are taken.

As a countermeasure against vibration, in general, anti-vibration rubber is often placed under electronic equipment. Anti-vibration rubber comes in various shapes and hardness types, and is often used for heavy and large machine tools. And, due to the elasticity of this anti-vibration rubber, an effect of reducing vibration and preventing noise can be expected.

On the other hand, in electronic equipment including precision equipment or precision electronic components, if continuous vibrations are applied, the precision equipment or electronic components are degraded or damaged. In order to prevent this, anti-vibration rubber is insufficient, and a gel-like damper (gel damper) is sometimes used.

A gel damper is made of elastic resin elastomer material such as rubber, and can be made from soft to hard depending on the material distribution. This gel damper has the effect of effectively reducing and damping vibrations by adjusting the load and resonance frequency. This gel damper is sticky and can be expected to have a stable vibration damping effect by being sandwiched between the base and the electronic device. A gel damper having a thickness of about 20 to 50 mm is used as the gel damper in order to obtain a sufficient anti-vibration effect.

JP 2011-179675 A

However, as shown in FIG. 11, this gel damper gradually sinks while supporting a heavy object. For example, even if the gel damper has a thickness of about 30 mm in the initial state, it may have a thickness of about 20 to 25 mm after several months. The sinking of the gel damper does not affect the anti-vibration effect, but the sinking causes the electronic device to tilt, resulting in poor stability. This may affect the operation of some electronic devices. It should be noted that the degree of sinking of the gel damper varies depending not only on the applied load but also on the environment such as temperature and humidity.
In FIG. 11, reference numeral 10 indicates a gel damper, and reference numeral 20 indicates an electronic device.

Note that the layout of parts in an electronic device is determined by electrical functional blocks, so weight balance is not taken into consideration. Therefore, in electronic devices, weight deviation occurs. Heavy objects mounted on electronic devices include, for example, transformers and storage batteries. The PC is also a unit with heavy power supply components.

In this way, when multiple gel dampers are used as anti-vibration measures for electronic equipment, since the load applied to each gel damper is not constant, the amount of sinking of each gel damper will differ over time, and the electronic equipment will be damaged. will tilt. In addition, in precision equipment or electronic equipment including precision electronic components, if the tilt exceeds a certain level (more than the allowable value), it may lead to malfunction. For example, a hard disk or optical disk is required to be horizontal or vertical. It is also desirable that the storage battery or the like be horizontal when liquid is contained. In this way, precision instruments or electronic instruments including precision electronic components are desirably used horizontally, so it is necessary to correct the tilt.

If the gel damper is arranged in consideration of the center of gravity of the electronic device, variations in sinking will be reduced. However, this arrangement cannot be adopted because it does not necessarily have a good vibration isolation effect. In other words, where the gel damper is pressed affects the vibration damping effect. For example, it may be more effective to place a gel damper near screws that fix internal parts, or to place a gel damper near parts that are vulnerable to vibration.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
Embodiment 1.
1 and 2 are diagrams showing a configuration example of a tilt correcting device according to Embodiment 1. FIG.
The tilt correction device corrects the tilt of the electronic device 20 placed on the gel damper 10 . One or more gel dampers 10 are provided for one electronic device 20 .
The electronic device 20 shown in FIGS. 1 and 2 is placed on four gel dampers 10 arranged at positions facing each other at the four corners. The tilt correcting device includes a mounting table 1, a moving mechanism 2, a detector 3 and a controller 4, as shown in FIGS. In FIG. 2, illustration of the moving mechanism 2, the control unit 4, and their connection lines is omitted.

The mounting table 1 is a table on which the gel damper 10 is placed. Two or more mounting tables 1 are provided for one electronic device 20 . FIGS. 1 and 2 show a case where a mounting table 1 is provided for each gel damper 10. FIG.

The moving mechanism 2 enables the mounting table 1 to move in the vertical direction (the direction of gravity). 1 and 2, the moving mechanism 2 has a motor 21 and a screw mechanism 22. As shown in FIG.

The screw mechanism 22 is driven by the motor 21 to vertically move the mounting table 1 . 1 and 2, the screw mechanism 22 consists of a long thread and a female thread. The female threaded portion is formed on the mounting table 1 and is a portion into which the long screw is screwed. The screw mechanism 22 shown in FIGS. 1 and 2 vertically moves the mounting table 1 connected to the long screw through the female screw by rotating the long screw by the motor 21 .

The detector 3 detects parameters related to the tilt of the electronic device 20 placed on the gel damper 10 . In FIGS. 1 and 2, a tilt sensor 31 is used as the detection section 3 .
The tilt sensor 31 is placed on the electronic device 20 and measures the tilt of the electronic device 20 .

The control unit 4 controls the moving mechanism 2 to correct the tilt of the electronic device 20 based on the detection result by the detection unit 3 . At this time, for example, the control unit 4 moves downward (downward in the direction of gravity) the moving mechanism 2 on the side of the electronic device 20 where the sinking has not occurred among the moving mechanisms 2 .
1 and 2, based on the tilt of the electronic device 20 detected by the tilt sensor 31, the control unit 4 controls the moving mechanism 2 to correct the tilt of the electronic device 20. FIG.

The control unit 4 is implemented by a processing circuit such as a system LSI (Large Scale Integration) or a CPU (Central Processing Unit) that executes programs stored in a memory or the like.

Next, an operation example of the tilt correcting device according to the first embodiment shown in FIGS. 1 and 2 will be described.
As shown in FIG. 3A , immediately after the electronic device 20 is placed on the gel damper 10 (initial state), the difference in sinking of the gel damper 10 is small, and the electronic device 20 is installed substantially horizontally. The gel damper 10 is self-adhesive.

However, as shown in FIG. 3B, the amount of sinking of the gel damper 10 to which a large load is applied increases (the gel damper 10 is compressed) due to the passage of time, the influence of the ambient temperature, or the like. At this time, usually, sinking occurs in a certain direction due to the arrangement of heavy objects inside the electronic device 20 . As a result, the electronic device 20 is tilted. In FIG. 3B, as indicated by reference numeral 301, the gel damper 10 on the left has more subsidence.
Therefore, as shown in FIG. 3C, in the inclination correcting device according to the first embodiment, this defect is compensated for by changing the height of the mounting table 1 of the gel damper 10. FIG. In FIG. 3C , as indicated by reference numeral 302 , the height difference between the left and right gel dampers 10 is eliminated by lowering the position of the right gel damper 10 .

That is, in the tilt correction device according to the first embodiment, as shown in FIG. 4, when the electronic device 20 sinks by a certain amount or more (for example, 3 mm or more), the detection unit 3 detects a parameter related to the tilt. In the tilt correction device according to Embodiment 1, the tilt sensor 31 is used as the detector 3, and the tilt sensor 31 directly measures the tilt of the electronic device 20. FIG.

Then, as shown in FIG. 5 , the control unit 4 controls the moving mechanism 2 based on the detection result of the detection unit 3 so as to eliminate the inclination of the electronic device 20 . At this time, for example, the control unit 4 drives the moving mechanism 2 on the side opposite to the side on which the sinking (inclination) is detected, and controls the mounting table 1 to be lowered. In the configuration shown in FIGS. 1 and 2, the control unit 4 turns on the motor 21, rotates the long screw, and lowers the mounting table 1 to a predetermined position (the non-sinking side), thereby moving the electronic device 20. Level.

It should be noted that, as shown in FIG. 6, when sinking occurs again, the inclination correcting device according to the first embodiment repeats the same processing as described above. Thereby, the horizontality of the electronic device 20 is maintained.

In addition, when a plurality of gel dampers 10 are used for the electronic device 20, the control unit 4 performs adjustment according to the position of the gel damper 10 that has sunk most.

4 to 6, the control unit 4 drives the moving mechanism 2 on the opposite side of the moving mechanism 2 to the side on which the sinking (inclination) is detected, and controls the mounting table 1 to be lowered. , shows the case where the electronic device 20 is horizontal. However, the present invention is not limited to this, and the control unit 4 drives the moving mechanism 2 on the side of the moving mechanism 2 that has detected the sinking (inclination) so as to raise the mounting table 1, whereby the electronic device 20 can be horizontal.

As described above, according to the first embodiment, the tilt correcting device includes the mounting table 1 on which the gel damper 10 is placed, the moving mechanism 2 that allows the mounting table 1 to move in the direction of gravity, and the gel damper 10.
