Specifically, as for the three adjustment mechanisms described above, the first direction adjustment mechanism 61 and the second direction adjustment mechanism 62, as the name implies, are used to adjust the position of the limiting device 7 in the first direction x and the second direction y, respectively, and thus the second direction y is perpendicular to the first direction x in keeping with the foregoing description.

Taking the specific structure of the second direction adjustment mechanism 62 as an example, in the present embodiment, the second direction adjustment mechanism 62 includes a first moving member 621 and a second moving member 622, wherein the first moving member 621 is fixed to the sliding block 412, and the second moving member 622 is disposed on a side of the first moving member 621 away from the sliding block 412, and is configured to be slidably connected to the first moving member 622 in a manner that the relative position of the first moving member 622 can be adjusted in the second direction y. The specific position adjustment can be realized by a roller arranged between the first moving member 621 and the second moving member 622, and various other embodiments such as a slide rail and a slide groove can also be provided. In this embodiment, the second adjusting mechanism 62 further includes an adjusting lever 623 extending along the first direction x and used for coarsely adjusting the relative position between the first moving member 621 and the second moving member 622, and an adjusting knob 624 used for finely adjusting the relative position, so as to realize manual adjustment under abnormal conditions where automatic adjustment cannot be performed. Of course, the above-described configurations and positions of the adjustment lever 623 and the adjustment knob 624 may alternatively be implemented in other embodiments as a signal line 623 and a locking key 624 for transmitting an adjustment signal and maintaining the second adjustment mechanism 62 in a currently unknown state, respectively.

The first adjustment mechanism 61 disposed on the side of the second adjustment mechanism 62 facing away from the sliding block 412 in the present embodiment is configured to have the same structure as the second adjustment mechanism 62, and only differs in the disposed orientation to realize the position adjustment in the first direction x, which should be understood by those skilled in the art. The angle adjusting mechanism 63 is distinguished from other adjusting mechanisms by comprising a fixing surface 631 and a rotating rod 632, after the angle adjusting mechanism 63 directly or indirectly receives the adjusting signal, the rotating rod 632 adjusts the inclination angle of the fixing surface 631, and the fixing surface 631 is fixed on the side departing from the display module 100 with the limiting device 7. Of course, in other embodiments of the present invention, the position and the characteristic structure of the angle adjusting mechanism 63 may be alternatively implemented as the suction mechanism 63, and the suction mechanism 72 disposed in the limiting device 7 in this embodiment is eliminated, so as to reduce the volume occupation of the limiting device 7.

As shown in fig. 8, the detecting device 23 includes a fixing base 231 extending perpendicular to the plane of the display module 100, i.e. along the third direction z in the present embodiment, and a sliding plate 232 slidably connected to the fixing base 231, wherein an end of the sliding plate 232 is provided with a test contact 8 corresponding to the test terminal 101 of the display module 100. In this way, the sliding plate 232 is slidably connected to the fixing base 231 along the third direction z to drive the test contact 8 at the end to move, so as to selectively contact the test terminal 101 of the display module 100 on the stage 21 reciprocating under the detecting device 23, so as to light up the display module 100 or detect other screen parameters.

The fixing base 231 specifically includes a guide 2311 and a guide rail 2312, the guide 2311 is used for guiding the flexible circuit board 80 to be connected to the test contacts 8 and is disposed at least on one side surface of the fixing base 231 extending along the third direction z and close to the sliding plate 232, and in the present embodiment, two guide 2311 are disposed at intervals on the side surface of the fixing base 231 extending along the third direction z. The sliding plate 232 specifically includes a sliding portion 2321 and an extending portion 2322, wherein the sliding portion 2321 is disposed corresponding to and slidably connected to the guide rail 2312, in this embodiment, the sliding portion 2321 is sleeved on the guide rail 2312, the extending portion 2322 is used for fixing the test contact 8 at an end, and for contacting with a display module below, the extending portion 2322 is configured to be perpendicular to the sliding portion 2321 extending and moving along the third direction z and extend in a direction away from the fixing base 231. In the present embodiment, the extension 2322 and the sliding part 2321 form an "L" shaped structure.

As shown in fig. 9 to 11, which are schematic perspective views of the test fixture 20 in the verification, calibration and detection states, respectively, it is worth explaining that, compared to fig. 2, 4 and 5, the test fixture 20 shown in fig. 9 to 11 hides a drag chain configured as a reel-type folding or unfolding and disposed on one side of the object stage 21 to prevent the drag chain from shielding other structures on the test fixture 20 from interfering with description, and of course, the drag chain is disposed to supply power and/or transmit an adjustment signal to the object stage 21, and those skilled in the art can generate various other embodiments easily conceivable with the benefit of this technology.

Further, as shown in fig. 9, when the test fixture 20 is in the verification state, the linear motor 5 drives the sliding block 412 to move along the first direction x formed by the sliding rail 411 and the abdicating gap 414 to the direction close to the code scanning device 221, the sliding block 412 sequentially drives the adjusting device 6 and the limiting device 7, and further drives the display module 100 to move, so that the identification code 102 on the display module 100 is moved to the position below the code scanning device 221 and aligned, in the alignment process, since the sensing range of the code scanning device 221 is configured to be much larger than the area of the identification code 102 in the present embodiment, the verification can be completed without the action of the adjusting device 6, and of course, in other embodiments, the adjusting device 6 may be configured to automatically adjust the position of the limiting device 7 to affect the position of the identification code 102, as long as the alignment is finally achieved.

After the code scanning device 221 acquires the information carried in the identification code 102, the information may be transmitted to one side of the main control device 30 and stored, and then the main control device 30 provides a trigger signal for the identification camera 222 and the linear motor 5, respectively, so that the identification camera 222 is in a working state, and the linear motor 5 is triggered to provide a driving force for the sliding block 412, so that the test fixture 20 enters a next working state. Of course, in the embodiment where information storage is not required, the identification code 102 may directly provide the identification camera 222 and the linear motor 5 to trigger the signal after acquiring the information. In this process, the sliding plate 232 of the detecting device 23 is always located at the initial position, i.e. away from the farthest end of the display module 100 in the third direction z, and interferes with the limiting device 7 or the display module 100 in the subsequent moving process, thereby causing structural damage.

Continuously, as shown in fig. 10, the linear motor 5 drives the sliding block 412 to move on the sliding rail 411, so as to drive the display module 100 to move downward from the code scanning device 221 to the recognition camera 222, while the sliding plate 232 of the detection device 23 keeps the relative position unchanged. When the display module 100 is completely moved to a position below the recognition camera 222, the recognition camera 222 responds to and captures an entire image of the object plane 71 including the display module 100, that is, the recognition camera 222 can capture an entire image of the object plane 71 by covering the object table 21. The recognition camera 222 transmits the image to the main control device 30 for performing a bit state analysis of the display module 100, and the main control device 30 further converts the analysis result into adjustment signals for the first adjusting mechanism 61, the second adjusting mechanism 62 and the angle adjusting mechanism 63 and outputs the adjustment signals, so as to respectively adjust the inclination angles of the first direction x, the second direction y and the object plane 71.

After the calibration state shown in fig. 10, the test terminals 101 on the display module 100 are adjusted to the predetermined position, which is defined as the position where the display module 100 is translated along the first direction x to be under the test contacts 8, and the test terminals 101 are sufficiently contacted by the translation of the test contacts 8 along the third direction z. Therefore, as shown in fig. 11, after the calibration state is finished, the verifying device 22 is configured to send a trigger signal to the detecting device 23 directly or through the main control device 30, so that the detecting device is in a working state; the linear motor 5 drives the sliding block 412 to drive the object placing plane 71, so as to move the display module 100 to the lower part of the detection device 23, so that the detection device 23 can be used for lighting the display module or performing other detection operations through the contact between the test contact 8 and the test terminal 101.

In this process, in one embodiment, the user can adjust the relative positions of the first moving member 621 and the second moving member 622 by the adjusting lever 623 and/or the adjusting knob 624 to compensate for the deviation of the feedback adjustment formed by the "recognition camera 222 — adjusting device 6"; in another embodiment, the user can also send an interrupted adjustment signal to the signal line 623 through the main control device 30 to adjust the position, and of course, under the condition of repeatedly detecting the same size type of display module 100, the user can lock the position configuration of the adjusting device 6 through the locking key 624. Of course, the above description is for the second adjustment mechanism 62 by way of example, and the above configuration is equally applicable to the first adjustment mechanism 61.

For the implementation manner of triggering the corresponding actions after the display module 100 is respectively moved to the positions below the code scanning device 221, the recognition camera 222 and the detection device 23, in addition to mutual signal communication among the code scanning device 221, the recognition camera 222 and the detection device 23 to realize mutual triggering, the triggering can be realized by using a coding signal generated by the linear motor 5, and electronic components such as a photoelectric sensor can also be arranged on the slide rail 411 to sense the position of the slide block 412, so as to trigger the corresponding devices or devices to act respectively.

For a clearer observation and comparison of the operation of the test contact 8 and its related structure, the part a shown in fig. 11 is enlarged to obtain a partially enlarged schematic view of the part a in two bit states of the detection device, i.e., fig. 12 and 13.

As shown in fig. 12, the flexible circuit board 80 extends to the end of the fixing base 231 along the third direction z, and sequentially extends to the direction close to the sliding portion 2321 and the extending portion 2322 along the second direction y and the third direction z, respectively, so as to be electrically connected to the test contact 8, the electrical connection mode may be direct connection, or may establish a connection relationship with the test contact 8 through a cable socket 2324 disposed on the extending portion 2322, and of course, in other embodiments, the cable socket 2324 may also serve as an expansion interface to change the functional configuration of the test contact 8 or the detection device 23.

Specifically, some details are included between the fixed seat 231 and the sliding plate 232, and particularly between the guide rail 2312 and the sliding part 2321. On one hand, the guide track 2312 is provided with a stopper 2313 extending in the second direction y at least near the end side where the sliding part 2321 and the extending part 2322 are connected, so as to limit the movement of the sliding plate 232 in the third direction z. One of the guide rail 2312 and the sliding part 2321 is provided with a buffering head 2314, and the other is provided with a buffering seat 2323 which is matched with the buffering head 2314, so that when the sliding plate 232 moves to the limit position along the third direction z, buffering and/or damping are provided for the action of the sliding plate 232. For the limit position, the test contact 8 disposed at the end of the sliding plate 232 is defined to be the farthest position allowed by the movement of the test contact 8 from the initial state to the test terminal 101 of the display module 100 along the third direction z, and the limit position is defined and the buffer seat 2323 and the punch 2314 are disposed to prevent the test contact 8 from pressing the display module 100.

In this embodiment, the buffering head 2314 is disposed on at least one side of the guiding rail 2312, the buffering seat 2323 is correspondingly disposed on at least one side of the sliding portion 2321, and the buffering seat 2323 is located above the buffering head 2314, so as to provide a better damping and buffering effect.

When the detecting device 23 is triggered and moves close to the test terminal 101 of the display module 100 along the third direction z, the test contact 8 contacts with the test terminal 101 to form the second position shown in fig. 13. The flexible circuit board 80 is stretched at this time; the stopper 2313 disposed on the guide rail 2312 on the fixing base 231 abuts against one of the sliding portion 2321, the extending portion 2322, or a connecting portion of the sliding portion 2321 and the extending portion 2322, so as to prevent the sliding plate 232 from moving closer to the display module 100. During movement, the damping head 2314 contacts the damping seat 2323 and provides damping and damping to slow the movement of the sliding plate 232.

In summary, according to the test board for the display module provided by the utility model, the box body 1, the main control device 30 and the test fixture 20 are configured to be detachably connected, and the test fixture 20 is detachably mounted on the upper surface of the box body 1 and selectively connected with the main control device 30, so that the technical effects of facilitating adjustment of the test board function by a user, facilitating later maintenance of the test fixture and facilitating reasonable allocation of a working area in a workshop are achieved.
