[0002] When manufacturing products such as LCD modules, various tests are required before shipment to ensure the products are qualified. Typically, products are placed on the loading station of automated testing equipment for inspection, and the results are obtained. To avoid misjudgments, if a product's test result is defective, a re-inspection is necessary to confirm whether the product is indeed defective.

[0003] In related technologies, inspectors move products identified as defective to a re-inspection station for re-inspection, and then move the products to their corresponding locations based on the re-inspection results. However, this method involves a large amount of manual work and is inefficient in scenarios where the overall product yield is high. Summary of the Invention

[0063] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0064] In one embodiment, such as Figure 1 As shown, a product testing method is provided, the method being applied to the control module of a product testing equipment, the method comprising:

[0065] Step S110: Obtain the target working mode corresponding to the product testing equipment;

[0066] In some examples, product testing equipment is used to receive products that have undergone preliminary testing and to perform further processing. In other examples, after the products undergo preliminary testing and preliminary test results are obtained, further judgment is needed for products that are deemed defective in the preliminary test in order to ensure the accuracy of product testing and control product costs.

[0067] Figure 2 This is a schematic diagram illustrating the structure of a product testing device according to an exemplary embodiment, with reference to... Figure 2 As shown, the product testing equipment includes control modules, such as PLC (Programmable Logic Controller) control devices, re-judgment stations, human-machine interaction systems, transfer modules, transfer platforms, unloading modules, robots, etc.

[0068] For example, the control module is used to complete logic control and communicate with the host computer to achieve information exchange. Simultaneously, based on the detection results from the re-judgment station, it controls the transfer device to move products into / out of the loading station or transfer platform. The re-judgment station is used to complete specified tests on the products and provide feedback on the test data. The human-machine interface system includes a touchscreen (HMI) for setting equipment parameters, displaying relevant information, and manual operation. The transfer module is used for product handling. The transfer platform is used for product transfer. The unloading module mainly completes the exchange of relevant information based on the instructions from the control module. The robot is used for product handling.

[0069] For example, the target operating mode corresponding to the product testing equipment is obtained. In some examples, the product testing equipment may correspond to different operating modes. The target operating mode can be automatically generated by the control module, determined by parsing the obtained parameters, or obtained through other possible methods.

[0070] Optionally, the working mode may include, but is not limited to, discharge priority mode, re-judgment priority mode, and re-judgment mode, which can be determined according to the actual application scenario. In some possible implementations, the product testing equipment includes different types of workstations for placing products of different processes and categories.

[0071] Step S120: Determine the priority order of the loading station and the buffer station according to the target working mode, wherein the loading station is used to place the products to be tested after preliminary inspection, and the buffer station is used to place the products to be tested whose preliminary inspection results are defective.

[0072] For example, different work modes correspond to different workstation priority orders, where the workstation priority order determines the order in which products are picked up and placed on the workstations. Based on the target work mode, the priority order of the current loading workstation and the buffer workstation is determined.

[0073] Optionally, the loading station is used to place products to be tested after preliminary inspection. These products may include those that passed the preliminary inspection or those that failed. In some examples, upstream inspection equipment may place products that have completed preliminary inspection at the loading station for further processing by product inspection equipment; alternatively, the product inspection equipment may directly obtain products that have undergone preliminary inspection by upstream inspection equipment and place them at the loading station for further processing.

[0074] For example, the buffer station is used to place products that have been initially identified as defective, i.e., products that require re-evaluation. In some examples, the products in the buffer station can be transferred from the loading station, or they can be placed there by relevant personnel or equipment through the buffer station's delivery port. In some examples, when the number of products in the buffer station exceeds the preset buffer quantity, the control module can send an early warning signal to prompt relevant maintenance personnel to remove the products from the buffer device in a timely manner, ensuring the normal operation of the product testing equipment's workflow.

[0075] Step S130: According to the priority order, the target products to be tested that have been initially detected as defective in the loading station and / or the buffer station are sequentially moved to the re-judgment station; the re-judgment result corresponding to the re-judgment station is determined as the target detection result of the target product to be tested.

[0076] For example, after determining the priority order of the loading station and the re-judgment station, the target products to be tested that have been initially detected as defective in the loading station and / or the buffer station are sequentially moved to the re-judgment station for re-judgment. In some examples, after determining the priority order of the loading station and the buffer station, it is first determined whether there are target products to be tested with initially detected as defective in the stations with higher priority order. If there are, they are moved to the re-judgment station, and it is continued to determine whether there are target products to be tested with initially detected as defective in the stations with higher priority order; if not, it is determined whether there are target products to be tested with initially detected as defective in the stations with lower priority order. If there are, the target products to be tested are moved to the re-judgment station for re-judgment.

[0077] Optionally, the loading station, buffer station, and re-inspection station can each include one or more, and the specific number can be determined according to the actual application scenario. Before moving the product to the re-inspection station, it can be determined whether there is an empty station. If there is an empty station, the product can then be moved to the re-inspection station for review.

[0078] For example, after the target product to be tested is moved to the re-judgment station for re-judgment, the corresponding re-judgment result is obtained, which is the target inspection result of the target product to be tested. In some examples, the target product to be tested is further processed based on the target inspection result. In some possible implementations, if the target inspection result is a qualified product, the target product to be tested is moved to the qualified product unloading port for unloading; if the target inspection result is a defective product, the target product to be tested is moved to the defective product unloading port for unloading.

[0079] In some examples, the control module controls the transfer module, robot, etc. to move the product.

[0080] In this embodiment, during product testing, the target operating mode of the product testing equipment is obtained, and the priority order of the loading station and the buffer station is determined according to the target operating mode. Based on this priority order, target products that initially show as defective in the loading and buffer stations are sequentially moved to the re-judgment station. The re-judgment result corresponding to the re-judgment station is determined as the target testing result of the target product, thus achieving re-judgment of the target product. Different operating modes correspond to different station priority orders. While automating the re-judgment loading, different operating modes can be set based on actual application scenarios, corresponding to different loading sequences, improving the utilization rate of the re-judgment station. Furthermore, it balances the efficiency of normal material output from the loading station and the re-judgment of products with initial defective results, reducing manual workload and making it suitable for more application scenarios.

[0081] In one embodiment, the method further includes:

[0082] Obtain the number of products under test in the cache station;

[0083] If the number of products to be tested is greater than or equal to a preset number, the working mode of the cache station is switched to the unloading mode, and the cache station is controlled to execute the unloading process.

[0084] For example, the buffer station is used to store products to be tested that have been initially found to be defective. The control module monitors and judges the number of products in the buffer station. In some examples, if the number of products to be tested in the buffer station is greater than or equal to a preset number, it can be considered that there are too many products to be tested temporarily stored in the buffer station, and it is necessary to unload the materials to place subsequent products to be tested, so as to ensure the normal operation of the equipment.

[0085] In some possible implementations, when the working mode of the cache station switches to the unloading mode, the cache station can be controlled to automatically execute the unloading process, automatically placing the product to be tested into the preset unloading position through the unloading port. The cache station can also issue warning information to remind relevant personnel to execute the unloading process. Optionally, after the working mode of the cache station switches to the unloading mode, the cache station can also be directly used as a re-judgment station, where relevant re-judgment personnel can directly re-judge the products at the cache station and execute the unloading process based on the re-judgment results.

[0086] In this embodiment, the buffer station, in addition to serving as a material feeder and product buffer in different target working modes, also performs a material unloading process when there are a large number of products to be tested in the station. This effectively improves the utilization rate of the buffer station, takes into account both the normal material feeder process and the re-judgment process, avoids problems such as equipment downtime caused by too many products in the buffer station, and further improves the product testing efficiency.

[0087] In one embodiment, obtaining the target working mode corresponding to the product detection device includes:

[0088] Obtaining the preliminary detection results of historical products to be measured within a preset historical period;

[0089] Determining the target working mode according to the number of products with preliminary detection results being defective products and / or the number of products with preliminary detection results being qualified products.

[0090] Exemplarily, the target working mode of the product detection device can be determined according to the preliminary detection results within a preset historical period. In some examples, obtaining the preliminary detection results of historical products to be measured within a preset historical period, where the preset historical period can be determined according to the actual application scenario, and the historical products to be measured can include the products that have undergone preliminary detection within the preset historical period, and the historical products to be measured and the target products to be measured belong to the same product type.

[0091] Optionally, the preliminary detection results can include that the product is a defective product and the product is a qualified product. Determining the number of products with preliminary detection results being defective products and / or the number of products with preliminary detection results being qualified products among all historical products to be measured can determine the preliminary detection quality of the products within the preset historical period and determine the target working mode. In some examples, the more the proportion of defective products, the more products that need to be rejudged can be considered, and the priority of the rejudgment station can be increased. The more the proportion of qualified products, the more products that need to be normally unloaded can be considered, and the priority of the loading station can be increased.

[0092] In the embodiments of the present disclosure, the target working mode is determined according to the preliminary detection results of historical products to be measured within a preset historical period, so that the working mode can be automatically adjusted according to historical data during the product detection process, different working modes can be adapted to different scenarios, the utilization efficiency of various loading stations and the efficiency of product discharging and product rejudgment are effectively improved, the flexibility of product detection is enhanced, and it is applicable to more application scenarios.

[0093] In one embodiment, determining the target working mode according to the number of products with preliminary detection results being defective products and / or the number of products with preliminary detection results being qualified products includes:

[0094] Based on the total number of products of the historical products to be measured, determining the product qualification rate corresponding to the preset historical period according to the number of products with preliminary detection results being defective products and / or the number of products with preliminary detection results being qualified products;

[0095] If the product pass rate is greater than or equal to a preset threshold, the target working mode corresponding to the product testing equipment is determined to be the material loading priority mode; and / or, if the product pass rate is less than a preset threshold, the target working mode corresponding to the product testing equipment is determined to be the re-judgment priority mode.

[0096] For example, the product pass rate for a preset historical period can be determined based on the total number of products to be tested in the past and the preliminary test results. In some examples, the proportion of defective products can be determined by the ratio of the number of products with preliminary test results that are defective to the total number of products, and then the proportion of qualified products, i.e., the product pass rate, can be obtained; alternatively, the proportion of qualified products, i.e., the product pass rate, can be determined directly by the ratio of the number of products with preliminary test results that are qualified to the total number of products.

[0097] Optionally, when the product pass rate is high, a material loading priority mode can be used to improve the efficiency of secondary inspection material loading and unloading; when the product pass rate is low, a re-judgment priority mode can be used to improve the efficiency of re-judgment of defective products. The preset threshold can be set according to the actual application scenario. When the product pass rate is greater than or equal to the preset threshold, the product pass rate can be considered high, and the corresponding target working mode is set to the material loading priority mode; when the product pass rate is less than the preset threshold, the product pass rate can be considered low, and the corresponding target working mode is set to the re-judgment priority mode.

[0098] According to the embodiments of this disclosure, the product qualification rate corresponding to the preset historical period can be determined based on the preliminary test results within the preset historical period. When the product qualification rate is high, the working mode is determined to be the material feeding priority mode, and when the product qualification rate is low, the working mode is determined to be the re-judgment priority mode. This allows the corresponding working mode to be switched according to the product qualification rate in the actual application scenario, thereby improving the flexibility of product testing and re-judgment and ensuring the efficiency and accuracy of product testing.

[0099] In one embodiment, obtaining the target operating mode corresponding to the product testing equipment includes:

[0100] Obtain the target operating parameters sent by the host computer;

[0101] The target operating parameters are analyzed to determine the target operating mode corresponding to the product testing equipment.

[0102] For example, the target operating mode can be determined by parsing target operating parameters. In some examples, the product testing equipment communicates with a host computer, which can send target operating parameters to the control module. The control module then determines the target operating mode based on the received target operating parameters. In some examples, different operating parameters can correspond to different operating modes. The control module can determine the target operating mode based on the mapping relationship between operating parameters and operating modes, according to the target operating parameters.

[0103] Optionally, the target operating parameters can be determined directly by the host computer based on parameter input instructions; or they can be determined by the host computer based on historical detection information, such as historical operating modes and corresponding operating periods. The specific parameters can be determined according to the actual application scenario, and this disclosure does not impose any restrictions on this.

[0104] In this embodiment, the target working parameters sent by the host computer are parsed to determine the target working mode, thereby enabling the customization of the working mode of the product testing equipment, further improving the flexibility of product testing and making it suitable for more application scenarios.

[0105] In one embodiment, the target working mode includes at least one of a loading priority mode and a re-judgment priority mode, and determining the priority order of the loading station and the buffer station according to the target working mode includes:

[0106] When the target operating mode is the material loading priority mode, the priority of the material loading station is determined to be higher than the priority of the buffer station; and / or,

[0107] When the target working mode is the re-judgment priority mode, the priority of the buffer station is determined to be greater than the priority of the loading station.

[0108] For example, the target working mode includes at least one of a material loading priority mode and a re-judgment priority mode. When the target working mode is the material loading priority mode, the priority of the material loading station is determined to be greater than the priority of the cache station, that is, materials are preferentially taken from the material loading station and placed on the re-judgment station; when the working mode is the re-judgment priority mode, the priority of the cache station is determined to be greater than the priority of the re-judgment station, that is, materials are preferentially taken from the cache station and placed on the re-judgment station.

[0109] In this embodiment of the disclosure, the feeding station is prioritized in the feeding priority mode, and the buffer station is prioritized in the re-judgment priority mode. This can ensure the efficiency of product re-judgment and unloading at the feeding station in the feeding priority mode and the efficiency of product re-judgment at the re-judgment priority mode. It takes into account the utilization rate of different stations in different scenarios, improves the efficiency of product testing, and effectively saves labor costs.

[0110] In one embodiment, the step of sequentially transferring target products that have been preliminarily identified as defective from the loading station and / or the buffer station to the re-judgment station according to the priority order includes:

[0111] The target station is determined based on the priority order, the working status of the loading station, and the working status of the buffer station.

[0112] If there is an available workstation at the reassessment workstation, the target product that was initially found to be defective at the target workstation will be moved to the available workstation.

[0113] For example, the target station is determined based on priority order and the working status of the loading station and the buffer station. In some examples, a priority station is determined from the loading station and the buffer station according to priority order. Based on the working status of the priority station, it is determined whether there is a target product to be tested that has been initially detected as defective. If so, it is determined as the target station; otherwise, the next priority station is determined for judgment.

[0114] Optionally, after determining the target workstation, if there is an empty workstation in the re-judgment workstation, the target product to be tested that has been initially detected as defective in the target workstation is moved to an empty workstation in the re-judgment workstation for re-judgment.

[0115] In this embodiment, when there is an idle re-judgment station, the target product to be tested on the target station determined according to the priority is moved to the idle station. This enables the re-judgment of the product to be moved and re-judged according to the working status of the re-judgment station in the actual application scenario, realizes the automation of the re-judgment process, improves the utilization rate of the re-judgment station, further improves the efficiency of product testing, and is applicable to more application scenarios.

[0116] In one embodiment, after determining the target workstation, the method further includes:

[0117] If the target station is a loading station and there is no idle station among the re-judgment stations, the target product to be tested that has been initially detected as defective in the target station is moved to the buffer station.

[0118] For example, if the target station is a loading station, and there is no vacant station in the re-judgment station, the target product to be tested that has been initially detected as defective in the target station will be moved to the buffer station to free up the loading station for subsequent product placement.

[0119] In some possible implementations, if the target station is a cache station and there is no free station in the re-judgment station, we can continue to wait until there is a free station in the re-judgment station; or we can continue to judge the initial inspection results of the products on the loading station, and move the products with the initial inspection results of the loading station that are defective to the cache station until there is a free station in the re-judgment station, and then move the target product to be tested from the cache station to the re-judgment station for re-judgment.

[0120] In this embodiment, when there are no available stations in the re-judgment station, the target products that have been initially detected as defective in the loading station are moved to the buffer station. This avoids the problem of product output interruption or low efficiency at the loading station due to the loading station being occupied. Through the cooperation of various stations in the product testing equipment, the utilization rate of each loading station and the efficiency of product testing are effectively improved, and the workload of manual labor is reduced.

[0121] In one embodiment, taking the method described in this embodiment as applied to the control module of a product testing equipment as an example, the product testing equipment includes a re-judgment station, a transfer module, and a buffer station.

[0122] like Figure 3 As shown, taking the material-priority mode as an example, when the initial inspection result of the upstream inspection station is a defective product (i.e., NG), if there is a product being inspected at the re-judgment station, the control module will control the transfer module to place the product in the buffer station (i.e., NG Buff). If the re-judgment station is idle, the control module will control the transfer module to directly place the defective product in the re-judgment station. When the initial inspection result of the upstream inspection station is a qualified product, and the re-judgment station is idle, the control module will control the transfer module to take a product from the buffer station and place it in the re-judgment station for re-judgment based on the status of the upstream equipment. When the number of products in the buffer station exceeds the preset quantity, the unloading process can be executed to clear the buffer station.

[0123] In some examples, such as Figure 4 As shown, when upstream equipment malfunctions or the product pass rate is low, the product testing equipment directly performs reverse re-judgment logic, moving the materials in the buffer station to the re-judgment station for re-judgment. Optionally, if there is an idle station in the re-judgment station, the robot is controlled to retrieve the target product to be tested from the buffer station and move it to the re-judgment station to obtain the re-judgment result, and then the unloading process is executed based on the re-judgment result.

[0124] In some possible implementations, products can be proactively deployed for re-judgment. Products that were initially found to be defective outside the production line can be re-deployed from the cache station to the cache station for re-judgment.

[0125] For example, the control module can automatically switch the working mode according to the product qualification rate of the equipment, such as the feeding priority mode (corresponding to the priority forward feeding logic) and the re-judgment priority mode (corresponding to the priority reverse re-judgment logic), etc.

[0126] Optionally, the product testing equipment can be used as a standalone semi-automatic machine for re-judgment. Manual labor or AGV (Automated Guided Vehicle) can feed materials from the buffer station. After manual re-judgment, the materials can be unloaded through the discharge port, and the materials can be retrieved by manual labor or AGV from the discharge port.

[0127] Optionally, the product testing equipment can be integrated into an automated production line. A transfer platform receives materials from upstream equipment, and after verification, the products are discharged from both the unloading platform and downstream equipment. In this mode, it is compatible with personnel or AGVs loading and unloading from the buffer station. The control module can automatically switch the priority order of the products to be tested based on the status of the upstream and downstream equipment, significantly improving equipment utilization.

[0128] In some examples, when downstream equipment fails, the product inspection equipment can be used as a feeding machine. Qualified products can be placed directly at the feeding port and taken out manually or by AGV. Products with preliminary inspection results of being defective can be buffered at the buffer station if there is material available at the re-inspection station.

[0129] In one example, when there is insufficient manpower at the re-judgment station, a pass-through mode can be activated, where qualified products will go directly to downstream equipment, and products with preliminary inspection results indicating defects will be placed directly at the buffer station.

[0130] In one embodiment, taking the target working mode as the material loading priority mode as an example, after the product testing equipment receives the product from upstream, the control module will make a judgment based on the preliminary test results of the product. If the product is qualified, the control module will control the unloading and transfer module to pick up the material from the transfer platform and directly perform the unloading operation. If the preliminary test result of the product is defective, the control module will start the re-judgment process, control the transfer module to move the product to the re-judgment station for testing, and perform corresponding process scheduling based on the re-judgment results.
