[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention adopts a conveyor belt to transport the display screen, and gradually detects and repairs the scratch defects on its surface during the transportation process. A scanning and cleaning mechanism is used to scan and record the display screen and perform preliminary cleaning to improve the accuracy of scratch detection; a CCD detection mechanism is used to make the detection of scratches on the surface of the display screen more accurate and reliable, which is helpful to timely discover and locate existing problems; a rough grinding mechanism is used to effectively remove deep scratches on the surface of the display screen through grinding, dust collection, application of repair liquid and UV lamp curing, thereby improving the repair effect; a fine grinding mechanism is used to grind the repair part with a more refined grinding sheet and use a polishing machine and polishing agent, thereby further improving the repair accuracy of the display screen surface and ensuring that the display effect after repair reaches the best state; a cleaning mechanism is used to help ensure the cleanliness of the display screen after grinding and polishing; the use of this repair system integrating detection and grinding and repair can not only realize the repair of scratches of different degrees, but also improve the applicable scope of the equipment repair and improve the quality of the repair.

[0017] 2. The present invention adopts a conveyor belt to transport the display screen, and uses a support plate and an electromagnetic suction cup to support and fix the display screen during processing to ensure stability and safety during the processing; the multi-axis mobile machine is a multi-level, multi-axial precision moving system, through which high-precision movement can be performed in the horizontal and vertical directions to ensure accurate repair of scratches on the display screen. The structures of various components are coordinated with each other to form an efficient and stable multi-axis grinding mechanism.

[0018] 3. The coordinated use of the syringe and the metering pump, under the measurement and control of the control panel, can inject corresponding amounts of repair liquid for scratches of different sizes, thereby reducing the subsequent polishing time and polishing intensity, saving the repair liquid while improving the polishing efficiency, thereby achieving precise injection and control of the repair liquid, and ensuring the stability and controllability of the repair process.

[0019] 4. The injection nozzle of the first syringe is set in the through hole of the first slag suction device, and a protective cover is set under the second syringe, both of which are to protect the injection nozzle and prevent external dust or debris from contaminating the injection nozzle, thereby contaminating the repair fluid and polishing agent and reducing the repair effect.

[0020] 5. The CCD camera is a device used to capture images of the display screen surface. Signal processing is performed through a digital signal processor, which is responsible for receiving, processing and analyzing image information from the CCD camera. This intelligent design enables the CCD detection mechanism to accurately identify the location and extent of scratches on the LED display screen in real time.

[0021] 6. An atomizing nozzle is installed at the bottom of the liquid buffer box to spray the liquid on the display screen in the form of mist. This method allows the cleaning liquid to cover the entire screen surface more evenly, improves the cleaning effect, and avoids using too much cleaning liquid, which may cause it to penetrate into the interior of the display screen and cause damage to the display. A frame-shaped cleaning cloth is fixedly installed on the bottom surface of the fourth mounting block surrounding the atomizing nozzle, and the cleaning cloth is higher than the atomizing nozzle. This design is used to effectively absorb and clean the liquid sprayed by the atomizing nozzle, thereby improving the cleaning effect.

[0022] 7. The calibration scanner and the information calibration points work together to achieve precise work between various components. By cooperating with the information calibration points, the system can ensure that operations at each stage are carried out in accordance with predetermined accurate standards, thereby improving the accuracy of repairs.
