Description

Technical Field

[0001] This invention relates to the field of EPD product inspection technology, specifically to a method and apparatus for quickly changing the inspection procedure for electronic paper EPD products. Background Technology

[0002] In the manufacturing process of electronic paper EPD products, product inspection is a key link to ensure product quality. Due to its strong targeting and convenient operation, the test fixture is still the core structure widely used in the inspection process of electronic paper EPD products. It adopts an integrated structural design, and the inspection procedure is fixedly bound to the test unit of the fixture.

[0003] It needs to be explained that when different models and specifications of electronic paper EPD products need to be inspected, the test unit of the test fixture must be reprogrammed and replaced. Since program programming takes a certain amount of time, inspection personnel have to wait in line, which greatly extends the inspection preparation time, seriously affects the overall production inspection efficiency, and makes it difficult to meet the high-efficiency inspection requirements of mass production.

[0004] Secondly, in the integrated design of the test fixture, the test unit and the main body of the fixture cannot be separated. If the test unit fails or is damaged, the entire test fixture must be shut down for disassembly and repair. During the repair period, no product inspection work can be carried out, resulting in low utilization of the test fixture and indirectly increasing production and manufacturing costs. Furthermore, the program change operation of traditional test fixtures is complicated and requires high professional skills from the inspection personnel. Frequent program burning operations may also reduce the service life of the test unit, further affecting the stability and continuity of the inspection work. In view of the above problems, this invention proposes a solution. Summary of the Invention

[0005] The purpose of this invention is to provide a method and apparatus for rapid switching of inspection procedures for electronic paper (EPD) products, thereby achieving rapid switching of inspection procedures, reducing inspection preparation time, improving the utilization rate of test fixtures, and reducing production inspection costs.

[0006] The objective of this invention can be achieved through the following technical solution: a method for quickly changing the inspection program of electronic paper (EPD) products, employing a detachable independent test unit group scheme. An inspection framework is constructed by combining several independent test unit groups. Each independent test unit group can pre-prepare the corresponding inspection program. The specific operation steps are as follows: Step 1: For the type of electronic paper EPD product to be inspected, download the matching exclusive inspection program for the independent test unit group; Step 2: Assemble the independent test unit group that has completed the program download into the corresponding installation position of the inspection fixture to complete the quick docking of the module and the fixture; Step 3: Connect the power supply and auxiliary testing equipment to the inspection fixture to complete the equipment debugging before inspection; Step 4: Start the inspection process and perform inspection operations on the electronic paper EPD product using the assembled test unit group.

[0007] Further configuration: In step one, multiple independent test unit groups can pre-program the inspection programs corresponding to different types of electronic paper EPD products to form a program pre-store module group.

[0008] Further configuration: In step two, the assembly method of the independent test unit group and the inspection fixture is tool-free and easy to disassemble and assemble.

[0009] Further configuration: If a certain independent test unit group malfunctions or the program needs to be updated, the module can be disassembled for repair or the program can be re-burned, while the remaining test unit groups can continue to work with the inspection fixture to complete the inspection work.

[0010] The present invention also proposes a quick-change device for the inspection program of electronic paper EPD products, including an inspection fixture body and multiple independently detachable test unit groups. The inspection fixture body is provided with a signal docking structure, a power supply structure and an inspection control structure that cooperate with the test unit groups. The test unit groups are provided with a program storage structure, a product connection structure and an auxiliary detection docking structure. The test unit groups are detachably connected to the inspection fixture body and form a signal transmission process through the signal docking structure, and the power supply structure provides working power to the test unit groups.

[0011] The test unit group's program storage structure supports repeated erasure and rewriting, and the stored test program can be updated according to the test requirements.

[0012] The following configuration is further provided: the connection between the test unit group and the main body of the inspection fixture is provided with a foolproof positioning structure.

[0013] The present invention has the following beneficial effects: This invention improves upon the traditional integrated structure of testing fixtures by proposing a design that integrates detachable independent testing units with the main body of the testing fixture. This binds the testing program to an independent module, enabling program switching through pre-programming and rapid module replacement. This addresses technical issues such as long program replacement waiting times and low fixture utilization in existing technologies. Furthermore, it incorporates a foolproof positioning structure and a rewritable program storage structure to optimize the device's practicality and stability.

[0014] The operation process of this invention is described as follows: The method steps of this invention are simple and clear, with low operational difficulty. Inspection personnel can quickly master it without professional skills. Utilizing the tool-free and convenient disassembly and assembly of the test unit group, the time for changing inspection procedures can be significantly shortened, avoiding personnel queuing and improving production inspection efficiency. A single test unit group can be independently repaired, replaced, and updated without affecting the normal use of other modules, ensuring the continuity of inspection work and improving the utilization rate of the test fixture. Multiple test unit groups can pre-store different programs to adapt to the inspection needs of multiple product models, with strong versatility, effectively reducing production inspection costs. The connection between the test unit group and the main body of the inspection fixture is equipped with a foolproof positioning structure to ensure correct assembly direction and stable connection, avoiding inspection errors caused by connection problems. The program storage structure supports repeated erasing and writing, and the inspection program can be adjusted in a timely manner according to product upgrades or inspection standard updates, extending the service life of the device and improving the stability of device operation and the accuracy of inspection results.

[0018] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. 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.

[0019] Example 1: Taking an integrated testing fixture for electronic paper (EPD) as an example, during actual operation, the difference in its working time leads to a significant increase in inspection preparation time, seriously affecting the overall production and inspection efficiency, and also requiring a high level of skill from the operators. This invention proposes a solution to this problem: Reference Figures 1-4 This embodiment of a method for quickly changing the inspection program of electronic paper EPD products adopts a detachable independent test unit group scheme. The inspection framework is built by combining several independent test unit groups. Each independent test unit group can be pre-prepared to complete the corresponding inspection program burning, without waiting for the program to be burned at the inspection site. The specific process is as follows: 1. Program pre-programming: For each type of electronic paper EPD product to be inspected, a dedicated testing program is downloaded to each independent test unit group using a dedicated programming device to ensure that the program is accurately matched with the product testing requirements; 2. Module Assembly: Assemble the independent test unit groups that have completed program download to the designated installation positions of the inspection fixture according to their corresponding installation positions, so as to realize the rapid docking of the test unit groups and the inspection fixture, and ensure signal transmission and power supply. 3. Equipment debugging: Connect the external power supply to the inspection fixture, and connect the auxiliary testing equipment (such as power meter) to the test unit group to complete the power debugging, signal calibration and other preparatory work before inspection; 4. Product Inspection: Initiate the inspection process and use the assembled test unit group to inspect various performance indicators of the electronic paper EPD product to be inspected. During the inspection process, the inspection status can be monitored in real time through the control structure of the inspection fixture.

[0020] In step one, according to the various types of electronic paper EPD products to be inspected in the production plan, the corresponding inspection programs can be pre-programmed for multiple independent test unit groups to form a program pre-store module group. When it is necessary to switch the inspection product type during the production process, there is no need to burn the program on site. The corresponding pre-stored program test unit group can be directly selected, which greatly shortens the changeover time and adapts to the rapid inspection needs of multiple product models. In step two, the assembly method of the independent test unit group and the inspection fixture is to facilitate easy disassembly and assembly without tools. The connection structure of the test unit group and the fixture is designed to be simple. The inspectors do not need to use additional disassembly tools. They can quickly complete the installation and replacement of the module by manual operation, which reduces the difficulty of operation and improves the replacement efficiency. In practice, if a single test unit group malfunctions (such as abnormal signal transmission, program errors, etc.) or the program needs to be updated, the faulty module can be disassembled for repair or the program can be re-burned. The remaining normal test unit groups can continue to work with the inspection fixture to complete the inspection work without stopping the machine to wait for repairs, thus ensuring the continuity of the inspection work. The above content represents the basic technical aspects of this invention.

[0021] Example 2: Based on Example 1, its structural components are described as follows: A quick-change device for the inspection procedure of electronic paper (EPD) products includes an inspection fixture body 1 and several independently detachable test unit groups 2. The inspection fixture body 1 integrates a signal docking structure 3, a power supply structure 4, and an inspection control structure 5. The signal docking structure 3 adopts a pluggable interface design for easy and quick docking with the test unit groups 2. The power supply structure 4 is equipped with a power interface for connecting to an external power source and distributes a stable voltage to the test unit groups 2 through an internal circuit. The inspection control structure 5 is equipped with operation buttons and a display panel, which can realize the control of the inspection process and the real-time display of inspection data.

[0022] Test unit group 2 is equipped with a program storage structure 6, a product connection structure 7, an auxiliary testing docking structure 8, and a foolproof positioning structure 9. The program storage structure 6 uses a rewritable memory chip, which can be used to write or update the inspection program through a dedicated programming device. The product connection structure 7 adopts a snap-fit ​​design, which can quickly fix the electronic paper EPD product to be inspected and ensure a firm connection. The auxiliary testing docking structure 8 is a standard interface that can be adapted to common auxiliary testing equipment. The foolproof positioning structure 9 is a raised positioning block that matches the positioning groove on the main body 1 of the inspection fixture, ensuring that test unit group 2 can only be assembled in the correct direction. The specific operating procedure for rapid replacement of electronic paper EPD products using the above-mentioned device during actual testing is as follows: Pre-preparation stage: Based on the electronic paper EPD product models to be inspected in the production plan, prepare several independent test unit groups 2. Download the matching exclusive inspection program to the program storage structure 6 of each test unit group 2 using a dedicated programming device to form a program pre-store module group. Module assembly: When a certain model of electronic paper EPD product needs to be inspected, the inspector holds the test unit group 2 with the corresponding program already burned in, aligns it with the signal docking structure 3 on the main body of the inspection fixture through the foolproof positioning structure 9, and manually inserts it to complete the assembly. No additional tools are required, and the assembly process only takes a few seconds. Equipment debugging: Connect the external power supply to the power supply structure 4 of the main body of the inspection fixture 1 to power the device. At the same time, connect the auxiliary testing equipment to the auxiliary testing docking structure 8 of the test unit group 2. Start the power debugging through the operation button of the inspection control structure 5 to ensure stable power supply and normal signal. Product Inspection: The electronic paper EPD product to be inspected is fixed on the test unit group 2 through the product connection structure 7. The start button of the inspection control structure 5 is operated to start the inspection process. During the inspection, the inspection data is displayed on the display panel in real time. After the inspection is completed, the inspected product can be removed directly and the next product to be inspected can be replaced to continue the inspection. Program Replacement / Module Maintenance: When different models of electronic paper EPD products need to be inspected, simply unplug the current test unit group 2 and replace it with another test unit group 2 that has the corresponding program pre-stored. Repeat steps 3-4 to quickly start the inspection of the new model product. If a test unit group 2 malfunctions, directly disassemble and repair or replace it. If the inspection program needs to be updated, remove test unit group 2 and update the program using a dedicated programming device. After the update is completed, it can be used again.

[0023] Based on the above, the core of this invention lies in the coordinated operation of program pre-programming and rapid module replacement. In the pre-preparation stage, the program storage structure is pre-written with the inspection program for the corresponding product model using a dedicated programming device. Multiple test unit groups can store different programs to form pre-stored module groups, completely eliminating the limitations of traditional fixtures that require "on-site programming and waiting." When it is necessary to switch inspection products, the inspection personnel do not need to perform complex program update steps. They only need to quickly connect the test unit group carrying the target program to the signal docking structure of the inspection fixture body through tool-less disassembly and assembly. The power supply structure automatically and synchronously distributes a stable voltage to the test unit group. The entire product changeover process can be completed in just a few seconds, effectively solving the efficiency bottleneck problem of multi-model product inspection in mass production and meeting the inspection needs of high-efficiency production. Furthermore, the detachable design of the independent test unit group and the main body of the inspection fixture ensures that the maintenance and operation of each component do not interfere with each other. During operation, if a test unit group experiences faults such as abnormal signal transmission or program errors, or if the program needs to be updated due to product upgrades, the module can be directly disassembled. At this time, the power supply structure and inspection control structure of the main body of the inspection fixture will continue to operate normally, and the remaining test unit groups can continue to cooperate with the main body of the fixture through the signal docking structure to complete the inspection work without the need for overall shutdown. Compared with the traditional integrated fixture structure design, this solution significantly reduces equipment idle losses. At the same time, the independent maintenance and reprogramming of individual modules also reduces the overall equipment maintenance cost, indirectly reducing the production and manufacturing cost. From the perspective of operational technical requirements, the connection between the test unit group and the main body of the fixture is equipped with a foolproof positioning structure. During assembly, the positioning block and the positioning groove on the fixture are precisely matched, ensuring the correct assembly direction without the need for professional skills. This avoids rework due to connection errors. The tool-free disassembly and assembly structure simplifies the module installation and disassembly process. Inspectors do not need to master complex equipment operation skills and can complete module replacement by manual operation. During operation, key parameters such as power supply stability and signal transmission status can be monitored in real time, facilitating quick troubleshooting of simple problems. This further reduces the operation threshold and error rate, ensuring the continuous operation of the inspection process. The program storage structure supports repeated erasure and rewriting. During operation, the test unit group can be disassembled and the program re-burned at any time according to the needs of product iteration and inspection standard updates, without the need to replace the entire module or fixture. This allows the device to adapt to inspection needs at different stages for a long time. Multiple independent test unit groups can pre-store inspection programs for different models and specifications of electronic paper EPD products, forming a universal program pre-store module group. One set of fixture main body, together with different test unit groups, can meet the inspection needs of multiple models of products. There is no need to configure special fixtures for different products, which greatly reduces the cost of fixture procurement, while also reducing the space occupied by equipment storage and improving the utilization rate of production site. Finally, it should be noted that during assembly, the foolproof positioning structure ensures precise docking between the test unit group and the fixture body, avoiding signal transmission abnormalities caused by loose connections or incorrect orientation, thus reducing inspection errors. During the inspection process, the signal docking structure adopts a plug-in design, achieving stable signal transmission between the module and the fixture. The power supply structure provides a continuous and stable voltage to the test unit group through built-in circuitry, avoiding data distortion caused by power supply fluctuations. The inspection control structure monitors the entire operation process in real time and can promptly report abnormal equipment statuses, facilitating quick handling by operators. This pre-programmed mode reduces the wear and tear on the test units caused by frequent on-site programming in traditional solutions, extends the service life of core components such as the program storage structure, and further improves the stability of device operation and the accuracy of inspection results.
