[0061] The present utility model provides a detection device and a detection method, which can perform on - line detection of screen defect features, greatly improving the working efficiency of screen defect detection and display operations.

[0062] It should be noted here that the detection device and the detection method provided by the present utility model can be used for defect detection of second - hand mobile phone screens. However, it is not limited to this. The detection device and the detection method can also be used for photographing and detecting mobile phones during the production process, new mobile phones before being sold / used, or any products in other scenarios. For the convenience of description and understanding, the present utility model takes the specific application scenario of defect detection of second - hand mobile phone screens as an example for specific description.

[0063] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0064] Please refer to Figures 1 to 6 , the embodiments of the present utility model provide a detection device capable of detecting defects in the screen of an electronic device. The detection device includes a conveying module, a photographing module 2, and a processing module. Among them: The conveying module at least includes a starting feeding position 11, a detection position 14, and an end discharging position 15 on the conveying line. The starting feeding position 11 can receive the target product to be detected delivered from a logistics line or other means. The detection position 14 can temporarily store the target product for the photographing module 2 to photograph the target product and for the target product to complete the detection. The end discharging position 15 can output the target product from the conveying line (when the end discharging position 15 is docked with the logistics line, the target product can be output from the conveying line to the logistics line); The photographing module 2 is located above the detection position 14 and can photograph the screen of the target product to obtain a product picture; The processing module can analyze the product picture to obtain the detection result of the target product. It can be seen that the detection device provided by the embodiments of the present utility model is a single device, which can perform operations such as receiving, transferring, outputting, photographing, and analyzing the target product through a single device, achieving the purpose of online detection of screen defects. It occupies a small space, has no requirements for the site environment, and is conducive to realizing automated online detection and improving production capacity.

[0065] Specifically, when the detection device is used to detect defects in the screen of an electronic device, the analysis process of the processing module at least includes: analyzing the product picture, extracting defect features and detecting them to obtain any one or several of the specific information such as the type, position, length, width, area, and shape of each defect; Further, the quality of the target product can also be determined according to the detection result and the established standard. Among them, the established standard can be a determination standard uniformly formulated and implemented within the enterprise (or a standard obtained by other means). According to this standard, quantifiable data statistics can be performed on the screen defect features, and the unified definition of the product quality can be completed, so as to support streamlined online operations and improve production capacity. However, it is not limited to this. In specific implementation, the specific analysis process of the processing module can be specifically designed according to the actual situation as long as it can meet the detection requirements.

[0066] In some embodiments, the processing module can be communicatively connected to the target product entering the detection device and can control the target product to turn the screen black, turn the screen on, switch the screen background image, adjust the screen display brightness, etc.; the detection results include screen defect information of the target product when the screen is black, on, and displaying different screen background images, and the screen defect information includes any one or several of defect type, defect location, defect size, defect area, and defect shape. Among them, the defect type includes scratches, cracks, broken screens, stains, display defects, etc.

[0067] In some embodiments, the above detection device further includes a barcode scanning module, and the above conveying module further includes a barcode scanning input position 12. Among them: The barcode scanning input position 12 is located between the starting material loading position 11 and the detection position 14; the barcode scanning module is located near the barcode scanning input position 12 and can scan the target product to obtain product information when the target product is conveyed to the barcode scanning input position 12. The product information includes serial number information, as well as model information and / or size information. Further, the barcode scanning module is signal-connected to the processing module and can associate the product pictures obtained by the photographing module and the detection results obtained by the processing module with the serial number information and / or model information and / or size information obtained by the barcode scanning module to unify the information of the same product, facilitating the traceability of product information and detection results throughout the quality inspection process.

[0068] Please refer to Figure 1 , Figure 3 and Figure 8 , in some embodiments, the barcode scanning module includes a first barcode scanning module 31 and a second barcode scanning module 32. Among them: The first barcode scanning module 31 is located above the barcode scanning input position 12, and the second barcode scanning module 32 is located below the barcode scanning input position 12. Either the first barcode scanning module 31 or the second barcode scanning module 32 can obtain the serial number information, and the other can obtain the model information and / or size information. Thus, when the target product is at the barcode scanning input position 12, the first barcode scanning module 31 and the second barcode scanning module 32 can simultaneously and synchronously input information for the target product.

[0069] In specific implementation, patterns to be scanned with product information can be set on the upper and lower surfaces of the target product, respectively. For example, the screen of the target product that is continuously conveyed on the conveying module faces upward, and when the target product is located at the scanning and entry position 12, its screen displays a QR code related to the model and size information of the target product itself, and a barcode bound to the target product is set on the bottom (i.e., the back of the product) by pasting or any other means. Taking the target product A as an example, when the target product A arrives at the code scanning and entry position 12, the first code scanning module 31 located above the code scanning and entry position 12 can obtain the model information, size information (length, width, thickness), etc. of the target product A by scanning the QR code located on the front of the target product A, and send it to the processing module; at the same time, when the target product A arrives at the code scanning and entry position 12, the second code scanning module 32 located below the code scanning and entry position 12 can obtain the number information of the target product A by scanning the bar code located at the bottom (i.e., the back) of the target product A, and send it to the processing module, so that the model information, size information and number information of the target product are associated with each other; when the processing module completes the detection of the target product A, it matches and saves its detection result with its number information. Therefore, the specific product information and detection result (including defect information) of the corresponding target product can be queried at any time through the number information.

[0070] For further information, see Figure 7 and Figure 8 In some embodiments, a second lifting platform can be set at the code scanning and entry position 12, so that after the target product is lifted from the bottom, it can be scanned and photographed to ensure that the bottom information of the product can be fully displayed, ensure the shooting effect, and improve the shooting efficiency.

[0071] See also Figure 11, in some embodiments, the photographing module 2 includes a first photographing device 21, a second photographing device 22, and a third photographing device 23. Among them: The first photographing device 21 is located directly above the detection position 14 and can photograph the target product located at the detection position 14 to obtain a first picture of the product from a top-down perspective; the second photographing device 22 is located obliquely in front of the detection position 14 and can photograph the target product located at the detection position 14 to obtain a second picture of the product from an obliquely forward perspective; the third photographing device 23 is located obliquely behind the detection position 14 and can photograph the target product located at the detection position 14 to obtain a third picture of the product from an obliquely rearward perspective. Thus, in any screen display state, the target product can be photographed from multiple angles simultaneously and synchronously by multiple photographing devices, with high working efficiency. For example, in specific implementation, the photographing direction of the second photographing device 22 can be exactly aligned with the center of the target product and form a 45° angle with the central axis in the front-rear direction of the target product; the photographing direction of the third photographing device 23 can be exactly aligned with the center of the target product and form a 45° angle with the central axis in the front-rear direction of the target product. When the screen of the target product displays any photographing state (such as a black screen, a white screen, or displaying a certain background picture), the first photographing device 21, the second photographing device 22, and the third photographing device 23 can photograph the target product simultaneously to obtain a front picture of the current screen and pictures at a 45° angle in the front-rear direction.

[0072] In some embodiments, two surface light sources are provided in the detection device, which can illuminate the target product when the target product is in the screen-off state for taking pictures for algorithm dust removal. Moreover, through the system server / software tool of the detection device, it is possible to control the target product screen to automatically switch to different color lit-screen pictures, and be able to automatically control the photographing device and / or the light source to adjust the lighting brightness according to the product model, and / or be able to automatically take and optimize pictures of screens with different light-emitting brightnesses.

[0073] Moreover, in some embodiments, an adjustment mechanism (such as a lifting mechanism and / or a horizontal adjustment mechanism) capable of adjusting the position of the photographing module is further provided in the detection device, and its driving device is communicatively connected to the processing module, so that the position of the photographing module can be specifically adjusted through the model information and / or size information of the target product, so as to ensure that no matter what model and size the target product is photographed, the target product can be located at the best photographing position of the photographing module.

[0074] In some embodiments, each work station in the conveying module respectively includes a conveying mechanism and a temporary storage mechanism. The temporary storage mechanism can rise through the conveying plane of the conveying mechanism to lift and temporarily store the target product from the conveying plane, and moreover, the temporary storage mechanism can lower through the conveying plane of the conveying mechanism to place the target product on the conveying plane.

[0075] For example, please refer to Figure 7 and Figure 8 , a first rolling member 111 and a first lifting table 112 are provided at the starting feeding position 11. The target product can be translated and conveyed by the first rolling member 111; when the first lifting table 112 is lifted by controlling the first driving device 1120, the target product can be lifted to be separated from the first rolling member 111, so as to temporarily store the target product at the starting feeding position 11; after controlling the first lifting table 112 to descend and placing the target product on the first rolling member 111, the target product can be continuously translated and conveyed by the first rolling member 111. A second rolling member 122 is provided at the code scanning and input position 12, as well as a first limiting member 121 in front of the code scanning and input position 12 and a second limiting member 123 behind the code scanning and input position 12. The target product can be translated and conveyed by the second rolling member 122. Controlling the first limiting member 121 to rise can limit and temporarily store the target product at the starting feeding position 11, and controlling the second limiting member 123 to rise can limit and temporarily store the target product at the code scanning and input position 12. In addition, the conveying mechanism at the detection position 14 can be the same as or similar to that at the code scanning and input position 12. A fifth rolling member 151 and a fifth lifting table 152 are provided at the end discharging position 15, and its specific structural arrangement can be the same as that of the starting feeding position 11, so this will not be elaborated herein.

[0076] Please refer to Figure 1 and Figure 3 , in some embodiments, a reversing position 13 is further included in the above-mentioned conveying module, which is located between the code scanning and input position 12 and the detection position 14. The reversing position 13 includes a code scanning and discharging position 1301 and a detection feeding position 1302, wherein: the starting feeding position 11, the code scanning and input position 12, and the code scanning and discharging position 1301 are arranged in sequence along the first conveying direction. The main function of the code scanning and discharging position 1301 includes discharging the target product after the code scanning is completed; the detection feeding position 1302, the detection position 14, and the end discharging position 15 are arranged in sequence along the second conveying direction. The main function of the detection feeding position 1302 includes temporarily storing the target product before the detection and feeding it into the detection position 14; the code scanning and discharging position 1301 and the detection feeding position 1302 are arranged side by side, and the conveying directions are opposite. Thus, reversing is achieved, making the equipment structure compact and the occupied space relatively small.

[0077] Specifically, please refer to Figure 13 and Figure 14, the commutation position 13 is provided with a first conveying mechanism 131, a second conveying mechanism 132 and a transmission mechanism 133. The transmission mechanism 133 is driven to lift by a lifting drive device 1331. Among them, the transmission mechanism 133 can be raised and lowered relative to the first conveying plane of the first conveying mechanism 131 in the code scanning discharging position 1301, and can be raised and lowered relative to the second conveying plane of the second conveying mechanism 132 in the detection feeding position 1302. When the transmission mechanism 133 is lowered, the first conveying mechanism 131 in the code scanning discharging position 1301 can receive the target product from the code scanning input position 12, and the second conveying mechanism 132 in the detection feeding position 1302 can transfer the target product to the detection position 14; when the transmission mechanism 133 is raised, the target product can be temporarily stored in the code scanning discharging position 1301 or the detection feeding position 1302, and the target product can be transferred from the code scanning discharging position 1301 to the detection feeding position 1302. Specifically in implementation, the transmission mechanism 133 can adopt a plurality of belt conveying mechanisms arranged in parallel and driven synchronously, but it is not limited thereto. In other embodiments, a roller / roller / ball, etc. with a height that can be adjusted up and down or other mechanisms capable of realizing driving and conveying can also be adopted.

[0078] In some embodiments, a positioning mechanism is provided at at least some workstations of the conveying module. Through the positioning mechanism, target products of different sizes can be adapted and centered. For example, the code scanning input position 12 is provided with a first positioning mechanism 17, which can position the target product at the first position, ensure the accurate position of the target product, and enable the smooth entry of the scanned information; for example, the detection position 14 is provided with a second positioning mechanism 16, which can position the target product at the second position to ensure that the target product is exactly at the best shooting position of each shooting device in the shooting module 2, ensure the shooting quality of the product picture, and thus ensure the accuracy of the detection result. Among them, please refer to Figure 9 and Figure 10 , the first positioning mechanism 17 includes a first clamping jaw 171 and a second clamping jaw 172 for clamping the target product to center it. Through these two clamping jaws, not only can the target product be centered, but also the target product can be lifted to a higher position, away from the second rolling member 122 of the code scanning input position 12, so as to lift the target product to the best scanning position. In addition, the second positioning mechanism 16 is a jacking positioning clamping jaw, which can center and lift the target product, so as to lift the target product to the best shooting position.

[0079] In a preferred embodiment, at least part of the positioning mechanism adopts a design with clamping torque feedback, which can adapt to target products of various different models and sizes, and solve the problem of difficulty in centering products of different sizes. Thus, during the operation of the detection device, it is possible to perform mixed-feed detection on target products of various different models and sizes. That is, the target products continuously coming in the incoming material logistics line connected to the feeding station of the detection device can be of various different models and sizes, and the positioning mechanism in the detection device can automatically make adaptive adjustments according to the different models received and perform detection on them.

[0080] In some embodiments, the conveying module part of the detection device is further provided with a blocking and positioning mechanism, which can block and position the target product at a specific position. First, it can achieve positioning and temporary storage. Second, it can avoid interference problems between adjacent products during the conveying process.

[0081] In some embodiments, the shooting module 2 can be adjusted in height according to the size of the target product. For example, according to the specific thickness of the target product, the horizontal height position where the shooting module 2 is located is adjusted to ensure that the target product to be photographed is exactly within the best shooting field of view of the shooting module 2, and it is beneficial to ensure that the target product can obtain high-quality pictures under the optimal light source environment. Among them, the specific thickness of the target product can be obtained by means of barcode scanning input, or a height detection device can also be set near the conveying module to specifically measure the thickness / height of the target product, so that the shooting module 2 can adjust its horizontal height position according to the measurement result. It can be seen that even if the detection device continuously receives target products of different models and different thicknesses, the shooting module 2 can automatically make adaptive adjustments, so that the models can be switched arbitrarily (i.e., mixed feed) to achieve the purpose of being compatible with multiple models.

[0082] In summary, when using the detection device provided by the embodiment of the present invention to perform screen defect detection on target products, the operator only needs to place the products on the external logistics line of the device to realize the automated detection process, achieving the purpose of replacing manual operation with automation, and the detection efficiency is very high. Moreover, when the operator places the products to be detected (i.e., the target products mentioned above), there is no strict position limit, and no professional operator is required. The products to be detected can automatically complete thickness detection inside the device, and the positioning mechanism can automatically assist the products to be centered automatically, so as to ensure that for each target product of different models and sizes, its perspective and style can be unified when taking pictures of the products.

[0083] In some embodiments, the detection device is further provided with a display module and a storage module. Among them:

[0084] The display module can display product images and / or test results; the storage module can match and store product images and corresponding test results with the target product number information. When the shooting module completes shooting of the target product and obtains the product image, it can automatically send the image information to the processing module, which automatically judges the color grade and other comprehensive solutions.

[0085] In addition, an embodiment of the utility model also provides a detection method, which can use the detection equipment mentioned above to detect screen defects of a target product. The detection method mainly includes the following steps: S1, moving the target product to the detection position 14 through the conveying module; S2, photographing the target product located at the detection position 14 through the shooting module 2 to obtain a product image; S3, analyzing the product image through the processing module to obtain the detection result of the target product.

[0086] Among them, in step S2, when the target product is located at the detection position 14, the processing module controls the target product to switch the screen state, and the shooting module 2 shoots the target product in different states respectively.

[0087] Furthermore, before step S1, step S01 is also included: the target product is transferred to the code scanning entry position 12 by the conveying module, and the target product is scanned by the code scanning module to obtain product information, and the product information includes model information and / or size information. At this time, in step S2, the shooting module 2 controls the target product to adjust to a preset screen brightness according to the model information; and / or the shooting module 2 adjusts the position of the shooting lens according to the size information.

[0088] In some embodiments, the processing module mentioned herein refers to a dedicated software tool installed on the detection device, so that the dedicated software tool cooperates with the automated mechanical equipment (including the conveying module, the shooting module, the code scanning module, etc.) to realize automatic input and automatic photo detection, and the position of the target product and the required bright screen background image can be automatically adjusted. In addition, the screen display brightness can be controlled online and the shooting parameters can be optimized online to achieve the best viewing angle and brightness of the photographed product.

[0089] In summary, please see Figure 1 , Figure 2 and Figure 16 The workflow of the detection device and detection method provided by the embodiment of the utility model may include:

[0090] Check the device startup, including powering on the device and turning on the computer;

[0091] Place the target products to be tested on the logistics line one by one;

[0092] When the logistics line supplies materials, the initial feeding position 11 in the conveying module of the detection device can receive the incoming materials and transfer them to the scanning and input position 12. The target product is blocked and positioned by the second limiting member 123, and is clamped and positioned by the first positioning mechanism 17, and the target product is lifted to the scanning position. When there is a target product at the scanning and input position 12, the initial feeding position 11 temporarily stores the new incoming materials until the scanning and input position 12 is empty, and then continues to transfer the target product to the scanning and input position 12.

[0093] When the target product is located at the scanning and input position 12 and is positioned and lifted by the first positioning mechanism 17, the first scanning module 31 above and the second scanning module 32 below the scanning and input position 12 simultaneously scan the front and back two-dimensional codes / barcodes (combined with bottom lighting) of the target product to input the product information into the processing module (i.e., the system server).

[0094] The target product that has completed scanning flows onto the first conveying mechanism 131 at the scanning and discharging position 1301 through the second rolling member 122. The transmission mechanism 133 rises to lift the target product and flows the target product from the scanning and discharging position 1301 into the detection feeding position 1302. The transmission mechanism 133 descends, and the target product is placed on the second conveying mechanism at the detection feeding position 1302, and the target product is further flowed to the detection position 14 through the second conveying mechanism 132, and the third limiting member 141 is raised by the blocking cylinder to block and position the target product.

[0095] The second positioning mechanism 16 positions and lifts the target product, thereby lifting the target product to the optimal shooting height. At this time, the processing module controls the target product to go black screen, bright screen (white screen), sends and switches the screen display negative film to the target product, and adjusts the screen display brightness / light source brightness according to its specific model information (because the actual screen display brightness of different target products is different) to obtain the optimal lighting brightness. And the processing module controls multiple shooting devices to simultaneously shoot the target product from multiple angles in different states.

[0096] The product pictures obtained by shooting are sent to the background processing module for analysis and recognition to detect screen display defects, and the product quality is judged based on this (that is, for detailed information such as defect type, position, length, width, area, quantity, etc., the product quality is judged according to the established standard). Among them, the detected defect information corresponds one by one to the number information of the target product, and is displayed and stored for query.

[0097] After the shooting is completed, the second positioning mechanism 16 places the target product on the rolling member at the detection position 14 and flows it to the end discharging position 15. After receiving the discharging signal, it flows to the logistics line.

[0098] This detection method can complete the evaluation of the screen grade of a product within 10 seconds. Normal manual judgment takes at least about 30 seconds. It can be seen that the detection equipment and method provided by the present utility model are more efficient than the traditional manual detection method. Therefore, the detection equipment and method provided by the present utility model can replace manual detection of the screen of the target product. Through an automated transportation module, a high-precision shooting module, and an intelligent processing module, it can obtain high-quality product pictures and standardized defect displays, and can improve the accuracy of the detection results of product screen display defects and the detection efficiency.

[0099] Finally, it should be noted that the detection equipment provided by the embodiments of the present utility model can not only be applied to the detection of screen defects of electronic products, but also be applied to other application scenarios, such as e-commerce platforms that require a large number of photos and online exhibits. Therefore, the present utility model does not make specific limitations on the specific applications of this detection equipment.
