The image detection mechanism can perform fast and efficient multi-angle detection on the curved screen assembly 12.

[0047] The working principle of the present invention is: when in use, first, place the curved screen assembly 12 to be tested on the fixture, specifically, clamp the back of the curved screen assembly 12 on the clamping plate 7, and then tighten the fastening bolt 10 to drive the fastening block 9 to move outward along the fastening groove 8 until the fastening block 9 is against the inner wall of the curved screen assembly 12 to complete the fastening. Next, the conveying plate 5 together with the curved screen assembly 12 is placed on the right end of the conveyor belt 4, and then the calibration is completed through the calibration mechanism. Specifically, the second cylinder 17 operates to retract the output shaft to drive the push plate 18 to move, and the push plate 18 drives the first calibration arm 19 to retract into the first transverse groove 21. During the process, through the engagement of the first tooth 25 with the first gear 24, the second calibration arm 20 is synchronously retracted into the second transverse groove 22. Finally, the ends of the first calibration arm 19 and the second calibration arm 20 are brought close to each other until they are against the corresponding fastening bolts 10. If the contraction length of the output shaft of the second cylinder 17 is not the preset length when the calibration arm is against the fastening bolts 10, it means that the curved screen assembly 12 is not clamped accurately at this time and there is a deviation. After the curved screen assembly 12 is calibrated, the first calibration arm 19 and the second calibration arm 20 loosen the fastening bolts 10, and then the first cylinder 14 runs to extend the output shaft, driving the lifting plate 15, the pressure plate 16 and the first calibration arm 19, the second calibration arm 20 to rise. At this time, the conveying plate 5 together with the curved screen assembly 12 are no longer constrained by the first calibration arm 19 and the second calibration arm 20. Then, the conveyor belt 4 runs to transport the conveying plate 5 together with the curved screen assembly 12 to the inside of the film box 2 to the bottom of the dust removal and cleaning mechanism. At the same time, the mobile lifting mechanism runs to cooperate with the dust removal and cleaning mechanism to remove dust from the curved screen assembly 12.

[0048] The specific process of dust removal and cleaning of the curved screen assembly 12 is as follows: the first linear motor 31 moves along the first linear guide rail 30. After the first linear motor 31 reaches directly below the conveying plate 5, the third cylinder 33 extends the output shaft, the first lifting plate 35 rises and contacts the conveying plate 5, and the first positioning column 34 is inserted into the positioning hole 11. As the first lifting plate 35 continues to rise, the conveying plate 5 is sent into the middle of the film box 2. At the same time, the fifth cylinder 40 extends the output shaft downward to drive the cleaning plate 41 to descend. It should be noted that the bottom end surface of the cleaning plate 41 is provided with a groove matching the curved screen assembly 12. And the cleaning plate 41 is located above the sticky sticker, so as the cleaning plate 41 descends, the cleaning plate 41 presses the sticky sticker down on the surface of the curved screen assembly 12, and the sticky sticker sticks away the dust on the surface of the curved screen assembly 12. When the sticky sticker is pressed down, the two rotating motors 42 run at the same time to drive the reel 43 to rotate and release the sticky sticker. After the dust collection work is completed, in order to ensure that the dust attached to the sticky sticker will not cause secondary pollution, the two rotating motors 42 run again to make one reel 43 release the sticky sticker and the other reel 43 reel up the sticky sticker, so that the clean area where the sticky sticker has not been used is located directly below the cleaning plate 41.

[0049] After the curved screen assembly 12 has completed dust removal and cleaning, the first lifting plate 35 drops back to the initial height, and the conveying plate 5 falls on the conveyor belt 4 again. It should be noted that when the conveying plate 5 is moved by the conveyor belt 4, the side plates 3 limit the two sides of the conveying plate 5, so that the conveying plate 5 can only move left and right along the conveyor belt 4 without deviation. Next, the conveyor belt 4 runs again to transport the conveying plate 5 to the bottom of the lifting film laminating mechanism, and the lifting film laminating mechanism applies film to the curved screen assembly 12. The specific process is as follows: the second linear motor 46 runs and moves along the second linear guide rail 45, so that the sixth cylinder 44 reaches the top of the box body 48, and then the sixth cylinder 44 runs to extend the output shaft so that the negative pressure suction head 47 extends into the storage chamber 49, and the negative pressure suction head 47 absorbs the topmost curved screen tempered film 50 from the storage chamber 49. Then, the second linear motor 46 and the sixth cylinder 44 operate to restore the initial position. At this time, the curved screen tempered film 50 that is sucked away is just above the curved screen assembly 12. Then, the sixth cylinder 44 operates to extend the output shaft downward. During the process, the first linear motor 31 of the mobile lifting mechanism also reaches directly below the curved screen assembly 12 and pushes the curved screen assembly 12 upward through the third cylinder 33. Finally, the curved screen tempered film 50 is pressed down and attached to the curved screen assembly 12 to complete the film pasting.

[0050] During the film laminating process, when the mobile lifting mechanism pushes the curved screen assembly 12 upward, the conveying plate 5 is blocked by the limit block 28 and can only rise to a certain height. After the film laminating is completed, the mobile lifting mechanism supports the conveying plate 5 and the curved screen assembly 12 to move forward. During the process, the smoothing roller 27 smoothes the curved screen assembly 12 after the film is laminating.

[0051] After the conveying plate 5 passes over the smoothing roller 27, the first lifting plate 35 of the mobile lifting mechanism drops back to the initial height, and the lifting film-applying mechanism also returns to the initial position, and the conveyor belt 4 runs again to transport the conveying plate 5 to the bottom of the image detection mechanism. During the process, the first linear motor 31 of the mobile lifting mechanism also reaches the bottom of the curved screen assembly 12 and pushes the curved screen assembly 12 upward to the middle of the film-applying box 2 through the third cylinder 33. At this time, the image detection mechanism detects the curved screen assembly 12 after film-applying from multiple angles at different heights, that is, the camera 59 is used to collect the attached image of the curved screen tempered film 50 on the curved screen assembly 12, and then the collected image is uploaded to the background control terminal, and the background control terminal performs image recognition on the image to determine whether the film-applying is qualified. It should be noted that image recognition is an existing well-known technology, and image recognition is achieved through a series of steps, including image acquisition, preprocessing, feature extraction, model training and testing, etc. First, image data is acquired through devices such as cameras 59 and sensors; then, the image is preprocessed such as scaling, cropping, and rotating to ensure data consistency and adaptability; then, key feature information in the image, such as color, texture, shape, etc., is extracted; finally, a machine learning or deep learning model is used for training so that the model can learn and understand the features in the image, thereby realizing recognition and classification of targets in the image.

[0052] The specific process of the image detection mechanism capturing images of the curved screen assembly 12 after film application from multiple angles at different heights is as follows: the third linear motor 52 runs up and down along the third linear guide rail 51, thereby changing the height of the camera 59, and the operation of the dual-axis motor 57 can drive the second gear 56 to rotate. Since the second gear 56 is engaged with the second tooth 58 on the arc guide rail 53, the moving seat 54 moves along the arc guide rail 53, thereby changing the inclination angle of the camera 59, thereby completing multi-angle and multi-height image capture of the curved screen assembly 12.

[0053] After the curved screen assembly 12 is inspected, the first lifting plate 35 of the mobile lifting mechanism drops back to the initial height, and the image detection mechanism also returns to the initial position. The conveyor belt 4 runs again to transport the conveyor plate 5 to the top of the feeding lifting mechanism. The feeding lifting mechanism lifts and delivers the curved screen assembly 12 that has completed the film sticking inspection. Specifically, the fourth cylinder 37 drives the second lifting plate 38 to rise, and the second lifting plate 38 contacts the conveyor plate 5. The second positioning column 39 is inserted into the positioning hole 11. As the second lifting plate 38 continues to rise, the conveyor plate 5 and the curved screen assembly 12 thereon reach the preset height. After the staff removes the conveyor plate 5 and the curved screen assembly 12 thereon, they remove the curved screen assembly 12. Then, take down the next curved screen assembly 12 to be inspected and place it on the conveyor plate 5 to continue film sticking. It should be noted that multiple conveyor plates 5 can be placed on the conveying line at the same time. During the process of loading and unloading by the staff, the equipment continues to run to apply film to the curved screen assembly 12, thereby improving the film sticking efficiency.
