DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an apparatus for removing foreign objects in a mobile terminal case according to a preferred embodiment of the present invention will be described in detail with reference to FIGS. 1 to 5. FIG.

1 is a cross-sectional view illustrating an apparatus for removing foreign matter in a mobile terminal case according to an embodiment of the present invention.

As shown in FIG. 1, the foreign substance removing apparatus of the mobile terminal case according to the embodiment of the present invention includes a main body 100; A conveying conveyor unit (200) disposed on the main body (100) for conveying the mobile terminal case in a predetermined direction; And a main operation unit 300 disposed on the transmission path of the mobile terminal case for performing a charge eliminating operation and a blowing operation.

In addition, the foreign substance removing apparatus of the mobile terminal case according to the embodiment of the present invention further includes an additional operation unit 400. [ The additional operation unit 400 is disposed after the main operation unit 300 on the basis of a direction in which the mobile terminal case is transmitted. In the drawing, an additional operation unit 400 is disposed on the right side of one side of the main operation unit 300. The additional operation unit 300 performs substantially the same operation as the main operation unit 300, and a detailed description of the operation will be given later.

The main body 100 is formed in a rectangular shape having an opened top surface and provides an internal space capable of arranging the components for driving the conveying conveyor unit 200 and the conveying conveyor unit 200. The main operation unit 300 and the additional operation unit 400 are connected to the upper surface of the main body 100.

The conveying conveyor unit 200 is for conveying the mobile terminal case in a predetermined direction and includes a rotating body 210 fixed to an upper portion of the main body 100 to perform a rotating operation in a predetermined direction, A conveyor chain 220 for performing a movement operation in a predetermined direction in accordance with a rotation operation of the rotary body 210, and a drive unit 230 (see FIG. 3) for rotating the rotary body 210.

The rotating body 210 has a disk model, and teeth are formed around the circle. The rotating body 210 is connected to a rotating shaft 10 connected in the width direction of the main body 100 and the driving unit 230 rotates the rotating shaft 10 using the driving transmitting member 30. The rotation of the rotating shaft 10 means that the rotating body 210 rotates.

The conveyor chain 220 is formed by connecting a plurality of unit chains and is connected to the rotating body 210 disposed on the left and right of the upper portion of the main body 100 in a positive direction. Therefore, if the rotating body 210 rotates counterclockwise, the upper surface of the conveyor chain 220 moves in the A direction to the A 'direction.

Meanwhile, the conveyor chain 220 is connected to a plurality of jigs 230 for attaching / detaching the mobile terminal case. At this time, the conveyor chain 220 and the jig 230 are fixedly connected to each other by the jig supporting plate 30 (see FIG. 2), and the jig 230 is fixed to the conveyor chain 220 so as not to be separated .

4 is a perspective view for explaining a connection relationship between the jig supporting plate 30 and the jig 230. As shown in FIG. Here, two jigs are connected to one jig supporting plate 330. The two jigs will be referred to as a first jig 230_1 and a second jig 230_2, respectively. For convenience of explanation, the first jig 230_1 will be mainly described.

The first jig 230_1 includes a fixing part 410 fixed to the jig supporting plate 30 and a first connection part 430 connected to the fixing part 410 and coupled to the lower grip part 420, An upper grip portion 440 disposed to oppose the lower grip portion 420 to grip the mobile terminal case and a second connection portion 450 connecting the upper grip portion 440 and the operation portion 450, And an operating portion 450 for adjusting the upper grip portion 440 to be in close contact with the lower grip portion 420 by the grip portion 470. And a contact rotation part 470 connected to the first connection part 430 to rotate the lower grip part 420 and the upper grip part 440.

The second jig 230_2 is connected to the jig supporting plate 30 in the same manner as the first jig 230_1. The jig supporting plate 30 includes a member having a "C" shape for fixing the operating portion 450 of the first jig 230_1 and an operating portion (not shown) of the second jig 230_2, Shaped member and a fixing member 480 composed of a member for connecting the jig supporting plate 30 with the " C "

Hereinafter, a simple operation of the first jig 230_1 and the second jig will be described.

The operation unit 450 of the first jig 230_1 is fixed to the fixing unit 480 and the upper grip unit 440 can be moved up and down by the handle 470. [ Here, the first jig 230_1 is in a state in which the upper grip portion 440 moves downward and is in close contact with the lower grip portion 420, and the second jig 230_2 moves upward And is spaced apart from the lower grip portion.

The state in which the lower grip portion 420 and the upper grip portion 440 are in close contact with each other like the first jig 230_1 means that the mobile terminal case can be gripped and attached. The state where the second jig 230_2 is spaced apart means that the mobile terminal case can be detached and detached.

The mobile terminal case can be detached / attached through the above operation.

Then, the first and second jigs 230_1 and 230_2 are rotated for a more efficient operation in the discharge operation and the blow operation, which will be described later. At this time, the driving force necessary for rotation is transmitted through the contact rotation part 470. A method for transmitting the driving force through the contact rotation part 470 may be various. In this case, a band connected in an endless track is rotated to directly contact the contact rotation part 470 to rotate the contact rotation part 470 Do.

Thus, the connection rotation part 470 is rotated by transmitting the driving force in the above-described manner, so that the first connection part 430 and the lower grip part 420 connected thereto are rotated. At the same time, the mobile terminal case and the upper grip unit 440 rotate, and as a result, the mobile terminal case rotates together with the connection rotation unit 470.

The first connection part 430 of the first jig 430_1 and the first connection part of the second jig 430_2 are connected to the band part 40. [ Thus, when the first jig 430_1 performs a rotating operation, the second jig 430_2 also performs a rotating operation.

As a result, the mobile terminal case can be attached to and detached from the first and second jigs 230_1 and 230_2 through the above-described operation, and the first and second jigs 230_1 and 230_2 ).

Referring again to FIG. 1, a plurality of jigs 230 are connected to the conveyor chain 220 by a plurality of jig supporting plates 30, and the number and shape thereof may vary according to the designer. As described above, the jig 230 is capable of attaching / detaching the mobile terminal case. The mobile terminal case is gripped by the mobile terminal case so that the mobile terminal case is not detached from the foreign substance removal device during the removal of foreign matter remaining on the surface of the mobile terminal case.

Meanwhile, the main operation unit 300 is disposed on the conveying conveyor unit 200, performs a discharge operation on the mobile terminal case that enters the main operation unit 300, and then performs a blowing operation.

It is possible that the foreign substance removing apparatus of the mobile terminal case according to the embodiment of the present invention includes a plurality of additional operation units performing the same function as the main operation unit 300. [ In this example, one main operation unit 300 and one additional operation unit 400 are provided.

The operation of the main operation unit 300 and the additional operation unit 400 is similar to that of the internal operation and the internal operation of the main operation unit 300, so that the main operation unit 300 will be described below.

The main operation unit 300 includes a unit frame 310 disposed on the moving path of the conveying conveyor unit 200 and a discharge unit 330 (see FIGS. 2 and 3) And a discharging unit 330 for discharging the foreign matter to the outside.

The unit frame 310 provides an internal space for securing the movement path of the mobile terminal case, and the internal space may include a space for a static elimination operation and a ventilation operation.

The unit frame 310 is formed in a longitudinal direction having the same width as that of the main body 100, and a work door 40 is provided on one side of the unit frame 310, . A part of the operation door 40 comprises a viewer window 50 so that the transmission process and the process of the mobile terminal case can be viewed in real time.

The supply unit 320 is connected to the upper part of the unit frame 310 and injects air into the unit frame 310 by an air supply fan (not shown) connected to the upper part of the unit frame 310. In the inner space of the unit frame 310, a constant airflow is formed.

The exhaust unit 330 will be described with reference to the following drawings.

2 and 3 are a plan view and a side view for explaining an exhaust part 320 of the foreign substance removing apparatus of the mobile terminal case according to the embodiment of the present invention.

The exhaust unit 330 corresponding to the main operation unit 300 and the exhaust unit 430 corresponding to the additional operation unit 400 are connected to one side of the main body 100. [ Hereinafter, the exhaust unit 330 corresponding to the main operation unit 300 will be described for convenience of explanation.

The exhaust part 330 has a shell-shaped frame structure and a relatively wider part is connected to the main body 100 side. The exhaust unit 330 discharges the foreign substances generated in the internal space of the main operation unit 300 to the outside, and the foreign matter generated in the internal space is discharged to the main body 100 by the airflow formed in the internal space. And then to the exhaust part 330.

At this time, the path through which the foreign matter is discharged may be formed in the internal space of the main body 100.

Referring again to FIG. 1, the unit frame 310 has a power supply unit 311 and a power supply unit 312 disposed therein.

The electricity removing unit 311 is installed in an inner space of the unit frame 310 and performs a charge erase operation on the mobile terminal case that enters the internal space of the unit frame 310. Here, the erasing operation is an operation of ejecting a predetermined amount of negative (-) ions and positive (+) ions to the mobile terminal case at a predetermined speed to eliminate the static electricity of the foreign matter remaining on the surface of the mobile terminal case.

The blowing part 312 is also installed in the inner space of the unit frame 310 to perform a blowing operation on the mobile terminal case that has completed the defrosting operation. Here, the blowing operation refers to an operation of blowing foreign matter remaining on the surface of the mobile terminal case by blowing wind to the mobile terminal case at a predetermined period and the predetermined wind intensity in the mobile terminal case.

The order of disposing the ejector 311 and the blowing unit 312 with respect to the first direction is determined. As described above, the foreign substance removing apparatus of the mobile terminal case according to the embodiment of the present invention performs a blowing operation after the electricity removing operation. Therefore, it is preferable that the power supply unit 312 is disposed at the rear end of the power supply unit 312, and the power supply unit 312 is disposed at the rear end of the power supply unit 312. [

Meanwhile, the discharge unit 311 and the blowing unit 312 may be designed in various ways, and the position where the discharge unit 311 and the blowing unit 312 are disposed may also be disposed anywhere in the mobile terminal case if the blowing operation can be performed after the discharge operation. These configurations are all included in the foreign substance removing apparatus of the mobile terminal case according to the embodiment of the present invention.

5 is a perspective view illustrating a blowing unit 312 of a foreign substance removing apparatus of a mobile terminal case according to an embodiment of the present invention.

5, the blowing unit 312 includes an air compression unit 510 for storing and compressing air, a hose unit 520 for supplying air to the air compression unit 510, And an air control unit 520 connected between the compression unit 510 and the hose unit 520 to control air delivery from the hose unit 520 to the air compression unit 510.

An air delivery unit 540 for delivering the air compressed by the air compression unit 510 to the air discharge unit 550 and the discharge unit 550 for directly spraying wind to the mobile terminal case Respectively.

The air delivery unit 540 may be formed as a freely curved body that can freely bend. The air delivery unit 550 may perform a blowing operation to the mobile terminal case in a desired direction at a desired position It is possible.

Next, the wind-up unit 312 can control the wind intensity and the wind blowing period.

The blowing operation intensity adjusting unit 560 can adjust the wind intensity and the blowing period of the wind outputted through the blowing unit 550. Here, the blowing cycle of the wind means a time interval from when the wind blows once to when it blows again.

Referring to FIG. 1 again, the discharger 311 may be designed in various ways as in the case of the blower 312.

For example, the electricity removing unit 311 may also include a free-form body, such as the air delivery unit 540 of the air supply unit 312, to perform an erasing operation on the mobile terminal case in a desired direction It is possible. Also, the power-off unit 311 has an internal structure and has the same structure as the blowing operation intensity adjusting unit 560, thereby adjusting the setting operation intensity.

In other words, the foreign matter removing device of the mobile terminal case according to the embodiment of the present invention controls the discharge operation intensity of the power-off unit 311 of the main operation unit 300 and the air- It is possible. Here, the antistatic strength refers to the amount of negative ions and positive ions ejected from the case of the mobile terminal and the speed of ejection, and the blowing operation intensity is determined by the wind strength And the ejection period.

Subsequently, like the main operation unit 300, the additional operation unit 400 is also capable of regulating the discharge operation strength and the blowing operation strength. Hereinafter, for convenience of explanation, the static elimination operation strength and the air flow operation strength of the main operation unit 300 will be referred to as "main operation strength", and the static operation strength and the air flow operation strength of the additional operation unit 400 will be referred to as " Quot;

In other words, it is possible to adjust the main operation strength of the main operation unit 300 and the additional operation strength of the additional operation unit 400, respectively, in the mobile terminal case according to the embodiment of the present invention.

Meanwhile, the foreign substance removing device of the mobile terminal case according to the embodiment of the present invention performs a charge removing operation on the mobile terminal case after completing the buffing operation and then performs the blowing operation to completely remove the foreign substance remaining on the surface of the mobile terminal case It is possible to do.

The mobile terminal case may be made of a magnesium material. In this case, the mobile terminal case and the foreign substance after the buffing operation, which is a polishing process, have a very high electrostatic property. Therefore, the foreign substance removing apparatus of the mobile terminal case according to the embodiment of the present invention will have a very excellent effect for removing the foreign substance having high electrostatic characteristics.

In addition, the above-described operations of the foreign substance removing apparatus of the mobile terminal case according to the embodiment of the present invention are all automated. Therefore, foreign matter can be removed from a large amount of mobile terminal cases at a low cost, and mobile terminal cases with foreign substances can be guaranteed to be substantially uniformly removed from each other.

Meanwhile, as described above, the main operation strength of the main operation unit 300 and the additional operation strength of the additional operation unit 400 are each controllable.

Particularly, the additional operation strength of the additional operation unit 400 can be controlled according to a state value discharged through the exhaust unit 330 corresponding to the main operation unit 300. Here, the status value means, for example, the kind and amount of the foreign substance. That is, it is possible to control the static electricity operation intensity and the air flow operation intensity of the additional operation unit 400 according to the kind and amount of the foreign matter discharged through the exhaust part 330.

In this case, for example, the following operations are possible.

First, the foreign matter removing device of the mobile terminal case performs a charge removing operation and a blowing operation on the mobile terminal case through the main operation unit 300. By this operation, the mobile terminal case and foreign matters are separated. After the foreign matter is separated, the exhaust part 330 discharges the separated foreign material to the outside. Then, in this process, the type of the foreign matter discharged (for example, the kind depending on the charge rate of the charge) is detected or whether or not the amount of the foreign matter exceeds the reference value is detected. Then, it is possible to adjust the operation strength of the additional operation unit 400 in accordance with the detection result.

If the type of the foreign substance is a substance that is difficult to neutralize static electricity or the amount of the foreign substance exceeds a predetermined standard value, the operation unit 400 can increase the operation strength, and conversely, the operation strength can be lowered.

In other words, the foreign substance removing apparatus of the mobile terminal case according to the embodiment of the present invention is capable of reducing foreign matter, which is discarded without any meaning, to information for controlling the additional operation unit 400, 400) can operate more smartly according to more information.

In a similar operation, it is possible to minimize power consumption by deactivating the additional operation unit 400 when the amount of foreign matter discharged from the exhaust part 330 is less than a reference value.

The embodiments and the accompanying drawings described here are only illustrative of some of the technical ideas included in the present invention. Therefore, it is to be understood that the embodiments disclosed herein are not for purposes of limiting the technical idea of the present invention, but are intended to be illustrative, and thus the scope of the technical idea of the present invention is not limited by these embodiments.
