Description

Surface sinking measurement method and measuring device thereof

The invention relates to a method for measuring the amount of surface sinking, in particular to a method for measuring the amount of surface sinking applied to rapid detection.

In the prior art, in order to obtain the information on the surface sinking amount of the device (for example, the server main body), the measurement is generally performed by using a thin gauge with a visual measurement, or by using a single-point digital electronic meter. Measurement.

The measurement with the thickness gauge and the visual inspection method has extremely poor accuracy and measurement efficiency, and cannot effectively quantify and standardize the measurement methods and criteria, and the measurement results cannot be digitized.

The use of a single-point digital electronic scale to measure the amount of sinking has the advantage of being able to digitize the measurement results, but because this method is a single-point measurement, it is necessary to measure the amount of the underlying surface of the entire chassis. The time is relatively long. In addition, the single-point digital electronic scale is a contact type measuring instrument, so the contact probe of the measuring meter has a wear life problem. And it may scratch the surface of the object to be tested.

A surface sinking measuring device for measuring the amount of sinking of a surface of a casing, comprising a support frame, a light source, a receiver and a control unit. The support frame supports the device. The light source provides a light, wherein the light source is in a reference plane that travels in a horizontal direction. The receiver receives the light, wherein the receiver is located in the reference plane, and when the sinking amount of the casing surface of the device exceeds an allowable value, the casing surface interferes with the reference plane to prevent the receiver from receiving the light. Light. The control unit is coupled to the receiver, and the control unit determines whether the surface of the casing of the device has a sinking amount exceeding an allowable value according to whether the receiver receives the light.

Surface sinking measuring device and surface matched with the embodiment of the invention The sinking amount measuring method can directly detect the sinking amount of the casing surface and the damage rate of the equipment is extremely low compared to the measuring method of the single-point digital electronic meter. Compared with the measurement method with the thick gauge and the visual inspection, the surface sinking measurement method of the embodiment of the present invention can specifically quantify the detection result, and can establish a stable detection step and a criterion. Therefore, the surface sinking measurement method of the embodiment of the present invention provides a fast detection speed and an accurate and stable measurement result as compared with the prior art.

Referring to Fig. 1, when the amount of sinking of the casing surface 21 of the apparatus 2 exceeds an allowable value, the casing surface 21 interferes with the reference plane B to prevent the receiver 13 from receiving the light 121. Referring to Fig. 2, when the sinking amount of the casing surface 21 of the apparatus 2 does not exceed the allowable value, the casing surface 21 does not interfere with the reference plane B, and the receiver 13 receives the light. 121. The control unit is coupled to the receiver 13, and the control unit determines whether the chassis surface 21 of the device 2 has a sinking amount exceeding an allowable value according to whether the receiver 13 receives the light 121. For example, in FIG. 1, since the receiver 13 does not receive the light ray 121, it can be judged that the casing surface 21 has a sinking amount exceeding the allowable value; in the second figure, since the receiver 13 receives The light 121 can be judged that the casing surface 21 does not have a sinking amount exceeding the allowable value at the detected position.

Referring to FIG. 3, in this embodiment, the surface sinking measuring device 1 further includes a first rail 14 and a second rail 15, the first rail 14 is parallel to the second rail 15, and the light source 12 is disposed on The first rail 14 is disposed on the second rail 15 . The light source 12 moves along the first guide rail 14 on the reference plane B. The receiver 13 moves on the second guide rail 15 in a manner corresponding to the light source 12. Thereby, a single dimension of detection can be provided, and the control unit determines, according to whether the receiver 13 receives the result of the light ray 121, where the shell surface 21 of the device 2 has a sinking amount exceeding a single dimension. The case of allowable values.

In this embodiment, the light source 12 is an infrared light source, which may also be other types of linear light sources, such as lasers. In an embodiment, the light source 12 is driven by the stepping motor on the first rail 14, the receiver 13 is driven by the stepping motor on the second rail 15, and the control unit is coupled to the stepping motor. Since the stepping motor has a stroke encoding and feedback function, the control unit can precisely control the position of the light source 12 and the receiver 13, and thereby determine where the casing surface 21 of the device 2 exists in a single dimension. The case where the sinking amount exceeds the allowable value.

The device 2 includes two lugs 22 formed on opposite sides of the device 2, respectively. The support frame 11 includes two support portions 111 that support the lugs 22, respectively. In this embodiment, the support portions 111 are L-shaped structures. The design of the lug prevents the support from interfering with the light source to ensure smooth detection.

In an embodiment, after one-dimensional detection is performed to obtain the sinking amount information of the casing surface 21 of the device 2 in a single dimension, the device can be horizontally rotated by 90 degrees, and the light source 12 and the receiving source are again received. The device 13 performs another dimension detection on the surface 21 of the casing to obtain the information on the surface sinking amount of the entire plane (two-dimensional) of the casing surface 21.
