Drive racks 310 are fixedly mounted on the outer wall of the cross blocks 34. The drive racks 310 are meshed with the corresponding drive gears 39. A servo motor 32 is mounted on the outer wall of the U-shaped frame 2 via a connecting seat 31. The power shaft of the servo motor 32 is fixedly connected to the drive shaft 38 through the connecting seat 31 via bearings. The testing mechanism includes a connecting rod 311 fixedly installed between the right cross blocks 34. Several area array cameras 314, which are mounted on the base for testing the polarizer of the display screen, are evenly installed on the outer wall of the connecting rod 311. The marking mechanism includes a mounting rod 35 fixedly installed between the left cross blocks 34, a marking seat 36 fixedly installed on the middle of the outer wall of the mounting rod 35, and a marking stamp 37 for marking the polarizer of the display screen with defects fixedly installed on the bottom wall of the marking seat 36. Two transmission racks 310 that mesh with the same transmission gear 39 are staggered vertically. Several mounting seats 312 are installed on both sides of the outer wall of the connecting rod 311. Positioning wheels 313 for conveying and guiding the polarizer of the display screen are rotatably installed on the inner wall of the mounting seats 312. In this embodiment of the utility model, the purpose of this setup is that the detection component 3, through the area scan camera 314, performs real-time detection of problems such as creases, pressure points, and imprints on the continuously passing display screen polarizer. When such problems occur, the external controller promptly sends a logic signal for a solution, controlling the marker base 36 and the marker stamp 37 to mark the display screen polarizer. After it is transported out, it can be quickly identified and removed by staff for further processing. The imprint of the marker stamp 37 can be washed away with water. The positioning wheel 313 is mainly used to construct a transport channel to prevent deviation, thereby achieving the effect of positioning detection.

[0024] Example 2: Please see Figures 1-6 This embodiment provides a technical solution based on embodiment one: the conveying mechanism 4 includes conveying rollers 41 rotatably installed on both sides of the inner wall of the conveying frame 1. The outer walls of the conveying rollers 41 are all connected by the same conveyor belt 42. The outer wall of the conveying frame 1 is fixedly installed with a drive motor 43. The power shaft of the drive motor 43 passes through the conveying frame 1 through a bearing and is fixedly connected to the roller shaft of the corresponding conveying roller 41. The supplementary lighting mechanism 5 includes a clamp 51 fixedly installed on the outer wall of the U-shaped frame 2. Several connecting arms 52 are evenly installed on the side wall of the clamp 51. The bottom end of several connecting arms 52 is fixedly installed with the same lamp holder 53. The bottom of the lamp holder 53 is equipped with a supplementary light 54 for enhancing the polarizer of the display screen and improving the detection effect. In this embodiment of the utility model, the purpose of this arrangement is that the conveying mechanism 4 is mainly used to convey the polarizer of the display screen, while the conveying speed is controllable. The supplementary lighting mechanism 5 can supplement and enhance the polarizer of the conveyed display screen, and assist the area scan camera 314 in quickly identifying defects in the display screen.

[0025] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0026] The working principle of this device is as follows: During operation, the servo motor 32, area scan camera 314, drive motor 43, and supplementary lighting mechanism 5 are electrically connected through an external power supply and controller. The drive motor 43 drives the conveyor roller 41 to rotate, which in turn drives the conveyor belt 42 to start conveying the polarizer of the display screen. The polarizer of the display screen is conveyed from the left to the right. The supplementary lighting lamp 54 installed at the bottom of the connecting arm 52 and the lamp holder 53 is turned on to provide supplementary lighting to the surface of the polarizer of the display screen passing through the bottom. During the process of the conveyor belt 42 conveying the polarizer of the display screen, the positioning wheel 313 installed at the bottom of the mounting base 312 rolls along the outer wall of the conveyor belt 42. The positioning wheel 313 limits the edge position of the polarizer of the display screen to prevent deviation and tilting, so that the polarizer of the display screen is conveyed along the preset path between the positioning wheels 313, thereby achieving the effect of accurate positioning. The area scan camera 314 performs surface inspection on the progressively conveying display polarizer to detect creases, pressure points, and imprints. When the area scan camera 314 detects a defect in the display polarizer, it transmits the detection result to the external controller in real time and simultaneously sends a processing logic signal to start the servo motor 32 on the connecting base 31 to control the rotation of the transmission shaft 38 and the transmission gear 39. The transmission gear 39 drives the meshing transmission rack 310 to engage in transmission. The transmission rack 310 drives the cross block 34 to slide in the inner wall of the corresponding cross groove 33, causing the transmission rack 310 on the right to drive the connecting rod 311, the mounting base 312, and the area scan camera 314 to rise. The transmission rack 310 on the left drives the mounting rod 35, the marking base 36, and the marking stamp 37 to fall. The falling of the marking stamp 37 marks the outer wall of the display polarizer. When the conveyor belt 42 transports the display screen polarizer outward, it facilitates the quick identification of defective display screen polarizers by the staff. If the area scan camera 314 continuously detects no abnormalities in the display screen polarizer, the connecting seat 31 remains in standby mode, and the area scan camera 314 continues to inspect the display screen polarizer. After the marking stamp 37 marks the defective display screen polarizer, the servo motor 32 controls the marking stamp 37 and the area scan camera 314 to return to their original positions through the detection component 3 to continue the inspection work.
