Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an apparatus and a method for measuring an airtightness of an electronic device,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a method of confirming a sealed state, that is, a waterproof state, such as a sealing of a case of an electronic device such as a portable terminal, ≪ / RTI >

Currently, waterproof standards for electronic devices such as portable mobile communication devices, tablet PCs, and smart phones are tested by a manufacturer in order to satisfy the IP rating of the waterproofing standard established by the International Electrotechnical Commission (IEC) have.

The IP standard waterproof test method is to test the immersion trace (IPX7, 8 grade) after leaving the electronic device in water tank of a certain depth for several tens of minutes, to carry out the waterproof test with the machine using air pressure called WPC, By applying the sensor, it is judged by the pressure value of the inside according to the external pressurization. That is, there are three concrete methods for the conventional waterproof test.

The first method is a water tank test, which is a test to meet IPX7 or above among international IP standards IPX1 ~ 8. It is a method to confirm the immersion trace by leaving it in a water tank of 1 [m] depth for 30 [minutes].

The second method is the WPC air pressure waterproofing test. The electronic device is installed in the test equipment by using the WPC equipment, and the waterproof state is diagnosed through the pressure value measured by the external pressure.

The third method is an experiment using an air pressure sensor mounted inside the electronic device. The air pressure sensor is mounted on the PCB of the electronic device, and the difference of the atmospheric pressure change in the electronic device is read from the air pressure sensor, Thereby making it possible to judge the waterproof state of the electronic device.

In practice, the third way to check the waterproof performance of a product is to use an air pressure sensor to confirm the product and a second method to check the change in air pressure in an expensive measuring device.

However, when the air pressure sensor is attached to the electronic device to confirm the waterproof function through the third method, there is a problem that the unit price of the product increases. Further, since the air pressure sensor is mounted on the PCB, a measurement error occurs due to the pattern around the air pressure sensor. That is, the measured value of the air pressure sensor may be erroneously increased due to an increase in capacitance due to the peripheral GND, a DC / DC power source noise, or a temperature change of peripheral chips. In addition, there is a problem that, in case of poor reception at a service center due to poor waterproofing, it is not possible to confirm beforehand whether or not a defective LCD is defective due to a consumer error due to defective products.

On the other hand, when the second method is applied, the measurement equipment must be installed in the mass production line and the service center, thus causing a problem of cost increase and space reservation for the purchase and setup of the measurement equipment.

An object of the present invention is to provide a measurement and analysis apparatus and method for an airtightness diagnosis of an electronic apparatus for analyzing an airtightness of an electronic apparatus using an external measurement module and storing and outputting an analysis result of an airtight state will be.

According to an aspect of the present invention, there is provided a measurement apparatus for airtightness diagnosis of an electronic apparatus, the apparatus comprising: an air pressure sensor for measuring an internal air pressure of the electronic apparatus; And a wireless communication unit for wirelessly transmitting the atmospheric pressure information measured by the atmospheric pressure sensor.

According to another aspect of the present invention, there is provided an analysis apparatus for an airtightness diagnosis of an electronic apparatus, comprising: a wireless communication unit for wirelessly receiving air pressure information on an internal air pressure of the electronic apparatus; And a processor for detecting a change in atmospheric pressure of the electronic device from the atmospheric pressure information received through the wireless communication unit for a predetermined time and analyzing the closed state of the electronic device in accordance with the detected atmospheric pressure change.

According to another aspect of the present invention, there is provided a measurement method for an airtightness diagnosis of an electronic device, the measurement device for airtightness diagnosis of the electronic device comprising: Establishing a wireless connection with the mobile terminal; For a predetermined period of time in which the predetermined pressure is applied and released to the electronic device when the terminal case of the electronic device is sealed after a predetermined pressure is applied to the electronic device on which the measurement device is mounted, Measuring a pressure in the electronic device; And wirelessly transmitting the measured atmospheric pressure information to the analyzing apparatus by the measuring apparatus.

According to another aspect of the present invention, there is provided an analysis method for an airtightness diagnosis of an electronic device, the analysis device for the airtightness diagnosis of the electronic device includes a measurement device Establishing a wireless connection with the mobile terminal; Wirelessly receiving atmospheric pressure information about an internal air pressure of the electronic device from the measurement device; And a step of detecting a change in the atmospheric pressure of the electronic device from the received atmospheric pressure information for a predetermined time and analyzing the closed state of the electronic device in accordance with the detected atmospheric pressure change.

According to the present invention, the closed state of an electronic device such as a portable mobile communication device, a smart phone, and a tablet PC can be easily confirmed.

Further, since it is not necessary to mount the air pressure sensor on the electronic circuit internal circuit board in order to confirm the closed state of the electronic device, it is possible to lower the production cost of the electronic device and to measure the air pressure sensor An error can be prevented.

In addition, since the sealed state of the electronic device can be confirmed without having expensive verification equipment for confirming the sealed state in the mass production line and the service center, it is possible to determine the defect caused by the customer's fault This can be used as a basis for data.

The wireless communication unit 600 performs short-range wireless communication with the measurement apparatus 100 using these communication modules.

The processor 610 detects a change in the atmospheric pressure of the electronic device from the atmospheric pressure information received through the wireless communication unit 600 for a predetermined time and analyzes the closed state of the electronic device according to the detected atmospheric pressure change.

The processor 610 compares the atmospheric pressure information after the lapse of the predetermined time with the atmospheric pressure to determine whether the electronic device is defective with respect to the closed state. Here, it is set to a time that the case of the electronic device is expected to be restored to the original state when the external pressure is removed after applying the external pressure to the electronic device.

The processor 610 determines that the sealed state of the electronic device is defective if the atmospheric pressure information after the lapse of a predetermined time is equal to the atmospheric pressure. If the internal pressure of the electronic device became equal to the atmospheric pressure after the external pressure applied to the sealed electronic device was removed, it means that the electronic device was equal to the atmospheric pressure due to the inflow of air to the defective sealing state. Thus, if the air pressure information of the electronic device is equal to the atmospheric pressure, the processor 610 determines that the closed state of the electronic device is defective.

Further, the processor 610 determines that the closed state of the electronic device is normal if the atmospheric pressure information after the lapse of the predetermined time has the atmospheric pressure and the predetermined air pressure difference or more.

If, after the external pressure applied to the enclosed electronic device is removed, the internal pressure of the electronic device is maintained above atmospheric pressure and above a certain pressure difference, the external air is not introduced into the electronic device due to the good sealing of the electronic device it means. Thus, if the barometric pressure information of the electronic device maintains atmospheric pressure and a constant pressure difference, the processor 610 determines that the closed state of the electronic device is normal.

In the case of the internal space volume, the larger the internal volume volume of the electronic device, the smaller the pressure change amount in the atmospheric pressure sensor in accordance with the amount of pressure. The present atmospheric pressure corresponds to the atmospheric pressure of the atmosphere of the measurement environment and depends on the altitude of the weather or the measurement environment. In addition, the pressed state according to the design structure of the electronic device corresponds to the difference in the relative pressing amount depending on the screen size when the case material of the electronic device and the display screen (for example, lcd) of the electronic device are pressed.

Also, the barometric pressure output module 710 performs a function for outputting a change amount with respect to a change in atmospheric pressure of the electronic device. For example, the air pressure output module 710 outputs an air pressure change amount for each electronic device corresponding to 1 to 4 in Fig. In the graph, it can be seen that the internal pressure of the electronic device drops rapidly when the external pressure (for example, weight) is released. Thereafter, the internal air pressure of the electronic device is shown.

In addition, the start / end selection module 720 performs a selection function for starting, stopping, or ending the analysis operation. Also, the analysis output module 730 outputs a result of analyzing the closed state of the electronic device, and outputs the result of the normal or bad state of the closed state.

7, the user interface unit 620 displays a change in atmospheric pressure for the four electronic devices in the PC on which the measurement S / W is installed by using a graph, and displays the closed state analyzed according to the atmospheric pressure change amount data So that the connection state of each measuring device can be confirmed.

To this end, the analyzing apparatus may include wireless communication units capable of simultaneously receiving a plurality of barometric pressure information, and the processor may simultaneously analyze a plurality of barometric pressure information and simultaneously determine an airtight state for each of the electronic devices. As shown in FIG. 7, the analyzer receives the atmospheric pressure information from each of the four measuring devices, simultaneously diagnoses the four electronic devices, and obtains a measurement result graph And stores the data of the atmospheric pressure value during the measurement time in the memory. Then, the analyzer analyzes each of the atmospheric pressure change amount data, determines the closed state of the electronic devices, and displays the closed state on the display screen.

Thereafter, the measuring device establishes wireless communication with the analyzing device.

The analyzer establishes a wireless connection with the measurement device using either Bluetooth communication, WiFi communication, or Infrared Data Association (IrDA) communication.

After step S900, air pressure information on the internal air pressure of the electronic device is wirelessly received from the measurement device (S902). The analyzer receives the atmospheric pressure information through one of Bluetooth communication, WiFi communication and IrDA (Infrared Data Association) communication.

After step S902, the analyzer detects a change in the atmospheric pressure of the electronic device from the received atmospheric pressure information for a predetermined time, and analyzes the closed state of the electronic device according to the detected atmospheric pressure change (S904).

The process of analyzing the closed state of the electronic device determines whether the electronic device is defective with respect to the closed state by comparing the atmospheric pressure information after the lapse of the predetermined time with the atmospheric pressure. Here, it is set to a time that the case of the electronic device is expected to be restored to the original state when the external pressure is removed after applying the external pressure to the electronic device.

The analyzing device determines that the sealed state of the electronic device is defective if the atmospheric pressure information after a lapse of a predetermined time is equal to the atmospheric pressure. If the internal pressure of the electronic device became equal to the atmospheric pressure after the external pressure applied to the sealed electronic device was removed, it means that the electronic device was equal to the atmospheric pressure due to the inflow of air to the defective sealing state. Thus, if the air pressure information of the electronic device is equal to the atmospheric pressure, the analyzing device determines that the sealed state of the electronic device is defective.

Further, the analyzing device determines that the closed state of the electronic device is normal if the atmospheric pressure information after the lapse of the predetermined time has the atmospheric pressure and the predetermined atmospheric pressure difference or more.

If, after the external pressure applied to the enclosed electronic device is removed, the internal pressure of the electronic device is maintained above atmospheric pressure and above a certain pressure difference, the external air is not introduced into the electronic device due to the good sealing of the electronic device it means. Thus, if the pressure information of the electronic device maintains the atmospheric pressure and the constant pressure difference, the analyzing device determines that the closed state of the electronic device is normal.

Here, the constant atmospheric pressure difference is set in advance according to the atmospheric pressure, the internal space volume of the electronic device, the material characteristics of the casing of the electronic device, and the magnitude of the external pressure applied to the electronic device.

As shown in Fig. 7, in the case of the electronic devices 1 and 2, when the constant air pressure difference DELTA P is maintained after a lapse of a predetermined time (for example, 20 [sec]), It is determined that the sealing state is good and the sealed state is normal. However, in the case of the electronic device 4, when the constant air pressure difference? P becomes 0 after a predetermined time (for example, 20 [sec]), that is, when the measured air pressure information and the atmospheric pressure become equal to each other, It is judged that the closed state of the apparatus is defective.

After step S904, the interface of the input of the user command and the output of the analysis result to the closed state of the electronic device is interfaced (S906).
