The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. To fully disclose the scope of the invention to those skilled in the art, and the invention is only defined by the scope of the claims. Like reference numerals refer to like elements throughout the specification.

Hereinafter, a test apparatus for testing a smartphone according to an embodiment of the present invention will be described in detail with reference to FIGS. 1 and 2. FIG.

The testing device for testing a smartphone according to an embodiment of the present invention is for testing whether or not the device operates normally and functions normally after manufacturing or repairing an electronic device. The inner space may be formed in a shielding structure so as to be realized. Here, the electronic device includes a portable communication terminal and the like, and may be, for example, a smart phone.

The test apparatus for a smartphone test is characterized in that the lid part is slidably coupled to the main body part so that the electronic equipment accommodated in the accommodation space can be easily pulled in and pulled out.

Hereinafter, the test apparatus 1 for testing a smartphone will be described in detail with reference to Figs. 1 and 2. Fig.

FIG. 1 is a perspective view illustrating a test apparatus for testing a smartphone according to an embodiment of the present invention, and FIG. 2 is an exploded perspective view of the test apparatus for testing a smartphone of FIG. 1.

The test apparatus 1 for testing a smartphone according to the present invention includes a main body 10, a lid 20, a cylinder unit 30, a plate 40, a sealing member 50, (60).

The main body portion 10 is a tubular member whose one side is opened, and a receiving space 10a for accommodating an electronic device (see Fig. 4A) can be formed therein. The side surface of the main body portion 10 can be opened and the receiving space 10a can communicate with the outside through the open side surface of the main body portion 10. [ Although the main body portion 10 is shown as being formed in a rectangular tubular shape on the drawing, the shape of the main body portion 10 is not limited thereto, and the shape of the main body portion 10 may be variously modified. For example, the body portion 10 may be formed into a square tubular shape or a cylindrical shape. The accommodating space 10a is opened and closed by the lid part 20.

The lid portion 20 is a plate-shaped member having a predetermined thickness and is slidably coupled to the opened side surface of the body portion 10 to open and close the accommodation space 10a. For example, when the lid portion 20 is brought into close contact with the opened side surface of the main body portion 10, the receiving space 10a is sealed, and conversely, the lid portion 20 is separated from the open side surface of the main body portion 10 When released, the accommodation space 10a is opened. The lid portion 20 is slidably coupled to the main body portion 10 so that the electronic device A accommodated in the accommodation space 10a can be easily pulled in and out. The lid portion 20 is slidably moved by the cylinder unit 30.

The cylinder unit 30 has one side connected to the main body 10 and the other side connected to the lid 20 to connect the main body 10 and the lid 20, The portion 20 can be slid in the horizontal direction. For example, when the length of the cylinder unit 30 is extended, the lid portion 20 is separated from the open side of the body portion 10 to open the accommodation space 10a, and the length of the cylinder unit 30 The lid part 20 can be brought into close contact with the opened side surface of the main body part 10 to seal the accommodation space 10a. The cylinder unit 30 is formed in the form of a pneumatic cylinder and includes a cylinder 31 and a piston 32.

The cylinder 31 is a tubular member whose one side is opened and can be coupled to the outer surface of the main body 10 along the longitudinal direction of the main body 10 (see the y direction in FIG. 1). The cylinder 31 is disposed so that one side of the cylinder 31 faces the lid part 20 and can be coupled to one side surface and the other side of the main body 10 in pairs. At this time, the cylinder 31 may be coupled to the main body 10 by a separate fixing device. Each cylinder 31 receives a piston 32 therein. The piston 32 is a bar or rod-shaped member, one side of which is engaged with the lid portion 20, and the other side of which is slidable inside the cylinder 31. For example, when a fluid such as air is injected into the cylinder 31, the piston 32 may move and partly protrude outwardly of the cylinder 31. Accordingly, the lid 20 also slides The accommodation space 10a can be opened. In contrast, when the fluid in the cylinder 31 is discharged, the piston 32 can be moved and some of the piston 31 can be received inside the cylinder 31. Accordingly, the lid 20 also slidably moves in the accommodating space 10a, .

A plate (40) is connected to the lid part (20). The plate 40 is a plate-like member on which the electronic device A is seated and can be connected to one surface of the lid portion 20 contacting the main body portion 10 and horizontally extended to the inside of the accommodation space 10a . That is, the lid part 20 is slid in the horizontal direction together with the plate 40 and can open and close the accommodation space 10a. The plate 40 may have a through hole 40a on one side of the upper surface on which the electronic device A is mounted and the through hole 40a may be formed smaller than the area of the electronic device A. [ Since the through hole 40a is formed in the plate 40, there is no obstacle for blocking the radio wave between the communication module 60 and the electronic device A to be described later, so that the radio wave can be smoothly transmitted and received.

A sealing member (50) is interposed between the main body (10) and the lid part (20). The sealing member 50 is provided for sealing the accommodation space 10a to maintain airtightness and may be coupled to at least one of the body 10 and the lid 20. [ For example, the sealing member 50 may be formed of a resilient rubber plate and may be joined along the open side edge of the body portion 10 or along the side edges of the lid portion 20 contacting the body portion 10 Can be combined. It is possible to prevent the external radio waves from flowing through the gap between the main body portion 10 and the lid portion 20 by sealing the sealing space 50a with the accommodating space 10a.

The main body 10 has a plurality of communication modules 60 installed therein. The communication module 60 transmits and receives radio waves to and from the electronic device A and radiates radio waves through an antenna (not shown), controls the frequency band and output of the radio waves to be radiated, Can be measured. Since the communication module 60 is a technology known in a conventional test device for testing a smartphone, detailed description of its structure and function will be omitted. The communication module 60 is formed in a plurality of units and can be disposed on the lower portion, the upper portion, the side portion, the front portion, and the rear portion, respectively, of the plate 40 on which the electronic device A is mounted. At this time, the communication module 60 disposed at the lower portion of the plate 40 can be exposed to the electronic device A through the through-hole 40a in a superposition manner with the through-hole 40a, The communication module 60 disposed at the rear side of the electronic device A may be inclined at an angle to the electronic device A. [ The plurality of communication modules 60 are disposed on the lower portion, the upper portion, the side portion, the front portion and the rear portion of the plate 40, respectively, so that the electronic device A can transmit and receive radio waves in various directions and angles, Results can be obtained.

3 to 7, a test apparatus 1 for testing a smartphone according to another embodiment of the present invention will be described in detail.

3 is an exploded perspective view of a testing device for a smartphone test according to another embodiment of the present invention.

The test apparatus 1 for testing a smartphone according to another embodiment of the present invention further includes a pressure regulator 70, a dust injector 80, and a temperature / humidity controller 90. The test apparatus 1 for testing a smartphone according to another embodiment of the present invention includes the pressure control unit 70, the dust injection unit 80, and the temperature / humidity control unit 90, Which is substantially the same as the embodiment. Therefore, the description will be focused on, but unless otherwise noted, the description of the remaining components is replaced by the foregoing.

The inner space of the accommodation space 10a can be regulated by the pressure regulator 70. The pressure regulating unit 70 may be installed inside or outside the main body 10 to adjust the internal pressure of the accommodating space 10a to realize different environmental conditions. For example, the pressure regulating unit 70 may include at least one pump 71, and may be configured to inject compressed air into the receiving space 10a to implement an environmental condition of high pressure, The compressed air can be discharged to the outside, thereby realizing the low-pressure environmental condition. The pressure regulating part 70 can perform the performance test of the electronic device A under the environmental condition in which the pressure is higher or lower than the atmospheric pressure by adjusting the internal pressure of the accommodating space 10a, ) Can be performed more precisely. The main body 10 may be provided with a pressure measuring sensor 71 therein and the pressure regulating part 70 and in particular the pump 71 may be interlocked with the pressure measuring sensor 71 to detect the inside of the accommodating space 10a Pressure can be adjusted. As shown in the figure, when the pressure regulating part 70 is provided outside the main body 10, the pump 71 communicates with the accommodation space 10a through a separate pipe to inject or discharge the compressed air. have. Since the sealing member 50 is interposed between the main body 10 and the lid 20, the accommodation space 10a is completely sealed and the pressure can be easily controlled. However, the pressure regulating unit 70 is not limited to injecting or discharging compressed air to regulate the internal pressure of the accommodating space 10a, and may be modified into various structures capable of regulating the internal pressure of the accommodating space 10a .

A dust injecting unit 80 may be connected to one side of the main body 10. The dust injecting unit 80 injects fine dust into the inside of the main body 10, that is, the receiving space 10a to realize an environmental condition in which the concentrations of fine dusts are different from each other. As shown in FIG. For example, the dust injecting unit 80 injects a large amount of fine dust into the receiving space 10a to realize an environmental condition with high concentration of fine dust, or injects a small amount of fine dust into the receiving space 10a Thereby realizing an environmental condition in which the concentration of fine dust is low. It is possible to perform the performance test of the electronic device A under the environmental conditions in which the concentration of the fine dust is high or low by injecting the fine dust into the accommodation space 10a by the dust injecting portion 80, A) can be performed more precisely. The dust injecting unit 80 may be a device for generating fine dust or a tank in which a large amount of fine dust is stored and may be connected to the dust concentration measuring sensor 81 installed in the main body 10, The concentration of fine dust can be adjusted. As shown in the drawing, when the dust injecting unit 80 is installed outside the main body 10, it can communicate with the receiving space 10a through another pipe to inject fine dust. At this time, since the sealing member 50 is interposed between the main body 10 and the lid 20, fine dust injected into the receiving space 10a can be prevented from flowing out.

A temperature / humidity control unit 90 may be connected to one side of the main body 10. The temperature and humidity control unit 90 may be installed inside or outside the main body 10 to adjust the temperature and humidity of the inside of the main body 10 to realize an environmental condition different in temperature and humidity. The temperature and humidity control unit 90 includes an air injection unit 91 and a water injection unit 92.

The air injecting unit 91 can adjust the temperature of the accommodation space 10a to realize environmental conditions different from each other. The air can be heated or cooled and injected into the accommodation space 10a. For example, the air injecting unit 91 injects the heated air into the receiving space 10a to realize a high-temperature environmental condition, or injects the cooled air into the receiving space 10a, Conditions can be implemented. The air injection unit 91 can perform the performance test of the electronic device A under the environmental conditions of high or low temperature by adjusting the internal temperature of the accommodation space 10a, The performance test can be performed more precisely. The air injection unit 91 may be a device for heating and cooling the air or a tank for storing the heated air and the cooled air and may be interlocked with the temperature measurement sensor 91c provided in the main body 10 to provide the accommodation space 10a can be adjusted. As shown in the figure, when the air injecting unit 91 is installed outside the main body 10, the heated air or the cooled air is introduced into the receiving space 10a through the air injecting tube 91a . The air injection pipe 91a is provided with an injection nozzle 91b at an end communicating with the accommodation space 10a and can inject heated air or cooled air through the injection nozzle 91b. At this time, since the sealing member 50 is interposed between the main body 10 and the lid 20, it is possible to prevent the inflow of the introduced air into the receiving space 10a.

The water injecting unit 92 can adjust the humidity of the receiving space 10a to realize environmental conditions different from each other in humidity and atomize and spray moisture into the receiving space 10a. For example, the water injecting unit 92 may spray a large amount of water into the receiving space 10a to implement a high humidity environment, spray a small amount of water into the receiving space 10a, Can be implemented. It is possible to perform the performance test of the electronic device A under the environmental conditions of high humidity or low humidity by atomizing and spraying moisture into the accommodation space 10a by the water injecting portion 92, Can be performed more precisely. The moisture injector 92 is operable with the humidity sensor 92a provided in the main body 10 to adjust the humidity inside the accommodation space 10a. As shown in the figure, when the water injecting unit 92 is installed outside the main body 10, the water can be sprayed by communicating with the receiving space 10a through a separate pipe. At this time, since the sealing member 50 is interposed between the main body 10 and the lid 20, it is possible to prevent the infused water from flowing out into the receiving space 10a.

The dust injection unit 80 is connected to the air injection pipe 91a of the air injection unit 91 and can spray fine dust through the injection nozzle 91b of the air injection unit 91. [ In other words, fine dust supplied from the dust injecting unit 80 may be mixed with air flowing through the air injecting tube 91a and injected into the receiving space 10a together with the air through the injecting nozzle 91b. The fine dust is mixed with air and injected into the accommodation space 10a so that the performance test can be performed under the environmental conditions that are as close as possible to the atmospheric environment in which the electronic device A is actually used. The dust injecting unit 80 can inject fine dust in a state in which the accommodation space 10a is maintained at a negative pressure and the accommodation space 10a is filled with the pump 71 of the pressure adjusting unit 70 It can be maintained at a negative pressure. Fine dust can be injected smoothly without a separate pressurizing device such as a pump by injecting fine dust in a state in which the dust injecting portion 80 is held at a negative pressure by the accommodation space 10a and a separate pressurizing device is omitted The device configuration can be simplified and the installation and maintenance costs can be reduced.

In addition, the pressure regulator 70 may maintain the internal temperature below the dew point by lowering the internal pressure of the accommodation space 10a after the water injector 92 sprayed water. The pressure regulating unit 70 keeps the internal temperature below the dew point by lowering the internal pressure of the accommodation space 10a after the water is sprayed so that water in the air contained in the accommodation space 10a becomes tangled with each other and becomes a fine waterdrop Fog can be formed. Since the fog is formed inside the accommodation space 10a, the environmental condition can be implemented as closely as possible to the atmospheric environment in which the electronic device A is actually used, so that the performance test can be performed more precisely.

Hereinafter, with reference to FIG. 4 to FIG. 7, the operation of the test apparatus 1 for testing a smartphone according to another embodiment of the present invention will be described in more detail.

4 to 7 are operation diagrams for explaining the operation of the test apparatus for testing a smartphone according to another embodiment of the present invention.

The test apparatus 1 for testing a smartphone according to another embodiment of the present invention can adjust the temperature, humidity, pressure, etc. of the accommodation space 10a in which the electronic apparatus A is accommodated, It is possible to test the performance of the electronic device (A) under the environmental conditions that are as close as possible to the used atmospheric environment, thereby obtaining highly reliable test result values.

FIGS. 4 and 5 are views showing a state in which the environmental conditions before the performance test are implemented, FIG. 6 is a view showing the progress of the performance test, and FIG. 7 is a view after the performance test is completed .

4 and 5, an environmental condition can be implemented so that the internal condition of the accommodation space 10a is as close as possible to the atmospheric environment before the performance test of the electronic device A is performed.

The electronic device A is mounted on the upper surface of the plate 40 so as to be overlapped with the through hole 40a and the lid part 20 connected to the plate 40 is brought into close contact with the open side surface of the main body part 10, (10a). At this time, the sealing member 50 interposed between the main body 10 and the lid 20 can completely seal the accommodation space 10a to maintain airtightness.

For example, when the performance test is performed by adjusting the temperature and the concentration of the fine dust, as shown in FIG. 4, the dust receiving portion 80 and the air injecting portion 91 May operate. The dust injecting unit 80 injects fine dust into the main body 10 while the accommodation space 10a is maintained at a negative pressure and the air injecting unit 91 injects fine air into the main body 10, Cooled air can be injected. Since the dust injection unit 80 is connected to the air injection pipe 91a, fine dust and air can be injected together through the injection nozzle 91b. In this case, when a large amount of heated air is injected together with the fine dust, it is possible to realize an environmental condition in which both the temperature and the fine dust concentration are high. When a small amount of cooled air is injected together with the fine dust, It is possible to realize an environmental condition in which the concentration of dust is low. The dust injecting unit 80 may adjust the amount of fine dust injected in conjunction with the dust concentration measuring sensor 81 installed in the main body 10 and the air injecting unit 91 may include a temperature measuring sensor 91c, The amount of air to be injected can be adjusted.

5, when the pressure and the humidity are adjusted, the pressure regulating unit 70 and the water injecting unit 92 may be operated. The pressure regulating part 70 regulates the pressure inside the accommodation space 10a by injecting or discharging compressed air and the water injection part 92 atomizes water into the accommodation space 10a and spray it. In this case, when the pressure regulating unit 70 lowers the internal pressure of the containing space 10a to maintain the internal temperature below the dew point after the water injecting unit 92 sprayed the water, It can also be implemented. The pressure regulating unit 70 controls the injection or discharge amount of the compressed air in conjunction with the pressure measuring sensor 71 and the water injecting unit 92 can adjust the amount of water sprayed in conjunction with the humidity measuring sensor 92a have.

When the environmental conditions are implemented similar to the atmospheric environment in which the electronic device A is used, the communication module 60 can operate as shown in Fig. Since a plurality of communication modules 60 are disposed on the lower portion, the upper portion, the side portion, the front portion, and the rear portion of the plate 40, it is possible to transmit and receive radio waves to and from the electronic device A in various directions and angles, . As described above, since the electronic device A is seated on the upper surface of the plate 40 so as to overlap with the through-hole 40a, transmission and reception of the radio waves are smoothly performed with the communication module 60 located at the lower portion of the plate 40 .

When the performance test is completed, as shown in Fig. 7, the cylinder unit 30 is extended to move the lid 20 and the plate 40 in the horizontal direction. The accommodating space 10a is opened as the cover 20 and the plate 40 move in the horizontal direction and the electronic device A is pulled out from the accommodating space 10a through the open side of the main body 10 .
