Referring to fig. 1 to 4, the display module DM may include a display panel DP, a first connector C1, and a second connector C2. In one embodiment, the display panel DP may include a display portion and a digitizer. The display part may display an image, and the digitizer senses a signal transmitted by an external input.

The first connector C1 may protrude toward one side of the display module DM. For example, the first connector C1 may protrude from the display panel DP by a length in the first direction D1. The first connector C1 may be electrically connected with the display panel DP. For example, the first connector C1 may be connected to the display portion in the display panel DP.

For example, the first connector C1 may be connected to the digitizer in the display panel DP. That is, the second connector C2 may mean a digitizer connector. A signal may be applied to the digitizer through the second connector C2 to perform a test therefor. However, without being limited thereto, the second connector C2 may mean other kinds of connectors.

The display module contacting apparatus 1000 may include a table 100, a first inspection socket 200, a second inspection socket 300, an alignment jig 500, an alignment apparatus 400, and a clamping member 600. The display module contacting apparatus 1000 may perform a contacting process for the display module DM. The contact process may mean a process of electrically connecting the display module DM and the first and

second inspection sockets

200 and 300 before performing various inspections on the performance of the display module DM. More specifically, the contact process may mean a process of electrically connecting the first and second connectors C1 and C2 of the display module DM with the first and

second inspection sockets

200 and 300.

The table 100 may provide a space in which the display module DM is disposed. That is, the contact process of the display module DM may be performed on the table 100. In an embodiment, the table 100 may include a table main body 110, a seating portion 120, and a disposition hole 130. The table main body 110 may support the seating portion 120. The disposing part 120 may provide a space in which the display module DM is disposed. In other words, the display module DM may be disposed on the mounting portion 120 when the contact process is performed. In one embodiment, the seating portion 120 may be in the form of protruding from the table main body 110 in the third direction D3. The area of the disposing part 120 may be similar to or larger than the area of the display module DM. The disposition hole 130 may be in the form of a recess from the upper surface of the table main body 110 in a direction opposite to the third direction D3 by a certain depth. In one embodiment, a second inspection socket 300 may be disposed in the disposition hole 130.

The first checking socket 200 may be electrically connected with the first connector C1 of the display module DM. Specifically, the first check socket 200 may apply an external check signal to the first connector C1. In one embodiment, the first inspection socket 200 may be electrically connected to wiring in the table 100. Therefore, if the table 100 receives an inspection signal from the outside, the inspection signal may be transmitted to the first connector C1 through the first inspection socket 200. The first checking receptacle 200 may be previously disposed on the table 100 before the display module DM is disposed on the table 100.

The second checking socket 300 may be electrically connected with the second connector C2 of the display module DM. Specifically, the second check socket 300 may apply an external check signal to the second connector C2. In one embodiment, the second inspection socket 300 may be electrically connected to wiring in the table 100. Therefore, if the work table 100 receives an inspection signal from the outside, the inspection signal may be transmitted to the second connector C2 through the second inspection socket 300. In one embodiment, the second inspection socket 300 may be disposed in the disposition hole 130. For example, the second check socket 300 may be previously disposed in the disposition hole 130 before the display module DM is disposed on the table 100.

Fig. 5 is a perspective view illustrating a second inspection socket included in the display module set contact device of fig. 1, and fig. 6 is a sectional view taken along line I-I' of fig. 5.

Hereinafter, a specific shape and function of the second inspection socket 300 will be described in more detail with reference to fig. 1 to 6.

The second inspection socket 300 may include a socket body 310, inspection pins 320, a base plate 330, and a protection wall 340.

The socket body 310 may support the second connector C2. In one embodiment, the socket body 310 may include a protrusion 312 and a recess 314. The projection 312 may directly interface with the second connector C2. For example, the second connector C2 may be disposed on the protrusion 312 of the socket body 310. The upper level of the projection 312 may be the same as the upper level of the protection wall 340. Accordingly, in the coupling process of the alignment jig 500 and the second inspection socket 300, which will be described later, the moving path of the alignment jig 500 can be more smoothly ensured. The recess 314 may be adjacent to the projection 312. For example, the recess 314 may be located between the projection 312 and the protective wall 340. The recess 314 may have a smaller thickness than the protrusion 312. In an embodiment, the recess 314 may be formed by implementing an engraved pattern in the socket body 310.

The level of the upper face of the recess 314 may be lower than the level of the upper face of the projection 312 and the level of the upper face of the protection wall 340. Thus, the second inspection socket 300 may have the insertion space IS constituted by the steps between the upper face of the recess 314 and the upper face of the projection 312 and the upper face of the protection wall 340. The insertion portion of the alignment jig 500 may be inserted into the insertion space IS during the coupling of the alignment jig 500 and the second inspection socket 300, which will be described later. The insertion space IS may further improve the coupling accuracy of the alignment jig 500 and the second inspection socket 300 by preventing a phenomenon in which the alignment jig 500 IS shaken or misaligned during the coupling with the second inspection socket 300. The details of the coupling process of the alignment jig 500 and the second inspection socket 300 will be described in more detail with reference to fig. 9 and 10.

The inspection pin 320 may be disposed in the socket body 310. Specifically, the inspection pin 320 may be disposed in the protrusion 312 of the socket body 310. In one embodiment, an inspection groove IH may be formed on the upper surface of the protrusion 312 of the socket main body 310. The inspection groove IH may expose the inspection pin 320. In one embodiment, as the alignment jig 500 and the second inspection socket 300 are coupled, the inspection pin 320 may be protruded through the inspection groove IH to be coupled with the second connector C2. For example, the inspection pin 320 may contact the lower face of the second connector C2. In an embodiment, the inspection pin 320 may be electrically connected with the second connector C2. Thus, the inspection pin 320 can function as a medium for electrically connecting the second connector C2 to another structure.

The base plate 330 may support the socket main body 310. The base plate 330 may be inserted into the disposition hole 130 of the table 100. The area of the base plate 330 may be substantially the same as or similar to the area of the configuration holes 130 or smaller than the area of the configuration holes 130.

The protective wall 340 may surround the socket body 310. The protective wall 340 may protect the socket body 310 from external impact or the like. As described above, the upper level of the protection wall 340 may be the same as the upper level of the projection 312 of the socket main body 310. In addition, the upper surface of the protection wall 340 may have a higher level than the upper surface of the recess 314 of the socket body 310.

Again, referring to fig. 1 to 4, the alignment apparatus 400 may include a coupling member 410, an electromagnet 420, a moving member 430, a support member 440, and a vacuum tube 450. The alignment apparatus 400 may move the alignment jig 500. Thus, the alignment apparatus 400 may align the second connector C2 by controlling the position of the alignment jig 500. Specifically, the alignment apparatus 400 may align the second connector C2 on the second inspection socket 300 by controlling the position of the alignment jig 500. In addition, the alignment device 400 may attach the second connector C2 to the second inspection socket 300. Hereinafter, each of the coupling part 410, the electromagnet 420, the moving part 430, the supporting part 440, and the vacuum tube 450 will be described in more detail.

The combining part 410 may be selectively combined with the alignment jig 500. That is, the alignment jig 500 may be coupled to the coupling member 410 or separated from the coupling member 410, as necessary. For example, an alignment jig arrangement space that can be coupled to the alignment jig 500 may be formed below the coupling member 410. At this time, the alignment jig 500 may be coupled with the coupling member 410 by being disposed in the alignment jig disposition space. In an embodiment, the coupling member 410 may have a rod shape extending a certain length in the first direction D1, but is not necessarily limited thereto.

The electromagnet 420 may be in the form of being coupled to the coupling member 410. In an embodiment, the electromagnet 420 may be exposed through an upper face of the coupling member 410. However, the electromagnet 420 may be buried in the coupling member 410. The electromagnet 420 may include a substance that is magnetized if a current flows. In one embodiment, the electromagnet 420 may be connected to the power supply E. The electromagnet 420 may be magnetized by receiving power from the power supply E. That is, the electromagnet 420 may have the property of a magnet through the power supply part E. When the electromagnet 420 receives power from the power supply E to have the property of a magnet, the electromagnet 420 and the first clamp body 510 may be magnetically coupled to each other. That is, the electromagnet 420 may provide an attractive force to combine the coupling member 410 and the alignment jig 500. Accordingly, the alignment jig 500 may be coupled with the coupling member 410. In contrast, when the power supply of the power supply portion E is interrupted, the electromagnet 420 may lose the property of the magnet. Thereby, the attractive force of the electromagnet 420 combining the coupling member 410 and the alignment jig 500 may disappear. Accordingly, at this time, the alignment jig 500 may be separated from the coupling member 410. That is, the alignment jig 500 may be coupled to the coupling member 410 or separated from the coupling member 410 by the electromagnet 420, as necessary.

The moving member 430 may move the combining member 410 in parallel as well as in rotation. For example, the combining part 410 may be horizontally moved in the first direction D1 and the second direction D2 by the moving part 430. In addition, the combining member 410 may be vertically moved in the third direction D3 by the moving member 430. In addition, the coupling member 410 may be rotationally moved around an axis aligned with the third direction D3 by the moving member 430. In an embodiment, the moving member 430 may have the form of a robot arm. However, the form of the moving member 430 is not necessarily limited to the form of a robot arm, and the moving member 430 may be in the form of including a plurality of moving parts including a work for driving. In this case, the plurality of moving parts may include actuators such as linear electric motors, hydraulic motors, and rotary motors.

The supporting member 440 may be disposed at one side of the coupling member 410. For example, the supporting member 440 may be combined with the combining member 410 to protrude a certain length in the first direction D1 from one side of the combining member 410. Thus, the support member 440 may overlap a portion of the alignment jig 500, which does not overlap the coupling member 410, in a plane. Accordingly, when the alignment apparatus 400 applies a force to the alignment jig 500, the support member 440 may minimize or prevent deformation of the alignment jig 500 by supporting a portion of the alignment jig 500 that does not overlap with the coupling member 410. For example, to couple the alignment jig 500 to the second inspection socket 300, when the alignment apparatus 400 applies a force to the alignment jig 500 in a direction opposite to the third direction D3, the support member 440 may counteract the force of the corresponding portion moving in the third direction D3 by supporting the portion of the alignment jig 500 that does not overlap with the coupling member 410. Thereby, deformation of the alignment jig 500 may be minimized or prevented.

The vacuum tube 450 may be coupled to the coupling member 410. The vacuum pipe 450 may be connected to a vacuum pump P. The vacuum pipe 450 may transmit vacuum pressure provided by the vacuum pump P to the bonding part 410 and the alignment jig 500. Thereby, the alignment jig 500 can suck the second connector C2. For this, it will be described in more detail below with reference to fig. 14 to 17.

The alignment jig 500 may be selectively combined with the alignment device 400. Specifically, the alignment jig 500 may be selectively coupled with the coupling member 410 of the alignment device 400. That is, the alignment jig 500 may be coupled to the coupling member 410 or separated from the coupling member 410, as necessary. When the alignment jig 500 is coupled to the coupling member 410 of the alignment apparatus 400, the position of the alignment jig 500 may be controlled as the coupling member 410 is moved by the moving member 430 of the alignment apparatus 400.

The alignment jig 500 may be selectively combined with the second inspection socket 300. For example, as the position of the alignment jig 500 is controlled by the alignment device 400, the alignment jig 500 is coupled to the second inspection socket 300 or separated from the second inspection socket 300. In addition, the alignment jig 500 may attach the second connector C2 to the second inspection socket 300. For example, the alignment jig 500 may be combined with the second inspection socket 300 after aligning the position of the second connector C2 on the second inspection socket 300, thereby attaching the second connector C2 to the second inspection socket 300. Details of the coupling process of the alignment jig 500 and the second inspection socket 300 will be described in more detail below with reference to fig. 9 and 10.

In an embodiment, the alignment jig 500 may be fixed on the second inspection socket 300 after being combined with the second inspection socket 300. For example, the alignment jig 500 may be clamped on the second inspection socket 300 by the clamp 600. Specifically, even after the alignment device 400 is separated from the alignment jig 500, the alignment jig 500 may be fixed on the second inspection socket 300 by the clamp 600. Thereby, the alignment jig 500 can fix the second connector C2 to the second inspection socket 300. Accordingly, even in the performance inspection process of the display module DM performed after the contact process, the state in which the alignment jig 500, the second connector C2, and the second inspection socket 300 are fixed by the clamping member 600 can be maintained.

Fig. 7 is a perspective view illustrating an alignment jig included in the display module set contact device of fig. 1, and fig. 8 is a right side view illustrating the alignment jig of fig. 7.

Hereinafter, a specific shape and function of the alignment jig 500 will be described in more detail with reference to fig. 1 to 4, 7, and 8.

The alignment jig 500 may include a first jig body 510, a second jig body 520, and an insertion part 530.

The first jig body 510 may be disposed in the alignment jig disposition space below the coupling member 410. Specifically, as the alignment jig 500 is coupled to the coupling part 410 of the alignment device 400, the first jig body 510 may be configured to overlap the electromagnet 420 of the alignment jig 500 in a plane. In an embodiment, the first clamp body 510 may include a metallic substance. Accordingly, the first clamp body 510 may be magnetically coupled with the electromagnet 420. That is, the first clamp body 510 may be a portion directly coupled with the coupling part 410 of the alignment device 400 through the electromagnet 420.

In an embodiment, the first clamp body 510 may include a first portion 512 overlapping the coupling member 410 of the alignment device 400 and a second portion 514 overlapping the support member 440 of the alignment device 400 in a plane. At this time, the lower level of the first portion 512 may be higher than the lower level of the second portion 514. In addition, the level of the lower face of the second portion 514 may be substantially the same as or similar to the level of the lower face of the second clamp body 520. In other words, the first clamp body 510 may have a shape of a cylinder when viewed in the second direction D2

The shape of the sides of the glyph.

In one embodiment, a clamping groove CH may be formed on the upper surface of the first clamp body 510. The clamping groove CH may be formed adjacent to the second clamp body 520. The clamping groove CH may provide a space for the clamping member 600 to be coupled to the alignment jig 500. The size of the clamping groove CH is not particularly limited as long as the clamping member 600 can be engaged with the clamping jig 500 to fix the same.

The second clamp body 520 may be connected to the first clamp body 510. Specifically, the second jig body 520 may be connected adjacent to the first jig body 510 in the first direction D1. For example, the second clamp body 520 may be connected adjacent to the second portion 514 of the first clamp body 510 in the first direction D1. When the alignment jig 500 is combined with the combining member 410 of the alignment apparatus 400, the second jig body 520 may be configured to be spaced apart from the combining member 410. Specifically, the second jig body 520 may be configured not to overlap the electromagnet 420 of the alignment jig 500 on a plane. In other words, the second clamp body 520 may be configured to be spaced apart from the electromagnet 420 on a plane. In addition, the second jig body 520 may be configured to overlap the support member 440 of the alignment device 400 in a plane. Therefore, as described above, even in the case where the alignment device 400 applies a force to the alignment jig 500, the second jig main body 520 may be supported by the support member 440. For example, in order to couple the alignment jig 500 to the second inspection socket 300, when the alignment device 400 applies a force to the alignment jig 500 in a direction opposite to the third direction D3, the second jig main body 520 is supported by the support member 440, so that a phenomenon in which the second jig main body 520 is lifted in the third direction D3 may be prevented. Thereby, deformation of the alignment jig 500 may be minimized or prevented.

In an embodiment, the second clamp body 520 may include a body portion 522 and a clamping portion 524. The body portion 522 may be a portion adjacent to the first clamp body 510. For example, the body portion 522 may be adjacent to the first clamp body 510 in the first direction D1. The clamping portion 524 may be a portion that does not overlap with the first clamp body 510. That is, the clamping portion 524 may be spaced apart from the first clamp body 510 on the front surface. For example, the clamping portion 524 may be formed to protrude from one surface of the body portion 522 by a certain length in the second direction D2. Thus, the clip portion 524 can function as a space for coupling the clip 600.

According to the embodiment, it may be that the second jig body 520 is configured to be spaced apart from the electromagnet 420 on a plane, and as the clamp 600 is coupled to the clamp groove CH and the clamp portion 524, the clamp 600 is coupled to the alignment jig 500 while avoiding the electromagnet 420. In other words, during the coupling of the clamp 600 to the alignment jig 500, interference between the clamp 600 and the electromagnet 420 and a collision phenomenon may be minimized or prevented. Thereby, the manufacturability of the contact process using the clip 600 can be further improved.

The insertion part 530 may be disposed under the second jig main body 520. For example, the insertion part 530 may be in a form protruding from the second jig body 520 in a direction opposite to the third direction D3 by a certain length and extending in the first direction D1. In an embodiment, the insertion portion 530 may extend in the first direction D1 to also overlap with the underside of the second portion 514 of the first clamp body 510. In an embodiment, the insertion part 530 may be provided in two. For example, the two insertion portions 530 may be spaced apart from each other in the second direction D2. Thus, in a coupling process of the alignment jig 500 and the second inspection socket 300, which will be described later, when the second connector C2 is coupled to the alignment jig 500 by suction, the insertion portion 530 may form a space in which the second connector C2 is disposed. In addition, the insertion part 530 may be directly inserted into the insertion space IS (refer to fig. 6) of the second inspection socket 300 in a coupling process of the alignment jig 500 and the second inspection socket 300, which will be described later. Thereby, the insertion part 530 may further improve the coupling accuracy of the alignment jig 500 and the second inspection socket 300 by preventing a phenomenon in which the alignment jig 500 is shaken or misaligned during the coupling with the second inspection socket 300.

Hereinafter, a coupling process of the second inspection socket 300 and the alignment jig 500 will be described in more detail with reference to fig. 1 and 5 to 10.

As described above, the position of the alignment jig 500 may be controlled by the alignment apparatus 400. First, the alignment jig 500 may be disposed above the second inspection socket 300 by the alignment device 400 to overlap the second inspection socket 300 on a plane. Thereafter, the alignment jig 500 may be vertically moved in a direction opposite to the third direction D3 by the alignment device 400. In other words, the alignment jig 500 may be lowered toward the second inspection socket 300 in a direction opposite to the third direction D3. At this time, the level of the upper face of the projection 312 may be the same as that of the upper face of the protection wall 340. Thereby, the moving path of the alignment jig 500 can be more smoothly ensured. In an embodiment, the second connector C2 supported by the socket main body 310 may be in a state of being coupled with the alignment jig 500 by suction before the alignment jig 500 is lowered. In other words, the alignment jig 500 may be lowered toward the second inspection socket 300 in a direction opposite to the third direction D3 in a state of being coupled with the second connector C2. At this time, the second connector C2 may be located in a space formed by the two insertion portions 530. For example, the second connector C2 may interface with the underside of the alignment fixture 500. The alignment jig 500 is lowered toward the second inspection socket 300 in a state of being coupled with the second connector C2 so that the second connector C2 can be supported by the socket main body 310 again. In addition, the insertion part 530 of the alignment jig 500 may be inserted into the insertion space IS. Thereby, it is possible to further improve the coupling accuracy of the alignment jig 500 and the second inspection socket 300 by preventing a phenomenon in which the alignment jig 500 is shaken or misaligned in the coupling with the second inspection socket 300. In one embodiment, the insertion portion 530 may be inserted into the insertion space IS to press the upper surface of the recess 314 of the socket main body 310. As the insertion part 530 presses the upper surface of the depression 314, the inspection pin 320 disposed in the socket main body 310 may protrude in the third direction D3 through the inspection groove IH. Thereby, the inspection pin 320 can be engaged with the second connector C2. For example, the inspection pin 320 may contact the lower face of the second connector C2. In one embodiment, the inspection pin 320 may be electrically connected with the second connector C2. Thus, the inspection pin 320 can function as a medium for electrically connecting the second connector C2 to another component.

The clamping member 600 may be fixed to the second inspection socket 300 by clamping the alignment jig 500. The clip 600 may include a clip hook 610 (refer to fig. 2) and a clip body 620 (refer to fig. 2).

The clamping hook 610 may be part of a direct fixation alignment fixture 500. The clamping hook 610 may clamp the alignment jig 500 by being coupled to the clamping groove CH and the clamping portion 524. Thereby, the alignment jig 500 may be fixed to the second inspection socket 300. In an embodiment, the clamping hook 610 may have a planar shape of a "U" shape when viewed in the third direction D3. Thus, when the clamp 600 clamps the alignment jig 500, the alignment jig 500 and the clamping hook 610 can form an imaging space VS (see fig. 4). The second connector C2 and a portion of the second inspection socket 300 located below the clamping hook 610 may be exposed through the imaging space VS when viewed in the third direction D3. Therefore, even after the clamp 600 is coupled to the alignment jig 500, the position information of the second connector C2 and the second inspection socket 300 can be collected using the imaging space VS. Therefore, the position information of the second connector C2 can be further effectively grasped. In addition, it is possible to further minimize or prevent the phenomenon of interference and collision with the alignment device 400 during clamping of the alignment jig 500 by the clamping hook 610 having a planar shape of a "U".

The grip body 620 may support the grip hook 610. The grip hook 610 may perform a parallel movement as well as a rotational movement by the grip body 620. For example, the grip hook 610 may be horizontally moved in the first direction D1 and the second direction D2 by the grip body 620. In addition, the clamping hook 610 may be rotatably moved by the clamp body 620 around an axis aligned with the second direction D2. Accordingly, the clamping hook 610 may be moved by the clamp body 620 to be selectively coupled with the alignment jig 500.

According to an embodiment, the display module contacting apparatus 1000 may include the electromagnet 420 and the clamping member 600, and perform a display module contacting process using the same. Thus, the alignment jig 500 may be selectively coupled with the alignment device 400 through the electromagnet 420. In addition, the alignment jig 500 may be selectively fixed to the second inspection socket 300 by the clamps 600. Accordingly, the alignment jig 500 may align the position of the second connector C2. In addition, the alignment jig 500 may attach the second connector C2 to the second inspection socket 300 by being combined with the second inspection socket 300. In addition, the alignment jig 500 may be fixed to the second inspection socket 300 by the clamp 600, thereby fixing the second connector C2 to the second inspection socket 300. Accordingly, during the inspection process for the display module DM after the contact process is performed, the state in which the second connector C2 is electrically connected to the second inspection socket 300 may be maintained. In particular, the display module contact device 1000 includes the electromagnet 420 and the clamp 600, and performs the contact process using the same, whereby separate manpower does not need to be invested for alignment and fixation of the second connector C2, and thus, the contact process can be performed quickly and accurately. Therefore, the manufacturability and efficiency of the contact process can be improved. In addition, since the display module contacting apparatus 1000 can combine the alignment jig 500 and the second inspection socket 300 by a simple structure including the electromagnet 420 and the clamp 600 and fix the alignment jig 500 and the second connector C2 to the second inspection socket 300, it is possible to simplify the apparatus and save process costs.

Hereinafter, a display module contacting method using the display module contacting apparatus 1000 will be described in more detail with reference to fig. 11 to 18.

Referring to fig. 11, the display module DM may be disposed on the table 100. The first and

second check sockets

200 and 300 may be previously configured on the table 100 before the display module DM is configured. In the configuration process of the display module DM, the position information for the first connector C1 obtained in advance may be utilized. Specifically, the display panel DP may be seated on the seating part 120 by adjusting the position of the display module DM to align the first connector C1 on the first checking receptacle 200. The overall position of the display module DM is adjusted and configured with reference to the first connector C1, so that the first connector C1 can be accurately aligned on the first checking receptacle 200. In the process of disposing the display module DM on the table 100, the second connector C2 may be disposed on the second checking socket 300. That is, if the display panel DP is seated on the seating part 120, the second connector C2 may be located on the second inspection socket 300.

The second connector C2 may comprise a material of a soft material. Thereby, the second connector C2 may be slightly deformed in its position or even shape during the manufacturing process or even during movement. For example, the relative position between the second connector C2 and the first connector C1 may be different for each display module. Therefore, when the display module DM is disposed on the table 100 with reference to the position information between the first connector C1 and the first check socket 200, the second connector C2 and the second check socket 300 may not be aligned accurately. That is, the second connector C2 disposed on the second checking receptacle 300 may be deviated from the original position. Therefore, a process of aligning the second connector C2 by collecting position information of the second connector C2 may be required.

Referring to fig. 12, the process of collecting the position information of the second connector C2 may be performed using the vision camera V. In an embodiment, a vision camera V may be located on the table 100. That is, the vision camera V may photograph the second connector C2 by being located on the work table 100. However, the position of the vision camera V is not necessarily limited thereto, and may be located below the table 100. At this time, it may be that the second inspection socket 300 is transparent, and the vision camera V photographs the second connector C2 under the second inspection socket 300. In an embodiment, the relative position information between the second connector C2 and the second checking receptacle 300 may be collected using the alignment mark of the second connector C2. In addition, the alignment mark may be used to collect relative position information between the second connector C2 and the first connector C1. In addition, the relative position information between the second connector C2 and the display panel DP may be collected using the alignment mark.

Referring to fig. 13 to 16, the second connector C2 may be attached to the second inspection socket 300 by moving the alignment jig 500 with the alignment device 400. First, as shown in fig. 14, the alignment jig 500 moved by the alignment device 400 may be positioned above the second inspection socket 300. That is, the second connector C2 disposed on the second inspection socket 300 may be disposed below the alignment jig 500. At this time, it may be that the electromagnet 420 takes on the property of a magnet by the power supply E supplying power to the electromagnet 420. Thus, the alignment jig 500 may be coupled to the alignment device 400, and thus the alignment jig 500 may move together with the movement of the alignment device 400.

Thereafter, as shown in fig. 15, the second connector C2 may be sucked to the alignment jig 500 using vacuum pressure. Specifically, a vacuum hole VH penetrating the lower surface of the alignment jig 500 may be formed at the lower surface of the alignment jig 500. In addition, a vacuum pressure distribution space to distribute the vacuum pressure may be provided inside the alignment jig 500. The vacuum pump may supply the vacuum pressure to the vacuum pressure distribution space through the vacuum tube 450 of the alignment apparatus 400, and the vacuum pressure is transmitted to the second connector C2 through the vacuum hole VH, thereby adsorbing the second connector C2 to the alignment jig 500. For example, the second connector C2 supported by the socket main body 310 of the second inspection socket 300 may be lifted in the third direction D3 from the upper surface of the socket main body 310 by the vacuum pressure. In an embodiment, when the second connector C2 includes a soft material, the second connector C2 may be bent while being attracted to the alignment jig 500.

Thereafter, as shown in fig. 16, the alignment jig 500 may be moved using the alignment apparatus 400 in a state in which the second connector C2 is sucked to the alignment jig 500, thereby aligning the position of the second connector C2. For example, the position of the second connector C2 may be aligned with the original position. Thereafter, the alignment jig 500 may be combined with the second inspection socket 300 by lowering it toward the second inspection socket 300. Thereby, the second connector C2 combined with the alignment jig 500 may be seated on the second inspection socket 300. In addition, the second connector C2 is seated on the second inspection socket 300 after being aligned with the home position, and thus the second connector C2 can be electrically connected to the second inspection socket 300.

Referring to fig. 17, the alignment jig 500 may be clamped by moving the clamp 600. Thereby, the alignment jig 500 may be fixed to the second inspection socket 300. The clamp 600 may be coupled to the alignment jig 500 while avoiding interference and collision of the electromagnet 420 of the alignment device 400.

Referring to fig. 18, the alignment device 400 may be separated from the alignment jig 500 in a state where the alignment jig 500 is clamped by the clamps. For example, the coupling member 410 may be separated from the alignment jig 500 by the movement of the moving member 430. At this time, the power supply of the power supply portion E (refer to fig. 16) to the electromagnet 420 is interrupted, and the electromagnet 420 may be in a state of losing the magnet property. Thus, if the coupling member 410 is moved by the moving member 430, the alignment jig 500 may be separated from the coupling member 410. However, since the alignment jig 500 is in a state of being fixed on the second inspection socket 300 by the clamp 600, the alignment jig 500 may remain on the second inspection socket 300 even if the alignment device 400 is separated from the alignment jig 500. Thereby, the second connector C2 can be continuously fixed to the second check socket 300. That is, the state in which the second connector C2 and the second check socket 300 continue to be electrically connected can be maintained. Accordingly, in the display module inspection process performed after the contact process, an inspection signal may be applied to the display panel DP through the table 100, the second inspection socket 300, and the second connector C2 in a state in which the second connector C2 is electrically connected to the second inspection socket 300. Thereby, the inspection process for the display module DM may be more smoothly performed.

According to an embodiment, the display module contacting method using the display module contacting apparatus 1000 may control the position of the alignment jig 500 according to the movement of the alignment apparatus 400 by selectively combining the alignment apparatus 400 and the alignment jig 500 using the electromagnet 420. Thereby, the alignment jig 500 may align the position of the second connector C2. In addition, the alignment jig 500 may attach the second connector C2 to the second inspection socket 300 by being combined with the second inspection socket 300. In addition, the alignment jig 500 may be fixed to the second inspection socket 300 by the clamp 600, thereby fixing the second connector C2 to the second inspection socket 300. Accordingly, during the inspection process for the display module DM after the contact process is performed, the state in which the second connector C2 is electrically connected to the second inspection socket 300 may be maintained. In particular, according to the display module contacting method using the display module contacting apparatus 1000, the contacting process may be performed by using the electromagnet 420 and the clamp 600 together, whereby separate manpower does not need to be invested for alignment and fixing of the second connector C2, and thus, the contacting process may be performed quickly and accurately. Therefore, the manufacturability and efficiency of the contact process can be improved. In addition, since the display module contacting apparatus 1000 can combine the alignment jig 500 and the second inspection socket 300 by a simple structure including the electromagnet 420 and the clamp 600 and fix the alignment jig 500 and the second connector C2 to the second inspection socket 300, it is possible to simplify the apparatus and save process costs.
