Detailed Implementation

[0024] In this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, without necessarily requiring or implying any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. The present invention will now be further described in conjunction with the accompanying drawings and embodiments:

[0025] Please see Figure 1-3 A track-mounted aging chamber with CCD monitoring devices includes an aging chamber body and a control cabinet. The aging chamber body includes a preheating zone, a high-temperature aging zone, and a cooling zone. A feeding zone is located on the side of the aging chamber near the preheating zone, and a discharging zone is located on the side of the aging chamber near the cooling zone. A tunnel furnace is located within the aging chamber body, and the tunnel furnace is equipped with a conveying mechanism for transporting aging racks. CCD monitoring devices corresponding to the aging racks are installed on both sides of the tunnel furnace in the high-temperature aging zone. The conveying mechanism and the CCD monitoring devices are electrically connected to the control cabinet. The CCD monitoring devices are used to capture images of the products displayed on the aging racks.

[0026] By setting up a conveyor mechanism, the aging rack and the products (such as LCD screens) on the aging rack are transported to the high-temperature aging zone, allowing the products to operate under high temperature conditions and be monitored in real time by a CCD monitoring device. This facilitates the investigation of the products' operation under high temperature conditions. The CCD monitoring devices on both sides of the tunnel furnace in the high-temperature aging zone capture images of the products under high temperature loads, and by comparing them with standard images in real time, the quality of the products can be determined, thereby filtering out unqualified products (such as LCD screens displaying images with color differences, dark spots, dark lines, white spots, or white lines, which indicate unqualified products).

[0027] The tunnel furnace has air ducts on both sides, and a circulating fan is installed in the air duct. Ventilation holes and air vanes are provided on both the left and right sides of the tunnel furnace. The circulating fan is electrically connected to the control cabinet.

[0028] By adopting a left-right air outlet and return structure, with ventilation holes and air vanes on both sides, the temperature of aging products can be made uniform, greatly reducing overall energy consumption.

[0029] The control cabinet is installed on the outside of the aging chamber. Pneumatic doors are provided between the feeding area, preheating area, high-temperature aging area, cooling area, and unloading area. The pneumatic doors separate the feeding area, preheating area, high-temperature aging area, cooling area, and unloading area.

[0030] Furthermore, the CCD monitoring device includes a camera, a motion controller, an industrial computer, and a CPU image processor, wherein the camera is electrically connected to the industrial computer, the motion controller, and the CPU image processor, respectively.

[0031] The camera, which supports network transmission, is used to capture images displayed on the aging LCD screen during testing, according to the actual testing requirements.

[0032] The industrial control computer is the core of the entire system. It communicates with the camera via the local area network to transmit image data, analyzes the images, determines whether the display meets the expected results, and forms a traceable database. It also exchanges data with the MES via Ethernet.

[0033] The motion controller is mainly used to synchronize and coordinate the position of the camera, so that the image acquisition area can acquire images synchronously.

[0034] GPU (Graphics Processing Unit) is mainly used for image processing and computation, enabling the captured images to be effectively "displayed".

[0035] The CCD monitoring device is equipped with a camera, motion controller, industrial computer, and CPU image processor, which can better capture images displayed on the aging LCD screen.

[0036] The aging chamber contains two tunnel furnaces. Each tunnel furnace in the high-temperature aging zone has four aging rack stations. The aging racks have four layers, and each layer has two opposing LCD screen clamping fixtures. These fixtures are used to fix the LCD screens. Each clamping position of the LCD screen clamping fixture is assigned a serial number (SN) code. The position code is associated with the product's serial number (SN), thus linking the captured images with the product's SN code. Multiple cameras are installed in the tunnel furnaces of the high-temperature aging zone, with each camera corresponding to a station of the LCD screen clamping fixture on each aging rack. A total of 64 cameras are installed in the two tunnel furnaces. These 64 cameras can operate simultaneously or individually as needed. Each camera is equipped with a fan-cooled system to ensure normal operation in the high-temperature aging zone.

[0037] The industrial control computer is equipped with a system management module, an image acquisition module, a movement synchronization module, and an image processing module. The system management module is electrically connected to the image acquisition module, the movement synchronization module, and the image processing module.

[0038] The system management module is used to coordinate the image acquisition module, the movement synchronization module, and the image processing module.

[0039] The image acquisition module is used to acquire images displayed on the aging LCD screen.

[0040] The image processing module acquires images via TCP / IP protocol, compares and analyzes the acquired images with a standard library to determine if there are any quality issues with the LCD screen display, and stores and uploads the acquired images locally.

[0041] The movement synchronization module mainly coordinates the movement speed of the aging rack, the display screen of the LCD screen, and the synchronous operation of the camera when acquiring images.

[0042] The industrial computer is also equipped with an air-cooling control module, which is electrically connected to the system management module.

[0043] Movable mechanisms are installed on both sides of the tunnel furnace in the high-temperature aging zone. The CCD monitoring device is installed on the movable mechanism, and the movable mechanism is electrically connected to the control cabinet.

[0044] The moving mechanism can move the CCD monitoring device. Both the moving mechanism and the CCD monitoring device are electrically connected to the control cabinet, allowing them to be operated remotely via control signals. This enables the moving mechanism to automatically control the movement and stable positioning of the CCD monitoring device according to image acquisition requirements, ensuring that the CCD monitoring device performs image acquisition as needed.

[0045] The conveying mechanism, moving mechanism, and CCD monitoring device are electrically connected to the control cabinet to ensure that the display on the LCD screen on the aging rack, the moving speed of the aging rack, and the image acquisition by the camera are completely synchronized.

[0046] In the first embodiment, the moving mechanism includes a fixed plate and a drive cylinder, the drive cylinder is mounted on the fixed plate, and the CCD monitoring device is connected to the output end of the drive cylinder.

[0047] In the second embodiment, the moving mechanism includes a fixed plate and a moving plate. The fixed plate is equipped with a slide rail and a lead screw. The moving plate has a slider that is slidably connected to the slide rail. A nut is fitted onto the lead screw and connected to the moving plate. The fixed plate is equipped with a motor connected to one end of the lead screw. A moving frame is fixedly connected to the moving plate. The CCD monitoring device is mounted on the moving frame, and the motor is electrically connected to the control cabinet. Multiple CCD monitoring devices are mounted on the moving frame, with the number of devices corresponding to the number of layers in the aging rack. Each layer of the aging rack has corresponding CCD monitoring devices on both sides for product imaging. The monitoring time can be set as needed. The CCD monitoring devices can move left and right to image all products on the entire aging rack, thereby monitoring for any defective products and uploading the data to the control cabinet.

[0048] By electrically connecting the CCD monitoring device and the motor to the control cabinet, the moving mechanism and the CCD monitoring device can be operated via remote control signals. This allows the moving mechanism to automatically control the movement and stable positioning of the camera on the CCD monitoring device according to image acquisition requirements, ensuring that the camera acquires images as needed.

[0049] The material unloading area is equipped with a display, which is electrically connected to an industrial control computer. The display is used to show defective products.

[0050] The main functions of this utility model are:

[0051] This invention utilizes a conveyor mechanism to transport the aging rack and the products on it to a high-temperature aging zone. The products operate under high temperatures, and images are captured by a CCD monitoring device, enabling real-time monitoring and facilitating the investigation of product performance under high-temperature conditions. The left-right airflow structure, with ventilation holes and air vanes on both sides, ensures uniform temperature distribution in the aged products, significantly reducing overall energy consumption.
