[0034] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It should also be noted that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0035] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0036] In the process of producing display panels, the curved side of the display panel usually has defects such as bubbles or cracks, so it is necessary to detect the edge of the curved side of the display panel, and the speed of conveying the display panel will affect the quality and efficiency of the inspection. If the conveying is too fast, a clear image cannot be collected, and if the conveying is too slow, the inspection efficiency is low. An embodiment of the present invention provides a display panel inspection device, which ensures the inspection quality and improves the inspection efficiency.

[0037] like Figure 1 and Figure 2 As shown, the display panel detection device provided by the embodiment of the present invention comprises: a workbench 1, two carrier boards 2 and two sets of driving devices;

[0038] The workbench 1 has a plurality of workstations, which include a receiving position 3, an optical detection position 4 and a discharge position 5 which are arranged in sequence, and the optical detection position 4 is located in the transport channel between the receiving position 3 and the discharge position 5;

[0039] Two sets of driving devices are relatively installed on the workbench 1, and multiple workstations and transportation channels are located on the workbench surface between the two sets of driving devices;

[0040] The two sets of driving devices are connected to the two carriers 2 in a one-to-one correspondence. The driving devices are suitable for driving the carriers 2 to move back and forth between the receiving position 3 and the unloading position 5 along the transportation channel. The two carriers 2 alternately run to the unloading position 5 and alternately return to the receiving position 3.

[0041] In the display panel inspection device of this embodiment, the carrier plate is used to receive the display panel to be inspected, hereinafter referred to as the panel to be inspected. The carrier plate receives the panel to be inspected at the receiving position and unloads the panel to be inspected at the unloading position. The optical inspection position is located in the transportation channel between the receiving position and the unloading position. The carrier plate passes through the optical inspection position during the process of moving from the receiving position to the unloading position. The two carrier plates alternately pass through the optical inspection position, so that the cycle time of the panel to be inspected passing through the optical inspection position is shortened, which effectively improves the inspection efficiency.

[0042] In some examples, the carrier plate 2 can reciprocate along a straight line between the receiving position 3 and the unloading position 5;

[0043] Each carrier plate 2 has a symmetry axis extending along its moving direction, and the symmetry axis is parallel to the horizontal surface of the workbench. The symmetry axes of the two carrier plates 2 are located in the same vertical plane, and the two sets of driving devices are symmetrically arranged about the vertical plane where the symmetry axes of the two carrier plates 2 are located.

[0044] In this embodiment, it is preferred that the connecting line of the material receiving position, the optical detection position and the material unloading position is located on a straight line, and the projection of the transport channel on the horizontal surface of the workbench is a rectangular structure.

[0045] The carrier plate can reciprocate along a straight line between the material receiving position and the material unloading position, and the symmetry axes of the two carrier plates are located in the same vertical plane. The two carrier plates can reciprocate on the same straight line between the material receiving position and the material unloading position, thereby ensuring that the two carrier plates can accurately pass through the optical detection position to ensure the detection effect.

[0046] In some examples, the driving device includes a lifting driving mechanism 6 connected to the bottom of the carrier plate 2 and a horizontal moving mechanism 7 connected to the lifting driving mechanism, wherein

[0047] The lifting drive mechanism is suitable for driving the carrier plate 2 to move between a first height and a second height in a direction perpendicular to the workbench 1, and the first height is greater than the second height;

[0048] The horizontal moving mechanism is suitable for driving the carrier plate 2 to move from the material receiving position 3 to the material discharging position 5 at a first height and is suitable for driving the carrier plate 2 to move from the material discharging position 5 to the material receiving position 3 at a second height.

[0049] Since the symmetry axes of the two carriers are located in the same vertical plane, and the projections of the moving trajectories of the two carriers on the horizontal surface of the workbench overlap, the two carriers need to move staggered. The driving device includes a lifting driving mechanism and a horizontal moving mechanism, which can move the carrier in the vertical direction (such as the Z axis) and the horizontal direction (such as the X axis), so that the carrier moves from the material receiving position to the material unloading position at a first height, and moves from the material unloading position to the material receiving position at a second height, and the first height is greater than the second height, thereby realizing the staggered operation of the two carriers, and when the carrier carries the panel to be inspected, it passes through the optical detection position at the first height, ensuring that the panel to be inspected is not blocked at the optical detection position, thereby realizing the detection of the panel to be inspected.

[0050] In some examples, the lifting drive mechanism is one of a screw mechanism, a telescopic motor, a cylinder, and a hydraulic cylinder, and the bottom of the carrier plate is connected to the output end of the lifting drive mechanism.

[0051] In this embodiment, the lifting drive mechanism is preferably a telescopic motor, the end of the lead screw output shaft of the telescopic motor is connected to the bottom surface of the carrier plate, and the telescopic motor drives the carrier plate to rise and fall between the first height and the second height to achieve the additional movement of the carrier plate in the Z-axis direction. The telescopic motor can be a servo motor or a stepper motor.

[0052] In some examples, the horizontal moving mechanism includes a guide rail installed on the workbench 1, a sliding block slidingly matched with the guide rail, a horizontal lead screw and a driving motor driving the horizontal lead screw to rotate. The sliding block is threadedly sleeved on the horizontal lead screw, and the lifting drive mechanism is installed on the sliding block.

[0053] In this embodiment, the driving motor works to drive the horizontal lead screw to rotate, thereby driving the sliding block to move relative to the guide rail, for example, the sliding block moves along the X-axis direction; preferably, the driving lifting mechanism is installed on the sliding block, so that under the action of the horizontal moving mechanism, the carrier plate can be moved in the X-axis direction. The driving motor can be a servo motor or a stepping motor.

[0054] In some examples, the optical inspection position 4 is provided with an image acquisition device, which includes two groups of image acquisition modules 8. The two groups of image acquisition modules 8 are symmetrically arranged about the vertical plane where the symmetry axes of the two carriers are located. The image acquisition modules 8 include at least two linear array cameras and detection light sources arranged corresponding to the linear array cameras. The linear array cameras are suitable for detecting the curved side of the panel to be inspected.

[0055] In this embodiment, the number of line array cameras in the image acquisition module is preferably 3, the 3 line array cameras are arranged in parallel and at intervals, and the line connecting the 3 line array cameras is located in a plane or an arc surface, and the plane or the arc surface is inclined relative to the vertical direction;

[0056] Preferably, the image acquisition module further includes an area array camera, and the panel camera is suitable for detecting the plane portion of the panel to be inspected.

[0057] An embodiment of the present invention further provides a display panel detection system, comprising the above-mentioned display panel detection device and a controller, wherein the controller is electrically connected to a driving device and an image acquisition device in the display panel detection device.

[0058] For example, the controller is electrically connected to the telescopic motor, the driving motor, and the detection camera (eg, a linear array camera, an area array camera) to control the telescopic motor and the driving motor to work, and to control the detection camera to collect images of the panel to be inspected.

[0059] The display panel detection device provided in an embodiment of the present invention can detect whether there is a display panel on each carrier by configuring infrared sensors at each workstation, and the controller receives the signals of each infrared sensor, and generates control signals corresponding to the telescopic motor, driving electrode and detection camera according to the signals of each infrared sensor.

[0060] Based on the display panel detection device introduced in the above embodiment, a detection method corresponding to the detection device is further introduced below.

[0061] An embodiment of the present invention further provides a display panel detection method, comprising:

[0062] A carrier plate 2 is moved to the receiving position 3, and a carrier plate 2 performs a round of reciprocating motion after receiving the inspection panel;

[0063] When one carrier plate 2 moves out of the material receiving position 3, another carrier plate 2 is moved to the material receiving position 3;

[0064] The other carrier plate 2 performs a round of reciprocating motion after receiving the inspection panel. When the other carrier plate 2 returns to the receiving position 3, the first carrier plate 2 has entered the next round of reciprocating motion;

[0065] Among them, one round of reciprocating motion includes any carrier plate 2 moving from the receiving position 3 to the unloading position 5, unloading the inspected panel at the unloading position 5, and returning from the unloading position 5 to the receiving position 3;

[0066] During the process of any carrier plate 2 moving from the receiving position 3 to the unloading position 5, the image acquisition device located at the optical detection position 4 acquires the image of the panel to be inspected, generates the detection result according to the acquired image, and determines whether there is a defective area in the panel to be inspected based on the detection result.

[0067] Among them, the two carriers alternately pass through the optical inspection position and cyclically transport the panels to be inspected, so that the TT of the panels to be inspected passing through the optical inspection position is shortened, which greatly improves the inspection efficiency.

[0068] In some examples, the transport channel of the display panel inspection device has an inspection start point and an inspection completion point, and the optical inspection position 4 is located between the inspection start point and the inspection completion point;

[0069] Any carrier plate 2 moves from the material receiving position 3 to the detection trigger point at a first speed V1, moves at a uniform speed from the detection starting point to the detection completion point at a second speed V2, moves from the detection completion point to the unloading position 5 at a third speed V3, and moves from the unloading position 5 to the material receiving position 3 at a fourth speed V4. The second speed V2 is smaller than the first speed V1, the third speed V3 and the fourth speed V4.

[0070] The carrier carrying the panel to be inspected moves from the receiving position to the detection trigger point at a first speed V1, decreases from the first speed V1 to the second speed V2, passes through the optical detection area at a uniform speed at the second speed V2, then speeds up to the third speed V3 to move to the unloading position, and after unloading the inspected panels at the unloading position, adjusts the speed to the fourth speed V4 to return from the unloading position to the receiving position. The carrier passes through the optical detection area at a low and uniform speed to ensure that the image acquisition device in the optical detection area can capture a clear image; the moving speed of the carrier is controlled in a round of reciprocating motion from the receiving position to the unloading position and then back to the receiving position; through the reasonable setting of V1, V2, V3 and V4 by the designer, the two carriers can be staggered to stably transport the panels to be inspected, so that the display panel detection device can cooperate well with the upstream feeding device.

[0071] In some examples, when one of the two carrier plates 2 of the display panel detection device is located at the receiving position 3 , the other carrier plate 2 is located at the unloading position 5 .

[0072] The display panel detection device cooperates with the upstream feeding device to work, and the pick-and-place mechanism of the upstream feeding device puts the panel to be inspected on the carrier plate located at the receiving position.

[0073] For example, the two carriers are the first carrier and the second carrier, and the process of the two carriers conveying the panel to be inspected can be, for example, both carriers are in the process of moving from the receiving position to the unloading position, and the first carrier receives the panel to be inspected before the second carrier; then the first carrier turns back from the unloading position first, and the second carrier is still in the process of moving from the receiving position to the unloading position; after the first carrier turns back for a period of time, the second carrier also turns back; then both carriers are in the process of moving from the receiving position to the unloading position. For example, during a round of reciprocating motion of the first carrier and the second carrier, the time for the pick-and-place mechanism to place the panel to be inspected on the first carrier is t1, and the time for the pick-and-place mechanism to place the panel to be inspected on the second carrier is t2; during the next round of reciprocating motion of the first carrier and the second carrier, the time for the pick-and-place mechanism to place the panel to be inspected on the first carrier is t3, and the time for the pick-and-place mechanism to place the panel to be inspected on the second carrier is t4, and the interval between t1 and t2 is less than the interval between t2 and t3, resulting in uneven TT of the pick-and-place mechanism.

[0074] In this embodiment, when one of the two carrier plates is located at the material receiving position, the other carrier plate is located at the material unloading position. The alternating operation of the two carrier plates shortens the TT of the optical sampling device by half.

[0075] According to the time the carrier stays at the receiving position and the unloading position, and the distance between the receiving position and the unloading position, it is preferred that V1 and V3 are the same, V1 is greater than V4, and V4 is greater than V2. A suitable speed value is selected within this speed range so that when one of the two carriers is at the receiving position, the other carrier is at the unloading position, so that the upstream pick-up and place mechanism can operate at evenly spaced time intervals.

[0076] In some examples, any carrier plate 2 moves from the receiving position 3 to the unloading position 5 at a first height from the workbench 1 of the display panel detection device, and any carrier plate 2 moves from the unloading position 5 to the receiving position 3 at a second height from the workbench 1, and the first height is greater than the second height.

[0077] The two image acquisition modules are symmetrically arranged about the vertical plane where the axes of the two carriers are located. The double carriers are staggered at the first height and the second height to transport the panel to be inspected, so that the two carriers can pass through the optical inspection position with the same moving path. In this way, neither carrier will deviate toward one of the two image acquisition modules when passing through the optical inspection position, thereby ensuring that the panel to be inspected on any carrier can be accurately and clearly imaged by the image acquisition device at the optical inspection position.

[0078] According to the above embodiment, the display panel detection method can be executed under the control of the controller in the above display panel detection system.

[0079] In addition, an embodiment of the present invention further provides a storage medium, the storage medium includes a stored program, wherein the program executes any of the above-mentioned display panel detection methods. The storage medium includes: a U disk, a read-only memory (ROM), a random access memory (RAM), a mobile hard disk, a magnetic disk or an optical disk, and other media that can store program codes.

[0080] An embodiment of the present invention further provides a processor, and the processor is used to run a program, wherein the program executes any one of the above-mentioned display panel detection methods when running.
