FIG. 3 is a cross-sectional view of the pressing structure according to an embodiment of the present invention, FIG. 4 is a schematic conceptual view showing a pressing structure in contact with a panel in order to explain contact and release of the pressing structure with respect to the panel according to one embodiment of the present invention, and FIG. 4 is a perspective view 5 is a schematic cross-sectional view cut along the line AA in Fig. 4, Fig. 6 is an enlarged view of Fig. 5 (B), and Fig. 7 is a cross- To explain the contact and release of the pressing structure with respect to the panel according to an embodiment of the present invention having the insertion port according to the present invention, And Figure 8 is a schematic perspective view of the pressing jig and the body portion mounting portion having an insertion hole in accordance with another embodiment.

1 and 3 together, the main pressing structure contacts the pad portion formed on the lower surface of the work table 9 and the panel 7 on which the panel 7 is seated, and performs inspection on the panel 7 The present invention can be applied to an auto-probe inspection apparatus including a probe unit 8.

Referring to FIG. 3, the panel 7 may be an organic electroluminescent display type panel in which a pad portion 72 is formed on the front surface. In this case, the panel 7 can be seated on the work table 9 with its front surface facing downward, as shown in Fig. For reference, in the present application, the lower surface of the panel 7 means the front surface of the panel 7 facing downward, and the upper surface of the panel 7 means the rear surface of the panel 7 facing upward.

Referring to Figs. 1 and 2, the main pressing structure includes a pressing jig 11.

3, the pressing jig 11 is in contact with the upper edge 71 of the panel 7 to limit the upward movement of the panel 7.

Illustratively, the upper surface frame 71 may refer to the opposite surface (upper surface) portion of the lower surface portion of the panel 7 where the pad portion 72 is formed, as shown in Fig.

In general, the panel 7 is seated on the work table 9 so that the pad portion 72 faces downward. The probe unit 8 is positioned below the pad portion 72 of the panel 7 mounted on the work table 9 so as to be able to contact the pad portion 72 facing downward, So that the panel 7 is inspected in contact with the pad portion 72.

However, when the probe unit 8 is moved upward and comes into contact with the pad portion 722, a predetermined external force acts on the panel 7 in the upward direction. The panel 7 can be moved upward by an external force, for example, it can be lifted upwards. 3, the pressing jig 11 is in contact with the upper edge 71 of the panel 7 before the probe unit 8 and the pad 72 come into contact with each other, The upward movement of the mobile terminal can be restricted.

3, the main pressing structure has an upper surface frame portion 71 of the panel 7 and a pressing jig (not shown) on the upper surface frame 71 of the panel 7 when the pressing jig 11 is in contact with the upper surface frame portion 71 of the panel 7 And a gas suction part 5 for providing an adsorption force between the gas suction part 11 and the gas suction part 5.

The position of the panel 7 can be fixed by the attraction force between the upper edge portion 71 of the panel 7 and the pressing jig 11. [ In other words, the movement of the panel 7 in the horizontal direction can be restricted. Thus, contact failure between the probe unit 8 and the pad portion 72 can be prevented. Conventionally, the panel 7 seated on the work table 9 is moved in the horizontal direction, and an error may occur in the contact between the probe unit 8 and the pad portion 72. However, according to the present pressing structure, it is possible to restrict the movement of the panel 7, which is seated on the work table 9, in the horizontal direction. As a result, a contact error between the probe unit 8 and the pad portion 72 is prevented .

3 and 4, the pressing jig 11 extends upward from the pressing portion 112 and the pressing portion 112 which are in contact with the upper surface frame portion 71 of the panel 7 And a support portion 113 mounted on the body mounting portion 12, which will be described later. Illustratively, as shown in Figs. 3 and 4, the support portion 113 can be bent and extended from the pushing portion 112 in the upward direction. Alternatively, although not shown in the drawings, the supporting portion 113 may be formed to extend upward from the pressing portion 112 without being bent.

5 and 6, the pressing portion 112 may be formed with a low pressure forming portion 11223 which is depressed in the upward direction on its lower surface. Also, referring to FIG. 6, the gas suction unit 5 may make the inside of the low-pressure forming portion 11223 a low-pressure state.

Illustratively, the gas suction unit 5 can suck the gas inside the low-pressure forming portion 11223 to make the inside of the low-pressure forming portion 11223 a low-pressure state. Thus, an attraction force can be formed between the pressing portion 112 and the upper surface frame portion 71 of the panel 7.

6, the pressing portion 112 may include an insertion port 11221 through which the end of the gas suction unit 5 is inserted. Referring to FIG. 6, the cross-sectional area of the front end of the insertion port 11221 may decrease toward the front. 6, the pressing portion 112 may be provided with a communication port 11222 for communicating the insertion port 11221 and the low-pressure forming portion 11223 with each other.

6, the communication port 11222 is formed in a direction perpendicular to the low-pressure forming portion 11223, and the insertion port 11221 is formed in the rear side from the communication port 11222. [ As shown in FIG. 5 and 6, the end of the gas suction unit 5 can be inserted into the pressing portion 112 from the rear side of the pressing portion 112 forward.

4 and 5, the gas suction unit 5 extends from the upper side of the mounting block 121 to the inside of the mounting block 121, 112 from the rear side thereof. As a result, the gas suction unit 5 can be prevented from unnecessarily consuming the space, resulting in aesthetic effect that looks neat.

According to another embodiment of the insertion port 11221, as shown in Fig. 7, the communication port 11222 may extend upward from the low-pressure forming portion 11223. The insertion port 11221 may extend upward from the communication port 11222. [ 7 and 8, the end of the gas suction unit 5 can be inserted into the pressing portion 112 from the upper side of the pressing portion 112 downward.

6 and 7, the upper portion of the end 51 inserted into the insertion opening 11221 of the low-pressure forming portion 5 is provided with a support protrusion 52 supported by the presser portion 112 along the periphery thereof. Can be formed. 6, according to one embodiment of the insertion port 11221, the support jaw 52 may be supported on the back surface of the presser portion 112. As shown in Fig. 7, according to another embodiment of the insertion port 11221, the support jaw 52 may be supported on the upper surface of the pressing portion 112. [

4 and 8, one or more holes 1121 may be formed in the pressing portion 112 in the vertical direction so that light emitted by the panel 7 passes through the pressing portion 112. [

Specifically, when the panel 7 contacts the pad unit 72 of the panel 7 and the probe unit 8 emits light, the diverged light can pass through the hole 1121. The result of the lighting inspection of the panel 7 is confirmed according to the presence or absence of light emitted to the upper side of the hole 1121 through the hole 1121 when the pad unit 72 and the probe unit 8 are in contact with each other .

The hole 1121 may have a circular cross section. Alternatively, as shown in Figs. 4 and 8, the cross section of the hole 1121 may be in the form of an elongated hole.

3 to 5 and 8, the pressing jig 11 may include a horizontal adjusting unit 13 for adjusting the horizontal position of the jig block 111. As shown in FIG.

The horizontal direction of the jig block 111 may mean a state in which the lower surface of the jig block 111 is not tilted to one side and is flat.

As described above, if the jig block 111 for pressing the panel 7 is not leveled, the panel 7 may be damaged. The conventional auto-probe inspection apparatus does not include a structure for adjusting the horizontal level of the lower surface of the pushing jig in contact with the upper edge of the panel, thereby causing damage to the panel.

However, as described above, the pushing structure 11 is divided into the plurality of jig blocks 111, and the jig blocks 111 (see FIG. 1), which are in contact with the upper edge portion 71 of the panel 7, When the lower surface of the jig block 111 is not in a horizontal state, the jig block 111 can be set in a horizontal state through the horizontal adjustment unit 13. [

3 and 4, the horizontal adjustment unit 13 includes a reference block 131, a reference block 131, and a support portion 113 located on the upper side of the jig block 111, And a plurality of horizontal adjustment members 132 disposed at the same time. The horizontal adjustment members 132 may be spaced apart from each other as shown in FIG.

The portion of the support portion 113 where the horizontal adjustment member 132 is rotated can be relatively moved up and down with respect to the reference block 131 when the horizontal adjustment member 132 rotates.

4, when the jig block 111 is biased in one direction, the jig block 111 can be moved up and down by rotating the horizontal adjustment member 132 located at the deflected portion . Or when the jig block 111 is biased in one direction, the jig block 111 can be moved downward in the vertical direction by rotating the horizontal adjusting member 132 located at the deflected portion. Accordingly, the horizontal state of the jig block 111 can be set.

The horizontal adjustment unit 13 may also include an idling prevention bolt 133 for preventing the horizontal adjustment member 132 from idling relative to the reference block 131, as shown in Fig.

8, the pushing jig 11 may include a fastening bolt 116 for fastening the jig block 111 to the body mount 12. As shown in FIG. Referring to FIG. 8, the fastening bolts 116 are arranged to penetrate the support portion 113 and the body mounting portion 133 in the horizontal direction at the same time, thereby fixing the jig block 111 to the body mounting portion 12.

According to the fastening bolt 116, the jig block 111 can be prevented from moving in the vertical direction even if the horizontal adjusting member 132 is rotated.

That is, when the horizontal adjustment member 132 is required to be rotated for horizontal adjustment of the jig block 111, the fastening bolt 116 is released to make the jig block 111 movable in the vertical direction The leveling member 132 may be rotated to adjust the level of the jig block 111. [ When the horizontal adjustment of the jig block 111 is completed, the fastening bolt 116 can be fastened to maintain the state of the horizontally adjusted jig block 111.

The contact or release of the pushing jig 11 with respect to the upper edge 71 of the panel 7 is realized by the body portions 15a, 15b, 15c and 15d.

The body portions 15a, 15b, 15c and 15d will be described more specifically.

The main pressing structure includes body portions 15a, 15b, 15c and 15d with reference to Figs.

The body portions 15a, 15b, 15c and 15d move the pressing jig 11 in the vertical direction.

Accordingly, when the body portions 15a, 15b, 15c, 15d lower the pushing jig portion 11 in the downward direction, the pushing jig portion 11 can be brought into contact with the upper surface rim portion 71. [ When the body portions 15a, 15b, 15c and 15d lift the pushing jig 11 up and down, the pushing jig 11 can be released from the upper edge 71 of the body.

Referring to FIGS. 1 and 2, at least two body portions may be provided. Further, each of the two or more body portions may be provided along the circumference of the work table 9. Each of the two or more body parts may have a pressing jig 11.

Illustratively, as shown in Figs. 1 and 2, the body portions 15a, 15b, 15c and 15d may be provided in four. 1, the four body portions 15a, 15b, 15c and 15d have a first body portion 15a, a first body portion 15a and a second body portion 15b provided on one side of the work table 9, A third body part 15c and a third body part 15b which are adjacent to the second body part 15b and the second body part 15b and are disposed opposite to the first body part 15a, And a fourth body portion 15d adjacent to the second body portion 15b and facing the second body portion 15b.

Further, as will be described later in detail, the first body part 15a and the third body part 15c may be moved in directions facing each other or in directions away from each other. Further, the second body part 15b and the fourth body part 15d may be moved in directions facing each other or in directions away from each other.

1, each of the first to fourth body portions 15a, 15b, 15c, and 15d may be provided with a pressing jig 11. As shown in FIG.

The pushing jig 11 and the body portions 15a, 15b, 15c and 15d are connected by the body mounting portion 12 with reference to Figs.

1 and 3, the pressing jig 11, the body mounting portion 12 and the body portions 15a, 15b, 15c and 15d are located on the upper side of the probe unit 8. [ Interference between the driving radius of the pressing jig portion 11 and the driving radius of the probe unit 8 does not occur and durability can be ensured even when the pressing jig portion 11 and the probe unit 8 are driven.

According to the conventional auto-probe inspection apparatus, since the probe unit is inserted into the window of the pushing jig and driven, the driving radius of the probe unit and the driving radius of the pushing jig are overlapped with each other, and a window is formed in the pushing jig, The durability of the pressing jig could not be secured.

However, according to the main pressing structure, the pressing jig 11, the body mounting portion 12 and the body portions 15a, 15b, 15c and 15d are located on the upper side of the probe unit 8, And the probe unit 8 can be independently formed with respect to each other, and it is not necessary to form a window in the pressing jig 11, so that the durability of the pressing jig 11 can be ensured.

Referring to FIGS. 1 and 2, the pressing jig 11 may be divided into a plurality of jig blocks 111.

As a result, it is possible to prevent the panel 7 from being damaged when the panel 7 is inspected. Specifically, in the conventional auto-probe inspection apparatus, when the panel area is large, the length of the pressing jig is increased corresponding to the area of the panel. However, when the length of the pressing jig is increased, the pressing jig which was initially in a horizontal state is gradually tilted in one direction. When the pressing jig tilted in one direction is brought into contact with the upper edge of the panel, One part was given more power than the other part, and the part with greater power could be damaged.

However, according to the main pressing structure, the pressing jig 11, which is in contact with the upper surface frame portion 71 of the panel 7, is divided into a plurality of jig blocks 111, The length of the jig block 111 is not increased but the number of the jig blocks 111 each having an appropriate length is increased so that the problem that the level of the lower surface of the pressing jig portion 11 is not maintained Can be prevented.

As shown in Figs. 1 and 2, the length of the jig block 111 may vary. 2, the jig block 111 and the panel 7 mounted on the first body part 15a located at 12 o'clock centered on the panel 7 are disposed at the 6 o'clock position The length of the jig block 111 mounted on the third body part 15c positioned may be different. The length of the jig block 111 can be determined in accordance with the positional point of the jig block 111 with respect to the panel 7 and the force acting on the panel 7 by the jig block 111 and the like.

1 and 2, the plurality of jig blocks 111 may be disposed at predetermined intervals with respect to one another.

More specifically, referring to the gap between the jig blocks 111 mounted on the first body portion 15a of FIG. 2, the plurality of jig blocks 111 are arranged such that a plurality of jig blocks 111 are connected and operated They can be provided close to each other so as to exert the same effect.

Alternatively, the plurality of jig blocks 111 may be formed so that a plurality of jig blocks 111 can independently exhibit an effect, such as an interval between the jig blocks 111 mounted on the third body portion 15c of Fig. 2 , And may be spaced apart from each other at a predetermined interval. The interval between the jig blocks 111 may be determined according to the position of the jig block 111 with respect to the panel 7, the magnitude of the force acting on the panel 7 by the jig block 111, and the like.

1 and 2, the body mounting portion 12 may be divided into a plurality of mounting blocks 121. In this case,

As a result, the durability of the body mounting portion 12 can be secured. If the size of the body mount 12 is increased, its durability can be weakened. However, the main pressing structure secures durability by dividing the body mounting portion 12 into a plurality of mounting blocks 121.

The body portions 15a, 15b, 15c and 15d are connected to the panel 7 by means of a driving portion (not shown) in the inward direction (direction toward the panel 7 in Fig. 1 and Fig. 2) See FIGS. 1 and 2, in a direction away from the panel 7).

1 and 2, the first body part 15a and the third body part 15c are moved in directions facing each other or apart from each other, and the second body part 15b and the third body part 15c Each of the four body portions 15d may be moved in a direction toward or away from each other.

Thus, the body portions 15a, 15b, 15c and 15d are moved to the side of the panel 7 before or after the upward and downward driving of the pressing jig 11, And can be moved in a direction away from each other.

Hereinafter, an autoprobe inspection apparatus (hereinafter referred to as "the present autoprobe inspection apparatus") including a pressing structure according to an embodiment of the present invention will be described. It should be noted, however, that the same reference numerals are used for the same or similar components as those of the foregoing embodiment, and a duplicate description will be simplified or omitted.

FIG. 9 is a schematic perspective view of a work table and a stopper according to one embodiment of the present application, FIG. 10 is a schematic side view of a work table and a stopper shown in FIG. 9, and FIG. 11 is a cross- FIG. 12 is a schematic conceptual view showing an enlarged view of a part of a work table for explaining an air blower according to an embodiment of the present invention; FIG.

This automatic probe inspection apparatus includes a work table 9, referring to Fig. The panel (7) is seated on the work table (9). The panel 7 is seated on the work table 9 with the front surface on which the pad portion 72 is formed facing downward.

The present autocube inspection apparatus includes a probe unit 8. The probe unit 8 contacts the pad portion 72 of the panel 7 which is seated on the work table 9 and performs inspection for the panel 7. [ This auto-probe inspection apparatus includes a plurality of such probe units 8.

In addition, the present autoprobe inspection apparatus includes a pressing structure according to an embodiment of the present invention. This makes it possible to ensure the durability of the present autoclave inspection apparatus, and to perform the inspection on the panel 7 while minimizing damage to the panel 7. [

The automatic probe inspection apparatus may further include a table gas suction unit (not shown) for applying a suction force between the panel 7 placed on the work table 9 and the work table 9. Illustratively, the table gas sucking portion is provided on the work table 9, and an attraction force can be formed from the upper surface of the work table 9 downward. Accordingly, the position of the panel 7 seated on the work table 9 can be fixed.

9 and 10, the automatic probe inspection apparatus may include a stopper 6 for restricting the movement of the panel 7, which is seated on the work table 9, in the horizontal direction.

As shown in Fig. 9, the stopper 6 can be disposed along the circumference of the work table 6. 10, the upper surface of the stopper 6 may be positioned higher than the upper surface of the work table 9 by a predetermined length. The predetermined length may be a value equal to or greater than the thickness of the panel 7. [ This is because the upper surface of the stopper 6 is positioned higher than the upper surface of the panel 7 loaded on the work table 9 so that the movement of the panel 7 in the horizontal direction is restricted by the stopper 6 It is for this reason.

Further, the stopper 6 can be moved inward or outward relative to the work table 9. Specifically, the stopper 6 can be moved inward with respect to the work table 9 so as to contact the panel 7. Alternatively, it may be moved outward with respect to the work table 9 to release the contact with the panel 7.

The movement of the stopper 6 can be realized by a linear driving unit. Illustratively, the linear driving unit may include a rail provided along the movement path of the stopper 6 on the lower side of the stopper 6, and a guide unit mounted on the lower surface of the stopper 6 and movable along the rail. With this linear drive unit, the guide unit is moved along the rails, so that the stopper 6 can be moved inward or outward with respect to the work table 9. For reference, the guide unit can be moved along the rails by pneumatic or hydraulic pressure.

The stopper 6 can be driven in this manner. Illustratively, the stopper 6 can move inward relative to the work table 9 before the pressing jig 11 contacts the rear edge 71 of the panel 7. Thus, the panel 7 can be aligned in the horizontal direction before the pressing jig 11 contacts the rear edge portion 71. [

The stopper 6 can be moved in the outward direction with respect to the work table 9 after the above-described movement in the inward direction is completed. The stopper 6 can be released from contact with the panel 7 after the alignment of the panel 7 is completed.

The movement of the stopper 6 in the outward direction relative to the work table 9 can be performed before or after the contact with the rear edge portion 71 of the pressing jig 11. [

If the movement of the stopper 6 in the outward direction relative to the work table 9 is performed prior to the contact with the rear edge 71 of the pressing jig 11, The panel 7 can be brought into contact with the panel 7 after it has been in contact with the rear edge 71 of the panel 7 and then moved inward. The stopper 6 reattached to the panel 7 through re-movement in the inward direction can prevent the positional shift of the panel 7 in the horizontal direction.

As described above, according to the present auto-probe inspection apparatus, the panel 7 can be aligned by the stopper 7. The upward movement of the panel 7 can be restricted by the pressing jig 11 when the probe unit 8 is inspected. Further, the movement of the panel 7 in the horizontal direction by the stopper 6 can be restricted. Further, the panel 7 can be fixed on the work table 9 by the table gas suction portion.

The stopper 6 moves inward relative to the work table 9 after the pressing jig 11 contacts the rear edge portion 71 of the panel 7 to move the panel 7 in the inward direction with respect to the work table 9, This is to prevent damage to the panel 71 that may occur when the pressing jig 11 and the stopper 6 come into contact with the panel 71 at the same time.

If the pressing jig 11 and the stopper 6 come into contact with the panel 71 at the same time, an external force acts on the panel 71 in various directions within a short time. As a result, the panel 71 may be damaged. This automatic probe inspection apparatus can prevent the panel 7 from being damaged by making the contact between the panel 7 and the pressing jig 11 and the contact between the panel 7 and the stopper 6 sequentially .

11, the automatic probe inspection apparatus includes a stopper 6 and a stopper 6 interposed between the workpiece table 9 and the stopper 6 so that the interval between the stopper 6 and the circumferential surface of the workpiece table 9 is kept constant. And a gap holding portion 5 for holding the gap.

11, the gap holding portion 5 may be formed so as to project toward the work table 9 from the surface of the stopper 6 facing the work table 9. That is, the gap holding portion 5 can be formed integrally with the stopper 6. Accordingly, the gap holding portion 5 and the stopper 6 can be closely interlocked and driven.

12, the autoclave inspection apparatus may include an air blower 4 provided below the work table 9 to inject gas so as to remove particles on the probe unit 8.

The probe unit 8 may refer to a portion of the probe unit 8 that is in contact with the pad portion 72 of the panel 7. In addition, the particles may mean various foreign substances. In addition, the air blower 4 can remove particles on the probe unit 8 by spraying gas before the probe unit 8 comes into contact with the pad portion 72. Thus, the accuracy of the inspection can be improved.

The autoclave inspection apparatus may include a base portion (not shown). The above-described work table 9, the probe unit 8 and the pressing structure 1 can be mounted on the base portion.

The panel inspection method of organic electroluminescence display type includes a step in which the pressing jig 11 and the probe unit 8 are moved inward to approach the panel 7 between steps S100 and S200 . The pushing jig 11 and the probe unit 8 can be brought close to the panel 7 so as to be able to contact the panel 7 before step S200.

The panel inspection method of the organic electroluminescence display type includes a step S300 in which the rear edge 71 of the panel 7 is fixed in position by the attraction force of the gas suction unit 5. A suction force is generated between the rear edge 71 of the panel 7 and the pressing jig 11 by the gas suction unit 5 so that the position of the panel 7 can be fixed.

The method of inspecting a panel of the organic electroluminescence display type according to the present invention is characterized in that the step S200 of contacting the pressing jig 11 with the rear edge 71 and the rear edge 71 of the panel 7, (S300) in which the position is fixed by the attraction force of the table gas suction unit (5), the supply of the attraction force of the table gas suction unit may be interrupted.

In addition, the panel inspection method of the organic electroluminescent display type includes a step (S400) in which the probe unit 8 is brought into contact with the pad portion 72 to perform inspection.

In step S400, the probe unit 8 can be moved up and down in the upward direction so as to be in contact with the pad part 91. [

The panel inspection method of the organic electroluminescent display type is characterized in that the air blower 4 is moved to the probe unit 8 before the probe unit 8 is contacted to the pad unit 72 to perform inspection (S400) Spraying the gas so that particles on the surface are removed.

The panel inspection method of the organic electroluminescence display type includes a step S500 of the probe unit 8 to be released from the pad portion 72 (S500).

After the inspection is performed, the probe unit 8 can be released from the pad portion 72.

In step S500, the probe unit 8 can be moved downward in the Z-axis direction to be released from the pad portion 72. [

In addition, the panel inspection method of the organic electroluminescence display type includes a step (S600) of stopping the adsorption of the gas suction unit. As a result, the suction between the rear edge portion 71 of the panel 7 and the pressing jig 11 can be released.

The panel inspection method of the organic electroluminescence display type includes a step S700 in which the pressing jig 11 is released from the rear edge 71.

In step S700, the pushing jig 11 can be moved up and down in the upward direction to be released from the rear edge 71.

Further, the panel inspection method of the organic electroluminescence display type may include a step S800 in which the panel 7 is unloaded from the work table 9 (S800).

The panel inspection method of organic electroluminescence display type may include a step in which the probe unit 8 and the pressing jig 11 are moved outward from the panel 7 between steps S500 and S800 .

Alternatively, the panel inspection method of the organic electroluminescence display type may include a step in which the probe unit 8 is moved outward from the panel 7 after step S500, and after the step S700, the pushing jig 11 May be moved in an outward direction away from the panel 7.
