Description

Technical Field

[0001] This invention relates to the field of engineering equipment and industrial retrieval technology, specifically to an LCM fully automatic multi-functional testing and classification device. Background Technology

[0002] With the continuous development of technology and the increasing popularity of mobile phones, smart wearables, tablets, laptops, and other electronic devices, the demand for LCMs (Liquid Display Modules) is constantly growing, and diversified products have emerged in the market. Factories need an automated retrieval and classification device to improve production efficiency, reduce employee error rates, and simultaneously assess screen display quality and classify LCMs. However, many manufacturers lack a multi-functional LCM performance retrieval device. Most still rely on a combination of human and machine methods to test LCM performance, achieving only partial function testing and using sampling methods, unable to perform performance testing on every single product. In recent years, the rapid development of automation technology has driven the intelligentization and efficiency of fully automated retrieval devices, greatly improving production efficiency and product qualification rates.

[0003] Limitations of Traditional Testing Methods: Conventional LCM retrieval devices are relatively simple, with each performance test requiring a separate device and typically relying on manual labor and semi-automatic equipment. Therefore, traditional methods have the following limitations: High labor costs: Manual retrieval and judgment require significant manpower, are labor-intensive, and prone to human error; Low efficiency: Manual testing is slow and cannot meet the needs of large-scale production; Limited LCM performance retrieval devices: Relying on manual labor and semi-automatic equipment leads to significant data errors; Insufficient data accuracy: Due to limitations in experience, the stability and consistency of test results are difficult to guarantee, leading to errors. Furthermore, the differences between each display component make manual classification difficult in mass production; Lack of data and judgment traceability: Traditional manual testing requires visual reading and immediate determination of product specifications, necessitating manual data recording, which is voluminous and difficult to implement. Therefore, data and judgment results are difficult to preserve and trace. Given the different customer groups, an automated multi-functional retrieval and classification device can categorize LCMs into different product levels for customers to choose from, offering better value for money, more customer choices, and easier cooperation.

[0004] In conclusion, the display module industry urgently needs more efficient and better technologies to address these challenges and increase market share. Summary of the Invention

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1:

[0023] Please see Figure 1 - Figure 3As shown in the figure, an embodiment of the present invention provides a fully automatic multi-functional testing and classification device for LCMs, comprising two parts: automatic LCM retrieval and matching, and functional testing and classification. The automatic LCM retrieval and matching, and functional testing and classification device mainly consists of multiple modules, including a host computer, a control module, a storage module, a laser scanning module, a high-precision camera module, and a communication control module. This multi-functional testing and classification device aims to simplify the process of LCM lighting testing and product classification. Any trained operator can easily master the process to classify LCM products. Simultaneously, the system can transmit the product serial number corresponding to the classified data on the display screen to the MES system in real time. This design not only reduces the complexity of equipment use but also significantly improves work efficiency. Furthermore, the present invention can be applied to lighting testing and product classification of LCMs of different specifications. Only simple adjustments and initialization operations are needed to achieve fast and real-time lighting testing and product classification of LCMs, greatly improving the efficiency of actual production.

[0024] The host computer mainly consists of an MES system and a cloud disk; it primarily stores commercially available LCM driver code and the company's mass-produced product driver code, which can be stored long-term. The retrieval and matching module can retrieve the relevant driver code by reading the IC ID number and adding the product information scanned by the operator. The MES system mainly handles the traceability of individual products and saves product data statistics. The control module is the core architecture of this device, mainly responsible for data calculation, management and coordination of system resources, and the normal operation of hardware and software. It is the key guarantee for the reliability, real-time performance, security, and high efficiency of this invention. The storage module is mainly responsible for data reading, writing, management, and protection. In this case, it is mainly used for caching data for functions such as mura / brightness / uniformity / brightness / foreign object calculations by the camera module and laser module.

[0025] The laser scanning module is primarily responsible for rapidly scanning for functional defects in the LCM, such as mura, bright spots, and foreign objects. The high-precision camera module is used to acquire uniformity and brightness data of the LCM, accurately collecting and transmitting relevant data for calculation. Combined with the camera module, the laser scanning module can automatically classify products based on their needs and differences. The communication control module is mainly responsible for the acquisition and transmission of data from the high-precision camera and laser scanning module, the transmission of classified data, and coordinating communication between multiple modules. To address the limitations of traditional single-to-one programming devices, this invention employs an automatic retrieval and matching module to implement protocols from multiple driver ICs on the market, retrieving corresponding initialization codes to enable one device to correspond to different display configurations. The judgment system can be connected to any database or data traceability system, facilitating judgment results and data traceability, and contributing to overall product quality control.

[0026] In terms of specific operation and function, after the operator starts the device, the system will read back the IC ID, match and judge to find the corresponding driver IC initial programming program, and through the back transmission parameters collected by the camera, the high-precision camera module calibrates the initial parameter values, and finally programs the optimized LCM driver code and uploads it to the MES system.

[0027] The overall process of the determination method of the present invention is as follows: Figure 2 As shown, it includes the following steps:

[0028] Device connection

[0029] Before performing the product programming test, it is necessary to fully consider the differences in product size and interface, as this process involves whether the screen can be successfully lit.

[0030] (1) The corresponding dot screen adapter cable needs to be found;

[0031] (2) Connect the cloud drive and check if the communication is normal;

[0032] System Initialization

[0033] After completing the device adjustments and connections, the entire control system needs to be initialized. The initialization process is as follows: Figure 3 As shown. Before initialization, the device, LCM, and host computer need to be connected, and then the database needs to be imported. Next, the entire system initialization can begin, following these steps:

[0034] The first step is that during system startup, the system attempts to read the configuration file along with relevant information obtained by the operator through scanning to obtain information related to the LCM driver code. If the reading fails, manual input or mode selection is required.

[0035] The second step requires the tester to enter their workstation number and personnel number to enter the operating mode. Afterwards, the product's serial number (SN) and QR code can be entered into the host computer's software interface. The system then reads the IC's ID number and sends a command to the host computer to confirm the line connection status.

[0036] Third, if the host computer receives data returned by the IC, the initialization is successful. Otherwise, the initialization fails.

[0037] If initialization fails, check the connection lines and repeat the above steps to perform initialization.

[0038] Product loading and QR code scanning.

[0039] After system initialization is complete, material loading can begin. During loading, special care must be taken to ensure the product is placed securely and the communication adapter cable is properly connected to guarantee normal communication between the screen and the testing device. Simultaneously, to protect the product from damage, operators should carefully inspect it to ensure no physical damage is caused.

[0040] Next, operators need to use a barcode scanner to scan the QR code on the product. The QR code stores important information related to the product, such as the product model, batch number, and other parameters. This operation not only facilitates subsequent data storage but also enables effective traceability management, allowing each measurement process to be recorded and tracked.

[0041] Starting device

[0042] After completing product loading and QR code scanning, the operator needs to press two start buttons simultaneously to activate the testing device. The LCM then lights up; one button confirms the driver code information, and the other starts the device.

[0043] The test data is then transmitted to the host computer.

[0044] The completed product results and their SN codes are imported into the Mes system in real time. Results for A / B / C category products are accurately recorded and associated with their corresponding SN codes. Each product's SN code serves as a unique identifier in the production process, effectively tracking its production and testing history.

[0045] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
