[0022] Combination Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this application embodiment provides a screen detection device 10, including: Detection module 200, comprising a rotatable turntable 230, a plurality of carrier groups 220 arranged sequentially on the turntable 230 along the rotation direction of the turntable 230, and AOI detection equipment and Pre-gama detection equipment arranged at intervals along the circumference of the turntable 230 on its outer side; and The loading / unloading module 100 includes a base 110, a loading bin 121, a first robotic arm 130 and a second robotic arm 140, a loading platform 210 disposed alongside the turntable 230, and a transfer mechanism 180 for transferring the screen to be tested on the loading platform 210 to a carrier group 220 at a preset position. The first robotic arm 130 and the second robotic arm 140 are movably disposed on the base 110. The first robotic arm 130 is used to transfer the screen to be tested in the loading bin 121 to the loading platform 210. The second robotic arm 140 is used to transfer the tested screen on the carrier group 220 at the preset position to the unloading station.

[0023] In the technical solution of this application embodiment, the screen detection device 10 is divided into two main modules: a detection module 200 and a loading / unloading module 100. The detection module 200 is equipped with a rotatable turntable 230, and multiple carrier groups 220 arranged sequentially along the rotation direction of the turntable 230, and AOI detection equipment and Pre-gama detection equipment arranged sequentially and spaced apart along the circumference of the turntable 230 on its outer side. The screen detection device is activated by the rotation of the turntable 230. Figure 3(Diagram of curved arrow) This allows the screens on the carrier group 220 to pass through the Pre-gama inspection equipment and the AOI inspection equipment; and multiple carrier groups 220 are set up so that during inspection, the screens on different carrier groups 220 are inspected by the Pre-gama inspection equipment and the AOI inspection equipment respectively, improving inspection efficiency. The loading and unloading module 100 uses the first robot arm 130 and the second robot arm 140 to load and unload respectively, and the transfer mechanism 180 is set up to transfer the screens to be inspected from the loading bin 121 to the loading platform 210 by the first robot arm 130 to a preset position ( Figure 3 (Illustrated by dotted line 1), and at the preset position, the second robotic arm 140 transfers the screen that has been inspected to the unloading station. Figure 3 (Dash line in the middle (2) indicates that the material is loaded into the detection module 200 at the preset position and unloaded from the preset position to complete the detection of the screen; the loading and unloading are completed in the same preset position, which not only saves the arrangement space of the turntable 230 but also helps to save time and improve detection efficiency.

[0024] In some embodiments, the loading platform 210 is mounted on the transfer mechanism 180, which is used to transfer the loading platform 210 to a position corresponding to a preset position. The transfer mechanism 180 also includes a transfer robot, which transfers the screen on the loading platform 210 to the carrier assembly 220 at the preset position. In this embodiment, In some embodiments, the transfer mechanism 180 may include a transfer robot for transferring a screen on the loading platform 210 to a carrier group 220 at a preset position.

[0025] In this embodiment, the turntable 230 is driven by a rotatable drive mechanism, such as a direct drive by a motor or a motor and a transmission mechanism. The motor can be a stepper motor.

[0026] In some embodiments, there are multiple carrier groups 220, so that during inspection, carrier groups 220 are present at both the Pre-gama inspection equipment and the AOI inspection equipment. For example, in one embodiment, there are five carrier groups 220; during the inspection cycle, three carrier groups 220 are located at the Pre-gama inspection equipment, the first AOI inspection equipment, and the second AOI inspection equipment, respectively, one group is located at a preset position, and the remaining group is located at the cleaning station. When the turntable 230 rotates once, each carrier group 220 sequentially passes through the preset position, the Pre-gama inspection equipment, the first AOI inspection equipment, the second AOI inspection equipment, and the cleaning station. In one embodiment, the cleaning station is equipped with a cleaning mechanism 260 for cleaning the screen after inspection; after cleaning, the carrier group 220 is moved to the preset position for unloading and loading the next batch of materials.

[0027] As an optional implementation of the above embodiments, the detection module 200 further includes a first image acquisition device and a first adjustment mechanism. The first image acquisition device is set corresponding to the preset position and is used to capture a first image at the preset position. The adjustment mechanism is configured to adjust the position of the standby screen at the preset position according to the first image, so that the screen to be detected accurately reaches the carrier, facilitating subsequent detection. The first image acquisition device is used to capture an image of the screen for the control device 300 to determine whether the screen overlaps with the edge and the specific position of the screen. If there is an overlap, the screen needs to be finely adjusted by the second adjustment mechanism so that the screen does not overlap. The second adjustment mechanism may include a pusher, which is used to apply a pushing force to the screen that is about to overlap so that the screen does not overlap. The control device 300 also determines whether the screen reaches the designated carrier based on the position of the screen or determines whether there is a screen on the carrier based on the image.

[0028] As an optional implementation of the above embodiments, the carrier group 220 includes at least two carriers. In this embodiment, to improve detection efficiency, each carrier group 220 may include at least two carriers, enabling at least two screens to simultaneously detect the same item.

[0029] As an optional implementation of the above embodiments, the number of second robotic arms 140 is the same as the number of carriers on each carrier group 220, and the suction cup components of the second robotic arms 140 can be adjusted in the height direction so that the suction cup components of multiple second robotic arms 140 can be staggered in the height direction. In this embodiment, since multiple screens are simultaneously unloaded at a preset position, multiple second robotic arms 140 are provided to transfer the carriers at the preset position at one time, so as to load the screens to be tested and improve efficiency.

[0030] For example, in some embodiments, to improve detection efficiency, it is necessary to load two or more screens at once. Therefore, to adapt to the detection efficiency, in some embodiments of this application, the second robotic arm 140 has at least two sets, with the at least two sets of second robotic arms 140 spaced apart in a first direction; the second robotic arm 140 picks up the detected screen from the carrier at the detection completion position and transfers it to the transfer platform 170 along a second direction; the second robotic arm 140 includes a transfer suction cup assembly, which is configured to move in the height direction, so that the suction cup assemblies of the at least two sets of second robotic arms 140 can be misaligned in the height direction; wherein the first direction, the second direction, and the height direction are perpendicular to each other. In this embodiment, there are multiple sets of second robotic arms 140, which are arranged at intervals along a first direction and configured to pick up the screens that have been inspected from the carrier at the inspection completion position to the transfer platform 170 along a second direction; and the transfer suction cup assembly on the second robotic arm 140 moves in the height direction so that at least two sets of suction cup assemblies of the second robotic arm 140 can be misaligned in the height direction, so that the second robotic arms 140 do not interfere with each other during the screen transfer process, and can transfer the screens continuously and without interruption, thereby improving the unloading efficiency.

[0031] In some embodiments, the first direction is the left-right direction, and the second direction is the front-back direction; two second robotic arms 140 are arranged at intervals in the left-right direction. The transfer suction cup assemblies on the two robotic arms are movable in the height direction to be staggered in height and to grasp the screen located on the lower side. In addition, in some embodiments, the transfer suction cup assemblies can also be configured to move in the left-right direction.

[0032] As an optional implementation of the above embodiments, Figure 2 and Figure 3 As shown, the AOI inspection device has at least two units, which are arranged at circumferential intervals along the turntable 230. In the technical solution of this application embodiment, there are many AOI inspection items, resulting in a long inspection time; while the Pre-gama inspection time is short. Therefore, having at least two AOI inspection devices allows AOI inspection items to be distributed to AOI inspection devices at different locations, thereby improving inspection efficiency, reducing the idle time rate of Pre-gama inspection, and increasing the inspection cycle time.

[0033] In this embodiment, after the screen to be inspected is loaded at a preset position, it then enters the Pre-gama for inspection, and then sequentially enters the first AOI inspection device and the second AOI inspection device. The first part of the inspection items is completed in the first AOI inspection device, and the second part of the inspection items is completed in the second AOI inspection device, so as to complete the entire AOI inspection item and speed up the inspection cycle.

[0034] In this embodiment, the number of AOI detection devices can be set according to the required cycle time, and the number is not limited to two.

[0035] As an optional implementation of the above embodiments, the detection module 200 further includes a second image acquisition device and a second adjustment mechanism. The second image acquisition device is configured to capture a second image at the loading platform 210, corresponding to the loading platform 210. The second adjustment mechanism is configured to adjust the position of the standby screen on the loading platform 210 according to the second image. The second image acquisition device is used to capture images of the screen to allow the control device 300 to determine whether the screen overlaps with the edge and the specific position of the screen. If there is overlap, the screen needs to be finely adjusted by the second adjustment mechanism to eliminate the overlap. The second adjustment mechanism may include a pusher, which is used to apply a pushing force to the screen that is about to overlap, so that the screen does not overlap. The control device 300 also outputs instructions to the corresponding robot arm according to the position of the screen, so that the corresponding robot arm moves to the position of the screen to grasp the screen.

[0036] In one embodiment, Figure 4 As shown, the loading / unloading module 100 provided in this embodiment includes: Base 110; The material hopper 120 includes an upper material hopper 121, an NG screen lower material hopper 123, and a normal screen lower material hopper 122; the material hopper 120 is disposed next to the base 110; The first robotic arm 130 is movably mounted on the base 110 and is used to pick up the screen to be inspected from the loading bin 121 and onto the loading platform 210. The second robotic arm 140 is movably mounted on the base 110 and is used to pick up the screen that has been inspected from the carrier at the inspection completion position to the transfer platform 170. The third robotic arm 150 is movably mounted on the base 110 and is used to grab the screens on the transfer platform 170 and place them into the NG screen unloading bin 123 or the normal screen unloading bin 122.

[0037] Figure 5As shown, in some technical solutions of this application embodiment, the screen hoppers are all located beside the base 110, so that the hoppers are concentrated around the base 110, saving the transfer path of the robot arm and improving the loading and unloading efficiency; the robot arm includes a first robot arm 130, a second robot arm 140 and a third robot arm 150; the first robot arm 130 is movably disposed on the base 110 and is used to pick up the screen after inspection from the carrier at the inspection completion position to the carrier at the inspection waiting position; the second robot arm 140 is movably disposed on the base 110 and picks up the screen after inspection from the carrier at the inspection completion position to the transfer platform 170, while the third robot arm 150 moves the screen from the transfer platform 170 to the transfer platform 170. The screens that have been inspected on the 0th are picked up and placed into the NG screen unloading bin 123 or the normal screen unloading bin 122. During the unloading process, the screens need to be sorted and unloaded, so the unloading path is uncertain. Therefore, in the technical solution of this application embodiment, the second robot 140 can transfer the screens on the carrier of the inspection position to the transfer platform 170, pick up the inspected screens from the carrier of the inspection completion position, and then use the suction robot to sort the screens on the transfer platform 170 into the NG screen unloading bin 123 and the normal screen unloading bin 122, speeding up the sorting and unloading rhythm, improving the unloading efficiency, and enabling the inspected screens on the inspection device to be quickly unloaded to adapt to the inspection rhythm of the inspection device.

[0038] In some embodiments, the unloading station includes a transfer platform 170 and an unloading bin; the unloading module 100 also includes a third robot arm 150, which is configured to transfer the detected screen on the transfer platform 170 to the unloading bin.

[0039] In the technical solutions of this application embodiment, the robotic arm can be one of a hydraulic robotic arm, a pneumatic robotic arm, an electric robotic arm, or a mechanical robotic arm. The movement of the robotic arm includes linear motion, rotational motion, etc. In some embodiments, the movement of the robotic arm includes linear motion in different directions to accelerate the screen transfer speed.

[0040] As an optional implementation of the above embodiments, the screen detection loading and unloading module 100 is further provided with a third image acquisition device 161, a fourth image acquisition device 162, and a fifth image acquisition device 163. In this embodiment, the image acquisition device may include a CCD device. The third image acquisition device 161 is located in the loading bin 121, the fourth image acquisition device 162 is located in the NG screen unloading bin 123, and the fifth image acquisition device 163 is located in the normal screen unloading bin 122. The third image acquisition device 161, the fourth image acquisition device 162, and the fifth image acquisition device 163 are respectively used to capture images of the screen for the control device 300 to determine whether the screen overlaps and the specific position of the screen; if there is an overlap, the screen needs to be finely adjusted by an adjustment mechanism so that the screen does not overlap. The adjustment mechanism may include a pusher, which is used to apply a pushing force to the screen that is about to overlap so that the screen does not overlap. The control device 300 also outputs instructions to the corresponding robot arm according to the position of the screen so that the corresponding robot arm moves to the position of the screen to grasp the screen. In this embodiment, when the control device 300 determines that the screen overlaps with the edge, it can also issue an alarm.

[0041] As an optional implementation of the above embodiments, the NG screen unloading bin 123 and the normal screen unloading bin 122 are arranged at a distance from each other on the same side of the base 110 in a first direction; the transfer platform 170 is arranged at a distance from the NG screen unloading bin 123 and the normal screen unloading bin 122 in a second direction; the third robot arm 150 is configured to grab the screens on the transfer platform 170 and place them into the NG screen unloading bin 123 or the normal screen unloading bin 122 along the first and second directions. In some technical solutions of the embodiments of this application, when the third robot arm 150 is unloading, it needs to classify and unload the screens according to the instructions of the control device 300. Therefore, the third robot arm 150 needs to be able to move in both the first and second directions so that it can grab the screens on the transfer platform 170 and place them into the NG screen unloading bin 123 or the normal screen unloading bin 122.

[0042] In this embodiment, the unloading suction cup assembly on the third robot 150 can move in the height direction to grab the screen to be unloaded on the transfer platform 170 located on the lower side; after grabbing the screen, the third robot 150 moves along the first direction and the second direction according to the movement path given by the control device 300 to place the screen into the corresponding unloading bin.

[0043] As an optional implementation of the above embodiments, the third robotic arm 150 has at least two sets, and the at least two sets of the third robotic arms 150 are spaced apart in the first direction; the third robotic arm 150 includes a feeding suction cup assembly, which is configured to move in the height direction; wherein, the first direction, the second direction, and the height direction are perpendicular to each other. In some embodiments, the detection device will simultaneously unload multiple or more screens that have been detected. Therefore, in the technical solution of this application embodiment, the third robotic arm 150 is configured in two or more sets and is spaced apart in the first direction (adapting to the spacing direction of the feeding bin, which helps to save the feeding path), so that the third robotic arms 150 can cooperate and unload without interfering with each other, and transfer the screens on the transfer platform 170 in a timely manner.

[0044] As an optional implementation of the above embodiments, Figure 6 As shown, the first robotic arm 130, the second robotic arm 140, and the third robotic arm 150 all include suction cup assemblies. Each suction cup assembly includes a first suction cup group 191 and a second suction cup group 192, with the second suction cup group 192 surrounding the outer side of the first suction cup group 191. In this embodiment, by having the second suction cup group 192 surround the outer side of the first suction cup group 191, the suction cup assembly can adhere to screens of different sizes, improving the compatibility of the loading / unloading module 100. For example, the first suction cup group 191 includes multiple first suction cups, which are connected sequentially along a circular array to form a first enclosed area; the first suction cup group 191 also includes multiple second suction cups, which are connected sequentially along a circular array to form a second enclosed area. The first enclosed area is located within the second enclosed area, meaning the second enclosed area is larger and can adsorb larger screens; the first enclosed area is smaller and can adsorb smaller screens. In addition, when the second suction cup group 192 adsorbs the screen, the first suction cup group 191 can also assist in adsorbing the screen, improving the stability of large screens during the transfer process.

[0045] In some embodiments, the suction cup assembly may further include a third suction cup group 193 disposed around the outside of the second suction cup group 192 to further improve the screen compatibility of the device.

[0046] As an optional implementation of the above embodiments, Figure 4As shown, the loading bin 121, the NG screen unloading bin 123, and the normal screen unloading bin 122 are arranged at intervals along a first direction on the same side of the base 110; or the loading bin 121, the normal screen unloading bin 122, and the NG screen unloading bin 123 are arranged at intervals along a first direction on the same side. In the technical solution of this application embodiment, the loading bin 121 and the unloading bin are arranged at intervals along a first direction on the same side, so that loading and unloading are located on the same side of the base 110, thereby reasonably arranging the first robot arm 130, the third robot arm 150, and the second robot arm 140 to load from the same side and unload from the same side, improving space utilization and helping to rationally plan the transfer paths of the first robot arm 130, the third robot arm 150, and the second robot arm 140. In addition, along the first direction, the sequence is loading, unloading of NG screens, and unloading of normal screens (or loading, unloading of NG screens, and suction of normal screens), so that the transfer path of the third robot 150 does not overlap with the transfer path of the first robot 130, thereby improving the screen transfer efficiency.

[0047] As an optional implementation of the above embodiments, the NG screen unloading bin 123 includes at least two bins, which are used to place screens with different defect types. In the technical solution of this application embodiment, NG screens have different defect types, therefore at least two NG screen unloading bins 123 are set up to classify and store NG screens. For example, screens with dot defects are placed in one NG screen unloading bin 123, and screens with line and image defects are placed in another NG screen unloading bin 123.

[0048] In this embodiment, the third robotic arm 150 transfers the screens on the transfer platform 170 to different NG screen unloading bins 123 according to the instructions of the control device 300.

[0049] As an optional implementation of the above embodiments, the loading / unloading module 100 further includes a gripping robot, which is movably disposed in the hopper and used to grip empty pallets. In the technical solution of this application embodiment, each hopper contains empty pallets, which are used to support screens. In some cases, when the utilization rate of empty pallets in a certain hopper is high, while the idle rate of empty pallets in other hoppers is high, the gripping robot can be used to grip the idle empty pallets and move them to the hopper with the higher utilization rate.

[0050] In this embodiment, each hopper has a transfer device for moving pallets. The transfer device may include a roller assembly. Empty pallets are placed on the transfer device. When the utilization rate of empty pallets in a certain hopper is high, empty pallets from transfer devices in other hoppers can be transferred to that hopper using a gripping robot to increase the number of empty pallets on the transfer devices in that hopper.

[0051] In some embodiments of this application, the transfer device has two layers in the height direction. A designated position is provided on the first layer (upper layer).

[0052] For the loading hopper 121, at a designated location, the first robotic arm 130 is used to grab the screens on the pallets located on the higher upper layer. An external transport vehicle transports the stacked screens (each screen carried by a pallet) to the second layer (lower layer), and then through the roller assembly mechanism of the lower layer to the corresponding position of the lifting mechanism, which lifts the pallets one by one to the designated position; subsequently, the empty pallets are transported from the first layer to the loading hopper 121.

[0053] For the unloading hopper, the screens that have been inspected are transferred to an empty pallet located at a designated position on a higher upper layer. The empty pallet is transported to the designated position from the outside by the roller assembly mechanism on the first layer; after the inspected screens are placed on the empty pallet, they are transferred to the second layer by a lifting mechanism for stacking, and then transported out of the unloading hopper by the roller assembly mechanism on the lower layer.

[0054] In one embodiment, the lifting mechanism is equipped with a gripper for gripping the tray.

[0055] In the screen inspection device 10 of this application embodiment, when performing screen inspection, the first robot arm 130 transfers the screen to be inspected from the loading bin 121 to the loading platform 210, and then the transfer mechanism 180 transfers it to the carrier group 220 at the preset position of the turntable 230. The turntable 230 rotates, so that the screen passes through the pre-gama inspection equipment and the AOI inspection equipment in sequence. After the turntable 230 completes one revolution, the screen inspection is completed and it returns to the preset position. At this time, the second robot arm 140 transfers the inspected screen to the transfer platform 170. Subsequently, the carrier group 220 at the preset position is empty, and the transfer mechanism 180 transfers the screens on the loading platform 210 to the carrier group 220 at the preset position of the turntable 230 to continue the next batch of carrier inspection. The screens transferred to the transfer platform are then transferred to the corresponding unloading bin by the third robot arm 150 according to the inspection results, thus completing the screen inspection. During the inspection process, the CCD device is used to determine the position of the screen and whether it overlaps with the edge. The screen is adjusted in a timely manner through the adjustment mechanism, and the position of the screen is communicated to the robotic arm.

[0056] AOI stands for Automated Optical Inspection. Pre-gamma correction refers to gamma correction processing performed before the image signal enters the final driving circuit of the display panel. Its core function is to pre-adjust the grayscale / brightness mapping relationship of the image signal to match the non-linear brightness perception characteristics of the human eye and the electro-optical response curve of the display panel, ultimately achieving more accurate color reproduction, smoother grayscale transitions, and a display effect more consistent with human vision. The above descriptions are merely optional embodiments of this application and do not limit the patent scope of this application. Any equivalent structural transformations made based on the concept of this application and the content of this specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
