Description

Technical Field

[0001] The invention relates to the technical field of display screen testing, and in particular to an automatic testing method and device for a welded LCD display screen. Background Art

[0002] At present, there are two main physical interface forms of LCD display screens, one is the connector-type gold finger interface, and the other is the soldering-type gold finger interface. The connector-type gold finger interface is installed on the PCB board through the connector for testing, while the soldering-type gold finger interface cannot be installed on the connector for testing. Compared with the connector-type display screen, the testing of the soldering-type display screen is relatively complicated. Workers need to align the gold finger of the display screen with the PCB pad, and then press the gold finger by controlling the pressure head to make the gold finger and the pad fully contact before entering the relevant functional test.

[0003] The above-mentioned prior art solutions have the following defects:

[0004] Through manual alignment, it is easy for the gold finger and the pad to be offset, misaligned or have insufficient contact. In serious cases, the screen may burn in, which greatly affects production efficiency. Summary of the invention

[0005] In order to solve the problems of poor alignment accuracy and low production efficiency in the existing welding type LCD display screen test, the present application provides a welding type LCD display screen automatic testing method and device.

[0006] The above-mentioned invention objective of the present application is achieved through the following technical solutions:

[0007] A method for automatically testing a welded LCD display screen, the method comprising:

[0008] Obtain the display screen adsorption instruction and generate the gold finger pressing instruction. After obtaining the gold finger pressing feedback, generate the display screen test instruction;

[0009] Acquire basic display screen data according to the display screen test instruction, and perform basic data test instruction on the basic display screen data to obtain basic test results, wherein the basic test results include test pass and test abnormality;

[0010] When the basic test result is that the test is abnormal, a power cut-off instruction is triggered; when the basic test result is that the test is passed, a screen display picture acquisition instruction is triggered, and after the screen display picture is acquired, the screen display picture is detected to obtain a picture detection result;

[0011] When the basic test result and the screen detection result are obtained, a display screen replacement instruction is triggered.

[0012] By adopting the above technical solution, by triggering the display screen adsorption instruction, the gold finger pressing instruction and the display screen replacement instruction, etc., the corresponding equipment can be controlled to realize the automatic alignment of the gold finger and the PCB adapter board when testing the welded LCD display screen, thereby improving the accuracy and efficiency of the test, and then improving the production efficiency; by detecting the basic data test during the screen test, the power supply can be turned off in time when the voltage and current are detected to be abnormal, thereby reducing the risk of LCD burnout; further, by collecting the display screen, the display status of the display screen can be judged by image comparison, thereby improving the accuracy of the detection.

[0013] In a preferred example, the present application can be further configured as follows: the generating of the gold finger pressing instruction, after obtaining the gold finger pressing feedback, generates the display screen test instruction, specifically including:

[0014] Acquire a display screen adsorption image, acquire real-time gold finger position data according to the display screen adsorption image, and acquire gold finger coordinate data of the connection point from the gold finger position data;

[0015] Acquire pad position data, acquire connection point coordinate data from the pad position data, and trigger the gold finger pressing instruction when the gold finger coordinate data coincides with the corresponding connection point coordinate data;

[0016] The gold finger pressing image data is acquired, the gold finger pressing image data is verified, and the gold finger pressing feedback is triggered after the verification passes.

[0017] By adopting the above technical solution, since there may be errors in the placement of each LCD display screen to be tested, it is easy to cause the relative position of the display screen and the adsorption device to shift when the display screen is adsorbed. Therefore, by obtaining the adsorption image of the display screen and obtaining the gold finger position data in real time, the position of the display screen can be corrected by visual detection during the process of adsorbing and moving the display screen to the pad position, thereby improving the accuracy of the display screen test.

[0018] In a preferred example, the present application can be further configured as follows: when the basic test result is that the test is passed, a screen display picture acquisition instruction is triggered, and after the screen display picture is acquired, the screen display picture is detected to obtain a picture detection result, which specifically includes:

[0019] Acquire a set of detection screen images, display the corresponding screens to be detected one by one, and acquire the screen display screen corresponding to each of the screens to be detected, wherein the screen display screen refers to an image obtained after the screen to be detected is photographed and displayed on an LCD display screen, and the number of the screen display screens corresponding to each of the screens to be detected is greater than one;

[0020] All the screen display pictures of each picture to be detected are detected to obtain the picture detection result.

[0021] By adopting the above-mentioned technical scheme, by pre-setting the detection screen image set, it is possible to verify whether the display capability of the display screen is normal according to the display characteristics of the display screen. At the same time, after the display screen displays the corresponding screen to be detected, by taking a number of screen display images displayed on the display screen after each screen to be detected is displayed on the display screen, the accuracy of the detection can be improved.

[0022] In a preferred example, the present application may be further configured as follows: detecting all the screen display images of each of the images to be detected to obtain the image detection result specifically includes:

[0023] Calculating the picture similarity between the screen display pictures of each group of the pictures to be detected, and judging the picture similarity with the corresponding similarity threshold to obtain a judgment result;

[0024] If the judgment result is that the screen similarity is higher than the similarity threshold, each of the screen display images is compared with a pre-stored reference comparison image, and the image comparison result is used as the screen detection result;

[0025] If the judgment result is that the picture similarity is lower than the similarity threshold, a screen display picture is randomly selected to be compared with a pre-stored reference comparison image, and the image comparison result is used as the picture detection result.

[0026] By adopting the above technical solution, by first performing the picture similarity between the screen display pictures corresponding to each picture to be detected, it is possible to first determine whether there is an abnormality in the picture display during the continuous display of the picture to be detected. If there is an abnormality, that is, the picture similarity is higher than the similarity threshold, then the picture detection result is performed. If there is no abnormality, that is, the picture similarity is lower than the similarity threshold, a screen display picture is randomly selected for detection, which can ensure the accuracy and efficiency of the detection while judging the stability of the display screen display.

[0027] In a preferred example, the present application can be further configured as follows: the screen detection result includes a normal detection and an abnormal detection, and when the basic test result and the screen detection result are obtained, a display screen replacement instruction is triggered, specifically including:

[0028] When the image detection result is abnormal, obtaining abnormal image data from the image comparison result;

[0029] After the test abnormality and / or the abnormal image data are stored in a corresponding database, the display screen replacement instruction is triggered.

[0030] By adopting the above technical solution, when an abnormality is detected, the abnormal data is stored in time, and then the display screen is replaced. This makes it convenient to centrally analyze and determine the cause of the abnormality after the batch detection of the display screen is completed, which is helpful for the investigation and optimization of abnormal situations.

[0054] The present application is further described in detail below in conjunction with the accompanying drawings.

[0055] In one embodiment, if Figure 1 As shown, the present application discloses a method for automatically testing a welded LCD display screen, which specifically includes the following steps:

[0056] S10: Obtain a display screen adsorption instruction and generate a gold finger pressing instruction. After obtaining the gold finger pressing feedback, generate a display screen test instruction.

[0057] In this embodiment, the display screen adsorption instruction refers to an instruction for controlling the corresponding device to adsorb the display screen to be tested. The gold finger pressing instruction refers to an instruction for pressing the gold finger of the LCD display screen onto the corresponding pad.

[0058] Specifically, Figure 2 As shown, the detection device includes a test host, a PCB adapter board, a voltage detection module, a current detection module, a temperature and humidity sensor module, a manipulator control module, a pressure head control module, a camera module, an LCD fixed block and an insulating pressure head.

[0059] The PCB adapter board is fixed to the acrylic board by threaded fasteners, and a PCB pad is fixed on the PCB adapter board for connecting with the gold finger of the LCD display screen, so as to realize the data interaction between the test host and the display screen during the test of the display screen. The voltage detection module and the current detection module are installed on one side of the PCB adapter board, so as to enable the test host to obtain the voltage and current of the LCD display screen being tested. At the same time, it also includes a manipulator, which is provided with an adsorption device and a clamping device, and the manipulator is controlled by the manipulator control module and the pressure head control module.

[0060] Furthermore, after obtaining the display screen adsorption instruction, the display screen adsorption instruction is sent to the manipulator control module to control the adsorption device of the manipulator to adsorb the corresponding display screen for detection. After the adsorption device adsorbs the display screen, the manipulator is controlled to move the display screen to the PCB adapter board, and a gold finger pressing instruction is generated and sent to the pressure head control module to control the pressure head to press the gold finger of the display screen with the pad on the PCB adapter board. After the gold finger is pressed with the pad, a gold finger pressing feedback is generated, and after obtaining the gold finger pressing feedback, the display screen test instruction is generated to test the display screen.

[0061] S20: acquiring basic display screen data according to the display screen test instruction, and performing basic data test instructions on the basic display screen data to obtain basic test results, wherein the basic test results include test pass and test abnormality.

[0062] Specifically, during the testing of the display screen, the voltage and current of the display screen are detected in real time through the voltage detection module and the current detection module on the PCB adapter board. At the same time, the indoor temperature and humidity are obtained in real time through the indoor temperature and humidity sensor to obtain the basic data of the display screen.

[0063] Furthermore, after acquiring the real-time basic data of the display screen, the basic data of the display screen is tested in real time to obtain the basic test result.

[0064] S30: When the basic test result is a test abnormality, a power cut-off instruction is triggered; when the basic test result is a test pass, a screen display picture acquisition instruction is triggered; after the screen display picture is acquired, the screen display picture is detected to obtain a picture detection result.

[0065] In this embodiment, the display screen image acquisition instruction refers to an instruction for controlling the camera module to capture the display image of the display screen being tested.

[0066] Specifically, when the voltage and / or current in the basic test result is abnormal, that is, the basic test result is a test abnormality, the power cut-off instruction is triggered. When the test passes, the screen display picture acquisition instruction is sent to the camera module to obtain the picture displayed on the display screen, that is, the screen display picture.

[0067] Furthermore, after the corresponding screen display picture is acquired, the screen display picture is detected to determine whether the display effect of the display screen meets expectations, thereby obtaining the picture detection result.

[0068] S40: When the basic test results and the screen detection results are obtained, a display screen replacement instruction is triggered.

[0069] Specifically, after the image detection result is obtained, that is, the detection of the display screen is completed, the display screen replacement instruction is triggered to control the pressure head to release, and control the adsorption device to transfer the display screen that has completed the detection, and adsorb the next display screen for detection.

[0070] In this embodiment, by triggering the display screen adsorption instruction, the gold finger pressing instruction and the display screen replacement instruction, etc., the corresponding equipment can be controlled to realize the automatic alignment of the gold finger and the PCB adapter board when testing the welded LCD display screen, thereby improving the accuracy and efficiency of the test, and further improving the production efficiency; by detecting the basic data test during the screen test, the power supply can be turned off in time when the voltage and current are detected to be abnormal, thereby reducing the risk of LCD burnout; further, by collecting the display screen, the display status of the display screen can be judged by image comparison, thereby improving the accuracy of the detection.

[0071] In one embodiment, if Figure 3 As shown, in step S10, a gold finger pressing instruction is generated, and after the gold finger pressing feedback is obtained, a display screen test instruction is generated, which specifically includes:

[0072] S11: Acquire a display screen adsorption image, acquire real-time gold finger position data according to the display screen adsorption image, and acquire gold finger coordinate data of the connection point from the gold finger position data.

[0073] In this embodiment, the display screen adsorption image refers to an image captured when the display screen to be detected is adsorbed by the adsorption device. The gold finger position data refers to the relative position of the gold finger on the display screen and the pad on the PCB board.

[0074] Specifically, by installing a camera device on the adsorption device, or utilizing a camera module, during the process in which the adsorption device adsorbs the display screen and transfers it to the PCB adapter board, the position of the gold finger can be identified from the adsorption image of the display screen in real time according to the current installation position and shooting angle of the camera, as the gold finger position data.

[0075] Furthermore, since the position of the PCB adapter board is relatively fixed, a spatial coordinate system is constructed based on the position of the pad on the PCB adapter board, and the coordinates of the connection point between the gold finger and the pad in the spatial coordinate system are obtained according to the gold finger position data as the gold finger coordinate data.

[0076] S12: Obtain pad position data, obtain connection point coordinate data from the pad position data, and trigger a gold finger pressing instruction when the gold finger coordinate data coincides with the corresponding connection point coordinate data.

[0077] Specifically, the installation position of the pad is obtained from the position of the PCB adapter board as the pad position data, and the position of the connection point where the gold finger contacts the pad in the coordinate system is obtained as the connection point coordinate data.

[0078] Further, when it is determined from the gold finger coordinate data and the connection point coordinate data that the directions of the gold finger and the pad coincide with each other in the projection position, the gold finger pressing instruction is triggered.

[0079] S13: Acquire the gold finger pressing image data, verify the gold finger pressing image data, and trigger the gold finger pressing feedback after the verification passes.

[0080] In this embodiment, the gold finger pressing image data refers to an image captured when the gold finger is pressed onto the pad by the pressing head.

[0081] Specifically, after the pressure head presses the gold finger onto the pad, the gold finger pressing image data is captured and verified. If the verification fails, an image of the misaligned contact part between the pad and the gold finger is obtained, and the horizontal and vertical offsets are calculated from the image. The correction instruction is triggered according to the offset to control the pressure head to release and adjust the position of the gold finger according to the offset, and the gold finger pressing image data is obtained again; if the verification passes, the gold finger pressing feedback is triggered, and the test host can start testing the display screen.

[0082] In one embodiment, if Figure 4 As shown, in step S30, that is, when the basic test result is that the test is passed, the screen display picture acquisition instruction is triggered, and after the screen display picture is acquired, the screen display picture is detected to obtain the picture detection result, which specifically includes:

[0083] S31: Obtain a set of detection screen images, display the corresponding screens to be detected one by one, and obtain a screen display screen corresponding to each screen to be detected, wherein the screen display screen refers to an image obtained after shooting the screen to be detected and displaying it on an LCD display screen, and the number of screen display screens corresponding to each screen to be detected is greater than one.

[0084] Specifically, several images to be detected are obtained in advance according to the content to be tested on the display screen, such as the color display capability, to form a detection image set. Further, the images to be detected in the detection image set are sent to the display screen one by one, and the display screen is controlled to display the images to be detected. At the same time, each time a picture to be detected is displayed on the display screen, several pictures to be detected are taken by the camera module as a group of screen display pictures. In this embodiment, three pictures are taken.

[0085] S32: Detect all screen display images of each image to be detected to obtain an image detection result.

[0086] Specifically, a screen display picture corresponding to each picture to be detected is detected to determine the display effect of the display screen and obtain the picture detection result.

[0087] In one embodiment, if Figure 5 As shown, in step S32, all screen display images of each image to be detected are detected to obtain the image detection result, which specifically includes:

[0088] S321: Calculate the screen similarity between the screen display screens of each group of screens to be detected, and judge the screen similarity with the corresponding similarity threshold to obtain a judgment result.

[0089] Specifically, when detecting the screen display images, the image similarity between the screen display images in each group of images to be detected is calculated, that is, when the display screen displays the image to be detected, the image similarity is judged against the similarity threshold, and whether the image displayed on the display screen is stable is obtained from the judgment result.

[0090] S322: If the judgment result is that the screen similarity is higher than the similarity threshold, each screen display screen is compared with a pre-stored reference comparison image, and the image comparison result is used as the screen detection result.

[0091] Specifically, if the judgment result is that the picture similarity is higher than the similarity threshold, it means that the display screen may have unstable display when displaying the picture to be detected, resulting in a large difference between the screen display pictures taken. Therefore, each screen display picture in the group is compared with the pre-stored reference comparison image, so as to detect the display effect of the display screen according to the image comparison result as the picture detection result.

[0092] S323: If the judgment result is that the picture similarity is lower than the similarity threshold, a screen display picture is randomly selected for comparison with a pre-stored reference comparison image, and the image comparison result is used as the picture detection result.

[0093] Specifically, if the judgment result is that the picture similarity is lower than the similarity threshold, it means that the difference between the screen display pictures of this group is not large, then one of them is randomly selected for comparison with the reference comparison image, so as to detect the display effect of the display screen according to the image comparison result as the picture detection result.

[0094] In one embodiment, if Figure 6 As shown, in step S40, that is, the screen detection result includes normal detection and abnormal detection, when the basic test result and the screen detection result are obtained, the display screen replacement instruction is triggered, which specifically includes:

[0095] S41: When the image detection result is abnormal, abnormal image data is obtained from the image comparison result.

[0096] Specifically, if a detection abnormality is obtained from the screen detection result, it means that the display effect of the display screen is abnormal, and the screen display picture corresponding to the detection abnormality is obtained as the abnormal image data.

[0097] S42: After storing the test abnormality and / or abnormal image data into the corresponding database, triggering a display screen replacement instruction.

[0098] Specifically, during the process of testing the display screen, if abnormal test data is obtained, including test abnormalities and abnormal image data, the abnormal data of the test abnormality and the abnormal image data marked as abnormal are stored in the corresponding database, and after being associated with the unique identifier of the display screen, a display screen replacement instruction is triggered to control the adsorption device to replace the next display screen for testing.

[0099] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
