[0036] The present application provides a display panel correction device for improving detection efficiency and meeting the detection needs of Block-shaped panels. The specific implementation process of the present application is described as follows.

[0037] Please refer to Figures 1 to 8 The display panel correction device provided by the present application comprises:

[0040] The detection module 05 comprises a mounting plate 06, one end of the mounting plate 06 is fixed on the X-axis movement module 04, and the other end is movably connected with a plurality of adjusting plates 07, the adjusting plates 07 are controlled to move on the mounting plate 06, and one correction probe is correspondingly arranged on each adjusting plate 07. In the detection process, the distance between the adjacent two correction probes 08 can be adjusted by adjusting the distance between the adjacent two adjusting plates 07 on the mounting plate 06. The number of the correction probes 08 is the same as that of the adjusting plates 07, and the plurality of correction probes 08 are on the same horizontal plane, and the plurality of correction probes 08 can simultaneously detect the display panel 09. The correction probe 08 adopts a Gamma correction probe 08.

[0041] Based on the plurality of adjusting plates 07, the detection module 05 is provided with a plurality of correction probes 08, each correction probe 08 can detect one display panel 09 at a time or detect one area on the display panel 09 at a time, so that the plurality of display panels 09 can be detected at a time or the plurality of areas on the display panel 09 can be simultaneously detected, the detection efficiency is improved, and the detection of the Block form panel (i.e. a panel composed of a plurality of display screens) is suitable. When three display panels need to be detected at the same time, three adjusting plates 07 and three correction probes 08 can be arranged in the corresponding detection module 05, thereby improving the limitation of the existing Gamma detection.

[0042] In the embodiment, the mounting plate 06 is arranged on the detection module 05, the plurality of adjusting plates 07 are arranged on the mounting plate 06, the plurality of detection probes 08 are arranged corresponding to the adjusting plates 07, the spatial position of the detection module 05 is changed by cooperation of the Z-axis movement module 02, the Y-axis movement module 03 and the X-axis movement module 04, the distance between the correction probes 08 is changed by changing the positions of the adjusting plates 07, and the plurality of correction probes 08 simultaneously detect the plurality of display panels 09, so that, compared with the prior art, the plurality of display panels 09 can be detected at the same time at a time, and the plurality of areas (points) on the single display panel 09 can be simultaneously detected, the detection efficiency is improved, the detection demand of the Block form panel (i.e. a panel composed of a plurality of display screens) is met, and the limitation is improved.

[0043] Please continue to refer to 2 and Figure 3 In an optional embodiment, the adjusting plate 07 comprises a fixed plate 10 and a sliding plate 11, the fixed plate 10 is fixed on the mounting plate 06, one side of the sliding plate 11 is movably connected with the fixed plate 10, the other side is connected with the correction probe 08, and an adjusting piece is arranged between the sliding plate 11 and the fixed plate 10. The adjusting piece is controlled to control the sliding plate 11 to move on the fixed plate 10.

[0044] In the embodiment, one side of the slide plate 11 is connected with the fixed plate 10 through components such as slide rails, pins, etc., so that the slide plate 11 can move in the vertical direction on the fixed plate 10. The other side of the slide plate 11 is connected with the correction probe 08, so that the movement of the slide plate 11 drives the correction probe 08 to move, thereby adjusting the position of the correction probe 08 on the mounting plate 06.

[0045] The adjusting member is controlled to accurately control the moving distance and position of the slide plate 11 on the fixed plate 10. The adjusting member can be manually adjusted or electrically adjusted (electric driver). By adjusting the adjusting member, the position of the slide plate 11 can be easily changed, and the position (in the vertical direction) of the correction probe 08 can be adjusted.

[0046] In an optional embodiment, the side of the fixed plate 10 is provided with a first scale 12, and the side of the slide plate 11 is provided with a pointing mark 13, which points to the first scale 12.

[0047] The first scale 12 and the pointing mark 13 are on the same side, or the first scale 12 is arranged on both sides of the fixed plate 10, and the pointing mark 13 is arranged on both sides of the slide plate 11. The pointing mark 13 is an elongated pointer or a small component with an arrow shape or a triangular shape, which is fixed to the edge of the side of the slide plate 11 and can freely rotate or slide with the movement of the slide plate 11. The pointing mark 13 clearly points to the first scale 12 on the fixed plate 10, and the pointing mark 13 points to different positions of the first scale 12 line with the movement of the slide plate 11, thereby providing instant position feedback.

[0048] To enhance readability, the first scale line is designed with different thicknesses and numerical markings, so that the operator can quickly and accurately read the current position. The scale unit can be millimeters, centimeters, inches, etc., or even more precise micrometer units. Here, the scale unit is not limited in detail, and the achievable one is used.

[0049] Please continue to refer to Figure 3 In an optional embodiment, the adjusting member is an adjusting bolt 14, the fixed plate 10 is provided with a first extension plate 15, the slide plate 11 is provided with a second extension plate 16 parallel to the first extension plate 15, and the adjusting bolt 14 is arranged between the first extension plate 15 and the second extension plate 16. The adjusting bolt 14 is used to adjust the distance between the first extension plate 15 and the second extension plate 16.

[0050] In the embodiment, the slide plate 11 is controlled to move vertically in a precise manner by manual adjustment. Specifically, the position of the first extension plate 15 is opposite to the position of the second extension plate 16, and the two positions are parallel to each other. The adjusting member is an adjusting bolt 14, which is composed of a head (such as a hexagonal head, a slot head or a cross slot head) and a threaded rod. The adjusting bolt 14 is arranged between the first extension plate 15 and the second extension plate 16. By rotating the bolt head, the second extension plate 16 moves axially under the cooperation of threads, thereby changing the relative distance between the first extension plate 15 and the second extension plate 16, and achieving the movement of the slide plate 11.

[0051] The manual adjustment manner has high precision, and can achieve very subtle changes in distance by adjusting the rotation angle of the bolt, thereby meeting the requirements of various application scenarios. By manual adjustment, the two correction probes 08 are adjusted to be at the same horizontal height.

[0052] In an optional embodiment, the mounting plate 06 is provided with a second scale 17, and the adjusting plate 07 is provided with an extension pointer 18, which points to the second scale 17.

[0053] The two adjusting plates 07 are respectively fixed on the mounting plate 06 by bolts or screws, and the second scale 17 is arranged on the mounting plate 06. The extension pointer 18 is a part of the adjusting plate 07 and is integrally formed with the adjusting plate 07. The extension pointer 18 is provided with a sharp end, which always points to the second scale 17.

[0054] When it is necessary to detect two display panels 09 at the same time, it is necessary to adjust the distance between the two correction probes 08 according to the distance between the two display panels 09. Therefore, in the embodiment, the adjusting plate 07 can be moved by manual operation (loosening the bolts or screws between the adjusting plate 07 and the mounting plate 06), and then the adjusting plate 07 is moved. After adjustment, the bolts or screws are tightened again. With the movement of the adjusting plate 07, the extension pointer 18 also moves correspondingly and points to different positions on the second scale 17 in real time. By observing the scale value pointed by the extension pointer 18 on the two adjusting plates 07, the distance between the two correction probes 08 can be accurately understood, thereby achieving precise adjustment and feedback.

[0055] In addition, the movement direction of the adjusting plate 07 on the mounting plate 06 is parallel to the axial direction of the X-axis. Therefore, by adjusting the movement of the two adjusting plates 07 on the mounting plate 06, the adjustment and movement of the two correction probes 08 along the X-axis direction are realized.

[0056] Please continue to refer to Figure 4In an alternative embodiment, the correction probe 08 is provided with an extension 19, and the slide plate 11 is provided with a groove 20 in the vertical direction on the side facing the correction probe 08, the extension 19 is embedded in the groove 20, and the correction probe 08 is controlled to move along the groove.

[0057] The groove 20 is located on the side of the slide plate 11 facing the correction probe 08, the two ends of the groove 20 are flush with the two ends of the slide plate 11, the depth of the groove 20 is sufficient to accommodate the extension 19, and the width of the groove 20 is slightly larger than the maximum width of the extension 19 to provide the necessary assembly tolerance.

[0058] The extension 19 can be integrally formed with the correction probe 08 or fixed to the correction probe 08 by bolts, screws or buckles, and the extension 19 is connected to the groove 20 by bolts, and the shape of the extension 19 depends on the design of the groove 20 on the slide plate 11, such as rectangular or oval.

[0059] In this embodiment, the cooperation of the groove 20 and the extension 19 allows the extension 19 to move along the track formed by the groove 20 when manually adjusting the height of the correction probe 08, and the groove 20 is arranged in the vertical direction, so that the correction probe 08 can move in the vertical direction, thereby eliminating the need to reposition the detection direction of the correction probe 08.

[0060] In an alternative embodiment, the Y-axis motion module 03 is provided with a connecting plate 21, the center of the connecting plate 21 is fixed to the Y-axis motion module 03, and the two ends of the connecting plate 21 are respectively fixed with X-axis motion modules 04.

[0061] The two ends of the connecting plate 21 are both fixed with X-axis motion modules 04, and the middle position of the connecting plate 21 is connected with the Y-axis motion module 03, so that the Y-axis motion module 03 can control the connecting plate 21 to move along the axis direction of the Y-axis motion module 03, thereby the Y-axis motion module 03 can control the movement of the two groups of X-axis motion modules 04 at the same time.

[0062] The two groups of X-axis motion modules 04 are responsible for moving the detection module 05 in the axis direction of the X-axis motion module 04, realizing the simultaneous scanning and detection of multiple display panels 09, and meeting the detection needs of the Block-shaped Panel (i.e. a panel composed of multiple display screens) that appears today. One or more detection modules 05 can be installed on each X-axis motion module 04, thereby realizing the simultaneous work of multiple detection modules 05. By providing the connecting plate 21, the detection efficiency is improved, and the flexibility of detection is increased, which can flexibly meet the detection needs of display panels 09 of different sizes and types.

[0063] In an optional embodiment, the X-axis movement module 04 comprises a servo motor 22, a screw rod guide 23 and a sliding block 24. The servo motor 22 is connected to the screw rod guide 23 through a transmission assembly 25. The sliding block 24 is arranged on the screw rod guide 23 and is used to be connected to the detection module 05. The servo motor 22 controls the movement of the sliding block 24 through the screw rod guide 23. The number of the sliding blocks 24 is at least two.

[0064] In the embodiment, the servo motor 22 is the power source of the X-axis movement module 04 and is used to control the rotation of the screw rod guide 23. The screw rod guide 23 is the transmission and guide component in the X-axis movement module 04 and converts the rotary motion of the servo motor 22 into the linear motion of the sliding block 24.

[0065] The transmission assembly 25 is used to connect the servo motor 22 and the screw rod guide 23 and to transmit the torque and rotation speed of the servo motor 22 to the screw rod guide 23, so as to drive the sliding block 24 to move linearly. The transmission assembly 25 can adopt the combination of a shaft coupling, a speed reducer and the like. One side of the sliding block 24 is connected to the screw rod guide 23, and the other side is used to be connected to the detection module 05. The sliding block 24 moves linearly along the screw rod guide 23.

[0066] On the screw rod guide 23, the number of the sliding blocks 24 is at least two. Since each sliding block 24 can be connected to one detection module 05, at least two detection modules 05 can be arranged on the same X-axis movement module, which can further increase the number of the correction probes 08 and thus increase the detection efficiency.

[0067] In addition, it can be understood that the same structure (consisting of the servo motor 22, the screw rod guide 23, the transmission assembly 25 and the sliding block 24) of the X-axis movement module 04 can be adopted on the Z-axis movement module 02 and the Y-axis movement module 03. The difference is that the sliding block 24 on the Z-axis movement module 02 is connected to the Y-axis movement module 03, and the sliding block 24 on the Y-axis movement module 03 is connected to the connecting plate 21 or the X-axis movement module 04.

[0068] Please continue to refer to Figure 5 In an optional embodiment, a stroke sensor 26 is fixed on the screw rod guide 23, and a sensing sheet 27 is arranged on the sliding block 24. The sensing sheet 27 moves through the stroke sensor 26 along with the sliding block 24.

[0069] In the embodiment, the stroke limit sensor is fixed on the screw guide rail 23, and the stroke limit sensor is used to detect the position of the slider 24 in real time, so as to detect the position of the detection module 05. The sensing sheet 27 is a specific element fixed on the slider 24, which can be a metal sheet, a magnetic material or other materials that can be recognized by the stroke sensor 26. The sensing sheet 27 is arranged on the side of the slider 24, and when the sensing sheet 27 moves to the vicinity of the sensor with the slider 24, the sensing sheet 27 can effectively trigger the sensor. Of course, in some embodiments, the stroke sensor 26 can be installed in multiple, and the specific implementation is subject to the actual situation.

[0070] The stroke sensor 26 in the embodiment can be a contact type (such as a mechanical switch) or a non-contact type (such as a photoelectric sensor, a magnetic induction sensor, etc.), and the specific implementation is subject to the actual situation.

[0071] In the embodiment, when the slider 24 moves on the screw guide rail 23, the sensing sheet 27 fixed on the slider 24 also moves, and when the sensing sheet 27 passes through the stroke sensor 26 installed on the guide rail, the sensor detects the presence (or change) of the sensing sheet 27 and immediately triggers an electrical signal or a digital signal. The signal can be received and processed by the control system, which is used to monitor the current position of the slider 24, judge whether the stroke is completed, or trigger other related control actions (such as stopping movement, changing the direction of movement, etc.).

[0072] In an optional embodiment, a right-angle plate 28 is fixed on the Z-axis movement module 02, and the Y-axis movement module 03 is fixed on the right-angle plate 28.

[0073] The right-angle plate 28 is a bridge connecting the Z-axis movement module 02 and the Y-axis movement module 03, which is used to provide a stable support platform for the Y-axis movement module 03 and ensure that the movement of the Y-axis movement module 03 in the horizontal plane (XY plane) is not affected by the Z-axis movement module 02. The right-angle plate 28 is a rectangular or L-shaped plate, one side of the right-angle plate 28 is fixedly connected with the slider 24 of the Z-axis movement module 02, and the other side perpendicular thereto is used to fix the Y-axis movement module 03.

[0074] In the embodiment, the Z-axis movement module 02 is used to drive the right-angle plate 28 to move along the Z-axis direction (vertical direction), so as to adjust the vertical movement of the Y-axis movement module 03, the X-axis movement module 04 and the detection module 05.

[0075] In a preferred mode, two adjusting plates 07 are arranged on the mounting plate 06, and the number of correction probes 08 is two, and one correction probe is connected to each adjusting plate 07. The distance between the two adjusting plates 07 on the mounting plate 06 can be adjusted, which can be manually adjusted or automatically adjusted by setting a driver such as a pneumatic cylinder, a motor and a screw drive.

[0076] Please continue to refer to Figure 8 In this optional embodiment, automatic adjustment is arranged between the two adjusting plates 07. Specifically, a double-head cylinder 29 is arranged on the mounting plate 06, two ends of the double-head cylinder 29 are respectively connected with the two adjusting plates 07, the double-head cylinder 29 is used to drive the adjusting plates 07 to move on the mounting plate 06, the double-head cylinder 29 is fixed on the mounting plate 06, and specifically, buckle connection or bolt connection can be adopted, and the double-head cylinder 29 is actually connected with the fixed plate 10 in the adjusting plate 07.

[0077] In this embodiment, the two ends of the double-head cylinder 29 are arranged on telescopic rods, each telescopic rod is connected with one adjusting plate 07 (connected with the fixed plate 10 in the adjusting plate 07), the double-head cylinder 29 can simultaneously control the two fixed plates 10 to move relatively or oppositely, or can individually control one fixed plate 10 to move, so that the distance adjustment between the two fixed plates 10 is realized, and different specifications of the display panel 09 are facilitated to be adapted.
